Comment Re:Why not Mach 22 (Score 1) 221

Nope, you're dead wrong on all points. Flight is far more efficient than a ballistic trajectory. Being in an atmosphere is actually really great because wings allow you to lift far more weight than your engines themselves are capable of. And there's no way to 'glide' in space.

Maybe you lack some understanding here. Take the international space station. It is using almost no fuel as it moves along at Mach 22. If you lower it into the atmosphere, and add wings to it, you will use a lot more fuel to keep it flying.

Why not Mach 22

If you first want to go fast, why not just use an intercontinental ballistic missile? It is really simple construction (read fuel tank with orifice), uses cheap fuel, and really need no fancy aerodynamics or control system. Just aim and fire.

The whole idea of pushing a vessel through air for hours and hours, wasting fuel, when it can glide with no friction a few miles higher seems dumb. It also consumes more fuel in total.

Comment Re:10 Mbits isn't enough (Score 3, Informative) 280

If you have 50Mbs you will not have any problems with decent video while playing a game. If you do, the problems must be somewhere else. Your hardware or network congestion/configuration, or many of you family members is watching porn in 4k 3D without your knowledge.

Netflix bitrate for 4k video is 15.6Mbps. Games are mostly under 0.5Mbps. If you run a game server, you may need more than 0.5Mbps.

Account should not try to "get knowledgeable" in HTML and JavaScript. He will only seem more of an idiot.
1. Be a great accountant, and dominate your existing field. Teach developers how to make the products more profitable
2. Be a human and a user, and gain user and interface expertise, so you can say what you think about the product with authority and clarity. Tell the developers how to make a more usable product.
3. Can your expertise be used to improve the product? Accounting skills may be important for the platform to make money, and the financial analysis tools needed to understand the web platforms performance.

Comment Absolutely no useful information. (Score 1) 62

No information on bandwidth, signal strength, channel separation or anything else. Only that it "acts like a concert conductor".
How low can a scientific article sink, and still be the basis for a slashdot story? This must be a new low.

Current trans oceanic fibers do transmit multiple colors at high speed with amplifiers on the seabed and no regenerators. New installations carry 64 Tb/s per fiber. and often 64 fibers are laid. Some are left dark, but theoretical capacity for a cable is therefore 8192 TB/s bidirectional capacity

This might be up to 8 billion HD channels or everyone the entire earth watching different TV channels at the same time. Not sure how much more bandwidth is needed in a cable.

Comment Habitat trumph science: Arab backyard Mars-like (Score 1) 190

What arabs lack in sceitific strength, they have in life experience. Mars is a dry desert, and nobody knows dry desert better than arabs. NASA has to travel far, and no NASA engineer has any experience with climate similar to Mars.
Arabs just need to exit their door, and it is like being on Mars. Huge advantage over both USA as well as Europe, Russia and China.

What is the most complex item you can buy in your local store manufactures in an arab country?

Comment Basic:tedious, user unfriendly, not problem orient (Score 1) 215

Basic as a language is tedious, user unfriendly, and not problem oriented. Java is a lot better. My kids 6. and 8. grade took Stanfords CS101, and I was truly impressed with how fun it was for them, as well as what they could accomplice.

Everything is done right in the browser. Try it out for yourself. Khan academy has tried a "fun game" in java approach, but this is much less focussed and kids seem to tire of it as soon as they have made the limo break the sound barrier.

1. A lot of graphical processing, like finding traffic signs in urban environment (for automatic driving) to bluescreen manipulation.
2. Also building databases and doing datamining.
3. Networking
4. More programming; Digital media, analog, security etc

Comment Darwin never suggested "survival of the fittest" (Score 0) 249

Darwin never suggested "survival of the fittest". What does this even mean? 'Fittest' must mean ' most fit in a certain environment', but how is that measured? 'Most fit' must can only be meaured as the ones 'that survive'. So the statement can only mean "survival of the survivers" which is a trivial obsurdity.
