In Flutter we do serialization (toJson) of the model, but how can we generate toJson that includes the getters?
Simple example
class MyClass {
const MyClass({
required this.a,
required this.b,
});
final double a;
final double b;
double get average => (a + b) / 2;
}
We use `json_serializable` package for generating the `toJson` method.
It generate the `my_class.g.dart` file where we have toJson and fromJson methods.
The problem is that in this way we do not have a serialization of the getter (`average` field in our example).
What can we do to provide the full serialization including class getters?
Is there a way to achieve it using `json_serializable` package or some other package offers that?

You can alias your fields using `.` to build document structure. For your case, you can do this:
drop table if exists #Project
create table #Project
(
Id int identity(1, 1),
Description nvarchar(100),
Note nvarchar(100)
)
insert into #Project
values
('Daphne', 'Ocala county - Barn'),
('Sunny', 'Riverdon county - Prison'),
('Sasha', 'Sommer county - School')
select
(
select
[ExternalRefNbr.value] = cast(Id as nvarchar(30)),
[Description.value] = Description,
[Note.value] = Note
for json path, without_array_wrapper
)
from #Project |
Ran into a similar problem in vba and this worked for me, maybe you can leverage something similar?

As per Json Schema documentation,
**Contains** means that at least one item of the array is valid
**Items** means that all elements of the array are valid
https://json-schema.org/understanding-json-schema/reference/array
So it's up to your use-case to determine if you want to validate at least one or everything |

I have a compiled application (written in Go if it matters). The application should run as a daemon in Linux and write logs to the user's home directory. The problem is that the daemon will be launched as root, and the home directory will be that of root.
I tried to add the following line to the postinst script of the deb package:
`sed -i "s:%homedir%:${HOME}:g" /lib/systemd/system/mydemon.service`
(My application has a CLI parameter that accepts the directory for log writing.)
But if the installation is done with sudo, then we'll get the wrong directory.
I also tried getting the user's home directory in the program itself using `os.UserHomeDir()`, but it returns the root directory if the application runs under root.
Perhaps there's a way to obtain the home directory based on the session. For example, in Windows, my service also runs under the "SYSTEM" account, but I get the current user's directory through the session (using WinAPI, getting the UserToken, then GetUserProfileDirectory).
Is there something similar that can be done in Linux?

A lot depends on the weights on your edges. You'll get very different values depending on the weights and how those weights are being interpreted. You'll undoubtedly need to open up the Layout->Settings... dialog for the spring embedded layout and play with the values to get the results you want.

Edit: I'm doing away with pseudocode, here's the actual code. <br>
I think the answer to question may lie [here](https://stackoverflow.com/questions/14220321/how-do-i-return-the-response-from-an-asynchronous-call/14220323#14220323), but I can't understand the answer.
The value of `searchedItem` remains unaltered. The following is my actual code.
```lang-js
const searchedItem = async (req, res) => {
const { requestedId } = req.query
const client = await getClient()
try {
let searchedItem = 'literallyAnything'
const allCollections = await db('dbName').listCollections().toArray()
allCollections.forEach(async (collection) => {
const allUnits = await client
.db('dbName')
.collection(collection.name)
.find({})
.toArray()
for (const topic of allUnits) {
if (typeof topic === 'object' && Object.keys(topic).length > 1) {
for (const item in topic) {
if (typeof topic[item] === 'object') {
if (topic[item].id == requestedId) {
searchedItem = await topic[item]
break
}
}
}
}
}
})
res.status(200).json(searchedItem)
} catch (error) {
// res.status(500).json(error)
}
}
```
So, as mentioned above I read this [answer](https://stackoverflow.com/questions/14220321/how-do-i-return-the-response-from-an-asynchronous-call/14220323#14220323), but I don't understand it.
To tackle the above, I decided to create another method whose sole job would be to send response to the frontend. And I decided to call it from the if statement itself, where I know the value of `searchedItem` still exists, which worked upto an extent. What I mean by that is, I do get the desired output in my browser, but additionally I also get the error `Error [ERR_HTTP_HEADERS_SENT]: Cannot set headers after they are sent to the client`, and my server crashes. I'm truncating the code for sake of brevity.
```lang-js
// The new method that I created
const sendResponse = (response, statusCode, data) => response.status(statusCode).json(data)
```
```lang-js
// Including only the modified if statement
if (topic[item].id == requestedId) {
searchedItem = currentChild
sendResponse(res, 200, searchedItem)
}
```
What change should I implement in my code?

