Comment Re:No historical data (Score 1) 177

This is only impressive if they didn't use any historical data at all to create the new super computer. If they did use historical data then the answer would be correct by definition. The way to test this is to use historical data make a prediction and then wait a year then compare to the real data only then you have any valid comparison.

That's really dumb. Why would you wait a year, when you have 35 years of data? You test the model on 1980's data, and see how accurate it was by checking with 1981's data, and so on. They can do that 35 times, if they're looking a year ahead. If they're only looking a month ahead, they can do it 12 x 35 times.

Comment London Taxis? (Score 1) 216

Ultimately we will need to ban diesel vehicles from much of London and we need a mayor prepared to take these tough decisions and work with people to make these changes happen.

It's been a while since I was last in a London Black Cab, but I'm pretty sure it was a diesel. Are they suggesting getting rid of them all? Good luck with that.

At that same conference, my colleague talked to someone working in Xpoint R&D who told him, "If you need a solid-state drive right now, buy the cheapest Samsung model you can get by with, because in the next two years we're going to blow the competition completely away."

Oddly enough, I was at a conference last week where we had a keynote by HP. He was saying pretty much the same thing about memristors. He held up a roughtly credit card sized model that would apparently hold 1.5PB of data. It all sounds cool, but I'll believe it when I see it. These "just around the corner" technologies sometimes take a lot longer than expected to reach market.

Comment Re:Remember all those years of Linux on the Deskto (Score 1) 183

Of course they need large scale manageability. What the GP post said was that there are no tools that offer the facilities that AD and GP do on Windows. You can do a whole lot of stuff with scripts and other tools, but that doesn't mean it's as straightforward.

The real strength of GP is the ability to modify the way the software that runs on top of Windows works, not just the OS itself. Of course, MS offers the best support for that in things like Office, although other applications can be managed too. With the sheer variety of mechanisms for configuring applications on Linux, there can simply be no equivalent.

Offer me a working equivalent of GP, and an Exchange replacement, and I'll give it serious consideration. Until then, for me, it's just not worth the hassle.

Sounds like you're describing Iain M. Banks' post-scarcity Culture (I'm sure there are other sci-fi examples). That can't really happen until we have an abundance of energy and the ability to manipulate matter to create any material goods we may require. I don't see that happening for another millennia or so, assuming we last that long.

Comment Re:If you like an app buy it (Score 4, Informative) 337

If you like an app, pay the dollar or two for the ad free version, other wise you're stealing from the developer of the app, justify it however you like, but it is theft.

That's not always possible. There are a few apps that I use where there isn't a version without the ads. I'd happily plonk down a few quid to remove them, but the option isn't there.

Submission + - NASA's basement nuclear reactor (gizmag.com)

cylonlover writes: If Joseph Zawodny, a senior scientist at NASA’s Langley Research Center, is correct, the future of energy may lie in a nuclear reactor small enough and safe enough to be installed where the home water heater once sat. Using weak nuclear forces that turn nickel and hydrogen into a new source of atomic energy, the process offers a light, portable means of producing tremendous amounts of energy for the amount of fuel used. It could conceivably power homes, revolutionize transportation and even clean the environment.

1) "If they understood that better" is meaningless. I build systems to meet requirements and demands, not the other way around. Most businesses operate the same way.

I would agree. My point was that people compare a simple IMAP/calendaring solution with Exchnage and think that it competes on the same level. If all you need or want is that, then great, go for it. If you want more, there's nothing else out there that compares.

2) Starting with Exchange 2010, things have gotten far too complex just for the sake of complexity, and with little benefit (and definitely less benefit than the increased requirements justify). This is especially true in smaller implementations, where a small business doesn't need a minimum of four different servers (or two really beefy ones) just to do their email, tasklists, and calendaring.

I wouldn't disagree with that either, although what constitutes a beefy server is not an exact science, and with VM's, not that difficult to deal with. Keep in mind that most of Microsoft's recommendations for minimum specs on these sort of things, and Exchange in particular, far exceed the sort of numbers you'd be looking at with most small businesses. The real complication with 2010 as I see it is that the old style clustering is no longer supported, making a simple failover pair a pain in the arse. But, the hosted services can serve as a backup in that situation, and for many small business, hosted services may be all they need at all.

All together you can gain the same functionality running a multitude of packages. It's not going to have the pretty UI, but the upside is you don't have to rebuild your corrupted mail store every couple of months.

Have you ever run Exchange? Or are you just repeating the same tired bullshit that used to be bandied about 10 years ago? We've been running it for 10 years. Not once have we had to rebuild a mail store. If you're going to take a pot shot at it, at least try something a bit more up to date.

The sad thing is most people that haven't used Exchange just see it as a mail server. It's not. If they understood that better, they might understand why there are no viable alternatives.
