I just finished making a site, it has multiple ways emails are stored, I made a n8n workflow that gets the stored emails, checks if it has not been added onto a spreadsheet before, deduplicates it, then adds it to a spreadsheet. This workflow runs anytime a new email is submitted. This is my first time using n8n, is this dangerous? in the sense that having a n8n workflow that can be triggered directly by users, can it cause massive usage spikes in memory, etc very easily when its dependent on what a user can do? even if i ratelimit it, because I dont know the overhead n8n has, it takes a minute for the workload to finish also.

This is like a bunch of months late, but I am curious what people here thinks about steams new AI disclosure policy, which I think requires you to disclose or refrain from making AI content that is consumable, e.g the player sees and interacts with, whereas anything on the backend does not need to be disclosed, I know people are upset steam didn't push for a complete disclosure, but imo I agree with this approach, if anyone uses it for asset generate, i think thats prohibited given they previously took down a game for potential copyright violations, but for things you can interact with, those are like the first thing that can appear as bugs which could very quickly fill steam up with slop/buggy games, but for stuff less visible, I don't know, I guess wont matter as much? I worked on a few singleplayer games in the past (nothing on steam, also i did not use ai then). So I don't know is it an important distinction? I don't think i would be in favor with steam forcing people to disclose ALL uses of AI, like if its used appropriately like a tool, because too alot of people its all the same with no nuance, but thats just my opinion.

In other very late news, pre-generated content and live-generated content is an important distinction with steam, with live-generated having much more scrutiny and being banned for any 18+ content, this makes sense for me, I don't think anyone would disagree with this, but if anyone has any thoughts on this I am curious on what they are.

Is there any good courses that cover the more technical aspects of backend development? Here are some examples, not even limited to this, but I want to hear more than the basics and also some security things to look out for in like a yt video or something, potentially includes, CORS, Cookies, JWT, server side sessions, server side rendering, websockets, server side events, html patterns (e.g the backend returning html components to be place into the browser). Status Codes, GET and POST, GRPC, file transfers.

I could not fit everything i wanted to ask in the title, and the title probably needs some explanation. So to preface, I dont use AI code much, I have several projects which I taken effort to have 0% AI code, but I was wondering, because I do have certain tools, e.g a timetable editor supposed to make a timetable in a specific format i liked, or something that generates or give me a links of docs in a specific way, that I had generated, I also had projects which I tried using it for snippets, boilerplate and explanations. But I was wondering, where would be like, the best balance between human and AI code be, or rather how would you reclaim it in a sense, or improve your learning while also being efficient or also be knowledgeable enough about your code that you are a suitable person to maintain it.

Like, is it the second you read such code and try to understand it, you have the understanding but you completely lost most learning? Also would you potentially be locked into bad design choices by AI. What if you just looked at the inputs of the programs or the outputs and tried to recreate from that. Or what if you asked it what libraries to use, and you use those, would you have deprived yourself significantly of some level of understanding by having the design and architecture handing too you, even if you do the rest of the coding, and finally what if you memorized enough of the code to the point you can recreate it, and maybe apply it in different contexts a bit. Also would it be worth sharing if i do understand such code that was made by the AI, or would i be contributing to Slop. Basically, can you use it, but still at the end of the day be suitable to maintaining that code and etc.

Sorry if thats alot, anyways, curious to hear what people think, this could be useful for me in the future.

Currently I have only one laptop, I use it for everything and it has an nvidia gpu and a 11th Gen Intel(R) Core(TM) i7-11800H. I have a mode which disables the GPU which i use when i am out and about. However I want to minimize battery use to a significant degree, so which out of the three should I have on? power-profiles-daemon or autocpu-freq or tlp, which is better for battery performance? I know ppd is configurable via desktop, so i have kde set to power saving mode, but I still want better if possible, is there something more i can be doing with ppd or would autocpu-freq or tlp work better?

I am using rust, but this applies to many other languages, I get warnings like, dead code, unused variables, and etc, and while I remove most of them, there are some im not sure of, I like running my program and there being 0 warnings, or 0 warnings as i scroll down my code, so for things im unsure of, i mark them so the compiler doesn't put warnings there. I also add comments, starting with TODO:, it has some information about what to think about when i revisit it, also the todo's gets highlighed in my IDE with my extension, but is this bad practice?

I know this is application specific, but this relates to my overrall nix config i think, pipewire, wireplumber, all enabled. But I cannot record internal desktop audio, how do i fix this? is it a nix fix

I set the recording device to pipewire, I heard the host device needed to be set to pipewire or smthin, but only alsa shows up. If any logs are needed tell me.

EDIT: Not really solved but I found a script that worked for pw-record, now ideally I would like to fix it for audacity at some point, or just some other gui audio recorder

cat > ~/Music/record-desktop.sh << 'EOF'
#!/bin/bash
OUTPUT="${1:-$HOME/Music/Recordings/recording-$(date +%Y%m%d-%H%M%S).wav}"
pw-record --target 0 "$OUTPUT" &
PID=$!
sleep 0.5
pw-link bluez_output.30:50:75:16:40:A6:monitor_FL pw-record:input_FL
pw-link bluez_output.30:50:75:16:40:A6:monitor_FR pw-record:input_FR
echo "Recording to $OUTPUT (PID $PID) — press Enter to stop"
read
kill $PID
echo "Done! Saved to $OUTPUT"
EOF
chmod +x ~/Music/record-desktop.sh

EDIT (2): Found a better script which autodetects the monitor:

