Christoph Hellwig Steps Down From One Of His Kernel Roles Following Rust Drama in c/linux@programming.dev

Rust is a psyop

I have no idea how to use SwayWM in c/linux@programming.dev

I think the default mod key is the 'super' key (formerly known as the windows key). It might be alt actually, I don't remember. Super + 1-9 switches between workspaces, which hold your windows. Shift + super + 1-9 moves a window to another workspace. you can find more key bindings by viewing $XDG_CONFIG_HOME/sway/config (or wherever config files go on your system).

I think those are more interesting. I like seeing the process.

What are some good resources to learn to write very reliable/formally verifiable software? in c/programming@programming.dev

(Part 1) omg I can't believe this actually worked first try!

with open('input') as data:
    parts = data.read().rstrip().split("\n\n")

    updates = parts[1].split("\n")

correct_updates = []

    for rule in rules:
        return list(filter(lambda x: x.split("|")[0] == pg_num, rules))

def interpret_rule(rule: str) -> list[str]:
    return rule.split("|")

def interpret_update(update: str) -> list[str]:
    return update.split(",")

def find_middle_update_index(update: list[str]) -> int:
    num_of_elements = len(update)
    return num_of_elements // 2

for update in updates:
    is_correct = True
    for i, page in enumerate(interpret_update(update)):
       rules_to_check = find_relevant_rules(page, ordering_rules) 
       for rule in rules_to_check:

this took me so fucking long and in the end i just went for brute force anyway. there are still remnants of some of previous, overly complicated, failed attempts, like the hideous global removed. In the end, I realized I was fucking up by using remove() instead of pop(), it was causing cases with duplicates where the removal of one would yield a safe result to count as unsafe.

Weird behavior in python (tkinter) [SOLVED] (programming.dev)

I'm working on a little gui app that will eventually (hopefully) add a watermark to a photo. But right now I'm focused on just messing around with tkinter and trying to get some basic functionality down.

I've managed to display an image. Now I want to change the image to whatever is in the Entry widget (ideally, the user would put an absolute path to an image and nothing else). When I click the button, it makes the image disappear. I made it also create a plain text label to see if that would show up. It did.

Okay, time to break out the big guns. Add a breakpoint. py -m pdb main.py. it works. wtf?

def change_image():
    new_image = Image.open(image_path.get()).resize((480, 270))
    new_tk_image = ImageTk.PhotoImage(new_image)
    test_image_label.configure(image=new_tk_image)
    breakpoint()

with the breakpoint, the button that calls change_image works as expected. But without the breakpoint, it just makes the original image disappear. Please help me understand what is happening!

How to see CMUS logs / get info for bug reports (programming.dev)

submitted 1 year ago by Hammerheart@programming.dev to c/linux@lemmy.ml

2 comments fedilink

Sometimes my CMUS will randomly stop playing a track or it won't play the next track until I manually go in and hit c (for resume) or otherwise initiate playback. I would like to be able to see what happened before these instances so i could either fix my config or, if its a problem beyond the scope of my local environment, get info to write up a proper bug report with. Where can I find such logs? Would they be in the systemd journal or somewhere in /var ?

:s/ failed to find the ^M s (programming.dev)

submitted 2 years ago by Hammerheart@programming.dev to c/neovim@programming.dev

5 comments fedilink

So I just had an issue where my shebang lines weren't parsing properly for a python script I was attempting to execute. A quick google revealed that it was probably because I wrote the scripts on windows and now I was trying to run them on Linux (so happy i finally made the switch btw. using the computer is fun again!). So i took the advice I found and tried to run :%s/^M/ (using C-v, C-m to insert the escape character), and it failed to find any matches. I tried the same command in vanilla vi and it worked.

Is there some setting I don't have configured properly? I would prefer to be able to do this sort of thing within neovim.

Xclip is not talking to the system clipboard (Klipper) (programming.dev)

submitted 2 years ago by Hammerheart@programming.dev to c/linux@lemmy.ml

1 comments fedilink

If anyone could help me out with this, I'd greatly appreciate it. Basically, I can't ctrl + v to paste anything I pipe into the clipboard selection in xclip, and i can't xclip -o anything I copied with ctrl-c or ctrl-shift-c.

Maybe I want to paste a path into a neovim file. echo $(pwd) | xclip -i -sel c Now the path is in my clipboard, right? It sure shows up if i xclip -o -sel c!

But when I go into neovim and paste from the unnamedplus register, instead it pastes the last thing I copied in my browser.

if I want to copy the output of something from my terminal and google it, ctrl+v in the browser completely ignores my xclip selection.

i am forced to use the mouse and ctrl+shift+c in order to paste it into a search engine, like a caveman.

I hope I've done a decent enough job explaining the problem. It was most apparent earlier, as I was making a cronjob and I had to be explicit about file paths because i couldn't assume the working directory would be the directory of the script I was calling. I really wish I could have just echo $(pwd) | xclip -sel c; open neovim; hit p; see the path appear in my file.

I have a little clipboard icon in my system tray with my copy history, except none of the things I put in the clipboard selection with xclip -sel c or xsel -b appear there. I think that program is klipper, but I'm not sure.

I know there's a number of work arounds but still this kind of frustrates me. I think it has something to do with wayland and xclipboard not talking to each other. I am running wayland, KDE Plasma 5.27.5, and Debian 12.

Is there a simple configuration setting I can tweak, or do I need to find something to replace klipper or xclip? I have tried toggling the keep selection and clipboard the same and always save text selection in history settings in the plasma clipboard, no change. I tried two terminal emulators to no avail.

I will happily provide any more information if it would be helpful.

