allows developers to quickly get such important information when they read the code by indenting.
We can also find that. Widget-heading's declarations are arranged according to their dependencies:. Widget-heading is the line element, so we add the font-related style declaration first, followed by the other.
Here is an example of not splitting into multiple lines:
CSS code copy content to clipboard
. T10 {width:10%}
. T20 {width:20%}
. T25 {widt

Widget, because the former has a more indented style set than the latter. This allows developers to quickly get such important information as they read the code by indenting it.We can also find that t
specification can fit the theme several sets of color matching, only expands the theme, does not increase the color matching, many sets of themes match a set of colors, lets the theme use without limit.

Allow design and development to deliver information quickly. Determine the code for 10 sets of colors and define the color values by category. The color values for each set of themes may be different, but the numbers must be the same, such as tex

U disk is a common use of mobile devices, but U disk features far more than you know, this does not, U disk also has this function-settings so that the computer can only be inserted into their own U disk to start. Now let's introduce the implementation process of this technique:
First, to determine the disk of U disk, you can plug in your USB disk, and then you can see the letter, this step is very important;
Second, in the U disk to create a file, file name and extension are arbitrary input,
Use of online Banking friends know, in order to ensure the safe use of funds, Chinese banks will generally use U disk as a way of encryption, only the use of the bank's U-shield to enter the network silver system. Inspired from here, in order to make their own computer security, to avoid others casually open their own computer to see their own private information, can you do a U disk, only the use of U disk to start the computer, the following said a simple U disk to start the computer Setup met
Can the computer be plugged into its own USB drive before it starts, or shuts down automatically after it starts? The following are the steps to achieve this effect:
1. First determine the USB disk letter, you can plug in your USB drive, and then you can see the letter, this step is very important, if the letter is wrong, then let your computer sleep;
2. Create a file in the USB drive, file name and extension are arbitrary input, such as the file created here is 123.LJ;
3. Create a batch file
When we use a computer, we inevitably store something more private, and also do not want to be seen, to the computer password bar, the other people want to really ask up still have no way not to tell, think a lot of methods, finally feel or think with a U disk to the computer encryption more reliable, insert a U disk to boot, without U disk you do not bother, The following small series to share with you how the specific is done
How to use USB disk to encrypt computer
1. Find a U di
The specific encryption methods are as follows:
1. Find a U disk, and then in the inside a new file, as to what everyone can casually come, file name and anything is not limited, small series on the example of. txt.
2. Create a new Notepad on the disk of your computer, copy the Ifnotexisth:.txtshutdown-s-t10-c "You cannot use the computer" to Notepad, and change the suffix name to. bat Save as a batch file; It needs to be noted that H
First, to determine the disk of U disk, you can plug in your USB disk, and then you can see the letter, this step is very important;
Second, in the U disk to create a file, file name and extension are arbitrary input, such as the creation of a file of 123.LJ;
III. Create a batch file on the local disk (saved as. bat with Notepad), which is the following line statement:
Ifnotexisti:123.ljshutdown-s-t10-c "You can't use this computer"

, but persistence will be a fatal flaw
2. Data persistence New alternatives may not bring an intrinsic boost, unless the application begins to split the raid against its design to provide a dec-like effect, and the rack and layer layouts need to be designed as part of the system Design for RV and mitigation Bit-error speed may help improve performance. If the application can correct some bitwise errors and retry those that cannot be repaired, the system's IOPS will increase significantly second,
Although Apache has a stress test tool AB, but AB is too simple to simulate real web access, we're going to use a more powerful web stress test tool--siege (English original intent: mobbing).
First, do the installation:
wgetftp://ftp.joedog.org/pub/siege/siege-latest.tar.gz
tar zxvf siege-latest.tar.gz
cd siege-2.67
./ Configure make
make install
Once the installation is complete, you can start the stress test.
