On undoing, fixing, or removing commits in git

A git choose-your-own-adventure!

This document is an attempt to be a fairly comprehensive guide to recovering from what you did not mean to do when using git. It isn't that git is so complicated that you need a large document to take care or your particular problem, it is more that the set of things that you might have done is so large that different techniques are needed depending on exactly what you have done and what you want to have happen.

How to get started to build your own Spacemacs	2018-10-12 12:59	emacs	Tools

I have been a Vim user for quite a while. I love it, so the very first thing when I set up a new server is installing VIM. I heard a lot about Emacs and tried it. It's better at almost everything except text editing. So I stayed with Vim until Spacemacs was released. The Vim key bindings of Spacemacs is so excellent that I switched.

However, Spacemacs has its problem: boots up slowly and crashes frequently. Upgrading packages became very challenging. Finally, I have to use the develop branch because the master branch is not working anymore. People began to complain and requested to speed up the release from the master branch. Considering its dependencies and numerous open issues, I have no hope for this.
