Couplet | couplet Advertisement | webpage
Now a lot of website advertising to do in full swing, now I would like to introduce the common couplet floating advertising effect of the code use method, introduced this effect, in the 1024*768 resolution of the normal display, in the 800*600 resolution can automatically hide, so as not to cover the page affect visitors browsing content, Here is the code needed to implement the effect:
var delta=0.015 v
necessary!
② often see for example DDR2 800 and DDR3 1333 what these represent
DDR2 refers to 2 generation of memory, memory is divided into DDR (1 generation), DDR2 (2 generation), DDR3 (3 generation), of course, performance comparison, 3 generation of performance >2 generation of >1 generation. As for similar to DDR2 800 here 800 refers to the memory bus fre
Many web design in the design of the Web page layout, the interface of the width of the page design are more confused, 800*600 size and 1024*768 size of the resolution, the page should be designed to how many pixels is appropriate? The horizontal scroll bar will appear when it is too wide, Below we will explain the standard dimensions of Web design.

number of concurrent connections that Tomcat can handle in a flash. For example maxthreads=1000,maxconnections=800, assuming a moment of concurrency of 1000, then eventually the number of Tomcat threads will be 800, that is, processing 800 requests at the same time, the remaining 200 into the queue "queued", If acceptcount=100, then 100 requests will be rejected

1, on the desktop right click My Computer-Properties-Advanced-performance-settings
2, then click on "Advanced", and then at the lowest there is a virtual memory, click "Change"
3, there is a "virtual memory" dialog box, then select Custom Size, enter 800 in the initial size (MB), enter 800 in the "max

-independent Pixel (DIP)
Refers to the logical density unit of calculation, dip and specific pixel value of the corresponding formula is dip/pixel=dpi value/160, that is, PX = DP * (dpi/160)
2. DPI value calculation
For example: Compute WVGA (800*480) resolution, 3.7-inch density dpi, as shown in Figure 1
Figure 1
Diagonal pixel represents the pixel value (=) of the diagonal, dpi=933/3.7=252

the difference of DDR2 DDR3
• Further reduction in power consumption
The default voltage of DDR2 memory is 1.8V, and the default voltage of DDR3 memory is only 1.5V, so the power consumption of memory is smaller and the calorific value is correspondingly reduced. It is worth mentioning that DDR3 memory also added temperature monitoring, the use of ASR (Automatic Self-refresh) design, by monitoring the temperature of the memory particles, minimize the refresh of the new frequency to reduce tem
number of threads always kept running. If not specified, the default is used.
My simple understanding is:
The maximum number of threads that can be maxthreads:tomcat the thread pool;
Maxconnections:tomcat requests (connections) that can be processed concurrently;
Acceptcount:tomcat maintain the largest number of columns;
Minsparethreads:tomcat the size of the thread pool initialized or the Tomcat thread pool will have at least so many threads.
It is easy to mix the two parameters of MaxThreads
error match. Once a regular expression is released into the actual code, you may not notice both. Consider the example of the phone number above, which will match "800-555-4000 =-5355". Bad matches are hard to find, so it's important to plan ahead and do the testing.
or using the phone number example, if you confirm a phone number in a Web form, you may want to settle for a 10-digit number in any format. However, if you want to separate phone numbers
times. That is to say, if your company's website is of medium level, it should be estimated that 27 people have come to see it or have averaged five persons to see five times. This projection is very rough, But what I want to say is that if you don't make any effort, it's not a simple thing to get 80 or 800 trips a day, if you don't do anything.
Why are so many companies not paying attention to site visits? The reason is very simple, I take a metaph

Pulling hair: Refers to the search engine's one kind of punishment, manifests the site quantity extremely has the descent. Usually happens in Baidu.
Just a few days ago, my old version of the gold bottle Mei station was Baidu hair, and also occurred in the site of the status of Zero, but the ranking is still there. Part of the observation data is as follows

1. ResolutionThe overall width of a Web page can be divided into three settings: percent, pixel, pixel + percent. Usually in the construction of the website is the most common pixel form, the industry site is not listed outside. When we design a Web page, we will certainly take into account the resolution of the problem, technology development to now we usually use the resolution of 1024*768 and 800*600, now many of the
