So... Yeah...

My motherboard crapped out on me. $420 later I pretty much have a new PC that's actually faster than the one that died.

My motherboard is about four years old. I bought it when I built my rig. It was socket 939 which, it would appear, no one carries retail any longer. Sure, I could have paid $50 and got one online but, I supposed, it was time to upgrade. I knew that with a new board I'd need a new processor. NO big deal. Now I'm kicking it with an AMD 2.1 GHz dual core. I didn't anticipate having to buy new memory (2GB DDR2 down from my old 4GB DDR). Oh, and a new power supply. Apparently a 20 pin plug into your motherboard isn't as good as a 24 pin. So, now I have a new 550 watt power supply that's not as kewl as my old one because that one was internally lit - I have a window on the side of my tower. All my fans are LED lit as well. I still need to get some neon in there too.

So, motherboard dies, I need to get new motherboard, processor, RAM, and power supply.

The board is SATA but has one IDE chain. It didn't occur to me until I got home and installed it that I needed two (I'm not buying new SATA hard drives). Off to Newegg.com to order a PCI card that'll give me an additional IDE chain. So, no DVD- or CD-ROM support until Thursday. And wouldn't you know it? It appears AGP has gone bye-bye. So, my old video card is useless. Newegg.com again for a new PCI Express video card.

The lesson here?

Never get off the technology train. Ever. Replace one part with something newer and you gotta redo the whole stinking thing.

Polywell Update: Plasma!


The WB-7 team has produced plasma, and things are looking good so far:
"We're not out trying to make a big splash on any of this stuff at this point," Nebel said. But he said he's hoping to find out by this spring whether or not Bussard's concept is worth pursuing with a larger demonstration project.

The initial analysis showed that Bussard's data on energy yields were consistent with expectations, Nebel said.
This is very preliminary, but it's good to see they're making this kind of progress already. It sounds like the next few months could see a major announcement.

(via M. Simon)

UPDATE: The "larger demonstration project," as it is unassumingly referred to here, would be a truly world-changing device. Bussard was envisioning a 100MW reactor fusing hydrogen with boron-11 and generating current directly by running the the resultant alpha particles into a magnetic grid; because this produces very little radioactivity and eliminates the thermal cycle (steam turning a turbine) in which a large percentage of power is lost, it would be an order of magnitude cheaper than current commercial power sources. Bussard believed this could be done with a budget of $100 - $200M.

Even a smaller machine (perhaps 10MW) that only fused deuterium would be revolutionary, and perhaps still cost-effective given the efficiencies of an IEC reactor versus a tokamak. Bussard did not think an intermediate machine made sense, but depending on the available budget this might be the main attempt, or if rumors of Congressional interest are accurate, it might be done as a secondary project to the main effort.

Disappearing Car Door


This is probably not cost-effective, and I worry about how you get out if your car battery dies, but very cool-looking and extremely convenient in certain situations, as the video points out.

And yes, this is apparently for real.

Re-purpose your TV!

Right now this is only available for Mac users, but it has exciting implications.

 

What I’d like to be able to do is use photos or fractals or some kind of random visual in conjunction with music – rather like the old 60’s era light shows. Wouldn’t that be cool for a party? 

 

Or even when you’re by yourself and have your music station running on your cable or satellite.

Layered Defense


For the self-defense enthusiast on your Christmas shopping list, Amazon now offers the TASER M18-L.
The ADVANCED TASER M18L includes an optional laser sight to aid in aiming and uses a replaceable cartridge containing compressed nitrogen to deploy two small probes that are attached to the ADVANCED TASER M18/M18L by insulated conductive wires with a maximum length of 15 feet (4.5 meters).
Most people who would want this probably have a gun already, and it's just the thing to avoid killing a drunken in-law attempting an ill-advised Santa imitation. And it's probably only a matter of time before you can get it bundled with the perfect accessory.

There's an odd symmetry between this device and the recent Joe Horn incident, in which the Texas man shot and killed two burglars.
The 911 call came from a Pasadena, Tex., resident, who alerted police to two burglary suspects on a neighbor's property. Before he hung up, two men were dead by his hand.

