74,447,805 | <p>I'm trying to retrive a <strong>float value</strong> from a SQL Server database <strong>into a double variable</strong>, I'm using this code:</p>
<pre><code>bool CDataAccess::GetValue(UINT col, double& value)
{
int retCode = SQLGetData(m_hstmt, col, SQL_C_DOUBLE, &value, 0, &m_cbValue);
...
}
</code></pre>
<p>That code was working fine until last week when Windows update KB5019959 was installed; if I uninstall this update everything works fine again.</p>
<p>If I use SQL_C_FLOAT as parameter or change column type to double, it works, but that change will carry a hugh refactor...</p>

74,447,848 | <p>Hi I'm creating a Teams App and im having trouble implementing a DatePicker in one of my screen.
My basic test screen:</p>

74,447,890 | <p>I have a nice piece of C# code which allows me to import data into a table with less columns than in the SQL table (as the file format is consistently bad).</p>
<p>My problem comes when I have a blank entry in a column. The values statement does not pickup an empty column from the csv. And so I receive the error</p>
<blockquote>
<p>You have more insert columns than values</p>

children: [
Container(width: 56, height: 51, child: ImageIcon(AssetImage("assets/images/treadmill.png"))),
SizedBox(width: 20),

crossAxisAlignment: CrossAxisAlignment.start,
children: [
Row(
mainAxisSize: MainAxisSize.max,
mainAxisAlignment: MainAxisAlignment.spaceBetween,
children: const [
Text(
"EQUIPMENT",
style: TextStyle(
fontSize: 16,
fontFamily: "OpenSans",
fontWeight: FontWeight.w600
),
),
ImageIcon(AssetImage("assets/icons/delete.png"), color: Colors.red)

),
Text(

style: TextStyle(
fontSize: 14,
fontFamily: "OpenSans",
fontWeight: FontWeight.normal
),
),
],
)

(ignore the "A" in the word)
<a href="https://i.stack.imgur.com/zm43L.jpg" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/zm43L.jpg" alt="imageFront" /></a></p>
<p>I tried to put expanded, spacer, but all the attempts gave an error.</p>
<p>(I don't want to put SizedBox to make this space because there are several types of cell phone screens)</p>
<p>Why does this happen and what to do?</p>

74,448,042 | <p>I am a contributor to Wikipedia and I would like to make a script with AutoHotKey that could format the wikicode of infoboxes and other similar templates.</p>
<p>Infoboxes are templates that displays a box on the side of articles and shows the values of the parameters entered (they are numerous and they differ in number, lenght and type of characters used depending on the infobox).</p>
<p>Parameters are always preceded by a pipe (<code>|</code>) and end with an equal sign (<code>=</code>). On rare occasions, multiple parameters can be put on the same line, but I can sort this manually before running the script.</p>
<p>A typical infobox will be like this:</p>
<pre><code>{{Infobox XYZ
| first parameter = foo
| second_parameter =
| 3rd parameter = bar
| 4th = bazzzzz
| 5th =
| etc. =
}}
</code></pre>
<p>But sometime, (lazy) contributors put them like this:</p>
<pre><code>{{Infobox XYZ
|first parameter=foo
|second_parameter=
|3rd parameter=bar
|4th=bazzzzz
|5th=
|etc.=
}}
</code></pre>
<p>Which isn't very easy to read and modify.</p>
<p>I would like to know if it is possible to make a regex (or a serie of regexes) that would transform the second example into the first.</p>
<p>The lines should start with a space, then a pipe, then another space, then the parameter name, then <strong>any number of spaces</strong> (to match the other lines lenght), then an equal sign, then another space, and if present, the parameter value.</p>
<p>I try some things using multiple capturing groups, but I'm going nowhere... (I'm even ashamed to show my tries as they really don't work).</p>
<p>Would someone have an idea on how to make it work?</p>
<p>Thank you for your time.</p>

74,448,095 | <p>I'm developing a tab based application with Ionic Framework (version 5). The following error occurs only when I modify the code and the application is automatically reloaded on a page other than the "home page".</p>
<p><a href="https://i.stack.imgur.com/Wu0fH.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/Wu0fH.png" alt="enter image description here" /></a></p>
<p>I have already tried to import the modules <code>CommonModule</code>, <code>FormsModule</code> and <code>IonicModule</code> into the module class of each page but doesn't work, the workaround that makes directives like <code>ngFor</code> work is to reload the application on the home page.</p>
<hr />
<p>Specifically this error occurs in the pages <code>new-article</code>:</p>
<p><code>src/app/pages/new-article/new-article.page.html</code></p>
<pre class="lang-html prettyprint-override"><code> <ion-grid>
<ion-row>
<ion-col *ngFor="let url of artcile.photos"><img [src]="url"/></ion-col>
</ion-row>
</ion-grid>
</code></pre>
<p><code>src/app/pages/new-article/new-article.module.ts</code></p>
<pre class="lang-js prettyprint-override"><code>@NgModule({
imports: [
CommonModule,
FormsModule,
IonicModule,
NewArticlePageRoutingModule
],
declarations: [NewArticlePage]
})
export class NewArticlePageModule {}
</code></pre>
<p>As I said before, it's a tab based application, all pages are handled through the routing module:
<code>src/app/tabs/tabs-routing.module.ts</code></p>
<pre class="lang-js prettyprint-override"><code>const routes: Routes = [
{
path: 'tabs',
component: TabsPage,
children: [
{
path: 'home',
loadChildren: () => import('../pages/home/home.module').then(m => m.HomePageModule)
},
...
{
path: 'new-article',
loadChildren: () => import('../pages/new-article/new-article-routing.module').then(m => m.NewArticlePageRoutingModule)
},
{
path: '',
redirectTo: '/tabs/home',
pathMatch: 'full'
}
]
},
{
path: '',
redirectTo: '/tabs/home',
pathMatch: 'full'
}
];
</code></pre>
<p>If anyone has any suggestions on this I would be grateful.</p>
<hr />
<p><strong>UPDATES</strong></p>
<p>This error can occur when you import <code>component-routing.module</code> instead of <code>component.module</code> into <code>tabs-routing.module.ts</code>.</p>

74,448,100 | <p>I'm confused as to how exactly I would make 9 random numbers add to whatever number the user may input. Let's say the user inputs "200" as the number, how do I make it so that I could get 9 random numbers add up exactly to 200?</p>
<p>Obviously, the code below doesn't work the way I want it to because it's literally just 9 random numbers that don't add up to a specific number. I just have no idea how to get this built properly.</p>
<pre><code>public static void RandomStats()
{
Random RandomClass = new Random();
int[] intRandomStats = {
RandomClass.Next(0, 101),
RandomClass.Next(0, 101),
RandomClass.Next(0, 101),
RandomClass.Next(0, 101),
RandomClass.Next(0, 101),
RandomClass.Next(0, 101),
RandomClass.Next(0, 101),
RandomClass.Next(0, 101),
RandomClass.Next(0, 101)
};
// ...
}

74,448,113 | <p>I need to check the sequence of calling of some methods of a class.</p>
<p>I suppose that my production <code>class A</code> is stored in the following file <em>class_a.py</em>:</p>
<pre class="lang-py prettyprint-override"><code>class A:
__lock = None
def __init__(self, lock):
self.__lock = lock
def method_1(self):
self.__lock.acquire()
self.__atomic_method_1()
self.__lock.release()
def __atomic_method_1(self):
pass
</code></pre>
<p>I need to write a unit test that checks the sequence of calling of the methods of the <code>class A</code> when it is invoked the <code>method_1()</code>.</p>
<p>The check must verify that <code>method_1()</code> calls:</p>
<ol>
<li>as first method: <code>self.__lock.acquire()</code></li>
<li>after that it calls <code>self.__atomic_method_1()</code></li>
<li>and that the last method called is <code>self.__lock.release()</code></li>
</ol>
<h2>A useful hint but not enough</h2>
<p><a href="https://stackoverflow.com/questions/31913232/how-to-unittest-the-sequence-of-function-calls-made-insde-a-fuction-python">This is</a> a very useful link, but it doesn't solve my problem. The solution provided by the link is perfect to verify the calling order of a sequence of functions invoked by an other function. The link shows an example where the function under test and the functions called are all contained in a file called <code>module_under_test</code>.<br />
In my case, however, I have to verify the calling sequence of methods of a class and this difference prevents to use the solution provided by the link.</p>
<h2>A trace that starts from the suggestion</h2>
<p>However I have tried to develop the unit test referring to <a href="https://stackoverflow.com/questions/31913232/how-to-unittest-the-sequence-of-function-calls-made-insde-a-fuction-python">the link</a> and in this way I have prepared a trace of the test file that I can show below:</p>
<pre class="lang-py prettyprint-override"><code>import unittest
from unittest import mock
from class_a import A
import threading
class TestCallOrder(unittest.TestCase):
def test_call_order(self):
# create an instance of the SUT
sut = A(threading.Lock())
# prepare the MOCK object
source_mock = ...
with patch(...)
# prepare the expected values
expected = [...]
# run the code-under-test (method_1()).
sut.method_1()
# Check the order calling
self.assertEqual(expected, source_mock.mock_calls)
if __name__ == '__main__':
unittest.main()
</code></pre>
<p>But obviously I'm not able to complete the method <code>test_call_order()</code>.</p>
<p>I hope I was clear, but don't hesitate to ask other info about the problem.</p>
<p>Thanks</p>

