Re:Yikes, How long ...
War and Peace is online as a pdf (and in other formats)
(and has been for quite a while), rather nicely formatted too.
Check your own download times, no doubt they will vary :-p ;-) :-)

opposable thumb
The wonder never seizes to amaze me...
The biggest question; as more sophisticate motorized artificial limb gets, more sensitive sensor to control it requires.
If the question above is solved with "clever" routine to detect movement in sync with rest of fingers (ie. gripping torch.. hem or just giving thumbs up or middle finger), I'm assuming most basic movement will be predetermined/predefined according to how the sensor detects the motion or object by means of basic push/pull mechanism from wrist muscle.
If then (and I said "IF"), won't it be more "clever"-er to have prosthetic controlled by nerve?
For example, MES Robotics has pretty nice pictures of future projects regarding similar concept.

This shows some interesting trends. First off, it looks as though the greatest retreat in recent history was during the 1940s. The page goes on to say that there was a bit of an advance during the 1990's but that 2002/2003 were very warm winters and there was a great deal of retreat then.
When I go to sites showing retreat, a lot of them show data from the 2002/2003 cycle. I think both sides are cherry picking.
Interestingly the 2002/2003 retreat is reflected in the susnspot cycle:

Oh -- and if you look at the sunspot cycles from 1750 to present there seems to be an overall increase in activity: http://science.msfc.nasa.gov/ssl/pad/solar/images/ zurich.gif
I'm sure human kind is responsible for some part of climate change, but I believe that other forces are at work as well, and may be more important than Greenhouse gasses. I think we should focus resources on adapting to those forces and I do believe a strong economy will be the backbone of this adaptation. -
Re:I like GOTO!
ur comment Callbacks are everywhere in C++ although these days gives an impression as if, callbacks are part of standard C++ way.
Well, callbacks are a fairly straightforward concept. They're most commonly used in things like GUI programming, where you do a lot of (asynchronous) event handling.
But more generally, callbacks are just a very specific example of functional programming, which is just another style of programming that emphasises functions as first-class elements. And because C++ supports several programming paradigms, you can do object-oriented programming, functional programming and/or generic programming - often all at the same time.
Just like in Perl, there's more than one way to do it. And there isn't any one "correct" way - whatever gets the job done is fine.
If u r aware, OOP was first implemented on pascal (rather than C).
No.
Object-oriented programming is widely recognised as first being implemented on a language called Simula in the 1960s. 1962 to be precise - for Simula I - though Bjarne Stroustrup based C++ most closely on the OO concepts in Simula 67 (1967).
Pascal was first implemented in 1970, though the original Pascal didn't support object-oriented programming.
And Pascal had inherent capability, while C++ did not.
I'm not quite sure what you mean by that. Most implementations of Pascal don't support object-oriented programming at all, much less have "inherent capability". Those implementations that do support OO-style programming usually aren't called Pascal - eg. Delphi, Oberon, Modula-2.
I could go with the list of many things. For example: C++ did not provide any mechanism to identify whether this object is instance of *THAT CLASS*.
You're using your terminology confusingly here, so it's difficult to work out exactly what you're saying. But I can say that I've only seen a few occasions where it'd be useful to work out if Base* p is actually pointing at a Derived object, and usually those cases arise when you've started out with a bad design or bad logic. Usually the whole point of having a (pointer-to) Base is that you're supposed to rely on using Base functionality. You're not supposed to care if it might actually be a Derived, the only thing that should matter is that it is substitutable-for a Base. If you need to access Derived functionality, you should have a Derived.
But anyway, in those cases where you're dealing with someone else's badly designed code, a dynamic_cast should be enough to get around it. Take your Base* and try to dynamic_cast it to a Derived* - if that fails, you haven't got a valid pointer-to-Derived. Go find the person that built the code you're using and kick them. Hard.

