cmc: write a program that terminates with a "catastrophic failure" error

What is a "catastrophic failure" error?

Q: Shortest code to throw SIGXFSZ

Q: Piet (Mondrian)'s Puzzle

For more information, watch this video. The Mondrian Puzzle (for an integer n) is the following: Fit non-congruent rectangles into a n*n square grid. What is the smallest difference possible between the largest and the smallest rectangle? For 6, the optimal difference for M(6) is 5, and can be...

"Catastrophic failure (Exception from HRESULT : 0x8000FFFF (E_UNEXPECTED))"

a native error output by the interpreter including the words "catastrophic failure".

@GabrielBenamy javaScript: CatastrophicFailure

Error is: ReferenceError: Can't find variable: CatastrophicFailure

Gabriel Benamy

I said native error

@Downgoat Sort of. vihan.org/p/tioclient/?l=python2&p=KyjKzCtRKEosj8/…

.__.

peramlink are weird

lemme redo unicode

Dennis

All of it, please. In case it helps: Before permalinking, the input was showing the goat, the output a = sign. After permalinking, the input is gibberish, but the output is correct.

@NewMainPosts out of all the signals that it's interesting to try and throw, I wouldn't think that SIGXFSZ would be one of them

Downgoat

4:35 AM

why can't JS just use UTF-8 by default like rest of world :(

ais523

maybe I'm wrong though

I thought SIGILL would be fairly uninteresting and I was wrong about that (the Swift answer was interesting, at least)

Qwerp-Derp

OK SE's Clojure highlighting is borked

ais523

SE's highlighting of most languages is borked

nowadays when I write a solution in Perl, I consider it something of a mark of shame if SE's highlighting of it is anywhere near correct (and then, when it comes to the explanation/ungolfed version, use carefully worded comments to ensure that mishighlightings don't persist from one line to the next)

Qwerp-Derp

True, apparently Perl's highlighting is borked

A: Sandbox for Proposed Challenges

Convert String to Integer without built-in functions. The challenge is to take a string input, such as "1234" and convert it to a number, 1234. This must be done without type-casting, int() calls, or anything of the such. I'm not really sure what the best way to specify that i want something l...

4:38 AM

Aren't the comments in Perl's highlighting borked?

ais523

to be fair, syntax highlighting Perl is formally undecidable, but most of the programs I write aren't nearly that hard to highlight

Downgoat

@Dennis TIO response is UTF8 right?

Dennis

I hope so.

ais523

(Perl allows you to write arbitrary parser hooks in Perl; they modify the parser as soon as they're seen, and the subsequent code is parsed with the new parser)

Downgoat

@Dennis .______. :|

@Dennis no it is not

Dennis

4:43 AM

I'm pretty sure it is.

Downgoat

i removed UTF-decoding and it worked

H Walters

Speaking of unhighlightable, are there any golfing languages which use abstract symbols that are arithmetically encoded into character sets? Or has someone even had the idea (not that I've actually tinkered with golfing languages, but was curious)

Downgoat

that is unless XMLHTTPRequest performs the decoding itself

ais523

@HWalters I've had an idea fairly simple for that for a golfing language I'm working on

the programs are floating point numbers, given to a certain accuracy; the accuracy corresponds to the length of the program, the value to the content

this means that a program can contain a fractional number of bits

(there will also be a method to represent them as bits and/or as bytes, rounding up, for people who don't believe that an approximate number is valid as a program)

H Walters

That sounds like a meta post in planning in itself

(Do you get to score to the fractional bit or must you round up to the nearest bit?)

@Downgoat on my computer when first load permalink, cursor is weird like superscript

Downgoat

can you do a screenshot?

Maltysen

as soon as I start typing anything, it fixes

Downgoat

waaaat

this is not my fault though luckily

Maltysen

btw everything else looks awesome

Downgoat

@Maltysen okay, can you try now?

@Maltysen :D

Maltysen

4:52 AM

nope

Downgoat

:( hmmm

Maltysen

btw none of the language links work?

Downgoat

okay, can you try doing to vihan.org/p/tio and see if you can see a cursor on empty line?

@Maltysen language links? Can you see error if in console?

Maltysen

@Downgoat same issue it starts out small, I start typing it gets bigger

Downgoat

@Maltysen every letter gets bigger and bigger?

Maltysen

4:53 AM

no

first one fixes it

Downgoat

ok

will debug

Maltysen

style.js:107 Uncaught URIError: URI malformed

Downgoat

DAMMIT

Maltysen

that's when it loads

Downgoat

@Maltysen can you try clear caches and reload?

Maltysen

4:54 AM

not the links, those don't error

Downgoat

ok i think i fix

I assume by language links you mean the language list on the left

Dennis

@Downgoat XMLHTTPRequest does whatever the web server tells it to and returns a string using the specified encoding.

Maltysen

yay fixed

feersum

Does whatever a web server tells it to?

That sounds unsafe.

PhiNotPi

5:18 AM

Most unsafe web thing I've done was that KOTH server.

Running arbitrary code with literally no sandboxing.

Dennis

@feersum I meant regarding the encoding. XMLRequest returns decoded text, not a bytestring or a bytearray.

In TIO's case, it also gunzips the response.

H Walters

Oh, by the way @Mego I saw your starred comment yesterday, and apologize for my "homework" question :)

@HWalters If memory serves, it wasn't your question that prompted that comment :P

Anonymous

The question that prompted it has been launched into the sun

H Walters

It wasn't but I was amused by the comment

Actually, my impression was that it was a homework problem trying to pose as a challenge... mine is a challenge using fictitious homework as a gimick

Anonymous

Oh you posted the Martian homework challenge

Anonymous

I thought you posted the other homeworky challenge I was complaining about

Anonymous

Yeah I liked that one :)

Maltysen

5:49 AM

@Downgoat ctrl-enter still doesn't work

you can detect a key down with the correct keycode and modifier of ctrl

ais523

@HWalters most of the resulting Martian doesn't seem very intelligible, and even if not technically repetitive, it does seem to become quite familiar after a bit…

H Walters

@ais523 Good thing it's not an "Ultra-Martian" challenge then

(FYI, once Flourney's book was published, Catherine was to say the least not impressed; some time later apparently there was another language she channeled called "Ultra-Martian" which was more pictographic than phonetic)

Or maybe I'm shuffling the history a bit in my head

Yeah, Ultramartian apparently is already in the book

I had an idea for a challenge

@DestructibleWatermelon tell us

Destructible Watermelon

6:57 AM

Take input n, convert n to words, convert to 1337 5P33K, remove non numeric chars, print

Or return

Whatever

betseg

Wow

Destructible Watermelon

EXample: 1 -> one-> 0n3 -> 03 -> 3

Or maybe 03 is fine. Idk

@betseg ?

betseg

How many digits can n have

Destructible Watermelon

Idk.

Some reasonable limit

Hmm... Does anyone know of an engine for Kleene's original ("formal") regex?

Anonymous

(where only |, (, ), and * are metacharacters)

Anonymous

I'm sure there are dozens of implementations, but Google is being unhelpful

feersum

Why can't you use a more complicated regex engine and simply ignore the extra features?

Anonymous

@feersum Because I'm looking to answer codegolf.stackexchange.com/questions/102018/…

I have an idea of how to construct a polyglot using Kleene regex along with modern regex, but I'd need an existing Kleene regex implementation