I downloaded the library https://github.com/mgp25/Chat-API.
This API whatsapp. I do everything as written in the documentation (github.com/mgp25/Chat-API/wiki).
First, I wrote the following script:
<?php
require_once 'src/Registration.php';
$debug = true;
$username = '123456789'; //my phone number
$w = new Registration($username, $debug);
$w->codeRequest('sms');
?>
Then, on my phone received a message with the code for registration.
Next, I wrote the following script:
<?php
require_once 'src/Registration.php';
$debug = true;
$username = '123456789';
$w = new Registration($username, $debug);
$w->codeRegister('654321'); //сode, that I have received
?>
In response, I received:

[login] => login
[pw] => password
[type] => existing
[expiration] => 1443256747
[kind] => free
[price] => 39.0
[cost] => 0.89
[currency] => руб
[price_expiration] => 1414897682
Next, I try to login:
<?php

require_once 'src/whatsprot.class.php';
require_once 'src/events/MyEvents.php';
date_default_timezone_set('Europe/Moscow');
$username = '123456789';
$password = 'password';
$nickname = 'nickname';
$debug = true;
$w = new WhatsProt($username, $nickname, $debug);
$w->connect();
$w->loginWithPassword($password);
Here, the script goes into an infinite loop.
Function `loginWithPassword()` is in file whatsprot.class.php:

I read in https://stackoverflow.com/questions/58039214/next-js-pages-end-in-404-on-production-build that perhaps it has something to do with having sub-folders inside the `pages` folder, but I'm not sure how to fix that as I wasn't able to get it to work without sub-foldering `page.js` files for each page.

I am trying to use the **Microsoft.Build** nuget package to:
- open a solution
- enumerate projects in it
- discover the DLLs that are created.
<sup>\<rant>Failure modes seem to be super-abundant, error messages are uninformative, documentation seems to be scarce and misdirected, and examples are outdated. After hours upon hours of troubleshooting in the dark, and solving issue after issue that popped up, I finally arrived at an "Internal MSBuild Error", which brings me to Stack Overflow.\</rant></sup>
My "scratch" solution contains just one net8.0 project, as follows:
<Project Sdk="Microsoft.NET.Sdk">
<PropertyGroup>
<OutputType>Exe</OutputType>
<TargetFramework>net8.0</TargetFramework>
</PropertyGroup>
<ItemGroup>
<PackageReference Include="Microsoft.Build" Version="17.9.5" />
<PackageReference Include="Microsoft.Build.Utilities.Core" Version="17.9.5" />
</ItemGroup>
</Project>
This project contains just one source file, as follows:
namespace ConsoleApp1;
using System;
using System.IO;
using System.Collections.Generic;
using Microsoft.Build.Construction;
using Microsoft.Build.Definition;
using Microsoft.Build.Evaluation;
using Microsoft.Build.Evaluation.Context;
class Program
{
static void Main( string[] args )
{
Directory.SetCurrentDirectory( @"C:\" ); //ensure that the error we encounter further down is not due to the current directory
msBuildApiTest( @"D:\Personal\MyVisualStudioSolution\Solution.sln" ); // <-- this fails
msBuildApiTest( @"D:\Personal\scratch\scratch.sln" ); // <-- this would also fail
}
static void msBuildApiTest( string solutionFilePath )
{
string msBuildExtensionsPath = @"C:\Program Files\dotnet\sdk\8.0.102";
string msBuildSdksPath = Path.Combine( msBuildExtensionsPath, "Sdks" );
Environment.SetEnvironmentVariable( "MSBuildSDKsPath", msBuildSdksPath ); //Prevents InvalidProjectFileException: The SDK 'Microsoft.NET.Sdk' specified could not be found.
Environment.SetEnvironmentVariable( "MSBuildEnableWorkloadResolver", "false" ); //Prevents InvalidProjectFileException: The SDK 'Microsoft.NET.SDK.WorkloadAutoImportPropsLocator' specified could not be found.
ProjectOptions projectOptions = new();
projectOptions.EvaluationContext = EvaluationContext.Create( EvaluationContext.SharingPolicy.Shared );
projectOptions.LoadSettings = ProjectLoadSettings.DoNotEvaluateElementsWithFalseCondition;
projectOptions.GlobalProperties = new Dictionary<string, string>();
projectOptions.GlobalProperties.Add( "SolutionDir", Path.GetDirectoryName( solutionFilePath ) + "\\" ); //The trailing backslash is OF PARAMOUNT IMPORTANCE.
projectOptions.GlobalProperties.Add( "MSBuildExtensionsPath", msBuildExtensionsPath ); //Prevents InvalidProjectFileException: The imported project "D:\Personal\scratch\ConsoleApp1\bin\Debug\net8.0\Current\Microsoft.Common.props" was not found.
ProjectCollection projectCollection = new( ToolsetDefinitionLocations.Default );
SolutionFile solutionFile = SolutionFile.Parse( solutionFilePath );
foreach( ProjectInSolution projectInSolution in solutionFile.ProjectsInOrder )
{
if( projectInSolution.ProjectType is SolutionProjectType.SolutionFolder or SolutionProjectType.SharedProject )
continue;
Console.WriteLine( $"{projectInSolution.ProjectType}\t{projectInSolution.ProjectName}\t{projectInSolution.RelativePath}" );
Project project1 = Project.FromFile( projectInSolution.AbsolutePath, projectOptions ); // <-- this fails
Project project2 = new( projectInSolution.AbsolutePath, projectOptions.GlobalProperties, "Current", projectCollection ); // <-- this would also fail
}
}
}
Either of the last two statements fails.
The exception is a `Microsoft.Build.Exceptions.InvalidProjectFileException`.
The message of the exception is as follows:
> `The expression "[MSBuild]::GetTargetFrameworkIdentifier(net8.0)" cannot be evaluated.`
> `MSB0001: Internal MSBuild Error: A required NuGet assembly was not found.`
> `Expected Path: D:\Personal\scratch\ConsoleApp1\bin\Debug\net8.0`
> `C:\Program Files\dotnet\sdk\8.0.102\Sdks\Microsoft.NET.Sdk\targets\Microsoft.NET.TargetFrameworkInference.targets`
Note: The "Expected Path" (whatever that means) points to the output directory of my scratch solution, which makes no sense, because that's not the solution I am trying to parse, and I have not supplied Microsoft.Build with any path to my scratch solution. As a matter of fact, I even switch the current directory to `C:\` so as to make sure that the error is not due to that.
Note: The `string msBuildExtensionsPath = @"C:\Program Files\dotnet\sdk\8.0.102";` part works on my machine, you might have to change it for your machine. Automatic discovery would be nice, but it is beyond the scope of this scratch app.
Note: The solution at "D:\Personal\MyVisualStudioSolution\Solution.sln" is the solution that I am trying to parse, consisting of many net8.0 C# projects and one net472 project. However, it does not matter, because I get the exact same failure when I point this simple scratch app to try to parse itself.
The question is: Why is this failing, and what must I do to make it work? |

