I want to test my react project array
```ts
// this method is in the utils.ts
export const platform = (
navigator.userAgentData?.platform || navigator.platform
).toLowerCase()
export const keyboardPlayerShortcutsData = [
{
name: 'play/pause',
shortcut: platform.startsWith('mac') ? `⌘ + p` : 'Ctrl + p',
}
]
```
```ts
it('should generate correct keyboard player shortcuts data (mac)', () => {
// need to mock "import { platfrom } from './utils'"
expect(keyboardPlayerShortcutsData).toEqual([
{
name: 'play/pause',
shortcut: '⌘ + p',
},
])
const shortcutElement = screen.getByText('⌘ + p')
expect(shortcutElement).toBeInTheDocument()
})
it('should generate correct keyboard player shortcuts data (win)', () => {
// need to mock "import { platfrom } from './utils'"
expect(keyboardPlayerShortcutsData).toEqual([
{
name: 'play/pause',
shortcut: 'ctrl + p',
},
])
const shortcutElement = screen.getByText('ctrl + p')
expect(shortcutElement).toBeInTheDocument()
})
```
I use `vi.mock('./utils', () => ({ platform: 'mac' }))` in each test, but `vi.mock` will hoist to the top, so the test will fail.
I also tried, but it also not work
```ts
import { platform } from './utils'
describe('EditKeyboardShortcutSheet', () => {
vi.mock('./utils', () => ({
platform: 'MacIntel'.toLowerCase(),
}))
afterEach(() => {
vi.clearAllMocks()
})
it('should generate correct keyboard player shortcuts data (mac)', () => {
expect(keyboardPlayerShortcutsData).toEqual([
{
name: 'play/pause',
shortcut: '⌘ + p',
},
])
})
it('should generate correct keyboard player shortcuts data (win)', () => {
// ref: https://github.com/vitest-dev/vitest/discussions/4328
// got an ts error: Property 'mockReturnValue' does not exist on type 'string'.
vi.mocked(platform).mockReturnValue('Windows')
expect(keyboardPlayerShortcutsData).toEqual([
{
name: 'play/pause',
shortcut: 'ctrl + p',
},
])
})
})

I'm trying to send a delete http request but it does not work. Delete request should be send when clicking a button. Please help.
<!-- begin snippet: js hide: false console: true babel: false -->
<!-- language: lang-js -->
const ondeletehandle = async() => {
const response = await fetch('/api/notebook/' + notebooks._id, {
method: 'DELETE'
})
const json = await response.json()
if (response.ok) {
dispatch({

payload: json
})
console.log(notebooks)
}
if (!response.ok) {
console.log("error")
}
}
i tried looking up for delete header but that didn't work

I am trying to understand an issue that arose following the news regarding the new format of the Champions League.
As some of you may know, the new format consists of `n=36` teams, divided into `p=4` pots. Each team will face `o=2` teams from each pot, resulting in a total of `p*o=8` matches, with one match played away and one at home for each pot.
Update
---
This is my attempt as now. For low values of N_TEAMS the script works in a reasonable time, for larger it can stuck. It surely need some optimization, what can I optimize?
PS:the biggest issue is the limitation on the number of matches to be played home vs away (if that control is removed, everything is really fast!)
```
<?php
const N_TEAMS = 36;

const M_PER_POT = 2;

Creating a Google Login-In Extension for a personal project so I've set up funtionality that allows me to log in to the extension with my Google account and it works. I'm using an initial HTML file called "popup.html" to hold the logic of Google's Authentication by calling "popup.js" as the backend script, displaying a "Waiting for Log-in" message, and then setting that <div> attribute to display the contents of another HTML file called "authorized.html" after succesful sign-in by setting its contents as the innerHTML property of "popup.html". The issue is that "authorization.html" own script "authorized.js" will not print anything to either my console nor will it even throw an error on the console despite the other contents of "authorized.html" succefully being displayed. Only the relevant parts of my code are below but I'd like to know why I'm having this issue and how to circumvent it. Thank you
popup.html:
```
<!DOCTYPE html>
<html>
<head>
<title>Google OAuth Sign-In</title>
<script src="popup.js"></script>
</head>
<body>
<div id="Sign-In TempUI" class="content-body">Waiting for Google Sign-In</div >
</body>
</html>
```
popup.html:
```
console.log('popup.js loaded');
document.addEventListener('DOMContentLoaded', function () {
const NewGUI = document.getElementById('Sign-In TempUI');
chrome.identity.getAuthToken({ interactive: true }, function (token) {
if (chrome.runtime.lastError) {
console.error(chrome.runtime.lastError.message);
return;
}
console.log('Token acquired:', token);
loadAuthorizedUI(token);
});
function loadAuthorizedUI(token) {
console.log('Debug:', token);
fetch('authorized.html')
.then(response => response.text())
.then(html => {
console.log('HTML content:', html);
NewGUI.innerHTML = html;
})
.catch(error => console.error('Error fetching or processing HTML:', error));
}
});
```
authorized.html:
```
<!-- Page Displayed after recieving token from OAuthetication. Should display GUI for Email handling -->
<!DOCTYPE html>
<html>
<head>
<title>Authorized UI</title>
</head>
<body>
<h1>Welcome! You are now authorized.</h1>
<ul id="emailList">
</ul>
<script src="authorized.js"></script>
<div>Hit end</div>
</body>
</html>
```
authorized.js:
```
//throw new Error('This is a test error from authorized.js');
console.log('authorized.js loaded');
```
I'm using Chrome DevTool to debug, while also including popup debugger so before I was starting another document.addEventListener('DOMContentLoaded', function ()) and then trying to replace the contents of emailList after trying to get its element by Id, but it wont even open authorized.js. Console.log doesnt print anything and the exception doesnt actually display anything on the console. However when I move the authorized.js script to popup.html, it'll suddenly display albiet errors. My biggest confusion is that "<h1>Welcome! You are now authorized.<h1>" and "<div>Hit end</div>" will display on my GUI but the script wont even print, as if its skipping it |

[enter image description here][1]Suppose A is a symmetric matrix whose SVD is A= USV^T, and let B = U\sqrt{S}V^T, then B^2 should be equal to A.
