On November 29, I’ll be at Zig Day Stockholm. I look forward to meeting other Zig enthusiasts there. zig.day/europe/stock...

I just published c7.se/reviving-a-q... where I document the experience of getting my old web server up and running again.

Cool, I've opened a PR now where I add myself and the fp8x8 app. Sidenote; It sure is a small world when I'm acquainted with both @deadprogram.com and Olle W.

(Jag testade att ladda ner de 49 böcker jag köpt från Amazon, och det funkade iaf. YMMV)

Jag bråkade ihop ett litet proof of concept här: gist.github.com/peterhellber... Vilket är en funktion man kan köra i sin Web Developer console på sidan www.amazon.com/hz/mycd/digi... för att ladda ner första boken i listan.

Naturligtvis är varken "More actions" eller "Download & transfer via USB" faktiskt länkar i HTML:en.. nästan som om de inte vill att man ska automatisera :)

Peter Hellberg @c7.se · 19/02/2025

Jag antar att @bildarkivet.org syftar på "Starting February 26, 2025, the “Download & Transfer via USB” option will no longer be available. You can still send Kindle books to your Wi-Fi enabled devices by selecting the “Deliver or Remove from Device” option."

Note that in the screenshot, orange is used for the "me" color, black for the "peer" and yellow for "combined".

It is a bit fiddly, but it is possible to run two instances of the @fireflyzero.bsky.social emulator, and have their respective inputs synced.

Two instances of firefly-emulator running my peter.input-test rom, in sync.

Det ska vi nog kunna ordna ska du se.

Peter Hellberg @c7.se · 18/02/2025

It seems like the current @fireflyzero.bsky.social emulator is consuming >100% CPU doing nothing really, which is a bit unfortunate. Let's hope it can be tweaked somewhat to work better on low end hardware. (like my P1000 GPU)

I've pushed fixes to the `ff.Angle` type, wrote some test cases for it, and also a small example where I'm using `ff.drawArc` to draw some rotating colors. Source code available from play.c7.se/ff/rot/

ff.Arc showing eight 45 degree slices colored from the default Sweetie 16 palette.

Really nice how convenient @github.com makes it to have static content published on Pages (`.github/workflows/static.yml` was generated for me). I am now publishing generated @ziglang.bsky.social documentation for `ff` on peterhellberg.github.io/ff/ when I push changes to the module. ⚡

Peter Hellberg @c7.se · 17/02/2025

Fixed the getRandom() issue in `ff`, and naturally had to test it out by writing something using that function. Source code available from play.c7.se/ff/rng/

Ported another WASM-4 thing to @fireflyzero.bsky.social For this one I got to do silly things like; if (self.color == .white) { for (&bytes) |*byte| { byte.* = ~byte.*; } } img[0x6..0xE].* = bytes; Source code available from play.c7.se/ff/fp8x8/

Just ported a small WASM-4 demo I made a while back to @fireflyzero.bsky.social using @ziglang.bsky.social, fun stuff 🔥 Updated my `ff` module with conveniences such as: const pal: ff.Palette = .{ .black = 0x000000, .gray = 0x292929, .white = 0xffffff, .orange = 0xf7a41d, };

I have now published github.com/peterhellber... (and github.com/peterhellber...) which makes it trivial for me to get started working on @fireflyzero.bsky.social apps, maybe someone else finds a use for it as well ✨

Today v0.5.1 of the @fireflyzero.bsky.social emulator was released, which means I could finally use it :) (due to me being on Pop!_OS 22.04) What better then to start working on some @ziglang.bsky.social code to make it convenient for me to start hacking on some apps.

Peter Hellberg @c7.se · 06/02/2025

Got the @fireflyzero.bsky.social Input test ROM to work (pad input via WASD and buttons HJKL + Enter)

Peter Hellberg @c7.se · 05/02/2025

Started working on a rudimentary @fireflyzero.bsky.social emulator in Go using Wazero, Ebiten and my Gfx-library. - wazero.io - ebitengine.org - github.com/peterhellber...

Haha, yeah I realized after publishing the Gist.. which I've updated now to not mislead others :)

Peter Hellberg @c7.se · 05/02/2025

I should likely have used `zstd.ZipDecompressor` instead :)

000

Peter Hellberg @c7.se · 05/02/2025

The @fireflyzero.bsky.social ROM file format is a Zip archive compressed with Zstandard. For fun I wrote a small CLI in Go to extract these using the lovely compress module by @klauspost.bsky.social (Note that you could just as well use `firefly_cli import <file>`) gist.github.com/peterhellber...

This week I've looked at a few vector databases, and found Qdrant to be quite pleasant to get started with. (Qdrant in combination with Ollama and the LangChainGo library for some small experiments) - qdrant.tech/documentatio... - ollama.com - github.com/tmc/langchai... #golang

Peter Hellberg @c7.se · 04/12/2024

Wrote some code to generate a list of the 24 most downloaded 4 color palettes on Lospec. Then started hacking on a little #wasm4 cart in #Zig You can follow along over at: play.c7.se/w4-advent/ (Change day with ↕️)

A neat thing with Typst is that its compiler has a WebAssembly host (in which you can load plugins for use in your .typ files) I wrote a library to make building such plugins in Zig ⚡️pretty convenient: github.com/peterhellber...

Hey! Now with a valid handle, hopefully.
