Phun with Physics

Wednesday, January 21. 2009

While browsing on OpenGL.org, I found a really nice educational (?) 2D physics simulator called Phun. The physics engine is a commercial multibody simulator, which seems to be new in the physics scene (at least I never heard of AgX before).

And now, don't waste your time on my blog, and Grab Phun here.

Cygwin + Avira = Nogo

Monday, June 4. 2007
I have been using Microsoft Windows as my primary operating system since Windows 95, but I have always prefered the NT line for its superior stability and security (if configured right). I always use a normal user account for my daily work (not even a Power User account) and the Administrator account for installing software or changing the computer configuration. Plus I do not opene every attachment I get in all those virus mails :-) This way I have been virus free for about 10 years.

But I thought it could be a nice idea to install an AntiVirus program for increased safety. I decided to use Avira, simply because it has a free version for home users and I didn't hear anything bad about it. After some time I even decided to buy the premium edition that has some additional features, and I thought that I was happy.

Then I found out that my notebook seemed to have a hardware defect. When I tried to build a large "make" based project within Cygwin, the korn shell would stall after some minutes and I could not kill it any more. First I suspected bad memory, so I ran some memory tests - no result. So I was thinking that the CPU could have suffered to much and could be broken. I started to look around for a new notebook, although I really didn't want to buy a new one, as my old one was still good enough for me (if it worked).

After a week, I thought that maybe the crashes of the shell could be a software problem. So I uninstalled some applications. No change at all - unless I uninstalled the Avira AntiVirus package. Simply disabling the virus scanner did not make any change, but after I uninstalled the whole package, I could compile again! After some hours of successful compilation I searched google for "Cygwin Avira" - bingo, there are some well-known problems.

Conclusion: If you want to use Cygwin, don't even install Avira, or you might suffer.

The Tulse Luper Journey

Thursday, January 4. 2007
I am a big fan of the english avantgarde director Peter Greenaway, who made the films (among many others)

Now Peter Greenaway has an exciting new project called The Tulse Luper Journey, which is more than only a film. It is a story about a fictive man called Tulse Luper (who already appeared in some of Greenaways previous works), who was imprisoned for his whole life - mistaken for someone important, a spy, a lover, an artist, a writer and an observer. Luper has packed a total of 92 suitcases in his life reflecting his subjective view of the history of the 20th century. The complete project includes three feature films, a TV series, 92 DVDs, CD-ROMs, and books.

The Tulse Luper Journey also contains an online game which is still going. You can win a Tulse Luper DVD box and a journey round the world.

Need an Old Version of a Software?

Sunday, January 15. 2006
By chance I stumbeled over a very useful website offering old versions of programs for download. You might ask why some people might prefer not to use the latest sotware? Well, not every version upgrade automatically means better software. Plus modern software tends to be heavywight with tons of options and unnecessary bloat - while earlier versions of the same program were fast, easy to use and small.

And especially web-designers might want to take a look at that site, because there are tons of old browsers available. These form an important tool for all HTML-people in order to verify that their pages can be viewed not only on a broad base of different browsers, but also on different versions of the same browser.

So, here is the link: http://www.oldversion.com/ to that important site.

Reduce Ads with Firefox

Thursday, September 15. 2005
Yesterday while I was browsing through the internet, it finally happened after a visit to Spiegel Online, the online version of a popular German news magazine: I couldn't stand the advertising banners any more, they were simply eating too much space on the screen and downgraded the experience by a massive amount.

So I googled arount and in some seconds, I found two very useful tools for Firefox: The Adblock Project which is a simple but powerful adblocker for the Firefox browser and the Adblock Filterset.G Updater, which fetches the newest filterset from the internet.

After installing these two tools (which are installed on a per-user basis), most of the disturbing ads disappeared from the webpages - and pages load much faster, (although I already have a 6 MBit connection, but it seems that many ad-servers simply can't provide their unwanted content fast enough).

Status update

Wednesday, June 15. 2005
I really feel somewhat bad that I didn't find the time to post a new entry for over a month now. But I am really busy at the moment.

First of all I currently work for a small company which is specialised in creating software for high-end visualisation and VR systems. Unfortunately I am not allowed to tell much about my work there.

Second I have to do a lot of work at home as I am working as a freelancer at the moment. I am preparing a new webpage for my one-man company dimajix and I have to produce a lot of paper-stuff and try to get new customers. Fortunately at least my new webpage will be finished soon and it will have a far more professional look-and-feel.

Last my girl-friend (or should I say now fiancee) and me plan to marry in september this year, here again we already have to plan a lot, make the invitations, care about the ceremony etc.

Due to all these activities (plus I try to get on my bike when I find some time) unfortunately I did not find much time for working on Project Magnum, for making up new OpenGL demos or simply to post a new entry to my blog. But as some jobs finally get done, I hope that I will find some more time again soon.
