I know you're thinking about a MacBook Pro. I bought a 15-inch about a month ago, transferred over from a PowerBook, and haven't looked back. I've decided against Parallels Desktop, mostly because I use Windows mostly for games, and that means dual booting for the speed. I had used VPC on the PowerBook, but that was because my PhD research had used Windows, and I didn't want to lose access to it. Moving that over was trivial. The main downer was the extra cost, but Macs last longer than Windows machines and cost less to maintain, so it's basically pay me now or pay me later--it'll cost more later. And they're more secure and look cool.
Things I've done: 1. Got 2GB of RAM and 160 GB of disk space. Used Bootcamp to install Windows XP Pro on a 32GB partition. 2. Bought an extra battery and power adaptor for travel and work away from home. 3. Bought an Apple modem for dial-up. 4. Installed Norton Antivirus (NAV), Stuffit, Yojimbo, BBEdit (for web page editing), GraphicConverter (graphics editing), Interarchy (ftp), MacSoup (a news reader), Firefox (in addition to Opera and Safari), NetNewsWire (RSS), R (to do statistics), eclipse (Java and C+ + IDE), MS Office, fink (a package manager for UNIX software), FinkCommander (to run fink), X11 (from the install disk--you have to search for it), the development packages (also on the install disk), and PGP 6.5. 5. Paid for three years of AppleCare. 6. Configured it so that root commands were executed using sudo--no root account. Used the ipfw firewall that Apple enables by default and locked the machine down for the most part. 7. Programs I run at log on include Terminal, Activity Monitor, Yojimbo (hidden), Console so I can monitor the log for anomalies, and X11, plus the ones installed by NAV, Stuffit, PGP, and other programs.
Running Windows XP Pro, I've learned I need to make sure my USB keyboard is powered--otherwise it drops out temporarily from time to time. This is not a problem with Mac OS X, so I suspect this is a driver issue that will be fixed with the next release of Bootcamp. When you're using the Apple Modem, *disable* the Airport and Blackberry devices. Also, make sure your configuration is locked down and protected if you're exposed to the Internet.
Do a full backup of both sides and update it from time to time. I use Retrospect.

Subject: Troops to Teachers
"Since its inception in 1994, the Troops to Teachers program has been an unqualified success. Over the past 12 years, at least 10,000 former military members have transitioned to second careers as educators at the elementary and secondary levels. Schools involved in the program have been almost universal in their praise of Troops-to-Teachers participants. More than 80% are male (providing an important role model for students); many teach science and math (high demand subjects) and virtually all of these teachers bring a badly-needed sense of discipline to the classroom.
Unfortunately, according to Air Force Times <http://www.airforcetimes.com/story.php?f=1-292925-2384270.php> , the Troops to Teachers program has hit a snag. A new interpretation of the 2001 "No Child Left Behind" act has placed limits on which schools can participate in Troops to Teachers, greatly reducing employment opportunities for prospective educators. Wisconsin Republican Congressman Tom Petri says the "new" interpretation limits the program to schools with more than 10,000 students, or those where more than 20% of the student body live below the poverty line. Previously, Troops to Teachers was open to "high need" schools, without any specific numerical requirements."

Subject: wolf-dog rescue
Dr. Pournelle, you've probably seen this already, but in case you hadn't...
Robbie Walker Wilmington, NC
One of the more interesting ideas I've seen of late is fermentation of synthesis gas (from biomass gasification) to produce ethanol: http://www1.eere.energy.gov/biomass/synthesis_gas_fermentation.html
"Biomass can be converted to synthesis gas (consisting primarily of carbon monoxide, carbon dioxide, and hydrogen) via a high temperature gasification process. Anaerobic bacteria are then used to convert the synthesis gas into ethanol. Bioresource Engineering Inc. has developed synthesis gas fermentation technology that can be used to produce ethanol from cellulosic wastes with high yields and rates."
"After gasification, anaerobic bacteria such as Clostridium ljungdahlii are used to convert the CO, CO2, and H2 into ethanol1. Higher rates are obtained because the process is limited by the transfer of gas into the liquid phase instead of the rate of substrate uptake by the bacteria."
"BRI has developed bioreactor systems for fermentation that results in retention times of only a few minutes at atmospheric pressure and less than a minute at elevated pressure. These retention times result in very economical equipment costs1,2. The biocatalyst is automatically regenerated by slow growth of the bacteria in the reactor."
There's a lot of biomass out there and it costs to get rid of it; it is certainly worth while looking at ways to make the process an energy source rather than a sink. How significant a source seems to be a matter of details and efficiencies, and I have not been following those developments.
Subject: Insignia of Emperor Maxentius unearthed
Now this is interesting:
Insignia of Emperor Maxentius unearthed
Archaeologists have unearthed what they say are the only existing imperial insignia belonging to Emperor Maxentius — precious objects that were buried to preserve them and keep them from enemies when he was defeated by his rival Constantine.
An imperial scepter with a carved flower and a globe, and a number of glass spheres, believed to be a symbolic representation of the earth, also were discovered.
The items, inside wooden boxes and wrapped in linen and silk, were found buried at a sanctuary last year and have since been restored and analyzed. The depth of the burial allows experts to date them to the early 4th century A.D., ministry officials said.
"These artifacts clearly belonged to the emperor, especially the scepter, which is very elaborated, it's not an item you would let someone else have," Clementina Panella, the archaeologist who made the discovery, said Friday.
Panella said the insignia were likely hidden by Maxentius' people in an attempt to preserve the emperor's memory after he was defeated by Constantine I in the 321 A.D. battle of the Milvian Bridge — a turning point for the history of the Roman empire which saw Constantine become the unchallenged ruler of the West.
Excavations on the Palatine in recent decades have turned up wonders such as the house of Rome's first emperor, Augustus. Experts said that much has yet to be uncovered, hidden in underground passageways.
