How to expand path to UNC including all server domain information?

I need to compare path strings, and can't work with any difference in the given information of an UNC path.


How to convert a path into the full UNC version, including server domain information, in Delphi?
thispath : String;

thispath := 'x:\testfolder_on_server';

thispath := ExpandUNCFIlename( thispath ) ; // '\\myserver\testfolder_on_server\'



But what I need is the UNC Path including all the domain information for my server path.
'\\myserver.local.commay\testfolder_on_server\'

Temporary block when using Credential Manager to Sign in with Google

I'm testing the 'Sign in with Google' flow with Credential Manager by following the indications in the official docs. So far, the process works as intended: it shows a bottom sheet with the available accounts and it allows me to sign in to the selected account.


However, I observed that if I dismiss the bottom sheet 4 times in a row, the bottom sheet doesn't appear anymore and I get the following exception:
androidx.credentials.exceptions.NoCredentialException: During begin sign in, failure response from one tap: 16: [28436] Caller has been temporarily blocked due to too many canceled sign-in prompts.



That exception seems to come from the old 'One Tap' flow. As explained in the One Tap docs, "If a user cancels several prompts in a row, the One Tap client will not prompt the user for the next 24 hours".


Which leads to my question:


If a user who is trying to sign in into my app dismisses the credential prompt 4 times in a row (which I can easily see happening), what should I do? Telling them that they cannot use the app for 24 hours seems a bit excessive. Is there any alternative?


NOTE:


It's important to point out that the old GoogleSignInClient didn't have this limitation.

Laravel Breeze with PrimeVue v4

This is an follow up to my previous post about a "starter kit" I created with Laravel and PrimeVue components.

The project has been updated with the following new changes:

* Upgraded to Laravel 11
* Updated to use Laravel Breeze backend instead of Fortify (for the potential to abstract this project as a fork of laravel/breeze with custom stubs)
* Upgraded PrimeVue to v4 (overhauled theming and light/dark mode)
* Removed PrimeFlex and re-added Tailwind CSS for utility styling




Feedback is welcomed as a GitHub issue or PR, thanks!

Is a back_insert_iterator valid for the lifetime of the container?

I think I know the answer to this, but I'd appreciate a sanity check.


Does iterator invalidation apply to std::back_insert_iterators?
#include
#include
#include

int main() {
auto v = std::vector{ 0, 1, 2 };
auto iter = std::back_inserter(v);
*iter++ = 3;
v.clear(); // invalidates iterators, but
*iter++ = 4; // back_insert_iterator is special?
assert(v.size() == 1 && v[0] == 4);
return 0;
}



This code works for me because the std::back_insert_iterator implementation from my vendor doesn't hold an iterator (or pointer or reference). It simply calls the container's push_back method.


But does the standard require that implementation? Could another vendor's back_insert_iterator hold and maintain a one-past-the-end iterator to use with a call to the container's insert method? It seems that would meet the requirements. This difference, of course, is that it would be vulnerable to invalidation.

---



I know cppreference.com is not authoritative, but it's more accessible than the standard.



[A vector's clear method] [i]nvalidates any ... iterators referring to contained elements. Any past-the-end iterators are also invalidated. [cppreference.com, emphasis added]



A std::back_insert_iterator could be the poster child of a past-the-end iterator.

sorting algorithm in O(n) according a specific condition

Given an array A with n−1 numbers where n = 2k
for some integer k. One of the values appears exactly n/2
another appears exactly n/4, and so on. More formally, for all 1 ≤ k ≤ log n exists a value that appears exactly n/2^k times in the array. Describe an algorithm that sorts A with a run time complexity of Θ(n), and analyze its running time.
example: input: 5,1,2,1,2,2,2
output: 1,1,2,2,2,2,5


some important pointers:
1.the time comlexity should be Worst case
2.using a dictionary is not allowed
3.the solution should use a stack or other basic data structures


i tried using counting sort but it didnt work because the array doesnt contain values starting from 0 and up.
i also thought about using a hash map but the wanred time complexity would be expected and not worst case.
thanks for the help in advance

What rector rules do you use?

I have been playing around with Rector to ensure a more consistent codebase and there are a lot of rules to choose from. Additionally there's even a Laravel Rector package with more rules to choose from on top of that.

I am using a few, such as the early return rules and moving the property to the constructor as I think they're niceties but I'm interested in what rules the wider community uses.

All the rules seem like such good ideas but I'm not sure if it is wise to use them all, even if the application is pretty well tested. submitted by /u/TertiaryOrbit

is there a way to print a bank check from a template where the user only puts the amount and the name?

I've been trying on excel to create a template for printing a bank check i've set the dimensions and everything but always has the print issues as it's not perfectly aligned so i've thought in some other way like coding an entire program in python (gui) that only needs the information (amount, location, date, name), it did create a pdf file but when i print it, it doesn't align well, like for example the amount isn't exactly put in the box of the check, same goes for the amount in letters.


