Re:C/C++ vs. Fortran

Not a threat to either company.
No official word yet on whether the company thinks there are any infringers.
Google doesn't look at the image, just the filename, alt tag and surrounding context. Likewise with Ditto. I fail to see how that involves "shapes, texture, color or resemblance to another image". There are other companies out there that should be worried, but the ones you mention are about as far from that patent as you can get and still search on images.
These guys are a closer match, but since they are doing 3D CAD/CAM models, perhaps they are safe to.
On the other hand... these guys (eVe Image Search Toolkit) could be in trouble if they are not the patent holders themselves.
This patent seems more applicable to finding images that have similar color properties and gross image shape, which could be really useful when looking for images that go well together when compositing, not for finding pictures of a specific thing (unless you have an example that is very similar to the object you seek.)
So for the forseeable future, metadata will be far more successfull at finding images. Computer vision is still incredibly primitive: more so than computer speech recognition ten years ago. -
More on Bob Full
This is really old news. RHex has been around for at least a few years now.
Bob Full is one of the lead scientists on the RHex project. His biomimetic approach is amazing. See the following link for one of his lectures.

There do exist bullets that aren't magic
I admit that DBC is no magic bullet. It's possible for a not-so-perfectly-tested module to have a defect such that it does not fulfill its contract. However, Sun has a vested economic interest in making the Java platform more reliable than the Windows platform alone; to this end, its developers most likely use elements of several software defect control methodologies in the JVM.
Let's try the empirical route. When and where have you learned of a critical bug in the Java platform's type safety as implemented, other than one caused by a hardware fault?

Neutrinos> Dark Matter is a theoretical concept we as to yet have not seen or detected.
Tell that to the neutrino guys I've worked with.
Neutrinos have non-zero rest mass, and hence are known and detectable dark matter. (It's worth noting, though, that they're "hot" dark matter, and "cold" dark matter is more like what you're complaining about. Neutrinos also only account for maybe 20% of the needed dark matter.)

Misleading article
The article is very misleading. PlanetLab is primarily developed by Princeton University. The claim that the network was "funded by Intel" is a huge exaggeration: Intel has merely donated some of the original servers, which are now only a fraction of the total number of PlanetLab servers.
You can read a more informative article about the background here:
http://www.princeton.edu/pr/news/03/q2/0624-planet lab.htm
Furthermore, I'd like to point out that most of the work on the PlanetLab infrastructure is done by grad students at Princeton University, not by Intel. -

How do they know it's fusion?
From the article it seems like Fleischmann saw more energy coming out than he put in (up to 250% apparently) and thought to himself:
"Aha! This must be cold fusion."
Is it just me, or does that seem to be a bit of a leap of faith? After all, if one sets light to petrol one gets more energy out than a match puts in. Surely there are other possibilities.
Occam's razor anyone?
I'm not sure about "strong evidence" from a single research laboratory either... -

Mr. Tomasi Please Read (Offtopic, Sorry)Did you know you can fertilize your lawn with used motor oil?
Normally I would never reply to a sig but in this case I feel it is important. The water I drink every day comes from my backyard and your sig seems to be encouraging people to pour used motor oil on their lawn to fertilize it. If any of my neighbors were to do this they would not only contaminate their own water supply but the well water of everyone in this neighborhood. One quart of oil can contaminate tens of thousands of gallons in an aquifer or even millions of gallons when spread into a slick on a body of water. And when it is in an aquifer it can take decades to dissipate. Please read some of these links:

Re:I don't understand the focus on airline securit"Brilliant" is not necessarily a word that means approval or admiration.

2. brainy, brilliant, smart as a whip -- (having or marked by unusual and impressive intelligence; "some men dislike brainy women"; "a brilliant mind"; "a brilliant solution to the problem")
3. brilliant, glorious, magnificent, splendid -- (characterized by or attended with brilliance or grandeur; "the brilliant court life at Versailles"; "a glorious work of art"; "magnificent cathedrals"; "the splendid coronation ceremony")
4. bright, brilliant, vivid -- (having striking color; "bright greens"; "brilliant tapestries"; "a bird with vivid plumage")
5. brilliant -- (full of light; shining intensely; "a brilliant star"; "brilliant chandeliers")
6. bright, brilliant -- (clear and sharp and ringing; "the bright sound of the trumpet section"; "the brilliant sound of the trumpets")

