Euclidean algorithmEuclidean algorithm is also called the greatest common divisor method, is the algorithm to find two integers.Of course, can also seek least common multiple.Algorithm implementationIn fact, the implementation principle of the algorithm is that there is a b an integer two, each time a number r = a % b , and then put b into a the position, put r to b the position, recursive call.That's the gcd(a, b) { return gcd(b, a%b); } way it is.The end condition is when a%b == 0 the time is

Mechanical keyboard basically use cherry MX axis, then how to distinguish these axes, how to buy?
Classification of shafts
Currently on the market circulation of the main axis is cherry Cherry MX axis, according to color classification for black tea green. This one also has the domestic yellow axis, belongs to the Zhou Rapoo independent design production, here does not recommend the purchase. In additio
mechanical keyboard, the most important thing to pay attention to is the "axis."
In the early development of the mechanical keyboard, cherry is not the axis of the Overlord, ALPS, Omron, NMB have good shaft products appear, even cherry in the early also exist ml, MY, MX three different structure of the shaft body, MX as the most recognized axle body switch on the market, Its 30-year history is legendary.

initialization of the network can not be done, but wait until the Alps\packages\services\telephony\androidmanifest.xml In the Otastartupreceiver receive boot_completed can call up Phoneapp, and then execute its oncreate () to initialize the operation to find the net. This will undoubtedly lead to a delay in finding the net. So at this point we need to find out where to start the phonestagtesmgrservice. Here we need to focus on an action---cellconnser

Story of the "2" bandThe OPENBTS system has two highlights. One is the wireless transceiver, especially the frequency band processing, the other is the network system, especially the alternative to the traditional base station (BTS), the base station controller (BSC), the Mobile Control Center (MSC), and (HLR/VLR) alternative solutions.Say the frequency bands first, the story starts from 1894. This year, German physicist Heinrich Hertz died. The most important thing about Hertz's success in life

Today, I finally finished coding for a project that is not very troublesome and finally started the test.
The problem is that people have a lot of power, and many small details are found in the test. But fortunately, there is no big problem, which is much better than imagined.
There was a reward during the test. I bought some Alps milk sugar. I started the test, and the milk sugar test was also a good method, I don't know if I have mentioned it on t
Currently, the calibration data of ACC, gyro, and PS sensor is stored in NVRAM and added to NVRAM binregion. After the factory settings are restored, sensor calibration data recovery.
However, the sensor data in NVRAM binregion must be calibrated and saved on the production line, and is always a fixed value.
However, in normal mode, the customer needs to perform Calibration at any time and keep the latest calibration value intact.
Because the source code of NVRAM binregion and sensor daemon is n
