Happily running the MC1 #FPGA computer @ 120 MHz, after patching my broken DE0-CV board with a new oscillator via GPIO pins (off screen, wires to the right). https://t.co/BfExWMPWSB #MRISC32 #CPU #VHDL #opensource

This weekend's hack: How long does it take to brute force a cryptographic key? https://t.co/GCk0swNBjw

Why not change the Unix epoch to the big bang? The number of seconds since the big bang fits comfortably in an unsigned 64-bit integer (only 59 bits are required, so far). Caveat: All we have to do is to define the age of the universe with sub-second accuracy. 🤔

So far I like https://t.co/tACZ49mr8N - Free European Git hosting, with a familiar interface. #git #codeberg #foss

A very lengthy read about the state of memory safety in C/C++, but also very balanced and interesting, by John Viega: #c #cplusplus #rust #memorysafety https://t.co/tc5lwaEoqQ

One of the arguments against immediate mode UI is that it will drain your battery. I think that's bollocks! Here is my "proof of life" test to measure power draw. Preliminary result is that Dear ImGui consumes less power than YouTube. That feels like a fairbar to compare against

Fun fact: Even when compiled for MRISC32 and running in my (quite slow) CPU simulator, lsb2s is *STILL* faster at generating source code than xxd -include (running natively).

In anticipation of the C23 standard #embed, I couldn't help revisiting the age old covert-binary-data-to-source-code problem. I came up with a ludicrous speed conversion tool (2 GB/s binary data conversion rate). Light speed is too slow! Check it out!

I am making the mistake of responding to this in earnest and, as a disclaimer, Twitter communication is hard, and it's easy to misread things. I assume the tweet is lighthearted, and I appreciate that. Nevertheless, in case it's sincere, I want to address it sincerely: Like most

BuildCache just gained support for caching Rust builds 🥳 Contribution by Firefox developer @__farre__ 🙏 Get v0.29 and speed up your Rust builds: https://t.co/cjF8TEr1WP #rustlang @mozilla @firefox

@romero (BTW, it runs Quake too) https://t.co/aot7zFZpCx

Want to run #DOOM. Need something to run it on. ✔️ Develop new CPU ISA. ✔️ Write new GCC backend. ✔️ Implement CPU and VGA gfx in FPGA. ✔️ Write a minimal OS. ✔️ Port DOOM to the new CPU & platform. ✔️ Optimize rendering code. Now I can run DOOM 🤘 @romero #MRISC32 #FPGA

wow! stop everything else now and look this amazing page about concurrency programming in C! 🙀 https://t.co/J65ZbHw9e3 thanks leo! 🍕

Came up with a working set of instructions for PC-relative calls and address calculations for my V16 ISA. +/-2MB range w two instructions (32 bits of code), and full 4GB range w three instructions. Also perfectly fusable. Struggling somewhat w aligned relocs in binutils/bfd.

The first V16 program in the world! Hand-assembled in a hex editor, disassembled with binutils, nothing to run it on, and it's a pretty meaningless program (the prologue/epilogue isn't even needed), but still 🥳 Forgot how cute 16-bit instructions look 😅 #CPU #ISA

Your operating system, your browser, your database engine, your web server, git, your JavaScript engine, your Python interpreter… all of these are likely written in C/C++. I repeatedly encourage people to learn many programming languages. I do not (at all) think that C or C++

wow! this is really gold! 🥇 https://t.co/1yWVhXphPZ

Trying a new ISA targeting the very low end (think AVR, Cortex M), but with a twist. Only at the concept level right now: https://t.co/X1NDWCBXOb Still not convinced about the 16-bit instruction encoding, but I'm fairly confident about the vector functionality.
