<p>I have multiple dataframes (<code>sf</code> objects). Each dataframe contains a <code>geometry</code>, <code>name</code> and <code>probability</code> column. They all have the same extents, but only overlap in some regions.</p>
<p>Here is some example data using two dataframes:</p>
<pre><code>nc<-st_read(
system.file("gpkg/nc.gpkg",
package="sf"),
quiet=TRUE)
a<-nc %>%
select(c('geom')) %>%
slice(1:60) %>%
mutate(probability=runif(n=60,
min=1,
max=100)) %>%
mutate(name='A')
b<-nc %>%
select(c('geom')) %>%
slice(50:100) %>%
mutate(probability=runif(n=51,
min=1,
max=100)) %>%
mutate(name='B')
</code></pre>
<p>I would like to <code>merge</code>/<code>join</code> these two dataframes (<code>a</code> and <code>b</code>), but in the regions where they overlap, I would like to only keep the <code>name</code> where the <code>probability</code> is highest. The new dataframe should contain the <code>name</code> and <code>probability</code>.</p>
<p>How would I start with such a problem?</p>

<p>This is the code in JDK source about return the value of BUF_OFFSET.</p>

</code></pre>
<p>What does BUF_OFFSET field mean in BufferedInputStream?</p>
<p>I check the BUF_OFFSET out in JDK source code
github:<a href="https://github.com/openjdk/jdk/tree/jdk-17%2B35" rel="nofollow noreferrer">https://github.com/openjdk/jdk/tree/jdk-17%2B35</a>
I have asked a question about what JavaFieldStream is in here.But I am still confused about the BUF_OFFSET.</p>
<p>I guess...Maybe BUF_OFFSET is simliar with the param off which is from FileInputStream's read method?</p>
<pre><code>public int read(byte b[], int off, int len) throws IOException {
return readBytes(b, off, len);
}
</code></pre>
<p>In here,off means where the data copys and fills in from C array to the Java array.So BUF_OFFSET means where data fills in JVM?It's just my guess.</p>

<p>I'm writing a app that runs on EC2, and currently moving from <strong>local</strong> to <strong>prod</strong> env.</p>
<p>I've read a few blogs that said I should store the env params in <strong>AWS SSM</strong> instead of <code>export</code> them in the terminal.</p>
<p>My question is that, should I fetch these <code>env variables</code> every time the app makes an API call (I think it's not a good option). Or, should I fetch and then store it somewhere within the app? If so, where should I store these env variables after I've fetched them?</p>
<pre><code>const getParametersResponse = await ssm.getParameters({
Names: [
"Client_key",
"Client_Id"
],
WithDecryption: true
}).promise();
</code></pre>
<p>I should run this fetch function <code>getParametersResponse</code> every time the app makes an API call or I should just run it once and then store it somewhere? If so, where do I store these keys?</p>

<p>I'm trying to find the pixel intensity at the center of bounding box</p>
<p>TO achieve this I'm finding the center coordinates of bounding box and get the pixel intensity of that coordinate as shown below</p>
<pre><code>img_read= cv2.imread(r'image.png')
cv2.rectangle(img_read,(xmin,ymin),(xmax,ymax),(0,0,255),3)
center_x = int((xmin+xmax)//2)
center_y = int((ymin+ymax)//2)
print(center_x,center_y)
cv2.circle(img_read,(center_x,center_y),50,(0,0,255),3)
print('Pixel intensity at:',img_read[center_x][center_y])
plt.imshow(img_read[:,:,::-1])
</code></pre>
<p>when I run this I get error as below</p>
<pre><code>IndexError: index 859 is out of bounds for axis 0 with size 815
</code></pre>
<p>but when I try to draw circle from that point with cv2.circle it draws circle without any errors
How can I access the pixel intensity value at point img_read[center_x][center_y]) ?
I tried with this as well img_read[center_x,center_y] but got same error</p>
<p>any help or suggestion to fix this issue will be appreciated thanks</p>

<p>I started using headless chrome for jenkins integration and changed the code in my base file. but now when i run a test I see multiple chromedrivers are started and the driver doesn't close when the last test is finished.</p>
<p>I didn't have this problem before switching to headless mode.</p>
<p>Here is my TestBase class <a href="https://i.stack.imgur.com/JcdiH.png" rel="nofollow noreferrer">TestBase.class</a></p>
<p>And here is the problem. After all these new chromedrivers the test runs successfully, but a lot of chromedriver accumulates in the background.
<a href="https://i.stack.imgur.com/IE2aX.png" rel="nofollow noreferrer">problem</a></p>
<p>I tried to use driver.close and driver.quit functions in the test's @After method but it didn't work like old times too. After using headless mode, I can't close them because as you can see there are multiple chromedrivers in the background.</p>

However I want to keep the latest commit <code>39b6b1d894d0788fdfc09947e1a5f88bf962b142</code> as master.</p>
<p>I should rollback and make new branch?</p>

<p>Starting to learn to code and I was doing the fantasy items exercise from automate boring stuff with python. I tried comparing each item of the addedItems array to the dictionary keys to see if they exist, if not I would create a new key with the default value 1. However it says that I have index out of range error, although creating a regular for loop and testing the array it seems to iterate without a problem, what am I missing?</p>
<p>`</p>
<pre><code>def displayInventory(inventory):
print("Inventory: ")
item_total = 0
for k, v in inventory.items():
item_total += v
print(v, k)
print("Total number of items: " + str(item_total))
def addToInventory(inventory, addedItems):
items = []
amount = []
print(addedItems)
for keys, values in inventory.items():
items.append(keys)
amount.append(values)
for i in range(len(addedItems)):
for j in range(len(inventory)):
if addedItems[i] == items[i]:
inventory[items[j]] =+ 1
else:
inventory.setdefault(addedItems[i], 1)
inv = {'gold coin': 42, 'rope': 1}
dragonLoot = ['gold coin', 'dagger', 'gold coin', 'gold coin', 'ruby']
inv = addToInventory(inv, dragonLoot)
displayInventory(inv)
</code></pre>
<p>`
Here is the error message</p>
<pre><code>['gold coin', 'dagger', 'gold coin', 'gold coin', 'ruby']
---------------------------------------------------------------------------
IndexError Traceback (most recent call last)
<ipython-input-54-b83d92c005f4> in <module>
26 inv = {'gold coin': 42, 'rope': 1}
27 dragonLoot = ['gold coin', 'dagger', 'gold coin', 'gold coin', 'ruby']
---> 28 inv = addToInventory(inv, dragonLoot)
29 displayInventory(inv)
<ipython-input-54-b83d92c005f4> in addToInventory(inventory, addedItems)
19 for i in range(len(addedItems)):
20 for j in range(len(inventory)):
---> 21 if addedItems[i] == items[i]:
22 inventory[items[j]] =+ 1
23 else:
IndexError: list index out of range
</code></pre>
<p>I tried testing index i in regular for loops and it iterated through the items without issue, I am not sure why it says out of range.</p>
<p>EDIT: Solved! Thank you very much!!!</p>

<p>Google play store team mentioned that they found <strong>our app is not compliant with how REQUEST_INSTALL_PACKAGES permission is allowed to be used. Specifically, the use of the permission is not directly related to the core purpose of the app.</strong></p>
<p>But no where in our app, we have used REQUEST_INSTALL_PACKAGES permission but still it was rejected multiple times.</p>
<p>We have added below code snippet in android manifest to remove the REQUEST_INSTALL_PACKAGES from our build and sent for play store review. We have verified in the build permissions and could n't find REQUEST_INSTALL_PACKAGES but, still it was rejected by play store.</p>
<p>Please let us know if anyone faced this issue and how can we rectify this error and make our build approved by Play store team.</p>

<p><strong>What am I trying to achieve:</strong></p>
<p>I have a collectionView which represents events in a timeline. These cells (events) have description label that is constrained to the left edge.</p>
<p>When scrolling to events to the left on the timeline, some events are too wide and are not showing the description label immediately (i must scroll to the very beginning of the cell on timeline to see it)</p>
<p>The idea was to setup constraints between cells label to collectionView frame so that you could see event description immediately, but these are different view hierarchies.</p>
<p>What would be the best way to approach this?</p>
<p><strong>What i have tried:</strong></p>
<p>Setting up the constraint crashes the app:
<code>Terminating app due to uncaught exception 'NSGenericException', reason: 'Unable to activate constraint with anchors <NSLayoutXAxisAnchor:0x600002cbe700 "UILabel:0x11ef0ea20.leading"> and <NSLayoutXAxisAnchor:0x600002cbf240 "UILayoutGuide:0x6000000289a0'UIScrollView-frameLayoutGuide'.leading"> because they have no common ancestor. Does the constraint or its anchors reference items in different view hierarchies? That's illegal.'</code></p>
<p><strong>Additional Info:</strong></p>
<p>UICollectionViewCompositionalLayout:</p>
<pre><code>UICollectionViewCompositionalLayout { sectionIndex, layoutEnvironment in
let item = data.items[sectionIndex]
let contentWidth = data.contentWidth
return context.coordinator.layout(item, contentWidth)
}
</code></pre>

<pre><code>var layout: (Item, CGFloat) -> NSCollectionLayoutSection = { item, contentWidth in
let groupSize = NSCollectionLayoutSize(widthDimension: .absolute(contentWidth), heightDimension: .absolute(100))
let itemSizes = item.items.map { NSCollectionLayoutItem(layoutSize: .init(widthDimension: .absolute(CGFloat($0.duration)), heightDimension: .absolute(100)))}
let group = NSCollectionLayoutGroup.horizontal(layoutSize: groupSize, subitems: itemSizes)
group.interItemSpacing = .fixed(0)
group.contentInsets = .init(top: 0, leading: item.leftGap, bottom: 0, trailing: item.rightGap)
let section = NSCollectionLayoutSection(group: group)

descriptionTimeLabel.bottomAnchor.constraint(equalTo: containerView.bottomAnchor, constant: -10).isActive = true
descriptionTimeLabel.leadingAnchor.constraint(equalTo: containerView.leadingAnchor, constant: 10).isActive = true
}
}
</code></pre>
<p>Just to remind whole point is to make labels of cell visible immediately as the wide cell being revealed and be continously updated so when the cell is fully visible label's leadingAnchor and containerView leadingAnchor equals 10</p>

<li><p><code>osdt_cert.jar</code></p>
</li>
<li><p><code>osdt_core.jar</code></p>
</li>
<li><p>I made sure every environement variable paths are correct, every access rights correctly set.</p>
</li>
<li><p>I believe the connection string syntaxe is correct since it does find the tnsnames.ora and attempt a connexion to the right host, port, sid.</p>
</li>
<li><p>I omitted the field jdbc_password in the jdbc input as it is not required and I don't want jdbc to think I want to use it. I left the jdbc_user field but empty as it is apparently required even though I'm trying not to use it.</p>
</li>
<li><p>I'm able to connect to the database using sqlplus as follow :</p>
</li>
</ul>
<p><code>sqlplus /@name_high</code></p>
<p>So I am at my wit's end (however short that is). If anyone is able to point out what I am missing, I would be immensely grateful !</p>

<p>I have 2 questions concerning re-writting queries, so that no subquery is needed.</p>
<ol>
<li>Is it - using Oracle-SQL-statements - possible to write one of the following queries without using any type of subquery (e.g. subselect)?</li>
<li>If yes, how would this be possible.</li>
</ol>
<p>Query #1 is as follows:</p>
<pre><code>SELECT Stufe, (SELECT AVG(Stufe) FROM Charaktere) FROM Charaktere
WHERE Stufe > (SELECT AVG(Stufe) FROM Charaktere) ORDER BY Stufe DESC
</code></pre>
<p>Query #2 is as follows:</p>
<pre><code>SELECT d.Name, (d.Lebenspunkte-e.Gruppenschaden) as Zustand FROM (
SELECT c.Name, k.Schwächen, (k.Basisleben * c.Leben_Multiplikator) as Lebenspunkte FROM Charaktere c
INNER JOIN Klassen k
ON c.Klasse = k.Klasse) d
INNER JOIN (
SELECT Klasse, SUM(Schaden) as Gruppenschaden FROM Charaktere

