90% is not possible without violating some basic rules of thermodynamics or physics.. You are an idiot.
Pumping up water: has nothing to do with thermodynamics. There is no physical reason that it could not be 100% effective. As I pointed out: it is already above 90%
Running water down: has nothing to do with thermodynamics, either! And hydro plants are above 90% efficiency all over the world since literally centuries!!
So: the combined efficiency in pumped storages is above 80%... (I never claimed 90%) BTW, as you came with the thermodynamics bat: the laws of physic define that the maximum efficiency is 100%. Because conversion of energy is always 100%... law of conservation of energy. In the above scenario however, not all kinetic energy is converted into torque in the turbine, some kinetic energy remains in the water (same for the reverse way in case of pumping: and that has nothing to do with thermodynamics - facepalm).
This is an environmental nightmare for multiple reasons.. Strange that this is only the case in the USA and the much smaller Europe has no such problem... Perhaps you should once visit a pumped storage plants. In my country they are considered resorts of nature and a holiday paradise. Ofc that is not true for every basin, sometimes it is just made of concrete and is to remote to be reachable for tourists.
Finally, the demand curve doesn't stop when the sun doesn't shine, but solar collection DOES Wow... why don't you simply google for a demand curve? In my country demand more or less goes straight down to base load after sunset, in summer for certain and in winter with a delay of 3 hours.
Who cares about the fact that emergency power needs Diesel? It is supposed to never be used...
Regarding your idea about Blackouts, sorry. Such isolated grids where your scenario could happen don't exist in Europe. And most civilized countries have a decent grid where such scenarios can not happen either.
If an "isolated section" gets in to "unbalance" as you call it, balancing power plants and reserve power plants come into play. At least in my country and in Europe.
The only way to have a black out is a physical cut of the "isolated section" from the grid. There was no other kind of blackout since minimum 80 years in Germany, and I doubt somewhere else in Europe (and I also doubt that for the USA).
Of course, the exception to that are scheduled power offs in case of construction work etc.
Ah, I remember around 2000, Italy had a blackout in the northern part because they preferred to import a significant part of their power via single power line. Now they are much better interconnected with the rest of Europe. The only other grids where I could imagine scenarios like yours are USA (obviously) and UK.
OSes don't have security issues that effect a single APP. And yes, all communication after the connection is established is a P2P connection.
Microsoft account (formerly Passport.net) credentials can be used on not only Skype but also on numerous other services. That is why *I* and most people I know, use a Skype account for Skype, and not... what exactly is the name of your account?
In my over 30 years of software development: 1) I never had a coding standard where gotos were banned 2) I never saw a goto in any C or C++ code... except on internet forums where it was attempted to be justified (usually very bad examples)
But again: I'm not a zealot against gotos. I'm rather a zealot against discussing gotos... sounds like a waste of time, seeing 1) and 2)
Facepalm, for one who claims to be in that business... The OS is not insecure.
WhatsApp can compile their App for any older OS version by simply selecting the right check boxes in the IDE or giving the right command line options.
It is a fucking chat client... there is nothing in new OS versions that is required to make it work or gives a good reason that it does no longer work/can be compiled for old OS versions.
Your regression testing argument makes no sense... do your regression tests suddenly not compile anymore?
There are no double blind tests about allergies. That would be idiotic. Would you do a double blind test with Arsen, or Plutonium or something else you know you are allergic to? Perhaps you want to read up how allergic tests are done...
Well, they did not 'hit the market' in Europe..i guess they are strictly speaking not forbidden. On the other hand tomatoes are a story of misery anyway, you can not buy tasting tomatoes since decades...
Hospitals have emergency back up power, even in "third world" countries... no idea where you live.
Black outs... unless there is a disaster with a huge area effected, there are no black outs.
Black outs are grid problem... is there a wire going into region A after all other wires are destroyed?... and not a question of the power source... at least in: Europe.
Stop using your idiotic grid and power problems as arguments when the rest of the civilized world has not your idiotic grid and power problems..
Solar curve matches the demand curve quite nicely in most countries. No idea if YOU have an AC peak at the afternoon in the US. Most countries have not. And turning solar panels more westward would account for such a peak.
Then to your battery recharging meme... recharging is close to 99% efficient, the loss is marginal.
No idea where you get your numbers from.
Large scale storage is usually done with pumped storage, both pump and turbine are over 90% efficient, so the total efficiency is always over 81%... usually around 85%.
Looking at your last sentences, I really wonder if you are a payed agitator here on/.... if you are, keep in mind the user base of/. is still rather low, waste effort to spread your anti renewable myths...
