When you suddenly not on the net, what will you do, you may check whether the router is normal, enter the router access address such as 192.168.1.1, you can log on to the success of the router can confirm that there is no problem. And when you find that the icon in the lower right corner of the desktop turns gray, the X-state, you need to check the interface is good. When checking the cat interface, you need to pay attention to a place that is the cat's indicator light! You may find that the ori

Booz Postek c168 Barcode printer has three LEDs and three keys in the lower left corner. Compared to other single LEDs and key design commercial printers, Booz C168 series recognition and operation will be more clear and simple, more humane. Booz C168 Series three indicator lights and three function key design, you can remind users of the current machine working state, and press a key to perform the required function settings. For example: Ready ligh

lock. However, it may be suspended in pthread_cond_wait () because there is also an operation to request a mutex. The Child1 function gives the use of standard condition variables: callback function protection, pending condition locking, pthread_cond_wait () back to unlock. The conditional variable mechanism is not safe for asynchronous signals, that is, calling pthread_cond_signal () or Pthread_cond_broadcast () in a signal processing function is likely to cause a deadlock. Three

Problem Description:Turn on the light problem, there is n lamp, number is 1~n. The first person turns all the lights on, the second person presses the switch with multiples of 2 (these lights will be turned off), and the third person presses the switch with multiples of 3 (where the lights are turned off, the lights on

: can not solve the problem of people, as the problem can not be solved! (Need a certain understanding) Finally someone put forward the plan, he is so calculate: 1. Suppose 1-1+1-1+...=s 2, then 1-s=1-(1-1+1-1+ ...) ) =1-1+1-1+1...=s 3, so, 1-s=s, apparently, s=0.5 The man was very clever, he knew he could not solve the problem, left the problem to the problem itself, using the contradiction to offset the results. Unfortunately, he finally raised a stupid question, he asked: if the 1 as a t

If the value is not greater than 0, the sem_wait causes the thread to block until the value is added to the Sem_post release, but before the sem_wait returns, the value value is red

---------- Android training, java training, and hope to communicate with you!---------- Today, let's talk about the traffic light system: First, design a Road class to represent the route. Each Road object represents a route with a total of 12 routes. Therefore, you have to generate 12 Road instance objects. Then a new vehicle is randomly added to each route and must be added to a collection for storage. Every second, each route checks whether the lights