I have a VM and and i encrypt my OS disk. Now everything functions as normal. I can see a small lock on the c:\ drive.
But the question is whats the real purpose of the encryption ? How does it protect the disks , in what way ? I mean another user that has access can come and rdp and still view the disk ?
So in what scenario is this of any use ?
How does it stop unauthorised access, I mean some one can take the disks , attach to a VM and they have the data ? (is that right?)
Also if i was to take a snapshot and create a new VM with these disks , will the encryption still be there ?
**UPDATE**
*Encrypting the OS disk ensures that data remains inaccessible without the encryption key, deterring unauthorized access even if the disk is stolen*
You mention the data inaccessible if the disk is stolen , how does that work ?
So if the disk is encrypted on my Azure subscription via Key Vault entires that hold the encryption keys , does that mena that if i restore the snapshots on my tenant then it will work ?
Does it mean if the disks and snapshots are stolen and someone tries to restore the disks to a Vm then it wont work because it cant find the Key Vault keys on their tenant ?
Is that how it works? |

I'm currently trying to apply an Edge-weighted Spring Embedded Layout algorithm in Cytoscape to a network, following the Materials and Methods from a study. When I apply the Layout, I'm not obtaining the same results.
In my case I'm having some nodes pointing outwards and some others highly concentrated in the middle of the graph, but I want the nodes to be equally distributed in the surface. This is what I have:
![What I obtain][1]

And this is what I want:

How can I change the parameters in Cytoscape to obtain this layout? |
I have two applications: one is an ASP.NET Core Web API and the other is a Maui Blazor application.
I successfully logged into Azure using `PublicClientApplicationBuilder` with my client ID. However, I'm encountering an issue with the access token.
I want to utilize the same access token that I obtained and send it to my API project for authentication. Is this achievable? If so, could someone provide me with an example of how to configure the `program.cs` file in the API project to validate the access token? |

I have a `ChildView` that you can access via `NavigationLink` and that will display in a `NavigationSplitView`’s detail pane.
NavigationSplitView {
ListView()
} detail: {
}
And
.navigationDestination(for: ChildModel.self) { post in
ChildView()
}
`ChildView` declares an Environment property for the model context:
@Environment(\.modelContext) private var modelContext
It also has a SwiftData `@Query` property declared to retrieve all stored DbModel objects:
@Query private var dbModel: [DbModel]
However, it always returns empty (when it is not true) and I see this warning pop:
> Set a .modelContext in view's environment to use Query
I have seen https://stackoverflow.com/questions/76878894/query-in-view-with-model-container-attached-shows-error-saying-it-does-not-hav which is similar but I wanted to follow up for a better understanding.
If I follow the advice in the answer above, and drop the @Query to replace with a `FetchDescription` in the `ChildView` constructor:
init() {
let predicate = #Predicate<DbModel> {
$0.id == self.id
}
let descriptor = FetchDescriptor<DbModel>(predicate: predicate)
if let models = try? modelContext.fetch(descriptor) {
/// do something here
}
}
It crashes:
> Thread 1: Fatal error: 'try!' expression unexpectedly raised an error: SwiftData.SwiftDataError(_error: SwiftData.SwiftDataError._Error.loadIssueModelContainer)
And has an accompanying warning:
> Accessing Environment<ModelContext>'s value outside of being installed on a View. This will always read the default value and will not update.
If I instead I refer to a reference of the context that I store after an app launch, it works fine:
if let models = try? AppController.shared.modelContextReference.fetch(descriptor) {
That’s progress, but I would appreciate clarification on two things:
1) How can I ensure the `ChildView` has environment access to the model context from a SwiftUI perspective, and for it to return the correct results (with no warning)? As in without needing to refer to a stored reference inside a class object.
2) I know `@Query` automatically stays up to date every time my data changes, and will reinvoke my SwiftUI view so it stays in sync. However, given I’m being forced to use a `FetchDescriptor` in the view’s constructor, does the same hold true? As in will the view — depending on a `FetchDescriptor` inside the `.init()` and not a `@Query` — also update whenever there are changes detected to the DbModel set?
The wider context is I am only interested in `DbModel` results for `ChildView` that are relevant (i.e. share the same id). So I’m also curious whether — [short of having ability to dynamically query][1] — that this will perform similarly to a `@Query` that has a filter defined with no dynamic value check.

