40 Years Ago Today, the World Saw Its First Personal Computer


Engelbart demoIn a convention hall 40 years ago today, a computer scientist took to the stage and blew the crowd away with a couple of screens and the world’s first computer mouse. In a presentation that was later dubbed the “mother of all demos,” Stanford researcher Douglas Engelbart showed off his lab’s research project: the first personal computer, complete with a mouse and an interactive screen.

The invention featured rudimentary windows and hyperlinks that allowed jumping from one document to another, as well as the ability to edit text and add graphics on a video monitor. The presentation also offered a peek at future computer networks that would become the Internet [San Francisco Chronicle]. At the end of the demonstration, the crowd rose in a standing ovation. Today, an event at Stanford will honor the 83-year-old Engelbart and commemorate his moment of glory.

Is the U.S. Government Losing the Battle Against Hackers?


hackingSophisticated computer hackers are as big a threat to the United States as weapons of mass destruction and global jihad, argues a new report on cybersecurity. The report, which was produced by the Center for Strategic and International Studies, a Washington think tank, contains recommendations for the incoming Obama administration, and issues a dire assessment of the government’s current efforts to prevent cyberattacks. “America’s failure to protect cyberspace is one of the most urgent national security problems facing the new administration that will take office in January 2009,” the report states. Cyber safety is “a battle fought mainly in the shadows. It is a battle we are losing” [DailyTech].

The federal government has been embarrassed in recent years by intrusions into the computer networks of many different agencies, including the Defense, State, Homeland Security, and Commerce departments, the National Aeronautics and Space Administration (NASA), and the National Defense University. An investigation last year by The Washington Post showed that multiple compromises of unclassified computer systems for the Transportation Security Administration and DHS headquarters went unnoticed for months in 2006 because the agency failed to effectively monitor its own networks [Washington Post]. In some cases the breaches have been linked to Chinese computer servers, indicating a possible convergence between hacking and espionage.

Beware of Bogus Clinics Offering Stem Cell Cures


stem cells greenClinics around the world are offering unproven stem cell treatments to desperate patients with diseases like Parkinson’s and multiple sclerosis, a new report says, and consumers should be on the lookout for snake oil salesmen. A new set of guidelines issued by the International Society for Stem Cell Research (ISSCR) gives consumers some hints on how to identify the scammers: Beware, it warns, of clinics claiming to treat multiple diseases with the same cells, boasting that there is no risk, and offering patient testimonials - rather than results from clinical research - as evidence that their treatment works. “Patients want to believe so much that a treatment is helping them that they can convince themselves that is has” [New Scientist], the guidelines caution.

In an accompanying study in the journal Cell Stem Cell, researchers examined the direct-to-consumer advertising that shady clinics use to attract customers. They looked at 19 Web sites that advertised stem cell treatments in several countries, including China, Mexico, and Russia, suggesting that stem cell clinics are becoming a lucrative part of the “medical tourism” industry. Researchers wrote: “The average cost of a course of therapy among the four websites that mentioned costs was $21,500, excluding travel and accommodation for patients and care givers. And examples of serious treatment side effects can be found” [Reuters] for the types of treatments being advertised.

NASA Sends First Space-Mails via New “Interplanetary Internet”


interplanetary internetNASA engineers have finally tested an “interplanetary Internet” that could be crucial for future communications with rovers and astronauts exploring the moon, Mars, or other planets. NASA says the system would rely on probes and orbiters to serve as relay stations, or routers, to send communications around the solar system. The space agency has been working for 10 years on the project with Vint Cerf, one of the Internet’s key inventors and now chief Internet evangelist for Google [AP].

The protocols (the language computers use to speak to each other) used for our terrestrial Internet won’t work for deep space, because they assume that the network’s nodes will be connected continuously, and that messages will travel swiftly. But communication between objects in space are frequently disrupted by solar storms and obstructing planets, and sending a message from Earth to Mars can take up to 20 minutes. So engineers at NASA’s Jet Propulsion Laboratory worked with Cerf to come up with a new protocol, called Disruption-Tolerant Networking (DTN).

With the new communications design, each network node is designed to hold onto data packets, instead of discard them, until a destination path can be found. “The incentive to use Internet-like protocols over space links was to take advantage of automated routing,” [said NASA’s Leigh Torgerson]. “With standard space-link communications, the ground sends commands to spacecraft to tell it what time and what data to send. It’s very hands-on-intensive” [Computerworld].

For the Greater Good, Ten Pioneers Will Post Their Genomes on the Internet


DNA double helix 3Ten intrepid genetic explorers have volunteered to have their genetic information posted on the Internet for anyone’s perusal, along with photographs, their disease histories, allergies, medications, ethnic backgrounds and a trove of other traits, called phenotypes, from food preferences to television viewing habits [The New York Times]. The 10 volunteers are the first participants in the Personal Genomics Project, an endeavor run by Harvard Medical School that hopes to offer free genetic testing to 100,000 people in exchange for their privacy.

The project aims to advance genome research by tapping volunteers who have a Facebook-mentality sense of privacy–minimal–and enough excitement about genomic science that they are willing to lay out their genetic and medical information so any researcher can sift through it for links between genes and traits. “There’s a hope that by making these data public, you can harness crowd-sourcing power in the same way that Wikipedia and YouTube and Google and Linux all emerged from cooperative, distributed efforts” [Boston Globe], said Harvard psychology professor Steven Pinker, who is one of the 10 pioneers.

Google Satellites Aim to Bring High-Speed Internet to All of Africa


Africa computersGoogle has backed a venture to use satellites to bring high-speed Internet to three billion people in Africa and other developing markets around the equator. Today Google announced a partnership with cable operator Liberty Global and bank HSBC. Their partnership is called O3b Networks—O3b stands for “other 3 billion,” a reference to the world’s population that still can’t access the Internet [The New York Times].

The group announced an order for 16 satellites as the first stage in the $750 million project, which will provide cheap, fast Internet access to companies that sell internet service via mobile phones or wireless networks. The move is being greeted as a clever technological solution, a boon for the developing world, and a smart business move. “Google has an interest in boosting the Internet all over the world to reach new masses,” said [business analyst] Wim Zwanenburg…. “The growth market for Internet and mobile phones is in emerging countries” [Bloomberg].

Wi-Fi in the Sky: Delta Adding Internet to All U.S. Flights

DeltaAirfare prices are soaring, and airlines have tried to cope by charging for food, drinks, and other formerly free items. But there’s one bright spot on the horizon: Passengers may soon be able to access the Net during flights—although you’ll have to pay for that, too.

Delta Airlines says it will beginning offering Internet access on some flights beginning as early as October, and plans to outfit the entire domestic fleet with Web capability by next summer. Fliers with Wi-Fi-enabled devices like laptops, smartphones and personal digital assistants will be able to access the Internet while in flight. The service will cost $9.95 on flights of three hours or less, and $12.95 on longer flights [The New York Times].
