There are 8 Linux namespaces which isolates PIDs, Network, Users, etc.
https://man7.org/linux/man-pages/man7/namespaces.7.html
It allows a namespaced process to have independent PIDs, network devices, users, etc.
They are kernel resources but only visible within one specific namespace.
They are guaranteed to not affect other processes.
However BPF code is not. Once injected in one namespace it has access to everything.
Is there a need for BPF namespace? |

It's likely that Firefox is not looking for your `userChrome.css` on startup.
1. Open up a tab and navigate to `about:config` and click `Accept the Risk and Continue`.
2. In the `Search for Preference` box type `userprof`.
3. It should find the `toolkit.legacyUserProfileCustomizations.stylesheets` option. Just click the `toggle` button on the far right to change the setting to `true`.
4. Modify your `userChrome.css` to this:
````css
.tab-background[selected] {
background-color: #dd9933 !important;
background-image: none !important;
}
````
5. Restart your browser.
**Note**: looking with the Browser Toolbox it would appear that Firefox adds a `selected=""` attribute to the currently selected tab which is why your css selector of `.tab-background[selected="true"]` no loger works. |

I would like to leverage [Vue3 Suspense](https://vuejs.org/guide/built-ins/suspense.html#combining-with-other-components) to initiate a loading state at the parent level that triggers animations in the children. When the request resolves at the parent level, I would like to remove the animation from the children.
App Header:
```pug
router-view(v-slot="{ Component, route }")
template(v-if="Component")
transition(:name="route.meta.transition" appear)
KeepAlive
Suspense
component(:is="Component")
template(#fallback='')
div.loading-div LOADING !!
```
Parent Template:
```javascript
<template lang="pug">
section.discover-row
div.discover-row-carousel
DiscoverItem(
v-for="(item, index) in DiscoverItemStore.automobiles"
:key="item._id"
:item="item"
:index="index"
)
</template>
<script setup>
...
import { useDiscoverItemStore } from "@/stores/DiscoverItemStore"
const DiscoverItemStore = useDiscoverItemStore()
DiscoverItemStore.fetchItems()
</script>
```
Child Template:
```pug
Suspense
template(#default='')
div.item SHOW SOME STUFF
template(#fallback='')
div.loading-div CHILD LOADING !!
```
—
Request (from pinia store):
```javascript
async fetchItems() {
this.automobiles = []
this.items = []
this.loading = true
try {
this.items = await fetch(discoverUrl)
.then((response) => response.json())
this.automobiles = [...this.items.Cars, ...this.items.Suvs, ...this.items.Trucks, ...this.items.Vans]
this.loading = false
...
```
————————————————————
How can I trigger the loading state at the parent level then show `CHILD LOADING !!` on each child instance until the request to `fetchItems()` at the parent level is resolved?

I expect this not to throw an exception on the new SwingNode(); line, but to create a new SwingNode.
I saw this Q/A about the same problem, but I have javafx-swing included in my pom file.
([https://stackoverflow.com/questions/55874607/the-class-swingnode-in-openjfx-causes-problems](https://stackoverflow.com))
This is the javafx section from pom.xml and it looks like all the relevant libraries are there.

I do not understand this. I believe it is my `dbContext` that handles the "saving the entity changes". How can I have a SQL syntax error? I cannot find "Returning 1" anywhere in my code.
I have tried deleting the row manually in my database. That works.
All other operations (GET, POST and PUT) work just fine.
I have tried running this with holding points to see where the error occurs but everything seems to execute without issue.
