Crackdown on Military Emails and Blogs
Army Regulation 530-1 Operations and Signal Security (OPSEC)
Dated April 19, 2007, 79 pages
Applies to military personnel, government contractors, and family members
Relevant Paragraph: 2-1g
Consult with their immediate supervisor and their OPSEC Officer for an OPSEC review prior to publishing or posting information in a public forum.
This includes, but is not limited to letters, resumes, articles for publication, electronic mail (e-mail), Web site postings, web log (blog) postings, discussion in Internet information forums, discussion in Internet message boards or other forms of dissemination or documentation.
Supervisors will advise personnel to ensure that sensitive and critical information is not to be disclosed. Each unit or organization’s OPSEC Officer will advise supervisors on means to prevent the disclosure of sensitive and critical information.
There is some leeway in enforcement of the rules. Some units may require that soldiers register their blog with the unit for identification purposes with occasional spot checks after an initial review. Other units may require a review before every posting.
Blogs and emails have become an important support mechanism for the military
Just Google (military blog, milblog, soldier blogs) to find more links
I was moved by these blogs and by the responses posted by readers
Most blogs were created as a way to communicate with family and friends in an efficient manner.
Unfortunately more than family and friends read them
Mercury May Have Molten Core
This discovery was based on the fact that a sphere with a molten core spins differently than one with a solid core.
Mercury is the closest planet to the sun
Jean-Luc Margot, assistant professor of astronomy at Cornell University, and collaborators conducted a series of observations over five years using a novel technique to detect tiny twists in Mercury’s spin as it orbits the sun.
The twists, called longitudinal librations, occur as the sun’s gravity exerts alternating torques on the planet’s slightly asymmetrical shape.
They found that the magnitude of the librations was double what would be expected for a completely solid body — but explainable for an object whose core is molten and not forced to rotate along with its shell.
The impact of a liquid core can be seen by spinning a raw egg and an hard boiled egg.
Spinning an egg is used by chefs to tell whether an egg is hard boiled or liquid inside.
What do you think is the difference between the two is when they both are spun, stopped suddenly, and then released.
Getting a Job without Experience – The Chicken and the Egg (Continuing Story)
We are going to start a career section that addresses the age old problem: "I can’t get a job without experience and I can’t get experience without a job." So what comes first: The Job or the Experience? This is the classic chicken and egg problem. What comes first: The Chicken or the Egg?
