eth-zvm is an experimental implementation of the Ethereum virtual machine in pure Zig. I probably won’t implement the whole thing, but it’s a fun way to play around with Zig on a project where Zig does seem to actually be the right tool.

Added the ability to overwrite existing memory withing the virtual machine
Added support for the POP opcode
Added support for the CODESIZE opcode
Added support for the MUL opcode
Moved debug printing to the memory module
Moved memory offset and size checks to memory module
Switch to the +% operator to more clearly express addition with overflow allowed
Fixed a bug in MSTORE opcode
Print gas consumed after each instruction for debugging
Improved formatting for the STOP opcode
Fixed some bugs on evm.codes, not my site but a great reference for the EVM
- Fixed gas calculations for keccak256
- Fixed the keccak256 playground example

PicoShare

PicoShare is a minimalist web-based file sharing tool I’m working on. I’m often frustrated that I can’t just send someone a link directly to a file because every file-sharing service tries to re-encode images/video or wrap their own viewer around other files, so I’m making a simple self-hostable tool that lets you upload files and share them with other people.

Reviewed a PR to add a download count

Misc

Submitted my first PR to the Zig programming language
- I refactored some tests based on my approach to unit testing
Decommissioned a bunch of old home video tapes
- I’ve already digitized them, so there was no need to keep the originals.
Submitted an improvement to base.org’s PR template
