"Foresight is cheaper than development "
As a Linux only user I might be devastated by this news except I don't use Met Office widget for Firefox anyway.
"but that involves at least one more click than usual" - er ? Bookmarks anyone ?
As for iPlayer - simples use get_iplayer instead
"how it would let water through but not helium "
It's not clear to me how the layers are orientated bu it looks as though the graphene sheets are stacked "vertically" |||||| so that the water has to move along between the sheets. If these have hydrophilic groups and have dimensions that just allows water to move through the spaces then other materials may well have problems as there will be a strong tendency for water to fill the spaces and repel any other molecules. In this situation the water will behave quite differently to bulk water - it'll be more like a sloppy ice where every water molecule that evaporates from the low humidity end will need to be replaced from the high end to maintain the energetics.
selectively allows H2O to pass
I guess it well might. Even chemistry is different with deuterium. The rates of reactions are generally slower and drugs with a hydrogen replaced by deuterium at a point of metabolism are usually metabolised significantly more slowly.
Re : After burning up on re-entry !
So some people think that a heat shield, steering mechanism and parachutes are going to be feasible for 20000 tonnes of iron ore or whatever
"a dynamic governor at moon base alpha"
To manage all the telephone sanitizers and hairdressers that'll be arriving soon after.
the article keeps banging on about mass difference e.g " live long enough to measure the positron’s mass" or "one such possibility – that matter and antimatter have different mass."
Now I'm just a chemist but ..
We know the mass of an electron - if the energy from electron/positron collision is not twice the equivalent of the electron mass then doesn't that give the answer directly ?
Any physicist care to comment ?
The other quote :"Cross-platform support is essential to avoid being locked into a particular technology.”
Like Office ?
If half a million Linux devices are activated every day
Sorry I find that a poor example - the data isn't "under one roof" and available to anyone on the CERN network.
The LHC is going to generate 15PB of data per year.
Their GRID computer :-
Number of machines: 14,972 processors with 64,623 cores running Linux
Some facts about storage capacity (November 2011):
Tape: 41 PB of data, including non LHC data. (Source)
Disk: 62K hard drives with a total capacity of 62660 TiB. RAID is used to increase redundancy and stability. (Source)
That sounds like quite big data
"I've noticed a trend of people my age and up (30+)"
I've noticed it too.
Maybe it's the fact that they have hardly been exposed to anything else.
When I think of the bare board micros , ROM Basic, .... Amiga, Forth, PC, Linux that I've been exposed to as an amateur let alone the terminal/mainframe, PDP11, VAX, Linux workstations and farms in my professional life I guess anyone 50+ has lived through a lot of changes.
"And I acquire another quick box "
Ditto but with OpenSuse on it
Definitely not Intel inside..
but otherwise I can't check as the waste bin in question is ~900 miles away at the mo.
May have been "Designed for WIndows XP" or some such nonsense.
last PC laptop I bought
I used the "Windows inside" sticker to adorn the lid of a waste bin
SGI Altix UV
It's SUSE or Red Hat Linux or Windows that are available.
From SGI's website
"SGI UV runs unmodified versions of SUSE Linux Enterprise Server as well as Red Hat Enterprise Linux. Microsoft Windows Server 2008 R2 is also supported across the product line"
Not found any mention of IRIX
"Your average software guy doesn't have hardware skills"
Maybe not but he will know what he would really like to do and can ask the hardware people to consider possible solutions - think of blitters and barrel shifters etc.
"As for toll roads"
Paying French motorway tolls is MUCH faster with a card, most people seem to be in the long queue for cash. No PIN needed just card in/out
"I use it rarely and pay it off as soon as possible"
As indeed do I by variable DD with the exception that I use it as much as possible because the CC company gives cash-back - OK only £75 or 0.5% of all the spend but it's in the right direction
"hobby operating system "
That's the 'hobby' system that's used for most supercomputers, a good proportion of servers, most scientific computing, and a good/great proportion of embedded systems & phones ?
"three years on three different laptops"
I'm genuinely sorry you've had these problems (and of course we're not going to fix them here ) but I can only repeat that my experiences have been universally positive.
Now I'm not an IT professional, although I've been around computers all my working life, and like many scientists need to program out of necessity. As well I build my personal machines and other hardware, so I'm not, perhaps, your average non-IT person either.
I'd suggest using an OpenSuse live-CD so that you can see if your hardware is working before trying to install.
"who actually compute for a living"
Agreed, before I retired I had a Linux dual Xeon workstation with seriously expensive 3D graphics hardware and so did the ~~100 other computational chemists in the company. This was all backed by a Unix fileserver and several Linux compute farms of ~1024.
Just to expand that ...
I've installed Linux on about 30 computers over the years since ~1995. Since ~2000 I've never had any problems with installation (usually Suse or OpenSuse but others as well).
Presently I have a Lenovo Celeron laptop on which I'm writing this via a USB 3G dongle, an Asus netbook which also takes the dongle, a dual-core atom fileserver with Samsung laser printer, a single core AMD 64 with a 4:3 display and a dual-core AMD 64 with a 16:9 display, and a dual core Intel at our Swiss holiday home with another 16:9 display
I don't think I could get more diverse than that lot.
Not one problem even with the dongle.
"Mouse driver can't figure out how to adjust for a non-4:3-ratio display?"
