Microsoft Partners With Docker

multi io Re:what the hell could this possibly mean (104 comments)

Docker containers are like VM's but smaller. I think what it means is that a Windows server / VM will be able to run dozens-hundreds of Windows micro-services inside a Docker for Windows infrastructure. Or basically once finished you as a developer can now write Windows apps that don't need to install and will run on any Windows, no more version dependencies! Just like Docker is doing for Linux today.

Yeah, but wouldn't it have to be rewritten from scratch on Windows? AFAIK there is no chroot, cgroups or anything like that in Windows (I guess there might be equivalents). And I have no idea what you would do about the registry blob in this scenario.

Independent Researchers Test Rossi's Alleged Cold Fusion Device For 32 Days

multi io Re:He tried patenting it... (986 comments)

it emits the 1.5MWh over a period of 32 days, not one hour

FYI 1.5MWh running for 32 days is 1152MW.

No, it's a little shy of 2 kW.

Independent Researchers Test Rossi's Alleged Cold Fusion Device For 32 Days

multi io Re:He tried patenting it... (986 comments)

If all it is, is a battery, then by itself it would be worth almost as much as cold fusion, as it can store and produce 600+ horsepower for an hour (1.5MW hours).

It doesn't store it, it has a power supply (even officially). And it emits the 1.5MWh over a period of 32 days, not one hour. And oh yeah, it never seems to work unless Rossi is present to "supervise" the thing.

What Will It Take To Run a 2-Hour Marathon?

multi io Re:Isn't "Cutting the Wind" cheating? (254 comments)

Isn't "Cutting the Wind" cheating?

Isn't anything is cheating or not cheating relative to a constant set of rules that are applied consistently? The current set of rules happens to allow wind-cutting and refreshment points along the track, but not 1000m downhill slopes or using a motorcycle.

What Will It Take To Run a 2-Hour Marathon?

multi io Re:Two hours (254 comments)

Doesn't seem any less "meaningful" than any other sports activities, e.g. baseball, car racing, or the Superbowl. Myself, I find it pretty damn impressive that anybody could run 42 kilometers at a speed that I couldn't sustain over 500 meters.

Fusion Reactor Concept Could Be Cheaper Than Coal

multi io Re:Wait... (315 comments)

That would be Cold Fusion. The type of fusion where the energy goes most nearly into electricity.

That's aneutronic fusion, not cold fusion (it tends to be even hotter than neutronic fusion).

Elon Musk: We Must Put a Million People On Mars To Safeguard Humanity

multi io Re:uhh (549 comments)

I think Musk just jumped the shark.

How so? He's been saying this for years now, in one form or another. And as a society you're lucky to have some crazy people like Musk to make up for legions of bean-counter types.

Elon Musk: We Must Put a Million People On Mars To Safeguard Humanity

multi io Re:Scratches Head (549 comments)

I suppose the number of trips to deliver a million humans to the Red Planet could be reduced if they could be convinced to breed once they arrive there.

That would defeat the "genetically diverse" requirement.

Where Whistleblowers End Up Working

multi io Re: Good vs Evil (224 comments)

Maybe they should apply for a job at an organization that's under "intense scrutiny" by the government anyway. The ACLU maybe?

Next Android To Enable Local Encryption By Default Too, Says Google

multi io show stopper (126 comments)

The device encryption feature is apparently designed to always use the lock screen password. So you're forced to have such a password, which you have to enter every time the device comes out of sleep mode, AND (much worse) it breaks essential apps like SkipLock that want to disable the lock screen under certain conditions, e.g. when you're within range of a known WiFi network, thereby relieving you of the need to enter your PIN about 5,000 times a day while you're sitting on your couch at home.

Unfortunately, this is a total show stopper for full device encryption.

European Space Agency Picks Site For First Comet Landing In November

multi io Re:Sounds challenging. (35 comments)

The probe is in orbit around the comet, and a quite peculiar orbit too. So regardless of what the comet does, from the reference point of the probe, it is "rotating".

I don't think so. The comet may not be rotating on its own. Which would mean that all patches of its surface rest in an inertial frame (at least if you ignore the rotation around the sun -- which shouldn't have much influence during the short timespan of a landing). If that were the case, it would make the landing easier because the lander's velocity relative to the surface would stay constant during unpowered flight phases.

