A PDP-11/40 on a $100 microcontroller board: p2-11 boots Unix V6 and RT-11 on a Parallax Propeller 2, and V6 compiles C with its own cc. Written in OctoGo, my Go-like language where a goroutine is a core. Built with a lot of AI help. #golang

loadp2 is used to load programs to the memory of a Parallax Propeller 2 ("P2") chip over a serial connection.
Switching to a DFA matcher in a particular, real world user case.
* Compile Time: The DFA is significantly slower to compile (~200x).
* Match Time: Once compiled, the DFA approach matched ~28x faster than the standard library.

Taming the Flat AST: Ergonomics in the Age of Zero Allocations
How to use egg's flat []int32 ASTs and stay sane.

Meet egg: A new LL(1) parser generator for #Golang. It generates parsers from standard EBNF but uses a unique "flat AST" (just a []int32 slice) for high performance and low GC pressure.

qbecc is a C compiler producing Go ABI0 assembler.
The resulting assembler code runs on standard Go movable stacks.
It's research tool to compare modernc.org/ccgo/v4 and qbecc with respect to performance.
The proof of concept has reached v0.1.0: pkg.go.dev/modernc.org/qbecc
A toy example of using modernc.org/nerdamer in a modernc.org/tk9.0 application

Pure Go QuickJS now supports FreeBSD, Linux, MacOS and Windows

modernc.org/tk9.0 has a new MacOS appbundle tool
The tool gets rid of the additional, automatic opening of a terminal window when the application is started from the GUI by double clicking or similar ways.
