74,427,502 | <p>I would like to take the json output of window values from a program. The output of it currently is:</p>
<pre><code>[
3067,
584
]
[
764,
487

</code></pre>
<p>But I need it to be formatted like: <code>3067,584 764x487</code>. How would I go about doing this using jq or other commands?</p>
<p>I'm not very experienced with jq and json formatting in general, so I'm not really sure where to start. I have tried looking this up but am still not really sure how to do it.</p>

74,427,520 | <p>I'm doing a GET fetch request to my DB on page load and wish to display only the True items.</p>
<p>The response json object has 32 items returned from the API.
They are all key value pairs (with boolean values) eg:</p>
<pre><code>{
Apple: false
Banana: false
Orange: true
Kiwi: true
}
</code></pre>
<p>I need to find ONLY the true items, create a button element for each true item, set the button text label from the Key, and add this to my page inside an empty div.</p>
<p>I've played with If/Else and turning the Object into an Array with Object.entries - but I'm out of my depth and don't really know the right approach.</p>
<p>Any help appreciated.
Cheers</p>
<p>(Vanilla JS only thx)</p>

74,427,563 | <p>MySQL will accept NULL to an <code>auto increment</code> column and insert the last value. So you could presumably use</p>
<p>(Using the code from <a href="https://stackoverflow.com/a/46805508/631764">this SO answer</a>, where <code>st</code> is a <code>preparedStatement</code>)</p>
<p><code>st.setNull(1, java.sql.Types.NULL)</code></p>
<p>I'm trying to figure out how you do the same with Postgresql, where you cannot use <code>NULL</code>, but must use <code>DEFAULT</code> instead:</p>
<pre><code>INSERT INTO serial_table (id) VALUES(NULL)
</code></pre>
<p>Does something like this exist?</p>
<pre><code>st.setDefault(1, java.sql.Types.DEFAULT)
</code></pre>
<p>Or</p>
<pre><code>st.setObject(1, "DEFAULT")
</code></pre>
<p>I assume I can't just use the string "DEFAULT".</p>
<p>EDIT:</p>
<p>To clarify, this is a testing table defined as such:</p>
<pre><code>CREATE TABLE serial_table (
id SERIAL NOT NULL PRIMARY KEY
);
</code></pre>
<p>So I can't just skip the column to let Postgresql handle it</p>
<pre><code>INSERT INTO serial_table VALUES()
ERROR: syntax error at or near ")"
LINE 1: INSERT INTO serial_table VALUES();
^
</code></pre>

74,427,661 | <p>Here I'm developing a service which is going to receive a SOAP request Message and then convert it into JSON. After that, I want to invoke a REST API with the converted JSON and then I want to receive the JSON response back from that REST API and finally I want to convert that JSON response into SOAP Response message and then send it back the caller service. So basically this service is going to act as a intermediate Wrapper service between SOAP and REST communication.</p>
<p>I've the WSDL with me and need a way to do this by using Spring boot. Could any help me here please?</p>
<p>Currently I'm doing as below -</p>
<pre><code>@RestController
public class WrapperController {
@PostMapping(
value = "/wrap",
consumes = MediaType.APPLICATION_XML_VALUE,
produces = MediaType.APPLICATION_JSON_VALUE)
public Q248Req wrapSOAPRequest(@RequestBody String SOAPReq)
throws SOAPException, IOException, JAXBException {
System.out.println("SOAP Request: " + SOAPReq);
SOAPMessage message =
MessageFactory.newInstance()
.createMessage(null, new ByteArrayInputStream(SOAPReq.getBytes()));
Unmarshaller unmarshaller = JAXBContext.newInstance(TestObj.class).createUnmarshaller();
TestObj Req =
(TestObj) unmarshaller.unmarshal(message.getSOAPBody().extractContentAsDocument());
return Req;
}
</code></pre>
<p>I have generated the TestObj class from the supplied WSDL then I'm trying to map SOAP Message to TestObj class but it's throwing error -</p>

74,427,701 | <p>I use <code>EditForm</code> in the Blazor Server. The <code>EditForm</code> has a property named <code>OnValidSubmit</code>.<br />
Suppose that I have used the <code>Required</code> attribute on a field in the model such as:</p>
<pre><code> [Required]
public string Name { get; set; }
</code></pre>
<p>If the user disables JavaScript in the browser, is server-side validation also performed by <code>OnValidSubmit</code>?</p>
<p>There is the <code>ModelState.IsValid</code> In the asp.net <code>mvc</code>, Is there an alternative in Blazor? Considering the use of <code>OnValidSubmit</code>, is it really necessary to manually check the model validation again on the server side?</p>

74,427,747 | <p>I am trying to convert a CSV into a dataframe and also updating column values in the CSV. But the issue I am facing is I am not getting rid of the index column as a result I am getting an extra index column without name in the console as follows.</p>
<pre><code> fsym_id factset_entity_id ... is_substituted is_current
0 VVG1JM-S ABCXYZ-Z ... True False
</code></pre>
<p>If you see below, there is no column name for 0. If I try dropping first column in the dataframe using the following code line, <code>df.drop(columns = df.columns[0], axis = 1, inplace= True)</code>, it drops the fsym_id column which I need. Below is the code.</p>
<pre><code>def update_run_id_in_csv(rds_db_conn,test_case_name,file_name):
df = pd.read_csv("{}/output/Float_Ingestion_Expected_Output_files/{}/{}.csv".format(str(parentDir), test_case_name, file_name))
df['run_id'] = '2323323232999'
#get_run_id(rds_db_conn,max_13f_query,query)
df.drop(columns = df.columns[0], axis = 1, inplace= True)
print(df)
</code></pre>
<p>There is no index column in the CSV. I am not able to understand how it gets added while updating the column run id in the data frame. How to get rid of the index column?</p>

74,427,881 | <p>Hi I want to know how can i do this query in Laravel 8 , I tried adding the join clause but not work as expected, i need join clause? Or maybe there is another form to do it. I search others examples but i don´t see anythat help me. The query is the next:</p>
<pre><code>DB::table('escandallo_p as esc')
->select("esc.material", "esc.referencia", "esc.ancho", "esc.proveedor", "esc.punto",

DB::raw("(select anulado from prototipos_p as p where p.prototipo = '".$scandal[0]->prototipo."' and p.tipo = 'c' and p.referencia = esc.referencia )"),
// ignore
//original query "(select anulado from prototipos_p as p where p.prototipo = ",$request->prototipo," and p.tipo = 'c' and p.referencia = esc.referencia ) as 'anulado'",
// "(select clase from prototipos_p as p where p.prototipo = ",$request->prototipo," and p.tipo = 'c' and p.referencia = esc.referencia ) as 'clase'")
//Converted query ->select('pro.anulado')->where('pro.prototipo', $request->prototipo)
// ->where("p.prototipo", "=", $request->prototipo)
->where("esc.id_escandallo", "=", $request->id_escandallo)
->where("esc.id_version", "=", $request->version)
->orderBy("id","asc")
->get();
</code></pre>
<p>!!!! I need to pass the esc.referencia to the sub select query</p>
<p>The second select is the conversion of the select inside "" ( i know this is wrong is only for explain it).</p>
<p>Thank you in advance for any suggestion.</p>
<p>Best regards</p>
<p>EDIT: I can solve my problem with DB::raw, but if anyone know others methos are welcome!</p>

74,427,883 | <p>I have a column that contains either letters or numbers. I want to add a column identifying whether each cell contains a letter or a number. The problem is that there are thousands of records in this particular database.</p>
<p>I tried the following syntax:</p>
<p><code>= Table.AddColumn(Source, "Column2", each if [Column1] is number then "Number" else "Letters")</code></p>
<p>My problem is that when I enter this, it returns everything as "Letter" because it looks at the column type instead of the actual value in the cell. This remains the case even when I change the column type from Text to General. Either way, it still produces "Letter" as it automatically assigns text as the data type since the column contains both text and numbers.</p>

<ul>
<li><p>This is different from finding smallest element in sorted matrix, which is log(n)+log(n) or 2log(n).</p>

I think <code>LayoutBuilder()</code> doesn't work appropriately.