RAYA: Real-time Audio Engine Simulation In Quake

multi io Re:What if you tilt your head in headphones? (89 comments)

I never understood those head trackers. I mean, if I have a screen in front of me and turn my head to the right, then the display may very well change but I'm now looking to the right so won't see it (or need to look out of the corner of my eye). If instead I have a bank of monitors, so that I could see any adapted view - it wouldn't need to change the display!

Email Is Not Going Anywhere

multi io Re:serious confusion by the author (235 comments)

Email is actually a tremendous, decentralized, open platform

Right, because people understand and care about that.

You could say people didn't understand or care about the web being a decentralized, open platform either. But that was still the reason why it took off, and ultimately the (indirect) reason why everybody started using it.

Email Is Not Going Anywhere

multi io protocols vs. web sites (235 comments)

The main difference is that email is a (suite of) protocol(s), while all those other things are essentially web sites (with a mobile app, and a REST API if you're lucky). Which means that with email, you can deploy a complete implementation yourself, in your own organization or wherever you want, without having to rely on specific 3rd party services or software. This may ultimately make email last longer, because it is truly decentralized. It also means that email can scale up and down effortlessly. You won't send your cron job errors to Facebook or Twitter (or Asana).

Report: Nuclear Plants Should Focus On Risks Posed By External Events

multi io Re:already done (133 comments)

Now, Post-Fukushima, plants are adding response capabilities for apocalyptic type scenarios even though three is nobody that can provide an example of how such an event may happen for the particular site short of some major war type event. Fukushima was simple...don't put reactors that were not design to operate underwater where they can find themselves underwater. Given the situation, the outcome was quite easily predictable.

Can you cite any pre-Fukushima regulation that mandates this? Because if you can't, then that's a case of "hindsight is 20/20". I'm pretty sure the type of thing that happened at Fukushima has always been thought to be a "there is nobody that can provide an example of how such an event may happen for the particular site" type of scenario -- until it did happen.

Damian Conway On Perl 6 and the Philosophy of Programming

multi io Re:Fourteen years? (132 comments)

Come on! In fourteen years you can develop your OS from scratch. Bearing in mind that Perl is noting more than a scripting language, what the hell have they been doing?

If I had to make a totally uninformed guess, I'd say they probably read and learnt so much about languages, interpreters and compilers and stuff that they're now totally insecure as to how to proceed.

Germany's Glut of Electricity Causing Prices To Plummet

multi io Re:Another misconception bites the dust (365 comments)

I don't think anybody can give you am exact date on when coal power will be phased out

Yeah, because nobody knows how you could run the grid without them. You certainly can't run it just on solar+wind+some measly storage capacities on the same scale as today's. If Germany were to run on solar+wind plants alone all the time, they'd need the ability to store one or two weeks of electricity consumption, which amounts to 10..20 TWh -- that's at least 200 (two hundred) times as much capacity as is installed nationwide today. Which means you'd need totally different storage technologies, some of which you may have to invent first. Nobody is sure how (and whether) this might work.

but the energy transition effort enjoys fairly broad support among the German public

Which doesn't change the physics. And, what actually "enjoys broad support" is getting rid of all the nuke plants. So the only date that was fixed early on in this whole effort is the day when the last nuke plant would be shut off. Because not doing that would've cost Merkel her reelection. Everything else isn't nearly as important.

If she can't tell you she doesn't want it unplugged then it isn't.

She is fully conscious, so she can tell him. "Telling" doesn't require verbal communication ability.

Ask Slashdot: Communication With Locked-in Syndrome Patient?

multi io Brain-Computer Interfaces (552 comments)

It's not a direct help, but I can tell you that it's certainly possible these days to communicate and control external actuators using brain activity only. What they're doing (AFAIK) is record the 2D electrical activity on the brain's surface (using EEGs on the scalp or -- for even greater accuracy -- below the skull bone), analyze it statistically and deduce what the person is thinking of doing, e.g. move a mouse pointer in some direction and choose which of several buttons to press. It requires a learning phase, but then the accuracy is quite high. I'm not sure about the actual bandwidth that you can achieve when communicating using this method only, but it's much better than what was possible only a few years ago, and it's improving further.
