I had a look at the ZigZag article (http://jodi.ecs.soton.ac.uk/Articles/v05/i01/Nels on/).
Looks like Nelson reinvented graphs:

Take a directed graph ("zzstructure"). Its edges ("zzlinks") shall be colored (each color a "zzdimension"). Add the restriction: Each node ("zzcell") may have at most one outgoing ("posward") and at most one incoming ("negward") edge of a color.

So you've got it in a few sentences. And he's right: You can do interesting things with graphs. That's why there is graph theory. And visualizing graphs is interesting, too, and an active research field. Nothing "cosmological" about that.

BTW the "ranks" are the connected components of the shadow of the subgraph of one particular color.

So, first things first - I met Ted at The ACM Hypertext conference in Aarhuus in 2001. He gave a keynote and a workshop on ZigZag - which at once seemed totally obvious and very powerful. I played with the ideas for a bit, showed some things to him whilst he was a visting professor at Southampton and have worked with him here at the University of Nottingham before he went off to his current job, at The Oxford Internet Institutehttp://www.oii.ox.ac.uk/. It is a priviledge and an honour to be able to call Ted my friend - he has an incredible mind, a huge vision, and yes, he can code!

I've been working on using ZigZag to represent the deep interrelationships inherent in biological information. We've also been working on ZigZag as a phone/PIM interface and analysing the underlying structures. If you're interested in finding out more, read our published work:

No, but a steam powered vehicle did hit 127.66 mph in 1906.

Besides, Model-T's weren't speed machines, they were consumer machines that opened up the market to sectors who had never before been able to afford a car. A model-T modified for racing could reach 100 mph

Nescafe Hot was a flop. "In 2002, Swiss beverage maker Nestle SA tested a self-heating can holding its Nescafe Hot When You Want coffee in England. But the company ended the trial run after several months, finding the can did not heat the liquid to a consistent temperature, said Nestle spokesman Francois-Xavier Perroud. "It didn't pan out," he said. Nestle is still interested in the idea, which it believes will be popular with consumers, but it is "not aware of a self-heating can that lives up to our expectations,"

My mistake. The coffee forms a jacket around the container of lime and water, as in the diagram. Logical, really - all the heat goes into the coffee instead of burning your hands.

Indeed it is :-)

See http://www.dolphin.soton.ac.uk/June2001/nescafe.ht ml for more info

The way it would work is this:

A neural network is set up to control a audio-visual environment. You dynamically measure IQ via the proxy of the (highly correlated) evoked potential response of the subject and backpropagate an error signal through the multimedia neural net inversely proportional to the dynamic IQ of the subject.

Simple in concept. With a little luck we'd have people whose brains had been stimulated to a high IQ state without ending up with something like the lawnmowerman taking over slashdot.

What goodwill - the general public never heard of them. Google's product, on the other hand, is aimed at the general public - not the same product in either design or use. So there's no possibility of conmfusion.

Alternately, check out MailScanner for one-stop mail sanitization, virus checking, and spam filtering.

Best of all, it's a fit-once solution that will last as long as any other material might be reasonable expected to, off-setting energy demand all the while. Oh, and the colour is a rather fetching blue-violet depending on where you view it from :)

Here's a few more examples:

Research on photovoltaics in cladding systems done here in the UK at Southampton Uni.

The German cladding manufacturer Schüco has a variety of well-developed photovoltaic cladding systems:

More European examples

A 60KW solar roof cladding installation in Berkeley, California.

Ditto the University of Southampton. I've been working on a SW-related project, AKT, for the last four years; as part of this work, I was a member of the W3C working group (along with Jeff Heflin) that wrote the OWL Web Ontology Language.

Other places to look at are Jim Hendler's MIND group in Maryland, which has been doing some sterling work over the last few years (as an aside, Jeff used to be Jim's PhD student).

Mod parent down. This is the most unscientific nonsense I've ever read on /. In comparison to the overall energy stored in the atmosphere the energy taken out of it by windmills is negligible.