74,428,043 | <p>I am unable to register an user from my app written in Flutter. I am also unable to get some form for error message. I can debug and see my createUser function is called and the arguments looks good. Nothing happens after I call "FirebaseAuth.instance.createUserWithEmailAndPassword". No exception and nothing is printed in the FireBase emulator console. What am I missing here? Here is what I got:</p>
<pre><code>Emulator:
Running on 127.0.0.1:9099
</code></pre>
<p>main.dart:</p>
<pre><code>void main() async {
WidgetsFlutterBinding.ensureInitialized();
await Firebase.initializeApp(options: DefaultFirebaseOptions.currentPlatform,);
try {
await FirebaseAuth.instance.useAuthEmulator('localhost', 9099);
} catch (e) {
// ignore: avoid_print
print(e);
}
runApp(
MaterialApp(
title: "Foo",
home: buildContent(),
),
);
}
</code></pre>
<p>Registration function:</p>
<pre><code>void createUser() async {
print("createUser()");
try {
final credential = await FirebaseAuth.instance.createUserWithEmailAndPassword(
email: nameController.text,
password: passwordController.text,
);
//final credential = await FirebaseAuth.instance.createUserWithEmailAndPassword(email: nameController.text, password: passwordController.text);
} on FirebaseAuthException catch (e) {
if (e.code == 'weak-password') {
print('The password provided is too weak.');
} else if (e.code == 'email-already-in-use') {
print('The account already exists for that email.');
}
} catch (e) {
print(e);
}
}
</code></pre>
<p>Edit:
I keep getting this message when i call "createUserWithEmailAndPassword"</p>
<p>W/System (26859): Ignoring header X-Firebase-Locale because its value was null.</p>

74,428,048 | <p>I have a react application where I pass state via react router and access the state using location in the target component/page. It works perfect, however when I close the tab and paste the exact same url to that page in another tab it crashes and says <code>Cannot read properties of null (reading '1')</code>. This is how I am accessing the state:</p>
<pre><code>const { filter, mode } = location?.state[1];
</code></pre>
<p>I want to navigate to home page if the location state is null.</p>
<p>I have tried the following but does not seem to work.</p>
<pre><code>if (location.state === null) {
navigate("/");

const { filter, mode } = location?.state[1];

</code></pre>
<p>As you can see, it will check if the password is not empty and it's length is more than <code>12</code> characters, then go ahead and check for <code>e.match(format1)</code>.</p>
<p>But the problem is, when I enter those characters as well, it will not return this condition as true and therefore the message <strong><code>strong</code></strong> does not appear and still shows <strong><code>normal</code></strong> message on screen.</p>
<p>So what's going wrong with this?</p>
<p>How can I solve this problem and properly check if the string contains the written symbols or not?</p>

74,428,166 | <p>I have this pretty straightforward formula in my <a href="https://docs.google.com/spreadsheets/d/1vMbnxv-Oz5hzEowZvjrc1KVWwI1q0N03cs-z9Zs5lBE/edit#gid=0" rel="nofollow noreferrer">Spreadsheet</a>:</p>
<blockquote>
<p>={"Number of purchases"; SUM(C3:C) ; ARRAYFORMULA(if(isblank(A3:A),,sumif('Raw Data'!A:A,A3:A,'Raw
Data'!B:B)+sumif('Raw Data'!A:A,B3:B,'Raw Data'!B:B)))}</p>
</blockquote>
<p>The issue is when I apply a filter to row 1, my SUM will be messed up if I sort the data.
I would like my filter to remain in row 1 and not to row 2.</p>
<p>Any solution/help would be appreciated.</p>

74,428,175 | <p>I have a JSON array where I need to get the CustomerId value from property where the CustomerId property exits for that section, I'm trying below to loop through the categories and skip the one that has no CustomerId property down its properties tree</p>
<pre><code>var customerId = "";
foreach (var category in JObject.Parse(someData)?["categories"])
{
val = category?["sections"].FirstOrDefault()
?["areas"]?.FirstOrDefault()
?["components"]?.
?["variables"]?.FirstOrDefault()
?["properties"]
?["customerId"]?.ToString();
if (val == null)
continue;
else
{
customerId = val;
break;
}
}
</code></pre>
<p>Problem is this looks inefficient (less readable) in the sense that I imagine there is a nice <code>.Select</code> that can be used to get the same result without going forEach element and check if the property is null.</p>
<p>Please not this is not an issue I have, this is working, I'd only like to do this in a more readable way using <code>Select</code> instead of <code>ForEach</code>.</p>

I want to run this Maven project in my Docker container so that i can move files on my Windows via Docker.</p>
<p>When i tried doing it, it gave no error but there was no copy process either. Can i manage files on my host machine with Docker?</p>

As the writer claimed, the structure of MHA (by the original paper) is as follows:</p>
<p><a href="https://i.stack.imgur.com/hwDQq.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/hwDQq.png" alt="enter image description here" /></a></p>
<p>But the <a href="https://www.tensorflow.org/api_docs/python/tf/keras/layers/MultiHeadAttention" rel="nofollow noreferrer"><code>MultiHeadAttention</code></a> layer of Tensorflow seems to be more flexible:</p>
<ol>
<li>It does not require <code>key_dim * num_heads = embed_dim</code>. Like:</li>
</ol>
<pre><code>layer = tf.keras.layers.MultiHeadAttention(num_heads = 2, key_dim = 4)
x = tf.keras.Input(shape=[3, 5])
layer(x, x)
# no error
</code></pre>
<p>Does the depth of the weight matrix in <code>tf.MHA</code> layer set to <code>key_dim * num_heads</code> regardless of <code>embed_dim</code>? So that Q/K/V can still be properly split by <code>num_heads</code>.</p>
<ol start="2">
<li>However, the output depth of tf.MHA layer is (by default) guaranteed to be <code>embed_dim</code>. So there is a final dense layer with <code>embed_dim</code> nodes to ensure the dimension？</li>
</ol>

