@ASCII-only Any idea why ≧⁻∕ΣθＬθθＩ∕θＸ∕ΣＥθＸι²Ｌθ·⁵ is rounding its output? ≧⁻∕ΣθＬθθ≧∕Ｘ∕ΣＥθＸι²Ｌθ·⁵θＩθ works but is less golfy. If you need to fix something, please also consider vectorising Power, so I can write ≧⁻∕ΣθＬθθＩ∕θＸ∕ΣＸθ²Ｌθ·⁵

Specifically, you were supposed to write a program that would output 2016 (or whatever the year was); and where if you changed any single character, it would either be a build error, or still output 2016.
I didn't find the challenge when I searched for it.

@wizzwizz4 interpreted. better = gives you more control over the implementation

I'll throw my ring into the hat.
Compiled is better because it lets you pretend that you're using a real programming language.

Nah, actually I'm going to concede; interpreted languages have more scope for self-modification and non-standard execution fun stuff.
@EriktheOutgolfer I actually laughed at that one.
 
ngn
ngn
there's a third option - semi-compiled, semi-interpreted, i.e. compile to your own bytecode format and write a vm to interpret it
 
wizzwizz4
wizzwizz4
@ngn That's what Python does, isn't it?

@ngn i'm quite the opposite :p
 
wizzwizz4
wizzwizz4
11:55 AM
@dzaima Same.
 
feersum
feersum
My most common situation is to get mad that the existing interpreters are all unsuitable for some reason and be forced to implement my own for some challenge.
 
dzaima
dzaima
@feersum that's.. currently my case for java, C, JS, APL & pretty much every language I've used, but I certainly don't have the patience to make my own versions of literally all the languages :p
 
ngn
ngn
@feersum by unusable you mean too verbose?
 
dzaima
dzaima
Canvas was made because SOGL didn't meet my requirements, and for a while i've been gathering ideas for a 3rd ascii-art language because it too is a bit bad
 
feersum
feersum
@ngn No, how would that work? If you have something less verbose, it must be an actually different language.
 
dzaima
dzaima
11:59 AM
@ngn all verbosity problems can be fixed with a good enough ide :p
(and yes, making my own ide(s) is on my infinite non-existing todo list too)
 
ngn
ngn
@feersum i see, so most commonly you reimplement existing languages. which ones have you done?
@dzaima "every feature of your ide is a defect of your language" - i always forget whose quote that was...
7
 
dzaima
dzaima
@ngn I personally though think that features being on the IDE not on the language is a good thing - sometimes the visual representation you want to see is just not the same as the stuff you write
auto-indenting code is one example - you want to be able to write code without worrying about it, but want to be able to visually tell the difference from different scopes.
longer/more logical variable names are (usually) easier for humans to remember, read & correlate, but having to write them out is very annoying, hence code completion.
by that logic, C's undefined behavior is completely horrible as the best way to avoid it is to have tools that tell you about it appearing (besides learning the language well)
 
feersum
feersum
12:17 PM
@ngn Brainfuck (probably more than once) and Stack Cats are ones I recall implementing. There must be more but I can't think of them.
 
wizzwizz4
wizzwizz4
@dzaima It is!
 
ngn
ngn
@dzaima what i usually do is name my variables something very short with a comment on initialisation. long names distract me. i must be developing chronic dyslexia from too much golfing :)
 
dzaima
dzaima
@dzaima but about that, I feel like that there should be a very very simple way (maybe even default) to change all UB to errors for debugging
heh i wonder how much slower would applications be if they checked for UB everywhere
 
ngn
ngn
@dzaima any slowdown due to that would be unacceptable for me :)
 
dzaima
dzaima
@wizzwizz4 ^
 
ngn
ngn
12:28 PM
in practice undefined behaviour is not much of a problem, if i feel insecure about some value, i just add an assert and run my tests in debug mode
 
wizzwizz4
wizzwizz4
@ngn I think you should have a go at FizzBuzzEnterprise.
 