I refer you to a paper like this one to confirm for yourself that if you talk about heat and energy transport in the atmosphere you are talking in terms of PW that is Petawatt i.e. 10^15 Watt. The energy stored in the atmosphere is many magnitudes larger than the current 0.013 PW of global human power consumption (the average power consumption is about 2000 W per person i.e. given there are about 6.5x10^9 people on this planet you get the 0.013 PW number).

If you take into consideration that the mass off our atmosphere is 5.1 x 10^18 Kg and the heat coefficient of our air is about 1.005 kJ/(kg K) you can easily verify that an increase in atmosphere temperature by one degree Celsius stores about an additional 5125500 PJ in the atmosphere.

That means even if all of the given the current world power consumption was to be drawn out of the atmospheres it'll take more than 12 years to just get the equivalent of one degree change. Given the current inverse trend in global warming that'll be actually quite welcome.

This is of course just a quick and simple back of the envelope calculation but it should give you an understanding of the magnitudes involved and lay any doubt at rest that some windmills could potentially affect the world climate.

Really don't know what to make of the parent post. Suspect for a second that this was just astroturfing but then the posting history doesn't support this. Wass even claims an undergrad degree in physics. He really should know better.

Haven't seen anyone say this yet, but this is one of many projects based on the GPL ARToolKit. A friend of mine has another project here.

Its going to be a mail/file server. I think you don't need a ton of horsepower.......

It depends on whether you are planning on doing any mail filtering. I have a bunch of experience with MailScanner and ClamAV -- a sendmail server that normally eats 4-5% CPU will quickly start hitting 75% and more. SpamAssassin will add a bunch more to the load. As far as file sharing goes though, you are probably safe.

IMNSHO, this comment is unfair. Your condemning the product because you don't like this 'second-rate "hi-fi" ' company, rather than the merits of the product.

True, but it's still under development. I've seen a demo of the system, and the movies accurately reflect my experience. I suspect we'll start to see technical details via professional society papers once the system is in production.

24 years? I don't know, but I did see a demo of this 10 years ago.

I won't argue that Bose's products are overpriced for the sound quality, but for some customers, they do have greater appeal than simply sound quality - for example, the WAF/SAF appeal for their acoustimass speakers is very high.

In any event, are there any videos that demonstrate the Porsche and GM systems? I like to compare the performance of the systems (well, as much as you can compare them in a video).

Why not? Active vibration control and dynamics are based on the same mathematics as acoustics, so it's all related. I went to school to learn to make speakers and wound up becoming an expert on train ground-borne vibration

Of course as a noise & vibration guy, Bose's system interests me because it could help reduce wayside ground-borne vibration from auto traffic (and even railroad traffic if the price was sufficiently low). Yeah, it's a pipe dream, and if it does happen, it would be several decades, but every little bit helps.

There is no energy crisis. 1 sq-m of sunshine == 1 kilowatt, the oceans have trillions of tons of methane hydrates.

The problem is one of $$$, big business, politics, and distibution. It's not technological, it's not for want of supply.

Enough solar energy falls on earth in less than an hour to power the whole planet's human wants and needs for a year.

Heck I get at least 900 virus emails everyday sometimes over 2000 a day.

Thanks to the guys over at Clam Anti Virus and MailScanner most of these get caught at the mail server.

We have a daily humor mailing list with a few 100,000 subscribers and every time a new virus comes out we get blasted from all the unprotected windows/outlook express users.

To make sure we don't get infected and send out virus to all the users we use FreeBSD for our desktop OS and Evolution as our email client.

Oh and then there is all the spam we get sent, thanks to SpamAssassin for filtering most of this out.

Those artificial sounds bear only a modest resemblance to actual waterfall sounds

If viruses/worms/trojans spread by email are your biggest concern, an obvious solution would be to scan all incoming email.

