Well the Xeon i7s aren't too much more expensive and they support ECC. If ECC is that important you could spend the $20 or so more to get the W3520 instead of the 920.
How much do the Xeon i7 motherboards cost though? Most of the consumer i7 motherboards and all of the early ones are significantly more expensive than the ECC supporting AM2+ motherboards.
I build a Phenom II 940 system for this very reason. The money I saved on the motherboard, processor, and RAM while still having ECC payed for a fast hardware RAID controller.
My ISP still provides NNTP by contracting through Giganews I believe but if it were dropped, my NNTP traffic would just end up going right out their peering and transit links with much less control for them. If they want to play that game, I am all in.
So proxy port 119 for your user's NNTP access and cache articles that are actually requested. You will not be able to exchange news in the same way major providers do but whoever you buy your NNTP service from will be able to. Many ISPs already do something similar to this (I do not know that they actually bother with the proxy) by buying NNTP access for their users from one of the major third party news providers so they do not have to maintain their own local servers.
As someone else posted, a significant fraction of the NNTP traffic ISPs save by not hosting local NNTP can or will be replaced by torrent and external NNTP traffic which can have a greater impact on the ISPs links to the greater internet. I know in my case that if my ISP dropped local NNTP which I believe goes to Giganews, I would redirect it all onto protocol 41 supported IPv6 and right out through their peering and transit links.
if the Fithp had gone behind another leader then the whole thing might have gone very differently.
How many encounters between colonial powers and natives were ultimately peaceful? Even without violent conflict, native cultures are assimilated in one way or another with some minor exceptions. Even if they are just missionaries, that may or may not be good for the natives.
In the case of Footfall, the Fithp intended to conquer earth, Winterhome to them, from the start. Dawson's discussion with the Heardmaster's Adviser (who is the deposed original planet born Heardmaster) goes bad when he reveals too much to the fi about human culture, science, and technology. The Heardmaster would conquer earth for a place to live and the Heardmaster's Adviser would conquer the humans to integrate their future progress into the heard for which Dawson kills or thinks he kills him.
In the end of course things do go differently as the Filph get a new leader in a roundabout way.
I have often wondered about this since I read Ringworld Engineers and Protector. Was Niven unaware at the time of writing how impossible it would be for Pak descended Homo Habilis to fit into earth's fossil record and evolutionary biology or did he just hand wave it as a minor contradiction with known science? He had common biology spread across Known Space because of the Slaver Empire but the hominid to Pak connection always bothered me.
. . . that is to say, descended from the Pak (aka Homo erectus).
Pak were Homo Habilis in Niven's stories or at least that is what the various characters speculated. Only the UN/ARM and Brennan-monster had access to fossils from earth for an investigation that I remember.
Kinetic energy weapons do not scale down but cutting and drilling weapons do. Equip the bird with a drill lance and a chain saw.
Of course, that works in the opposite direction also. If the bird is small enough, throwing it will not damage it but spraying it with honey or glue would be incapacitating.
Genuine question: Could you give me the reference to CFL being capacitive load? I tried to search around, but results seem to be mixed. Thanks.
They are not capacitive loads. They have poor power factor because of harmonics generated by the capacitor filtered rectifier and not because of phase shift. Some newer CFLs (the ones that support phase control dimming?) use active power factor correction.
I liked Enterprise for that very reason though. During battle, why wouldn't you use the transporter to either remove pieces of an enemy ship, board her with marines, or send over a surprise in the form of a nuclear or photon weapon? Diplomacy has its place but even if the Federation had good reasons to forgo certain military tactics (such reasons never having been given so far as I know), non-Federation races could use still them.
I still hope any further movies will either have actual warlike Klingons or even better, Kzinti. But I expect that last is too much to hope for.