But when I implemented it using tensorflow, B^2 and A does not match. Highly appreciated if you could give some advice!

I tried manually adding older versions of the package in question but I could not find a suitable solution so far. Deleting node_modules or package.json and then running `npm i`again also did nothing to change the outcome.
Has anyone also had the same problem?
I had this problem after I ran `npm update`, then I fixed the issues due to some changes mentioned in the docs. But the main issue is, that previously normally functioning features are not working despite no change inside the docs suggesting I did something wrong.
I use `next 14.1.0`, `next-sanity 8.5.0` and `sanity 3.36.2` |
I am getting an error in `R` in Windows 10 about finding a directory while trying to install a package from GitHub*. Trying to troubleshoot this error led me to a few observations.
For example, both Windows Explorer and my browser can find `C:/PROGRA~1`, but only my browser can find `C:/PROGRA~1/R`, where `R` is installed. The specific Windows Explorer error is:
Windows can't find 'C:/PROGRA~1/R'. Check the spelling and try again.
Yet, Windows Explorer can find `C:/Program Files/R` no problem. And the error above is the same with `C:/PROGRA~1/Adobe`, `C:/PROGRA~1/Google`, or any other. Even more interesting, Windows Explorer can't even find the raw program files path as long as we add a simple slash at the end! So `C:/PROGRA~1/` will output a similar error.
So can anyone explain to me why Windows Explorer is not able to find `C:/PROGRA~1/R` or `C:/PROGRA~1/`? Is this normal/expected? If I solve this, I can probably resolve my `R` error too. Thanks.
*Here is the full original error in `R`:
Error: Failed to install 'package' from GitHub:
create process 'C:/PROGRA~1/R/R-40~1.3/bin/x64/Rcmd.exe' (system error 267, The directory name is invalid.
) @win/processx.c:1040 (processx_exec)
Edit: My investigation revealed that it might be related to the direction of slashes... So for instance, `C:/PROGRA~1\R` (or even `C:/PROGRA~1\`) works in Windows Explorer, but only as long as the second slash is a backslash... Can this be of any help in resolving this issue? Doesn't seem like `R` wants to put that second slash as backslash...
Edit 2: My answer below was deleted so here it is again:
> The issue was with the processx package and the development version has since received a fix (in version v3.5.3). Please see the following discussion for more info: https://github.com/r-lib/processx/issues/313 |

In your original post at first picture i can see a lot of stencils which are opened in separated windows as Read-Only [RO]…
It is not ShapeSheet windows!!!
I have not documents with same issue and I create one with code
Option Base 1
Sub Prepare()
Dim pth(3) As String, curpath As String, i As Integer
pth(1) = "C:\My Shapes\19_inch_Rack_flexible_RU.vss"
pth(2) = "C:\My Shapes\Favorites.vssx"
pth(3) = "C:\My Shapes\GOST_R_21.1101-2013.vss"
For i = LBound(pth) To UBound(pth)
curpath = pth(i)
Documents.OpenEx curpath, visOpenRO ' open stencil in new window as read-only
Next
ActiveDocument.DocumentSheet.OpenSheetWindow ' add Document ShapeSheet window
End Sub
At my side next code close all windows if type of window is not **Drawing window**. Please read more about [VisWinTypes enumeration (Visio)](https://learn.microsoft.com/en-us/office/vba/api/visio.viswintypes)!
Next code can close all non-drawing windows
Sub Test()
Dim va As Application, vw As Window
Set va = Application
For Each vw In va.Windows
Debug.Print vw.Caption, vw.Type, vw.SubType
If Not vw.Type = visDrawing Then vw.Close ' visDrawing = 1 Python dont know Visio internal constants
Next
ActiveDocument.ContainsWorkspaceEx = False ' prevent save document workspace (a lot of RO-opened stencils)
ActiveDocument.Save
End Sub
`ActiveDocument.ContainsWorkspaceEx = False` this line prevent save workspace (all RO stencils). Please check this article [Document.ContainsWorkspaceEx property (Visio)](https://learn.microsoft.com/en-us/office/vba/api/visio.document.containsworkspaceex).
