i can here to understand sigaction(); function because im working on a project that called minitalk in 42 school so i was wondering how can i send a message from server to client using sigaction and other functions also use SIGUSR1 and SIGUSR2
Facing same issue here, I am using the custom component for the label, and I need to change some styles depending whether it is in the dropdown or in the tabs

okay so it seems like the problem was that i was trying to use VS Code and I should be using Visual Studio to run this project (i'm new to coding but to what i could gather VS Code cant properly run and gives this errors)
What have you tried so far to achieve this? Stack Overflow is meant for developers who are actively working through problems and need help refining or debugging their code. Not just a place to request ready-made solutions. It's important to show some effort and experimentation on your part.
Unrelated (kinda), question. Have you been able to change the textures of gltf (.glb) 3d object with sceneCore. In a similar way of what possible with previous 3d/Ar libraries used in android with kotlin like Sceneform?:
What I want to do (example):
An sphere without a mapped texture, plain color. Add a .PNG image as a texture that will be displayed in the sphere 3d object
Did you save the file? I also had the issue and i was trying to find what the problem was, just to find out i needed to just save the code before the terminal could read it ahah
i was wondering, did you succeed in that task? I'm currently stuck at the same task and i found recommendation about using "originator node" in thingsboard but still didn't succeed in the mission
Have you referenced the nuget package : System.ServiceModel.Primitives ?
The error implies either a missing using statement or a missing package reference, but it's difficult to help more without more detail. If adding the above library doesn't resolve it please provide more details about your application including what the project type is and what references you already have - but hopefully the above will sort it....
It seems your issue might be related to HTTPS ingress or TLS configuration in Kubernetes. Check out this guide on Deploying Teams tab apps to Kubernetes.

On 07 March 2025, I initiated a deposit of 500 INR Rupees to my Stake account wallet. Unfortunately, the amount has been debited from my Bank Account but has not been credited to my Stake wallet. Additionally, I have not received any refund in my bank account.
As it has been more than 26 day so kindly resolve this matter promptly by either crediting the amount to my stake wallet or refunding it back to my bank account.
(Being this my first interaction in Stackoverflow I hope I am not breaking any rules by confirming @AlexanderMashin's answer (in the comments section) with a detailed explanation from DeepSeek)
@AlexanderMashin pointed me to the right direction. I asked DeepSeek (DeepThink R1):
"Explain me why in Lua when modifying a copy of a table, made in a non deep copy method, for example by declaring a `local table_copy = table_original`, the original table changes too? Why does this happen?"
DeepSeek's answer confirmed points 1) and 4) of @AlexanderMashin's answer in his comments:
"1) Lua tables are passed by reference. You need to clone a Lua table if you want to change the copy without assfecting the original. 4) is the ulimate purpose of your code to create a table based on a template, in which metacharacters are replaceb by vaues from anothe table?"
Here is my question to DeepSeek:
"Explain me why in Lua when modifying a copy of a table, made in a non deep copy method, for example by declaring a `local table_copy = table_original`, the original table changes too? Why does this happen?"
And it's answer was:
"In Lua, tables are reference types, not value types. When you assign a table to a new variable using local table_copy = table_original, you are not creating a new table. Instead, you are creating a new reference to the same underlying table data in memory. This means:
Why Modifying the "Copy" Affects the Original
Tables are references:
When you write table_copy = table_original, both table_copy and table_originalpoint to the same table in memory.
Changes made via either variable will affect the same underlying data.
local original = {value = 10}
local copy = original -- Both variables reference the same table
copy.value = 20 -- Modify the shared table
print(original.value) -- Output: 20 (original is changed!)
Shallow copies are not enough for nested tables:
Even if you manually copy keys with a loop (a "shallow copy"), nested tables inside the original table will still be referenced, not cloned:
function shallowCopy(original)
local copy = {}
for k, v in pairs(original) do
copy[k] = v -- Copies primitive values (numbers, strings) but references nested tables
end
return copy
end
local original = {nested = {value = 10}}
local copy = shallowCopy(original)
copy.nested.value = 20 -- Modifies the original's nested table
print(original.nested.value) -- Output: 20
--------------------------------
Deep Copy Solves This
A deep copy recursively clones all nested tables, ensuring no shared references:
function deepCopy(original)
local copy = {}
for k, v in pairs(original) do
if type(v) == "table" then
copy[k] = deepCopy(v) -- Recursively clone nested tables
else
copy[k] = v -- Copy primitives directly
end
end
return copy
end
local original = {nested = {value = 10}}
local copy = deepCopy(original)
copy.nested.value = 20
print(original.nested.value) -- Output: 10 (original remains unchanged)
Key Takeaways
Assignment (=) does not clone tables; it creates a new reference to the same data.
Deep copies are required to fully clone all nested structures.
This behavior is intentional in Lua to avoid unnecessary memory duplication, but it requires awareness when working with mutable data."
Conclusion:
For me as a beginner this is a revelation, now I will act accordingly to this behavior of Lua tables that had me perplexed. "This behavior is intentional in Lua to avoid unnecessary memory duplication, but it requires awareness when working with mutable data." Thanks to @AlexanderMashin !