The particular item offering Un jobs may have been a scam, but the salaries seemed a little low to me. Why? Back when I worked in DC 20+ years ago I had a patient who took a job with the UN for $300K, for doing precious little.
I'm sure you don't care to do any spadework on this trash, but I have seen no evidence that working at the UN entails any sort of financial hardship.

Subject: Hole Through the Earth
I was interested to read "Jim's" response (in your Sunday mail) to my question of the water level in a pipe drilled through the center of the earth from my backyard to the Indian Ocean. His answer (that the water level would end up at the mean sea level) sounds reasonable.
But then I got thinking: if the force of gravity is what makes water fall down a pipe, and the amount of gravity is a function of the mass of an object (Jupiter having more gravity at it's surface than the Earth due to Jupiter's mass): what is the amount of gravity at the exact center of the Earth? Is the gravitational force zero? And if so (assuming no other external forces such as the forward motion of the water as it's falling down the pipe to the center of the earth) : if gravity makes the water fall down to the center of the earth, what makes the water fall 'up' to the mean sea level in my backyard? Wouldn't the water stop at the center of the earth?
I leave that question to the much smarter brains of your readers.

I used to get involved in these discussions but I leave them to physicists now. If you want to do a thought experiment, try to imagine what materials could bound a hollow space in the center of the Earth. I want some of that...
From another discussion:
The question is whether "Permanently Advantaged" and "Permanently Disadvantaged" groups will live together in a "First World" country or a "Third World" country. At 13% permanently disadvantaged minorities, America is pretty much a "First World" place. At the ratio that obtains in Zimbabwe, one gets "Third World" conditions. The demographic explosion among recent illegal immigrants is going to force "First World" America to either do some very ugly things to keep on the right side of the "Tipping Point" demographically, or to accept some very ugly things (initially becoming like Brazil) by not acting.
Either way, it will be the children of our Permanently Disadvantaged Families (PDFs) that will be the innocent victims caught in the crossfire when First World America either does (or even does not) act, because they will be the vanguard of the group dropping into Third World conditions.
From another discussion:
It is true that their fertility rate is low, but their population is still rising, perhaps due to carefully controlled immigration. I can't find any immigration figures, but I'm pretty sure the maid who cleaned my hotel room was an immigrant from China. She spoke no English at all (not even numbers), but could write Chinese characters, through which we (barely) communicated.
If they are maintaining population thru that source I would have no worries for the future. ---
As a sign of the changing times we live in, on Sunday I sat next to three Chinese girls (about 20?) on the train from Narita to Tokyo. They were dressed in *very* expensive-looking, fashionable clothes and were taking pictures of themselves the whole time. They were probably in Tokyo to go shopping, and it looked like it wasn't the first time, because they paid no attention to train announcements. They knew where they were going.
Until recently there were no Chinese tourists in expensive Japan and certainly none dressed in clothes that could not be bought in a K-Mart blue light special.
I pointed out to my son that 30 years ago their parents were probably eating rats.

Mail tonight. There's a new diatribe by Joanne Dow on her page. For the record, I don't agree with her generalizations, but it's useful to collect these events to show what's happening in many places. And to my Turkish friends, I understand that Turkey is a secular state and sharia does not apply there, and the Army enforces that part of the Constitution. I have said before, I have great sentimental attachment to Turkey and the Turkish Army since the Korean War.
for Mr. Hellewell:
1) Gravitational forces at the center of the earth are (approximately) zero, because the source mass (the bulk of the earth) is symmetrically distributed in all directions.
2) The inflow is buoyed back up to surface level on the other side of the hole by the momentum of the inflow. The flow will of course cease (subject to damping, which may be considerable) when the weight of the water on the inflow side equals the weight of water on the outflow side.
3) For a rough (and hopefully correct) first approximation physical model: Assuming linear decrease of gravity with distance from the center (I haven't seen the computation since college and don't want to complicate the first approximation), so that the mean acceleration is g/2, the time of inflow to the center of the earth is about
t=sqrt(2R/(g/2))=sqrt(4R/g)=sqrt(4*6300000 m/10 (m/s/s))=1587 s
and the velocity of the head is about
v=(g/2)*t= 7937 m/s ~ 8 km/s, or nearly orbital velocity (as would be expected).
4) Sodium cooled tungsten/tungsten carbide ceramet (the sodium circulation system and the resulting mass and heat transfers while maintaining structural integrity is of course left as the next exercise for the interested reader, as is the possibility of using the superheated sodium vapor to power a turbine. Just make sure to engineer the system so that the water doesn't break through and contact the sodium....)
Thanks for bringing up the hole through the earth bit. You might ask Niven if scrith would work as a wall material, but I doubt it. Perhaps a tube of diamond? Oh, walls 10 feet thick ought to do. Yes, that would be one LONG molecule. (Yes, carbon is plentiful, but I wonder if there's enough carbon in the earth to satisfy this project.
I am so glad I looked this up. I remembered reading Martin Gardner's _The Annotated Alice_ when I was a kid and this "hole through the earth" topic came up. Gardner explained that, Lewis Carrol had included an interesting mode of travel involving a hole through the earth, falling all the way through with a transit time of 84 minutes. The neat thing was, the time was the same, no matter where the ends of the hole were. London to New York in 84 minutes, powered by gravity alone. Pretty neat trick.
Here's the note I read from Annotated Alice:
Gardner wrote about the hole through the earth in his Scientific American columns, Evidently, this topic is addressed on page 12 of The Scientific American Book of Mathematical Puzzles and Diversions.
Here's an interesting page here by Donald Simanek with various physics problems.