~~Right now I have not Python environment, I try find it later…~~
I try this code with Jupyter Notebook, it works at my side…
import win32com.client
app = win32com.client.Dispatch('Visio.Application')
app.Visible = True
for i in range(app.windows.count,1,-1):
vw = app.windows(i)
if vw.Type!=1:
vw.close
app.ActiveDocument.ContainsWorkspaceEx = False
app.ActiveDocument.Save |
So I am basically very new to Assembly in general. I was trying to write this simple code where I need to sort numbers in an ascending order from source data and rewrite it into destination data.
and whenever I run it, it shows: executables selected for download on to the following processors doesn't exist...
here is the code, maybe something wrong with it:
```
.global _start
_start:
ldr r0, =Input_data // load the input data into r0
ldr r1, =Output_data // load the output data into r1
mov r2, #32 // word is 32
first_loop:
ldr r3, =Input_data // load the input data into r3
ldr r4, [r3], #4 // load the 1st elem of input data into r4
mov r5, r0 // move to the second loop
second_loop:
ldr r6, [r1] // load the value of output data into r6
cmp r4, r6 // compare the current element eith the value in output data
ble skip_swap // if the current element is less than or equal, continue
// swap the elements:
str r6, [r1]
str r4, [r1, #4]
skip_swap:
// move to the next elem in output data
add r1, r1, #4
// decrement by one remaining elements (r2 was 32)
subs r2, r2, #1
// check if we have reached the end of input_data
cmp r3, r0
// if not, continue to the second loop
bne second_loop
// if the first loop counter is not zero, continue to the first loop
subs r2, r2, #1
bne first_loop
// exit
mov r7, #0x1
svc 0 // software interrupt
.data
.align 4
Input_data: .word 2, 0, -7, -1, 3, 8, -4, 10
.word -9, -16, 15, 13, 1, 4, -3, 14
.word -8, -10, -15, 6, -13, -5, 9, 12
.word -11, -14, -6, 11, 5, 7, -2, -12
// should list the sorted integers of all 32 input data
// like if saying: .space 32
Output_data: .word 0, 0, 0, 0, 0, 0, 0, 0
.word 0, 0, 0, 0, 0, 0, 0, 0
.word 0, 0, 0, 0, 0, 0, 0, 0
.word 0, 0, 0, 0, 0, 0, 0, 0

We have couple of applications which are desktop(PC) , Mobile applications, so planned to create unique test automation framework in java
we have created a framework to support both desktop and mobile platforms using below tech stack
Selenium webdriver, appium, java client, testNG, allure , java 17
but i am facing issues while running tests in parallel , only one tests run on desktop browser the other tests open in mobile but it sits in idle state without running tests
baseTests.java
Boolean isMobile= (Boolean) deviceInfo.get("isMobile");
Boolean isHeadLess = (Boolean) deviceInfo.get("isHeadless");
if (Objects.isNull(DriverManager.getDriver())) {
if (isMobile) {
serverManager.startServer();
deviceName = deviceInfo.getString("devicename");
String avd = deviceInfo.getString("avd");
String udid = deviceInfo.getString("udid");
String platformVersion = deviceInfo.getString("platformVersion");
Boolean isEmulator = (Boolean) deviceInfo.get("isEmulator");
URL url = new ServerManager().getServer().getUrl();
RemoteWebDriver driver=DriverFactory.initializeMobileDriver(MobilePlatformName.valueOf(platformType.toUpperCase()), deviceName, udid, isEmulator, isHeadLess,browserName, url);
} else {
RemoteWebDriver driver=DriverFactory.initializeWebDriver(WebBrowserName.valueOf(browserName.toUpperCase()), isHeadLess);
}
}
here i am using 'RemoteWebDriver' to refer both selenium webdriver and appium driver
DriverManager.java
private static final ThreadLocal<RemoteWebDriver> threadLocalDriver = new ThreadLocal<>();
public static synchronized RemoteWebDriver getDriver() {
return threadLocalDriver.get();
}
public static synchronized void setAppiumDriver(RemoteWebDriver driver) {
if (Objects.nonNull(driver)) {
threadLocalDriver.set(driver);
}
}
public static synchronized void unload() {
threadLocalDriver.remove();
}
Testsclass.java
public class SearchTest extends BaseTest{
public test(){
driver= DriverManager.getDriver();
if (PlatformUtils.isMobile(driver)) {
googleSearch()
Else{
googleSearch()
}
}
}
If I use
if (PlatformUtils.isMobile(driver)) {
googleSearch()
Else{
googleSearch()
}
This way tests run on both the platforms but
If I use simply
googleSearch()
Then both desktop and mobile browser will open but only one test run on desktop but mobile tests just stay idle without moving
Is it right the way using of remotewedriver to refer both selenium web drover and appium driver ?
If I use above way so that I can use common driver and common code to tests ,instead of using different appium driver and selenium driver separately
Can someone help me to get the correct approach to handle both mobile and desktop(pc) ?

[Per my top comment], building with `-Wall -O0 -g -fsanitize=address`, a few issues ...
1. With `-Wall`, arguments `col` and `row` are `char` and compiler complains about that (converted to `int`)
1. `row` and `col` are unitialized (in `main`) but the _values_ are never used by `computerMove` or `UserMove` (set to zero to eliminate warning). They do _not_ need to be arguments.
