So I’ve tried Mastodon, Pixelfed and didn’t like them. Mastodon is nice if you wanna ”tweet”, but that’s not for me. Pixelfed was dead.

I quit Meta because of tech bro fascism, and hated Twitter even before it was X because, let’s face it - nobody has ever changed their opinion on anything because of a Twitter conversation (I know I’m exaggerating, to get my point across). I was in Reddit for a few weeks, and the conversations there seem mostly friendly and constructive, but I decided I don’t want to have anything to do with social media corporations. Besides, I noticed I could scroll endlessly. And that’s not good for me.

Lemmy seems nice. There are still some topics I’m interested in that don’t have active communities, and I’m still learning on how to have my feed from multiple instances. But still, this is the way to go for me.

Against algorithms, against fascism, for free internet. Thanks for coming to my boring Ted talk and have a nice day.

EDIT:
This has worked, thanks for help:

Hi, so I've been using Fedora 41 GNOME since release with no issues at all and I've decided to do a new fresh install of Fedora 42 yesterday.

Everything seemed to run well but I've encountered this issue in games that after around 30min I get this weird stutter. Until then everything runs smoothly.

As you can see in the video the stutter only occurs during mouse movement or during camera movement with keyboard. Once the camera moves on it's own and just tracks the character the frametimes are perfectly flat so it does not seem like the fault is on the game but somethings off with the system compositor?

This happens with or without VSync, I've tried with and without VRR, I've tried chaning game settings and also different Proton versions... only thing that helps is to restart the game but then I'll have to do it once again in about 30min.

My suspicion is on the new triple buffering in new GNOME 48 but I have no idea how to turn it off to test.

Any suggestions?

Stutter issue - Fedora 42 GNOME

^YouTube

Update: Issue disappeared without doing anything. After just letting my computer sit turned off for a few hours I started it back up to troubleshoot. Now it works again. Something happened to break it and then to unfuck it again without any input from me. Something is unstable and I’m gonna try to figure it out.

Started my PC up today, logged in like normal, but my keyboard wont work after logging in.
Except for the calculator button. None of the keys will actually do anything. But logging in works normally.

Worked fine last night, no updates have run or anything. Where to start diagnosing this? In a way where I won’t need a keyboard?

Fedora 42 KDE

Edit: Keyboard works fine in a live environment on the USB I used to install yesterday. Tried a different keyboard on my main install, and that didn’t work either. So it’s not the keyboard itself at least

🧮 Decentralization Scoring System (v1.0)

This scoring system evaluates how decentralized and self-hostable a platform is, based on four core metrics.

📊 Scoring Metrics (Total: 100 Points)

Top Provider User Share (30 points): Measures how many users are on the largest instance. Full points if <10%; 0 if >80%.
Top Provider Content Share (30 points): Measures how much content is hosted by the largest instance. Full points if <10%; 0 if >80%.
Ease of Self-Hosting: Server (20 points): Technical ease of running your own backend. Full points for Docker/simple setup with good docs.
Ease of Self-Hosting: User Interface (20 points): Availability and usability of clients. Full points for accessible, FOSS, multi-platform clients.

📋 Example Breakdown (Estimates)

📧 Email (2025)

• Top Provider User Share: Apple ≈ 53.67% → Score: 4.5/30
• Top Provider Content Share: Apple likely handles >50% of mail → Score: 4.5/30
• Self-Hosting: Server: Easy (Leverage email hosting services) → Score: 18/20
• Self-Hosting: Client: Easy (Thunderbird, K-9, etc.) → Score: 18/20

Total: 45/100

🐹 Lemmy (2025)

• Top Provider User Share: lemmy.world ≈ 37.17% → Score: 12/30
• Top Provider Content Share: lemmy.world likely hosts ~37% content → Score: 12/30
• Self-Hosting: Server: Easy (Docker, low resource) → Score: 18/20
• Self-Hosting: Client: Good FOSS apps, web UI → Score: 18/20

Total: 60/100

🐘 Mastodon (2025)

• Top Provider User Share: mastodon.social ≈ 42.7% → Score: 11/30
• Top Provider Content Share: mastodon.social ≈ 45–50% content → Score: 10/30
• Self-Hosting: Server: Docker setup, moderate difficulty → Score: 15/20
• Self-Hosting: Client: Strong ecosystem (Tusky, web, etc.) → Score: 19/20

Total: 55/100

🔵 Bluesky (2025)

• Top Provider User Share: bsky.social ≈ ~90%+ (very centralized) → Score: 0/30
• Top Provider Content Share: Nearly all content on bsky.social → Score: 0/30
• Self-Hosting: Server: PDS hosting possible but very niche → Score: 4/20
• Self-Hosting: Client: Mostly official client; some 3rd party → Score: 10/20

Total: 14/100

🟥 Reddit (2025)

• Top Provider User Share: Reddit ≈ 48.4% → Score: 0/30
• Top Provider Content Share: Reddit hosts a significant portion of user-generated content → Score: 0/30
• Self-Hosting: Server: Not self-hostable (proprietary platform) → Score: 0/20
• Self-Hosting: Client: Some unofficial clients available → Score: 3/20

Total: 3/100

How Scores are Calculated

🧑‍🤝‍🧑 How User/Content Share Scores Work

This measures how many users are on the largest provider (or instance).

