Show HN: Low-cost backup to S3 Glacier Deep Archive
Hi,<p>most people (hopefully) have local backups. However, when that backup fails, it is good to have a backup stored somewhere off-site. In the old days you would ship physical drives/tapes, which is cumbersome, costly, and slow. With fast upload speeds, it is now possible to upload your data to the cloud. I have found S3 Glacier Deep Archive to be a great solution for this:<p>- It is very cheap ($1/TB/month for US region)
- Very reliable (99.999999999% data durability, data spread over 3 Availability Zones)<p>However, usability out of the box is not that great, I'm not aware of any automated backup solution for Deep Archive. This free project provides that.<p>Currently, ZFS is required, but that might change. Please try it out and provide feedback!

Show HN: StackAid – Fund all your open-source dependencies
We strongly believe working on open source software should be a viable source of income for many more developers. Unfortunately, the following barriers limit the extent of open source funding:<p>- Only a small fraction of open source projects are funded, and most money goes to a few notable projects.<p>- Each project has to market is self to get significant funding.<p>- Large corporate donations provide the bulk of the funding, making it unreliable and unattainable for many.<p>- Finding and supporting each of your dependencies is a cumbersome task. Which ones, how much, and on which platforms?<p>So we built StackAid, a service that automatically discovers and funds your direct and indirect (second order) open source dependencies with a monthly subscription. StackAid is early and has a unique allocation model, so we're working with supporters and open source projects to validate the experience further. We're matching subscriptions up to $100/month during the beta.

Show HN: Mini Metroidvania in 13KB of JavaScript
As part of the annual JS13K games challenge, I've put together a pretty large (but small-in-code) Metroidvania game that fits in just 13KB of compressed Javascript.<p>The source is available here: <a href="https://github.com/arikwex/infernal-sigil" rel="nofollow">https://github.com/arikwex/infernal-sigil</a><p>NOTE: the current head of the main branch is at 13.6KB due to quality of life patches. The legit 13KB version is tagged in github.<p>Useful hacks:
- Using Roadroller (<a href="https://github.com/lifthrasiir/roadroller" rel="nofollow">https://github.com/lifthrasiir/roadroller</a>) for compression
- Compressing the map data as grayscale PNG paired with some code generation.
- Using procedural animation for all characters.
- Replacing string enum with numeric enums for compression.
- Built a small game engine for object lifecycle and rendering.
- Single function to generate unique procedural songs for different regions.

Show HN: I made a modern web UI for Hacker News
Hey HN,<p>I made this free browser extension that modernizes the Hacker News design.<p>I previously launched Modern for Wikipedia [1] here back in December, and it seemed like the obvious next choice to build one for HN too! So I've taken what I learned from building that, and have spent all my spare time this year building Modern for HN.<p>I realize this won't be for everyone, but it was a fun project to work on, and I'm really happy with the result so far. Hope you like it too!<p>Lots more planned for future updates, and suggestions welcome :)<p>[1] <a href="https://news.ycombinator.com/item?id=29461735" rel="nofollow">https://news.ycombinator.com/item?id=29461735</a>
Show HN: Quake 1 ported to the Apple Watch
I ported Quake 1 to the Apple Watch, building on top of existing ports for iOS and Mac.<p>Some features:
* uses Quake SW renderer + blitting to WatchKit surface (~60 fps, 640x480, larger res can run on lower framerate, tested up until 1024x768)
* touch + gyro + digital crown controls
* new AVFoundation audio backend (quake to Watchkit audio buffer copy logic), as Watchkit does not support CoreAudio
* high pass audio filter to remove clicking on Watch speaker for some of the low frequency quake .wav samples
* some smaller modifications and code updates to glue Quake 1 c code to Objective C and Watchkit<p><a href="https://www.youtube.com/watch?v=cPC2o262TfQ" rel="nofollow">https://www.youtube.com/watch?v=cPC2o262TfQ</a>

Show HN: Make 3D art in your browser using Lisp and math
Bauble is a toy that I've been working on for a few weeks, and I think it's reached the point where other people could have fun with it!<p>Bauble is based on raymarching signed distance functions, which are kind of like... 3D vector art? They're pretty common in the procedural art community and you can do some amazing things with them, but normally writing SDFs means writing low-level shader code.<p>I wanted to play with SDFs, but I found it very frustrating to translate "I want to rotate this" into "okay, that means I have to construct a rotation matrix, and then apply it to the current point, and <i>then</i> evaluate the shape...". So I made a high-level Janet DSL that compiles down to GLSL shader code so I could more easily play with mathematically defined shapes.<p>For more about SDFs, this mind-blowing video is what got me interested in the first place, and shows you what they're capable of in the hands of an expert: <a href="https://www.youtube.com/watch?v=8--5LwHRhjk" rel="nofollow">https://www.youtube.com/watch?v=8--5LwHRhjk</a>

Show HN: Wavvy – web-based audio editor (Audacity port)
I originally developed a WASM port of wxWidgets for <a href="https://dj.app/" rel="nofollow">https://dj.app/</a>. When it came time to open source wxWidgets-wasm, I decided to port another complex app as a test case, and Audacity seemed like the obvious choice. In the process, I also needed to write a new host API for PortAudio for playback and recording in the browser.<p><a href="https://github.com/ahilss/wxWidgets-wasm" rel="nofollow">https://github.com/ahilss/wxWidgets-wasm</a><p><a href="https://github.com/ahilss/portaudio-wasm" rel="nofollow">https://github.com/ahilss/portaudio-wasm</a><p><a href="https://github.com/ahilss/wavvy" rel="nofollow">https://github.com/ahilss/wavvy</a>
