Comment Re:Listening to the Music... (Score 1) 178

I'm a librarian and you are very right that these are important things to consider.

However, most librarians that I know are committed to getting the information to the people who need it (in academic libraries, our faculty and students). You will find that libraries, including Harvard, are already investing in systems to make stuff available and easily searchable from a wide variety of sources: including all those in-house ad-hoc repositories you mention, open access sites like arXiv and pay-for material (where we can afford it).

What worries many librarians I know, is whether someone like Google can do it better, or whether we (with local knowledge of our academics) can add enough value to make it worthwhile to keep us. I think the jury is still out on that one, but it won't be for lack of effort on supporting our users

Comment Re:education is only useful for jobs (Score 1) 314

I'd be fascinated if you could provide some figures on this. I don't know which part of the world you're talking about, but I've worked in a number of UK universities and the opposite is true. It varies a bit from institution to institution, but student numbers have tripled or quadrupled in many places. Administrative staff numbers have not done the same - they've probably stayed the same. In my area, libraries, due to technology we actually employ less staff now than we did 30 years ago, and yet we serve a lot more students and open much longer hours. Some departments have a few more admin staff than they used to, but this was because that admin work was being done by lecturers and professors. It is better value for money to get admin staff to do that and get the academics to write grant proposals and publish research.

I can see where you're coming from. I've just tried my first conversation with Cleverbot, and while any judge would have be off their head to vote it human, it is at least entertainingly weird and I can see why some humans I know would get scored higher...

It isn't possible. See the "Mathematics and Computers" section of the Wikipedia http://en.wikipedia.org/wiki/ChessChess article.

According to that article there are approx 10^123 positions in the game-tree. Given that there are about 10^78 atoms in the visible universe, building enough memory to store all the outcomes of a chess game is tricky...

The Internet

Elderly Georgian Woman Cuts Armenian Internet 282

welcher writes "An elderly Georgian woman was scavenging for copper with a spade when she accidentally sliced through an underground cable and cut off internet services to nearly all of neighboring Armenia. The fibre-optic cable near Tiblisi, Georgia, supplies about 90% of Armenia's internet so the woman's unwitting sabotage had catastrophic consequences. Web users in the nation of 3.2 million people were left twiddling their thumbs for up to five hours. Large parts of Georgia and some areas of Azerbaijan were also affected. Dubbed 'the spade-hacker' by local media, the woman is being investigated on suspicion of damaging property. She faces up to three years in prison if charged and convicted."

Comment Re:Conflicting Laws? (Score 1) 352

The only law I can see conflicting with the Freedom of Information Act, is the Data Protection Act. Data Protection deals with what you can do (or not) with information about individuals. Data Protection in general will override Freedom of Information (you can't make a FoI request to find out the home addresses of the institution's employees, for example.) However, in this case tree ring data is not about individuals, so Data Protection doesn't apply.

The only reason for not complying with a FoI request in this case is that it would be too costly to comply. It appears that the Commissioner disagreed with the University about this, so they must release the data.

Comment Re:Unrealistic? (Score 2, Informative) 247

As the replies to your post show (and I can confirm through my own experience), most people I know who are on Virgin cable DO get very close to the advertised speeds. It is ADSL providers who have problems. That is not to say there aren't problems:
  • They cap heavily at peak times if you start downloading/uploading lots of stuff
  • The fibre comes no where near the home. Virgin don't appear to be making any effort to fix this, even with some old decaying coax in certain parts installed by one of the providers they took over
  • They don't appear to be extending their network at all - and I'm not just referring to rural areas. There can be parts of major urban areas that weren't cabled by the original companies that Virgin acquired, and nothing has been done since

New Most Precise Clock Based On Aluminum Ion 193

eldavojohn writes "The National Institute for Standards and Technology has unveiled a new clock that will 'neither gain nor lose one second in about 3.7 billion years,' making it an atomic clock twice as precise as the previous pacesetter, which was based on mercury atoms. Experts call it a 'milestone for atomic clocks.' The press release describes the workings: 'The logic clock is based on a single aluminum ion (electrically charged atom) trapped by electric fields and vibrating at ultraviolet light frequencies, which are 100,000 times higher than microwave frequencies used in NIST-F1 and other similar time standards around the world.' This makes the aluminum ion clock a contender to replace the standard cesium fountain clock (within 1 second in about 100 million years) as NIST's standard. For those of you asking 'So what?' the article describes the important applications such a device holds: 'The extreme precision offered by optical clocks is already providing record measurements of possible changes in the fundamental "constants" of nature, a line of inquiry that has important implications for cosmology and tests of the laws of physics, such as Einstein's theories of special and general relativity. Next-generation clocks might lead to new types of gravity sensors for exploring underground natural resources and fundamental studies of the Earth. Other possible applications may include ultra-precise autonomous navigation, such as landing planes by GPS.'"

Comment Re:An alternative they never consider... (Score 2, Interesting) 175

How do you know they never consider it? I've not heard anything specific from NASA, but they do seem to have plenty of people who do dream up long terms plans and ideas. Don't forget that most of the people there read/watched science fiction just like we did and many of them were inspired to take up their careers at NASA because of it (see various bios on the NASA sire if you don't believe me).

The problem comes in turning those blue-sky ideas into reality. There is no 'just' when it comes to space. Whenever you find yourself asking, "Why can't they just..." it is almost always for a good reason. A mothership's a great idea, but how do you build one. You've got to get the parts into space. Are you going to test the nuclear propulsion? How long will this project last and will Congress give you the funds? These are the sort of real questions that need to be answered and have scuppered programmes before now (and look likely to scupper NASA's current plans - which are less ambitious than the mothership idea).

The way I look at things, I ask are they likely to cost a lot more than what is happening now. To do this, you need to assume there will be no miracle leap in technology in the short-medium term. For example, if raising parts to space cheaply relies on a space elevator, then rule out the short-medium term. Obviously, we have ideas that one could be built, but technological breakthroughs need to happen to make it a reality. While this is possible (and even likely, I hope), don't assume that we will have a functioning elevator within 20 years.

So, using only slight advances in current tech, could we build a mothership for approximately the same as what the ISS cost? I don't believe so - it would clearly need to be bigger and would involve research and testing in propulsion systems. Given that the US, Russia, ESA, Canada and Japan are struggling to find the cash to keep the ISS up beyond 2015 (when most of it is already built) who is going to fund and build the mothership?

Sorry to sound so negative, but I get fed up with all the unrealistic ideas and whining about NASA on Slashdot. Being a Brit with a government that does no funding of a manned space programme at all, I think they do a fantastic job given the resources they have to work with.
