High-Level Problems with Git and How to Fix Them
When Git first came onto the scene in the mid 2000's, I was initially skeptical because of its horrible user interface. But once I learned it, I appreciated its speed and features - especially the ease at which you could create feature branches, merge, and even create commits offline (which was a big deal in the era…

Software compatibility and our own “User-Agent” problem
Sometimes you have to write code to do some ad-hoc things in order to make programs run in a variety of environments, but as time goes by, it could result in a tragicomical situation where ad-hoc features are built on other ad-hoc features. It is easy to identify that kind of problem, but in many cases, nobody can fix…

Finding bugs in Haskell code by proving it
Last week, I wrote a small nifty tool called bisect-binary , which semi-automates answering the question “To what extent can I fill this file up with zeroes and still have it working”. I wrote it it in Haskell, and part of the Haskell code, in the Intervals.hs module, is a data structure for “subsets of a file”…

Good engineers make terrible leaders
Yuval Noah Harari in his highly celebrated book Sapiens says that human values are shared myths and that there is no objective basis in humanism. I agree with him.
