I build things at Stripe. Follow me at @amfeng. Or hear more about what I like working on. May 8, 2014. Opening files in Github from Vim. I spend a lot of time nowadays doing code reviews and helping spin people up on Stripe (or more generally, distributing knowledge about our code base). One thing I found myself needing over and over again was the ability to show someone a file or some code over IM or Slack. Since we use Github to host our repositories, this is as easy as linking to the online file.

A couple of friends and I decided around a month ago that we wanted to get better at drawing, so we decided to embark on one of those "draw one thing every day for 365 days" projects. Well, if we're being realistic, for. 365 days—we even named ourselves "Approximately 1095" (1095 = 365 x 3). It's been really fun so far:. I'll write up a separate post later about how/where I'm posting these!
