You need to use liquid crystal glasses NOT beer goggles
can produce that effect. I've spent a lot of time looking at 3D chemical graphics of various types over the last 30 years and have got used to the games they can play. If you cross your eyes or defocus them you might well find the images shift around to give the impression that you are looking from below. Try changing the size or darkening the room.
Thanks for that, pity it was so small.
Having done this quiz I guess one problem is that it isn't against the clock so I had plenty of time to scrutinize the pages and particularly the URLs. In some ways it was easy to spot the phishing sites but verifying that a genuine site was genuine was harder - spot the phish and you're done but on the 'good' sites it took more searching to convince me that there wasn't some trick.
But how many people did your survey cover ?
Not on my system mate
Just like the desktop ?
Just card in/out - no PIN
Spent ~£380 recently going Calais-Switzerland-Riviera-Auvergne-Calais with the largest single item ~£40 all without PIN or signature - I guess they have the reg. plate captured though.
Both electricity/gas I put the readings in on-line, bill gets paid by DD, meterman turns up about a week later. Being going on for ~ 2/3 years
It didn't read like a joke
sudo version 1.7.6p2
"daringly innovative; on the cutting edge. "
Your point is ?
And I have been on this site for a number of years. And there does seem to be a tendency for posters to get their facts wrong - often wildly so.
Recently someone claimed that the NEO was 6 miles in diameter where most info sources were saying ~11m or bus sized
er ? 11 metres is closer
"The asteroid, estimated to be about 11m (36ft) in diameter, was first detected on Wednesday."
"A small asteroid the size of a city bus zoomed between Earth and the moon's orbit Friday (Jan. 25)"
I agree about the nuck though
Quite the reverse.
A charged comb will lift a feather ( against the force of gravity) but the uncharged comb doesn't
I think the problem is that the rock is most to be both an irregular shape and likely to be tumbling so to attach any form of propulsion to it and then stabilize and steer it is going to be mighty hard
It does sound fanciful doesn't it ?. Nevertheless that is exactly what is being proposed in the document referenced in the article under the title "Gravity Tractor"
"..minimize fuel consumption and maximize the asteroid’s deflection? What are the trade-offs between the mass of the tractor, the distance between the tractor and the NEO, the control laws, and the time required to produce the required deflection? Reliability is a crucial issue given the long periods (several years to a decade) typically required for gravity traction to produce the required deflection. What are the requirements for autonomous spacecraft control procedures to manage hovering station keeping and maintain stability of the traction system over a long period of time in the (verynearby) presence of an irregular rotating mass?"
That is indeed what is being proposed although the object would have active propulsion to slowly 'tow' the NEO away from a collision course.
There are enough misguided souls on this site who seem to believe almost anything they are told. It's one thing to be a lively, edgy tech. site - quite another to be an off-shoot of the Daily Mail
Will you STOP using this wildly inaccurate description of the actual proposal !
e.g. the Linux kernel Oh wait !
And yet we still use it - I wonder why
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
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.
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.
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
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."
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 ?
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 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.
Ditto but with OpenSuse on it
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.
I used the "Windows inside" sticker to adorn the lid of a waste bin
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
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.
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
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
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 ?
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.
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.
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.
Utter FUD !!!
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.
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
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
I've got 6 Linux installations and have installed about 5 more.
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
