Q: Base converting with strings in bases 1 to 36 to bases 1 to 36

I'm writing a fastest-code challenge over at PPCG relating to base conversion of bases 1 to 36, and as a part of the process for writing the competition, I decided to write my own program for it. This is the code I wish to be reviewed: public class BaseConv { // Disallow instantiation p...

Aqua Tart

@VoteToClose good enough

VoteToClose

Also: what's the name of "||"?

Aqua Tart

Logical OR.

VoteToClose

That's "|", not "||".

Aqua Tart

No, | is bitwise OR.

VoteToClose

19:10

Oh.

>.>

Thanks. :D

Aqua Tart

np

VoteToClose

I read somewhere that the single bar is faster for shorter lists.

Aqua Tart

In the case of Java | actually does logical OR on booleans so there's no difference

The only difference is that || short-circuits and | doesn't

VoteToClose

Ummm... really?

Aqua Tart

Ye.

If they're integers it does bitwise.

VoteToClose

Huh. That's kinda stupid for optimization. :P

Easterly Irk

Sorry to offend lovers of ungolfy languages.

VoteToClose

kek

Aqua Tart

@VoteToClose Why?

Easterly Irk

19:15

You obviously want to optimize golfiness and speed, and they make the longer one faster? How dumb is that? :p

Martin Büttner

@VoteToClose "Bases specified must be less than 36 and greater than 2." ... less than 37 and greater than 1

Easterly Irk

^

Aqua Tart

The speed difference is negligible in most cases.

Easterly Irk

BUT I WANT FAST AND GOLFY PLS HALP ME WITH THAT JAVA

VoteToClose

@AquaTart Because logical ORs make branch instructions, which can be more computationally complex, and bitwise ORs do not, they simply calculate. So, for instructions where you're less certain to jump/certain of conditionals, you want to use |, not || because it's faster. :P

Aqua Tart

19:16

It's more of a matter of if you want it to short-circuit or not

VoteToClose

@MartinBüttner Oh, crap, you're right. D:

Thanks.

Aqua Tart

@VoteToClose Logical OR doesn't branch, the if does.

At least I don't think a logical OR would need to branch. I suppose it depends on your flavor of assembly.

VoteToClose

Hold on, I'm checking. :P

Scroll down a bit on this page; if it works the same way in Java, then it branches.

Aqua Tart

Oh, you mean because of the short-circuiting.

OK, fair enough.

The performance loss is tiny.

Easterly Irk

But it matters to OCD people ~~like me~~.

Aqua Tart

19:23

eh

It wouldn't make a whole lot of sense to have | be bitwise with booleans in Java anyways since booleans aren't technically considered numbers

What is LINQ anyway?

mınxomaτ

Language Integrated Query

Language Integrated Query (LINQ, pronounced "link") is a Microsoft .NET Framework component that adds native data querying capabilities to .NET languages, although ports exist for Java, PHP, JavaScript and ActionScript. LINQ extends the language by the addition of query expressions, which are akin to SQL statements, and can be used to conveniently extract and process data from arrays, enumerable classes, XML documents, relational databases, and third-party data sources. Other uses, which utilize query expressions as a general framework for readably composing arbitrary computations, include the...

El'endia Starman

huh, cool

mınxomaτ

It's really weird at first, because it kinda breaks the language paradigm, but once you know what you're doing you wish everything had LINQ ;)

Alex A.

20:11

Can confirm, LINQ is really nice.

mınxomaτ

linqjs is probably not that popular because JS programmers are the exact opposite of C# programmers.

Alex A.

Because C# programmers put time and effort into their code to make it good and JS programmers just throw crap at the wall and see what sticks? :P

The Hitchhiker's Guide to the Galaxy

The Hitchhiker's Guide to the Galaxy (sometimes referred to as HG2G, HHGTTG or H2G2) is a comedy science fiction series created by Douglas Adams. Originally a radio comedy broadcast on BBC Radio 4 in 1978, it was later adapted to other formats, including stage shows, novels, comic book adaptations, a 1981 TV series, a 1984 computer game, and 2005 feature film. The Hitchhiker's Guide to the Galaxy has become an international multi-media phenomenon. The novels are the most widely distributed, having been translated into more than 30 languages by 2005. The broad narrative follows the misadventures...