Quote from Lessig's 'Free Culture'This is particularly interesting, as photography was one of the most important examples cited by Lawrence Lessig in his book Free Culture for lack of regulation conferring advantages to society.
A relevant quote from Free Culture (original text available available here):
What was required for this technology to flourish? Obviously, Eastman's genius was an important part. But also important was the legal environment within which Eastman's invention grew. For early in the history of photography, there was a series of judicial decisions that could well have changed the course of photography substantially. Courts were asked whether the photographer, amateur or professional, required permission before he could capture and print whatever image he wanted. Their answer was no.6
The arguments in favor of requiring permission will sound surprisingly familiar. The photographer was "taking" something from the person or building whose photograph he shot--pirating something of value. Some even thought he was taking the target's soul. Just as Disney was not free to take the pencils that his animators used to draw Mickey, so, too, should these photographers not be free to take images that they thought valuable.
On the other side was an argument that should be familiar, as well. Sure, there may be something of value being used. But citizens should have the right to capture at least those images that stand in public view. (Louis Brandeis, who would become a Supreme Court Justice, thought the rule should be different for images from private spaces.7) It may be that this means that the photographer gets something for nothing. Just as Disney could take inspiration from Steamboat Bill, Jr. or the Brothers Grimm, the photographer should be free to capture an image without compensating the source.
Fortunately for Mr. Eastman, and for photography in general, these early decisions went in favor of the pirates. In general, no permission would be required before an image could be captured and shared with others. Instead, permission was presumed. Freedom was the default. (The law would eventually craft an exception for famous people: commercial photographers who snap pictures of famous people for commercial purposes have more restrictions than the rest of us. But in the ordinary case, the image can be captured without clearing the rights to do the capturing.8)
We can only speculate about how photography would have developed had the law gone the other way. If the presumption had been against the photographer, then the photographer would have had to demonstrate permission. Perhaps Eastman Kodak would have had to demonstrate permission, too, before it developed the film upon which images were captured. After all, if permission were not granted, then Eastman Kodak would be benefiting from the "theft" committed by the photographer. Just as Napster benefited from the copyright infringements committed by Napster users, Kodak would be benefiting from the "image-right" infringement of its photographers. We could imagine the law then requiring that some form of permission be demonstrated before a company developed pictures. We could imagine a system developing to demonstrate that permission.
But though we could imagine this system of permission, it would be very hard to see how photography could have flourished as it did if the requirement for permission had been built into the rules that govern it. Photography would have existed. It would have grown in importance over time. Professionals would have continued to use the technology as they did--since professionals could have more easily borne the burdens of the permission system. But the spread of photography to ordinary people would not have occurred. Nothing like that growth would have been realized. And certainly, nothing like that growth in a democratic technology of expression would have been realized.

Re:as long as we don't go to ALL the moons
Haven't done any missions to Neptune? I seem to remember being in the Air & Space Museum in August of 1989 when we received the first pictures from Voyager 2 at Neptune; they had a little printer there & were handing out copies. BTW, this was 3 years after V2 had passed by Uranus, yet anOTHER gas giant in the solar system.
Anyway, try looking at http://voyager.jpl.nasa.gov/science/planetary.html . You'll find something along the lines of "...the additional flybys of the two outermost giant planets, Uranus and Neptune, proved possible...."
As for Neptune being "...supposedly a Gas Giant...." we knew that *before* we got there. Apparently, we can do wonderful calculations of mass & size based on earth-based observations of planetary bodies & their effects on other solar system objects.
Oh, and according to http://www.astro.uio.no/ita/TNP/nineplanets/neptun e.html, 13 known moons. Probably a lot more.... -
Hidden Love Message in Firefox AdDid anyone notice/hear that there was a hidden love message in the ad? Says so here. It was said:
"In the search of my own name (which I found) in the pdf, I came across a scandinavian love statement "Nicolaj Elsker Helle" => 'Nicolaj Loves Helle'."
Pretty self explanatory. There is also a screenshot of the thing too. Credits go to the observant Bad_Byte. -
Re:Great Computer Scientists
Don't forget Kirsten Nygaard and Ole-Johan Dahl who invented object oriented programming. I had the pleasure of meeting Nygaard before he passed away and he was a very dynamic and interesting person with interests outside computer science (he was active in Norwegian politics), and was very engaging. He will be missed. I believe Dahl also passed away, but unfortunately I never got to meet him.

