Virgin Galactic Announces New Satellite Launch Vehicle

frith01 charge for launch ! = cost for launch (102 comments)

Some people are thinking that the advertised cost of 10m per 225kg means that his costs are the same as Pegasus. They do not realize that branson would not start in the market at his lowest profitable point. If market price is 20k per kg, but I can do it for 5k, I'll just take the extra profit until the market catches up!

Asteroid the 'Size of a Minivan' Exploded Over California

frith01 Re:Two things holding up asteroid tracking (279 comments)

I would think orbital mechanics plays a part that eliminates markovian analysis. ( ie, large object breaks up into smaller pieces, which stay largely in the same orbital path, hence the perseid's meteor showers :)
Haley's comet as a predictable 75 year orbit, why wouldnt there be stuff with 100, 500, 1000, 10000 year orbits that cross our path ?

D-Wave Announces Commercially Available Quantum Computer

frith01 Re:So how many frames will this get in Crysis? (133 comments)

0 frames in Crysis, this is a math co-processor type deal initially. Just speeds up processing for a specific type of quantum algorithm initially. ( Quantum annealing , min/ max )

LED's Efficiency Exceeds 100%

frith01 Re:Glowing metal (502 comments)

perfectly insulated = no heat transfer = no source of thermal energy for the metal to convert to light. ( after a reasonable equilibrium time point within the container, such that all metal achieves the same temperature.)

Ubuntu TV: Coming Soon To a Living Room Near You (Video)

frith01 Integrated Computers & TV's dont mix (183 comments)

Computer hardware changes a lot faster than the display components. There is only a limited market for integrated devices unless they are strictly re-formatting/ receiving streams over IP.

Of course, manufactures would LOVE for you to buy an Integrated device with TV today, so they can sell you a brand new shiny toy in 3-5 years when your display gear no longer works with DRM version X.

Look at all the VCR / TV combo's sitting in the garage sales cause they dont play DVD's , etc..

US 'Space Warplane' Spying On Chinese Spacelab

frith01 two birds looking at same targets. (158 comments)

Actually, they are probably both in viable orbits to keep an eye on Iran / Afghanistan. Iran doesnt have the range on their ballistic missiles to hit the US yet, but they can sure hit china easy enough.

New Record High Temperature At South Pole

frith01 Detail records since 1950 (387 comments)

previous temp high was in Dec 1978, detail records have been kept since mid 1950's.

approximate annual average temperature records through ice cores date back about 800,000 years.

Why We Agonize Over Buying $1 Apps

frith01 Free works w/o Credit card (523 comments)

I would never attach my Credit card to an app store, due to having a 6 yr old in my house who loves to play with my phone.

Having a threshold at $1 means other developers also wont try to undercut at $0.9 , and drag the whole pile of apps down to $0.05 eventually.

Researchers Demonstrate Quantum Levitation

frith01 Re:TFA is nothing new (133 comments)

You missed the part in the video where they turn the track upside down. If they were only using the meisner effect, the puck would drop to the ground. They have found a way to control the magnetic field more precisely, and pin the object in place. ( ie, a useful example of the engineering techniques now possible with the effect, instead of just ooh, shiny. )

Can Relativity Explain Faster Than Light Particles?

frith01 Re:"Speed" (315 comments)

The article states that because they moved the atomic clock used for measuring time, their time synchronization would be different for the clock while it was in italy, then when the clock was in switzerland. The difference in time synchronization is what they measured, not the speed of light.

Of course, they knew about this effect, & tried to off-set it by using GPS signals from the same satellite to correct. TFA says that GPS signal has error in time sync about 100ns, which is in scale with their measurement error.

CERN Experiment Indicates Faster-Than-Light Neutrinos

frith01 Rotational issue? (1088 comments)

I know they have tried to factor out obvious stuff, but wouldnt the rotation around the sun ( or galaxy) mean that its possible they're hitting a target that's moving "closer" to the source?

Researchers Debut Proxy-Less Anonymity Service

frith01 Re:Looks like port knocking to me, just with param (116 comments)

vpn requires local software / possibly alternate ports to initiate.

Proxies do not require local software, but have central points that can be blocked.

better method would be to have simple looking sites have "backdoors" that could be used to exit normal mode, and establish new session with hidden services.

Researchers Debut Proxy-Less Anonymity Service

frith01 Looks like port knocking to me, just with params (116 comments)

It would be easier to configure a web service which recognized X keyword searches from the same session to convert the session to a port forwarding ssh session to an appropriate proxy.

( google search on book, monkey, tuesday, and blue gets you ssh forwarded to, etc. )

your https connection stays to the main site, & it just forwards the data .

Engineers Find Nuclear Meltdown At Fukushima Plant

frith01 Re:and? (664 comments)

wrong %, they thought only 55 % of the rods had been damaged. with 5 feet of EVERY rod affected, that is 100% , they didnt specify their denominator, so it would be easy to get confused.

Plus, at least 5 feet of the core was exposed until they adjusted the water level TODAY, the water level was much lower during the crisis.

Atomic Weight Not So Constant

frith01 Location of nuke material (147 comments)

Hasnt this always been known that even different mines from the same countries produce isotope "fingerprints" that let the 3 letter agencies identify where nuke material come from? This is simply making it more obvious to those who use the reference for the range of values found so far ?

US Air Force Launches Secret Flying Twinkie

frith01 Re:Speculation in the article (234 comments)

Satellites have a predictable orbit which can be used to avoid surveillance. A non-predictable orbit of the spaceplane allows other devices to be deployed which can have yet another orbit which is very difficult to detect. ( think stealth satellite.) Additionally, imagine something like a HALO drop of a predator in a can, which opens after re-entry.