74,448,127 | <p>I have been trying to get a query output formatted in a specific way but I am surely doing something wrong. Could anyone that knows what I am doing wrong give me a hand? Thanks a lot.</p>
<p>I have the following db call:</p>
<pre><code> $sql = "SELECT tbl1.spec_num As spec_num,
IF(tbl1.spec_fld, 'TRUE', 'FALSE') As spec_fld,
tbl2.auth_id As auth_id
FROM spec_table tbl1
JOIN spec_auth tbl2 ON tbl1.id=tbl2.spec_table_id
WHERE tbl1.spec_fld=1
AND tbl2.enb=1;";
</code></pre>
<p>If I run this query in the db (mysql) I get this:</p>
<pre><code>spec_num spec_fld auth_id
123413253242135234213432112345DDDDDDDG TRUE 1234567
123413253242135234213432112345DDDDDDDG TRUE 3423435
123413253242135234213432112345DDDDDDDG TRUE 9234245
</code></pre>
<p>When I make a call to the DB in PHP using PDO I do the following:</p>
<pre><code> $stmt = $connection->prepare($sql);
$stmt->execute();
while ($result = $stmt->fetch(PDO::FETCH_ASSOC)) {
$result_json = json_encode($result);
echo $result_json;
}
</code></pre>
<p>My echo inside the loop shows this:</p>
<pre><code>{"spec_num":"123413253242135234213432112345DDDDDDDG","spec_fld":"TRUE","auth_id":"3423435"}
{"spec_num":"123413253242135234213432112345DDDDDDDG","spec_fld":"TRUE","auth_id":"9234245"}
</code></pre>
<p>But what I need now is to create a variable ($dtp) outside the while loop that looks like this:</p>
<pre><code>$dtp = [
'spec_num' => '123413253242135234213432112345DDDDDDDG',
'spec_fld' => TRUE,
'auth_ids' => [
'1234567',
'3423435',
'9234245',
],
];
</code></pre>
<p>Any ideas on the best way to do this? Thanks again in advance.</p>

74,448,144 | <p>Having the nested list like this:</p>
<pre><code>lst = [[1,3], [], [2,2,4], [], [3,5]]
</code></pre>
<p>I'm trying to fill in the empty lists with a value (let's say 0). I know how can do it if we are flatting the list - so then we can use either list comprehension or some pandas solution, but how is it possible to do not to change the structure of nested list and just fill the values inside <code>lst</code>.</p>
<p>Thank you.</p>

74,448,168 | <p>Whenever I try to make a few divs to make a navigation panel at the top of my page it ends up looking like this
<a href="https://i.stack.imgur.com/Gafio.png" rel="nofollow noreferrer">Current</a>
But I would like those div's side by side, along with that I am unable to put text
I got it side by side at one part but the text would be on the same line as the div and it would push the div's to the left and using <br> wouldn't work
Heres the HTML:</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>#topDivs {

height: 50px;
margin: auto;
width: 25%;
box-sizing: border-box;
color: white;
display: block;
}
.fill-div {
height: 100%;

74,448,184 | <p>Imagine a data set with some time gaps between the records:</p>
<pre><code>datatable(t:datetime , v: int)
[
datetime(2022-01-01 07:00), 3,
datetime(2022-01-01 07:15), 2,
datetime(2022-01-01 07:30), 4,
datetime(2022-01-01 07:45), 1,
datetime(2022-01-01 08:00), 5,
// GAP!
datetime(2022-01-01 10:15), 8,
datetime(2022-01-01 10:30), 3,
datetime(2022-01-01 10:45), 2,
// ALSO GAP!
datetime(2022-01-01 11:30), 1,
]
</code></pre>
<p>I'm trying to find a max value for each record within previous hour, excluding the current iteration hour.
To visualize it, I want to achieve something like that:</p>
<div class="s-table-container">
<table class="s-table">

<p>I've tried modifying the approach suggested in <a href="https://stackoverflow.com/questions/72580497/how-to-create-a-window-of-arbitrary-size-in-kusto">How to create a window of arbitrary size in Kusto?</a> (so using <a href="https://www.stackoverflow.com/">scan()</a> operator) but had problems applying it to the above. Also, I feel like something like <a href="https://learn.microsoft.com/en-us/azure/data-explorer/kusto/functions-library/time-window-rolling-avg-fl?tabs=adhoc" rel="nofollow noreferrer">time_window_rolling_avg_fl()</a> might be useful here, but it seems complex for a simple use-case like above.</p>
<p>I feel like what I want to achieve is relatively simple and obvious, but I am just missing it.</p>

It was one of the best fast food meals I've ever had. 6/25 SLIDES © Mary Meisenzahl/Insider The plant-based protein wasn't meant to be indistinguishable from Taco Bell's signature beef, but "equally cravable," according to Taco Bell's director of global nutrition & sustainability Missy Schaaphok. 22/25 SLIDES © Diana G./Yelp In 2019, Taco Bell North America president Julie Felss Masino publicly said that the chain was relying on its own vegetarian options instead of creating new plant-based meat substitutes.

74,448,255 | <p>I want to find a value in the following nested array <strong>without using loops</strong>:</p>
<pre><code>let children = [
{
name: 'grand 1',
children: [
{
name: 'parent 1.1',
children: [
{
name: 'child 1.1.1',
children: [
// more...
]
},
// more...
],
},
// more...
],
},
// more...
];
</code></pre>
<p>This is what I'd do if I was only searching in the horizontal axis:</p>
<pre><code>let childrenHorizontal = [
{ name: 'grand 1' },
{ name: 'grand 2' },
{ name: 'grand 3' },
// more
];
function findHorizontal(name, childrenHorizontal) {
let [head, ...tail] = childrenHorizontal;
if (head.name === name)
return head;
else if (tail.length)
return findHorizontal(name, tail);
}
</code></pre>
<p>But how do I search the nested array both horizontally and vertically?</p>

74,448,292 | <p>I have created a branch called "multiple_fixes" off my Dev branch and have been working there for a couple weeks. While I was working on my branch, several other people have created branches after I created mine, and have since made pull requests into the Dev branch.</p>
<p>Now, I am ready to merge my changes into Dev, but I have many files that are down-level from the current Dev branch. If I do a Pull Request, I will undo all the other changes that people have checked in.</p>
<p>How do I pull the current changes of Dev into my branch, without over-writing my work?</p>

74,448,304 | <p>I have a list of terms that I've accomplished through a split (<code>split = str_split(terms, "//")</code>), where each element would be a row, and within each element the values of three different columns appear sequentially:</p>
<pre><code>split
[[1]]
[1] "value_col_1_1" "value_col_2_1" "value_col_3_1"
[[2]]
[1] "value_col_1_2" "value_col_2_2" "value_col_3_2"
</code></pre>
<p>I would like to assign each of the values to columns in a dataframe. My first idea was a for loop, but it looks like it is quite inefficient, since it is taking longer than a similar code to accomplish the same task. The loop is the following:</p>
<pre><code>for (row in 1:length(new_categorization)){
df[row, "first_col"] <- split[[row]][1]
df[row, "second_col"] <- split[[row]][2]
df[row, "third_col"] <- split[[row]][3]
}
</code></pre>
<p>What is the most time efficient way to do this?</p>

74,448,333 | <p>There is a use case in which I have a long <code>String</code> which can contain many <code><img></code> tags.
I need to collect the entire image tag from start(<code><img src="</code>) to close(<code>"></code>) in a List.</p>
<p>I wrote a regex(<code>"<img.*?\">"gm</code>) for seleting these but don't know how to collect them all in a List.</p>

<pre class="lang-java prettyprint-override"><code>final String regex = "<img.*?\\\">";
final String string = "Hello World <img src=\"https://dummyimage.com/300.png/09f/777\"> \nMy Name <img src=\"https://dummyimage.com/300.png/09f/ff2\"> Random Text\nHello\nHello Random <img src=\"https://dummyimage.com/300.png/09f/888\"> \nMy Name <img src=\"https://dummyimage.com/300.png/09f/2ff\">adaad\n";
final String replace = "";
final Pattern pattern = Pattern.compile(regex, Pattern.MULTILINE);
final Matcher matcher = pattern.matcher(string);
final String result = matcher.replaceAll(replace); // Here, how can I collect all the image tags in a list

74,448,344 | <p>I have trained a BERTopic model on a dataframe of length of 400k. I want to map the topics of each document in a new column inside the dataframe. I could do that by running a for loop on all the documents and do <code>topic_model.transform(doc)</code> on them. The only problem is, it takes more than a second to transform each document into its topic and it would take days for the whole dataset.</p>
<p>Is there a way to achieve this faster since I want to map the topics on the training data.</p>
<p>I tried:</p>
<pre><code>topic_model = BERTopic()
topics, probs = topic_model.fit_transform(docs)
topic_model.reduce_topics(docs, nr_topics=200)
topics = []
for text in df.texts:
tops = topic_model.transform(text)
topics.append(tops)
df['topics'] = topics

<li>src="/path/image.bmp" // should capture => /path/image.bmp</li>
<li>src="/path/image.jpg" // should capture => /path/image.jpg</li>
<li>src="https://www.site1.com" // should NOT capture</li>

74,448,363 | <p>I am trying to find out if a hex color is "blue". This might be a very subjective thing when comparing different (lighter/ darker) shades of blue or close to blue colors but in my case it does not have to be very precise. I just want to determine if a color is blue or not.</p>
<p>The more generalized question would be, is there a way to calculate which of the "basic colors" is closest to a given hex value? Basic colors being red, blue ,green, yellow, purple, etc. without being too specific.</p>
<p>I am looking for an implementation or library in python but a general solution would also suffice.</p>

74,448,382 | <p>I've got a group of files with <strong>only one</strong> specific extension under one specific directory. How do I check whether I've got at least one of those files. If at least one file with that specific extension is present, then print <em>at least one file matching your extension is present in your directory</em>. If not, then print <em>no files of that specific extension exist in your directory</em>.</p>
<p>Also, when no file of a specific extension is present, I've got the following error message that I'm not able to get rid of, even if I use <code>2>/dev/null</code> redirection: <code>zsh: no matches found: *.mkv</code> (and hence, behaving differently from Bash)</p>

74,448,405 | <p>As mentioned in cppreference: <a href="https://en.cppreference.com/w/cpp/language/copy_elision" rel="nofollow noreferrer">https://en.cppreference.com/w/cpp/language/copy_elision</a></p>
<p>it is guaranteed in c++17 that copy elision must be applied for some cases like</p>
<pre><code>SomeBigObject SomeBigObject::Factory(...) {
SomeBigObject local;
...
return local;
}
</code></pre>
<p>(example taken from <a href="https://abseil.io/tips/11" rel="nofollow noreferrer">https://abseil.io/tips/11</a> )</p>
<p>but not for cases like</p>
<pre><code>SomeBigObject SomeBigObject::Factory(...) {
SomeBigObject local1;
SomeBigObject local2;
...
if (cond_1) {
return local1;
} else {
return local2;
}
}
</code></pre>
<p>For a c++ user, it is somewhat difficult to be 100% sure that copy elision / NVO is applied to the functions' return value above.</p>
<p>So, to be sure that a object would not be copied, we usually write something like</p>
<pre><code> SomeBigObject obj;
func(&obj);
</code></pre>
<p>whereas in most cases a one-liner like</p>
<pre><code> SomeBigObject obj = func();
</code></pre>
<p>would suffice.</p>
<p>Is there any language/compiler facility to help us guarantee that at compile time (maybe some kind of static_assert()) so that we can be confident writing those one-liners ?</p>
<p>I know that marking the copy constructor deleted would do the good, but copy is needed in some cases.</p>

