A Fresh Cup

Posting is going to be irregular for a while, I expect: here’s why

• pure class – I’m going to need to use one of these techniques for tracking down things through ActiveRecord extensions soon, I think.
• Twitter4R 0.2.0: Twitter API for Ruby – There are now two different Ruby libraries for accessing the Twitter API. Some people would say that is two too many.
• Connector and Slingshot Open-sourced and Free – The Joyent guys are giving away a big ol’ gob of code.

We’re trying to prep our house to put it on the market. This sucks down a great deal of time, and explains why posting may be spottier than usual for a little bit.

• How to Create Many to Many Relationships in Ruby on Rails – One of the basic skills, but it does point out creating the join table, which is easy to miss the first time you set up such a relationship. (via dzone)
• Haml 1.7 has been released! – Alternative markup language for Rails views. Lots of perf work in the last few releases, so it’s becoming a more viable alternative, at that.
• Using Omnigraffle to visualise Rails model associations – I could have used this about a week before I found it, since I spent a big chunk of that week drawing ERDs to understand a pile of existing Rails models. This one uses code to reflect over the models and build ERDs automatically.
• Warehouse Subversion Browser Released! – This is the SVN browser in Rails from the ActiveReload folks. Now available for a one-time $30 fee.
• Replacing Ant With Rake – Here’s how you can call all your ant tasks as if they were rake tasks, and so switch to rake for ongoing maintenance of your ant files.

A few random links for the Fourth of July.

• Information Card Ruby – Yes, you can now make InfoCard play with Rails, if you must. This will be a good thing for those trying to smuggle Rails into Microsoft shops.
• Mingle is Now Available – That would be the new agile project management tool from ThoughtWorks, now in an Early Access release.
• Comatose – Micro-CMS implemented as a Rails plugin, to handle editing of those few semi-static pages that pile up in every application.

I’m getting to the point where I’m finding more interesting links for my new blog than for my old one. This is a good sign of transition, I think.

• Condition Builder 1.1 – Helper to easily generate SQL WHERE conditions for Rails. (via Same Shirt Every Day)
• UserEngine – Roles and permissions for Rails. Bookmarked ‘cause I’ve got a customer who wants to use this. Only they don’t want to use an engine. Hmm.
• Capistrano 2.0 Preview 4 – One more iteration of the next Capistrano release.

Time to repost another few links for my own reference and yours.

• I’m on Rails: Coding Statistics. – I ended up swiping pieces of this to do outbound link tracking in an application I’m working on.
• rails plugin list – More plugins than you can shake a stick at, along with where to grab them from. You have to guess their use from their names, though.
• Installing Xen on Ubuntu Feisty Fawn – the complete newbie’s guide – I hope not to have to tackle this any time soon, but if I do, this looks like a good unified guide.

There are always about a million little fiddly bits to do to get an application out the door, aren’t there?

• Backing Up Your Mac – Recently-revised article from MacZealots listing some easy alternatives. Doesn’t answer all of my questions but it’s a good starting point.
• mirRoR Placement – A pure Rails job shop. It’s another sign of the rapid growth of the Rails ecosystem that we’re seeing firms like this pop up.
• Announcing Multisite Plugin for Rails – Serve multiple domains from a single Rails application by giving each a distinct set of views.

Woo, starting another consulting job today, without a speck of MS stuff in sight. I feel all vindicated and stuff.

• iStat Menus – There are about a million different Mac system monitors out there. This one is free and doesn’t take up screen real estate when you don’t want it to.
• VSS to SVN: Part 3 – This tutorial for source code control switchers continues.
• Ruby on Rails EC2 ‘Appliance’ – Practically turnkey Rails deployment to the Amazon server cloud. (via Ruby Insie)
• Sake Bomb – Sake is system-wide Rake. Looks like it still has some warts, but is already useful

With a second Rails contract about to be signed, I guess I really am a Rails consultant now. How about that?

• file_column plugin and Capistrano – By default the file_column plugin saves under /public, which doesn’t play well with Capistrano. Fortunately the fix is simple.
• Rails Hackfests – The Hackfests, recognizing contributions to the Rails source code, have gone monthly.
• Installing Ruby on Rails and PostgreSQL on OS X, Second Edition – Revision to a popular and useful how-to article.

It’s Monday, it’s time for some new links

• Starting Ruby on Rails: What I Wish I Knew – Some pointers for getting started. (via dzone)
• Versions – Subversion GUI for OS X, now going into private beta.
• Capistrano 2.0 Preview 3 – Apparently getting close to release.

Looks like I may not starve to death this year after all. That would be welcome evidence that the universe is listening to me.

• “Script.aculo.us – Offline Docs”: http://www.m3nt0r.de/blog/scriptaculous-offline-docs/ – The contents of the Script.aculo.us wiki reformatted as CHM and PDF. (via Thomas Fuchs)
• Ruby In Steel 1.1 Now Available! – An upgrade for folks working with Rails in the Visual Studio shell on Windows.
• Google Analytics Plugin – A simple way to hook up Analytics to a Rails application.

I’ve finished getting my first production Rails server up and running at RimuHosting . I kept reasonably careful notes along the way, and now I’m going to brain-dump them here, in part because I might need them again in the future, and in part because they might help someone else. Of course, there are so many variables that your setup very likely will not be a precise match for my setup, so use with appropriate caution.

