Assertables is a Rust crate for smarter assert testing, debugging, and runtime checking. Good news is it just reached 500K downloads so I'm seeking more people to try it in more kinds of use cases.

#242Finally caved and built a custom AI newsletter curation platform for a friend who's been pestering me to automate his GPT news digests. Still no idea if there's real demand, but the learning experience with Cursor and Claude Code has been worth it. After growing my own newsletter to 800 subscribers, I'm convinced aggregation beats adding another newsletter to the pile. Thanks to Claude, it works way better than I sho…
Hey, as the friend who nudged you into this, this really helps me in my work with (former) elite athletes now entrepreneurs/investors and with high-octane executives. These folks receive too many calls, emails, messages, and yes, of course, newsletters and reports. I understood, the last thing they need is another newsletter or report. Instead, they need sharp, AI-driven tools to sift through the noise and surface actionable insights—signals, risks, and next steps, etc. ProCurator AI's platform is shaping up to do exactly that (btw, very easy to set up for users), and it’s cool to see how you leveraged Claude Code and Cursor to make it happen. This whole thing makes it possible for me to deliver these guys customized briefings tailored to their needs and schedule based on the information they receive in their inbox e. g. via newsletters and reports. Curious to hear what others here think about tackling info overload with tools like this.

#243A multiplayer survival game based around voxel physics. Can be described as Astroneer-like setting, Teardown voxel physics, in a Valheim-like online multiplayer survival game. Game isn't really announced yet but I've shown some videos of the tech: https://x.com/Alientrap/status/1909316208563732866 (On Youtube: https://www.youtube.com/watch?v=ZWISaUmvit4 ) https://x.com/Alientrap/status/1918024969939808654
Video demo was awesome, really good stuff! Love seeing how you managed to make gravity actually a thing without simply destroying everything above a certain point, as well as connecting different objects together - I feel like that's something most voxel-based games I've seen have done a terrible job at.
Given the online/multiplayer aspect how difficult has the network portion been?

#244Working on sanctum [0] and reliquary [1]. Soon approaching a 1.0 release for sanctum once I get my brain out of vacation mode and into hacking mode again. A lot has happened this year and I am excited. I will be talking about how sanctum and its cathedrals work at sec-t 2025 [2] so in full swing working on the demos and presentation.

The process names in the sanctum project made me smile :) I wonder why you chose "guardian" and not "bishop" (or even "episcopus"), which is literally "overseer".

#245My roommate and I are still working on Tornyol, our mosquito killing drone! It uses ultrasonic sonar to detect mosquitoes, and missile control theory to ram into mosquitoes and grind them in its propellers. Our target platform is a 40 grams tinywhoop so it’s safe to fly everywhere and makes almost no noise :). A Roomba for mosquitoes! The main plus compared to traditional systems is that a drone can cover an enormous…
I watched your talk, very interesting! Super inventive idea, I hope it works out. Is the name a word play with "torgnole" at all, or does it mean something?
Yeah, you’re spot on! The original name was « mosquitorgnole »

#246Working on fabric construction blocks (like Lego of clothing), that you can use to build clothing and accessories completely by hand without any tools or machines. Intro video: https://www.youtube.com/watch?v=X_eKc6c5tDw
this is simply great! godspeed with the project!

#247I’m currently working on implementing a Minecraft server in Rust. Not a new concept, I know, but it’s a great learning opportunity.
I already have a few basics like loading and saving worlds and placing/breaking blocks implemented.
In a few weeks I will release the first version and host a public server for testing. Then I will also do a show hn.

This is an interesting idea. One thing that might help targeting is to have some sort of chemical that attracts the mosquitoes. In that way you can bring your target to you.
Their velocity is much lower than the one of the drone, so it wouldn’t make much sense to increase efficiency

Any problems with the blades getting dirty?
Not our highest priority concern haha