Utter FUD !!!
"still only holds 1% of the market"
That's 1% of a market where almost all computers have Windows installed from new without option and users either don't care or are told what they must use.
That as many as 1% choose to install Linux is a MAJOR triumph in my book.
"Not taking sides here - but - #"
No, if you show evidence that it works and describe how to make one AND it's a novel device you'll get a patent. After all why not esp. as if it doesn't work or turns out to be uncommercial no-one will want to license it anyway
Well actually ...
Rossi is claiming in his provisional patent that 56 g ( 1 mole) of nickel will produce energy equivalent to 30000 tonnes of crude oil so I guess the economics would be favourable.
However I think the whole thing is nonsense
"LENR Primer "
Are we supposed to take any of this cr*p as evidence ?
I've got 6 Linux installations and have installed about 5 more.
Why does it not have an enclosure ?
Back in the early 80's I assembled a UK101 single board 6502 system. That was used in the cardboard box the board came in until I could afford a case
Reminds me of a song
I've looked at clouds from both sides now,
From up and down, and still somehow
It's cloud illusions I recall.
I really don't know clouds at all.
Re: "If the universe were really formed from a single explosion"It's thought that quantum fluctuations when the universe was tiny just after the 'Big Bang' were 'frozen' by the gigantic inflationary process and give rise to the small scale heterogenicity seen On the large scale the universe is very homogenous or symmetric. It's reconciling these two observations that suggested the extremely small nature of the start point and inflation theory
If it's like the electric beetle (85kW electric motor and 28.3kWh lithium-ion battery pack.) if you could manage to drive it flat out it would last ~20mins.
"Can someone please refute this Hawking tosh without further delay??"
What you have just said has nothing whatsoever to do with Hawkings !!!!!
Re: Re re: holidays on the moon
I know what you mean. In fact our holiday home is 1800m above sea-level and nowhere near any sea.
"holidays on the moon"
The moon's overrated. OK the golf is easy but the brochures all go on about the seas and as far as I can see when you get to the beach the tide's always way out .
Ratio of phosphorous to silicon
I can't see how the doping is effective if only 4 silicon atoms are involved - I thought dopants replaced atoms in a matrix - the text and cartoon make it looks like the silicon is smothered in phosphorous
"I accidentally middle click it sends the entire bloody contents"
Settings-Preferences-Advanced-Shortcuts-MouseSetup-MiddleClickOptions & change to something else such as start panning
in that case a lot of people are working hard to produce an excellent set of distros.
"many devices out there are not advertised to work flawlessly under GNU/Linux"
I find it just as irritating to be told by a manufacturer that some device 'only' works with Windows 'X' or maybe Apple and to find that actually it works perfectly well or better with Linux.
Recent examples include a USB 3G dongle, a firewire video camera and a USB/serial converter
"name me another distro that is relevant on the desktop"
"the Linux share of the desktop market... less than other"
This might be true but EVERY one of those users have chosen to move to Linux.
In a world where essentially all desktop computers are sold with Windows or Apple OS pre-installed and where most people, in any case, don't care I'd count the desktop usage of Linux as a major success.
"ecause these systems insist that you enjoy doing the computer"
Absolute nonsense !
Well I kind of sympathise
but I have 6 machines running OpenSuse 11.4, a netbook, a laptop, 2 workstations, a fileserver and a desktop in our holiday home.
I don't have a problem with KDE although like you I'm quite happy with more 'primitve' managers
I don't have a problem with sleep mode
I have two printers - a Samsung laser and and Epson scanner/copier/inkjet which both work perfectly and network nicely from the fileserver.
I do agree about GIMP but I often process RAW photos with showFoto
I don't use Windows at all and expect to do everything I want in Linux - these days I find this quite easy.
Incidently I'm thinking of building a compute server to offload a lot of intensive scientific calculations & modeling and also for the transcoding/rendering of 1080/50p video
"They cost a bit more than £20"
@£50 from memory, would have been much more complex to produce and had loads of TTL logic on the board. I've still got one somewhere - the SC/MP machine code was a sod to write!
Re:30000 feet seems rather high
The world record seems to be ~12500m or ~40000ft.
Here in Switzerland Air Zermatt helicopters routinely haul loads of concrete etc. to ~3500m + (~11500ft)
Re:Thanks for signing up just to say that.
Amazing he just happened to be passing really !
Re : @I. Aproveofitspendingonspecificprojects → #
You are both sort of correct.
Winter solstice was indeed 22 nd Dec when the day length was shortest.
However sunset and sunrise move in phase but with a lead/lag so sunset here is getting later and has been since ~Dec 14th but sunrise is still around its latest and it'll be early January before it becomes earlier.
Want to buy a big one now ?
Re: "I am not old enough to have watched the first man set boot on the moon."
I am, and yes they had fuel cells for that.
As for the patent - this is shabby in the extreme. Many USA drug patents have had long lists of compounds which were only synthesised on paper but generally not reputable companies.
Even if I'd not seen examples of other mobile devices powered by fuel cells such as laptops ( and 12v supplies for motorhomes plus the Apollo capsule example this would be obvious in the patent sense anyway.
If Apple care to patent a specific design with some demonstrable advantage then that is patentable. But to just claim fuel cell power for mobile devices..........
