List Conflicted files with Git
When you pull from a remote repository, the number of new files listed can sometimes cause conflict messages to get scrolled off the screen. Not very convenient. You can use the following command to get a quick list of conflicts from Git: git ls-files -u

The “catch” with try…catch
I’ve recently been working on an update to JavaScript Debug, which has me doing a lot of cross-browser testing, and I noticed a few “interesting quirks” with try…catch in Internet Explorer 6-8 that I couldn’t find documented anywhere. The Backstory Since the primary goal of JavaScript Debug is to normalize the console cross-browser, I’ve been […]