We started with a MiroVPS3 (224MB) host with Debian Etch, the Webmin control panel, and RimuHosting’s own basic Rails stack preinstalled. That’s probably overkill for this little app, but the client wanted to be sure of plenty of breathing room. I’m targeting Apache + Mongrel for serving pages because that’s what I’ve been using in development and staging; production is not the time to experiment with a new-to-me server.

1. ssh root@nn.nn.nn.nn
2. adduser mike
3. logout
4. ssh mike@nn.nn.nn.nn
5. started mysql via Webmin control panel
6. changed mysql root user password to DBPassword via Webmin control panel
7. set up mike as a full admin using sudo by using visudo
8. sudo adduser appuser
9. mysql -u root -p
10. CREATE DATABASE appproduction;
11. GRANT ALL PRIVILEGES ON appproduction.* TO ‘appuser’@’localhost’ IDENTIFIED BY ‘apppassword’ WITH GRANT OPTION;
12. quit; get out of mysql
13. used Webmin to set mysql to listen on any
14. sudo apt-get install libopenssl-ruby1.8 Without this step, recent Rails won’t run properly on Ubuntu or Debian
15. mkdir /Library
16. cd /Library
17. sudo mkdir Rails -p -m 777 I like to keep my Rails apps in /Library/Rails. Your mileage may vary.
18. changed server info in deploy.rb to point to the production server
19. (on development machine) cap setup
20. sudo gem install—include-dependencies mongrel_cluster
21. (on development machine) cap deploy
22. cd /Library/Rails/app/current
23. rake db:migrate RAILS_ENV=production
24. cd /etc/apache2/sites-enabled
25. sudo nano 000-default edited this to basically match my staging version
26. sudo a2enmod proxy_balancer
27. sudo a2enmod proxy_http
28. sudo a2enmod rewrite
29. sudo /etc/init.d/apache2 force-reload
30. sudo /etc/init.d/apache2 restart
31. used Webmin control panel to set mysql to start at boot
32. sudo ln -s /usr/lib/ruby/gems/1.8/gems/mongrel_cluster-0.2.1/resources/mongrel_cluster /etc/init.d/mongrel_cluster
33. sudo chmod +x /etc/init.d/mongrel_cluster
34. sudo mkdir /etc/mongrel_cluster
35. sudo ln -s /Libray/Rails/app/current/config/mongrel_cluster.yml /etc/mongrel_cluster/nrafh.yml
36. used Webmin to set mongrel_cluster to start at boot time

First client Rails app successfully up and running at RimuHosting. I’ll be writing up my notes for future reference soon. Meanwhile, a few links.

• SimpleLog – A Rails weblog application I hadn’t run across before. By the way, I know my RSS feed for this one is still goofy; I’ll take a look when I’ve got spare cycles. Thanks for your forbearance. (via Same Shirt Every Day)
• Scripting Second Life with Rational Application Developer- – IBM continues to take Second Life seriously. There are also a bunch of crossover events from this week’s IBM/Rational conference being held in Second Life.
• JRuby 1.0 – The JRuby team announces full Ruby compatibility. I don’t personally have a whole lot of interest in JRuby (my ambition is to never work in an “enterprise” again), but it’s a nice validation point for the community.
• Rails Business: Weekly Review #1 – Roundup from one of the mailing lists spawned by this year’s RailsConf.

You know, I was worried about “slippery slope” censorship issues 20 years ago in zinedom, and here I am worrying about them again in Second Life. Some things just never change.

• New Noobkit is up! – This online Rails/Ruby documentation site has new APIs, comments, and other improvements.
• FiveRuns: First Production Rails Management Suite – Basic overview and interview at InfoQ. (via dzone)

Ah, a new work week is always full of such promise, isn’t it?

• “Setting Up Ruby (and Rails) For Ruby In Steel – From Scratch”: http://www.sapphiresteel.com/Setting-Up-Ruby-and-Rails-For-Ruby – Step-by-step guide to one easy way to get going with Rails on Windows.
• There can be only one, a tale about Ruby, IronRuby, MS and whatnot – There’s a lot of discussion in the Ruby community these days about the potential impact of Microsoft’s forthcoming IronRuby implementation. This is one of the best summaries I’ve seen.

In case it hasn’t been blindingly obvious, I’m ready to start talking to folks about Rails contracting. If you’ve got work on the web that needs doing, let’s chat.

• Sneak Peek: What We Built While You Were At RailsConf – The folks behind Lighthouse and Mephisto are working on a Rails-backed web-based Subversion browser.
• Komodo IDE 4.1 -This half-price promo is marked as being for RailsConf attendees, but they don’t seem to be verifying and the promo code is hanging right out on the web page. $147.50 instead of $295 for this Rails IDE.
• The Rails Documentation Project – Site tracking the big community-funded overhaul of the Rails API docs and associated projects.
• A Guide to Testing the Rails – Big tutorial on Rails testing, if you’re still not Doing The Right Thing.
• “Backhoe” – Large-scale Second Life terraforming tool. Only useful if you’re investing crazy amounts of money.
