@raunofreiberg hi!

13th rewrite. roast away

[rustam @frixaco]

let me do some clean up..

[rustam @frixaco]

compared to letting agents find and book hotels or flights for me, this seems like the better use case

made a little travel companion for my upcoming trip so everything’s in one place (and my family can see where i am without me texting every update):

- all the bookings, tips, and random notes in one spot
- day-by-day + rough hour-by-hour itinerary (adding alt routes as i go)
- private link so they can check the map / current plan
- weather, walking distances, and rough spend so i’m not opening five other apps

still polishing it but already nicer than the usual mess of notes + google docs + screenshots

@justinskycak "never do things half-assed. always use your full-ass"

one of my favorite quotes

@zack_overflow and it’s actually fun too

now we have Dots

with computer access, tailscale, and computer use, i can pretty much do anything from my phone!

[rustam @frixaco]

my favorite ChatGPT / Codex feature by far these days is being able to connect all my machines and control any of them from whatever device i’m using

[rustam @frixaco]

another little but very useful feature is being able to connect multiple Gmail accounts

(btw, both of which are missing from Claude)

fixed jagged lineart in my WebGPU Anime4K port. Lines looked rougher in the browser than in mpv at the same size.

turns out mpv’s libplacebo renderer uses linear sampling inside shader passes. I was using nearest-neighbor. switching to linear made the edges much smoother.

continuing work on my anime player in 4K in the browser.

last time i had the Anime4K shaders ported to WGSL and image upscaling working.

been working on the mkv side since:

- wrote custom matroska (mkv) parser in TS from scratch.
- reading local files or fetching byte ranges from a URL, caching chunks and loading the next chunk ahead of time
- pulling video/audio packets out of MKV blocks, calculating their timestamps and passing them to WebCodecs for decoding
- fixed color space issues
- bunch of optimizations to comfortably stream and upscale at 30+ fps

currently working on audio decoding and playback

[rustam @frixaco]

made an MCP for Ableton docs.

under the hood:
- SQLite FTS5/BM25 + local BGE embeddings
- rank fusion + MiniLM cross-encoder reranking
- overlapping text windows with heading context
- screenshots linked to exact text positions and nearby explanations
- actual image output over MCP, cached locally

plus 100-question benchmark to test search quality.

now trying to shrink the 300 MB (lol) download and make setup easier. keyword-only search and a smaller reranker both missed more supporting evidence. looking for a smaller setup that keeps retrieval quality.

OR i could spend that time actually reading the manual 🤔

update:

audio playback is working in the player!

- extended my matroska parser to handle laced blocks — multiple audio frames packed into a single block, each needing its own timestamp derived from the codec's samples-per-frame
- decoding audio with WebCodecs alongside video, scheduling through Web Audio
- hunted down a bug that made audio choppy: the decode loop slept a full second every time its queue filled up, so playback was fed at ~0.75x real time. one line fix, now the schedule runs ~60s ahead

video and audio play together now.
next: keeping a/v in sync over long playback

@_coenen this should've blown up

@justinmk thank you (and every contributor) for the work on neovim 🫡

30min walk solves everything

using KittyLitter and Codex (/goal) to migrate my music playlist on YouTube with 700+ songs to Apple Music

can't imagine doing this manually, probably would take me days...