the GPS signals are transmitted at 1.1 -1.5GHz so I assume the signals will also bounce off the ground
They certainly do, and off buildings -- multipath is a big issue for GPS in built-up areas. Your thinking is that the signal will work off ground scatter? Well, it would drop the accuracy, but it would probably still be good enough for tracking, so that might work.
I estimate that the reflection off of pavement would lose about 20db so I doubt it would work. It would be easy enough to test this though. Reflections from building are an issue because some modern building materials make adequate smooth RF reflectors.
Better would be to plan on an intermittent direct view of part of the horizon in one direction or cell phone tower based localization. A very low profile remote patch antenna would be clever if you could camouflage it though. How thin can a 1.5GHz patch antenna be?
All of the cars I have worked on (GMC, Ford, Toyota) use two separate hydraulic circuits for the front and the rear brakes and have a separate parking/emergency brake which uses a cable linkage to the rear drum brakes. I'm not sure how that last is handled if you have rear disc brakes.
Most hard drive cases are composed aluminum and stainless steel. Neither of these will provide significant shielding against a magnetic field used for degaussing.
Steel, iron, and mu-metal are commonly used for magnetic shielding.
The useful bug I remember from Sim City had to do with traffic congestion. If you built roads without any intersections, the algorithm which generated random routes from building to building would be limited to adjacent building so the roads would never be congested. At the same time, every building had road access to everybody was happy.
I think I discovered this when people where fleeing my housing developments for other reasons (creating slums), and I bulldozed the roads so they could not get away. It did not work of course but my heart was in the right place.
I have often wondered if a more orthogonal superset of the existing instruction set with a clean instruction encoding would be better. The JIT compiler would be dead simple since it would only have to translate. AMD apparently had that option when they designed x86-64 but decided full compatibility was more important.
All of the recent Asus AM2+ motherboards support ECC and the Gigabyte AM2+ motherboard without embedded graphics do as well.
I built an Asus M3A78-T ECC system recently and the money I saved over an Intel ECC system was more than enough for a good Areca RAID card which also happens to have ECC memory.
Impact energy is roughly proportional to the diameter cubed (volume or mass). All of those tiny asteroids that hit every day just do not add up to all that much. The damage to the earth's biosphere will be roughly proportional to the energy transferred which actually makes a water impact worse than a land impact unless you happen to be under it. For civilization, either can be catastrophic just because of weather effects. An impact like the one in Arizona is small on this scale although no doubt bad for the locals.
As someone once pointed out (Dan Alderson?), when dealing with an incoming asteroid above a certain size, it ceases to matter whether the earth has an atmosphere or not, except to us. It just will not be spending much time there.
That would be "big fat juicy ARMORED target". A 12 inch armor belt protects the machinery spaces and the barbettes are 12 to 17 inches thick so gaining a hard kill would be rather unlikely. On top of that, each turret has its own fire control systems independent of the directors. Even the decks have 7.5 inches of armor.
In theory a BIOS can purposefully refuse to POST if it detects (via the SPD EEPROM) that the type of RAM is ECC, but I have never seen any BIOS do that. What exactly did you notice with Gigabyte motherboards ?
I have not actually seen a BIOS reject ECC RAM when it could otherwise be used but some vendors are understandably picky for reliability reasons.
I have not tested any of the Gigabyte AM2+ motherboards but at least according to their documentation and other sources, they do not support ECC if they have on-board graphics which applies to the 780G and 790GX based motherboards. Their 770, 790X, and 790FX boards do support ECC but the later two come at a price premium compared to the 780G and 790GX versions. All of the equivalent Asus boards support ECC with or without embedded graphics so I bought one of those instead (M3A78-T) for my latest system as I had no need for the extra PCIe slots and so far it works like a charm. As I said in another post, the difference in money I spent compared to an equivalent Intel system bought a hardware RAID controller.
Someone can correct me if I am wrong but I believe ECC support requires SMM (System Management Mode) firmware support from the BIOS. You could enable ECC later in the boot process but I suspect intercepting and handling an ECC generated machine check exception would be problematical.
I just went this route with a Phenom II. The money I saved over an equivalent (and older technology) X38 Intel system paid for a fast hardware RAID controller.

Couldn't the image sampling be done synchronously with the heart beat for instance or is the integration time too long?

Damnit.
Those were my lines.
Protocol 41 FTW!
I am not really surprised either.

Although not widely advertised, RPN calculators largely ameliorate any problems with borrowing:
Borrower: "May I borrow your calculator for a second?"

Borrower: "Um, no thanks."
