Off-axis in this context means outside the centre of the field of view of the instrument. Raw brightness data from many instruments need correction for contamination from nearby bright sources.

Re: That could mean a VERY bright supernova in visible light
I do not doubt that (in the words of sir Patrick Moore) this will have "all the crackpots crawling out of the woodwork". A type 1a in M31 would be about magnitude 5, but that would not cause a GRB-like event. I would expect this to be brighter (although much depends on extinction by dust)
That could mean a VERY bright supernova in visible light
Naked eye most likely. I'll be getting out the bins the moment the clouds clear (not likely at the moment), but supernovae last quite a while, so we should get to see it.

Re: Print dialogs
Or printers that do not refuse to print a black and white document just because the yellow ink has run out (again!). Funnily enough, some Linux printer drivers will allow B&W printing, whereas the windows version won't
Wonderful footage and images

You need to realise that 1 PB/s is 0.02% of what is detected. 99.8 or so % is discarded on detectors "boards" already, before it hits the first cable.
True, as a scientist you do not like throwing away anything, but with projects like LOFAR, SKA, and the like there is little other option. One trick in the case of LHC-like is to store the detected tracks in a parametric way rather than storing every point that made up the track. That makes a big difference. Might we miss things? Certainly, can we store all the data for later reuse? Not at the moment.
You really want to be able to do both. Processing faster to get the information from the data and store every bit quickly.
They need faster data reduction methods. We are actually working on much faster processing methods to extract the information from the raw data, so the raw data need not all be stored before processing. They do use preprocessing methods for reducing storage now, but existing methods do not scale well, so for ever faster data rates better, lower complexity algorithms are needed.
Not that I would mind kit with the specs they want. I want that too. And not to run Crysis!
I would let them listen to an endless tape with Marvin's autobiography
That should do it.

Re: Screen too small?
I actually rather like my 13" laptop (16:10 ratio, rather than 16:9). I am looking to replace it by a 13-14", no bigger. I am also very happy with my 10" ASUS transformer pad. That seems to be a MUCH better format for a tablet/laptoplet(or notebooklet) than this offering from MS, and gives me 15-16 hours of use (with less grunt, but I get that from my laptop. I do not mind having two or three devices, but maybe I am weird (i.e. not the category the marketeers are interested in)
Nice one again
Had not heard of this one. Very interesting read. Looking forward to the rest of the series

Re: What happens-
ArXiv is an example. Some journals do not allow you to publish with them if it has been released previously (even some bone-headed reviewers have difficulty with it), but many just see it as an "author accepted" form that is OK.
Copyright transfer forms come in different forms
When you publish with any scientific publisher you almost always have to sign a copyright transfer agreement. Many publishers simply use this as a means to clear themselves of copyright infringement charges, because you have to declare that the material is your own, and you have the right to sign over the copyright to them. Any extraneous material must be covered with a separate permission from the holders (which is never a problem, because the holders are only too happy that their material is being used, and that therefore they are cited).
Some publishers also want exclusive rights to publication, although all I know allow you to use your own work freely in non-commercial publications like e.g. a PhD thesis. Springer in its Lecture Notes in Computer Science requests you not to put your material on-line until one year after publication. It is not a prohibition, but since they ask nicely I tend to comply. IEEE allows you to post your material provided you show a clear copyright statement and state that the material is only provided for quick dissemination of scientific results for research and educational purposes, but not for any commercial use. This is entirely reasonable.
What the ASCE is doing seems a bit harsh, but the authors must read what they are signing. A colleague of mine crosses out any condition he does not like, initials the changes, signs the forms, and sends it in. He has never been challenged on these changes. I suggest all authors in ASCE publications follow that example.
Alternatively, you can publish in open access journals (or use the open access scheme of some journals with hybrid publishing format). Somewhat more expensive, but compared to the cost of doing the research itself it is nothing. You then simply link to the version on the journal's website and everybody can access it.
Re: Star Trek Replicators
The only downside of a replicator based on this mechanism is the formation of an anti-hamburger together with your hamburger. It may be a balanced diet, in a manner of speaking, but could lead to explosive indigestion to which the phrase "blast radius" would seem to small (swamp dragons would be jealous)