There's a related problem. In Chapter 7 of Lewis Carroll's 1893 book Sylvie and Bruno. The fictional German professor, Mein Herr, proposes a way to run trains by gravity alone. Dig a straight tunnel between any two points on Earth (it need not go through the Earth's center), and run a rail track through it. With frictionless tracks the energy gained by the train in the first half of the journey is equal to that required in the second half. And also, in the absence of air resistance and friction, the time of the journey is about 42 minutes (84 for a round trip) for any such tunnel, no matter what the tunnel's length.
here's the bit from _Silvie and Bruno_: http://www.hoboes.com/html/FireBlade/Carroll/Sylvie/ (I'd forgotten how much I loved reading Carrol)
I hope you found all that interesting.
Subject: Surprise: Oil Woes In Iran
December 7, 2006
- Roland Dobbins
This otherwise accurate account leaves out details of the key event: the overwhelming defeat in 1972 of a massive invasion from the north. You can find that account on this web site.
The potential domino effect in Iraq should concern us all. With Saddam in power in Iraq there was a balance of forces in the region. It may or may not have been unstable, but it was far less unstable than the present situation, where US withdrawal from the area might well trigger a race for the oil, with civil war in Iraq aided by outside forces. The most likely nation to profit from that would be Iran, followed by Syria. Turkey might well take advantage of the power vacuum to make gains in its war against Greater Kurdistan.
I did not want us in Iraq in the first place. I didn't want us there in the First Gulf War; I predicted then that the result would be far more than ousting one gang of thugs from Kuwait in order to restore another gang of thugs who were hiding in London casinos while we bailed them out. The First Gulf War wasn't finished, Iraq wasn't partitioned, the oil wasn't seized; the people of the South Delta were encouraged to rise up, then not aided, and were duly slaughtered to the accompaniment of the destruction of the marches, one of the greater planetary ecological disasters that the Friends of Man and the Earth seem to have forgotten.
The Second Iraq invasion was supposed to remedy those defects. It was possible still to use the Iraqi Army and the oil revenue to buy some stability in that unhappy land; I was hardly the only one to give detailed advice on what might be accomplished. None of that was done. Whether due to incompetence or venality (pump lots of oil and oil prices will fall) the execution was done about as badly as it was possible to do it. The oil fields were not secured. The Iraqi Army was not hired to keep order. A million young men were turned out without jobs but with weapons; no salaries, no prospects, no hopes, but lots of firepower. Predictably-- both predictably and predicted -- the looting began in their former barracks and went from there to government offices, then to any available target.
Nixon managed to implement his "secret plan" to stabilize Viet Nam: that was to build an Army of the Republic of Viet Nam that was capable, with US help, of resisting the worst that the People's Republic of Viet Nam could throw at it. ARVN could have resisted North Viet Nam forever at rather small cost to the United States. US casualties in 1972 were quite small, and those who helped ARVN resist invasion in 1972 were and are justifiably proud of their actions. Of course the victory was thrown away as Congress smelled Watergate blood and voted to cut off assistance to ARVN (except for a token 20 cartridges and 2 hand grenades per man). The Republic of Viet Nam accordingly fell, the dominoes collapsed, and the stage was set for the Killing Fields in Cambodia and the various purges in Laos; the reeducation camps, the boat people, floods of refugees.
You may recall the hopefulness that came with the Cedar Revolution in Lebanon. Israel killed the Cedar Revolution and left Lebanon in the hands of Hezbollah. They did this by expanding the war far beyond the local incidents that triggered it, humiliating the Lebanese national army, and throwing the Christians, formerly Israeli allies, into the arms of Hezbollah. They started a war they had not the stomach to finish. They took on obligations they threw over when the going got tough.
The United States invaded Iraq and so far has achieved chaos. If there is any national cooperation in Iraq it is directed towards getting the Americans out. Shiite and Sunni Militia hate each other, but they agree on one thing: Americans are fair game. And anyone foolish enough to cooperate with America becomes a collaborator, fair game for either side: because, after all, the Americans are going to cut and run and abandon the their allies, just as those left on the roof of the American Embassy in Saigon in 1975 were abandoned. We can always push the helicopters overboard to make room for more. We can afford it.
Is the Iraqi disaster retrievable? Yes, but only by American national commitment. We have to expand the war. Send in more troops, and begin to build a constabulary, a Foreign Auxiliary Force that will stay behind when we pull the Legions back to Kuwait and then back to CONUS. Make a serious effort to arm and train the domestic Iraqi forces. Recognize regional conflict and use money, lots of money, to settle conflicting claims and resettle families, not as helpless refugees but as citizens.
Will we do that with a Democratic Congress? Historically the Iraqi government can expect 20 cartridges and two hand grenades per soldier. Nothing more. The likelihood that America will decide on WARRE to restore our national honor and that of our Legions is no higher than the likelihood that the Senate of Rome would deal honorably with Caesar before he crossed the Rubicon.
If we will neither "stay the course" (a bad strategy; when you are in a hole the first thing to do is stop digging it deeper ) nor make the kind of commitment it would take to restore order (recruit Auxiliaries who will function as constabulary in Iraq and allow us to begin withdrawing the Legions; make it clear that we are there to stay forever; and do whatever it takes to get the oil flowing again so that Iraq can pay for its recovery) then what shall we do?
That is a matter for considerable thought; because once again, it involves a prior question. Who are we? What is our foreign policy? And what can be our foreign policy in a world in which we have made it clear that we accept no obligations no matter how we took them on? The world Post Iraq will be a different place. We need to think on that, and deeply.
More another time. See below for [invited] commentary by Joel Rosenberg. See also "Remembering Both Viet Nam Wars"
Subject: fertility rates
It was said of Singapore that
It is true that their fertility rate is low, but their population is still rising, perhaps due to carefully controlled immigration.
If they are maintaining population thru that source I would have no worries for the future.
The US population is still rising, even though births are hovering at the replacement rate. It takes about 20-30 years for the negative effects of inadequate birth rates to become obvious. Initially, it will appear beneficial, because the effort and cost of raising children can be put into other activity. Eventually, it cannot help but sap the vitality of a society.
