But a bad ice storm and the inability to find the right size tire chains derailed my plans, and I ended up in Anchorage instead. But because of that, I learned that they have a great fireworks show in Anchorage on New Year’s Eve. As I mentioned in my second Facebook post on that day, there’s an Alaska saying that goes, “There’s old pilots, and there’s bold pilots, but there ain’t no old and bold pilots.” A git log command to list developers that contributed to a release I just noticed that if you want to see which developers contributed to a software release when using git , you can use this git command: git shortlog -sn --no-merges 3.0.0-M1..3.0.0-M3 I just saw that on this Github page .

When I went to UL I lived in the basement of the house on the left, and when I went to A&M I lived in that brick and cinder block place on the right. As George Costanza would say, “An Al divided cannot stand.” Atom editor feature lets you see open/resolved Github PR comments If you ever have 169 comments on a Github pull request , I learned last week that the Atom editor has a nice feature that lets you see which comments are open or resolved. 169 thank you’s to whoever created that.

December 23, 2019: Nurse at the hospital, as part of a questionnaire: Do you feel suicidal? Me: Well, I want to be careful with this because I don’t want you to get the wrong idea ... I don’t mind living ... and I don’t mind dying, but this in-between stuff where you’re constantly sick and can’t work or have any fun ... it is ... very frustrating. Nurse: So ...

At first I started to panic a little and look for one, but then as I became more lucid I asked people, “What year is it?” They said it was 2021, so I relaxed. Later on as I observed several other dreams, I could see that they were continuations of previous dreams, though I had missed some dreams in between. As my body heals, I’m able to get back to the lucid state more now, and the fact that we have “ongoing dreams” — whether we can recall them or — never ceases to amaze me.