The men were reportedly shot at a distance of less than 15 feet.
The short distance probably means they were approaching him, possibly with aggressive intent. The shooting appears justified, but given the uncertainty in that situation, one might like to have some kind of nonlethal option to subdue them at least available. We don't know all the circumstances involved, but for most killing two people is a heavy burden to bear, and it's possible that after what happened Mr. Horn wishes he had had that option at hand when he accosted the burglars.

What Should I Get?

Just like me, my computer is getting old and has started forgetting things. ;>)

 

I can’t give da ‘puter gingko biloba or brain exercises, so I’m going to be replacing it.

 

Thing is, in the four or so years since I got this one, the market has changed. Used to be you could go to Dell or Gateway and hook up with a decent system for around $300. Now they start at $600 and don’t even have any software! (Well, not the kind I need, anyway.)

 

My needs are less simple than they used to be. I’ve recently got an RCA Small Wonder video camera and am making lotsa videos of the grandkids.

 

I also need Publisher, or something like it. The ‘puter I have right now is the first ever that didn’t have it, and it’s getting old waiting until I get to work to use Publisher. Other than those two things, I don’t do much but word processing and internet stuff.

 

Last summer when I first started thinking about a new system, I had no need to worry about the cost – I was going to get whatever I wanted. Only I’ve since quit the big bucks job as of Nov 1, and I’m back to economizing again. Guess I shouldn’t have spent so much on Christmas (I did all my shopping in October) but who knew?

 

Even tho I’ve got an old A+ cert, and probably could, I really don’t want to build my own. I want something plug-n-play, out of the box. This is a desktop model I’m looking for.

 

I’m open to suggestions!

Things Looking Ugly For Vista


First there were all the DRM complaints, and now this:
Wellington, Fla.-based Devil Mountain Software ran several versions of XP and Vista through a test simulating common desktop computing tasks. It found the original Vista performed 50 percent to 100 percent slower than the prevalent XP Service Pack 2, or SP2.
I'll probably get a new Dell in the next couple months, and it will almost certainly be running XP, not Vista (still heinous, I know, but I'm too lazy to run Unix at home).

Hopefully, enough people will continue to shun Vista that it will never fully supplant XP.

UPDATE: As if on cue, Glenn chimes in with this related article. Seems Apple has its own Vista.

Polywell Funding Confirmed By Major Media


Most of those interested already know that Bussard's fusion project was funded in August, but this is the first published report from a major media organization that I've seen, and seems worth linking given the conflicting reports in the past:
Bussard received nearly $2 million under a U.S. Navy contract in August to continue work on an inertial electrostatic confinement reactor he had developed. The reactor uses magnetic fields to confine electrons, whose negative charge causes protons and Boron 11 atoms to fuse. The fusion sets off a chain of reactions that produces electricity.
Should the current project produce the expected results, Bussard had indicated funding might be available for a major project in the $100M - $200M range to attempt the building of a 100MW net power Polywell fusion reactor, which, if successful, would of course be a world-changing event. I'm actually now studying Forth, a computer language that might be used for the critical control software, in addition to some remedial physics/engineering, in hopes of perhaps being relevant enought to work on this project (should it materialize) myself, though that might be problematic in terms of my career/financial goals.

Discussion of Polywell continues in several forums. You can see the video of Bussard's Google presentation here.

Polywell Update: Tragedy, Hope


Dr. Bussard has died, a tragic loss for mankind. Fortunately, his work continues.

I had the good fortune to speak to Bussard several months ago on a radio program where he was invited to talk about the implications of Polywell fusion for space travel. As those of us who supported his efforts mourn his passing, we can take some solace in the knowledge that the attention we brought to the issue helped his project gain funding before he passed away.

The Golden Age of Piracy

Every culture creates a mythology or mythology unique unto itself. Some are a little more unique and/or derivative than others, but it always happens. With Americans, I would argue that we have created, via Hollywood, at least two instantly recognizable mythologies:

1) The "old west" 2) Pirates of the Caribbean

One might also add the tales of the American Revolution, many of which are apocryphal or probably false (like George Washington and the cherry tree), and also the entire concept of the super-hero (Superman, Batman, Spider-Man, etc.).

Anyway, without getting too in-depth on any of that I note that yesterday was "Talk Like A Pirate Day," a humorous "holiday" we've "observed" here on Dean's World for years now. Now the truth of the matter is that real pirates, modern or historical, is a wicked, disgusting career somewhere between street gang hood and mafioso or terrorist. It's not particularly funny either--murdering, raping, robbing, and pillaging people for fun and profit on the high seas is no more funny or admirable than murdering, raping, robbing, and pillaging people for fun and profit in other contexts.

