I personally think the best IT people are the one that don't do anything all day. They are the ones that did everything right thefirst time. And continue to do things correctly so they don't have to do anything. I would love to have that guy, rather than the guy that is to busy to hand me a replacement computer because my dimm slot is bad.
I am in a similar boat. But while you could be doing more, how long could you do it? Would the quality suffer? Would you request more money?
All of these questions make pushing everything out of you a bad position for your employer. They want a fair amount of work, in a fair amount of time, for a fair wage. Trust me they make a boat load on your 2hrs of work everyday. And they want to keep you around as you are capable of doing 4x (or more) work in short bursts.
You work more, you will need to be paind more.
You work more, you become unhappier and are more likely to leave.
You work more, your quality may suffer.
And when needed, your company can push teh emergecy button and get 4x the work out of you for a couple weeks.
The WTC also was designed to take a hit of a SMALER plane that actually hit them. They were designed to take a 737 (maybe 717) and they had 767s hit them. The planes that hit them were WAY bigger than design.
Yeah but there is a middle ground between Atom and the fastest Core2 you can put into a 'laptop'. You can get low power fast processors and get 4-5 hours of battery easily.
Except the Everglades, Big Cypruss, Timucuan, and Biscayne are FEDERAL LAND. The FEDERAL GOVERNMENT should pay for it. You are also paying for coral reefs off the coast of the Keyes and a bunch of other stuff too. You think that Wyoming should pay for Yellowstone? You think that Wyoming should be able to devolp Yellowstone if they want, to the loss of the rest of the country?
I would think posting words would be covered under free speach. I doubt they are copyrighted. Plus with the internet you can host outside the USA. But I guess that didn't work for The Pirate Bay so who knows.
Hey at least.docx and the other Office file formats are an ISO standard. Open for anyone to implement now.
As for the rest of MSFT software well some you can use, others you cant.
Well yes you can do whatever you want to the OS. But you see the OS doesn't do anything but connect you to Google Docs.
In the article it even states that disk drives, and probably all local storage would not be supported by the OS. So all you data is locked up on Googles severs.
Ok so as a mechanical engineer that does this stuff for a living here is how you would design such a system.
You design a cooling loop of water that cools the data center. You pump water fast enough to remove the amount of heat generated by the data center, and maintain a certain liquid temperature, which will translate to a certain chip temperature.
This water say enters the data center at 20C and leaves at 50C, you can change the temperatures of these by adjusting the flow rate of water (assuming a constant chip loading, in reality this flow rate will change based on temperature probes).
You dump the 50C water into a tank (heat storage vessel, think of it as a battery for heat). You then take this 50C water into a heat pump, this is reversible and such follows carnot cycle laws. This chills water back to 20C (and ready to cool processors), by heating a refridgerant, the refridgerant then heats your hot water city loop, with all the carnot losses ending up as heat in the refridgerant (losses get conserved and used). All your losses end up being used, as they are in the form of heat, and you are collecting WASTE heat.
The reason why your AC unit has to be outside is because of this, the losses incured would end up heating your house instead of cooling it.
Now on to your claims. There is NO reference to a heat engine, or anything that would require knowledge of a Carnot cycle. Thinking about how I would attain higher temperatures you would employ a heatpump (but this pump would contribute ~95%+ of its losses to heat the final fluid).
Ok so keeping chips at 20C isn't realistic, it should be more like 50C. Doing this would rais the efficency of the heat pump required to get higher temperatures. BUT ALL the HEAT would STILL be RECOVERED!
And I am sorry but you will recover (assuming chip surrounded by your heat recovery fluid) near 100% of the energy used. This is because near 100% of the energy used by processors is converted to heat. There is no way for the heat to get 'outdoors' if it is surrounded by a fluid. All the heat must pass to the fluid before it goes anywhere else.
And it is also worth noting that 'losses' in a carnot engine are almost purely heat. When you are trying to heat something you get to keep all your heat, it is not lost. Say you have 10kW of waste heat, and your heat pump is 1kW. You will put out 11kW of heat. If your heat pump is 10kW you will put out 20kW (10 + 10) of heat. Both ways you still recover the entire 10kW, and if you need more heat anyway then the effiecency is a moot point (in reality it is relevent because it is cheaper to heat water with natural gas, than electricity).
You are looking at all of this to complexly. Carnot cycles are for calculating heat engines. This is not a heat engine. There is NO WORK being done.
I put electricity into a chip. The chip uses X amount of energy and ~100% of the (electrical) energy is converted to heat energy.
If I run water over the chips (lets assume fully submerged for simplicity) and maintain their temperature at 20 degC. ~100% of the heat is removed by the water.
I realize there are line losses in the electrical wires. There are heat losses from the pipes piping away the heat. There are also radiation losses in the form of light and other waves that transmit through the water.
But anyway a heat exchanger (properly and sufficiently sized) should be near 100% (~97%-98%) efficient.
Now when you use a heat pump cycle you start loosing efficiency, but it is again almost 100% loss of heat, which goes to the hot water loop.
I would imagine that such a system is ~90%+ efficient from electrical energy (going to all items being recovered) and the heat pump cycle.
You need to ask yourself how and where does the energy go if it doesn't end up in the hot water loop?
What is the big advatage to a "multi touch" mouse. What does it offer that my Microsoft mouse doesn't do?
Click. Both (but i leave my fingers on the surface of the mouse, will the Apple one require me to lift my right finger?)
Right Click. Both. (same issue as above)
Scroll up. Both (I have a nice wheel, it has acceleration and no indentations)
Scroll sidways. Both (my wheel tilts sideways, never really needs use)
Go back. Both (I assume there is some two touch swipe method for this, I have a back button)
Zoom. Both? (pinching would require some weird scissor motion or repositioning your fingers, my mouse has a button)
Middle click. MINE. (sure the apple mouse will probably get this but it only does 2 inputs now).
Sure this sounds good and all but my mouse already does all of these things REALLY well.
Yes ATT has never and will never call EDGE 3G. The 3G specification which was put out by International Telecommunication Union has EDGE in the specification.
3G CAN include EDGE, because well it is in the DEFINITION FOR 3G. Not because someone says it is.
ATT 3G != Verizon 3G. So showing the maps shows 2 different things. If they are showing different then why shouldn't EDGE be on the ATT map? Sure ATT doesn't advertize it as 3G. But it IS 3G.
And I know it is WAY slower than Verizon '3G' and ATT '3G'. But the map in the ads is wrong. EDGE IS 3G by the onyl real standard there is.
Well not so much games. 3G was never supposed to indicate speed.
0G - Radio phones (walkie talkies, CB, and the like)
1G - Analog cellular phones
2G - Digital cellular phones (where data was added onto the 'talk' stream)
3G - Digital cellular phones with data desigend to be accomodated
Sprint, Verizon have ~1.4 Mbps system, and have the best coverage
ATT has ~3.5 Mbps "3G" And have OK coverage
T-Moblie has not specified their speed but probably have 7.2 Mbps, but have limited urban area coverage
And EDGE which ATT considers 2.5G is actually in the 3G specification. They advertize this so people don't expect 'fast' data access with 2G, and to get people to upgrade to 3G.

