Cell Phones In The Air?

It's called sidetone. A small percentage of the audio from the microphone is diverted to the speaker in the handset. It's a standard feature of landline telephones.
It would be trivial to modify the battery pack to contain a smaller battery and then fill the vacant space with explosive material. The phone would still work, just for a shorter time.
There is a great deal of anecdotal evidence for passenger electronics devices causing interference to aircraft systems in NASA's Aviation Safety Reporting System database. Some people may argue that anecdotal data isn't proof, but I've read enough of the relevant reports to convince me that it is a real problem.
It's amazing how many idiots refuse to comply with the instructions of the flight crew, even after the captain has made an announcement reminding the passengers to shut off the offending devices. If it was up to me, I'd have the flight crew seize the passenger's carry-on items, and have the passenger arrested and charged for disobeying the instructions of the flight crew and endangering the aircraft.
As I understand it, there are two sets of applicable rules, the FAA's and the FCC's. The FAA is primarily concerned about flight safety, preventing interference to the aircraft's communication, navigation and control systems. The FCC is primarily concerned about interference to land-based cellular systems. There are many FCC approved devices that can't be used on aircraft due to safety concerns. The FAA has its own system for testing and certifying equipment used on aircraft. Any system that allows the use of cellular phones on aircraft will have to be approved by the FAA, FCC and the operator of the aircraft.
A DC power supply isn't as useful as you might think. Many devices, like your computer, would have to convert it to AC, so that it could be converted to regulated DC at the proper voltages. As a means of transporting raw electrical energy, AC is hard to beat.
Your P4 is going to wear out, if you run it long enough. Look up electromigration. The trick is to design the chip so that it will last long enough that it isn't a practical issue.
Teenagers do not have fundamental privacy rights, at least as far as their parents are concerned. The case that you cited is an exception in the law, not the general rule. Short of abuse, parents have wide-ranging power over their children.
You can get the password file if you can trick a system process running as root to read it and send it to you. This has been a common security exploit for many years.
Large cities have a noticeable effect on local climates. I don't know how much of it is due to the wind braking effect of the buildings, as opposed to artificial sources of heat and changes in solar reflectivity.
Wind and hydro have their own environmental problems. Hydro, in particular, can have severe environmental consequences for regional ecosystems and human populations. Some of these effects may only become apparent after billions of dollars have been spent and many years have elapsed. The Aswan dam in Egypt is a good example of all the things that can go wrong when you try to control a river.
I've read a number of articles that state that Microsoft does not use Visual SourceSafe for internal development. They use home-grown software that has not been released to the outside world.
Most spell checkers are mediocre and I've never seen a grammar checker that was worth using.
Maybe Microsoft should spend some money on improving their spelling and grammar checking software. That would actually be a useful enhancement, and selling point, for their Office software.
What you are describing is a federal crime and would result in severe consequences for the contracting company and their management. Labor charges for federal contracts are audited on a regular basis.
Assuming a large enough FPGA, you could implement any processor out there (and throw an Ethernet controller, VGA controller, etc onto the same chip).
Assume a spherical cow...
While FPGAs are useful devices, they are slow, expensive, and inefficient when compared to custom logic. An FPGA large enough to implement a modern processor would be insanely huge.
When is the Indian government going to take responsibility for their own involvement and contributions to the disaster and its aftermath? We have the Indian subsidiary of a U.S. company, owned by Indians, managed by Indians, operated by Indians, regulated by Indian law, which is made and enforced by Indians.
Yet, the incident is portrayed as being solely the fault of an evil foreign corporation. How convenient. It's disingenuous for India to play the "we're poor victims of Western colonialism" card at this late date.
OpenBSD is based on an old architecture, design and code base, that while advanced for its time, is not suitable for a modern, secure operating system. It only looks good because most of its competition is so pathetic.
NSA's involvement in Linux amounts to a research project. Although I think it is interesting and useful, it shouldn't be mistaken for an endorsement by the NSA.
I can't think of a single desktop operating system available to the public that is truly security aware, from design to implementation. The architects of Windows NT started out taking it seriously, but security quickly lost all battles to the proponents of compatibility, performance and "more features". OpenBSD is an example of how auditing is necessary but not sufficient.
Often times it isn't worth the effort to compress data, especially when your network bandwidth greatly exceeds the rate at which your system can compress the data.
One of the RC servos could be setup to pull the pin on the grenade after it was moved next to the target. If you had more time and money, the grenade's fuse could be replaced with an electrically initiated detonator connected to a receiver and command decoder.
From past failures of geosynchronous communications satellites, there appear to be several classes of users. The people who pay the most, get guaranteed service and are quickly switched to a transponder on another satellite. The people who pay the least, lose their service and have to find another satellite, if any, that has unused capacity.
It's big enough that the Air Force can track it on radar and keep it in their catalog of orbiting space junk. If there is a danger of a collision, they can send a warning to the owner of the other satellite so they can take evasive action.
When something like this happens, they often see anomalous telemetry readings before the complete failure of the spacecraft. For example, main power bus current goes from 10A to 200A and main power bus voltage starts going down, down, down.
The engineering telemetry link on a geosynchronous spacecraft is usually monitored 24/7 by the spacecraft's control center.
In peacetime you can call the EOD detachment and wait for them to come and deal with the device. During a war, you may not have that luxury. You deal with the situation as best you can, given the available resources.
A control and telemetry RF link is unlikely to cause an accidental detonation if the power is kept reasonably low.
What I would like would be a disposable RC car and hand grenade that could be driven next to the device and detonated, to either disrupt the device or detonate it in place.

If you apply for a security clearance, you have to submit a set of fingerprints. Many federal jobs, civil service and contractor, require a clearance.

Regarding Windows NT, I meant Cutler et al.