I have 2 clusters,both publicly accessible,same security groups,but in different public subnets,I can connect to one cluster from local, but not the other.
Tried connecting via cluster ip, tried adding my ip as well as 0.0.0.0/0 to security groups, rebooted cluster after allowing public access, nothing helped.
Edit:
Solution:
When configuring cluster, I get to select the subnet group, and I chose the default one, which was a mixture of public and private subnets. So AWS randomly chose a subnet from it for my cluster, which was a private one. that is why I haven't been able to connect to it via local. |
class ItemGetter extends EventEmitter {
constructor () {
super();
this.on('item', item => this.handleItem(item));
}
handleItem (item) {
console.log('Receiving Data: ' + item);
}
getAllItems () {
for (let i = 0; i < 15; i++) {
this
.getItem(i)
.then(item => this.emit('item', item))
.catch(console.error);
}
console.log('=== Loop ended ===')
}
async getItem (item = '') {
console.log('Getting data:', item);
return new Promise((resolve, reject) => {
exec('echo', [item], (error, stdout, stderr) => {
if (error) {
throw error;
}
resolve(item);
});
});
}
}
(new ItemGetter()).getAllItems()
You logic, for first, run loop with calling all GetItem, then output '=== Loop ended ===', and only after that run all promices resolution, so, if you want get result of each getItem execution independently of eachother, just don't abuse asynchronous logic, frequently right solution much simpliest, than it seems ;)
Note: in this solution, you will get the same output, because loop with getItem calling, runnung faster, then promises with exec, but in this case, each item will be handled exactly after appropriate promise will be resolved, except of awaiting of all promises resolution. But in case, when you whant to make method getAllItems, asyncronous too, and await, when all results will be handled, but still remaining each promise running independently, you should implement you own logic, eg, using counter of started getItem methods, which increments in a loop and decrements on each promise resolution, so, this can be not so trivial |
So, I recently tried to make a project using the CC1101 wireless module and the [RadioLib](https://github.com/jgromes/RadioLib) library. I tried the CC1101_Receive_Adress and CC1101_Transmit_Adress examples from said library when I noticed taht the last symbol in the "Hello world!" message was getting corrupted - it was alwys replaced with something random, such as ">$, "@" or something similar. I also tried sending a readout form a BMI sensor, but the other side did not recieve that at all and only showed the random symbols. I tried sending the readouts as an int, float and byte variables, but it did not help. What could be causing this? Is it more likely a software or a hardware problem?
The problems occured when using UNo R3 on the transmitting side and UNO R4 Wifi on the receivenig end, with pinouts the same on both sides:
Vcc -3.3V
GND - gnd
MOSI - d11
SClk - d13
MISO - d12
GDO2 - d2
GDO0 (optional, but connected) - d3
CSN - d10
I am not sure if that matters since the name of the module is always the same, but i used [this specific variant](https://www.aliexpress.com/item/1005006440698413.html?spm=a2g0o.productlist.main.47.72497ff7czTHpM&algo_pvid=5d370251-5dea-4290-bf35-31c045851554&algo_exp_id=5d370251-5dea-4290-bf35-31c045851554-23&pdp_npi=4%40dis%21CZK%21257.39%2111.73%21%21%2178.03%213.55%21%40211b612817115494208761030ec04b%2112000037175069114%21sea%21CZ%210%21AB&curPageLogUid=jRATp7SUW13F&utparam-url=scene%3Asearch%7Cquery_from%3A) of the CC1101.
If you need any more information, I'll do my best to provide it.
When traying to solve this problem I tried changing the sent data to a variable, but that did not get sent at all. I also plan to try and replace the modules, but I currently have no spares. |

So I need to find in the response the data of one card containing the value nmID 12383295.
Change "description": "Some text nere" to the value from the variable and send back.
Help me with advice, how to do this in Bubble.
I receive a list of products upon request via API. I need to find the one I need. For example, with nmID 12383295. Change its description.

The answer here is that your path to your project likely contains a space:
path/to/PycharmProjects/Foo Bar Project/main.py
^ ^
This means you may be able to do things such as install packages through the Terminal, but you'll get the SDK error afterwards. Once you Refactor the project directory (<kbd>SHIFT</kbd> + <kbd>F6</kbd> or right-click on the project directory and select **Refactor**) to remove the spaces in the path, you should be able to run without seeing the SDK error.

