Comment Math issues (Score 1) 466

Not sure where the math came from in the OP but...

100W * 0.33 * 0.50 * 0.95 * 0.50 = 7.8

This clearly is lower that 16W

Might have to look more clearly at the article and see where the discrepancy arises.

Also the OP forgets that the quoted 67% includes electrical generation. ie the turbine.

And a typical phone charger (a Switch Mode PSU) will have an efficiency > 75%. So our calculation becomes:

100W * 0.33 * 0.95 * 0.75 = 23.5

In the end this reduces the cost of software to the customer.

Customer benefits by having ready access to a database of information produced by other users (more expert than any front line help desk).

Vendor benefits by not having cost overhead of front line support infrastructure.

Everyone benefits by having honest information exchange.

Vendor developers/consulting team provide secondary support and expert knowledge as appropriate.

This is a win/win for all involved.

Is this akin to the "To help the environment, please reuse your towels" sign in hotel bathrooms? Sure, we know this is really to increase the profits of the hotel. But in a free market with open competition, these figures ultimately produce a cheaper product for the consumer.

Thoughts?

Sorry, but PC manufacturers have been putting out hardware that can be damaged by software for years. CPU overheating caused by bad drivers is one area where this appears time and again.

However, there is no reason that the PC, running a supported OS, should allow an application to damage the hardware in any way. That is either bad OS design or bad hardware design or both.

Watching 'Castle' the other night. Enjoying it for the accurate, serious show that it is. Beckett indicated the entry wound was too big for a 9mm round. Had to be something bigger. They later found a .357 which was the right size.

25.4*.357 = 9.07mm She has a good eye. Actually she has great looking eyes.
