At least they didn't name their brand

Fascinating behind-the-scenes look! Great thanks to Dr. Hunt and El Reg! That brought back so many fond memories from Apollo, Mariner, Viking, Pioneer, and of course Voyager. It was the people that made this possible that got me into astronomy, and indirectly (through image processing) computer science.
We have a group of three compute servers (64-core Opteron machines) that three groups ordered together. The fluid dynamics group's one is called Poseidon, the AI group's one is called Pallas, and mine is dubbed Zeus, king of gods, as it is the most expensive one, with 512 GB instead of 256 GB RAM. Fairly boring, compared to some of the schemes mentioned.
I also rather liked the names of various Beowulf clusters in the past, like Hrothgar, and other figures from that epic poem.I suggested calling a cluster at our university Grendel, but that didn't take off, for some reason.
Where 1/3rd - 1/5th of all statements need to be polite (" PLEASE DO", "PLEASE DO NOT"), etc. I always found the COME FROM (time-reversed GOTO) statement in later versions a stroke of genius.
Next time a student annoys me, I might set his or her next programming exercise in INTERCAL. Evil? Certainly! Fun? Absolutely!!
I have been observing the sun for years, and I have rarely seen the sun so quiet, even in Hydrogen alpha light. There were some nice prominences visible on the north-eastern limb yesterday, but otherwise all was quiet. in white light, it is just a dull disk, as my most recent solar image in white light shows. Things are little better in Calcium-K light.
I remember pointing out Mars to my kids when they were quite small. If they were impressed at seeing a planet, they were stunned when I told them two robot cars made on Earth were trundling around on that red speck in the sky.
Hats off (min's the grey Tilley) and big thumbs up for the engineers who built such amazing machines. I will raise a pint (or a tot of malt whisky) to Opportunity this evening.
I have recently noticed many of these guys introduce themselves by some very British sounding name (I had a "Mark Williams" recently) in a thick Indian accent. I am SOOO tempted to answer in an equally thick accent "this is Bill Gates speaking". I wonder whether I should use a thick Indian, Scottish or Aussie accent.
Choices, choices
"That's what happens when you let FORTRAN programmers build things"
Whereas Pascal programmers could simply choose which one would be first, as in
CONST First = 42, Last = 43;
VAR Voyager : ARRAY [First .. Last] OF SPACEPROBE ;
and given that there are just 2 Voyagers, they might have gone for Voyager FALSE, to be followed by Voyager TRUE (or actually Voyager[FALSE] and Voyager[TRUE]), which would have been really, really WRONG
I'll get me coat. The one with Jensen and Wirth's "Pascal User Manual and Report" in the pocket. please
Utterly indifferent indeed. Whenever you shake your fist at the universe, shouting "It's not fair!!" the only answer you can expect is "So?" although no answer will be forthcoming, of course. I tend to think that if a god exists it can either be omnipotent or benevolent, but not both at the same time, given the indifference of the universe to all we hold dear on our little blue dot. I therefore cannot be bothered to believe in any of that kind of mythology, although creation myths are very interesting, not because of what they say about cosmology, but what they say about people, as Terry Pratchett put it so eloquently.
A little fatherly advice to the younger nerds out there: Dancing is a good workout, good fun, and of course a chance to meet the ladies. You might find it unnerving at first, but if you start at the beginner level (well, obviously you do) the ladies in question are just as inexperienced as you are, so don't worry about not being good at dancing. I have been doing it for more than 25 years (Ballroom and Latin, Salsa), and it is a fun way of staying fit. Of course it is still a way of meeting ladies. And yes, I still find it somewhat unnerving to ask a lady to dance with me, but judging by the smiles I get, they appear to be having fun dancing with me (and apparently not at my expense), and having fun is the whole point of dancing.
BTW, it is never too late to start dance classes

