Building an iOS app for metronome sequencing to get faster at playing guitar and reaching "shred" speeds at different subdivisions/time signatures in a single sequence. Planning on adding accuracy indicators and scoring so rushing or dragging can be easily identified when finishing a saved routine. I.e., some post-routine metrics. I've been playing guitar for a little under 6 years and ran into the common problem amo…

When will it be done? Would like to try.

At least a couple more weeks. Hopefully less than a month out from now.

I have most of the UI done for sequencing. Workflows for speed building and metronome sequencing will be completely free, which is also a top priority for me to get out the door first.

After that Deus Ex remaster fiasco, I wanted to see how the famous Unreal 1 dithering technique would look on Quake's software renderer. Getting a clean build of it on Linux was fun in itself: https://github.com/klaussilveira/exp-quake

I can't take much credit for anything really, all of the meat came from Tim Sweeney himself: https://www.flipcode.com/archives/Texturing_As_In_Unreal.sht...

I miss the golden days of flipcode.

Everyone’s drowning in long articles, dense PDFs, and hour-long videos. I’m working on https://unrav.io , it lets you flip any article, paper, or YouTube link into the format you actually want (summary, mindmap, podcast, infographic, etc.) in one click. Right now I’m experimenting with a simple bookmarklet trigger instead of a browser extension. Curious: how do HN folks feel about bookmarklets in 2025, still viable,…

Very viable, please go this route!

Currently a one-man side project: https://laboratory.love Last year PlasticList discovered that 86% of food products they tested contain plastic chemicals—including 100% of baby food tested. The EU just lowered their "safe" BPA limit by 20,000x. Meanwhile, the FDA allows levels 100x higher than what Europe considers safe. This seemed like a solvable problem. Laboratory.love lets you crowdfund independent testing of s…

This is so incredibly important, well done. The problem of our food being steeped in plastic hits the news here and there, but it should be front and center in my opinion. Testosterone has been plummeting for decades and it scares the heck out of me. The hormone whose job is "form goals, shrug off failure, and try again!" is being destroyed and corporations are given a free pass to pump us full of phthalates and bisphenol. It's infuriating.

I'm working on Zettelgarden: https://zettelgarden.com.

It's a personal knowledge system. It's a zettelkasten with an LLM substrate. It uses LLMs to build a model of the theses, arguments and facts used in cards, and uses these to both summarize the information on the card and to automatically link cards together based on shared concepts.

Building an app where 1 pushup = 1 minute of scrolling allowed [1]. We've fiiinally started to grow and reached a whooping $30k in the last month!!

I was literally thinking about quitting in August. My motivation is now at an all-time high - some users have done >8k pushups :)

As always, the key has been the marketing (10M views on Instagram). But we have to improve the product to make people love it even more. So the roadmap is more full than ever.

Earlier quoted context omitted.

The UX is phenomenal. Easily in the top 1% of daily word puzzles. Love the concept, I'm sure it will do well at your launch!!

playlin.io is super cool! Nice job! I’ll submit my game there when it launches :)

Thank you! Happy to feature your game, I've played a _lot_ putting together Playlin so I have a pretty good sense of what's out there.
