Earlier quoted context omitted.

That is so neat. I built something a little bit like this for a simulator of a 3D portal mill. Trying it on real wood got expensive fast so for debugging runs and trials of designs I would run a simulation where the toolbit would hack out the shape out of a three dimensional array of voxels. This was then displayed using a very simple engine built with PyGame. I got a lot of use out of that and it saved days (and a s…

That's an interesting application! I'm excited to see where these kinds of projects go now that we have so much computing power.

This thing I built was in 2006 or so iirc, here is a screenshot:

Apologies for the low resolution, I don't think I have a better one.

I'm working on an audiobook service (currently for myself) that will fill in major missing features for platforms like Audible.

- Ignore AI voiced books

- Show me unread books in series that I have in my library

- Experimenting with better search. I have experience with building semantic search systems and have been highly disappointed with Audible's extremely sub-par search capabilities. I want results that are actually based on books, authors, and narrators that I have already purchased, read, or listened to.

- Get automatic notifications when new books from authors and narrators that I subscribe to become available.

There's at least a few more gripes I want to address, but these are the high priority ones that come to mind right now.

I am creating a webapp to let screenwriters collaborate when writing their scripts. I have several friends in this industry and their tooling is either expensive, not localized for their market or straight away bad (I've seen terrible dataloss). I got some inspiration from linear and am building it on top of ruby on rails with CRDTs.

How is this different than using Google docs or something ?

Scriptwriting require specific formatting (set by Hollywood ages ago). Doing this in google docs is really painful. Besides that, people who work in this industry are already used to the format, so if you wanna pitch something to studios, they expect to be in industry format.

I have been working on my terminal editor, but I parked that for now -- https://github.com/bloomca/love. It is possible to load a file and edit it, copy/paste works, you can select text, etc. The next step is to integrate with the tree-sitter for syntax highlighting and then with LSP, but it took a bit more time than I wanted.

Another project of mine is to play music from my audio CDs by myself. I built a simple Rust library to read TOC and raw PCM data from a CD drive -- https://github.com/Bloomca/rust-cd-da-reader (works on Windows, macOS and Linux), and a ripper -- https://github.com/Bloomca/audio-cd-ripper, which rips all tracks and encodes it as FLAC and fetches metadata from MusicBrainz.

The next step is to play it. I looked into using cpal (https://github.com/RustAudio/cpal), but I feel like using low-level audio API for each platform is a better approach for learning.

I am working on Sweet Shop.

https://sweetshop.app

It's a digital comic book store. Letterboxd with a buy button. It's really fun. We've got a lot of great publishers signed, and a great team. It's such a thrill to work in a space where people work their ass off to create art, in spite of the fact that the rewards are minimal. Our job, we feel, is to make them more money to make more art.

I’m working on an ISBN database that fetches information from several other services, such as Hardcover.app, Google Books, and ISBNDB, merges that information, and return something more complete than using them alone. It also saves that information in the database for future lookups. Mostly because I’m working on a personal library management service called Shelvica to solve my own problems[1], and none of those serv…

Hey I'd like to learn more about what you're doing. I'm working on a tangentially related service but focusing on audiobooks. One big stumbling block I ran into early on was trying to find something close to a unified ISBN datasource.

If you're up for it, shoot me an email at charles@geuis.com.

Improving my 'Video game generator from photos'. The bottleneck of this kind of generator is 'how much time to obtain the video game". I managed on my last vacation (it's a side project) to reduced it to 2 hours. This is an example of one FPS made by my tool : https://free-visit.net/fr/demo01

Earth Meta Insights Since a few months back I am working on a side project to give a snapshot of the regional and global species and natural ecosystems. I use manual (me) and automated tools (web and literature search tools, llms, visualizers ...) to search, extract, organize and visualize ecosystem literature and data. A regional example of mountain gorilla's of Rwanda: https://www.earthmetainsights.com/emi-cards-go…

I appreciate what you're doing here. I think it's really important to have this kind of high level overview of these species. I have a little feedback based on clicking around the site.

When you click on a country in the map view(under Elephants, for example), I think the map still has focus instead of the card. So this means you can't highlight text, click on links, etc within the card. Also if you scroll using the scroll wheel, you end up zooming in and out on the map.

I wonder if it would be good to have a "see more" link or some such here, so you can view the same information in the card, but on its own discrete page for each country?

I’m building a daily word puzzle game with a twist! In Tiled Words you rearrange tiles to solve clues and rebuild a broken crossword. You can play a demo at https://tiledwords.com - it’s free and web based so it works on whatever device you’ve got. I’ll be officially launching on October 19th at the Portland Retro Gaming Expo. You can sign up to be notified on launch. Starting then there will be a new puzzle every da…

Cool idea. One suggestion is to allow a selection box to be dragged around a block of letters. Once selected, all of the tiles in the area could be dragged at once. That would reduce the frustration of having to move a large chunk of words around piece by piece. It would be better than the existing affordance, which moves the whole grid.

Thanks! I experimented with this but struggled making it feel natural on mobile.

I ended up implementing an alternate solution that I’m hoping solves for the same paint point.

My current dev build “merges” tiles when you connect them to complete a word. This allows you to move them as

I’m going to release a demo with that feature soon. My core playtesters seem to like it but I want to get more feedback on it from a larger group!
