you want to get your hands on the Windows Kernel, don’t you?

the UK Academic Team Blog writes:

“The big kahuna – a source-code release of the Windows Kernel. The WRK is useful in design projects that let your students explore OS principles using the Windows kernel sources, the WRK enables advanced teaching and research by facilitating building experiments and projects based on modifying the Windows kernel, as well as by promoting better understanding of the Windows architecture and implementation.”

More info on that when I have more info on that…

a ready to go VMware Image for MONO…

The Mono team (well, Novell) created a mono-development-environment-in-a-box as an VMware Image. You can grab it at the source.

“The image is a SUSE Linux Enterprise Desktop 10, and it includes the latest version of Mono, the development tools, documentation and samples for Windows.Forms and ASP.NET.

The MonoDevelop IDE is included in the image for developers, and Postgress and MySQL are installed to test your application with a database.”

I’ve made some screenshots:

synthesize your photography…

Once again a technical preview for something really amazing (which was acquired by Microsoft earlier this year)

“Photosynth is an amazing new technology from Microsoft Live Labs that will change the way you think about digital photos forever.”

Mhh…yeah, of course… so what does it really do?

“Photosynth takes a large collection of photos of a place or object, analyzes them for similarities, and displays them in a reconstructed 3-Dimensional space.”


“Each photo is processed by computer vision algorithms to extract hundreds of distinctive features, like the corner of a window frame or a doorhandle. Then, photos that share features are linked together in a web. When a feature’s found in multiple images, its 3D position can be calculated. It’s similar to depth perception—what your brain does to perceive the 3D positions of things in your field of view based on their images in both of your eyes. Photosynth’s 3D model is just the cloud of points showing where those features are in space.”


“The Photosynth client shows you the 3D pointcloud, but more importantly, it also shows you the original pictures overlaid on the model. Imagine a slide projector placed at each camera position, aimed where the camera was aiming, and projecting the picture that camera took. A screen is placed in the 3D environment at an appropriate distance from the projector. As you move around in the Photosynth environment, projectors turn on and off, giving you a changing perspective on a world built entirely out of the original photos.”


“Imagine being able to see your favorite band from either the front row or the bleachers, walking around that new motorbike you’ve been thinking of buying, or flying over every nook and cranny of a famous landmark.

Photosynth provides easy controls for exploring a collection of photos in 3D with a click of a mouse. If you’ve ever played a 3D game you already know how to use Photosynth.

Seeing your photos displayed in 3D instead of a boring old slideshow changes the way you think of taking—and viewing—pictures. Add the ability to see your pictures together with those taken by other people and you’ll start to see the endless possibilities that Photosynth promises to provide.”

get me a Cerbera or a Sagaris…you decide

I do like two car manufacturers (well, their cars to be precise) more than all the others. One of them is Mercedes-Benz and the other is…TVR. Yes, the brits.

They make great looking powerful sports cars and I hope one day one will be mine 😉 They are quite affordable compared to other supercars – for example you can get a brand new TVR Sagaris (4l V6) for 80k EURO…a pre owned 2004 Cerbera (4.5l V8) comes for about 48k EURO…did I mention they do not come below 380 bhp and weigh as much as two packs of chewing gum? (I’ll have to pay royalties to Jeremy Clarkson for that…damn!).

The fact is that the Cerbera has gone out of official production in 2004. But now TVR is auctioning the last made Cerbera on the Internet:

Yes, you can get that brand new, pepper white, 420 bhp supercar…just sign up and bid…well if you have the money (which I don’t)…

Beside the Cerbera I fell in love with the Sagaris…look how gorgeous it is:


raaawwrrr!!

I just found the sagaris video:

If you want to buy me one…contact me 🙂

real time radiosity lighting … soon in a game near you?