Norwegians showed a downward trend
After these kinds of results, questions are raised about the way these tests have been conducted, and wether there are better tests.
I've heard ROSE, The Relevance of Science Education fielded as a better alternative, and that Norway would do better if there was just fewer countries in the test.
But this time, Norwegians went down the ranking since the last PISA-test. If this an absolute decline, the debate about better tests is not as relevant: Norwegian children today do worse than they did a few years ago.
Some politicians call for more teachers. But Norway uses a lot of resources for education allready. When it comes to learning for each dollar/krone/pound we're among the worst.
Lack of basic skills in maths and language is also hampering higher education and the workplace. It results inn worse economic results.
One possible correlation could be that Norwegian classrooms are among the most noisy and least disciplined. Improving that situation could improve the results.
One of my associates suggests that the really good teachers should be given bonuses. But how will that go over with unions and people who want to keep people "equal" at all cost?
More links for Norwegians: Norske elever nedover i rangering -
This exists in Norway already
Its called Felles Systemet (The shared system), and it makes many processes in the education sector VERY much more efficient
Outsiders, especially those from the USA think that this is a potentially bad idea, because it is a threat to negative freedom, however these types of system, merely distribute information to people who have access to it already in a more efficient manner.
Ironically, because the system becomes so much more efficient, the total number of people with access to this "private" information decreases -
Recordings of my and a friend's automatic pianos!
Actually, player pianos can sound really cool, and they are NOT obsolete antiques from the past.
The sound is completely real, even better than the most costly surround system that ever excisted.
That is, if you tune the piano and restore the inner workings correctly, of course, in addition to being a good pianolist.
The automatic mechanism operates via a complex maze of vacuum hoses, valves and pneumatics (small bellows) and the piano roll which contains holes read by a tracker bar which tell small pneumatics when to collapse, which in order, moves the keys of the regular piano, something which is further illustrated and explained here.
Nearly all player pianos can be played by hand as a regular piano by the way. One interesting detail is that on European pianos, the keys often don't move when the player plays automatically, while on most of the american ones, the keys move like we see in those western movies. Some pianos have electrical driven pumps, most others have foot pedals - mine has both! Pianos with food pedals are very easy to pump, if they are in tight working condition!
Here are a some examples of high quality mp3 recordings of two old pianos, one Stroud pianola residing in an art café, called Thomasgaarden in the old norwegian copper mining town Røros and my own Weber Pianola !
Lion Tamer Rag Artcraft roll played on the Weber piano
Frühlingsrauschen by the norwegian composer Christian Sinding. Aeolian roll played on the Stroud piano
American Patrol Aeolian roll played on the Stroud piano
Chicago March Artcraft roll played on the Weber piano
Can-can Some old noname roll played on the Stroud piano
And yes, I also recorded St. Lois Blues and Tiger Rag when I visited that café last summer.
One should notice that even if the Stroud pianola is somewhat untuned, its tone is quite better than mine, which sounds more like a perfectly tuned home piano ready for taking those boring piano lessons. But guess what - there no more boring piano lessons to take when you have an automatic piano!
And if I need more rolls, My friend Douglas Henderson, who is the mastermind behind Artcraft still supplies newly made rolls!
Artcraft is by the way a one man business where the rolls are made the hard way with this amazing punching equipment.
Here are some pictures of the inside of my piano - and yes, I should long ago made a home page with these pictures.
Did you by the way get distracted by the LGB train on top of my Weber piano?

And yes, I also recorded St. Lois Blues and Tiger Rag when I visited that café last summer.
One should notice that even if the Stroud pianola is somewhat untuned, its tone is quite better than mine, which sounds more like a perfectly tuned home piano ready for taking those boring piano lessons. But guess what - there no more boring piano lessons to take when you have an automatic piano!
And if I need more rolls, My friend Douglas Henderson, who is the mastermind behind Artcraft still supplies newly made rolls!
Artcraft is by the way a one man business where the rolls are made the hard way with this amazing punching equipment.

"It is the position of many Biblical researchers that most of the Old Testament comes from other, more ancient writings.
Even ** Jewish ** writers admit that most of the Hebrew writings were merely taken freely from Sumerian, Babylonian, Egyptian, and even Greek sources.
- Horace Meyer Kallen, at one time a professor at the Jewish New School of Social Research, said that the Book of Job was lifted bodily from an early and obscure Greek play.
- Scientist and author Immanuel Velikovsky admitted that there are "many parallels" between the Vedic Hymns and the Books of Joel and Isaiah.
- Hebrew scholar Zecharia Sitchin claimed that the Book of Genesis is based on the Sumerian creation myth.
- The story of Noah comes from the Sumerian legend of Gilgamesh.
- The Psalms were taken word for word from Akhenaton's Hymns to the Sun, written 600 years earlier in Egypt.
- The Ten Commandments (3,5,6,7,8,9,10) were taken from the Egyptian Book of the Dead

