# Stochastically Observed Computing Kaleidoscope

Sock is a bytecode vm that features just enough to be able to do "meaningful" computing of things. Constructed entirely in C, 

using 4 standard libraries and in around ~140 LOC.

## Compilation & Duration

`gcc -static -march=native -mtune=native -s sock.c -o sock`

As compiled with GCC 10.0.1, `bdver2` architecture, 16GB RAM, running `time ./sock test.sock` yielded:

```

real    0m0.042s

user    0m0.015s

sys     0m0.015s  

```

## The Features

* 16 instructions

* 2048 bytes of memory

* 4 8-bit registers

* Subroutine support (only 1 level)

* Around 4 modes of operation (number, register, memory, memory number, and some mixing)

* VM halting through exploitation of return instruction (0a, turned to 3a will halt operation)

* File reading

* Jumping, program self-modification potential

### But why?

I challenged myself to write this in one day. I love this sorta stuff xD