ngn
ngn
if the tests don't catch an offense, i didn't care about it in the first place :)
 
wizzwizz4
wizzwizz4
@dzaima Didn't say it wasn't useful. It's just so incredibly horrible.
 
dzaima
dzaima
@wizzwizz4 as a general rule of advice, if C's UBs cons outweigh its pros for you, you shouldn't be using C.
 
wizzwizz4
wizzwizz4
@dzaima That's why I only use C when I want to stare into the abyss for a bit.
I've yet to finish a C project.
Heck, LLVM's easier!
 
ngn
ngn
12:41 PM
@wizzwizz4 i use clang for the language i'm working on (ngn/k). would there be any advantages (performance in particular) in writing llvm ir directly instead of c?
 
wizzwizz4
wizzwizz4
@ngn Not really.
It makes it less portable, since only clang can really compile it.
 
feersum
feersum
Yeah, I wrote a compiler outputting LLVM IR and afterward realized it was a stupid decision.
I didn't end up using any feature that's not available in C.
I suppose I could add an option to compile with 1000-bit ints :P
 
ngn
ngn
12:56 PM
@feersum what... how 1000-bit ints? avx2?
 
feersum
feersum
LLVM supports ints with any number of bits from 1 to 2^28-1, IIRC.
Language feature idea: When an integer op overflows, recompile the program with more bits in the integer type and then continue execution.
 
wizzwizz4
wizzwizz4
@feersum Outputting LLVM? That's not stupid.
Writing it in LLVM is a little.
But LLVM as part of a compiler toolchain is a brilliant idea.
 
ngn
ngn
@feersum 2^23-1
 
feersum
feersum
@wizzwizz4 It made things much more verbose and hard to debug than if I had outputted C.
 
wizzwizz4
wizzwizz4
@feersum Oh, ok. You didn't run it through the LLVM optimiser?
 
feersum
feersum
1:02 PM
@wizzwizz4 What does that have to do with the concerns I mentioned?
 
wizzwizz4
wizzwizz4
@feersum Less verbose.
 
feersum
feersum
No, an optimizer will make code longer if anything.
Loop unrolling, inlining, etc.
But yes, it was compiled with optimization enabled.
 
ngn
ngn
1:43 PM
i've just been bitten by clang's aggressive optimisation 
#define _0W (~0UL>>1) //0x7f...f
void f(long long v){printf("%d\n",v+1<(long long)(2-_0W));} //falsey with -O1 or higher; truthy otherwise
int main(){f(_0W);}
 
wizzwizz4
wizzwizz4
@ngn That's UB, I think.
 
ngn
ngn
doesn't happen in v3.8, happens in v6.0.1
 
wizzwizz4
wizzwizz4
Yeah, that's UB; you need to write 2LL instead of just 2.
 
ngn
ngn
@dzaima you were right ;)
@wizzwizz4 that doesn't fix it
 
wizzwizz4
wizzwizz4
Ok, _0W is an unsigned long value that represents the largest available signed long...
 
ngn
ngn
1:50 PM
i wanted to test efficiently if a 64-bit value is one of 0x7f...ff, 0x10...00, 0x10...01
 
wizzwizz4
wizzwizz4
Ooh...
You're encountering signed overflow.
 
ngn
ngn
or as they are called in k: 0W ("infinity"), 0N ("null"), -0W
 
wizzwizz4
wizzwizz4
Do the arithmetic with signed integers and you should be fine
I think. I don't really know.
 
ngn
ngn
@wizzwizz4 i decided to just test for the 3 values explicitly and let clang do its thing :)
 
wizzwizz4
wizzwizz4
@ngn Probably for the best. With C, you want to write clear code and let the compiler do the tricks.
 
ngn
ngn
2:00 PM
it's not about signed vs unsigned arith. the overflow was deliberate and it worked previously
the problem was that clang relies on a+b < c <=> b < c-a or something like that
 
wizzwizz4
wizzwizz4
Yeah, I think that's standard C signed UB.
 
