Scientists Twist Radio Beams To Send Data At 32 Gigabits Per Second

Electricity Likes Me This won't amount to anything... (68 comments)

It's been shown that all these "helical" polarization schemes are degenerate forms of MIMO essentially, and can't achieve speeds better then what MIMO antenna configurations can.

At short distances in quiet environments, you can do a heck of a lot which will never, ever work anywhere but in that experiment.

Obama Presses Leaders To Speed Ebola Response

Electricity Likes Me Re:Grim (196 comments)

There is some level of quarantine - the liberian government blockaded in the slum area where a clinic was raided, and sealed off about 50,000 people. That's probably about the limit of their efforts.

But frankly, you're also ignoring what's been actually happening: such an ambassador catching Ebola in one country, knowingly returning to another (via air travel), then staying in a hotel without telling anyone being treated in secret by a doctor, who also doesn't tell anyone, goes home, and spreads it to his wife.

Queue a couple 1000 potentially infected, by a vector which would be utterly missed due to plain old corruption and idiocy.

So what do you do now? Expand the quarantine? Do you even have enough troops to do that? And in the meantime, what about all the regular issues such as food and water, sanitation and normal completely curable diseases which will take hold.

Torvalds: No Opinion On Systemd

Electricity Likes Me Re:Sounds like Mr. Torvalds has an opinion. (327 comments)

I think he just doesn't care about things that don't get in his way.

A few weeks ago, when systemd would lock up the system if you turned kernel debugging on, he did have rather colorful opinions about systemd and the systemd developers who insisted that systemd was doing the correct thing.

That's also just Linus reacting to stuff he thinks he's right about. And well, he frequently is. I don't really approve of the way he structures his rants sometimes, but the dude gets things done.

Torvalds: No Opinion On Systemd

Electricity Likes Me Re:Simple set of pipelined utilties! (327 comments)

It can be a collection of utilities all dependent on each other, running 3 or 5 or 15 services all communicating with each other, all to bring up the system and supply system state management. This is the simplest and easiest way to make a complex system

Why not make 3-15 modularly written sets of source files, and compile them into a single binary ? It's hardly more complex than 3-15 separate programs, and it makes communication of structured information a lot easier.

And is in fact, how SystemD is put together and intended to be expanded, for better or worse.

WD Announces 8TB, 10TB Helium Hard Drives

Electricity Likes Me Re:When can we stop selling party balloons (296 comments)

It's not being priced according to the long-term cost or capability of supplying the volumes that are being drawn from the stockpile on a sustainable basis, which is what you'd actually do if you were running a business dealing in actual production.

Yes, clearly all the people investing THEIR OWN MONEY are complete idiots, and you, a random guy on the internet, are so much smarter than actual investors and professional geologists. So does this mean you are going to invest all your money in helium futures, that are obviously going to be worth billions when the helium runs out, just like all the arm chair doomsayers are predicting?

Will you take the futures option the other way? That the current prices are going to stay at the level they are for say, the next ~20 years plus or minus 10%?

I don't know who you think is investing in this. People are just buying helium because they need it. The smart people are investing in gas mining because that's always profitable, and the big companies building huge helium liquefaction facilities are absolutely betting the price is going to rise in the near future.

Apparently the free market thinks you're kind of an idiot about this.

Information Theory Places New Limits On Origin of Life

WD Announces 8TB, 10TB Helium Hard Drives

Electricity Likes Me Re:When can we stop selling party balloons (296 comments)

Yes I guess that is why a gas we can only mine tiny quantities of from natural gas reserves is currently being sold off for party balloon use.

Helium is being sold off at any bid price on the assumption that the stockpile is unlimited and needs to be liquidated. It's not being priced according to the long-term cost or capability of supplying the volumes that are being drawn from the stockpile on a sustainable basis, which is what you'd actually do if you were running a business dealing in actual production.

Apple Announces Smartwatch, Bigger iPhones, Mobile Payments

Electricity Likes Me Re:Lame (730 comments)

A great watch is expensive and made in Switzerland. That's how watches work. Nothing about them makes any sense because the product is fundamentally not about time telling technology, except in an abstract "it's pretty awesome this is just gears and springs" sort of way.

This is not a good smartwatch at $350. It's a bad sportswatch - because it doesn't standalone from the iPhone, doesn't have GPS, and yet is in the same price bracket.

My personal opinion is that on deeper analysis the whole smartwatch thing is a deadend which is being pushed because it's looks achievable, rather then innovative. But there's some fairly obvious problems with what Apple has on display - and they're the same ones as every other smartwatch.

3 Recent Flights Make Unscheduled Landings, After Disputes Over Knee Room

Electricity Likes Me This thread basically proves the point... (813 comments)

Seriously, the number of people talking about how this isn't a problem, while simultaneously - gleefully - discussing what they'll do if someone tries to take their room, or someone won't let them take their room, pretty much dismisses any counter-argument to the idea that there isn't a problem.