Re:Copy protected CD?
If it's "copy protected", it's not a CD.
Not exactly true. Every copyprotected CD-like disc out there relies to one of the following tricks:
a. Deliberate RedBook errors on audio tracks. Used at least on Cactus Data Shield discs
b. Data session at the end of the disc left deliberately unclosed. Used at least on Sony Key2Audio discs
c. Audio obfuscation driver that relies on Windows autoplay for installation. Used at least on SunnComm MediaMax discs (complete analysis here).
In the case c, the disc is perfectly standards compatible CD -- it could even have the CD-DA-logo. If the copy protection hurts you because you're using Windows and had Autoplay on -- well, bad for you, but on other OSes -- like OS X or Linux -- there are no problems ripping these CDs whatsoever. Neither in Windows, if you don't let autoplay run.
The bad thing is obviously, that it is damn hard to find out what was the technology used, as even the non-copyprotected discs often lack the logo nowadays. But I think most shops will normally accept returning of copyprotected CDs, if you'll just claim that they didn't work in your stereo CD player. In case of C, you don't really need to -- the disc will work, if you don't just act like a fool by letting Windows autoplay it.
Case A is usually worst, as these discs do not stand physical damage as well as standard discs. Deliberate errors also forces to use special tools when ripping. OTOH, in thgis case the copy will be better in quality terms than the original. In case B most drives are able to rip the audio tracks succesfully, at least using special software. There are some drives, though, which refuse to ever recognise these discs at all. -
Why are people so dense?
Now, correct me if I'm wrong, but sexual relations (the legal def as intercourse or otherwise!) by a boss with an underling is essentially the essence of sexual harrassment right?
Since you ask, you are wrong.
Only in the mentality of the US Christian Ayathollas it is comparable to have a blow job and try to hide it to sacrifiying thousends of lives based on false pretenses.
I know which politician did something about peace and combating terrorism (Clinton in Northern Ireland, or pushing the Middleast peace process, that only failed due to the pigheadness of ARafat and his cronies). And I know which one has worsened things (great, we now have another unestable country leaning towards fundamentalism with a hurt pride to avenge).
No brainer honestly.

Do some research!
This is a bald-faced "Urban Myth" go back and review the facts of the 2000 election and you'll find the Supreme Court in reality ended up being a non-factor in the outcome of the election.
Ummmm. Nope. Sorry. You're the one who is mistaken here.
The Supreme Court ordered that the recount be stopped (and, that is the ONLY recount, not "multiple recounts" as James Baker and the Republicans claimed over and over again during the press coverage of the 2000 election fiasco) and that the totals from the election night be certified. This DID have a huge effect on the outcome of the election, because, as was found by a group of eight news organizations that did a recount of the Florida 2000 votes, Gore won in a number of different recount scenarios, even if you don't count the extra illegally counted absentee votes that pushed Bush over Gore's vote total.
Your facetious "can't make an X" statement shows how little you know about what happened. The main problems with the 2000 election in Florida were:
1) Tens of thousands of people were incorrectly put on the felon list and removed from the voter rolls
2) The "butterfly" ballot debacle that caused thousands of votes (3:1 of which were likely to go to Gore) to not be tallied. These were punch ballots, and not "X marks the choice" ballots.
Now, were the Consortium recounts widely reported as a Gore victory? No. Why? At least partly because they were completed in November of 2001, while the majority of the country was in shock after September the 11th. I'm not saying this as some sort of conspiracy theory, but a LOT of the news coverage at the time was pretty soft on anything related to Bush, because many, many people (look at his approval ratings from that time period) thought that we needed to support our President during the traumatic times.
Next time, before you call something an "urban myth", why don't you do some research? -

Re:Humans are lucky...It is equally clear to others of us that nurture plays a much larger role than Sociobiologists believe. What sociobiologists try to explain as a result of evolution, or hardwired, is nothing of the kind.
In Why Men Won't Ask for Directions , Richard Francis exposes the hollowness of much sociobiological science with a detailed analysis based on work in developmental biology. He shows that much of what is pointed to as evidence by sociobiologists as the action of evolution is actually explained by the underlying biochemistry; in many cases, the behaviours are an artifact of developmental biology -- like nipples on men -- rather than the result of evolutionary pressure.
The book is fun, you will never see sex and gender the same way. He leads you through the lives of some bizarre vertebrates, while elaborating his vivid argument against both the 'science' and the underlying philosophical approach of the sociobiologists. It's an eye-opener for all who have only heard the sociobiologists and their non-scientific opponents.

khan
Khan is actually a title used in many asian languages, sort of like "sir" in English. Here's a definition.
The "kh" has a special pronunciation, as per this page: 'occurs in Hebrew and Arabic, in the German pronunciation of Nacht, or in the Scottish pronunciation of "Loch" (a voiceless velar fricative).' or the Dutch pronunciation of G in Gronigen.
But as is unfortunately the case too often, this is all lost on the average American.

C'mon, guys. Less raving! It's MediaMax.
I find it funny reading all these outraged posts about how the disc is not valid red book, etc, etc.
The protection on this disc is very light, and will really only catch the casual user. If you know what you're doing, it's very easy to bypass.
I find this protection a breath of fresh air. It is almost as if the publisher is saying "Here. If you know enough to bypass this, presumably you understand copyright law and won't swap files." No scheme will stop a dedicated cracker, so they offer one that doesn't even try. In fact, the publishers even acknowledge it isn't a very secure scheme. Yes, their trust is probably naive, but that's their problem not mine.
See this article for a description of MediaMax.