I am grateful for any hints. I am obviously very new to this ;)
Edit: MariaDB version 11.2.2
Edit2: This is my Alert class:
public partial class Alert
{
public int AlertId { get; set; }
public DateTime? Zeitpunkt { get; set; }
public string? Quelle { get; set; }
public string? AlertStatus { get; set; }
public string? AlertTyp { get; set; }
public string? BetroffeneSysteme { get; set; }
public virtual ICollection<Vorfall> Vorfalls { get; set; } = new List<Vorfall>();
}
and this is its entity configuration:
modelBuilder.Entity<Alert>(entity =>
{
entity.HasKey(e => e.AlertId).HasName("PRIMARY");
entity
.ToTable("alert")
.HasCharSet("utf8mb4")
.UseCollation("utf8mb4");
entity.Property(e => e.AlertId)
.HasColumnType("int(11)")
.HasColumnName("AlertID");
entity.Property(e => e.AlertStatus).HasMaxLength(255);
entity.Property(e => e.AlertTyp).HasMaxLength(255);
entity.Property(e => e.BetroffeneSysteme).HasMaxLength(255);
entity.Property(e => e.Quelle).HasMaxLength(255);
entity.Property(e => e.Zeitpunkt).HasColumnType("datetime");
});
edit3: I found the parameterized query. It goes thus:

accessibilitytools, wang's avi library and kprogresshud are very old libraries, originally hosted in jcenter but now not available anymore.
Working with old libraries is always difficult. My suggestion is to download the source code from github and try to integrate them into your project (if the license allows it). This comes, of course, with some risks or adjustments in the code.
For the Microsoft library, you can integrate the new one here: https://github.com/Azure/azure-notificationhubs-android

I have a relatively large PostgreSQL (v12) table storing JSONB data that has unintentional duplicate data (based on a composite unique index on two columns, `aCol` and `bCol`). In order to create that index, I have to first delete all of the accidental duplicates from the DB. This works fine in 2/3 of our DB servers (servers for different environments, i.e. Dev and Prod, all with the same DB schema), but in the 3rd the query will just never finish, and I've let it run for up to 2 hours (in the other environments it takes a matter of minutes).
I've tried configuring the resources and configuration settings to be the same in all environments; for example, the RAM, disk size and ops, CPU, `effective_io_concurrency`, etc. I've also compared the sizes of the tables and I don't think that's the issue, because one of the servers that does complete has ~2 million records for a total of ~9 GB while the one that fails has ~400,000 records for a total of ~2 GB.
The query in question is:
```sql
DELETE FROM aTable a USING aTable b
WHERE a.aCol = b.aCol
AND a.bCol = b.bCol
AND a.id != b.id
AND a.created_at <= b.created_at
```
I'm not a DBA or SQL expert by any means so I would definitely appreciate any insight into what else might be causing this query to hang in 1 specific environment, or whether there is a more efficient way to achieve what I'm trying to do that could potentially bypass the issue. Thanks in advance
**Edit:** In response to the comments, here are the explain plans for the queries in the two environments.
Working environment:
```
Delete on aTable a (cost=800504.63..5706702.06 rows=72439076 width=12)
-> Merge Join (cost=800504.63..5706702.06 rows=72439076 width=12)
Merge Cond: ((a.aCol = b.aCol) AND (a.bCol = b.bCol))
Join Filter: ((a.id <> b.id) AND (a.created_at <= b.created_at))
-> Sort (cost=400252.31..404391.52 rows=1655683 width=50)
Sort Key: a.aCol, a.bCol
-> Seq Scan on aTable a (cost=0.00..184763.83 rows=1655683 width=50)
-> Materialize (cost=400252.31..408530.73 rows=1655683 width=50)
-> Sort (cost=400252.31..404391.52 rows=1655683 width=50)
Sort Key: b.aCol, b.bCol
-> Seq Scan on aTable b (cost=0.00..184763.83 rows=1655683 width=50)
```
Failing environment:
```
Delete on aTable a (cost=0.00..1794266.00 rows=59613596 width=12)
-> Nested Loop (cost=0.00..1794266.00 rows=59613596 width=12)
-> Seq Scan on aTable a (cost=0.00..40365.00 rows=395600 width=50)
-> Index Scan using idx_aTable_aCol on aTable b (cost=0.00..4.42 rows=1 width=50)
Index Cond: (aCol = a.aCol)
Filter: ((a.id <> id) AND (a.created_at <= created_at) AND (a.bCol = bCol))
```
I notice that the failing table seems to be trying to use a hash index on `aCol`, though the tables in both environments have that exact same index. Not really sure what to make of that, because if anything, I figured that would've sped things up |

My favorite list of [tips (explained in detail here)][1] is as follows
> 1. Try to restrict the queries result set by using the WHERE clause.