74,448,412 | <p>I hope you are able to help me.</p>
<p>My question is:</p>
<p>When passing an instance of an object that is in an arraylist, and I pass that arraylist to another class, how do I access it's atributes?</p>
<p>I can access the attributes before passing it to another class.</p>
<p>The "Main" class, passes on the data, to the "Employees" class.</p>
<pre><code>Employees employees = new Employees();
employees.addEmployee("Orlando", "Silva", 111111111, "St. King's Street", 111111111, 11111111111111L, employees.getMinimumWage(), employees.getDayShift());
employees.addEmployee("Rui", "Guilherme", 111111111, "St. King's Street", 111111111, 11111111111111L, employees.getMinimumWage(), employees.getNightShift());
employees.addEmployee("Marco", "Alberto", 111111111, "St. King's Street", 111111111, 11111111111111L, employees.getMinimumWage(), employees.getNightShift());
</code></pre>
<p>The "Employees" class receives the data, adds it to an array, and from that array goes to the "AllStaff" class</p>
<p>Notice, that I have access to the atributes, in the method "addToAllStaff()"</p>
<pre><code>public class Employees {
// Atributes
public String name;
private String lName;
private int nID;
private String address;
private int phNum;
private long nSocialSecNum;
private double minimumWage = 740.83;
private double employeeWage;
private String dayShift = "Day shift", afternoonShift = "Afternoon shift", nightShift = "Night shift";
private String shift;
private ArrayList<Employees> employeesArrayList = new ArrayList<Employees>();
private AllStaff allStaff = new AllStaff();
//---------------------
// Constructors
public Employees(){
}
public Employees(String name, String lName, int nID, String address, int phNum, long nSocialSecNum, double minimumWage, String shift){
this.name = name;
this.lName = lName;
this.nID = nID;
this.address = address;
this.phNum = phNum;
this.nSocialSecNum = nSocialSecNum;
this.employeeWage = minimumWage;
this.shift = shift;
//----------------
extraWage();
}
//---------------------
public void addEmployee(String name, String lName, int nID, String address, int phNum, long nSocialSecNum, double minimumWage, String shift){
Employees employee = new Employees(name, lName, nID, address, phNum, nSocialSecNum, minimumWage, shift);
employeesArrayList.add(employee);
addToAllStaff();
}
void addToAllStaff(){
System.out.println("(Class Employees) employees size: " + employeesArrayList.size());
for (int i = 0; i < employeesArrayList.size(); i++){
System.out.println("Employee names: " + employeesArrayList.get(i).getName());
System.out.println("Employee names: " + employeesArrayList.get(i).name);
}
allStaff.addEmployees(employeesArrayList);
}
}
</code></pre>
<p>In the class "AllStaff", is where I don't have access to the attributes</p>
<pre><code>public class AllStaff {
static ArrayList <AllStaff> employeesArrayList;
public AllStaff(){
}
public void addEmployees(ArrayList listOfEmployees){
System.out.println("List of employees size: " + listOfEmployees.size());
for (int i = 0; i < listOfEmployees.size(); i++){
System.out.println("Employee names: " + listOfEmployees.get(i).getName());
System.out.println("Employee names: " + listOfEmployees.get(i).name);
}
this.employeesArrayList = listOfEmployees;
}
</code></pre>

74,448,563 | <p>I am creating react context that requires an initial value like these</p>

{menuWide ? renderTab() : renderResults()}

<p><strong><strong>Question</strong> When writing the default value for the createContext function I have to write a "default" value for the function. <strong>Remember</strong> context is created <strong>Outside</strong> the parent component so I can't access the actual set state function.</strong></p>
<p>My first option was writing null for the function key but I got an error <strong>Type 'null' is not assignable to type 'Dispatch<SetStateAction<Date | null>>'</strong>.</p>
<p>For other properties, I can safely write null and be done with it. For functions it's tricky. Please help.</p>

74,448,566 | <p>This is the workflow I need to accomplish:</p>
<ol>
<li>Validate the date format of all dates in column_1 and column_2.</li>
<li>If date is not in either format: mm/dd/yy hh:mm or mm/dd/yyyy hh:mm</li>
<li><em>Need assistance</em> - Print the non-matching values.</li>
</ol>
<p><strong>Note:</strong> I do not know what format the dates will be in and some will not be dates at all.</p>
<p>Sample input data CSV:</p>
<pre><code>column_1 column_2
8/22/22 15:27 8/24/22 15:27
8/23/22 15:27 Tuesday, August 23, 2022
8/24/22 15:27 abc123
8/25/22 15:27 8/25/2022 15:27
8/26/22 15:27 8/26/2022 18:27
8/26/22 15:27 8/22/22
</code></pre>
<p>The following method always throws an exception, as designed, when the <code>to_datetime()</code> function returns a ValueError. How can I validate the date and then capture the values that <strong>do not</strong> match <strong>format_one</strong> or <strong>format_two</strong>?</p>
<pre><code>df = pd.read_csv('input.csv', encoding='ISO-8859-1', dtype=str)
date_columns = ['column_1', 'column_2']
format_one = '%m/%d/%y %H:%M'
format_two = '%m/%d/%Y %H:%M'
for column in date_columns:
for item in df[column]:
try:
if pd.to_datetime(df[item], format=format_one):
print('format 1: ' + item)
elif pd.to_datetime(df[item], format=format_two):
print('format 2: ' + item)
else:
print('unknown format: ' + item)
except Exception as e:
print('Exception:' )
print(e)
</code></pre>
<p>Output:</p>
<pre><code>Exception:
'8/22/22 15:27'
Exception:
'8/23/22 15:27'
Exception:
'8/24/22 15:27'
Exception:

Exception:
'8/25/2022 15:27'
Exception:
'8/26/2022 18:27'
Exception:
'8/22/22'
</code></pre>
<p>Desired output:</p>
<pre><code>Exception:
'Tuesday, August 23, 2022'
Exception:
'abc123'
Exception:
'8/22/22'
</code></pre>

74,448,602 | <p>I have a multiple tag in my webpage with the same class called price. Each tag is of that form</p>
<pre><code><p class="price">Price: 45$</p>
<p class="price">Price: 32$</p>
</code></pre>
<p>What I need at the end is to separate the price text in a span and the price in another so that it will be like that</p>
<pre><code><p class="price"><span class='h1'>Price:</span> <span class="h2">45$</span></p>
</code></pre>
<p>This is what I do until now but problem is that the span is not a tag but is insert as a simple string</p>
<p><a href="https://i.stack.imgur.com/XOVEU.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/XOVEU.png" alt="enter image description here" /></a></p>

for (let i = 0; i < price.length; i++) {
let priceTitle = price[i].innerText.split(":")[0];
let priceToPay = price[i].innerText.split(":")[1];
price[i].innerText = ''; //Delete content of price
$(".price")[i].append("<span class='h1'>"+ priceTitle+"</span> <span class='h2'>"+ priceToPay +"</span>");
}

<p>Can you help me fix this issue and perhaps optimize the code I already do.</p>

74,448,666 | <p>In Docker compose, is it possible for a container A to wait for a container B to finish (aka, stop running) before starting?</p>
<p>I have 3 containers in my docker compose:</p>
<ul>
<li>Container A is a MySQL database</li>
<li>Container B is a Flyway container that has some SQL migrations on a certain schema1. After running the migrations, it stops.</li>
<li>Container C is a Flyway container that has some SQL migrations on a certain schema2 and adds some data to both schema1 and schema2. It does also stop after running the migrations.</li>
</ul>
<p>I need container C to wait for B to finish otherwise the migrations are going to fail.</p>

74,448,683 | <p>I have some data taken at different time points in wide format, and need to convert it to long format to aid with analysis and to merge it with another dataset.</p>
<p>The format of the data is (where A_0 means value of A at time 0, A_15 means value at time 15):</p>
<pre><code>import pandas as pd
df_wide = pd.DataFrame({'Subject': ['AA', 'BB', 'CC', 'DD'],

df_wide

2 CC 3 4 5 3 4 5 3 4 5
3 DD 4 5 6 4 5 6 4 5 6
</code></pre>
<p>I wish to convert this to long format and generate the variable time as follow:</p>
<pre><code>df_long = pd.DataFrame({'Subject': ['AA', 'AA', 'AA', 'BB', 'BB', 'BB', 'CC', 'CC', 'CC', 'DD', 'DD', 'DD'],
'Time': [0, 15, 30, 0, 15, 30, 0, 15, 30, 0, 15, 30],
'A': [1, 2, 3, 2, 3, 4, 3, 4, 5, 4, 5, 6],
'B': [1, 2, 3, 2, 3, 4, 3, 4, 5, 4, 5, 6],
'C': [1, 2, 3, 2, 3, 4, 3, 4, 5, 4, 5, 6],
})
df_long
</code></pre>
<pre><code> Subject Time A B C
0 AA 0 1 1 1
1 AA 15 2 2 2
2 AA 30 3 3 3
3 BB 0 2 2 2

6 CC 0 3 3 3
7 CC 15 4 4 4
8 CC 30 5 5 5
9 DD 0 4 4 4
10 DD 15 5 5 5
11 DD 30 6 6 6
</code></pre>
<p>I've read the pivot and melt functions but can't quite get my head around it - any assistance would be greatly appreciated.</p>
<p>Have tired pivot and melt but unsure how to generate the time variable.</p>