As far as a general solution of trying to maintain a stable population through immigration, it can only work if the immigrants are assimilated. This rarely seems to happen, and we daily witness unrest among the helots.
Indeed. We sow the wind.
On a cheerier note

I invited Joel's comments on my notes on the Cedar Revolution and dominoes in the Middle East
As you know, I agree with you about Israel's action in Lebanon being a mistake; as I wrote when we were discussing it, it seemed necessary to me that they had to -- at a minimum drive -- Hezbollah north of the Litani, and destroy the extensive -- and expensive -- Hezbollah infrastructure in the south of Lebanon.
They didn't do that. I think that was a horrible mistake. It's going to be necessary for Israel to take on Hezbollah, and that means not trying to use the minimum force necessary in an effort to "do something," but enough force to both cripple Hezbollah militarily and make it clear to the rest of the Lebanese that allowing Hezbollah to go unchecked is suicidal.
Right now, the consensus in Lebanon is that allowing Hezbollah to go unchecked is less risky than restarting the Civil War; and, absent Israel making it more risky, they're right.
The Hezbollards in the south were allowed not only to escape, but under the watchful eye of the French, have been busy rearming themselves, using the French as mobile body armor as a check -- an eventually unsuccessful one, I think -- against the IDF coming back in and finishing the job. (There's plusses and minuses to that, of course. The war this last summer exposed the need for better training and equipping of the IDF reserves, as well as smarter political leadership; failing to have pierced the shell of the Hezbollah line in the south was a huge mistake, that will not be repeated even under the feckless Ohlmert administration.)
That said, I disagree with your analysis. For once, I don't think that the basis of that our ongoing disagreement about the importance of Israel as a US ally, and what policy considerations flow from that.
I think the heart of that disagreement is threefold:
Fold one: in my view, with the exception of getting rid of the Syrian occupation, the Cedar Revolution was a hoax, perpetrated by the Lebanese, on themselves. (Sort of Munich on the Levant.) Getting rid of the Syrian occupation was, of course, only supposed to be part of it; establishing a decent, civil, free society was the goal. (And, of course, the Syrian occupation is now over; it's been replaced by a Hezbollah-dominated local government. Lotsa luck, Lebanese...)
And the first step was to . . . bring Hezbollah into the government. Makes about as much sense as having the first step in, say, baking a cake being pouring in ammonia. The theory is that by bringing Hezbollah into the government, the Hezbollards would learn responsibilty, compromise, and accomodation.
Instead, what the Lebanese had was a simulation of a decent, civil free society -- with the Hezbollards allowed to do exactly what Arafat did in what was "Fatahland".
The theory, I guess, is that external forces (read: the US) would restrain Israel from removing Hezbollaland; the Christians and Druze could say, "Hey, do what you want to the Jews; just leave us alone." And, eventually, Hezbollah would be civilized. (I think some magic would be required for that next step.)
It didn't just fail to work -- although it did -- it was an invalid theory, which could never work. (Just as, somewhat more to the South, the notion that giving Arafat dominion over Judea, Samaria, and Gaza would civilize him, or that doing the same for Hamas would civilize them. It was the basis for what James Baker, the Donald Trump of international politics, has passed off as a diplomatic victory -- the Madrid Conference -- the notion that appeasement is the first step toward civilizing the uncivilizeable.)
Second fold: Israel hasn't had allies in Lebanon -- or anywhere else in the Arab world. There have been -- and are -- states, groups, and individuals where Israel shares a common interest, but the last of Israel's allies in Lebanon left Lebanon (many for Israel) when Israel withdrew from south Lebanon under Barak. The closest thing that Israel has had to an ally in the Arab world is (Trans)Jordan -- and that detente was achieved largely because Hussein (and now his son) are aware that their minority rule rests on both their domination of their "Palestinian" majority and on keeping Syria out -- and it was the threat of a counterattack by Israel that did keep Syria out during the whole Black September mess.
Third fold, related to the second: I think we disagree on responsibilities that Israel has undertaken to non-allies. I don't think there are many. Responsibility and authority must balance; unless Israel has -- and maintains -- authority over Lebanon, or (Trans)Jordan or the PA, such regions aren't Israel's responsibility. (Just was well; look at Gaza; it's doing even worse under Hamas than it did under Arafat's kleptocracy, and the trend is downward.)
Israel's best strategy, as I've been maintaining for years, is to build walls and buffer zones, respond disproportionately to attacks, but otherwise not try to manage the (largely miserable) lives of its neighbors, not because they wouldn't be better under Israeli rule -- one can make arguments either way -- but because Israel simply is not in a position to occupy and rule Lebanon or (Trans)Jordan . . . or Gaza, etc.
As to the Christians in Judea and Samaria, I think it's worth noting how the voting is going -- the voting with the feet, that is. There've been, as I understand it, quite a few Christian Arabs who have relocated to the Jerusalem suburbs, as close in as they can get, under the hope that when the final wall gets put in, they'll be on the side with the Jews, rather than their Muslim brethren . . .
Other than that, we're in complete agreement. :)
Actually we are not all that far apart. I recognize that much of the western response -- including my own -- to the Cedar Revolution may have been wishful thinking. The theory was that the Lebanese national government might be strong enough to weaken the militias and their hold on various regions, and begin nation building. There has been Lebanese nationalism in the past. What has been done can be aspired to.
That may have been wishful thinking but I do not think it was an impossible outcome. Alas, we will never know. The unfinished Israeli incursion with its strikes to the far north and the deliberate humiliation of the Lebanese Army and demonstration of its inability to protect the nation finished that off for good; what they killed may not have been viable in the first place. But it may have been. I can find knowledgeable people to argue on either side of it. More on your side than that of wishful thinking, I will concede.
