Classic Computer Science Problems in Python

Posted on October 27, 2019 | 2 comments

I really enjoyed Classic Computer Science Problems in Python by David Kopec. It covers many different problems I hadn’t read detailed explanations of before. For example: neural networks, constraint-satisfaction problems, genetic algorithms and the minimax algorithm. Unlike many other books on algorithms and programming problems, this one builds up complete (but small) programs that are easy to explore on your own.

When TDD Is Not a Good Fit

Posted on September 29, 2019 | 11 comments

I like to use Test-Driven Development (TDD) when coding. However, in some circumstances, TDD is more of a hinderance than a help. This happens when how to solve the problem is not clear. Then it is better to first write a solution and evaluate if it solves the problem. Writing tests only makes sense after the solution is viable. Continue reading →

Book review: Accelerate

Posted on May 26, 2019 | 2 comments

The book Accelerate details the findings of four years of research on how DevOps affects various outcomes, such as software delivery tempo and stability, as well as the organizations’ profitability and market share. DevOps in this context means things like continuous delivery, automated tests, trunk-based development, and proactive monitoring of system health. It is quite clear that DevOps practices bring lots of benefits to organizations adopting them. The research findings are also in line with my own experience of DevOps.

Programming: Math or Writing?

Posted on March 30, 2019 | 4 comments

Is programming like math, or is it like writing? I think there are elements of both in it, even though programming is a discipline of its own. Nevertheless, it is interesting to think about what aspects are like math, and what aspects are like writing. Maybe it will even lead to a better understanding of what programming is.

6 Git Aha Moments

Posted on June 25, 2018 | 24 comments

When I switched jobs four years ago, I went from using subversion (svn) to using git as the version control system. Even though I am a pretty quick learner, it took me a quite a while to really understand git. I read a lot on how git works, but even so, I didn’t always realize what the implications were for how to use git. Here are six big “aha moments” I had on how to use git. Continue reading →

Exercises in Programming Style

Posted on March 13, 2018 | 6 comments

In the book club at work, we recently finished reading Exercises in Programming Style by Cristina Videira Lopes. The book consists of a simple program implemented in 33 different programming styles. It is a great way of showing the different styles, and the book was quite popular in the book club. The book is relatively new (it was published in 2014), and I don’t think it is as well-known as it deserves to be. So here is a summary and review of it. Continue reading →
