Making a fake AirPrint printer. I have a Brother printer that has two printer trays, one manual tray (that takes variable sized paper) and a A4 tray. However, when printing from iOS, it doesn't have the full print preset dialog and it is impossible to print from the manual tray, nor is there a way to tell it I want print A6. Of course I insist being able to print A6 whenever, wherever I want with AirPrint and accept…

How did you solve that last (expected port) problem?

(I've run up against that elsewhere, and couldn't get over the hump for iOS.)

It's extremely silly and inefficient but I love making random disco gifs: https://github.com/egeozcan/gifDisco

You should put an epilepsy warning before that large gif on your readme.

Thanks for the tip, very thoughtless of me. I added a warning.

I think it took me less than a day to ideate on and put Teeny (https://github.com/yakkomajuri/teeny) together, which is the static site generator that's powered my website for almost three years. I never touched the code again after that.

I rebuilt a Rhodes electric piano. Mine was in ok shape but the Rolex was ripped and some notes were hard to play. Turns out all the screws holding it together were bent. Bought some duratex roll on coating (similar to truck bed liner) and recovered it. Then went to the hardware store and bought replacement screws and bolts to reassemble the keyboard. Can’t believe how much better it plays now. Butter smooth.

Tolex?

I've never had the opportunity to write code for a compiler but it's something that's always been pretty interesting to me so I decided to write a little toy calculator:

calc("1 + 3 / 5")

It was a pretty fun project as you get to do some parsing/lexing, work out how to execute it (function ordering etc.) and then have lots of fun little avenues you can go down (brackets for specifying execution order, adding more functions, arbitrary precision maths etc.)

Scraping 6 million HN posts (out of a total of 40 million, 6M = some ~3 years of posts) and embedding them with openAI's text embedding models.

Making these full-text and fuzzy searchable with Postgres+pgvector, using reciprocal rank fusion to merge the two rankings. Very rapid query times on a 6 year old intel NUC; a kind of hn.algolia.com search only with added semantic search, not just text search.

Reducing the dimensionality for average per-user and per-submissoon vectors to 3D with UMAP, to see where my posts are located, in "hn discussion space". (expectedly, some users such occupy very specific clusters in discussion-space. There's a "dang telling you to please keep it intellectually stimulating" corner)

I should slap a frontend on the latter, host it somewhere not inside my own house and submit it, honestly.

Over four decades ago, when I was in my pre-teens, my family had a TRS-80 Model 1 (or was it a 3?), and I created a simple game for it in BASIC. In the game, a maze-like wall of blocks would be built as you watched, each block one of the system's super-chunky monochrome pixels. When the wall became almost, but not quite, impassable, you'd hit the space bar to halt the construction and begin the next phase of the game…

Brilliant game dynamic, and it’s so elegant that the human must solve the maze. The computer never does anything “heavy”!

Congrats! I remember when this came out. It was very cool. What did AWS do?

Have a look here. It spawned quite a thing! https://news.ycombinator.com/item?id=24799660

Wow! Thanks. I’m so glad I moved away from OSS licenses, to stop these vultures / parasites.