> 2. Try to restrict the queries result set by returning only the particular columns from the table, not all the table's columns.
> 3. Use views and stored procedures instead of heavy-duty queries. (This item usually does not apply to MySQL.)
> 4. Whenever possible, try to avoid using SQL Server or MySQL cursors. (SQL is shines when doing things in bulk.)
> 5. If you need to return the total table's row count, you can use an alternative way instead of the SELECT COUNT(*) statement.
> 6. Try to use constraints instead of triggers, whenever possible.
> 7. Use table variables (if available) instead of temporary tables.
> 8. Try to avoid the HAVING clause, whenever possible.
> 9. Whenever possible, try to avoid using the DISTINCT clause.
> 10. Include SET NOCOUNT ON statement into your stored procedures to stop the message indicating the number of rows affected by a T-SQL
> statement.
> 11. Use select statements with the TOP keyword or the SET ROWCOUNT statement if you need to return only the first n rows. (This is may
> not help much if there is an unavoidable `ORDER BY`.)
> 12. Use the FAST number_rows table hint if you need to quickly return 'number_rows' rows.
> 13. Try to use UNION ALL statement instead of UNION, whenever possible.
> 14. Do not use optimizer hints in your queries.

I found this interesting bot from James Bachini https://github.com/jamesbachini/Market-Maker-Bot. I tried on ETH Mainet and works fine then I tried on Sepolia Testenet and I got stuck in a CALL_EXCEPTION'

I am simulating CPU scheduling algorithms for a class. I have a struct called job that contains the basic info for each job, and I'm trying to order a priority queue of these jobs in order from smallest number of cycles needed to largest number of cycles needed. This is currently my custom comparator to do that:
```
class CompareJobTime {
public:
bool operator()(job job1, job job2) {
if (job1.cycles < job2.cycles) {
return false;
}
else
return true;
}
};
```
and this is how I'm using it in the priority queue declaration:
` priority_queue<job, vector<job>, CompareJobTime> jobTPQ;`
This is the error it keeps throwing:
"Microsoft Visual Studio\2022\Community\VC\Tools\MSVC\14.34.31933\include\xutility
Line:1096
Expression: invalid comparator"
Any help would be greatly appreciated, as I really don't have a clue where to go from here when it comes to debugging. Thanks!
I've tried changing up the definition in a couple ways, but I'm not sure what's wrong with it. I have also tried using decltype instead of a comparator class, but I couldn't get that to work since I was writing the comparator function as a member of the class this is all being written in. |

It would have been ideal to use hasManyThrough but this would mean some modifications to your schema.
However, you can achieve this result by chaining Eloquent relationships and a custom query.
For your example, you can do this by
getting all the role IDs of the user then getting all tasks associated with these roles and finally fiter schedules based on this ID'.
Or you can define a custom method on user to do same.
example with code.
```
// In your Schedule model
public static function getSchedulesForUser($user)
{
// Get the role IDs of the user
$roleIds = $user->roles()->pluck('id');
// Get tasks associated with these roles using Eloquent relationship
$tasks = Task::whereHas('roles', function ($query) use ($roleIds) {
$query->whereIn('id', $roleIds);
})->get();
// Extract task IDs from the tasks collection
$taskIds = $tasks->pluck('id');
// Return the schedules associated with these tasks
return self::whereIn('task_id', $taskIds)->get();
}
````
or
```
//in your User model
public function schedules()
{
// Get role IDs
$roleIds = $this->roles()->pluck('roles.id');
// Get task IDs associated with these roles
$taskIds = Task::whereHas('roles', function ($query) use ($roleIds) {
$query->whereIn('roles.id', $roleIds);
})->pluck('tasks.id');
// Return schedules associated with these tasks
return Schedule::whereIn('task_id', $taskIds)->get();
}
```
or
```
//directly in your controller
// Get the logged-in user
$user = Illuminate\Support\Facades\Auth::user();
// Get the role IDs of the logged-in user
$roleIds = $user->roles->pluck('id');
// Get the task IDs associated with these roles
$taskIds = DB::table('task_role')
->whereIn('role_id', $roleIds)
->pluck('task_id');
// Get the schedules associated with these tasks
$schedules = Schedule::whereIn('task_id', $taskIds)->get();

How to reduce noise in recordings with a known audio file |
Your code has compile errors when I try to run with the version of `iverilog` that I have installed (10.3).
