Made this Vim rhythm game this past long weekend. I felt I didn't have any proper pressure to get faster at Vim motions while coding, so a rhythm game felt apt. Try it out!

Ive used firefox for a decade, theres only two features I want: uBlock origin on iOS (hard?) and PWA support on Desktop

Thanks for the kind words! As I briefly mention in my video, my teammate actually had guitar tabs going, with lyrics chords and even web scraping/search. I think a bit of refinement and better hardware and we'll get what you're looking for

I tried using lilypond actually but ran into an error that no one seemingly knew how to solve. Can try digging through my history if you're interested

Agreed! These glasses do look very normal - only tell is that at a certain angle you can see the green of the screen, and the part near the ear is a bit bigger (but easy to conceal with hair)

Thank you!

This would make the most sense, since MuseScore is notoriously litigious about usage and redistribution of their library/MusicXMLs, so a collaboration would be necessary to get a usable music catalog for smart glasses

If I were designing around this limit, I would put enough memory to be able to store a nice buffer of bitmaps in either direction and then do sends that don't change what's currently displayed. I feel like that memory probably exists, I just don't have access to the firmware sadly

Yeah, it's a big deal for sure, I was bugging Mentra all hackathon to try and lower it, and also reached out to Even for suggestions (which Mentra is implementing). Regardless, I made it work and next gen hardware, firmware and software are all definitely going to be better for bitmaps

Show HN: Sheet Music in Smart Glasses

Hi everyone, my name is Kevin Lin, and this is a Show HN for my sheet music smart glasses project. My video was on the front page on Friday: https://news.ycombinator.com/item?id=43876243, but dang said we should do a Show HN as well, so here goes!I’ve wanted to put sheet music into smart glasses for a long time, but the perfect opportunity to execute came in mid-February, when Mentra (YC W25)...

I use stirling-pdf for this, ran locally with

docker run -d -p 8080:8080 -e DOCKER_ENABLE_SECURITY=false --name stirling-pdf frooodle/s-pdf:latest

Lots of features, OP you should definitely check this out

Another huge time sink is rotoscoping, e.g. in my video I rotoscope the legs of the piano bench and its a cool effect but it took almost an hour for those few seconds. AI has come far here, but afaik there's no great, free workflow yet. Would love to Docker compose something on my computer, open a webapp, drag my clip in and export segmented videos.

For me, it's still easy to mess up for complex sections if I'm not peeking at the keyboard every so often. Its true that muscle memory takes over after you reach a level of familiarity but not quite to the extent of biking
Re:I put sheet music into smart glasses [video] on Saturday May 03, 2025 @09:30AM (#43878920)
A lot of the time is from the glasses themselves, but apparently Mentra talked to the Even CEO and next gen bitmaps will be much better

Thank you, the typewriter effect is surprisingly hard, requires a pretty complicated expression in after effects
Re:I put sheet music into smart glasses [video] on Saturday May 03, 2025 @09:26AM (#43878894)
Correct!

A fun first attempt I made at putting sheet music into smart glasses, collaborating with Mentra (YC W25)

I'm a (new grad) software engineer by trade, but for the last 8 months, I've been working on this amateur short film about impostor syndrome, which I think would resonate with a lot of you. At least for me, I was never the best programmer or mathematician in any class I took, but I managed to get to where I wanted to be regardless through hard work, sacrifice, and the support of my friends. I hope this film resonates with some of you! P.S. I can't make any money off of YouTube because of my TN visa, someone teach me how to get an EB2 visa
Re:Bad Apple but it's a 3Blue1Brown video on Sunday May 05, 2024 @01:41PM (#40266644)
I wanted to make a Bad Apple video and I decided to try out the software 3Blue1Brown uses to make his amazing math explainers. My scope crept unbelievably hard until I was revisiting my 4th year electrodynamics textbook to create one of the visuals, and the result looks pretty great in my opinion.
I actually tried using TSP to optimize the order of apples moved for a single frame, but what you sent seems like a much better fit (I'll bookmark it for the future). Either way, conveying all the moving information on a single reference picture is hard.
For the past two months, I've been working on making Bad Apple with apples. It had a bit of a hardware build but there was some really interesting software problems too so I figure this crowd might be interested :D (also someone is definitely going to tell me a better way I could have done it and I'm all for that)
Just played this with some teammates. Some feedback:

- There was 7 of us, so the text felt kind of slow. Being able to click to speed up would be nice, or change text speed.

- Quiplash rewarded creativity more I feel, the problem with this game is that lots of people have the same answer

"San Francisco police are cracking down on car break-ins using a bait car program meant to catch thieves red-handed." Neat.
I use side-loaded 4K Video Downloader: https://www.4kdownload.com/products/videodownloaderandroid-4.... Not a regular viewing client though.

I havent touched llm stuff because the barrier to entry felt pretty high. This has reduced the barrier so much if it works as promised.
