I have been astounded but not amazed at the deeply adolescent and peevish libertarian attitudes that so many techies cling to, from gun worship to fear of governmental Internet regulation.
I suppose Thomas Jefferson was an "adolescent and peevish libertarian"? Some of us are deeply concerned about our freedoms and liberties, which are too often sacrificed on the altar of convenience and expedience. I believe in the principles that underlie the Constitution and Bill of Rights. Freedom has a price, which many Americans are unwilling to pay, preferring the security and conformity of the nanny state.
The Poles obtained a commercial Enigma and were the able to analyze and crack the military Enigma in 1933. While the British did a lot of important work on the Enigma, the Poles, esp. Marian Rejewski, deserve most of the credit for cracking the Enigma. Too many books and articles ignore their work.

As for the soldier, well he really is just a link in the chain, since that's the way the military works. He just follows orders, he doesn't need to worry about them. He can't decide which are the "real" orders and to which ones he should say "That's immoral/unethical, I'm not going to do that". And yes, this IS straight out of "A Few Good Men".
A soldier has a duty to disobey an illegal order. That is the policy of the U.S. Army and it is International Law. That is what I was taught when I was a soldier. You can be court-martialed and convicted for carrying out an illegal order.
I'm interested in microkernels for high reliability systems. One of the problems with most operating systems is that a device driver or major subsystem, such as networking or graphics, can crash the kernel. What if each device driver and major subsystem ran in its own address space? The address space would be restricted to the module's code, data and the address space associated with the I/O device. If the module crashed, the microkernel could recover by reloading and restarting the module.
The problem is that you need a power source, transmitter and antenna to transmit the results back to Earth. They are going to have to be much heavier than a gram to get a high enough ERP and a reasonable data rate.
I believe they detect planets by looking for doppler shifts in the light emitted by the star. The planet causes the star to wobble in a periodic manner.
Global warming has been used as a political issue by both the left and right to further their agendas. Al "don't confuse me with the facts" Gore has hopped on this as "his" issue. This has corrupted science. Researchers who discover or publicize "politically incorrect" results are likely to have problems with funding.
Your stereo is broken, like most consumer electronics equipment. Shielding and filtering costs money, which most manufacturers prefer to keep for themselves. You should be complaining to the company that made your stereo.
The typical problem is that long, unshielded speaker wires behave like an antenna, feeding the RF into the power amplifier. The RF get rectified/detected into audio and amplified by the power amplifier in the stereo. Your stereo has become a radio receiver.
You probably should use copper instead of aluminum. It is difficult to make good electrical connections with aluminum. With copper, you can solder the seams between the sheets of material.
Why does anyone vote for Feinstein? It seems like every time I read about some whacko bill to gut civil liberties, her name is on it. This is the same woman who had the only concealed carry permit in San Francisco, while she was busy trying to disarm honest citizens.
They already have jurisdiction over e-mail chain letters that ask the recipient to mail cash to the sender. You can send copies of e-mail chain letters to the regional postal inspection service office. I used to do this with all of the MMF spam.
That is the reason some con artists ask their victims to send their cash or check via Federal Express instead of the USPS.
One of the common lines was "We charge for a letter across town and across the country. A great deal!" But did anyone think about that? Isn't the schmuck sending a letter across town getting screwed then?
Some people pay more than the cost of delivery and some pay less. The primary goal of the post office is not economic efficiency, it is the welfare of the United States. That means a reliable, affordable and universal system of communication, whether you live in downtown Boston or on a ranch in Montana.
Katz's proto-ideas about some sort of slush fund for artists doesn't take into account an artist's individuality: I don't want a predetermined fraction of all the profits, I want my profits from my songs.
Fine. Then you can also do without the coercive power of the state, as expressed in copyright laws, a court system that enforces those laws, the people who investigate and prosecute copyright infringement, prisons and parole officers for those convicted of criminal copyright infringement.
Copyright is a social contract. It does not grant you absolute rights to "intellectual property". The fact that you created a song does not give you absolute control over what other people do with "your song".
The problem with the optical track ball is that crud collects on the tiny ball bearings inside the housing. This prevents the ball from rotating smoothly.
The original copyright laws, such as the Statute of Anne in England, were more about protecting publishers and the state than they were about protecting authors. If a publisher had purchased a manuscript, and had it set in type and printed, he didn't want the market for the book to be damaged by another publisher reprinting the book. A publisher had the exclusive right to publish a given title, even Greek and Roman classics that would be in the public domain under current law. The crown wanted control over the publishing industry, to prevent the publication of subversive or heretical literature. The publishers wanted to suppress competition and make money. Rhetoric about the "rights of the author" was used to justify a system that enriched publishers much more than authors. When an author sold a manuscript, the "rights of the author" were transferred to the publisher.
Hey! How can artists protect themselves? By reading the bloody contracts presented to them by the recording industry.
You would have a stronger argument if the recording industry was a free market. The major labels control distribution and promotion. It's their way or the highway.
The situation reminds me of professional baseball in the "good old days". If you wanted to be a professional baseball player, you signed your soul over to one of a limited number of teams, who were owned and controlled by an old boys club. Players were "owned" by the teams. If you didn't like the contract and you were not a major star, too bad. Players were treated like property, to be bought and sold at the convenience of the owners.
Pu-238 is produced by irradiating Np-237 and chemically extracting the Pu-238. I don't know what the process is for creating the Np-237. The problem with spent commercial reactor fuel is separating the desired material from all of the other elements and isotopes. Special "low burn-up" reactors are used to produce Pu-239 from uranium. A commercial reactor produces plutonium with a high percentage of short-lived plutonium isotopes, which is undesirable for use in nuclear weapons. Chemical separation extracts all of the plutonium, not just the desired isotope. For RTGs, you only want the Pu-238.
There are three ways to dissipate heat, radiation, conduction and convection. In a vacuum, your choice is limited to radiation. You radiate the excess heat into space. There is some tricky engineering involved in keeping the different parts of a spacecraft within a reasonable temperature range.
This isn't Pu-239, the isotope that is used in nuclear weapons. We have huge amounts of Pu-239. Radioisotope Thermoelectric Generators (RTG) use Pu-238, a plutonium isotope with a much shorter half-life (87.7 years). The problem is producing the material. Pu-238 was produced by the Department of Energy as a byproduct of the nuclear weapons materials production infrastructure, which has largely been shut down. There has been discussion of restarting a capability to produce Pu-238, but I'm not sure if any progress has been made. There are plenty of anti-nuclear know-nothings who are opposed to the idea.

Why don't we give it a try? :-)

I've often wondered what would happen if you fabbed an old design like the 6502 on a modern process, a 1 GHz 6502?

What's that word in between "debated" and "rights"?

There are many people who are opposed to abortion who are not bible thumping fundamentalists, or even Christians.
