Last year I upgraded my home network to something faster than 802.11b. Even though my cable internet provider is providing download speeds significantly lower than the about 5 mpbs transfer speeds I get with 802.11b.
So why did I upgrade? Because I do a lot of large file transfers between computers on my home network. I have done some contract work setting up networks for small businesses where they also have to transfer large files between servers and workstations. A wireless standard that transfers files as fast as 100 megabit ethernet will cost my clients more for hardware, but they will no longer have to pay for somebody to come in and install cat 5 cable for all the notebooks.
If the debris were being accelerated it would trade velocity for altitude, moving into higher orbits until it eventually was ejected from earth orbit. The orbital debris does not need to be accelerated any faster than it is already moving to cause damage. At 300 km, an average space shuttle orbital altitude, an object would be moving almost 17,300 mph to maintain altitude. Objects in high inclination orbits could impact almost head on; at a 34,600 mph differential velocity even a paint chip can cause serious problems.
What really happens is that over time objects slow down. As they slow they fall into lower orbits and are accelerated, but not quite enough to maintain the lower orbit. As the objects get lower, atmospheric drag increases and further slows the object. In time the orbit degrades to the point where atmoshperic drag slows the object enough to fall to earth, or heat from friction with the atmosphere vaporizes the object.
Here in The US, a technologically above-average country, classroom technology is going to waste because the college educated teachers are too lazy or not smart enough to learn how to apply the technology.
In a poor third world country, where the standards are significantly lower for instructors, who expects the students and instructors will somehow instinctively know how to use these computers for educational benefit? If they are networked the kids will very quickly figure out how to IM answers during tests, but only if they first learn to type.
Every Marine shoots from the 200, 300, and 500 yard lines. Because the 500 yard line is slow fire from the prone position, I and most of the Marines I served with thought the 500 yard line was the easiest stage.
He may be an average Marine marksman, but the average Marine is far better than the average Anonymous Coward.
When I was pursuing a computer science degree, I took the heaviest class load I could handle and finished as fast as I could. This left almost no time for work, and in probably any other field would have implied to HR that I was hungry to get into the workforce. I graduated in August 2001 and have yet to find a job in the computer field, but the people who took five or six years to earn their degree instead of three were able to claim experience through their internships or side jobs and get good offers.
These days a lot of the entry level jobs I see posted require 1-3 years of experience - as I said, experience for an entry level job. So I have become a firm believer that, with the exception of an elective class that may be relevant, the CS classes you take in pursuit of your degree do not matter. As many others have said, there is a big difference between academic exercises and professional programs.
Put in the minimum work necessary to get good grades and recommendations from your instructors. Then use all the extra time you have to find jobs or summer internships and put as much experience as you can on your resume.
You had to drag your desktop to school? I guess I was really lucky to have my Osborne 1. Of course at 25 pounds it was heavier than the textbooks I would have put in my backpack, it needed a giant sized custom backpack to be carried, and it didn't have a battery so it had to be plugged in. But it was cheaper than the Dell notebook I am using right now, and it sure was a lot nicer than the used TRS-80 computers my high school had!
Before the a-bomb, Japan had thought of itself as largly protected from invasion
Can you confirm that? I would expect Japanese attitudes of invincibility and superiority would have started evaporating when Jimmy Doolittle lead his famous Tokyo raid in 1942.
I, too, am finishing a CS Master's. And outside of government I find very few recruiters who will seriously consider an MS candidate over an experienced BS candidate. As others have said, the corporate world is very different from academic projects, and most of the recruiters I have dealt with consider a Master's candidate somehwere between a BS new grad and BS with one year of experience.
I live just south of the border so I get to see how two different countries do it on a regular basis. In Canada internet access seems to be treated like any other public utility, broadband is easy to access, and it is priced affordably.
Compare to this part of the US where companies charge around $50 per month for broadband and act like they are doing us a major favor by only charging double what I pay for phone service or water and sewage on a monthly basis.
The table of contents doesn't mention linear or differential cryptanalysis of a substitutation permutation network, and even if it did nobody is going to decrypt DES or AES on paper.
But in a place like Iraq, where power is unreliable and an endless supply of batteries for handhelds is not available, the enemy will have to rely on non-electronic cipher equipment.
Of course the problem in Iraq is that they don't use the English alphabet or language. The frequency analysis we depend on for the shift cipher or Vigenere cipher doesn't work for Arabic.
And even if they did, I really don't want to try and crack a Vigenere cipher without a computer!
Can you tell us where the jobs are? As a new graduate, in the last three months I have been rejected for programming jobs in all 50 states, three territories, and four other countries. All the companies that replied rejected me because I am "underqualified". And I have been rejected from non-computer jobs in 38 states - it seems that if you have a CS degree people offering $35,000 per year think you are "overqualified."
While being rejected because I don't have years of industry experience, people I know who work at some of these companies tell me they are hiring foreigners straight out of school with absolutely no professional experience.
Most people I know really don't resent immigration - they and I only resent immigration when unemployment is an issue. Some economists are forecasting economic problems for the US in about 10 years when the baby boom generation starts retiring en masse, but I have never met anybody who thinks we should restrict immigration when the immigrants will be necessary to the economy.
I have friends working at companies that hire a lot of H-1B workers, and they tell me the Indians are straight out of school. But these companies will not consider any Americans without a great deal of experience, setting a double standard for Americans and Indians.
To unemployed programmers - people who were laid off and had to train their H-1B replacements or new graduates who are told the only new graduates who are qualified come from other countries - it really doesn't matter how much money foreign tech workers spend while here. It just matters that the foreigner can spend money and the unemployed programmer has no money to spend.
Disagree? Try losing your job, spending about a year being told you are underqualified in the computer industry and overqualified in other fields, and see how you feel when companies that will not consider you tell Congress they need more foreign tech workers.
Companies claim they can't find qualified candidates, and techies claim above average unemployment. Since some companies seem to define qualified as either 5+ years experience or new graduate of an Indian tech school, they are being honest about not finding people who meet their qualifications.
I would hope that every unemployed programmer, and everybody concerned about losing their job, will write to their congressman describing unemployment in the field so that subject can come up when companies do get a hearing to increase the H-1B cap.
I am level 2 certified through the National Association of Rocketry and Tripoli Rocketry Association. I have rockets, built from kits purchased for under $200 and propelled by
solid fuel motors for around $200 or
hybrid motors for about $100 that can carry a 0.5 pound payload far higher than one kilometer.
Anybody on this list who is willing to take a few evenings to build a rocket kit, spend the money to join NAR or TRA, and join the nearest high power rocketry club will be able to launch a small TV transmitter with telemetry over one km and save $18,000 over the Japanese liquid rocket.
And if you are really into liquid fuels, you can even find amateurs working with those.

As many have stated, this is old news. What is really surprising to me is that when I enter my ham callsign I do not get a lookup option.
