@NewMainPosts If you get 2 -1 then a +1, you get 6 rep overall; but if you get 1 +1 and 2 -1, you get 4 overall? (assuming your rep starts from 1)

Hello

@user202729 questions get +5 for upvotes

you'd get a total of +5 for the first case, +1 for the second

I'm trying to golf in perl the expression n*n*(n+1)/2 (basically sum(1..n) * n). My program is $a=<>;print$a*$a*++$a/2 and I'm trying to apply the "reuse assigned variable" rule as such: print($a=<>)*$a*++$a/2, which is indeed a char shorter but I'm not getting the right results. any clue?

(also: 23 chars in ruby, 24 chars in bash (awk)...)

Trying to replace a=gets.to_i;p a*a*-~a/2 to p(a=gets.to_i)*a*-~a/2 is also escaping early on parenthesis as a function call, so I guess 23 is the shortest I can get with this narrow toolset?

I've been working on the repeated digit primes problem and I have a function to repeat the digits of a number: (#~(+0=])@"."0)&.":. Any thoughts on going about implementing the function?

this is in J btw

I've tried recursion but I realized that I can't carry the nth prime, the number of repeated digit primes, and the array of them with me

oh nvm i just realized that i don't need the array

also related, is there a J chatroom? I can't seem to find one

        while (--termIndex) {
            let results = this.find(terms[termIndex], limit, threshold),
                resultCount = results.length;

            addResult:
            while (--resultCount) {
                let result = results[resultCount];
                let matchLength = matches.length;

                while (--matchLength) {
                    if (matches[matchLength] === result) continue addResult;

cole

ping me if you have thoughts on how best to recurse to yield the desired prime (or if you think of a better way)

@Downgoat for time?

for complexity

JS?

5:33 AM

basically I have a function which takes a 'term' and returns a list of matching objetcts in format: { score: ..., value: ... }

I need to run function multiple times and combine those lists

feels pretty simple but like three nested loops seems excessive

user202729

get all into matches then uniqufy?

it tries left to right

if at one point it cannot find any succeeding choice, it backtracks to the previous choice

Zgarb

Ok, makes sense.

you can't really flip ẹ because it's not a true relationship

Why don't you simply use c though?

Also, you actually don't need the first ẹ, zip will work on a number directly

@Poke I think it's a lot better than Slack at organizing large groups of people, so in an enterprise environment it's really nice. For just chatting, a lot of features suddenly stop being useful, so something more lightweight would be preferable.

Essentially it's like Slack, but moreso. It's even better at what Slack is good at, but all the reasons to not to use Slack are magnified.

But I don't agree with their conversion of Hueco (V system) to roping

I'd consider a 5.11 harder than a V4 for example

@cairdcoinheringaahing Cool. Do you do lead climbing? I've never gotten into it yet

caird coinheringaahing

9:17 PM

@DJMcMayhem Yeah. It's definitely more fun than top roping, but can be scary at times. TBH that's a real problem I have with some climbs

DJMcMayhem

Hardest I've done on ropes is one 5.12. On bouldering, I've done 1 V6 and one V7, but I think those were exceptions cause even V5 is really on the edge for me

So V5 is the hardest I think I've really done

caird coinheringaahing

I think it's a real shame that we don't do climbing in PE at school, it's such a great sport

@DJMcMayhem If I'm converting correctly, V6 is the hardest I've done bouldering, but I've come close to V7 a few times

DJMcMayhem

@cairdcoinheringaahing I'm sure. I've done some route-cleaning (top-roping a route someone else lead and unclipping the ropes as you go) and it's incredible how much harder it makes it. Even a relatively easy 5.9 for me becomes a serious challenge when I'm cleaning
