January 22, 2013. There are many reasons to extract methods in old legacy code.  Sometimes you just see a small piece of cohesive code and you ask yourself whether you can name it.  If you can, extracting that code to a method is often a decent thing to do.   . In the following code, its easy to see that the while loop could be extracted into a simple method that forms a vector from the lines that we read from a file.  Its a decent extraction, but is it high value? Lets look a little closer. When I talk ...

Laquo; March 2013. July 2013 ». June 17, 2013. Avoid Null Checks by Replacing Finders with Tellers. One of my pet peeves in programming is null checks.  Many codebases are littered with them and, as a result they are often very hard to understand. Do we really need to retrieve or find objects in our programs? The other day, I saw this example on StackOverflow:. Person person = dataSource.getPersonById(personId); if (person! Function would simply do nothing, and the. Yes, would could do that, but it is a ...

Michael Feathers: Design and Testing

November 05, 2013. Control structures have been around nearly as long as programming but its hard for me to see them as more than an annoyance.  Over and over again, I find that better code has fewer if-statements, fewer switches, and fewer loops.  Often this happens because developers are using languages with better abstractions.  They arent consciously trying to avoid control structures but they do. .

Agile & Gamification talk. Posted by Logi Helgu. On Feb 6, 2015. I gave a talk at UTMessan. I asked a good friend that attended what he though and he was worried the first moments but then he said I pulled if off. And I was a bit worried since I had been told I could walk around but there was only the mike on the lectern so I was pretty immobilised and did have to skip some parts that I had planned. It’s really great they now have video recording of all the talks. 8230;a word I really like =). When my ol...