If students are using the university-supplied addresses, the university's server should be doing some sort of virus check - there are numerous commercial (pay) solutions available depending on your config (Norton, McAfee, Trend Micro, RAV, Sophos, etc), and there are even some open-source ones, such as ClamAV (which is updated very frequently, and is, of course, free) which you can integrate into your mail system.

If your university doesn't want to modify it's existing server, you can "front-end" the existing mail server with another server running a virus-scanning solution, such as the open-source MailScanner, which simplifies integrating virus and spam scanning into a mail delivery program (it can use ClamAV, for instance), which would then forward the email to the existing server once scanned.

As well, if you wanted to be extra careful with 3rd party email addresses, you could block POP3 and IMAP ports to any server other than the university's at the firewall, so that students would be forced to forward their 3rd party mail to the university's server (which would be scanning for viruses). Or, you could set up the firewall to redirect all POP3 requests to a box running POP3Vscan (again, open source, so free), which is a "transparent" proxy would scan incoming POP3 email for viruses. Not sure if there's an equivalent IMAP proxy solution, however...

Anyway, you do have low-cost options for preventing these things in the first place.

I was refering to this rather confusing slide, but lower frequencies do sound more plausible (not that I'm a radio engineer or anything)

I'm surprised they got a radio link to work through 60m of ice. They're apparently using 1.8 ghz radios.

If it turns out to be true, this will be super-duper-extraordinary - the man is probably in his 70s. G. H. Hardy wrote: "No mathematician should ever allow himself to forget that mathematics, more than any other art or science, is a young man's game". Wiles proved FLT at 40, Perelman of the purported Poincare proof is in his 30s... this is similar-level stuff. The only thing I can think of that even comes close is Fred Galvin in his 50s (?) proving the Dinitz conjecture.

You can follow discussions on sci.math and fr.sci.maths. Or read about how similar asymptotic proofs about properties of primes failed. Remember, this is arxiv - in the age of electronic preprints, you get many good proofs like Perelman's along with almost-proofs like Castro-Mahecha's and Dunwoody's.

I work at a UK university and we're introducing a new system to deal with spam. We've already got an in-house product, MailScanner which does the detection job pretty well, but our mail servers are quite loaded with junk.

We're about to offer a "delete at gateway" option, so our users don't have to filter their email and lessen the load on the mail servers at the same time. This service is optional, so our users can choose whether they want it, but we'll be strongly encouraging them to use it.

Additionally, they can set their spam threshold, so they can delete most spam, but review the borderline cases.

Virtually no scientist agrees with Penrose. His Godelian argument on AI has been completely and utterly disproved in this paper.

Formal refutation of Penrose's Godelian argument

Here we go again... Penrose's argument has been formally refuted.

That is because of the Lithium ion battery chemistry. This discharge curve (the first graph) shows voltage dropping off almost exponentially once it first starts dropping. Yep its offtopic. But you asked.

ATRAC3plus is a Sony proprietary standard, with all this complex licensing issues this entails, hence it's unlikely anyone else will be using this technology, particularly in the free/open source software community. Sony are somewhat canny about releasing details of the licensing, so I haven't found anything more detailed about their licensing strategy than this. This paper also gives some peripheral insight.

But the plan was scrapped when the robot, named Dalek, went on a killing rampage.

You're right about extra hardware. However:

ClamAV seems to have the best reviews.

I snarfed all this out of a /. comment or two a little while back, and mailed the links to my boss, who was recently complaining about the high cost of email server antivirus software. I haven't tested any of them because I don't have a colocated server and comcast does not offer static IP addresses for love nor money (or at least, I haven't found the right person to make the offer to yet) so I don't run a mail server these days.

1) SM4 was canceled due to cost, we believe SM4 can extend the useful life of Hubble 4 or 5 years. Not True! SM4 was canceled primarily due to safety reasons. Please remember this, SM4 was Not Canceled due to Cost!!

2) Hubble is in 100% working order. Not true! The gyros which point the telescope are slowly failing.

