• Mainstream Linux on 1GB HDD

  - by Ariel Nundi

  Hi, I've decided to start learning Linux + Ryby + RoR. The problem is the only personal computer I have is a laptop with 1GB flash card and I can't afford to buy more hardware right now. The laptop has dual core CPU and 2GB of RAM. Can you recommend a Linux distribution I can install? I've tried the netbook version of Ubuntu, but install failed because of lack of space. I'd prefer a more popular distribution, so I can use my skills say on a job. TIA

• Run Rails 3 app on a Rails 2 server/machine?

  - by chucknelson

  I'm trying to run a Rail 3 (3.0.10) app on a shared joyent smartmachine server (I don't have root access) which has Rails 2 (2.3.11) installed , and I'm not sure what to do after I freeze my Rails 3 app with bundle install --deployment. It seems like with the Rails 3 and bundler gems not being installed on the server locally, my app isn't even recognizing the local version of Rails I have frozen with my app. Has anyone gotten this to work, or have any advice? The server runs Apache, and I think I can get lighttpd installed too - but I'd rather stay with Apache if I can. Also, if it matters, Passenger is not an installed gem either...and I'm not sure I can freeze that with my app. Update 11/30/2011 12:30 PM EST Bundler is not installed on this server, either. Not sure if having that would enable the new Rails 3 "freeze" (bundle --deployment) to work or not...

• Two threads in a rails initializer file seems to not run them properly

  - by Luccas

  Initially I was using one thread to listen a queue from amazon and works perfectly. aws.rb Thread.new do queue1 = AWS::SQS::Queue.new(SQSADDR['my_queue']) queue1.poll do |msg| ... but now I appended another thread to listen another queue: ... Thread.new do queue2 = AWS::SQS::Queue.new(SQSADDR['my_another_queue']) queue2.poll do |msg| ... and now it seems to not work. Only the last one receives response... I have to join the threads? I can't understand What is going on?

• What happens when Phusion PassengerMaxPoolSize is reached?

  - by bmurtagh

  The subject of my post pretty much sums up my question: What happens when PassengerMaxPoolSize is reached? For Example: PassengerMaxPoolSize is configured to 40 based off our system specs What happens if all 40 sessions are active (processing a request) and our load balancer passes another session to this particular web server? This would send a 41st session to be processed without an available Passenger process.

• installing by_star gem?

  - by keruilin

  Can someone shed light on how to setup by_star gem: https://rubygems.org/gems/by_star? I ran ruby script/plugin install git://github.com/radar/by_star.git. However, when I went to call a by_star method in one of my models from console, I got an undefined method error. Do I need include or require statement? Could I be missing dependent gems?

• How can I create specialized builders for semantic layout in rails?

  - by Paul Alexander

  This is how I'd like to write markup in say index.html.erb <%= page_for "Super Cool Page" do |p| %> <%= p.header do %> Ruby is Cool <% end %> <%= p.body do %> Witty discourse on Ruby. <% end %> <% if page.has_sidebar? %> <%= p.sidebar do %> <ul><li>Option 1</li></ul> <% end %> <% end %> <% end %> Which would output <div class="page"> <header><h1>Super Cool Page</h1></header> <section> Witty discourse on Ruby. </section> </div> and when page.has_sidebar? is true <div class="page"> <header><h1>Super Cool Page</h1></header> <asside><ul><li>Option 1</li></ul></asside> <section> Witty discourse on Ruby. </section> </div> I've taken a look at the FormHelper class in rails for guidance, but it seems like I'd have to duplicate a lot of work which I'm trying to avoid. I'm really just trying to figure out where to hang the classes/modules/methods in the framework and whit kind of object |p| should be. My first inclination was to create a PageBuilder class that implements header, body and sidebar methods. But I got stuck on the rendering pipeline to get everything output just right. Is there a gem that already provides this type of semantic generation? If not I'd love any insight on how to set this up.

