or you might use a mechanical or electromechanical governor on a coal plant.
The plants I was in (Coal fired base load) would use eletro-mechanical means to control the amount of power being applied to prime mover, in order to maintain the target RPM. (3600 in the 'States) It's an insanely complex system with buffers built in all over the place. Less power needed=less steam=less heat=less coal+somewhere to store the extra of all of those things as the upstream supply slows down. More power needed=more steam=more heat=more coal+somewhere to draw those things from as the upstream supplies ramp up.
To modulate the amount of current (in an ideal world, the voltage stays constant) being produced by the alternator they use an excitation system to change the magnetic fields on the rotor which changes the amount of current coming out of the stator.
TLDR: In a coal plant there are two systems working in concert, one to govern the speed at which the genset spins, one to dictate how much current is being produced.
Read up on generators and how demand influences frequency.
When you're done, go read some man pages.
It astounds me that someone will take the time to write a post, but not take the time to actually answer the question that was asked. How that is that insightful?
Two different purposes. Most people aren't going to learn a damn thing from reading a man page from front to back, unless you needed to run a command and don't remember the switches. Spending a half hour reading a wiki page would likely give someone a pretty good high-level understanding of a subject. To your point though, maybe a link to some material to read would have been a little more helpful. But literally googling "generators and how demand influences frequency." produces a number of links on the subject, this being the first one: https://physics.stackexchange....
Do you think there are any for-profit companies out there that aren't driven solely by profit? Mission statements sound great and all, but they are the first thing to get chucked in the trash when profits start to sink. Do you think Lucasfilm sold out because they got bored?
I think the problem (at least in my limited experience) is that an ERP is brought in to replace something that was custom built for the business. There is no ERP in the world that is going to run a business better in the eyes of the ground-level users than a custom built software.
Bitcoin Nears $17,000 After Climbing About $4,000 in Less Than a Day
You didn't even have to read the summary, all you had to do was read the headline. Show me anything else that people are willing to pay money for that has grown in price that much in one day. We can argue all day whether it's worth $17,000, or how spectacular the crash will be when the non-techies realize what they are actually buying and bail out en-masse, but that doesn't change the fact that there are currently people willing to plunk down a small fortune on nothing more than bits and bytes.
As long as he can figure out autopilot (like a real actual autopilot). It's 2017 and people still haven't figured out how to merge onto a freeway, no way in hell I'd trust 90% of the people on the road today to fly a car.
Well shit, now I've gone and done it! Some random anonymous dude on the Internet isn't going to do business with me.
As long as we don't agree, I won't do business with you.
You just summarized every consensual transaction ever. Generally people don't do business unless they can come to an agreement. If I'm trying to sell you a bitcoin, house, or a bar of gold the transaction likely isn't going to take place unless we can agree on a price.
as long as the mechanism for preventing it isn't worse than the action it seeks to prevent.
I'd argue that the government spending its finite resources to tackle an issue that really isn't really an issue is far worse than the problem itself. I typically find myself on the left side of the aisle, but this is ridiculous. There are hundreds of ways this could be solved technically, without legislation, if the markets demanded it. This is one of the things that a "free market" can fix. If enough people don't participate, this whole scheme falls apart in a heartbeat. Or if enough people bitch to a certain retailer until they put measures in place to prevent this,
the problem fixes itself.
Now if there is collusion involved, as is the case with Ticketmaster (or whoever the hell it was), I would have a bigger issue with it. It's not like e-bay/amazon are giving these bots priority/proprietary access to their systems purely for the intent of allowing scalping to take place. If they are, that's collusion and it's already illegal.
If I decide to cash out of my real estate, its value is based on its usability. If I decide to cash out of Bitcoins, that value is based purely on agreement.
I disagree. The value of either of those things is how much someone is willing to pay you for them at the time that you want to sell them. Doesn't matter if it's a house, a dollar bill, or a bitcoin.
Clearly these prices are seriously over-inflated, and likely caused by bots buying all of the virtual kittens as soon as they are available.
Call your Senator, get them working on it before it's too late.
6. Do nothing. There is no problem to be solved here. They just moved their inventory in record time.
Although, a smart retailer would do 1 and 5. If they were able to recognize this was happening soon enough, double the price for the first 30 minutes that the inventory is in stock with a giant "NON RETURNABLE ITEM" plastered all over the place. #7, profit.
Quit posting this stupid shit on Slashdot! There are a million other garbage sites people can go to read this tripe

