BitTorrent Privacy Threats

While many organizations use the BitTorrent protocol as an efficient way of distributing large volumes of data (i.e. Linux DVD ISO files), others use it to distribute copyrighted or protected content.  With the large volume of users and traffic (from 27% to 55% of total internet traffic depending on geographic location), some users feel a sort of anonymity in all those numbers.  Researchers at the French National Institute for Research in Computer Science and Control (INRIA) collected 100 days worth of BitTorrent traffic from one client machine and analyzed it.  Even using anonymizing networks such as Tor, they were able to retrieve as many as 70% of the original host computer IP addresses.  Mind you this is not data collection at the center of the network, but data collection and processing from a leaf node to the network.  It is definitely worth a read if you are interested in internet privacy issues.

So many changes

In the past few weeks Miles' growth and development has been amazing.  Our little man races all over the house chasing the dogs and cats.  As of last week he is 27 pounds and is 32" tall.  This makes him a good three inches taller than He Pingping, the worlds smallest man. He seems to be happy trying all different types of food, but definitely hates peas and mango so far.  His favorite thing so far is his mother's special chicken and apple baby food that she prepares from scratch (as scratch as you can be without raising the chickens, I guess). Miles' started walking for real on 4/27 and started saying his first real words on 4/25.  He was very talkative several months before, but now he clearly states that he knows Wubbzy from the television show Wow! Wow! Wubbzy, by telling us "Wow Wow".

Bloop?

I am always a fan of NASA's Astronomy Picture of the Day (APOD) website, as they always find a way to see the beauty in science. The picture below is the visualization of a sound collected from undersea microphones in 1997.  The sound, otherwise known as "The Bloop", could have been generated by a living creature that is several times the size of blue whale, or just the result of an iceberg breaking loose.  There is so much about the world around us (and below us) that is still unknown!

Earthquakes

Where are your tax dollars going?  Well, some of them are going right here... to the USGS to allow them to notify you of earthquakes.  In the last few days there have been several large quakes in Mexico, so this service has taken a pretty heavy load from the web.  The neat feature of this web site is that you can program it to send you an SMS text after an earthquake, so you don't even have to go online to find out how big and where.