1. After fixing the warnings (which one should _always_ do), the address sanitizer is detecting a fault.
----------
With a board size of `8` and computer with `B`, in `computerMove`, the sanitizer complains about the `if`:
```
for (int i = 0; i < counter; i++) {
for (int j = 0; j < n; j++) {
dbgprt("i=%d j=%d tracker=%d\n",i,j,tracker);
if ((movesrow[duplicates[i]] < movesrow[duplicates[i + j]]) &&
movescol[duplicates[i]] < movescol[duplicates[i + j]]) {
rowtemp = movesrow[duplicates[i]];
coltemp = movescol[duplicates[i]];
}
else {
rowtemp = movesrow[duplicates[i + j]];
coltemp = movescol[duplicates[i + j]];
}
}
}
```
The debug `printf` I added shows:
```
i=0 j=0 tracker=4
i=0 j=1 tracker=4
i=0 j=2 tracker=4
i=0 j=3 tracker=4
i=0 j=4 tracker=4
```
The array `duplicates` is of dimension `tracker` (which is 4), so `i + j` is becoming too large and overflows `duplicates`. This is UB (undefined behavior).

I'm programming a simple 'game' that is just a block that can jump around. I placed a wall, but now the character phases through when moving to the right, but the collision works when going to the right.
The collision in question:
```
function willImpactMovingRight(a, b){
var docA = document.getElementById(a);
var docB = document.getElementById(b[0]);
for(var i=0;i<b.length;i++){
docB = document.getElementById(b[i]);
if((docA.offsetTop>docB.offsetTop&&docA.offsetTop<docB.offsetTop+docB.offsetHeight)||(docA.offsetTop+docA.offsetHeight>docB.offsetTop&&docA.offsetTop+docA.offsetHeight<docB.offsetTop+docB.offsetHeight)){//vertical check, not broken
if(docA.offsetLeft>docB.offsetWidth+docB.offsetLeft-runSpeed){//also fine
//below this is the problem
if(docA.offsetLeft+docA.offsetWidth+runSpeed<=docB.offsetLeft){
CUBE.textContent = "WIMR";
return docB.offsetLeft-docA.offsetWidth;
}
//all syntax is fine but the if statement never returns as true.
}
}
}
return false;
}
```
it looks like a lot, but the only problem is the last if statement. Even when the condition is true, it still returns false. Any idea why?

I am rendering different sections in my dashboard using a nested Route.
The problem is when I navigate between sections (using react-router-dom `Link`) it unmounts the section so when I go back it has to re-load and re-render the section.
Here is how i'm setting the routes
```
<Routes>
{(!user.loaded && userWasLoaded) || (user.loaded && user?.user) ? (
<Route path='/' element={<DashboardPage />}>
<Route index element={<Feed />} />
<Route path='/configuration' element={<Listeners />} />
<Route path='/team' element={<Team />} />
{user?.user?.isAdmin && (
<Route path='/admin' element={<Admin />} />
)}
</Route>
) : (
<Route path='/' element={<LoginPage />} />
)}
<Route path='/login' element={<LoginPage />} />
<Route path='/pricing' element={<Pricing />} />
<Route path='/privacy' element={<PrivacyPolicyPage />} />
<Route path='*' element={<Navigate to='/' />} />
</Routes>
```
and here is how i'm getting data in my pages:
```
const Team = () => {
const [plan, setPlan] = React.useState(null);
useEffect(() => {
API.getMyPlan().then((data) => setPlan(data));
}, []);
```
I am expecting react and react-router-dom to NOT unmount each section whenever I navigate between pages.

I believe in this case you should not use the entry API anyway - even without considering this issue.
This is because the entry API, in order to be able to insert the key if missing, needs an owned key. For you that means that you cannot lookup with `&str`, you must call `to_string()` on it - and that means an allocation, which is a bigger cost than a second lookup, and assuming (as I understand) that most of the times the pattern is already registered, the cost of the allocation will dwarf the cost of the double lookup.
So the best solution for you is to use a simple structure:
```rust
fn register_pattern(&mut self, pattern: &str) {
if !self.regex_registry.contains(pattern) {
let asc = self.parse_locale_pattern(pattern.to_string(), ParseLocale::Ascii);
let jap = self.parse_locale_pattern(pattern.to_string(), ParseLocale::Japanese);
let parse_localized_regex = ...expression involving asc, jap...;
self.regex_registry.insert(pattern.to_string(), ParseLocalized::new(asc, jap));
}
}

`getTimezoneOffset()` returns wrong timezone.
I'm in Kyiv and my local time is 10:07.
**Kyiv time confirmed**:
```
> new Date().toLocaleString('en-GB', {timeZone: 'Europe/Kyiv' });
// '31/03/2024, 10:07:28'
```
Yesterday Kyiv was on winter time GMT+3, but today winter time is off and Kyiv is on GMT+2.
**2 hour difference confirmed**:
```
> new Date().toLocaleString('en-GB', {timeZone: 'Europe/London' });
// '31/03/2024, 08:07:07'
```
So, getTimezoneOffset() suppose to return -120, right? No.
```
> new Date().getTimezoneOffset()
// -180
```
I switched local TZ on my PC to Paris and got `-120` though Paris is GMT+1 and `-60` was expected. So it seems `getTimezoneOffset()` is one hour off for all the TZs.
I can see that people struggled with `getTimezoneOffset()` before and some workarounds are out there, but the question stands: Why `getTimezoneOffset()` returns wrong result at the first place? |
Why new Date.getTimezoneOffset() returns wrong result? |

I´m new to stackoverflow and i´ve just been into software testing and this whole world for about a year but I am currently developing myself as a QA in a startup and i´ve been automating my test plan using Selenium with Python and Pytest.
Currently I have 359 tests that run perfectly on my computer when using the GUI but now my team has established a virtual machine to run them twice a day for what they have to run in headless mode and most of them fail.
