The Nineteenth Byte

For some reason, I'm certain that Valorum used to have a very active account on SciFi, had it deleted for some reason, then rejoined as Valorum. Yet I just spent 30 minutes meta diving on SFF and can't find why I believe that :/

Rand al'Thor

Huh?

There was a much older user on SFF called Richard, but no relation to the high-rep Richard who became Valorum.

The trick is that {ddddddddd} can be replaced with {{d}i}.

I'd be very interested if this is true, but it's not something I've heard about in 7 years on SFF including 5 as a mod.

@Randal'Thor Given that users/30/ looks to be still around, I genuinely have no idea why I had that number in my head, and I guess I must have gone of comments with @Richard replies and got them mixed up with Valorum

Q: Consecutive Distance Rating

Consecutive Distance Rating We'll call the consecutive distance rating of an integer sequence the sum of the distances between consecutive integers. Consider 2 9 3 6 8 1. 2 9 3 6 8 1 <----5----> <-2-> <--3--> \$2\$ and \$1\$ are consecutive integers, and their distance apart in the sequence is...

caird coinheringaahing

I know that Valorum keeps their SFF account hidden from their other network accounts, which may have contributed to my belief, but that's weird. I think I'll have to do some more diving when I'm not on mobile

that feeling you get when you suddenly realise you can find the difference between the two elements in an array by converting it from base -1

StackMeter

@Neil wdym

Neil

@StackMeter let's say I have an array u = [x, y] and I want to compute y - x, I used to do Minus(Pop(u), Pop(u)) but now I can do Base(Negate(1), u) instead. This already saves a byte, plus I don't need to assign to u if this is the only remaining use.