<p>I have a script generating a dataframe with multiple columns named with numbers 1, 2, 3 –> n</p>
<p>I want to rename the columns with the following names: "Cluster_1", "Cluster_2", "Cluster_3" –> "Cluster_n" (with incrementation).</p>
<p>As the number of columns in my dataframe can change accordingly to another part of my script, I would like to be able to have a kind of loop structure that would go through my dataframe and change columns accordingly.</p>
<p>I would like to do something like:</p>
<pre class="lang-r prettyprint-override"><code>for (i in colnames(df)){
an expression that would change the column name to a concatenation of "Cluster_" + i
}
</code></pre>
<p>Outside the loop context, I generally use this expression to rename a column:</p>
<pre class="lang-r prettyprint-override"><code>names(df)[names(df) == '1'] <- 'Cluster_1'
</code></pre>
<p>But I struggle to produce an adapted version of this expression that would properly integrate in my for loop with a concatenation of string and variable value.</p>
<p>How can I adjust the expression that renames the column of the dataframe to integrate in my <code>for</code> loop?</p>
<p>Or is there a better way than a <code>for</code> loop to do this?</p>

<h2>Problem</h2>
<p>I was trying to implement a clean prisma transaction architecture with a DDD architecture.
My problem is that i want to be able to perform <code>transactions</code> cross different modules without need to pass the <code>prisma</code> transaction client to each repository
ie:</p>
<pre class="lang-js prettyprint-override"><code>// repository layer
@injectable()
export class UserRepository{
constructor(@inject(PrismaClient) private prisma: PrismaClient)
save(user: IUser): Promise<User>{
return this.prisma.user.create({data: user});
}
}
@injectable()
export class OrderRepository{
constructor(@inject(PrismaClient) private prisma: PrismaClient)
save(order: IOrder): Promise<Order>{
return this.prisma.order.create({data: order});
}
}
</code></pre>
<pre class="lang-js prettyprint-override"><code>// service layer
export class UserService{
constructor(@inject(UserRepository) private userRepo: UserRepository)
create(request: CreateUserRequest){
return this.userRepo.save(request);
}
}
export class OrderService{
constructor(@inject(OrderRepository) private orderRepo: OrderRepository)
create(request: CreateOrderRequest){
return this.orderRepo.save(request);
}
}
</code></pre>
<pre class="lang-js prettyprint-override"><code>// controller layer
export UserController{
constructor(
@inject(UserService) private userService: UserService,
@inject(OrderService) private orderService: OrderService
){}
placeOrder(
userRequest: CreateUserRequest,
orderRequest: CreateOrderRequest
){
// perform transaction, if any fails go with rollback
// !THIS ACTUALLY DOESN'T WORK
prisma.$transaction([
await this.userService.create(userRequest),
await this.orderService.create(orderRequest)
])
}
}
</code></pre>
<p>I want to figure out a clean way to achieve this, has anyone faced a similar problem before?</p>
<p>Thank you all!</p>

<p>I'm brand new to this, 10 days in.
Ive been thinking how I could solve this for 30 min. Please help.</p>
<blockquote>
<h2>Find Average</h2>
<p>You need to calculate the average of a collection of values. Every value will be valid number. The average must be printed with two digits after the decimal point.</p>
<h3>Input-</h3>
<p>On the first line, you will receive N - the number of the values you must read
On the next N lines you will receive numbers.</p>
<h3>Output-</h3>
<p>On the only line of output, print the average with two digits after the decimal point.</p>
<pre><code>Input
4
1
1
1
1
Output
1.00
Input
3
2.5
1.25
3
Output
2.25
</code></pre>
</blockquote>
<p>From what I see, I figure I need to create as much inputs as the N of the first one is and then input the numbers Id like to avarage and then create a formula to avarage them. I may be completely wrong in my logic, in any case Id be happy for some advice.</p>
<p>So far I tried creating a while loop to create inputs from the first input. But have no clue how to properly sintax it and continue with making the new inputs into variables I can use</p>
<pre><code>a=int(input())
x=1
while x<a or x==a:
float(input())
x=x+1
</code></pre>

<p>I read <a href="https://en.cppreference.com/w/c/language/main_function" rel="nofollow noreferrer">main function</a>, and came across following words:</p>
<blockquote>
<p>The main function has several special properties:</p>
<ol>
<li>A prototype for this function cannot be supplied by the program.</li>
</ol>
</blockquote>
<p>Then I wrote a simple program:</p>
<pre><code># cat foo.c
int main(void);
int main(void)
{
return 0;
}
</code></pre>
<p>And compiled it:</p>
<pre><code># gcc -Wall -Wextra -Wpedantic -Werror foo.c
#
</code></pre>
<p>All seems OK! So I am little confused about how to understand "A prototype for this function cannot be supplied by the program". Anyone can give some insights?</p>

<p>I have a df with 6 columns. I want to find the delta based on the date and also group by first few columns.</p>
<pre><code>df <- data.frame (col1 = c('A1','A1','A1','A2','A2','A2','A1','A1','A1','A2','A2','A2','A2','A2','A2'),
col2 = c('B1','B2','B3','B1','B2','B3','B1','B2','B3','B1','B2','B3','B1','B2','B3'),

group_by(col1,col2,col3,col4) %>%
mutate(diff = col6 - lag(col6, default = first(col6,default = 0), order_by = col5))

<p>Expected output is :</p>
<pre><code>df11 <- data.frame (col1 = c('A1','A1','A1','A2','A2','A2','A1','A1','A1','A2','A2','A2','A2','A2','A2'),

)
</code></pre>
<p>I am facing an issue if the value in the previous col4 is not there , then it does not subtract the value. I mean it should treat the missing value as 0. I tried giving first default as 0. But somehow the last three diff values are 0 instead of 60.
Please guide where I am going wrong.</p>
<p>Row 3 has value in Col4 as D22 which is not there for date 01/01/2022 so 30 should be there. similary row 13,14,15 does not have corresponding value for date 01/01/2021. So diff col should have 60 .</p>
<p>Thanks & Regards,
R</p>

<p>I have successfully installed an AWS CLI on WSL. In addition I did follow these instructions:
<a href="https://aws.amazon.com/blogs/compute/introducing-the-c-lambda-runtime/" rel="nofollow noreferrer">https://aws.amazon.com/blogs/compute/introducing-the-c-lambda-runtime/</a></p>
<p>Now, the first example works and when I run a testcase all is functioning properly and the test succeeds. However, when I run the example from the link above with the encoder with a test, the execution fails.</p>
<p>This is the error log:</p>
<pre><code>s2n_init() failed: 402653268 (Failed to load or unload an openssl provider)

</code></pre>
<p>Now, there are two hints in here:</p>
<ol>
<li>failed to load or unload an openssl provider</li>
<li>something with certificates seen the location where the error occured. This location is my local machine which I Find odd since the (binary) code is uploaded to AWS and running there, not on my local machine I'd assume?</li>
</ol>
<p>Have I missed an installation step somewhere or is my configuration incorrect? What can I do to provide more information for myself and / or solve the issue?</p>

<p>I have async operation, in which I call a non-void method:</p>
<pre><code>var result = _controller.SendInvoice(this.ParentForm);
</code></pre>
<p>I was getting error <strong>"Cross-thread operation not valid: Control 'ParentForm' accessed from a thread other than the thread it was created on"</strong></p>
<p>I've managed to fix it by writing code like this:</p>
<pre><code>ParentForm.Invoke(new MethodInvoker(delegate { _controller.SendInvoice(ParentForm); }));
</code></pre>
<p>The problem is that I have to get the return result of the method SendInvoice, but the "solution" above does not solving it for me because it doesn't return value from SendInvoice() method.</p>

<p>I have a YAML file with 2 documents</p>
<pre><code># template.yaml
a : 1
---
b : 2
</code></pre>
<p>I'm trying to edit the YAML file inplace. I've tried using</p>
<pre><code># yq4
yq -i '
select(documentIndex == 0) |
.a = 3 |
select(documentIndex == 1) |
.b = 4
' template.yaml
</code></pre>
<p>But figured out that this outputs an empty file. I figured that the output of <code>select(documentIndex == 0) | .a = 3</code> is a single document, which when piped to <code>select(documentIndex == 1)</code>, results in an empty document.</p>
<p>In yq3, I can do this by writing</p>
<pre><code>#yq3
yq w -d1 .a 3 | yq w -d2 .b 4` > template.yaml
</code></pre>
<p>Is there an equivalent to this yq4 command in yq3?</p>

<p>So let's say, i want to do something thing like this</p>
<pre><code>a = ['AB', 'CD']
s = '1. \n'
print(s.join(a))
</code></pre>
<p>Expected Output:</p>
<pre><code>1. AB
2. CD
</code></pre>
<p>Actual Output:</p>
<pre><code>AB1.
CD1.
</code></pre>
<p>So my question is,
How can i add something at the beginning of the string <code>s</code>?
And also increase the number.</p>
<p>example:</p>
<pre><code>1. ...
2. ...
</code></pre>

<p>I tried using <code>Transform.scale</code> as parent Widget but it doesn't match with that i want.
How should I increase Switch width? or any other suggestion for create similar(like Toggle or ...)?</p>

<p>I'm trying to run a react project cloned from <strong>Github</strong> that works with <code>NodeJs</code>. In the <code>.readme</code> file, the dev tells that i just need to run <code>npm start</code> in backend folder, then on frontend folder.</p>

<p>In backend folder:</p>

<p>I know this is a stupid question, but I'm asking as a newbie to flutter.</p>
<p>I created a getData() method to call Firebase's User data and display it on the app. And to call it, result.data() is saved as a variable name of resultData.</p>
<p>But as you know I can't use Text('user name: $resultData'). How do I solve this? It's a difficult problem for me, since I don't have any programming basics. thank you.</p>
<pre><code>import 'dart:math';

<p>I am trying to write some synchronization code for a java app that runs on each of the cassandra servers in our cluster (so each server has 1 cassandra instance + our app). For this I wanted to make a method that will return the 'local' cassandra node, using the java driver.</p>
<p>Every process creates a cqlSession using the local address as contactPoint. The driver will figure out the rest of the cluster from that. But my assumption was that the local address would be its 'primary' node, at least for requesting things from the system.local table. This seems not so, when trying to run the code.</p>
<p>Is there a way in the Java driver to determine which of the x nodes the process its running on?</p>
<p>I tried this code:</p>
<pre><code>public static Node getLocalNode(CqlSession cqlSession) {
Metadata metadata = cqlSession.getMetadata();
Map<UUID, Node> allNodes = metadata.getNodes();
Row row = cqlSession.execute("SELECT host_id FROM system.local").one();
UUID localUUID = row.getUuid("host_id");
Node localNode = null;
for (Node node : allNodes.values()) {
if (node.getHostId().equals(localUUID)) {
localNode = node;
break;
}
}
return localNode;
}
</code></pre>
<p>But it seems to return random nodes - which makes sense if it just sends the query to one of the nodes in the cluster. I was hoping to find a way without providing hardcoded configuration to determine what node the app is running on.</p>

<p>I'm trying to create an app that uses drf-api-key for authorization. And I want to monitor which api key used in every connection used to database, Is there a way to that?</p>
<p>I tried to get the value of headers.get("Authorization") I get a none value, I just want to retrieve the name of api key used or the prefix of it.</p>

<p>I have a string query</p>
<pre><code>const query = '(travel OR explore OR vacation OR trip) NOT (app OR agency) AND flight';

<p>I want to store the words inside "NOT" block in an array.
What could be the most effective approach for this?</p>
<p>Expected result - ["app", "agency"]</p>