I am trying to make a decision tree using rpart function in r. I have the y variable "outcome" and 4 variables as x. All of them are factors. Every tree I tried to make returns only the first node when I plot it.
Here is the code:
```
library(rpart)
library(rpart.plot)
train<-read.csv('train.csv', head=T, sep=",", dec=".")
train$gender<-factor(train$gender)
train$hr<-factor(train$hr)
train$sbp<-factor(train$sbp)
train$dbp<-factor(train$dbp)
train$outcome<-factor(train$outcome)
model <- rpart(outcome~., data=train, method="class")
rpart.plot(model)
```
At `model <-` I tried using any other combination and not with all the variables but again I had the same problem. I also tried using numeric variables and they worked with the "outcome" variable. |

if (bindingResult.hasErrors()) {
model.addAttribute(ERROR_MESSAGE_ATTRIBUTE, "Es gab Probleme, den Beitrag anzulegen. Versuche es erneut.");
return TEMPLATE_LOCATION;
}
try {
postService.savePost(postDto);
model.addAttribute(SUCCESS_MESSAGE_ATTRIBUTE, "Beitrag wurde erstellt!");
} catch (RuntimeException e) {
model.addAttribute(ERROR_MESSAGE_ATTRIBUTE, e.getMessage());
}
return TEMPLATE_LOCATION;
}
```
ServiceImpl:
```java
@Override
public void savePost(PostDto postDto) {
Authentication authentication = SecurityContextHolder.getContext().getAuthentication();
User user = userService.findByMailAddress(authentication.getName());
if (!permissionService.canCreatePosts(user)) {
throw new InsufficientPermissionsException(INSUFFICIENT_PERMISSIONS_EXCEPTION);
}
Post post = Post.builder()
.title(postDto.getTitle())
.content(postDto.getContent())
.visibility(postDto.getVisibility())
.event(eventService.getById(postDto.getEventId()))
.topic(topicService.getById(postDto.getTopicId()))
.creator(user)
.creationDate(LocalDateTime.now())
.build();
postRepository.save(post);
topicService.mailToSubscribers(post.getTopic());
}
```
Using the Spring Data JPA the object should get persisted in a database and users can read the post on the site.
After submitting the form, i logged the PostDto object and its already messed up and character like "ä", "ö", "ü" or other will be replaced with a "?".
PostDto:
```java

I'm using stringApp (v2.0.2) with Cytoscape (Version: 3.10.1).

A network diagram was usually occurred, and I could get data what I want until December 2023. |
Resource `google_service_account_iam_member` allows you to add members that can be used by the service account that is getting access. In [this example][1], SA is getting the possibility to use default GKE SA :
data "google_compute_default_service_account" "default" {
}
resource "google_service_account" "sa" {
account_id = "my-service-account"
display_name = "A service account that Jane can use"
}
# Allow SA service account use the default GCE account
resource "google_service_account_iam_member" "gce-default-account-iam" {
service_account_id = data.google_compute_default_service_account.default.name
role = "roles/iam.serviceAccountUser"
member = "serviceAccount:${google_service_account.sa.email}"
}
On the other side the resource `google_project_iam_member` grants access for identities to all resources in the project. With this example you will grant admin access to all Google Storage Buckets:
resource "google_service_account" "sa" {
account_id = "my-service-account"
display_name = "A service account that Jane can use"
}
resource "google_project_iam_member" "project" {
project = "your-project-id"
role = "roles/storage.admin"
member = "serviceAccount:${google_service_account.sa.email}"
}
The last option that you mentioned in the update is `google_compute_*_iam_member` which grants access on the resource level. That's why, when you will run this code sample you will grant admin access to only one Google Storage Bucket:
resource "google_service_account" "sa" {
account_id = "my-service-account"
display_name = "A service account that Jane can use"
}
resource "google_storage_bucket" "example" {
name = "example"
location = "US"
}
resource "google_storage_bucket_iam_member" "member" {
bucket = google_storage_bucket.example.name
role = "roles/storage.admin"
member = "serviceAccount:${google_service_account.sa.email}"
}
To follow the least privilege role assignment you should grant access to the specific Google service with the resources `google_compute_*_iam_member`. You can find these resources in the specific category in the Terraform registry. For example, I am resource for the storage bucket is placed in the `Cloud Storage` -> `Resources` -> [`google_storage_bucket_iam`][2]:

