Mac web developer apps

This gist's comment stream is a collection of webdev apps for OS X. Feel free to add links to apps you like, just make sure you add some context to what it does — either from the creator's website or your own thoughts.

This article has been given a more permanent home on my blog. Also, since it was first written, the development of the Promises/A+ specification has made the original emphasis on Promises/A seem somewhat outdated.

You're Missing the Point of Promises

Promises are a software abstraction that makes working with asynchronous operations much more pleasant. In the most basic definition, your code will move from continuation-passing style:

getTweetsFor("domenic", function (err, results) {
 // the rest of your code goes here.

Routes

小心地使用 Match（Rails 3 已实现）

Rails 3 提供了 match 方法供我们自定义 routes，然而我们要小心使用它以避免“跨站脚本攻击”（XSS Attack）。比如像这样的 routes：

注：（r3 代表 Rails 3，r4 代表 Rails 4）

# routes.rb

Update and upgrade the system

sudo apt-get update && sudo apt-get upgrade && sudo apt-get dist-upgrade && sudo apt-get autoremove
sudo reboot

Web fonts are pretty much all the rage. Using a CDN for font libraries, like TypeKit or Google Fonts, will be a great solution for many projects. For others, this is not an option. Especially when you are creating a custom icon library for your project.

Rails and the asset pipeline are great tools, but Rails has yet to get caught up in the custom web font craze.

As with all things Rails, there is more then one way to skin this cat. There is the recommended way, and then there are the other ways.

The recommended way

Here I will show how to update your Rails project so that you can use the asset pipeline appropriately and resource your files using the common Rails convention.

	* Only the releases of the stable versions are listed in principle. The releases of the unstable versions especially considered to be important are indicated as "not stable."
	* The branches used as the source of each releases are specified, and the branching timing of them are also shown. BTW, before subversionizing of the repository, the term called "trunk" was not used, but this list uses it in order to avoid confusion.
	* In order to show a historical backdrop, big conferences (RubyKaigi, RubyConf and Euruko) are also listed. About the venues of such conferences, general English notations are adopted, in my hope.
	* ruby_1_8_7 branch was recut from v1_8_7 tag after the 1.8.7 release because of an accident.
	* 1.2.1 release was canceled once, and the 2nd release called "repack" was performed. Although there were other examples similar to this, since the re-releases were performed during the same day, it does not write clearly in particular.
	* Since 1.0 was released with the date in large quantities, the mi
