The Nineteenth Byte

that's not a good

especially when it's from trying to click on the file explorer

@NewPosts Very unfortunately, Brachylog's ẋ doesn't work in reverse--looks like an infinite recursion error.

😭

It's okay, I've got a 6-byte solution

which is surprisingly pretty fast, at least for the given test cases

nice

imagine not timing out for anything larger than a 2x2 matrix

I noticed a peculiar thing about Windows Console.

Namely, it cannot display ♢ (U+2662) properly even after setting the correct encoding.

@lyxal faster is also shorter in mathematica :)

that's powershell

so far faster is 1 byte longer in jelly 😭

that's command prompt

Q: Weave two lists, cycling if necessary

...i didn't notice jonathan allan also has a completely different faster 12-byter

Consider two lists, A and B. To weave them together, we take the first element of A, then the first element of B, then the next element of A, the next element of B, and so on, ending with the last element of A. A = [1,2,3,4,5] B = [6,7,8,9] A weave B = [1,6,2,7,3,8,4,9,5] This process works as d...

I think there's a fair amount of untapped potential in Acc!! golf. I haven't had the patience to write especially complex programs in it, though.

I have an integer X that 1<=X<=N. You can provide a set and ask if X is in it. I may lie but at any time there's not more lie than truth. How small set can you guarantee X is in?
E.g. if N=100, by asking set [1,50] you can know a set of size 50. First answer must be truth, otherwise lie(1) is more than truth(0).

E.g. second answer may be truth or lie[in this case lie(1) is not more than truth(1)]

Q: Interpret PlusOrMinus

PlusOrMinus is an esoteric programming language invented by Esolang user PythonshellDebugwindow. Language specification There is a wrapping byte accumulator (incrementing 255 results in 0 and decrementing 0 results in 255) in the language. There are two instructions in the language: +, which inc...

Fun fact: 100 out of every 100 bugs is a programmer's fault

Ginger

wrong, once a cosmic ray made me accidentally add a keylogger to my program

Seggan

thats also a programmer's fault

someone misarranged the CPU causing the cosmic ray to hit that one critical spot

and the CPU was designed by a program thereby being a programmer's fault

Ginger

no, it hit me in my brain :(

still your fault

I'm pretty close behind you--just need 28 more score

It's interesting looking at the gold tag badges that aren't code-golf.

The easiest one to get is string, followed by math and number. The latter two are mostly just the top site users, but each of them has one sub-100k outlier, and interestingly, they're different outliers (alephalpha has math, Emigna has number).

Unsurprisingly, stasoid is the only one with a gold polyglot badge.

Gold tag badges have been awarded for 13 different tags so far, and Dennis has 10 of them.

@DLosc if anyone else had a gold polyglot badge i would be shocked

LOL--as a matter of fact, nobody else even has a silver polyglot badge.

Aiden Chow

6:57 PM

@DLosc ok thats a bit surprising actually

Outside of the top 8 site users, the only ones with non-code-golf gold tag badges are: alephalpha, DJMcMayhem, Emigna, ETHproductions, Lynn, nimi, ovs, Shaggy, and stasoid. Emigna is the only one with more than one (number and string).

meanwhile I don't even have a silver tag badge :p

@mathscat i only have code golf silver badge lol

Any feedback? In particular, is my spec of the regex format clear enough?

According to your current spec, (a|b)* from the test cases is incorrect; it should be ((a|b))*

Whoops, fixed

You might also want to explicitly state that something like ((a)) doesn't have to be handled. It's implicitly excluded by the syntax rules, but somebody will probably ask about it.

It's definitely a good idea to use a more consistent format, but that has the side effect of me occasionally forgetting I'm using it

@DLosc Added

@emanresuA Next challenge idea: Generate all valid regexes in this format ;)

I don't know if it would necessarily trip anyone's solutions up, but something like (((a)?|b))* and/or ((a)?(b)?)* might be good for completeness

10:22 PM

Those are both equivalent to ((a|b))* right?