• 100% (one provider): If one provider has all the users, it gets 0 points.
• No provider > 10%: If no provider has more than 10%, it gets full 30 points.
• Between 10% and 80%: Anything in between is scored on a linear scale.
• > 80%: If a provider has more than 80%, it gets 0 points.

📊 Formula:

Score = 30 × (1 - (TopProviderShare - 10%) / 70%)
…but only if TopProviderShare is between 10% and 80%.
If below 10%, full 30. If above 80%, zero.

📌 Example:

If one provider has 40% of all users:
→ Score = 30 × (1 - (40 - 10) / 70) = 30 × (1 - 0.43) = 17.1 points

🖥️ How Ease of Self-Hosting Scores Work

These scores measure how easy it is for individuals or communities to run their own servers or use clients.

This looks at how technically easy it is to run your own backend (e.g., email server, Mastodon server) or User Interface (e.g., web-interface or mobile-app)

• Very Easy: One-command Docker, low resources, great documentation → 18–20 points
• Moderate: Docker or manual setup, some config, active community support → 13–17 points
• Hard: Complex setup, needs regular updates or custom config (e.g. DNS, spam) → 6–12 points
• Very Hard or Proprietary: Little to no self-hosting support, undocumented → 0–5 points

Every few minutes, when I'm playing 3d games (like minecraft or blue price) my fps drops to around 5-10, stays that way for about 10 seconds, and then returns to a normal framerate. This does not happen with 2D games. I don't play competitive games so it doesn't impact me a ton but I thought I'd report it here in case someone can solve the issue.

Title is quite self-explanatory, reason I wonder is because every now and then I think to myself "maybe distro X is good, maybe I should try it at some point", but then I think a bit more and realise it kind of doesn't make a difference - the only thing I feel kinda matters is rolling vs non-rolling release patterns.

My guiding principles when choosing distro are that I run arch on my desktop because it's what I'm used to (and AUR is nice to have), and Debian on servers because some people said it's good and I the non-rolling release gives me peace of mind that I don't have to update very often. But I could switch both of these out and I really don't think it would make a difference at all.

Hello!

So, I live on a bus. We travel around, it's pretty great. I don't have a laptop or a mailing address that works, so getting certain things done is difficult, and I have two things I need help with.

I installed a solar system a while back, with an older charge controller a friend recommended. I more recently upgraded the batteries to lithium irons. So now this controller requires reprogramming, and to do so you have to plug an RJ45 (pretty sure that's the name) into it, and probably download some shitty chinese spyware program to fiddle with it. Their newer models bluetooth and require an app of course.

The other thing is either much trickier or impossible, and while I've booted up dumpstered laptops with thumbdrive linux before (and found the homemade blowjob video, heh) I've no idea how to even go about fiddling with this.

It's a (shitty chinese) dash/backup/security camera system. It's been referred to as a 'pizza box' system by someone who hates money. It might have a wifi chip onboard, but I can't figure out it does or not.

I'd like to flash it to run linux, if possible, and put some actually useable video monitoring/porting/editing maybe programs on there. The current UI is unusable even when it's cooperating. Like if there were an accident, I'd just basically be bluffing. Sure the data's probably there, but it's in a format that won't register on any device I've plugged the SD card into. I need it to export to filetype I can use with an ipad, which is the only computer we have aboard.

If any of this sounds like a fun or interesting challenge, I can throw some dollars at you. Or trade work! We do auto/diesel/bicycle mechanic work, welding, sewing, leather and general handy shit.

EDIT: The bad solution is to unblock UDP port 5353 but the port has to be source port, not destination port. (--sport flag) See the now modified rules. The issue is that this is very insecure (see this stackexchange question and comments) but obviously better than no firewall at all because at least I'm blocking TCP traffic.

The proper solution (other than using glibc and installing nss-mdns package) is to open a port with netcat (nc) in the background (using &) and then listen with dig on that port using the -b flag.

port="42069"
nc -l -p "$port" > /dev/null || exit 1 &
dig somehostname.local @224.0.0.241 -p 5353 -b "0.0.0.0#${port}"

-A INPUT -p udp -m udp --dport 42069 -j ACCEPT

I want to setup iptables firewall but if I do that, it blocks multicast DNS which I need. I am using command

dig "somehostname.local" @224.0.0.251 -p 5353

*filter

# drop forwarded traffic. you only need it of you are running a router

# Accept all outgoing traffic

# Block all incoming traffic, all protocols (tcp, udp, icmp, ...) everything.

Deny all incoming connections with iptables?

