Even gas powered, non hybrids can get very decent millage without disregarding safety. The chevrolet cruze eco gets 43 mpg highway while scoring 5 stars on the euro ncap, it also very roomy and the interior is very nice. This is without start and stop, direct injection, and individual, computer operated valve timing (ala fiat's multiair).

Television

The Next Phase of Intelligent TVs Will Observe You 294

An anonymous reader writes "Japan based NHK Science & Technology Research Laboratories (STRL) is testing an interface which observes TV viewers, determines their interest and provides information related to the TV program in accordance with the way they are watching it. UTAN (user technology assisted navigation) TV viewing interface, as it is called, has a camera mounted on the TV which photographs the viewer and estimates the viewer's degrees of interest, concentration, etc. The information is processed by a tablet PC and recommended information is shown to the viewer. It is possible to show individual interests as well, in case there are multiple viewers."

Comment Re:Give me Laser Toner any day of the week (Score 1) 651

Well mind you, I had my first inkjet in 1997, it was an epson stylus color iis (without the color package) and it covered all my printing needs up until when I had to replace my computer with one without an LTP port, here is why:

-cartridges were HUGE, at least for today standards, one could print more than 500 pages
-The printing head came separated from the cartridge, alternative cartridges where about 4 dollars.
-Bulk ink!! a syringe, a lil mess and 500 pages more for about a dollar!

I replaced it with a canon which gets the bulk ink treatment too, however the cartridge is to small, the printing head is too easy to clog and the color cartridge is a joke. I still print cheaply but the mess is not worth it anymore. Looking for a laser now.

Calc:

Books!, get some good ones and read all theory, solve every example, do as much problems as you can and you shall pass. Particular suggestions? well I used stewart's calculus for theory, I am sure that there are better ones but it did the trick (for multivariable calc I prefer Espinoza Ramo's analysis vectorial dont know if it is available in english), those two will explain the theory quite well, try to do every doable proof for the identities you might have to use, it will help you remember them and and understand what they are about.

Buy them used, you can find the for less than a cup of good coffee, most books dont change that much from edition to edition, dont be afraid to buy a book more than five years old, get the compendium, at least with stewart's calculus you can get a book which includes single and multivariable calculus or two with each topic.

Lectures!, there are plenty of online lectures from many universities available online, I really enjoyed the mit ones available at mitocw and academicearth.org there are also lectures from berkley, I first red the book then listen to the lectures, with the mit ones there is even material such as examples and exercises available (at mitocw)

Practice!, as much as you can, concepts are sometimes easy to gasp, examples easy to solve, but many problems require certain math skill which you can only get by practicing, for this I recommend a series of books: Schaum's outlines, they are available for almost any course and provide an extensive array of solved problems to help you get the skill, dont look at them! solve them, and just when you are stuck look at the book. practice practice practice! (these books also come with a theory but sometimes too resumed and dificult to get without a proper background)

Stat:

Currently taking the course with university provided material, cant really help you that much, google a bit and I am sure that you will get some good book recommendations and adequate video lectures, there are also shaum's outlines for statistics, in this case I have found the thery available on the outlines to suffice.

Ps: you can get the books really cheap at betterworlsbooks.com dont bother with the last editions, an old book in good condition will be much cheaper and almost as good as the latest one.

Comment Re:Been caught out with faked good from Amazon too (Score 1) 447

I am fairly certain that Amazon also sold fake ipod usb adapters, the new small ones, I got two of those from ebay and they were a fairly good fake (knew before buying, after all they were 3 usd including shipping), except that all of them had the same serial number and a misspelled "desgn by apple in california".

Here the link http://www.amazon.com/Apple-Power-Adapter-iPod-iPhone/dp/B001GQ3DP6/ref=sr_1_1?ie=UTF8&s=electronics&qid=1267920282&sr=8-1 I invite you to read the reviews, for me it was no trouble this little guys being fake, I use them to power up a couple of old pda that now act just as fancy clocks and rss readers.
