В нём задачи решают тройкой: доменная виртуальная машина VM, доменный язык программирования DSL и алгоритмы на нём. В этом курсе удачными фрагментами разных заметок доступно объясним причины многообразия языков и преимущества их разработки. С теорией, историей и примерами. Вся наша работа строится вокруг VM, DSL, EBNF, отношений и графов. Мы увидим, как эти объекты соединяют вместе, получая вычислители и программы.

Minecraft를 Brainf*ck 언어로 구현한 첫 사례라고 주장하며, 1,200만 줄 규모의 Brainf*ck 코드로 지형 생성, 블록 물리, 이동, 전투, 몹 AI, 인벤토리 등 게임 핵심 기능을 동작시킨 프로젝트를 소개한다. 매우 необы한 오픈소스/개발자 작품으로 보인다.

Ever wanted to program hardware with Brainfuck? Well now you can with Brainfuino, the only microprocessor to use this minimal programming language as its instruction set. Rev 1.1 is significantly faster than Rev 1.0, so there's no better way to run your code.

Production of Rev 1.1 is now complete and we're now selling them locally. Online orders are pre-orders for now, until local friends have been given a chance. If we have a lot of interest, we're considering another larger production run.

Credit to Matthew Archibald (@Archibald_M) for Rev 1.1 improvements and production and Eduardo and Ignacio Corpeño for Rev 1.0.

Pictured are 7x Brainfuino [-]+ Rev 1.1 complete with cases, 5x Brainfuino [-]+ Rev 1.0 PCBs, and a Sparkfun RedBoard (Arduino Uno clone) that I used for many projects in high school.

So I was at some point really into PDP-8. Single-byte instructions (8-ish of them,) 12-bit words, single register, small memory, basic drivers. Yet people managed to accomplish some really impressive feats with it, like writing an #OS. It was part of my inspiration for OS.bf in #Brainfuck.

And now that I’m eyeing this cute and super basic calculator with a single memory register, I start recalling. The days I used PDP manual as reading on the bus or in university locker rooms. The attempts to reconcile #Lisp syntax and PDP instruction set. The wish to build a computing infrastructure atop this infinitely tiny foundation.

I keep justifying this calculator purchase to myself, while I should’ve just learned #Fractran instead.

Presenting Brainfuino [-]+ Rev 1.1, the Brainfuck microcontroller!

My Christmas present from @Archibald_M has arrived! I'd been wanting a Brainfuino for years now, an Arduino-like microcontroller that only runs Brainfuck programs, but they're not sold anywhere. So, Matthew took up the challenge to understand Eduardo's design, manufacture the PCBs through JLPCB and source the parts. He even fixed some issues in the original design, like the unstable clock, and made improvements, like swapping USB Micro-B to USB-C.

We'll be selling our extra stock soon, to recoup the costs. Stay tuned.

Going to dissect Tritium (probably the fastest #Brainfuck #compiler out there) today evening and share the findings here. I don’t expect much from that, because previous dissection attempts didn’t end resultative. But still.

Might be useful to Brainfuck / esolang optimizer / compiler folks. Including me with my Reb, a regex-driven compiler and optimizer <https://github.com/aartaka/reb>

A thread that will continue in roughly eight hours 🧵
