Rails is really a collection of pieces that can be put together to create a web app. You can enhance or replace many of the components - how you write views, how controllers work, and how you build models. While models are built on top of ActiveRecord in the

Ideas for new laws

These are ideas that came up during reading articles and discussions about the recent happenings in Ferguson.

New Laws

Some guidelines for doing a code review
View Code Review

Here are some general guidelines to consider when reviewing a pull request:

  • Is the code covered by tests? *
  • Are there any tests cases that are missing? *
    • Unit tests - for any model changes *
    • Acceptance tests - ???infrastructure needed
    • Integration tests - for any front end behavior change *
    • Black box testing? infrastructure needed
    • Controller tests - for any controller changes *
  • Rake / release tasks - manually run them? *

* '...' - Using for Atom.
* "..." - Using for Text.
* [...] - Using this for List (and maybe Map).
* {...} - Using this for Block.
* <...> - No good, as it's too hard to parse differently than < and >.
* (...) - Already overloaded for precedence and method call invocation. Tuple?
* [<...>] - Looks like a really good choice. Map?
* [!...!] - Might be too hard to parse ! inside a List then. (Unless we don't have a ! operator.)
* [@...@] - Probably too hard to parse $ sigil inside a List then.
* [#...#] - Probably too hard to parse comments then. Might use for nestable block comments.

Prerequisites for HTTP Workshop

Please have Vagrant and VirtualBox installed ahead of the workshop, if possible. We'll be providing a virtual machine (on USB keys) with the lab exercises. Having Vagrant ready to run the VM will help us get started quickly. That said, we'll have a few minutes of slide presentation to get started. You might be able to get things working then. If you're unable to get Vagrant working, we'll have you pair up with a neighbor.

You can’t perform that action at this time.
