Open Source BigTable, Robots Lost, Changing the World, Secrecy Binge

  1. Accumulo — NSA’s BigTable implementation, released as an Apache project.
  2. How the Robots Lost (Business Week) — the decline of high-frequency trading profits (basically, markets worked and imbalances in speed and knowledge have been corrected). Notable for the regulators getting access to the technology that the traders had: Last fall the SEC said it would pay Tradeworx, a high-frequency trading firm, $2.5 million to use its data collection system as the basic platform for a new surveillance operation. Code-named Midas (Market Information Data Analytics System), it scours the market for data from all 13 public exchanges. Midas went live in February. The SEC can now detect anomalous situations in the market, such as a trader spamming an exchange with thousands of fake orders, before they show up on blogs like Nanex and ZeroHedge. If Midas sees something odd, Berman’s team can look at trading data on a deeper level, millisecond by millisecond.
  3. PRISM: Surprised? (Danny O’Brien) — I really don’t agree with the people who think “We don’t have the collective will”, as though there’s some magical way things got done in the past when everyone was in accord and surprised all the time. It’s always hard work to change the world. Endless, dull hard work. Ten years later, when you’ve freed the slaves or beat the Nazis everyone is like “WHY CAN’T IT BE AS EASY TO CHANGE THIS AS THAT WAS, BACK IN THE GOOD OLD DAYS. I GUESS WE’RE ALL JUST SHEEPLE THESE DAYS.”
  4. What We Don’t Know About Spying on Citizens is Scarier Than What We Do Know (Bruce Schneier) — The U.S. government is on a secrecy binge. It overclassifies more information than ever. And we learn, again and again, that our government regularly classifies things not because they need to be secret, but because their release would be embarrassing. Open source BigTable implementation: free. Data gathering operation around it: $20M/year. Irony in having the extent of authoritarian Big Brother government secrecy questioned just as a whistleblower’s military trial is held “off the record”: priceless.