Israel had a chance to develop strong alliances with the Christians in both Palestine and Lebanon. For good or ill they deliberately chose not to do that, with domestic policies that discriminate against Christians (see what happens when you want to donate equipment to a Christian university in Israel; and what happens to missionaries there). I think this was a major blunder. The Christian Arabs had no reason to love the Muslims after seven hundred years of Muslim rule. But that is water over the bridge. What is done is done.
I do believe that Israel has the responsibility to leave its non-Palestinian neighbors in a more stable configuration than they were before Israel sends in the IDF. As to what to do about Gaza, Judea, and Samaria, as I told President Ezer Weizmann while he was in office, I do not know how to solve the problem. I don't think Israel knows how to do it either. Since my visit with him was as part of an overtly Christian group, it should be evident that he wanted closer relationships with Christian Israelis. His frustrations at some of the actions of the government were expressed with considerable color. One difficulty is that the devil is in details that are inextricably entangled in politics: such matters as the petroleum monopoly are one example.
Nor are we in much disagreement about the right policies for Israel, but we may disagree on just how disproportionate a response ought to be. I agree entirely that you do not allow the other guy to set all the rules. On the other hand, you do not ordinarily use howitzers to combat a single sniper holed up in an apartment building; or bomb Beirut because border crossers kidnapped two soldiers. There is disproportion and disproportion.
As always I value your views.
Attacking "free trade" might have some merit if "free trade" was the problem. However, the global system of relatively free trade died some number of years ago. Now we have a system of "exchange-rate protectionism". These are not my words (although I strongly agree with them). They are from a rather interesting paper written by Martin Wolf ("Will Asian Mercantilism Meet its Waterloo?" http://www.pc.gov.au/lectures/snape/wolf/wolf.pdf).
[Peter Schaeffer adds here for this publication:
"Martin Wolf is almost certainly the foremost economic journalist in the world. I am not saying that he is always right (as I see it) or that I always agree with him. However, he is the only journalist I know of who could produce the presentation (three parts) linked to here http://www.rgemonitor.com/blog/setser/122822" ]
The reality is that many of our trading partners (and not just China) have found a new form of tariffs/protectionism that they can get away with. The new trick is to simply maintain a strongly undervalued exchange rate. For example, the Yuan is around 7.81 per dollar. On a PPP basis, the rate would be roughly 1.9 per dollar. This implies that the Yuan is 75% undervalued. This is an exaggeration because poor countries generally have market exchange rates lower than PPP parity.
Typically a country at China's level of development might value the Yuan 50% below PPP parity. This means that that Yuan should be 3.8 per dollar or more than 100% above the current exchange rate. Effectively China is imposing a 100% tariff on American imports and paying a 100% subsidy to China's exporters. Nice trick if you can get away with it.
So far the US has done nothing to repel this attack on the viability of our economy. The reasons are many fold including the widespread prevalence of radical free trade ideology. Of course, economic interests play a role as well. China has shrewdly bribed much of the elite economic class (investment bankers) to maintain the status quo (see Brad Setser's comments on this subject). More broadly, China has sold corporate America on a general strategy of "move your factories here, we will provide cheap labor, and then provide debt to consumers to buy the stuff they can no longer afford".
A fascinating point is that Japan never tried either approach. American financial institutions were kept at arms length (to say the least) as Japan boomed in the 1960s, 70s, and 80s. American corporations never seriously thought they could move their production operations to Japan and profit from the switch (Nike was an exception). As a consequence, American corporations regarded Japan, Inc. as a threat, not an opportunity for profit. China has been far more intelligent about this.
Of course, there are counterarguments. Without China's (and the other neo-mercantilists) lavish purchases of US debt, US interest rates would be considerably higher. The housing bubble would never have happened. Imports would be more expensive and some domestic products would sell for higher prices because of greater foreign demand.
Still, the US would be globally solvent and economically stable. The same can not be said for the status quo.
I would like to publish that letter. May I?
Let me point out that the Housing Bubble, which artificially inflates property taxes, hasn't been all that helpful to most people. Young couples can't get houses, older people can't find a place to live once they are forced out of the old family house. I do not think real estate bubbles are good for a real economy, although some speculators benefit greatly from them.
Otherwise I more or less agree. But NAFTA hasn't been all that useful either. There WAS a giant sucking sound. And one in the other direction too, of course. We have people who don't think they ought to have to mow lawns for a living, but their jobs making, say, store display furniture, have long gone away. The result could be imagined if it weren't all too plain.
This article brought back memories for me.
Some years ago I had a client who told me that -- as a young soldier -- he entered Vietnam in January 1975. I immediately remarked to him that we left Vietnam in April 1975. He said he knew that; he was on board the penultimate chopper out. He said I was the only person he had spoken to in twenty years who recalled the April "get the hell out of Saigon" date.
He told me he won his CIB in Vietnam before going on to other actions. I asked what those actions were. He would not provide any details about the actions except that they were all in the western hemisphere. When asked what he did he invariably answered, "I killed people and blew things up."
Some years ago I also had a colleague and friend named Quang Nguyen, who is without doubt the bravest individual I have ever known. He was a lieutenant in the Navy of the Republic of Vietnam. When the south fell, he was sent to a re-education camp. He escaped but was captured. After his capture, his education consisted of being confined to a 4x4x4 foot hole without toilet facilities and a rice ball and a liter of water a day for six months. This ruined his eyes. (When I met Quang, his vision was 20/120.) Nevetheless, he escaped again and walked to Thailand where he asked for asylum.
Quang Nguyen never expressed any anger about the US betrayal of South Vietnam nor about his treatment at the hands of his NVA captors. Once relations thawed, he entered into contact with the son of General Giap to buy garbage collection trucks from the US.
My other contacts with the lessons of the Vietnam War were direct and personal.
