It was this typical clash of cultures when a real IT guy, scientist, mathematician or engineer joined a company and suddenly an office package had to be used. It could have been any of them, think LibreOffice or MS-Office, but there were some others, that have meanwhile lost relevance. We liked to use text files …

In SQL we often want to create or drop an object (TABLE, VIEW, SEQUENCE, INDEX, SYNONYM, DATABASE, USER, SCHEMA,….) Now we do not know if this thing exists or not. We would like to write scripts, that work in either case. So something like CREATE TABLE IF NOT EXISTS XYZ (…); or DROP TABLE IF …

Deutsch Serialization allows us to store objects in a lossless way or to transfer them over the network. This could be done before, but it was necessary to program the serialization mechanism, which was a lot of work. Of course, they were not yet called objects in those days… Java suddenly had such a serialization …
To be honest, what can be done with Python can also be done with Perl or Ruby. I am not working in areas, where there is much better library support for Python than for Perl or Ruby. And I like Perl and Ruby very much and I am somewhat skeptical about Python. But there are …

We use different file formats that are more or less tolerant to certain changes. Most well known is white space in text files. In some programming languages white space (space, newline, carriage return, form feed, tabulator, vertical tab) has no meaning, as long as any whitespace is present. Examples for this are Java, Perl, Lisp …

We often encounter nested loops, like for (i = 0; i < n; i++) { for (j = 0; j < m; j++) { doSomething(i, j); } } This can be nested to a few more levels without too much pain, as long as we observe that the number of iterations for each level need …

It is nice to write about positive things, how things have been done well, how they should be done well and how good we are and how good we could be if we were just applying the right technology and methodology and process and management… Tom Rocket Let’s leave that for today and write about …

It seems that Microsoft is buying Github for about 7.5 billion USD worth in their own stock. Is this a good thing or a bad thing? Probably no reason to celebrate, but Microsoft under Nadella seems to run a totally different strategy than Microsoft under Steve Ballmer. Selling licenses of MS-Windows and MS-Office is probably …

In 2018 I visited Scala Days in Berlin with this schedule. Other than in previous years I missed the opening keynote, which is traditionally on the evening before the main conference starts, because this is not so well compatible with my choice of traveling with a night train, especially because I did not want to …
Deutsch A lot of things in today’s IT landscape have been unified and interoperability is much better than 20 years ago. Some examples: Networking: Today networking is TCP/IP. Even the physical cables with RJ45/Ethernet and the wireless networks have been standardized and all kinds of devices can use the same networks. In the old days …