@ magickmark Re: No way near Homeopathic standards..
Coffee went everywhere when I read this "In quantum parlance, the "wave function" of the particle is said to "collapse" into a specific state (or flask) due to the act of observing. Incidentally, this is why cats resent people staring at them: the constant collapse of their wave function is a strain on their delicate senses". Worthy of Terry Pratchett or Douglas Adams.
WAY too much honour, you are making me blush
I might have a spare keyboard somewhere that I could send you
Re: No way near Homeopathic standards..
I wonder whether believers in homeopathy ever worry about the "memory of water" theory. It would certainly worry me, if I believed in it, because one of water's persistent memories must be being piss at many times during its existence.
I once wrote a paper on a quantum mechanical theory homeopathy. It got accepted in Annals of Improbable research. A preprint is here.
I can't do that for you, Alistair!
As HAL would say, or as Sirius Cybernetics would have it "Share and Enjoy!!", which does sound better than "Go stick your head in a pig!" but amounts to much the same.
This is my problem with several LaTeX offerings available for Android. All the ones I know require you to be online to actually compile the LaTeX source. Not easy (or affordable if available) somewhere outback in Uganda or the like.
Very nice read

Re: nagative altitudes
Even if the system was designed with a limited altitude range in mind, it still should be able to cope with input outside that range, e.g. by flagging an error in the input. My very first job as a programmer was to write a (half) decent UI for a DOS image processing package written mostly in Pascal. The previous programmer's effort used READ and READLN to get floating point values from the (mainly Dutch) users, which resulted in frequent crashes when users entered 0,23 instead of 0.23. I wrote a simple parser that only assumed it was getting a string of characters, tried to parse it, and flagged syntax and other errors to the user. Not rocket science, but simply going back to basics: does the string of characters entered as input meet the preconditions of the code that is going to use that data, if so, use it, if not, flag an error. This very basic approach ensured that medics could use the program without swearing at the computer several times each day.

Re: 16-page document I was working on last night won’t fit onto a floppy
Still got an 8" floppy lying around somewhere; one from Digital with CP/M 2.0 on it. 128kB capacity, WOW!
And yes, I still have an Iomega Zip drive somewhere.
One might well argue the USPTO has negative credibility.
Re: What needs to happen
I have yet to see patents so patently absurd awarded in the Netherlands or indeed the EU. I have one patent to my name, and the process appeared to be quite thorough. There may certainly be the odd one that slipped through (would love to see one), but not the spate of silliness coming out of the USPTO.
Note that the USPTO gets funded based on how many patents it awards not how many it processes. That is a perverse incentive if ever there was one.
That's not force feedback, proper force feedback is when the button punches you in the face when it thinks you have punched the wrong button! That'll teach ya!

Sure, no worries! I have had alligator on pizza (seriously) in Quebec City which was very nice, and sheep's brain (rarely used, always fresh) in Indonesia, so bollock pie sounds fine to me
Great read over breakfast
It seems to me
that quite a bit of global warming is clearly anthropogenic. It is all the hot air emanating from politicians and commentards alike. Most models fail to take that into account
On a serious note, I do not know (i.e. with 100.0000% scientific certainty) whether global warming or climate change is anthropogenic or not. Climate has changed a lot over earth's history, and CO2 levels are quite low at the moment, as compared to the mesozoic era AFAIK. It is also rather cold compared to e.g. the Jurassic. That suited a bunch of big lizards (OK, not really lizards), but not our current society, which has adapted to the current climate. Climate change may therefore disrupt our cosy lifestyle. To me it does not matter so much whether we are to blame. It is more important to see how we can get by, using fewer non-renewable resources, and how we can deal with a potential crisis, preferably without bloodshed. Mankind's performance in the latter case is not stellar, I agree, but maybe we can work things out this time.
Just my tuppence

That's a relief, I thought it might be "the one that must not be named"
I think it is wrong to hack pages (freedom of speech and all that), and linking the LGBT community to this honourable gentleman (phrase used without prejudice) might seriously offend members of said LGBT community.
Besides, the honourable gentleman (phrase used without prejudice) is much better at making a fool of himself than any parody could ever manage.
Re: So to get the job
But they don't have the resumé that was hidden in a locked filing cabinet stuck in a disused lavatory with a sign on the door saying "Beware of the Leopard", and that might (or might not be) the correct one.
Besides, if they know so much about everybody, they already know who is perfect for the job, don't they?

Ooh, that bring back memories. Tuscan food (all I tried last summer) takes a lot of beating. Having said that, I had some really nice Shiraz/Syrah wines last time I was in California. Some excellent food too. Not all food in the US is fast or fattening.
Darn, hungry now!
