Entangled ways of product development in the area of cybersecurity #3 - LogMan.io

At that time I lived in Prague for a short time, which is not a very friendly place to live, but it allowed me to go to the office almost every day. A bigger surprise awaited Vlaďka and Aleš when I told them that I was going to move to a house almost eighty kilometres from the office and that I would need to be mainly at the home office.

Binary distributions of OpenSSL static libraries

The official source of OpenSSL software is the OpenSSL website. One can download OpenSSL source codes archives and compile them for a given platform. The compilation work can sometimes be quite tedious, especially for exotic platforms. We, at TeskaLabs, set up this page because we frequently compile OpenSSL for various platforms for our internal purposes and this may save some time to other developers.

Software architect's point of view: Why use SeaCat

I've recently received an interesting question from one software architect: Why should he consider embedding SeaCat in his intended mobile application? This turned into a detailed discussion and I realised that not every benefit of SeaCat technology is apparent at first glance. Let me discuss the most common challenges of a software developer in the area of secure mobile communication and the way SeaCat helps to resolve them. The initial impulse for building SeaCat was actually out of frustration of repeating development challenges linked with implementation of secure mobile application communication. So let's talk about the most common challenges and how SeaCat address them.
