So if you go strictly by the view rate, 13 million. That extra cost for a $1,000,000 advertisement would be a whole 7 cents. Since most adds are well under $1M it would be even less.
That big dark cloud, at least the dark part, is called soot. It is simply carbon. As emissions go the fact you can see it is by far the least of your worries. Worse are things like sulfates, which you can not see. And is why all diesel sold on the US for vehicles is low sulfur.
As for the emissions of a gasoline engine. Those emissions are much higher, and much more deadly. And comes mainly not from the gasoline, but its additives. This is why we regulate gasoline engines so much.
The issue is we can only tell when one is about a day out. Many times we can only see them as they are leaving, not aproaching. It is actually a fairly common occorance. You can see them at http://www.spaceweather.com/. Since the begniing of the year there have been 5 that have come close enough to actually be of note.
What the author fails to realize is that the limiting factor on a SAN is most often the host itself, not the disk. A single disk my not have the IO, but an array most certainly does (depends on array). A standard, 33 MHz PCI bus can only transfer 133Mb/s (theoretical max). Even faster buses still do not match the I/O speed or throughput of a SAN.
The limiting factor on a PC is that southbridge chip, not the storage. The vast majority of the systems typically connected simply can not push the I/O fast enough out of its ports. It is not waiting on disk, it is waiting on the IO of its bridge chip and bus. Of course putting it on a ram disk is faster. RAM sits off the north bridge and therefore has better throughput to the CPU.
This is more a limit of bridge chips and PC architecture then the speed of a SAN.
Lets see how far we can take this.
I demand, any PowerPoint slide I created that was later re-used, a cut of the quota profit sales received.
I demand, any spreadsheet I have made as a work for hire, a royalty anytime it is updated.
Does anyone here build houses? Make cars? Build anything that was sold to someone?
Living in Texas, with oil and gas, wells I can personally attest to damage done by service trucks to our road. This is due to to constant need to move the product to market, or service the water that comes from the wells (yes gas and oil wells produce water too).
I have seen these trucks that carry the crude oil from gas wells get into accidents. I have seen bridges totally destroyed from burning oil under them (concrete breaks down under the extreme heat).
Do we write about the millions of dollars in damage our oil trucks create yearly? Or do we single out a few accidents in trucking, carrying oversize loads instead.
Do we even hear about the oversize building moments that tie up traffic? Do we hear about the daily fatal accidents from truck accidents? Or do we single out a few trucks that just happened to be carrying wind turbine parts?
Hard drives do not write to the *exact* same position all the time. Additionally when they do so they effect more then the precise amount of magnetic medium below the write heads. It is technically feasible (with modification of the firmware on the drive or physically removing platters) to half step the read heads and read the spaces next to where data was written.
Devices that do this generally take one drive and attach another that can hold the recovered data. A simple search in your favorite search engine with "forensic data recovery" will revel companies that can do this and hardware available for the task.
A CFL contains about 5 mg of mercury, about enough to cover the point of a ball point pen. Let's say it breaks in a room that has a volume of about 25 m^3 (which is about a medium sized bedroom). The entire 5 mg of mercury vaporizes immediately (an very unlikely occurrence), resulting in an airborne mercury concentration in this room of 0.2 mg/m^3. This concentration will decrease with time, as air in the room leaves and is replaced by air from outside or from a different room. As a result, concentrations of mercury in the room will likely approach zero after about an hour or so.
Even with these relatively conservative assumptions, this level and duration of mercury exposure is not likely to be dangerous, as it is lower than the US Occupational Safety and Health Administration (OSHA) standard of 0.05 mg/m3 of metallic mercury vapor averaged over *eight* hours. The EPA recommends that (1) you immediately open windows to reduce mercury concentrations inside your home; (2) you do not touch the spilled mercury; (3) you clean up the broken CFL glass carefully and immediately (but not with your hands or a vacuum cleaner), and (4) you wipe the affected area with a paper towel to remove all glass fragments. Please note it is the glass they are worried more about then the mercury.
The issue with mercury in the CFL bulbs is not one of it breaking in your house. It is what happens when we put millions into landfills.
MacOS 10.5 and 10.5 server are UNIX03 Single UNIX Specification certified. It meets the criteria for UNIX.
It passes POSIX certification. It has a shell environment. And it has base C header definitions.
It is UNIX certified. But UNIX is a certification. And as such so are AIX, HP/UX, SCO, Solaris, Tru64, and z/OS.