A whiteboard is an essential software development tool! It requires no internet connection, doesn't use power, is multi-user, multi-tasking, and zero start-up time. Bliss.
When we had to move to a new building, I (successfully) insisted that my old, really big whiteboard be transferred to my new office, even though they claimed it couldn't be done. It was too heavy for the idiotic wire-suspension system the architect insisted on using, and we were not allowed to attach anything directly to walls (architect's orders, again). After some delays, my whiteboard magically attached itself to the wall, and there it still is, helping me design new (parallel) algorithms for image analysis, amongst many other tasks.
Cycling through, or even near a park in my home town became quite risky at the height of the craze, as I frequently had to jam my breaks in order to avoid some idiot who stepped out onto the street or on the bicycle lane. Now I will have to play dodge ball on my bike as well. If one hits me I will give the owner's phone a reprogramming it will never forget (with a large axe, for preference)
Don't forget: requirements elicitation will only just have started IF you are lucky, and even such requirements as are known will be shifting continuously.
On day one, I would just start writing that report saying we are up excrement creek without a means of propulsion, or indeed floatation, and those handy logs we spotted hopefully just now, have a suspicious number of teeth, and are closing in. After that, see to it that you get airlifted out of there quickly
That might not work at all. A research lab or university might hold patents that they license out to others, rather than selling them to manufacturers. These institutes would be penalised under your proposal, whereas they are not acting like your regular patent troll. Indeed, it is not the place of universities or research institutes to compete in the market, but they can earn extra income from licensing. Money earned this way can be put back into research and innovation. The main problem seems to be the broken patent system in the US, as patent trolls seem to be a rare species elsewhere.
This is not quite correct. It is reasonable (from an evolutionary standpoint) to assume that the very first thing we could call life (like the auto-catalytic cycles proposed by Stuart Kaufman), we less efficient at replicating themselves, using available resources like food and energy, or even simply maintaining their own structure than later, more advanced cells. Once these more advanced life forms had evolved from more primitive ancestors, they most likely spread exponentially, and would out-compete any new life-form trying to start from scratch. There may have been many other "starts" that were obliterated by our very, very distant ancestors, simply because they used resources more efficiently. There may also have been many starts before the successful one that lead to us, that somehow got wiped out by some disaster. Alternatively (more or less like the much later merger of proto-eukaryote cells with prokaryote, in which case the latter turned into organelles such as mitochondriae and chloroplasts within eukaryote cells), the new forms might have been assimilated within the older ones.
Let us assume that on a planet the size of earth, under the right conditions you could have a "new start" once every million years (and following Kaufman's reasoning, that is a pessimistic estimate). If we have a successful start, on average, it will have a million years of evolution before any competing "new start" arrives on the scene. That is a very long head start for the first comer.
In conclusion, there may have been multiple starts, but these multiple starts either got assimilated with the first successful one, or got out-competed.
That graph is highly suspicious. If a student presented results like that to me in a report, I would certainly give them a thorough grilling, and probably report them to the board of examiners. It certainly looks like data were "massaged" (ineptly at that). Just from the graph I cannot be sure, but I would be highly suspicious. As I teach students in our scientific ethics lessons: the two worst things in science are plagiarism and manipulating data. Plagiarism is usually quite easy to detect nowadays, so it is just stupid to do it. Fabricating, or otherwise altering data is inexcusable, as it can be near impossible to detect. Both plagiarism and data manipulation are reasons for dismissal.
That is a real risk. As has been said before: Scientific discoveries usually start with "hey, that's odd" rather than "eureka!"
More importantly, will we be able to stand the intolerable air of smugness these AI lab assistants generate whenever they have performed an experiment well?

Noble idea, won't stop the odd evil genius in his volcano lair, or any government bent on causing trouble, or just some run-of-the-mill idiot who wondered what would happen if you pressed this button (and not the one that causes a little sign saying "please do not press this button again" to light up).
which is reassuring. It might well be useful. I have given the paper a very quick read, and the idea of using statistical reasoning seems and learning seems reasonable. I would like to see how it performs on seriously big astronomical images compared to other advanced denoising methods (and goodness knows there are many of them). If it does the job efficiently, I will be happy, if others outperform it, so be it.
There are some interesting machines coming out these days, which would allow me to have a mobile workstation that can do some serious heavy lifting image-processing-wise (gigapixel images and 100s of GB of video and the like), without me needing to do some serious heavy lifting. I could do this stuff remotely, but that would generally require a seriously quick internet connection. I routinely gather 250-300 GB of uncompressed 6Mpixel resolution video data, which I then reduce to a single 100+ Mpixel lunar image. It is doable on my current laptop, but it does take all night. Sending the data to another machine is not really an option, so having a much faster machine chew up the data would be great.
