Die meisten dürfen es ja mitbekommen haben, Microsoft hat die neue Beta für den Internet Explorer 7 öffentlich zum Testen bereitgestellt. Was ja eigentlich klar war: er enthält noch Bugs.

Also stellt man sich die Frage, ob es nicht sinnvoll wäre, einen TestCase für Browser zu erstellen. Sinnvoll ist das nicht nur für die Browser-Hersteller, sondern auch für Webdesigner, denn diese müssen nicht ständig nach Bugs suchen (ist das jetzt ein Bug oder bin ich das).

Nachdem Jens Grochtdreis diesen Punkt angesprochen hat, hab ich mir mal Gedanken gemacht, wie das am besten zu erreichen wäre. Nach langem Überlegen bin ich der Meinung, dass es keine Möglichkeit gibt, so etwas sauber automatisiert aufzubauen:

• Auflistung von mehreren gleichen Bugs
• fehlerhafter Code kann nicht als Bug angesehen werden
• etc.

Also ist es meiner Meinung nach sinnvoll, hierfür eine Community zu verwenden. Die Mitglieder posten Bugs, Moderatoren prüfen diese. Und alle haben die Möglichkeit, über Bugs zu diskutieren. Also mal dem Strohhalm vorschlagen, was sie meinen. Ich hoffe, dass so etwas schnell aufgezogen werden kann.

OpenSource is a really nice idea and helps to program things much faster. They help you not do invent things, which are already invented. But for me, they are mostly just a method to lern new programming paradigmas. What’s really annoying me is the documentation.

For a programming project for letter recognition at my university, I want to use Torch3, a library for machine learning in c++. The tutorial shows, that the library is really interesting. But unfortunatelly, the documentation is not very good. Only the examples help a little bit to use the library.

What can we learn? If we want to publish an open source project, the documentation is very very important. If we want that many people use our library, this is nearly as important as the library itself.

Ok, let’s try to use the library….

Some time ago, I have written a short summary about fuzzy logic. I think, now is a good time to make this paper public, so everyone can read it and it’s possible to see how we can use it.

Fuzzy logic is a nice possibilty if we don’t want or we can’t devide the world into white and black. It’s used in many disciplines especially in neuro informatics, which is my favourite study direction.

So here is the paper about fuzzy logic (pdf, german). It was my first attempt in using latex. Today, I love it.

Jens Grochtdreis asks, if there are any test cases in the www. Because today, there are in every browser one or more bugs, such a testcase could help to solve problems. For software developer, it could help to fix the problems. For web designer, it could help to find answers, why something isn’t working as it should.

I think, that’s a really great idea! How often I was not amused about a bug especially in the Internet Explorer. If there will be a central place to look for bugs, I wouldn’t waste time in trying to find a solution.

So I hope, there will be a good testcase. If there is no one until now, perhaps I will help to build one.

There are a lot of HTML and XHTML courses online. Even CSS is reported and discussed at many websites. But what’s about PHP? I have just entered some search expressions in google to look for a good PHP course for a friend of mine. But unfortunatelly, I cannot find any.

So, I have decided to write a course in this blog. I think it’s a good possibility to show why PHP is my language of choice and to what a programmer has to look for.

The course will be written in this blog. (Nearly) Every day, I want to post some aspects of programming in PHP. It should be possible for everyone to learn PHP in this way. At each end, there will be some exercises to train, what we have learned.

[Update]

At php-q.net there seems to be a good tutorial, so I have not to do this again.
