50 topics for Jazz Interviews

February 12, 2011

Some days ago our band gathered in a small radio station’s studio to promote our latest CD. The show is called “Jazzerrimo“. There has been a great, relaxed and comfortable atmosphere with the show’s host Victor Bobeche, a very friendly guy, with a strong dedication to the music he’s featuring. But honestly, I’m glad it’s been only a tiny radio station and their radio waves barely reach areas outside its neighborhood in Madrid. I think we’ve not been able to successfully emphasize interesting and positive aspects of our music. Clearly our fault: we have little experience and practice in this kind of “promotion matters”. I think unfortunately a lot of jazz musicians face the same problem.

Lesson learned! You have to train to be a good interview partner! As a first steps I have analyzed some jazz podcast that I use to follow. I’ve put down some typical conversations topics – in a completely non-scientific and non-systematic matter, of course. Anyway, none of these should surprise you or make you stutter:

Relational Databases don’t deserve their name

February 5, 2011

Relational Databases (also refered to as Relational Database Management Systems–RDMS) are a class of databases that store data in different tables. Their name is derived from the fact that it is possible to reference a table in another one and thus establish relations.

How does that look like in practice? Let’s take the artist-album relation as an example. That’s a one-to-many relation because one artist can record several album. Typical RDMS handle that with ease, using a reference in album table back to an artist’s unique identifier.

Javascript, the language of Platonic Cavemen

December 23, 2010

Shadow of a mad programmer

At first sight, Javascript seems to be just another modern programming language. The name sounds like that of an old friend and its curly brackets and constructs like for, while, if etc. give you a warm comfortable feeling. You might have heard it is object-oriented, too.

In this article I’ll try to argue that this first impression might be misleading. Therefor please let me go back in time a bit… about 2400 years.

Platon’s Cave Metaphor

According to Greek philosopher Platon there is something higher than our material world. It’s the world of ideas. Objects in our world are just imperfect images of a corresponding idea.

To illustrate this thesis he introduces a metaphor. It depicts men chained to a cave’s floor and starring at a blank wall since their childhood. The only thing they see are shadows thrown on to the wall by real world objects. As their perception is limited to what they see on the wall, Platon’s cavemen take that world of shadows as their real world and they can’t imagine there could exist another world that is to a higher degree real.
