cache crab

i am proud to announce that i am now a founding engineer @helixdb

@xzcendence you only need to support the board you use and when it comes to aerospace ethernet you can’t use off the shelf anyways

@cachecrab cool in theory but the ecosystem ain't the same. zephyr networking stack and board support is insane

embedded rust is incredible

@xzcendence nope. rtic.rs

@cachecrab zephyr mogs unfortunately

@DjMolehill not even sram, TCM

@cachecrab zero cost abstractions actually matter when you're fightin for every byte of sram

every task using the same stack, safe preemptivity by specifying what locals are needed. fully automated critical sections

you don't need an RTOS. you can get hardware-accelerated (zero-cost) hard real time with macros and Stack Resource Policy

@pizzaboy it's gonna happen

@cachecrab yeah wouldn't that be sick

New site is live along with a new Request For Clients page (similar to what YC do pre-batch!) Theres also an easter egg on the new site that no one will find. happypizza.studio/request-for-cl…

@Great_Chumpion long and thin move fast short and fat move slow

No but seriously why does the *short* hand tell the larger unit of time, the hour. This thing was always so counterintuitive the whole time that I get why with modern clocks, it's fading away.

@Deor this is the exact opposite of what people say its opus that understands vibes better. if you're serious then gpt-5.5 is the better skilled worker

if you are getting better results with gpt-5.5 than with opus 4.7 the problem might be your prompting

@giffmana i bet @archildata handles appends atomically

Whew, I've been programming in C/C++ and Python for over 10 years each consecutively, totalling over 20 years, and only today I learned that the below two are NOT the same, and it's even worse. In the "normal" mode when you seek to EOF and write, that's not atomic (obviously). Append mode atomically seeks to EOF right before any write. So the diff exists most noticeably in parallel-writer scenarios, where append mode is the one you want; in single-writer it's only saving one syscall. HOWEVER... It's actually up to the file-system to implement this correctly, and... It's explicitly NOT true for NFS, where append-mode writes are NOT atomic afterall. So really, you cannot actually trust append-mode unless you know for sure all of your users are not using this on NFS.

@yacineMTB you actually get the transcript of this and feed it in to codex youtube.com/watch?v=vYA0f6…

You don't. You can just vibecode your own CUDA accelerated aerodynamics simulator using some old SIGGRAPH paper as reference

@bruvimtired @aaronmahlke pause

@aaronmahlke i can show you where to place it when i visit you

an insane domain pull

HelixEXAGON

5.6 will not have a nerdy personality confirmed?

@ludwigABAP insane

my new flight is also borked so I’m now flying to Chicago to transfer to SF, incredible stuff 🙏

@monty10x happy birthday!!