In the second week of UPT in 1981, my class was herded into the "Big Blue Bedroom" (the base theater) for a lecture. The lecture took 2 minutes from start to finish. The gist of it was you are training to be hired assassins; politicians are our masters; they will use us badly and never thank us; but we will do our goddammed best to accomplish any mission they set us and we will die trying; if you don't like those terms, you can resign now and the Air Force will release you from your contract obligations; but if you stay every man in blue will be your brother and he will die for you if the need arises. No one left.
During my Air Force career, I was indoctrinated (never officially) against McNamara-ism. In truth, I was taught to hate Robert MacNamara. The line went something like this: We are the United States Air Force; we are not GM; we don't make cars; we defend a country; no one asks an auto assembly worker to give his life as part of his job; we do; GM needs managers; we need leaders.
I had many military friends from the other services including the Coast Guard. I learned from every one of them that the military never forgets the lessons of history (I had a spirited discussion with a friend who -- as a Coast Guard commander -- had sat on the board that recommended court martial for Commander Eustis of the USCG Vigilant vis-a-vis the Simas Kudirka incident. He was opposed to the summary cashiering meted out by President Ford. I pointed out that the precedent came from 1799 when President John Adams cashiered Captain Philips for permitting the Royal Navy to impress men from his command. My Coast Guard friend was very familiar with the reference and pointed out salient differences. We argued this point for hours in the Vandenberg AFB O club.) I also learned that the memories of our masters extended back no further than the last election.
Legionnaires say "The Legion is my country." My experience was that this is no less true for those who serve in the American armed forces. I read J Glenn Gray's The Warriors in college; my military career confirmed Dr Gray's observations. At least for me.
Soldiers will not get to make the decision to stay in or to leave Iraq. But soldiers will remember either way.

Subject: Nasa question and empire
I read in Wired magazine a small article (I'm not quite sure how it passed editorial standards) decrying NASA's current priorities of manned space flight while cutting earth science (i.e., polar satellites for global warming studies) and unmanned exploration.
You follow space news more closely than I do ... do you know anything about what he's talking about? I ask, because I suspect that -- to the extent these are real developments -- your viewpoint on them may be substantially different than is.
Also, I am following your Republic Vs. Empire discussion, and I agree with you, that we have to be one or the other but not both.
And I would choose Empire.
Well, not really choose because I like the idea of no entangling alliances and limited government et al. But I simply don't see how such a thing is possible or even feasible today. For two reasons:
1) Nature abhors a vacuum. Thanks to technology, it is possible for one nation or combination of nations (a la the codo) to dominate the world. Given the drive and fanaticism of ambitious men in whatever Worthy Cause they aspire to, it is certain that this will be attempted. One faction will be defeated only to have another take it's place. And another and another and another.
If we choose Republic, it will require a certain amount of disengagement and isolation from the world -- we will lose our ability to influence events in the rest of the world. By default, those events will be influenced by other powers in the world. Eventually one power, or combination of powers, will arise.
I am certain that this power will be hostile to the United States. For the very reason you outlined in "Mote in God's Eye" -- we possess the capability to harm them, if not the intention. I have no doubt that those ruthless enough to take power will similarly not be concerned with any scruples about attacking without a good cause.
The United States can no longer afford the isolation it's Fathers intended for it, because our oceans no longer provide security against nuclear missiles or terrorists with fancy weapons. We are now, IMO, in the position of a continental power such as France was on Europe, if you think of "Europe" as being the entire planet.
There is simply no way such a monstrosity -- which will ALWAYS possess overseas interest, cutting off all our trade links overseas so that we have no interests overseas to fight for -- can coexist peacefully with other great powers. Even if we are absolutely still, our very existence will disturb and threaten theirs.
We must dominate, or be dominated.
We must step up to the plate and establish Empire, or go back into ourselves and take our position in someone else's Empire. There simply are no other alternatives that I can see.
I have seen the Iranians and the Russians and the Chinese and all the other contenders. If Empire is coming -- and I believe it is, in a few generations -- then better us then them.
That means, of course, that the Republic we both know and love will vanish, like Athenian Democracy or the Roman Republic. A terrible day. But the alternative will ALSO end the Republic, as I am certain other nations will not simply leave us alone.
"All we want is to be left alone" was the slogan of only one political figure in American history I remember, and his example is not one I would wish to follow.
2) Believe it or not, the educated classes of America ARE patriotic, but if they are anything like me -- and I was born in 1971, educated entirely in public schools -- their patriotism is to World Empire, not to the United States.
I wasn't ever told this directly, of course. But the thrust of movies and of games and of the sci-fi I watched was that loyalty to the United Nations superseded loyalty to the US the way loyalty to the US supersedes loyalty to Virginia. *I* believed this quite firmly until I left college.
So, we have a whole generation raised on "Star Trek" and similar stories, implanted firmly with the idea of Man as being a single political entity. Factor in to that continuous news stories from Darfur and Rwanda, encouraging the Great And The Good to go out and save the unwashed masses from themselves.
Note also that no one has raised a peep about our actions in Kosovo or Afghanistan. That's because, in a mind the way *I* was brought up, action by Humanity is moral and good, while action taken in the interest of the United States is lesser, common. The way I was brought up, I would view it much as we might today view Virginia invading Venezuela ... maybe a good idea or maybe not, but not something to do alone.
The reason is simple: In the educated class ... at least the part I was brought up in ... global government is the new Manifest Destiny. It is the idea that drives and energizes, as the United States does not.
The bottom line is that two generations of education have prepared the way for the US to be a global empire, and prepared the educated classes to do that very thing. And if we don't, we're sure to be dominated by someone else being driven by the same pressures.
We can't afford the luxury of Republic any longer.
The choice is: Rule, or Die.
