775 heatsink

Many laptops in the summer will appear the notebook temperature is too high to cause computer crashes, so in the summer when the computer to take some cooling measures is very necessary. Many users will use notebook heatsink to cool the notebook, but many people may not know that the Windows 7 system also has its own cooling measures. The power plan for the WINDOWS7 system has improved a lot, and we can use the Windows7 three power modes to cool the n

speed and target temperature, other parts can be adjusted according to demand, the default fan speed is too conservative. Video card parameters: As the first work of the AMD generation, RX 480 was placed in high hopes, with 14nm of advanced technology and a new Polaris architecture, RX 4,801 has become the market focus. Comprehensive beyond the GTX 970 R9 390 performance, in the DX12 game is more comprehensive than the GTX 980, 2000 of the price undoubtedly has a pretty good price.

Fan blade "Eccentric" is the main cause of noise. The quality of the fan, the center of its fan blades on the axis, operation is very smooth, the noise is very small, and the inferior fan, often there is a certain deviation, the center of gravity is not in the axis of the "eccentric", such a fan turned up, the equivalent of an oscillator (oscillator is in the motor shaft plus an eccentric wheel), With the use of the longer time, fan bearings gradually wear, or fan

MySQL numeric data can be roughly divided into two types: one is an integer and the other is a floating point or decimal. Many different subtypes are available for each of these classes. Each subtype supports data of different sizes. MySQL allows us to specify whether the values in the value field are positive or negative or fill with zero. The table lists various numeric types, their permitted ranges, and occupied memory space. Type size range (Signed) range (unsigned) purpose TINYINT 1 byte (-

(), remember that each value to be displayed must correspond to its own format specifier, and the type of the displayed value matches the specifier. It is a good habit to initialize a variable when it is declared. Although not doing this, there is no big problem, but there is always a chance to have unexpected results.

Title, using PHP and sqlite3 to build a small application, using Nginx as a reverse proxy server, spawn-fcgi as a fcgi service, the database and PHP and static files are not in the same directory. Now Nginx and spawn-fcgi both use nobody user work, if the database directory can not read/write, PHP will prompt can not open the database ... (This is probably the error), so you have to set the permissions of the database directory to 777, and the question is, is this really okay? The online search