<p>I am writing a program aiming to flip the card while it is clicked. The javascript code looks like this:</p>
<pre><code>/* card flipping onclick */
import "./Stylesheets/FlipCardStyle.css"
var cards = document.querySelectorAll('.card');
[...cards].forEach((card)=>{
card.addEventListener( 'click', function() {
card.classList.toggle('flipped');
});
});
</code></pre>
<p>And the CSS code works like this:</p>
<pre><code>@import "GridLayouts.css";
.card {
background: transparent;
width: 117px;
height: 200px;
perspective: 1000px; /* Remove this if you don't want the 3D effect */
position: relative;
cursor: pointer;
text-align: center;
transition: transform 0.8s;
transform-style: preserve-3d;
}
.wrapper-horizontal .card {
float: left;
margin-right: -47px;
margin-bottom: 20px;
}
/* Do an horizontal flip when you move the mouse over the flip box container */
.card:hover {
transform: rotateY(180deg) translate(0, 40px);
}
/* Position the front and back side */
.card-face {
position: absolute;
width: 100%;
height: 100%;
-webkit-backface-visibility: hidden; /* Safari */
backface-visibility: hidden;
}
/* Style the front side (fallback if image is missing) */
.card-face-front {
background: url("...") -234px 0px;
}
/* Style the back side */
.card-face-back {
background: url("...");
background-size: 100% 100%;
transform: rotateY(180deg);
}
</code></pre>
<p>The HTML looks like this:</p>
<pre><code><!DOCTYPE html>
<link rel="stylesheet" href="Stylesheets/FlipCardStyle.css">
<link rel="stylesheet" href="Stylesheets/GridLayouts.css">
<link rel="stylesheet" href="Stylesheets/Buttons.css">

<div class="wrapper-horizontal">
<div class="card">
<div class="card-face card-face-front"></div>
<div class="card-face card-face-back"></div>
</div>
<div class="card">
<div class="card-face card-face-front"></div>
<div class="card-face card-face-back"></div>
</div>
<div class="card">
<div class="card-face card-face-front"></div>
<div class="card-face card-face-back"></div>
</div>
<div class="card">
<div class="card-face card-face-front"></div>
<div class="card-face card-face-back"></div>
</div>
<script src="./FlipCard.js"></script>
</div>
<button class="btn">Shuffle</button>
</html>
</code></pre>
<p><strong>Theoretically</strong>, when I clicked the card, js script will invoke the .card.flipped, which would rotate the card over. But it doesn't work... My logic of the code comes from <a href="https://codepen.io/mondal10/pen/WNNEvjV" rel="nofollow noreferrer">https://codepen.io/mondal10/pen/WNNEvjV</a>, it workds on codepen but it doesn't seem to work for me.</p>
<p>Could anyone help me? Thanks a lot!!!</p>

<p>Good day,
I run into the problem then returning DTO object.
I have these classes</p>
<pre><code>public class ProductBase
{
public int Id { get; set; }
public string Name { get; set; }
public string Description { get; set; }
public IEnumerable<ProductVariant> Variants { get; set; }
public int BaseImageId { get; set; } = 0;
}
public class ProductVariant
{
public int Id { get; set; }
public int Quantity { get; set; }
public int ProductBaseId { get; set; }
public ProductBase productBase { get; set; }
public int ProductSizeId { get; set; }
public ProductSize ProductSize { get; set; }
public int ProductColorId { get; set; }
public ProductColor ProductColor { get; set; }
public IEnumerable<ImageVariant> imageVariants { get; set; }
}
public class ProductColor
{
public int Id { get; set; }
public string Color { get; set; }
public IEnumerable<ProductVariant> productVariant { get; set; }
}
public class ProductSize
{
public int Id { get; set; }
public string Size { get; set; }
public IEnumerable<ProductVariant> productVariant { get; set; }
}
</code></pre>
<p>In productBaseRepository I have this call</p>
<pre><code>public async Task<IEnumerable<Models.ProductBase>> GetAllWithVariantsAsync()
{
var result = await _dataContext.ProductBases
.Include(pb => pb.Variants)
.ThenInclude(v => v.ProductSize)
.Include(pb => pb.Variants)
.ThenInclude(v => v.ProductColor)
.ToListAsync();
return result;
}
</code></pre>
<p>I have created DTO convertion function</p>
<pre><code>public static IEnumerable<ProductBaseDTO> ConvertToDto(this IEnumerable<ProductBase> productBases)
{
var returnProductBaseDto = (from product in productBases
select new ProductBaseDTO
{
Id = product.Id,
Name = product.Name,
Variants = product.Variants.ToList(),
Description = product.Description,
BaseImageId = product.BaseImageId,
}).ToList();
return returnProductBaseDto;
}
</code></pre>
<p>But then I call this function from swagger</p>
<pre><code> [HttpGet]
public async Task<ActionResult<List<ProductBaseDTO>>> GetAllProductsWithVariants()
{
var baseProductDomain = await _productBaseRepository.GetAllWithVariantsAsync();
var baseProduct = baseProductDomain.ConvertToDto();
return Ok(baseProduct);
}
</code></pre>
<p>I get that
System.Text.Json.JsonException: A possible object cycle was detected. This can either be due to a cycle or if the object depth is larger than the maximum allowed depth of 32</p>
<p>If I remove variants from call it works, so I need to some how remove Unecessry values from Variants</p>

<p>I'm using a ParentComponent that sets inputs to a ChildComponent.
If the changed input is number, the ngOnChanges hook fires, but if it's an array, it does not.</p>
<p>Can someone tell me what am I doing wrong, or how to make ngOnChanges firing when the array is changed?</p>
<p>Thank you.</p>
<p><strong>child ts:</strong></p>
<pre><code>export class ChildComponent implements OnInit {
@Input() num = 0;
@Input() arr: Array<string> = [];
constructor() { }
ngOnInit(): void {
}
ngOnChanges() {
console.log('input changed');
}
}
</code></pre>
<p><strong>parent ts:</strong></p>
<pre><code>export class ParentComponent implements OnInit {
constructor() { }
num = 0;
arr : Array<string> =[];
ngOnInit(): void {
}
changeNumber() {
this.num = this.num + 1;
}
changeArray() {
this.arr.push('some value');
}
}
</code></pre>
<p><strong>parent html:</strong></p>
<pre><code><button (click)="changeNumber()">change num</button>
<button (click)="changeArray()">change array</button>
<app-child [num]="num" [arr]="arr"></app-child>
</code></pre>

<p>I need help, please be kind I'm a beginner.
I have a nested dict like this:</p>
<pre><code>dict_ = {
"timestamp": "2022-11-18T10: 10: 49.301Z",
"name" : "example",
"person":{
"birthyear": "2002"
"birthname": "Examply"
},
"order":{
"orderId": "1234"
"ordername": "onetwothreefour"
}
}
</code></pre>
<p>How do I get a new dict like:</p>
<pre><code>new_dict = {"timestamp": "2022-11-18T10: 10: 49.301Z", "birthyear": "2002", "birthname": "Examply", "orderId": "1234"}
</code></pre>
<p>I tried the normal things I could google.
But I only found solutions like getting the values without the keys back or it only works for flatten dicts.
Last thing I tried:</p>
<pre><code>new_dict = {key: msg[key] for key in msg.keys() & {'timestamp', 'birthyear', 'birthname', 'orderId'}
</code></pre>
<p>This do not work for the nested dict.
May someone has an easy option for it.</p>

<p>Fairly new to SAS/SQL, and have a query, I've not been able to solve. I apologies if the details of my problems are a bit vague, but due to my job I can't be too detailed about the actual data, or show the actual code I have.</p>
<p>I have a table that's a combination of sales data and backlog/catalogue type data. Within the sales data is a variable that informs which group the sale belongs to. Below is a table that illustrates my data and my intent, i.e creating the Group variable that states which group the sale belongs to. Is there a way within SAS to match the catalogue_code to the group columns and return a new variable that is the column header of the matched column (ideally without the underscore).</p>
<p>Hope that's enough info for someone to point me in the right direction.</p>
<div class="s-table-container">
<table class="s-table">
<thead>
<tr>
<th>catalogue_code</th>
<th>Group_A</th>
<th>Group_B</th>
<th>Group_C</th>
<th>Group</th>
</tr>

<p>I am getting an application crash of my app when I am using mic in my case Microsoft Teams on the background and trying to record an audio inside of my app.</p>
<blockquote>
<p>Terminating app due to uncaught exception 'com.apple.coreaudio.avfaudio', reason: 'required condition is false: IsFormatSampleRateAndChannelCountValid(format)'</p>
</blockquote>
<p>Please refer to the code below:</p>
<pre><code>func startRecording() {
// Clear all previous session data and cancel task
if recognitionTask != nil {
recognitionTask?.cancel()
recognitionTask = nil
}
// Create instance of audio session to record voice
let audioSession = AVAudioSession.sharedInstance()
do {
try audioSession.setCategory(AVAudioSession.Category.record, mode: AVAudioSession.Mode.measurement, options: AVAudioSession.CategoryOptions.defaultToSpeaker)
try audioSession.setActive(true, options: .notifyOthersOnDeactivation)
} catch {
print("audioSession properties weren't set because of an error.")
}
self.recognitionRequest = SFSpeechAudioBufferRecognitionRequest()
let inputNode = audioEngine.inputNode
guard let recognitionRequest = recognitionRequest else {

<p>I am pretty sure that the problem is somewhere here, but not sure how to fix it.</p>
<pre><code>let recordingFormat = inputNode.outputFormat(forBus: 0)

<p>I need to create pathed copy of the class, where calls to one module method are replaced to another module method calls:</p>
<pre><code>module Foo

"foo"
end
end
module Bar
def self.check
"bar"
end
end
class Bark
def call
puts Foo.check
end
end
Bark.new.call => "foo"
Meouw = Bark.dup
...
???
Meouw.new.call => "bar"
</code></pre>
<p>Any ideas how would i achieve that?</p>

<p>I try to create a mock test with monkeypatch. I have a typical service-repository class.</p>
<p>repository_class.py</p>
<pre><code>find_by_id(id):
con.select(....);
</code></pre>
<p>service_class.py</p>
<pre><code>get_details(id):
some pre-process...
item = repository_class.find_by_id(id)
post-process...
return result
</code></pre>
<p>then I try to create a mock test with mocking repository method under service:</p>
<pre><code>def test_bid_on_brand_keyword(monkeypatch):
mock_data = "abc"
monkeypatch.setattr(repository_class, 'find_by_id', mock_data)
ans = service_class.get_details(id)
assert ans is not None
</code></pre>
<p>This doesn’t work. It tries to call real repository method. Any suggestion?</p>

<p>I'm trying to fetch a list of users from a backend API. It all works perfectly unless that once I log the <code>getAllUsers()</code> method in the <code>ngOnInit</code> I get the data, but when I log the variable containing the list of users I get undefined.</p>
<p>Here is my code:</p>
<pre><code>users:User[];
constructor(private userService:UserService) { }
ngOnInit(): void {
this.getAllUsers();
console.log(this.users); // ==> shows undefined
}
getAllUsers() {
this.userService.getAll().subscribe({
next:(data) => {
console.log(data); // ==> shows the result
this.users=data
}
})
}
</code></pre>
<p>Can anyone explain the difference between them? And how can I access the response outside the subscribe method? I'm still new to angular though! thanks in advance!</p>