When I run them headless on my computer they also fail, I don´t know why because it should work identically as far as i´m concerned.
I´ll be super gratefull if you guys can help me in making the necessary changes to make the automated suite run well in headless mode as well.
Thanks!
I just run them headless expecting them to pass as always but that didn´t go as I expected.
This is a bit of the code i´m using:
```python
class Test_CON_02_Coupons(unittest.TestCase):
def setUp(self):
chrome_options = Options()
chrome_options.add_argument("--headless")
chrome_options.add_argument("--no-sandbox")
self.driver = webdriver.Chrome(options=chrome_options)
self.driver.implicitly_wait(60)
self.driver.maximize_window()
self.vars = {}
self.driver.get(CON_SELFSERVICE_URL)

Is there any way to tell Notepad please remove the following
[DOCUMENT](https://i.stack.imgur.com/Ukr0X.jpg)
Remove all the empty characters after the last , sign. I know I can tell please replace , with empty but the problem is I have many , that hast to stay in the file.
I just need notepad to remove EVERYTHING including that last , sign after the last , sign in the document.
For example
14.56364,46.02230,1,80,1**,216,Golovec**
I need that to be
14.56364,46.02230,1,80
With no empty spaces after that or that last , sign.
The problem is sometimes some lines have more than one empty characters after the last , sign.
This does not help **.{1}$**
The problem is the Python script I have and is very sensitive to any kind of extra signs of characters after the last , sign.
Thank you
I tried all the .{1}$
replace empty spaces...works but needs to be repeated since some lines have more than one empty charatcter. |

The code below uses a **background callback** (dash) to retrieve a value.
Every 3 seconds, `update_event(event, shared_value)` sets an `event` and define a `value`. In parallel, `listening_process(set_progress)` waits for the `event`.
This seems to work nicely and the waiting time is low (say a few seconds). When the waiting time is below 1 second (say 500ms), `listening_process(set_progress)` is missing values.
Is there a way for the **background callback** to refresh faster ?
It looks like the server updates with a delay of a few hundred of ms, independently of the rate at which I set the `event`.
I could have used a `dcc.interval` but wanted to prevent polling.

I have created a custom SAML application in the Google Admin panel for my workspace account to allow users to login via SSO to an application using their Google Workspace credentials. Currently only users of my organisation can login to this application. I want to make it so that users of an external organisation can also login to this application using their Google Workspace credentials using SSO. How do I do this?
Tried:
I have created a Google Group and all users who should have access to this application (both internal and external organisation users) and turned on access to this Google Group in the access settings of the custom SAML app.
Expected:
Both internal and external users should be able to login to the application.
Result:
Only internal users are able to login to the application using their credentials. |

local Backpack = game:GetService("ReplicatedStorage"):Waitforchild("Backpack")
local Player = game:GetService("Players").localplayer
Player.Character.Respawned:Connect(function(Character)
local clone = Backpack:clone(Character.Torso)

### Summary
There is a difference between `any` in type parameter and `any` in regular function parameter. Your case is the former one for generics. So you need to instantiate `T`(decide `T`'s concrete type) first when assigning it to the concrete variables
Ref. https://stackoverflow.com/questions/71628061/difference-between-any-interface-as-constraint-vs-type-of-argument
### In detail
It's because in `GetAllProducts`, type `T` is not decided yet. So it is impossible to assign `[]models.Products` to `T`.
```golang
func (db *DbConnection[T]) GetAllProducts() {
var re []models.Products
re, _ = db.GetAll()
}
```
But you can assign `models.Products` to `T` if `T` is decided as `models.Products`, like this.
```golang
db := DbConnection[models.Products]{}
var re []models.Products
re, _ = db.GetAll()
```
I reproduce your problem in the simplified version(https://go.dev/play/p/GHkDThFLOKG). You can find the same error `GetAllProducts()` but in the main code, it works. |
You may try-
=HSTACK(
TOROW(FILTER($A$2:$A$7;BYROW($B$2:$M$7;LAMBDA(rw;INDEX(OR(rw=H13)))));3);
TOROW(FILTER($B$1:$M$1;BYCOL($B$2:$M$7;LAMBDA(col;INDEX(OR(col=H13)))));3)
)

The following code will add 3000 to 4000 documents of various sizes to a Firebird Blob field before running out of memory. I believe I have freed the streams I create, but I may not be doing it correctly. Streams are a new tool in my toolbox. Can anyone spot what I'm doing wrong?
```
procedure TfrmMigration.Button1Click(Sender: TObject);
var
DocFile: string;
Blob: TStream;
fs: TFileStream;
begin
with DM.qImageList do
begin
close;
SQL.Text := ImgListSQL;
open;
First;
while not eof do
begin
{ Ignore if previously done.}
if (FieldByName('Document_Files').IsNull) then
begin
DocFile := Trim(gsDocumentPath + '\' + FieldByName('ImageName').asString);
if FileExists(DocFile) then
begin
edit;
Blob := CreateBlobStream(FieldByName('Document_Files'), bmWrite);
try
Blob.Seek(0, soFromBeginning);
fs := TFileStream.Create(DocFile, fmOpenRead or fmShareDenyWrite);
try
Blob.CopyFrom(fs, fs.Size);
finally
fs.free;
end;
finally
Blob.free;
end;

Out of memory while adding documents to a Firebird BLOB field with Delphi |
|delphi|blob|streaming|firebird| |
> while(true);
Your code probably can't detect the GPS for some reason, so it go into this infinite `while(true)` loop. For ESP8266, the watchdog timer running in the background need to be "feed" regularly, this infinite loop choke the "dog" to death, change the line to the follow would allow the watchdog to "breath".
