Comment Re:Since nuclear is "too cheap to meter"... (Score 2) 258

"I would say my father was referring to fusion energy. I know this because I became my father's eyes and ears as I travelled around the country for him."

So, a nuclear advocate covers for his nuclear advocate father's boneheaded remark pretending that nuclear energy would be cost effective. Or at least that's the assertion of someone named "Blubbaloo" who is the person who created the "too cheap to meter" wikipedia page. It is the only wikipedia entry that "Blubbaloo" has ever seemed to have made. And one that he seems to guard very carefully. And the only person who has ever disputed the meaning of Strauss' statement was his nuclear advocate son.

It's funny that a "physicist" wouldn't be able to understand the concept of externalities.

Here's a little detail from the talk pages of that very interesting wiki artifact:

We should not discount the popular impact of this statement. I added "Newspaper articles at the time..." and I wonder why there is any question about Strauss' meaning. Clearly the New York Times, writing about the Sept. 16 1954 speech, understood that Strauss was referring to the entire atomic energy program. Even if Strauss was misunderstood, he did not take any great pains to clear up the record. User:wkovarik -- Bill Kovarik, March 15, 2011.

A direct copy of the entire speech would clear up most of the questions around the usual (often mangled, as the one included today is) quotes. (Did the NYT reprint the entire speech or just portions?)
Robert Pool, 1997 p.71,[1] quotes this preceding line, often left out: "Transmutation of the elements--unlimited power ... these and a host of other results all in fifteen short years. It is not too much to expect that our children...." etc. There's little question that Strauss was waxing poetic; more to the point: many sources say he was encouraging science writers to promote fission power to these ends. Which completely makes sense considering their need to create more plutonium.
His view was not widely shared; in 1951, General Electric's own C. G. Suits, who was operating the Hanford reactors, said that "At present, atomic power presents an exceptionally costly and inconvenient means of obtaining energy which can be extracted much more economically from conventional fuels.... This is expensive power, not cheap power as the public has been led to believe."[2] Twang (talk) 16:53, 14 May 2011 (UTC)

"many sources say he was encouraging science writers to promote fission power to these ends."

Tobacco mixed in is definitely a European thing. So much so, that they can't imagine smoking a "pure" joint. It's a real bummer to have someone hand you a jay, and cough your lungs out because some jerkwad mixed in half a Marlboro. I got started smoking cigarettes that way. Thanks, jerks.

We will not solve the problem with illegal immigration until we figure out how to do something sane instead of the War on Drugs. Right now the unintended consequence of the War on Drugs is that south of the border, drug lords are about as well (if not better?) funded as the governments, destroying the local economies. Some of the people seeking jobs in those economies end up coming to the US in search of work.

So, a driverless car that can't handle rain or snow or recognize a pothole is going to be perfectly safe around pedestrians and bicyclists?

Stop yourself. Nobody reading Slashdot today will live to see ubiquitous driverless cars.

Comment Old Shite (Score 2) 635

I really, *really* liked my late 1970's-era 6809 system. 64k of RAM, custom graphics and sound cards of my design, timers, serial port, multiple floppies. I thought it was getting old in the tooth (it wasn't, it still works, should have had more faith I suppose), so I wrote an emulator for it -- the entire system, hardware, software, a front panel (which the original didn't even have) everything. Still works great, but due to the increase in CPU power over the years, the emulator is one heck of a lot faster than the original hardware. You can use it too, if you're so inclined and you're running some version of Windows, XP or later (might still work under Windows 95 and/or 98 for that matter.) Includes various compilers (Dugger's c compiler, for instance), forth, assembler, cross-assemblers, linkers, basics, some arcade video games that used the graphics hardware, and probably the vast majority of the commands that were available for the DOS, which was FLEX09. Percom PSYMON monitor. If you ever wanted to play in a nice, safe assembler sandbox, it doesn't get any better than the 6809. It just gets faster and wider.

For linux, the answer is Midnight Commander. Between the very nice editor and the dual-pane do-lots-of-things text mode interface, it's still my go-to under linux, I even use it on the Mac. Thankfully, they've kept it reasonably up to date, although making a native mac version without inflicting a much broader *nix ports package on the system is a real pain in the butt.

For the Mac, I use both of the above, MC natively and my emulator under a VM running a network-isolated XP, and I still run a PPC version of my HP-48G, which, I'm afraid, has made any other calculator use not only pointless, but nearly impossible. I also have two of these calculators in hardware, both of which still work fine. Because Apple dropped PPC support at OSX 10.7, my daily driver machine still runs OSX 10.6 and is likely to continue to do so unless I can find a native version of the HP emulator for Mavericks. When I decided to move past OSX 10.6 (Mavericks is actually quite nice, finally), I bought a new machine and plopped it down in my ham shack.

