"Witty" Worm Attacks Fermilab Computers Late on the night of Friday, March 19, the so-called "Witty" worm was let loose on the Internet and attacked Windows computers running the BlackIce personal firewall software. This event represents an escalation of the computer virus threat in two ways. First, the attack came less than two days after the vulnerability (and the patch) were publicly disclosed. Second, this attack was designed to destroy random data on victim machines.
The attack, being automated, developed in minutes, while incident
reponse, by experts from Business Services and Computing, moved on a
human timescale of hours.
Sixty-nine seconds after the attacking packets began to cross the site
border, the first Fermilab machine fell and joined the attack. The
final count of infected systems was 84. Our network defenses worked as
designed, stemming the intensity of the attack somewhat, and greatly
reduced the impact of our infected systems on the rest of the lab
computers. Thanks to the dedicated employees who spent Friday night and
the weekend to fix the affected systems.

From Wired Magazine, April 2004 The God Particle and the Grid 200 feet underground, a proton does 17-mile laps at nearly the speed of light. Guided by powerful magnets, it zooms through a narrow, circular tunnel that straddles the Switzerland-France border. Then a tiny adjustment in the magnetic field throws the proton into the path of another particle beam traveling just as fast in the opposite direction. Everything goes kerflooey.
This will happen 10 million times a second inside the Atlas detector, part of the Large Hadron Collider now under construction at CERN, the famed European particle physics lab outside Geneva. When the LHC is finished in 2007, it will be the largest accelerator in the world. Massive superconducting magnets cooled to near absolute zero by liquid helium will bend 20 micron-wide beams of protons into precise trajectories and crash them into each other.

Safe Bicycle Riding | ||
| ||
|
A number of Fermilab employees ride their bikes to and from work
on a regular basis. With warmer weather on the way, we can only
expect these numbers to increase. Riding a bike is a great way
to have fun exercising, and it is an environmentally-friendly
form of transportation. Even though Fermilab is often described
as a "bicyclist's paradise" because of its well-maintained paths
and low motor vehicle traffic, bicycling can also be an easy way
to get hurt.
Every year in the United States, more than 580,000 bicyclists receive emergency room treatment, 20,000 are admitted to hospitals, and 900 are killed. Motor vehicles are involved in 90% of bicyclist deaths. Defensive riding behaviors and use of safety equipment are the keys to safe biking. Wearing a bicycle safety helmet is probably one of the best things that you can do to protect yourself from injury. (The hat-head goes away after a little while.) Also, obey all traffic signs and signals -- Fermilab's site is no exception. Some other bicycle safety tips to keep in mind are:
Have a great day and let's work safely all week!
