Re: Mixed lessons from history?
The story I heard was that the Russians bought one Nene engine (legally) and said, thank you very much, we will copy them, without bothering about licences, but I might well be wrong. Both stories are equally believable: A government cynically copying stuff developed elsewhere or an arms manufacturer cynically selling military gear to anybody with enough cash.
Re: Ever wondered if...
The nearest supernova remnant to you is you, but it goes a bit far to point to a distant (actually, close by on a cosmological scale) supernova in Messier 101 a year or two back and say (in a high pitched voice) MUMMY!!!, as I heard one amateur astronomer do at a star party.

Re: Its an interesting idea...
A problem with bigger stars is that they burn up much more quickly. They also output much more UV. Besides, smaller stars are far more numerous, so it does not make much sense to go for the big ones
Re:"If we did leave the solar system, where should we go?"
And when they find a perfect planet, somebody is bound to say:
Yeah, but you know how it is with travel destinations: they look all shiny in the brochure, but when you get there the landing strip is awful, the customs officers rude, the taxi driver rips you of and drives you to your hotel which hasn't even been built yet, the sand on the beach scorching hot, but the sea is freezing cold for some reason, and it's polluted, and the Germans have taken all the towels and deckchairs, the food is awful and the toilets wont flush, the next-door kids will making far too much noise and the disco next door means you can't sleep a wink!
We might just as well stay at home or go to Southend-on-Sea
Such people should be sent of on a B-Ark to a small blue-green planet at the unfashionable end of the western spiral arm of the galaxy.
Oh, hang on.....
Alternatively you could name your servers

Here they used Pallas, Zeus, and Poseidon. I got some blank stares from the CIT crowd (Philistines, the lot of them ;-) ) when I suggested Offler, Om, and Nuggan

Re: Interesting simulation
I have seen spiral arms develop in simulations of collisions of galaxies run by a colleague at the astronomy department, where they appear to be material structures. I must have a look at the paper later.
"The only similarity is that both rings are round!"
As J.R.R. Tolkien said when a (Swedish, I think) translator drew lengthy comparison with Wagner's "Ring des Nibelungen." I think the museum is hoping to ride on the popularity of the film to draw in visitors (can't blame them).
Magic rings abound in myths and legends, and Tolkien new many (Kalevala, Mabinogion, Edda, etc.), and inspiration has many sources. Also, in the Hobbit, the ring is simply a handy tool, and only in the LotR does it become sinister.
When I did astronomy at the Kapteyn Institute (in the 1980s), a similar theory floated about, which suggested the spiral arms are essentially a compression wave running through the gas and dust, triggering star formation in spiral patterns, and the hot, short-lived stars lit up the surrounding gas with their UV radiation. Shortly after the wave passed, the bright stars burnt up, and the amount of light decreased, without the total mass density changing much. The theory behind this simulation runs along a similar pattern, although in the 1980s simulating anything this big was impossible, of course.

Re: Kerbal Space Programme....
Nor does Goddard. He made a few contributions.
The thing we really need is an infinite improbability drive, so if anybody can give me a Bambleweeny 57 sub-meson brain hooked up to an atomic vector plotter, I will supply the cup of really hot tea and feed in the improbability of the infinite improbability drive.

I think many of us share the view that we should archive all plans from middle management (and indeed many government plans as well) in /dev/null. It can be done without any loss of real information
And rightly so!

Members of the Israeli Defense Forces?
Given that military service is compulsory for most Israelis (quite a few orthodox Jews are exempt, despite being very militant), and can be called up at any time as reservists, it might be quicker to list those Israelis not in the IDF.
Just my tuppence

Re: Wot no checksums?
Even the best error correcting codes fail in practice when the signal is drowned out by MASSIVE random noise output by the sun. It would be like trying to shout at somebody on the other side of a football pitch while Motörhead are doing a gig in between. I think you will find that quite tricky (this is why people text each other in the disco, instead of talking).
Now make the football pitch a few hundred million km across, and replace Motörhead's few ten's of kilowatts of power by 3.9x10^26 Watts, and you get the picture.

Re: Why do people put forward the idea that iPads are good for art?
My kids much prefer to get their hands (and everything else in a 5 furlong radius) dirty with REAL paint, or real clay, rather than using a screen (they also like that, but the real deal is more fun).
I also totally agree that a device on which you cannot programme, and which is not sergeant-Detritus-proof, is not a good tool for IT in the classroom.