Still, most mythology is based on something. For example, the "old west" in the United States is based on a very brief period of American history, lasting no more than 20-30 years, in the late 1800s in the Western states. Not unlike the legends of, say, Robin Hood or King Arthur, figures who probably didn't exist in reality but even if they did exist far greater in human imagination than in actual history.

A similar Hollywood/historical fiction is the idea of the "pirate." Having little resemblance to real pirates (who are, by definition, murdering, raping, stealing thugs), the "pirate" is a Hollywood movie/mythology that endures. Like "the old West" (which also existed, but for a very brief period), there was a "Golden Age of Piracy" in the Caribbean, wherein various governments basically gave a blind eye or even actively encouraged piracy on the high seas. For example, there actually was a dread Pirate Roberts, although his reality was somewhat at odds with the beloved "The Princess Bride" movie.

Mythology is almost always bullcrap, but that doesn't take away from my enjoyment of it. No, there was no Man of Steel. No, there was no Treasure Island. No, the Old West was nothing more than a brief period of perhaps 20, 30 years], mostly of ruffianshp and barbarism. If there was a real King Arthur (doubtful) he likely wore animal skins and ruled in a manner reminiscent of modern street gang rules. Such is the nature of history and legend.

Still, the legend of the romantic and perversely admirable pirate endures in the American lexicon. I can recognize and enjoy this even while recognizing that it's as full of crap as the average John Wayne movie. Still, there was a reality that underlay much of the mythology. See the history of The Golden Age of Piracy" for a bit more info." My own take is that modern-day terrorism should be viewed and treated much like piracy in the days of yore: pirates and terrorists are the acknowledged and proud enemies of civilization and cutthroats and murderers by definition, people who are at war with civilization by definition, and should be treated accordingly.

In the Sticks

Last night I moved my son into his apartment- he'll be attending Plymouth State University in Plymouth, NH and found an opportunity to live cheaply off-campus, so he jumped at it. As we unloaded the van and he and his roommate unpacked I reached for my cell phone to call home and let my wife know I would be later than I'd thought...

NO SERVICE.

I asked them about it and they both flipped open their phones...

NO SERVICE.

And so we finished and I headed home, trying not to giggle too hard at the thought of these two teenagers, children of the age of total connectivity, sitting in their new apartment up in the hills of Northern New Hampshire with no phone, no cable TV, no Internet, and a 30 minute drive to any place they might be able to avail themselves of such things.

The Cable and Internet won't be connected until next weekend. I figure he'll be home by tomorrow morning.

Al Gore on nuclear power

from his climate policy speech at the NYU Law School on Sep. 18, 2006.

Many believe that a responsible approach to sharply reducing global warming pollution would involve a significant increase in the use of nuclear power plants as a substitute for coal-fired generators. While I am not opposed to nuclear power and expect to see some modest increased use of nuclear reactors, I doubt that they will play a significant role in most countries as a new source of electricity. The main reason for my skepticism about nuclear power playing a much larger role in the world's energy future is not the problem of waste disposal or the danger of reactor operator error, or the vulnerability to terrorist attack. Let's assume for the moment that all three of these problems can be solved. That still leaves two serious issues that are more difficult constraints. The first is economics; the current generation of reactors is expensive, take a long time to build, and only come in one size -- extra large. In a time of great uncertainty over energy prices, utilities must count on great uncertainty in electricity demand -- and that uncertainty causes them to strongly prefer smaller incremental additions to their generating capacity that are each less expensive and quicker to build than are large 1000 megawatt light water reactors. Newer, more scalable and affordable reactor designs may eventually become available, but not soon. Secondly, if the world as a whole chose nuclear power as the option of choice to replace coal-fired generating plants, we would face a dramatic increase in the likelihood of nuclear weapons proliferation. During my 8 years in the White House, every nuclear weapons proliferation issue we dealt with was connected to a nuclear reactor program. Today, the dangerous weapons programs in both Iran and North Korea are linked to their civilian reactor programs. Moreover, proposals to separate the ownership of reactors from the ownership of the fuel supply process have met with stiff resistance from developing countries who want reactors. As a result of all these problems, I believe that nuclear reactors will only play a limited role.

discuss.

