"My physics teacher was brilliant"
Mine worked on the Manchester 'baby' before becoming a teacher.
"and nobody will give you an insurance for 6 months abroad "
Nonsense. My motorhome has exactly that and it's the standard policy.
"France is by far the worst country in Europe to travel through. Idiotic junction layout, nobody following rules, horrid tolled motorways"
Many european countries have tolls, junctions are fairly standard, autoroutes although having tolls are mostly empty except at peak season. I drove back from Switzerland on 29/30th July. On the A26 between Troyes and the A4 (~60 miles) at morning peak period I saw ~20 cars/trucks on 'my' side of the motorway, on the A26 towards Calais things got busier with maybe 3 vehicles a mile density.
I admit the farmers, ferry workers and indeed migrants are a nuisance but the only delay on the journey was the UK Border Force at Calais using just 3 booths out of ~12 so what little traffic there was had to queue for 30 mins.
"This seems to be the case in the South anyway , which is the area I know best."
And everywhere else in France - I've driven more than half the motorways. The only places I can remember a manned toll is at the big bridges like Pont Normandie or the Millaud viaduct . Most exits (as opposed to end of sections) are fully automatic although there must be a person around to sort out problems. As I said earlier I can't recall having to pay a person for years. There may well be some manned tolls but they've been rapidly replacing them in recent years
I regularly drive from Dover ( leave hotel ~2:15) catch a ferry and drive to Saas-Fee in Switzerland arriving by mid-afternoon. Especially if done on a Sunday it's an easy drive of ~550 miles. ~ 470 miles are motorway - I enjoy it and I'm 64.
BTW comments about tolls. In my experience most French tolls are automatic, credit card devices - I've certainly not handed money to a real person for years and I drive ~4000-5000 miles a year in France.
"while a normal distribution isn't necessarily a bad assumption, it is still an assumption."
Quite. The number of times I've argued with HR people on just that point.
"Was hoping they where going to something clever with the vacuum of space to do the distillation."
You don't need vacuum to distil such a low-boiling mix. If you did use one it would have to be relatively weak and you'd need very cold condensing surfaces to avoid losing it all.
What "high-dimensional molecular structure consisting of water,....." is supposed to mean I can't imagine !
"A single cargo ship can pollute as much as 50 million cars."
That's sulfur pollution - v.nasty but just one pollutant.
From your own ref.
The International Maritime Organization (IMO) estimates that Carbon dioxide emissions from shipping were equal to 2.7% of the global human-made emissions in 2007 and expects them to rise by as much as 2 to 3 times by 2050 if no action is taken
"1. Power plants are more efficient that car engines, the pollutey far less per unit."
Official US figures for thermal electricity generation put the average efficiency at ~~ 35% which is ~similar to diesel cars.
I think combined plants that produce district heating etc. are much better but relatively rare
""Reportedly the 15 largest ships in the world combined emit more air pollution than all the cars on Earth combined."
That figure seems to be the amount of sulfur emitted. Not other pollutants AFAIK. Note most land-based fuels are now low-sulfur
(Sulfur not sulphur because I'm a chemist and that's the way we spell it now - not saying I agree)
"Too right - on this side of the pond (UK) it used to be 1,000,000,000,000!"

"Looks interesting but you need to know what you want before you make the distro image."
It's certainly not for the first time user but is truly an excellent resource.
"Excellent - where do I download a good selection of packages in DVD image form?"
http://software.opensuse.org/132/en - Download DVD will get you most common packages in iso form for 1 bootable DVD
https://en.opensuse.org/Package_repositories gives links to download lots of official and other repositories that you can install on a HD/USB stick or burn to DVD ( why DVD in this day and age) or more usually instal on-line using YAST package manager
They warn :
If you have enough disk space, you can also download a repository snapshot, but be advised that this can take up to 20Gb or even more.
"I will, of course explain that NVidia graphics kit has to be binned"
Strange that mine works then including video acceleration using vdpau admittedly with the NVidia binaries. Not had a WiFi problem for ~10 years and I've got all sorts of kit.
Must mention too the excellent Studio service that lets you build an entire distro to your own requirements.
"To my knowledge, Debian is the only distro that caters for offline installation of a significant selection of desktop software in this way. I'd be delighted to hear of alternatives."