• Profile memory-performance for part of an rails project

  - by Florian Pilz

  I want to test the profile usage of an important library-class of my rails-project. It uses ActiveRecord so I need all rails dependencies to profile it. As far as I know, I need a patched ruby (rubygc) so script/profile and script/benchmark can track memory usage. I tried to follow this official guide to patch the source code of ruby 1.8.6 (p399) and 1.8.7 (p248), but both fail with the following message: patching file gc.c Hunk #2 succeeded at 50 with fuzz 2 (offset 2 lines). Hunk #3 succeeded at 87 with fuzz 2 (offset 6 lines). Hunk #4 succeeded at 153 with fuzz 1 (offset 45 lines). Hunk #5 succeeded at 409 with fuzz 2 (offset 274 lines). Hunk #6 FAILED at 462. Hunk #7 FAILED at 506. Hunk #8 FAILED at 520. Hunk #9 FAILED at 745. Hunk #10 FAILED at 754. Hunk #11 FAILED at 923. Hunk #12 succeeded at 711 (offset 46 lines).

Hunk #28 succeeded at 2628 (offset 102 lines). 8 out of 28 hunks FAILED -- saving rejects to file gc.c.rej patching file intern.h Hunk #1 succeeded at 268 (offset 15 lines). I also tried to use ruby-prof, but I always get the error "uninitialized constant RubyProf::Test". I don't know how to use the gem "memory" and neither "memprof" nor "bleak_house" could be installed successfully. If I get a patched ruby running, I should be fine. But any other possibility to profile the memory of library classes are welcome. Thanks for helping!

• how to specify a BIGINT in a rails scaffold?

  - by webdestroya

  I am trying to create a model in ruby that uses a BIGINT datatype (as opposed to the INT done by :integer). I have search all over Google, but all I seem to find is "run an SQL statement to alter the table to a BIGINT" - This seems a bit hack-ish to me, so I wanted to know if there was a way to specify a bigint in the ruby system like :big_int or something Any ideas?

• Create web application with ajax from the begining or add ajax later?

  - by klew

  I'm working on my first Ruby on Rails aplication and it's quite big (at least for me ;) - database has about 25 tables). I'm still learning Ruby and Rails and I never wrote anything in Javascript nor Ajax. Should I add Ajax to my application from the begining? Or maybe it will be better to add it latter? Or in the other words: is it (relatively) easy to add ajax to existing web application?

• How do I uninstall a ruby version installed via source?

  - by Aaron McIver

  I installed a version (1.9.3-p194) of ruby via source using make install and realized this may have been the wrong route to take. Upon doing this, I realized this was a mistake and I should be using a solution such as rvm to address my ruby versions within the OS. I looked to see if an uninstall existed to be ran in conjunction with make and it didn't. I then proceeded to install rvm and add the aforementioned version in to my list of managed rubies within rvm which is not listed as ext-ruby-1.9.3-p194. rvm rubies ext-ruby-1.9.3-p194 [ x86_64 ] =* ruby-1.9.3-p194 [ x86_64 ] # => - current # =* - current && default # * - default** When I perform an rvm remove, it simply removes it from the rubies list however it still exists within /usr/local/bin. I am not concerned with the system install ruby version residing in /usr/bin as I understand that is tied to the OS and should simply be ignored. How can I safely uninstall/remove the aforementioned version and all the places in which it was installed, short of looking at the install script?

• Please help to clean up my RoR development environment

  - by PeterWong

  I started RoR development a few months ago, and being new to Mac... Time flies and now I have a lot different ruby versions, rails versions and gems versions located everywhere......And currently I installed rvm and things got even worst, all things messed! And so I started want to clean all things and use rvm again! I want to uninstall all gems, all rails, and all ruby versions, except the system's default one (the very old one born with the mac). Or any other better solutions or suggestions!?

• Is it possible to use RubyGnome2's/QtRuby's HTML renderers to make UI for a Ruby script?

  - by mjr

  I'd like to make a graphical user interface for my script, instead of running it from the console. I'm aware there's a wealth of UI libraries for Ruby, but I'm quite familiar with HTML and CSS and I'd like to use them for building an interface. So the question is: Is it possible to use a HTML rendering library to make such an UI? From what I understand, it's relatively easy to put in a HTML rendered view of something, but is it possible to communicate back with the script? Like when I push that big red button, it actually tells the script to act on it? Obviously it's possible if the script run on the server side, but I'd like to run it as a desktop application.
