Foreigners make better programmers

We have recently been recruiting a couple of new programmers at Neurobat. This time we submitted the candidates to an online programming test, which consists of a couple of (relatively) simple programming assignments to be completed in a given time. Out of about 100 applications, 34 were given this test. I have collected the data […]

Phileas Fogg on Agile Project Management

I just finished reading Jules Verne’s Around The World In 80 Days, which I had never read before. It’s a great read and I highly recommend it to children and adults alike. But half-way through the book I realized there’s more to this book than a nice tale of adventure. This book is a complete […]

ScrumMaster no more

The first thing we did this week was to hold a sprint retrospective. And one of the first things we decided was that I should step down as ScrumMaster. Which I gladly did. In recent months I had been travelling more and more, attending more and more meetings, and it had become clear that there […]

Standup meetings are not diaries

Very often I hear scrum standup meetings go something like this: Fred: “yesterday I used Git bisect to find out where and when bug #1234 was first introduced. That didn’t work so I created a new unit test to reproduce it and asked Alice what the naming convention for unit tests was and…“ Stop. Do […]

Selenium script to reset a ZyXEL NBG4115 4G Router

The ZyXEL NBG4115 is a small, cheap 3G router that can be used to build a wireless network where there is no access point available. You plug one of those 3G dongles into it, enter the PIN number, and you have a local access point in the middle of nowhere. At Neurobat we use these […]

Automatic data collection without FTP

I haven’t written anything in a while, so I thought I might begin by sharing some ideas on how we collect test site data at Neurobat without using FTP. We have a Dropbox Teams account, which gives us about north of 1 TB of storage. The idea is to install Dropbox on each netbook that […]

Pomodoro + Workrave = Well-being

I’ve been a big fan of the Pomodoro Technique for almost a year now. No, I don’t go as far as actually having a ticking timer in my office in front of my co-workers, and I don’t necessarily plan the day in advance, but I do try to break up my work in 25-min iterations […]

Converting Sweave/R plots for inclusion in Word/OpenOffice

Just a quick note to myself: When you use Sweave and produce high-quality plots in both EPS and PDF formats, you sometimes want to include them in Word or OpenOffice documents. You can’t directly include PDF files, and you can only include EPS files when they have a preview, which Sweave will not do by […]

Polyphasic sleep

Wikipedia defines polyphasic sleep as the practice of sleeping multiple times in a 24-hour period. Proponents of this practice argue that it results in a much reduced total sleep requirement, sometimes as little as two hours total sleep per day. This concept immediately caught my interest when I heard about it, as it should interest […]
