    Covert surveillance capability The school loaded each student's computer with LANrev's remote activation and tracking software. This included the now-discontinued "TheftTrack".[17][25][26][27] While TheftTrack was not enabled by default on the software, the program allowed the school district to elect to activate it, and to enable whichever of TheftTrack's surveillance options the school desired.[8] The school elected to enable TheftTrack to allow school district employees to secretly and remotely activate a tiny camera webcam embedded in the student's laptop, above the laptop's screen.[17][25][26][27] That allowed school officials to secretly take photos through the webcam, of whatever was in front of it and in its line of sight, and send the photos to the school's server.[8][17] The system snapped and sent a new photo every 15 minutes when the laptop was on, and TheftTrack was activated, though school employees could adjust the timeframe to as low as one-minute intervals.[8][28][29] LANrev disabled the webcams for all other uses (e.g., students were unable to use Photo Booth or video chat), so most students mistakenly believed that their webcams did not work at all.[30] In addition, TheftTrack allowed school officials to take screenshots (pictures of whatever was on the laptop's screen), and send them to the school's server.[8][17] Furthermore, a locating device would record the laptop's Internet (IP) address, enabling district technicians to discover which city the laptop was located and its internet service provider. (A subpoena to the provider would be required to pinpoint the exact location.) [29] In addition, LANrev allowed school officials to take snapshots of instant messages, web browsing, music playlists, and written compositions.[17][31] After sending the image to the school's server, the laptop was programmed to erase the "sent" file created on the laptop. That way, there would not be any trace by which students might realize that they were being watche

data centers energy 2.3 Environment

  • McKinsey & Company analyzed energy use by data centers and found that, on average, they were using only 6 percent to 12 percent of the electricity powering their servers to perform computations. The rest was essentially used to keep servers idling and ready in case of a surge in activity that could slow or crash their operations.
  • To guard against a power failure, they further rely on banks of generators that emit diesel exhaust.
  • Even running electricity at full throttle has not been enough to satisfy the industry. In addition to generators, most large data centers contain banks of huge, spinning flywheels or thousands of lead-acid batteries — many of them similar to automobile batteries

      How does this work? What are the technical terms. (CT)

      The iPlayer service is able to detect you're IP address or ISP through your network and track down your location. As every area has a different IP, it would be easy to locate. There are IP locaters that allow systems to track physical locations around the world.  Unless you use a proxy server, it would be harder to track down your physical location, as it has no direct route back to your computer.
  • f you've got access to a PC back in the United Kingdom you can make a virtual private network tunnel back to that PC and connect to the iPlayer web site thru that PC, this can cause it to look like you are in the United Kingdom.

      A VPN is a private network that uses a public network to connect remote sites or users together. A key feature of a VPN is its ability to work over both private networks as well as public networks like the Internet.

      TOR and Foxyproxy are examples of alternatives for VPN. TOR(The Onion Router), is an online anonymity system keeping user's internet activities from being monitored. Foxyproxy is a a firefox plugin that allows you to add proxies, keeping your ip hidden when you use it.

      Who are the stakeholders and how are they affected by this technology? (WL)

      The stakeholders would be the users of BBC iPlayer. Though they are users of BBC iPlayer, but they only can watch the TV at restricted areas. If they want to have access to BBC abroad they would have to search through the internet for TOR or Foxyproxy to provide them with a VPN. This may cause BBC iPlayer to slow down as there are many free users who are using the website too, therefore users of BBC iPlayer may not be able to watch the TV consistently.
