The Nineteenth Byte

12:00 AM

^ we're all here :P

I've come up with a new language with only two symbols: "A" and "B". "A" returns a function that accepts any program, and determines if it finishes. "B" returns a function that compiles my new language.

I have both a language spec, and a compiler!

time to use it on PPCG

That feeling where you think of a few bytes you can golf out of a solution, but have to wait through a full workday before you can implement it.

I really like R

Alex A.

Are you the one who said you were downloading it or was that quartata?

I really can't recommend RStudio enough for anyone who wants to use R.

Just recently I've been noticing a lot of really old challenges getting dredged up back to the home page for some reason

Anyways

A: Find the absolute value of a number without built-in functions

Rotor, 2 bytes sS Challenge predates this language by two years, so this isn't competitive. Squares input and then square roots it. Nothing special.

It isn't like I've given up on Rotor or anything

I'm getting sick of answers like this on that challenge

1. On most modern Linux systems you need --no-preserve-root for this to actually do anything. 2. Since it uses sudo, I can just simply CTRL-D or enter my password wrong and it won't execute. 3. Bash builtins would still work. — quartata 1 min ago

So I'm trying to compile GHC from source

@Dennis APL question for you. Say I have an array like 6 3 3 10 0 2 4, for example. I want to start a variable X at some value, say 5, and for each element of the array, do X = 6*X + a[i]. How do I... how?

Self-hosting

The term self-hosting was coined to refer to the use of a computer program as part of the toolchain or operating system that produces new versions of that same program—for example, a compiler that can compile its own source code. Self-hosting software is commonplace on personal computers and larger systems. Other programs that are typically self-hosting include kernels, assemblers, command-line interpreters and revision control software. If a system is so new that no software has been written for it, then software is developed on another self-hosting system and placed on a storage device that the...

Self-hosting langs are supposed to be able to bootstrap themselves

Alex A.

Not necessarily I think

Anonymous

From the docs:

Anonymous

In particular, you need GHC installed in order to build GHC

Anonymous

How the hell am I supposed to get ghc if it's not in my package manager, then?

quintopia

As I understand the term, no lang has ever "bootstrapped" itself. Sure, they can compile or interpret themselves, but some other lang is needed at some point to build the initial machine code (even if said lang is the machine code itself)

Anonymous

@quintopia Bootstrapping means building itself once using other tools (often with minimal features) in order to fully build itself using itself

@Mego Ah, so something can bootstrap itself using something else. Well okay then.

@quintopia PyPy does that. It builds a minimal version of itself using gcc and regular old Python, then fully builds itself with that minimal version.
