Gordon's Tech: Parallels to VMware - my experienceWindows 2000 SP4 runs Office 2003 and most business apps without any problems -- that's all I need. I have two unused Win2K licenses, so it costs me nothing. It's much more compact than XP, it demands fewer CPU resources, and it runs happily in only 256MB of memory.
As part of my move from 10.4.11 to 10.5.3 I switched from Parallels (Windows 2000 VM running Office 2003 and MindManager to VMWare Fusion (updated 5/30 for 10.5.3). Here's how it went...
Outlook is the only email application I know of with the absolutely critical feature that Gmail most urgently needs.
In Outlook I can edit the subject line of messages I've received*. (You can edit the body and attachments of received email as well; that's very nice but not essential.)
Gmail can't.
Neither can other email packages, but the problem is more severe in Gmail because it threads conversations by subject line. Since most humans are still living in the 20th century they don't use intelligent subject lines; important messages get lost in the same-subject-line thread. To add insult to injury, Google's threading model discourages intelligent subject lines.
21st century people know subject lines are critically important. We don't do folders, we do search. The initial presentation for a search result always includes the subject line -- it tells us what's important.
(Digression. I do find it a bit odd that Googlers evidently don't do search.)
If all my correspondents were 21st century I wouldn't have as dire a need to edit the subject lines of their messages, but even so what I consider important may differ from their opinion. I'd still like to be able to edit their subject line on occasion. (Note: Emily, you do fabulous subject lines. I'd say that even if you weren't my wife.)
Sure, this breaks the evidence chain of email. I don't give a damn. I have zero interest in preserving the email I receive in some kind of pristine state. When I archive it I'm doing it for my own benefit, not for anyone else's benefit.
Google, you can fix this. It will help break your compulsion to thread conversations by string matching the subject line (which also breaks Google Groups, but that's another story).
* It's amazing how many people don't know this. Just click on the subject line of an email you're received and type. Shocked?
A year or two ago I paid a modest fee for extra Picasa web album storage. The storage pool is shared with my Gmail account.
I realized today that even though I add images and my email volume grows, I don't seem to be running out of space.
Basically, Google is adding to my allotment at roughly the rate I'm consuming it. The current number is:
6.5 GB (39%) of 16.6 GB
It's been about 35-40% for at least a year. For my current usage rates Google's storage allotment is essentially unlimited.
The odd thing is that we've come to take this for granted, so much that nobody comments about it any more.
I am fascinated by the big changes that, for the most part, we don't recognize ...
I'm putting together my plan and resources to prepare for the 2008 Family Medicine re-certification exams. These exams used to be pretty stress free, but that was back when I actually did family medicine!
I'm surprised how scattered the resources are on this topic. I'll list what I've found, and update this post over the next two months. I'm restricting my list to items available through the AAFP, ABFM (board), or "free" (typically pharma or ad supported). Most of these links work only for AAFP members or recert exam registrants.
For my commute I have a backlog of Audio CME to add to my iPod, but iTunes also has a pretty good listing (though as badly organized as every other Apple item list I've seen). I've also found a UCSF newsletter (pdf) with an article on medical podcasts.

Update 8/15/08:
I've long had an information-geek's admiration for the printed version of Monthly Prescribing Reference. Despite its evil ad-funded roots, there's a real genius to the density and layout of the content, refined by generations of customer feedback. It also has the virtue (and sin) of being always topical and exceedingly brief.The updater for OS X Leopard is over 1/2 GB in size.
MacInTouch: timely news and tips about the Apple Macintosh
Apple today posted Mac OS X 10.5.3, the latest in its series of bug and security patch collections for "Leopard". The 10.5.3 Combo update is 536 MBytes in size.
I downloaded it in under 10 minutes.
A 1/2 GB isn't what it used to be.
Yes, 10.5.0 was a very buggy initial release.
It's been about six years since I've updated my personal medical notes reference page. These are references for a family physician, not for a patient.
Revised: May 2008.
