Deployinator - Deploy code like Etsy

Deployinator is a deployment framework extracted from Etsy.

Here is a blog post explaining the rationale behind it and how it helps us out.

For anyone deploying code (engineers, designers… anyone really), it’s an easy process.
Once your code is ready to go, you go to Deployinator and push the button to get it on QA. From there it visits Princess (see the sidebar).

Then, when it’s ready to go live, you hit the “Prod” button and soon your code is live, and everyone in IRC knows who pushed what code, complete with a link to the diff.

For anyone not on IRC, there’s the email that everyone gets with the same information.

Rack-webconsole, a Ruby/Rails console inside your browser

Rack-webconsole is a Rack middleware that enhances your development experience providing a JavaScript-powered bridge to your Ruby application backend.

With it you can interact with your database and explore the runtime environment from within the browser.

Although it should be used mainly in development environments, I personally think it could be a useful tool for staging as well.

Avoids the pain interacting with some console over an SSH session :) Here you have a little video showing how it works (watch in HD, otherwise you won't see the tiny letters!):

 

Tripwire - Stop hurting your users

Jeffrey Chupp and Jeremy Weiskotten recently built a new web service aimed at supporting developers, called Tripwire.

It integrates with Rails and remotely logs your form validation errors.

With this information, you can find out where your users are having the most trouble and streamline your web application.

Tripwire is in private alpha but will be open to the world soon.

Yes, Slim is speedy

Slim
Slim is a template language whose goal is to reduce the view syntax to the essential parts without becoming cryptic.

What?

Slim is a fast, lightweight templating engine with support for Rails 3. It has been tested on Ruby 1.9.2 and Ruby/REE 1.8.7.

Slim's core syntax is guided by one thought: "What's the minimum required to make this work".

As more people have contributed to Slim, there have been optional syntax additions influenced from their use of Haml and Jade. The Slim team is open to these optional additions because we know beauty is in the eye of the beholder.

Slim uses Temple for parsing/compilation and is also integrated into Tilt, so it can be used together with Sinatra or plain Rack.

Sample View:

doctype html
html
  head
    title Slim Examples
    meta name="keywords" content="template language"

  body
    h1 Markup examples
    #content.example1
      p Nest by indentation

    = yield

    - unless items.empty?
      table
        - for item in items do
          tr
            td = item.name
            td = item.price
    - else
      p No items found

    #footer

    = render 'tracking_code'

    script
      | $(content).do_something();

Digging Into The Rails Command Line

Have you ever wondered what happens behind the scenes when you start your server using the following command: ?

Rails 2.3.14, 3.0.10 and 3.1.0-rc6 Released

The Rails developers have pushed out three new releases in tandem to fix the same security vulnerabilities. All three major branches have been covered. The vulnerabilities include:

• SQL injection vulnerability
• A way for attackers to render a view without first calling the corresponding action
• A XSS vulnerability in the strip_tags helper
• Another XSS vulnerability, this time having to do with the UTF8 parsing code

It's recommended that everyone upgrade, as the SQL injection and XSS vulnerabilities can be particularly damaging.