Guys i really need help in this, i'm so lost in this i've tried everything


this is the code of the program i did,
import tkinter as tk
from fpdf import FPDF
import num2words

def generate_cheque():
amount = amount_entry.get().replace(" ", "")
amount_parts = amount.split(".")
amount_in_letters = num2words.num2words(int(amount_parts[0]), lang='fr').replace("virgule", "comma").replace("zero", "")
amount_in_letters += " dinars algeriens"
if int(amount_parts[1]) > 0:
amount_in_letters += " et " + num2words.num2words(int(amount_parts[1]), lang='fr').replace("virgule", "comma").replace("zero", "") + " centimes"
location = location_entry.get()
date = date_entry.get()
company_name = company_name_entry.get()

# Convert dimensions from inches to points
width_in_inches = 8.5
height_in_inches = 3.5
width_in_points = width_in_inches * 72
height_in_points = height_in_inches * 72

pdf = FPDF(unit="pt", format=(width_in_points, height_in_points))
pdf.add_page()
pdf.set_font("Arial", size=12)

# Add date
pdf.set_xy(480, 150)
pdf.cell(0, 10, txt=date, align="R")

# Add amount in numbers
pdf.set_xy(450, 50)
pdf.cell(0, 10, txt=amount, align="R")

# add location
pdf.set_xy(400,150)
pdf.cell(0,10, txt=location, align="L")

# Add amount in letters
pdf.set_xy(110,70)
pdf.multi_cell(0, 10, txt=amount_in_letters, align="L")

# Add company name
pdf.set_xy(50, 120)
pdf.cell(0, 10, txt=company_name, align="L")

# Save the PDF
pdf.output("cheque.pdf", "F")

result_label.config(text="Cheque generated successfully!")

root = tk.Tk()
root.title("Cheque Generator")

amount_label = tk.Label(root, text="Amount (000 000 000.00):")
amount_label.pack()
amount_entry = tk.Entry(root)

Salt-Stack: Looking for a neet way to enforce a state only if a minon has seLinux installed

I have code that installs a custom seLinux module. In my fleet of minions there's Fedora based systems (with seLinux installed) and Debian based ones (without seLinux). On the latter the module/installing state should not be used and I am thus looking for a way of retrieving a neat answer to the question "is seLinux installed on this system?" (NOT "is seLinux enforcing on this system?") to use in a corresponding jinja2 if clause.


Attempts that have me despairing are:



* there appears to be no state in salt querying whether a given binary is on the $PATH - checking for sestatus is what I was after here.

* salt.states.selinux is not available on systems devoid of seLinux, so it's functionality does not help.

* I could not find any salt functionality to query for the local availability of something like salt.states.selinux (see above) either.






Any hint on how to go about this is appreciated.

Unable to calculate pod specific utilization of the resource through PromQL

I am calculating the namespace specific resource utilization which includes request and resource for cpu and memory and also doing the same for pod specific data.


When I am trying to aggregate the data based on pod to namespace level it is not matching the data directly driven by namespace filter.


I want the pod specific data which matches the namespace data when got aggregated.


For namespace specific data I am using below four queries. (Which is giving me correct answer)

{"cpu_usage": f"sum_over_time(namespace:container_cpu_usage:sum{{namespace='{namespace}'}}[1d])",
"cpu_request":f"sum_over_time(namespace_cpu:kube_pod_container_resource_requests:sum{{namespace='{namespace}'}}[1d])",
"memory_usage":f"sum_over_time(namespace:container_memory_usage_bytes:sum{{namespace='{namespace}'}}[1d])",
"memory_request":f"sum_over_time(namespace_memory:kube_pod_container_resource_requests:sum{{namespace='{namespace}'}}[1d])"}



For pod specific data I am using below four queries. (When I aggregate this queries using sum (query) by (namespace) the result is not matching the above queries' readings.)
{"cpu_usage": f"sum_over_time(pod:container_cpu_usage:sum{{namespace='{namespace}'}}[1d])",
"cpu_request": f"sum_over_time(kube_pod_container_resource_requests{{namespace='{namespace}', resource = 'cpu'}}[1d])",
"memory_usage":f"sum(sum_over_time(container_memory_usage_bytes{{namespace='{namespace}', container!='POD', container!=''}}[1d])) by (pod)",
"memory_request": f"sum_over_time(kube_pod_container_resource_requests{{namespace='{namespace}', resource = 'memory'}}[1d])"}



tl;dr


I want the same data as I am getting for the whole namespace but I want to segregate the usage and request for the specific pods.

Packing, unpacking and storing parameter pack in a tuple in c++ 17

I have a function pointer and parameters, and I'd like to save these and potentially modify them and call the function with them.


I've seen parts of this answered however I'm unsure how a complete solution would look like, I apologize, but I don't really understand parameter packs, and how they relate to tuple.