However, the code produces the expected output when I run with the Cadence and Synopsys simulators:
result_matrix[0] = 0.000000
result_matrix[1] = 0.000000
result_matrix[2] = 0.000000
result_matrix[3] = 0.000000
result_matrix[0] = 7.000000
result_matrix[1] = 10.000000
result_matrix[2] = 15.000000
result_matrix[3] = 22.000000
result_matrix[0] = 7.000000
result_matrix[1] = 10.000000
result_matrix[2] = 15.000000
result_matrix[3] = 22.000000
I think it is a bug in the version of `iverilog` you are using. Try your code on [EDA Playground][1].

It would be helpful to show the `$time` and hierarchy `%m` in your `$dsiplay` statements.

I'm asking how are labels managed by C.
EX:
if (false)
label: printf("HELLO ");
printf("WORLD ");
goto label;
Prints WORLD HELLO on GCC
is it undefined behavior? (the label definition isn't handled as an instruction by the compiler) |
`foo()` is taking in a primitive `int` *by value*, so it is a *copy* of whatever value you pass in. There is no reference.
It doesn't matter what `foo()` does to `y`, that value is not reflected back to the caller.
Also, there is no such thing as "point at a value", either. You can point at a variable, but not at a value.
> then `x` becomes 3 because `y=y+2` and `y` was pointing at the value 1 of `x`.
>
> `foo(a[x])` is called with `a[3]` (which doesnt exists). `x` is decremented to 2.
This is incorrect. It is `y`, not `x`, that becomes 3. `x` is still 0 at this point. So the subsequent call to `foo(a[x])` is using `a[0]` instead, which then decrements `x` to -1 and then sets `x` to 5. |
You have not set the `provider` and `registration` properties correctly for Keycloak:
- only `user-name-attribute` is present for `provider` conf, which is not enough
- `issuer-uri` is a `provider` property, not a `registration` one (your IDE should lint that)
- `issuer-uri` is probably `http://localhost:8080/realms/sdia3` (and not `http://localhost:8080/realms/sdia3/account`)
- when you're not using one of the "magic" ones (like `google`is), you should explicitly reference the `provider` to use in the `registration`
As Keycloak is OIDC compliant, setting `spring.security.oauth2.client.provider.keycloak.issuer-uri=` with the **exact value of the `iss` claim in one of your tokens** should be enough (even trailing slash, if any, and case are important). Spring will pull the rest of the conf from the `.well-known/openid-configuration`.
Here is the configuration you're probably looking for (in the YAML format):
```yaml
keycloak-issuer: http://localhost:8080/realms/sdia3
keycloak-client-secret: you-should-not-commit-this-in-git-or-post-it-on-stackoverflow
spring:
security:
oauth2:
client:
provider:
keycloak-provider:
issuer-uri: ${keycloak-issuer}
user-name-attribute: preferred_username
registration:

authorization-grant-type: authorization_code
client-id: lient-cree-customer
client-secret: ${keycloak-client-secret}
scope: openid, profile, email, offline_access
client-name: keycloak
```
As you seem to be at the very beginning of your Spring with OAuth2 journey, you might find [this tutorials I wrote](https://github.com/ch4mpy/spring-addons/tree/master/samples/tutorials#securing-spring-applications-with-oauth2) useful. |

Right now i am reseting the watchdog timer (i think) in the while loop where it checks if the connection was successful. If i dont do that reset it crashes in the while loop already. But since i have the WD reset, it crashes in the else{} part where I print "debug 4". It prints the "debug 4" on the serial monitor and after 5 seconds it crashes.
