  1. any technical coursework is engineering in Asia on Mr. President, There Is No (US) Engineer Shortage · · Score: 1

    Its a cultural thing. Parents want their sons to be "engineers". So many vocational, college and business degree programs are called engineering.

    The past several presidents of China have been "engineers" although I believe they've been managers for most of their careers.

  2. oil industry hired a lot of Houston NASA people on Mr. President, There Is No (US) Engineer Shortage · · Score: 1

    I read about some job fairs specifically targeted at this resource.

  3. like "compuer scientist" on Mr. President, There Is No (US) Engineer Shortage · · Score: 1

    Some people complain about adding the word "science" to professions that may be less rigorous science.

  4. glory days of space science b4 tea party kills it on Mars Rover Begins "Whole New Mission" · · Score: 1

    Seven of the nine major planets either have at least one probe working there or in transit to it. Plus a couple in the Asteroid belt. Next week the Grail gravity probe goes to the Moon. And the long-delayed Curiosity Mars Science Lander launches at Thanksgiving.

    The future is less bright. The Hubble replacement Webb telescope is three times is original price, five years late and all but dead in the appropriations committee. Te decadonal report has selected probes for the rest of the 2010s, but none has been formally approved.

  5. Apple enlarged a cellphone; MSFT shrunk a PC on Steve Jobs, Before the iPad, On Why Tablets Suck · · Score: 4, Insightful

    The user interface is more compact on a cellphone, not bloated like on a PC. A fortuitous discovery Steve probably made after 2003.

  6. incorrect on Ask Slashdot: Math Curriculum To Understand General Relativity? · · Score: 1

    GR has some hairy tensor equations that have never been fully solved. You are correct is saying the principle of relativity goes back the Galileo in its most basic terms, just requiring algebra then. SR is not that much harder.

  7. "one man's noise is another signal" on Using GPS To Detect Secret Nuclear Tests · · Score: 1

    As they say in the observation sciences. Its known that the position of ionosphere, humidity, atmospheric charge, etc. can affect GPS signal timing slightly. In turn these erors can be inverted (tomographically) to give maps of these phenomena.

  8. Re:Data centers on Hurricane Irene Threatens US Northeast; Cover Your Assets · · Score: 1

    They been siting them in locations with abundant cheap energy. Unfortunately things that make energy abundant can make it too abundant at times, e.g. hydroelectric.

  9. line between carrier nad content provider on Google Reaches $500 Million Settlement With Feds · · Score: 2

    Telephone companies are legally immune to crimes planned while using their equipment. For most of their history its too difficult to police transmissions. Is an ISP or Google a carrier, content provider or both?

  10. Currently Russian, ESA, & Japan supply ships on Russian Supply Vehicle To ISS Burns · · Score: 1

    And maybe some new private American ones in a couple of years. Only the Russian may be passenger-rated. Most of these are one-way with no shielding to return to earth. You fill with garbage, and jetison into the ocean if it doesnt burn up first.

  11. drop some gizmos like in netbooks on What HP's TouchPad Fire Sale Teaches iPad Rivals · · Score: 0

    Touchscreen, size, color, wireless are important.

    Audio, video, GPS, 3G, phone, camera, could be optional. Mobile devices have been evolving into "swiss army knives". But this may not be necessary.

  12. immediate pleasure of exercise more important on The Least Amount of Exercise Needed To Extend Life · · Score: 1

    It makes me feel good doing it. It makes me look better. It reduces colds and headaches. And its fun at times. Increased longevity is a bonus, but not a deal-maker.

  13. 20 miles equivalent of cardio on The Least Amount of Exercise Needed To Extend Life · · Score: 3, Insightful

    I've heard this expressed in terms of weekly calories expended in heart-raising exercise, i.e 2000. Walking, running, biking (3x miles), etc. doesnt matter so much as long that many calories are burned. Neither whether its compressed into a couple of long sessions or divided into many ten-minute mini-sessions. In fact it recommended to choose the most pleasant form of cardio to you so can you can continue to do to for 50 or 70 more years.

    This data comes from the "grandfather" of the exercise boom Dr. Kenneth Cooper. He wrote a book called Aerobics in 1968 promoting endurance exercise over the then-popular calesthetics. He ignited the running boom by putting the on top of his 60-point-week exercise classification system. Running gets you there in the shortest time.

