00:04 <bradland> StarCraft. Confidence interval, 99%.

00:04 <bradland> (I made that up)

00:05 <Dolphi> What league do you play in?

00:05 <Dolphi> I'm high gold, but I haven't played for about 2 weeks now.

00:05 shime has quit [Ping timeout: 252 seconds]

00:06 <bradland> haven't played starcraft in about 417 weeks.

00:06 <bradland> approximately

00:06 <Dolphi> bradland: Haha, nice.

00:06 <Dolphi> How have you been man? I've been working on HTML & CSS with Codecademy.

00:07 <Dolphi> Started my first web project. It is a little gaming blog for myself. I'll probably never host it, but I'm having fun building it at least.

00:07 ta has joined #ruby

00:08 <bradland> nice! i'm actually going through the codeacademy ruby class right now

00:08 <bradland> so i know what the heck people are asking about when they come here

00:08 <bradland> pro-tip

00:08 <bradland> put everything you do on github

00:09 <bradland> it won't always be nice, and you won't always learn something, but occassionally, you'll get that gem of knowledge that you'd have never found on your own

00:09 <Dolphi> The ruby course won't work on my laptop for some reason, and I'm not sure why. Python as well. All others work fine, I believe.

00:09 <bradland> strange

00:09 <bradland> what browser?

00:09 apxm has joined #ruby

00:09 <Dolphi> Firefox, of course.

00:09 <bradland> bizarre. i'd expect it to work in firefox.

00:10 <bradland> Windows?

00:10 <Dolphi> I've also tried on Chrome.

00:10 <Dolphi> Yes, Windows.

00:10 <Dolphi> The only thing that I can really think of is maybe my web security won't let it load properly or something?

00:11 <Dolphi> I use Kaspersky Internet Security.

00:11 <bradland> that's quite possible

00:11 <bradland> it's JS heavy, i'm sure

00:11 <bradland> if you're going to do web dev, might as well start learning linux

01:26 <pontiki> grand idea. :_

01:27 <pontiki> :) i meant

01:27 <Dolphi> pontiki: I partially feel like that is sarcasm, haha.

01:27 <pontiki> Dolphi: are you going to be learning it's UI as well, or just as a server?

01:27 <pontiki> it wasn't meant as sarcasm in any way

01:28 mrmargolis has quit [Remote host closed the connection]

01:28 francisfish has quit [Ping timeout: 276 seconds]

01:28 <Dolphi> I didn't know that it had two parts to learn.

01:28 freerobby has joined #ruby

01:28 <Dolphi> I suppose both then.

01:28 <pontiki> well, there's a GUI that runs like a desktop

01:28 <pontiki> and it's a bit of a different experience than OS/X or Windows

01:29 dc_ has quit [Remote host closed the connection]

01:29 <pontiki> otherwise one can strictly stay with the command line experience

01:29 cajone has joined #ruby

01:29 <Dolphi> Which do you use?

01:30 <Dolphi> Doing everything from the command line seems like a lot of work.

01:30 <pontiki> just the command line, but I am probably a reprobate as well in that I don't really like GUIs

01:30 <pontiki> even on OS/X i do practically everything from the command line

01:30 dfinninger has joined #ruby

01:30 taiansu has joined #ruby

01:31 <Dolphi> But I keep hearing good things about Linux, and bradland (I believe he was the first person that I ever talked to on IRC :') ) suggested it to me, so I figured I would give it a try.

01:31 <pontiki> i do think it's a great idea

01:31 <Dolphi> What advantage does that have?

01:31 <pontiki> i do all my development work that way

01:31 shime_ has quit [Remote host closed the connection]

01:31 <pontiki> it's the same environment i typically deploy to

01:32 <pontiki> i have *never* , in fact, deployed to anything but linux-based systems

01:32 <Dolphi> Really?

01:32 it0a has quit [Quit: WeeChat 1.1]

01:32 * pontiki nods

01:32 <Dolphi> I actually haven't even heard of Linux until about a month ago.

01:32 <pontiki> never to a windows server, never to an OS/X server, never to a *BSD server

01:32 <sevenseacat> i deployed to an IIS system once. that was painful.

01:32 <Dolphi> (When I first started reading up about programming)

01:32 shime has joined #ruby

01:33 <Dolphi> What exactly is a server?

