Forza Motorsport … a trip to New York

I made a little movie while I played Forza Motorsport … I have to play with my video captureing setup, because the quality could be better… but you will get a good impression how great this game is:

Forza Motorsport for the XBOX

In only a few days you can buy the most realistic and fantastic looking racing simulation for your XBOX. It’s called Forza Motorsport and is there to beat Gran Turismo 4.
I had the chance to play a little bit with it…and it’s insanely great! More than 50 cars. Dozens of tracks. And a realistic driving model I never experienced before.

Here are some ingame screenshots to tease you for the 3rd May:

I strongly recommend buying this game!

HDTV…you don’t have enough cpu power…

It’s great that more and more movies are broadcasted in HDTV. But it’s disappointing how much CPU power you need to get smooth video playback. Especially when it’s MPEG4 and not MPEG2.

This graph shows it: a 2.8 Ghz Pentium 4 is not really enough to handle high quality MPEG4 compressed HDTV. Almost 50 percent CPU usage when playing a 720p movie… don’t expect 1080i/p to run fluently…. this sucks.

The Premiere of “OPERation Rossini”

reply2all VJ Justus Rogman wrote about the premiere of “OPERation Rossini” in which he took part in:

“The premiere of “OPERation Rossini” was a complete success. Endless applause from a nearly sold out audimax took alot of load off our shoulders. Everything went well, just a small softwarecrash, but nobody noticed that and I was there for this emergency case and calmed down everybody so we could continue as nothing would have happened. First reactions from students on the opera & our visuals were positive after the first act so that we could do our job in second act a little bit more relaxed 🙂

It was just great!! They even forced me to come on stage while applause, so it’s me in background on the very right of following pic. But the applause of course is due to the actors infront. They really earned it! Like the orchestra. Was a great performance, especially in this cultural less-developed town :-p…”

Opportunity stuck in martian sand

Bad news for all the mars rover fans:

“A note to all you Opportunity fans: Get used to the current scenery, because we’re going to be here awhile,” said Steve Squyres, lead scientist on the Mars Exploration Rover effort at Cornell University in Ithaca, New York. “We are very optimistic that we’ll be able to get out of here, but we’re really going to take our time doing it.”

So let’s hope the best for the little rover.

Actually it’s great to see both rovers in good health so far. Remember: Officially their mission is over since more than a year…

free technical eBooks for your pleasure

It’s quite a time since I found this website where you can download several technical eBooks for free. One very interesting eBook is this:

A Programmer’s Guide to the Mind

“We will try to explain how the mind works, and we will also show how a person can make it operate more effectively. If we compare the task of developing the mind to that of taking a journey, then this volume could be described as a combination road map and tourist guide. While there are many similarities between a brain and an electronic computer, there are also several factors which make the human ‘computer’ unique: First of all, it is rather large. The electronic chips which are contained in the computers of the 1990s are constructed from flat little squares of silicon, no bigger than postage stamps. In contrast, the human thinking apparatus is a three pound, three-dimensional, solid chunk of neurons and interconnections. The average human brain contains about one hundred billion neurons and around one hundred trillion connections. Compare this to today’s computer chip with its total of about ten million transistors, and you can understand why, at present, we have about sufficient technology to simulate the brain of a slug.”

Fileserver malfunction

Why does hardware always break when you don’t have the time to fix it… but this time I had to fix it to continue to work…

Several Hard Resets because of defective RAM…and now the server is back online with half of it’s RAM…I’ll have to wait till monday to get new RAM… ;-(


while you wait for Star Wars Episode 3

This is the best Fan movie I’ve ever seen. So don’t miss it. You can download the “small” version (approx. 250 Mbyte) or the big DVD version which is 3.5 GByte.

“”Revelations” is a non-profit Star Wars fan film that was shot within the Northern Virginia, Maryland and Washington DC Metro Area. “Revelations” is made possible through a combined effort of artists, fans and the local film industry. Everyone who has worked on “Revelations” is a volunteer. No one is paid to make this film. Panic Struck Productions set out to produce their first independent film with a very small budget and the result is “Revelations””

accepting the challenge: developing a server based multi instant messaging client

I’ve written about my views and demands on the future Instant Messaging Client world several times. It’s a fact for me that the common Instant Messenger protocols and applications are not suitable for my needs. Maybe I represent the power-user group, maybe not. But without doubt the limits of ICQ and MSN are reached.

