The reason people in Europe have lots of diesel and in the US they don't is funny US regulations. The US smog limits are per gallon of fuel and the European per mile driven. Diesel is much heavier than gas, so has more stuff in each gallon burned, but more energy too. If the US rules were per pound of fuel or per mile driven then Diesel would be popular like in Europe.
I am convinced that Vitamin D is important for resisting the flu. It is produced in your skin from sunlight. It is important for your immune system. During the winter most people don't get enough, which seems to be why the flu is more common then. Very young and very old people get even less sun than normal and are worse hit by the flu. The same flu virus is not nearly as deadly during the summer. The recommended daily allowance of Vitamin D was calculated to be enough keep people from getting rickets but is far below what your body will produce given 15 minute of sun.

I want my next computer to have no disk drives and no fans, because my last computer like that is still working 25+ years later. Most of my machines did not last 1/5th as long. Nice little machine my Atari-400.
A UPS tries to run on wallpower if it can, but uses battery if there is no wallpower. I want an inverter that is sort of a reverse UPS. I want it to run on battery if the voltage is good but switch to wallpower if needed.
This way I can use solar power if I have any but my stuff (window AC, microwave, whatever) will still work when the batteries are too low. It has to be a bit smart not to switch back till the voltage gets above some threshold.
Is there such an inverter? What is this type called?
A computer programmer is used to simulating a computer executing his code in his head. He thinks, if I change this then its going to do this. So when it comes to government policy, he does the same thing. He can't help but see the impact of price controls, wage controls, not letting companies fire employees, etc. If you can really think through to the results of many government policy ideas, you realize that Libertarianism makes the most sense.
Also, I converted to Objectivism when I was 12 years old, before I had money.

That MIPS is not dead is both true, and a good point. However, the Zilog Z80 is not dead either. But we don't get very excited about it any more. When we got our first one, it was way cool, but today most people would not even think about the fact that
Zilog still sells Z80s.
The energy to lift the Moon's orbit comes from the rotational energy of the Earth, which is limited. As the Moon gets higher the Earth rotates slower. There may not be enough energy to lift the Moon high enough to qualifty.
At some point I think they will license "per die". The problem with per socket is then Intel and AMD can save their customers software license fees by packaging multiple die in a multi-chip-module. There is no clean cut-off once this starts. Licensing is already different for IBMs Power multi-chip-modules. Software companies would not maximize their profits if a $100 CPU license cost the same as a $40,000 multi-chip-module because they both used one socket. Anyway, in the future it will be "per die". You heard it here first.
"...the universe is instead about 15.8 billion years old and about 180 billion light-years wide."
So the radius is 90 billion light-years and average expansion speed is 90/15.8 or 5.7 times the speed of light.
So most of the matter in the universe is proving that it is possible to go faster than the speed of light. With such a big proof it is amazing people don't notice it.
I am now liking the
Hurricane LX800. This has a fanless
Geode LX, which I think
has the nx-bit. It has 2 ethernet and 4 USB-2 ports,
onboard video, and much more. It uses only 5.3 watts.
Works up to 85 C (that is really hot!). Rated with a
100,000 hours MTBF. With no disk, and 2 USB flash sticks in a
RAID/mirror, I should not have hardware failures very often. And it seems
the price is under $400.

What I really want is a fanless/diskless/ventless system that has a CPU that supports the nx-bit. I think such a computer should last a very long time without any trouble. I think any server of any type on the Internet should have the nx-bit support. But finding this in a diskless/fanless/ventless computer has not been easy for me. I am not able to drop into Fry's etc though. Does anyone know of such a system?
I was told there was going to be a version of the
PIC that would be willing to boot Linux. This would be perfect. But after 1.5 years of waiting, I don't want to wait any longer.
[...]you might be better off with an embedded linux SBC [...]
I would be happy with any fanless/diskless computer without vents. I have had about a dozen computers for about a dozen years and my failures have been due to disks breaking, fans breaking, and bugs getting into the computer and pooping (I live on a tropical island).
The
PIC would be great if I could boot Linux from a USB port.
Now, that said, why are you trying to keep your server up and running for a long time? Presumably, the client machiens are also down during these outages?
The clients are all over the Internet. With independent failure modes, I do not presume they are also down.:-)
My Internet link keeps working when the power goes out. It is just like the phones keep working when the power goes out, because it is also the phone company. My router is a linux box. Yes, I need a UPS for the hub and the DSL link, but they don't take much.
>The best advice I can give is - try to make it not use any moving parts in normal operations.
I think this is very good advice. USB Flash does seem like the way to go. Do you need to do something so that logging does not wear out your flash though? (ramdrive?) I guess I can even software RAID a couple USB flash sticks too. I like the idea of having a backup USB for each system and a spare system that can be turned into whichever machine I need in an instant.
Looking and thinking some more, going with a mini-itx system that is fanless/diskless
could be the way to go. They seem to have even lower power CPUs than notebooks. And the notebooks that I have bought do have fans, though they are usually off. But I want servers to have nx-bit support, and I am not sure that the mini-itx fanless systems do.
Processor
Dual-core 64-bit processing power means smooth performance and complete control of your digital media.
Intel
launched VIIV at CES
with the "Centrino Duo" platform
that uses their "Core Duo" processor (also known as Yohan).
But as with all Intel notebook chips,
Yohan is 32-bit only (look for "1" footnotes).
So the VIIV that is really shipping is 32-bits.
And the correct way to write 32 in roman numerals is XXXII.
>I think we can all agree that the Pentium-M is superior for laptops,
No. AMD's chips can also run 64-bit code, while Pentium-M is 32-bit only. Since people hate buying machines that become obsolete soon, 64-bit should be viewed as superior.

Google has said they are working on software to compete with Microsoft. Think Sun was in on this too.