that is NOT what your core, loyal audience wants here!
We can't, as a the Slashdot community, collectively reach the same conclusion on one single subject, but we have found the one person that feels they can represent our group in its entirety. PeeAitchPee 2020! PeeAitchPee 2020! PeeAitchPee 2020!
Comparison, quick read would indicate that an OTR truck carries about 2100 lbs of fuel at full load. https://www.smart-trucking.com... 300Gal@7 lbs/gal.
Would be interesting to get a comparison of the weight of the other major chunks, engine/trans/drive-line vs their electric counterparts.
I did an extremely small installation, a single 30-person training/conference room with lights, video, sound, all controlled by remote. We used Lutron's RadioRa equipment, I think there were 3 dimmers, a couple of toggles, a scene controller, and a wireless to ethernet (or maybe it was serial, don't remember) bridge. Once I got past the learning curve of how the whole damn thing worked I never had an issue with it.
The equipment was as dumb as you could possibly get from a technology perspective. There were no GUIs, no cloud config, no outside internet connection needed, nothing to make the installation "easy". You had to spend the time to read the manuals, experiment with the logic, and generally futz around with it until you had things how you want them. After that it just worked.
The problem is your "average" end user of such a thing isn't going to have the patience to do what I just described. They want it "iPhone easy". They want to take it out of the box, plug it in, and have it work. There is an inordinate amount of complexity involved with making something complicated that easy to use. With that underlying complexity comes bugs. I'm not arguing which one is "better", just providing an anecdotal observation. I'd love to get all my outside lighting coordinated into a "smart" system, but for the reasons you described I haven't been able to convince myself that it's worth the hassle.
Oh, never said it was a good idea. I'm just implying that FB has probably figured out some pretty clever ways to weed out "duplicate" images, even without keeping the actual image on hand in any readable form.
Really? You honestly thing a company with virtually unlimited resources didn't think of that? (Or the Parent's "changing a pixel" comment?) I realize that what they are doing doesn't follow the definition of "hash" as we traditionally think about it, where changing one bit in the source changes the hash. But I'm pretty sure FB didn't just get outsmarted by two ACs on Slashdot.

They need to keep their design team working on new things.
Like the production line that still isn't working.
Maybe they could hire some bakers to come help too. Seems about as logical as asking a designer to do it.

The problem with flat earthers, it is difficult to tell if they are trolling or really are full-on mentally handicapped.
It's entirely and utterly driven by profit
Do you think there are any for-profit companies out there that aren't driven solely by profit? Mission statements sound great and all, but they are the first thing to get chucked in the trash when profits start to sink. Do you think Lucasfilm sold out because they got bored?

Wow, the choices seem kinda limited then?
Welcome to the world of enterprise software.
what was it bitcoin achieved?

Wow. Seems like the mods are lazy today. +4 insightful for copying two words from the summary.
As long as he can figure out autopilot (like a real actual autopilot). It's 2017 and people still haven't figured out how to merge onto a freeway, no way in hell I'd trust 90% of the people on the road today to fly a car.
You mean comparing two things that achieved something nobody thought could or should happen? Seems reasonable to me.
The real question to answer, when they say GIF in their head to they hear it with a soft G like Giraffe or hard G like Guilt?

When Adam and Eve ate the fruit, it was the SERPENT who got the worst punishment of all for fibbing.
Except the serpent didn't really lie, did he?
You do realize that none of that actually happened, right? It's a cool story and all, but still fiction.
I typed a bunch of stuff after this, but no one is going to read it anyway.
There are apparently 400 sites out there that will.