74,428,449 | <p>I'm trying to add this feature called booking for others. If the user want to order 5 tour package, user have to input 4 emails of that user friends, to notify them that they got the tour package by this user. The idea i had is to store the emails in array. When i tried to create the front-end i got error <code>count(): Argument #1 ($value) must be of type Countable|array, null given</code>. How can i store the array value??</p>
<p>The Controller :</p>
<pre><code>public function store(Request $request){
$numbers = $request->numbers;
$emails = $request->email;
for($count = 0; $count < count($numbers); $count++){
emails::create([
'email'=>$emails[$count]
]);
}
return redirect ('/home/');
}
</code></pre>
<p>The blade file :</p>
<pre><code><form action="{{route('EmailStore')}}" method="post">
@csrf
<div class="form-group">
<label>How many people</label>
<input type="text" required class="form-control @error ('numbers') is-invalid @enderror"
id="numbers" name="numbers" autocomplete="off">
</div>
@php
$emails = count($numbers);
@endphp
@for ($i = 0; $i < $emails; $i++)
<tr>
<td>
<label>Email.{{$i}}</label>
<input type="text" required class="form-control @error ('email') is-invalid @enderror"
id="email" name="email[]" autocomplete="off">
</td>
</tr>
@endfor
<button type="submit" class="btn btn-info" id="btn_submit"
style="background-color: #eefa69; border:none; color:black">Submit</button>
</form>
</code></pre>
<p>For example input is like this :
<code>How many book : 5</code></p>
<pre><code>Email number 1 : a@gmail.com
Email number 2 : b@gmail.com
Email number 3: c@gmail.com
Email number 4: d@gmail.com

74,428,459 | <p>I’m creating demonstration code for a presentation.</p>
<pre><code>var fruitList = ["apple", "banana", "cherry", "durian", "elderberry", "fig", "grape", "huckleberry", "incaberry", "juniper", "kapok", "lime", "mango", "nectarine", "olive", "plum", "quince", "rambutan", "strawberry", "tangerine", "ugli", "vanilla", "watermelon", "xigua", "yarrow", "zhe"];
for (var i = 0; i < fruitList.length; i++) {
if (fruitList[i].charAt(fruitList[i].length-1) == "y") {
fruitList.splice(i, 1);
}
}
console.log(fruitList);
</code></pre>
<p>This code is working almost perfectly, but there’s one strange problem: the incaberry. No matter how many times I rename it, or put another element before or after it, it never gets removed from the list.</p>
<p>I tried to introduce new elements to the list, hoping to discover it was some strange problem with indexing, but it still stayed in the list.</p>
<p>Through experimentation, I learned that for any set of consecutive elements ending in y, only the first will be removed. How do I fix this?</p>

74,428,469 | <p>Hi currently in making new model I have some memory struggling.
I am doing summation between outputs of previous layers.
But it takes so much computation because it keeps allocating new memories I think.</p>
<p>print(max2.shape) = (None,8,8,96)</p>
<pre><code>...
c6 = layers.DepthwiseConv2D(kernel_size = (3,3), depth_multiplier = 1, padding = 'same', activation = 'relu')(max2)
c7 = layers.DepthwiseConv2D(kernel_size = (3,3), depth_multiplier = 1, padding = 'same', activation = 'relu')(max2)
# Concat All the Depthwised outputs
layer3_output_list = [c0,c1,c2,c3,c4,c5,c6,c7]
layer3 = layers.Concatenate(axis = -1)(layer3_output_list)
# Add R's G's B's
add_list = []
for i in range(layer3.shape[3]):
if i%6 == 0:
x = layers.Add()([layer3[:, :, :, i:i+1],layer3[:, :, :, i+3:i+4]])
y = layers.Add()([layer3[:, :, :, i+1:i+2],layer3[:, :, :, i+4:i+5]])
z = layers.Add()([layer3[:, :, :, i+2:i+3],layer3[:, :, :, i+5:i+6]])
add_list.append(x)
add_list.append(y)
add_list.append(z)
layer3 = layers.Concatenate(axis = -1)(add_list)
</code></pre>
<p>print(layer3.shape) = (None,8,8,768)</p>
<pre><code>max3 = layers.MaxPooling2D(pool_size = (2,2))(layer3)
flatten = layers.Flatten()(max3)
</code></pre>
<p>is there any way to make this use less memory?
Do I have to make customized Layer for this?</p>
<p><strong>In Addition</strong>
To explain about the for loops, with the result of layer3, I want to do sum between certain outcome "(ADD([layer3, layer3])" and add there Channels</p>
<p><strong>Currently</strong>
I'm doing summation between (ith, i+3th) and (i+1th, i+4th) and (i+2th, i+5th) but I think I will change how i do summation later on</p>

74,428,545 | <p>I'm writing my own <code>UICollectionViewLayout</code> subclass to have full control over the layout and arrangement of my collection view cells. When computing the item sizes, I want the layout to start with the cells' fitting sizes, i.e. I want the cells to size themselves to fit their content initially and then modify their frames later based on that information.</p>
<p>To get the fitting sizes, I first ask the collection view's data source for all cells in the layout's <code>prepare()</code> method and layout all the cells using <code>systemLayoutSizeFitting(_:)</code>.</p>
<pre><code>let allCells = allIndedxPaths.compactMap {
collectionView.dataSource?.collectionView(collectionView, cellForItemAt: $0)
}
let allItemSizes = allCells.map { cell in
cell.systemLayoutSizeFitting(.init(width: contentSize.width, height: UIView.noIntrinsicMetric))
}
</code></pre>
<p>Visually, everything works as expected and I get exactly the result I want. However, every time the collection view is laid out, the following warning it printed to the console:</p>
<blockquote>
<p>[CollectionView] An attempt to prepare a layout while a prepareLayout call was already in progress (i.e. reentrant call) has been ignored. Please file a bug.</p>
</blockquote>
<p>So it appears to me that it is prohibited to call any data source method while the layout is being prepared.</p>
<p>Which brings me to my question:</p>
<h4>How can I obtain information from the data source that I need to compute the layout from within my <code>UICollectionViewLayout</code> subclass?</h4>
<p>(Or more specifically: How can I get the concrete cell sizes right before I compute the layout?)</p>
<hr />
<h3>Notes:</h3>
<ol>
<li><p>Since Apple's own <code>UICollectionViewFlowLayout</code> works with automatic cells sizes (<code>estimatedItemSize</code>), there must be a clean way to get this information.</p>
</li>
<li><p>Apple's <em><a href="https://developer.apple.com/library/archive/documentation/WindowsViews/Conceptual/CollectionViewPGforIOS/CreatingCustomLayouts/CreatingCustomLayouts.html#//apple_ref/doc/uid/TP40012334-CH5-SW4" rel="nofollow noreferrer">Collection View Programming Guide</a></em> states:</p>
<blockquote>
<p>In a limited number of cases, the layout object might rely on information in the data source to position items. For example, a layout that displays items on a map might retrieve the map location of each item from the data source.</p>
</blockquote>
<p>This also means that there must be a way to query the data source from the layout object.</p>
</li>
</ol>
<hr />
<h3>Supplemental: Minimal Code Example</h3>
<p>Below is a (not so) minimal code for the layout that I'm trying to achieve.</p>
<pre><code>class SelfSizingTagListLayout: UICollectionViewLayout {
private var contentSize: CGSize = .zero
private var frames: [IndexPath: CGRect] = [:]
private var cachedAttributes: [IndexPath: UICollectionViewLayoutAttributes] = [:]
let interItemSpacing: CGFloat = 8
override func prepare() {
guard let collectionView else {
return
}
contentSize = .init(width: collectionView.bounds.width, height: 0)
let itemCount = collectionView.numberOfItems(inSection: 0)
let allIndedxPaths = (0..<itemCount).map { IndexPath(item: $0, section: 0) }
let allCells = allIndedxPaths.compactMap {
collectionView.dataSource?.collectionView(collectionView, cellForItemAt: $0)
}
let allItemSizes = allCells.map { cell in
cell.systemLayoutSizeFitting(.init(width: contentSize.width, height: UIView.noIntrinsicMetric))
}
frames = computeFrames(for: allItemSizes)
cachedAttributes = [:]
for frame in frames {
let attributes = UICollectionViewLayoutAttributes(forCellWith: frame.key)
attributes.frame = frame.value
cachedAttributes[frame.key] = attributes
}
contentSize.height = frames.map(\.value.maxY).max() ?? 0
}
private func computeFrames(for itemSizes: [CGSize]) -> [IndexPath: CGRect] {
let contentWidth = collectionView!.bounds.width
let rowHeight = itemSizes.map(\.height).max() ?? 0
var row: Int = 0
var x: CGFloat = 0
var y: CGFloat {
CGFloat(row) * (rowHeight + interItemSpacing)
}
var item: Int = 0
var frames: [IndexPath: CGRect] = [:]
for itemSize in itemSizes {
if x + itemSize.width > contentWidth {
row += 1
x = 0
}
let frame = CGRect(origin: .init(x: x, y: y), size: itemSize)
frames[IndexPath(item: item, section: 0)] = frame
item += 1
x += itemSize.width + interItemSpacing
}
return frames
}
override func layoutAttributesForElements(in rect: CGRect) -> [UICollectionViewLayoutAttributes]? {
cachedAttributes.map(\.value)
}
override func layoutAttributesForItem(at indexPath: IndexPath) -> UICollectionViewLayoutAttributes? {
cachedAttributes[indexPath]
}
override var collectionViewContentSize: CGSize {
contentSize
}
}

