On average, hosting for Java applications begins around US$10 per month, while Python services start at around US$2 per month. Other Python advantages include the open-source nature of Python and the fact that the language s creator Guido van Rossum works at Google. Google was able to tweak the language slightly so that dangerous operations are not allowed, like writing to the file system. This prevents robust uploading services and spawn subthreads. Your app has to be pretty efficient, because App Engine will kill any thread that takes too long to run.

The swash plate cam (Fig. 14.28) is an end cam having a at-plane disk xed at an acute angle to a rotating shaft. This cam has been used for a multipiston pump whose piston rods ride on the swash surface. If a knife edge or point contact were employed, the follower would move with simple harmonic motion. However, with a more practical crowned roller follower, the follower has approximate simple harmonic motion, if the roller diameter is kept small. Swash-plate cams are feasible only under light loads, since the eccentricity shown causes poor bearing operation due to excessive de ections of the cam and its shaft.

times, exceeding the range of values the device will accept. The clock-based devices drift out of synch as the clock on the device drifts out of synch with standard time. In both cases, the servers try to keep track of device drift in order to adapt to it. Some vendors, notably of counter-based products, have developed automatic resynchronization procedures that don t require a help desk call, while some products will require a help desk call whenever they float out of synch. To date, no study has been published that compares the cost of password maintenance against that of password token maintenance or biometrics maintenance (including enrollment costs). Biometric users seem much less likely to lose the associated biometric trait, although they can encounter difficulties if a trait changes because of injury or if it changes significantly with age. Moreover, some biometric techniques provide a form of redundancy. For example, Cathy might always use her right index finger when authenticating with a fingerprint reader, but most systems will allow her to provide patterns of other fingers as well. If a bandage covers her right index finger, she can use her left index finger. Iris-based recognition can, of course, enroll both eyes in the system; the user can then use either one, which is helpful if a bandage covers one. Typically Cathy can simply provide the alternate eye and the system will recognize it automatically. If the problem requires help desk intervention, the help desk must be careful to authenticate the caller. Obviously, anyone can telephone the help desk and claim to be a vice president who needs his password reset; a well-run help desk anticipates such requests and has procedures in place to handle them. High security environments will simply have to apologize and refuse to help, though other environments can provide the help desk with dossiers on employees for authentication purposes.

At the price of high-quality photo papers, you should make the most of every square inch. Unless you want an 8 10-inch print, cram as many pictures as you can onto a single sheet of paper. If you re using Photoshop Elements, that s not easily done. Elements has functions that let you print more than one photo on a page. One of them is fine if you want to use a single sheet to make several prints of the same photo, the same size or different sizes, like school pictures. But if you want to print several different pictures on a single sheet of photo paper, Elements wastes a lot of space. Paintshop Pro does it the way it should be done. You drag photos onto a layout sheet and then position them, rotate them, and resize them until you ve got an ideal layout that fills the surface. For an inexpensive solution regardless of the editing program you use, download Photo Paper Saver from www.fpdoctor.com/pps/main/main-j-0-0.html. The shareware program $20 to register lets you click and drag the images you want to print and choose the size for each from a menu. Then the program automatically juggles the pictures on the page until it finds the layout that makes the best use of space. Figure 6-8 shows the way Photoshop Elements and Photo Paper Saver make the most, or least, of a page of expensive photo paper.