OpenSUSE repositories can be almost anything including CDs, DVDs, Hard drives, local iso images, UBS directories/images/isos as well as lots of networked sources.
"No meniscus in dry measurement, just scoop, swipe & dump, so no worries there."
Very sorry jake - being teetotal (I wish) I assumed dry furikake was a cocktail hence a liquid.
Just use a 0.15625ml jug (brimmed - depending on what sort of meniscus dry furikake has)
"Is it sad that I remembered my favourite hardware register, 0xdff058, almost quarter of a century later without having to google?"
Don't worry about it - I can still remember some 6809 op-codes even though it had thousands of them.
( I too remember my A1000 with affection even though compiling Lattice C was a disk swapping operation until I got a hard drive)
"If you could do it at a continuous 1 to 2G acceleration, then it'd subjectively be a relatively short trip."
If, as you say, you could develop the propulsion the occupants might well experience a short trip but for the ones here waiting for the information it would still be 2800 years.
" but one in particular was the ability to click on a chart, and move intersection lines into positions on the curves."
"The lines were not specifically associated with the chart."
I don't understand what you mean by this. Surely a line not associated with a chart is just a line why would clicking on a chart enable you to move a independent line ?
Just playing around with this a line can be drawn on a chart that seems to be fixed to the chart if it's drawn during the definition of a chart from Insert-Object Chart.
If you define a data set and click the chart icon then an independent line can be drawn later that can be moved around.
"I have found that my own Linux boxes are not vulnerable,"
Same here and for multiple reasons. Some due to the default settings and some due to my sshd configuration/firewall/router firewall.
"However (seeing as Linux isn't really used on the desktop),"
Linux is really used on the desktop but not generally by casual computer users. A lot of scientists/engineers/academics use it for example. 1.6%, of course, is actually a very good number considering that many people have to get off their ars*s and install it themselves.
In answer to AC earlier (perhaps you could mention it to him !) the graphics performance is often the reason for using desktop Linux. I and many of my colleagues use if for hardware stereo 3D graphics for protein modeling. Rotating a large protein complete with all its bonds smoothly in 3D whilst running further computationally intensive modeling programs is about as demanding as it gets BTW.
"What are you talking about? Commercial software sells on its own merits. "
Agreed. For years I've been using seriously expensive protein modeling software that was written for Unix/SGI/Linux. The sort that needed a license server (or worse only had a few copies available via a token system )
"It's way too far out to be the ISS, that orbits at 250 miles. Looks more like a dodgy pixel on the camera's CCD."
Well it might be but as there seems to be quite a few more around the image I'd guess they were stars.
Yep -just altered the curves on the high res-image - space is full of e'm
"Does anyone know of a way to get some of these metrics?"
Is about:memory what you are looking for ?
Blimey - you must have quick reaction times ! Even this old dual-core, 2GB with on-board graphics switching tabs is 'blink and you'll miss it ' .
"I am thinking about moving over to Linux and I can't say that this article helped me at all."
My advice for what it's worth - get a few Live-CD/pen-drive distro - try them out (without needing to install) to check the hardware and UI. They'll run slowly but that's not the point at this stage.
For example http://software.opensuse.org/132/en and chose "Click here to display alternative versions" to get live-cd of KDE or Gnome versions
"The 2GB is needed to run Firefox. Regardless of desktop/WM/OS..."
That's total borax. Although this laptop has 8GB, my other machines have 2GB and indeed one is a 1.4GHz Celeron with 1GB. All of them run the latest Firefox on top of a full-fat OpenSUSE 13.1/2 KDE desktop. All run Firefox well. Currently this laptop is using 380MB for Firefox with 9 tabs open - the highest I've ever seen is ~800MB.
I can see that you'd need to be anonymous BTW
Thanks for that Will. I've been a long term user & advocat for Suse/OpenSUSE since V5. Excellent trouble-free distros
"I could never get into KDE myself and I never understood why Linux couldn't settle on one desktop"
I like KDE - if there was just one Linux desktop I'd want it to be KDE . So I'm happy that there are a number of both desktops and distro. esp as changing desktops is easy.
If you're arguing there should be an 'easy' distro with one well-supported desktop I might agree but multiple desktops and distros are one of the main strengths of GNU/Linux and I wouldn't want that to change at all. If people want to develop a distro then so be it.
