Video series about a complete Music Production with Muse and Ardour

I created an in-depth tutorial about creating a complete cover song from the MIDI file to the final mastered song.

Creating a Drumgizmo kit from existing samples

This post is about the Drumgizmo plugin I use often under Linux as a drum plugin. It has some free drumkits on the homepage to download, but I also wanted to create a drumkit out of samples I already had. I bought a commercial multi-velocity sampled drum library from drumdrops (the Mapex Heavy Rock Kit to be precise), which I really like, and created a drumgizmo patch for it. You can hear drumgizmo with this kit in action e.g. here:

The Rise and Fall of Ken Wilber?

In this post I take a look at some critique from Mark Manson (this Article). I agree with a lot of what he says, but about some things I have a quite different view. This is strictly my personal opinion about a topic, which some see as the “fall” of Ken Wilber, which I simply don’t see this way. Ok, let’s start…

A first thing that comes into mind is that in this whole article Mark always refers to Version 4 (Wilber-IV) and not one single time to Wilber-V, which is the current version. Actually, this is done by a lot of critics. This is quite fundamental as Wilber-I to Wilber-IV concentrate more on ontological issues (where and how objects are), whereas Wilber-V concentrates on views and perspectives (a more epistemological variant if you like). This renders quite some critiques obsolete. But this is not the main point I want to highlight.

Ein Blick auf Spirituelle Methoden

Nachdem ich im letzten Artikel auf Entwicklungsstufen eingegangen bin (siehe hier), haben sich einige Fragen zu spirituellen Methoden ergeben, wie z.B.:

Werden bestimmte Praktiken nur auf bestimmten Stufen verwendet, z.B. ist jeder Schamanismus Magenta?

Was ist mit spiritueller Entwicklung (durch Einweihungen, Rituale etc)?

Was ist Spiritualität überhaupt?

Um darauf einzugehen, sind auch hier einige Hintergrundinfos notewendig.

Ist Religion wirklich so schlimm?

(English version is here)

Kurze Antwort: Ja. Und nein.

Für die (sehr) lange Antwort lesen Sie bitte weiter.

Ich wollte diesen Artikel nicht schreiben, aber wegen der jüngsten Terroranschläge in Paris habe ich mich dazu genötigt gefühlt. Eine Menge Scheiße passiert gerade da draußen. Fundamentalisten nutzen die Religion um ihre eigene Weltsicht durchzusetzen (die natürlich die gewaltsame Entfernung von anders denkenden Menschen enthält), Atheisten scherzen oft über Religionen und belächeln religiöse Ansichten oft als dumm, Diskussionen über die Umkehr der Trennung von Kirche und Staat ( zB in den USA), Menschen, die sich aus religiösen Gründen weigern, Hochzeitsurkunden für Gleichgeschlechtliche herauszugeben (gegen das Gesetz), Diskussionen über Frauen, Abtreibung, Zölibat und “Werte der Familie”, “gut” und “schlecht”, große Widersprüche über das, was in den “heiligen” Schriften steht und was die Leute, die sagen, danach zu handeln, wirklich tun etc. Machtmissbrauch, Kindesmissbrauch, Überkontrolle, Patriarchismus, Unterdrückung, Aberglaube, Kreationismus, was Sie wollen, alles, was” schlecht “ist kommt irgendwie in den Religionen vor.

So auf den ersten Blick gibt es da nicht wirklich viel positive Dinge. Auch auf dem zweiten Blick ist es immer noch sehr schlimm. Also lassen Sie uns ein bisschen tiefer graben und hinter einige der Mechanismen in Religionen blicken. Vielleicht sind wir dann in der Lage, ein bisschen mehr zu sehen, nicht alles in einen Topf zu werfen, aufzukochen und dann dieses giftigen Mischmasch in Menschen zu füllen, nur um sich besser zu fühlen, als diese bedauernswerten fehlgeleiteten Kreaturen, mit denen wir Diskussionen führen.

Is Religion really that bad?

(Find the german version: here)

Short answer: Yes. And No.

For the (very) long answer please continue reading.

I didn’t want to write this article, but because of the recent terrorist attack in Paris I think I have to. There is a lot of sh*t happening out there. Fundamentalists use religion to implement their own world view (which of course includes the forceful removal of other-thinking people), atheists often joke about religions and do present religious views often as stupid, discussions about reversing the dividing of church and state are happening (e.g. in the US), people refusing to follow the law in giving gay marriage licenses because of religion, discussions about women, abortion, celibate and “family values”, “good” and “bad”, big contradictions about what’s written in “holy” texts and what people who say to follow them really do etc. Power misuse, child abuse, control, patriarchism, oppression, suppression, superstition, creationism,  whatever you like, everything “bad” is somehow present in religions.

So on the first look, there are not really much positive things in there. Even on the second look it’s still very bad. So let’s get a bit deeper and get behind some of the mechanisms in religions. Maybe then we will be able to differentiate a bit better instead of throwing all into the same pot, cook it up and then feed this poisonous mish-mash into people just to be able to feel better than these pitiable misdirected creatures we are discussing with.

Back from ICFP and CUFP

Back from my first ICFP and CUFP, where I had my first talk in the functional languages domain. Here is a link to the recorded talks, mine was “Haskell in the Mission Control Domain”:

Unfortunately, I could not find the recording from Björn’s talk right after me (Edit: Björn sent me a link, here is it:

It was a very good experience and also quite impressive, to see all the creme-de-la-creme from the Haskell community in one place! Also it was nice to get an association from names to actual faces.

Architecture of a Real World Haskell Application part II

OK, did take some time since the last post, but I am really busy now.

Last time we looked at the general structure of the application in terms of threads and model/interface separation. For this post, I want to write a little bit about the protocol handling and parsing and how it evolved. While this is not the most central part of the application, it is the oldest and therefore I think good to show some historical development.

Ok, so the tool began as a command line application which could only receive telecommands and send back correct responses (which on itself is not as simple as it sounds). Also at that point in time I just more or less started learning Haskell while my main language at that time was C++, so of course the first solution was a lot C++ like. So let’s see how it goes.

Architecture of a Real World Haskell Application

There were numerous posts on reddit, SO and the like which were asking for how to architect real world Haskell applications. Well, this is my go at it for an in-house testing tool which is used extensively. I would not claim myself an advanced Haskeller, some of the code is probably not idiomatic Haskell (and also some parts are really, ah well, horrible), it’s (by it’s nature) very stateful (read: imperative), BUT… it works. It even worked out better than I thought initially…

How it came to this…

I am working in the space domain and I am mostly concerned with mission control systems, especially the ones from the ESA (European Space Agency) named SCOS-2000. What we needed was a tool to be able to test certain new features implemented in the mission control system with a closed-loop test. The standard tools that come with SCOS are quite limited (and buggy) and written quite verbosely in C++. So why not try to create one in Haskell?