01:33 <xxneolithicxx> Linux is a lot easier to setup programming environments in as depending on the language it might already be there by default

01:33 davidhq has quit [Quit: My MacBook Pro has gone to sleep. ZZZzzz…]

01:34 ta has joined #ruby

01:34 <pontiki> Dolphi: there are a few definitions. 1) a machine, real or virtual, that runs applications but does not have a dedicated graphical display

01:34 pdoherty has joined #ruby

01:34 <Dolphi> As in like a web hosting server?

01:34 <pontiki> the application or application resources are also referred to as servers: web server, file server, database server

01:34 <pontiki> yes

01:35 taiansu has quit [Ping timeout: 264 seconds]

01:35 <Dolphi> Ah, I understand. So a file and database server could be used in lets say, an office environment? You could link local computers to the server to share data quickly?

01:36 <Dolphi> I'm trying to wrap my head around all of this.

01:36 <pontiki> when you hear people say "the cloud", that's generally referring to machines serving files, running applications and services, from somewhere else

01:36 <pontiki> Dolphi: i've been doing this sort of thing for decades, so it's sometimes hard for me to figure out what and how to explain

01:36 Adran has quit [Remote host closed the connection]

01:37 <Dolphi> It's alright, I'll be in your shoes one day, hopefully. For now I'm just a greenhorn trying to learn what I can from the veterans. :)

01:37 <pontiki> it's all good

01:38 <pontiki> this is the most fun work in the world, i think

01:38 <xxneolithicxx> another way to look at it is that a server is meant to offer services a user or a software service offering (website, ftp server, email) uses vs a typical desktop environment is GUI based and meant for end users to work on

01:38 <blizzy> so, I'm trying to use RestClient, however I get this error: 301 Moved Permanently (RestClient::MovedPermanently).

01:40 <xxneolithicxx> then what pontiki said

01:40 fgo has joined #ruby

01:40 <blizzy> it's not a redirect

01:40 <xxneolithicxx> it may have an extra option to explicitly allow redirects if one is provided

01:41 <pontiki> a 301 is a redirect

03:58 <shellox> do you see the lines under products << [] ?

04:03 <scottstamp> I'm not sure if what you're doing adds any performance overhead, but there's a built in for that already, you can just do csv_object.append products

06:38 <centrx> superrorc, The error message you got is because that's now how you do multi-line strings, use heredoc syntax: http://en.wikibooks.org/wiki/Ruby_Programming/Here_documents

06:38 <centrx> *not how you do multi-line strings

06:38 <centrx> actually I'm wrong, you can do multi-line strings that way

06:38 <centrx> but you have quotation marks " in the string, which are the same quotation marks you are using outside of the string

06:39 <centrx> The cleanest way to do it is with the heredocs

06:39 asteros has quit [Quit: asteros]

06:39 <centrx> You could also replace the enclosing double quotations marks ", with single quotes ', so that it does not conflict with the double quotation marks in the string

06:45 <Xeago_> Anyone using aws ec2? Is there something better than e-mail notifications for instance notifications?

06:45 <ips|malc> how can i use that variable in my current script? i tried require 'foo' but i still can't access @test_json

06:47 <ips|malc> how can i use that variable in my current script? i tried require 'foo' but i still can't access @test_json

06:47 <ips|malc> argh, sry for double paste

08:00 <Xeago_> the value of #split(separator) should be the opposite of #join(separator)

08:00 JDiPierro has quit [Ping timeout: 272 seconds]

08:01 <Xeago_> such that when applying these functions in succession it should give back the original

08:01 oo_ has joined #ruby

08:01 <Xeago_> it is also irrelevant of the order: i.e. S(J(x)) is the same as J(S(X))

08:01 josephndenton has joined #ruby

08:01 dc_ has joined #ruby

08:01 dc_ has quit [Remote host closed the connection]

08:02 <Xeago_> where S and J denote functions applying a #split(separator) and #join(separator) respectively

08:02 <MrSamuel> Xeago_, sure that makes sense, but it doesn't match up with reality, i.e. "x".split('.') gives ['x'] and ['x'].join('.') gives 'x', which is exactly the same as if it was just whitespace

08:02 bronson has joined #ruby

08:02 <MrSamuel> i.e. "".split('.') -> [''] and [''].join('.') gives '' which is absolutely valid

08:03 dc_ has joined #ruby

09:14 <ferr> Hey, I need some advices. I need integrational tests to be structured: to configure app through UI, wait for some time until changes are applied, check if changes are applied and everything works. It has to be done by choosing tests order and skipping tests if configuration fails. What any of you would recommend? Rspec vs cucumber or any other suggestions?

