“Prior to this appointment, Dugan held several key positions in industry, most recently as president and chief executive officer of RedXDefense, LLC, which she co-founded in 2005, a company that develops defense against explosive threats. She has also served in senior executive positions in several additional companies in roles ranging from global sales and marketing to research and product development.
During her first tour at DARPA from January 1996 to May 2000, Dugan received the program manager of the year award for her leadership of the “Dog’s Nose Program”, which was focused on the development of an advanced, field-portable system for detecting the explosive content of land mines.
…
She has participated in wide-ranging studies for the Defense Science Board, the Army Science Board, the National Research Council and Science Foundation, and currently sits on the Naval Research Advisory Committee and the Defense Threat Reduction Agency Science and Technology Panel. Dugan earned her doctorate in mechanical engineering from the California Institute of Technology and her master’s and bachelor’s degrees from Virginia Tech. …”
ComputerWorld has an article on the “nosql” movement and a recent nosql meetup held in San Francisco, No to SQL? Anti-database movement gains steam. Nosql systems are distributed, non-relational data stores that typically use a simple key-value approach to indexing and retrieving data and use a simple procedural query API rather than a sophisticated declarative query language.
“The inaugural get-together of the burgeoning NoSQL community crammed 150 attendees into a meeting room at CBS Interactive. Like the Patriots, who rebelled against Britain’s heavy taxes, NoSQLers came to share how they had overthrown the tyranny of slow, expensive relational databases in favor of more efficient and cheaper ways of managing data.
“Relational databases give you too much. They force you to twist your object data to fit a RDBMS [relational database management system],” said Jon Travis, principal engineer at Java toolmaker SpringSource, one of the 10 presenters at the NoSQL confab (PDF). NoSQL-based alternatives “just give you what you need,” Travis said.”
There were presentation on nine different ‘nosql’ databases: Voldemort, Cassandra, Dynomite, HBase, Hypertable, CouchDB, VPork, MongoDb as well as general presentations by Google’s Jonas Karlsson, and Cloudera’s Todd Lipcon.
Johan Oskarsson of Last.fm wrote a debriefing post on his blog.
“The relatively young but rapidly growing “nosql” community met last Thursday in San Francisco. The idea was to give attendees a solid introduction to how distributed, non relational databases work as well as an overview of the various projects out there.”
I learned of this meeting on Hacker News, where you can find some interesting comments.
Of course their are many popular key-value stores that are not designed to support the highly-scalable distributed needs of many Web applications. I found, for example, that as a persistent RDF store for rdflib, Sleepycat out performed MySQL.
FaceBook is changing how it manages privacy starting today. After reading last week’s post on the FaceBook blog, More Ways to Share in the Publisher, and a followup note on ReadWriteWeb, A Closer Look at Facebook’s New Privacy Options, I thought I understood: Facebook was sharing more but only for people who have made their profiles public. From the official FaceBook post:
“We’ve received some questions in the comments about default privacy settings for this beta. Nothing has changed with your default privacy settings. The beta is only open to people who already chose to set their profile and status privacy to “Everyone.” For those people, the default for sharing from the Publisher will be the same. If you have your default privacy set to anything else—such as “Friends and Networks” or “Friends Only”—you are not part of this beta.”
“By default, all your messages on Facebook will soon be naked visible to the world. The company is starting by rolling out the feature to people who had already set their profiles as public, but it will come to everyone soon. You’ll be able each time you publish a message to change that message’s privacy setting and from that drop down there’s a link to change your default setting.
But most people will not change the setting. Facebook messages are about to be publicly visible. A whole lot of people are going to hate it. When ex-lovers, bosses, moms, stalkers, cops, creeps and others find out what people have been posting on Facebook - the reprimand that “well, you could have changed your default setting” is not going to sit well with people.”
But it will come to everyone soon! That’s a big change if true. There will be blood.
I hope that there is come clarification soon from FaceBook. I, for one, am left confused.
Should the nations of the world work toward a treaty banning or at least limiting cyberwars? If we don’t, might we fall into an arms race that could be bad for everyone? Would A war in cyberspace be less dangerous for people than traditional wars? Or maybe worse?