74,428,563 | <p>I have a <code>Text</code> tag in <code>expo/react-native</code> which i use on a screen to show live time using JavaScript <code>new Date()</code> object. Its giving me 24 hour format even when i set <code>"en-US"</code> and <code>hour12: true</code> i have tried everything but it doesn't seem to work.</p>
<p>Here is my code:</p>
<pre><code>const [liveTime, setLiveTime] = useState(new Date())
const refreshLiveTime = () => {
setLiveTime(new Date())
}
useEffect(() => {
const timerId = setInterval(refreshLiveTime, 1000)
return function cleanup() {
clearInterval(timerId)
}
}, [])
</code></pre>
<p>And here is how i render it in <code>Text</code> tag:</p>
<pre><code><Text>{liveTime.toLocaleTimeString("en-US", {hour12: true})}</Text>
</code></pre>
<p>Sample Expected output:</p>
<pre><code>01:12:18
</code></pre>
<p>Output i am receiving:</p>
<pre><code>13:12:18
</code></pre>
<p><strong>EDIT:</strong></p>
<p>I tried the same code in <code>reactjs</code> and it works fine there, i think the problem is with <code>react-native</code> here, maybe react-native doesn't support <code>toLocaleTimeString()</code></p>

74,428,674 | <p>I am still pretty new to iOS development. I have a (very?) large view that is causing a memory error. My <code>body</code> var looks something like this:</p>

HStack {

// many more views
}

<p><code>Thread 1: EXC_BAD_ACCESS (code=2, address=0x16cd27fc8)</code></p>
<p>The address seems to be different each time but always starts with 0x16, which leads me to believe it's a stack overflow... I found <a href="https://stackoverflow.com/questions/61793803/stack-overflow-thread-1-exc-bad-access-code-2-address-0x16d09aa00">this answer/question</a> where they have a very similar problem and were able to solve it by moving large structs to the heap. I am not certain how exactly to accomplish this, even after looking at the example provided in the answer.</p>
<p>My main thought is that there must be a better way to organize my body in the first place that I am just missing. Is using the heap really necessary for rendering a view with a lot of children? Any help or advice is appreciated.</p>

74,428,712 | <p>I am getting an array like below after doing the matches.
[ '10 am', '5 pm', 'by appointment only' ]
I would like to append text <strong>to</strong> only for time and return in this format.</p>
<p>"10 am to 5 pm by appointment only"</p>
<p>But when I join like below</p>
<pre><code>[ '10 am', '5 pm', 'by appointment only' ].join( 'to' );
</code></pre>
<p>I am getting result as</p>
<blockquote>
<p>"10 am to 5 pm to by appointment only"</p>
</blockquote>
<p>So with the help of regular expression is there a way to to remove <strong>'to'</strong> only from 3rd element of array so that when joining it won't append <strong>'to '</strong> again.</p>

74,428,716 | <p>I am new to Pandas and thus I wanted to know if I can convert my text file with a particular format into a Pandas data frame. Below is my text file format</p>
<pre><code>"FACT"|"FSYM"|"POSITION"|"INDIRECT_OPTIONS"|"REPORT"|"SOURCE"|"COMMENTS"|
"ABCX"|"VVG1"|2800000|760000|2022-11-03|"A"|"INCLUDES CAR"|0
</code></pre>
<p>I wanted to convert this format in Pandas with same columns and values as separated by | sign. That is my data frame columns will be FACT, FYSM,POSITION, and so on.</p>
<p>I am trying below code but it does not give me the desired output.</p>
<pre><code>def convert_factset_file_to_dataframe(test_case_name, file_name):
data = pd.read_csv("{}/output/Float_Ingestion_files/{}/{}.txt".format(str(parentDir), test_case_name, file_name), sep=',')
print(data)
</code></pre>
<p>It is printing as follows. Just adding the index.</p>
<pre><code> "FACT"|"FSYM"|"POSITION"|"INDIRECT_OPTIONS"|"REPORT"|"SOURCE"|"COMMENTS"|
0 "ABCX"|"VVG1"|2800000|760000|2022-11-03|"A"|"INCLUDES CAR"|0
</code></pre>
<p>Is there any other way of converting my text file format to a data frame besides reading it as a CSV? Or I need to incorporate some changes in the code?</p>

}
getlex();
return m;
}
</code></pre>
<p>Code performs almost everything mentioned, except power-operation. I can't find a bug. There is also an issue with right association of power operation. That means expression 3^1^2 gives 9, but should give 3.</p>
<p>Please help!</p>

74,428,727 | <p>I have a game in which the character can only move horizontally and vertically, not diagonally.</p>
<p>I have tried to implement this with this code, which should check if the player is pressing down/up or left/right:</p>

