@zʏᴀʙiɴ101 why is your internet speed so volatile?

zʏᴀʙiɴ101

@uoɥʇʎPʎzɐɹC Duga is a female bot living in Code Review's main chat room, the 2nd Monitor.

uoɥʇʎPʎzɐɹC

@zʏᴀʙiɴ101 all of the assistants are female nowadays

our chatroom should have funny tags like CR

are you guys doing Project Euler? is it good?

TùxCräftîñg

uoɥʇʎPʎzɐɹC

I like how PPCG chat is just water cooler and most other site-wide chat rooms are just for support, help, or stuff related to the site

aditsu

water cooler minus the cool water

TùxCräftîñg

aditsu

do you submit code or output?

zʏᴀʙiɴ101

@aditsu output.

Because these are actually math problems that may be solved by computing.

You can do it by hand.

If you want...

Mᴀʀs Uʟᴛᴏʀ

1:28 PM

some are possible/easier by hand

aditsu

so I can solve them in CJam if I want to :)

TùxCräftîñg

Congratulations, the answer you gave to problem 1 is correct.

zʏᴀʙiɴ101

@ven ( Dennis would put in all his knowldege in golfing. ) O o .

@Phrancis I think the first few are quite brute-forcy

Sp3000

Re Tux: I'm pretty sure even CJam could do sub 15 for Q6 :P

zʏᴀʙiɴ101

@Phrancis And you, as always, would put your solution for review?

TùxCräftîñg

1:56 PM

xD

zʏᴀʙiɴ101

For code review.

aditsu

@Sp3000 I did it in 16 but I'm not really trying to golf

Phrancis

@zʏᴀʙiɴ101 I don't put all of them for review, but this one could be a decent candidate

uoɥʇʎPʎzɐɹC

Mᴀʀs Uʟᴛᴏʀ

@Fatalize i.e. Sublime Text

@MᴀʀsUʟᴛᴏʀ I said IDE, not garbage

Chat mini-challenge: given a string and an index, return the word in the string around that index.

A word is defined by the regex `(?<![A-Za-z0-9_])[A-Za-z0-9_]+(?![A-Za-z0-9_])`

zʏᴀʙiɴ101

2:04 PM

@aditsu I need 1.8 for that.

I can't run 1.8.

Leaky Nun

Should I post it in main?

zʏᴀʙiɴ101

Eclipse 2.1 has help working sets. Working sets limit the available space, so they might be used, i.e; for removal of distracting projects.

aditsu

I don't think it's necessary

Leaky Nun

(It is inspired by the feature of Windows which selects a portion of the text when double-clicked, but the specs are not exactly the same)

Fatalize

@LeakyNun needs examples

aditsu

2:05 PM

1.6 should be enough

ven

@LeakyNun running the regexp is enough :c

zʏᴀʙiɴ101

So, 2.1 expands that to the Help Center, so you can throw away some items of the help away.

Phrancis

@zʏᴀʙiɴ101 No, just IntelliJ is a much better IDE for Java than Eclipse is ;P

Leaky Nun

@Fatalize if I post it in the main then I'll add examples

@ven the regexp will return every word, instead of the word around that index

Fatalize

@LeakyNun Post it to the Sandbox first

zʏᴀʙiɴ101

2:05 PM

@Phrancis I'm sure you can't add to it.

ven

@LeakyNun ah, yes, there's a second input

Leaky Nun

@Fatalize I'm just asking if there's any duplicate and if it will be ~~a fun~~ an interesting idea

Phrancis

@zʏᴀʙiɴ101 Sure you can

zʏᴀʙiɴ101

The help working sets affect search for help and the Help Center itself.

@Phrancis How? O_O

Fatalize

@LeakyNun I'm not really the best to recognize duplicates

Sp3000

Er... I'd say float precision, but given the nature of the problem that probably doesn't matter

quartata

NetBeans doesn't perform great I'll grant you but managing builds and SVN is wayyy easier than in Eclipse

Also GUI builder

Fatalize

and way harder than in IntelliJ

aditsu

2:09 PM

eww, SVN

quartata

Also built in Glassfish

Phrancis

I think we can at least all agree that Eclipse sucks.

That's the way regexes work in Perl 6: when you match a regex, you get a Match object, that has some properties like from, to, orig, etc. (as well as means to convert to Str, Int, etc)

Leaky Nun

what about ('abc def ghi',5)?

@quartata well, "thanks". I disagree that Perl 6 sucks, though. But it's surely not best for golfing :P

That's the most I can golf it without changing the regex. I'd like to use ~~ instead of a manual .ACCEPTS:, but ~~ sets the topic, so...
