Q. I've been pondering this forever. It keeps changing. So who is strong King Cold, Broly, Cell, Buu, Baby, The Androids(before they turned good), The Saiyans(before the turned good), King Piccolo, Freiza, Cooler, Garlic Jr. Thaks for your help.
A. Cell is perfection endowed with the DNA of the other z fighters and able to use their attacks.Cell also has more potential than a saiyan because of his ability to regenerate which he got from Piccolo makes it easier for him to survive near death experiences and his saiyan DNA allows him to get stronger and stronger after surviving near death experiences. Cell also was able to learn Instant Transmission after blowing himself and Goku up and absorbing some of Goku's cells imagine if he had learnt Spirit bomb. Gohan defeating cell to me was BS, when Cell regenerated and used IT to get back to the battlefield he should of blasted Gohan with the death beam and killed him instead of Trunks.

A. Function & Price
The reader types can be distinguished as follows:
Pen type readers
Pen type readers consist of a light source and a photodiode that are placed next to each other in the tip of a pen or wand.To read a bar code, the tip of the pen moves across the bars in a steady motion. The photodiode measures the intensity of the light reflected back from the light source and generates a waveform that is used to measure the widths of the bars and spaces in the bar code. Dark bars in the bar code absorb light and white spaces reflect light so that the voltage waveform generated by the photo diode is a representation of the bar and space pattern in the bar code. This waveform is decoded by the scanner in a manner similar to the way Morse code dots and dashes are decoded.
Laser scanners
Laser scanners work the same way as pen type readers except that they use a laser beam as the light source and typically employ either a reciprocating mirror or a rotating prism to scan the laser beam back and forth across the bar code.As with the pen type reader, a photodiode is used to measure the intensity of the light reflected back from the bar code. In both pen readers and laser scanners, the light emitted by the reader is tuned to a specific frequency and the photodiode is designed to detect only this modulated light of the same frequency.
CCD Readers
CCD readers (also referred to as LED scanner) use an array of hundreds of tiny light sensors lined up in a row in the head of the reader. Each sensor measures the intensity of the light immediately in front of it. Each individual light sensor in the CCD reader is extremely small and because there are hundreds of sensors lined up in a row, a voltage pattern identical to the pattern in a bar code is generated in the reader by sequentially measuring the voltages across each sensor in the row. The important difference between a CCD reader and a pen or laser scanner is that the CCD reader is measuring emitted ambient light from the bar code whereas pen or laser scanners are measuring reflected light of a specific frequency originating from the scanner itself.
Camera-Based Readers
2D imaging scanners are the fourth and newest type of bar code reader currently available. They use a small video camera to capture an image of a bar code. The reader then uses sophisticated digital image processing techniques to decode the bar code. Video cameras use the same CCD technology as in a CCD bar code reader except that instead of having a single row of sensors, a video camera has hundreds of rows of sensors arranged in a two dimensional array so that they can generate an image.
There are a number of open source libraries for barcode reading from images. These include the ZXing project, which reads one- and two-dimensional barcodes using Android and JavaME, the JJIL project, which includes code for reading EAN-13 barcodes from cellphone cameras using J2ME, and Zebra (Changed name to ZBAR?), which reads various one-dimensional barcodes in C. Even web site integration, either by image uploads (e.g. Folke Ashberg: EAN-13 Image-Scanning and code creation tools) or by use of plugins (e.g. the Barcodepedia uses a flash application and some web cam for querying a database), have been realized options for resolving the given tasks.
Omni-Directional Barcode Scanners
Omni-directional scanning uses "series of straight or curved scanning lines of varying directions in the form of a starburst, a lissajous pattern, or other multiangle arrangement are projected at the symbol and one or more of them will be able to cross all of the symbol's bars and spaces, no matter what the orientation."
Omni-directional scanners almost all use a laser. Unlike the simpler single-line laser scanners, they produce a pattern of beams in varying orientations allowing them to read barcodes presented to it at different angles. Most of them use a single rotating polygonal mirror and an arrangement of several fixed mirrors to generate their complex scan patterns.
Omni-directional scanners are most familiar through the horizontal scanners in supermarkets, where packages are slid across a glass or sapphire window. There are a range of different omni-directional units available which can be used for differing scanning applications, ranging from retail type applications with the barcodes read only a few centimetres away from the scanner to industrial conveyor scanning where the unit can be a couple of metres away or more from the code.
Omni-directional scanners are also better at reading poorly printed, wrinkled, or even torn barcodes.

Is it really bad to put two phones next to eachother?
Q. My mom always tells me not to let our phones touch because if they do, they'll break eachother. But I'm not finding anything about it on the internet. Is it true?
A. No, I don't believe that is right.
Here is an example why I think its not true: Samsung wouldn't of created S Beam and Android Beam (Google?) if the phones broke if they were put near each other

Why is my internet so much slower on my laptop?
Q. I'm with virgin, both my computer & my laptop are connected to my via wireless connection. But my laptop gets but a small fraction of the speed my computer does.
Any ideas on how to sort this out?

A. I assume that although you say both the laptop and desktop use a wifi connection that they are not situated in the same place. It is likely that the signal strength will vary in different positions in your house. If the router supports the latest draft n wifi standards and so does the wifi adapter in your desktop then check that your laptops adapted supports 8011n too. If it only supports earlier wifi standards like 8011.g then this is much slower and the reason for the difference.
If the wifi chip in the laptop also supports the 8011n wifi standard then there are several things that can affect wifi signal and things you can do to try and improve things
To start with the basic rule is to position the router as high and as centrally as possible in your house.
1] Try changing the broadcast channel from the wireless setup interface for your router/modem.You can normally access this by typing "http://192.168.0.1/" into your browsers search bar and then look for the wireless settings menu.
You don't say if your router can use the 5GHz frequency or just the 2.4GHz. The best channels in the 2.5GHz spectrum are 1,6, 11, or 13 as they have less overlap with the other channels.
There is a useful article here about how to get the best performance by selecting the best channel.: http://www.howtogeek.com/howto/21132/cha�
If you have an android smarthphone, or a friend does, then install the Wifi Analyzer app free from android market and use it to scan for the best channel and change your routers broadcast channel accordingly. This app will aslo show you all the wifi signals in range that your neighbours are using, so you can select a different channel to them, making a stronger signal for you. https://market.android.com/details?id=co�
2] You can use a tool like Nirsofts totally free WirelessNet View to look at all the local wireless signals that are within range and may be competing with your own router and interfering with reception. from here: http://www.nirsoft.net/utils/wireless_ne�
3] You can buy a Wi-Fi booster like D-Link 645 Smartbeam, here: http://www.amazon.co.uk/D-Link-DIR-645-W�
Devices such as these can actually boost the wifi signal by using multiple beams that bounce of the walls and are intelligently directed toward whatever device [smarhphone, laptop, tablet] you are using on wifi.
4] If your using the 2.4GHz frequency and not the 5GHz then other devices that use this frequency band can alsso interfere with your reception [eg baby monitors and microwave ovens use 2.4GHz]. Try and make sure that none of these devices are situated between your router and your wifi receiver eg laptop, tablet, smarthphone etc