"but if it was just the picture and manual appraisal, they would probably be less strict about the expression, background, glasses etc"
This not the first time ( or indeed 2nd or 3rd) I've taken our passport photos - most of the requirements as to quality/background etc were in place long before biometric passports but at least the photos in the passports were recognisable.
You're quite correct my wife's passport is due for renewal soon
"And again, it's not about people looking at the photo,"
Oh so you never go through borders where they don't have this equipment then ?
And BTW my wife's passport isn't biometric and the same poor quality applies.
"Does it matter??? Why be so vain about a passport photo???"
It's not a question of vanity - it's not easy in any kind of poor light or bright light to actually see the photo well enough to identify the individual - kind of the purpose of a passport. UK passport applications give all sorts of instructions about the quality, size & background of image required and then turn out an inferior product. (Unless all border officials have their eyesight modified !)
I spent quite a lot of time taking our passport photos and the resultant prints were nigh perfect - then the passports came back with absolutely awful reproductions - smaller and very low contrast. Wish I'd just used a machine
"Cannot wait to see the results of the flyby"

"Plus also it takes a fairly massive dose of it to do any sort of damage,"
~20 tablets over a few hours or less will do it esp. with a lower weight person or one with an already damaged liver. As the original article mentioned "a huge handful of ibuprofen and acetaminophen” it also appears to depend on the size of hand. I'm sure, in fact, that it was a colourful phrase rather than a measure but with some common drugs it really is too easy sometimes to treat them as relatively harmless
"Paracetamol is only intended for short term pain relief. It says so on very packet I've seen"
No it's often used for chronic pain like that of osteoarthritis. OTC bottles of all sorts of drugs are required to tell users that they should only use them for short period.
Paracetamol is relatively safe at normal usage levels but recent studies have suggested that chronic use at higher than recommended levels whilst not acutely toxic can in time lead to liver damage.
Just got to point out that an overdose of acetaminophen ( paracetamol) is VERY dangerous and will often prove fatal. I hope everyone knows this but ...
"t'was a time when 512 bytes was over-indulgent luxury."
Certainly I started on 256 bytes programmed via a hex keypad and not on a microcontroller either (SC/MP on Science of Cambridge MK14)
"So is this driver code hard-baked into the kernel? "
No. It's usually all loadable modules - all of which you may have on your drive for convenience or not
"That's also some claim when Germany is in such tight electrical straits they've had to buy a sizable chunk of their electricity from France lately."
I've mentioned here before that a comprehensive analysis of Germany's electricity stats (2014) can be found at :
Page 6 ;- first 11 months of 2014 total generated electricity ~470 TWh
46% coal, 9% wind, 7% solar,
"None of which are actually functioning today"
AFAIK the replica of the Manchester 'Baby' is around and ran in 1998. I was taught physics by a chapvwho worked on the original and had a photo of himself, stripped to the waist, working in basement surrounded by racking
" "throwing away" data pre-determined as "uninteresting" for a long while yet. Probably forever"
Probably !. It'd be nice to know how much this huge data stream has already been processed (FPGAs, heuristics etc) at the experiment . Anyone know ?
"As I see it, the good of systemd is that I can reboot in a small number of seconds, and the bad is that I seem to have to do it at least ten times as often, for something like a wash"
Using OpenSUSE I reboot hardly ever and only switch off when I'm traveling. Updates arrive regularly and systemd seems to restart any daemons that have been updated.
"Moving on, I'm sure you can improve on my answer, if you care to. If the structural strength of graphene is currently realisable (no pun intended), why not ditch the copper entirely and go with a graphene conductor?"
The simple answer is that I don't know
"Perhaps because graphene is one atom thick and has no structural strength?"
Perhaps you'd like to reconsider that rash statement. Just Google it
"f you consider the graphene not as a sheet of carbon, but two layers of hydrogen stabilised by a lattice of carbon + electron soup ( extremely simplified, of course)."
"To migrate to the silicon any copper atom would have to react with the H of the graphene first.."
Sorry I should have noticed this sooner but I've been busy today. I'm afraid you are under a misapprehension - graphene doesn't have any hydrogen attached to it - it's pure carbon sp2 hybridized. so planar like benzene but with all bonds carbon-carbon
"So this is Graphene Oxide ..."
However graphene oxide != graphene
In any case the water permeability seems to be along the axis of pairs o sheets
