Laptops energy consumption: save or not

Network interfaces and USB

We suppose sitting in a cafe in an airport or on the many of us think about energy consumption of Wi-Fi. But when we copy data from flesh card we don't think about it at all. But it is unjustified.

If you sit with turn on Wi-Fi it practically does not consume energy. If you use Internet during it the results change a few ??“ data flow will be low.

And if you will start to copy a film from one laptop to another using Wi-Fi the energy won't consume a lot. It's seen from the results.

The time of the unmanaged mode of the mobile computer when max Ethernet loaded

Viewing this diagram it is possible to think that Ethernet needs more energy for operation. No, it does not at all. We explain these results with more serious loading of the hard disk. When we tested Wi-Fi, the speed of data copying was not more 20-22 Mbit/sec (connection was set through the 802.11g standard). And with the Ethernet the speed was 80-85 Mbit/sec. It is necessary to think that Wi-Fi 802.11n standard is able to discharge the accumulator quicker than the previous releases of Wi-Fi standard. In our article "Unwinding Home net Wi-Fi" we've tested it speed and it was higher.

USB is not the most saving interface. Constant copying from flash card to the hard disk and back to front is able to reduce the operation from 30 to 80 minutes. It is too considerable for such a insignificant operation.

Yep! I find what you're saying to be true, at least in the mjtroiay of cases. Considering the years of research and developement, not to mention huge wads of cash, gone into developing both the hardware and the code to control it, some things are better left in-house. And I serioulsly doubt that your coffe would taste any better should your microwave oven run Linux. Nevertheless the call for free code has never been louder than it is today, arguably voices were louder in the sixties, but that was for free love / drugs / whatever, they did not care about code back then, that was military stuff. And, yes, the free code has not only a niche to fill but also a market, these are though largely concerned with exstensions to available technology. How about interfacing your server farm to a display system? Your RAID array to your printer? Hell, how about connecting your toaster to the coffee machine, and the fridge, and to your alarm clock for a timed, ready to eat brekfast?The point is that there is great benefit to be found in leaving your options open, now this may not necessarily mean open code but at least developing coherent standards. Cue the magic teenagers. As long as they have handles to grab they may yet be able to have your breakfast ready the minute you're human enough get out of bed, but leaving your code open is like telleing the world Hey! Put me out of business will ya! .No seriously, I believe that the call for open code for systems, best developed in-house with complete documentation of the involved technologies is a cry from a generation with hubris, not to mention used to getting the way they want whenever they want it . Bloody communists , some may say. Well, I'm inclined to agree. If you find the technology to be inferior you'd be better off calling in some hardware professionals (if you're not one of those as well), develop the product, insert your own code, and pretty soon you'll be running to the patent office and fighting neverending court battles to retain your livelihood. You see, now you're like that corporation you wanted to open their code for you, and you're afraid of competitors buying some other teen's knowledge to throw you out of business.Well here's a tip. Let your hobby stay a hobby. If you're confident enough that your solution is better, go into business and prove that it is.And if your proof is good enough I may one day wake up to a set breakfast without having to hire a Polish maid.Oh yeah, I'd probably still be late for work

Could you coseidnr putting your book trailers on teacher tube and some of the other book trailer sites? Most schools block youtube and so we can't use the trailers with the kids or linked to our book blogs.
