I worked often together with DevOps and also worked as DevOp myself. If competent people work, it works.
Incompetent people can cause havoc in any situation.
(And yes, it is superbly boring if you need another CI server and the "server guys" can not provide one... hence, you set up your won, and suddenly you are a DevOp, oops. It is so easy. Where the hate for new adequate approaches come from is beyond me. Perhaps you don't like the term... then coin your own one)
The traditional definition of baseload is the amount of power you minimum have to feed into the grid (e.g. 50% of peak) So you usually have a small set of plants that run at high load 24/7 52 weeks a year. Obviousky youncould call them base load plants. However, that is a definition coming from the grid and noch t from the plant.
However we are shifting away from that. In Germany a huge deal of base load now comes from wind.
I explained that the PM is a kind of product manager. And the SM is teaching Scrum, he is neither managing the team, nor the product, nor the people, nor the software development process (Scrum is a metaprocess).
The problem is not throtteling down, the question is: is it worth it? E.g. if you have a wind prognosis that makes you confident that you only overproduce for 2 hours, why throttle down now and power up later again? Also such negative price deals are usually amoung brothers, I sell today to you, you sell tomorrow to me.
The CF actually has nothing to do with baseload. I can have a solar thermal power plant with a CF of 45% and run it as a baseload plant... who would care or even know it?
A coal plant does not even need 3 days to power up if it was moth balled and does a cold start. A coal plant that was throttled down over night will power up with 3% to 4% of its name plate rating
per minute
. So if it is a 1000MW plant, it can change its output by 30MW - 40MW per minute.
We do Scrum, yes. However the Scrum Master is not managing the team, he is only responsible to implement Scrum, and when it us running, he is obsolet. As long as it is not running, he is more a Coach than a manager. The only thing he is actively managing (until he has made himself obsolet) are the so called ceremonies, or rituals: daily standup, sprint planning, sprint review, sprint retro, backlog grooming. Ther is a second somewhat managing role, the product owner, a tailored/lean product manager. The company is not really small, about 300 people.
Power transformers typically have been compensated to work efficiently in one direction only. As the power only flows in one direction, that argument is irrelevant...
No idea where we got lost in the discussion, but that happens easy in text based conversations:D
The car analogy was about speed, which was obvious. And in this case: speed of development.
If you can solve a programming problem in a low level language faster than in a high level language, the problem is either trivial our your skills in the high level language are not on par with your skills in the low level language.
No need to get into coolness... C was cool 1985... since we have C++98 C is no longer cool, it is outdated and only recommended for niches and for places where you have no C++ compiler or have good reasons, like space on the device, not to use it. But then again: you can program C++ 17 in a way that you nearly have no space overhead versus C anyway.
Well, we came to that "manager issue" when I said an agile team does not need and in my case has no manager.
Obviously we started about "manager" as in the sense of one who is organizing to a certain degree what a developer is doing when and how. Such a manager I don't have. And as agile coach I urge organizations to get rid of such manager positions.
But yes, I have a boss who can fire me. But he is not my manager.
The Earth's average temperature is rising and would be rising even if humans did not exist. The bold part is wrong (unless you are referring to the sun exploding into a red giant). So why are you thinking I'm mudding the water?
And second, you're wrong. Absolutely there is a performance hit if, to call a module in another language, with different calling conventions, more code is injected. No, there is not. For the caller it is completely irrelevant how the calling convention is. It does not matter if I push arguments from left to right or from right to left on the stack and then do a jump subroutine to the routine.
Calling between different languages is only expensive if one is running in an Interpreter/VM and the other is nativ AND you want to have an option to call back.
I see no reason why calling C++ from Swift or other way around should have any performance issues, but I never dug into it, if you have examples I'm eager to see them.
It's virtually certain that the Metal libraries were written in C For you it is certain, because you seem to love C:P
Maybe bees use roman numerals. It is actually not very easy to calculate in roman numbers. Precisely because they don't use positions to indicate value and have no zero. Play with a roman abacus and you understand.
That actually is also not correct... you simlpy repeat the schoolbook version.
A hive can have many queens, albeit it is rare, each with her own state. Often more than one new queen is born, hence many queens swarm out. Depending on many factors, bees also fly out alone after they got seeded by drones.
I felt some sadness about losing half the bees in that hive, Well, you could have offered a nice box for her to fly in, or simply migrated her by hand into a different box (that is how most bee breeders do it here).
In the winter, they cluster together for warmth in the "winter cluster", which slowly migrates across the comb, Actually when the winter time starts, the queen is breeding special warm up bees (and most of the remaining stock dies), usually about 50 or so bees that have very short wings but much bugger muscles than the ordinary workers. So they produce a considerable amount of warmth.
Many if not most people start counting at 1, not 0. It would be pretty pointless to start counting with 0, if that is indication the "first item in the basket", how would you count then items in an empty basket? Invent yet another meta zero? Like epsilon? And then in 50 years we have the same discussion again: most people start counting with 0, not with epsilon
There is no year 0. 1BC was followed by 1AD. There is no temperature 0 either, there is the range from -1 to X and from X to +1, just like with BC and AD, and X is zero. Zero is a point, a mark on a meter, not a length or period.
People in many countries still say "twelve oh five" instead of "zero oh five" for five minutes after midnight, to avoid the zero. That is wrong again. They don't avoid the zero. They count like they are taught, they have two periods 12 hours long, one is the AM period, the other is the PM period, wow that was easy again.
I guess some scientists are simply to dumb to grasp what the concept of zero actually means.
Most known number systems have no zero, and beyond that don't even have a number system that is comparable with our decimal, octal, hexadecimal or binary systems.
E.g. the roman, greek and hebrew numbers where simply other usages of letters, M for 1000, L for 50 etc. The "invention" of the "zero" made it possible to have number systems based on digits. Where every position of a digit has a different value, you all know what I mean.
There most likely never was any man who would not grasp that an empty basket is less full than a basket with one item inside, or ten.
That smart animals, and that probably means most animals above the level of a slime worm, can distinguish empty from not empty, does not mean they count in a decimal system and use a zero.
The Earth's average temperature is rising and would be rising even if humans did not exist. That is wrong. They would swing back and forth, like they always did.... This is not in dispute. Obviously there is nothing to dispute about the fact that you are simply wrong.
Molten salt batteries only store heat, and hence you can basically only use them to heat houses or, if you want to generate electricity from it, you lose 60% due to thermodynamics.
It makes no sense to use excess ELECTRIC POWER to heat up molten salt storages, unless you have absolutely no other option.

For course, it never actually WORKS that way
Of course it works that way.
but that's how the vendors tell me it should work
Which vendor? Since when do you need a vendor? Typical deploy chains are all open source.

Adding storage does not change the capacity factor. It only helps in using otherwise useless power (overproduction).
Yeah, it is possible, but calculations like multiplication or division were usually done by math geniuses in their mind.
I guess if you simply 'grasp' two numbers like vii and viii you simply add them in your mind, too, and then rewrite them as xv.

The numerical zero exists thousand(s?) of years longer than a 12 hour numerical clock, which we have how long? 200 years?

No, if at all they borrow it from the "preceding 12-hour mark!"

How do you come to the stupid idea they had no way to write "none"?
