Get yourself a good chemistry/physics reference book and look up the isotopes of plutonium and the other radioactive elements. If it's "hot", it has a relative short half-life. Contrary to popular belief and anti-nuke propaganda, plutonium is not the most toxic substance on Earth. It's nasty stuff, but so are many other elements and compounds. If you want something that will give you nightmares, check out dimethylmercury. It makes plutonium look like health food.
You can't just wave a magic wand and double the density. Many of these things are interrelated in a complex manner. Increased density requires new head designs, new and improved electronics, new coatings for the platters, etc.
No. Track densities are far too high for that to work. Each active head needs an independent servo channel and positioner. On a standard drive, only one head is active at a time.
With modern drives, you have to discard the model of the drive as a perfectly rigid and dimensionally stable mechanical device. Keeping a head positioned over a track is like driving a car at very high speed down a road that is constantly and unpredictably curving in one direction or another.
CDC's hard drive division did this years ago. They were later acquired by Seagate. The drives were too expensive for the improvements in performance and were discontinued. It isn't only a set of heads, it's another positioner assembly and a large amount of duplicated electronics. That's more power, heat, PCB space.
I recently bought a Tivo, the cheap one, and was surprised to discover that the serial interface on the Motorola cable box actually worked. Usually all of the optional features are missing or crippled.
The reality is that devices with cable card support, other than the Tivo HD, are almost impossible to find, and getting the cable company to install and properly configure cable cards is often an extended trip into customer service Hell.
There are technical reasons for the cable company to use different frequencies than those used for OTA broadcast. It allows the full use of the bandwidth provided by the distribution system. It also avoids the interference problems that happen when a broadcast station and a cable system use the same frequency.
Huge? Most of the people that I know own a cell phone, and none of them own an iPhone. In fact, the only iPhones that I've seen have been in ads. Apple may have sold millions of iPhones, but they still have just a tiny slice of the global cell phone market.
The Brits are more than capable of bombing their own troops. Friendly fire is not a uniquely American problem, so don't fool yourself into thinking that your shit doesn't stink.
Someone once told me that the military used a similar trick in the cameras used for low-level, high-speed reconnaissance in Vietnam. The pilot would overfly his target at tree-top level, to avoid enemy anti-aircraft fire. The camera had to compensate for the apparent motion of the target.
We know illegal felonious comments (threats of rape and murder) were allowed to remain posted on the website.
We know? No, we don't know, you fucking idiot.
Libel is almost always a civil matter, not criminal. There is no indication that anyone has been charged with any criminal offense.
It's doubtful that any of the reported remarks would qualify as misdemeanor (second degree) threats under Connecticut law, let alone felony (first degree) threats.
When the company has essentially gone "paperless", email gets used for everything. That includes work directives, requirements documents, policy statements, HR information. and almost everything that used to require a paper form. If you think I'm going to sacrifice myself on the altar of blind obedience to authority, you are naive.
I used to work for a company that decided to delete all email after 30 days. While I'm sure it made the lawyers happy, it made life difficult for anyone who was trying to actually do work. Email archives are important as a record of decisions, requirements, purchases, agreements with customers, and company policy directives. Sometimes people and corporations conveniently "forget" what they said months, or years, ago. If I can't keep it in my mailbox, I'm going to print it out and store it in a safe location.
Some of the recent STBs actually do a decent job of dealing with multipath. Even in infamous locations like Manhattan. Compensating for multipath has been an active area of research and development. A sophisticated equalizer can compensate for the effects of multipath.
I have a $60 STB that performs much better than earlier generation boxes that were much more expensive. The only problem is that it down-converts everything to SD.
It's a lot cheaper to relay network HD feeds and do everything else in 480i than to upgrade all of the equipment and sets to HD. Even the makeup needs an upgrade for HD. For a station that was already behind the curve, it's a huge expense to bring everything up to date.
The FCC did not have a crystal ball that would allow them to see into the future. The original proposals for HDTV were analog systems. There was no workable proposal for an all-digital system until about a decade after the formation of the ATSC. It took additional years to turn it into what we know know as ATSC. This was all bleeding-edge technology, right out of various research labs. MPEG-4 wouldn't be finalized until more than a decade after the FCC selected ATSC as the standard for HDTV in the USA. The FCC went with the best technology that was available at that time. Standards always become obsolete over time, but they are necessary. It's only recently that ATSC receivers have matured to the point that they have reasonable performance with impaired signals and prices that are acceptable to a mass market.
An MRI works on different principles. An EM field is produced by EM radiation. Look up the "dipole moment of the water molecule". The oscillating EM field inside the microwave oven transfers energy to any molecule with a dipole moment that is free to move.
Microwave ovens operate at 2.45 GHz because that frequency resonates with water molecules.
No, they don't. That's a common misconception. Water molecules behave like tiny magnets. The EM field of the microwave oven makes them flip back and forth, which produces heat.
Has mercury replaced plutonium as the most feared element by the "Let's all run around in circles, and scream and shout" wing of the environmental movement?

I could probably afford the camera and film. The tricky part would be getting the RF-4 recon aircraft. Thanks for the pointer to Surplus Shed.
The failure in Vietnam was political, not military.
