Comment Re:Ha, not the first (Score 3, Interesting) 185

building a supercomputer means getting thousands of CPUs to cooperate which is a much harder challenge.

Looking at his presentation, that seems to be his point. He concludes that power efficiency is going to become the limiting factor driving design decisions, and that since the power cost of increasing FLOPS has been so much lower than the power cost of moving larger quantities of data we're heading into an era where connectivity costs will so dominate the cost of cycles that cycles will be essentially free.

Hes's then basically arguing that it won't be cost-effective to build data transmission architectures that can effectively utilize exaflops, so no one will bother to build an exaflop machine.

He didn't state it, but if the rest of his arguments are correct, perhaps we're going to see the definition of a new metric for HPC, one that somehow captures the ability of a machine to distribute data to its computation nodes.

These are makeshift solutions. With an ever growing population all solution we come up with, besides of reducing population and consumption, is rather temporary.

We don't have an ever-growing population. Worldwide, we're already basically at replacement level reproduction, and the industrialized world is at less than replacement level when you remove immigration. Europe's population is declining, period. In Hans Rosling's terms, we have reached and passed "peak child"; there are just shy of 2B children in the world and that number is not increasing and -- based on current trends -- not going to increase.

Assuming we maintain a constant level of 2B children, that means that there will be 2B people in each living generation, putting us at a steady-state population of about 10B. Actually, barring significant changes in current trends, that won't be a steady state, it will be a high water mark. As wealth and -- more importantly -- female education levels continue to rise around the world, the birthrate in what we now call the developing world will also drop below replacement and the population will gradually decline.

Rosling explains it well: http://www.ted.com/talks/hans_rosling_religions_and_babies.html

Maybe someday they will actually get a marketing department that understands that the latest thing from "Fart Around Fridays" shouldn't always be "released" unless they have good reason to believe that it's sustainably profitable by some metric and they are willing to sustain it even if they are wrong in their projections. Should they choose to do so someday, it will be hard for them to become "adults" given their reputation over many years.

Actually, I think that's what has happened, and it's what's caused Google to acquire the bad reputation you speak of. When Larry Page took over a couple of years back, he immediately started demanding more focus on "world-changing" projects (at Google success is measured more by impact than by dollars; the assumption is that if you have a big enough impact there will be a way to make it profitable), and cutting the long tail of projects that weren't getting enough usage.

In your terms, Google is becoming an "adult" company, which is why they've been gradually canceling all of the non-hits which were introduced during the "throw anything and see what sticks" era -- like SMS search, assuming it's actually been cancelled. Google still does (and I hope will continue to do) more ambitious, speculative stuff than any other company out there, but there is definitely much more focus on demonstrating first that a project is going to be successful (i.e. hundreds of millions of users) than there used to be.

(Disclaimer: I work for Google, but these are my own opinions, not official company positions.)

This always happens. Lowest cost + government insurance = safety failure.

It's a government project, entirely overseen and operated by the Department of Energy. There's no private corporation to blame here, sorry. Insurance isn't even relevant since the government itself would hold the liability -- if it weren't exempt from civil liability anyway.

Comment Re:The trouble with using Google accounts (Score 1) 91

Print it out and put it in your wallet? No, no.. bad idea.

No, that's a good idea, and exactly what you should do. Yes, it means that an attacker who manages to get your password and your wallet can get into your account, but that's still far more secure than a password alone. If your alternative is not using a second factor because you're afraid you won't have it when you need it, you're far better off using two factor and keeping the list of backup code list in your wallet.

Google offers SMS messaging as one of the methods for second-factor auth.

"you'll be asked for a code that will be sent to you via text, voice call, or our mobile app." (http://support.google.com/accounts/bin/answer.py?hl=en&answer=180744)

There are actually a couple of other options as well, including a code via e-mail and a hardcopy list of pre-assigned one-time-use code, though they're mostly intended for recovery, in case you lose access to your phone. And you can also provide a backup phone number.

They still have eleven more chances at the circuit court level, if you include the DC and federal circuit courts.

This is the federal 9th circuit court of appeals, so its decisions are binding on all district courts in the 9th circuit. Yes, there are 11 more appellate courts (10 circuits, plus DC), on whose courts this decision is not binding... but it still establishes a persuasive precedent that other circuits are going to be reluctant to ignore. If they got another appellate court to disagree with the 9th, it would go to the Supreme Court for a decision. If, on the other hand, they the other court sided with the 9th, the non-binding precedent would become almost impossible to override.

So, no, they don't have eleven more chances, nor even 10. At best they have one remaining chance, and it's a very, very long shot: go to trial in a district court in a different circuit, win that, win the appeal and then win in DC. Given that AFAIK they haven't found a single judge who didn't slap them down, I think that's vanishingly unlikely.

Comment Re:Imagine the day you're booted off Google (Score 1, Informative) 250

What a load of FUD.

Google is a wonderful company, and their products are useful and seductive and beautifully interlinked. But they're free to use and you're not the customer. And every day a certain number of people have their Google account blocked, for one reason or another, and find that there's no recourse to Google to fix that. In fact, there's no customer service department at all.

Examples on the internet of this are easy to find: http://www.searchenginejournal.com/open-letter-to-google-why-have-you-taken-away-my-google-gmail-accounts/7873/ http://classicsynth.hubpages.com/hub/How-to-Get-Disabled-Google-Account-Back

If they're so easy to find, why did you post only one, from 2008, who was locked out for only 15 hours? Your second just said that Google might temporarily disable your account if they suspect it's being attacked (hint: you probably want them to disable it in that case) and that Google will offer you some account recovery options.

Now imagine that this happens to you, and your laptop has just become a paperweight. And this time, you've paid for it. Hmmm.

Not true. You can still log on to your Chromebook and use it as a web browser, including whatever you need to straighten out your account problem. You just won't be able to access your Google account stuff. If you haven't set it to disallow other users, in the worst case (somehow you simply cannot recover your Google account), you can always use it to create a new Google account. If you have set it to disallow other users, you can always reset it to factory configuration and log in with a new account.

In short: In the unlikely event you truly lose access to your Google account you will have lost access to everything in your account... but your Chromebook is still yours, is not locked to that account, and can be used just as before with a new account.

Also, since you buy a Chromebook, there are customer support centers to help you: http://support.google.com/chromeos/bin/answer.py?hl=en&answer=1280301. I'm pretty sure Google provides customer support for all of its paid services.