```cpp
while(true) { delay(1); }
```
This will solve the reboot problem, you still need to deal with why the GPS is not working, so check the connection and test it outdoor with clear view of open sky. |

The zip file is uploaded to the storage account, is downloadable and has the correct structure (or so I think). Function App is created as well, however when I scroll down to see the functions, it tells me there was an error loading functions: `Encountered an error (ServiceUnavailable) from host runtime.` It's probably some configuration error, but I just can't see it. Also I went to the advanced tools tab and in wwwroot there's only one file named `run_from_package_failure.log`. Its contents are:

important: I don't have a deep understanding of malloc so try to put things as simple as possible
Greetings, I want to create a dynamic array of strings (using malloc) and then print those strings out (for starters).
That's what I have
```
int main(){
char **namesofcolumns = malloc(4 * sizeof(char*));
for(int i = 0; i < 4; i++){
namesofcolumns[i] = malloc(20 * sizeof(char));
}
int count = 1;
for(int i = 0; i < 4; i++){
printf("Enter %d column name\n", count);
scanf("%s", namesofcolumns[i]);
count++;
}
```
I probably have errors here already. How do I print entered strings out? |

Trying to create a dialog class which will contain a QTableView widget, all is good, information gets inserted, but i cannot understand why pycharm show the error: "Unresolved attribute reference 'setModel' for class 'Dialog'"
all class code here:
```
from PyQt5.QtGui import QStandardItemModel, QStandardItem
from PyQt5.QtWidgets import QDialog, QTableView
from PyQt5.uic import loadUi
class Dialog(QDialog):
def __init__(self):
super(Dialog, self).__init__()
loadUi("dialog.ui", self)
self.table = self.findChild(QTableView, "tableView")
def fill_table(self, data):
column_names = ["full_name", "mail", "age", "phone_number"]
model = QStandardItemModel(1, 4)
model.setHorizontalHeaderLabels(column_names)
for col_idx in range(4):
item = QStandardItem(data[col_idx])
model.setItem(0, col_idx, item)
self.table.setModel(model)
```
explain me what's going on and suggest solutions to the problem.

I have a [MERN][1] stack application which I deployed to Render (server side as web service and front end as static). \
In my application, I have a profile where users can upload avatar image. I store an image as a URL string in my MongoDB [Atlas_][2] in User model.
Images are saved on the server in uploads folder. The image upload works fine and image fetches successfully, from both deployment and local environment. But after a while I start to get Internal server error when fetching same image.
What is the reason and how to solve this issue? Or is there a better way of storing images in MongoDB Atlas without using cloud or [GridFS][3]?
Here's how I set the user avatar:
```
const setUserAvatar = async (req, res) => {
try {
if (!req.user || !req.user.id) {
return res.status(401).json({ message: 'Unauthorized' });
}
const user = await User.findById(req.user.id);
if (!user) {
return res.status(404).json({ message: 'User not found' });
}
if (!req.file) {
return res.status(400).json({ message: 'No file uploaded' });
}
const fileName = `avatar_${user.id}_${Date.now()}.png`;
const filePath = path.join(__dirname, '..', 'uploads', fileName);
fs.writeFileSync(filePath, req.file.buffer);
user.avatar = { data: fileName };
await user.save();
res.status(200).json({ message: 'Avatar uploaded successfully' });
} catch (error) {
console.error('Error uploading avatar', error);
res.status(500).json({ message: 'Internal Server Error' });
}
};
```
And get:
```
const getUserAvatar = async (req, res) => {
const userId = req.user.id;
try {
const user = await User.findById(userId);
if (user.avatar.data === null) {
return res.status(404).json({ message: 'No avatar found' })
}
if (!user || !user.avatar.data) {
res.send(user.avatar.data)
} else {
const filePath = path.join(__dirname, '..', 'uploads', user.avatar.data);
const avatarData = fs.readFileSync(filePath);
res.setHeader('Content-Type', 'image/*');
res.send(avatarData);
}
} catch (error) {
console.error('Error fetching avatar', error);
res.status(500).json({ message: 'Internal Server Error' });
}
};
```
How I handle an avatar change on the front end:
```
const handleAvatarChange = async (e) => {
const token = localStorage.getItem('token');
if (token) {
try {
const formData = new FormData();
formData.append('avatar', e.target.files[0])
const response = await fetch('RENDERLINK/avatar', {
'method': 'POST',
'headers': {
'Authorization': `Bearer ${token}`,
},
'body': formData,
'credentials': 'include'
})
if (response.status === 200) {
getUser()
toast.success('Avatar changed successfully')
} else if (response.status === 400) {
toast.error('No file selected')
} else {
toast.error('Error changing avatar')
}
} catch (error) {
toast.error('Oops! Something went wrong. Please try again later.')
