Oppdatering av #Zopfli i #oxipng https://github.com/shssoichiro/oxipng/releases/tag/v9.1.5 dvs. bruke `-Z` / `--zopfli`, reduserte tida brukt på komprimering betraktelig.

Eks. en PNG gikk fra å bruke 70 s til 10 s.

Zopfli is *really* good at compressing PNGs

The Zopfli compression engine provides very good compression ratios.

Which packages are the 5% missing on #RISCV, what efforts are currently made and what need to be done:
https://lists.riscv.org/g/software/message/174

I would add after 1 or 2 weeks of testing that, Most JIT are missing, not only Lua (there is already a patch for RV32), PCRE, php engine, mb_strings (but they can all be used without it).

Other missing libs: libgsl25 (GNU Scientific Library), needed by Hugin, and Darktable (there is still rawtherapee). #ObsStudio is missing too.

On the sound design part, SuperCollider is missing.

On the (retrocomputer/arcade/console) emulator side missing are: openmsx, but mame, libretro (including bsnes, beetle-psx/vb/pce, desmume, etc...) are here. Missing in libretro are snes9x, and nestopia (closed source)

Alpha Zero の後継の MuZero じゃなかったのか。 #zopfli なんてのもあるのか。

同じ Google だけど、チーム対抗でもしてるのかな。
