Comment Here's the project poster (Score 5, Informative) 315

Here's the project conference poster. "Total equipment cost for the development path is less than $1 billion". Nothing on the poster, though, indicates why this should work. It's yet another torus-based design, of which there have been many. The best performance to date is from the Joint European Torus: "In 1997, JET produced a peak of 16.1MW of fusion power (65% of input power), with fusion power of over 10MW sustained for over 0.5 sec."

All torus designs run into plasma instability problems. So far, nobody has a working solution. Nobody even has a good theoretical solution. No combination of fixed magnets has yet worked. There's some modest interest in active feedback for stabilization, and some modest success has been reported. The instabilities are on the order of milliseconds, so active feedback is quite feasible.

Even ITER probably won't work. The thinking behind ITER was originally "maybe it will become more stable if we make it bigger." Now, a little "maybe the feedback control people can make it work" has been added. It's not looking good, which is why there really isn't that much enthusiasm for ITER.

Why not using that DNS server has fixed the heartbeat ping issue.

Their router may be trying to distinguish, as Windows and most things that connect through WiFi now have to, between real Internet connectivity and fake Internet connectivity. Fake Internet connectivity is when some WiFi access point hijacks all DNS requests to take you to some login web page or ad. So, many devices try to connect to some known site which produces a known response to verify that they can connect to the outside world.

It's the choice of "known site", and not having alternatives for it, that's the problem.

Comment Less static hardware. (Score 4, Informative) 993

UNIX, and Linux, were designed with the concept that the hardware configuration was static during operation. So "startup" and "configuration" occured at the same time. Now that many peripherals hot-plug, that model is obsolete. Many people find it painful to switch to an "everything is dynamic" model, especially since, for many server applications, there is no hot-plugging.

Hence the unhappiness with a redesign.

This is a more general problem with UNIX/Linux. Many programs are designed on the assumption that they read a static configuration file in text format, and will be restarted if the configuration changes. Various hacks have been added to some programs to allow dynamic reconfiguration (often involving sending a signal to the process to tell it to re-read a text file). Real dynamic configuration models usually involve storing the configuration in a database, which a lot of UNIX/Linux types don't like.

Comment Happy talk financials. (Score 0) 171

last quarterly financial numbers. Note the -62% margins. Uh oh. The press release has lots of happy talk, but the numbers don't back it. ("GAAP" here means Generally Accepted Accounting Principles. Those are conservative assumptions. "Non-GAAP" numbers are numbers adjusted based on management's exclusion of certain negative items. They're usually flaky.)

The company was profitable at the beginning of 2013. They should have turned down the Apple deal. It's not good to have one big customer.

Comment "Feedback" code in the release version? (Score 1) 367

This is a huge vulnerability. Microsoft's claim that the code "turns off" after the test period has to be viewed with scepticism. If they can turn it off, they can turn it back on. Or someone else can.

This is telling us that Windows 10 is totally unsuitable for any business with security requirements. Lawyers, banks, and medical service providers probably can't use it and be compliant with the regulations in their industry.

Comment Android without Google. (Score 3, Interesting) 107

When do they set up a "Cyanogen store"?

Even without Cyanogenmod, Android phones work just fine without Google services. At first power-up, there's a "sign up/log in" screen, with a "Later" option. Click "Later" and go on.

You can disable the "Google One-Time Startup" app to keep it from bothering you again.

Comment How fast did they report this? (Score 1) 209

If this was reported immediately, the sewerage plant could increase their chlorine injection to far higher levels than usual. Chlorine will destroy polio virus. Sewerage plants usually chlorinate at a modest level to kill bacteria, but in an emergency like this, they can easily crank the levels way up. Sewerage plants are constantly adjusting their systems depending on what's coming in.

If the safety people at GlaxoSmithKlein, or whoever this was reported to, called the plant operator at the sewer plant, there would have been immediate agreement to crank up chlorination levels, and sampling would have been started at the sewerage plant. The reports, which indicate after the fact analysis, indicate that didn't happen.
