Mobile Phone Industry Steps Closer to VoIP

Wojtek Felendzer held a mobile phone to his ear as he walked across the room, the call automatically switching behind the scenes from a Wi-Fi wireless hotspot to the regular cellular network

Check out this article, found via slashdot bring on the Mobile VoIP goodness !

What’s really cool about this article as it describes a working implementation…

works by tunneling cellular information packets through the Internet when Wi-Fi is available and reverting to cellular towers when it is not.

This is the first implementation I’ve seen aimed at consumers, not businesses, no “call manager” needed, just cheap calls !

Virus or Worm ?

This is a quick note to myself really, as a security professional I get asked these questions a lot, and sadly each time I forget a nice simple answer, well this is what I think:

What’s the difference between a Virus and a Worm ?
A Virus is an application of malicious code.
A Worm is malicious code that can reproduce it’s self.

Following Feedback: Better Suggestions

  • A Virus infects another application for propagation.
  • Worms are self propagating code.

What’s the difference between spy-ware and malware ?
Spy-ware is hidden software specifically designed to monitor something without the user knowing ?
Malware is software posing as one thing, but with a hidden activity; so malware could cover both spy-ware and Trojans.

PacketFountain Settings !

pretty packets passing before your very eyes!

pretty packets passing before your very eyes!

I found this screen saver on digg, the idea is that it captures packets off the network card and bounces them around the screen.

If you read the comments on digg, some users complain that the implementation isn’t as slick as it could be; well I agree to an extent, but since I know bugger all about VB programming, and I’m not about to fork out for visual studio, I can’t complain to much. In light of this I decided to play with the settings to see what results I could get; the screen shot (pic from cam’ phone) is what I’ve managed, it doesn’t look half bad; and since I like to have most things encrypted most of what you see is rubbish, what’s cool is seeing what’s not !

My Settings are:

  • Speed 145
  • Packets 28
  • Base Font Size 20

Now I suppose results depend on your machine, but it’s worth a go eh !