1. The Problem

Every available Instant Messaging protocol was designed to be used by one user at a time on one machine at a time. Since mobility is becoming more important these days slowly but surely everybody will reach this protocol given limit of one login at a time.

For example: When you log into ICQ on one machine. And then on your smartphone you do the same. Only the last client that logged into ICQ stays logged in. But why? Because the protocol and the server infrastructure is not designed to handle multiple logins.

2. The Goals

The goals are:

  1. design a comprehensive architecture to extend given instant messaging protocols (ICQ,MSN,…) with multi client capabilities

  2. implement the architecture platform independent

  3. create a specialised platform independent client to make it feel good (*g*)

3. The Team

Daniel “bietiekay” Kirstenpfad,
Markus “namenlos” Brückner,

If you want to join us. Feel free to mail.

4. The Architecture

I told namenlos about my problems with the instant messaging world during a dinner last week. And he came up with several great ideas. We took the chance, went to the office and started the brainstorming.

First we looked at all the protocols once again. And Jabber seemed to provide a quite good base for further thinking. But there was another idea. More simple. Maybe even easier to implement.

4.1 Plan A

in few words:

  • take Jabber as initial point
  • create some kind of Jabber “NAT” / Jabber Proxy which represents a Jabber client to the rest of the Jabber Network

we scribbled it on the whiteboard:

4.2 Plan B

The second plan is based on the IRC (Internet Relay Chat) idea which is described in RFC1459. Namenlos had the idea we could take a standard IRC Server and implement the Instant Messaging Protocols like ICQ,MSN,… as Modules.

After some brainstorming we realised that it should be possible to map all the Instant Messaging Features like Buddy-List, Chat, Chat-Conference, Filetransfer,… to the IRC idea. Query for Chatting, Channels represent the Buddylist. Even the synchronised chat across multiple clients would be possible. Filetransfers would become DCC….you get the idea.

This is our Whiteboard for this idea:

5. Implementation

Shortly after the brainstorming I started the Implementation of an IRC Server. Because we wanted a platform independent Implementation I decided to use .NET and C#. Since there is a .NET Framework for all Windows Operating Systems and Mono for all unixoid Operating Systems we got what we want. Even more: With Visual Studio we have a great development environment. (Well actually Namenlos won’t use Visual Studio…but at the moment the major part of the code is made in Visual Studio 2003)

When I started to write the first lines of code I thought about possible names. We started on the whiteboard with “Projekt Buffen” (don’t ask!) … I thought that “Jabbernaught” would be a great name… and after some Skype-Sessions we both thought that “multeem” would be a great name for the baby.

After some days of implementing I am proud to present the first sourcecode package: (61,54 KB)

This version of multeem implements an IRC Server without any Server 2 Server Communication and a load of bugs especially in the Channel Management. See it as a first prototype for the IRC Implementation and as a base for the future development.

7. The License

We release this and the following sourcecode packages under a BSD-like license (see license.txt).

8. What now?

Please comment and criticise our plans and ideas. Feel free to ask anything you would like to know. If you are interested in helping us in any way feel free to contact us.

Formula Student

Uhh it seems that there’s some racing stuff going on at my university:

“Formula Student is the biggest and best of its kind in Europe. Run by the Institution of Mechanical Engineers (IMechE), in partnership with the Society of Automotive Engineers (SAE) and the Institution of Electrical Engineers (IEE), it promotes careers and excellence in engineering, by challenging university students to design, build, develop, market and compete as a team with a small single seater racing car.”

Today evening (1900) there will be a meeting in ZHS201. I hope I can make some good pictures.

Apple screwed it!

Okay. Here’s the list what’s really driving me mad with Tiger:

  1. Pivot is not working correct. It flips the screen but it’s unusable because it’s far away from smooth… stuttering crap!

  2. the program icon in the dock is not filtered, pixel salad?!

  3. you cannot configure spotlight noteworthy… it just indexes your local hard drive. That’s it. You even cannot configure when and what. You just can define exclusions.

