This weekend's hack: How long does it take to brute force a cryptographic key? bruteforce.bitsnbites.eu

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 codeberg.org - 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 medium.com/@john_25313/c-…

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

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…

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++…

Trying a new ISA targeting the very low end (think AVR, Cortex M), but with a twist. Only at the concept level right now: gitlab.com/mbitsnbites/v16 Still not convinced about the 16-bit instruction encoding, but I'm fairly confident about the vector functionality.