74,448,687 | <p>I have this custom component in vue callled "dm-vehicle-spec"</p>
<pre><code> <dm-vehicle-spec @_handleRemoveSpec="_handleRemoveSpec" v-for="spec, index in vehicleSpecs" :key="index" :index="index" :spec="spec"></dm-vehicle-spec>
</code></pre>
<p>which looks like the following</p>
<pre><code><script>
export default {
props: ["spec"],
data() {
return {
specName: null,
specValue: null,
}
},
mounted() {
if (this.spec.detail_name && this.spec.detail_value) {

this.specValue = this.spec.detail_value;
}

computed: {
getSpecNameInputName() {
return `spec_${this.spec.id}_name`;
},
getSpecValueInputName() {
return `spec_${this.spec.id}_value`;
},
},
methods: {
_handleRemoveSpec() {
this.$emit("_handleRemoveSpec", this.spec.id);
}
},
}
</script>
<template>
<div class="specs-row flex gap-2 w-full items-center">
<div class="col-1 w-5/12">
<input placeholder="Naam" type="text" :id="getSpecNameInputName" class="w-full h-12 spec_name rounded-lg border-2 border-primary pl-2" v-model="specName">
</div>
<div class="col-2 w-5/12">
<input placeholder="Waarde" type="text" :id="getSpecValueInputName" class="w-full h-12 spec_name rounded-lg border-2 border-primary pl-2" v-model="specValue">
</div>
<div @click="_handleRemoveSpec" class="col-3 w-2/12 flex items-center justify-center">
<i class="fas fa-trash text-lg"></i>
</div>
</div>
</template>
</code></pre>
<p>so when i have 3 specs, 1 from the database and 2 customs i have the following array <strong>vehicleSpecs</strong> (Which i loop over)</p>
<pre><code>[
{"id":23,"vehicle_id":"1","detail_name":"Type","detail_value":"Snel","created_at":"2022-11-07T19:06:26.000000Z","updated_at":"2022-11-07T19:06:26.000000Z","deleted_at":null},
{"id":24},
{"id":25}
]
</code></pre>
<p><a href="https://i.stack.imgur.com/ezLWz.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/ezLWz.png" alt="enter image description here" /></a></p>
<p>so lets say i want to remove the second item from the list so the one with test1 as values, then the array looks like</p>
<pre><code>[{"id":23,"vehicle_id":"1","detail_name":"Type","detail_value":"Snel","created_at":"2022-11-07T19:06:26.000000Z","updated_at":"2022-11-07T19:06:26.000000Z","deleted_at":null},{"id":25}]
</code></pre>
<p>So the second array item is removed and thats correct because object with id 24 no longer exsist but my html shows</p>
<p><a href="https://i.stack.imgur.com/1qPBW.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/1qPBW.png" alt="enter image description here" /></a></p>
<p>that the value for object with id 24 still exists but the value for object with id 25 is removed, how is that possible?</p>
<p>If u need any more code or explaination, let me know</p>
<p>Any help or suggestions are welcome!</p>

74,448,701 | <p>I am currently working on a task where I need to synchronize the data, example:</p>
<p>Client makes a request to get data to the API (API has access to the database), client received the data and saves it to the list. That list is used for some time etc..... Then in the meanwhile another client accesses the same API and database and makes some changes... to the same table... After a while the first client want's to update his current data, since the table is quite big let's say 10 thousand records, grabbing the entire table again is inefficient. I would like to grab only the records that have been modified,deleted, or newly created. And then update the current list the client 1 has. if the client has no records, he classifies all of them as newly created (at start up) and just grabs them all. I would like to do as much checking on the client's side.</p>
<p>How would I go about this ? I do have fields such as Modified, LastSync, IsDeleted. So I can find the records I need but main issue is how to do it efficiently with minimal repetition.</p>
<p>At the moment I tried to get all the rows at first, then after I want to update (Synchronize) I get the minimal required info LastSync Modified IsDeleted Key, from the API, which I compare with what I have on the client and then send only keys of the rows that don't match to the server to get the entire values that match the keys. But I am not sure about efficiency of this also... not sure how to update the current list with those values efficiently the only way I can think of is using loop in loop to compare keys and update the list, but I know it's not a good approach.</p>

How could I select my entire variable? By clicking and dragging I think it takes about 5 minutes :)</p>
<p>This is how I stored my string:</p>
<pre><code>std::string str = "504b0304140000000800b3ab584fd82c4d1ec01b00002a45000007000000"
"4348414e474553955bfb73db4872fed95775ffc364cf1593673e44ca92bd"
"aa3b27b6a4f5ea4eaf58f2de6ea5121c080c499cf03a0c2089fbd7a7bfee"
"...";
</code></pre>
<p>It goes for about 58 thousand lines, how could I select it?</p>

74,448,721 | <p>I have a problem with creating a matrix with user input and rotate it 90 degrees. Anyone knows why there is a problem with the range of the matrix?</p>
<p>The problem is when the elements are entered and it only shows up like 2 or 3 elements even if i write that I want 16..</p>
<pre><code>public static void main(String args[]) {
int m, n, i, j;
Scanner sc = new Scanner(System.in);
System.out.print("Enter the number of rows: ");
//taking row as input
m = sc.nextInt();
System.out.print("Enter the number of columns: ");
//taking column as input
n = sc.nextInt();
// Declaring the two-dimensional matrix
int[][] array = new int[m][n];
// Read the matrix values
System.out.println("Enter the elements of the array: ");
//loop for row
for (i = 0; i < m; i++)
//inner for loop for column
for (j = 0; j < n; j++)
array[i][j] = sc.nextInt();
//accessing array elements
System.out.println("Elements of the array are: ");
for (i = 0; i < m; i++) {
for (j = 0; j < n; j++)
//prints the array elements
System.out.print(array[i][j] + " ");
//throws the cursor to the next line
System.out.println();
System.out.println("The matrix after being rotated 90 degrees clockwise: ");
rotate(array);
}
}
static int M = 4;
// Method to rotate the matrix 90 degree clockwise
static void rotate(int[][] arr) {
// printing the matrix on the basis of the index
for (int j = 0; j < M; j++) {
for (int i = M - 4; i >= 0; i--)
System.out.print(arr[i][j] + " ");

74,448,734 | <p>what is the best way to check the false & true condition in this case, i have a state set to false initially</p>
<pre><code>status: false,
</code></pre>
<p>The status changes to true if a certain props is present (data-widget) do i need to add the ="true" to the attribut?</p>
<pre><code><div id="app" data-widget></div>
// Is it the same thing or i don't need to add the ="true" to the attribut
<div id="app" data-widget="true"></div>
</code></pre>
<p>Here is how i check a condition, i am confused which one i should use :</p>
<pre><code>//Option 1
newData.status = this.props.widget ? true : false
//Option 2
newData.status = (typeof this.props.widget !== "undefined") ? true : false
</code></pre>
<p>Is there a better/correct way to handle the false & true condition?</p>

74,448,753 | <p>I have a (somewhat long) list of words. And a function 1 (linsok(lista, elem)) which asks the user for a word, and if the user-inputted word exists in the list, we get a confirmation in the form of exists/does not exist.</p>
<p>I then have a 2nd function which for any word in the list will create 4 variations of it (creating 4 concatenations of each word) and append these new words to another list. This function will come in handy in my third function, which I am having trouble constructing.</p>
<p>My third function will compare the words in my original list, to the list of my concatenated words. If any word in the concatenated list exists in my orginal list, the function should yield these matches in a list (in the form of [original word, concatenated word] where both are present in the original list). All with the caveat that this third function is to include a function call for the 1st function which asks for user input of a word and produces a confirmation of the word's existence.</p>
<p>I have tried to write the function in the form of for item1 in list 2 and for item2 in list 2 but honestly in pretty lost as to how to construct the function. Especially how/where I am to insert my function call to the first function.</p>
<p>This is the code as it stands now:</p>
<p>`</p>
<pre><code>########## UPPGIFT 1 ##########
#fil = open('ordlista.txt')
lista = open('ordlista.txt').read().split()
#print(lista[::100])
########## UPPGIFT 2 #########
def linsok(lista, elem): #function 1 which returns whether or not a word is present in list
if elem in lista:
print(elem + ' exists')
return True
else:
print(elem + ' exists not')
return False
########## UPPGIFT 3 ##########
def kupering(ord): #function which concatenates the words in question
nylista = []
if ord in lista:
for i in range(len(ord)):
nylista.append((ord[i:len(ord)] + ord[:i]))
#nylista=nylista[1:]
#print(nylista)
return nylista
#def linsok_kup(lista): #funtion 3 which i have trouble with
# def main():
# while elem := input('Ditt ord: '):
# linsok(lista,elem) #u2
#
# #where i would insert my 3rd function
#
# if __name__ == '__main__':
# main()

74,448,782 | <p>I was creating an if-else loop based on the type of variable, to either convert a list of numbers to kilograms, or simply one number, and for some reason I cannot call the variable I created into my main() function. I am a beginner to python and any help would be appreciated.
Here is my code:</p>
<pre><code># Testing Code
def kgToLb(weight):
# Return the converted weight (kg)
newWeight = []
if type(weight) == list:
for w in range(len(weight)):
return newWeight.append(weight[w] * 2.20462)
return newWeight == weight * 2.20462
def main():
weightList = [-22, 11, 0, 8.2, -8.2]
answerKgsList = [-9.979044, 4.989522, 0, 3.71946186, -3.71946186]
# Test data
for w in range(0, len(weightList)):
kgToLb(weightList)
correctWeight = weightList == answerKgsList[w]
print(correctWeight)
print(newWeight)
print("The converted weight is " + str(newWeight[w]) + ". " + str(correctWeight))
main()
</code></pre>
<p>I tried to change the if-else format to see if it would change anything to no avail.</p>

<p>1-) There is no Backup/restore option on the database right click
2-) I've tried to use BACKUP T-SQL with azure storage account and storage url from SSMS but this is not supported.</p>

74,448,821 | <p>I am writing a C function <code>GetDeviceList()</code> which must return a list of device names found as strings somehow. The number of devices found and of course the device names themselves will vary each time the function is called.</p>
<p>How the function gets the device names is not the scope of this question, but inside the <code>GetDeviceList()</code> function, a <code>char*</code> gets updated in a loop with each new device name found. This <code>char*</code> must then be copied to a list which can be read by the caller.</p>
<p>The function, nor the calling function cannot use dynamic memory.</p>
<p>What would be the best way to get a list of those strings returned from the function. I am thinking of a 2-dimensional char array passed as an output paramater, but not sure.</p>

