Alsoluty true. I was strictly speaking from the US point of view, which is what most of the thread related to.
Of course, I think the probability of someone without a space presence, having the technology to use conventional weapons in space, and hit anything, or be big enough to effect much, and be high enough to have an effect before the debri reentered, would be highly unlikely.
Way too many posts about "conventional" space weapons.
If this was what the US wanted to build, cost would not be much of an issue. This wouldn't be the weapons developed for the very reasons you suggest.
There are already weapons against satellites used by many enemies and allies, just not physical, although some can cause permanant physical damage. (Think jammers, RF overload, etc.)
New weapons yet to be anounced would most probably just de-orbit satellites or capture them and point or move them elsewhere. (There are systems for this already. Just not advertised for military use.)
Using conventional weapons would destroy the US satellites as well. That won't happen (hopefully).
Do we really want to militarise against our friends, diverting funding from protecting against clear and present and active offensive enemies?
Yes you do, and the US already does (as does everyone else.) There is a saying, "There are no friendly coutries, just countries with common interests." And when those interests change, the
"allies" will switch sides to protect their interests. (Remember France?)
Any major country with an intelligence agency keeps tabs on their allies (and enemies). In the US case, the allies are the ones with with the biggest capabilites to keep an eye on if the tide was to change.
True. GPS doesn't use leap seconds EXCEPT to convert to UTC. (Probably why the epoch is UTC based.) Since most all user displays use UTC or local time, the end user units would need updating, or the leapsecond value/field would exist forever as a legacy item.
(The GPS system does distribute the leap second count and most all receivers provide UTC time based on this value.)
The thing that struck me the most is they claim GPS systems solve the need for tracking stars.
Anyone that has been involved with developing GPS software (or most any satellite system) knows that GPS time uses the leap second value to convert from UTC time (GPS Time = UTC Time + leap seconds since epoch)
So... to drop leap seconds would mean GPS time would also have to be changed.
"Hyper-Threading Technology makes a single physical processor appear as multiple logical processors [11, 12]. To do this, there is one copy of the architecture state for each logical processor, and the logical processors share a single set of physical execution resources."
And:
"Logical processors share nearly all other resources on the physical processor, such as caches, execution units, branch predictors, control logic, and buses."
The HT processors take advantage of the idle time in one thread by allowing the other thread (logical processor) to use the core. There is only one core and hince NOT true SMT. You can only have true SMT by having multiple cores.
Actually, HT is not "simultaneous multithreading". Intel added extra hardware registers, etc, to make switching threads faster. HT still is a single threaded processor.
This already exists. It is illegal to distribute classified data no matter how you get it. If you know that you are tracking secret payloads and distributing the data you are already violating the law.
The best solution is to work for term limits for all positions in Government. It's suppose to be Government for the people, BY the people. Term limits would get rid of the career politicians and put a dent in the special interests groups hold on the career men.
Interesting. I hate to see MORE of the serial and parallel ports disappearing.
As a embeeded systems developer, I NEED serial and parallel ports to interface with hardware. I already have a hard time with the one serial port the ATX machines have now.
We constantly have to buy add on cards and USB to serial converters.
We need a macroBTX form factor for those of us that need all the extras. You would think those guys at Intel would understand.
I'm not as familar with the details of the production process, but from what I understand, the pollution is mostly due to energy needed that is created by fossil fuel plants.
One would think that overtime, as solar power increased, the dependance on these external sources would decrease.
BTW, I don't know of any natural hydro power plants created without big heavy pollution generating trucks and material plants.
A few years ago, the local phone company was expanding their infrastructure to include cable and internet service. The distribution system involved putting little buildings in neighborhoods where the phone company ran high speed fiber lines. From there they split out the normal phone and cable lines.
Since we lived just 200 ft from the building, I asked them if they ever planned to run fiber to the homes instead of having to use copper for internet. The told me that would never happen because fiber optics cause cancer!
BTW: Carrying your SS Card in your wallet is just asking for trouble. You rarely NEED that card and it should be keep in a safe place no one else knows about.

Federal contractors are still required to have an affirmitive action program. http://www.dol.gov/esa/regs/compliance/ofccp/aa.ht m
This general means these companies have had to prove compliance and keep track of this data.
Yeah, it already exists. Google for Solar Power...
Pick the Apollo 16th site and zoom in, all the way...

Not impossible, but unlikely.

This has been done for years via APRS. http://www.aprs.net/ http://web.usna.navy.mil/~bruninga/aprs.html It would be much nicer if there was a Google Maps interface for this.
"This is achieved by duplicating the architectural state on each processor, while sharing one set of processor execution resources."

Believe me, this site is missing the interesting ones...

Now that'd would be news.

Of course this is too easy but... Just use a standard Window AC Unit and put the PC in a box...

Also, solar panels. I'm still waiting for the price to be reduced enough to put one one every home/business.
This is done often for commercial and residential homes. Search web for geothermal air conditioning.

Actually, there are many older Military Payloads on orbit. Here is one article.
