The Nineteenth Byte

@Bbrk24 now there's a challenge I haven't seen in a while

good times

        ; As outlined in turing_completeness.md, there will be a code thread and a memory
        ; thread. The nature of Trilangle makes it far easier to emulate a Harvard
        ; architecture.
    TSP memory_start
        ; Read input until EOF, keeping track of how much was read.
    PSI #0
input_loop:
    GTC
    BNG input_done
    SWP
    INC
    JMP input_loop
input_done:
    POP
fde_loop:
        ; Fetch-decode-execute cycle, but weirder.
        ; Fetch and decode each instruction, but send it to the memory thread to execute.

I assume the fact it's output only makes it much easier :p

Bbrk24

Yes. Trilangle can only take input from one source, so it'd be impossible to distinguish program from input

lyxal

> ~: Push a random integer in any range of integers. Minimum range of 0 through 32768

man what on earth was I thinking back then

ain't no way that's a good golf built-in :p

Bbrk24

I like the C JIT one that copies strings into function pointers

Kotlin is longer than Java in that one @Seggan

My Trilangle version here would exit with a floating-point exception on divide by zero and a segfault if you operate on an empty stack

lyxal

12:24 AM

/: Divide. 0-division will result in an error.

and erroring on empty stack is fine

Bbrk24

Yeah, Trilangle's DIV delegates to the native integer division instruction, and at least on Windows x86 that causes a floating-point exception on divide by zero (which terminates the program)

CMLDQ: Should I add a -q flag to switch from a stack to a queue?

Bubbler

if the only storage becomes a queue then it is significantly harder to program in general

Bbrk24

it actually makes the code significantly more complicated because I have to check a flag before every write into the storage

using _Scary_val = _String_val<conditional_t<_Is_simple_alloc_v<_Alty>, _Simple_types<_Elem>,
    _String_iter_types<_Elem, typename _Alty_traits::size_type, typename _Alty_traits::difference_type,
        typename _Alty_traits::pointer, typename _Alty_traits::const_pointer, _Elem&, const _Elem&>>>;

Bubbler

if something makes things harder for both you (the implementor) and programmers, it's probably not a good thing to implement

Bbrk24

Thank you MSVC very cool

other than pure esolang vibe

Damn they made Verbosity into a prac lang huh?

I like how it's called _Scary_val

Q: Interpret Volatile

Interpret Volatile Volatile is a stack-based esolang made by A_/a'_'/A that only has 8 instructions and is turing complete. However, it is also non-deterministic... meaning that programs don't always give the same output. Your task is to interpret this language. Language specs Taken from the ...

Q: Resultant of two polynomials

The resultant of two polynomials is a polynomial in their coefficients that is zero if and only if \$p\$ and \$q\$ have a common root. It is a useful tool for eliminating variables from systems of polynomial equations. For example, it is used in my answer to the code golf challenge Add up two alg...

@mousetail i know what the words mean individually, but not together in that order.

Asking once is plenty

As in once is enough asking, no need to ask more than once

PlaceReporter99

@mousetail ok

anyways, do you have any feedback for the sandbox post?

@RydwolfPrograms looks good in theory, but hard to read in practice

plus, doesn't seem to include more niche unicode characters

which is kind of a must-have given the site we're on :p

Everson Mono is good font support, but at smaller sizes it’s not perfectly even for some reason

bizarre

Bbrk24

It also has weird licensing terms: you can have it for personal use on one computer for free; you can pay $25 to use it on three computers; and if you want to use it on more than three, you have to reach out to him directly.

Unrelated String

Q: Why does integer division by zero result in a floating point exception?

Division by zero in a C program results in abnormal termination with the error message Floating point exception (core dumped). This is unsurprising for floating point division, but why does it say this when integer division by zero occurs? Does integer division actually use the FPU under the hood...

@RydwolfPrograms i kinda hate how the braces look but in service of increased legibility for those who need it i'm really impressed someone managed to come up with them lmao

@RydwolfPrograms what a desirable bug! I better implement that bug in my programms!

And now I can't repro lol

Actually I can?

It's inconsistent lolll

Okay I figured it out, it's because MathJax automatically typesets on page load by default

God I hate the MathJax docs

@RydwolfPrograms how many net votes before I post my sandbox post to the world?

@PlaceReporter99 Wait at least 3 days

PlaceReporter99

@mousetail and then how many upvotes should I have before I post it?

I mean net votes

mousetail

Around 3 is usually good in 3 days, after a week maybe 2 is enough

If you get a lot of good votes but also feedback it may not be ready

It's possibly the snarkiest paper I've ever read, and it's about proving V - E + F = 2
