I spent a few hours building the smallest kernel that'd boot in Firecracker ( https://blog.davidv.dev/minimizing-linux-boot-times.html ), got it booting in 6ms with network support, which opens up some interesting use-

The constraints fuel creativity, but it also pushed me to start writing a Lua compiler for PicoPico, which shows promise but is also a massive scope creep and mostly the reason I've not worked on PicoPico for a while

With Lua's design, each bytecode operation requires a bunch of memory accesses, these microcontrollers only have a limited amount (~500KB) of SRAM, so you need to place this memory on PSRAM (RAM over SPI) which has "significant&qu

Hey! I feel like I would be a good fit but unfortunately did not pass the CV filter a few months ago, send me an email if you are interested in chatting.

libfaketime's awkward interface (control via timestamp files, needing LD_PRELOAD) is why I wrote an experimental library[0] which takes over the clock at the process level. My library modifies the code for the time-related vDSO functio

Why not use something like shiv[0]? You can bundle all your dependencies into one file and distribute that. [0] https://pypi.org/project/shiv/

I bought a bunch of the 16Mbit flash variant for an embedded project but sadly it looks like the firmware always gets corrupted on write, and have gotten no reply from Bouffalo https://github.com/bouffalolab/bouffalo_sd

I'm not sure I understand, everyone is allowed to apply. The position requires relocating to Amsterdam. If you think something went wrong, shoot me an email (profile) and I'll get it reviewed

It looks cool, though I still find myself looking for Hyperlapse[0] alternatives. Hyperlapse seemed like magic when announced, particularly, not needing to crop large parts of shaky videos [0] https://blogs.microsoft.com/ai&

I have a gen12 i5. The thing I am dissappointed with is battery life. Will a motherboard swap to AMD significantly improve on this?

Try out shiv[1], it will package up your source and depndencies into a single file, though you still require the Python interpreter to run it on the target [1] https://github.com/linkedin/shiv

I'm a bit sour reading this. I've always liked fly and particularly the engineering blog, so much so that a couple of months ago I decided to apply for an infra position, to work on some of these very topics. Sadly after 4~5 round

The easiest way to do this is to use shiv[0] if you don't mind asking people to have Python itself installed; if you want a truly "one file bundle" you should use PyInstaller[1] (which bundles a Python interpreter) [0]: http

Sure! Feel free to message me in github or via email. I've abandoned my Pico8 on RP2040 port though, a lot of games simply need more memory than there's available. There's this crazy guy: https://github.com/yo
