Thanks

Destructible Watermelon

@MartinEnder done!

much better :)

betseg

what are push and pop i don't know and see everywhere plz explain

Steven H.

9:06 AM

Push and pop are stack operations: "put new value on top of stack" and "take top value off and return"

betseg

@StevenH. What iz stack i see that everywhere too but I dunno wat iz

Steven H.

Think of a stack of books

Except each book is a data value

(I'm assuming here your confusion is legitimate, but honestly I'm too tired to tell one way or the other)

betseg

@StevenH. Like a c array? Or linked list?

Steven H.

Like a linked list except you only look at the first value at any given time

the "top" of the stack is the head of the list

betseg

K thx

devnull-as-a-service.com lol

Steven H.

pop returns the head and sets the head to head.next, push sets the head to a new node with node.next=head

TùxCräftîñg

this core war will never end

betseg

@StevenH. oooh i get it now

TùxCräftîñg

omg it ended

Steven H.

There's also peek which just returns head.value

@TùxCräftîñg yay, you win you!

pop() { return *(sp++); } push(v) { *--sp = v; }

where sp is a pointer to the top of the stack

9:17 AM

Although it's a matter of personal preference as to whether you use ++ or -- for pop (always the opposite for push), personally I like pop(){ return *(sp--);}

TùxCräftîñg

but it should work with wine

@DestructibleWatermelon Download the DOS 386+ version and DOSBox.

Destructible Watermelon

thanks d00d

already have dosbox too

@StevenH. -- for push and ++ for pop is a 'standard'

every CPU architecture use this for stack management

Steven H.

There's some microcontrollers that stack manage in the reversed manner

Don't repeat yourself

In software engineering, don't repeat yourself (DRY) is a principle of software development, aimed at reducing repetition of information of all kinds, especially useful in multi-tier architectures. The DRY principle is stated as "Every piece of knowledge must have a single, unambiguous, authoritative representation within a system". The principle has been formulated by Andy Hunt and Dave Thomas in their book The Pragmatic Programmer. They apply it quite broadly to include "database schemas, test plans, the build system, even documentation." When the DRY principle is applied successfully, a ...

There's a version written in Python but it's horrible at recursion and doesn't have the majority of things implemented, so I figure before I continue breaking the recursion limit forevermore I should move to the proper language to write a functional golfing language in.

I'm more familiar with Racket, and don't want to learn all of the ins and outs of basic Lisp to use it as effectively as I do Racket. I'm planning to format, transpile, and then eval; that should be a little bit simpler than building from ground up

Is your number happy or melancholic? A famous stand-up mathematician Matt Parker invented the procedure of happification: you pick a number, square the digits and take the sum.

> The # symbol is commonly called the pound sign, number sign and more recently the hashtag. It is called the pound sign because the symbol comes from the abbreviation for weight, lb, or “libra pondo” literally “pound by weight” in Latin. When writing lb, it was not uncommon for scribes to cross the letters across the top with a line across the top, like a t. See the example below.

Q: Does codegolf involve only code size?

I'd like to know if codegolf does allow other kinds of challenges, like memory-size related ones (Given a structure, try to use the least amount of bits to store the same information) and so on. I don't know if this kind of challenge fits codegolfing or not.

@Sp3000 The downvoter exaplained the vote, so it's fair enough. It was downvoted because the voter thought it was boring.

Even if they happen at similar times it's not definite that it was the same person. I often comment on downvoted posts shortly after the downvote.

Stewie Griffin

@trichoplax True, and so do I. "I guess the downvote was because xxx". In this case I'm fairly sure it's the same user though... Not that it matters...

trichoplax

Fair enough.

Stewie Griffin

11:21 AM

Even if it was someone else, I guess the explanation is the same. :)

trichoplax

It's also only one user, so I'd read more into the lack of upvotes than the solitary downvote

Stewie Griffin

Therefore, "I'll leave it there a few hours, to see if someone wants to give it a go". :)
