..and unfortunately, political processes do not follow rules or regular expressions. What you are now witnessing is akin to marketing, not engineering, in that everything has a purpose, but there's no way to precisely predict the outcome (at least not yet). For the Democrats, who now have no chance to maintain, the goal is to damage the Republicans as much as possible.

Without a doubt, L Band. Full of noise from ancient radiolocation systems, diathermy machines, inadequate spread spectrum systems, and crappy propagation to boot.
Corporations are tools, not necessarily evil in and of themselves. They do, however, often reflect the values of their founders. Take, for example, Larry Ellison and Oracle (sell your life to the company and we'll make you rich), or Ken Olsen and DEC (we'll help you develop you career and keep you around, even if it hurts).
To fail to understand the corporation and its workings is to guarantee that your technology will never succeed -- and I don't care how good it is. Worse, it can put you at the mercy of someone who doesn't share your values.
That depends on your definition of Work. You think that sitting around reading Slashdot is WORK? Try moonlighting as a railroad employee (brakeman or track worker) and see what real work is all about.
What Katz sees as evidence of Corporatism is nothing more than employee greed. In the get-rich-quick IPO mania of the 90s, people have been willing to sacrifice their lives for a shot at retiring early. Nobody forced you to go to that pre-IPO startup with gobs of options, and you knew full well that it was a craps shoot. Sometimes the gamble pays off, and you'll be able to spend the rest of your life with your family and hobbies.
But if you truly enjoy what you're doing, do you really care? Many of us were out to change the world and make it a better place, and no revolution was ever done 9 to 5.
Jose Bova's "plight" is little more than thinly-veiled xenophobia. The not-so suprising thing here is having John Katz rail against science in the name of luddites. The root question is whether or not well-proven technology should be applied to the growth and production of food, period. Katz is, once again, siding with the anti-science luddites, who somehow believe that all of the scientific studies done by the FDA and private companies of bovine growth hormone and food irradiation are corrupt, that there is no way a scientist or engineer working for a corporation could ever tell anything other than the corporate line.
Thank you John Katz , for painting my profession and peers with the broad brush of cowardace.
News for Nerds, my Ass!

PS -- Makes you wonder, how many people have to stave from lousy crop yields before food technology will be "okay" with Katz?
All search algorithms suffer from the same fundamental information problem -- insufficient information from the query. Unless the quantum computer is also a mindreader, it has no way of knowing whether the query "trains" has to do with railroads or wedding dresses.
For starters, much of the increased capacity for PCS (be it TDMA, CDMA, or GSM) comes from the smaller cell size, owing to the higher frequency (1900 MHz) / smaller wavelength of PCS. However, propagation at 1900 MHz is less favorable than at 900 -- more shadows and reflections/fading. Wideband FM would sound much, much worse than the PCS technologies in the same spectrum band. The reason that PCS is cheaper is simple supply-and-demand economics. Sadly, the decision to have three incompatible PCS technologies (done to keep the European manufacturers out of the US market, in retailation for Europe having done the same a decade earlier) means that PCS coverage will probably never be as extensive as AMPS, at least until we see tri-technology phones, or the marketplace kills off two of the three. -=paulf
Modern rails are welded together, but cast in such a way that heat expansion occurs orthogonally instead of along the direction of the rail. Also, modern railroad signalling systems use the track as a waveguide. So, sorry, bandwidth already in use! -=paulf
I wrote a paper on this topic for the 7th ARRL Networking Conference (available from TAPR). Briefly, at frequencies above 1 GHz, it begins to make a great deal of sense to take advantage of gain antennas and spatial diversity. With omnidirectional antennas, you're spewing RF everywhere, causing your network to extend over a larger than necessary area. Directional antennas reduce the spatial occupancy. If you're worried about interfering with omnidirectional networks, take advantage of the polar diversity and separation available to you at these wavelengths: omnis vertical, directionals horizontal. -=paulf, N9FZX
The Dish has a wonderfully colorful history, shrouded in the early days of the Cold War. Publicly, it was built for 6m radio occultation experiments for the Mariner Venus probes in the early 60s. The transmitter is a truly awesome entity, which was sadly rusting away the last time I saw it a decade ago. The single final amp tube was water-cooled using four truck radiators, and even the feedline was water-cooled -- as low as the losses were, there was so much power going through that waveguide that heat losses could (and did once) melt it.
The Dish also has a long history of satellite rescues, including one of the OSCAR ham satellites. As the Valley grew up and started becoming a broadband RF noise source, the Dish fell somewhat into disuse until a group at STARLAB devised a signal washing system (nice work Ivan and Co.). It has seen quite a bit of astronomical work since.
What you want is a PC104 motherboard with a flash disk (ala DiskOnChip), with a PCMCIA option card. Ampro makes both. The 486 CPUs are laptop variants which should reduce cooling requirements. Insert the WAVELAN PCMCIA adapter, and then remove the WAVELAN card from its housing. Remove the small omni antenna, replace with a short length of RG174 coax. Solder another length of RG174 to the +5V pad.
Find a good weatherproof cast aluminum housing (with rubber seals). Drill two holes for a pair of BNC connectors. Install the BNCs, solder down the RG174 to the BNCs. Etch a +5 Symbol on the housing for the power connector, and ANT for the other. Connect up a suitable onmi antenna and power, seal up, and enjoy.

Now maybe the Loc Nar will appear while I'm doing my natural energy lighting experiments! It's great to be Den!

The simple solution? Type in more words!
