A program called cron may be used to schedule these tasks. With cron, tasks are commonly scheduled to be executed when the system is expected to be idle. If the system is off at the moment a task should be run, it will not be executed. Anacron is different and moves tasks to different moments so they are run when the system is on and utilising ...
Much detail is omitted here concerning the inaccuracies of computer time-of-day tracking, Unix alarm scheduling, explicit time-of-day changes, and process management, all of which account for the majority of the lines of code in this cron. This cron also captured the output of stdout and stderr and e-mailed any output to the crontab owner.
Each task corresponds to single action. On Windows 95 (with Internet Explorer 4.0 or later), Windows 98 and Windows Me, the Task Scheduler runs as an ordinary program, mstask.exe. It also displays a status icon in the notification area on Windows 95 and Windows 98 and runs as a hidden service on Windows Me, but can be made to show a tray icon. [1]
Conceptually, it repeatedly selects a source of the dependency graph, appends it to the current instruction schedule and removes it from the graph. This may cause other vertices to be sources, which will then also be considered for scheduling. The algorithm terminates if the graph is empty. To arrive at a good schedule, stalls should be prevented.
Apache Velocity first released in April 2001, is a Java-based template engine that provides a template language to reference objects defined in Java code. It aims to ensure clean separation between the presentation tier and business tiers in a Web application (the model–view–controller design pattern).
In a general job scheduling problem, we are given n jobs J 1, J 2, ..., J n of varying processing times, which need to be scheduled on m machines with varying processing power, while trying to minimize the makespan – the total length of the schedule (that is, when all the jobs have finished processing).

The Bean Scripting Framework is a method of allowing the use of scripting in Java code. It provides a set of Java classes which provides support within Java applications for scripting languages, and also allows access to Java objects and methods. Some examples of languages that can be used in combination with BSF and Java include Python, Jython ...