Because like diabetis it is a so called 'civilization' sickness. On the other hand, I guess in earlier times people died due to allergic shocks or eating grain/wheat was not as widespread as people think. No idea. I guess if you ask around amoung your friends you figure about 1% - 2% is alergic to gluten. I don't have so many friends but I already know about 10 who are alergic.
Your explanation has nothing to do with thermodynamics, but alas... Here: http://nssdc.gsfc.nasa.gov/pla... We kniw since nearly ten years, that there is water ice on the moon.
No one complained when it was used to bring disease resistant genes into tomato. You must be very young, Padawan. Or how is it that you missed those news? Are those tomatoes even still on the market? I doubt it. The rest of your post is 90% wrong. I hope you never have to make decissions in that are of 'sciense'.
In many western countries a noticeable amount of the people are alergic against gluten. Making wheat products gluten free is cumbersome. And not only wheat comtains gluten... Being required to check everything for being gluten free is time consuming, so people like to buy stuff that is guaranteed to be gluten free, like quinoa.
Sorry, the Skype and WhatsApp upgrades/forced upgrades have nothing to do with keys or credentials. And yes, worst case I would prefer to keep it "unsecure". Obviously I communicate nothing via WhatsApp or Skype that needs protection. For stuff like that I always use a secure way. And as my friends on WhatsApp or Skype are not in the child porn business all the pictures we exchange are ok and no one cares if they 'leak'.
Skype needs the server only for initiating the connection. As soon as a call is running it is a p2p connection. Again any encryption is irrelevant, or only relevant for people with special needs or fear of eavesdropping on the line directly.
The credentials used on WhatsApp and Skype are obviously unique to those services... they can't be reused.
I can not say anything regarding Signal. I frankly forgot about it, but reading now on Wikipedia it looks promising. Especially encrypted SMS/MMS... I wonder how that works.
Regarding the programs I mentioned: Telegram offers cost free unlimited storage (I don't use it intensive enough to see how good it works when offline) and strong encryption. Disadvantage: I don't know/did not check where the servers are.
Discord: strength is chat groups and like TeamSpeak voice chat in groups especially suited for games and large groups with several hundred listeners. They offer self hosted (p2p by the players/users) "servers" and free public servers.
Threema: encrypted and data hosted in Switzerland under bank protection/secrecy laws.
All the later three have no video chat, I believe Threema not even voice chat.
Hope that helped. (I use all three for different purposes)
Calling a library function probably yes, but that a programmer wrote a recursive function, can't remember that. OTOH, I'm not hunting for stuff like this. In other words: if I have not seen one, it does not mean there are none. It only means I did not run over it through code reviews or debugging etc.
People defend proper use of goto in C fiercely Then reread my post.
The defend it fiercely because they don't understand the meaning of "GOTO considered harmfull".
Again: the resonating phrase was coined in a context where roughly every 20th statement was a GOTO. It never was meant to abolish GOTOs in situations where it is the straight forward solution.
because of the constant stream of idiots who've never worked with that sort of code, but are sure it must be wrong I don't think such idiots exist. I never met one and I definitely did not meet one in this discussion on/.
Or to close the circle: I would not distinguish between "those idiots" and the "idiots who immediately jump on the bandwagon of pointing out rare situations where a GOTO is appropriated"... both are the same idiots for me. Both don't grasp the historical context of the phrase.
That is not what we call "production code", even if it is strictly speaking production code. And: that code you usually don't see anyway. Unless someone is working in crafting compilers, like you:D
My argument was not "against recursion" but for recursion as basically all arguments against it are either wrong, missleading or in appropriated. Perhaps you did not see my other posts.
and likely don't want to support every protocol baked into their older software versions. That would cost basically nothing. You just keep the older libraries in the package, facepalm.
Anyway: I explain it again.
31th of december 2016, WhatsApp works perfectly. But it gives me messages since 1st of October, that it will stop working in january 2017.
About 10th of January it stopped working. No Os change on my Phone, no Software change on my phone. I did not do an OS upgrade. I did not change anything on my phone. So: there is no reason for it to stop working except the deliberate "switching off" by the company. Same with Skype.
Can't be so hard to grasp that the companies in both cases are abusing the fact that they have/operate the servers.
I can not even upgrade WhatsApp, because for that I would need to upgrade the OS first, which I'm not going to do.

As soon as you have an high enough level of wind and solar, traditional base load is no longer needed, as it is replaced by wind and solar.