It should write Connection Failed and then i want it to go back to the Form where i can enter the data. The same for Missing Data.
I know my solution with reseting the timer all the time is no solution either so if you have and other solutions i am happy to hear them.
So i would be glad if anyone could help me resolving this issue!
Thanks!
I entered the wrong Wifi Data and it reset the ESP32 because it triggered the Watchdog. I expected it to Print Connection failed but it reseted. |

How to solve compiler error: no matching function for call to 'dmhFS::dmhFS()' in my case? |
it seems to me you could achieve your goal by means of formulas
if you insert one column and one row you could use this formula
=IF(SUM(G$5:G5)<G$2;IF(SUM(F6:$F6)<8;1;"");"")
[![enter image description here][1]][1]
or you can keep your original rows and columns layout and adopt this other formula:
=IF(ROW()=5;
IF(COLUMN()=7;
1;
IF(SUM(F5:$G5)<8;1;""));
IF(SUM(G4:G$5)<G$2;
IF(COLUMN()=7;
1;
IF(SUM(F5:$G5)<8;1;""));
"")
)
[![enter image description here][2]][2]
Finally here's the corresponding amendment of your code (forgive the polish):
Sub AutoFill()
Dim ws As Worksheet
Dim col As Integer
Dim row As Integer
Dim suma As Integer
Dim liczba_osob As Integer
' Ustaw arkusz, na którym chcesz dzialac
Set ws = ThisWorkbook.Sheets("01")
' Wyczysc zakres G5:AD36
ws.Range("G5:AD36").ClearContents
' Iteruj przez kolumny od G do Y
For col = 7 To 30
' Pobierz liczbe osób w pracy w danej godzinie
liczba_osob = ws.Cells(2, col).Value
' Ustaw sume kolumny na 0
suma = 0
' Uzupelnij komórki wartoscia 1 do momentu, gdy suma wiersza bedzie równa liczbie osób w pracy
For row = 5 To 36
' Sprawdz, czy w biezacym wierszu nie przekracza liczby osób w pracy '<-----|

Looking to match a table of X,Y,Z points between two sets of data.
The difference between the two sets is that the sign of the Y value is flipped.
For example in this screenshot I set "target" as the values I'm looking for, where the Y value is the negative of the value in column D.
![sample data table + desired targets[1]][1]
I am using a combination of index and match, but this finds exact matches not the closest match:
=INDEX($C$7:$C$1048576; MATCH(1; (I120=$D$7:$D$1048576) * (J120=$E$7:$E$1048576) * (K120=$F$7:$F$1048576); 0))
In a data set of a few hundred points, about one hundred won't be exact matches.
I'd like a formula to find the closest match to the target points.

After establishing PACE PIN authentication, I am trying to implement secure messaging to be able to send secure APDU commands. I based my implementation on the ICAO 9303 part 11 manual, chapter 9.8, page 63 : https://www.icao.int/publications/Documents/9303_p11_cons_en.pdf,
and on this Java code that I used : https://github.com/ecsec/open-ecard/blob/master/ifd/ifd-protocols/pace/src/main/java/org/openecard/ifd/protocol/pace/SecureMessaging.java, as well as on a log from the PlatinumReader where secure messaging has already been implemented.

