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...

java performance parsing

@VoteToClose good enough

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

Logical OR.

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

No, | is bitwise OR.

7:10 PM

Oh.

>.>

Thanks. :D

np

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

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

Ummm... really?

Ye.

If they're integers it does bitwise.

7:12 PM

@CᴏɴᴏʀO'Bʀɪᴇɴ can you see my fork and patch for oration? I added a couple useful things.

docs.oracle.com/javase/specs/jls/se7/html/…

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

ಠ_ಠ

Sorry to offend lovers of ungolfy languages.

kek

@VoteToClose Why?

7:15 PM

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

^

The speed difference is negligible in most cases.

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

@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

7:16 PM

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

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

Thanks.

@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.

Hold on, I'm checking. :P

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

Oh, you mean because of the short-circuiting.

OK, fair enough.

The performance loss is tiny.

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

7:23 PM

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

TIL: Don't run Ʀ in jolf.

Not fun.

?

github.com/ConorOBrien-Foxx/Jolf/blob/master/src/jolf.js#L3392

Read that line of code.

It redirects to conorobrien-foxx.github.io/Jolf/jolf.html.

Don't click that link.

It redirects to https://www.youtube.com/watch?v=dQw4w9WgXcQ.

Which is the link that you are probably thinking it is.

7:28 PM

@AandN did you actually run it? lol

:(

@VoteToClose i don't care how wow it is.

@AandN sorry

Cᴏɴᴏʀ O'Bʀɪᴇɴ

@EasterlyIrk I'll take a look right now

AND WTF

kek

Hahahah

Cᴏɴᴏʀ O'Bʀɪᴇɴ

7:29 PM

Oh.

@CᴏɴᴏʀO'Bʀɪᴇɴ I added you as a collab on Vitsy, btw.

Yeah, 'oh'.

ಠ_ಠ

Cᴏɴᴏʀ O'Bʀɪᴇɴ

@VoteToClose \o/

@EasterlyIrk :3 Want to see some Jolf code?

@VoteToClose ಠ_ಠ

@CᴏɴᴏʀO'Bʀɪᴇɴ maybe

does it have "\u01a6" in it?

Cᴏɴᴏʀ O'Bʀɪᴇɴ

maybe

Will you press run unconditionally?

7:30 PM

yes

@EasterlyIrk He was interested in making a JS version of VitsySafe. ¯\_(ツ)_/¯

Unless the button breaks.

Cᴏɴᴏʀ O'Bʀɪᴇɴ

@EasterlyIrk >_>

@VoteToClose It doesn't have that command, right? Or any equivilent?

Cᴏɴᴏʀ O'Bʀɪᴇɴ

@VoteToClose Yup! I've got a general idea in my head as how to do it, but no actual code has been done.

7:31 PM

@CᴏɴᴏʀO'Bʀɪᴇɴ fine whatever

@CᴏɴᴏʀO'Bʀɪᴇɴ :D

@EasterlyIrk No. And it never will.

Good.

is it that rickroll code again?

Cᴏɴᴏʀ O'Bʀɪᴇɴ

Does anyone know a good JS collab site?

Or I will call it purse dog.

@Maltysen yes

@CᴏɴᴏʀO'Bʀɪᴇɴ coderpad?

For short bits only though I think,

7:31 PM

codepen

coderpad.io

codepen.io

That is even better, thanks @Maltysen.

Cᴏɴᴏʀ O'Bʀɪᴇɴ

Does either have real-time editing?

Yes,

Cᴏɴᴏʀ O'Bʀɪᴇɴ

coolio

Go here:

codepen.io/anon/pen/zqYMXy

try it, does it work?

Cᴏɴᴏʀ O'Bʀɪᴇɴ

7:34 PM

It seems to be working.

Can more than one person work on it at once?

Do you see me editing though?

Cᴏɴᴏʀ O'Bʀɪᴇɴ

I don't think so?

no

So not real time.

:(

codeshare is though

but not html+css+js

7:35 PM

Okay, try here:coderpad.io/9EHCJWH9

Cᴏɴᴏʀ O'Bʀɪᴇɴ

@RikerW I have no pull requests

amint

Try now.

Cᴏɴᴏʀ O'Bʀɪᴇɴ

Got it!

Okay, cool.

