And I was wondering why it's "so warm" in the living room compared to elsewhere in the house...

Vyšiel model Qwen3, prvý mysliaci model "na domáce žuvanie" s rozumnou podporou jazykov iných ako angličtina a čínština. Ešte to nie je úplne ono, ale už je to skoro použiteľné. 8B model v Q4_K kvantizácii sa pohodlne zmestí na 8GB grafickú kartu.

Postrehy:

- "myslenie" prebieha v angličtine
- výstup je v "slovenčine", ale gramatiku ešte úplne nezvláda a mnohé slová sú "novotvary", predpokladám z iných slovanských jazykov
- má tendenciu sa zacykliť

#3dprinting supports question:

Any tips/tricks on setting up supports in a slicer such that:

a) they actually support the print
b) are not a major PITA to remove

I had to spend an hour with the cutters just to get the supports out. Often I had to tear them from the print, fearing I'd damage the 10h print.

The same image, this time encoded with libx265.

10Mbit still seems like enough to encode the video without significant loss of quality.

I guess the Camera app video bitrate is so high just to make sure no one has opportunity to complain about "bad video quality".

Encoding with libsvt-av1 at various bitrates, pixel-peeping at a close-up crop during a high-movement scene.

I would be fine with 5Mbit (6x saving) and I can't see any difference at 10Mbit (3x saving).

I need to re-do this exercise with hevc.

Why was I disconnected on all my devices at home? Thankfully I have another way in, otherwise I would have been locked out with no way to fix it.

This is not a way to maintain trust...

The videos my Pixel 8a takes are nice and all, but why the hell do 10 seconds of 1080p HEVC compressed video take 40MB?

If I want to take a few minutes of video, that's hundreds of MB, at this rate I'll have to consider a Storinator build soon...

The idea behind the S4 non-planar slicer is super interesting and simple in hindsight - take a model, deform by in-model distance from base plate, slice it using a regular slicer and then deform back.

I wonder how long before this gets from "diy r&d" to consumer printer space.

I dusted up my old #RaspberryPi 3 with the HQ camera, put it on my window, pointed at the train track in front of my house, and set up Onlytrains [1]

The trains only travel once an hour so debugging required a lot of patience. Now I'll have visual proof of train timeliness.

My first experience with #sqlite3 (well, #Sqlite then)

~2005 I had an mp3 player with a mini HDD (yes, hard drive [1]) that only allowed uploading music via a tool. I managed to find the files on the drive, but their names were "mangled" (e.g. 18274521.mp3)

I found a weird looking file that looked like it might contain some interesting data with "sqlite" at start of hexdump. I found sqlite online and managed to find the way to map the file names back to metadata.

#arch #linux #gaming experience

After the failed attempt at remote play yesterday, I connected the xbox360 controller directly to the desktop. Nothing.

Reading the wiki I learned that I need the "xpad" module. `modprobe xpad` failed: module not found. Why? It turns out that the last time I updated the system, the kernel was updated too and I didn't reboot. So another `pacman -Syu`, wait for 1GB download over ADSL and reboot.

By the time I was done, I ran out of time for play. Maybe next time?

Once every blue (wolf/pink/whatever) moon I get a chance to actually play some games.

I tried playing Beam.NG on my old laptop on a big screen TV using #Steam remote play. Some software update broke the linux video en/decoding.
