I developed a quadcopter with a custom flight controller, programmed in Python (@micropython), that can efficiently run on a $4 @Raspberry_Pi Pico microcontroller! Check it out: github.com/TimHanewich/Ce…

@KentonVarda Beautifully said.

I just declared a moratorium against AI-written change descriptions (e.g. PR and commit messages, also issues/tickets) from my team. AI was writing change descriptions that were worse than useless to me as I tried to review PRs: outlining details of the code that could easily be seen by looking at the code, but omitting the higher-level framing needed to understand broadly what the code is doing. I think people like having AI write these things because the output looks structured and thorough, which makes it feel professional in a way. But this isn't actually valuable. Concise, high-level descriptions are better for everyone. If I need to use my own AI to interpret what your AI wrote then something is wrong. Let AI write code, sure, but for the description, I'd rather see your prompt than your output. We could maybe have extended agents.md with guidelines on writing descriptions, but this seemed a bit pointless since a good, concise change description only takes a few minutes to write -- not a significant time savings to delegate to AI. At least, it doesn't take long if you understand the code -- and if you don't understand the code, then I'm definitely not merging it.

@margaretmelonii Optical flow sensors on the bottom observe objects below it and keep it fixed relative to those

Sem ironia, como o drone não está preso a nada, ele teria que voar na mesma velocidade do carro para ficar estável assim?

@_bschmidtchen Very cool well done

We're adding some new default worlds to our preview demo, check it out at reactor.inc Make sure to prompt your own world as well, anything you imagine is possible.

@ryanbrewer Agree and feeling this as well. The value/importance of "understanding" feels like it is going away. I wrote an article about it. yes, I wrote it... No slop :) timhanewich.medium.com/the-understand…

My entire job is now codex and managing codex threads, I’m genuinely curious what the software engineering job even is anymore. The value of my understanding of any system goes down every single day. Very weird times

@mom_agency_ More of this please!!!

Claude's first day at Dunder Mifflin

I just published "The Understanding Gap" AI lets us produce far beyond what we understand. As we use agents more and more, the real skill becomes knowing: - What to understand - How deeply to understand - When NOT to outsource your thinking Read more: timhanewich.medium.com/the-understand…

GitHub Copilot's rates are rising, and Claude Code’s session limits are now expiring too quickly often within 30 minutes. What are some viable alternatives we should look into?

@rvm0n_ @icanvardar That's not c# that's D flat

@icanvardar what kinda question is this?

who is still using c# in 2026?

@billcompute Installing open claw is the last decision you will have to make. After installing you can defer all decisions to open claw. Gives you more time to talk with your wife, Qwen.

“Mom, how did we get so poor?” “Your dad said Openclaw is a fad and refused to buy 31 Mac Minis.”

@billcompute Qwen Stefani 27B or 35B? Not that weight matters, just more to love.

I just fired ALL my employees and replaced them with OpenClaws! Bold? Stupid? Genius? As I was laying in bed last night me and my wife had a heart to heart. 5 year plan. 10 year plan. That sort of chat. I broke down. I couldn’t take it anymore. “I’m gonna take my life back. I pay thousands of $$$ per month for people I must babysit.” I said, wiping the tears running down my face. “I’m gonna fire all my employees.” My wife gasped. I could feel the tension building. “But Bill…” she started. “You don’t have employees. You need to get a job. I can’t take it anymore.” This is why I don’t discuss business at home. Some people just aren’t built for entrepreneurship. Oh and my wife’s name? Qwen Stefani.

Good flying today 😊

Blast off

Successful day today! The ferrite beads + capacitors certainly seemed to have helped, but not as much as I had hoped. Much more stable Rx now, but still rocky at certain moments. Just one of the flights from today. Enjoy! github.com/TimHanewich/ce…

Let's fly! 🤞

From 8-bit to 16-bit checksum. This will vastly lower chances of accident caused by random pass. github.com/TimHanewich/ce…

Installing ferrite beads and two capacitors on the HC-12's VCC and GND lines seems to have significantly reduced the noise emitting from the SMA port + antenna caused by EMI from the ESC's. github.com/TimHanewich/ce…

We're back.

Circuits restored

@tt12514 Changes I'm making: 1. 2-byte checksum used now (reduces likelihood of random pass from 0.4% to 0.0015%) 2. Rx buffer dumping logic in case of overflow due to bad data 3. Ferrite beads & capacitors places on VCC + GND to HC-12.

@tt12514 Thanks for thoughts @tt12514 Yes, the range of the "mobile" one was still ~100 meters. But that was w/ spring antenna and holding about head height, within Fresnel zone. I documented my theory on how this happened here: github.com/TimHanewich/ce…

Today's work: repair burnout damage This was caused in a high-load test I ran a couple weeks back. Too much current I guess! 🫣