I want to reply to my own question just to update this post.
Sorry if i'm writing only after many days of silence, i readed all the suggestion and i want to say thanks to everyone!
I've experimented further with the integration of the library (and with many other things), i successfully used "Method 2" but i like to maintain my project as clean as possible so i didn't like that my folder/file tree was filled by numerous header and source file.
I ended up compiling the library into a shared library .so in my case and use it in my project in a much cleaner way (imho) basically using only dll and header file.
Warning keep appearing but for now it's fine like this.
If anyone else having similar question in more recent times. Try some open source apps like https://github.com/filebrowser/filebrowser and for the deployment on machine/pc https://www.kioskengine.io, it completely free (no Window needed, they have custom OS for that), and you can upload html/js app there or just use URL + you'll get extra stuff like interactions stats etc
Would it be possible for you to share a screenshot of the issue along with the relevant code snippets?
Did you use BottomSheetTextInput instead of the regular TextInput inside the Bottom Sheet?
Did you ever solve this, it's cooking me rn, I'm thinking of maybe some synchronisation placeholder or something of that nature, but I'm finding it very hard...
I'd love to get a reply if you're still alive or maybe still a programmer, mmmn maybe you've even abandoned this account who knows

अर्जुन एक छोटे से गाँव में रहता था। वह एक ऐसा लड़का था जिसके मन में हमेशा नए-नए विचार आते रहते थे। उसे कहानियाँ बनाने और लोगों को अपनी कहानियों से प्रभावित करने का बहुत शौक था। उसका सपना था कि वह अपनी कहानियों के माध्यम से दुनिया को एक नया दृष्टिकोण दे सके।
अर्जुन के गाँव में, जीवन सरल और शांत था। लोग अपनी रोज़मर्रा की ज़िंदगी में व्यस्त रहते थे, लेकिन अर्जुन की कल्पनाएँ उसे एक अलग दुनिया में ले जाती थीं। वह घंटों तक पेड़ों के नीचे बैठकर कहानियाँ लिखता रहता था, और उसकी कहानियाँ उसके गाँव के लोगों को भी बहुत पसंद आती थीं।
एक दिन, अर्जुन ने एक प्रतियोगिता के बारे में सुना, जिसमें कहानीकारों को अपनी कहानियाँ सुनाने का मौका मिलता था। अर्जुन ने इस प्रतियोगिता में भाग लेने का फैसला किया, और उसने अपनी सबसे अच्छी कहानी लिखी। उसकी कहानी एक ऐसे लड़के के बारे में थी जो अपने सपनों को पूरा करने के लिए सभी मुश्किलों का सामना करता है।
प्रतियोगिता के दिन, अर्जुन थोड़ा घबराया हुआ था, लेकिन जैसे ही उसने अपनी कहानी सुनाना शुरू किया, उसका आत्मविश्वास बढ़ता गया। उसकी कहानी ने सभी को मंत्रमुग्ध कर दिया, और उसे प्रतियोगिता का विजेता घोषित किया गया।
अर्जुन की जीत ने उसके गाँव में हलचल मचा दी। लोग उसकी प्रतिभा से बहुत प्रभावित हुए, और उसे एक प्रेरणा के रूप में देखने लगे। अर्जुन ने अपनी सफलता का उपयोग अपने गाँव के लोगों की मदद करने के लिए किया। उसने एक पुस्तकालय खोला, जहाँ बच्चे और वयस्क दोनों कहानियाँ पढ़ सकते थे और सीख सकते थे।
अर्जुन की कहानी हमें यह सिखाती है कि यदि हमारे पास सपने हैं और हम उन सपनों को पूरा करने के लिए मेहनत करते हैं, तो हम कुछ भी हासिल कर सकते हैं।
When i use these steps and create a conda environment, still do i need to install packages like sklearn and numpy , or do they come already installed in the environment?
When I have changed the hosting, then the issue is solved. But in the old hosting there hasn't any CDN or any cache plugin. Then why I changed the hosting the issue is solved.
In fact, I still don't know the specific cause of this problem. I just started to learn Swift (starting from the configuration of the development environment).
Next, I will try my best to show my current development environment and how to solve this problem:
I used helix to write rust and python code on this Mac mini, so I installed /Library/Developer/CommandLineTools.
Recently, I want to learn Swift (CLI program), and at the same time, I think xcode is too heavy for current needs, so I didn't install xcode.
Run swift --version and swift package init according to the Build a Command-line Tool, and they are running well.
The problem occurred when running swift run, and the error message has been displayed in the problem description.
At this time, I didn't make any additional installation(because swift --version and swift package init work well).
After many useless attempts, I reinstalled CommandLineTools, and the problem was solved.
From this, it should be possible to judge that CommandLineTools has provided the basic tools of Swift:
So how can you build an x64 setup.exe in VS that can read x64 registry keys? I have an installer that includes only x64 prerequisites because the app itself is x64 and will only run on x64 platforms. When the installer runs on x64 platforms (as an x86 process) it cannot detect whether the prerequisites are installed (ever). The install.log file always generates the same content "Unable to read registry value", even though the values are clearly visible in regedit or from the cmd line reg query. I've tried everything under the sun, including every possible registry key/value pair in the bootstrapper manifest, and I don't know of a way to force VS 2022 to build an x64 setup.exe (the configuration manager dropdowns are empty and the solution's TargetPlatform property has no effect). Is there a work around short of third-party apps?

It should go with NavigationLink, if I understand your question correctly. The proper pattern in SwiftUI to reset navigation and return to the welcome screen on logout when using deeply nested NavigationLink is to manage a NavigationPath.
With NavigationPath, we can use removeLast() to clear the entire stack. If possible, could you share how you are currently managing navigation in your code with NavigationPath?

very useful suggestions but I need to include one question here.
After generating string like in cell L55:
"<t><s></s><s>R</s><s>A</s><s>D</s><s>H</s><s>E</s></t>"
trying use:
=FILTERXML( L55, "//s" )
It provide to an error for first xml table "<s></s>"
#VALUE!
R
A
D
H
E
for some reason I need this first array element returned by FILTERXML as empty cell. Even if I use here single space like "<s> </s>" #VALUE! error appear too, only real content removing error. Same when try to use in the place of space "<s> </s>".
Can FILTERXML do it properly when something inside string is empty?
In my case I need empty cell at the beginning, not a space or any replacement.