The only way I can see to preserve a Republic is exactly the one outlined in your book -- for freedom loving individuals to take ship and set out to found a new society on the frontier. And the sooner, the better, I'd say. So get busy and invent the Alderson drive! As far as I can see, we're a few decades behind your schedule on that :)
There has always been an anti-manned space movement. My one time physics professor James Van Allen was quite vocal in opposition to wasting money on manned space. He wanted more planetary probes.
The two are mutually exclusive only because we have sunk a trillion dollars in an overseas war that we did not need to fight.
Which may be relevant to your second point. Rule or Die is not the lesson I take from history. The Venetian Republic sought neither and lasted a long time. Byzantium gave up the notion of world domination and managed to survie a very long time, indeed being brought down more by Western blind greed than by Muslim ability. Of course both Venice and Byzantium had strong military forces. The Venetian Arsenal was famed for being able to turn out a warship in a day.
I have certainly objected to our action in Kosovo. I have compared it to France bombing Washington because the United States refuses to turn over San Diego to Mexico. If you protest there is an Albanian majority in Kosovo I can point out that it got there by illegal immigration; Serbia did not invite Albanians (whom they consider collaborators with the Turks) into their most sacred province.
Global Government is I think a chimera. It is not possible, and those who seek it will waste their substance and break their hearts. I say this as a one time officer of several world government organizations which I fondly supported in my younger days.
If we are destined to become a global empire we had better learn a lot more about how to behave as an empire. I guarantee you that naive Jacobinism -- whether sincere or as my friend Cochran believes, feigned -- is not going to make for good imperial government.
Real empire is realistic. Real empire uses puppet kings and foreign troops, constabulary and occupation forces, keeping control of the puppets through Legions, and controlling the Legions through Praetorians. How the Praetorians are to be controlled is another matter. Quis custodiet and all that.
It may be that we cannot have a Republic, but it is no luxury. Republics are cheap, with self government, and wealthy citizens who do not work for government and do not seek rent and pensions. We may no longer have enough inhabitants well enough educated to be citizens of a Republic; in which case we will have empire. We will get it good and hard.
As to star drives, I would settle for the moment for a drive that will make asteroid settlements possible. After Inferno and Mamelukes that is probably my next story.

Subject: Comcast/Adelphia/RoadRunner e-mail
If I recall correctly, your home was on Adelphia cable and should now be TimeWarner/RoadRunner. I do not know if you receive any mail on those systems or if all is sent via your domain host. If you get some to a ca.rr.com address, you might want to glance at the headers.
This week, I have noticed a major delay in e-mail from someone in Colorado on a Comcast system that stayed Comcast to one of my RoadRunner addresses that used to be a Comcast address. Looking at old headers, the delays have began on Nov. 28 but were only an hour at that time.
On Thursday we did some tests--one to a mac.com account took 19 seconds and one to this old compuserve.com address took 14 seconds. He tried sending to a Yahoo account of his with no delay.
The Comcast to RR messages are getting delayed between 1 and 12 HOURS at the gateway between those systems. There are different Comcast and RR servers involved in these exchanges but over 3 days and over 40 messages, the quickest was about 1 hour. Most were at high end of delay range. I have sent some headers to RoadRunner and my friend is going to send some to Comcast.
FWIW--all of my mail actually ends up a group of servers named edge7.adelphia.net, edge8 and edge9--all of which stamp time as EST so are likely on east coast. I am in Costa Mesa, California and my mail software is pointed at "pop-server.ca.rr.com".
My guess is that all the forwarding of mail including spam sent to previous addresses of customers who have switched domains may be part of the problem.
I am NOT seeing any delays from systems other than Comcast to my RR address.
Thanks. Just now we're down at the beach house and we are not seeing any problems at all here. We are on Time Warner cable here.

Subject: There's a Hole
I need to pick a small error on the pipe through the center of the earth posting by Jim.
Item 2. There is no need for a comment on momentum as it is not forcing anything if you don't know the size of the pipe etc. There is a net force at bottom hole, the center of the earth, and that needs balancing by a similar column of water on the other side. This requires no momentum consideration, it is an energy balance.
Item 3. If we are talking about free fall in a vacuum, that is one thing, but lets consider a real pipe and the issue is somewhat different and calculating time and velocity is meaningless. Remember for instance you have to pump the air out of the other end, and it is a closed system so there are mass, viscosity, and wall friction considerations. Engineers have to think about such things, maybe physicists don't. Then again, we wouldn't want to ignore the tangential velocity component and how the energy is converted into pressure etc.
4. Heat transfer etc. is kind of cute but imagine the hoop stress on the pipe. Please don't mention stuff like this as it leads people to believe that practical engineering considerations have been considered and are soluble.
And Dr. Jim responds:
Item 2: I was considering the context of an open hole which was drilled from an unspecified point within CONUS to the antipodes in the Indian Ocean, presumably initially unfilled, and with (following Mr. Hellewell's original presumptions) many of the engineering considerations ignored. I agree that final equilibrium is defined by the energy balance (that was in fact the basis my first response) but the initial dynamic situation of water flowing into the pipe does require consideration of fluid momentum for a detailed answer. I will note that my "first order" answer did not consider any fluid dynamic considerations but was a point approximation for the fluid surface, and implicltiy assumed more or less laminar flow, also a poor approximation to the stated problem.
Item 3: I concur, and acknowledge that those considerations were ignored by my first order answer.
Item 4: I'll admit that I didn't give much consideration to hoop stress until after I penned the initial answer, but that if someone were to realistically consider the problem there are a number of additional factors as well -- hoop stresses, thermal stresses (temperature gradients sufficient to allow significant differential rates of thermal expansion), compression by the overlying magma (and you're certainly moving beyond my knowledge of geophysics -- and elasticity of non-newtonian materials) to consider how closely the inner core can be approximated by a hydrostatic sphere at an equilibrium pressure which varies with radius, much less the effects of the outer core and the mantle. The material suggestion was, frankly, intended to be a "cute" idea rather than a serious solution for this application; that said, there aren't many other material candidates that would stand a better chance of working. The engineering magnitude is on the scale of conventional "beanstocks" -- 13,000 km long -- and the engineering problems are of evern greater mangitude because of the thermomechanical environment (even assuming, of course, that the tunnel boring machine can survive past the mid-mantle). Therefore the actual thickness of a pipe built from even the strongest conventional materials would be of the order of 10 km.