<p>I'm trying to make it so that properties are easily adjustable using a .ini file.</p>
<p>The problem currently is that currently these properties are defined using the "&global-define". With this the properties are not easily adjustable.</p>
<p>I want to put all of these variables inside of a settings file, and import that settings file inside of the procedure. I was thinking about using a settings.ini file for this.</p>
<p>I hope I can further clarify what I'm trying to achieve down below.</p>
<p>settings.ini</p>
<pre><code>port = 19995
</code></pre>
<p>procedure.p</p>
<pre><code>import settings.ini .
define variable iPort as integer no-undo .
iPort = port .
</code></pre>
<p>Let me know if more explanation is needed.</p>
<p>Thanks in advance</p>
<p>I looked for a solution on the internet but was unable to find one.</p>
<p>A solution I tried was reading the file and based on the propertyName I would assign a variable, however this seems very inefficient when dealing with a high amount of variables. Example shown below:</p>
<pre><code>input from value("settings.ini") .
repeat:
import unformatted vLine.
iIndex = index(vLine, "=") .
cPropertyName = trim (substring (vLine, 1, iIndex - 1)) .
cPropertyValue = trim (substring (vLine, iIndex + 1)) .
case cPropertyName:
when "port" then
if cPropertyValue <> "" then iPort = cPropertyValue .
else iPort = "" .
end case.
end.
input CLOSE.
</code></pre>
<p>Another solution I found was:
<a href="https://community.progress.com/s/article/is-it-possible-to-set-custom-variables-in-an-ini-file-to-use-with-abl-code" rel="nofollow noreferrer">https://community.progress.com/s/article/is-it-possible-to-set-custom-variables-in-an-ini-file-to-use-with-abl-code</a></p>
<p>But as stated in the comments this solution only works for windows.</p>
<p>I now have a new solution which makes use of a temp-table:
procedure.p</p>
<pre><code>define temp-table ttSettings no-undo
field port as integer .
temp-table ttSettings:read-json ("file", "settings.json").
find first ttSettings .
message ttSettings.port view-as alert-box.
</code></pre>
<p>settings.json</p>
<pre><code>{
"port": 19995
}
</code></pre>

<p>I have to implement a method named <em>groupBy</em> which has the following signature:
<code>groupBy : (a -> b) -> List a -> List ( b, List a )</code>.</p>
<p>The method takes as input a function and a list of items and returns a list of tuples in the form (b, List a), i.e. it returns some kind of dictionary in which the <strong>key</strong> is the value <strong>b</strong> of the function applied to an item <strong>a</strong> in the input list, and the <strong>value</strong> is an array of items for which the function applied on has the same value. The function given as a parameter is the <em>criteria</em> by which the elements are <em>grouped by</em>. The following examples should make it more clear.</p>
<p>It should return the following results for the give tests:</p>
<ul>
<li><code>groupBy .x [ { x = 1 } ] --> [(1, [{x = 1}])]</code></li>
<li><code>groupBy (modBy 10) [ 11, 12, 21, 22 ] --> [(1, [11, 21]), (2, [12, 22])]</code></li>
<li><code>groupBy identity [] --> []</code>.</li>
</ul>
<p>I'm not sure what the 'identity' input means, but I suppose that it is an input for which the method should return the same array which was given as the second parameter.</p>
<p>I've tried the following code and I almost managed to get the result, but I'm stuck and I have no ideas of how I should continue:</p>
<pre><code>groupBy : (a -> b) -> List a -> List ( b, List a )
groupBy criteria list =
let
unique lst =
List.foldl
(\a uniques ->
if List.member a uniques then
uniques
else
uniques ++ [a]
)
[]
lst
keys =
list
|> List.map criteria
|> unique
pairs =
List.map2 Tuple.pair (List.map criteria list) list
filtered_list =
List.filterMap (\x -> criteria x == keys)
group kl lst =
case kl of
[] -> []
k::ks ->
(k, []):: (result els)
in
[]
-- Debug.todo "Implement groupBy in Util.elm"
</code></pre>
<p>If I run the following code in <strong>elm repl</strong>:
<code>List.map2 Tuple.pair (List.map (modBy 10) [ 11, 12, 21, 22 ]) [ 11, 12, 21, 22 ]</code>, then I get the result:
<code>[(1,11),(2,12),(1,21),(2,22)]</code></p>
<p>The <strong>unique</strong> function returns a list of unique elements (basically a set) given a list which contains duplicates.
The <strong>pairs</strong> function creates tuples of (<strong>b</strong>, <strong>a</strong>) form, but I'm trying to get to the form (<strong>b</strong>, List <strong>a</strong>).
The other two functions don't work, they're just attempts for trying to get to the final form.</p>

<p>Bicep can be used to create a role assignment as follows:</p>
<pre><code>resource RoleAssignment 'Microsoft.Authorization/roleAssignments@2020-10-01-preview' = {
name: guid(managementGroup().id, RoleDefinitionId, principalId)
properties: {
roleDefinitionId: roleDefinition.id
principalId: principalId
principalType: principalType
}
}
</code></pre>
<p>Where the principal type is 'ServicePrincipal', it seems the application id from the Enterprise Application page of the Azure portal is required:</p>
<p><a href="https://i.stack.imgur.com/XSmKo.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/XSmKo.png" alt="enter image description here" /></a></p>
<p>Does anyone know how to acquire this programatically? If it's not possible using bicep then perhaps PowerShell?</p>

<p>Let's say I have the following options structure</p>
<pre class="lang-cs prettyprint-override"><code>using System.ComponentModel.DataAnnotations;
public record AzureOption
{
public AzureGraphOption? Graph { get; init; }
}
public record AzureGraphOption
{
public AzureGraphSecretOption? Secret { get; init; }
}
public record AzureGraphSecretOption
{
[Required] public string TenantId { get; init; }
[Required] public string ClientId { get; init; }
[Required] public string ClientSecret { get; init; }
}
</code></pre>
<p>And an extension class:</p>
<pre class="lang-cs prettyprint-override"><code>using Azure.Core;
using Azure.Identity;
using Microsoft.Extensions.DependencyInjection;
using Microsoft.Extensions.Options;
using Microsoft.Graph;
public static class AzureServiceExtensions
{
// Add Azure services so we can query the Microsoft Graph and resolve membership for automatic group assignment
public static IServiceCollection AddAzureServices(this IServiceCollection services)
{
services.AddAzureOptions();
// Add a Azure Token Credentials based on "static" credentials
// Requires a working Azure app and approvals for several permissions.
// The app does not have to be operating on behalf of the user.
services.AddScoped<TokenCredential>(provider =>
{
var azureOption = provider.GetRequiredService<IOptionsMonitor<AzureOption>>().CurrentValue;
return new ClientSecretCredential(
azureOption.Graph?.Secret?.TenantId,
azureOption.Graph?.Secret?.ClientId,
azureOption.Graph?.Secret?.ClientSecret,
new TokenCredentialOptions
{
AuthorityHost = AzureAuthorityHosts.AzurePublicCloud
});
});
// Add the Microsoft Graph Service, based on the Azure Token
services.AddScoped(provider => new GraphServiceClient(provider.GetService<TokenCredential>(),
new[] { "https://graph.microsoft.com/.default" }));
return services;
}
public static IServiceCollection AddAzureOptions(this IServiceCollection services)
{
services.AddOptions<AzureOption>()
.BindConfiguration("Azure")
.ValidateDataAnnotations()
.ValidateOnStart();
return services;
}
}
</code></pre>
<p>And a small utility extension class:</p>
<pre class="lang-cs prettyprint-override"><code>using Microsoft.Extensions.Configuration;
public static class ServiceCollectionExtensions
{
public static IConfigurationBuilder AddSecretConfig(this IConfigurationBuilder config)
{
config.AddJsonFile("appsettings.Secret.json", true, true);
return config;
}
}
</code></pre>
<p>We can also bootstrap a little ASP.NET Core app for testing, if you will:</p>
<pre class="lang-cs prettyprint-override"><code>using WebApplication = Microsoft.AspNetCore.Builder.WebApplication;
var builder = WebApplication.CreateBuilder(args);
builder.Configuration.AddSecretConfig();
builder.Services
.AddAzureServices();
var app = builder.Build();
app.Run();
</code></pre>
<p>I also have a small structure of secret file stored as <code>appsettings.Secret.json</code> in web root:</p>
<pre class="lang-json prettyprint-override"><code>{
"Azure": {
"Graph": {
"Secret": {
"TenantId": "30cbfa3f-a625-436a-90ff-e90c3fe8bb8e",
"ClientId": "37c72790-ee45-4090-a749-c3ff61c43df8",
"ClientSecret": "qqBGA~5QYza42ABjeWx4o-kAQPJKAGD38wVXCR7Y"
}
}
}
}
</code></pre>
<p>It all went good and well, until I decided to delete the secrets:</p>
<pre class="lang-json prettyprint-override"><code>{
"Azure": {
"Graph": {
"Secret": {
}
}
}
}
</code></pre>
<p>However, the app still runs, and does not validate for the fields of <code>Azure:Graph:Secret</code>, because it is now <code>null</code> instead. Thus the <code>Required</code> validations attached on the fields never runs. If you have added a wrong property in <code>Azure:Graph:Secret</code>, this will happen too:</p>
<pre class="lang-cs prettyprint-override"><code>var azureOption = provider.GetRequiredService<IOptionsMonitor<AzureOption>>().CurrentValue;
var tenant = azureOption.Graph.Secret.TenantId; // What???! it is null???!
</code></pre>
<p>Of course, this is not desirable. I wanted to have this run dynamically:</p>
<pre><code>var azureOption = provider.GetRequiredService<IOptionsMonitor<AzureOption>>().CurrentValue;
var tenant = azureOption.Graph.Secret.TenantId; // Throws an exception `Required value is not set` instead, while I don't have to handle nullable
</code></pre>
<p>One can always choose to add the nested options to match:</p>
<pre class="lang-cs prettyprint-override"><code> public static IServiceCollection AddAzureOptions(this IServiceCollection services)
{
services.AddOptions<AzureOption>()
.BindConfiguration("Azure")
.ValidateDataAnnotations()
.ValidateOnStart();
services.AddOptions<AzureGraphSecretOption>()
.BindConfiguration("Azure:Graph:Secret")
.ValidateDataAnnotations()
.ValidateOnStart();
return services;
}
</code></pre>
<p>But doing so is very tedious especially when you have tons of options.</p>

<p>I am new at FLutter and I want to try to make authorization but I don't know how to do it properly.</p>
<p>I have multiple screens with inputs</p>
<p>First screen: Choose country in textFormField => Second screen: type name, email in textFormFields => Third screen: type and confirm password in textFormFields</p>
<p>And when I press sign up button, I should send country, name, email and password to a server.</p>
<p>But where to store values of previous screens. Should I just transfer all data from one screen to another using navigator, or there is a better solution?</p>
<p>I know in React exists redux or mobX(state manager) but do we have something similar in flutter?</p>

<p>I want to change the color of the first p element, in the example I presented first-child would work as I understand but, in the project I am working there are actually more elements, and more could be added, therefore I would like to avoid ever using it. I need to only change the first element of type p in a given div.</p>
<p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
<div class="snippet-code">
<pre class="snippet-code-css lang-css prettyprint-override"><code>.test p:first-of-type{
background-color:red
}</code></pre>
<pre class="snippet-code-html lang-html prettyprint-override"><code><!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Document</title>

<div class="test">

<p>I have to run a one-line batch command in my Python script.</p>
<p>Currently, I am saving my command in a <code>.bat</code> file and executing the <code>.bat</code> file using the <code>subprocess</code>. But I want to omit the <code>.bat</code> file and directly include the command in my <code>python</code> script. Because I might need to use different bat files for different use cases. I would prefer to use one dynamic python script than save multiple <code>.bat</code> files.</p>
<p>bat command:</p>
<p><code>"C:\Program Files (x86)\temp\FL.B5.exe" /s /a "C:\Users\kuk\Downloads\B5+Typ B.2.asc" /o "C:\Users\kuk\Download\B5+Typ B.2.docx"</code></p>
<p>Python script was:</p>
<pre><code>import subprocess as sp
sp.call([r"C:\Users\kuk\Downloads\test.bat"])
</code></pre>
<p><strong>What I want is:</strong></p>
<pre><code>import subprocess
exe = r"C:\Program Files (x86)\temp\FL.B5.exe"
input = r"C:\Users\kuk\Downloads\B5+Typ B.2.asc"
output = r"C:\Users\kuk\Downloads\B5+Typ B.2.docx"
cmd = '{} /s /a {} /o {}'.format(soft,var1,var2)
subprocess.call(cmd)
</code></pre>
<p>I don't know what is wrong, but unable to execute the script.</p>
<p>Any help would be appreciated!!</p>