Try a top tier Engineering Undergraduate program. I bet it is worse than most of the professional programs out there.

ID4 is proof (and should be a lesson to everybody) that security through obscurity is not.
Yeah but there is a middle ground between Atom and the fastest Core2 you can put into a 'laptop'. You can get low power fast processors and get 4-5 hours of battery easily.
Look at the X200S by lenovo.
I agree 100%. Atom processors are a combination of stuff that I don't want. Too slow to do anything. So who cares about battery life.
Except the Everglades, Big Cypruss, Timucuan, and Biscayne are FEDERAL LAND. The FEDERAL GOVERNMENT should pay for it.

+1 informative. MSFT is still hugely massively, obscenely profitable.

Exactly, I have shit quality over VOIP all the time. Not to mention the problems with E911, location.
You expect anyone to believe that running SETI@home consumed more than 2.6 times the electricty as the rest of your house?
25 * 2.6 = 65 + 25 = 90

Oh and printing, or pencil and paper copying, is the only way to use a recipe.

Yeah but all the efficiency/carnot losses end up in the hot water.
Well it can be fairly efficient. http://en.wikipedia.org/wiki/Floor_heating#Efficiency
The main benifit is that you can easily recover waste heat. From power plants, or any other large heat source.
And with proper insulation you can limit your heat losses.
How is the Carnot cycle apply here? This is direct heat conversion, and the efficiency should be near 100%, you would have line losses.
I too had Red Screens of death on my 2k and, XP boxes while attending Georgia Tech.
2^5 = 32
Still not that many though.
