Git Checkout at Previous Timeframe
In the past I've blogged about checking out branches created on a specific date as well as sorting git branches by date, but one frequent usage of git and dates is checking out a commit at a given time in the past. For example, I often say "Weird, this feature was working a month ago" or "We removed that UI two months ago, how did it look again?". I don't care about the branch previous to the change, I just want to go back a given timeframe and see something.
The following git command allows you checkout the commit closest to the given date and time:
git checkout 'master@{2018-09-01 01:00:00}'
This command is incredibly useful -- I use it almost daily!

One of the worst kept secrets about AJAX on the web is that the underlying API for it, XMLHttpRequest, wasn't really made for what we've been using it for. We've done well to create elegant APIs around XHR but we know we can do better. Our effort to...
![Do / Undo Functionality with MooTools]()
We all know that do/undo functionality is a God send for word processing apps. I've used those terms so often that I think of JavaScript actions in terms of "do" an "undo." I've put together a proof of concept Do/Undo class with MooTools.
The MooTools...
![Duplicate DeSandro’s CSS Effect]()
I recently stumbled upon David DeSandro's website when I saw a tweet stating that someone had stolen/hotlinked his website design and code, and he decided to do the only logical thing to retaliate: use some simple JavaScript goodness to inject unicorns into their page.
