Schedule can realize the function of the timer, is to do something every once in a while, schedule caller is a node, all nodes can call the schedule function, parameters need to pass in a function (Schedule_selector a new selector), In the function can complete the collision detection and so on function. Here is a concrete look at the use of this function bar.
To review the test Bo, re-pick up the vocabulary book, the back of the year, the back of the GRE word is deeply benefited from this recitation method, but, each time is their own manual writing schedule (is similar to the online various "XXX fix GRE word" schedule).
Such as:
wrote a MATLAB script that automatically generates a Ebbinghaus memory back word schedule
OriginalIn Linux, a single processor is also a multi-threaded processing signal, events and so on. This requires a core algorithm for process scheduling. The algorithm is CFS (Completely Fair Scheduler). Summarize the CFS process scheduling in a single sentence in the LInux Kernel Development Book:
Run the process represented by the leftmost leaf node in the Rbtree tree.
In a tree node with a self-balancing binary search tree red-black tree Rbtree, the next data that should run the
1. Types of routine work scheduling
One is routine, that is, every certain period to be executed once;
One is sudden, that is, just do it once.
In order to achieve the above two functions, it is necessary to use the two commands of at and Crontab.
At:at is a command to finish scheduling only once, but to run at, you must have ATD support for this service, ATD may not start by default, then the AT command will fail.
Crontab:crontab the tasks configured by this comma

Today, I have thoroughly understood this method that once gave me a headache. I will focus on the following:
The first parameter is the TimerTask class. In the package: import java. util. TimerTask. the user must inherit the class and implement the public void run () method, because the TimerTask class implements

When it comes to scheduling scheduled tasks, it is believed that many people think of celery, or write a script that plugs into crontab. However, a small timing script, to use celery words too "heavy".So, I found a lightweight scheduled Task Scheduler library: schedule. Task Scheduler, a library of lightweight scheduled task scheduling: schedule. The installation of the library or the simplest pip install
The Alarm controller demonstrates how to use the Alarm event in an Android app, with features similar to Java.util.Timer, TimerTask. But alarm can do this even after the current application exits schedule a task is executed at the specified time.Alarmmanager is used to manage alarm events and supports single or recurring executions. As with the majority of Android services, Alarmmanager also obtains the service object through Getsystemservice:Alarmman

It is difficult to accurately estimate the construction period, which is the same as that of the product. I have seen some methods or tools that can solve these two problems,:

How Linux is scheduled in many processes, this involves the Linux process scheduling concept, the Linux kernel in the schedule () function to determine whether the process to switch, if you want to switch, switch to which process and so on.
The timing of Linux process scheduling is mainly as follows:
1, the process of state transition time: Process termination, process sleep;
2. The time slice of the current process is run out (current->counter=0);
3.
