My #cyberdeck build is almost done. #3dprint is complete, parts are assembled but not painted yet. Still working on the #rust TUI application that runs on the main screen. #freeCAD

I made a website to control the content on my retro cube. If you’d like, send me a message :) retro-cube.jflessau.com/form user: retro password: cube #3dprinting #pi #rust

I made a housing for a #pi zero, an #OLED, and a dial for navigating between the views: - Date & Time - Weather - A message fetched from a server The server hosts a web form to update the message. I think the colors turned out pretty cool :) All written in #Rust and designed with #FreeCAD.

Switched from #blender to #FreeCAD for my #cyberdeck build and finally gathered all the hardware parts. #3dprinting it tomorrow! Still not sure how I’ll paint it, though.

A small part of me wishes people who start hitting the gym in January would give up sooner. This year most stayed until March and it was so crowded.

Had some fun with fuel price data from the german cartel office and wrote about it. Teaser: Very synchronized prices of two gas stations, different companies, 5 km apart, no clear line of sight. [one frame = one station] #data #datascience #blog #opendata jflessau.com/projects/gas...

A friend and I built mcsprit.de, a website to see real-time gasoline prices in Germany. Prices change so often that you’ll likely see a different one by the time you actually arrive. That’s why we’ll have some fun with time series prediction models. #civictech #solidjs #rust #ml #datascience

First 3d print for my #cyberdeck project turned out so well. Measurement for all the parts were correct 🤯 But I forgot some parts 🙄 Anyway, super happy with the look and feel. #raspberry #pi #3dprint

Recently discovered the subreddit r/cyberdeck, and it's the coolest thing ever! I'm now building one with two OLED displays, a 3×3 keypad, a dial, etc. Can't wait for the first one to come out of the 3D printer. The UI will be built with ratatui. #cyberdeck #blender #3dprinting #rustlang #ratatui

Before LLMs, I was using spellchecking tools to get errors out of my english texts. After LLMs, I’m putting some back in so no one knows I’m using them. #llm #ai

Wrote a CLI for formatting SQL within sqlx macros like query_as! It includes a GitHub CI Action for format checks and uses the sqruff formatter under the hood. github.com/jflessau/sql... #rust #sql #postgres #ci #github

Switched from cargo test to nextest and its output is much nicer. It's also a few seconds faster on a 2-3 minute set of integration tests. nexte.st #rust #tdd

Just wrote a pice about that time I built a bot to win giveaways on twitter, circa 2015. (It actually worked) #dev #python #bot #blog jflessau.com/projects/ret...

GPUI (v0.2.0), the GPU-accelerated Rust UI framework that powers Zed, is on crates dot io. 👀 crates.io/crates/gpui

Made the switch from #hugo to #zola as the static site generator for my personal #blog: jflessau.com It doesn’t really matter much to readers, but I needed a justification to spend a few hours on a new design.

You can use #vim keybindings in #obsidian.

Wrote a piece on coding with AI. Bottom line: Autocomplete is fine; agentic editing is overhyped, at least for now. Autocomplete lets you code at the speed of thought, while agentic editing breaks that speed limit, and you have to catch up mentally anyway. #ai #blog jflessau.com/dev/ai-coding/

I can see myself making this mistake at some point. #dev #bash qouteall.github.io/qouteall-blo...

Rooting for this little fella to escape from my monitor before dying. Any tips?

Used a text-to-image model, then an image-to-3d model. Cleaned, rigged, and painted it in Blender. Feeling a bit conflicted, but I see no other way to make my game happen alongside a full-time job without AI. Thoughts? #gamedev #ai #bevy

Using #bevy and #blender to create my first 3D video game. #gamedev

That was surprisingly hard, but here we go. Kubernetes on the Apple Watch!