Re:radio pollution and the shannon limitHmmm. I don't agree with you here.
What you say is true in the absence of mutipath propagation (without independent fading). It is not true for an independently fading channel. Using MIMO on an independently fading channel (ie. multiplicative noise) does allow capacity to exceed what is possible in a SISO system operating at the Shannon limit.
I refer to to Foschini's seminal paper on the subject.
This web page sums it up:
MIMO systems retain all the properties of SIMO/MISO systems, since in some sense the optimization of the transmitting and receiving antenna elements is carried out in a superset of that of SIMO/MISO. In reality, MIMO systems offers advantages which go far beyond that of conventional smart antennas, as was first hinted in a breakthrough paper by J. Foschnini at Lucent Tech. in 1996 [Foschini96]. In this paper, Foschini shows that if the NxM channel matrix describing the wireless link in a M-transmit N-receive system has ideal independently fading elements, then the capacity of such a system grows linearly with the smallest number of antennas min(N,M) and no longer with the log function. An incredible improvement over the more traditional SIMO/MISO case. A similar result was also reported in [Telatar95]. In parallel, Foschini also developed a practical transmitter/receiver algorithm to beused in the MIMO context: the now famous "BLAST" algorithm [Foschini96]. Later another breakthrough scheme was proposed by ATT-Labs based on the idea of space-time coding [Tarokh98] to extract diversity gains in MISOthen MIMO.
I'm interested in any objections you still have, just in case there is a shortcoming in my knowledge.

Re:Wait for Longhorn
Many large companies out there are running Windows on the desktop and connecting them to Linux servers. I think when Longhorn is released they may not have any choice about what server software to use anymore.
Well, my university has got only unix/linux backend servers, and mostly windows 2K/XP clients. If Longhorn won't play well with the Samba/IMAP solution on the unix servers, they aren't going to upgrade to Longhorn. I doubt MS will put themselves in this position. A _lot_ of major businesses will simply choose to not upgrade. They are concerned with getting stuff that works - in the cheapest possible way. Longhorn would have to include some _really_ powerful effectivity-producing functions if businesses are going to change their entire server system just to get it. And by the way, universities and colleges are probably really important to Microsoft, because they need young people to learn their products. Most universities (at least in Europe) use unix servers for everything. MS isn't likely to upset them too much. Universities have clever sysadmins who know damn well how to set up *nix graphical clients as well. -

Re:Prion propagation
> My point regarding herbivoires is that if we observe cattle are built for eating vegetation and we call them herbivoires, it doesn't mean they can't get the same sustinence from meat.
Yes it does mean exactly that. Take a look at Dr T. Campbell's studies. He is a bio-researcher for 40+ years, at Cornell.
> Words like "natural" don't fit into it...
Ugh, what do you think Cows have been eating for the past say, few million years?? They weren't cooking meat on the BBQ, mate.
How do you think Mad Cow Disease spreads? When the dead cows are ground up, and fed to other cows. It's a little hard to get, when they don't eat other animals.
> do you have a better idea as to how to dispose of the animal remains?
We never had a lot of dead animals, since they were for the most part healthy. If you have a lot of dying cows, you got bigger problems to worry about.
We usually buried them, so they could be natually broken down (bio-degradable), and replenish the soil.

Re:Seems logical
> Is that why the PS2 is an absolute horror to program for (as seen by the poor-looking games that come out on it)?
Partially.
It's a multi-processor machine - It has (only) 7 "cpus".
You think multi-threading is hard with 2 cpus?! Try keeping the EE (main cpu), VU0, VU1 (the 2 vector units, with 4K and 16K of RAM respectively, used for physics, and transorms, respectively), the GPU, and shuttingling data from the IOP to main ram, and IOP to the SPU, ALL in sync, *without* data stalls. Gee, you think this is trivial? ;-)
> Having Linux (which the PS2 does) doesn't seem to have made development any easier.
I'm not aware of any professional game developer using linux on the PS2. It already has it's own propiertary OS - you don't need a more bloated one. Every K counts, when you only got 40 megs total RAM.
You only have 4 megs of VRAM (video). After reserving memory for the screen (640x480), double-buffered, and a z-buffer, you only have ~ 2 megs left. Guess we'll have upload textures every bloody frame. Shit, how come we're out of main memory?! Fortunately none of the sound data has to even touch main memory.
> The developers that don't have a huge budget can't afford to make PS2 games, they flock to Xbox.
Dev kits are expensive whatever route you go.
One of the factors is that the XBox is way easier to develop fore. Most PC developers can easily get a handle on the 733 Mhz + GeForce 3.

