Solar PV generates DC, which gets inverted to AC. Cheap inverters generate square-wave AC, less cheap inverters generate stepped or modified square wave AC, and even less cheap inverters synthesize sine-wave AC, just like you're supposed to get from the grid. What I've seen on an oscilloscope of the output from my "sine-wave" inverter looks more like a *lot* of tiny steps, but it looks more like a sine wave than stepped square wave inverter output.

Not that you're allowed to attach a square wave inverter to the grid here - it's got to match phase to begin with, and disconnect when it detects the grid has gone down.

From 0% in heavy rain, to ~10% under heavy cloud with no rain, to ~50% whenever a single cloud crosses the sun - so it's really too variable to make broad statements. There's some historical data available - my own charge controller keeps 30 days of data, and if I could be arsed, I'd regularly download it to a spreadsheet - that way I'd have years of daily datapoints, so detailed reports are do-able and could be correlated with daily weather observations, I just haven't bothered.

I'm off-grid, but my charge controller is capable of graduated supply, i.e. dump all the available current into the batteries until they reach 30 VDC, then moderate the current from the panels to maintain the a batteries at 28 VDC ("absorption" phase), for 2 hours, then further moderate the current to maintain the batteries at "float" - 27.4 VDC. I'm not sure how it does it, but it *doesn't* involve dumping the excess into a heat/energy sink.

I'm not an electrical engineer, but couldn't grid-tied houses use some technology to reduce input to the grid based on either a signal from the grid itself, or based on local factors such as overvoltage in the grid?

When you use the phrase "the reality is" in your argument, then your argument is weakened (I was going to reiterate "it's a crock", but that's a catchphrase). Catchphrases don't make your argument more compelling, rather the opposite.

So tell me this: why is the concept of "pay peanuts, get monkeys", and other arguments that are used to justify the excessive payments (salaries+bonuses+stock options, etc) to high-level management, not applicable to those employees lower down the ladder? Are you suggesting that paying your worker drones more - even significantly more - than the current market *won't* have a positive effect on the company?

1. Employees will now be less likely to leave - and require replacement, which is a cost to the company.
2. Most employees will return the benefit in increased productivity - acknowledging there will always be those at the ends of the bell curve who won't.
3. I get the impression that some see this as bad, or a failure of capitalism or a failure of the free market, or they're finding *some* reason to criticise it. If a CEO decides to pay his employees more, let the free market sort it out. Why does it bother you?
4. It's likely to drive pay rates up generally. There'll be more pressure to increase pay rates, and other companies will look at this company to assess whether it can be justified or rejected (amongst other reasons, of course). Isn't that one of the mechanisms of the market?

I think this is a great idea, not only for the employees and the company, but also to observe the effect it has on the market generally. I'd use the phrase "stirring up the hornet's nest", but that's a catchphrase, and it would weaken my argument.

We've already got a lot of roads - where would we need to build new ones, if there's a collapse?

There are existing roads connecting our major centres - granted, they'll need maintenance, but that's mostly patching, as opposed to kilometres of new roads - so why would we need more than maintenance-level stocks of tar and asphalt?

Well, I must be doing something wrong, then. Start, run, taskmgr, right-click, run as administrator, right-click {AVG/Trend Micro/McAfee/Symantec} whatever their core process is called, "end process". "access denied". Check again, the account for said process is SYSTEM. Click start, run, services.msc, right-click, run as administrator, locate service/s, right-click. properties, can't stop 'cause greyed out, select "logon" tab, service uses SYSTEM account.

Start, run, regedit, right-click, run as administrator, HKLM\System\CurrentControlSet\Services\{whatever}, lo and behold, the only permissions are for CREATOR OWNER and SYSTEM.

The software installs so that Administrator does not have permission to terminate the service (without tickling permissions in the registry beforehand). AVG, McAfee, Trend Micro and Symantec DO NOT inform the user that they or Administrator will not be able to start and stop the services.

Comment Re:For when you're too cheap to buy two monitors! (Score 2) 187

There are some situations where 2 monitors are necessary. I do a little video editing - 1 screen for the controls, and a second screen for the actual video. I can't afford a reference monitor, so I just use a good quality LED/LCD screen calibrated as best I can.

You can't edit video efficiently on a single screen, even a big one. There's just too much else on the screen to allow a decent sized window for the actual footage.

'taint my code. I'm trying to set up a simple, open source digital cinema package generator - http://dcinemaforum.com/forum/...

I want to make it possible for local independent producers to put together a DCP so it can be projected on our community digital cinema system. The server ONLY accepts DCP, so if you've made a short film and want it shown, I have to do a dance with a DVD player and the projector, instead of being able to use all the nice automation provided by the d-cinema server - things like sponsors' slides, "please turn off your mobile phone", automatic aspect ratio selection, and so on.

Anyway, I've tried the open source workflow on 7 linux distros running as virtualbox guests - Elementary OS (recommended), debian, mint, ubuntu studio, Fedora, OpenSUSE, and Mageia. NONE of them has provided a smooth run - some of the open source packages come as binaries, some need compiling - I have no problem with that, but each linux distro has thrown some obstacle in the way, and it's mostly been compile failures because something somewhere expects to write to some directory for which it doesn't have permission - even when using "sudo make". I "su" then "make" and it works.

And why is third-party software allowed to install and run in the SYSTEM context? Even Administrator isn't allowed to terminate them.

If McAfee et al were nearly as good as they like to claim, I wouldn't have to uninstall them to run a decent malware scanner (after they've let ukash in), instead of just stopping them.

Yes, I know they usually have a "suspend protection" option, but I need it out of memory completely, and some of them still start in safe mode.

Well, there you go - it's 19:55 here, and Legend of Korra Book 3 just went on - the TV went on, the sound system went on, there's more lights on, and the battery voltage dropped to 24.2. Don't want to let it get lower, so the generator is going to run for an hour or so, just to keep the battery voltage up.
