• Apple Newton

  As a proud owner of a Newton 2000+ (I sent it in to Apple for an upgrade when the 2100 got introduced), thought a comparsion of a Newton to a UMPC was interesting. Guess who won? http://digitalliving.cnet.co.uk/specials/0,39030785,49282099-1,00.htm [via TUAW ] Read More... Posted Friday, July 28, 2006 7:00 PM from meta-douglasp | 0 Comments

• PhotoSynth Technology Preview

  Microsoft has announced some cool new collaborative photography software in the form of PhotoSynth on the Live Labs web site. http://labs.live.com/photosynth 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. With Photosynth you can: walk or fly through a scene to see photos from any angle seamlessly zoom in or out of a photograph even if it is gigapixels in size see where pictures were taken in relation to one another find similar photos to the one you're currently viewing explore a custom tour or see where you've been send a collection to a friend http://labs.live.com/photosynth/blogs/Announcing%2BMicrosoft%2BLive%2BLabs%2BPhotosynth%2BTechnology%2BPreview.aspx The site includes videos describing the technology and the manner in which it was developed - a collaboration between MSR, Live Labs, the recently acquired Seadragon team, and the Windows PIX Team. PhotoSynth really embodies the kind of innovative, next-generation photo experience that many folks at Microsoft have been noodling on for some time.... Read More...

• Symmetric Cipher Suites

  The list of commonly used stream ciphers is very short because there's really only one. RC4, developed by Ron Rivest, is essentially the only stream cipher that has been widely deployed. RC4 is very fast and found in wireless networking devices, as part of Wired Equivalent Privacy (WEP) and WiFi Protected Access (WPA), among other places. WEP does not offer much protection because a wireless network with lots of WEP traffic will reuse portions of the key stream if you listen patiently for a while. This is exactly what you weren't supposed to do with stream ciphers. This is more a poor use of RC4 rather than a flaw in the algorithm itself. WPA is a replacement for WEP that provides better security. The RC4 key stream is generated from a 256 byte state array using a pseudorandom number generator. Each time random bits are generated, the state array gets slightly scrambled so that future output bears very little resemblance to past output. The state array is initialized by the encryption key. Encryption keys can be between 1 and 256 bytes long, with shorter keys essentially repeated to pad out the length. Initially, the state array has a fixed value. The algorithm is then initialized by looping over the repeated encryption key and scrambling the state array according to the key bit values. The encrypted stream is generated by taking the exclusive-or of the bits of the input stream with the randomly-generated bits. Next time: More Symmetric Cipher Suites Read More...

• Remoting posts

  As Doug indicated I was going to post my deranged .NET Remoting ramblings in my blog. But then John had created a cool blog especially for our Remoting users. So I'll start putting my Remoting posts there. Read More... Posted Friday, July 28, 2006 1:58 AM from Sowmy Srinivasan's Blog | 0 Comments