74,448,842 | <p>My (first) web app uses pydub, which depends on ffmpeg. On my local windows environment, I installed ffmpeg and added the path to the ffmpeg executables to the windows "path" environment variables.</p>
<p>It all works locally, but bow that I have deployed my app to PythonAnywhere, the following line in my code is causing an error:</p>
<pre><code> sound.export(export_path, format="mp3", bitrate="128k")
</code></pre>
<p>I believe the error is because this code relies on ffmpeg.</p>
<p>I have read on their forums that ffmpeg is installed for all users on PythonAnywhere. Is there something I need to do to get it to work? Do I need to add the path of the ffmpeg files to the environment variables? I have a .env file with other env variables -- would I need to add something to this?</p>

74,448,864 | <p>How do I enable an arm64 extensions such as FEAT_XNX ?</p>
<p>I'm working on stage 2 page table execution permission on arm64, currently looking into D5.4.6 section of the manual.</p>
<p>It mentions that the XN pair only describe stage 2 controle only when FEAT_XNX is implemented. In my systems it seems that FEAT_XNX is not implemented.</p>
<p>I looked in to MMFR4 and other register to perform the check as mentionned in the manual.</p>
<p>My question would be, how do I "implement" it ? Is it even up to me or it's a feature only available on certain HW ? Can I add this to Qemu ? Could someone explain to me those FEAT_****** things, what is that exactly ? I can't find ressources that talks about it online.</p>
<p>Thanks all</p>

74,448,871 | <p>In a custom function, I want to run an <code>if</code> condition if my vector only has one unique value. I can use <code>length(unique(x)) == 1</code>. However, I think that this could be more efficient: instead of getting all the unique values in the vector and then count them, I could just stop after having found one value that is different from the first one:</p>
<pre class="lang-r prettyprint-override"><code># Should be TRUE
test <- rep(1, 1e7)
bench::mark(
length(unique(test)) == 1,
all(test == test[1])
)
#> Warning: Some expressions had a GC in every iteration; so filtering is disabled.
#> # A tibble: 2 × 6
#> expression min median `itr/sec` mem_alloc `gc/sec`
#> <bch:expr> <bch:tm> <bch:tm> <dbl> <bch:byt> <dbl>
#> 1 length(unique(test)) == 1 154.1ms 158.6ms 6.31 166.1MB 6.31
#> 2 all(test == test[1]) 38.1ms 49.2ms 19.6 38.1MB 3.92
# Should be FALSE
test2 <- rep(c(1, 2), 1e7)
bench::mark(
length(unique(test2)) == 1,
all(test2 == test2[1])
)
#> Warning: Some expressions had a GC in every iteration; so filtering is disabled.
#> # A tibble: 2 × 6
#> expression min median `itr/sec` mem_alloc `gc/sec`
#> <bch:expr> <bch:tm> <bch:tm> <dbl> <bch:byt> <dbl>
#> 1 length(unique(test2)) == 1 341.2ms 386.1ms 2.59 332.3MB 2.59
#> 2 all(test2 == test2[1]) 59.5ms 81.1ms 11.5 76.3MB 1.92
</code></pre>
<p>It is indeed more efficient.</p>
<p>Now, suppose that I want to replace <code>length(unique(x)) == 2</code>. I could probably do something similar to stop as soon as I find 3 different values but I don't see how can I generalize this to replace <code>length(unique(x)) == n</code> where <code>n</code> can be any positive integer.</p>
<p><strong>Is there an efficient and general way to do this?</strong></p>
<p>(I'm looking for a solution in base R, and if you can improve the benchmark for <code>n = 1</code>, feel free to suggest).</p>

}
}
</code></pre>
<p>When I navigate over the navigation menu I see the output of print like:</p>
<pre><code>SETTING 1
SETTING 0
SETTING 1
SETTING 1
</code></pre>
<p>However, page switching does not happen unless I press <code>CRTL+S</code> on the VSCode editor.
Looks like it reads the value of <code>PageService.CurrentPage</code> only on the editor save.</p>
<p>This issue happened once I made <code>PageService.CurrentPage</code> static. Any idea why is that and how can I fix it?</p>

74,448,889 | <p>I'm at a loss here, and I realise I may be going the long way around, but I can't figure it out.
I have a datetime in UTC, curr.
It is not being saved in 24 hr time, so I can convert it to a string s, which is indeed a string in 24 hr time. Now I want to save it back as a datetime still retaining the 24 hr time, but when I write foo out it is still being displayed in 24 hr time. How do I get the current Utc time in not just a DateTime, but a 24 hr DateTime?</p>
<pre><code>var curr = DateTime.UtcNow;
String s = curr.ToString("yyyy-MM-dd HH:mm:ss");
DateTime foo = DateTime.Parse(s);
Console.WriteLine(foo);
Console.ReadLine();
</code></pre>

74,448,892 | <p>I'm trying to create a worker that listens to http requests and adds jobs IDs to a queue. I'm using Python's built-in multiprocessing module for that.</p>
<p>I need a Pool with a few processes that will process the job from queue and respawn. Processes have to restart, bacause for some cases job processing can cause memory leak. Pool should run forever as the items will be added to the queue dynamically.</p>
<p>The problem is that my pool does not respawn workers after they complete.</p>
<p>How can I use pool to achieve this? I want it to run forever, consume item from queue and respawn child after every task.</p>
<pre class="lang-py prettyprint-override"><code>from http.server import BaseHTTPRequestHandler, ThreadingHTTPServer
from multiprocessing import Pool, SimpleQueue, current_process
queue = SimpleQueue()
def do_something(q):
worker_id = current_process().pid
print(f"Worker {worker_id} spawned")
item_id = q.get()
print(f"Worker {worker_id} received id: {item_id}")
# long_term_operation_that_leaks_memory(item_id)
# print(f"Worker {worker_id} completed id: {item_id}")
def main():
with Pool(
processes=2, initializer=do_something, initargs=(queue,), maxtasksperchild=1
):
queue.put("a")
queue.put("b")
queue.put("c")
server_address = ("", 8000)
httpd = ThreadingHTTPServer(server_address, BaseHTTPRequestHandler)
try:
httpd.serve_forever()
except (KeyboardInterrupt, SystemExit):
pass
if __name__ == "__main__":
main()
</code></pre>
<p>I tried with <code>initializer</code> and <code>maxtasksperchild</code> but it does not work.</p>
<p>I know I can add new processes to a pool using map, but I don't have a map of an infinite possible tasks from the future. I think <code>initializer</code> should be responsible for all new tasks. But I don't know how to force it to run forever and respawn.</p>
<p>In my code example "c" item is never processed. Therefore if I add http logic to put more items it will not work either. Adding http logic to this code is not necessary part of my question, but any tips will be welcomed.</p>
<p>Thanks!</p>
<p>Edit:</p>
<p>The reason I decided to use Pool in this case, is that official <a href="https://docs.python.org/3/library/multiprocessing.html#multiprocessing.pool.Pool" rel="nofollow noreferrer">documentation</a> says:</p>
<blockquote>
<p>Worker processes within a Pool typically live for the complete
duration of the Pool’s work queue. A frequent pattern found in other
systems (such as Apache, mod_wsgi, etc) to free resources held by
workers is to allow a worker within a pool to complete only a set
amount of work before being exiting, being cleaned up and a new
process spawned to replace the old one. The maxtasksperchild argument
to the Pool exposes this ability to the end user.</p>
</blockquote>
<p>My goals:</p>
<ul>
<li>Items will be added dynamically to the queue by http requests</li>
<li>Pool will live forever</li>
<li>Worker process will perform only one task from queue and will be respawned</li>
</ul>
<p>Why I used only 2 processes?</p>
<p>Processes number will not be infinite and it is easy to test my example with 2 processes rather that 5 or 10.</p>
<p>Why I put 3 items manually? It is for example purpose, in real solution all items will be added dynamically, so there is no way to loop over them or to use map on them.</p>

74,448,900 | <p>I have a static HTML page at the address <code>https://MyPage/index.html</code></p>
<p>The page contains several images, which are located at

<p>The images are linked in the HTML source code like this:</p>
<p><code>…<span><img width=x height=y src="MyImages/imageXYZ.png"</span>…</code></p>
<p>When a button is clicked or, even better, when the page is loaded, all image links should be rewritten by appending a random number or, for example, the current time in milliseconds, so that the links look like this afterwards:</p>
<p><code>…<span><img width=x height=y src="MyImages/imageXYZ.png?1587624427"</span>…</code></p>

74,448,921 | <p>I have build a result page for a calculation. It's basically a CSS-grid in a DIV. The grid has three columns. In each column there are tiles (divs) which contain tables (which show the results).</p>
<p>In JavaScript I calculate the result tables and assign them to the tables. There is an outermost div where I set display to "table".</p>
<p>Here is the problem: Some browsers on some computers present a long empty page. At the very end I can see a bit of tables, the rest is clipped.</p>
<p>This may happen at the beginning where build the page or when I replace a table by a newly calculated table.</p>
<p>For now I found an unsatisfying work around:
Before any assignments to div.innerHtml I set display of the outermost div to none. After the assignments I set it back to table after a setTimeout of 0.5 sec. Then the page is built properly.</p>
<p>It looks like that after the assignments some time is needed to build the internal DOM structure but I don't know any event to wait for.</p>
<p>Here is the essence of the html structure:</p>
<pre><code><div style="display: table">
<div style="display: grid; grid-template-areas: 'left center right';">
<div style="grid-area: left">
<div id="result_table0"></div>
<div id="result_table1"></div>
</div>
<div style="grid-area: center">
<div id="result_table2"></div>
<div id="result_table3"></div>
</div>
<div style="grid-area: right">
<div id="result_table4"></div>
<div id="result_table5"></div>
</div>
</div>
</div>
</code></pre>
<p>The Javascript assignments of the tables looks similar like that:</p>
<pre><code>// calculation of the table
let my_result_table = '<table><tr><td>xxx</td><td>yyy</td></tr></table>';
// assignment to the div
document.getElementById('result_table0').innerHTML = my_result_table;
</code></pre>
<p>Any ideas what's going wrong here?</p>

