One technique that I've seen used is to put the PCB for the computer inside a box lined with foam insulation. This also works with hard drives. The electronics produce enough heat to keep the interior of the box at a reasonable temperature.
The hard part would be coming up with a thermal control system that worked at both extremes, a hot summer day and the dead of winter.
I'd like to see these systems more widely installed. Lightning related deaths and injuries are surprisingly common at athletic fields. Unfortunately, it usually takes some dead bodies before a detection system is approved.
I've never understood this philosophy. Let's put lots of error checks and consistency checks into the system, then rip them all out when we ship the software or transfer it to operations.
If it doesn't have to be correct, we can make it run as fast as you like.
One of the advantages of the current system is that it limits the effects of election fraud. Even if there is widespread election fraud in New York, it isn't going to affect the electoral results in other states. In a national popular vote, every stuffed ballot box has the potential to change the result.
We don't want a pure democracy in Iraq. That would be a disaster. Ask the Kurds and the Sunnis if they want everything decided by majority vote. If the political system doesn't take everyone's interests into account, it will prepare the ground for civil war.
I can see an application for this sort of chip, adding intelligent I/O processors to the system, like the channel controllers on mainframes. Much of the I/O on modern computers is done at an embarrassingly low level.
This class of bug, and some others, can be prevented if the free routine checks the to-be-freed memory chunk for validity. I've done this in some embedded systems by setting a hidden magic number in each memory chunk that is allocated. The free routine checks for the magic number before it touches it. If the magic number isn't there, it generates an alarm message and returns an error code to the caller. Unique magic numbers can be used for each class of buffer, and to indicate whether the buffer is free or in-use.
I read somewhere (sorry, no citation) that the USA pressured South Korea to abandon a nuclear weapons research and development program back in the 1970s.
If North Korea did test a nuclear device, it could encourage South Korea and Japan to develop and build nuclear weapons. Japan could "go nuclear" very quickly. They already have large amounts of plutonium.
That's assuming the carrier's network supports AGPS and that the public safety agency is setup to use it.
In many places, state and local governments have stolen the revenue from the 911 fees on your phone bills and spent them on other projects. Never leave a pot of money in the same room as a politician. It is going to take years, and a major expenditure of funds, before all of this stuff is installed and working. That's not even considering the dysfunctional local politics that have blocked any progress in some areas.
Try telling the operator your location when you are on business travel to some generic office park in an unfamiliar city. Yeah, I'm somewhere in San Diego.
Add to this, PBX systems with secret procedures for getting an outside line, and spiffy telephones with 50 buttons, labeled in Klingon. Then there are places where a 911 call results in the ambulance being dispatched to the location of the PBX, which may be miles away from where the call was made. People have died because of crap like that.
That's not true for many of the new GPS receiver designs being developed for E911 use with cell phones. An example.
That's a 20-30 dB improvement in sensitivity when compared to a typical handheld GPS receiver.
IANAL but a company isn't free to put anything that it wants in a contract and have it enforced by the courts. A judge can invalidate all or parts of a contract that are illegal, unconscionable or against public policy.
Many SCSI drives used to be ST-506 or ESDI drives with an attached SCSI bridge board. As SCSI matured, drives were designed with native SCSI interfaces.
The same thing could happen with USB or FireWire. The drive manufacturer just needs to design some new silicon.
The systems are more streamlined in the sense that the party that gets elected will carry through it's agenda and not get stalled/sideswiped by others.
That is what scares me about parliamentary systems like the UK, where there has been a long-running battle to marginalize the House of Lords. What prevents the PM, assuming his party has a simple majority in the House of Commons, from acting like the supreme leader, enacting any law he pleases?
What are the checks on his power? Politics and efficiency are a dangerous combination.
Like many cable box features, that is an option. My cable box could have an s-video output and a serial I/O for remote control, but my cable operator was too cheap to include them on the boxes that they bought from Motorola.
If you don't understand the importance of the Constitution and why filibusters are such an integral aspect of the checks and balances, please don't post in this section.
Another example of the open-mindedness of so-called progressive political thought? Agree with us or shut-up! The other side is just a bunch of racist, fascist, homophobic, sexist, bible thumping, war mongers. No freedom of speech for them.
It sounds much more like a 1930s pulp fiction serial, which appear to be the inspiration for the film. They were the special effects films of their day, even if they look cheesy to modern eyes. Unfortunately, most young people have never seen these films.

Why didn't the Brits make their own version? Hammer made some great Sci-Fi movies, like Quatermass and the Pit.
The Orson Welles adaptation of H.G. Wells' work was a classic in its own right. I think both can coexist.
Only in debug mode, of course.

A huge amount of work was done on Solaris to make it run efficiently on multi-processor systems.

That doesn't work if they take your pair and give it to a paying customer. No wires, no 911 service.

Don't throw away your vote by voting Republican!

More often. Evil villains can't seem to hire their own scientists, so they are reduced to kidnapping them.

Hubble does a lot more than just imaging in visible light. How about spectroscopy?
