I'm having trouble installing recent versions of Ruby onto my OSX computer. I tried using the RVM, but it somehow managed to mess up whatever version I was using at the time. What's the most newbie-friendly recommended way to install Ruby, Rails, and whatever?

 Okay, well, I went with Sublime. I understand that CMD-B does Build, but how do I get it so that I can input stuff, like for gets? edit: Also, what does Ruby do besides Rails? I'm not necessarily interested in web development or maintaining servers, so any other things it can do (i.e. miniature OSX applications, small games, GUIs) I'd like to hear about.

tldr+warning: rails noob(?) not sure what I know, what to do next. I'm trying to figure out where my Rails skills are, in terms of looking for a job and areas of further self-study. I remember reading two interesting takes on what an entry level rails dev should know. The SO answer places me pretty comfortably at the entry level which makes me uncomfortable since I don't really feel job ready at all(partly because I have no idea what an entry level dev would do). Aside from some guided tutorial applications so far I've done one serious full app. It's a glorified blog with an ActiveAdmin backend, that can also send out a newsletter/manage subscriptions, does RSS and posts to its own FB page, can handle attachment files/images through paperclip and dropbox. Zurb Foundation front-end, no custom JS. Deployed to Heroku, running on PG. Also completely untested. The hardest part of the whole thing was probably figuring out the AA DSL and setting up the whole email system. Basically, it feels like I've bumped into most everything that web tutorials touch on and a bit more. As a designer I feel I have no idea what to do beyond looking at templates and copying them(though I feel comfortable with SCSS/html(as long as I know what look I want to produce), and copy-paste-tweak capable with js). In terms of the heavy programming(what would count as heavy?) I feel sort of comfortable identifying a problem and then googling around for a solution, but I struggle to identify the next step in the first place(yes, that's what TDD is for, I didn't use it for my first real app since I wanted to use ActiveAdmin). I feel like I can do any basic task as long as I can google for it, but I'm terrified of going into an interview since I use SO/railscasts/etc non-stop while I work. Looking at interview prep blog posts they talk about patterns and algorithm implementation which is stuff that I've never used for rails programming, so far(I think). Finally, the question, what do I do? Applying for a job is a bit of a non-starter since I'm Romanian and there's like one Rails company in the country. I think I can start looking for contract work just because from what PHP friends tell me most of their work is, pretty much, building glorified blogs/simple CMSs for small companies. I built a super basic e-commerce site with Spree months back and that seemed easy as well. Should I look for some open-source rails projects and contribute/study them(recommendations?) e. Sublime guy: why would you build anything? Save your files and reload whatever webpage you are working on. You started the server from the commandline, right? Sublime is just for editing your files, it doesn't run a server or show you browser output(ie. the actual web pages). e2. Here's a way overdetailed workflow intro with Sublime Text 2.

Err well, I just edited my post up there to clarify, but I'm not really working on web applications right now.

Ruby can do scripts, I think you just want to navigate into the file folder with the Terminal and then run "ruby filename.rb" which will execute the ruby file. Ruby doesn't build, I don't think, since it doesn't have a compiler. Just save your *.rb file and run it. e. "puts" prints to terminal, btw so you can have your first ruby program just be a file named "hello.rb" with the content "puts "hello"". Go in that folder with terminal and run it with "ruby hello.rb" e2. ruby is interpreted, not compiled, so I don't think you ever get to it producing a binary for you. Just run it from the command line. e3. Rails accounts for most of what Ruby is used for. I think Ruby is also used to for testing(from what I remember in old jobs posts I browsed) other programs, but it's very much a nice thing.

I'm not sure. I would assume you can just have an executable file that's essentially a wrapper that issues command-line type commands when you click it sort of like how I think bash script files work. e. see this for packaging ruby scripts into an app on OS X Sil fucked around with this message at 20:37 on Aug 21, 2013 |

Especially if you remote connect to your development machine, never lose a thing from disconnect/reboots/crashes again. Also, to go back to the cucumber thing a bit ago: Don't, don't, don't use it if you work by yourself or stakeholders(  ) aren't going to look at them. It's a complete waste of time and a maintenance nightmare. Just use rspec+capybara.

A little late to the whole RSpec thing but the problem I've always had with it is that the semantics seem to change with every other version and the team working on it can't stick to anything. I haven't really used Cucumber all that much and it seems like it could become a bit bloated, although it seems more straightforward than RSpec in a lot of ways because you only end up with the natural language in the feature file opposed to a bunch of ugly code blocks everywhere. What is the deal with Shoulda? Just glancing at the Github readme it kind of seems like a cut down RSpec (with regards to being based around shoulds)? I have a few projects I'm working on where at least a couple of them might need some test rewrites, so I could probably do some experimenting this weekend.

Quick question about assigning class variables: Can I do something like foo.bar.baz = foo? Specifically, for doing binary tree peer linking, can I say node.left.nextright = othernode? I'm getting a nomethoderror, so what I guess is happening is it thinks that nextright is a non-existent method in the class, but nextright is one of the node class variables.

Try adding attr_accessor :nextright to the class. Instance variables are private in ruby, the only way you can modify them from outside is via methods.

It works until someone hits the database at the same time as someone else. If you were using unicorn, this would happen any time two requests are submitted at the same time. You can't really test for the error, you just have to know that if you're using sqlite, you can only use one server process at a time.