74,448,945 | <p>Is there a way to execute <code>DateTime.Parse</code> on a tuple in C#.</p>
<p>I am using Specflow and part of the tests I am executing involve testing a list of <code>DateTime</code> tuples (e.g. <code>List<(DateTime, DateTime)></code>). In this step I am taking in a string, parsing it into a list of strings, where each string represents a <code>DateTime</code> pair separated by <code>=</code>.</p>
<p>The plan was to create a tuple store the value by splitting the string, creating a string tuple, then parsing that tuple using <code>DateTime.Parse</code>.</p>
<p>This doesn't work, giving me a CS1503 error (<em>Argument n: cannot convert from 'type x' to 'type y'</em>), and I cannot find any other information online about using <code>DateTime.Parse</code> on tuples. Is there another way of changing these values into <code>DateTime</code>?</p>
<p>Below is an extract of my code for reference:</p>
<pre class="lang-cs prettyprint-override"><code>public class TimeModeServiceStepDefinitions
{
List<(DateTime, DateTime)> expectedResult = new List<(DateTime, DateTime)>();
[Given(@"I have the following list of expected results: '([^']*)'")]
public void GivenIHaveTheFollowingListOfExpectedResults(string p0)
{
List<string> tuples = p0.Split('|').ToList();
foreach (var tuple in tuples)
{
var timeTuple = (first: "first", second: "second");
timeTuple = tuple.Split('=') switch { var a => (a[0], a[1]) };
expectedResult.Add(DateTime.Parse(timeTuple));
}
}

74,448,964 | <p>I have a long config file which looks like:</p>
<pre><code><some stuff before our example>
'Realtime' => [
'foo' => 'bar',
'enabled' => true,
'lorem' => 'ipsum'
],
<some stuff after our example>
</code></pre>
<p>The above is a large config php file and I was asked to mine the <code>enabled</code> value of 'Realtime` with bash. I could do it with PHP, but I was specifically asked to do it with bash.</p>
<p>I tried the following:</p>
<pre><code>echo $(tr '\n' ' ' < myconfig.php | sed '$s/ $/\n/') | grep -o -P '(?<=Realtime).*(?=\])'
</code></pre>
<p>and this mines the text from the file between <code>Realtime</code> <strong>and the last</strong> <code>]</code>. But I would like to mine the content between <code>Realtime</code> and the first <code>]</code>. For the time being I have implemented a simplistic bash and accompanied that with PHP parser, as follows:</p>
<pre><code> public function getConfig($name)
{
$path = Paths::CONFIG_FILE;
if (!$this->config) {
$this->config = Command_ShellFactory::makeForServer('zl', "cat {$path}")->execute(true, true);
}
$splitName = explode('.', $name);
$lastPosition = 0;
$tempConfig = $this->config;
foreach ($splitName as $currentName) {
if (($position = strpos($tempConfig, $currentName)) === false) {
throw new RuntimeException('Setting was not found');
}
$tempConfig = substr($tempConfig, $position);
}
return trim(explode("=>", explode("\n", $tempConfig)[0])[1], ", \n\r\t\v\x00");
}
</code></pre>
<p>and this works, but I'm not satisfied with it, because it loads the whole file into memory via the shell command and then searches for the nested key (<code>Realtime.enabled</code> is passed to it). Is it possible to improve this code in such a way that all the logic would happen via bash, rather than helping it with PHP?</p>
<p>EDIT</p>
<p>The possible settings to mine could be of any depth. Examples:</p>
<pre><code>[
/*...*/
'a' => 'b', //Depth of 1
'c' => [
'a' => 'd' //Depth of 2
],
'e' => [
'f' => [
'g' =>'h' //Depth of 3
]
]
/*...*/
]
</code></pre>
<p>Theoretically any amount of depth is possible, in the example we have a depth of 1, a depth of 2 and a depth of 3.</p>
<p>EDIT</p>
<p>I have created foo.sh (some fantasy name of no importance):</p>
<pre><code>[
'Realtime' => [
'enabled' => [
'd' => [
'e' => 'f'
],
],
'a' => [
'b' => 'c'
],
]
'g' => [
'h' => 'i'
],
'Unrealtime' => 'abc'
]
</code></pre>
<p>Working one-dimensional command:</p>
<pre><code>sed -Ez ":a;s/.*Unrealtime' => +([^,]*).*/\1\n/" foo.sh | head -1
</code></pre>
<p>The result is</p>
<blockquote>
<p>'abc'</p>
</blockquote>

74,448,975 | <p>Let's say I have a dataframe like this:</p>
<pre><code>import pandas as pd
df = pd.DataFrame([[1,2,3,"P", 1, "A", "SOMETHING"],
[1,2,3,"C", 0, "B", "NOTHING"],
[1,2,3,"C", 0, "B", "SOMETHING"],
[4,5,6,"P", 1, "A", "SOMETHING"],
[4,5,6,"C", 1, "A", "NOTHING"]],
columns=["ID1", "ID2", "ID3", "FLAG", "CONDITION_1", "CONDITION_2", "DATA_FIELD"])
</code></pre>
<pre><code> ID1 ID2 ID3 FLAG CONDITION_1 CONDITION_2 DATA_FIELD
0 1 2 3 P 1 A SOMETHING
1 1 2 3 C 0 B NOTHING
2 1 2 3 C 0 B SOMETHING
3 4 5 6 P 1 A SOMETHING
4 4 5 6 C 1 A NOTHING
</code></pre>
<p>There is a FLAG column which has 2 types of values:</p>
<ul>
<li>P: Parent</li>
<li>C: Child</li>
</ul>
<p>When the ID1, ID2, ID3 values are repeated, this means those records are connected. There is always one P and can be any number of C in the FLAG column.</p>
<p>What I want to achieve is to update the all child record's DATA_FIELD value to the parent record's
value if the following conditions met:
CONDITION_1 == 0 AND CONDITION_2 == "B"</p>
<p>This would give the following result:</p>
<pre><code> ID1 ID2 ID3 FLAG CONDITION_1 CONDITION_2 DATA_FIELD
0 1 2 3 P 1 A SOMETHING
1 1 2 3 C 0 B SOMETHING
2 1 2 3 C 0 B SOMETHING
3 4 5 6 P 1 A SOMETHING
4 4 5 6 C 1 A NOTHING
</code></pre>
<p>What I had in mind is to sort the values in an ascending order by ID1,ID2,ID3 and descending by FLAG. After that I could loop through the dataframe line by line, check if the FLAG is a P and store the 3 IDs and the DATA_FIELD value in a dictionary or something.
On the next line I need to check if the keys are the same, then if the conditions are True, then update the DATA_FIELD. Not sure however if this is the best solution:</p>
<pre><code>df.sort_values(["ID1", "ID2", "ID3", "FLAG"],
ascending=[True, True, True, False], inplace=True)
df.reset_index(drop=True, inplace=True)
parent_keys = None
for index, row in df.iterrows():
if row["FLAG"] == "P":
parent_keys = f"{row['ID1']}{row['ID2']}{row['ID3']}"
parent_data_field_value = row["DATA_FIELD"]
if row["FLAG"] == "C":
if parent_keys:
child_keys = f"{row['ID1']}{row['ID2']}{row['ID3']}"
if child_keys == parent_keys:
if row["CONDITION_1"] == 0 and row["CONDITION_2"] == "B":
df.loc[index, "DATA_FIELD"] = parent_data_field_value
</code></pre>

74,449,024 | <p>Right now I have two functions:</p>
<pre><code>public void func(Unity.Collections.NativeArray<ushort> a){}
public void func(Unity.Collections.NativeArray<short> a){}
</code></pre>
<p>The functions are the exact same besides the object datatype input. I am also not writing to these NativeArrays, so the code functions identically whether it is reading the array as <ushort> or <short>. Is there a way to combine these into one function that can accept both types of objects? NativeArrays are a managed type, so I can't use pointers. Any other ways to avoid duplicating the whole function or duplicating the objects?</p>

74,449,116 | <p>I’m having re-rendering issues, any help is greatly appreciated. I tried useMemo and useCallback and it broke the checkbox. I have a component, and inside that component, I display some info in my object. I have let's say an object as such:</p>
<pre><code>fakeObject = {
name: "rectangle"
width: 10
height: 20
visible: true
}
const fakeComponent = () => {
const [checked, setChecked] = React.useState(true);
const handleChange = (event: React.ChangeEvent<HTMLInputElement>) => {
setChecked(event.target.checked);
fakeObject["visible"] = event.target.checked;
};
return(
<div>
<h2> {fakeObject.name} </h2>
<p> The height is {fakeObject.height} </p>
<Checkbox
checked={checked}
onChange={handleChange}
inputProps={{ 'aria-label': 'controlled' }}
/>
</div>
)
};
</code></pre>
<p>The issue is that every time I click my checkbox it rerenders the whole component. This is a simplified version of my issue but I see that the component uses my fakeObject and that the checkbox changes that but how do I make it so that my whole component doesn't re-render? Thanks for any help</p>