Cᴏɴᴏʀ O'Bʀɪᴇɴ

You can't evaluate JS code in codeshare

7:38 PM

NOW CODE WITH US on the coderpad one

Cᴏɴᴏʀ O'Bʀɪᴇɴ

@VoteToClose join us in the coderapd

YES WE ARE SCREWING AROUN WITH NO GOAL

@CᴏɴᴏʀO'Bʀɪᴇɴ so what are we doing

Nothing, but supposedly vitsy

Cᴏɴᴏʀ O'Bʀɪᴇɴ

I'm teaching VTC JS and writing a JS vitsy interpreter

7:47 PM

VTC doesn't know JS? o_O?

SO in a nutshell.

rofl

jQuery is missing

Hahaha

Yes absolutely

Also functional programming

Isn't LINQ functional programming?

8:04 PM

@flawr Has science gone to far?

Disappointing. It's got ToInfinity, but not ToInfinityAndBeyond.

El'endia Starman

What is LINQ anyway?

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

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 ;)

8:11 PM

Can confirm, LINQ is really nice.

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

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

crap and jQuery

LegionMammal978

Phew

Just finished setting up legionmammal978.github.io/post

Uses no jQuery

Or anything serverside

Pure JavaScript+HTML5

> github.io

> nothing serverside

no shit :D

LegionMammal978

8:17 PM

No code serverside, that is

@AlexA. Good analogy.

:D Thank you

@LegionMammal978 So, what is the use case here?

No good way to put a POST request in a link

And I couldn't bother setting up 34 JSFiddles

@AlexA. But what if it's a C# programmer writing JS?

They temporarily transform into a JS programmer.

8:22 PM

@LegionMammal978 The original parsing (just using "split") is not very robust though. Here's an example that catches most edge cases.

poof

LegionMammal978

@AlexA. Now that I think about it, I did act like a JS programmer while I was writing that...

:P

LegionMammal978

Several forced pushes for testing

New website design finished! Any feedback?

8:25 PM

The figlet is unreadable

LegionMammal978

Are there supposed to be links?

@AlexA. yeah

@LegionMammal978 yes

What is HHGTTG

LegionMammal978

I don't see any

8:26 PM

@AlexA. the best book you'll ever read

Is it Nethack the novel?

LegionMammal978

I recognized it immediately

@AlexA. hahaha

@LegionMammal978 The three things at the top are links, and there are two in the third paragraph. You don't see them? -_-

@AlexA. :( Maybe I'll use a different font

@Doorknob You play the viola?

LegionMammal978

"Click the links right under my logo to find more stuff."

8:27 PM

@flawr yeah

@LegionMammal978 the "Portfolio • Blog • Contact" are links

LegionMammal978

@mınxomaτ Then their fault for clicking the link :p

Oh I thought it was talking about the figlet

For i3bang, if you're proud that airblader thought it was cool, you should link to who airblader is.

@LegionMammal978 the "Portfolio • Blog • Contact" under the logo are links

LegionMammal978

I know, but I thought the figlet was the logo

It was unclear

@LegionMammal978 No it wasnt

8:29 PM

@AlexA. airblader is a prominent member of the i3 community. Anyone who's done anything at all with i3 would recognize his name :P I guess I could link to the message though

El'endia Starman

> I also moderate Stack Exchange

@Doorknob Cool! I always liked violists over violinists, they are usually less pretentious.

El'endia Starman

*two Stack Exchange sites

-1 not as golfy :P

@Doorknob I would. If an employer or someone is reading that, that comment would mean very little to them without being able to find out who airblader is.

El'endia Starman

8:30 PM

-1 WRONG :P

@Doorknob +1 for HHGTTG

LegionMammal978

But look at the source for my tool

Is it not golfy enough?

Martin Büttner

@Doorknob 3/10 not enough Ostrich

@Doorknob Then your site would be HiIamDoorknobAKAKeyboardFireAndAProgrammerAndASEModKThxBye!

@AquaTart If you like it too then it must be about Nethack

8:31 PM

@LegionMammal978 651 bytes, nice :P

6/10 insufficiently phallic

@MartinBüttner hey... that's Alex's job :P

Do you actually not know what it is or are you just joking?

LegionMammal978

@Doorknob I'd remove the newline, but POSIX, so yeah

What is HHGTTG

Martin Büttner

8:32 PM

hitchhiker's guide to the galaxy

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...

Also @Doorknob I would specify what SE sites you are mod on

@AquaTart I'm trying to keep the text on the homepage as short as possible. It has a link to my accounts list anyway

OHHHHHHH

Of course I know that book

I never finished reading it though :I

LegionMammal978

Am I the only one here who habitually adds needed {{cn}}s to Wikipedia pages as I read them?

8:34 PM

@AlexA. how much of it have you read?

@LegionMammal978 Unfortunately there is no such thing in the german wikipedia.