Here are the data from the PlatinumReader that I used where it works fine, and I'm trying to get the same result:

1c f1 a6 a0 b1 8d 0c 8f 8e 08 71 b6 0b b9 3b 7a
f1 08 00
Here is the test i do by using the same values :
string apduSM = chipherAPDU("00a4040c07a0000002471001", "3d7155f3791c313c2924f51ae60f1ac9" , "b5feb9488f17be03e54c7d80907e8a1f");
addLogMsg("ADPU SM : " + apduSM);
And here is my result :
ADPU SM : 01A948E4F1A82356C11CF1A6A0B18D0C8F
The Keys used are ephemeral so i can post them and it just a testing phase:
**Key: K_MAC - derived MAC key (K_MAC [PACE])
b5 fe b9 48 8f 17 be 03 e5 4c 7d 80 90 7e 8a 1f**

Matrix Multiplication Testbench Yields Inconsistent Results |
Your backtracking doesn't work, as you break when the count of a letter drops to 0, but the loop that restores the counts unconditionally adds all the letters back.
If you remove the `break`, then your code will work correctly without cloning.
```java
for (char ch : word.toCharArray()) {
int letterIndex = ch - 'a';
if (letterCount[letterIndex] == 0)
flag = false;
letterCount[letterIndex]--;
sword += score[letterIndex];
}

The existing code renders. However, when I remove `Router` from line 2 as an import, even though it's not being used, it breaks.
**Correction: The page still renders when I remove Router. However, it just displays a blank page. When I inspect it, I no longer get anything in the <div id="root"> tags.**
When I compile, of course I get "Line 2:27: 'Router' is defined but never used no-unused-vars"
Why is this? Or does anyone have any insight?
```jsx
import React from 'react';
import { BrowserRouter as Router, Routes, Route } from 'react-router-dom';
import HomePage from './HomePage';
import PlanTripPage from './PlanTripPage';
import NavBar from './NavBar';
import ItineraryPage from './ItineraryPage';
import './App.css';
function App() {
return (
<div>
<NavBar />
<Routes>
<Route exact path="/" element={<HomePage />} />
<Route path="/plan-trip" element={<PlanTripPage />} />
<Route path="/itinerary" element={<ItineraryPage />} />
</Routes>
</div>
);
}
export default App;
```
Here is my index file.
```jsx
import React from 'react';
import ReactDOM from 'react-dom';
import { BrowserRouter } from 'react-router-dom';
import App from './App';
import './index.css';
ReactDOM.render(
<BrowserRouter>
<App />
</BrowserRouter>,
document.getElementById('root')
);

For me the only way this worked out was to set UISegmentedControl's background image an empty image using UIImage().
Like so:
`segmentedControl.setBackgroundImage(UIImage(), for: .normal, barMetrics: .default)`
Also,
`segmentedControl.setDividerImage(UIImage(), forLeftSegmentState: .normal, rightSegmentState: .normal, barMetrics: .default)`
if you want to get rid of the divider as well. |
I am using TeamsFx SDK. I want to send a proactive message to a user. From reading documentation, it seems that recommended way is to listen to OnMembersAdded or OnMessageActivity and save the conversation reference to a persistent storage, so it can be later used for sending proactive messages.
But what if for whatever reason the conversation reference didn't get persisted? (let's say the network went down when a user was installing the app/bot into their Teams, so the conversation reference was never saved).
How would I recover from a situation when I need to send a proactive message but I don't have a reference to the conversation reference?
Is that possible to construct the conversation reference just by having the Aad ID of the user and the Bot/App Ids?
thank you

I believe that `Image` doesn't like null `src`. You should change your code to something like:
```
"use client"
import { useKindeBrowserClient } from '@kinde-oss/kinde-auth-nextjs'
import Image from 'next/image';
import React from 'react'
function DashboardHeader() {
const {user} = useKindeBrowserClient();
return (
<div>
{user?.picture && <Image src={user?.picture} alt='logo'
width={40}
height={40}
/>}
</div>
)
}
export default DashboardHeader
```
To drop the `Image` if you don't have the data or:
```
"use client"
import { useKindeBrowserClient } from '@kinde-oss/kinde-auth-nextjs'
import Image from 'next/image';
import React from 'react'
function DashboardHeader() {
const {user} = useKindeBrowserClient();
return (
<div>
<Image src={user?.picture ? user.picture : '/some/fallback.png'} alt='logo'
width={40}
height={40}
/>
</div>
)
}
export default DashboardHeader
```
to get a fallback image. |
I am trying to make a primitive minesweeper game, my program has two classes, one of which is Point, that is supposed to be made into an array of objects.
