Secure by Design

Posted on March 22, 2020 | 4 comments

I really like Secure by Design. The key idea is that there is a big overlap between secure code and good software design. Code that is strict, clear and focused will be easier to reason about, and will have fewer bugs. This in turn makes it less vulnerable to attacks. This is easy to say, but Secure by Design is full of techniques for how to actually do this. Here are the ideas from the book that I liked the most.

Grokking Deep Learning

Posted on January 4, 2020 | 1 comment

In the book club at work, I just finished reading Grokking Deep Learning by Andrew Trask. It is an introduction to deep learning, but there are some problems. It spends a lot of pages on the basics, and in the end moves on to some fairly advanced topics. It is also contains many small and irritating mistakes. However, it does have some great insights into deep learning. Continue reading →

EuroSTAR Testing Conference Prague 2019

Posted on December 8, 2019 | Leave a comment

A few weeks ago I spoke at the EuroSTAR software testing conference in Prague. The conference had one and a half days of tutorials, followed by two and a half days of talks. Around a thousand people attended. I was impressed by the sense of community and by the number of activities offered. For climate reasons, I chose to travel there and back by train instead of flying.

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 →

Recruiting Software Developers – Checking Out a Company

Posted on September 15, 2019 | 6 comments

I often get contacted by recruiters asking if I am interested in changing company. Even if I am happy where I am, I briefly check out companies I have not heard of before. One reason is that you never know, maybe the new company is a fantastic opportunity that really is interesting to me. Another reason is that I don’t know how things will change – maybe I will want to change in a year’s time or so. These are the things I check when I am trying to evaluate a company I haven’t come across before.
