Are you sure that's all I need? I mean I'm used to in depth learning like theory of constructors/initialization and such.
<Andoriyu>
two arrays, one has hashes, another one integers. Need to remove all hashes where one specific key is included in the second array. Is there faster way then Array#reject?
<Kendro>
No idea if there is any need for such in Ruby.
<dodobrain>
Kendro, if you are familiar with C++ it should be easy enough to pick up just looking at the '20-min tutorial' on ruby-lang.org and then also reading the 'Ruby from another language' pages also on ruby-lang.org

vulix depends a lot on the gem; if it is pure ruby, it should work flawlessly if you adhere to good-use-practice

vulix, if you are on Windows and your machines are Linux, it will never be the same env.

umm.. rake is a shellscript right? and i have the correct one in my PATH and in it in the header it refers to the correct version of ruby too
<dodobrain>
sevenseacat, so if i'm using chruby, i should be able to simply do rake db:migrate and get the same result, right?

no

well, yes, as long as you only have one version of every gem installed

<dodobrain>
no i guess i should really know: what does 'bundle' actually do?
<dodobrain>
s/no/now
<sevenseacat>
only loads those gems which are part of your Gemfile.
Asher has joined #ruby
<sevenseacat>
so you can safely have 45 different versions of rails installed, but you'll only use the one thats in your Gemfile.
<havenwood>
dodobrain: If you want to have it work automagically you can install the rubygems-bundler gem, but you prefix `bundle exec` to use the exact gems specified in your Gemfile.lock.
<dodobrain>
i know Gemfile lists gems that are needed (along with minimum version sometimes), Gemfile.lock lists the exact versions that were installed. 'bundle install' can be used to install the gems listed in Gemfile, 'bundle update' will update the gems and if necessary update Gemfile.lock as well

why is it that it looks like the variable name itself doesn't matter, only the order in which they are received (through gets)? reiterated my previous question in a different way https://gist.github.com/Luomint/82a3e6d6f6b41e5c39de

Hounddog: what i would do since your file is dynamic is assume no machine name is passed in as an argument (causing it to process all machines defined), then in your code check for an ENV variable of your choosing that defines the machine group or machiens to put into the definition

<xxneolithicxx>
Hounddog: if you do it that way and then someone provides a machine name to vagrant as well, then it ignores all other machines you defined and only processes the action against that explicit machine

this might be more of a rails question, but I figure I'll ask here. I have a module in the lib directory. Normally I can access this module jsut fine, initialize it (set an instance variable), and call its methods. However, when I make it a delayed_job, it's like every time a job executes it's redefining my module from the module file. So then I have to initialize it every time

anyone use Arq here? is Arc 4 worth it compared to 3

Simple question: why aren't errors and exceptions that are expected to be thrown documented? e.g. http://ruby-doc.org/stdlib-1.9.3/libdoc/socket/rdoc/IPSocket.html should document that it can throw SocketError: getaddrinfo: Name or service not known. this is somewhat confusing when you come from other languages

the pickaxe guys termed the word "duck typing"... where it should not matter if it is an Array or a String or anything, as long as it would respond to a given method (in this case .size; both Array and String have this method)

siaw23 so that he can use all those method calls: ^ / %

rabbit % 5

looks like utter shit to me, but perhaps he loves it

Secnz the docs mainly. that will not teach you ruby it teaches you best practices and more advanced stuff. TWGR teaches you ruby as a language.
<Secnz>
I mainly want to learn Ruby for RoR, don't know if that's a good enough reason to do so.
<shevy>
Secnz we are losing you ... :(

you are turning into the enemies on #rubyonrails
<siaw23>

it assumes you know some ruby already but teaches more idiomattic code

idiomatic*
<vhlfd>
idiotic
<Secnz>
weaksauce: So couldn't I read it?
<shevy>
lol vhlfd
<shevy>
Secnz you really need to read less and write more. a single ruby book must be more than enough, if you need a second one then I can not believe that you know C++ already
<Secnz>
shevy: I'm used to read a lot of books that's why.

the biggest difference between ruby and say python is the philosophy. once you understood the philosophy, ruby will be trivial and consistent to itself
<weaksauce>
perhaps. if you know basic programming things and can look up stuff when you get confused
<weaksauce>
Secnz do you know how to use blocks?
<shevy>
well C++ is really complicated. have you read the old interview of matz where he said he did not like to be surprised in C++?

Does anyone know how I might go about redirecting IO from say executing bash.. so I could have a terminal in a browser? I realize that there's things I'd have to set like term -- and is there a way to deal with all the term-y kinda stuff that can happen? ie loading a text editor (nano, vi, whatever)
<FrankD>
i thought there might be a library for something like that
<jhass>
look into how the "SSH in a browser" thingies do it