@LegionMammal978 yes [citation-needed]

@Doorknob Your website is really cool. I think it showcases your accomplishments and skills well. It flows nicely, it's easy to access whatever information one might want. Very nice work.

@Doorknob First couple chapters. My girlfriend got it for me for my 18th birthday. So it's been a long time.

@AlexA. thanks :)

oh god chaos

@AlexA. Yas.

Martin Büttner

8:37 PM

Now we know that Alex is 18 + a long time years old.

I though he was 6? o_O?

Can a long time be negative???

@AlexA. How is it even possible to only read "a few chapters" of it

LegionMammal978

^

^

@MartinBüttner Depending on your perspective, I suppose 7 years is a long time.

@AquaTart I'm really bad at finishing books.

8:39 PM

@AlexA. is 25??? o_O? I actually though you were liek 40.

@EasterlyIrk why would you think that

Martin Büttner

^

IDK

Martin Büttner

(no offence xD)

Uh no... I've said my age multiple times in here, and it's on my SE network profile. :P

8:40 PM

I mean, he has said multiple times he's working on a master's

Bc I don't look at profiles.

Sorry @AlexA..

@MartinBüttner I can't believe you wouldn't think I'm 40. Wow, such offense. Very taken.

lol

@AlexA. *much taken

@EasterlyIrk Why are you sorry?

@AquaTart amaze

Martin Büttner

8:41 PM

wow.

The idea behind doge grammar is that the modifiers can't modify the words

BC I am confused about everything including why I can type with a mouse.

Very could modify taken ("He was very taken with...")

> The idea behind doge grammar

...

how take screenshot with mouse???

8:42 PM

Just educating you

ooh brb

My keyboard is not working approiately.

It keeps thinking that the command key is stuck down, so I can't type C or A with it.

But clearly you can type p and r, so you have no excuse for misspelling "appropriately."

Help Jason Format his JSON code-golf Jason has a big JSON but it's unreadable, so he needs to prettify it. Your code will need to be short because unformatted JSON is short. Examples [1,2,3] [1, 2, 3] {"a":1,"b":4} { "a": 1, "b": 4 } "foo" "foo" 56 56 {"a":[{"b":1,"c":"foo"},{"d":[2,3...

Martin Büttner

@TogaDown as Peter suggested the other day, I think your challenges would generally be improved by putting the spec before the examples

@Doorknob mini or slant

Martin Büttner

9:02 PM

@TogaDown if \" escapes need to be supported, please cover them in the test cases

also, do we need to support {} and []? if so, test case please :)

@Doorknob CR hates PPCG comments

also, please remove "Your code will need to be short because unformatted JSON is short."

Martin Büttner

^

would also be good to have a test case with an array that contains only strings

also an array that contains both integers and strings but nothing else

to answer your actual question, "no but it's getting there". ;)

@TogaDown are spaces allowed after commas if the array is broken over multiple lines?

9:23 PM

Oh hey, it's @edc65! Long time no see. :)

Hey @edc65

People always say you should parse HTML with regex. But has anyone tried parsing regex with HTML?

@edc65 sorry that was just a comment on why I miscalculated the byte saving on my suggestion

@AlexA. Yes actually.

I parsed regex with html with a js regex.

JavaScript != HTML

9:28 PM

@MartinBüttner I'm here

what kind of changes?

Martin Büttner

big changes :P

let me push them, then I'll explain

"you should parse HTML with regex" - Alex A.

@AlexA. It was impolemented with a <script> tag and a webpage.

@trichoplax alex-is-cthulu-summoner

Martin Büttner

@randomra okay, the master branch has the changes now

let's discuss this in the esolangs room

9:41 PM

@LegionMammal978 Oh, damn, can I help you on VitsyJS?

You've done a lot. :O

@AlexA. not actually a real comment

@AquaTart Yes it is

Last I checked hitting the "1 hour ago" button doesn't take me to timeanddate.com/worldclock/uk/cardiff

It takes me to the comment.

But then again I'm just a glider what do I know

It's a real comment in the sense that it is a comment that has been made.

Cᴏɴᴏʀ O'Bʀɪᴇɴ

@VoteToClose >_>

9:49 PM

I only saw him. xD Sorry.

@AlexA. That seems to imply that comments that have not been made are unreal?

Cᴏɴᴏʀ O'Bʀɪᴇɴ

No prob XD

@flawr Comments are actually small beings that live on the surface of the moon.

@AlexA. TIL

Cᴏɴᴏʀ O'Bʀɪᴇɴ
