Learning from Twitter

An issue popped up on Twitter this past week that caused the web site to be generally unusable for many users. It appears as if attempts to scroll were unbearably slow and caused the site to be unresponsive. The Twitter team investigated and determined that if they reverted the version of jQuery that they used […]

Google Cr-48 for Coding

The other day I saw the announcement for the new Chrome OS test laptop and decided to sign up on the off-chance that I might be able to snag one. In the request form I made it very clear that I would be attempting to use this laptop for development (easily my primary activity). Surprisingly […]