None are so clearly upset ...
as those who repeatedly claim not to be upset.
Cool, seriously cool!
We live in such exciting times. I several algorithms which could benefit from much faster global access (and just more processing grunt, but that goes without saying). I do worry how to harness the power embedded in your typical GPU architecture. They do not seem to like data-driven processing order much. Scientifically, that is a challenge of course, not a problem.
I will join

You are all misunderstanding it. It a very cunning advert for LaTeX. If you adjust your monitor settings properly, the message "LaTeX RULES!!" can be made out in the background.

It could be the South Koreans doing it to fellow South Koreans they happen to dislike, and give them a excuse to attack North Korea with similar means. This suggests they are in the third stage of warfare according to Douglas Adams:
1. Retribution: I am going to kill you because you killed my brother
2. Anticipation: I am going to kill you because I killed your brother
3. Diplomacy: I am going to kill my brother and then kill you on the pretext that your brother did it.

Re: It is, ... absolutely awful
"On BBC News this morning they showed "her" in angry mode shouting "You're late! Where on earth are you?" in a way that I found really quite unnerving. I suspect anyone feeling a little harassed would not want one of these."
And anyway, isn't shouting at you that way the privilege the missus?

I do wonder if it would not be simpler to, you know, insert a camera into the phone, and, like, image or film the actual expression of the sender rather than simulate it, but perhaps that technology must first be developed
Can the software please add a sarcastic expression to the above statement?
It is of course handy if you want to send an insincere emotion, but that would of course be unethical, so nobody would do that

That might actually make me join in
For me fishing always seemed boring, unless when using the "nutting the salmon" technique proposed by Billy Connolly (it involves a crash helmet).
The speed of sound increases with the stiffness of the medium, and decreases with density. For an ideal gas stiffness depends on pressure, which depends of density and temperature. The net result is that the speed of sound increases with temperature. So low temperature leads to low speed of sound. High in the atmosphere, the temperature is low. However, at the altitude of satellites, things are probably more complicated, as ionizing radiation of the sun may heat molecules to 2,000 K or more (and ionize them, changing the properties of the dilute gas), depending on solar activity.
Some advanced reader (claim to) use IR light and the Doppler to detect moving blood under the skin. Those scanners are not fooled by these fake fingers. I gather some scanners even OKed photocopies of fingerprints
Re: NASA has found.....
Some sediments are actually deposited by wind. Plenty of that on Mars. Hydrocarbons would be interesting. Await yells of "There's oil in them there hills!!!", followed by a rush to get to the oil first
(and once found, wondering how on earth (Mars) they can ship it back to the nearest refinery)
I am given to wonder whether the odd results are real, or artefact of this new method. It would be really very cool if it works as flawlessly as claimed in this article. I will go and have a look at the actual paper to make up my mind.
Exactly, all stuff for the "Scientists Now Know" corner of Annals of Improbable Research, home of the Ig Nobel prizes (and the judges will be spoiled for choice (again)).
"Grasshopper" does instantly remind me of the Kung Fu series with David Carradine, however.
That says a lot about my age, I suppose
Nope! No blood on the floor here.
I just suggested it here, and various beverages got sprayed on the floor. A few tears of laughter were added shortly afterwards.
If our students want to learn COBOL, we point them to the library where there are a few books on COBOL. When they look blank, we tell them the library is the place with all the books and stuff.

Re: Proper programming language
Good points. This is one reason we went back from Java (still used by us for teaching OO) to C for our initial programming course. We find the students learn to understand what is going on better. Having to do your own malloc and free can be a pain, but learning what memory management actually is about is useful.
More importantly, I think it is important to teach the students programming rather than teaching them a programming language. The first is a way to think about solving problems, the second is a tool to achieve a result. You need to learn both of course. In terms of programming languages, the most important skill is to learn how to teach yourself a new one.
Another point is that there are two reasons to learn a new programming language:
1) because you want to work on a project written in that language
2) because you want to learn new ways of thinking about programming
If you have learnt to program in Pascal, learning C does not give you a fundamentally different way of approaching programming problems, but Haskell or Erlang will. A thoughtful discussion on this is found here.
It is also about pattern recognition
Indiscriminate adding of data makes finding any information hard. There is a real risk of drowning interesting patterns in noise. Data != Information
As I like to tell students (over and over again): Adding hay does not make finding needles easier
We do do some work on really big data (vast amount of image data from astronomy and remote sensing), but that data has lots of internal structure which helps finding stuff.
