Almost every non trivial application uses in some way a database. For many years this has been anyway Oracle, DB2 or MS-SQL-Server, depending mostly on the habits and on the religious orientation of the organization that developed or ran the application. These days all three are available for Linux and MS-Windows. DB2 is also available …
When comparing string, of course spaces count as well and they should count. To ignore them, we can normalize strings. Typical white space normalization includes the following (Perl regular expressions): /[ \t]+/ /g replace any sequence of tabs and spaces used to separate content by one space. /\r\n/\n/g replace carriage return + linefeed by linefeed …

I have visited Scala Exchange („#ScalaX“) in London on 2017-12-14 and 2017-12-15. It was great, better than 2015 in my opinion. In 2016 I missed Scala Exchange in favor of Clojure Exchange. This time there were really many talks about category theory and of course its application to Scala. Spark, Big Data and Slick were …

There is this so called „double brace“ pattern for initializing collection. We will see if it should be a pattern or an anti-pattern later on… The idea is that we should consider the whole initializion of a collection one big operation. In other languages we write something like [element1 element2 element3] or [element1, element2, element3] …

Some may have noticed, some not, but the landline telephony is actually being shut down in the next few years, if it has not happened already. This is done in Germany and in Switzerland and I assume other countries will follow or even do it earlier. In some countries and in some age groups the …

Most of us know ticket vending machines that are used for public transport. While people who often buy a similar ticket usually have no trouble using them, it can become quite hard for functions that we rarely use or for people who only rarely use the ticket vending machines. Why is it so hard to …

The WPA2 protocol has been compromised. The so called KRACK attack allows reading encrypted content. It was always a good idea to use encrypted communication on top of WPA2 for sensitive data, like https, ssh or a VPN. This practice has been recommended in this blog before, which was again inspired by what Bruce Schneier …
