Blub Paradox

Ich habe da einen interessanten Artikel ueber das Blub Paradoxon gefunden.
Jenes besagt, das fast alle Programmierer der These zustimmen,
dass Programmiersprachen sich in ihrer "Macht" und Generalitaet unterscheiden, aber trotzdem
nicht bereit sind einzusehen, das andere Programmierespachen besser sind als die, die sie
habituell verwenden.
Verdeutlicht wird das am Beispieln eines eingefleischten "Blub" Programmierers.
"Blub" ist eine P.Sprache die im mittleren Bereich des Generalitaetskontinuums
liegt, das sich zwischen Maschinencode an einem Ende - und Lisp am anderen Ende
erstreckt.
Der Blub Programmierer kennt alle Sprachen, die schwaecher als Blub sind, und fragt sich,
wie man bloss ohne eine Feature "x" vernuenftig programmieren kann(- natuerlich verfuegt Blub ueber x).
Ausserdem findet er, dass Blub alle Features hat die er braucht, und ihm erscheinen features in
"hoeheren" Sprachen als verwirrend und unnoetig. Er denkt in Blub, und Blub ist sein Horizont -
und alle Probleme die er fuer loesungswuerdig befindet, sind in Blub loesbar!

Lazy Evaluation(there be dragons and basement cats)

Lazy Evaluation and "undefined" I am on the road to being a haskell programmer, and it still is a long way to go. Yesterday I had some nice guys from #haskell explain to me lazy evaluation. Take a look at this code: Prelude> let x = undefined in "hello world" "hello world" Prelude> Because of Haskells lazyness, x will not be evaluated because it is not used, hence undefined will not be evaluated and no exception will occur. The evaluation of "undefined" will result in a runtime exception: Prelude> undefined *** Exception: Prelude.undefined Prelude> Strictness Strictness means that the result of a function is undefined, if one of the arguments, the function is applied to, is undefined. Classical programming languages are strict. The following example in Java will demonstrate this. When the programm is run, it will throw a RuntimeException, although the variable "evilX" is never actually used, strictness requires that all argu

Learning Haskell, functional music

As you might have realized, I started to learn Haskell. One of the most fun things to do in any programming language is creating some kind of audible side effects with a program. Already back in the days when I started programming, I always played around with audio when toying around with a new language. I have found a wonderful set of lecture slides about haskell and multimedia programming, called school of expression. Inspired by the slides about functional music I implemented a little song. Ahh ... and yes it is intended to sound slightly strange . I used the synthesis toolkit to transform the music to real noise, simply by piping skini message to std-out. I used this command line to achieve the results audible in the table: sven@hhi1214a:~/Mukke$ ghc -o test1 test1.hs && ./test1 | stk-demo Plucked -n 16 -or -ip Sound samples: Plucked play Clarinet play Whistle(attention very crazy!) play As always the source... stueck = anfang :+: mitte :+: ende anfang = groovy :+: (Trans

The purpose of the MOCK

In response to a much nicer blog entry, that can be found here . There are actually several distinct "tests" that make up usual unit tests, among them two that really do stand out: one kind of testing to test method flows, one to test some sort of computation. Mock objects are for the purpose of testing method flows. A method flow is a series of message transmissions to dependent objects. The control flow logic inside the method(the ifs and whiles) will alter the flow in repsonse to the parameters of the method call parameters passed by calling the method under test, depending on the state of the object that contains the method under test and the return values of the external method calls(aka responses to the messages sent). There should be one test method for every branch of an if statement, and usuale some sort of mock control objects in the mock framework will handle loop checking. BTW: I partly use message transmission instead of method invocation to include other kind
