Q: Is the number sum of 3 squares?

Challenge Write a program (function) that given a nonnegative integer input, output whether the number can be represented as the sum of 3 square numbers. That is, the program should, given nonnegative integer input \$N\$, determine whether \$N=a^2+b^2+c^2\$ where \$a,b,c\$ are all nonnegative int...

function fact1(x) { return x<1?1:fact1(x-1)*x; }
function fact2(x) { var s=1; while(x>1) s*=x--; return s; }

@emanresuA about your golfing suggestion, I think you should post that as your own answer because it's pretty different to what I would have thought to do. It's your 6 bytes, not mine :p

I tend to avoid posting this sort of brute-force FGITW answer - feel free to take it yourself :p

@RubenVerg Right, but argument is restricted to rank 3 in this case.

Q: Ranking of binary trees

Let N = [0,1,2,...n-1] be the initial segment of the natural numbers of length n, then all permutations of N can be sorted lexicographically, starting with the identity. The index into this sorted array is known as the rank of the permutation. For example, the permutations for n = 3 can be seen i...

help i'm blanking on a term

in bash and relateds, you can use the output of a command and have it be output to temporary file descriptor, such that commands that only operate on files given to them as args can be piped to, what is this called?

Process substitution

In computing, process substitution is a form of inter-process communication that allows the input or output of a command to appear as a file. The command is substituted in-line, where a file name would normally occur, by the command shell. This allows programs that normally only accept files to directly read from or write to another program. == History == Process substitution was available as a compile-time option for ksh88, the 1988 version of the KornShell from Bell Labs. The rc shell provides the feature as "pipeline branching" in Version 10 Unix, released in 1990. The Bash shell provi...

that's it thanks

Don't thank me, thank… the internet‽

i know who i won't thank

I once again find myself with two tabs of TNB open

I thought I'd gotten past this

but alas, (or to some, whatever the opposite of alas is), I find the allure of this room compelling me to have it open multiple times once more

Themoonisacheese

my way of fixing this is having TNB on a pinned tab, so if i see a full-width TNB tab i know it's an extra

mousetail 'he-him'

Those are rookie numbers, I have 14 tabs of TNB open (I am actually every person in this room)

that won't work, my full length tabs are narrower than my pinned tabs

mousetail 'he-him'

Seek help

Themoonisacheese

i genuinely don't understand opening that many tabs

mousetail 'he-him'

I open that many tabs sometimes but every now and then I go on a killing spree and close most of them

Themoonisacheese

when i was like 13, i remember seeing ads for google chrome (like IRL ads) that were saying stuff like "baking a cake? 1 hours, 36 tabs and no slowdowns later, Lisa made it with the help of Google® Chrome™" and like, why was she opening 36 tabs for a cake recipe

mousetail 'he-him'

25 wikipedia tabs for the chemistry of various ingredients and tangents thereupon

the main point was that chrome could suspend tabs and have many tabs "open" but leave ram free in a time where 4 Gb was a lot of ram, so maybe it's just that i grew up with computers that would grind to a halt if you dared open 3 internet explorer tabs, but i just don't need that many tabs

mousetail 'he-him'

I remember when I needed to always close my browser to be able to run games at a reasonable fps

att

ok tbf i don't usually open that many tabs in a single window

Themoonisacheese

i remember using tools that would kill and then restore explorer.exe while games were running because i was so strapped for ram

Ginger

@mousetail'he-him' I still need to do that at times :p

Neil

I remember when web pages were so light that I could have hundreds of tabs open

Ginger

I mean, some still are

my website has almost no JS on most pages

mousetail 'he-him'

Enough CSS or large images can make a page slow with no JS needed

Ginger

don't got those either :p

Question for anyone who has read at least the homepage of iogii (golfscript.com/iogii). Do you know what the world "iogii" means/refers to?

Apologies for the self serving question, but I suspect no one will know and wonder if I should make it more obvious

Themoonisacheese

@DarrenSmith ^

oh nevermind

are you not the creator of golfscript?

Darren Smith

yeah

Themoonisacheese

nevermind again, you're testing us

sorry i'm a bit slow

Darren Smith

well testing myself really, I think it is too difficult to get since there is no hint

Themoonisacheese

no idea tbh, then again it took me an embarassingly long time to figure out previous, so maybe i'm not really the perso nfor the job

the only thing the name evokes is "Uiua" but i don't see an easy mapping between the 2 names

unless you mean literally en.wikipedia.org/wiki/Yogi but that sounds a bit obvious

Darren Smith

Alright thanks! I think the hint is way too subtle, was hoping it would be like an easter egg, but I think it's one no one would ever notice lol

i really like the trees in the interpreter btw

Darren Smith

Thanks they were fun to make, couldn't get boxes around functions like I wanted though with that library

Themoonisacheese

good news! i don't know hwo you wanted them so i just think they look neat :D

@mousetail'he-him' weirdly this has actually never been a thing for me unless my computer's been on for, like, way too many consecutive days without a reboot

and then closing browsers barely even help at that point

@DarrenSmith Yeah, "yogi" is all I could guess too
