, later, when you call registerReceiver to register a Matched Receiver, this Intent object will be directly returned to the newly registered Receiver. It is important to understand this.
Because BatteryManager broadcasts an intent entity of sticky, this means that you do not have to register a broadcast receiver for your program to accept the broadcast. You can simply call the registerReceiver method, when you need to add the parameter of the broadcast receiver location to upload to null, you ca
Believing that the phone's endurance problem is one of the biggest headaches for all smartphone users, the problem is not well addressed, only improved. For the recently concluded IPhone6 new product launch, we are on the launch of another mobile phone is very interested, there have been many people consulting iPhone6 plus battery How to maintain the next small series to teach you how to do.
How to maintain the IPhone6 plus
Researchers at the University of California, Davis (University of California, Davis) recently developed a 1000-core processor called "Kilocore", the world's first processor with 1000 cores. Furthermore, these 1000 cores can also be run independently.The Kilocore can execute 1.78 trillion instructions per second, at least in the processor designed by university researchers, with the highest clock frequency. This processor is manufactured by IBM and uses a relatively obsolete 32 nm CMOS manufactur
The MacBook is a long time, and the fever is very strong, so let's see how we can clean it up.
1, first, we use a Phillips screwdriver to unscrew the back cover 10 screws
2, then the first thing to do is to unplug the battery power cord otherwise it is possible to burn the motherboard, this is the power cord, we hold, pull up, next to the line with plastic
The MacBook's battery is an important part of the battery, and the number of cycles is an indicator of how healthy the battery is, according to the official, the MacBook's battery cycle is 1000 times, 1000 times after the battery life will be significantly reduced, many begi
seconds, it takes half a day to connect. In other words, the Bluetooth hardware of the MacBook Air used by our manager to cut the cake can no longer be connected to the Bluetooth HID (neither in WIN7 nor in MacOS, and other devices are normal ), do you believe it? That's why I gave my manager another 2G 4G mouse that I originally owned, and I brought it back. I don't know how this Bluetooth mouse is damaged.The level of HID and leibai is too advanced
1 Linux Time System
The most basic time unit of a computer is the clock cycle, such as command taking, command execution, and memory access. Time system is a very important part of computer systems, especially for Unix time-based systems. The main task of the Time System is to maintain the system time and prevent a process from occupying the CPU and other resources exclusively, that is, the scheduling of the driver process.

48 V mains supply technology is the future direction of data centers (1)
With the large-scale construction of data centers, users pay more attention to energy costs and efficiency. The future direction of the power supply technology of data centers must be the municipal direct power supply technology, while saving the investment and Site Occupation of traditional UPS equipment and reducing the initial cost, it also reduces the operation cost by reduc

Caffe Gadgets (1)-Visualize network structure
\quad recently studied Caffe, but as a former Windows depth user, it is a more accustomed visual interface. However, Caffe is certainly better under the Linux/os x system, because it is usually written in script that is played in the command line. So this is not intuitive, in order to be able to intuitively see the network structure, and not to see prototxt brain repair ... Visualization is important.\qua