10:16 <arup_r> What's the logic?

10:20 <arup_r> >> a = [1,2,3,4,5,1,2,3,1,2,3,4] ; p a.slice_when {|i, j| i+1 != j }

10:20 <arup_r> http://ruby-doc.org/core-2.2.0/Enumerable.html#method-i-slice_when

10:20 <workmad3> arup_r: or just .slice_when {|_,j| j == 1}

10:21 <workmad3> but yeah... slice_when seems like the way to go (thanks arup_r, I'd not noticed that method before :) )

10:21 terlar has quit [Quit: WeeChat 1.1]

10:21 <norc> arup_r: Wow that is neat. Is slice_when relatively new?

10:23 teddyp1cker has quit [Read error: Connection reset by peer]

10:23 <norc> arup_r: I mean, slice_when seems really really useful for lots of things Im doing right now

10:23 <workmad3> p [1,2,3,4,5,1,2,3,1,2,3,4].slice_before(1).to_a

10:23 <workmad3> >> p [1,2,3,4,5,1,2,3,1,2,3,4].slice_before(1).to_a

10:23 <eval-in_> workmad3 => [[1, 2, 3, 4, 5], [1, 2, 3], [1, 2, 3, 4]] ... (https://eval.in/244554)

10:23 <workmad3> arup_r: there's slice_before too ;)

10:24 <norc> workmad3: I told him to split whenever the sequence resets

10:24 <norc> So his solution was spot on

10:24 <norc> ÖP

10:24 <norc> :p

10:24 <arup_r> workmad3: Will now be chewing those methods

10:24 <workmad3> norc: you then said 'when it goes back to 1'

10:24 <workmad3> norc: so slice_before(1) is more elegant ;)

10:24 <norc> workmad3: Either way it is a solution :)

10:25 <norc> Now I just need to implement this method in ruby 2.0 somehow :D

13:53 <shevy> I dont have to remember anything when I use []

13:54 <shevy> another advantage is that [] is shorter there

13:54 <shevy> :-)

13:54 <Rylee> [] is a very stylistically Ruby construct

13:54 <waxjar> my worry is that you have to do a lot of output checking, because it could return a boolean, a String or an Array.

13:55 <Rylee> you already have to handle the modes separately in every IRC lib and IRC impl ever

Depended on a group or can you do pretty good stuff alone? I would like a realistic answer and not because you love Ruby :D

14:49 <kl___> thing I don't like about the Ruby community: it doesn't have a great interest in supporting dependency injection containers (at least we have Dim from the late Jim Weirich) or AOP

15:11 <workmad3> ruby isn't even a primarily web-focussed language... it's more general purpose than PHP... as such, the framework isn't just about trying to impose a structure on scripts that will just-about hang together and work without a framework... it's there to actually provide the services from HTTP request up to application level

15:12 <workmad3> bzeu: if you went entirely without a framework in ruby or in python, you'd be basically working from the CGI library in the standard library (or even implementing an HTTP server using the socket library)

20:14 <jhass> so, first of all, return is a keyword, not a method, so writing #return makes not much sense, since we use Object#method to refer to instance methods of a class

20:15 <znst> yes

20:16 <jhass> return immediately returns to the method call, providing the passed argument as return value

21:21 <omosoj> this stuff is fascinating :))

21:23 <vandemar> this is probably a dumb question but is there a nice way to rewrite if (var = expression) { do stuff with var } to a block without assignment first? Like, the regex match idiom /pattern/.match("haystack") {|matchdata| do stuff } but I want something more generic, like compute_result().if {|val_from_compute_result| do stuff }. Do I have to monkey patch all objects in the system to get this, or is t

21:23 <vandemar> here an existing way that's as nice?

23:17 <Salatfreak> Hello Rubyers! Is it still a good Idea to read "Learning Ruby" from 2007 for a ruby beginner? Are there in-depth online resources worth reading? Any suggestions?

23:19 <seanmarcia> Salatfreak I always recommend Learn to Program by Chris Pine as a first book. If you have a programming background and just want to pick up Ruby style, Pine's book might be a little basic and you should probably start with Eloquent Ruby by Russ Olsen.

23:35 <Salatfreak> seanmarcia: Hm, I think I would start with the Olsen book. But unfortunatelly it's not in my university's library and I don't really want to pay 30$ for it... Are there equally good books? I already learned some other languages and I would mainly wan't to learn to learn rails afterwards. Are there good books explaining both at once maybe?