<p>I'm following a guide in which <code>api routes</code> are built like so:</p>
<p>1 create <code>server/api/route.js</code> file:</p>
<pre><code>export default defineEventHandler((event) => {

message: `hello api route`
}

</code></pre>
<p>2 use api route in component like so:</p>
<pre><code><script setup>
const { data: message } = await useFetch('/api/route')
</script>
<template>
<div>
<p>api data {{ message }}</p>
</div>
</template>
</code></pre>
<p>This works but when I try to add a <code>query parameter</code> in <code>1.</code>:</p>
<pre><code>export default defineEventHandler((event) => {
const { name } = useQuery(event)
return {
message: `hello api name parameter ${name}`
}
})
</code></pre>
<p>and call it in a component <code>2.</code>:</p>
<pre><code><script setup>
const { data: message } = await useFetch('/api/route?name=mario')
</script>
<template>
<div>
<p>api data {{ message }}</p>
</div>
</template>
</code></pre>
<p>the <code>message</code> property is empty. It seems that <code>useQuery(event)</code> produces an empty variable. Any idea why this is not working?</p>

<p>It's been 3 months I learn ReactJS + TypeScript. My question is about to use react-hook-form (v7) for editing a form. I want to use my custom component that I created and found how to do it by myself !</p>
<p><em>Here is a part of my form provider with react-hook-form</em></p>
<pre><code>import { FormProvider, useForm } from 'react-hook-form';
import { useNavigate, useParams } from 'react-router-dom';
import InputText from 'components/commons/form/InputText';
import { supabase } from 'configs/supabase';
const EditEducation: React.FC = () => {
const { educationId } = useParams();
const [education, setEducation] = useState<education>();
const getEducation = async (educationId: string | undefined) => {
try {
const { data, error } = await supabase
.from('tables1')
.select('data1, data2')
.eq('id', educationId)
.single();
if (error) {
seterror(error.message);
}
if (data) {
return data;
}
} catch (error: any) {
alert(error.message);
}
};
useEffect(() => {
getEducation(educationId).then((data) => {
setEducation(data);
});
// eslint-disable-next-line
}, [educationId]);
const methods = useForm();
const onSubmit = async (formData: any) => {
const updateData = {
data1 = formData.data1,
data2 = formData.data2
};
try {
setSaving(true);
const { error } = await supabase.from('educations').update(updateData);
if (error) {
seterror(error.message);
}
if (!error) {
navigate('/experiences/education');
}
setSaving(false);
} catch (error: any) {
seterror(error.message);
}
};
return (
...
<FormProvider {...methods}>
<form className="p-4" onSubmit={methods.handleSubmit(onSubmit)}>
<InputText
id="data1"
label="Data1"
placeholder="Ex: data1"
defaultValue={education?.data1}
options={{ required: 'This field is required' }}
/>
<Button type="submit">{saving ? 'Saving' : 'Save'}</Button>
</form>
</FormProvider>
...
)
};
</code></pre>
<p><em>Here is my custom component :</em></p>
<pre><code>import React, { useEffect } from 'react';
import { useFormContext } from 'react-hook-form';
interface InputProps {
id: string;
label: string;
placeholder?: string;
defaultValue?: string;
}
const InputText: React.FC<InputProps> = ({
id,
label,
placeholder,
defaultValue,
options,
...rest
}: InputProps) => {
const {
register,
setValue,
formState: { errors }
} = useFormContext();
useEffect(() => {
if (defaultValue) setValue(id, defaultValue, { shouldDirty: true });
}, [defaultValue, setValue, id]);
return (
<div className="">
<label htmlFor={id} className="">
{label}
</label>
<input
type="text"
placeholder={placeholder}
className=""
id={id}
defaultValue={defaultValue}
{...register(id, options)}
{...rest}
/>
{errors[id] && (
<p className="">
<span className="">*</span> {errors[id]?.message}
</p>
)}
</div>
);
};
export default InputText;
</code></pre>
<p>As you can see, I had use a formContext because I want to deconstruct my code into smaller components.</p>
<p>Now I'm having some doubts if I correctly code, specialy when I use ut editing forms : if set my default value via "defaultValue" prop, I have to submit (error show) then clique inside the input to change the state in order to clean the error in the input component.</p>
<p>This is why I have add the useEffect hook to clean the input validation error and it's working. What do you think about this ? Is there a better way to manage it (I think Yup it's a cleaner way to set the validation schema) ?</p>
<p>Thanks in advance and sorry for my rusty English. Great day to all and hope my code will help people.</p>
<p>Use <FormProvider {...methods}> and it's working but I do not know if it's a good way to do it.</p>
<p><strong>Edit</strong> : In reality, I have to double submit to get my data so I guess it's not the correct way, any sugestions ?</p>
<p><strong>Edit2</strong> : I have found a "solution" : if I have a defaultValue in my props, I do in my component :</p>
<pre><code> useEffect(() => {
if (defaultValue) setValue(id, defaultValue, { shouldDirty: true });
}, [defaultValue, setValue, id]);
</code></pre>
<p>I do not think it is the better solution ...</p>

<p>I am building a project based on STM32CubeProgrammer API. The filepath is is done like this and you have to input the filename in the code manually.</p>
<pre><code> /* Download File + verification */
#ifdef _WIN32
const wchar_t* filePath = L"../test file/filename.hex";
#else
const wchar_t* filePath = L"../api/test file/filename.hex";
#endif
</code></pre>
<p>I want the program to show a list of available .hex files, ask for a corresponding number and then append the correct filename to the filePath. The goal is to ask for minimal input from user and keep it as simple as possible.</p>
<p>filePath should remain as const wchar_t*.</p>
<p>I wasn't able to find anything working on Google and I am not even sure how and what to search.</p>
<p>How can this be done?</p>

<p>I want to get rid of a module in Python and I use the "pip uninstall " command. However, for some reason the module is still importable! I am using VS code on a Mac OS. Here is the screenshot of the code:</p>
<p><a href="https://i.stack.imgur.com/bw2Ki.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/bw2Ki.png" alt="enter image description here" /></a></p>
<p>As you can see, the yellow warning says the polars package is not installed (because I already excuted the uninstall command) however in the cell below it, the polars module has been imported succesfully! Can anyone explain what is happening and how can I completely remove the module so it is not importable anymore?</p>

<p>I am working on a project which have to do image predictions using artifical intelligence,
<a href="https://i.stack.imgur.com/NYnbW.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/NYnbW.png" alt="enter image description here" /></a></p>
<p>this is the image, you can see that the nodes are attached with each other, and first encoding the image and then hidden layer and then decoding layer.</p>
<p>My question is, the real implementation of autoencoder is very difficult to understand, is it possible to do coding of autoencoder nodes like we normaly do in data structures for creating linklist node BST node etc?</p>
<p>I want the code looks easy to understand.</p>
<p>like....</p>
<pre><code>#include <iostream>
using namespace std;
struct node
{
double data[100][100];
struct node *next;
};
class autoencoder
{
struct node *head;
struct node *temp; // to traverse through the whole list
public:
LinkedList()
{
head = NULL;
}
void insert()
{
node *NewNode = new node;
cout << "Enter data :: ";
cin >> NewNode->data[100][100];
NewNode->next = 0;
if (head == 0)
{
head = temp = NewNode;
}
else
{
temp->next = NewNode;
temp = NewNode; // temp is treversing to newnode
}
}
void activation() // some activation function
void sigmoid fucntion // some sigmoid function
}
int main()
{
autoencoder obj;
obj.insertnode()
obj.activation()
obj.sigmoid()
}
</code></pre>
<p>this is sudo code type.
My wquestion is the real autoencoder implementation include so much libraries and other stuff which is not understandable,
is it possible to implement the nodes of autoEncoder like shown in the image?</p>
<p>I have a lot of search but didn't find any solution.
If it is possible please let me know the guidence.
If not please let me noe so that I will waste my time on searching this.</p>

<p>I have folder hierarchy as:</p>
<pre><code>->Project Folder
-Main.py
->modules Folder
->PowerSupply Folder
- PowerSupply.py
- SerialPort.py
</code></pre>
<p>In <code>Main.py</code> I am importing <code>PowerSupply.py</code> with following command</p>
<p><code>from modules.PowerSupply.PowerSupply import *</code></p>
<p>Then inside of <code>PowerSupply.py</code>, I am importing SerilPort.py with following command</p>
<p><code>from SerialPort import SerialPort</code></p>
<p>So, when I try to run the Main.py, PowerSupply.py throw an error in the line <code>from SerialPort import SerialPort</code>. The error is</p>
<pre><code>"Exception has occurred: ModuleNotFoundError
No module named 'SerialPort'"
</code></pre>
<p>When I modify the <code>PowerSupply.py</code> as<br />
<code>from modules.PowerSupply.SerialPort import SerialPort</code>, it is not throwing error. But it don`t seem like a good way to me. Is there any way to solve this error?</p>

<p>I have a list of keywords (each in separate cell), for example:</p>
<p>| Keyword A | (cell C1)
| Keyword B | (cell C2)
| Keyword C | (cell C3)</p>
<p>and I have a formula that searches for these keywords across different worksheets and returns the sum of values corresponding to a given keyword:</p>
<pre><code>=SUM(FILTER(INDIRECT("'"& B6 & "'!G1:G600");INDIRECT("'" & B6 & "'!B1:B600")=A6))
</code></pre>
<p>where A6 contains an in-cell dropdown list of these keywords to choose from and B6 contains an in-cell dropdown list of worksheets to work in (let's say for different months).</p>
<p>Example: When 'Keyword A' is found in worksheet 'January' in column B, find the corresponding value to this keyword in column G; then ultimately sum all of these values for a given worksheet and a given keyword.</p>
<p>Depending on what I choose from the in-cell dropdown list, I get the corresponding sum for a given keyword. However, I'd like to get the total sum of all the keyword values added together, but I can`t seem to make it work. Feels like I'd have to use some equivalent of a for loop to iterate through the list and add up the individual sums, but as far as I'm concerned, there's no looping possible in Google Sheets.</p>
<p>I can, obviously, define these sums for each keyword separately and then add these values together, but as I'm working with large datasets with many keywords, this solution is rather unpleasant.</p>
<p>All suggestions are much appreciated!</p>

<p>When handling exceptions in FastAPI, is there a way to stop the application after raising an <code>HTTPException</code>?</p>
<p>An example of what I am trying to achieve:</p>
<pre class="lang-py prettyprint-override"><code>@api.route("/")
def index():
try:
do_something()
except Exception as e:
raise HTTPException(status_code=500, detail="Doing something failed!")
sys.exit(1)
if __name__ == "__main__":
uvicorn.run(api)
</code></pre>
<p>Raising the <code>HTTPException</code> alone won't stop my program, and every line of code after the <code>raise</code> won't be executed.</p>
<p>Is there a good way to do something like this, or something similar with the same result?</p>

<p>This code block is used to read an excel file and get user data by a given user role. but if the user role does not exist in the excel file, it will return an undefined value. how to de we check that the "user" variable is not undefined or null?</p>
<pre><code> cy.task('getExcelData', Cypress.env('usersFilePath')).then((users) => {
const user = users.find(user => {
return user.userRole === 'userRole';
});
cy.wrap(user).should('not.be.empty');
cy.wrap(user).should('not.be.a',undefined)
cy.wrap(user).should('not.be.a',null)
signIn(user.username, user.password);
});
</code></pre>
<p>cy.wrap(user).should('not.be.empty'); (this part working but not others)</p>
<p>this is the error I got in cypress</p>
<p><a href="https://i.stack.imgur.com/EiqB9.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/EiqB9.png" alt="enter image description here" /></a></p>
<p>so I want know how do we check if the value is null or undefined using cypress commands</p>