A few months ago, my application with the Fuel Registry of the German Federal Cartel Office was approved. With access to the gasoline and diesel prices they provide for all of Germany, I'm now building a small web app. #webdev #CivicTech #buildinpublic

A 3D printable frame for an e-ink display and a public website to control its content. I'll let the internet decide what I see next. What could go wrong? Control the frame here: inkday.jflessau.com Or set up your own: github.com/jflessau/ink... #3dprint #diy #webdev

Google: Material 3 Expressive is the most researched update to Google’s design system, ever. HN:

Trying out agentic editing in the #Zed editor. It's mesmerizing to watch it create and edit files 🌀 Building a PWA to track expenses collaboratively. For this little side project, it's working surprisingly well. #webdev #solidjs #buildinpublic

Made this 3D printable base for #dnd minis that projects a field of view cone with an adjustable angle. STL files and some more pictures are available here: jflessau.com/projects/bea... #3dprint #3d #rpg

Built a thing that creates 1-2 minute audio digests from hashtag posts. What do you think? #buildinpublic Includes posts from: jkemppainen.com - vehicle combat game monfang.bsky.social - outreach strategy chromatic-ai.bsky.social - PRAY app revenue indieceo.bsky.social - open-source licensing

Tried a drag-and-drop workflow tool and built an #automation that grabs the top X #HackerNews stories with their top Y comments. It uses AI to summarize and convert them into a 1-3 minute audio digest sent to my inbox twice a day. Loving it!

Just rediscovered my Pixabay account and saw that my vector graphics have been downloaded 5 million times! 🎉 Reverse image search showed that they're all over the internet. Made my day! :)

Working on my first #solidJS project. I chose SolidUI to build a nice frontend, and it is amazing. It looks great, and the developer experience is neat. #webdev

Wanted a #postgres fan shirt, so I made this using #ai and #affinityphoto. Printed shirt will arrive in a few days.

My take on a habit tracker web app: - 👤 No login required - 🔌 Works offline - 📁 Import & export data - 📄 MIT licensed Built with #rust and #leptos. Demo: ritmo.jflessau.com Repo: github.com/jflessau/ritmo #webdev #buildInpublic #rustlang

Hardly new info, but BSky should know: Warsaw's water quality is monitored by eight clams with magnets attached to their shells. If contamination in the water causes the clams to close, the magnets trigger an alarm and shut off the city's water supply. Thank you, little guardian molluscs. 🧪🌏🚰

Where are you renting cheap GPU instances for a few hours or days? I tried: Paperspace: Borderline unusable since Digital Ocean bought it. Lambda: Cool, but the availability of cheap instances is volatile. RunPod: My current go-to. Prices are okay, as is availability. How about you? #ml #ai

Finally, Kubernetes in space!

Populated a table with 1 million rows in both #Postgres and #SurrealDB and ran queries. Postgres is significantly faster.

I'm building a Postgres desktop GUI in Rust using the gpui crate (the framework used to create the Zed editor). These are the humble beginnings, and I'm having the time of my life with this project :) #postgres #rustlang #zed

This post I wrote on Postgres transaction isolation is still my go-to cheat sheet. If you need to check what isolation level to use for xyz, it might help you too :) jflessau.com/dev/postgres... #postgres

I’ve created a web app that detects voice activity and inserts canned laughter in between. I call it Sitcom as a Service. Check out the demo: canned-laughter.jflessau.com Hint: doesn’t work in Safari #webdev #svelte #rust #rustlang

I created a web app for chatting with people on the same public transport vehicle. It automatically connects users with similar location, speed, and direction of travel. No login required. Repo: github.com/jflessau/cat... Demo: catenary.jflessau.com #rust #leptos #webdev

Created this in #blender to generate 3D-printable drawer inserts for organizing items. If you’d like to generate some for yourself, you can do so with just a few clicks: github.com/jflessau/dra... #3dprinting #blender3d

Made a multiplayer BS bingo game using #rust and #svelte. Game: bingo.jflessau.com Repo: github.com/jflessau/bs-...