3) Adaptive Optics/Clever Image Processing/Ground based telescope are better than or equal to Hubble. Not completly true! AO can image single objects to better than hubble. But AO has poor field of view! For reference, the UDF images have a field of view of 180 arcseconds square. AO fails above, 30, and degrades quickly above a few. Worst, AO needs a bright star to work. There simply are not enough of these stars! I can't reference this, but experts in the field think that it will take 30 years to get to Hubble's level of performance with AO.

4) Finally, AO will never work in at UV or near/mid IR wavelengths.

I am an astronomer, and I feel it is my duty to inform the public about the benefits of Hubble. HST serves a unique roll to the community. We should all understand exactly what the risk will be to fly SM4 before we lose 4 years of Hubble!

I had never heard of LHA until recently, when my GF started writing "dollz." Gnome KISS is a KISS doll viewer, and they are all the rage in Asia (or were last year, anyway). KISS is like paper dolls that you dress up. You can see some of my GFs work at the bottom of this page. There are actually some fairly sexy ones, but I can't find any on a quick google. Anyway, these dollz sets use LHA compression, and finding a copy that would even compile on my machine took days, and sometimes things still don't work correctly. LHA is a PITA for me. P.S. A javascript version of a doll is here.

We use MailScanner which can work with Sendmail or exim and it supports many different AV programs.
It doesn't just do viruses though, it can run Spam checks (with or without the help of spamassassin), Filter out (and remove) dangerous HTML, filter/remove file attachments and has lots of other useful features.

Definately worth checking out.

UltraSparc has a 64bit userland if you care to compile it. Currently the only distribution that I know of that provides one is the Aurora Linux distribution that is based off of RedHat 7.3. More information about the project is Here at the Aurora Linux website .

Currently its 64bit userland is limited to the C library and a few support libraries. This allows you to compile applications in 64bit mode so that they can gain the benifits of 64bit mode.

Most cases using 64bit applications cause the machine to be slower due to the doubling in the length of the addressing pointers and other factors. Better explination is available in their FAQ entry on this 64bit vs 32bit issue .

Mailscanner is a spam filter,

It's free, easy to setup and works really well.

However, in general you are right, the colour corrections are arbitrary and don't match the "real" colours. Moreover, the brightness stretching and image processing often changes the colour in strange ways. There's a recent paper which discusses the problem and presents some solutions.

Well, a quick search on Freshmeat (bookmark it, you'll find it very useful) suggests the following:
If you're not after actual re-touching capability, VIPS might be what you want. (Oh, you are. Oops.)
Well, for the princely sum of US$25, JPhotoBrush Pro looks good (there's a trial version available for download).
For very basic manipulation, IV might do. And if you want something really basic...
If you're willing to play with something considerably less mainstream, PyWiew caught my interest for being pure Python. Does sound a bit esoteric, though.

Finally, you could see for yourself what else is out there. There's more than freshmeat, of course. Like the Linux section of Tucows.

Incidentally, if you have the time to learn it, Gimp can be very useful. Best way (like all *NIX at home learning) is to find someone who knows what they're doing and get them to teach you.

P.S. - If you like Linux, try FreeBSD sometime. Not as popular or well covered, but has advantages too.

HTH, etc.

I think the reason they don't have the necessary licences is due to them not qualifying for them rather than the cost of obtaining them.

Found this little tidbit on the web
pdf
about another license that is needed to build dvd players. It says:


In order to manufacture any sort of DVD related item, whether it be DVD discs (i.e. the movies) or the players (DVD Players or DVD-ROM's), the manufacturer must obtain a license from the DVD Copy Control Association (DVD CCA). The DVD CCA is a non-profit organisation responsible for licensing CSS to such manufacturers. It is not possible to use the DVD logo, or even the word DVD without this licence.


When the manufacturer make players that can skip/ fast forward anywhere, advertise prominently how to change the region code etc, they can have their license revoked. In reality this only really prevents them from using the logo and the word dvd. Like your article mentions it doesnt stop grey importing of these products.

The CSS license is more expensive too, at $15,000 a year.

look at point 3 here