I feel like breaking my windows install was a rite of passage (programming.dev)

Lately ive noticed that i was wanting to do certain things on Windows that just seemed much easier and more intuitive on Linux, based in the OS specific solutions i would see to problems i encountered. And i was more frequently using software where Windows support seemed like an after thought.

A couple days ago i finally sat down and tried to install Mint. The installer didnt recognize my windows partition so it didnt offer any assistance. And a stroke of fate saw my internet connection dieing at the exact same time. Yes, i cant believe it either.

So i decided to live dangerously and just try to wing the installation with no outside help. It seems like creating a second EFI partition was not the right call. The install failed, and I couldn't get back onto windows.

I wound up just using a live ubuntu image for a few days while i wrestled with repairing the boot loader. I didnt succeed. Eventually i just made a windows recovery disk from my Desktop with an intact copy of windows, and had to reinstall windows.

Then i did manage to successfully install Debian, and ive been having such a great time with it so far. I feel like i probably didnt even need to keep a windows partition, especially since i could have just used my desktop if i REALLY needed windows. I havent had this much fun just using the computer since i was a kid.

UndoTree Plugin Not Working (programming.dev)

I'm new to vim and getting the hang of the configuration. I've gone through a couple of youtube videos giving a tutorial of setting it up with lazy.nvim. Now I am following ThePrimeagen's config, and UndoTree doesn't work.

The plugin is loaded and my config is properly sourced, but when I run run :UndoTreeToggle, I get this lovely error:

(E5108: Error executing lua: function undotree#UndotreeToggle[11]..<SNR>37_new[2]..41, line 6: Vim(echoerr):"diff" is not executable. stack traceback: [C]: at 0x7ff77ae89570)

I am running windows (currenty in the process of backing up my personal data so I can try out Linux without feeling too disconnected from my daily computer user). I did a little bit of google searching and checked the issues on github, unfortunately I couldn't find anything related to my problem. Any help would be much appreciated.

Why am I getting this unexpected arguments warning in python? (programming.dev)

I am working on user authentication in Flask. I have my User class, which inherits from db.Model (SQLAlchemy) and UserMixins (flask-login):

class User(db.Model, UserMixin):
    id = db.Column(db.Integer, primary_key=True)
    email = db.Column(db.String(100), unique=True)
    password = db.Column(db.String(100))
    name = db.Column(db.String(1000))

and I create a new User object during registration:

        new_user = User(
            name=request.form["name"],
            password=generate_password_hash(password=request.form.get("password"),
                                            salt_length=8,
                                            method="pbkdf2:sha256"),
            email=request.form["email"])

Since I inherited from UserMixins, I started to get an "unexpected arguments" warning from pycharm when I create new_user. can someone explain to me why that is? If I don't inherit from UserMixins, the warning goes away.

I can't log into pd in jerboa? (programming.dev)

submitted 2 years ago by Hammerheart@programming.dev to c/meta@programming.dev

So, it used to work just fine. Then jerboa became basically unusable due to some bug. That was a few weeks ago. I saw an update was available, so I thought to give it another try. It's much more stable after the update, and my lemmy.one account works just fine. But when I try to log in with this account on jerboa, I get an incorrect login error. I set the instance to "programming.dev" and I know I used the right credentials because my password manager filled them in, just like it does in the browser.

Any ideas on a cause or fix? It might be a jerboa issue but I don't get why it seems to only impact this instance.

[Solved] Help with spotipy (programming.dev)

I am trying to create a playlist with spotify and the spotipy library in python. However, I keep getting a "No token provided" error when making my API request. However, if I use the same token with a curl request, it works! Can someone please help. This is my code:

auth_manager = SpotifyOAuth(client_id=CLIENT,
                            client_secret=SECRET,
                            redirect_uri="http://example.com/",
                            scope=SCOPE,
                            username=spotify_display_name
                            )
token = auth_manager.get_access_token(
    as_dict=False,
    check_cache=True
)

sp = spotipy.Spotify(auth_manager=auth_manager,
                     auth=token
                     )
user_dict = sp.current_user()
user_id = user_dict["id"]
print(f"Welcome, {user_dict['display_name']}")


# SEARCH
# QUERY FORMAT: "track: track-name year: YYYY"

spotify_search_endpoint = "https://api.spotify.com/v1/search/"
test_query = "track:Hangin'+Tough year:1989"

search_parameters = {
    "q": format_query(test_query),
    "type": "track"
}

results = sp.search(q=search_parameters["q"])
print(results)

output:

{'tracks': {'href': 'https://api.spotify.com/v1/search?query=track%3AHangin%27%2BTough%2520year%3A1989&type=track&offset=0&limit=10', 'items': [], 'limit': 10, 'next': None, 'offset': 0, 'previous': None, 'total': 0}}

{
"error": {
"status": 401,
"message": "No token provided"
}
}

This is really frustrating! The authentication is working, otherwise the token wouldn't have been valid for the curl request. I must be doing something wrong with spotipy.

I made my first C program! (programming.dev)

I was looking over the first kata i did on codewars, and I thought it would be fun to try and solve it in C. The object was to return a string based on a boolean input. it took a lot of trial and error, googling, chat gippity, but I eventually got it to work. I am still focused on learning python, but I've had it in my mind that I should branch out once I've reached a competence plateau in python. I'm nowhere near that plateau yet, but this seemed simple enough to warrant the necessary investment in time to accomplish it.

// C:
#include <stdbool.h>
// FIRST EVER C PROGRAM
const char *bool_to_word (bool value){
// you can return a static/global string or a string literal
  if (value == 1){
  return "Yes";
    }
  else{
    return "No";
  }
}

I realize this is pretty trivial, but still, it's a milestone for me and I wanted to do my part to get the ball rolling on this community.