“The United States and Russia are locked in a fundamental dispute over how to counter the growing threat of cyberwar attacks that could wreak havoc on computer systems and the Internet. Both nations agree that cyberspace is an emerging battleground. … But there the agreement ends. Russia favors an international treaty along the lines of those negotiated for chemical weapons and has pushed for that approach at a series of meetings this year and in public statements by a high-ranking official.
The United States argues that a treaty is unnecessary. It instead advocates improved cooperation among international law enforcement groups. If these groups cooperate to make cyberspace more secure against criminal intrusions, their work will also make cyberspace more secure against military campaigns, American officials say. “We really believe it’s defense, defense, defense,” said the State Department official, who asked not to be identified because authorization had not been given to speak on the record. “They want to constrain offense. We needed to be able to criminalize these horrible 50,000 attacks we were getting a day.”
Russia has some specific proposals that it would like to have considered. But there are complications that arise due to cybercrime and Internet censorship.
“In a speech on March 18, Vladislav P. Sherstyuk, a deputy secretary of the Russian Security Council, a powerful body advising the president on national security, laid out what he described as Russia’s bedrock positions on disarmament in cyberspace. Russia’s proposed treaty would ban a country from secretly embedding malicious codes or circuitry that could be later activated from afar in the event of war. Other Russian proposals include the application of humanitarian laws banning attacks on noncombatants and a ban on deception in operations in cyberspace — an attempt to deal with the challenge of anonymous attacks.
…
But American officials are particularly resistant to agreements that would allow governments to censor the Internet, saying they would provide cover for totalitarian regimes. These officials also worry that a treaty would be ineffective because it can be almost impossible to determine if an Internet attack originated from a government, a hacker loyal to that government, or a rogue acting independently.”
The article makes the interesting revelation that this is not the first time that cyberspace arms control have been discussed between the US and Russia.
“In 1996, at the dawn of commercial cyberspace, American and Russian military delegations met secretly in Moscow to discuss the subject. The American delegation was led by an academic military strategist, and the Russian delegation by a four-star admiral. No agreement emerged from the meeting, which has not previously been reported. Later, the Russian government repeatedly introduced resolutions calling for cyberspace disarmament treaties before the United Nations. The United States consistently opposed the idea.
… John Arquilla, an expert in military strategy at the Naval Postgraduate School in Monterey, Calif., who led the American delegation at the 1996 talks, said he had received almost no interest from within the American military after those initial meetings. “It was a great opportunity lost,” he said.
This week the BBC had a story about the UK’s cyber security programs, UK ‘has cyber attack capability’, with this video interview with Gordon Brown.
The article leads with this surprising discussion of the UK’s offensive capabilities.
“The UK has the ability to launch cyber attacks but does not use it for industrial espionage like some other countries, minister Lord West has said. He refused to be drawn on whether it was used for military purposes.
…
He told BBC Radio 4’s PM programme the UK faced coordinated Huber attacks “on a regular basis” from other countries including Russia and China. And he confirmed that the British government had approached the Russian and Chinese governments to ask them to stop the attacks. “We have had a dialogue with them in the past and I wouldn’t want to go into what goes on in terms of debate at the moment,” he told the BBC.
…
Pressed on whether Britain used cyber attacks itself, he said: “We do not go and attack other nations to try and find from them their industrial secrets.” But he added: “I think it would be very silly of any nation not to have an ability to use cyber space for the safety and security of its nation.” Pressed further on Britain’s cyber warfare capabilities, he said: “We have an ability to do things and we have got very good and very talented people who have worked on this.”
The article also quotes Lord West, the UK’s first cyber security minister, as saying that they had recruited “a team of former hackers for its new Cyber Security Operations Centre” at GCHQ.
“They had not employed any “ultra, ultra criminals” but needed the expertise of former “naughty boys”, he added. “You need youngsters who are deep into this stuff… If they have been slightly naughty boys, very often they really enjoy stopping other naughty boys,” he said.

“June 26, 2009: Today our team submitted our solution to the Netflix Prize, resulting in a score of .8558, which corresponds to an improvement over Netflix Cinematch algorithm of 10.05%. This is the first submission in the competition to break the 10% barrier and sets off a 30 day period where all competitors are invited to submit their best and final solutions.