It seems that a company called Geomerics has developed an algorithm that allows real time radiosity lighting in fairly complex environments. They support nearly all the things you would expect, like soft shadowing, infinite light bounces, colour bleeding:

If you don’t know what radiosity is:

“Radiosity is a global illumination algorithm used in 3D computer graphics rendering. Unlike direct illumination algorithms (such as ray tracing), which tend to simulate light reflecting only once off each surface, global illumination algorithms such as Radiosity simulate the many reflections of light around a scene, generally resulting in softer, more natural shadows”

Since you of course know how radiosity works you can imagine that it’s dead slow. And getting it up to real time is the important thing about the new algorithm.

They demonstrate their technology in a short movie:

“Geomerics real-time lighting technology incorporates all of these effects in an ‘infinite bounce’ setting. Lights can be moved dynamically, so characters exploring a scene with a torch, for example, can now experience the scene being lit as it would be in the real world. Furthermore, artists can create lights dynamically to ensure that scenes are lit the way they intended, in a similar manner to movie sets.

Our technique also supports real-time area light sources, smooth soft-edged indirect shadows, projected lighting, spot lights, colour bleeding and texture-based lighting effects such as normal and bump mapping.”

browse the web with the iLiad

The iRex iLiad e-ink e-book reader is such a fantastic device, a friend of mine is willing to put the >600 euro down to get one. And if he reads this, he’ll be even more motivated to bite the bullet:



“From the factory, the Iliad only uses and maintains Internet connectivity for a very short time and for one specific purpose; to connect to the Rex site. Some enterprising device owners put a little hack together with a PDF file and some http for an address bar and they’re now surfing the web as long they like on the Iliad.”

Microsoft released the Windows Mobile Device Emulator (ARM CPU) Sourcecode


Once again an very interesting piece of software made it to the Shared Source family.



“The Device Emulator is a software simulation of a CPU and motherboard, that runs the Windows CE and Windows Mobile operating systems. The emulator is a single Windows .EXE file that contains:



  • A CPU emulator that executes the ARM instruction set by JIT-compiling to x86
  • An MMU emulator to support virtual memory and page protection
  • A motherboard emulator that contains emulated RAM and NOR flash memory
  • A collection of peripheral devices attached to the motherboard: serial ports, LCD controller, touchscreen, keyboard, interrupt controller, programmable timers, real-time-clock, network cards, audio, etc.
  • A “DMA” interface which allows a Win32 application running outside the emulator to communicate with a WinCE application running inside the emulator, using a simple socket-like programming model. “

a captcha a day keeps the spam0r away.

“A CAPTCHA (an acronym for “completely automated public Turing test to tell computers and humans apart”, trademarked by Carnegie Mellon University) is a type of challenge-response test used in computing to determine whether or not the user is human.”

This technology is mainly used to filter all those spammers from the normal commenting users. Schrankmonster even uses this technology. Kiesow doesn’t like very long captchas and I don’t like dumb ones…like this one which was sent in by Tomasz Naumowicz:

how Google Map/Earth works…

I want to share with you a fantastic page where Pascal Buire discusses his investigations on Google Earths tiling and algorithms:

“This is my analyse about how google map works, et specially how the tiles are encoded. Google map uses pre-rendered tiles that can be obtained with a simple url. This article explains how to build the url for a tile from its geo coordinates (latitude/longitude)”

Google Earth mirroring anyone?

Super Mario War…again

More than 2 years from now I wrote about Super Mario War. And now it’s time to take another look on the project and the upcoming version.

Super Mario War is a Super Mario multiplayer game. The goal is to stomp as many other Marios as possible to win the game. It’s a tribute to Nintendo and the game Mario War by Samuele Poletto. The game uses artwork and sounds from Nintendo games. We hope that this noncommercial fangame qualifies as fair use work. We just wanted to create this game to show how much we adore Nintendo’s characters and games.