74,428,789 | <p>I have a class that looks like this</p>
<pre><code>class MyCalss
{
public:
std::unordered_map<std::string, std::unique_ptr<Entity>> getMyMap() const;
private:
std::unordered_map<std::string, std::unique_ptr<Entity>> m_myMap;
}
</code></pre>
<p>In the implementation, I simple return m_myMap in getMyMap() like so,</p>
<pre><code>std::unordered_map<std::string, std::unique_ptr<Entity>> MyClass::getMyMap() const
{
return m_myMap;
}
</code></pre>
<p>How come this is not allowed? I get a bunch of compilation error doing this.</p>

74,428,881 | <p>I have my <strong><em>custom</em></strong> <code>Bottom Navigation Bar</code> in one dart file, i.e. <code>bottomnavbar.dart</code>. And I have list of multiple <code>screens</code>(or pages) in my <code>home.dart</code> file. I am using an <code>.obs variable</code> to store my selected index value.
<br>code from <code>home.dart</code> file:</p>
<pre><code>var selectedIndex = 0.obs;
final screen = [
const Page1(),
const Page2(),
const Page3(),
const Page4(),
const Page5(),
];
...
body: screen[selectedIndex.value],
...
</code></pre>
<p>Even if I change the variable value (like <code>0.obs</code> to <code>1.obs</code>), page not changing, why??</p>
<p>next of, In my <code>bottomnavbar.dart</code> file, I have extracted and made a widget for my <code>nav bar 'items'</code>. And I have tried to wrap the item widget with Obx:</p>
<pre><code>Widget bnbItems(String image, int index, double height) {
return Obx(
() => InkWell(
splashColor: Theme.of(context).brightness == Brightness.dark
? Colors.white.withOpacity(0.5)
: Colors.pink.withOpacity(0.5),
enableFeedback: true,
onTap: () => setState(() {
selectedIndex.value = index;
_controller.animateTo(index / 4);
// print(selectedIndex);
}),
child: Container(
alignment: Alignment.center,
width: 50,
height: 50,
child: Padding(
padding: const EdgeInsets.only(top: 5.0),
child: Image.asset(
image,
height: height,
),
),
),
),
);}
</code></pre>
<p>and I am getting this error:</p>
<pre><code>[Get] the improper use of a GetX has been detected.
You should only use GetX or Obx for the specific widget that will be updated.
If you are seeing this error, you probably did not insert any observable variables into GetX/Obx
or insert them outside the scope that GetX considers suitable for an update
(example: GetX => HeavyWidget => variableObservable).
If you need to update a parent widget and a child widget, wrap each one in an Obx/GetX.
</code></pre>
<h4>Can anyone give me the solution with some code and explanation? And also how will I be able to set a particular screen as the initial screen?</h4>

<div class="snippet-code">
<pre class="snippet-code-js lang-js prettyprint-override"><code>function missingNumbers(arr){

74,429,033 | <p>I'm trying to handle silent notification sent to me from by backend which triggers Firebase services and it (probably?) triggers Apple servers to send the push.</p>
<p>I've selected Remote notifications and Background fetch in project's Signing & Capabilities: <a href="https://i.stack.imgur.com/RTr5G.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/RTr5G.png" alt="remote notifications and background fetch setting in xcode project" /></a></p>
<p>The usual notifications tested by Firebase console backend are working fine. Yet, while I want to handle the silent notifications (which I cannot send directly on Firebase console) by implementing the</p>
<pre><code>func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable : Any], fetchCompletionHandler completionHandler: @escaping (UIBackgroundFetchResult) -> Void)
</code></pre>
<p>method, I got nothing - the method <strong>is not called</strong> - while backend developer assures me that the silent push notification has been is sent (at least to Firebase).</p>
<p>The piece of code run on the backend to trigger Firebase silent notification looks somehow like this:</p>
<pre><code>ApnsConfig.builder()
.setAps(
Aps.builder()
.setCategory(pushType.toString())
.setContentAvailable(true)
</code></pre>
<p>I'm testing it while the app is running - since this silent notification is used to update the state of the app when user triggered something on the web just after he/she interacted with the website (by scanning the website QR code).</p>
<p>To debug it I'm trying to intercept all the connections using Charles application - but for now without any success (I'm not able to see even standard push notification being received - which is being shown). Maybe I should be able to see some logs in the Firebase console which I have not found yet?</p>
<p>How can I prove (or disprove) that the correct notification to the correct device is not being sent and received?</p>
<p>UPDATE:
Using Curl to fire background push is working - while using legacy method of sending the push</p>
<pre><code>curl --location --request POST 'https://fcm.googleapis.com/fcm/send' \
--header 'Authorization: key=HERE_AUTH_KEY' \
--header 'Content-Type: application/json' \
--data-raw '{

74,429,365 | <p>Consider the following Array:</p>
<pre><code>julia> test_mat3 = rand(2, 3, 2)
2×3×2 Array{Float64, 3}:
[:, :, 1] =
0.539697 0.17689 0.944783
0.537687 0.660573 0.19497
[:, :, 2] =
0.726739 0.798789 0.0900478
0.00744727 0.837076 0.25798
</code></pre>
<p>I want to reshape it into a 2d Array with a specific order. First, I want to concatenate <strong>each row of each inner matrix</strong> (here with shape 2x3). So for the first step, I expect several 1x6 inner matrixes. Second, I want to concatenate these matrixes vertically. The expected output on the <code>test_mat3</code> would be:</p>
<pre><code>2×6 Array{Float64, 2}:
0.539697 0.17689 0.944783 0.537687 0.660573 0.19497
0.726739 0.798789 0.0900478 0.00744727 0.837076 0.25798
</code></pre>
<p>However, I wrote this code:</p>
<pre><code>using SplitApplyCombine
function flatten_3d(arr::Array{Float64, 3})
mat = zeros(
Float64,
size(arr, 3),
size(arr, 1)*size(arr, 2)
)
for (idx, arr)=enumerate(splitdimsview(arr, 3))
the_vec = vcat(eachrow(arr)...)
mat[idx, :] = the_vec
end
return mat
end
</code></pre>
<p>The script does the job:</p>
<pre><code>julia> flatten_3d(test_mat3)
2×6 Matrix{Float64}:
0.539697 0.17689 0.944783 0.537687 0.660573 0.19497
0.726739 0.798789 0.0900478 0.00744727 0.837076 0.25798
</code></pre>
<p>But I wonder if there is any better way to do this? Any built-in function, etc.</p>