<p>I have an integration test that requires a small amount of API credits from a third party. The tests are normally <code>.skip</code>ped, but occasionally I wish to run them and spend the credits.</p>
<p>Right now I manually remove the <code>.skip</code>, run:</p>
<pre><code>npx jest -t 'integration tests'
</code></pre>
<p>...then re-add the <code>.skip</code>. However I'm concerned that I'll accidentally commit the removed <code>.skip</code>, and telling colleagues to remove the <code>.skip</code> before they run the tests is a hassle.</p>
<p>Is it possible to override a Jest <code>.skip</code> from the command line? The <a href="https://jestjs.io/docs/cli" rel="nofollow noreferrer">Jest docs</a> don't mention such a thing but there may be some other way.</p>

<p>I am trying to perform. simple get on influxdb using python. The connection works great and I am able to query several values. However, I have one of them which is reported as <code>homeassistant.autogen.°C</code>. When I try to query it, I always get</p>
<pre><code>influxdb.exceptions.InfluxDBClientError: 400: {"error":"error parsing query: found \u00b0, expected identifier at line 1, char 43"}
</code></pre>
<p>The code that is use is:</p>

results = client.query(r'SELECT "value" FROM homeassistant.autogen."°C" WHERE entity_id = sensor.x_temperature')
</code></pre>
<p>I already tried to escape and pass it through quotes but nothing seems to work.</p>
<p>I cannot change how the value is inserted in influxdb.</p>

<p>My program is supposed to read data forever from provider classes stored in <code>PROVIDERS</code>, defined in the config. Every second, it should check whether the config has changed and if so, stop all tasks, reload the config and and create new tasks.</p>
<p>The below code raises <code>CancelledError</code> because I'm cancelling my tasks. Should I really try/catch each of those to achieve my goals or is there a better pattern?</p>
<pre class="lang-py prettyprint-override"><code>async def main(config_file):
load_config(config_file)
tasks = []
config_task = asyncio.create_task(watch_config(config_file)) # checks every 1s if config changed and raises ConfigChangedSignal if so
tasks.append(config_task)
for asset_name, provider in PROVIDERS.items():
task = asyncio.create_task(provider.read_forever())
tasks.append(task)
try:
await asyncio.gather(*tasks, return_exceptions=False)
except ConfigChangedSignal:
# Restarting
for task in asyncio.tasks.all_tasks():
task.cancel() # raises CancelledError
await main(config_file)

<p>I'm relativley new to python
I have a excel file where i can read,Column A "url" and Column B "name".</p>
<p>In the future the columns will have no "column name" so i need it to read from Column A directly and column B and start iterating from cell 1.</p>
<p>I tried using index_col(0) but can't really seem to get the hang of it.
This is a simple download image script.</p>
<pre><code>import requests
import pandas as pd
df = pd.read_excel(r'C:\Users\exdata1.xlsx')
for index, row in df.iterrows():
url = row['url']
file_name = url.split('/')
r = requests.get(url)
file_name=(row['name']+".jpeg")
if r.status_code == 200:
with open(file_name, "wb") as f:
f.write(r.content)
print (file_name)
</code></pre>
<p>I tried this below without any good result.</p>
<pre><code>url = row['index_col(0)'] #0 for excel column "A"
file_name=(row['index_col(1)']+".jpeg") #1 for excel Column "B"
</code></pre>
<p>Apreciate any support!</p>

<p>I have a table with three Columns:
Column A: name of Item,
Column B: Lowest value of series,
Column C: the Highest value of series.
<a href="https://i.stack.imgur.com/TqlMY.png" rel="nofollow noreferrer">enter image description here</a></p>
<p>What I want to achieve is:</p>
<ol>
<li>Generate series of item sequence from lowest number to highest number per row</li>
</ol>
<p>So Apple 7 9 will yield: "Apple_7", "Apple_8", "Apple_9"</p>
<ol start="2">
<li><p>Concatenate/Join such sequence per row into Column D
So</p>
<div class="s-table-container">
<table class="s-table">
<thead>
<tr>
<th style="text-align: left;">Item</th>
<th style="text-align: center;">From</th>
<th style="text-align: center;">Until</th>
<th style="text-align: left;">Result</th>
</tr>
</thead>
<tbody>
<tr>
<td style="text-align: left;">Apple</td>
<td style="text-align: center;">7</td>
<td style="text-align: center;">9</td>
<td style="text-align: left;">"Apple_7, Apple_8, Apple_9"</td>
</tr>
<tr>
<td style="text-align: left;">Berry</td>
<td style="text-align: center;">3</td>
<td style="text-align: center;">8</td>
<td style="text-align: left;">"Berry_3, Berry_4, Berry_5, Berry_6, Berry_7, Berry_8"</td>
</tr>
</tbody>
</table>
</div></li>
<li><p>Doing it all using one Arrayformula, so that new row added can be automatically calculated.</p>
</li>
</ol>
<p>Here is example sheet: <a href="https://docs.google.com/spreadsheets/d/1R5raKmmt5-aOIorAZGHjv_-fdySKWjCMB_FRQwm1vag/edit#gid=0" rel="nofollow noreferrer">https://docs.google.com/spreadsheets/d/1R5raKmmt5-aOIorAZGHjv_-fdySKWjCMB_FRQwm1vag/edit#gid=0</a></p>
<p>I tried in Column D:</p>
<pre><code>arrayformula(textjoin(", ",true,arrayformula(A3:A&"_"&sequence(1,C3:C-B3:B+1,B3:B,1))))
</code></pre>
<p>Apparently, the sequence function only take value from Column B and join it in first row.</p>
<p>Any help will be appreciated.</p>

<p>I am currently looking into memory allocation in C. The code below should read characters from standard input one by one and write them to string s. First I allocate memory for s using malloc. Initial size: CHUNK_SIZE. The counter variable counts the number of letters entered. After it becomes larger than the current size l of string s, the code should reallocate string s with the new size l + CHUNK_SIZE.</p>
<pre><code>#include <stdio.h>
#include <stdlib.h>
#define CHUNK_SIZE 10
int main(void)
{
int l = CHUNK_SIZE;
// s - is the string where to write letters from stdin
char *s = (char *)malloc(l * sizeof(char));
char *p = s;
// counter for counting entered letters
int counter = 0;
while ((*p++ = getchar()) != '\n') {
counter++;
// reallocate memory if amount of entered letters more than size of s
if (counter > l - 1) {
l += CHUNK_SIZE;
s = (char *)realloc(s, l * sizeof(char));
}
}
*p = '\0';
printf("%s", s);
return 0;
}
</code></pre>
<p>The problem is that it seems that the memory space is being successfully reallocated. But the program does not write the letter to the string after the second reallocation. With CHUNK_SIZE set to 10, only 20 letters are stored.
Entered: <code>This is a string and I like it</code>
Saved to string: <code>This is a string and</code></p>

<p>I'm having an issue with my widget running its <code>FutureBuilder</code> code multiple times with an already resolved <code>Future</code>. Unlike the other questions on SO about this, my <code>build()</code> method isn't being called multiple times.</p>
<p>My future is being called outside of <code>build()</code> in <code>initState()</code> - it's also wrapped in an <code>AsyncMemoizer</code>.</p>
<p>Relevant code:</p>
<pre><code>class _HomeScreenState extends State<HomeScreen> {
late final Future myFuture;
final AsyncMemoizer _memoizer = AsyncMemoizer();
@override
void initState() {
super.initState();
/// provider package
final homeService = context.read<HomeService>();
myFuture = _memoizer.runOnce(homeService.getMyData);
}
@override
Widget build(BuildContext context) {
print("[HOME] BUILDING OUR HOME SCREEN");
return FutureBuilder(
future: myFuture,
builder: ((context, snapshot) {
print("[HOME] BUILDER CALLED WITH SNAPSHOT: $snapshot - connection state: ${snapshot.connectionState}");
</code></pre>
<p>When I run the code, and trigger the bug (a soft keyboard being shown manages to trigger it 50% of the time, but not all the time), my logs are:</p>
<pre><code>I/flutter (29283): [HOME] BUILDING OUR HOME SCREEN
I/flutter (29283): [HOME] BUILDER CALLED WITH SNAPSHOT: AsyncSnapshot<dynamic>(ConnectionState.waiting, null, null, null) - connection state: ConnectionState.waiting
I/flutter (29283): [HOME] BUILDER CALLED WITH SNAPSHOT: AsyncSnapshot<dynamic>(ConnectionState.done, Instance of 'HomeData', null, null) - connection state: ConnectionState.done
...
/// bug triggered
...
I/flutter (29283): [HOME] BUILDER CALLED WITH SNAPSHOT: AsyncSnapshot<dynamic>(ConnectionState.done, Instance of 'HomeData', null, null) - connection state: ConnectionState.done
</code></pre>
<p>The initial call with <code>ConnectionState.waiting</code> is normal, then we get the first build with <code>ConnectionState.done</code>.</p>
<p>After the bug is triggered, I end up with another <code>FutureBuilder</code> resolve <em>without</em> the <code>build()</code> method being called.</p>
<p>Am I missing something here?</p>
<p><strong>Edit with full example</strong></p>
<p>This shows the bug in question - if you click in and out of the TextField, the <code>FutureBuilder</code> is called again.</p>
<p>It seems related to how the keyboard is hidden. If I use the <code>FocusScopeNode</code> method, it will rebuild, whereas if I use <code>FocusManager</code>, it won't, so I'm not sure if this is a bug or not.</p>

<p>I have string like below:</p>
<pre><code>[(.1, apple), (.2, orange), (.3, banana), (.4, jack), (.5, grape), (.6, mango)]
</code></pre>
<p>i need to convert above string to object in python like below:</p>
<p><code>[('.1', 'apple'), ('.2', 'orange'), ('.3', 'banana'), ('.4', 'jack'), ('.5', 'grape'), ('.6', 'mango')]</code></p>
<p>is there any efficient way of converting this either by using regex or any other ways?</p>
<p>Thanks in advance</p>

<p>I am using Google Cloud run for my applications.
I am storing all my secrets in Google Cloud Secret Manager.</p>
<p>To read secrets I do the following:</p>
<pre><code>from google.cloud import secretmanager
import hashlib
def access_secret_version(secret_id, version_id="latest"):
# Create the Secret Manager client.
client = secretmanager.SecretManagerServiceClient()
# Build the resource name of the secret version.
PROJECT_ID = "xxxxx"
name = f"projects/{PROJECT_ID}/secrets/{secret_id}/versions/{version_id}"
# Access the secret version.
response = client.access_secret_version(name=name)
# Return the decoded payload.
return response.payload.data.decode('UTF-8')
def secret_hash(secret_value):
# return the sha224 hash of the secret value
return hashlib.sha224(bytes(secret_value, "utf-8")).hexdigest()
</code></pre>
<p>To write secrets:</p>
<pre><code>from google.cloud import secretmanager
def create_secret(secret_id):
# Create the Secret Manager client.
client = secretmanager.SecretManagerServiceClient()
# Build the resource name of the parent project.
PROJECT_ID = "xxxx"
parent = f"projects/{PROJECT_ID}"
# Build a dict of settings for the secret
secret = {'replication': {'automatic': {}}}
# Create the secret
response = client.create_secret(secret_id=secret_id, parent=parent, secret=secret)
# Print the new secret name.
print(f'Created secret: {response.name}')
</code></pre>
<p>How can I create secrets with tags in Python?</p>

<p>Suppose I have the following string:
<code>const test = "This is outside the HTML tag. <title>How to remove an HTML element using JavaScript ?</title>";</code></p>
<p>I'd like to remove the content within all HTML tags in that string. I have tried doing <code>test.replace(/(<([^>]+)>)/gi, '')</code>, but this only removes the HTML tags rather than all the content within it as well. I would expect the outcome to only be 'This is outside the HTML tag.'.</p>
<p>Is it possible to remove HTML tags <strong>and</strong> its contents within a string?</p>

