Re:Yes yes yes
You know where I can get a 1960's quality University of Chicago education and not end up in debt?
Germany, England, France, Switzerland etc.
And I'm not just bragging about our European system here. I mean seriously - go study to Europe, the tuition is a fraction (and I mean a tiny fraction) of what you'd pay in the US, the quality of the top universities is high and a foreign degree will look cool in your CV. A lot of the universities even offer curricula in English.

Single Correlation parameter?
The article keeps going on about a single correlation number. That's only true if there are 2 mortgages, and the copula is a bivariate normal distribution (see page 14 of the paper )
Real CDO's have more than 2 assets, so the correlation matrix used is key. This is a reason why prices can't be agreed for CDO's. Everyone uses different correlation matrices. Option pricing has a market because Black Scholes only has a volatility parameter to trade around. -
Release Notes
I was able to get in before it was fully slashdotted (it was crawling when there were only two posts here).
Here are some US mirrors:
CA ftp://mirrors.isc.org/pub/DragonFly/
TX ftp://mirror.evilprojects.net/pub/DragonFlyBSD/
VA ftp://ftp.theshell.com/pub/DragonFly/iso-images/And some EU ones:
UK ftp://ftp.as6911.net/pub/DragonFly/
Germany ftp://chlamydia.fs.ei.tum.de/pub/DragonFly/Here's the Release Notes:
Release Improvements* A new DVD ISO release image is now available, in addition to the CD release.
* The new DVD release has a full X environment ready-to-go and many packages pre-installed.
* A full pkgsrc tar is now available on the CD/DVD in /usr.
* Full sources tar now available on the DVD (kernel sources only on the CD), in /usr.
* The nrelease build now trivializes package selection for people creating customized releases.
* The installer is now able to create a HAMMER filesystem setup.Kernel changes

* HAMMER is now considered production-capable. Many bug fixes and other improvements have been made.
* It is now possible to boot from a HAMMER-only disk. No need for a single UFS partition for /boot. However, for production systems we still recommend a small UFS /boot followed by swap followed by one large HAMMER partition.
* Add HAMMER read support to the boot loader.
* Now uses per-mount kmalloc pools for bulk data structures, particularly for inodes and records.Hardware changes
* Add ACPI support module for IBM/Lenovo Thinkpad laptops (from FreeBSD).

* Add acpi_video(4) - a driver for ACPI video extensions (from FreeBSD).
* It is possible to power down PCI devices during -
Re:one proof engine
HOL is said to be usable, but doesn't have the same opportunities for name abuse, though 2001 fans could come up with a whole bunch of new ideas. Isabelle, however, would provide such opportunities, if you were to combine it with the package that started this thread. ACL2 is the least abusable name of all, so is quite useless.

Yet another research grant...
..and most of the challenges have little to do with math. Meanwhile, here's something which could lead to real progress in mathematics (From the Slashdot Firehose):
An anonymous reader writes:
"Cameron Freer, an instructor in pure mathematics at MIT, is working on an intriguing project called vdash.org (video from O'Reilly Ignite Boston 4): a math wiki which only allows true theorems to be added! Based on Isabelle, a free-software theorem prover, the wiki will state all of known mathematics in a machine-readable language and verify all theorems for correctness, thus providing a knowledge base for interactive proof assistants. In addition to its benefits for education and research, such a project could reveal undiscovered connections between fields of mathematics, thus advancing some fields with no further work being necessary."

Re:Where's my $200 laptop
I agree with the "used" approach.
I spent $100 on a deal for two used Compaq Armada M300 machines (PIII) and a docking station. They're small (barely bigger than an Eee PC in one dimension, because the screen is 4:3 aspect), light (magnesium shell), 1024x768 12" displays, run various version of Linux and PCMCIA wifi with no problems, and even run Windows 2000 fine (I haven't tried XP). What more do I really need for web browsing and e-mail? These things aren't for gaming or heavy-duty stuff anyway. The only downside has been the battery life and the cost of it: ~$100 more for replacement batteries that give only ~2.5hrs, because the batteries that came with the units were dead. Still, 2 laptops for the price of one EeePC ain't bad, and the form factor is fairly similar. Oh, and the wifi sticking out of the PCMCIA slot looks a bit ugly, but so what.

