⚔️ Firmware flame war starter:

“Rust is too heavy for MCUs.”
“C is unsafe.”
“Tooling matters more.”
“Memory footprint decides everything.”

Meanwhile, here’s data from an industrial comparison of Embedded Rust vs C using Ariel OS https://t.co/0BoNFAg12Y

The article titled "Fully Preserving Fisher-Price Pixter" is a fantastic @dmitrygr job!

Extract of the TLDR by himself: […] complete reverse engineering, documentation, emulation, and preservation of all […] device series and [almost] all the games

linux networking is so low level that you can sniff every packet your machine sees with a single raw socket.

without wireshark and libpcap the kernel handing ethernet frames directly to userland.
linux literally exposes raw layer-2 traffic to userspace.

Do you remember the PC Engine? The TurboGrafx-16 in the US? I used to love this video game console so much. How was its hardware?

Fascinating thread @jwt0625 😍

[outside five sigma @jwt0625]

should've bought some photonics stocks when I first saw this video.. anyway this is a photonic integrated circuit chip from a 1.6T DWDM transceiver module by Infinera (2 wavelengths x 2 polarizations (DP-64QAM) x 96 GBaud), and I'll make some guess on what is going on on this PIC.

before I start, you can zoom in onto the edges and see the facets were cleaved... (the year was already ~2020)

When 'Close to the Hardware' isn't close enough

A great reminder that the real “Hello World” of embedded systems isn’t blinking an LED. It’s understanding everything that happens before main() even exists https://t.co/BxHpqHBqd8 #embedded #embedsys