Polywell Fusion Funded By State Of California?


This could be what we've been hoping for.

I don't know much about the source, and I haven't seen it anywhere else yet, so I'm not quite ready to pop the champagne yet. Glenn linked it, which is an endorsement of sorts. I'll rely on his judgement as uber-techblogger for the nonce.

I'll expect we'll hear more within a week or so, assuming there's something to this.

Computer questions

So, When I press the power button on my current computer, I get a repeating long beep. And nothing else. This doesn't conform to any of the beep codes I know, or can look up. I figure it means that either my memory, motherboard, or CPU have died...

Since my current setup is about 4 years old, I decided to get all new everything. I'm going from: AMD 3200XP with 1gig of DDR 333 RAM To: Intel Core 2 Duo (E6300 2X1.86GHz) with 2 gigs of DDR2 667RAM (with this motherboard)

My questions are: 1) How much more does my new system rock over my old system? That's not bragging, that's a real question.

2) Will my Serial ATA 1.5Gb/s connectors support my old ATA100 hard drive? What about my DVD drives-- the ones that are on the same circuit as my hard drive?

3) I've heard that Intel is significantly cooler than AMD, is this true? Does anyone know if this motherboard has a built in thermal gauge?

Anything else I should be thinking of? Thanks in advance!

Polywell Fusion Update


Here's a nice little video that graphically illustrates how the magnetic well in the Polywell IEC fusion device forms (there is now proof it does form). The little flashes later in the video represent ions fusing. Here is Bussard's original presentation to Google, which sparked interest in the Polywell concept.

This extremely technical discussion, with lots of scary equations, is apparently the key to whether IEC fusion of one type or another will pan out and usher in a new age of cheap energy abundance, or just waste everyone's time and money on a wild goose chase. It applies to both of the currently proposed IEC fusion machines are (Bussard’s Polywell and the Tri-Alpha colliding beam machine being built by Rostoker/Monckton). It’s from 1998, and is essentially a debate over whether the magnetic field in the Rostoker/Monckton colliding-beam IEC fusion device can reduce the thermalization (the tendency of the system to collapse to thermodynamic equilibrium). (Another issue is discussed as well, but it pertains only to the colliding-beam version.)

Rider’s earlier paper, cited by Nevins, supposedly proves the magnetic field cannot affect the entropy of the system. Rostoker/Monckton claim that Rider and Nevins used the wrong equation to describe the situation in an IEC machine, choosing conditions that don't reflect the reality of these devices. (Bussard has not presented a paper as of yet, though we might get one this year, but apparently makes essentially the same argument.) These are all serious scientists. There is apparently no definitive reference that resolves the difference of opinion. Most likely we’ll have to build the machines to know who’s right.

M. Simon of Power and Control is attempting to design a WB-7 Polywell fusion device, based on Bussard’s “Valencia papers” describing his work and some help from Tom Ligon (who worked with Bussard), that would provide definitive, repeatable, testable proof beyond any doubt. Effort is ongoing in this thread, with notes in this forum as well. Kinda neat, really; it’s a real Army of Davids kind of approach.

Of course, Tri-Alpha just got $40M to build their demo model, so they’ll probably be first past the post if they have a viable path to economical fusion power. But things will get pretty crazy (i.e., billions being thrown around at anyone with pretty PowerPoint slides, a la the 1999 Web bubble) if anyone can prove IEC fusion works, especially with oil staying over $70/bbl. Tri-Alpha has said they see commecial power within 15 years, so presumably that money is going to build a smaller prototype model, which is probably a 1-3 year project. Meanwhile, Bussard has hinted funding for his design may be forthcoming, so it could be a very interesting next few years.

Little Brother


Via Glenn, an interesting, somewhat frightening proposal to mimic Britain's system of government cameras.

I would argue we could greatly benefit from cameras, but not the kind Britain has. We need individuals with cameras – to watch the police as well as criminals.

Just imagine what will happen when data storage and camera tech is cheap enough that it’s trivial to walk around carrying a continuously updated video recording of the last hour or day you’ve experienced, perhaps even with a copy held remotely for security so it can't be seized by the offendor. With face recognition and biometric technology, non-consensual crime could become much more difficult.

