Gullable, I agree is not in that dictionary, though it may be in Ultra-Complete Maximegalon Dictionary of Every Language Ever"
Quite easy through an 8" scope. My fourth supernova to date (seen, not discovered). There is another one in the constellation of Virgo, which I am still hoping to catch.
It's written in Murphy's Laws:
a) The chance of a demo crashing is an increasing function of the number of people watching
b) The chances of a demo running flawlessly is proportional to the inverse of the importance
I doubt this simulation will be the last word, but for now it explains the data quite well. Of course, the observational bias will also be there, but that does not mean the effects simulated do not exist. It does make the "habitable moon scenario" seen in star wars more likely. Whether they are inhabited by bear-like creature who using stone-age technology defeat an army equipped with technology as advanced as faster than light travel is another matter entirely (although the movie did show the physical disadvantages of walking tanks with a comparatively narrow spacing between the legs compared to the height of its centre of mass)
Amanfrommars, is that you?
And besides, a random appearing string of characters might be a program in Perl
Which would be "interesting" for the crew in their open cockpit.
It is exciting when people go after such a long-standing record.
Worst film nominations and nobody mentioned U571?
Most bad film I can ignore, and they will go away again. U571 is such an insult to what really happened in cracking enigma that it just gets my blood pressure up (and many others).
Look out for big yellow triangular thingies (technical term) in space.
I wonder how sir Humphrey would have managed to subvert it. Could have made for some interesting episodes.
The situation is a bit different from that of planets, as the notion of dwarf planet was introduced to cover cases like Pluto and the larger Kuiper-belt objects. The notion of a dwarf galaxy has been around much longer. Proper definitions help to avoid confusion.

Would find use on El Reg, I suppose
Yes, but do use El Reg approved units
More importantly, how do you submit a type N post?
I really want to, but on second thoughts, I cannot be bothered
" personally think that watching that shit would wind anybody up, male or female. I only have to hear the theme tune from A Certain Famous Soap to feel my blood pressure rising."
Absolutely! My wife frequently wonders why I leave the room when certain shows are on TV (not just soaps, "talent" (word used without prejudice) shows have an even more pronounced effect). I tend not to say I am looking for more fun things to do, like stapling my ears to a wall, or putting my hand in a meat grinder. Somehow, remarks like that do not go down well.
By improvements in (time) management?
Active regions on the sun (groups of sun spots) are numbered. This one happens to be 1429.
No aurora to see. Moonlight may have been the culprit, or maybe there was just nothing to see (apart from the Moon, Venus, Jupiter, and Mars)
I was accosted by evangelical Christians yesterday evening and was asked what I believed in. I pointed to Venus, Jupiter, and Mars in the sky stating that my Goddess of Love, Father of Gods, and God of war were all now visible in the sky, so who was I to doubt. They were genuinely shocked.
On the other hand, if I started out about the FSM they would probably know immediately I was pulling their leg (which I was of course), so suggesting belief in ancient gods is probably the better ploy.
I will test the 64 core 512GB single box (4U rack server) we are getting shortly (for processing large astronomical and remote sensing images rapidly). I will compare the cents per MFLOP/s to the figures here. We already know it will kick the backside of the 32 processor Cray SV1e we used to have performance wise, at less that 1% of the cost. I am really curious what the figures will be. Linpack has its limits of course, but it is still nice to know where you stand, even roughly.
But whenever I hear the name of these orbiters, I have an image of John Cleese as "Tim the Enchanter" from Monty Python and the Holy Grail. The way he bawled "GRRRAIL!!" in a Scottish accent at Graham Chapman as King Arthur is forever etched in my memory.
Maybe there will be some aurora activity.
Maybe they like enchiladas?

Isn't that when they release the iFool?
Sorry, couldn't resist

I'll get me coat.
But then I do not live in Blighty
I just got me a 2 Terabyte disk for picture backup, which should keep me in business for a while. I might put some stuff in cloud storage for cloud processing, or access when not at home, but I will certainly keep local backups.
Given the price of a NAS, you can store shed-loads at home for very little.
This is proven by the fact that the Delilah speech scrambler shown in the picture was called "portable".
By implication, we assume women were real women, and small furry creatures from alpha Centauri were real small furry creatures from alpha Centauri.
Could get messy if everyone could fire a minister, but I know we have all wanted to at times.
with FRICKIN' LASERS.
That'll show the rats!
Glare can cause a non-circular object to appear round quite easily.
Usually the brightest fireballs show up red and green N2 and O2 lines. A very bright one may show other traces, but it might have been difficult to get spectral readings on such a fast moving object.
The lot of them. Really interesting stuff is being made out there.
One caveat: Igors disapprove of near threshold computing:

Ah, now you are talking. Proper Bond movie with no fewer than 7 James Bonds (well, 6 and one Jimmy Bond).

Where they using procrastinators to get the filming done quickly?

I would have no problems remembering 5 digit or longer ones.
Regarding blacklisting, given that your bank knows your date of birth, surely they could forbid you to use a number derived from that date? That would not prevent you from using your wife's, or kids birthday, but those are not printed on your ID, as a rule, so at least some security is added.
or actually, not that cool (the moon, that is, not the science).
Many image processing tools are easily broken up into small loads. The tools we develop are so-called connected filters in which data from all parts of the image may influence all other parts. Often you want to avoid this, but e.g. for analysis of complete road networks, you cannot predict which parts need to communicate with which other parts. To cut communication overhead down you need comparatively coarse grained parallellism.
We have been able to device a scheme (which we are now implementing) which cuts down local memory requirements from O(N) to O(N/Np + sqrt(N)), with N the number of pixels and Np the number of processor nodes. Normally you just require O(N/Np) per node. Communication overhead can be dropped from O(N) to O(sqrt(N) log(N)). This has moved the problem from the impossible to the "possible, but you need a coarse-grained cluster."
Of course, the first (shared memory) parallel algorithm for this filters dates from 2008, so we still have much to learn. Other problems in science can also require global interaction between particles (gravity has infinite reach). A lot of work is done cutting communication down, but this is often at the expense of accuracy.
We are looking at terapixel scale image processing. One aim is compute the entire aerial photography data set of the Haiti earthquake for damage assessment. We aim to do this in a few hours. This can still be done at the multi gigaflop rates provided by decent size clusters. For the 2004 tsunami, we would need orders of magnitude more compute power to handle all measurements required (we are talking petapixel range). These are computations that cannot possibly wait. Though exaflop processing might not be needed yet, as image resolution increases, so do the data rates. Compute power will have to keep up. Real-time emergency response requires real-time processing of vast amounts of data. The size of each compute node of the EC2 and similar cloud systems is far too small for our purposes (we need to have at least 32 cores (preferably 64) cores per node and between 128 GB and 1 TB of RAM per node).
So, yes, I can see real-world, life and death applications for these kinds of compute powers. Other applications include large scale scientific simulations (think evolution of galaxies, or the cosmic web, but also earthquakes, ocean currents, or even the blood flow through a sizeable chunk of the vascular system).
it is "merely" liquid nitrogen (LiN) level. Not everyday, but not nearly as impractical as previous devices requiring liquid helium (LiHe) temperatures. Think of the Josephson switch, which was hailed as a breakthrough in high performance computing once. LiHe cooling requirements.
If we can build qubit devices based on this, the potential gains might outstrip the cost of LiN cooling.
