What are symbols all about?

In case you’re wondering with it’s :controller => "weblog" and not just "controller" => "weblog", you want to read Kevin Clark’s Understanding Ruby Symbols. It gives a number of angles on why symbols exist and why they make sense to use.

Geary makes the Java jaws drop on Rails demo

David Geary has moved into the Rails café and is now spending a considerable amount of time telling others about this place. Most recently, he did just that again at the No Fluff, Just Stuff symposium in Salt Lake City. His presentation left more than a few jaws hanging:

Near the end of that demo, I looked into the audience and saw something that I’d never seen at a NFJS symposium: a woman sitting at a table near the front of the room was looking at me with her mouth wide open and the most incredulous look on her face. It was almost like I could read her mind: “This can’t be real!”, she must’ve been thinking. I pointed at her and said “That’s pretty amazing, huh?” She nodded a reply, but the look of astonishment never left her face.

The language and environment you choose to work with those make a large difference on productivity. Smart people can succeed with nearly anything, but that doesn’t mean they shouldn’t look for that edge whenever they can find it.

Rails jobs aplenty: Six new open positions!

The Rails job market continues to pick up pace. Here are a total of six new positions open for developers ready to leave the old world behind and join the hundreds of people working with Ruby on Rails professionally:

  • Site5 is looking for two senior Rails developers and one Rails designer/developer to join their already sizable Rails development team. The latter is specified as the “…ideal developer/designer candidate has a complete understanding of both user interface design and object-oriented programming”. Contact Matt Lightner to apply.
  • Money Management Group are looking for a Quantitative Systems Developer (whatever that means exactly) to help them use Ruby on Rails to develop, manage, and test trading systems for their dealings in the financial sector.
  • Vespa is looking for preferably a Denver-native (but could be telecommuting) developer to help them finish a Ruby on Rails system and be “…comfortable with complex database design and relations”. Write Dale Hawkins to apply.

Strongspace: Secure file storage by TextDrive

Strongspace is a smashing new Rails-powered service from TextDrive. Their pick-up line goes as follows:

Strongspace is a secure place to gather, store, back-up and share any type of file with your co-workers, friends and family. You can upload, download and manage your files over SFTP (Secure FTP) or with any modern web browser.

It’s a place in the sky without all the overhead of maintaining a real hosting environment for it. Just targeted space at great prices. They start at $8/month for 4 gigabytes of space. It’s a perfect fit for Basecamp space too. They even have a movie showing how easy it is to setup your Basecamp account to use Strongspace.

The application itself is also wonderfully designed and delivered by the Rails’ team at TextDrive consisting of Michael Koziarski, Marten Veldthuis, Johan Sörensen, and Justin French. Congratulations on the launch, guys.

Apple makes note of Ruby on Rails

On the Apple Developer site, there’s a new article about open-source scripting languages and how you can use Xcode to work with them. On Ruby, they note:

Ruby is gaining popularity as a language to write web-based applications. Ruby scripts can easily be executed with CGI, and Ruby contains a class called CGI that is used specifically for creating CGI scripts. The CGI class has methods for generating HTML and dealing with cookies, among many other capabilities. If you are considering using Ruby to write web-based applications, you won’t want to miss the Ruby on Rails project. Rails is an open source web programming framework that is rapidly gaining mindshare due to its simplicity and clean design.

Thanks, guys.

Sparklines for Ruby on Rails

Geoff Grosenbach has implemented a really cool Sparklines library for Ruby that even ships with helpers for Rails. A few examples:

Pie—Shows a single percentage
Smooth—Shows continuous data
Area—Highlights data with a colored threshold
Discrete—Uses vertical lines

The Rails wiki returns, plans for Madeleine replacement

The Rails wiki has returned in a trimmed form that abandoned all the previous revisions in order to make Madeleine cope with the pressure. We’ve surely pressed the backend far beyond its original, humble, personal wiki intentions. With tens of thousands of page revisions, it was just choking.

But have no fear. Instiki will soon be available in a database-backed version that’ll be more suitable for public wikis the size of the Rails one.

Calming Anil Dash's concerns of shiny technology

Anil Dash from Six Apart is worried that Blinksale is getting attention for all the wrong reasons. That just because it’s using Ruby on Rails, features snappy Ajax, and is built by a small team it should be inherently deserving of attention. Christian from xml-blog tries his hand at explaining to Anil why it is indeed exciting, at least in regards to Rails:

What I will say is that I understand why Rails/Ajax enthusiasts get so excited about every new product built on Rails that sees the light of day. First, it’s well documented that few IT projects ever make it to production. Second, once you’ve actually worked with Rails, you tend to fall in love with it. This is not some sort of new-kid-on-the-block infatuation; it’s a kind of thankful love born of the countless hours Rails shaves off your development time letting you concentrate on the very thing Anil is concerned about: building apps that meet a need or solve a real-world problem. Lastly, it’s a bit of cheerful exuberance at seeing that mere mortals are indeed able to complete a plan-build-deploy cycle for a real-world Rails application in short time and have it withstand all the traffic that invariably will be thrown at it.

To add my own two cents, I think it’s very exciting to see Blinksale go live using the technology and approach to software development that we’re championing at 37signals. It shows that others are more than able to use our tools and thoughts to achieve good things, which again encourages the belief that Rails and Getting Real are indeed not specific to a single crew — but that you can use them too to similar effect.

Oh, and Blinksale does work very nicely for sending out invoices, too ;). 37signals already sent our first real invoice through the system.

Reusing parts of database.yml with YAML trick

The RedHanded _why features a neat YAML trick today that lets you reuse parts of the database.yml configuration file. So instead of specifying the same login over in all three environments, you just do it once and merge. Nifty!