### Answer 2
If you comment out the two vispy lines in `update_data` and optionally add some prints, you'll notice that the GUI still acts the same. That is it freezes. So this has nothing to do with vispy.
As a general rule for realtime apps, any non-visualization operations should be in the separate thread (the data source). This includes your update interval logic. Put another way, only send data when the visualization should be updated.
In terms of the Qt event loop, you're basically dumping thousands of events onto the queue of tasks Qt has to process. Qt can't process any new UI events until it finishes handling of your data events. This basically ends up being a `for` loop in python over thousands of events.
The solution, at least to start, is to handle all your update interval stuff inside the data source thread. Only emit the signal when the data is ready to be displayed. Plus, 10000 points per second is a lot of data to view in realtime if that's your goal. You may need to work on averaging or subsetting the data to reduce how often you send updated data.
### Answer 1
It looks like this is based on the [vispy realtime data examples](https://vispy.org/gallery/scene/realtime_data/ex03b_data_sources_threaded_loop.html), right? When I wrote these I don't remember how much testing I did with a non-sleeping data source so there is always a chance that this code does not behave as I expect.
You mention this isn't updating in the "specified intervals", what do you mean by that? It could be that you are flooding the GUI with so many update events that it isn't able to update before you see the final result. Without your sleep (correct me if I'm wrong) you're basically going from the first iteration to the last iteration as fast as the CPU can go, right? In this case, what would you expect to see? In a more realistic example the data source creating the data would take some actual time, but your example creates all the data instantly. Are you sure the application is hanging or is it just done producing all the data?
If I'm wrong about all the above, then one difference I see is your use of `deque` which I have very little experience with. I'm wondering if you see any difference in behavior if you instead make a new numpy array inside your data source for every iteration. |
I am new to creating compilers and interpreters and as an exercise, I created a handwritten lexer in Java that spits out tokens looking like the following.
public Token(TokenType type, String lexeme, Object literal, int line) {
this.type = type;
this.lexeme = lexeme;
this.literal = literal;
this.line = line;
}
Now I want to create a parser using ANTLR, sadly I am running into some issues when trying to link my lexer with the ANTLR-generated parser. I have tried to implement a TokenSource (this is an ANTLR interface see: <https://www.antlr.org/api/Java/org/antlr/v4/runtime/TokenSource.html>), this can be used by a CharStream that the parser can use.
My first question: Is this a good approach or are there better ways to link a custom lexer with an ANTLR-generated parser?
My second question: ANTLR token types are integers, so the interface wants me to implement a getType() that returns an int. My token types are in an enum (so they are integers) but how do I link these integers/types with the ones in the ANTLR parser grammar (so they both see the type as the same type)? |

I am working on a virtualised data grid for my application.
I use transform: translateY for the table offset on scroll to make table virtualised.
I developed all the functionality in React 17 project, but when migrated to React 18 I found that the data grid behaviour changed for the worse - the data grid started to bounce on scroll.
I prepared the minimal representing code extract, which shows my problem.
To assure that the code is the same for React 17 and React 18, I change only the import of ReactDOM from 'react-dom/client' to 'react-dom' (which is of course incorrect, since the latter is deprecated) in my index.tsx file.

[enter image description here][1]
This is the code:
index.html
```
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8" />
<title>Virtuailsed table</title>
</head>
<body>
<noscript>You need to enable JavaScript to run this app.</noscript>
<div id="root"></div>
</body>
</html>
```
index.js
```
// import ReactDOM from "react-dom";
import ReactDOM from "react-dom/client";
import { useState } from "react";
import "./styles.css";
let vendors = [];
for (let i = 0; i < 1000; i++ ){
vendors.push({
id: i,
edrpou: i,
fullName: i,
address: i
})
}
const scrollDefaults = {
scrollTop: 0,
firstNode: 0,
lastNode: 70,
};
function App() {
const [scroll, setScroll] = useState(scrollDefaults);
const rowHeight = 20;
const tableHeight = rowHeight * vendors.length + 40;
const handleScroll = (event) => {
const scrollTop = event.currentTarget.scrollTop;
const firstNode = Math.floor(scrollTop / rowHeight);
setScroll({
scrollTop: scrollTop,
firstNode: firstNode,
lastNode: firstNode + 70,
});
};
const vendorKeys = Object.keys(vendors[0]);
return (
<div
style={{ height: "1500px", overflow: "auto" }}
onScroll={handleScroll}
>
<div className="table-fixed-head" style={{ height: `${tableHeight}px` }}>
<table style={{transform: `translateY(${scroll.scrollTop}px)`}}>
<thead style={{ position: "relative" }}>
<tr>
{vendorKeys.map((key) => <td>{key}</td>)}
</tr>
</thead>
<tbody >
{vendors.slice(scroll.firstNode, scroll.lastNode).map((item) => (
<tr style={{ height: rowHeight }} key={item.id}>
{vendorKeys.map((key) => <td><div className="data">{item[key]}</div></td>)}
</tr>
))}
</tbody>
</table>
</div>
</div>
);
}
// const rootElement = document.getElementById("root");
// ReactDOM.render(<App />, rootElement);
const root = ReactDOM.createRoot(
document.getElementById('root')
);
root.render(
<App />
);
```
styles.css
```
* {
padding: 0;
margin: 0
}
.table-fixed-head thead th{
background-color: white;
}
.row {
line-height: 20px;

max-width: 200px;

}
.data{
width: 150px;
white-space: nowrap;
overflow: hidden;
margin-right: 20px;
}
```
I have spent 1.5 day trying to find the reason why the table bounces on scroll in React 18 without result.
BTW, overscroll-behaviour: none doesn`t work.

