API design is hard. Learn how Keygen handles API versioning, and how we make changes even when that means breaking things.

Anyone writing code professionally in December 2021 will remember the “fun” of the Log4J vulnerability. For those that weren’t - this was a critical security error that allowed attackers to run any code they wanted on your servers. The root cause was a logging library, Log4...

Eerder dit jaar spraken Kustaw Bessems en ik elkaar in een aflevering van de Volkskrant podcast ‘Stuurloos’ (reservelink). In een uitzending van meer dan een uur behandelden we waarom het zo moeilijk is voor de overheid en grote bedrijven om mensen te werven die ergens echt veel vanaf weten, en die mensen vervolgens ook te behouden. Ik had me gemeld bij ‘Stuurloos’ na het beluisteren van de zeer waardevolle eerdere aflevering Gevaarlijke combinatie: politici én ambtenaren zonder vakkennis met Geert-Jan Hamilton en Peter van Lieshout (artikel).

Learn how to safely upgrade your licensing integration from v1.0 to v1.1 of Keygen's API.

As presented on the 24th of May 2022 at the European Energy Law Seminar 2022 organized by the Dutch Energy Law Association (NeVER), in cooperation with the University of Groningen’s Centre of Energy Law and Sustainability and the University of Oslo’s Scandinavian Institute of Maritime Law So before we delve into the fascinating relation between cybersecurity and the worlds of oil, gas, energy and electricity, I need to introduce myself a bit.

My name is  Eric Migicovsky  and I love small phones. It’s weird because I am 6'6" but I never enjoyed using a large phone. I loved the Sony…

Hi everyone, A brief note, I’ve written a book, and the content is nearly done. You can read all about it here. The first 90% of the project went well, but I need (well paid) help with the remaining 90% to turn it into a decent book. This is a ‘for profit’ book, but it will be given away for free to schools, universities and readers/students unable to afford it. So there is a bit of feel-good factor involved.

In an earlier post I presented a naive model for estimating Dutch electrical solar power generation numbers. It turns out that the Dutch electrical power generation numbers are an even bigger mess than I appreciated. It appears that “everyone knows” that the numbers are confusing, incomplete and perhaps even wrong. But somehow this state of confusion isn’t written down anywhere. So I’ll give it a shot. A round of thanks to a small number of anonymous industry insiders that provided invaluable help!

Introducing a new, even easier way, to handle offline and air-gapped licensing with Keygen.

As part of my coping mechanisms, I like to make graphs of important things I worry about. Recently with the Russia-inflicted horrors in Ukraine, I’ve been looking at the torrent of Russian gas being bought by Europe. This turned into a live plot that shows just how much money we are sending to Russia. In that post, I also dwell on how we are using that gas to heat our houses and generate electricity.

The horrors of the Russian war on Ukraine continue unabated. Every eurocent we send to Russia is an intolerable assault on the senses. The world buys lots of things from Russia. For some of these, if Europe does not buy them, someone else will. But there is one major exception: natural gas. Over the past few weeks I’ve been automating graphs that show, on an hourly basis, just how much gas we buy from Russia:
