Slashback: Hilbert's, Transgenic, Silicon 214
Still an acorn at this point. Jose Nazario writes with a correction to my recent post claiming that OpenBSD had gained a "fuzzy" user-profiling IDS. Jose writes: "It is NOT in tree. it is a privately developed research project. It is not an official project."
And Yes, the Apple I schematics were available, too. In response to the recent article about the freely available chip design from opencores.org implemented by Flextronics, Henry Keultjes offers a reminder that this is not the first time chip whose internals have been open for inspection:
"Happened quite some time ago with PowerPC. That's the essence of Microsoft's deal with IBM because without that Open Architecture Microsoft would have had to buy a lot more than it did. This for example is used in a roughly $150 French set-top box that has USB and, according to a friend in the UK who has tried that, runs just fine as a PC with the attached USB HDD, KB and rodent."
Could Wayne Inouye sell you an eMachine? After reading many pointed comments in the story about eMachine's Athlon offerings, arrasmith writes "To add to the topic of AMD64 eMachines and the launch of "I hate eMachine" posts I'll throw out why you should buy one.
eMachines are the number-3 seller of computers, only behind Dell and HP. If you are wondering about how that happened, you need to read about the new CEO.
Wayne Inouye has had some articles published about him in Business Week and Forbes. Great articles on how you can sell good computers at reasonable prices. And if you are wondering why eMachines is selling an AMD64 system read the Business Week article."
OK, as long as you buy it from us. Alien54 writes "As reported in the most recent Spyware Info Newsletter, Dell seems to have listened to the criticism handed to them last week, after their decision to forbid tech support persons from providing assistance to spyware-infected customers became public knowledge. They have partnered with PestPatrol, Inc. to sell Pest Patrol's spyware removal software to Dell customers. It is interesting to note that Dell does not recommend any freeware or shareware product because 'we cannot test these open source utilities reliably.' Which is simply silly, of course."
Utah may not be Utopia after all. brysnot writes "The Salt Lake Tribune reports that the Utopia project, which plans to run fiber to every home in Utah, has miscalculated its 2003 budget and now needs each member cities to come up with an additional $250,000. Also reported is that 'Its largest member, Salt Lake City, is uncertain whether to provide financial backing to guarantee payment of the principal and interest on the bonds the project needs -- a development that could force the project to be scaled back.'"
Writes Lighthop "The best way to overcome Qwest's vast resources and well orchestrated opposition is for citizens and business owners to speak out and let their city council members know we support them in approving UTOPIA's funding. We have to be visible and give them some political cover.
The 18 UTOPIA member cities are Brigham City, Cedar City, Cedar Hills, Centerville, Layton, Lindon, Midvale, Murray, Orem, Payson, Perry, Riverton, Roy, Salt Lake City, South Jordan, Taylorsville, Tremonton and West Valley."
Hilbert's 16th is still a problem. commodoresloat writes "The work of Elin Oxenhielm, the 22-year old Swedish student who apparently solved part of the 16th Hilbert problem, is coming under heavy fire from some prominent mathematicians, including her own adviser, who said the work contained "serious mistakes, which I think any educated mathematician can easily see." Here's an article in English. Oxenhielm responded to the criticism by saying that the journal that accepted her work, which now owns the copyright, is responsible for any errors. More information on this weblog."
Periscope is up, showdown commences. McSpew writes "The Register states that Microsoft's patents on the FAT filesystem may be subject to new scrutiny, thanks to their announced plan to collect royalties from media and CE manufacturers. The Public Patent Foundation is behind the effort to get the USPTO to start from scratch with Microsoft's FAT patents."
FDA gives GM fish sales the eerie green light. fishfishfish writes "The US Food and Drug Administration (FDA) Tuesday released a statement saying that it will not be stopping the sale of transgenic Zebra danios in the USA. The move could allow fish retailers in any U.S. state to sell the fish. Apart from California, where Arnie has banned them..."

Chances are probably not as bad as you might think. Two non-fugly math girls, lonely for a little love yet repulsed by the animate male lumps of lard and sweat surrounding them. Both so lonely, so sad. Trying to concentrate on their work. Young student huddled close together with advisor, going over a math problem. Then it happens! Zhou's hair brushes ever so lightly against Oxenheilm's cheek. They pull back from each other in surprise. They both felt it. And in that moment, their lives changed forever. It was unavoidable. It was their destiny. Their professional composure decays exponentially fast as they both realize the inexorable truth. They are going to have sex and there is nothing either of them can do to stop it. Is this attraction stable? Does it matter anymore?
Clothes are pulled off each other in an optimal fashion. Each woman studies the continuous curvature of the other's body. Fingers trace the inflexion points, the saddle points, the contours, and then, utimately, the poles. Their fingers now slick with the complex residue of the other, their heart beats begin to constructively interfere with each other. The intensity of one heart increased by the feedback from the other. So wrong. So dangerous. So good.
Groups give way to gropes. Rings give way to rimjobs. Fields give way to fondles. Their fingers, so skilled at manipulating mathematical equations, now find a use in manipulating each other's boundary layers. Both women writhe and squirm in unison until they are epsilon away from a mutual orgasm (epsilon -> 0 quadratically fast).
And then it's over. No more theorems, lemmas, corrolaries or proofs. The two young women lie on the floor knowing that their relationship has changed forever. Without a word they clothe themselves and the impressionable young student leaves the office. Never again will they discuss this incident. This will be an isolated singularity hidden for all time in the vast infiniteness of time.

The second part of Hilbert's 16th problem deals with limit cycles, the way things will go on eventually in dynamical systems if they are not disturbed externally. The subproblem 2/3 of this problem (it's the indexing that makes math complicated..) asks if there exists an upper bound on the number of different limit cycles one can have in the system.
Oxenhielm attacks the problem by considering first a special case called the Lienard equation and approximating its solution by harmonic oscillation. The proof begins: "Noticing that the state variable x of the Lienard equation (1) behaves approximately like a sine function in simulations (see Fig.1),we assume -- in order to make a good approximation of x -- that both state variables are dominated by a harmonic term
Now, to my engineer's eyes, the functions in Fig.1 seem more like triangular waves, with definitely more than one single frequency component. Yet the accuracy of the approximation has not been considered at all in the paper. Also, 'proof by looking at results of simulations' is not really valid if you don't have any other evidence.
Another bad part is on page 6, where it is claimed that "Note that the method of describing functions may be used in a similar manner as in the proof above,to find the upper bounds for the Hilbert number in any planar polynomial vectorfield. Thus, it is possible to completely solve the second part of Hilbert's 16th problem by using this approach."
Wait a minute, how did that happen? What if the harmonic approximation fails on other than Lienard equations? It might just work, I have no idea, but this assertment hardly proves the fact.
Note however that this is very different from Andrew Wiles' proof of the Fermat conjencture. While very few people in the world could understand the odd-hundred pages of Wiles' proof, Oxenhielm's paper is just eight pages of much more accessible mathematics.
