@LegionMammal978 well, yeah, this was the general solution for use in stack-based programs

This page I'm looking at implements a countdown by having a GIF with 40 or so frames advancing once per second (with e.g. '7 hours 5 minutes 33 seconds') and reloading the entire page every 10 seconds or so.

00:05

In fact, borrowing some of your code, I can shorten mine to ||0e00e--|-ee

ETHproductions

@feersum Um... that's one way to do it

Conor O'Brien

@feersum which website?

@Riker Reccomendation: don't forget iPad in Hawaii

Conor O'Brien

@LegionMammal978 that's pretty cool

Riker

@Downgoat pennsylvania this time ;p

ETHproductions

Is this an acceptable coding style:

if (blah) {
  doStuff();
} else
if (blah2) {
  doStuff2();
} else
...

Qwerp-Derp

@ETHproductions Eugh that looks pretty bad

LegionMammal978

@ConorO'Brien A comparison of the meanings of the two programs:

*||0e00e--|-ee#          = exp(exp(ln(ln(x))-ln(exp(0)-(0-exp(0)))))
*0e00e--|0~-e|~||0~--ee# = exp(exp(ln(exp(0-ln(exp(0)-(0-exp(0)))))-(0-ln(ln(x)))))

ETHproductions

Yeah, but it makes chaining conditionals easier, since you can just copy-paste whole lines

Qwerp-Derp

You can still do that normally, you just have to paste it after the else

ETHproductions

Oh, well I guess in my normal coding style, e.g.

if (blah) {
  doStuff();
} else if (blah2) {
  doStuff2();
} else ...

you can just copy-paste } else if (blah2) { and the following lines

But I like my other idea because it lines all the ifs up at the left

Qwerp-Derp

00:15

I'm not sure how proposals work, but if I have a system that extends on two or more of the previous systems, can I post my own separate proposal, or do I have to just comment it?

I have a proposal for representing repeating decimals in unary, BTW

Conor O'Brien

if (x) {

}

else if (y) {

}

@LegionMammal978 mm nice!

@Qwerp-Derp I think you can post it if you want, as long as it's not almost completely the same as one of the other answers

Infinite recursion isn't hard to detect in most scenarios. It's determining whether or not it will loop infinitely in all scenarios that's the issue

Q: Storing an array of Integers to WOM

Very few, if any, programs or applications have utilised the proposed spec for WOM which was initially thought up in the early 1970s as a polar opposite to ROM, so your task is to take a dataset of n Integers and simulate storing it to a WOM schema as a proof of concept. Your array must contain ...

should we make it in blue corner or something

unsigned int *buf = calloc(self->size, sizeof(unsigned int));

self->size is also an uint, set to 5 currently

Kritixi Lithos

12:54

I'll just assume it is okay as it is because of the hello world answer in APL

Bernardo Meurer

I want buf to have space for 5 self->size unsigned ints

Dada

this looks fine, depending on the value self->size actually holds

SIGSEGV

I have an awesome idea

Bernardo Meurer

@Dada self->size is always between 4 and 11

Okay, I follow that with a series of manipulations on the arrays, the code is fairly clear I think

    for (unsigned int i = 0; i < self->size; ++i) {
        if (direction == UP || direction == DOWN) {
            self->getCol(self, rowcol, i);
        } else self->getRow(self, rowcol, i);

        for (int j = start; j != end; j += delta) {
            if (rowcol[j] == EMPTY) continue;
            if (buf[idx] == EMPTY) buf[idx] = rowcol[i];
            else if (rowcol[i] == buf[idx]) {
                ++buf[idx];
                self->score += 1 << buf[idx];
            } else {