Research not limited to Japan
This is not exactly new research. The German project SIPBILD is aiming for the complete recognition of facial expressions, body language and gestures http://www.forsip.de/index.php?show=projekte_sipbild2&page=1&lang=en.
The project has been running for several years now and the last publications date back from 2006.
More information on the recognition of facial expressions can be found at the TU Munich under http://vision.in.tum.de/projects/mimic_recognition/.
I am really fascinated by the research but why the hell did it take so long to figure this one out? The problem seems obvious and the solution cannot be that hard... -

I can also tell you that the project is complete and utter crap, from a scientific perspective.

In general, the "science" is poorly-conceived and improperly controlled, and most of the "experiments" are methodologically flawed. I can't post my name here...it would be career suicide.

Re:Inline spellchecking needs work
Funnily enough the best for large stuff seems to be Outlook Express. Only that's basically unusable because it doesn't do quoting correctly and you have to manually edit the message (trying doing that when replying to a 500 line epic).

I think you're wrong
Or, at least you're wrong about modern programmable GPUs; you might have been right about the first generations of 3D cards.
See this paper for some examples which not only use the GPU simultaneously for graphics and number crunching, but which use the graphics to give real-time output of computational fluid results.
The only remaining problem I remember is that the bandwidth to current video cards is very asymmetric, which is fine for video games that just push a lot of data to the video card but not so good for numerical physics that also wants to ask for a lot of data back. I think at least one of the new PCI-Extended/Express/X/whatever standards is supposed to fix this. -

Re:Why has this taken so long?
Honestly, it's hard to believe that it took PHD "rocket scientists" to come to the conclusion that email is probably better interfaced as a forum. We've all known that for years.
Indeed: see gmane.org. (Which itself has a strong cultural inheritance from Gnus, the Emacs newsreader that lets you read mail and other things as though they were newsgroups.)
In the story, the supposed faults of electronic mail - that it is easy to view one message but hard to set it in context, to see who is saying what to whom - could be fixed or at least greatly reduced by proper quoting and attribution. If Microsoft changed Outlook and Outlook Express to make it easy and encouraged for users to do concise, non-Jeopardy quoting followed by a reply, rather than typing a few words then followed by masses of irrelevant autoappended gunk, they'd do the net a big favour.

Re:Bloatware
Expose is a feature of the OS you can't remove it, but you CAN turn it off. Safari is an app that includes a library (KHTML/WebKit) that a few other apps need in order to run - see SubEthaEdit. This will only get worse now that Safari, and it's libraries are included with the OS. Finder while an App separate from the OS, is not nearly as simple to get rid of as, say, iChat.

Re:I'll reserve judgement
Whenever you add or modify a file, WinFS adds the file's attributes to its indexes. The attributes stored are customizable...
I keep wondering whether this sytem will incorporate any of the ideas being formulated by Prof. Rudolf Bayer and his team. The first paper in this series probably best summarizes the ideas being generated here. There's some really cool stuff here. From the abstract:
With the new method, a single UB-tree can replace an arbitrary number of secondary indexes. For updates this means that only one UB-tree must be managed instead of several secondary indexes. This reduces runtime and storage requirements substantially. For queries and in particular range queries the UB-tree has mul- tiplicative complexity instead of the additive complexity of multiple secondary indexes. This results in dramatic performance improvements over secondary indexes.
Now look at the list of partners. -