Ham radio: Easy. My Palomar loop antenna. This tiny (about a cubic foot) antenna system has pluggable loops for 150-500 khz, 500-1700 khz, 1700-4000 khz, and 4000-15000 khz. I like to drag it out into the unimproved areas a few tens of miles from here where there are zero power lines, telephone cables carrying data, neon and other signage, plasma TVs, buildings and so on, and enjoy amazingly good, noise-free SW and amateur radio reception on the radio in my truck without having to set up a physically large and cumbersome antenna. I also have a Panasonic RF-2200 portable analog radio that I take on trips. Both of these are pretty old, tech-wise, but both remain in regular use and have stood the test of time very well indeed.

Music: A Marantz 2325 stereo receiver and a pair of Marantz HD-880 speakers. Not only does this setup sound nothing less than awesome, it eliminates the tedious menu surfing that more modern gear forces upon us. Everything's on a front panel knob. Everything. I have (very) modern gear in the home theater, but in my office, the old Marantz blue face remains king.

Lastly, I still have, and continue to play, a 1950's Fender Stratocaster guitar. I have a fair collection of more modern guitars, but the strat's neck is still the best of all of them. Luckily, for most of my life I've been a casual enough musician, and have spent enough time on other guitars, that I've not had to have the thing re-fretted. I don't look forward to that. I can't imagine it'll be the same. Of all the old stuff I have, this is the thing that has not only kept its value, but appreciated far beyond any dollar figure I could ever have anticipated. Not selling it, though. Ever. :)

Comment Wringers on washing mashines (Score 1) 635

The old technology I am giving up are the wringers on top of washing machines.

They're dangerous (you can get your fingers caught) and they mess up more delicate fabrics. Also, the newer washing machines with the agitators that churn the wash around do just as good a job.

Also, zippers. Velcro is much easier to work with and it never gets stuck and it doesn't hurt as much to snag your dick on velcro.

Dr Manhattan is unlikely to come into being from energetic mouons interacting with fissile reactor fuel rods.

I'm sure they said a spider-man was unlikely to come into being from being bitten by a radioactive spider, too. But guess what happened.

Either way, as someone who doesn't know from nothing, I'm completely in favor of bombarding nuclear rods with muons. Because I like saying "muons". "Muons...muons..." If you watch yourself in the mirror when you say "muon" your mouth makes a little kissyface. Fun!

Now please excuse me. This bottle of single-malt isn't going to drink itself.

Comment Image processing (Score 4, Interesting) 181

I use -- and write -- image processing software. Correct use of multiple cores results in *significant* increases in performance, far more than single digits. I have a dual 4-core, 3 GHz mac pro, and I can control the threading of my algorithms on a per-core basis, and every core adds more speed when the algorithms are designed such that a region stays with one core and so remains in-cache for the duration of the hard work.

The key there is to keep main memory from becoming the bottleneck, which it immediately will do if you just sweep along through your data top to bottom (presuming your data is bigger than the cache, which is typoically the case with DSLRs today.) Now, if they ever get main memory to us that runs as fast as the actual CPU, that'll be a different matter, but we're not even close at this point in time.

So it really depends on what you're doing, and how *well* you're doing it. Understanding the limitations of memory and cache is critical to effective use of multicore resources. You're not going to find a lot of code that does that sort of thing outside of very large data processing, and many individuals don't do that kind of data processing at all, or only do it so rarely that speed is not the key issue, only results matter. But there are certainly common use cases where keeping a machine for ten years would use up valuable time in an unacceptable manner. As a user, I am constantly editing my own images with global effects, and so multiple fast cores make a real difference for me. A single core machine is crippled by comparison.

Comment Sources of water (Score 1) 708

The moisture source for lakes and rivers is -- inevitably -- precipitation over lands upstream. Either as direct runoff, or as recurring eruptions from underground aquifers. If the prevailing winds don't bring the more humid air over the cooler, higher landscape, sure, you'll see drought. But you'd see it anyway, more heat or not. When the prevailing winds are bringing more moisture over those same types of terrain, you're going to see more precipitation, not less.

The historical record bears this out. When the earth is warmer, we get (a lot) more plant growth. That's simply not going to happen if the precipitation is reduced for any reason. And, at least as far as I am aware at this time, there is no mechanism that would cause reduction in precipitation. Warmer air holds more moisture, yes, and that effect is in full view in the tropics -- with deluge level rainfall when that moist air hits colder atmosphere and the moisture inevitably precipitates as rain. 400 inches / year as opposed to about 100 inches / year in otherwise similar temperate regions.

I would certainly agree that if the wind patterns change, then the rainfall will too. In both directions. But it seems a little farfetched to say that such changes will result in a consistent decrease in winds traveling onshore. What would such a claim be based upon?
