Vim Plugins That I Use
This is an alphabetical list of vim plugins that I use. Alternate In C or C++ projects, source and header files often come in pairs. For example, there's utils.c and utils.h and you often need to edit both files at the same time. With Alternate, you can type the :A command and it will quickly switch between .c and .h files. If you're in a .c file, it will switch to the .h file, and if you're in a

A Proof That Unix Utility Sed Is Turing Complete
Many people are surprised to learn that sed, a seemingly simple text filtering program, is actually Turing complete. This realization prompts the question: how can a text processing utility achieve such computational power? The answer lies in sed's fundamental operations. Essentially, sed functions as a miniature assembly language, equipped with a comparison operation, branching capabilities, and
Here is why Emacs uses the Meta key
Remember my article on why vi uses hjkl keys? It got very popular so I thought I'd also do an article about Emacs. When Stallman and Steele created Emacs, they both worked at MIT's AI lab. The systems they worked on had these funny keyboards with a bunch of extra keys called Hyper, Super, Meta and Control. Meta was closer to the pinky finger so that's why it was adopted by Emacs. Hyper and Super n
My Favorite Books: Part One
Imagine a world where every line of code tells a story, and each algorithm unfolds like an intricate puzzle – this is where my love for books on programming, coding, and development comes alive. Recently, Fog Creek sparked a delightful conversation by asking me about my favorite books in these fields. As a self-confessed book nerd with an insatiable appetite for literature on computers, programmin
Being good at programming competitions correlates negatively with being good on the job
A couple of days ago I watched a How Computers Learn talk by Peter Norvig. In this talk, Peter talked about how Google did machine learning and at one point he mentioned that at Google they also applied machine learning to hiring. He said that one thing that was surprising to him was that being a winner at programming contests was a negative factor for performing well on the job. Peter added that
Deriving the Y-Combinator
In this post I'll derive the Y-combinator and explain all the steps taken. The key to understanding the Y-combinator is knowing precisely what it does. I am sure many people never understand Y-combinator because of this very reason, or because the introduction is too lengthy to comprehend. Therefore I'll give the shortest possible explanation of Y-combinator before I derive it so that you know wha
