The simulator can execute now LOIs (Lunar Orbit Insertions), and also Free-Return Trajectories - that saved the life of Apollo 13. Every single dot that you see, is actually *calculated* by an orbital mechanics physics engine.
Having some fun with orbital mechanics, and TLIs (trans lunar injections)... 😁
Over the last 6-8 hours (spread across 3 days), I’ve vibe-coded a Home Assistant dashboard that displays data from our photovoltaic system, collected via Modbus over the local TCP/IP network. Home Assistent runs on my old Odriod-H2 Mini-PC from the year 2018...
Working with multiple sub-agents across multiple GitHub issues in parallel - works like a charm :-)
I have now a full-blown working UEFI boot path in my OS - incl. a simple AHCI driver to access the SATA based SSD drive with its FAT32 ESP partition. 100% pure Rust code (not a single asm file!), without any dependencies to other crates! #rust #rustlang #x64 #computerscience
How to escape the heat wave? Starting a 100K “red eye” bike ride at 05:00am in the morning… 😴😴😴
It's the 1st time in my life that I've implemented my own UEFI loader - entirely in Rust - without any external dependencies. #Rust #rustlang #computerscience
I have migrated now my whole x64-based OS entirely to Rust. There is NO single line of C code anymore - just a few pure assembly files! In addition, I'm also providing a VScode based Dev-Container, with which you can even build and run the OS in your browser! #rust #rustlang #osdev #computerscience
Finished the first bicycle race of my life: the „Dolomitenradrundfahrt“ in East-Tyrol. 110km with 1700m ascent! 🥵 4:19h, and the 96th place (out of 153 participants) within my age group! 💪
What a day: finished my 1st Aqua Bike competition. 53th out-of-water (the last one!), and finished after the bike split at the 26th place - in 3:48h! 💪
CoPilot in SSMS reads from my database/sql server instance, but doesn't show me any executed queries. This is *so* dangerous for your production data - CoPilot could just pass some of your sensitive data to the LLM provider... #ai #llm #datasecurity #gdpr
I have never thought that software engineers will be substituted by endless loops... #AgenticAI
Using various LLMs to design and implement a web app. The results are amazing.
Working in VScode with the @continue.dev extension against the model "meta-llama-3.1-8b-instruct" that runs locally in LM Studio on my MacBook Air (M3, with 24 GB unified memory).
Während ich mich im Orkan durch Graz gekämpft habe, hat Philip seinen höchsten Gewinn seines Lebens eingefahren: ein Sieg (4:30h Spielzeit) gegen einen ELO 2150 Gegner! 💪 Nach 90min Pause geht es um 16:00 gegen einen Fide-Meister aus Ungarn weiter… 🤗 #chess
Neo has a meeting at the #Oracle. Let's see if he takes the red or blue pill..
I have now a fully working preemptive scheduler in my OS available. Spawned tasks can already put into sleep when they wait on external resources (currently key presses from the keyboard). Everything is written entirely in #Rust - besides the necessary bootsector stuff.