    Above 2000 exercise calories a week the situation gets murkier. You get additional, but diminishing longevity results up to about 5000 calories (50 miles walking/running). After that the main effect is improve sports performance, not longevity. Dr. Ken even claims that too much exercise may create more oxidative waste than the body can eliminate and then decrease longevity. But this is a minority opinion and irritates the ultra people.

  14. Its very difficult to resolve depth on 5.8 Earthquake Hits East Coast of the US · · Score: 1

    They basicially use over-determined triangulation to calculate epicenter coordinates. When the epicenter is close to the plane of seismometers, the vertical resolution is terrible. So they fix an arbitrary default depth to the quake to calculate lateral position.

    GPS altitude resolution is poor for the same reason.

  15. Mars life probably infected Earth early on on Earth Ejecta Could Seed Life On Europa · · Score: 1

    Being smaller, Mars stabilized geologically before Earth and life evolved there first. Then it probably infected Earth.

  16. Apple has 35 years of hardware experience on Analysis of Google's Motorola Acquisition · · Score: 1

    Apple has always been a premiere hardware company with lucky forays into software now and then (MacOS, iTunes, Apps). Half of Apple's products have been huge best-sellers. Very few hardware companies have a 2nd success. I dont think Page knows what he is getting into.

  17. Is this a "Fourth Wave" of civilization? on The Post-Idea World · · Score: 1

    40 years ago Alex Toffler coined the Third Wave of the knowledge industry, following manufacturing and agriculture. It is unclear whether there anything to follow the third wave.

  18. some social networks do this already on Yahoo, Facebook Test "Six Degrees of Separation" · · Score: 1

    They tell you whether you have any connections in common up to a certain degree.

  19. technically this applied to acting credits on Yahoo, Facebook Test "Six Degrees of Separation" · · Score: 1

    No separation = same movie.
    One degree was with someone who acted with him, etc.

    I supposed IMDB could be topologized to measure two actors' separation.

  20. only two of the 40 tablets out there are selling on JooJoo Maker Is Back With a New Tablet · · Score: 1

    Another "me too" tablet makes me yawn.

  21. 80 hour weeks are bad management and code quality on Ask Slashdot: Am I Too Old To Learn New Programming Languages? · · Score: 1

    Age has little to do with it, save young programmers may have more energy and no social life. Too many hours is sign of a poorly designed project and management inexperience.

  22. may help achieve Kyoto carbon agreement on US Energy Panel Cautiously Endorses Fracking · · Score: 2

    Natural gas has half the carbon footprint of coal or petroleum. A massive shift away from these to to natural gas will reduce US carbon emissions. Plus there s an economic incentive to use gas. Bio fuels and solar require huge government subsidies which may not survive in this era of government cutting.

    The main scientific caveat is methane is a strong greenhouse gas in its own right- twenty times more power per pound than CO2. Its half life-time in the atmosphere is 20 years compared to millennia for CO2. I've seen calculations that if six percent of the natural leaks at production or shipping, then it will cancel its greenhouse effectiveness. There isnt very good data as to current industry leakage rates. Some of the pessimists put at least six percent.

  23. "light behind knees" for jetlag? on Human Brain Is Sensitive To Light In Ears · · Score: 1

    An 1998 article in Science claimed there were photoreceptors there and helped alleviate jet lag. I dont know if scientists have followed this up. But its become urban legend now.

  24. credit card verification? on Fake Names On Social Networks, a Fake Problem · · Score: 1

    I recall some early dating sites used credit cards to verify identity. This doesnt help you to go after the high school crowd which usually dont have CCs in their own name.

  25. I thought humans were mostly virus, countwise on New Drug Could Cure Nearly Any Viral Infection · · Score: 1

    The rule-of-thumb is for every human cell there are 10 bacteria and 100 viruses living together in [ mostly ] symbiotic harmony. But bulkwise, due to miniscule size of these symbiots, bacteria only occupy a couple percent of weight and viruses a fraction of a percent. A tiny minority go berserk or are foreign invaders, thus cause some diseases.

    The question is how does medicine distinguish the between the useful viruses and bad viruses?