There obviously is.

3 Recent Flights Make Unscheduled Landings, After Disputes Over Knee Room

Electricity Likes Me Re:Lets use Anthropo-sedatives instead .. (813 comments)

If the plane has an emergency in any place that's not "on the ground and stationary" your chances of being a survivor are pretty much zero anyway.

But if we went with the Fifth Element approach, you could design planes which could eject their passengers in parachuting buoyant pods or something.

You Got Your Windows In My Linux

Electricity Likes Me Re:Troll much? (613 comments)

Who cares? Do you really think it needs to be ported to Windows?

Do you really not acknowledge the existance of FreeBSD, NetBSD, OpenBSD, AIX, Solaris, HP-UX, and more?

OpenBSDs entire development philosophy is to develop only for BSD, and let porting take place as patchsets on top of it.

That's why LibreSSL has has support for Windows stripped out, despite it being an important SSL platform.

Hidden Obstacles For Delivery Drones

Electricity Likes Me Re:It's a proxy for needing to revamp the post sys (215 comments)

And you have missed all the subtlety of the problem. For one thing, there's no way anyone's fitting an iPad package into a mailbox, or even through a mailslot.

There's no way to distribute or update keys rapidly enough to make them general use for delivery companies and the post.

Which is the entire point: the century of mail was for mail with packages considered the exception. Special case enough to warrant needing to be physically present to receive them, or simply gambling nobody steals them when left on the front porch.

Basically you might want to take your last line there and apply it to yourself.

Hidden Obstacles For Delivery Drones

Electricity Likes Me It's a proxy for needing to revamp the post system (215 comments)

The drone delivery thing seems like a proxy for the fact that the regular postal system desperately needs a revamp to include more standardization. Basically, we need some system which acknowledges that parcel and package delivery is an increasingly important part of the process, and we want to receive things unattended.

You can only sometimes get this now.

If we had a system where we standardized mailbox sizes to some specification, and then licensed out some NFC/smart card system to let postal workers/delivery companies open them, then we might be getting somewhere. Sure, it's not perfect and it wouldn't be everywhere at once, but if you could simply buy the relevant thing at Home Depot and then delivery companies could be expected to use it, it'd be progress. Then the free-market innovates from there: various multi-tiered security products or the like.

Hidden Obstacles For Delivery Drones

Electricity Likes Me Re:Property rights (215 comments)

The various flight ceilings on commercial aviation might speak to that, but I seriously doubt any court is going to interpret the law as being about property rights as opposed to public safety / nuisance.

You have all sorts of protections from things that never touch your property, but they're definitely not defined by the property boundaries. For instance you can't demand that soundwaves do not enter your premises at all - instead you can possibly get a neighbours air conditioner moved so it isn't above a certain volume, within the bounds of what's considered reasonable.

Scientists Found the Origin of the Ebola Outbreak

Electricity Likes Me Re:Dangerous virus (86 comments)

So I guess we shouldn't worry about Ebola either coz you don't think you'll ever get it either? Check your hipster-holier-then-thou-attitude at the door mate.

Influenza infects hundreds of millions of people every year, but kills only a tiny fraction of them. To die of influenza you need to have complicating conditions. The type you had are curable with drugs we already have. The type which aren't are the type of lifestyle or age related issues which are a problem no matter who gets them, and regardless of whether you get the flu.

A virus for which we also have a vaccine.

By every measure, influenza is not scary. People who get it do not expect to die of it. But we're also going to be able to bugger-all to stop it being a yearly global epidemic. Which is fortunate, because again, it's very hard to die of it.

Should police have cameras recording their work at all times?

Electricity Likes Me Re:...like dash cams. (455 comments)

Start by letting them turn off the cameras with discretion. If they wind up not recording during notable incidents, that's going to play badly against them in court.

There's no reason to let best the enemy of better here.

Scientists Found the Origin of the Ebola Outbreak

Electricity Likes Me Re:Dangerous virus (86 comments)

despite the fact flu is a much more common (and less "scary") disease.

Flu is killing 200.000 to 500.000 people globally every year.

Dying the flu generally requires complicating conditions. Most people survive it just fine. Ebola is scary because most people don't survive it.

Islamic State "Laptop of Doom" Hints At Plots Including Bubonic Plague

Electricity Likes Me Re: But is it reaslistic? (369 comments)

So has the genetic code of numerous pathogens. That doesn't make them easily created. For a simple example, we currently have an entire field dedicated to bottom-up synthetic life creation (start with a DNA sequence, and bootstrap a cell). That's a hot field, which has required thousands of man-hours to understand.

Terrorists in field laboratories without proper equipment are not going to be accomplishing it. It is a huge expensive project.
