Blogs have become one of the most effective outlets for teaching and learning about all things computer science and computer programming. While some computer science blogs are made up of the interesting musings of various tech types, others are helpful how-to’s covering everything from building a website to building a computer. Despite their many differences, the best blogs are entertaining, informative, and well-written. Keep scrolling for this year’s rundown of the top 30 computer science and programming blogs!

11011110 

To come up with a name for his blog, U.C. Irvine professor David Eppstein interpreted his initials as the hexadecimal number oxDE, then converted the result to binary. 11011110 is the result. Anyone interested in computer science is sure to find Eppstein’s posts both entertaining and informative. He writes on just about everything, always from a computer science perspective. Recent articles include “The inbox of a triangle,” “An unflippable polygon,” and “More on uniqueness in Sudoku.”  

Academic Computing

Neil Brown, a computing education researcher at King’s College London, writes and publishes the popular computer science-themed blog Academic Computing. Brown writes mainly “essays and arguments about computing education,” with a few interesting outliers here and there. Recent blog posts include “While My Guitar Gently Beeps,” “Code highlighting: the lowlights,” and “What makes a [computing education] research paper?”

bit-player

Despite claiming to be the thoughts of an amateur on computation and mathematics, bit-player is actually authored by Brian Hayes, the one-time “Computing Science” columnist at American Scientist. Hayes’s posts are always based in computer science, yet cover such topics as biology, linguistics, neuroscience, and social sciences. Some of bit-player’s most recent posts include “April fool Redux,” “The Teetering Towers of Abstraction,” and “737: The MAX Mess.”  

Bits and Pieces 

Bits and Pieces is the blog of Harry Lewis, the Gordon McKay Professor of Computer Science at Harvard University. Though Bits and Pieces is mostly a personal blog with musings on a variety of subjects, Lewis frequently comments on the intersection between computer science and programming, and the academic, political, and business worlds. Recent posts include “A question unanswered in the Epstein report,” “The Wheaties box,” and “Let the snitching begin.” Bits and Pieces is a must-read for anyone interested in Harvard, especially. 

CodeWall 

CodeWall is the work of British web developer Dan Englishby. The blog features articles on such topics as JavaScript, HTML/CSS, and PHP, among other things. Just about everything is written as a useful, in-depth tutorial that will appeal to both experienced coders and those who are just learning. Recent posts include “PHP Arrays Explained,” “Select All Checkboxes with JQuery,” and “Building Data Visualizations in PowerPoint Using Python.”

Coding Horror