How it worksClever idea. The gadget apparently uses a pulsed solid-state UV laser to ionize a channel in the air between the shooter and the target. The plasma is a much lower resistance path than the un-ionized air, and so the discharge from the gun follows the plasma to the target and then to ground. Interestingly, at high enough intensities laser pulses like that can be self-focusing (pdf) .
Of course, you still need to hike around a whopping big capacitor bank to have this work over any reasonable distance, and the repeat rate of fire would probably be lousy since the capacitors would have to be recharged....

Re:The language does matter
Regarding item 2, I had a colleague at a University I worked at, which had a "proof" (I didn't look into it and it wasn't published but rather a good discussion and it was a bright guy) that a garbage collector was faster, in theory, in certain situations.
In a copying garbage collector, the work required is proportional to the live memory. With manual memory management, the work is proportional to the amount of garbage. So given enough memory, garbage collection will always be faster, "even if the cost of freeing a cell is only a single machine instruction" (Appel). Garbage Collection Can Be Faster Than Stack Allocation by said Appel is a good start if you want to know more.
The key phrase here is "given enough memory". And in my experience, I've never succeeded in giving real Java programs enough memory :->. -

Re:Depressing issue.
I designed one of the problem sets (homework assignments) for the intro CS course at Princeton University. The assignment is a digital signal processing one where you animate waveforms from an mp3, generate your own sound waves, and add a basic filter to a sound wave. All the sound stuff including decoding the mp3 file is done for you, you just have to manipulate the data. The assignment was intended to teach the use of objects in Java (we had students create a Wave class that had some built in capabilities to add two sound waves together, amplify/attenuate sound waves, and generate waves of a given amplitude frequency - musical notes are characterized by their frequency), and make them deal w/ arrays. FYI, here is the assignment. N.B: I'm sure I screwed up some technical sound details in there
Point of the post: I got responses ranging from I hate it to this assignment made me want to be a CS major. The people who were interested in CS/math/sciences loved it because they got to do something fun fairly simply. Those who were taking the course to fulfill a requirement or to dabble in programming hated it because it required them to deal w/ creating their own class and some math (fill an array with samples of a sin wave) and other stuff that required some thought/learning. They much preferred the assignments I hated that involved no creativity/original thought and were rather boilerplate. A lot of people (even really smart people) don't like being forced to think and much prefer memorization to critical thinking/problem solving. That's why, IMHO, many programs don't teach concepts (it disgusts me that in engineering classes the profs are "afraid" to give mathematical proofs for things b/c so many students hate them) or foundation - because too many people hate it and shy away from courses that focus on things that can't be crammed for and require understanding. -
Re:Precedent for "junk DNA"For example, a few centuries ago some...irrational....
This is some weird combination of revisionist history (the ancient Greeks knew about irrational numbers) and just plain making shit up (irrational means it can't be expressed as a ratio of integers). See Mathworld's definition of irrational number for one more credible, and more researched, version.
Some time later, in the 1800's... imaginary....Imaginary numbers under a variety of names were discussed at least as early the 16th and 17th centuries and credible sources claim references back to the ancient Egyptians; this reference also says the term "imaginary" was in common use at the time of Descartes (though makes no reference in the online material as to who coined the term). Many less credible online sources place the name as coming from Descartes and claim it to be dergatory, but many of those sites appear to be copying from some common source of unknown origin. So, the guess that imaginary was derogatory may be correct.
I suppose one of four (calling the fact of the name and date of discovery each as guesses at the truth)possibly correct speculations isn't bad for just spewing stuff that sounds credible

Re:Interesting, but what are the benefits of Java?

Re:If CVS was implemented in Java...Your post actually raises some interesting issues, but you will almost certainly be modded as flamebait because of your silly petty comments about older languages. There really are no bad languages, only bad developers. Except for Scheme -- it sucks (kidding!!)
There is some merit to talking about some mission critical programs being moved to java, but of course you have to recognize that VM's are vulnerable to all sorts of hacks.
I do think that java probably is preferable as a language for avoiding buffer overflow vulnerabilities, especially for less experienced developers. It will be interesting to see how James will stack up with the notoriously holy (pun intended--damn I crack myself up) Sendmail. There ARE other examples of java in critical situations, I'm sure -- but none spring to mind.
I do constantly use java to write the shell stuff that I know someone is going to bang on -- just because I haven't seen a root exploit from a java process yet.

Theorem proving languages
This sounds a bit like Alloy. Alloy is both a code modelling language (like UML), but structured in such a way that the model can be analysed automatically using SAT solvers (yeah, I didn't know what those were at first either. Here's a site with some good info on them).
Alloy's cool because you can use it to model code at a very abstract, high level (much like SPARK, it seems), although with Alloy you aren't tied to any specific language. The downside is that since the model isn't embedded in the code it's more useful as a design tool than something which will "guarantee" correctness every time you compile. -
