OS X Screencast to animated GIF

This gist shows how to create a GIF screencast using only free OS X tools: QuickTime, ffmpeg, and gifsicle.

Instructions

To capture the video (filesize: 19MB), using the free "QuickTime Player" application:

PSQL

Magic words:

psql -U postgres

Some interesting flags (to see all, use -h or --help depending on your psql version):

• -E: will describe the underlaying queries of the \ commands (cool for learning!)
• -l: psql will list all databases and then exit (useful if the user you connect with doesn't has a default database, like at AWS RDS)

Alright, thank you. 
So, I’ve got about apparently I’ve got about five to six minutes to say the most useful things I can think of. 
I’m gonna do my best. 
It was suggested that I distill things down to 3 items. 
I think I’ll go with four. 
And I’ll try, I think, I think these are pretty important ones. 
Some of it may kinda sound like, well you’ve heard them before. 
But, you know, worth reemphasizing. 

I think the first is, you need to work, if you, depending on how well you want to do,

Thoughts on Swift 2 Errors

When Swift was first announced, I was gratified to see that one of the (few) philosophies that it shared with Objective-C was that exceptions should not be used for control flow, only for highlighting fatal programming errors at development time.

So it came as a surprise to me when Swift 2 brought (What appeared to be) traditional exception handling to the language.

Similarly surprised were the functional Swift programmers, who had put their faith in the Haskell-style approach to error handling, where every function returns an enum (or monad, if you like) containing either a valid result or an error. This seemed like a natural fit for Swift, so why did Apple instead opt for a solution originally designed for clumsy imperative languages?

I'm going to cover three things in this post:

if ( ! function_exists('config_path'))

     * Get the configuration path.
     *
     * @param  string $path
     * @return string
     */
