I said as much above.

In an AC system, that current is continuously changing, so those transmission lines are continuously radiating away some amount energy. But that's not all. If there are any conductors nearby, those E-M waves can induce a current in those conductors, and the resulting E-M waves from that induced current can drag on the AC line further. This mutual induction is how transformers work. But, along an AC transmission line, unwanted coupling results in transmission losses. So, an AC system has a built in, inherent source of losses in the alternating current itself.

...and...

In a DC system, with a fixed, perfectly resistive load, the current doesn't change, so there's no radiative losses. In the real world, though, the loading on the system is continually changing, so the actual current demand on the DC system will vary over time, and some energy will be radiated away. To some extent that can be filtered, but that's limited by the amount of storage you can put near the ends of the transmission.

A company that employed expensive employees in an extremely employee biased legal framework has now been destroyed and all of those employee are out of work.

The company was not in trouble because of employee laws. All this is the fallout of a "restructuring", which is just the bullshit bingo word for mass layoffs, which in turn were the result of the company being in trouble.

If your attempt to save your troubled company didn't work because you didn't take into account the effects of your actions, then that is 100% your fault. It's not like these are secret laws only told to you after the fact.

employment will work like any other unregulated economy

There is no such thing as an unregulated economy. That's just the bullshit bingo word for "company-friendly regulations".

Yes, it is good. Unless you are among the 11% unemployed, or one of the many millions with short term contracts because no one wants to take the risk of offering you a real job.

I call bullshit.

So you think the american system is better, where due to lack of such laws, basically everyone has a short-term contract because if you can fire everyone with little consequences on short notice, that is what you have.

Look, I am one of those "hard working Germans across the Rhine". Our government spent the past 20 years or so slowly dismantling the social systems and employee protections that our fathers and grandfathers had spent and risked their lives establishing (I'm not joking, one of my grandfathers was a union secretary, killed by the Nazis for his efforts).

The result is that maybe on paper unemployment is lower, but several million people spend their days in low-pay (I can't even say "minimum wage", because we freaking don't even have that!), temporary jobs. Literally temporary: They hold contracts saying that on day X, they will be out of a job unless their employer offers them an extension. You don't even have to fire them, how convenient.

As a result, average income has dropped, spending on culture and arts is dropping constantly, life expectancy has stopped to rise despite better medicine, and by some statistics a quarter of the population is in a constant state of insecurity because losing your job can snowball into losing your home and everything else because wages are so low you can't build up reserves.

Sorry, I'd rather live in a world where people around me are not in a constant state of fear and stress.

I'm beginning to feel disgusted by these cry-baby CEOs and investors.

Look, it's very simple: There are laws of physics. If your product cannot work with the set of laws of physics we have on this planet, then your product doesn't work, end of discussion. You can't cry over not being able to make the flying car of your dreams because gravity is so mean to you.

There are also man-made laws. If your company cannot work with the set of laws valid in your country, then your company doesn't work, period. You can't cry over not being able to make a profit because they are so mean to you.

It's really selfish, stupid and ignorant to enjoy the nice things that laws and regulations give you, like having a civilized country, safety, clean streets, heck streets at all, the ability to make contracts and enforce them (absolutely essential for every business!) and a thousand other things, and then cry that the evil laws make your business impossible. Quite the opposite, you imbecile! The laws make your business possible in the first place. Without them, you wouldn't have a business, and if you tried the first guy with a bigger club would take it away from you.

Sure, it's HBO, and sure they have some stellar in-house programming; but it's one channel.

Not exactly - because it's not just "HBO Now", but also "HBO Then".

That is to say, you aren't just getting current seasons of stuff like Game of Thrones - you are getting all the seasons they aired. Plus things that aren't even airing that were great - like Rome. Plus many more somewhat-current movies than Netflix has (although to be fair Netflix has a small number of near-current movies I actually like to watch, whereas almost none of the movies HBO listed were interesting at all to me).

That said I may just subscribe during Game of Thrones, then cancel again... it'll be interesting to see how I feel at that point.

don't be dense. You don't need 24/7 access to the internet to job hunt. There are lots of places you can go get access for free.

Right, but it's an awfully lot more convenient if you can check from home - especially if you're poor and have a lot of other time commitments (other job, school run, kids etc).

The money is already there, they just need to amend the wording because it was written in the 80s to say "landline or cable/dsl connection" rather than just "land line" as it does now.

I have an application for this where I'm using 365 to 395 nm older style to attract bugs efficiently.

Come on, give us a few details. Are you collecting the bugs for research or are you using the lights as bait for your backyard zapper? Or are you collecting bugs to feed to your pet iguanas?

That's too tantalizing a statement for you not to tell us a little more.

So, instead of trying focus on what kind of user experience we're going to have (which sounds like they think the tablet interface is what people actually want for everything) ... and focusing on making all of that good and usable

Have you seen Win10 preview, or at least read some reviews and look at the screenshots? Because it is exactly what it is about... I mean, the most obvious change that you see once you install Win10 over Win8 is that the Start menu is back. Other changes include things like Metro apps actually running in resizable windows, and the "charm bar" is gone, and all the actions are integrated into the window title bar. Etc... basically, all things Metro are desktopified.

Air is water with holes in it.