}
} else {
console.log('No token found')
navigate('/login')
}
}
```
Fetching user data including the avatar:
```
const getUser = async () => {
const token = localStorage.getItem('token');
if (token) {
try {
const response = await fetch('RENDERLINK/profile', {
'method': 'POST',
'headers': {
'Content-Type': 'application/json',
'Authorization': `Bearer ${token}`,
},
'credentials': 'include'
})
if (response.ok) {
const data = await response.json();
setUser({ username: data.username, email: data.email, avatar: data.avatar.data })
if (data.avatar.data !== null) {
// Fetch and set the avatar image
const avatarResponse = await fetch('RENDERLINK/get_avatar', {
headers: {
'Authorization': `Bearer ${token}`,
},
credentials: 'include',
});
const avatarBlob = await avatarResponse.blob();
const avatarUrl = URL.createObjectURL(avatarBlob);
setUser((prevUser) => ({ ...prevUser, avatar: avatarUrl }));
setLoading(false)
}
} else if (response.status === 500) {
toast.error('Oops! Something went wrong. Please try again later.')
}
} catch (error) {
toast.error('Oops! Something went wrong. Please try again later.')
}
} else {
console.log('No token found')
navigate('/login')
}
}

spring-cloud-stream-binder-kafka-streams consumer shuts down when RuntimeException occurs |
I am migrating my deprecated spring security code and I am facing a problem : after the user's authentication (and he is authenticated), the spring contextHolder seems to be lost and the authentication vanishes. Therefore my connection does not work and the first api call redirects again to the login page
I followed this documentation to migrate from WebSecurityConfigurerAdapter to the new spring security way : https://spring.io/blog/2022/02/21/spring-security-without-the-websecurityconfigureradapter
I removed all complex code to start fresh from base username/password authentication. This is the whole SecurityConfiguration file I have. I still have the same problem :

# Goal
I want to have two search bars, and each of them can:
- Display suggestions as typing
- Use arrow keys to select item
- Each item can be customized
Because of the last bullet I don't want to use [`<datalist>`](https://developer.mozilla.org/en-US/docs/Web/HTML/Element/datalist "<datalist>: The HTML Data List element - HTML: HyperText Markup Language | MDN") tag as it's limited in style. I also use Deno Fresh, which is based on Preact, which is based on React. At the time I wasn't aware of guides on navigate through list by arrow keys [in React](https://stackoverflow.com/q/42036865/3416774), only [in vanilla JS](https://deepak-pundir.hashnode.dev/how-to-navigate-a-list-with-arrow-keys-in-vanilla-js "How to navigate a list with arrow keys in vanilla js ?"), and I think using the vanilla version will be simpler, so currently I'm using it.
If you are interested in how to achieve the goal in general and not the question in title, check out [my final solution](https://stackoverflow.com/a/78231149/3416774).
# Problem
When a list is navigated by keyboard, the other is also triggered. My idea is to have the script targets different lists, and when users unfocus an input field it will be deactivated. I try having this on the script:
```ts
if (list === 'deactivate') return
```
And on each handler I have:
```ts
onBlur={(e) => script('deactivate')}
```
But it still doesn't work. Do you have any suggestion?
# Code
**`search.jsx`**:
```js
export default function SearchBar() {
const [keyword1, setKeyword1] = useState("");
const [keyword2, setKeyword2] = useState("");
const list1 = [ 'rabbits', 'raccoons', 'reindeer', 'red pandas', 'rhinoceroses', 'river otters', 'rattlesnakes', 'roosters' ]
const list2 = [ 'jacaranda', 'jacarta', 'jack-o-lantern orange', 'jackpot', 'jade', 'jade green', 'jade rosin', 'jaffa' ]
return (
<div className="search-bar-container">
<input
type="text"
placeholder={'Search list 1'}
value={keyword1}
onInput={(e) => {
setKeyword1(e.target.value);
script('1');
}}
onBlur={(e) => script('deactivate')}
/>
<br />
<ul id={'Suggested list 1'}>
{keyword1 !== '' ? list1.filter(keyword => keyword.includes(keyword1)).map(
(item) => <li>{item}</li>,
) : ''}
</ul>
<div>
Your selected item is :<span id="Item 1"></span>
</div>
<input
type="text"
placeholder={'Search list 2'}
value={keyword2}
onInput={(e) => {
setKeyword2(e.target.value);
script('2');
}}
onBlur={(e) => script('deactivate') }
/>
<br />
<ul id={'Suggested list 2'}>
{keyword2 !== '' ? list2.filter(keyword => keyword.includes(keyword2)).map(
(item) => <li>{item}</li>,
): ''}
</ul>
<div>
Your selected item is :<span id="Item 2"></span>
</div>
</div>
);
}
```
**`script.ts`**:
```ts
export function script(list: "1" | "2" | 'deactivate') {
if (list === 'deactivate') return
if (window !== undefined) {
const ul = document.getElementById(`Suggested list ${list}`);
const result = document.getElementById(`Item ${list}`);
//the rest of the script
```

just for me, I'm experimenting with GLFW (compiling with **g++ -o nxtBluePixel nxtBluePixel.cpp -lglfw -lGLEW -lGL** ) to simply draw a blue box and moving it up/down/left/right. I want to output a message "out of bounds" when the box touches the edges of the visible area, which should logically be -1 or 1 (in those so-called normalized OpenGL coords, so i read). But the box keeps continuing to move in a "invisible" region outside (and is invisible) but no message is displayed until a while (at least 10 hits or so on a key outside the edge boundary ... ChatGPT 4 can't help me, it says:
*"Correct Boundary Check: If you want the "out of bounds" message to appear as soon as the point is about to leave the visible area, your original check without the large epsilon is logically correct. However, if the message appears too late or too early, it might be due to how the point's position is updated or rendered, not the boundary check itself."*
any ideas ? I never use OpenGL so I wanted to try... but this is typically the kind of very annoying problems i hate!