74,449,178 | <p>I'm new to using axios and stripe and I'm encountering some issues. When I try to make a post request with axios I receive this error:</p>
<p><a href="https://i.stack.imgur.com/4rFrb.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/4rFrb.png" alt="This is the error I receive when making a post request" /></a></p>
<p>Perhaps my endpoint is incorrect. I'm not sure. Here is my code in Payments.js:</p>
<pre><code>
import React,{useState, useEffect} from 'react'
import CheckoutProduct from './CheckoutProduct';
import './Payment.css';
import {useStateValue} from './StateProvider';
import {Link, useHistory} from 'react-router-dom';
import {CardElement, useStripe, useElements} from "@stripe/react-stripe-js";
import CurrencyFormat from "react-currency-format";
import {getBasketTotal} from "./reducer";
import axios from './axios';
function Payment() {
const [{basket,user}, dispatch] = useStateValue();
const history = useHistory();
const stripe = useStripe();
const elements = useElements();
const [succeeded, setSucceeded] = useState(false);
const [processing, setProcessing] = useState("");
const [error,setError] = useState(null);
const [disabled,setDisabled] = useState(true);
const [clientSecret,setClientSecret] = useState(true);
useEffect(() => {
const getClientSecret = async () => {
try {
const response = await axios({
method: 'post',
url: `/payments/create?total=${getBasketTotal(basket)*100}`
});
console.log("THIS IS THE RESPONSE", response);
setClientSecret(response.data.clientSecret);
}
catch (error) {
console.log("THIS IS THE ERROR", error);
}
}
getClientSecret();
},[basket]);
console.log('THE CLIENT SECRET >>>', clientSecret);
</code></pre>
<p>And here is my middleware code in index.js:</p>
<pre><code>const functions = require("firebase-functions");
const express = require("express");
const cors = require("cors");
const stripe = require("stripe")("/* my secret stripe api key is here */");
const app = express();
app.use(cors({origin: true}));
app.use(express.json());
app.get("/", (request, response) => response.status(200).send
("hello world"));
app.post("/payments/create/", async (request, response) => {
const total = request.params.total;
console.log("Payment Request Received >>>", total);
const paymentIntent = await stripe.paymentIntents.create({
amount:total,
currency:"usd",
});
response.status(201).send({
clientSecret: paymentIntent.client_secret,
})
});
exports.api = functions.https.onRequest(app);
</code></pre>
<p>Here is my axios.js file:</p>
<pre><code>import axios from "axios";
const instance = axios.create({
baseURL: 'http://127.0.0.1:5001/clone-bfd8a/us-central1/api'
});
export default instance;
</code></pre>
<p>I was reviewing the post endpoint in my Payments.js file to see if it was correct. Then I checked my middleware in index.js to see if it coincided with my endpoint in Payment.js. To me, the endpoints seem correct. I was expecting that the application show the <code>clientSecret</code> but instead I got the axios Network Error.</p>
<p>I also received this error in my terminal:
<a href="https://i.stack.imgur.com/xFNDS.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/xFNDS.png" alt="It states that the 'amount' parameter is missing" /></a></p>
<p>It says the 'amount' parameter is missing but I'm not sure why it says that because I included it in the post middleware route.</p>
<p>I think the error may be in Payments.js where it says:</p>
<pre><code>setClientSecret(response.data.clientSecret);
</code></pre>
<p>Maybe <code>response.data.clientSecret</code> doesn't exist.</p>
<p>I'm also thinking the error is in index.js where it says:</p>
<pre><code>
clientSecret: paymentIntent.client_secret,
</code></pre>
<p>Perhaps <code>client_secret</code> is not defined by stripe. I'm not sure. Any ideas why I'm receiving this Axios network error? Any help is appreciated! Thanks in advance :)</p>
<p>UPDATE:</p>
<p>So it seems to be kind of working now. I changed <code>req.params.total</code> to <code>req.query.total</code> in my middleware post route in index.js:</p>
<p><a href="https://i.stack.imgur.com/umncH.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/umncH.png" alt="enter image description here" /></a></p>
<p>But it still seems to be acting kind of weird: When I first start the application, I get the error as mentioned above. However, after waiting a couple of minutes, I am able to successfully make a post request with axios. Is it possible that the frontend and backend need to take some time to be synchronized? Could it be that the error is happening because the <code>basket</code> variable is empty at first and then axios tries to make the post request? Thanks in advance!</p>

74,449,198 | <p>I'm trying to pass an array into a method. The idea is a random number is generated, <code>i</code>, and the value of <code>xArray[i]</code> is copied into <code>yArray[x]</code>, where <code>x = 0</code> is increased with each run.</p>
<p>What I don't understand is the array I pass into the method is modified as well. For example:</p>
<pre class="lang-rb prettyprint-override"><code># inputArray is populated by the capital letters of the alphabet, e.g. "A", "B", ... "Z"
def populateArray inputArray
xArray = inputArray
yArray = Array.new
i = 0
while yArray.length < 26
# Subtract i to take into account decreasing array size
x = rand(26-i)
yArray[i] = xArray[x]
# Delete entry so I don't get duplicate letters
xArray.delete_at(x)
i = i + 1
end
end
puts "inputArray length: #{inputArray.length.to_s}"
puts "xArray length: #{xArray.length.to_s}"
puts "yArray length: #{yArray.length.to_s}"
</code></pre>
<p>I can understand why xArray.length is 0, because that is the one I have been removed entries from. But why is it also affecting inputArray?</p>
<p>I have tried creating a copy by doing this: <code>xArray = inputArray</code>, but it doesn't seem to make a difference.</p>
<p>I'm expecting the inputArray to maintain its length, and have the values inside untouched.</p>
<p><strong>NOTE:</strong> <em>I am entirely new to Ruby, and have only covered the "Learn to Program" section recommended on the Ruby website. Any suggestions about formatting and easier ways to do things are always welcome.</em></p>

74,449,237 | <p>The question is asking to create a nested loop to append and increase multiple index in a 2D list,for somehow I can't print the element in the list and i tried to print the length of the list it just return 0.</p>
<p>the expect value in the list is:</p>
<p>If duration of the music sequence is 1s, starting pitch is 60 and ending pitch is 64, then the content of the music list for one sequence will be:</p>
<pre><code>[ [0.0, 60, 0.2],
[0.2, 61, 0.2],
[0.4, 62, 0.2],
[0.6, 63, 0.2],
[0.8, 64, 0.2] ]
</code></pre>
<p>There are 5 music notes because the pitch number starts from 60 and goes up to 64, i.e. number of notes = 64 - 60 + 1</p>
<p>The duration of each music note is 0.2s, which is just the duration of the music sequence divided by 5</p>
<p>so the list is</p>
<pre class="lang-py prettyprint-override"><code>music_data=[time,pitch,duration]
</code></pre>
<p>here are more examples
if the music sequence is repeated twice, an example music data with five notes (from 60 to 64 and a music sequence duration of 1 second) will look like this:</p>
<pre><code>[ [0.0, 60, 0.2],
[0.2, 61, 0.2],
[0.4, 62, 0.2],
[0.6, 63, 0.2],
[0.8, 64, 0.2],
[1.0, 60, 0.2],
[1.2, 61, 0.2],
[1.4, 62, 0.2],
[1.6, 63, 0.2],
[1.8, 64, 0.2] ]
</code></pre>
<p>You need to be careful that the range of pitch numbers works quite differently for increasing pitch numbers (step = 1) and decreasing pitch numbers (step = -1)
You also need to make sure that the range of pitch numbers is inclusive of the starting pitch and the ending pitch values</p>
<p>For example, if the starting pitch and ending pitch are 60 and 72 respectively, you will need write range(60, 73) to generate the correct range of pitch numbers</p>
<p>The function template provided by task:</p>
<pre class="lang-py prettyprint-override"><code># This function makes a piece of crazy music in the music list
def makeCrazyMusic():
global music_data
#####
#
# TODO:
# - Ask for the crazy music parameters
# - Clear the music list
# - Use a nested loop to generate the crazy music in the music list
# - Update the music summary
#
#####
</code></pre>
<p>After refer to the instruction, i ve tried :</p>
<pre class="lang-py prettyprint-override"><code>def makeCrazyMusic():

#
#####
#time = start time of note
#pitch the pitch of note
#durantion the length of the note
#duration = duration / note --constant
# = duration / startpitch -endpitch+1)
#note = start pitch - end pitch +1
#time = time + duration
#pitch = from start to end
#
try:
times_input = int(turtle.numinput("Times to play",\

except TypeError:

index= index+(dura_input/times_input)

</code></pre>
<p>The expected OUTPUT is:
if the music sequence is repeated twice, an example music data with five notes (from 60 to 64 and a music sequence duration of 1 second) will look like this:</p>

74,449,397 | <p>I have an object called headers. Inside which I want to add certain headers with some random value like:</p>
<pre class="lang-js prettyprint-override"><code>configs = {
header : {
'x-some-id': Math.random().toString()
}
}
</code></pre>
<p>The config paramter is used to client which is used to send http requests. And the randomid is some id generated by a load balancer. So it will we different for every request. We dont want to create a new client for every client, hence I want to use getter function in header so that everytime a request is made, the header is automatically populated with a new id. How do I implement this using getters. ideally this is what I what to achieve:</p>
<pre class="lang-js prettyprint-override"><code>configs = {
header : {
'x-some-id': get() { return Math.random().toString()}
}
}

74,449,462 | <p>Let's say we have a class that has a function foo() that counts to 3 and we want from another class to be able to modify this function and after modifying it counts to 3 that was previously declared but also executes the new code too. The function foo() would only be called by class1 and i dont want to use inheritance. The new code that im supposed to add lets say it doesnt have any relationship with class1.</p>
<p>For Example:</p>
<pre class="lang-cpp prettyprint-override"><code>#include <iostream>
using namespace std;
class class1 {
public:
class1()
{
}
void foo()
{
for(int i =0;i<2;i++)
{cout << i << endl;}
}
};
class class2 {
public:
class2()
{
}
void foo() override
{
Super::foo();
cout << "Jump from a cliff" << endl;
}
};
int main()
{
class1 c1 = class1();
class2 c2 = class2();
c1.foo();
return 0;
}
</code></pre>
<p>Result:</p>
<pre><code>0
1
2
Jump From a cliff
</code></pre>

74,449,475 | <p>I have a dataset that looks like that:</p>
<p><a href="https://i.stack.imgur.com/lFczO.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/lFczO.png" alt="enter image description here" /></a></p>
<p>There are 15 unique values in the column 'query id', so I am trying to create new dataframes for each unique value. I thought of having a loop for every unique value in column 'query id' with a code like this:</p>
<pre><code>df_list = []
i = 0
for x in df['query id'].unique():
df{i} = pd.DataFrame(columns=df.columns)
df_list.append()
i+=1
</code></pre>
<p>But I am definitely doing something wrong there and got stuck. Do you have any ideas of how to do that?</p>
<p>Sample dataset:</p>
<pre><code>relevance query id 1 2 3
1 WT04-170 10 40 80
1 WT04-170 20 60 70
1 WT04-176 30 70 50
1 WT04-176 40 90 20
1 WT04-173 50 100 10

