gforce_deon How My Images Are Dithered

I like it! But i'm not so sure about the filesize safings mentioned.

Your dithered "truedinner.webp" has 189.166 bytes. The original image has 34.682 bytes with JPEG.

gforce_deon Handsum: An LQIP Image File Format

interesting! 147 bytes for 128x128 pixels are ~0.096 bpp (bits/pixel).

Everything above 153x153 pixels is too small (!) to count as LQIP (lighthouse).

The "normal" way would be to use a 0.05+ bpp WEBP-image as LQIP,

which has ~600 bytes, but looks MUCH better and is widely supported:

gforce_deon Perceptual Image Codec: What Matters in Practical Learned Image Compression

Yeah, thats slow - but the approach is at least interesting:

I tried to compare it with other encoders for the sample (girl/face painting): https://show.quicky.club/results/14/f8/f1/d8db84d57222d32db6...

The PICO-result claim to achieve 0.268 bpp (bit-per-pixel): Even webp (version 1) can do that good enough.

I understand, that one needs really advanced hardware to decode this. Not sure if this is worth the hassle.

gforce_deon Without benchmarking LLMs, you're likely overpaying

Wow - interesting how strong the differences are!

What seems missing: I can not see the answer from the different models. One have to rely on the "correctness" score.

Another minor thing: the scoring seems hardcoded to: 50% correctness, 30% cost, 20% latency - which is OK, but in my case i care more about correctness and latency I don't care.

gforce_deon DIY NAS: 2026 Edition

sorry for the german comment - ECC is mandatory!

Obligatorische Pastete: "16GB Ram sind Flischt, ohne wenn und aber. ECC ist nicht Flischt aber ZFS ist dafür ausgelegt. Wenn in Strandnähe Daten gelesen werden und es kommt irgendwie was in den Arbeitsspeicher, könnte eine eigentlich intakte Datei auf der Festplatte mit einem Fehler "korrigiert" werden. Also ECC ja. Das Problem bei ECC ist nicht der ECC-Speicher an sich, der nur wenig mehr als konventioneller Speicher kostet, es sind die Mutterbretter, die ECC unterstützen. Aufpassen bei AMD: Oft steht dabei, dass ECC unterstützt wird. Gemeint ist aber, dass ECC-Speicher läuft, aber die ECC-Funktion nicht genutzt wird. LOL. Die meisten MBs mit ECC sind Serverboards. Wer nichts gegen gebrauchte Hardware hat, kann z.B. mit einem alten Sockel 1155-Xeon mit Asus-Brett ein Schnäppchen machen. Ansonsten ist die Asrock Rack-Reihe zu empfehlen. Teuer, aber stromsparend. Generell Nachteil bei Serverboards: Die Bootzeit dauert eine Ewigkeit. Von Consumerboards wird man mit kurzen Bootzeiten verwöhnt, Server brauchen da oft mal 2 Minuten, bis der eigentliche Bootvorgang beginnt. Bernds Server besteht also aus einem alten Xeon, einem Asus Brett, 16GB 1333Mhz ECC-Ram und 6x 2TB-Platten in einem RaidZ2 (Raid6).6TB sind Netto nutzbar. Ich mag alte Hardware irgendwie. Ich reize Hardware gerne bis zum Gehtnichtmehr aus. Die Platten sind auch schon 5 Jahre alt, machen aber keine Mucken. Geschwindigkeit ist super, 80-100MB/s über Samba und FTP. Ich lasse den Server übrigens nicht laufen, sondern schalte ihn aus, wenn ich ihn nicht brauche. Was noch? Komression ist super. Obwohl ich haupsächlich nicht weiter komprimierbare Daten speichere (Musik, Videos), hat mir die interne Kompression 1% Speicherplatz beschert. Bei 4TB sind das ca. 40GB Platz gespart. Der Xeon langweilt sich trotzdem ein bisschen. Testweise habe ich gzip-9-Komprimierung getestet, da kam er dann schon ins Schwitzen."

gforce_deon OpenWrt: A Linux OS targeting embedded devices

You can build the image yourself, but have to switch off some packages or features - otherwise the image (linux-kernel + tools) is just too large or consumes too much memory. The original router has 8 megabytes RAM-memory and 2 Megabytes flash ("storage"). You can boot a recent kernel 6.16.5, but with 8mb there is not much left to work with 8-)

gforce_deon Prediction-Encoded Pixels image format

Thanks for making that clear. But is it worth the hassle?

https://nigeltao.github.io/blog/2021/fastest-safest-png-deco...

PNG decoding seems to be fast enough:

  tree1    - PEP =  0.412 ms PNG = 0.25 ms
  font     - PEP =  0.602 ms PNG = 0.663 ms
  nz_scene - PEP = 32.121 ms PNG = 3.069 ms

Anyway, PEP is interesting!

gforce_deon Prediction-Encoded Pixels image format

I really needs more benchmarks, especially decompression time. Also the sizes are interesting for very small images, but for real images, there are maybe better lossy variants:

  nz_scene - PEP = 73.542 bytes,
       lossy-PNG = 43.557 bytes,
      lossy-WEBP = 26.654 bytes,
  lossy-mozcjpeg = 15.716 bytes

So it's not about filesize here, it must be decompression speed.

gforce_deon Launch HN: Reality Defender (YC W22) – API for Deepfake and GenAI Detection