Re:single shot cdYou could use Jigdo. That's what Debian uses. Instead of having to actually store huge CD or DVD images on you ftp site, Jigdo downloads all each file that supposed to be on the CD/DVD and then assembles them into an image file on the users system. One of the many advantages of this is that it's easy to update your images -- just upload the new files and change the
.jigdo file that specifies which files are included in the image.That's why Debian can distribute uptodate CD and DVD images of "testing" and "unstable".
-
CD Images of Sarge
There are already CD images of Sarge about (pre-release of course, and at the moment they are not bootable - waiting on the new installer).
Something else of note to look at Re: Debian is Jigdo.
Jigdo basically downloads all the individual files from Debian mirrors, and "makes" the CD image. Jigdo can be used on mirrors to avoid having to transfer the whole CD image (and if you run a mirror, you'll probably have all the *.deb's on hand anyway), while still being available for use by end users. As the *.deb's are more likely to be cached, wether in a proxy or via a mirror, this can result in a speed-up for downloading an image. It also supports upgrading only the files that have changed (eg: for keeping up-to-date images of stable), without downloading the whole CD image. Much better than trying to do something silly like rsync against the old image.
You can find jigdo at http://home.in.tum.de/~atterer/jigdo/, and the pointers for .jigdo files for debian at http://www.debian.org/CD/jigdo-cd/.
PS: I don't believe that Jigdo is limited to use with Debian, but like apt, it's another tool that was produced to address a specific need within the Debian community. -

IA64 and new P4s use ACPI.Both IA64 and the hyperthreaded P4s require ACPI. IA64s require ACPI for operation at all, and the hyperthreaded P4s require it for finding the number of pretend processors.
No big news here. Linux has sufficient ACPI support for most uses, as does FreeBSD. The full, nasty, evil interpreter may not work, but that's not necessarily a bad thing.

ACPI on Linux...

Re:Observations & ExperiencesI've noticed that most of the comments both in the article and others complaining about the 2.4.x kernels and various stability problems are running [...] and even Debian Distros.
Please note that the released version of Debian (2.2r5) ships with a 2.2 kernel exclusively. A 2.4 Kernel for Debian-2.2r5 is maintained by A. Bunk along with the required packages to run it.
Only the next release of Debian will feature a linux-2.4, still along with 2.2 (And 2.2 will be used by the installation routine).

Adrian Bunk has prepared packages to run 2.4 kernels on stable, available here
a) download the files to my desktop Mandrake system over a slow phone line, following dependencies by hand while trying to remember what I had already downloaded to not duplicate effort
.
.
.
FWIW, I gave up on Debian last night and am installing Mandrake, which, yes, I was able to walk into a store and purchase off the shelf, and which I've installed on other systems before.
Allow me to tell you a parable:
A man wished to purchase a car. He had to choose between an offering from Ford and an offering from Mitsubishi. (no reason for choosing these, they're just the first car companies that spring to mind)
So, in search of expert advice, he went to the house of his friend Fred, the amateur mechanic. Fred put his own cars together from spare parts all the time, and the man knew that he would have the answers. He found Fred in his garage, tinkering with some unidentifiable piece of metal in an engine.
"Fred," the man said, "should I buy a Ford or a Mitsubishi?" Fred paused, wiping some grime off his face, and said, "well, my last couple cars were Fords. You can get 'em real cheap if you buy the spare parts the factories would throw away anyway. Got my last car that way, and she's a beaut!"
So the man headed off to the local car factory, planning to buy the parts. He faithfully bought each part on a list Fred had made. This was very hard, because he had to buy each part from a separate factory, and he had to carry the parts home by hand, not having a car. Worse, he had to return several parts when he bought the wrong one.
After spending much time and money, he finally decided that Fred was wrong. Going to a local car dealer, he walked in and said, "I want a Mitsubishi." The dealer was helpful and cooperative, and an hour later, the man drove away in his new Mitsubishi, vowing never to purchase Ford again.
Now, one would think this man did not do the most wise thing possible -- after all, who would try to buy a car in parts, then compare it to buying a car from a dealer? But that sort of comparison is exactly what you're making.
If you've got the laptop set up, you should probably just leave it. But in the future you might want to do some simple research, including finding vendors who sell CDs of Debian. I understand that CheapBytes is particularly popular.
You might consider waiting, however, until Woody is released, as it will be a major step forward in terms of included software. Currently, it looks like Woody will be released sometime in December or January...but don't quote me on that.
