The 1989 C standard didn’t allow variable argument macros. They were added in the 1999 standard. To use one according to the standard, plug in “__VA_ARGS__” where you want the variable arguments. For example:#define print(…) real_print( __VA_ARGS__ , 0)
Of course, your compiler may or may not support either this feature or a nonstandard variation.
You might have guessed that, after all those years, the MS compiler still does not support them!!! arghh. crap.
Some while ago, I was considering to buy a gyroscopic mouse from Gyration for my future Media Center, but I’m becoming more and more convinced I should simply buy a Wiimote instead 
There are lots more possibilities while still fulfilling the original needs. The Wiimote IS a gyroscopic mouse but adds the following advantages:
After looking at all the neat programs Johnny Lee put together, I guess you understand I can’t wait to try this out myself 
Also, be sure to check out his blog and numerous videos floating around the web.
First time I heard of the cool wiimote possibilities was when reading a post of Xfennec, in which he made a simple showcase of the possibilities with libwiimote using his favorite 3D engine Raydium. Be sure to check out the vid. I was really impressed back then, but of course Johnny did a lot more impressive stuff, the guy is a legend by now. Johnny does not use the libwiimote lib, but rather the dotnet WiimoteLib (I mention this ref especially for andrasj )
I have to admit that at first glance the .net lib seems more attractive due to its event based mechanism (internally, it does an async read on a stream in a loop though). The C lib looks a bit more basic but very easy to get started.
I was quite astonished to read about this BUG platform: “an open source, web-enabled, modular software + hardware platform”. This kinda says it all. It’s still in beta, but they are targeting Q4 2007 right now to release their BUG-base, the core product, featuring an ARM microprocessor and all kind of interfaces you might desire (notice the MPEG4 HW encoding/decoding support!). Like this featurefest is not enough yet, you can extend the base station with all kind of modules: “GPS, Digital Camera / Videocam, Touch-sensitive Color LCD Screen, Accelerometer, Motion Sensor”, you name it! Before you stop drooling over the hardware specs, save some drool to drool on the software specs. They have it nicely running on an OSGi framework! Extension galore. Judging by the screenshots, I have the impression they are running it on the eclipse framework which is an extension of OSGi (Paul, correct me if I’m wrong ;)).
This really seems the ultimate “toy for boys” or “Lego Mindstorms for adults” at least in a geeky world
Reminds me of this site/magazine where creating DIY gadgets is just daily routine..
In case you care when you will finally be able to mix heavy- and lightweight components in java 1.7: release plan
with this perl script.
It also made me discover the googlepages project which I didn’t know of yet. I guess it’s simply not possible anymore to keep up with all the projects Google comes up with.
