We’ve passed the 3-year mark for when Rails first saw the light of day as a public release. It’s been an amazing ride, don’t you think?
Capistrano 2.0 is real. (What is Capistrano?)
Install it thus:gem install capistrano
It’s been through four preview releases, and has seen significant changes since 1.4.1. If you’re currently using 1.4.1, be sure to check out the upgrade documentation at http://www.capify.org. If you’re altogether new to Capistrano, you might like to read about getting started.
Since the last preview release (number four, version 1.99.3), the changes are primarily bug fixes, but the following featureish modifications snuck in, too:
- The uploader has added a tiny bit of sleep to prevent the CPU from going bonkers during uploads.
- You can specify the $CAPISTRANO:HOST$ placeholder in the filenames that you give to “put”, and it will be replaced with the actual host that the file is being uploaded to.
Also, some people reported SFTP uploads were hanging for them. If this happens to you, try adding the following line to the top of your recipe file:set :synchronous_connect, true
That will cause connections to the servers to be established serially, rather than in parallel, so if you’ve got a lot of servers that you are connecting to, it might make things a bit time-consuming. However, this appeared to work around the hanging SFTP issue.
Yes, there are a few of these. Two are of immediate significance:
- If you try to use the ‘put’ command to upload a file to two or more hosts via a gateway, you run a good chance of encountering “corrupted mac” errors. This is due to design flaws in Net::SSH and Net::SFTP, and (to my knowledge) cannot be worked around. The current best practice is to upload to a single host, and then use scp or rsync from the remote hosts to pull the file.
- A very few people have reported commands hanging inexplicably and infrequently. I suspect this is also due to flaws in Net::SSH, but I’m not certain yet.
The MySQL-dump blog posted on some observed rubyisms while evaluating a large ruby application. He highlights some potential problems with ActiveRecord that may come up, such as using “SELECT *”, character sets, unsigned integers, and constraints.
Wow, has it been two years already? Geoffrey’s been a major positive force in the Rails community even longer then that, starting with the humble Pluralizer, which helped us all figure out what table names our ActiveRecord models were supposed to be using. For his next podcast, he’s turning the tables and letting himself be interviewed by Dan Benjamin. Be sure to send in some challenging questions (see Geoffrey’s blog post for details).
Congrats on the milestone, Geoffrey, Scott, and everyone else that’s been involved with the Rails Podcast!
Jason Perry has started a survey at http://railsforge.com/, asking for community feedback on whether a Rails-specific forge-site would be useful or not. What are your thoughts? Head on over and let him know!
The Haml team recently announced the release of Haml 1.7, which is an alternative markup system that you can use in Rails, instead of the default ERb-based markup. Version 1.7 is significantly faster than previous releases (and is almost as fast as Rails’ default system, now!). There are a few other new features, too: read all about it in the release notes. Great work!
ActiveReload has just released Warehouse, a simple subversion browser written using Rails. It sports a beautiful UI and can handle the mundane task of user and permission management for you. It’s also being distributed in a unique fashion for most Rails applications. Instead of being hosted, it is sold and downloaded to be installed on your own server.
If you’re interested, check us out at the Warehouse site.
Michel Barbosa has completed his bachelor thesis Delivery of the Key Adoption Factors and Key Characteristics of Companies Using Ruby on Rails. It presents research he has done and conclusions the why and who of switchers.
I’m happy to see that “Joy in Development” was a key adoption factor for 92% of the people interviewed.
Rails to Italy is gathering the Italian Rails community in Pisa from October 26th through 27th. They’re open for registration and are still looking for speakers. The price to participate is €89 for registrations done before August 1st.
Zilia Iskoujina is a PhD student from the UK who’s doing research on Knowledge management and innovation in virtual organisations. As part of that, a questionaire for people working in open source has been created. If you have 15 minutes, consider filling it out.