74,429,385 | <p>I am trying to download all CSV files from the <code>\tmp\</code> directory with a PS script and convert them to one excel file as a report and place it in the <code>\reports\</code> directory under the name <code>LDAP.xlsx</code> . My CSV files have varying amounts of saved data.</p>
<p>In the forum I found this <a href="https://stackoverflow.com/questions/17688468/how-to-export-a-csv-to-excel-using-powershell">how-to-export-a-csv-to-excel-using-powershell</a> and my code looks like this:</p>
<pre><code>Clear-Host
# SOURCE
##########
# config file
$conf_file = "C:\PS_LDAP_searchlight\config\searchlight_conf.conf"
$conf_values = Get-Content $conf_file | Out-String | ConvertFrom-StringData
# variables from config file
$main_path = $conf_values.main_path
$tmp_path = $conf_values.tmp_path
$reports_path = $conf_values.reports_path
# PROGRAM
##########
$workingdir = $main_path + $tmp_path + "*.csv"
$reportsdir = $main_path + $reports_path
$csv = dir -path $workingdir
foreach($inputCSV in $csv){
$outputXLSX = $reportsdir + "\" + $inputCSV.Basename + ".xlsx"
### Create a new Excel Workbook with one empty sheet
$excel = New-Object -ComObject excel.application
$excel.DisplayAlerts = $False
$workbook = $excel.Workbooks.Add(1)
$worksheet = $workbook.worksheets.Item(1)
### Build the QueryTables.Add command
### QueryTables does the same as when clicking "Data » From Text" in Excel
$TxtConnector = ("TEXT;" + $inputCSV)
$Connector = $worksheet.QueryTables.add($TxtConnector,$worksheet.Range("A1"))
$query = $worksheet.QueryTables.item($Connector.name)
### Set the delimiter (, or ;) according to your regional settings
### $Excel.Application.International(3) = ,
### $Excel.Application.International(5) = ;
$query.TextFileOtherDelimiter = $Excel.Application.International(5)
### Set the format to delimited and text for every column
### A trick to create an array of 2s is used with the preceding comma
$query.TextFileParseType = 1
$query.TextFileColumnDataTypes = ,2 * $worksheet.Cells.Columns.Count
$query.AdjustColumnWidth = 1
### Execute & delete the import query
$query.Refresh()
$query.Delete()
### Save & close the Workbook as XLSX. Change the output extension for Excel 2003
$Workbook.SaveAs($outputXLSX,51)
$excel.Quit()
# Cleaner
$inputCSV = $null
$outputXLSX = $null
}
## To exclude an item, use the '-exclude' parameter (wildcards if needed)
#remove-item -path $workingdir -exclude *Crab4dq.csv
# CLEANER
###############################
# SOURCE
###############################

$reports_path = $null
# PROGRAM
###############################
$workingdir = $null
$csv = $null
$reportsdir = $null
</code></pre>
<p>the code reads all files but writes one to one. I need help and explanation on how to make a many-to-one option. I would like each CSV file to be saved as a separate sheet under its own name like:</p>
<p>users_all_inf.csv in excel\sheet1 => users_all_inf<br />
active_users_last_logon_year_ago.csv in excel\sheet2 => active_users_last_logon_year_ago<br />
nextfilename.csv in excel\next_sheet => nextfilename</p>
<p>so that all data will be available in one excel report.xlsx file.<br />
I will be grateful for any hint or help in converting the code.</p>

74,429,458 | <p>I'm using Deadline monitor to automate a few processes. I don't think you'll need to know about Deadline to answer my question though.</p>
<p>I've created a Python script that takes a few arguments to be able to create the .bat file. I then want the same python script to run the .bat file to do what I need it to do. However, I'm not having any luck.</p>
<pre><code>def main(project_path, nuke_job_id):
dependencies_file = project_path + "\\" + "dependencies.txt"
with open(dependencies_file, 'r') as f:
Job_IDs = f.readlines()
# ------------- remove unwanted characters
list_string = str(Job_IDs)
beginning_ids = list_string.split("[")
end_ids = beginning_ids[1].split("]")
job_ids_string = end_ids[0].split("'") # position 1 has what is needed
# -------------
temp_id = '636e4b2a518c9b626412f608'
command = '"%deadline_path%"' + "\\deadlinecommand" + " " + "-SetJobSetting" + " " + temp_id + " " + "JobDependencies" + " " + job_ids_string[1]
bat_file = open(project_path + "\\" + "create_dependencies.bat", 'w+')
bat_file.write("@echo off" + "\r\r" + command)
bat_file.close()
print ('bat file closed')
bat_file_to_run = project_path + "\\" + "create_dependencies.bat"
time.sleep(5)
run_bat(bat_file_to_run)
def run_bat(bat_file_to_run):
print ("run_bat")
process = subprocess.Popen(bat_file_to_run, stdout=subprocess.PIPE)
# process = subprocess.call(bat_file_to_run)
process.wait()
</code></pre>
<p>If I run the script as it is, the .bat file is created but then nothing happens.
I tried to manually double click on it to make sure that it works, and interestingly it doesn't work either. However, if I copy the contents of the .bat file into a new one, and then run that one everything works as I want to.</p>
<p>Have I missed something on the automatic creation on the .bat file that it doesn't like it and nothing runs? I've run this script multiple times and I always get the same result. The automatically created .bat file doesn't do anything, but a new one with the exact same contents does work.</p>
<p>I'll share the .bat file code here as well just as reference.</p>
<pre><code>@echo off
"%deadline_path%"\deadlinecommand -SetJobSetting 636e4b2a518c9b626412f608 JobDependencies 636e3fb4d4682e9cb0790c47,636e3fbf76741b65388982ae,636e3fcc4ad53e99c0426f2a,636e3fd846409c9d10aff124,636e3fe5e740b57ee4e48ef7,636e3ff57883fc8c10294a0b,636e4000f47c7671583bfe1d,636e400b885d6e8970186399,636e40176be6ce9d80ce357c,636e4021b75ec99c8074b34b
</code></pre>
<p>I tried adding a pause at the end to be able to see what's happening, but it doesn't do it either. And like I said, if I create the .bat file manually, it works just as expected.</p>
<p>Thank you for your time. Hopefully someone will be able to point me in the right direction as I don't really know what's happening or why it's happening.</p>

74,429,460 | <p>I want to implement transparent status bar in jetpack compose.</p>
<p>I have integrated the Accompanist library for this but it has no transparent effect on status bar.</p>
<pre><code>implementation "com.google.accompanist:accompanist-systemuicontroller:0.18.0"
// Remember a SystemUiController
val systemUiController = rememberSystemUiController()
val useDarkIcons = !isSystemInDarkTheme()
DisposableEffect(systemUiController, useDarkIcons) {
// Update all of the system bar colors to be transparent, and use
// dark icons if we're in light theme
systemUiController.setStatusBarColor(
color = Color.Transparent,
darkIcons = useDarkIcons
)
// setStatusBarColor() and setNavigationBarColor() also exist
onDispose {}
}
</code></pre>
<p>Tried this as well, but it has problem with the gesture navigation</p>
<pre><code>val view = LocalView.current
if (!view.isInEditMode) {
SideEffect {
val window = (view.context as Activity).window
val insets = WindowCompat.getInsetsController(window, view)
window.statusBarColor = Color.Transparent.toArgb() // choose a status bar color
window.navigationBarColor = Color.Transparent.toArgb() // choose a navigation bar color
insets.isAppearanceLightStatusBars = !useDarkTheme
insets.isAppearanceLightNavigationBars = !useDarkTheme
}
}
</code></pre>
<p>Kindly suggest a better solution for the transparent status bar.</p>

