It seems that the parts of the source code of Apple’s iOS 9 have leaked via github. They might have been removed from there, while you are reading this, but probably they will be passed around in the internet anyway. Some sources say that this is a risk to security. It might be, but in …

Java uses a nice pragmatic file format for simple configuration tasks and for internationalization of applications. It is called Java properties file or simply „.properties file“. It contains simple key value pairs. For most configuration task this is useful and easy to read and edit. Nested configurations can be expressed by simple using dots („.“) …

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.