#!/bin/bash
OUTPUT="${1:-$HOME/Music/Recordings/recording-$(date +%Y%m%d-%H%M%S).wav}"

# Find the RUNNING monitor source
MONITOR=$(pactl list short sources | awk '/monitor.*RUNNING/ {print $2}' | head -1)

if [ -z "$MONITOR" ]; then
    echo "Error: no active monitor source found" >&2
    exit 1
fi

# Try to find a matching input (e.g. bluez mic matching same MAC as monitor)
MAC=$(echo "$MONITOR" | grep -oP '[0-9A-Fa-f]{2}[_:][0-9A-Fa-f]{2}[_:][0-9A-Fa-f]{2}[_:][0-9A-Fa-f]{2}[_:][0-9A-Fa-f]{2}[_:][0-9A-Fa-f]{2}' | head -1 | tr '_' ':')
MIC=$(pactl list short sources | grep -v monitor | awk -v mac="$MAC" '$0 ~ mac {print $2}' | head -1)

# Fall back to first non-monitor non-suspended source
if [ -z "$MIC" ]; then
    MIC=$(pactl list short sources | awk '!/monitor/ && /RUNNING|IDLE/ {print $2}' | head -1)
fi

echo "Recording desktop from: $MONITOR"
echo "Recording to: $OUTPUT"
echo "Press Ctrl+C to stop"

if [ -n "$MIC" ]; then
    echo "Recording mic from: $MIC"
    ffmpeg -f pulse -i "$MONITOR" -f pulse -i "$MIC" \
        -filter_complex amix=inputs=2:duration=longest \
        "$OUTPUT"
else
    echo "Warning: no mic found, recording desktop only"
    ffmpeg -f pulse -i "$MONITOR" "$OUTPUT"
fi

echo "Done! Saved to $OUTPUT"

EDIT (3): found something that includes my mic:

#
#!/bin/bash
OUTPUT="${1:-$HOME/Music/Recordings/recording-$(date +%Y%m%d-%H%M%S).wav}"

MONITOR=$(pactl list short sources | awk '/monitor.*RUNNING/ {print $2}' | head -1)

if [ -z "$MONITOR" ]; then
    echo "Error: no active monitor source found" >&2
    exit 1
fi

MAC=$(echo "$MONITOR" | grep -oP '[0-9A-Fa-f]{2}[_:][0-9A-Fa-f]{2}[_:][0-9A-Fa-f]{2}[_:][0-9A-Fa-f]{2}[_:][0-9A-Fa-f]{2}[_:][0-9A-Fa-f]{2}' | head -1 | tr '_' ':')
MIC=$(pactl list short sources | grep -v monitor | awk -v mac="$MAC" '$0 ~ mac {print $2}' | head -1)

if [ -z "$MIC" ]; then
    MIC=$(pactl list short sources | awk '!/monitor/ && /RUNNING|IDLE/ {print $2}' | head -1)
fi

echo "Recording desktop from: $MONITOR"
echo "Recording to: $OUTPUT"
echo "Press Ctrl+C to stop"

if [ -n "$MIC" ]; then
    echo "Recording mic from: $MIC"
    ffmpeg -f pulse -i "$MONITOR" -f pulse -i "$MIC" \
        -filter_complex amix=inputs=2:duration=longest \

flatpak run org.qbittorrent.qBittorrent
bwrap: Unable to open lock file /app/.ref: No such file or directory

I tried flatpak repair, with --user and --system, that did not fix it, and I did a system re-install, or rather reinstalled all the packages Nothing worked.

I am using nixos on unstable, recently I broke the nix part of my system, and was advised to do a re-install, I did a re-install which involved usb booting into nixos, and running a command to reinstall all the packages and rebuild in my nix directory, but afterwards, no flatpak is running. There is a possibility it broke beforehand and I didnt notice that, but i think it might have been after the re-install.

Flatpak version: 1.16.1

Distro: NixOS

Distro version: /nix/store/8hx8jwa24q6rkzhca9iqy5ckk9rbphi1-source

Architecture: x86_64

EDIT: Some flatpaks run but alot of them dont with the same error

EDIT (x2) SOLVED: I think the issue might have been the kde platform, as the apps that crashed were on kde platform 6.8 or 6.9, possibly some broken version, most likely the platform and bwrap didnt play well with nixos, these commands worked, I ran this for users (not system). Possible system might work, point is, I dont have the issue anymore.

This was talked about before, but the settings location that was mentioned to enable thumbnails on remote files and stuff has changed. I have a mount of my android system over mtp, and I cannot see any of the thumbnails, making it impossible for me to sort my stuff, some into hard drives and etc.

How do i enable seeing mtp thumbnails in kde, is there issues with just mtp thumbnails in dolphin or what alternative file manager or image veiwer I can use so i can see the thumbnails and relocate the images.

Hi, I want a nice easy-to-use graphical program which can show image thumbnails atleast, and provide an easy way to encrypt images, and ideally other files too. I heard of a few programs but some dont show images and some look a bit dated ui wise. Seeing image thumbnails is pretty much a requirement as it would be alot of swapping back and forth otherwise.

I am using KDE (and nixos), I dont think that matters much for what I want.

I heard varying things, I expect to have like 6-8 people come over in a few weeks and I want to set up lancache.net, but performance wise would it be horrible on a raspberrypi 4? or decent? I heard many things about lancache support on the raspberrypi, so I would like to hear about that too.

I do have a intelnuc as a secondary server but it would be harder to set up lancache on that, also I think I need to get a wifi card to set up a AP network, so would it make significant difference for a 16gb ram and modernish intel cpu to run it?
