Better hope you’ve halved your maintenance costs. Three times as productive? One third the maintenance costs. Otherwise, you’re…

What ORMs have taught me: just learn SQL (2014)
I’ve come to the conclusion that, for me, ORMs are more detriment than benefit. In short, they can be used to nicely augment working with SQL in a program, but they should not replace it.

C Isn't a Programming Language Anymore
Phantomderp and I have both recently been very aligned on a particular subject: being extremely angry about C ABIs and trying to fix them . Where we’re not aligned is why we’re mad about them.

Rust concepts I wish I learned earlier
This past month, I have been enthralled by the Rust programming language given its unique edge for writing memory-safe, modern programs.

Emacs 29.1
Today is a great day for Emacs - Emacs 29.1 has just been released1! Every Emacs release is special, but I haven’t been so excited about a new version of Emacs in ages. Why so?

Understanding the Git Workflow
If you don't understand the motivation behind Git's design, you're in for a world of hurt. With enough flags you can force Git to act the way you think it should instead of the way it wants to. But that's like using a screwdriver like a