Most of the books link to MD Consult which I access through my UMN account. Sadly, even the AFP references are now access controlled. MD Consult, Harrison's Online, TheraDoc and more are freely available, as of May 2008, for persons able to register with MerckMedicus. Note that the MerckMedicus web page has trouble with modern browsers and especially with tabs.
Yes, it's board review time.
A six year editorial life cycle means one or two links went bad.
Ok, about half of them.
Here are the sorts of things that survived:
Here are the things that went away
Within the US the survivors have a business model of some sort. Nobody seems to want to touch procedures any more -- I wonder if that's just my sample or if there are more litigation fears. Outside of the US things are more persistent. Even many of the surviving sites don't handle bad links very well.
I'll have to try to do another recap six years from now ...
Lessons from Microsoft SharePointEverything is laid out in Sharepoint for observant eyes to see. There's nothing in this design that outside the everyday functions Google implements now. Sure, there may be a few software patents around Microsoft's work (there should be), but that's what lawyers are for. I suspect most of it has prior art, and the rest can be worked around or fought in court. (It's the combination that's clever.)
...I'm told the implementation is more peculiar than this, but to a first approximation SharePoint can be considered as a thin client toolkit for creating and manipulating SQLServer tables. Microsoft Access will link to them, and read and write to the linked tables. You can do some simple lookups from one table to anohter (scope is site limited). You can revise and extend tables quite readily, building on your data model as needed. There's a quite good web GUI for user views of the data, and a somewhat powerful but semi-broken Excel like datasheet view for quick editing.
Whereas the document management system feels like it was hurled out a window to meet a deadline, the list facilities feel like someone thought very hard about how they might work...

Long Now Essays - W. Daniel Hillis - Richard Feynman and The Connection MachineI'm struck that Feynman was good at giving up on problems where he wasn't making progress. That's something most of us, albeit on a far more modest scale, find hard to do. We run the risk of pouring efforts down a project with a limited chance of success. Feynman knew there were always other interesting problems, problems that were likely to be easier to solve.
... Richard's interest in computing went back to his days at Los Alamos, where he supervised the "computers," that is, the people who operated the mechanical calculators. There he was instrumental in setting up some of the first plug-programmable tabulating machines for physical simulation. His interest in the field was heightened in the late 1970's when his son, Carl, began studying computers at MIT...
...We were arguing about what the name of the company should be when Richard walked in, saluted, and said, "Richard Feynman reporting for duty. OK, boss, what's my assignment?" The assembled group of not-quite-graduated MIT students was astounded.
After a hurried private discussion ("I don't know, you hired him..."), we informed Richard that his assignment would be to advise on the application of parallel processing to scientific problems.
"That sounds like a bunch of baloney," he said. "Give me something real to do."
So we sent him out to buy some office supplies. While he was gone, we decided that the part of the machine that we were most worried about was the router that delivered messages from one processor to another. We were not sure that our design was going to work. When Richard returned from buying pencils, we gave him the assignment of analyzing the router...
... During those first few months, Richard began studying the router circuit diagrams as if they were objects of nature. He was willing to listen to explanations of how and why things worked, but fundamentally he preferred to figure out everything himself by simulating the action of each of the circuits with pencil and paper.
...Richard did a remarkable job of focusing on his "assignment," stopping only occasionally to help wire the computer room, set up the machine shop, shake hands with the investors, install the telephones, and cheerfully remind us of how crazy we all were...
...I had never managed a large group before and I was clearly in over my head. Richard volunteered to help out. "We've got to get these guys organized," he told me. "Let me tell you how we did it at Los Alamos."
Every great man that I have known has had a certain time and place in their life that they use as a reference point; a time when things worked as they were supposed to and great things were accomplished. For Richard, that time was at Los Alamos during the Manhattan Project. Whenever things got "cockeyed," Richard would look back and try to understand how now was different than then. Using this approach, Richard decided we should pick an expert in each area of importance in the machine, such as software or packaging or electronics, to become the "group leader" in this area, analogous to the group leaders at Los Alamos.