dzaima
dzaima
2:41 PM
@ngn what in your opinion would be better: 1) APL interpreter optimizing ¨es out if it can figure out how to; 2) ide telling you to; 3) you're on your own
 
Zacharý
Zacharý
Better for what, the language maker or the user?
 
dzaima
dzaima
@Zacharý user. noone cares about the implementer :p
 
ngn
ngn
@dzaima redundant each-es? like +¨ ? i would say option 3 - that mistake is unlikely to be made, so no need to bloat the interpreter
@dzaima if it's something like f⍨¨ ←→ f¨⍨, i'm not sure (iirc dyalog does this in the interpreter)
 
dzaima
dzaima
@ngn that's why I gave the option of the IDE - doesn't bloat the interpreter, but helps the user. Both simple things like that, but (⍳100)+¨⊂⍳100 vs (⍳100)+⊂⍳100 is a speedup
 
Dennis
Dennis
@ngn It is. v+1 is already undefined for f(_0W).
 
ngn
ngn
2:49 PM
@dzaima there is more than one ide, and some of us prefer vim, so that option is a burden too
 
Dennis
Dennis
-fwrapv seems to be supported by clang.
 
ngn
ngn
@Dennis so ((unsigned) 0xf...f)+1 is not undefined?
 
dzaima
dzaima
also (3/10)∘⊤¨vec instead of ↓⍉(3/10)⊤vec is a thing i certainly would have written a while ago
I could also see f←{10+14×⍵} ⋄ f¨arr sneaking in code after refactorings
 
Dennis
Dennis
@ngn Unsigned overflow is guaranteed to wrap around by the C standard.
 
ngn
ngn
@Dennis well, one learns something new every day :)
@dzaima maybe what you want is an apl linter
 
dzaima
dzaima
2:56 PM
@ngn the ide can also serve as a linter

Yes, -ftrapv detects signed integer overflow. Useful for debugging.

Wow, very impressive.
Though I guess it also depends on how heavy each test is. My workplace has a test suite with something like ~200 tests that take about 10 minutes to run all the way through.
 
ngn
ngn
@wizzwizz4 fyi, indeed it looks like clang optimised properly my new stupid version of the code (3 comparisons with ==): 
	movabs	rax, -9223372036854775807
	add	rax, rdi
	cmp	rax, 2
	ja	.LBB1_2
^ essentially what i was doing by hand before
 
mınxomaτ
mınxomaτ
3:20 PM
@El'endiaStarman Each test suite (~500) sets up and tears down a copy of the app. Network access is mocked, and it all runs on a few NVMe RAIDs. It's an expensive setup, but it made a huge difference in test times.
 
wizzwizz4
wizzwizz4
@ngn Compilers are smart nowadays. Never forget it.
 
Dennis
Dennis
Well, some are.
 
El'endia Starman
El'endia Starman
@mınxomaτ Sounds like our setup dialed up to 11. We setup/teardown nearly everything for each test and everything external, especially network access, is mocked. Setting up and tearing down definitely contributes a lot to the time it takes, but it does also mean each test can assume a clean slate, which is convenient for the devs.

I forgot that gotos were well-defined.

@primo you're using xem's decoder for solutions <300 bytes (roughly) right

- a hat that is given every time you edit the description of the hat on the secret hats post
- a hat that is given whenever you reply to yourself in chat
- a hat that is given for opening/closing the devtools 100 times in a row

- a hat given when you click where the flag button should be but youre actually logged out and then you log in
now that's Relatable
each hat should not attempt to encourage good behavior, but to mock and ridicule you for the mistakes you make every day

Clearly you should get a hat for getting your first hat
 
quartata
quartata
they already did that one
try this:
- a hat given when your first hat is obtained on the very last day of winterbash
dont even make this one a secret hat.
you want people to decide whether to sacrifice all of winterbash for one hat

You should get a hat for performing an even positive integer of actions on a page without refreshing.

@ASCII-only I was thinking that, but then you could see the JavaScript.
I was also thinking "answer with a non-prime number of characters" but then people would know it was answer-related.
A secret hat that appears pretty much randomly, though?