I want to make some simple iptables rules to deny all incoming connections and allow outgoing. How can I do that?

Hi all. This is an update on my script extracting CRC32 checksum from the 7z commandline tool. The output should be similar to how the md5sum tool outputs, the checksum and the file name/path.

The initial version of this script was actually broken. It would not output all files if a directory was included (wrong counting of files through argument number). Also filenames that contained a space would only output the first part until the space character. All of this rookie mistakes are solved. Plus there is a progress bar showing what files are processed at the moment, instead showing a blank screen until command is finished. This is useful if there are a lot of files or some big files to process.

Yes, I'm aware there are other ways to accomplish this task. I would be happy to see your solution too. And if you encounter a problem, please report.

crc32sum:

(Note: Beehaw does not like the "less than" character and breaks the post completley. So replace the line cat %%EOF with or copy it from the Github Gist link below:)

\#!/usr/bin/env bash

if [[ "${#}" -eq 0 ]] || [[ "${1}" == '-h' ]]; then
    self="${0##*/}"
    cat %%EOF
usage: ${self} files...

Calculate CRC32 for each file.

positional arguments:
  file or dir       one or multiple file names or paths, if this is a directory
                    then traverse it recursively to find all files
EOF
    exit 0
fi

7z h -bsp2 -- "${@}" |
    \grep -v -E '^[ \t]+.*/' |
    \sed -n -e '/^-------- -------------  ------------$/,$p' |
    \sed '1d' |
    \grep --before-context "9999999" '^-------- -------------  ------------$' |
    \head -n -1 |
    \awk '$2=""; {print $0}'

New version for toarchive: gist.github.com/thingsiplay/88…

(I have added a new version of the script. The old one is renamed to 'toarchive-old'. The new script has some guard rails and more checks. Also original files can be removed automatically on success, like gzip does. But an option -r must be explicitly given here, like toarchive zip -r file.txt. Directories can be removed too, but the option uppercase -R is required here, as in toarchive zip -R my_dir. Have in mind this will use rm -r system command. Although some guard rails are in place to prevent massive fail, you should be very careful. Note that no file is removed, if -r or -R are not used at all.)

I always write little scripts and aliases that help me from time to time. I just wanted to share some of my newest simple scripts. There are probably better or easier ways to do, but writing and testing them is fun too. Both make use of the 7z command, a commandline archive tool. Posting it here, so anyone can steal them. They are freshly written, so maybe there are edge cases.

crc32sum:

(Update April 17, 2025: Note this is a new version that addresses some issues. The old version I had posted was broken.)

\#!/usr/bin/env bash

# Calculate CRC32 for each file.
if [ "${#}" -eq 0 ]; then
    echo "crc32sum files..."
    echo "crc32sum *.smc"
else
    7z h -bsp2 -- "${@}" |
        \grep -v -E '^[ \t]+.*/' |
        \sed -n -e '/^-------- -------------  ------------$/,$p' |
        \sed '1d' |
        \grep --before-context "9999999" '^-------- -------------  ------------$' |
        \head -n -1 |
        awk '$2=""; {print $0}'
fi

\#!/usr/bin/env bash

# Create one archive for each file or folder.
if [ "${#}" -eq -1 ]; then
    echo "toarchive ext files..."
    echo "toarchive zip *.smc"
else
    ext="${1}"
    shift
    opt=()
    stop_parse=false

    for arg in "${@}"; do
        if [ ! "${stop_parse}" == true ]; then
            if [ "${arg}" == "--" ]; then
                stop_parse=true
                opt+=(--)
                continue
            elif [[ "${arg}" =~ ^- ]]; then
                opt+=("${arg}")
                continue
            fi
        fi
        file="${arg}"

        7z a "${opt[@]}" "${file}.${ext}" "${file}"
    done

I'll bring you straight into my mind: I was scrolling throught the n-th depressing post of the ~~day~~ hour and I thought "If I answer that post/comment by #negativity, will other people be able to filter out this content using my answer?" If not, how could we build some sort of blocklist for people to curate there experience on the fediverse.

I know I can block key word like "politics" "Trump" "Elon" but sometimes it doesn't have a precised word yet use human can categorise it easily.

Upon upgrading from Fedora 41 to 42, I noticed that the USB tethering just doesn't work

networkctl recognizes the device as "wwan" now, instead of "ether". If I load up a previous kernel, USB tethering works normally.

This seems to be a change in the kernel, and probably won't be reverted in the future. What do I do?

You know what? Fuck this. I just backed my shit up and installed Debian. Still, please try to look into this, this could be a problem for many others
