I'm having trouble getting unicorn to launch correctly using launchctl. I have a Rails application on my macbook pro. It runs fine under Passenger, but I'd like to switch over to unicorn to test it out. I have the following unicorn.plist <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" ...
Can you please explain me, why despite of great ruby popularity for web applications thanks to rails framework it is still not used or very rarely used by linux users to create system apps/scripts. We can compare it to python, witch not only has django and others for web applications, but is also commonly used as scripting language in li...
So I thought I had fixed the problem posted in this question and I uninstalled Rails 3.0.0 with sudo gem uninstall rails -v 3.0.0, but then I had troubles with other things. I took rogerdpack's advice to a different level and uninstalled all of my ruby gems and mysql, then reinstalled them. Now I get the following: Icarus:temporary atg...
The pre/post increment/decrement operator (++ and --) are pretty standard programing language syntax (for procedural and object oriented languages, at least). Why doesn't Ruby support them? I understand you could accomplish the same thing with += and -=, but it just seems oddly arbitrary to exclude something like that, especially since...

I have installed PDFKit and wkhtmltopdf on my Ubuntu 8.04 server.

Please help! Mongodb crashed on my server. When I started the mongod backup I have no data in database! Looking at the data/db/ directory I have the following 5 files: mongo.lock production-mongodb 4k production-mongodb.0 64m production-mongodb.1 128m production-mongodb.ns 16m I think mongo has somehow started a new...
i need to require active record, but I am working outside of rails (here is why: Simple Ruby Input Validation Library). do I need to require the entire rails gem, or can i be DRYer? ...
I think I'm being stupid. rc = Mysql.new('CENSORED_HOST','username','password','db') release = rc.query('select * from wp_ribcage_releases where release_id = 1 limit 1') puts release["release_title"] rc.close And I am getting the following error: ribcage-connect.rb:17: undefined method `[]' for #<Mysql::Result:0x1011ee900> (NoMetho...

Consider the following scenario: You have an account model You have an external service which manages subscriptions (such as CheddarGetter). You do not want to create a customer on CG unless the data entered passed your own validations, and likewise you don't want to save the customer down to your own database unless CG accepts the cus...
I have a Rails application with over 2,000 examples in my RSpec tests. Needless to say, it's a large application and there's a lot to be tested. Running these tests at this point is very inefficient and because it takes so long, we're almost at the point of being discouraged from writing them before pushing a new build. I added --profile...
When I do just script/runner it gives me -bash: script/runner: Permission denied When I do sudo script/runner it gives me sudo: script/runner: command not found It only works when I do ruby script/runner. Why? Everywhere else I see people just run script/runner without the ruby in front of it... Is there a "fix" for this? It's causing ...
Hi, I have a string: "116,118,120,130" and will want to delete either the first, last or any value in between upon execution. To to this I was using: "116,118,120,130".gsub('118','') but the problem is the string contains an extra unnessesary comma: "116,,120,130" and if I use "116,118,120,130".gsub(',116','') it will remo...

I just downloaded Ruby 1.9.2, and I want it to completely replace the older version of Ruby (1.8.7) that I also have installed. (Mostly because I get confused when installing things with different versions floating around.) What's the best way to do this? Do I uninstall the older version? (If so, how?) Can I just replace the old ruby1.8...
I know that in Ruby 1.9 you can easily re-encode a string like this. s = s.encode('UTF-8') What is the equivalent in Ruby 1.8? What require lines does it need. All the tutorials I have seen are needlessly complicated and I don't understand what is going on. Cheers! ...
When I try to run tests from TextMate in Rails3 i get an error that I trace back to boot.rb.