74,429,469 | <p>I'm trying to understand how child_process works and I don't see any options to pass a variable to the child.
My situation:</p>
<blockquote>
<p>Main.js</p>
</blockquote>
<pre><code>[const arr = [10,20,30,40,50]
for (let g of arr ){
function(g) // I want to launch every loop in a separate process because there are a lot of async functions inside and it takes a lot of time to process.
}
</code></pre>
<blockquote>
<p>First I tried child_process.fork :</p>
</blockquote>
<p><code>//Main.js</code></p>
<pre><code>const { fork } = require('child_process');
const forked = fork('test/child.js');
for (let g of arr){
forked.send(g);
}
</code></pre>
<p><code>//Child.js</code></p>
<pre><code>process.on('message', (msg) => {
console.log('Message from parent:', function(msg));
});
</code></pre>
<p>Child.js received variable g, but the process of the function's execution became much longer than a simple loop.</p>
<blockquote>
<p>Second I tried child_process.execFile</p>
</blockquote>
<p><code>//I made a simple loop from 0 to 5 to see the speed without sending variables</code></p>
<pre><code>for (let i = 0;i< arr.length;i++){
const { execFile } = require('child_process');
const child = execFile('node', ['test/child.js'],
(error, stdout, stderr) => {
if (error) {
throw error;
}
console.log(stdout);
});
}
</code></pre>
<p>Here I got a perfect result. 5 fast and paralleled executions. But as I see there is no way to send this integer from the array to the child.js and other child methods allow only to send arguments for the command line, but not variable? Maybe there are some ways to do it?
Sorry for my confusing text and thanks.</p>

74,429,477 | <p>Write a PLSQL function that checks whether the salary of an employee
is less than the average salary of all the employees. If the salary is lees,
the program should update the salary of that employee by 5% of their current salary and print
the old employee salary, the average salary of all the employees, and the new employee
salary after update. Your program should handle all the possible exceptions.
Your output should be formatted as below:</p>
<pre><code>O/P: Old salary is: $510
Avg salary is: $957.05
New salary is: $765

74,429,488 | <p>How can I select all rows/unselect all rows of a WPF datagrid on a button click without messing up the MVVM pattern ?</p>
<p>Currently I doing something like this:</p>
<h1>XAML</h1>
<pre><code><Button Command="{Binding SelButtonClicked}" .../>
</code></pre>
<p>and in the Mainviewmodel</p>
<pre><code>public RelayCommand SelButtonClicked { get; set; }
...
Public Mainviewmodel()
{
SelButtonClicked = new RelayCommand(SelUnsel);
}
...
public void SelUnsel(object param)
{
var win = Application.Current.Windows
.Cast<Window>()
.FirstOrDefault(window => window is MainWindow) as MainWindow;
if (win.myGrid.SelectedItems.Count > 0)
{
win.myGrid.UnselectAll();
}
else
{
win.myGrid.SelectAll();
}
}
</code></pre>
<p>But I'm pretty sure it is not the MVVM way ...</p>

74,429,498 | <p>In a Doctrine Collection, I have identical objects, each with an integer property '<code>player</code>' and another integer property called '<code>team</code>'. Player could be <code>1,2,3...</code> and Team can be <code>0,1,2,3,...</code> and so on. <code>0</code> means '<code>default team</code>'. All players belong to the default team first and foremost. A player can then become a member of other teams too. For example, player <code>2</code> can be a member of team <code>0, 2</code> and <code>3</code>.</p>
<p>Now, I would like to get the object where <code>Player 3</code> is a member of <code>Team 2</code>. If not, return the object where <code>Player 3</code> is a member of <code>Team 0</code>.</p>
<p>How would I achieve this?</p>

74,429,550 | <p>I have a UTC date-time like this (a String): <code>2022-11-22T17:15:00</code></p>
<p>And a ZoneID like this: <code>"America/Tijuana"</code></p>
<p>Using java.time API, I want to get the actual datetime for that zone, which is: <code>2022-11-22T09:15:00</code> (the time is 09:15 instead of 17:15)</p>
<ul>
<li>ZonedDateTime.toLocalDateTime() returns: <code>2022-11-22T17:15</code></li>
<li>ZonedDateTime.toString() returns:
<code>2022-11-22T17:15-08:00[America/Tijuana]</code></li>
</ul>
<p>None of the above gives me what I'm looking for.</p>
<p>This is my code:</p>
<pre><code> ZoneId zonaID = ZoneId.of('America/Tijuana');
CharSequence dateUTC = "2022-11-22T17:15:00";
LocalDateTime dateTimeL = LocalDateTime.parse(dateUTC);
ZonedDateTime myZDT = ZonedDateTime.now();
ZonedDateTime myZDTFinal = myZDT.of(dateTimeL, zonaID);
System.out.println("using toLocalDateTime: " + myZDTFinal.toLocalDateTime());
System.out.println("using toString: " + myZDTFinal.toString());
</code></pre>
<p>I know that this might be a duplicated question but there's so many questions about date-times and I just haven't been able to figure out this.</p>
<p>Any help will be really appreciated.</p>

74,429,635 | <p>Following is the Clojure code:</p>
<pre><code>(reduce (fn [r x] (if (nil? x) r (conj r x)))
[]
[:mouse nil :duck nil :lory nil])
</code></pre>
<p>In REPL, it evaluates to <code>[:mouse :duck :lory]</code>.</p>
<p>My question is, how is the code evaluating?</p>
<p>According to me, <code>r</code> is <code>[]</code> and <code>x</code> is <code>[:mouse nil :duck nil :lory nil]</code>. <code>nil? x</code> is false as so it evaluates to <code>(conj r x)</code>. But x is a vector, not an element so how it will add an element to the empty vector r in <code>conj</code>? I don't know but I am wrong somewhere in my approach. The output is the animals' name vector without nil values.
Can anyone please explain me the execution of code. Thanks.</p>

74,429,665 | <p>I am new to Typescript and trying to use Redux-Toolkit with it in my React application. Here I am trying to create a To Do application with a nested state where each <code>ToDo</code> contains a array of <code>Comment</code>. Here are the interfaces:</p>
<p><code>Comment.ts</code></p>
<pre><code>export interface Comment {
id: number;
comment: string;

</code></pre>
<p><code>ToDo.ts</code></p>
<pre><code>export interface ToDo {
id: number;
title: string;
description: string;
comments: Array<Comment>;
}
</code></pre>
<p>Then in my <code>ToDoSlice</code>:</p>
<pre><code>export const toDoSlice = createSlice({
name: 'toDoSlice',
initialState: [] as Array<ToDo>,
reducers: {
addToDo: (state, action: PayloadAction<ToDo> ) => {
state.push(action.payload);
},
}
});
</code></pre>
<p>The TS compiler throws this on the line <code>state.push(action.payload)</code>:</p>
<pre><code>TS2345: Argument of type 'ToDo' is not assignable to parameter of type 'WritableDraft<ToDo>'.

