“This is a fantastic book that is also available in print. It covers everything, from installing Python and the language’s syntax, right up to web services and unit testing. This is a good book to learn from, but it’s also excellent to use a reference. I frequently find myself visiting the site! If you only read one book on this list make it this one.”

“Unix is a user hostile operating system”

I found the almost complete “Computer Chronicles” recordings on archive.org – and boy this is fun!

I picked some episodes and found very interesting things – like this particular episode from 1985. It’s about Unix and obviously one of the presenters has his very own opinion about Unix.

Spacetime Math tools

If you searching a tool for Windows, Linux, OSX and your windows mobile device…you may want to take a look at this:

“SpaceTime 3.0 by SpaceTime Mathematics is a revolution in mathematics software with 2D, 3D, and time graphing with MobileCAS® for algebra and calculus. With features only available in Mathematica and MATLAB, SpaceTime is the most powerful cross-platform mathematics software ever developed for computers and mobile devices.

turn new pictures into old ones…the Bakumatsu picture generator

“Bakumatsu were the final years of the Edo period in Japan. It was a turning point in Japanese history as it was the end of the period of isolation in Japan. The feudal way of governing was coming to an end, and the start of the Meiji government, which would later take Japan to the world power status.”

This is a very cool picture effect free to use which turns this:

futuristic user interfaces…

This is a very impressive overview of new user interface ideas. It’s a fact that we need new userinterfaces for all kinds of use cases – and as it turns out there are unbelievable cool things going on in the UI research.

Good user interfaces are crucial for good user experience. It doesn’t matter how good a technology is — if we, designers, don’t manage to make user interface as intuitive and attractive as possible, the technology will hardly reach a breakthrough. To gain the interest in a new product or technology, users need to understand its advantages or find themselves impressed or involved.

And here is where creative ideas and unusual interface approaches become important. Innovative doesn’t mean usable and usable hardly means innovative. As usual, it’s necessary to find an optimal trade-off. And some user interfaces manage to achieve just that.”

how to create your own photosynth

Photosynth is publicly available and it’s time to give it a try and play with the technology. Before starting you should be aware of some facts about the public photosynth technology-preview:

  1. all synths are uploaded and only available online (broadband needed)
  2. all synths are public, everyone can access them
  3. the synther tool runs only on Windows
  4. you’ll need a Live ID

When everything is checked you can go and upload up to 20 Gbytes of image data – my test synth takes up 200 Mbytes of the available space – so you have plenty of space to play with.

To start just install the photosynth application to view – and click “create” on the website. After the obligatory login you immediately can upload your pictures. Give it a name, ssome tags and a license and select your pictures.

Your pictures should show the same scene from different perspectives – photosynth is all about matching perspectives. After clicking on “Synth” the process starts.

And after a surprisingly short period of time your synth is done. Click on “View Synth” and you’re taken back to the website and you can browse your synth. That’s it – easy!

Fixing the bad bad mouse acceleration in Mac OS X

I finally found a fix for the unspeakable mouse acceleration problem I have with MacOS X. It’s just a fact that Apple seems to have no idea how to do the mouse handling. Some people say it’s the mouse acceleration curve that apple got wrong:

“As wonderful as Mac OS X is, it has a grave defect that can have an immediate adverse impact on the computer’s usability: the way it translates mouse motion into pointer movement. For many users, moving the mouse feels unnatural because of the peculiar way that Mac OS X performs that translation. In industry parlance, the translation is called the “mouse acceleration curve.” What is a mouse acceleration curve, and how is its implementation problematic under Mac OS X?”

It’s a problem I can live with but I am not happy. With Panther and Tiger I had a solution called MacMiceCommand. But with Leopard this solution stopped working and until I found this:

“This is a GUI version of Richard Bentley’s MouseFix. (i)MouseFix is a very simple program that will allow you to regain control of the mouse acceleration in Mac OS X. Both this web page and the program copies large parts from MouseFix because he says: “feel free to take the code and wrap a nice interface round it. Be nice and make it free for everyone to use though :-)””