Features:

  • Up to four players deathmatch fun
  • a whole bunch of game modes (featuring GetTheChicken, Domination, CTF, …)
  • Comes with the leveleditor – you can create your own maps…
  • … and a lot of people did so. There are currently over 400 maps
  • More fun than poking a monkey with a stick
  • The whole source code of the game is available
  • uses SDL and is fully portable to windows, linux, mac, …
  • CPU Players
  • will make you happy and gives you a fuzzy feeling

revisited: what’s the size of the earth compared to…and why earth needs a haircut…

A couple of days ago I wrote about a website that has some interesting pictures of the planets of our solar system compared to each other in size. The idea was great but the quality of the pictures was bad. So we decided to push our knowledge about 3D tools a bit and render our own high-quality version.

But first a before-after comparision:


before

Aaaaaand:


after

Tell us what you think of it!

We will add some more pictures in the next hours, beside that a short movie in 720p is in the rendering process at the moment.

Last time I worked with 3D tools they were called “3D Studio Max 3.0″…which is quite a while ago. 3D Studios current version number is 8… You can grab your own trial version here.

We actually experimented a lot with the tools…look what earth became after just seconds of play:


yes,we even hair-styled earth!

udp multicast to tcp unicast proxy YAPS revisited…and bugfixed

Yesterday I had an idea how I could fix the last remaining problem in my udp multicast to tcp unicast proxy server (YAPS).

The last time I had to report this:

“There are some glitches I am afraid to say: one known bug is that there are 12 bytes to much in the outgoing data stream which corrupts the picture. If anyone here can fix it: Do it please 😉 I tried one day and I could not find a solution for the problem.”

My idea was now, that those glitches are possibly there because some bytes of the header remain in each packet and therefore the movie stream itself is destroyed. MPlayer was able to display something, but as I said…glitches.

So I made a method that actually calculates the size of the header of each RTP packet and then removes this header:

   1:  public byte[] killRTPheader(byte[] b,ref int inlength)
   2:  {
   3:  byte[] outbytes = new byte[1600];
   4:  int headersize = 12+4*((b[0] >> 0) & 0x0f);
   5:    Array.ConstrainedCopy(b, headersize, outbytes, 0, inlength - headersize);
   6:    inlength = inlength - headersize;
   7:  return outbytes;
   8:  }

The results speak for themselves: A perfect sound and picture.

Beside that I added some additional features. Read the source and you’ll find out.

You can grab the source and binaries here: YAPS.zip (24,74 KB)

because he could…3D renderer in PHP

People do almost anything just because they can, and this guy is no exception:

“This evening I remembered an idea I had a while ago to make a 3D renderer in PHP (and if anyone’s tempted to ask – “because I can” ). I did a bit of reading on old 3D engines, as I didn’t want something modern and slow, and found out that the “raycaster” rendering used in Wolfenstein 3D is ridiculously easy to implement. A few hours later and it’s up and running I’ve not run any proper speed tests yet, but the images load up pretty much instantaneously. I have a couple of ideas of what this could be used for, so watch this space “

cracking galileo positioning system and talking about it…

The americans managed to crack…well they call it different but the fact remains that they cracked the PRN codes of the european global non-military positioning system called “Galileo

“Because GPS satellites, which were put into orbit by the Department of Defense, are funded by U.S. taxpayers, the signal is free — consumers need only purchase a receiver. Galileo, on the other hand, must make money to reimburse its investors — presumably by charging a fee for PRN codes.”

Imagining the tenth dimension


“The “theory of reality” that I advance on this website and in the book “Imagining the Tenth Dimension” is not the one that is commonly accepted by today’s physicists. Anyone wanting to know more about the currently established thinking behind string theory and the tenth or eleventh dimension should refer to such excellent books as “Parallel Worlds” by Michio Kaku, “The Fabric of the Cosmos” by Brian Greene, or “Warped Passages” by Lisa Randall.

I invite you to think of this as an entertaining diversion that for some people will have a strong and thought-provoking connection to their impression of how the world really works. If you click on “The Forum”, you will be taken to a page that gives readers an opportunity to debate the concepts presented in the book and this website more fully. Enjoy!”
