  • Profiles in IT: William Sterling Boyle and George Elwood Smith
    • William Sterling Boyle and George Elwood Smith are co-inventors of the charge-coupled device and shared half of the 2009 Nobel Prize in Physics for “the invention of an imaging semiconductor circuit—the CCD sensor.”
    • William Sterling Boyle was born August 19, 1924 in Amherst, Nova Scotia.
      • He was home schooled by his mother until age fourteen, when he attended Montreal’s Lower Canada College to complete his secondary education.
      • He joined the Royal Canadian Navy in 1943 during World War II.
      • He earned his BS in 1947, MS in1948, PhD in 1950 from McGill University.
      • After receiving his doctorate Boyle spent one year at Canada’s Radiation Lab and two years teaching physics at the Royal Military College of Canada.
      • In 1953 Boyle joined Bell Labs where he invented the first continuously operating ruby laser with Don Nelson in 1962 and he was named on the first patent for a semiconductor injection laser.
      • He was made director of Space Science and Exploratory Studies at Bellcomm in 1962 providing support for the Apollo space program.
      • He returned to Bell Labs in 1964, working on integrated circuits.
      • Boyle was Executive Director of Research for Bell Labs from 1975 to 1979.
      • After retirement in 1979, he settled in Wallace, Nova Scotia, and helped launch an art gallery with his wife Betty, a landscape artist.
    • George Elwood Smith was born May 10, 1930 in White Plains, New York.
      • Smith served in the US Navy
      • He earned his BS at the University of Pennsylvania in 1955 and his PhD from the University of Chicago in 1959 with a dissertation of only three pages, which he later described as "short, but pretty good."
      • He worked at Bell Labs in Murray Hill, NJ from 1959 to his retirement in 1986, where he led research into novel lasers and semiconductor devices.
      • During his tenure, Smith was awarded dozens of patents and eventually headed the VLSI device department.
    • Smith and Boyle sketched out the design for CCD device in an hour, over lunch at Bell Labs in October 1969. They had the device fabricated within two months.
      • The two were working on semiconductor integrated circuits, and Smith had been involved with trying to create an imaging chip for the Picturephone.
      • The idea is fairly simple. You start with a layer of silicon with an oxide (insulator) at the surface.
      • Atop the oxide, add an array of metal electrodes as gates, creating capacitors that can store charge.
      • When a photon strikes the silicon, it creates an electron-hole pair, and the electron moves toward an electrode into the well.
      • Electrons accumulate in the interface between the silicon and the oxide.
      • When you apply a sequence of high and low voltages to adjacent gates, the electrons move from one gate to the next, forming a electron bucket brigade.
      • At the edge of the chip, the charge can be converted to voltage and digitized.
    • Both Boyle and Smith were avid sailors who took many trips together. After retirement Smith sailed around the world with his wife, Janet, for five years.

  • MS has Recovered Sidekick Data
    • Sidekick customers in the U.S. will have "most, if not all" of their personal data recovered
    • Owners of the Sidekick cellphone lost their personal data, including contact and calendar information, when the servers storing the data crashed.
    • "We have determined that the outage was caused by a system failure that created data loss in the core database and the backup," said Roz Ho of Microsoft.
    • The smartphones, made by Microsoft subsidiary Danger Inc., were sold by T-Mobile in the U.S.
    • Although it’s not clear how many customers were affected by the server outage, T-Mobile’s financial statements suggest there are about a million Sidekicks in operation.
    • "We now believe that data loss affected a minority of Sidekick users," said Ho.
    • The Sidekick, launched in 2002, was an early entry in the smartphone market, featuring a large QWERTY keyboard for text messaging and instant messaging.
    • Its remote storage feature was considered innovative at the time — if the phone were lost, the customer’s data could be downloaded to a new handset. However, the Sidekick didn’t allow users to easily make backups of its data on a computer.
    • T-Mobile offered customers affected by the server crash a $100 credit for products and services, as well as a $20 refund for one month of data usage.
    • Some users have filed lawsuits against T-Mobile and Microsoft alleging negligence and false claims regarding the safety of their data.
  • Google Postini Customers Angry Over Outage
    • Google’s Postini message security and archiving service experienced significant e-mail delivery problems on Wednesday leading to complaints from business customers using Postini.
    • The day-long outage prompted pages of complaints on the Postini Help Forum, mainly focused on the lack of communication about the problem.
    • As a user identified as "Ajax517" put it, "This is shaping up to be a big FAIL on Postini’s customer service side."
