Hi Folks,
Rather than use MAL, why not use SyncML? The source is readily available, and also includes demo code for a server and a client. The server uses Lotus Notes, and the client runs on a Palm.
Check out www.syncml.org.
Since this is similar to a denial-of-service attack (continually requesting a service), the battery drain technique should work ok. Since you can keep the device broadcasting on a faster than normal basis, the battery will be drained faster.
However, most of these devices are rated on just this sort of continual broadcast. Take a look at the specs for recent cell phones. They list total broadcast time, as well as standby time. Bluetooth specs also detail power drain on a broadcast/standby basis.
End result? Manufacturers will get wise to these attacks, and figure out a way to ignore malicious devices. I seem to remember them talking about this, but I don't remember any documents regarding this.
However, this is just one of the issues being addressed in the Bluetooth (pico area nets) and 3GPP (next generation mobile phones) groups. The really big problem is how do you keep others from listening in on your conversation. In both groups, part of the answer is frequency hopping, plus a small amount of encryption (allowed by the Feds). Authentication is already in place to disallow most spoofing. It is always possible to spoof, just depends on how hard you have to work at it.

If you read the article carefully, you might have noted that the device is for the 3G network - not CDMA. They are using the WCDMA until the 3G network is up and running. The 3G network is supposed to have some amazing bandwidth. The article mentions some of the slower rates.
The mess you are referring to (CDMA vs GSM vs PCS) is being resolved in the 3GPP committee. 3GPP is the next generation cell phone consortium. All the major players of devices are supporting this, as are most of the service providers. If you are really having trouble sleeping, check out http://www.3gpp.org/ ^_^
Lots of fun stuff coming up in that network. You'll have a lot more capability than the limited stuff in GSM or CDMA. I'm still learning all the bells and whistles they are putting in...just need more coffee to get through some of the documentation.
First off, I agree with the other replies that Wabi was just obsolete compared to Wine. However, it is not wise to think that Sun is going to be kind to StarOffice. They've already killed other fine products for OSs other than Sun. Perhaps it is unkind, but they bought a company making products for NeXTStep/OpenStep, and then pulled all the personnel off to other projects. Effectively killed the products.
I'm sure the decision to move the people elsewhere made sense from a business viewpoint, but it didn't help the OpenStep community one bit.
Motorola is one of the bigger CPU manufacturers, and Metrowerks makes a compiler for most of them. Why would they cut their own throat? I suspect the real reason they bought the company is to ensure those compilers continue to exist and be supported.
As for the speculation that Motorola is going to get the compiler at cost...well, not bloody likely. Metrowerks is going to be an independant company under the Motorola umbrella. They will still have to make a profit. They *might* give a slight price break to people inside Motorola, but more likely they will charge full price.
I suggest you try to think from the perspective of the Board, rather than the end-user. It is sometimes quite enlightening. Yes, sometimes depressing, but not all that often.
I've seen Sun buy up successful companies before, with the intent of supporting them. Then, after a while, slowly, and if possible, quietly, using the personnel for other uses. They did this with a big OpenStep developer (I can't remember their name right now). They did this with Island.
Let's hope that they don't screw this one up, too. However, I suggest you don't hold your breath. Blue looks odd on humans.
Quite true except that Sun hasn't shipped their compiler with their OS for quite some time. The poor user would have to go and get a binary of the compiler, then set up the compiler to work on their system, and *THEN* compile the code. A lot more painful that just downloading the binary.
It would not suprise me if the theatre was blocking the phone signals during the movie. There are a couple of manufacturers that sell devices that block the phone/pager frequencies. The Japanese use them a lot at restaurants and cafes. Very effective enforcement of ettiquette. ^_^
That is a very important point. It is one that he raised quite a bit in other interviews - that we need to have an eye on the people in power. That means we have cameras (and microphones) in *ALL* public places, and *ALL* government buildings. Those people work for us, we should be able to see what they are doing with our money.

Let's see how Sun treats the Linux community.
Uh, that's Weird Al, right? Some attribution would be a nice thing....
What do you base this silly statement on?

I forget where I first saw this (it might have been /. I dunno). On Freak Tech, I found the URL for FSCRs (Fractal Shape Changing Robots).
http://www.stellar.demon.co.uk/#introduction
Not quite the same thing, but similar. The FSCRs allow for multiple robots ganging together for more difficult tasks.
I wonder how long those Micro-robot critters can run without power?
