Reasonable expectations on a $12 plan

It’s great to see so many Railers sign up with TextDrive. They’re a great host and I’m happy to be associated with them. But unfortunately, it appears that there’s some mismatch in expectations around what you get for a $12 plan.

What you do get is a slice of very reasonable specs on some great machines. What you don’t get is your personal system administrators. You should have your shit together before pushing it to TextDrive. Develop on your local machine, push to TextDrive when it works.

As explained, TextDrive is a shared host. That means its somewhat like a community park where everyone is responsible for cleaning up after their visit and behave with good manners. Think of your application as a park goer. Make sure its recently well-behaved by not taxing everyone else with needlessly sloppy queries or tough computations on every request.

Most importantly, though, is to be mindful about your support requests. As nice as it would be, the TextDrive system administrators can’t be part of your development effort debugging your application. They’re there in case the system as such is broke. So just like programmers should be careful before blaming the operating system for their program troubles, you should be careful before blaming TextDrive for yours.

TextDrive is a marvelous service. You get SSH, Rails, lighttpd, FastCGI, MySQL, SVN, PostgreSQL, and so much more for twelve dollars a month. 12. On top of that, they’re taking half of the profit from that to help Rails. I’d hate to see such a resource go away because unreasonable support requests and sloppy apps.

Let’s avoid The Tragedy of The Commons. Thanks.

Production Log Analyzer: Find slow pages

Eric Hodel has released the Production Log Analyzer:

The Production Analyzer lets you find out which pages on your site are dragging you down. pl_analyze requires the use of SyslogLogger (included) because the default Logger doesn’t give any way to associate lines logged to a request.

Hodel and crew used this to locate slow running pages in 43 Things. You can learn more at at PLA site.

Going to the good video store

Josh C from the Eggplant Coop sent me the funniest switcher quote I’ve seen in a while:

We compare moving to rails from our in-house perl web framework to the scene in “Clerks” where Randall goes to the good video store ;)


Verifying encoding approach to Action Mailer

If you’re deep into all the RFCs on email, we’d like your help ensuring that the latest approach to encoding with Action Mailer is sound. We’re going for an approach where encoding to subjects and headers are only applied if necessary. Please do have a look at ticket #955.

Brian McCallister to be preset Rails at ApacheCon

Under the session title of Cheap, Fast, and Good: You can have it all with Ruby on Rails, Brian McCallister will be presented at ApacheCon Europe 2005. The session will run for 60 minutes and features this abstract:

Ruby on Rails is a new web application framework which provides tools for everything from object/relational mapping to componentized views. It provides the architectural soundness of the Java Model 2 action/view frameworks with the rapid development and expressiveness of PHP. This session will teach you how to build sophisticated, scalable applications quickly using Ruby on Rails, the Apache Web Server, and PostgreSQL

ApacheCon Europe 2005 is going on in Stuttgart, Germany on the 18th through 22nd of July.

Rails 0.11.1: More Ajax, Verifications, SQL Server updated, loads of fixes

The Ajax wave is sweeping across Rails. In this release, we’ve added a :position option to both link_to_remote and form_remote_tag that can be set to either :before, :top, :bottom, or :after. These options make it possible to add new DOM elements to existing lists without replacing the whole list. When working on big lists that are in a fixed order anyway, there’s a considerable speed increase to be had.

Yellow Fade Technique
Additionally, we’ve implemented the first in a hopefully long series of packaged effects. This is the 37signals’ Yellow Fade Technique that’s now available as Effect.Highlight(id) — perfect for highlighting a new element that was just added with Ajax. If you have the Javascript chops to do other effects, please do help out. The wiki discussion page for Ajax in Rails already has great ideas for slide, fadeout, and squish.

Verifications in a whole new module for Action Pack that allows you to specify preconditions for you actions. They come in the form of “verify that these parameters are part of the request or redirect the user somewhere else (possibly adding a message to the flash)”. Or said in code:

verify :params => "post", :only => [ :create, :update ], :redirect_to => { :action => "index" }

SQL Server adapter updated
The Micrsoft SQL Server adapter is back in top form supporting both file uploads (albeit still restricted by SQL Server’s 7KB limit) and the new limit style. Thanks to DeLynn Berry for the quick update. Now only the DB2 adapter is not supporting the new limit style.

Loads of fixes
Iconv is no longer required to install Rails (but you’ll want it if you need to send/receive UTF-8 with Action Mailer), you can clone Active Records with floats, the dispatch.fcgi has been fixed, and a bunch of other things. In total, this release has 30 new features, additions, tweaks, and fixes.

See all the changes in the changelogs for Rails, Active Record, Action Pack, Active Support, Action Mailer, and Action Web Service.

Update: No application changes should be required. Just make sure that you copy over the latest prototype.js if you’re using Ajax.

P.S.: Many thanks to Florian Gross for the wonderful code snippet that allows for uploads to RubyForge automatically. This saved me the headache of releasing 12 files by hand one more time. And many thanks to Jamis Buck for the new template used for the API documentation.

eXPlain Project Management Tool

eXtreme Programming and Ruby on Rails is a wonderful fit. Besides the most excellent support for test-driven development, XP works a whole lot better when your code base is so small that breakthroughs in knowledge about the domain can be executed in as few refactorings as possible.

But if you want to get into XP, you naturally also have to get into the planning game. And that’s where the newly released eXPlain Project Management Tool by John Wilger (with help from Jim Weirich and Quentin Baker) comes in. Through a simple interface, you can manage stories, iterations, and milestones.

Wilger and friends even had the good sense to put up a demo application (admin/adminadmin) for you to try out.

Rapid adoption of Rails as documented by ML and IRC

If you should have any doubts that Rails is experiencing rapid adoption, consider this graph plotting the number of messages per day (as a raising average, high mark was 141 messages in a single day) on the mailing list:

On IRC, we’ve high-marked at 225 people and have more people than the #ruby-lang channel on most evenings.

Welcome all who’ve recently joined us!

IE5/5.5 compatibility wizard wanted

Do you know how to make Javascript work for IE5/5.5? We’d love to get some help making the new Javascript helpers as compatible as possible. So if you got the chops, please take a look at making sure that the prototype.js library and the associated helpers work on IE5/5.5. For more information, get in touch with me (nextangle) on #rubyonrails.