    • A user identified as "jcinfargo" offered a similar assessment: "I talked to one reseller yesterday that also uses Postini and he said he has a law firm client that needed an e-mail for their client’s trial yesterday that they did not get. This is an epic fail on Google/Postini."
    • The service disruption also turned into an opportunity for competitors, with some users suggesting alternative business e-mail services.
    • A representative from one of those services even joined in the discussion, to present an engineering viewpoint and not to make a sales pitch, he insisted.
    • On Tuesday evening, a Google spokesperson said, "We’re aware of an issue that’s causing a delay in mail delivery for some Postini customers, and are working to fix it as quickly as possible. Outbound mail is fully functional, but inbound mail has been flowing at a reduced rate for affected users."
    • On Wednesday morning, at 1:49 AM Pacific Time, a Google engineer the situation had been resolved and that mail delivery rates had returned to normal. The posting states that while e-mail was delayed, "no messages were bounced or deleted."
    • As per the pattern in outages of this sort, there was an apology and a promise to post within 48 hours an incident report and a list of corrective actions to prevent a repeat of the problem.
  • BlackBerry’s New Storm Reviewed
    • BlackBerry’s first Storm met with mixed reviews.
    • I offered a screen that was not very responsive and sluggish operating speeds.
    • BlackBerry seems to have addressed many of these problems with the Storm 2, which goes on sale in the UK on October 26.
    • The new machine is slimmer and trimmer than the old design.
    • The touch-screen QWERTY keyboard is much improved, too, allowing for simultaneous double-touching for speed typing.
    • And it has Wi-Fi, a much needed addition.
    • Add to this the push e-mail and unrivalled security features that makes BlackBerry the default choice for industry worldwide.
    • This BlackBerry phone now includes as standard applications (Twitter, Facebook and apps to play video and music content)
    • The iPhone apart, this week alone, Sony-Ericsson has unveiled the Satio, its all-touch multimedia mobile smartphone, which features a 12.1 megapixel camera and a high-resolution screen, while HTC gave us the super-cute Tattoo, the latest smartphone to use the freely available Android touch-screen interface developed by Google.
    • The core market for the Storm 2 remains the business user, backed by an IT department running Microsoft Exchange.
  • Android May Overtake iPhone by 2012
    • Google’s Android will have more than quadrupled its market share by the end of 2012, according to Gartner has claimed.
    • Android’s market share stood at 1.6 per cent during Q1 2009, but will grow to 14.5 per cent by Q4 2012 rolls around, Gartner forecast.
    • This is based on an 522m smartphones shipping worldwide during the period.
    • Android will move from its current position as the sixth most popular operating system for smartphones to become the second most popular, Gartner said.
    • The main reason for Android’s market share growth will be because Google licenses their OS to multiple OEMs
    • Research in Motion’s BlackBerry OS is currently the second most popular handset OS will slip to fifth place by Q4 2012.

  • Security and Privacy Risks of Household Robots
    • Researchers from Univ. of Washington reported hacking results for household robots.
    • Results were reported at the 11th International Conference on Ubiquitous Computing, September 30th — October 3rd 2009
    • They studied examples of today’s robots in order to understand challenges for future household robots.
    • Robots could include webcam, microphones, and wireless Internet access.
    • They studied RoboSapien V2, the Rovio, and the Spykee.
    • The robots that we studied were purchased during or before October 2008.
    • They found several vulnerabilities in the robots that we studied:
      • Usernames and passwords used to access and control the robots are not encrypted, except in the case of the Spykee, which only encrypts them when sent over the Internet.
      • A malicious person could potentially intercept these to gain control of and access to the robots.
      • The audio-visual streams are not encrypted, except in the case of the Spykee, which only encrypts them when sent over the Internet.
      • When the Spykee uses encryption, it does so in a manner that may allow an attacker to decrypt the information (by performing a man-in-the-middle attack).
      • The Rovio’s audio-visual stream is never password-protected, even if the robot is configured to require a password.
      • When the network supports it, the Spykee can be accessed remotely, even if the "remote access" mode is disabled.
      • The Rovio has no way of disabling remote access.
      • The Spykee’s connection notification sound can be disabled by an attacker immediately muting the robot upon connecting.
      • The Spykee remains connected to the Internet whenever it is on its base, even if switched off.
    • These vulnerabilities mean that someone might be able to drive your robot around your home, look around the house, listen in on conversations.