Subject: hole through the earth's centre
The obvious solution to the "hole through the centre of the earth" problem is to line it with unobtanium. This has infinite strength and given that the correct grade is selected, infinite thermal resistance. So, the pipe would fill and the level in the two ends would only fluctuate slightly due to the relative variation in atmospheric pressure at those ends. To critics who say that this solution is fantastical, I reply that as soon as they have drilled the hole I will provide the lining at no cost.

Study: More Internet Journalists Jailed
By RUKMINI CALLIMACHI Associated Press Writer
NEW YORK (AP) -- When Iranian journalist Mojtaba Saminejad was sentenced to two years in prison for insulting the country's Supreme Leader, it was not for an article that appeared in a newspaper. His offending story was posted on his personal Web blog.
Nearly one-third of journalists now serving time in prisons around the world published their work on the Internet, the second-largest category behind print journalists, the Committee to Protect Journalists said in an analysis released Thursday.
Subject: Crazy years?
As this grows more weird with every passing day I remember Robert Heinlein and his Crazy Years period where people under high population pressure acted in self destructive ways like Lemmings. Now was he really a visionary and prophet or was his insight accidental. I feel that most good SF writers, yourself included are very good observers of the world around them and able to extrapolate from what they see happening around them what will come if things do not change. Now will we have a theocracy of the right as Mr. Heinlein predicted or one of the left (1984 style) as many others have predicted.
I await what will happen prepared for the worst by the writers with long views that I have read for the last 50 some years while hoping for better. I do not expect to see better because it seems as time passes that good SF writers are also very good predictive prophets of what is to come if people do not mend their ways.

Subject: sexual harassment
Words fail me.
IMHO, unless either Ahmadinejad or Kim become impatient for some reason, I think they'll stay low-key for two years, and hope for Ms. Rodham's election, or the election of someone to her "left." Which is why I've commented about saving for an anti-radiation suit to visit Jerusalem in late January 2009.
If it comes to that, I think I would have to hope for Ms. Rodham -- the Clinton's have always been practical politicians, and I think that she, at least, would realize (maybe even more so than her husband) that an existential threat to the US must be confronted and cannot be talked through.
The essay is well worth reading. I am not at all sure that we will wake up and deal with Radical Islam.
You will find more of Joanne Dow's "Daily Diatribes" at her page. Some have said they see no reason for me to publish those. I do it because it seems to be true: the only thing now to debate is the color of the surrender flag. Joanne is an intelligent feminist and one of the few whose views I respect. Note I said respect; which is not necessarily agreement. It is worth documenting the matter that is before us. No, not all Muslims are monsters, and "Islamo-Fascism" is both and ugly and inaccurate -- actually rather ludicrous -- term.
But if 10% of a billion people believe and behave in this way, then they are a danger to our existence; and 10% is no bad estimate of the number of Muslims who hate us enough to wish us ill and cooperate with the 1% who actively seek to harm us and the .1% who will make sacrifices to do so. And .1% of a billion is still a million. Suppose that latter number is actually only .01%?
It makes sense to track what the crazies are doing if they really want to kill us. In any event, there are three more diatribes.
Deep Hole Coda
This problem just grows and grows...my final answer should be amended to note that the size estimate (which was a swag based on the comparative numbers for steel beanstalks) assumes an integral cooling system with enough heat flow capacity to prevent melting of the pipe surface and enough structural integrity to avoid being collapsed by the pressures at the center of the earth.
I've double checked some numbers on the Earth's core at http://en.wikipedia.org/wiki/Earth%27s_core <http://www.wikipedia.org> (something I probably should have done before sticking my neck out on this). I was apparently remembering core temperatures in Celsius as being in Fahrenheit; the core is about 3000 degrees F hotter than I recalled (9000 degrees F), and is kept solid due to hydrostatic pressures on the order of 3 million atmospheres. 6000 degrees F is close enough to the melting point of TC (5198 F) that cooling could plausibly work to maintain it; the metal could be cooled against 9000 F gas flows, but I doubt it could be cooled against immersion in a liquid (any liquid!) at those temperatures, and the pressures would certainly collapse any cooling pores. (I wonder if there is any value in trying to engineer a cooling system where the pressurized superheated coolant can balance the compressive hoop stresses, killing both birds with one stone).
So cite my faulty memory, which has probably let this be carried on too long. Or at least the discussion of materials for the pipe, plausible and otherwise.
I'll write again when I figure out how to manufacture arenak.
Before heading straight down 4,000 miles for R&R, please leaf through some back issues of the Journal of Geophysical Research.
The fashionable neighborhoods end about 3000 miles underfoot, at the heliopause . Heliopause ? What's a heliopause doing underground ? Well, it now seems likely that the core is somewaht hotter than 5,800 Kelvin m so on the way there, the countryside's incandescence will surpass that of the apparent surface of the sun.
A good pair of Okleys is therefore advised, but as to the question of what to wear that won't get crushed by the three megabars and change at the core , a diamond tank top won't do- diamond gets woozy at a megabar and a half , and will fold into Lonsdaleite- the hexagonal close packed allomorph of carbon at around two- at room temperature . At 6000 Kelvins or thereabouts , it's all going to be squishy, albeit very stiff- the viscosity of stuff at several megabars runs to ten to the twentysomething Poise . One of these centuries they will push the periodic table on out to the next row down, where eka-tantalum carbide or eka-thoria may afford melting points closer to ambient core temperature- but don't count on it.