  4. Dashboard Widgets are crap. What the hell do I need a dictionary for when I cannot even select the language? Anyway: Konfabulator did it far better.

  5. many programs crash or run out of memory. For example: iPulse. I used it about 12 hours… first the iPulse graphics screwed up. Then the system ran out of memory resulting in an excessive swap orgy

  6. Quicktime 7 is far from smooth playback. Stuttering on a Mac where Quicktime 6 worked absolutly smooth. Even the new Fullscreen Zoom-Animation isn’t playing smooth. When you minimize the Quicktime Player to the dock the movie isn’t playing in the dock. Even worse when you do this the player crashes.

  7. the newly added RSS Screensaver just “exploded”… after one hour of use it came up with a… well bright cyan color which just hurts the eye. Of course: You cannot configure anything…

  8. Safari has some serious bugs. Sometimes it “forgets” to draw the scrollbar… The RSS Implementation is well…why no stand-alone App. Why integrated in Safari?

  9. Rendezvous=Bonjour. Well I wrote about that issue some months ago. And now it’s time to forget about Rendezvous. It’s now called Bonjour. (it’s not really something Apple screwed up ;))

  10. Apple changed for some strange reason the security settings so that Virtual PC isn’t able to install the “Virtual Network Switch”

I will complete the list when Panther is back running on my Mac.

    swim swim swim

    a few days ago this message came in… and mape reminded me today:

    Operas CEO John S. von Tetzchner claimed he would swim from Norway to the US if Opera is downloaded more than 1 million times. And the downloads are already far above 1 million. So … go go go ! 😉

    The training just has begun. You can read about it here.

    “Before the weekend, Opera’s CEO, Jon S. von Tetzchner boldy proclaimed at a company meeting that if download numbers of Opera 8 reached 1 million within four days he would swim from Norway to the USA. Opera’s communications department could not resist the temptation, and made his statement public. As any respectable CEO and gentlemen, Mr. Tetzchner stands by his word.”

    May the force be with him…

    Good Morning Linux!

    It’s so “funny” to read something like this:

    “Seiner(Andrew Morton) Meinung nach komme bei der Kernel-Entwicklung dem Testen nicht genug Aufmerksamkeit zu. Da die Tester weder Dank noch Geld für ihre zeitraubende Arbeit erhielten, würden neue Funktionen nicht genug geprüft. So könnten sich immer mehr Fehler in den Kernel einschleichen.”

    Oh. Finally the Linux Kernel Developers noticed that they do their work for free. And finally they must have noticed that some big companies are selling their work for real money.

    I don’t want to bash linux or the idea behind. I just want to say that you have to give up some principles to grow. What priniciples. I don’t know for sure.

    Seamless Windows with Microsoft Terminal Services…and without ICA

    I’ve searched quite a time for this solution. So take it with the same pleasure as I did. (it’s an order!). The best about this solution is that you don’t only get the compiled binary. You get some sort of short tutorial and the source. It’s far more than a crash course to Terminal Services. It extends the field of applications of the Terminal Services and on top you get knowledge for free.

    Microsoft’s terminal services client (also called ‘Remote Desktop Connection’) has one main thing against it. Remote applications do not appear as if they are running on the local desktop, instead they appear in a separate window which represents the server’s desktop. This is fine if you just want to work exclusively on the server, but can be a pain if you want to switch between applications on the server and the local desktop or want to run applications on different servers. What is needed is a way to display the remoted applications as ‘Seamless Windows’ on the client.

    Commercial products have been written to achieve this in a Windows environment, the most well known would be Citrix. Citrix uses its own protocol (ICA) to publish applications to the client. Others have used Microsoft’s protocol called RDP (Remote Desktop Protocol) with additional software to achieve the same effect (the most notable of these is Tarentalla’s Canaveral IQ – I suspect they use a similar, but more sophisticated, method to the one presented in this article).

    While these products provide a lot more than just seamless windows, they are also quite expensive. It would be nice to have this feature in a regular RDP client without having to buy a whole application publishing product.

    This article provides a possible solution to this problem by extending Microsoft’s RDP client using virtual channels to communicate between the server and the client. This option has been chosen over writing or extending an existing open source RDP client (such as rdesktop) because we will still be able to take advantage of all the features in Microsoft’s client (and presumably all new features they add in the future). Also, an advantage to using Microsoft’s client is that we can get some rudimentary application publishing over a web page since their terminal services client has an ActiveX component to do this.”

