#412Not completed yet, but I am working on Stocklist (https://stocklist.live).
One can create, share and follow collection of stocks from all over the world.

#413https://github.com/marenbeam/thoughts
I made a portable shell program for making short text posts from vim.
The code's not perfect, but it does what I want from such a thing, and I'm enjoying using it and seeing others use it too!

#414No surprises from me: I launched v8 of my HTML5 canvas library back in April, which the admins here very kindly promoted to the front page of HN for a couple of hours - https://scrawl-v8.rikweb.org.uk/
Since then I've released some updates to the library. Things I've been working on include:
- Adding a "polyline" entity (which, I hope, can be used for freehand drawing) and fixing the path animation code so things can be moved along a path at constant speed - https://codepen.io/kaliedarik/pen/MWadEwm
- Tweaking and improving the "phrase" entity (for graphical text) to make it easier to add styling markup to it, plus some stuff to make it look better when animating along a path ... though sadly there's still an (very!) annoying text height bug that needs to be addressed - https://codepen.io/kaliedarik/pen/dyYeOZb
And for the past few weeks I've been investigating/learning about physics engines. Because what's not to love about physics engines? I'm not close to releasing code for this yet, but I did manage to get the library to play nicely with Matter.js as part of my learning experience (the polylines add a nice touch to the net, I think) - https://codepen.io/kaliedarik/pen/zYvbwBy

#415Do incomplete projects count?
I wrote 1/3 of a novel called "Distanced" - you can read it at https://1drv.ms/w/s!AhRJSX2EIeTqmohIQPPIaNr6TXMnnw?e=rwfXfE.

#416I built a new Optical Flow AI. Instead of being a cranky old man complaining about other people's mistakes, I decided to just fix things myself. Before Corona hit, I had created a new data set and given a talk about all the stuff that current state of the art AIs for Optical Flow get wrong. I find the topic interesting, because those bugs directly lead to drones like Skydio crashing into thin wires or branches withou…
I'm not familiar with Optical Flow research, and I'm sure you already know, but are you familiar with the U^2-Net architecture (a new variation of U-Nets)? I only bother mentioning it at the risk of being redundant because it's new and I know how easy it is to miss stuff in the fire hose that is machine learning research papers. Its results for their specific task, salience mapping, are incredible for such a simple and lightweight architecture. And from a skim of Optical Flow and your example it seems like it might apply there as well. It should be able to grab the long-ranging features necessary for Optical Flow.
Do you have a public dataset that you can share or only a private one? Kinda looks like you built a dataset using Skyrim which ... is brilliant.

#417I built a habit app called SnapHabit [1] that helps you build habits with your friends/family through group habits and through social accountability. I wanted to learn React Native/mobile development while trying to address the fact that for many of us, social distancing and lockdown have isolated us and destroyed our everyday habits. The most interesting thing I've seen is that people really enjoy writing about and…
Good on you for jumping in the deep end to lean React Native and thanks for the advice. I just downloaded your app to take a look at it and it’s really well done. I’m actually going to play around with it for my own personal goals for a bit.

#418Thank you so much for the response to this post. There have been more than 90 products added in the past hour alone. This is incredible!

#419I made a lot of music stuff. I hooked up an Arduino to control music tempo with my heart beat [1], made a browser based sequencer for the Korg NTS-1 [2], and a made a web app to generate patches for Teenage Engineering OP-1/OP-Z [3]

Re: Ask HN: What did you make during lockdown?
#420I have been re-implementing the ninja build system [1] using the ideas from the "Build Systems a la Carte" paper [2]. The software isn't ready for the public yet, but I've written 2 blog posts so far about some of the ideas.
1. Using type-classes to model the expressivity of build systems [3] 2. A Future is a Suspending Scheduler [4]