<br>
<p>I tried to cast the <code>action.payload</code> to type <code>WritableDraft<ToDo></code>, and the error does go away.</p>
<pre><code>addToDo: (state, action: PayloadAction<ToDo> ) =>
{state.push(action.payload as WritableDraft<ToDo>);
},
</code></pre>
<p>However, similar problem arises when I try to add a <code>Comment</code> into an existing <code>ToDo</code>:</p>
<pre><code>addComment: (state, action: PayloadAction<{toDoId: number, comment: Comment}>) => {
const toDo = state.find(toDo => toDo.id === action.payload.toDoId);
if (toDo) {
toDo.comments.push(action.payload.comment);
}
}
</code></pre>
<p>where it gives another error:</p>
<pre><code>Argument of type 'Comment' is not assignable to parameter of type 'WritableDraft<Comment>'.
Type 'Comment' is missing the following properties from type 'WritableDraft<Comment>': data, length, ownerDocument, appendData, and 59 more.

<p>and casting <code>action.payload.comment as WritableDraft<Comment></code> won't do. The error almost remains the same.</p>

<pre class="lang-java prettyprint-override"><code>Integer[] = {1,2,3,4,5,6,7,8,9,10};
</code></pre>
<p>i.e. all the Integer elements should be stored</p>
<p>What I did is</p>
<pre><code>for(Object obj: array){
if(obj instanceof Integer) list.add((int)(obj));
}
</code></pre>
<p>Which results in -> 1,2,8,9,10. How do I add 3,4,5,6,7 inside list?</p>

74,429,701 | <p>I'm currently building a program in JavaScript that is making requests of the google sheets API based on activity occurring in a Discord Server (messaging app). However, I've been running into the API RateLimits in cases where multiple users do the same action at the same time, causing too many API Requests in too short of a time.</p>
<p>My idea to get around this is to implement a parallel queue of async function calls, so that whenever I want to make a request of the google API, I queue that function call, and another function or thread or <em>something</em> will keep checking this queue and if there is a function available, it will run that function, wait a little bit, and then check the queue again, and so on.</p>
<p>I'm struggling to figure out how to do this in regular asynchronous (async/await) programming. I've been referring to the following posts/pages, but they all seem focused on a predefined queue that is then dequeued in order - I want to be able to keep adding to the queue even after the functions have started being run.

74,429,721 | <p>Hey guys so I am trying to resize my tkinter window using the geometry function if the master window.</p>
<p>I am able to resize it when I tried to do that without creating a class.</p>
<p>But when I tried to resize the window made by the class method I came across a method where the master was resized before passing it as a parameter in the class initialization.</p>
<p>But when I tried to do that without passing the master without passing it as a parameter my interpreter crashes.</p>
<p>What I want to know is what I am doing is it correct?</p>
<p>If not please help me understand why is the interpreter crashing.</p>
<p>Here is the code that I Tried to run.</p>
<pre><code>class App(Tk):
def __init__(self):
self.geometry('300x300')
#self.tk.Tk.geometry('300x300') Tried this but it didn't do anything.
Label(text='Post Navigation Button').grid(row=0,column=0)
self.listbox = Listbox(selectmode='multiple',height=len(x))
for each_item in range(len(x)):
self.listbox.insert(END, x[each_item])
self.listbox.itemconfig(each_item, bg = "lime")
self.listbox.grid(row=0,column=1)
self.tag = Text(height=1,width=100)
self.tag.grid(row=0,column=2)
Button(text='click me',command=self.submit).place(x=500,y=50)
def submit(self):
text = self.tag.get('0.0',END)
selection = [self.listbox.get(i) for i in self.listbox.curselection()]
print(text.strip(),','.join(selection))
app = App()
mainloop()
</code></pre>
<p>I don't want to create a master and pass it as a parameter like this.</p>
<pre><code>root = tk.Tk()
root.geometry('300x300')
app = App(root)
mainloop()
</code></pre>
<p>So I just want to know the way to resize the the window from inside the class.</p>
<p>I don't know how correct my code is. So any help is welcome.</p>

74,429,952 | <p>I have the following Pd series</p>
<pre><code> count area volume formula quantity
0 1.0 22 NaN count 1.0
1 1.0 15 NaN count 1.0
2 1.0 1.4 NaN area 1.4
3 1.0 0.6 10 volume 100
</code></pre>
<p>The quantity column is based on the value in the formula column via a lookup e.g. row(0) is "count" so it is 1, row(2) is "area" so it's 1.4</p>
<p>For this I have a the following formula</p>
<pre><code>Merged['quantity']=Merged.apply(lambda x: x[x['QuantityFormula']] , axis=1)
</code></pre>
<p>However quantity for volume is a calculated field: volume * 10. I've written a function to calculate both</p>
<pre><code>def func(x):
if x[x['QuantityFormula']] == Volume:
return volume * 10
else:
return x[x['QuantityFormula']]
df['Classification'] = Merged['QuantityFormula'].apply(func)
</code></pre>
<p>However I get the following error</p>
<pre><code>Error: string indices must be integers
</code></pre>
<p>Any ideas? Thanks</p>
<p>Answer</p>
<pre><code>def func(row):
if row['QuantityFormula'] == 'Volume':
return row['Volume'] * 10
return row[row['quantity']]
Merged['Ans'] = Merged.apply(func, axis=1)
</code></pre>

74,429,956 | <p>I'm confused on how do I add a column to another in pandas</p>
<p>Here is what I'm trying to do :</p>
<pre><code>from pandas import DataFrame
df1 = DataFrame({'a':[1,2], 'b':[3,4]})
concat((df1['a'], df1['b'].rename({'b':'a'}))).reset_index(drop=True)
</code></pre>
<p>Which do return what I want : A serie with my 4 values. What I don't understand is : Why I can't assign it to column 'a' ?</p>
<pre><code>>>> from pandas import DataFrame
>>> df1 = DataFrame({'a':[1,2], 'b':[3,4]})
>>> concat((df1['a'], df1['b'].rename({'b':'a'}))).reset_index(drop=True)
0 1
1 2
2 3
3 4
dtype: int64
>>> df1['a'] = concat((df1['a'], df1['b'].rename({'b':'a'}))).reset_index(drop=True)
>>> df1
a b
0 1 3
1 2 4
</code></pre>
<p>Is there any way to make it more readable by the way? I'm confused on how it should worked... Note that I don't need column 'b' afterward.</p>
<p>Thanks for your help :)</p>
<p>Sam</p>

74,429,998 | <p>I wanted to declare an array with a pointer in character type, and the length of the array can be determined by my input string.</p>
<p>I wrote it in this way:</p>
<pre class="lang-cpp prettyprint-override"><code>char *s;
cout << "Enter a string: " << endl;
cin >> s;
</code></pre>
<p>I expected that I can initialize the string by the <code>cin</code> operation, but an error showed up when compiling. The error is about "invalid operands to binary expression".</p>
<p>I'm not sure why the lines I wrote was wrong.
I though not only the built in <code>string</code> class is used for declaring an array.</p>
<p>Isn't the <code>string</code> data type in C++ the same as "a character array"?</p>
<p>Isn't the line <code>char *s</code> means the pointer <code>s</code> points to an character array (or string)?</p>
<p>Thank you!</p>

74,430,017 | <p>For my accessibility related question, I googled "accessibility shopping cart" and visited many popular online stores but didn't find a clear answer on my question.
