P2P

Hey Everyone,
Today's topic is P2P file sharing, which I think that a lot of people are now familiar with.

I often utilize a file sharing service for group assignment or presentation at college.
For example, Google Drive was very useful to prepare presentation efficiently with my group last semester. One of the group members uploads a file and share it with rest of members on Google Drive. Since each member has a busy schedule, it is difficult to meet up and prepare for the presentation together. Then, the file sharing system makes it possible for us to share information and to create ppt whenever we have time.

Next, what is "P2P" file sharing? (Just in case, P2P stands for "Peer-to-Peer!") One of the most successful programs would be BitTorrent, which Bram Cohen created. A person uploads any file like TV shows or movies as a "torrent," and anyone can download the file from the person's place (torrent). When you miss an episode, you go to Torrent and will find what you want!
BitTorrent makes it much faster for users to upload and download enormous amounts of data. According to an article called "The BitTorrent Effect," more than 20 million people have downloaded the application.

I have heard of Winny, which is a Japanese P2P file sharing program. However, a developer of Winny, Isamu Kaneko, was arrested for suspected conspiracy to commit copyright violation in 2004. These kinds of service is very sensitive to law and developers cannot avoid issues such as pirate and copyright violation from other industries.

I also think that subscription video on demand service such as Netflix and Hulu is a great strategy to let users leave illegal-ish activities. They provides various videos like TV shows, cartoons, and films with reasonable monthly pay. Consumers just need reasonable and satisfactory service, so why not leave for these service?
I used Torrent a couple times, but now I am a fan of Netflix ;)

See you in a next blog!
