Today, I'm going to hand over the time machine backup to the NAS, which was placed on an external hard drive, albeit faster than the NAS, but it's a bit cumbersome to plug in and pull out. And the NAS also has the function of real-time online and timed shutdown. With time machine, maximum data backup can be achieved.In fact, this configuration note is one side of the writing, I do not know what will be stepping on the Thunder, so the configuration process is not necessarily the most concise, jus
Today I'm going to hand over the time machine backup to the NAS, once on an external hard drive. Even faster than NAS. But every time I plug and unplug the external is a bit troublesome. And the NAS also has the function of real-time online and timed shutdown. With time machine, maximum data backup can be achieved.In fact, this configuration note is one side of the writing, I do not know I will step on what thunder. So the process of configuration is not necessarily the most concise, just to bri
The Intel 320 Series SSD has a plastic film on both sides of the aluminum shell, which is used to reduce interference and prevent the electronic equipment in the PCB board from being scratched. Intel's PCB and other brands of solid-state hard disk PCB different, single-sided has 10 flash particle bits, such a design also proves that the solid-state hard disk PCB is far from homogeneous.

In our android development, we often use the screen size to determine the ui or other purposes.In some cases, incorrect values can be obtained by obtaining the width and height of the screen based on different models. (Unit differences and mobile phone manufacturers are different)Two days ago, it was found that 800*480 was taken from a 533*320 mobile phone in the program, but some were normal. I don't know whether to pass "pixs = dips * (density/160 )
-level page. Ttnavigator will be instantiated Based on the URL as needed, which greatly saves memory.
Next, let's take a look at how URLs are mapped to classes. First look at a ing:
[Map from:@"TT: // menu/(initwithmenu :)/(page :)"Tosharedviewcontroller: [menucontrollerClass];
Then @ "TT: // menu/1/5" is equivalent to calling:
[[Menucontroller alloc] initwithmenu:1Page:5]
Tableviewcontroller in 320 is tttableviewcontroller, which

reason is that the number of candies doubled every night, equivalent to moving left 1 bits, when the binary representation of the number of 1 is unchangedIn other words, all 1 in the binary representation must be added.And only 1 of binary representations are added.So the number of binary representations in 1 is the number of candies added.1 /*************************************************************************2 > File name:code/cf/#320/a.cpp3 >

Because of the project requirements, our server requires the use of the Red Hat Enterprise Linux4 Update 4 system, so we drew a new Dell OPTPLEX 320 machine as the server, and then the problem came.
This Dell machine was originally pre-installed with Windows XP and provided with a red flag Linux5.0 desktop edition. However, we don't care about this either. We just grabbed the RHEL4 CD and started to install it. The installation took only half a minut
