Trouble-Free Bundler

Every couple of weeks, I hear someone complaining about some difficulties with Bundler. Yesterday, it happened twice. But somehow I just never have those difficulties. I'm not saying Bundler is perfect; certainly in its early days it wasn't even close. But for the past two years it's been incredibly solid and trouble-free for me, and I think a large part of the reason is the way I use it. Bundler arguably does too much, and just as with Git, a big part of it is knowing what not to do, and configuring things to avoid the trouble spots.

remap prefix to Control + a