<p>There is a function that takes the following argument :</p>
<pre><code>int send_message(const char *topic)
</code></pre>
<p>I have a struct :</p>
<pre><code>typedef struct mqtt_topic {
char topic[200];
} mqtt_topic_t;
</code></pre>
<p>and a value that is of the type : <code>mqtt_topic_t *mqtt_topic</code></p>
<p>I am trying to pass <code>mqtt_topic->topic</code> as an argument to the function but it throws an error. How do I convert this data to useful format that I can then use as an argument in my function?</p>
<p>Here is the code snippet :</p>
<pre><code>int mqtt_publish(char message[])
{
int msg_id = 0;
ESP_LOGI(TAG, "MQTT_EVENT_CONNECTED");
mqtt_topic_t *mqtt_topic = get_mqtt_topic();
msg_id = esp_mqtt_client_publish(client,&mqtt_topic->topic, message, 0, 1, 0);
ESP_LOGI(TAG, "sent publish successful, msg_id=%d", msg_id);
return msg_id;
}
</code></pre>
<p>Function Prototype :</p>
<pre><code>int esp_mqtt_client_publish(esp_mqtt_client_handle_t client, const char *topic, const char *data, int len, int qos, int retain);
</code></pre>

<p>Hello guys I got the following code in my app.js:</p>
<pre><code>function App() {
const [theme, setTheme] = useState('light');
const toggleTheme = () => {
if (theme === 'light') {
setTheme('dark');
} else {
setTheme('light');
}
};
useEffect(() => {
document.body.className = theme;
}, [theme]);
return (
<div className={`App ${theme}`}>
<button onClick={toggleTheme}>Toggle Theme</button>
</code></pre>
<p>And the Following Css in my Form:</p>
<pre><code>.form-container {
width: 600px;
height: 750px;
background-color: rgb(54, 118, 139);
border-radius: 8px;
box-shadow: 0 0 15px 1px rgba(0, 0, 0, 0.4);
display: flex;
flex-direction: column;
}
</code></pre>
<p>So How can I change the background-color of my Form When Dark is toggled and When Light is toggled? Im using react coding</p>

<p>I have an issue with push notifications not being received on an iOS device in my Flutter app.</p>
<p>I tried to follow this guide: <a href="https://firebase.flutter.dev/docs/messaging/apple-integration/" rel="nofollow noreferrer">https://firebase.flutter.dev/docs/messaging/apple-integration/</a></p>
<p>Steps I have made to configure my push notifications:</p>
<ol>
<li>Register my APN from developer.apple.com on Firebase Console (Cloud Messaging -> my app)</li>
<li>Used the GoogleServices-Info.plist from firebase</li>
<li>Built the app and uploaded to TestFlight</li>
<li>Asked the user for permission to show notifications on iOS</li>
<li>Copied the fcm token from my app and pasted it into Firebase Console -> Cloud Messaging -> new campaign</li>
<li>Push has not been received by my physical iPhone that has the app installed from TestFlight.</li>
</ol>
<p>I also have made sure I have XCode configured properly and:</p>
<ol>
<li>I have selected Push Notifications and Background Modes (Background fetch, Remote notifications)
<a href="https://i.stack.imgur.com/JFw7K.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/JFw7K.png" alt="enter image description here" /></a></li>
<li>I am using the proper bundle identifier (lol)</li>
<li>My App ID has Push Notifications selected
<a href="https://i.stack.imgur.com/vGOyT.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/vGOyT.png" alt="enter image description here" /></a></li>
<li>My APN key has the Push Notifications Service selected
<a href="https://i.stack.imgur.com/CrfUl.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/CrfUl.png" alt="enter image description here" /></a></li>
</ol>
<p>Any idea on what I am doing wrong? Anyone experienced a similar issue?</p>
<p>EDIT:
This is my <code>AppDelegate.swift</code> file, maybe it's somewhat helpful in resolving my issue (worth mentioning - I didn't touch it, it's generated by flutter I guess):</p>
<pre class="lang-swift prettyprint-override"><code>import UIKit
import Flutter
import FirebaseMessaging
@UIApplicationMain
@objc class AppDelegate: FlutterAppDelegate {
override func application(
_ application: UIApplication,
didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?
) -> Bool {
GeneratedPluginRegistrant.register(with: self)
return super.application(application, didFinishLaunchingWithOptions: launchOptions)
}
override func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
Messaging.messaging().apnsToken = deviceToken
super.application(application, didRegisterForRemoteNotificationsWithDeviceToken: deviceToken)
}
}
</code></pre>
<p>Also have received such an email from Apple when submitted a build to Test Flight:
<a href="https://i.stack.imgur.com/ngnje.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/ngnje.png" alt="enter image description here" /></a></p>

<p>I have to write this code where The function must receive a path to a text file which must contain text composed of only English letters and punctuation symbols and a destination file for encrypted data. Punctuation symbols must be left as they are without any modification and the encrypted text must be written to a different file.
Also, I have to validate the inputs.</p>
<p>I've done most of it but in the first part, where I have to ask for a text, the code isn't accepting spaces or punctuation marks, and as I gather it's because of <code>.isalpha</code>, however I couldn't find a way to fix it.</p>
<p>I'm not sure if I have completed the aforementioned requirements, so any type of feedback / constructive criticism is appreciated.</p>
<pre><code> while True: # Validating input text
string = input("Enter the text to be encrypted: ")
if not string.isalpha():
print("Please enter a valid text")
continue
else:
break
while True: # Validating input key
key = input("Enter the key: ")
try:
key = int(key)
except ValueError:
print("Please enter a valid key: ")
continue
break
def caesarcipher(string, key): # Caesar Cipher
encrypted_string = []
new_key = key % 26
for letter in string:
encrypted_string.append(getnewletter(letter, new_key))
return ''.join(encrypted_string)
def getnewletter(letter, key):
new_letter = ord(letter) + key
return chr(new_letter) if new_letter <= 122 else chr(96 + new_letter % 122)
with open('Caesar.txt', 'a') as the_file: # Writing to a text file
the_file.write(caesarcipher(string, key))
print(caesarcipher(string, key))
print('Your text has been encrypted via Caesar-Cipher, the result is in Caesar.txt')

<p>I have an <code>orders</code> table that has a primary key <code>id</code> column, an <code>order_id</code> column, and a <code>created_date</code> column:</p>
<pre><code>===================================
ORDERS
===================================
id | order_id | created_date
-----------------------------------
1 | 178 | 2022-11-16 09:25:11
2 | 182 | 2022-11-18 08:44:19
3 | 178 | 2022-11-17 11:16:22
4 | 178 | 2022-11-18 14:55:41
5 | 195 | 2022-11-15 09:11:17
6 | 195 | 2022-11-16 21:22:32
7 | 146 | 2022-11-16 16:55:09
8 | 178 | 2022-11-16 04:39:16
9 | 121 | 2022-11-16 01:20:19
</code></pre>
<p>I want to write a query that returns the highest <code>created_date</code> for a specific <code>order_id</code>, so I'm trying to use <code>MAX()</code>. But I would also like to return the <code>id</code> of that highest <code>created_date</code> row. In the example above, let's say that I would like to return the row that fits this criteria for order ID 178:</p>
<pre><code>SELECT MAX(o.created_date),
o.id
FROM orders o
WHERE o.order_id = 178
GROUP BY o.id;
</code></pre>
<p>The problem is that when I write the query like this, I get multiple rows returned. I've tried removing the <code>GROUP BY</code> altogether but aside from that, I cannot wrap my head around what I would need to do to this query to show the following information:</p>
<p><code>4 | 2022-11-18 14:55:41</code></p>
<p>How can I write a PostgreSQL query to show the row with the highest <code>created_date</code> value but also show other information for that row?</p>

<p>I'm kinda new to reactjs and I got a situation where I will have to change a state and then I will need to access the new state value in the same function. Please have a look at the code below,</p>
<pre><code>import { useState } from "react";
import "./styles.css";
export default function App() {
const [state, setState] = useState(true); // default state true
const CallMe = () => {
setState(false); // state change to false
console.log(state); // expecting false but return true
};
return (
<div className="App">
<button onClick={CallMe}>CallMe</button>
</div>
);
}
</code></pre>
<p>When I click the button for first time, I get true when I'm expecting false. Is there anyway, I can do it these thing in a same function like above?</p>

<p>I have a spring-boot app (that implements Spring security) related to react app in the front.
When I do rest calls (GET, POST, ..), it works fine without any issues.
However, When I try to call Stripe checkout from my react app, I get this error :</p>
<blockquote>
<p>Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at <a href="https://r.stripe.com/0" rel="nofollow noreferrer">https://r.stripe.com/0</a>. (Reason: CORS request did not succeed). Status code: (null)</p>
</blockquote>
<p>Here's my code</p>
<p><strong>SecurityConfig.java</strong></p>
<pre><code>protected void configure(HttpSecurity http) throws Exception {
String[] staticResources = {
"/api/clients/authentication/**",
"/api/repas/**"
};
http = http.cors().and().csrf().disable();
http = http
.exceptionHandling()
.and()
.sessionManagement()
.sessionCreationPolicy(SessionCreationPolicy.STATELESS)
.and();
http
.authorizeRequests()
.antMatchers(staticResources).permitAll()
.anyRequest().authenticated();
http.addFilterAfter(jwtFilter, ExceptionTranslationFilter.class);
}
</code></pre>
<p><strong>CorsConfiguration.java</strong></p>
<pre><code>Configuration
public class CorsConfiguration
{
@Bean
public WebMvcConfigurer corsConfigurer()
{
return new WebMvcConfigurer() {
@Override

registry.addMapping("/**")
.allowedMethods("HEAD", "GET", "PUT", "POST", "DELETE", "PATCH","OPTIONS")
.allowedOrigins("https://m.stripe.com/6","https://r.stripe.com/0","http://localhost:3000")
.exposedHeaders("*")
.allowedHeaders("*");
}
};
}
</code></pre>
<p>I tried to put "*" in the allowed origins but it didn't work either.
I tried to create a bean in the security config file to enable cors and deleted the cors configuration file (like below)
but then all the calls, even those to my rest APIs have failed.</p>
<pre><code>@Bean
public CorsFilter corsFilter() {
UrlBasedCorsConfigurationSource source =
new UrlBasedCorsConfigurationSource();
CorsConfiguration config = new CorsConfiguration();
config.setAllowCredentials(true);
config.addAllowedOrigin("*");
config.addAllowedHeader("*");
config.addAllowedMethod("*");
source.registerCorsConfiguration("/**", config);
return new CorsFilter(source);
}
</code></pre>
<p><strong>Update:</strong>
This code in the front is what causes the issue
ProfilPayment.java</p>
<pre><code>export default function ProfilPayment() {

<p>This is an easy question, but I am new to Rails. Simply put, I want to use a route from another model (Score) in my Prediction controller. Once a new prediction is made, I want to redirect to the new_score_path but I keep getting an error -</p>
<pre><code> undefined local variable or method `new_scores_path' for #<PredictionsController:
</code></pre>
<p>I guess I need to somehow reference the Score model in the Predictions Controller but I am not sure how to do this. Here is my create method</p>
<pre><code> def create
@prediction = Prediction.new(prediction_params)
respond_to do |format|
if @prediction.save
user = User.find(@current_user.id)
user.lastcase = user.lastcase + 1
user.save
@user = user
@patient = Patient.find(@current_user.lastcase)
format.html { redirect_to url: new_scores_path, notice: 'Prediction WAS successfully created.' }
format.json { render :new, status: :created, location: @prediction }
else
format.html { render :new, status: :unprocessable_entity }
format.json { render json: @prediction.errors, status: :unprocessable_entity }
end
end
end
</code></pre>
<p>Many thanks for reading.</p>
<p>EDIT</p>
<p>I tried</p>
<pre><code> new_score_path
</code></pre>
<p>and it simply routed me to predictions (i.e. in the index.html.erb file). This was in the address
bar</p>
<pre><code> http://localhost:3000/predictions?notice=Prediction+WAS+successfully+created.&url=%2Fscores%2Fnew
</code></pre>