    Xyle scope CSS Analyse- and Authoring

    There are not many great CSS Editors. But there seems to be a new one that is really cool. Xyle scope. Because I will need a good CSS Authoring Tool in the near future this is quite helpful.

    “Einer der Gründe, warum ich Websites teilweise auf Firefox entwickele, ist der Live-CSS-Editor der Web Developer Toolbar. Ein geniales Ding, wenn auch ziemlich hässlich und manchmal ein bisschen buggy. Xyle Scope ist gewissermaßen die extrem aufgebohrte, native OS X-Variante dieser Grundidee.

    Xyle ist jedoch keine Safari-Erweiterung, sondern eine Standalone-Applikation, die auf dem Apple WebKit basiert und Seiten somit genauso rendert wie Safari. Hinzu kommt jedoch eine Seitenleiste, in der man sich allerlei CSS- und HTML-Strukturen anzeigen lassen kann. Dabei ist es egal, wo sich die Seite befindet, ob auf dem eigenen Rechner oder irgendwo im Web.”

    the perfect working environment

    Okay. It’s done. I’ve managed to create the perfect working environment for me.

    sorry for the distortions but the room is to small
    to avoid them with my camera…

    From left to right:

    • Mac mini 1.42 Ghz+Bluetooth 1GB RAM + Samsung 910T + Apple Wireless Keyboard

    • custom built PC P4 2.8 Ghz 1GB RAM + Belinea 102580 + Highscreen 19″

    • HP compaq nc8000 centrino notebook (1.5 ghz) 1GB RAM

    All three machines are hooked up to the FeM-Net which connects over 1500 machines across the campus with 100 Mbit and is connected to the university uplink with 1 Gbit.

    One floor below in the server-room is the fileserver located where I store most of my data(about 800 GByte at the moment). This machine is connected with 1Gbit to the P4 and 100 Mbit to the other machines.

    The best of this: it’s absolutely silent.

    Darwinia…retro graphics that remind me of TRON

    My colleague bereal told me about a new game for Mac and Windows. Not only that this game has a really innovative interface (you draw the commands with the mouse and manage them as “tasks” in a big computer-like task manager) it also has really great graphics. Not that they are very detailed or something. It’s just that their retro-look that makes it cool.

    “The world of Darwinia is a virtual themepark, running inside a computer network built by a computer genius named Dr Sepulveda. Darwinia is populated by a sentient evolving life form called the Darwinians. They are the product of a decades worth of research into genetic algorithms.
    Unfortunately, the systems of Darwinia have been overrun by an evil red Viral Infection. This Virus has multiplied out of control and must be stopped. Your task is to destroy the Viral Infection and save the Darwinians from extinction.”

    Celestia – the universe at your fingertips

    hmm…today must be the “show me teh starZ”-day…

    “… The free space simulation that lets you explore our universe in three dimensions. Celestia runs on Windows, Linux, and Mac OS X.

    Unlike most planetarium software, Celestia doesn’t confine you to the surface of the Earth. You can travel throughout the solar system, to any of over 100,000 stars, or even beyond the galaxy.

    All movement in Celestia is seamless; the exponential zoom feature lets you explore space across a huge range of scales, from galaxy clusters down to spacecraft only a few meters across. A ‘point-and-goto’ interface makes it simple to navigate through the universe to the object you want to visit.

    Celestia is expandable. Celestia comes with a large catalog of stars, planets, moons, asteroids, comets, and spacecraft. If that’s not enough, you can download dozens of easy to install add-ons with more objects. “

    I love colorful pictures… especially when they are generated by computers…

    “Gravit is a gravity simulator which runs under Linux, Windows and Mac OS X. It’s released under the GNU General Public License which makes it free. It uses simple newtonian physics using the Barnes-Hut N-body algorithm. Although the main goal of Gravit is to be as accurate as possible, it also creates beautiful looking gravity patterns. It records the history of each particle so it can animate and display a path of its travels. At any stage you can rotate your view in 3D and zoom in and out. Gravit uses OpenGL with SDL, SDL_ttf and SDL_image.”