I've got an irritating problem- I moved 3500years.com to a new host, and now all the old posts have question marks (???) where there were quotation marks, apostrophes and ellipsis's.

I'm running MT 3.17 and I tried adjusting the character encoding in the mt config file, but no luck. What I've finally done is export my entries, paste it into notepad, then I used find/replace to swap curly quotes and apostrophes with straight ones and ellipsis's with three periods.

The Problem With The Space Shuttle

For a bracing look at the real flaws of the space shuttle from day one, I've never found anything better than this:

Beam Me Out Of This Death Trap, Scotty.

It was first published in 1980, before the first shuttle launch, and it's hard to find anything about it that didn't turn out to be completely correct. If anything, it underestimated what a boondoggle the space shuttle has been.

The space shuttle has proven much less economical, much less reliable, and much more dangerous than any of the launch systems it replaced. And has proven to be incapable of most of the things it was supposed to be able to do.

It may be hard to admit all that while being impressed with watching it take off and land, but that's the hard truth.

We need to scrap these obsolete death traps. We can have much better, for much cheaper. It only requires the will.

Dave Adds: For something truly revolutionary, check out Tom Ligon's ISDC presentation on how a Polywell fusion drive could allow us to start colonizing the solar system in our lifetimes. A permanent moonbase for $12B, a Mars base for $15B!

Polywell Fusion Update


Since previously posting on the Polywell fusion project after seeing Bussard’s Google presentation on his Polywell fusion reactor design, I’ve been trying to read all I can on the subject, and have been surprised how few unaddressed technical objections seem to exist. At first I assumed this technology was a very long shot, as such prospective technologies generally are, but now I’m starting to wonder.

This is apparently not particularly novel physics or engineering; inertial electromagnetic confinement fusion has been well-understood since Farnsworth’s work in the 1960s, but was abandoned (at least for power generation) because it appeared electrons hitting the grid and bremsstrahlung losses would always prevent IEC fusors from generating net power. Bussard’s insight and achievement was the development of a “gridless” device wherein the physical grid is replaced by magnetic fields, allowing electrons to recirculate 100,000 times rather than being absorbed by the grid. Additionally, according to Ligon the problem of such systems collapsing to equilibrium is solved by the fact that the electrons only maxwellianize at the “top” of the well as they bunch up, and Bussard calculates bremmstrahlung losses will be small enough for an IEC device to achieve net power. Here’s the best overview of the technology I’ve run across.

Dr. Bussard was interviewed on the radio on a space program the other day, and I got a chance to talk to him and his colleague Tom Ligon briefly (thanks M Simon for posting the heads-up in the Yahoo IEC Fusion group). Bussard told me his focus now is to raise the $5 million or so necessary to build an improved WB-7 machine, which should have even better containment than WB-6 and produce enough fusion data that other experts can be assembled to examine the device and pronounce the concept sound, after which enough publicity should arise that the necessary $100M - $200M funding for a full-scale, net-power model becomes feasible (for comparison, the ITER machine will cost more than $10 billion and is only a prototype).

In a possibly noteworthy development, John Carmack, programmer of Doom and Quake fame and rocketry enthusiast, has become aware of Bussard’s work and expressed some interest in building a Polywell fusor. He probably has the resources to build a working Polywell prototype on his own, but as he has said he is at the bottom of a very steep learning curve.

One of the most exciting aspects of the technology is the potential to generate electricity directly (rather than heating water and running it through a turbine) by converting alpha radiation created by an aneutronic fusion reaction, most likely the “p-11b” reaction whereby boron-11 is fused with hydrogen, yielding three helium nuclei at high energy (alphas). Of course, the energy levels for that reaction are much higher, so the first prototype Polywell reactors may be the usual boring thermal designs powered by deuterium/tritium fusion, but an aneutronic direct-power device has huge implications, especially for space travel.

Accepting Bussard's claims that his WB-6 fusion device did produce neutrons and that the energy gain will scale as the 5th power of the radius of the device, the stumbling block appears to be the lack of a functioning device (WB-6 was destroyed in one of the last test runs) which the scientific community can study and validate. Once again, Bussard’s company is soliciting donations to raise the ~$5M to build the WB-7 device (note: the project was funded by the Navy in October 2007; Bussard passed away but the work continues).

