生成测试数据 绘图首先需要数据。通过生成一堆的向量,转换为矩阵,得到想要的数据。 data <- c(1:6, 6:1, 6:1, 1:6, (6:1)/10, (1:6)/10, (1:6)/10, (6:1)/10, 1:6, 6:1, 6:1, 1:6, 6:1, 1:6, 1:6, 6:1) [1] 1.0 2.0 3.0 4.0 5.0 6.0 6.0 5.0 4.0 3.0 2.0 1.0 6.0 5.0 [15] 4.0 3.0 2.0 1.0 1.0 2.0 3.0 4.0 5.0 6.0 0.6 0.5 0.4 0.3 [29] 0.2 0.1 0.1 0.2 0.3 0.4 0.5 0.6 0.1 0.2 0.3 0.4 0.5 0.6 [43] 0.6 0.5 0.4 0.3 0.2 0.1 1.0 2.0 3.0 4.0 5.0 6.0 6.0 5.0 [57] 4.0 3.0 2.0 1.0 6.0 5.0 4.0 3.0 2.0 1.0 1.0 2.0 3.0 4.0 [71] 5.0 6.0 6.0 5.0 4.0 3.0 2.0 1.0 1.0 2.0 3.0 4.0 5.0 6.0 [85] 1.0 2.0 3.0 4.0 5.0 6.0 6.0 5.0 4.0 3.0 2.0 1.0 注意:运算符的优先级 > 1:3+4 [1] 5 6 7 >

onCellInfoChanged() callback is always null

问题 i am trying to get a list of all available cells the device can find. But i am stuck, as my CellInfo is always null and i don't figure why. Can someone give me a hint? There is pretty few info on onCellInfoChanged() at google. MainActivity: CellListener cellListener = new CellListener(this); cellListener.start(); CellListener: public class CellListener extends PhoneStateListener { private static final String TAG = "CellListener"; private TelephonyManager telephonyManager = null; private

并发编程之无锁

并发编程之无锁 6.2 CAS与volatile 源码之LongAdder 6.8 Unsafe 6.2 CAS与volatile 其中的关键是compareAndSet,它的简称就是CAS(也有Compare And Swap的说法),它必须是原子操作。 注意 其实CAS的底层是lock cmpxchg指令(X86架构),在单核CPU和多核CPU下都能够保证【比较-交换】的原子性。 在多核状态下,某个核执行到带lock的指令时,CPU会让总线锁住,当这个核把此指令执行完毕,再开启总线。这个过程中不会被线程的调度机制所打断,保证了多个线程对内存操作的准确性,是原子的。 volatile 获取共享变量时,为了保证变量的可见性,需要使用volatile修饰。 它可以用来修饰成员变量和静态成员变量,他可以避免线程从自己的工作缓存中查找变量的值,必须到主存中获取它的值,线程操作volatile变量都是直接操作主存。即一个线程对volatile变量的修改,对另一个线程可见。 注意 : volatile仅仅保证了共享变量的可见性,让其它线程能够看到最新值,但不能解决指令交错问题(不能保证原子性) CAS必须借助volatile才能读取到共享变量的最新值来实现【比较并交换】的效果 为什么无锁效率高 无锁情况下,即使重试失败,线程始终在高速运行,没有停歇

一、内容 Bashar was practicing for the national programming contest. Because of sitting too much in front of the computer without doing physical movements and eating a lot Bashar became much fatter. Bashar is going to quit programming after the national contest and he is going to become an actor (just like his father), so he should lose weight. In order to lose weight, Bashar is going to run for k kilometers. Bashar is going to run in a place that looks like a grid of n rows and m columns. In this grid there are two one-way roads of one-kilometer length between each pair of adjacent by side cells,