The prize is the award by Netflix for an open competition that started in October 2006 for the best collaborative filtering algorithm predicting user ratings for films from a database of previous ratings. Today the BellKor’s Pragmatic Chaos team submitted an entry that improved on the existing algorithm by 10.05%, exceeding the 10% improvement threshold required of a winner. The team is a collaboration between people from Pragmatic Theory, Commendo, Yahoo and AT&T.
“The Netflix Prize seeks to substantially improve the accuracy of predictions about how much someone is going to love a movie based on their movie preferences. Improve it enough and you win one (or more) Prizes. Winning the Netflix Prize improves our ability to connect people to the movies they love.”
Wired’s Threat Level has another example of how social media are being used by Iranian citizens trying to promulgate their cause in Google Maps Track Iran Protests.
“As the protests in Iran continue for the second week, a Google user named Xárene Eskandar is following the activity on a Google Maps page, logging the events each day as they’re reported.
The latest map from Wednesday tracks events by the hour and shows the movement of special forces vans and military helicopters as they close in on protesters, as well as the location where protesters have reported seeing or hearing gunshots.”
The NYT reports in New Military Command for Cyberspace that the DoD has put NSA in charge of a unified U.S. Cyber Command to oversee the protection of military networks against cyber threats.
“Defense Secretary Robert M. Gates on Tuesday ordered the creation of the military’s first headquarters designed to coordinate Pentagon efforts in the emerging battlefield of cyberspace and computer-network security, officials said. Pentagon officials said Mr. Gates intends to nominate Lt. Gen. Keith Alexander, currently director of the National Security Agency, for a fourth star and to take on the top job at the new organization, to be called Cybercom. The new command’s mission will be to coordinate the day-to-day operation — and protection — of military and Pentagon computer networks.”
CYBERCOM will be a subordinate unified command under the US Strategic Command.
“Today, the Google-Facebook rivalry isn’t just going strong, it has evolved into a full-blown battle over the future of the Internet—its structure, design, and utility. For the last decade or so, the Web has been defined by Google’s algorithms—rigorous and efficient equations that parse practically every byte of online activity to build a dispassionate atlas of the online world. Facebook CEO Mark Zuckerberg envisions a more personalized, humanized Web, where our network of friends, colleagues, peers, and family is our primary source of information, just as it is offline. In Zuckerberg’s vision, users will query this “social graph” to find a doctor, the best camera, or someone to hire—rather than tapping the cold mathematics of a Google search. It is a complete rethinking of how we navigate the online world, one that places Facebook right at the center. In other words, right where Google is now.”
This is definitely a David and Goliath match, what with Facebook not having turned a profit yet. The article does a good job of pointing out how their services are different and complement one another.
At the risk of evoking discredited stereotypes, maybe Google is from Mars and Facebook is from Venus.
“As Web-enabled smartphones have become standard on the belts and in the totes of executives, people in meetings are increasingly caving in to temptation to check e-mail, Facebook, Twitter, even (shhh!) ESPN.com. But a spirited debate about etiquette has broken out. Traditionalists say the use of BlackBerrys and iPhones in meetings is as gauche as ordering out for pizza. Techno-evangelists insist that to ignore real-time text messages in a need-it-yesterday world is to invite peril.”
Professors have been dealing with this for several years, since most of our students come to class with their laptops. Maybe they are taking notes. But why is he smiling? Now he’s laughing! Was my comment on hill climbing really that funny?
Of course, the dynamics of this is different outside the classroom.
“In many professional circles, where connections are power, making a show of reaching out to those connections even as co-workers are presenting a spreadsheet presentation seems to have become a kind of workplace boast. Mr. Brotherton, the consultant, wrote in an e-mail message that it was customary now for professionals to lay BlackBerrys or iPhones on a conference table before a meeting — like gunfighters placing their Colt revolvers on the card tables in a saloon. “It’s a not-so-subtle way of signaling ‘I’m connected. I’m busy. I’m important. And if this meeting doesn’t hold my interest, I’ve got 10 other things I can do instead.’ ”
