I'm implementing Raft consensus from scratch in C++ with raw TCP sockets. Right now I'm working on a high-performance RPC client and server to keep network latency to a minimum. The main purpose of this project is to hone my systems programming skills and get more comfortable with distributed systems as well. One of the coolest things I've learned here is event-driven I/O with epoll and how event-loop architectures w…

#764The main difference between my app and anki/other generic flashcard apps is that it is for vocabulary only, which allows me to add features specific for language learning.
For example, you can set it up such that each word shows up with a different sentence and image each time you see it.

#765The last couple years I've been prototyping a not-for-profit pinball museum in Chicago. In the coming weeks we'll be opening 7 days a week in a 2900 sq ft space in the Loop: https://theflip.museum/ It's my first time starting a physical, retail business and it has been quite an education in the small details.
We enjoy going to a similar pinball museum here in Pawtucket, RI, which you might be familiar with:

#767European night trains search engine. The plan is not to provide the functionality where user searches for a specific route on a specific date and the engine returns prices. The plan is to provide "tips for trips", e.g. I provide a starting city and it will recommend me interesting trip ideas any time in the future. There are many flight apps that provide this functionality, but no train app. Currently I'm building sc…
This case perhaps merits a hard-wired message "for this trip, we recommend a day train, or we'd regret you'd miss the panoramic views".

#768We're working on Drawers ( https://drawers.computer ), a macOS app to give each of your projects its own dock, space, and windows. We integrate with macOS spaces to switch out a project-specific dock on each space, containing only the resources you need for that project. We made it possible to add granular resources instead of full apps to the dock (think specific slack channels instead of the whole slack app), to ke…
What I'd suggest is that you isolate the project spaces from one another so that a e.g. a Web browser crash caused by one project space cannot drag down the rest. BTW, I'd pay for this!
Keep building.

#769[clue.ssh](https://github.com/aspectrr/clue.ssh) A clue game over SSH based on the AI wave, where the goal is to find who stole the H100. Pretty fun and coding agents can play too.
[Chasing Losses](https://github.com/aspectrr/chasing_losses) I was interested in if LLMs chased losses when playing roulette, still investigating this but i've found that different models will bet different amounts at different frequencies even when prompted the same. Struggling on not wanting to guide them too much but also wanting to see how they react when put under pressure.

#770I'm constantly working on https://only-eu.eu/en A directory of European software and general alternatives to popular products. Think cloud storage, email, VPN, browsers, smartphones, bikes,... About 175 products across 30+ categories right now. Next categories will be: personal health, commercial e-mail and newsletter management. If you have a product that's missing here, please feel free to suggest it via the sugges…
For what it's worth, two days ago on the radio some politician said that for more software sovereignty to take off, all we'd need is such a catalog! ;-).