```
public Point(int x, int y, int status, int contents)
```
Those are the values that it takes, an object of a sort is created.
Then, i have to get an array of those objects in specified size^2 that is set by the user.
After that, i take the regular size and assign a Game Field instance, which supposedly creates a 2d array which then is further initialised..
Long story short, i want the 2d array take values of each object from my 1d array as each point.
Now, i'll try show what i want and what do i have on hands.
`public GameField(int size, int treasures, int bullets)`
these are the values field takes, they are being switched based on difficulty the user chooses.
```
public void Initialize(int size, int treasures, int bullets)
{
for (int i = 0; i < size; i++)
{
for (int j = 0; j < size; j++)
{
int[i, j] field = new Point(....); //How?
}
}
}
```
My problem appears here. The point has two other attributes that show its status on field and contents (treasure, enemy or blank) that are also being randomised. I had an idea of ditching the coordinates part and make the player call a point by its index in array of objects but that really defeats the meaning of "Point", unless. I need an advice on how to make it make sense. |

The only difference is that they have different expiration times.
- `sessionStorage` will only be accessible while and by the window that created it is open.
- `localStorage` lasts until you delete it or the user deletes it.
Let's say that you wanted to save a login username and password you would want to use `sessionStorage` over `localStorage` for security reasons (i.e. another person accessing their account at a later time).
But if you wanted to save a user's settings on their machine you would probably want `localStorage`.
In conclusion
- `localStorage` - use for long term use.
- `sessionStorage` - use when you need to store something that changes or something temporary

In WooCommerce, I would like the add to cart button to be disabled if a certain attribute value is selected. The attribute taxonomy is "pa_badge-print" and the term slug value is "yes"
I have used this code:
```
add_filter( 'woocommerce_variation_is_purchasable', 'conditional_variation_is_purchasable', 20, 2 );
function conditional_variation_is_purchasable( $purchasable, $product ) {
## ---- Your settings ---- ##
$taxonomy = 'pa_badge-print';
$term_slug = 'yes';
## ---- The active code ---- ##
// Check if the product has attributes
if ( $product->get_attributes() ) {
// Loop through all product attributes in the variation
foreach ( $product->get_variation_attributes() as $variation_attribute => $term_slug ){
// Get the attribute taxonomy
$attribute_taxonomy = str_replace('attribute_', '', $variation_attribute);
// Get the term object by slug
$term = get_term_by( 'slug', $term_slug, $attribute_taxonomy );
// Check if the term exists and its slug is "yes"
if ( $term && $term->slug === $term_slug ) {
$purchasable = false; // Disable purchasable
break; // Exit the loop
}
}
}
return $purchasable;
}
```
And currently it disables add to cart on all attribute values. So for example, if the attribute value was "no", the add to cart should still show.
This is a screen shot of the product with the values no selected. The add to cart button should show with no values selected;

I had a Django service which had an app called "User". This app has 2 tables in, which are being migrated to the database using Django migration system. In order to change the architecture from monolith to micro-service, I broke down User app and add the models and APIs in another Fastapi project. But I didn't separate the database and during this time, I was changing User tables in database using my previous Django project migration system. But now I want to break down tables in the database and move them to the new database. What is the best practices of doing this? And how can I change migrations from Django to alembic? |

I use JavaScript and node. I need to read the raw bytes from the file.
I create a `Uint8array` and fill it with data from a file using `fs.Read`.
Then I output the data to the console of the array as a whole, and individual elements.
Instead of the values of the elements, I get zeros.
But it is clear that the array has non-zero data.
