  • Last year, Amazon.com founder Jeff Bezos announced that he had located some of the Apollo F-1 rocket engines and planned to recover them
  • his Bezos Expedition team were successful in recovering engines that helped power Apollo astronauts to the Moon and have now brought “a couple of your F-1s home,”
  • There is no indication so far from Bezos of which flight these engines were from
  • ...9 more annotations...
  • Last year
  • he said they had found the engines from Apollo 11, but it may be been difficult to determine exactly which flight the ones found were from
  • NASA launched 65 F-1 engines, five per flight, on 13 Saturn V boosters between 1967 and 1973
  • Supposedly there would be serial numbers to make the identification of which flight these engines were from
  • still on the ship, so perhaps the identification will come later
  • Each of the engines stands 19 feet tall by 12 feet wide and weigh over 18,000 pounds.
  • Five F-1 engines were used in the 138-foot-tall S-IC, or first stage, of each Saturn V
  • three weeks at sea, working almost 3 miles below the surface
  • photographed many beautiful objects in situ and have now recovered many prime pieces

  • Amazon.com founder Jeff Bezos has located the Apollo 11 F-1 rocket engines and plans to recover them
  • using state-of-the-art deep sea sonar, the team has found the Apollo 11 engines lying 14,000 feet below the surface
  • making plans to attempt to raise one or more of them from the ocean floor
  • ...9 more annotations...
  • don’t know yet what condition these engines might be in
  • they hit the ocean at high velocity and have been in salt water for more than 40 years
  • The Saturn V used five F-1 engines in the first stage
  • F-1 is still the most powerful single-chamber liquid-fueled rocket engine ever developed
  • producing one and a half million pounds of thrust, burning 6,000 pounds of rocket grade kerosene and liquid oxygen every second
  • On July 16, 1969, Apollo 11 was launched and the five F-1s burned for just a few minutes, and then plunged back to Earth into the Atlantic Ocean.
  • the engines remain the property of NASA
  • hopes that the space agency would allow the recovered engines to be displayed at the Smithsonian or another museum
  • no public funding will be used to attempt to raise and recover the engines, as it’s being undertaken by him privately

  • Glooko helps diabetics check their blood sugar daily. Glooko is a Palo Alto startup that presents its core product as two items: a free-to-download logbook available at iTunes and a fee-charged cable, sold separately, at $39.95 from Amazon
  • MeterSync cable device. You plug it into the meter and the phone, and that is all.
  • the record-keeping features are able to carry information beyond meter readings. The user can generate a more informative record of the condition, by noting down varied factors that affect blood glucose.
  • ...3 more annotations...
  • Information from the logbook can then be emailed or faxed as a 14-day summary to the doctor
  • The patient can mark off notes about whether the reading was done before or after a meal, the number of carbs consumed, or can click on a predefined list of lifestyle factors
  • nearly 26 million adults and children in the United States -- or 8.3 percent of the population -- have diabetes.

  • Without some of the sci-fi gimmickry, police departments from Santa Cruz, California, to Memphis, Tennessee, and law enforcement agencies from Poland to Britain have adopted these new techniques
  • criminals follow patterns, and with software -- the same kind that retailers like Wal-Mart and Amazon use to determine consumer purchasing trends -- police can determine where the next crime will occur and sometimes prevent it.
  • criminal behavior was not that different from examining other types of behavior like shopping

  • People are creatures of habit
  • could help in cities where tight budgets were forcing patrol reductions.
  • The key to success in predictive policing is getting as much data as possible to determine patterns. This can be especially useful in property crimes like auto theft and burglary, where patterns can be detected
  • factors in attributes like the time of year, whether it is hot and humid or cold and snowy, if it is a payday when people are carrying a lot of cash
  • not saying a crime will occur at a particular time and place
  • can expect a wave of vehicle thefts based one everything we know
  • officials said serious crimes fell 30 percent and violent crimes declined 15 percent since implementing predictive analytics
  • in 2006
  • CRUSH -- Criminal Reduction Utilizing Statistical History
  • targeted certain "hot spots" to allow police to deploy more efficiently
  • "If the data is indicating a hot spot, we are able to immediately deploy resources there
  • beat officers can use their instincts for similar results
  • software could be far more precise, such as predicting burglaries in a small geographic area between 10 pm and 2 am.
  • the software was able to help police break up a group that was committing armed robberies
  • 84 robberies, but we had no idea it was so organized
  • crunching the numbers, police were able to pinpoint the zone and time of likely holdups
  • police officials from as far away as Hong Kong, Rio de Janeiro and Estonia have come to review the experience in Memphis
  • In Los Angeles, another program
  • was tested in a single precinct, and resulted in a 12 percent drop in crime while the rest of the city saw a 0.2 percent increase

  • technology could be positive but that it could lower the threshold for constitutional protections on "unreasonable" searches.
  • IBM's Cleverly said the technology can in many cases improve privacy
  • How do you cross-examine a computer
  • If the search is based on a computer algorithm
  • how will this affect reasonable suspicion

    nd in a lot of instances we are able to make quality arrests because we're in the right area at the right time," he told AFP. Although beat officers can use their instincts for similar results, Williams said the software could be far more precise, such as predicting burglaries in a small geographic area between 10 pm and 2 am. In one case, the software was able to help police break up a group that was committing armed robbe
