I've been working non-stop on my game development tutorial website: https://raizensoft.com/tutorials/ Currently it mainly focuses on libGDX which is my most favorite framework. I prefer code-centric approach because that's how game development should be in my opinion. Most of the tutorials are just pure coding with algorithms explanations. My goal is to build one of the most resourceful website for libGDX because it'…

Great, I will check it out, I am a Java dev and always wanted to learn about game programming!

I’ve been working on an app called Lång. A daily spending guide. It shows you what’s okay to spend based on how much needs to last how long. For over a decade, I’ve thought about how most people seem to resist the advice about money. And also how all advice is based on the same idea: seeing where your money went and making monthly plans based on that. I think people feel that this is a poor match for how money works.…

I've been wanting to build something like this for myself, but partnering/integrating with banks seems to be the main difficulty. How do you solve this?

And which cards / banks does it support?

Also, what does the name mean? It might be a tad difficult to google, unfortunately, since I imagine that googling "lang" would come up with a lot of other results.

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…

Wow... AI told me that all the tested products far exceed the EU limits!

Inspired by a friend getting a random email and it sparking a memory for me: https://pageday.org , a global message lottery where each day a random message is drawn to be the homepage.

What happens if the selected message is unpleasant or against your political views? Do you curate submissions? If so how?

Yeah that's a good question, and something we haven't codified.

Odds are that we'll curate quite heavily to keep it interesting and maybe along similar guidelines to hn with "anything that gratifies one's intellectual curiosity" rather than just "anything".

I'm creating Comper, an infinite canvas that has all your organization's code and documentation on it. If you zoom in, you can see the code, if you zoom out you see the big picture. By giving everything a place on the map, it becomes easier to figure out your way through the landscape and understand the systems. Different modes can you show you different things: code age, authorship (bus-factor, is the person still with the company etc), languages used, security issues. There's time-travel, think Gource for all software in your company, and maybe the most fun: a GeoGuessr for code. Select the repos for your team (or if you feel confident, of the entire org), you get a snippet and have to guess where it is. The plan is for LLMs + tree-sitter to analyze all the code and show relations to other systems, databases etc.

My initial announcement got the top spot in "What are you working on? (February 2025)" https://news.ycombinator.com/item?id=43157056 but now I'm a lot further, there's a website https://comper.io and the company is getting incorporated within two weeks.

Last week I showed it off in the Feeling of Computing Meetup (fka Future of Coding) - the recording is here and the reactions were extremely positive https://www.youtube.com/watch?v=3-rg-FPZJtk

I'm opening the private beta soon, where I mix using the product with consultancy, to get better customer feedback. Not sure if that will work, but I don't have all the features yet for bottom-up adoption.

I got tired of Spotify recommending me the same songs, from the same artists, over and over again.

So I built Riff Radar - it creates playlists from your followed artists' complete discography, and allows you to tailor them in multiple ways. Those playlists are my top listened to. I know, because you can also see your listening statistics (at the mercy of Spotify's API).

The playlists also get updated daily. Think of it as a better version of the daily mixes Spotify creates.

Hi HN, I am working on Circuitscript, a language based on python to describe electronic schematics/circuits: https://circuitscript.net/ Recently, I have released a simple IDE (called the Bench) to try Circuitscript online: https://bench.circuitscript.net/ The next steps are to create more schematics with Circuitscript as examples to test the limitations of the language and to generate PCB designs with KiCAD. The Circ…

As a big openscad fan I love the idea of designing circuits with code.

I do wonder though about designing circuits vs designing schematics. I see you have ‘wire down 100’ making it a more visual language than defining the nets. Be interesting to separate the schematic layout from the nets, so rule base schematic layout can then be applied.

I'm toying around with a language that's like Python but with Hindley-Miller interference and some functional stuff. It's not a superset or anything, because I can't do that, but it's interesting how well HM (plus some well-encapsulated escape hatches) map onto the Python ecosystem with all its dynamism.

Very interesting idea. Good luck!

Working on orbital dynamics code for my PhD in astronomy, written in rust, it can accurately calculate the positions of all asteroids/comets to within a few meters. Today I am adding a new numerical integration method which should enable me to predict orbits from observations.

https://github.com/dahlend/kete

I'm working on modeling the motion of observed dust particles coming off of comet 67P, here is are some example 3d plots:

Example of rocks ejected from one position and their possible motions: https://dahlend.github.io/67p_beta_dust.html

Trying to determine possible orbits from a set of observations (the straight lines): https://dahlend.github.io/67p_dust_orbit.html

Shout out to pyvista for making these great 3d plots possible, a little less ergonomic than matplotlib, but it can export directly to html.