I want to create a login system in the react native app using firebase auth. In there a i have used ValidateJS for the frontend validation. But i am stuck with how to implement the confirm password field. I am not able to validate that the Confirm Password field is same the the Password Field.
I have pasted the codes below.
**Signup.js**
```js
export default function Signup({ navigation }) {
const [isLoading, setIsLoading] = useState(false);
const [formState, dispatchFormState] = useReducer(reducer, initialState);
const inputChangedHandler = useCallback(
(inputId, inputValue) => {
const result = validateInput(inputId, inputValue);
dispatchFormState({ inputId, validationResult: result, inputValue });
},
[dispatchFormState]
);
const signupHandler = () => {
/// code
};
return (
<SafeAreaProvider>
<View>
<Image source={appIcon} />
<Text> Getting Started</Text>
<Text> Create an account to continue !</Text>
<View>
<Inputs
id="username"
placeholder="Username"
errorText={formState.inputValidities["username"]}
onInputChanged={inputChangedHandler}
/>
<Inputs
id="email"
placeholder="Enter your email"
errorText={formState.inputValidities["email"]}
onInputChanged={inputChangedHandler}
/>
<InputsPassword
id="password"
placeholder="Password"
errorText={formState.inputValidities["password"]}
onInputChanged={inputChangedHandler}
/>
<InputsPassword
id="ConfirmPassword"
placeholder="ConfirmPassword"
errorText={formState.inputValidities["password"]}
onInputChanged={inputChangedHandler}
/>
</View>
<Buttons
title="SIGN UP"
onPress={signupHandler}
isLoading={isLoading}
/>
<View>
<Text>Already have an account?</Text>
<TouchableOpacity
onPress={() => {
navigation.push("Login");
}}>
<Text>Log In</Text>
</TouchableOpacity>
</View>
<StatusBar style="auto" />
</View>
</SafeAreaProvider>
);
}
```
**Validate.js**
```js
import { validate } from "validate.js";
export const validateString = (id, value) => {
const constraints = {
presence: {
allowEmpty: false,
},
};
if (value !== "") {
constraints.format = {
pattern: ".+",
flags: "i",
msg: "Value can't be blank.",
};
}
const validationResult = validate({ [id]: value }, { [id]: constraints });
return validationResult && validationResult[id];
};
export const validateEmail = (id, value) => {
const constraints = {
presence: {
allowEmpty: false,
},
};
if (value !== "") {
constraints.email = true;
}
const validationResult = validate({ [id]: value }, { [id]: constraints });
return validationResult && validationResult[id];
};
export const validatePassword = (id, value) => {
const constraints = {
presence: {
allowEmpty: false,
},
};
if (value !== "") {
constraints.length = {
minimum: 6,
msg: "must be atleast 6 characters",
};
}
const validationResult = validate({ [id]: value }, { [id]: constraints });
return validationResult && validationResult[id];
};
```
**formActions.js**
```js
import {
validateConfirmPassword,
validateEmail,
validatePassword,
validateString,
} from "../validation.js";
export const validateInput = (inputId, inputValue) => {
if (inputId === "username") {
return validateString(inputId, inputValue);
}
if (inputId === "email") {
return validateEmail(inputId, inputValue);
}
if (inputId === "password" || inputId === "confirmPassword") {
return validatePassword(inputId, inputValue);
}
};
```
**formReducer.js**
```js
export const reducer = (state, action) => {
const { validationResult, inputId, inputValue } = action;
const updatedValues = {
...state.inputValues,
[inputId]: inputValue,
};
const updatedValidities = {
...state.inputValidities,
[inputId]: validationResult,
};
let updatedFormIsValid = true;
for (const key in updatedValidities) {
if (updatedValidities[key] !== undefined) {
updatedFormIsValid = false;
break;
}
}
return {
inputValues: updatedValues,
inputValidities: updatedValidities,
formIsValid: updatedFormIsValid,
};
};

A better solution would be to call this function after scanning and before calling another activity :
public void stopEmdkManager(){
if (this.emdkManager != null) {
this.emdkManager.release();
this.emdkManager = null;
}
} |
This is what I want to achieve:
I have endpoints in the form `/entity1/<id>/entity2/<id>/stuff`, i.e.:
```
let route = warp::path("entity1")
.and(warp::path::param::<u64>())
.and(warp::path("entity2"))
.and(warp::path::param::<u64>())
.and(warp::path("stuff"))
.and(warp::path::end())
.and(with_auth(db.clone())) // Authenticates user using Authorization header
.and_then(handler_function);
```
I have several similar endpoints that load entity2 from the database, reject the request if it does not match to entity1, and do then stuff with the loaded entity. My idea is to create a filter that loads the entity from the database and passes it to the handler function (and does some validation, eventually rejecting the request) with something like `.and(with_entity2(db.clone()))` and
```
pub fn with_entity2(db: &Db) -> impl Filter<Extract = (Entity2,), Error = warp::Rejection> + Clone {
// Get path params here?
}
```
I guess I could use `FullPath`, but would need to parse it myself.
Is it possible to get the path params? Or is there a better option? I wouldn't need the extracted params anymore, but I don't want to do database queries before the user is authenticated and the whole path matches. |

From the [JSON Schema reference][1], regarding to array validation:
> While the `items` schema must be valid for every item in the array, the `contains` schema only needs to validate against one or more items in the array.
There are some examples on the docs where you can see that the `items` validation restricts the array to have all values compliant with the rule. But in the case of `contains`, only one *valid* value is enough to make it compliant.