Part Two of Feynman's "Let's Get Organized" campaign was that we should begin a regular seminar series of invited speakers who might have interesting things to do with our machine. Richard's idea was that we should concentrate on people with new applications, because they would be less conservative about what kind of computer they would use. For our first seminar he invited John Hopfield, a friend of his from CalTech, to give us a talk on his scheme for building neural networks...
... Feynman figured out the details of how to use one processor to simulate each of Hopfield's neurons, with the strength of the connections represented as numbers in the processors' memory. Because of the parallel nature of Hopfield's algorithm, all of the processors could be used concurrently with 100\% efficiency, so the Connection Machine would be hundreds of times faster than any conventional computer...
... Feynman worked out the program for computing Hopfield's network on the Connection Machine in some detail. The part that he was proudest of was the subroutine for computing logarithms...
... Concentrating on the algorithm for a basic arithmetic operation was typical of Richard's approach. He loved the details. In studying the router, he paid attention to the action of each individual gate and in writing a program he insisted on understanding the implementation of every instruction. He distrusted abstractions that could not be directly related to the facts...
... To find out how well this would work in practice, Feynman had to write a computer program for QCD. Since the only computer language Richard was really familiar with was Basic, he made up a parallel version of Basic in which he wrote the program and then simulated it by hand to estimate how fast it would run on the Connection Machine...
... By the end of that summer of 1983, Richard had completed his analysis of the behavior of the router, and much to our surprise and amusement, he presented his answer in the form of a set of partial differential equations. To a physicist this may seem natural, but to a computer designer, treating a set of boolean circuits as a continuous, differentiable system is a bit strange. Feynman's router equations were in terms of variables representing continuous quantities such as "the average number of 1 bits in a message address." I was much more accustomed to seeing analysis in terms of inductive proof and case analysis than taking the derivative of "the number of 1's" with respect to time. Our discrete analysis said we needed seven buffers per chip; Feynman's equations suggested that we only needed five....
... The first program run on the machine in April of 1985 was Conway's game of Life.
... The notion of cellular automata goes back to von Neumann and Ulam, whom Feynman had known at Los Alamos. Richard's recent interest in the subject was motivated by his friends Ed Fredkin and Stephen Wolfram, both of whom were fascinated by cellular automata models of physics...
... we were having a lot of trouble explaining to people what we were doing with cellular automata. Eyes tended to glaze over when we started talking about state transition diagrams and finite state machines. Finally Feynman told us to explain it like this,
"We have noticed in nature that the behavior of a fluid depends very little on the nature of the individual particles in that fluid. For example, the flow of sand is very similar to the flow of water or the flow of a pile of ball bearings. We have therefore taken advantage of this fact to invent a type of imaginary particle that is especially simple for us to simulate. This particle is a perfect ball bearing that can move at a single speed in one of six directions. The flow of these particles on a large enough scale is very similar to the flow of natural fluids."
This was a typical Richard Feynman explanation. On the one hand, it infuriated the experts who had worked on the problem because it neglected to even mention all of the clever problems that they had solved. On the other hand, it delighted the listeners since they could walk away from it with a real understanding of the phenomenon and how it was connected to physical reality.
We tried to take advantage of Richard's talent for clarity by getting him to critique the technical presentations that we made in our product introductions... Richard would give a sentence-by-sentence critique of the planned presentation. "Don't say `reflected acoustic wave.' Say [echo]." Or, "Forget all that `local minima' stuff. Just say there's a bubble caught in the crystal and you have to shake it out." Nothing made him angrier than making something simple sound complicated...
... as the machine and its successors went into commercial production, they were being used more and more for the kind of numerical simulation problems that Richard had pioneered ... Figuring out how to do these calculations on a parallel machine requires understanding of the details of the application, which was exactly the kind of thing that Richard loved to do.
