Comment: does not matter (Score 0) 159

The amount of released CO2 simply does not matter because when the plant regrows it will absorb exactly the same amount again.

The only question is the total amount of CO2 in the biosphere, not the output of single reactions inside the biosphere. Reducing the total amount can be either done by "growing" more CO2 containers or store CO2 by industrial methods eg underground. The later sounds strange but works pretty well, a single plant with a 10MW power source can easily outperform a 100km forest in CO2 reduction.

Actually x86 IS efficient for for something completely different. The architecture itself is totally unimportant as deep inside it is yet another micro code translator and doesn't differ significantly from PPC or Sparc nowadays.

x86 short instructions allow for highly efficient memory usage and for a much, much, much higher Ops per Cycle. This is just that big of a deal that ARM has created a short command version of ARM opcodes just to close in. But then this instruction set is totally incompatible and also totally ignored.

Short instructions do not matter on slow architectures like todays ARM world. These just want to safe power and therefore it fits in well that ARM also is a heavy user of slow in-order-execution.

A nice example, increasing a 64 bit register in x86 takes ONE byte and recent x86 CPUs can run this operation on different register up to 100 times PER CYCLE, all commands to be loaded in THREE to EIGHT Cycles from memory to cache. On the other hand, the same operation on ARM takes 12 bytes for a single increment operation, to load some dozend of these operations would take THOUSANDS of clock cycles.

And now you know why high end x86 is 20-50 times faster than ARM.

As far as I remember in the whole history of civil nuclear power there were roughly 687 fatalities recorded by civil nuclear power, even if one includes cases of long term neglected diseases.

On the other hand, in the same time around 2.500.000 people died of hydropower with 250.000 alone in one major dam bust 40 years ago in china.

As nuclear power produced roughly 10 times as much energy in the same time based on "deaths per watt" hydropower is 35.000 times more lethal than nuclear power.

Tell this to the believers of the anti nuclear church and they will nail you to a cross... always look on the bright side of life...

the whole article is stupid to the bone.

1. todays active defense systems are already capable of only engaging objects on a dangerous course and ignoring all others.

2. spamming thousands of missiles over days wouldn't go unnoticed by the target of the attack. in other words, the attacker will get taken out before he has done any relevant damage.

3. there is no nation on earth able to spam thousands of missiles for extended periods.

Now lets discuss how many cute kittens one must throw against an AEGIS cruiser to overwhelm its defences.

an eigth years old washing mashine?

thats nothing. my mom got rid of her 50 years old Siemens washing machine. It wasn't broken, it just had a leaky pipe and was dump like bread.

Ok, it had its "flaws", e.g. it took 30-60 litres of water for washing. BUT the water could be reused or be taken from rain or other third grade water supplies. In fact if done right you could use the same 30 litres of rain water to wash 20 loads of clothes.

There are even more problems, for example the whole hardware is only remotely related to common ARM plattforms. This goes as far as you are not allowed to use the cheap USB/HDMI/SATA/PCIE devices used in other systems because these are easier to hack.

Nice side effect: surface systems are inherently expensive because they are so uber special.

Seriously, microsoft must have been living under a rock. Windows has always sold because it was quite open in comparison with the competitors, not because it was totally isolated from the user.

Don't take my writing too serious but what hardware is Steam4Linux supposed to run on?

My P3-Dualcore@1,33Ghz doesn't offer PAE so Ubuntu doesn't run.

My P4@3,2Ghz offers PAE but its Geforce 6800 - although technically within specs - fails starting TF2 because of some GL-extension missing. As the 6800 is the best native AGP solution available this is a dead end. At least it runs Penumbra although every level change will reduce FPS by 90%.

My Core-Q9550@3,4Ghz with its Geforce 260 is technically speaking just fine but officially I may only use Ubuntu 32bit and waste half of my memory (yeah, easy to work around) but still I need the uttmost updated bleeding edge drivers just to move the steam window around. Ayeah, 3D-unity and Steam hate each other. And every 3D game hates 3D-unity and Steam at once. So better disable 3D unity and close steam before launching the game or you will have 5fps.

My i7-3770K and also its Geforce 670 are too new for Unity. Couldn't get both running useful.

The only system running out of the box (mostly - WLAN runs better with hand compiled driver) is my netbook EEE 901 from 2008. Oh but I might mention that Steam needs between 10 and 25% of CPU even with all windows closed and doing nothing at all. So better learn to use cpulimit or your battery will be empty in no time.

Still its an interesting experience.

Nobody said computers were going to be polite.