Is This A Cheap, Workable Fusion Reactor Design?


Google is wondering if Robert Bussard (whose name is well-known to sci-fi fans) has a viable and inexpensive design for a fusion reactor in his Polywell fusor.

Bussard argues that current tokamak designs based on thermal triggering of fusion (such as the massive $10B ITER project) are probably never going to be economically viable, because confining the plasma is so incredibly difficult, physics dictates that such reactors have to be huge to be efficient, and neutron escape means such designs will always be dangerous and difficult to maintain. But confining electrons is much easier than confining ions, as electrons are much lighter, so a working electrostatic confinement fusion reactor would be much smaller and much cheaper.

It's long been known you can create very small amounts of fusion with an electrostatic confinement device (in fact, you can make a simple IEC reactor for a few hundred bucks), but Bussard's project marks the first time anyone has been able to create a gridless device design that generates a magnetic field with electron losses low enough to produce fusion energy that, scaled into a larger version, might make a viable power plant. Unfortunately, government funding was cut in 2006 (the lab's equipment now sits at SpaceShipOne engine maker SpaceDev), but Bussard believes the WB-6 model proved the concept works, and that he could build two small prototypes for another $5M that could then be scaled up to working power plants.

Bussard claims the physics problems are solved and only the engineering issues remain to be worked out, at an estimated cost of about $150 - $200M and a time frame of 5 years. That's expensive, but peanuts compared to the 50 year, $10-25 billion time frame to a working thermal fusion reactor — and the implications if the device works are nothing short of staggering: our dependence on Mideast oil for energy would quickly evaporate, energy prices would fall precipitously, space travel would become orders of magnitude cheaper. At the very least, the results so far seem to merit funding Bussard's plans for a WB-7 and WB-8, which would further prove out the concept and pave the way for a working full-size model, at a cost of about $5M over one year.

(Previous blogging on this subject by Mark M. Simon at Power and Control; more links here, and a Yahoo group dedicated to IEC fusion is here)

New Media and the Conversation

It’s a common thread in the comments section of many a political and cultural-issues website: blogging is useless. It affects nothing, changes nothing, has no impact on the greater issues of our time. When anonymous cyber-commentators fail to appreciate the fact that if blogging is useless, commenting on blogs is less than useless, irony is certainly dead—however, that’s not my point. I want to talk about what I call ‘the Conversation’.

The term first occurred to me when we started getting television out of Iraq again. Most if not all of the Iraqi satellite channels went offline during the first year of the war. Then, in the autumn of 2004, we started getting a signal: a simple computerized list of displaced Iraqis seeking their relatives that would scroll down the screen as Iraqi folk-songs played in the background. Though we didn’t know who these people were, though a highly censored episode of Friends was playing on one of the culturally schizophrenic channels out of the Gulf, it seemed all of Cairo was glued to this timid little channel beamed from Baghdad. It was a sign; the olive branch retrieved from a flooded world, the simple message that the entire Arab world had been waiting for: ‘We’re still here’. People watched that scrolling list of names and wept.

And then, there were pixels: Deus ex machina, God from the machine. One little signal out of Baghdad had done more to reassure people that normalcy might again be possible than a year of press releases. I realized that what was truly crucial to the digital age was not information but conversation: a vast, real-time, evolving dinner table discussion about the state of the world. It was made up, by and large, of the voices of ordinary people with ordinary concerns, not grand theories. Bloggers, though often crude, formed an essential part of that conversation. Sure, blogging probably doesn’t change very many minds about very much. It probably hasn’t swung very many votes. But what it has done and continues to do is erode individual prejudices. The blogger effect is the butterfly effect: on the information superhighway, one person encounters another person of wildly different politics and disposition, and because the anonymity of the internet provokes a candor you don’t get anywhere else, comes to respect him. They don’t agree. They’ll never agree. But what they will do is make an effort to understand each other.

Those who run down the blogging phenomenon and new media in general misunderstand the nature of change: they expect it to come all at once, in a wave, as a sudden overturning. But more often than not, sustainable change happens one person at a time. There will be no revolution that reconciles East and West, no great détente that resolves Left and Right. Differences will never be eliminated, but they can be understood. In this capacity, the Conversation is not only far from useless, it is essential.