Here's bits of my code that I'm trying to make work together:


I have this which is basically just calling the function, I think this can be used to save the call into the "callable" structure, to make an interface.


from this question:
C++ generic function call with varargs parameter
template
auto call(R(*function)(Args...), Args... args) -> typename std::enable_if::value, R>::type {
return function(args...);
}

template
void call(void (*function)(Args...), Args... args) {
function(args...);
}



And this structure which should store the parameters and the function pointer. (thanks to RaymondChen for pointing out how it should be correctly)
template
struct callable
{
R(*function)(Args...);
std::tuple params;

callable(Args... argv):
params(std::make_tuple(argv...))
{}
};



I'm still unsure how I would actually call back the function with the tuple, as far as I understand I should somehow turn the tuple back to Args... and then simply call it.


What I'm trying to achieve:




* Save a call to be used later on

* Create my own call and fill it with my own parameters, from a running app.

* Read out saved parameters to do some manner of debugging.

get-service needs local account - how to consolidate report

I have a list of computers and I can only use the local account (user1) for each computer to get a list of services. I'm looping through the computers and using get-service but as you can see I have to title each section with the computer name. I was wondering if I can consolidate this into one list with computer name attached to each service.
$computers =
@"

$ServerUserId = "_$\user1"
$ServerPassword = ConvertTo-SecureString -String 'complexpassword' -AsPlainText -Force

Adding Real Time Chat to Laravel Using Reverb & Vue

---



Laravel, the web artisan's favorite PHP framework, has just got a whole new powerful tool in its arsenal: Reverb. Among the official packages of Laravel, this WebSocket server application would seamlessly let you integrate real-time features in your Laravel-based applications, thereby taking interaction to a whole new level.


What is Laravel Reverb?




Reverb acts as a mediator between your Laravel-based application and its users. It establishes two-way, real-time communication based on WebSockets technology that allows web pages to receive updates on the server without a complete page refresh. This means that your users experience your application more dynamically and responsively.


Key Features of Laravel Reverb




Blazing Speed: Provides outstanding performance for real-time information with no lags.


Scalability: Grow with your applications to handle increased user traffic.


Seamless Integration: It works with broadcasting features added to Laravel and Laravel Echo to make development simple.


Push Updates: Push updates, messages, or events to clients to share your information instantly.


Built-in Security: Data encryption and authentication assurance for security communication


Adding Laravel Reverb to Your Chat Project




With Laravel Reverb, you can build dynamic chat applications. The messages are posted instantly, making users involved comprehensively. Here's a breakdown of the steps involved:


Step 1: Setting Up Your Laravel Project:






*


Ensure you have a Laravel application set up (version 11 or above is recommended).


*


If you're starting fresh, use composer create-project laravel/laravel your-chat-app-name.






Step 2: Install and Configure Reverb:




Install Laravel Reverb by running the following command:
php artisan install:broadcasting



Once you’ve installed Reverb, you can now modify its configuration from the config/reverb.php file. To establish a connection to Reverb, a set of Reverb “application” credentials must be exchanged between the client and server. These credentials are configured on the server and are used to verify the request from the client. You can define these credentials using the following environment variables:
BROADCAST_DRIVER=reverb
REVERB_APP_ID=my-app-id
REVERB_APP_KEY=my-app-key
REVERB_APP_SECRET=my-app-secret



It also automatically creates echo.js in the resources/js directory.
import Echo from 'laravel-echo';

import Pusher from 'pusher-js';
window.Pusher = Pusher;

window.Echo = new Echo({
broadcaster: 'reverb',
key: import.meta.env.VITE_REVERB_APP_KEY,
wsHost: import.meta.env.VITE_REVERB_HOST,
wsPort: import.meta.env.VITE_REVERB_PORT ?? 80,
wssPort: import.meta.env.VITE_REVERB_PORT ?? 443,
forceTLS: (import.meta.env.VITE_REVERB_SCHEME ?? 'https') === 'https',
enabledTransports: ['ws', 'wss'],
});



Follow the Laravel documentation for configuration steps specific to your application server
https://laravel.com/docs/11.x/reverb />

Step 3: Running a Server




You can launch the Reverb server by using the reverb:start Artisan command:
php artisan reverb:start



By default, the Reverb server will be started at 0.0.0.0:8080, which makes it accessible from all network interfaces.


If you want to set a specific host or port, you can use the –host and –port options when starting the server.
php artisan reverb:start --host=127.0.0.1 --port=9000



You can also define REVERB_SERVER_HOST and REVERB_SERVER_PORT environment variables in your application’s .env configuration file.


Step 4: Setup Database




Open your .env file and adjust the settings to set up your database. Here’s an example using SQLite for simplicity:
DB_CONNECTION=sqlite
DB_DATABASE=/path/to/database.sqlite



You can create an SQLite database by simply running:
touch /path/to/database.sqlite



For this demo, we’ll create five predefined rooms. Let’s start by generating a model ChatMessage with migration for a chat_messages table.
php artisan make:model ChatMessage --migration



To make it simpler, only create name attributes for this model and migrate it.
Schema::create('chat_messages', function (Blueprint $table) {
$table->id();
$table->foreignId('receiver_id');
$table->foreignId('sender_id');
$table->text('text');
$table->timestamps();
});

php artisan migrate



Now, let's add the necessary relationships in the ChatMessage model. Open the ChatMessage.php file in the app/Models directory and update it as follows:
