Very interesting data set. I might draw up some MSc thesis projects or student projects for the Computer Vision course I teach, developing methods to efficiently search for anomalies in those data. Much better than letting them use some toy data set. Not sure anything of note can be found, but at least there is some chance we can contribute a little

Alternatively, lack of sleep could be to blame. I recall Marvin's lullaby:

My thoughts exactly. Digital watermarks are your friend here. Besides, AI may also be used to find the original, untampered footage, using content-based video retrieval, if said original footage is publicly available

Very interesting. More of a starlet than a star, but it does further constrain the border between red and brown dwarfs. I wonder if that boundary is influenced by helium content or metallicity. It is bound to, I suppose, given that the CNO cycle will depend on carbon, nitrogen, and oxygen (all metals to astronomers) abundances
Great boffinry. Looking forward to the results

Re: "Why would anyone need two graphics cards?"
Precisely. GPUs are great for SIMD-like parallelism, but it can be very difficult to harness when the task at hand does not allow such parallelism. In those cases, fewer, more complex and more independent compute cores can do a better job. Horses for courses, as ever. Many compute loads show a mixture of these SIMD and MIMD type parallel tasks, and for those the key factor in current designs is the fact that GPU and CPU memory is generally separate, and the speed of the bus linking the two is too low.
So, yes, GPUs are here to stay, but my (multi-core) CPU has this little piece of cardboard saying "I aten't dead!", and I think that is true.
The only reason I didn't spit tea all over the keyboard is that I had just finished my cup (an important precaution whenever I read the latest BOFH episode)
I can just imagine the response from the EDL and the like

It is not the amounts of data that matter, it is the labelling
Copious amounts of data are easy to get, rather harder to turn into information. In order to train most AI or ML systems you need copious data with a reliable ground truth. The latter is very, very hard to come by, and requires lots of very, very careful, and usually dull work in labelling data items as belonging to different classes. If your ground truth on which you train you method is suspect, you will end up with over-fitting problems, because the ML/AI method with faithfully try to reproduce erroneous human decisions. For deep learning methods like convolutional neural networks (CNNs) to yield their (often impressive) results, you need hundreds of thousands, or preferably millions of accurately labelled data items. CNNs have been around fr quite a long time, but only the advent of large, labelled databases of images and the like made the methodology take off. labelling hundreds of thousands of data items automatically would be ideal, but isn't always possible. Usually some poor sods has to do lots and lots of unglamorous work.
Apart from these problems (which are daunting enough), there is the problem of all the parameter choices (learning rates, numbers and type of layers in deep networks, etc) to get right
Re: Missing the point
Besides, what you learn in theory during lectures is not always what happens in reality. Modern HPC architectures are complex beast, far more complex than the Cray J932 on which I did my first serious HPC work: that was a shared memory set-up with no processor caches, and 32 identical vector processing CPUs. Predicting what is would do on different workloads was hard enough, but it is much harder with the current mix of multi-core CPU, GPU, and all manner of buses and caches working at different speeds that make up a modern cluster.
And anyway, this kind of competition is just fun!
Let's hope they do find it this time

Re: Well given that said columns are basically a vacuum
Interesting thought, which raises the question whether the column is vacuum, or merely vacuous? I would suggest the latter, as a true vacuum is so full of bovine excrement, which would exert a noticeable drag force on any sheep
Wouldn't Katie Hopkins' "thoughts" be anti-thoughts, so we have to look at anti-protons? (and yes, those have the (positive) same mass as protons, but it's the thought that counts)
Alternatively, given the often self-contradictory nature of what passes for thoughts in her case, some particle that is its own antiparticle (a Majorana fermion) would be suitable. As the most probable candidate for such a particle is the neutrino, which has near zero mass, this might be ideal
Isn't there a risk ...
that when we find out exactly what all these constants are, the universe will instantly be replaced by something even more bizarrely inexplicable (maybe this has already happened)

I think she operates on the principle expounded in one of Murphy's Laws:
It is immoral to let suckers keep their money
Either that or she actually believes that bovine excrement, in which case she sadly perpetuates the stereotype of the dumb blond (and I know plenty of highly intelligent blonds to know it is nothing but a stereotype)
I see Simon follows the Lord Vetinari school of committology: "What the Iron Maiden was to stupid tyrants, the committee was to Lord Vetinari; it was only slightly more expensive, far less messy, considerably more efficient and, best of all, you had to force people to climb inside the Iron Maiden"

Just a little mathematics
1,000,000 AU is about 4.8 parsec. At this distance, a M-type dwarf like Sholz's star which has an absolute magnitude of 19.4 would have a visual magnitude of 17.8, well beyond my 8" SCT. Even when Scholz's star passed at 0.8 ly, it would be a puny mag 11.3 star, roughly 250x to faint to see with the naked eye. There are some very, very faint stars out there. In fact, they outnumber the stars of the sun's brightness or brighter by a huge margin.
It is well known that although many stars form in open clusters, these drift apart, mainly due to gravitational disruption by other objects passing by in the fairly dense galactic plane. NGC 188 (also known as Caldwell 1) is an exception, in that it is a very old open cluster, which probably wasn't disrupted, because it is some way away from the dense traffic in the plane. It is therefore easy to imagine that stars forming as a wide binary system could be disrupted, and the two would ultimately drift apart.

I remember following the progress of all the Pioneer, Viking and Voyager probes
They were inspirational to me as a kid, and worthy follow-ups to the Apollo project. Seeing Voyager still ticking over, still sending back a trickle of data is awesome! Pints all round for all who made this possible
Somehow, whenever I see an image of this aircraft in any article, my instant thought is: "What's wrong now?" or alternatively "Not again!"
Can't think why.
Big thumbs up to the boffins involved!
