Frustration, anger, resentment and disappointment are just a couple of feelings that people in line to do the Swedish Scholastic Aptitude Test (Högskoleprovet) are feeling.

This year is special, there are less than 30.000 seats to do the test which greatly outweighs the number of people that want to do it. The Swedish Council for Higher Education (Universitets- och högskolerådet) knew upfront that the pressure on the signup would be high and took action for the signup system not to collapse.

The solution the council implemented is based on a queueing product. It throttles access to a page and puts…


When the car became readily available the amount of traffic accidents and deaths started rising. This was only a natural consequence of more cars in movement. Yet since 1965, that was the year with most traffic deaths in Sweden, the numbers have been in decline — even though the number of cars is on the rise. This is not by chance — it’s by design.

Today we see more software being used than ever before and it’s steadily on the rise. More interactions and transactions are done digitally than ever before and we see a steady rise in security breaches.

Today, we are closer to living in a sci-fi novel than ever before, technology has infiltrated our everyday lives and we’ve grown more dependent on it than ever before. We stand here today on the verge of a new era. We have been put here not by will but by necessity yet the things we learnt and experienced will stick with us forever.

I believe it is pointless to…


In the context of the COVID-19 pandemic we are all faced with a very real and very new situation — we can’t be with our teams in the same way we used to. So what does it mean to be agile in a distributed or remote scenario?

This question is nothing new, we as an industry have been struggling with “the software crisis” for decades. We have a shortness of talent which means we need to distribute work to wherever we can find the right people. …


It’s been an interesting week in IT and security here in Sweden. On Monday the Swedish publication Computer Sweden exposed that 2,7 million recorded phone calls roughly 170 000 hours from the Swedish Health Care Guide 1177 where completely exposed on the internet. These were calls made by people about their medical conditions containing sensitive and personal information about the individual or their children.

This in itself is catastrophic — but what is worse is that this is not the first time we see something like this and it is, most likely, not the last. In this case it’s also…


It’s 2015 and I find myself in a car with Sebastian. This time he is not trying to set me on fire. As we neared Malmö I was attempting to use half of my brain to compose a tweet and the other half to listen to the cliff notes of Sebastians talk. As a single threaded person neither was going very well.

Sebastian was on his way to share war-stories of being a technical tester with the next generation of testers at some form of education. I was mostly there because there was a promise of lunch involved.

We slowly…


Leetspeak is a conference by developers for developers. It’s an affordable, high-quality, community conference.

This year for Leetspeak we wanted to try something different with the theme. Because — let’s be honest — we as a community can sometimes get caught up in the latest and greatest and forget what is really important — getting things out the door.

As someone once said to me once:

“The code is not done until it is in production making me money”.

Granted that might be a bit harsh but there is definitely a point to it — we don’t write software…
