The Colorado Code - Futo Ret Alpha Release

This was posted ten days before I wrote this post: Curious Marc - HP LED Display Programmer but I didn't see it until now. See also this post: The Amazon Code (2012).

Daniel Cook: "This is a minimal assembler+disassembler+CPU emulator that runs entirely in the browser through WebAssembly. It supports Arm32, Arm64, [and Arm32 Thumb], x86, and RISC-V. There's also some examples to play with if you're new to an architecture or low level assembly in general". See https://ret.futo.org/ and https://github.com/futo-org/ret. Feedback on the Zulip post: they're thinking about doing a rewrite.

It uses Keystone for assembly: "Keystone is a lightweight multi-platform, multi-architecture assembler framework," Capstone for disassembly: "Capstone is a disassembly framework with the target of becoming the ultimate disasm engine for binary analysis and reversing in the security community" and Unicorn-wasm for emulation: "Unicorn is a lightweight, multi-platform, multi-architecture CPU emulator framework based on QEMU". Compiled with emscripten: "Emscripten is a complete compiler toolchain to WebAssembly, using LLVM, with a special focus on speed, size, and the Web platform". Keystone is based on the LLVM-MC component not the full LLVM toolchain.

How Could One Unify CMU and MIT

I mean, how to get the best of the two different philosophies of computation. One is based on typed programming languages and the other on engineering with diagrams . This is about practical computing and the cost and feasibility of software development in general. Here is the problem: We have a lot of algorithms which can all be described abstractly using some sort of pseudocode, or perhaps using some particular language (usually Python!). These algorithms are often well-studied and a lot is known about them in terms of their computational complexity in time and space. Substantive practical software systems invariably employ many such algorithms, often implemented in libraries with more or less well-specified APIs. But very few of these libraries are capable of interoperating because they are either packages written in some specific programming language like Java or Haskell, say, or they are written in C and used as object code, or they are written in an interpreted language like Sc...

Tensor Fields and Simplicial Complexes

Listening to Freya Holmér last night I started to get glimmers of an idea I had long ago about how to represent vector spaces in computational processes using this recursive abstract type :  abstype 'a point = POINT   of {getx :  'a vector,       diff :  'a point -> 'a point,       move :  'a point -> 'a point,       scale : 'a -> 'a point,       proj :  'a point -> 'a} with    fun new i (op +) (op -) (op * ) dot =    let fun self x =  POINT       {getx = x,        move = fn (POINT pr) =>           (self (x + (#getx pr))),        diff = fn (POINT pr) =>          self (x - (#getx pr)),        scale = fn i =>          (self (x * i)),        proj = fn (POINT pr) =>     ...

Just testing stuff: SVG You can click on the blue circle: MathML There is not much you can do with this. See Mathematical Markup Language 1.01 Specification   7.1.5 Mixing and Linking MathML and HTML . It's the big problem  of how you compose languages.   a x 2 + b x + c = 0 You can click on the discriminant: x = − b ± b 2 − 4 ⁢ a ⁢ c 2 ⁢ a 2D Canvas Sound  Beep!
