Quite a bit of research around here gets funded by Europe.
I will post a link for our students in the history of computing section of our Orientation in Computer Science course.
Convoluted? Let's compile a ZX-Spectrum emulator using this old C-compiler to use the PDP emulator, running a ZX Spectrum emulator, running a basic interpreter to run a computer game.
If the hand is severed two changes occur either of which might be detected: (i) the blood stops flowing, leading to a change in the Doppler signal (can be integrated into fingerprint scanners as well), and (ii) the blood in the arteries also becomes deoxygenated, leading to those showing up as well. I do not know which is used.
I suddenly have this mental image of the device shouting MURDERER at 100dB when it detects a severed hand of a client. Could be a neat addition.
It blew up a ship in Asterix on Corsica.
Reported to be rather "pungent" as well
OpenSUSE upgraded seamlessly from 10.X to 11.X to 12.X for me. It work fine even to the point that between 10.X and 11.X the system partition was upped from ext3 to ext4, but it left the user partition untouched.
I work with a Debian-based distro at work. As long as my compiler/matlab/LaTeX work (oh, and a browser) I am happy with essentially any OS. Multi-media (sound in particular) can be a pain now and then under Linux. On the other hand, I like it when my computer SHUTS UP.
I have used OS-X when visiting other institutes and had no problems with it. The only problem for me is that the current crop of MacBooks in the size I want don't have nVidia graphics (me use CUDA).
I would tax the politicians first, they seem to be producing far more hot air than anybody else, and heating that air must be fuelled by burning carbon-based stuff, so they are producing excess CO2.

I wonder if I could confuse would be code breakers by using Welsh (encrypted that is, although places like the above look like crypto to the uninitiated eye).
That is a typical MS fanboy dig at linux! Typical Steve Balmer FUD, and totally unfounded too!!!!!!!!!
I, I, I,....
Oh wait, you are talking real penguins. Please excuse me; do carry on.
Sorry, couldn't resist

Don't forget a packet of peanuts!
It is one thing to take the pictures (essential first step), but it does not end there. What is easily as important is automating the analysis. With the glut of data available, manual analysis is often unacceptably slow. This is one reason we are working together with European partners on massively parallel analysis of huge image data sets. This would allow rapid analysis of damage in the aftermath of disasters, among other applications.
Given that it was found in China, stir frying with ginger, garlic and a variety of vegetables is more appropriate. Just add a dash of light soy sauce and rice wine vinegar at the end.
Darn, now I am hungry
At least he does not shovel it into his nose or ears.
Going berserk as a warrior served a similar purpose against human opponents in the past.
Could well work against robots (and perhaps also Vulcans, or anybody else thinking logically)
Nuke from orbit, it's the only way to be sure!
@ the spectacularly refined chap
My statement is indeed a bit broad (and to generalize is to be an idiot). I was talking about when there is a bottleneck. If there is no bottleneck, there is no need to throw resources at it, hardware or software. The examples I gave are cases with severe bottlenecks.
In your example of the one-off job you are actually also thinking in terms of algorithmics: which one is simpler to implement (and therefore easier to get right). That is why for one-off jobs or experiments I like to use scripting languages (MatLab most of all for my work). Only when heavy lifting is needed (and we have established firmly what we want to compute) do I go for C(++).
You are of course right that there is always a balance to be had between implementation time and total CPU time used. In the very old days CPU time was costly, software development and maintenance time was comparatively low, because code was comparatively compact. Now CPU time is cheap as chips, but code development and maintenance is not, what with the dramatically increased complexity and interconnectedness.
Nowadays, the farmer first glues on some horns and sells it to the abbatoir as a cow.
You haven't heard of the reverse boast "only by throwing software at it" because of a very simple fact: If I can get more performance out of the same hardware, by designing an O(N) algorithm to replace an O(N^2) I am being smart. Throwing more hardware at a problem when a better algorithmic solution exists is stupid.
I have seen people use weeks of wall-clock time on a 512 core segment of a big machine, simply because their code was bad. My colleague coded the thing properly in C++ and had the code running on his desktop and finishing in a few minutes (O(2^N) vs O(N log N) if I recall correctly). Only throwing hardware at a problem is often wrong. Thinking about better algorithms is never a bad idea.
Once you have really thought about the algorithmics, then you can start throwing more hardware at it (and once you do that, you must rethink the algorithmics again, especially when doing parallel stuff). So in our massive image processing stuff (Gpixel and Tpixel), we first minimize communication and disk-access overhead, and then move to SSD or Fusion-IO stuff.
"The coating is "invisible" and it can be applied to screens and lenses without causing an optical effect."
That is a curious claim (I am being politic about things, just this once), unless the coating has an index of refraction of 1.0 (unlikely) and/or the coating is thinner than a very small fraction of the wavelength of light (some tens of nanometers at most I would guess). I suppose it could be integrated into the design of an anti-reflection coating, but just spraying it on afterwards will change the anti-reflection properties of the coating in general.
When people "explain" finance to me, I always refer to Going Postal. At the end of that book, financiers enter the fray. There is a brilliant passage which reads (approximately):
And they saved the city with gold more easily than any hero could have with steel. .... But it was not so much gold, or even the promise of gold, but more the dream that gold would be there at the end of the rainbow. Provided you did not go and look, of course. And that is called Finance.
You are a wise man, Terry Pratchett.

The old adage:
Nothing is foolproof for a sufficiently talented fool
still holds true
If the flapping of the proverbial butterfly wing has an impact of the weather, how come scientists could claim with a straight face that extracting several tera-Watts of power from the climate system will have no effect?
This scientist seems to be asking that self-same question.
This does not mean I am against wind power, I just think we should not blithely assume it does not impact climate in some way.
And of course, as Mustrum Ridcully would say, lets find those bloody butterflies that are causing all these storms

is for the clouds to sod off and let me see the comet C/2011 L4 PanStarrs in March (and comet C/2012 S1 ISON in November and December).
I do not know why I have had such a dismal run of lousy weather preventing me from spending more than a single night per month watching the stars (or indeed whether this is exceptional), I just want some clear skies!!

Wowbagger the Infinitely Prolonged is not in control of Curiosity. Otherwise he would use that punch to write a very rude word indeed (like Belgium)

Door handle? Also looks like the flushing handle in our toilet. If Curiosity pulls it, it might find the resulting evidence of water overwhelming
It is important! I am very fortunate to have just about the best water possible coming out of the tap.
Should that last line not be
Basic work version:
1. Take one wire-mesh tea-strainer spoon, and insert one good teaspoon of Keemun Black tea (Twinings Prince of Wales at a pinch).
2. Nuke water in big mug in industrial-strength microwave oven until it really boils
3. Add tea-strainer spoon.
4. Infuse as long as desired, or alternatively forget about it whilst coding and drink arbitrarily strong
4b) add milk and sugar if you must
Keemun black tea is very dark by nature, and never turns bitter, so forgetting to remove the tea only makes it stronger, but never renders it undrinkable.
On the road version:
replace tea strainer egg by Twinings Prince of Wales tea bags
Working in region with hard water:
Replace Keemun Black by good quality Assam and keep infusion time down. Assam takes hard water better than most

I have written well-structured programmes in assembler.
Whether either of the above is what I would want to do is another matter entirely. This is not a matter of snobbery, it is a matter of practicality. Scripting-based languages are very valuable for quick prototyping, or for portability, when top performance is not required (and JIT compilers go quite a long way to address performance issues). However, C and C++ are still my preferred tools, for development of high-performance code and will remain so for the foreseeable future.
