I built a few python packages for my own use. The most notable one was created as an open source component for a government project where files needed to upload to S3 buckets without touching the local file system (for various reasons). The result was a S3 chunk uploader for Django apps. It also speeds up upload significantly for large files.

It's available here: https://github.com/uktrade/s3chunkuploader

Other packages are html meta tag parser (https://github.com/harel/metatron) and a python smtp wrapper (https://github.com/harel/strudelpy)

I've built a few over the years: - https://volt.fm - See, share and compare your Spotify stats - https://postsheet.com - Send emails to contacts in a Google Sheets or Airtable document - https://pikaso.me - Screenshots Twitter for sharing on Instagram - https://github.com/soheilpro/zsh-vi-search - Adds support for searching the current line (in normal vi mode) to zsh - https://github.com/soheilpro/catj - A better way…

Cool body of work!!! :)

Last year I built Recut[0], a native Mac app that helps speed up video editing by automating the rough-cut process. It finds silence, gaps, and pauses and removes them, creating a cut list that you can import into editors like ScreenFlow, Final Cut, Premiere and Resolve. Here’s the Show HN [1] from a couple months ago. I built it because I was making screencasts and cutting out silence + mistakes was 90% of my editin…

This solves a huge problem for me, and is easily worth three times the amount I paid for it. Thank you!

Awesome, thanks! Let me know if you have any feedback/feature ideas.

In 2013, I started https://webtorrent.io the first torrent client that runs in a web browser. It’s open source here: https://github.com/webtorrent I built it to make torrent technology more accessible to the masses. We’re still actively building it and we even have a slick desktop app that uses the same engine for streaming. WebTorrent also powers https://wormhole.app an end-to-end encrypted file sending service that…

I got WebTorrent running on iOS via play.js (Node, rather than Safari, so it supports native sockets etc.). Might be the first non-jailbroken torrent client for iOS :) Very nice project, and works extremely well!

I built Pottery, a C template library. It provides vectors, hash tables, binary search trees, priority queues, sort algorithms, etc.

https://github.com/ludocode/pottery

These templates are composable: high-level templates are implemented using lower-level ones. It also supports custom lifecycle functions, so you can tell containers how to copy, move, destroy your values; it supports custom array access functions, so you can use algorithms like sort or heap over a generalized array that may not be contiguous in memory; and more.

There is still nothing else like it as far as I know. The closest alternative is CTL but it doesn't have any of those features:

As a system administrator, I’m frustrated by two things : * The existing backup tools, that are all hyper-specialized, all configured differently, all have slightly different feature sets, and so on. You will likely have very different tools to backup, say, your /etc folder and your mariadb database * cron is cool, but its logging/alerts capabilities are… subpar, to say the least So I’ve developed tools to alleviate…

Nice, I hear you on the risks of depending on 3rd-party libraries where you can't get your changes merged. It's nice to be able to roll your own in that case.

On the cron case, what are your thoughts on the email notifications? In what ways are the useful or useless? I'm not an expert in this stuff.

And I really like the look of uback. I have the kind of sense (and pride) that maybe this thread I posted is going to be the place where some people (who were maybe previously laboring on something in obscurity) first posted it to the world, or mentioned about it. Or maybe were even encouraged by this Ask post, or seeing other people post work, to post their own work. I'd love it if that were the case, if this post of mine was something that contributed to people posting their work that went on to become something good. :) Not trying to give you pressure, but uback could be that. :) It's pretty fresh

Still in the process but: a software renderer, a cross-platform gfx / audio api, a scripting language, code editor, sprite editor, ... (libs are all written in C for portability and easy scripting integration) Totally meaningless (to others) wheel reinventing, but it makes me 100x happier when making games and apps! DIY everything is my path to programming happiness (in any field in fact). Tools should be extensions…

There is a lot of truth to this. I'm generally good at avoiding this at work but I devolve into "DIY everything" in all of my side projects. It's certainly not the most productive way of producing software but it's the most fulfilling.

I wrote a library for animating image backgrounds on the web using After Effects style filters and transitions: https://aeroheim.github.io/midori/ It's basically a post-processing pipeline implemented with Three.js and WebGL using a few shaders that I wrote. I created it primarily because I needed it for one of my current projects, so the use case is fairly niche and mostly only relevant for stuff like creative codin…

This is shockingly good! I want to use this. Amazing work.

Both Java.

Pyranid - https://www.pyranid.com

I prefer SQL to ORMs and I don't like libraries with dependencies. Really simple mapping of resultsets to Java objects. Plays nicely with DI (I like Guice a lot).

Lokalized - https://www.lokalized.com

Another no-dependencies lib. I don't think any other platform handles translations in a powerful enough way. The magic is a simple expression language that lets the translator specify rules (e.g special cases for certain languages to be more "natural sounding") instead of embedding all that logic in code.

In 2016 I was unsatisfied with the QR Code generator libraries available in the wild, especially for C, C++, and JavaScript. Hence I wrote my own: https://www.nayuki.io/page/qr-code-generator-library ; https://github.com/nayuki/QR-Code-generator

I also made some visualizations into the internals of QR Codes: https://www.nayuki.io/page/creating-a-qr-code-step-by-step ; https://www.nayuki.io/page/optimal-text-segmentation-for-qr-...