```
var buf1 = new Uint8Array( 4 );
fs.open( filePath, 'r+', function ( err, fd ) {
if (err) { console.error( err ) };
fs.read( fd, buf1, 0, buf1.length, 4,
function (err, bytes) {
if (err) { console.log(err) };
fs.close( fd, function (err) {
if (err) { console.log(err) };
}) }) });
console.log( buf1 );
console.log( buf1[0] );
console.log( buf1[1] );
console.log( buf1[2] );
console.log( buf1[3] );
```
[In the console, I see this:](https://i.stack.imgur.com/Te1VP.jpg)
```
var buf2 = new Uint32Array( buf1.buffer );
console.log( buf2 );
console.log( buf2[0] );
```

You need to have nested structures that mirror your nested JSON:
struct City: Decodable {
let id: Int
let city: String
}
struct ResponseObject: Decodable {
let items: [City]
let offset: Int
let limit: Int
}
And then:
do {
let result = try JSONDecoder().decode(ResponseObject.self, from: data)
print(result)
let cities = result.items
print(cities)
} catch {
print(error)
}
---
Note, in your original example, you included a JSON key, `updated_at` which was the date represented in number of seconds since 1970 (standard UNIX representation). So, to decode that:
struct City: Decodable {
let id: Int
let city: String
}
struct ResponseObject: Decodable {
let items: [City]
let offset: Int
let limit: Int
let code: Int
let updatedAt: Date
}
And then:
let decoder = JSONDecoder()
decoder.dateDecodingStrategy = .secondsSince1970
decoder.keyDecodingStrategy = .convertFromSnakeCase
do {
let result = try decoder.decode(ResponseObject.self, from: data)
print(result)
let cities = result.items
print(cities)
} catch {
print(error)
}
- - -
Note, when you see a somewhat abstract key name, such as `items`, that means that this might be a response structure used for various endpoints. In that case, we might to make this a [generic][1]:
struct ItemsResponse<T: Decodable>: Decodable {
let items: [T]
let offset: Int
let limit: Int
let code: Int
let updatedAt: Date
}
And then:
let decoder = JSONDecoder()
decoder.dateDecodingStrategy = .secondsSince1970
decoder.keyDecodingStrategy = .convertFromSnakeCase
do {
let result = try decoder.decode(ItemsResponse<City>.self, from: data)
print(result)
let cities = result.items
print(cities)
} catch {
print(error)

Trying to generate LIN Slave wakeup frame from CAPL script in which I need to simulate below condition
1. System is in sleep.
2. My Node Connected to ECU will wakeup with three 250us pulse (LIN slave wakeup frame on Bus not 999us neither wakeup frame through 0x3C).
3. Send Diagnostic frame to my ECU with Checksum Error
4. send Unconditional frame to my ECU to get response from my ECU whether previous frame checksum Error is detected or not .
5.Again send diagnostic frame to my ECU with checksum Error
6. Again send Unconditional frame to get ECU response for checksum Error Detection.
7. put system in Sleep again.
Repeat 1 to 7 step to check same thing multiple times .
I need to support that anybody know how we can do this as i am able to generate checksum error but not able to generate LIN slave wakeup frame on bus through CAPL script.
its a sequence for one test case that I need to generate to check my LIN driver , as we got some issues from Client side and my LIN driver is failing in their test cases but client cant give their environment for testing (Automotive vehicle manufacturer confidential tools and environment).
Thanks
I tried t generate 250 us pulse through CAPL inbuild LIN function but after checking on Logic level of bus I cant see any pulses |

I am trying to wrap all the values of an arbitrary object with `Wrapper<T>`.
The function `makeKeyValueWrapperObjectFromJson`, first parses a JSON string, then given that parsed TypeScript object, it looks through all its values, construct a new `Wrapper<T>` and setting it as the value corresponding to the key of the object as typed by `MyDeterminedTypedObject`.
`key2` is supposed to be of type `number` but the JSON string has it as `"123"` which is parsed as string.
Is there anyway to write `makeKeyValueWrapperObjectFromJson`, such that it is able to create arbitrary instances of any tips just by 'inspecting' the type argument `MyDeterminedTypedObject` passed into the type parameter of the function?