Re:Why not near coasts?
How come these are never reported near coasts? At the frequency they were detected, you think there would be a tsunami event somewhere every week or so.
My understanding of them is that they aren't a single "wave" traveling along, carrying some large amount of energy. Instead, the appearance of a rogue wave is just a temporary concentration of the local wave energy into one spot.
It's a constructive interference effect, and doesn't last long or travel far. Longer waves move more quickly than shorter waves, so by chance you could get a few different waves that all catch up with each other and produce a temporary HUGE wave in one particular location. The individual waves then drift apart as they move at their different rates.
The whole controversy is the math that goes into predicting how common such a coincidence is. I do not actually understand the math involved, but my guess is there is some effect that makes it easier for the waves to line up with each other to cause the effect. (Sort of like a magnetic attraction -- as the waves pass each other, something helps the phases line up more than a simple linear combination would suggest)
There is an EXCELLENT animation(animated GIF, 1.7MB) on the Karsten Trulsen site linked to in the story here. It shows how intentionally lined-up waves of different frequencies will all catch up with each other to form a large local wave. It then also shows how that same sequence of waves can be placed in amidst "normal" ocean waves, and the same effect still appears. Very cool to watch.
A tsunami, on the other hand, IS a single, large-energy wave, and is a completely different phenomenon.

Re:Igloos.
Igloos are made of snow, actually. You just have to find the right snow: a drift at least 60 cm deep and very hard packed by the wind. Then you cut blocks with a snowknife (a saw works surprisingly well, too). And yeah, I've built plenty of 'em.

iPAQ or Zaurus... Avoid PalmOS
I have been using PDAs for precisely this function for about 2 years now. I avoid eBooks like the plague because of DRM and other stupid old technology features (like pages). (For a good example of the limitations of eBooks read Chapter 10 of Free Culture by Lawrence Lessig). I also use PDAs to read news I gather from the Net. From my experience:
- Zaurus:
The webbrowsing and text viewing applications are fairly fast once they have been loaded into memory. NetFront (the webbrowser) supports CSS and properly renders PNGs. Web pages are generally pretty, although getting large fonts to work is a bit of a hassle. Both CF and SD/MMC cards are supported.
The screen on the Zaurus is unbelieably bright (especially if you have used an iPAQ before). The colors are breathtaking. The screen is really amazing. The resolution is also really 640x480 like on a desktop (for post C700 models).
The Zaurus battery is rechargable and replaceable like a cellphone battery. It lasts for hours even when playing mp3s.
-
iPAQ:
PocketIE is very slow. It starts up quickly but loads pages slowly. It does not support CSS and renders PNGs improperly. It often crashes or locks. The screen cannot be scrolled while it is loading. For older web pages, it is not bad, though.
Text is loaded in PocketWord. This is, for lack of a better word, a beast. It is extremely slow, and you would not want to read with it. If you have a CF card expansion pack, forget reading text files. It cannot handle large text files (read: Gutenberg etext files) well or at all (I have not tried in a long time). If you have a CF card expansion pack, forget PocketWord: It will not work.
The screen is bright enough and the resolution is good enough for reading. The colors are nice enough. In addition, the iPAQ comes with a sort of sunscreen case, which makes it readable in extremely bright sunlight (that is a difficult feat even for paper books).
My iPAQ does not have a replacable battery, but most of the new models I have seen do. The battery life is very good. It should last many hours even when playing mp3s. There are expansion packs with extra batteries.
-
PalmOS:
From what I have been told (by vendors), the Palm does not have a webbrowser. I know there are specialty programs, like Plucker, for converting web pages to PalmOS compatible formats, but I think this is terribly old fashioned of the Palm people to leave this feature out.
The displays on Palms I have looked at in stores have not impressed me. There could be a model with an unbelievable display, but I have not seen it.
I cannot comment on anything related to batteries because I have not used a Palm.
For the first two reasons, I never waisted my money on a Palm. It seems they are trapped in a time warp of what "PDA owners" of 1996 wanted or something. They do not seem to be concerned with putting a computer in your pocket. For people who use PDAs for their PDA functions, however, I have heard that Palm is the best.
Finally, I have not used actual eBook or PDF software on any of the three. I think HTML is the way to go anyway. I just want some pretty text. I do not want pages or DRM or other restrictions. I also like to be able to scroll text. I also want images, but I do not want them locked into the document where I cannot view them separately (many webbrowsers, PocketIE in particular, shrink images to an unreadable size, but image display programs will still display them properly).