74,449,478 | <p>I read that <code>stdint.h</code> is used for portability, but I'm confused.</p>
<p>If I wrote a program on a 32-bit system, uint32_t (unsigned int) is 4-bytes.</p>
<p>But when this program is run on 16-bit system, int is 2bytes and uint32_t (unsigned int) is 2bytes.</p>
<p>I think portability is not guaranteed in this case.
Is there anything I am understanding wrong?</p>

74,449,510 | <p>I have a question to make the environment of <code>if true then x else y</code> not closed, closed but not well typed, and closed and well typed. How can I do this in OCaml?</p>
<p>All I know is that not closed means that there is a variable that is not bound. So x and y will not be bound in this case. Additionally, well typed means that the expression satisfies the grammar.</p>
<p>Im not sure how to apply that here however and I only have very wrong answers. Maybe something like:</p>
<pre><code>if (x:int, y:int) then (true) else (false)
if (x:int, y: int) then (x: bool) else (y: bool)
if (true) then (x: int) else (y: int)
</code></pre>
<p>for the 3 conditional respectively</p>

74,449,523 | <p>I have a number of checkboxes that return an array of data to PHP. They are all named 'Plans[]' but with different IDs.</p>
<p>I have a CSS checkbox styler that replaces the usual HTML checkbox with something more fancy...</p>
<p>When the page is displayed, there is one (or several) that are 'checked', but they don't display as checked (I think one does but that is hidden usually).</p>
<p>I am assuming that the problem is caused by them all having the same name and so somehow they are the checked attribute is not getting acted on for all of them for this reason.
I have tried wrapping each of them in their own forms (as I saw this suggested elsewhere) but to no avail.</p>
<p>Here's an example of what it looks like:</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-html lang-html prettyprint-override"><code><style type="text/css">

}
.checkOpt input:disabled ~ .checkmark {
background-color:#b0c7df; pointer:default;
}

}
</style>
<div class="test">
<div class="checkOpt" style="top:20px;">

<span class="checkmark"></span>
</label>
</div>
</div></code></pre>
</div>
</div>
</p>
<p>...only one of these (the first) is showing as checked - the rest are not.
Does anyone have any ideas what I might do to get round this (without coding changes to the subsequent data collection if possible!)</p>
<p>tried everything I can think of and would welcome any suggestions....</p>
<p>UPDATE - I tried updating the page so that the checkboxes have different names ('Plans[0]', 'Plans[1]' etc.) and the checkmarks suddenly started to appear in the right places.</p>
<p>The issue is now that there is (legacy) JQuery code that doesn't work, i.e.</p>
<pre><code>$("input[name='plans[]']:checked").each(function(){
var thisPlan= $(this).attr('id'); var thisVal = $(this).attr('value');
plans.push(thisPlan);
planValues.push(thisVal);
// ....
// ....
}
</code></pre>
<p>I guess this would work if the Plans list were just POSTed and picked up by PHP, but in fact it is intercepted by Javascript, processed and re-posted via Ajax to the next (PHP) page (where it is picked up quite simply by $_POST['plans']). It's a real mess, but Ihave inherited it...</p>
<p>Anyone have any idea how I could work round this without breaking all the legacy (Javascript/JQuery) code?</p>

74,449,533 | <p>I've decided to write a custom AuthorizationHandler for a custom Policy I'm using :</p>

context.Fail();

<p><strong>Problem : this doesn't seem to generate a "valid" 404 response.</strong>
I think so for two reasons:</p>
<ul>
<li>When I look at Chrome's network tab, the response is NOT "404", instead it's <strong>net::ERR_HTTP2_PROTOCOL_ERROR 404</strong></li>
<li>When I look at the response data, there's only headers. <strong>My custom error text ("Blah blah NotFound") does not appear anywhere.</strong></li>
</ul>
<p>What am I doing wrong?</p>
<p><em>Note : I've tried returning immediately after setting the 404, without doing context.Fail() but I get the same result.</em></p>

74,449,538 | <p>On running the following MySQL (5.7.12) UPDATE statement, I get the error <em>"Error Code: 1054. Unknown column 't1.col2' in 'where clause'"</em>.</p>
<p>How can I rephrase this query such that the columns of t1 are accessible in the subquery?</p>
<pre><code>UPDATE MyFirstTable AS t1
INNER JOIN (
SELECT col1, col2
FROM MySecondTable
WHERE col2 > t1.col2
) AS t2
ON t1.col1 = t2.col1
INNER JOIN (
SELECT col1, col2
FROM MySecondTable
WHERE col2 < t1.col2
) AS t3
ON t1.col1 = t3.col1 AND t3.col2 = t2.col2
SET t2.col3 = t1.col3;
</code></pre>
<p>The objective here is to update MyFirstTable with rows from MySecondTable where, for a given col1 value, col2 was both less than and more than t1.col2 (on different rows, of course).</p>

74,449,578 | <p>I wonder if we can extend the logic of <a href="https://stackoverflow.com/questions/35584085/how-to-count-duplicate-rows-in-pandas-dataframe">How to count duplicate rows in pandas dataframe?</a>, so that we also consider rows which have similar values on the columns with other rows, but the values are unordered.</p>
<p>Imagine a dataframe like this:</p>
<pre><code> fruit1 fruit2
0 apple banana
1 cherry orange
3 apple banana
4 banana apple
</code></pre>
<p>we want to produce an output like this:</p>
<pre><code> fruit1 fruit2 occurences
0 apple banana 3
1 cherry orange 1
</code></pre>
<p>Is this possible?</p>

74,449,591 | <p>I've got everything working correctly except this one problem - with the third output it says the max pair sum is 13 due to taking sum of the first and last number. It should be 11 (as 9+2 or 4+7). I can't figure it out how I fix this problem - ending the loop with the first and last position.</p>
<p>Thank you for all advice.</p>
<pre><code>def _sum(num_list):
maxSum = -9999999
for i in range(len(num_list)):
for j in range(i-1, i+1):
if not num_list[i] == num_list[j]:
maxSum = max(maxSum, num_list[i] + num_list[j])
return maxSum
print(_sum([1, 8, 7, 3, 5, 2]))
# correct answer: 15
print(_sum([1, 2, 45, 4, 5, 6, 7, 3, 2]))
# correct answer: 49
print(_sum([9, 2, 3, 4, 7, 1, 2, 3, 4]))
# correct answer: 11
</code></pre>
<p>I have tried write some if conditions into for j loop but it ended up with many errors. I'm truly out of ideas and I can't even imagine how it could be right.</p>

74,449,599 | <p>So i was working on some python code so i could get a better understanding of dictionaries. I have only been learning python 2 weeks and its my first language, so there is definitely a lack of knowledge on my end. I started the program originally to have a user input the section number they were on in a video series and it would output how much time they have left in the entire series. I think expanded on the code to add more output of things like % complete, etc. One of the outputs I added last to the program is to take the section that the user had entered as input and display how long that section is. There are 23 total sections and if the users enters 1-14 then it displays the information accurately. However, if they enter 15-23 then that display line is completely ignored on output. I won't post the whole code as its too long, but here is some of the relevant info.</p>
<p>Here is the dictionary at the top of the code. The key is the section and the value is the number of minutes in that section. Then you have the only input in the program, followed by the code for showing the length of the selected section.</p>
<pre><code>video_dict = {
1 : 19, 2 : 54, 3 : 122, 4 : 9, 5 : 75, 6 : 174, 7 : 100, 8 : 81, 9 : 29, 10 : 46, 11 : 138, 12 : 23, 13 : 17, 14 : 143, 15 : 143,
16 : 24, 17 : 45, 18 : 28, 19 : 3, 20 : 41, 21 : 45, 22 : 15, 23 : 1
}
current_section = int(input('What section are you currently on? (1-23)\n'))
# Show how long the selected section is
current_total_time = int(video_dict[current_section])
current_total_minutes = 0
current_total_hours = 0
if current_total_time >= 60:
current_total_minutes = int(current_total_time % 60)
current_total_hours = int((current_total_time - current_total_minutes) / 60)
if current_total_hours == 1:
if current_total_minutes == 1:
print(f'Section {current_section} is {current_total_hours} hour and {current_total_minutes} minute long.\n')
elif current_total_minutes >= 2:
print(f'Section {current_section} is {current_total_hours} hour and {current_total_minutes} minutes long.\n')
elif current_total_minutes == 0:
print(f'Section {current_section} is {current_total_hours} hour long.\n')
elif current_total_hours >= 2:
if current_total_minutes == 1:
print(f'Section {current_section} is {current_total_hours} hours and {current_total_minutes} minute long.\n')
elif current_total_minutes >= 2:
print(f'Section {current_section} is {current_total_hours} hours and {current_total_minutes} minutes long.\n')
elif current_total_minutes == 0:
print(f'Section {current_section} is {current_total_hours} hours long.\n')
elif (current_total_time > 0) and (current_total_time < 60):
if current_total_minutes == 1:
print(f'Section {current_section} is {current_total_minutes} minute long.\n')
elif current_total_minutes >= 2:
print(f'Section {current_section} is {current_total_minutes} minutes long.\n')
</code></pre>
<p>As a side note, I know this code is probably a little too verbose but at my current stage in learning this is where i'm at. Would there be a shorter way to type this code so that I could clean it up a little? You don't have to type an example, unless you want to, you can just say what commands i should be looking at in python and learning to accomplish this. Thank you for your input.</p>

74,449,630 | <p>My question is similar to <a href="https://stackoverflow.com/questions/13744620/create-a-matrix-out-of-row-column-value-triplets-in-numpy">this one</a>, but still different.
I have a list of triplets like the following, representing rows and columns of a matrix with their cell value:</p>
<pre><code>a = [("g1","g2",7),("g1","g3",5)]
</code></pre>
<p>The matrix is symmetrical, so the elements can be provided in any order - meaning that <code>("g1","g2",7)</code> would imply <code>("g2","g1",7)</code>.</p>
<p>I would like to obtain a pandas df from this list, representing a matrix that has element names on the rows and columns, with missing values if a triplet is not listed in <code>a</code>:</p>
<pre><code> g1 g2 g3
g1 NaN 7 5
g2 7 NaN Nan
g3 5 NaN Nan
</code></pre>
<p>can you help me achieve this task in the most efficient way for huge lists?</p>