For Richard, figuring out these problems was a kind of a game. He always started by asking very basic questions like, "What is the simplest example?" or "How can you tell if the answer is right?" He asked questions until he reduced the problem to some essential puzzle that he thought he would be able to solve. Then he would set to work, scribbling on a pad of paper and staring at the results. While he was in the middle of this kind of puzzle solving he was impossible to interrupt. "Don't bug me. I'm busy," he would say without even looking up. Eventually he would either decide the problem was too hard (in which case he lost interest), or he would find a solution (in which case he spent the next day or two explaining it to anyone who listened). In this way he worked on problems in database searches, geophysical modeling, protein folding, analyzing images, and reading insurance forms.
The last project that I worked on with Richard was in simulated evolution. I had written a program that simulated the evolution of populations of sexually reproducing creatures over hundreds of thousands of generations. The results were surprising in that the fitness of the population made progress in sudden leaps rather than by the expected steady improvement. The fossil record shows some evidence that real biological evolution might also exhibit such "punctuated equilibrium," so Richard and I decided to look more closely at why it happened. He was feeling ill by that time, so I went out and spent the week with him in Pasadena, and we worked out a model of evolution of finite populations based on the Fokker Planck equations. When I got back to Boston I went to the library and discovered a book by Kimura on the subject, and much to my disappointment, all of our "discoveries" were covered in the first few pages. When I called back and told Richard what I had found, he was elated. "Hey, we got it right!" he said. "Not bad for amateurs."
...Actually, I doubt that it was "progress" that most interested Richard. He was always searching for patterns, for connections, for a new way of looking at something, but I suspect his motivation was not so much to understand the world as it was to find new ideas to explain. The act of discovery was not complete for him until he had taught it to someone else...
A resurgence in nuclear plant development has three justifications:
All three seem plausible, so Italy and other European nations are building "fourth-generation" reactors...
Italy's nuclear move triggers chain reaction - Scotland on Sunday
... Once the most-scorned form of energy, the rehabilitation of nuclear power was underscored in January when John Hutton, Labour's Minister for Business, grouped it with "other low-carbon sources of energy" like biofuels....
... There is now a determination to tackle the issue head on throughout the continent. With nuclear plants taking up to 20 years from conception to becoming operational, European nations are now having to answer some very difficult questions. The dilemma of Italy, as the biggest importer of oil and gas, are the most pressing: there is no chance of reactivating sites or building new ones within the next five years.
... Enel, Italy's leading energy provider, announced this year that it would close its oil-fired power plants because the fuel had become too costly. Italians pay the highest energy prices in Europe. Enel has been building coal plants to fill the void left by oil. Coal plants are cheaper but create relatively high levels of carbon emissions.
Enel, which operates power plants in several European countries, already has at least one nuclear plant, in Bulgaria, and has been researching so-called fourth-generation nuclear reactors, which are intended to be safer and to minimise waste and the use of natural resources...
It makes sense to build more nuclear plants. It is unfortunate, however, that they're being built in very crowded nations. If we casually disregard technical issues with transporting power (ship metallic hydrogen? superconducting power lines?), and exclude the desire for national control, it would seem to make more sense to build them in remote areas of northern Canada, possible on the sites of existing Hydro facilities or together with large data centers.
Nuclear plants and data centers, after all, have a few things in common:
In addition there are many good reasons to keep nuclear plants far from human habitation. Canada is an obvious location given its relative political stability, proximity the US market, enormous swaths of minimally populated land, and technological capabilities. Heck, compared to the Alberta tar sand environmental holocaust nuclear power plants in the North are positively benign.
So will Google and Microsoft go into the nuclear power business? Will Canada's native peoples become the Saudis of the 21st century?
This should be interesting.

Clever Uses: Fix a Stripped Screw Hole with a Golf TeeUpdate 5/28/08: A generous commenter praises matchsticks for irregular holes -- along with lots of wood glue. I'd guess it would be best to match the wood bit to the hardness of the surrounding material, and of course one could creatively mix and match. The golf tees I used on the back gate are working very well, but they've only been there two days.
How-to blog DIY Life says a wooden golf tee and some wood glue is all you need to make that hole as good as new. Just slather the tee with glue and tap it into the offending hole until it's secure, let it dry, then cut off what's sticking out. If the stripped hole is too small, the post recommends flat toothpicks can do the trick, too.