and here my code:
#include <GL/glew.h>
#include <GLFW/glfw3.h>
#include <iostream>
#include <string>
#include <cctype>
GLint worldWidth = 400;
GLint worldHeight = 300;
// Starting position of the pixel
float currX = 0.0f;
float currY = 0.0f;
float stepSize = 1.0f / worldWidth;
float speed = 2.0f;
void updateWorld(char keyPressed, float speed){
switch (keyPressed) {
case 'W':
//up
currY += stepSize*speed;
break;
case 'A':
//left
currX -= stepSize*speed;
break;
case 'S':
//down
currY -= stepSize*speed;
break;
case 'D':
//right
currX += stepSize*speed;
break;
}
//using openGL 'normalized' coords i.e. between -1 and 1
if (currX >= 1.0 || currX <= -1.0 || currY >= 1.0 || currY <= -1.0){
printf("OUT OF BOUNDS !!!!");
}
}
void key_callback(GLFWwindow* window, int key, int scancode, int action, int mods) {
char key_str = '0';
if (action == GLFW_PRESS || action == GLFW_REPEAT) {
switch (key) {
case GLFW_KEY_W:
key_str = 'W';
break;
case GLFW_KEY_A:
key_str = 'A';
break;
case GLFW_KEY_S:
key_str = 'S';
break;
case GLFW_KEY_D:
key_str = 'D';
break;
case GLFW_KEY_Q:
printf("Bye ...");
glfwSetWindowShouldClose(window, GL_TRUE);
break;
default:
printf("unknown key pressed \n");
break;
}
updateWorld(key_str, speed);
}
}
int main(void) {
GLFWwindow* window;
// Initialize the library
if (!glfwInit())
return -1;
//remove win frame
//glfwWindowHint(GLFW_DECORATED, GLFW_FALSE);
// Create a windowed mode window and its OpenGL context
window = glfwCreateWindow(worldWidth, worldHeight, "Move Pixel with Keyboard", NULL, NULL);
if (!window) {
glfwTerminate();
return -1;
}
// Make the window's context current
glfwMakeContextCurrent(window);
// Set the keyboard input callback
glfwSetKeyCallback(window, key_callback);
// Initialize GLEW
glewExperimental = GL_TRUE;
if (glewInit() != GLEW_OK) {
std::cerr << "Failed to initialize GLEW" << std::endl;
return -1;
}
//glfwGetFramebufferSize(window, &worldWidth, &worldHeight);
// Define the viewport dimensions
glViewport(0, 0, worldWidth, worldHeight);
// Set point size
glPointSize(10.0f); // Increase if you want the "pixel" to be bigger
// Loop until the user closes the window
while (!glfwWindowShouldClose(window)) {
// Render here
glClear(GL_COLOR_BUFFER_BIT);
// Set the drawing color to blue
glColor3f(0.0f, 0.0f, 1.0f); // RGB: Blue
// Draw a point at the current position
glBegin(GL_POINTS);
glVertex2f(currX, currY); // Use the updated position
glEnd();
// Swap front and back buffers
glfwSwapBuffers(window);
// Poll for and process events
glfwPollEvents();
}
glfwTerminate();
return 0;

Aren't you meant to be passing a **blob-URL** for the image instead of just blob-data?
Because it doesn't look like you're converting the blob to a URL with this...
canvas.toBlob(function (blob){
jQuery.ajax({
url:"//domain.com/wp-admin/admin-ajax.php",
type: "POST",
data: {action: "addblobtodb", image: blob},
success: function(id) {console.log("Succesfully inserted into DB: " + id);
}
});
So I would try this...
canvas.toBlob((blob)=>{
let Url=URL.createObjectURL(blob);
jQuery.ajax({
url:"//domain.com/wp-admin/admin-ajax.php",
type: "POST",
data: {action: "addblobtodb", image: Url}, // <-- Image blob url passed here
success: function(id) {console.log("Succesfully inserted into DB: " + id);}
});
},'image/png',1); // <--- specify the type & quality of image here

My device is Xiaomi 11 Lite 5G NE (lisa) and I am using the defconfig from ./arch/arm64/configs/vendor/lahaina-qgki_defconfig.
I am using clang as CC and CLANG_TRIPLE as aarch64-linux-gnu- (both from proton-clang) while
using aarch64-linux-android- as CROSS_COMPILE (from here https://github.com/ibnudz/aarch64-linux-android-4.9)
I am trying to build a kernel of that device but I faced some errors (https://github.com/renoir-development/android_kernel_xiaomi_sm8350/tree/lineage-19.1)
During the compilation, I got undefined error for these functions `get_hw_country_version, get_hw_version_platform, get_hw_version_build, get_hw_version_major, get_hw_version_minor` in ./drivers/soc/qcom/icnss2/qmi.o
By doing `grep -r "get_hw_country_version"`, I was able to locate the function was declared in ./drivers/misc/hwid.c while the header file is located in ./include/linux/hwid.h
I found that qmi.c (mentioned above) already has hwid.h included and some defined values in hwid.h successfully be used by qmi.c, but I am still getting the undefined reference error for those functions. How do I fix this issue? |