This explains why the errors can be detailed in the `items` particular case.

**I have 2 clusters,both publicly accessible,same security groups,but in different public subnets,I can connect to one cluster from local, but not the other.
Tried connecting via cluster ip, tried adding my ip as well as 0.0.0.0/0 to security groups, rebooted cluster after allowing public access, nothing helped.**
Edit:
Solution:
When configuring cluster, I get to select the subnet group, and I chose the default one, which was a mixture of public and private subnets. So AWS randomly chose a subnet from it for my cluster, which was a private one. that is why I haven't been able to connect to it via local. |
You can see the difference if and only if the function actually needs to do something, either to catch the exception or to call a destructor, when an execption is thrown.
https://godbolt.org/z/PrqEeKrqP
Here's an example.
If every function **called** in a block is marked as `noexcept`, or if the **calling** function itself is `noexcept`, the compiler can safely omit all exception handling logic. Otherwise, a hidden `catch` block is generated to call destructors.
Note that I compile the example code with `-shared` flag to avoid inlining. |
I don't know enough about the default trigger to comment on #1
To answer #2
I would consider using an event grid event. This way there's no polling and events are received only when the blob is created. So setting up a new function against an existing storage container would imply an invocation only for new blobs that are subsequently added.
Noting that event grid guarantees "at least once delivery" (due to possibility of transient faults) so you do need to account for that. REF https://learn.microsoft.com/en-us/azure/azure-functions/storage-considerations?tabs=azure-cli#trigger-on-a-blob-container |
Allow me to start with a basic disclaimer: I always use VMs to run more complex server-like applications. In this example I run minikube on a VM, as I want to play around with Kubernetes a bit. Once I'm done, I kill the VM, or back it up somewhere external to get rid of the stuff quickly. Installing this on my local OS is not a viable option to me. Now to the question/issue I want to resolve.
I have a small Spring Boot Service, nothing worth mentioning. I want to deploy that service into a Pod. Following online documentations and tutorials, I have setup my VM on Debian 12 with Docker, Helm and Minikube. I used a kubernetes/helm plugin for my IDE to have all the necessary config files generated, and followed a simple onboarding tutorial to get an idea of how the basics work. My issue arises with my desire to have Minikube on a VM, instead of having it on the base client. I fail to build the docker image on the VM through Maven.
What works:
- I can build the .jar-File
- I can copy the dockerfile and the .jar-File to the VM using Maven-Antrun-Plugin with SCP
- I can build the image manually on the VM using "docker build -t name ."
- I can use SSHEXEC to create a file through the touch command or a directory through mkdir
What doesn't work:
- Using the antrun plugin for SSHEXEC to execute above command with the proper path, results in the proper terminal feedback, but not in a created image
- I tested the same through a shell-script "buildImage.sh", which runs the command in the proper folder, and have SSHEXEC just run the script, yielding the same results
I use following execution (removed personal info) to run the sshexec
```
<execution>
<id>builddocker</id>
<phase>pre-integration-test</phase>
<goals>
<goal>run</goal>
</goals>
<configuration>
<target>
<sshexec host="xxx" username="xxx" password="xxx"
failonerror="true" trust="true" timeout="120000" usepty="true"
command="docker build -t xxx ${kubernetes.image.path}"/>
</target>
</configuration>
</execution>
```
This is the first setup. The setup where I execute the shell-script is a bit more convoluted, but works the same. The only difference, why I tested it, is that the docker command is executed in the same working directory, where the dockerfile is located.
My original hypothesis was that SSHEXEC closes the connection before the command finishes. The existence of the docker feedback in the execution console disproves this though. There are no error messages from docker. Docker finishes with "Writing image sha256:" and "naming to docker.io/library/xxx" But as soon as I **docker images ls** or **minikube images ls** the image isn't there. I also tripple checked that maven uses the same user as I use on my ssh terminal to check the results.
Right now I'm a bit out of ideas, so I thought I'll open a question here to see if someone else has an idea. I also never rule out that I missed something really silly :)
PS: If there is another approach to deploy the java/docker-stuff on the VM (meaning better than maven) I'm happy to hear it too. Maven is just "the most obvious answer" when I think of automatic builds in Java. |

I'm currently trying to deploy a Next.js app on GitHub Pages using GitHub Actions, but I get a page 404 error even after it successfully deploys. I've looked around a bunch of similarly named questions and am having trouble figuring this out.

I read in https://stackoverflow.com/questions/58039214/next-js-pages-end-in-404-on-production-build that perhaps it has something to do with having sub-folders inside the `pages` folder, but I'm not sure how to fix that as I wasn't able to get it to work without sub-foldering `page.js` files for each page.
EDIT: Here is my `next.config.js` file:
```
/** @type {import('next').NextConfig} */
const nextConfig = {
basePath: '/pages',
output: 'export',
}
module.exports = nextConfig