<p>I'm trying to run a really simple script on an Ubuntu EC2 machine with Selenium.</p>
<p>I put the next piece of code inside a loop since the script should run in the background forever:</p>
<pre><code>from selenium import webdriver
def play():
chrome_options = webdriver.ChromeOptions()
chrome_options.add_argument("--headless")
chrome_options.add_argument("--disable-gpu")
chrome_options.add_argument("--no-sandbox")
chrome_options.add_argument("enable-automation")
chrome_options.add_argument("--disable-infobars")
chrome_options.add_argument("--disable-dev-shm-usage")
try:
driver = webdriver.Chrome(executable_path='/usr/bin/chromedriver', options=chrome_options)
except Exception as e:
with open(f'{os.getcwd()}/error_log.txt', 'a') as f:
f.write(str(datetime.datetime.now()))
f.write(str(e))
</code></pre>
<p>While connected to the instance with ssh, the script runs perfectly, but when disconnected, I get this error:</p>
<pre><code>Message: Service /usr/bin/chromedriver unexpectedly exited. Status code was: 1

<p>After re-connecting, the script works normally again with no touch.</p>
<p>I'm running the script as follow:</p>

<p>Working with external Postgres DB, I have only read permissions, so I have to deal with a poorly designed tables.</p>
<p>I have a table:</p>
<pre><code>CREATE TABLE table (
user_id uuid NOT NULL,
column_a boolean DEFAULT false,
column_b boolean DEFAULT false,
column_c boolean DEFAULT false
);
</code></pre>
<p>The table is designed in such a way that only one of the 3 columns is set to true (or all of them are false).</p>
<p>I need to select the column name which is set to true. Is there an elegant way to achive this?</p>
<div class="s-table-container">
<table class="s-table">
<thead>
<tr>
<th>user_id</th>
<th>column_a</th>
<th>column_b</th>
<th>column_c</th>
</tr>
</thead>
<tbody>
<tr>
<td>u1</td>
<td>F</td>
<td>F</td>
<td>F</td>
</tr>
<tr>
<td>u2</td>
<td>F</td>
<td>T</td>
<td>F</td>
</tr>
</tbody>
</table>
</div>
<pre><code>SELECT WHERE user_id = 'u2'
</code></pre>
<p>should return '<strong>column_b</strong>' in this example (because it is the one that is set to true).</p>
<p>Tried different approaches but can't find an elegant way</p>

<p>hi I have the following code that works just fine but I do not know how to move the matching name files to the same directory. for example I have 3 files with the same name (xml, jpeg, txt) when I move the xml file I want all the files with the same name to move with it. I was looking in the forum and did not find anything.</p>
<pre><code>import shutil
from pathlib import Path
from xml.etree import ElementTree as ET
def contains_drone(path):
tree = ET.parse(path.as_posix())
root = tree.getroot()
for obj in root.findall('object'):
rank = obj.find('name').text
if rank == 'car':
return True
return False
def move_drone_files(src="D:\\TomProject\\Images\\",
dst="D:\\TomProject\\Done"):
src, dst = Path(src), Path(dst)
for path in src.iterdir():
if path.suffix == '.xml' and contains_drone(path):
print(f'Moving {path.as_posix()} to {dst.as_posix()}')
shutil.move(path, dst)
if __name__ == "__main__":
move_drone_files()

<p>I'm working on a program in which i want to store the distance the user walked since pressing a button. I retrieve the distance via geolocator package and display it on screen which works just fine.</p>
<p>I know there are some distanceBetween-Function for locations, but as far as i noticed, they are just calculating the distance between 2 points and not the actual distance the user walked (For example, if the user starts at one point X, walks over to Point Y and back to X would end in comparing start-and endpoint (X to X), which results in distance: 0, but i want the distance X -> Y -> X.</p>
<p>I added following function that calculated the distance based on longitude/latitude.</p>
<pre><code>double distance(Position start, Position current){
return double.parse((acos(sin(start.latitude)*sin(current.latitude)+cos(start.latitude)*cos(current.latitude)*cos(current.longitude-start.longitude))*6371).toStringAsFixed(2));
}
</code></pre>
<p>I call it every frame and store the distance between the current and last gps position.
Works slowly but fine, except one Problem:
<strong>Somewhen, the double suddenly turns into "NaN", and i can't figure out why.</strong>
It's completely random when this occurs - At the beginning, it was always around 0.6, but it also occurred around 4.5 and 0.2, so i think the problem may be somewhere else.</p>
<p>Can anybody help?</p>
<p>Or does anybody knows a built-in-function that can solve the same problem?</p>
<p>I tried parsing the double to only have 2 decimal spaces (Didn't round it before) because i thought the number might just got too many decimal spaces to be displayed, but error still occured.</p>
<p>I have a second task that is happening at the same time each time stamp, so i thought it was hindering retrieving the GPS, so i tried disabling it, but it didn't change anything.</p>

<p>I have this function:</p>
<pre><code>const getXNumberOfDocuments = async function getXNumberOfDocuments(

);
}
/*************************************************** */
throw new Error("STOPPING LOOP AT i=0");
/*************************************************** */
}
return x_number_of_documents;
};
</code></pre>
<p>It usually returns something like this:</p>
<pre><code> const response = [
{
user: {
profile: {
profileImageURL: "https://xxxxxxx.com/xxx.jpeg",
},
},
},
{
user: {
profile: {
profileImageURL: "https://xxxxxxx.com/yyy.jpeg",
},
},
},
{
user: {
profile: {
profileImageURL: "https://xxxxxxx.com/zzz.jpeg",
},
},
},
];
</code></pre>
<p>I am trying to modify <code>profileImageURL</code> in each object:</p>
<pre><code>for (let i = 0; i < x_number_of_documents.length; i++) {
console.log(" ~ file: documentsServices.js ~ line 295 ~ i", i);
x_number_of_documents[i].user.profile.profileImageURL =
"THIS SHOULD ONLY BE MODIFIED FOR i=0 BUT IT IS MODIFIED FOR ALL OF THEM!";
}
</code></pre>
<p>The problem is I find out that when <code>i==0</code>, instead of modifying <code>profileImageURL</code> <strong>ONLY the first object</strong>, it modifies it in <strong>all objects</strong>.</p>
<p>So when I break the loop after <code>i==0</code>, and log all the objects, I see that <code>profileImageURL</code> is the same in all of them:</p>
<pre><code> ~ file: documentsServices.js ~ line 291 ~ x_number_of_documents.length 5
~ file: documentsServices.js ~ line 295 ~ i 0
j, 0
~ file: documentsServices.js ~ line 299 ~ x_number_of_documents[j].user.profile.profileImageURL THIS SHOULD ONLY BE MODIFIED FOR i=0 BUT IT IS MODIFIED FOR ALL OF THEM!

3asba
j, 4
~ file: documentsServices.js ~ line 299 ~ x_number_of_documents[j].user.profile.profileImageURL THIS SHOULD ONLY BE MODIFIED FOR i=0 BUT IT IS MODIFIED FOR ALL OF THEM!
3asba
~ file: documents.js ~ line 204 ~ err Error: STOPPING LOOP AT i=0
</code></pre>
<p>Any idea what's going on?</p>
<hr />
<p>To better explain this, I simplified the snippets above:</p>
<pre><code>x_number_of_documents[0].user.profile.profileImageURL =
"THIS SHOULD ONLY BE MODIFIED FOR i=0 BUT IT IS MODIFIED FOR ALL OF THEM!";
console.log(
" ~ file: documentsServices.js ~ line 308 ~ x_number_of_documents[0].user.profile.profileImageURL",
x_number_of_documents[0].user.profile.profileImageURL
);
console.log(
" ~ file: documentsServices.js ~ line 308 ~ x_number_of_documents[1].user.profile.profileImageURL",
x_number_of_documents[1].user.profile.profileImageURL
);
console.log(
" ~ file: documentsServices.js ~ line 308 ~ x_number_of_documents[2].user.profile.profileImageURL",
x_number_of_documents[2].user.profile.profileImageURL
);
console.log(
" ~ file: documentsServices.js ~ line 308 ~ x_number_of_documents[3].user.profile.profileImageURL",
x_number_of_documents[3].user.profile.profileImageURL
);
console.log(
" ~ file: documentsServices.js ~ line 308 ~ x_number_of_documents[4].user.profile.profileImageURL",
x_number_of_documents[4].user.profile.profileImageURL
);
</code></pre>
<p>So even if I explicitly, changed the first object, this is the result:</p>
<pre><code> ~ file: FILLING profileImageURL for i= 0
~ file: documentsServices.js ~ line 308 ~ x_number_of_documents[0].user.profile.profileImageURL THIS SHOULD ONLY BE MODIFIED FOR i=0 BUT IT IS MODIFIED FOR ALL OF THEM!
~ file: documentsServices.js ~ line 308 ~ x_number_of_documents[1].user.profile.profileImageURL THIS SHOULD ONLY BE MODIFIED FOR i=0 BUT IT IS MODIFIED FOR ALL OF THEM!
~ file: documentsServices.js ~ line 308 ~ x_number_ofdocuments[2].user.profile.profileImageURL THIS SHOULD ONLY BE MODIFIED FOR i=0 BUT IT IS MODIFIED FOR ALL OF THEM!
~ file: documentsServices.js ~ line 308 ~ x_number_of_documents[3].user.profile.profileImageURL THIS SHOULD ONLY BE MODIFIED FOR i=0 BUT IT IS MODIFIED FOR ALL OF THEM!
~ file: documentsServices.js ~ line 308 ~ x_number_of_documents[4].user.profile.profileImageURL THIS SHOULD ONLY BE MODIFIED FOR i=0 BUT IT IS MODIFIED FOR ALL OF THEM!
</code></pre>
<p>So the final result is like this even though I explicitly only modified the first object!</p>
<pre><code>const response = [
{
user: {
profile: {
profileImageURL:
"THIS SHOULD ONLY BE MODIFIED FOR i=0 BUT IT IS MODIFIED FOR ALL OF THEM!",
},
},
},
{
user: {
profile: {
profileImageURL:
"THIS SHOULD ONLY BE MODIFIED FOR i=0 BUT IT IS MODIFIED FOR ALL OF THEM!",
},
},
},
{
user: {
profile: {
profileImageURL:
"THIS SHOULD ONLY BE MODIFIED FOR i=0 BUT IT IS MODIFIED FOR ALL OF THEM!",
},
},
},
];
</code></pre>
<hr />
<p>Strangely enough, if I modify the <code>user</code> instead of <code>x_number_of_documents[0].user.profile.profileImageURL</code>, it modified only the first object:</p>
<pre><code>const response = [
{
user: "THIS SHOULD ONLY BE MODIFIED FOR i=0 BUT IT IS MODIFIED FOR ALL OF THEM!",
},
{
user: {
profile: {
profileImageURL: "https://xxxxxxx.com/yyy.jpeg",
},
},
},
{
user: {
profile: {
profileImageURL: "https://xxxxxxx.com/zzz.jpeg",
},
},
},
];
</code></pre>
<hr />
<p>And if I modify <code>user.profile</code>, I get the same original problem:</p>
<pre><code>const response = [
{
user: {
profile:
"THIS SHOULD ONLY BE MODIFIED FOR i=0 BUT IT IS MODIFIED FOR ALL OF THEM!",
},
},
{
user: {
profile:
"THIS SHOULD ONLY BE MODIFIED FOR i=0 BUT IT IS MODIFIED FOR ALL OF THEM!",
},
},
{
user: {
profile:
"THIS SHOULD ONLY BE MODIFIED FOR i=0 BUT IT IS MODIFIED FOR ALL OF THEM!",
},
},
];
</code></pre>
<p>So this may have something to do with modifying values in embedded documents.</p>
