Today, developers continue to develop and deploy applications that use the lamp (Linux?, Apache, MySQL, and Php/perl) architectures. However, server administrators often have little control over the application itself, because the application is written by someone else. This article focuses on tuning the database layer to achieve maximum efficiency. There are 3 ways to speed up the running of the MySQL server, from low to high efficiency: Replace the problematic hardware. Tuning the MySQL proc

Each of the good color palette works are repeatedly carved and carefully beautified. Need to take pictures of light, color, detail and other parts in the most beautiful way to present. It may be time-consuming to operate, be patient. Original Final effect 1. Copy a layer. Look at the picture as a whole, feel too dark, and there are some details of the backlight on the face. So dot tool bar image-adjust-dark harmonic high light, default. If you feel too gray, properly r

Monochrome pictures are quickly replaced by channels, replacing them with less-colored pictures. Later use the Color palette tool can quickly turn to their desired monochrome, and then fine-tune the high light and character color can be. Original 　　Tutorial Final Results 1, open the material picture, press CTRL + J to copy a layer of background layer. Enter the channel panel, select the green channel, press CTRL + A all se

functions do not establish a query cache. PHP is very fast to establish connections, all of which can be used without a connection pool, or it may cause more than the number of connections. Of course, without the connection pool PHP program may also be The number of connections is full, such as @ignore_user_abort (TRUE); Use IP instead of domain name to do database path, avoid DNS parsing problem 11. EndYou will find that after optimization, the performance of the database is i

and DELETE statements, SQL Server is going to maintain your nonclustered indexes. For your database, you just created an index of "pure" wasted space. On the other hand, you have satisfied the query optimizer by eliminating the missing index recommendation. But this is not the purpose: the goal is to create an index that will be used again.Conclusion: Never trust the query optimizer!SummaryToday's article is a little controversial, but I want you to show it to you, but when you create an index,

Test Apple's new iPad Apple's new product launch conference was held on time at on July 15, March 8, Beijing time. The debut of brand new Apple TV, Apple iOS 5.1, and Apple iPad also failed to meet the expectations of global consumers. The most eye-catching star of this Conference is naturally not Apple's new iPad, and the six major upgrades of this new tablet ar

the host (using winscp, you need to install openssh on the IPAD) and analyzed it using IDA disassembly. However, IDA does not seem to have a function similar to OD that uses real-time Assembly commands as machine code. Therefore, you can only query the ARM manual and convert the required assembly code into machine code bytes (so that you can search ). I wrote the required assembly code inline assembly to the first_ipad_view Program (that is, the prog

It's worth noting that the lowest speed and the highest speed 2, the wrong scan is to sweep the hard drive is not bad, if the hard drive on the bad road will lead to the system of the phenomenon of the crash.

in computer hardware, compared to the graphics card, CPU, motherboard, hard disk is one of the most easily failed hardware. Then the hard disk stores our important data, so we usually need to use some professional hard disk tools to check the health of the hard drive to back up the data in a timely manner. For HDD detection tools, the most current use is HD Tune HDD Detection Tool. Next, this article with the computer small white friends share under H

The main idea: give n points, ask you to go from the leftmost point to the rightmost point, each point must be traversed, and each point can only walk once, ask the shortest distance to formThe idea of solving a problem: using DP[I][J] to indicate that the first person walked to the point I, the second person walked to the first J Point and had traversed the shortest distance of all points of 1–max (I,J). Because dp[i][j] = Dp[j][i], so we set i > JThen there isWhen J When j = = i + 1 o'clock th

print the result to the standard output from the beginning of a line. The tour length, a floating-point number with the fractional digits, represents the result.Note: An Input/output sample are in the table below. Here there is the data sets. The first one contains 3 points specified by theirx and y coordinates. The second point, for example, has thex coordinate 2, and the y coordinate 3. The result for each data set was the tour length, (6.47 for the first data set in the given example).Sample
