Building an electric 1973 Ferrari Dino to compete in the battle of the builders at SEMA in November. Lots of fun electronics and software, as well as mechanical challenges to overcome.

sounds interesting - any pics/project site?

Late to the party - I'm building a "remote" for https://github.com/babybuddy for my future child. It's based around an esp32-s3 and has: - 10 switches that I can assign to start/stop timers and trigger events (Kalih Choc Robin) - One encoder + four way directional switch - Round LCD display with touch - 9 DoF IMU and ambient light sensor

If we won't use it for our child, I'll use it as a slightly overpowered macro keyboard :D

Of course I intend to publish it as soon as I have the first prototypes debugged!

I'm working on a new product, Datagram, which makes it easy for developers to share metrics using an API and mobile app. I've found that it's difficult to distribute metrics inside an organization. Today, most teams rely on systems like PowerBI / Tableau which are great for deep analysis, but can be too complex for sharing headline data to a large audience. Or, even more challenging, data can be locked in spreadsheet…

i would love a drop in self hosted replacement for datadog that looks good.

Curious if https://github.com/hyperdxio/hyperdx passes the bar for looking good!

(disclaimer: I'm a maintainer that's done a good chunk of the UI - but I also love candid feedback)

Org-mode grammar (PEG parsing) for GNU Guile. Still at the very beginning, but hoping, that over time I can add more and more things, to make it a useful library for things like a minimal static blog based on org mode files or if any git hoster wants to have a good parser for org mode files to render readmes ... That, and my personal website, using only HTML and CSS, and trying to keep it minimalistic, yet nice looki…

An org-mode grammar for tree-sitter exists already. Why not use this instead of making your own? Tree-sitter however is LR parsing, not PEG, is it not powerful enough?

I'm working on Learntime (https://learntime.ai), an open-source/saas learning app that combines AI mentorship with evidence-based study techniques. It's designed for students and lifelong learners who want to retain information more effectively and perform better in exams. It focuses on un-prompted recall of entire topics (not just flashcards), supported by an AI mentor that provides hints and tracks progress. It uses spaced repetition to optimise review schedules and includes a quick quiz feature targeting weak areas. This is my first solo open-source project, and it's been quite a journey! I initially started with LangChain, thinking it would simplify the AI integration. However, I found myself spending more time wrestling with abstractions than solving core problems. Eventually, I dropped it in favour of a more direct approach. The biggest technical challenge has been implementing free recall scoring with LLMs. I've been through a cycle of different techniques - prompt engineering, few-shot learning, fine-tuning - and back again! All of this while welcoming my third child and approaching 50! It's been a balancing act, but the project keeps me energised. Feedback, similar experiences or insights welcome!

I built an English-speaking website that helps immigrants settle in Berlin.[0] It has been my full time job for a while. Most English speakers know about it, but it's nearly invisible to Germans, who would also benefit from the content and tools I have worked on. I'm currently adding an automated AI translation feature to my custom static site generator, so that I can translate the website to multiple languages and r…

Very cool. I would love to see a writeup of your translation workflow eventually.

How long have you been working on this site?

Hey guys! We're engineers/designers from France, and we've built the Ultimate DIY Battery that you can repair and refill! - Ride Sustainably with the World's First Repairable Battery - Refillable in 5 minutes (just buy $150 worth of new cells every 3 years or so, when they're depleted) - Be Worry-Free thanks to the Fireproof Casing! There's been waaaaaay too many lithium fires! It's launching as an IndieGogo in one w…

Is hardware open source? I would love to go through schematics to see how it works.

I was excited about the Cloudflare announcements this past week. I primarily use AWS in my day job, but I wanted to broaden my knowledge. This weekend, I started building a simple to-do application using Durable Objects and the newly announced zero-latency SQLite storage. In just a few hours, I familiarized myself with Cloudflare and got the basic CRUD operations working. Next weekend, I plan to add WebSocket publica…

This is really cool, I wasn’t even aware Cloud flare is working on these kinds of things. Thanks For the news
