Illustration of the dining philosophers problem. Each philosopher has a bowl of spaghetti and can reach two of the forks. In computer science, the dining philosophers problem is an example problem often used in concurrent algorithm design to illustrate synchronization issues and techniques for resolving them.
This is a list of proprietary source-available software, which has available source code, but is not classified as free software or open-source software. In some cases, this type of software is originally sold and released without the source code , and the source code becomes available later.
Illumos, from the OpenSolaris kernel OS/Net, after Oracle closed down public access to the source code. webtrees , from PhpGedView , due to SourceForge 's policy on exporting encryption. Xonotic , from Nexuiz , after that project was taken proprietary.
David A. Wheeler notes [9] four possible outcomes of a fork, with examples: The death of the fork. This is by far the most common case. It is easy to declare a fork, but considerable effort to continue independent development and support. A re-merging of the fork (e.g., egcs becoming "blessed" as the new version of GNU Compiler Collection.)
Java code coverage tools are of two types: first, tools that add statements to the Java source code and require its recompilation. Second, tools that instrument the bytecode, either before or during execution. The goal is to find out which parts of the code are tested by registering the lines of code executed when running a test.
Implementations of the fork–join model will typically fork tasks, fibers or lightweight threads, not operating-system-level "heavyweight" threads or processes, and use a thread pool to execute these tasks: the fork primitive allows the programmer to specify potential parallelism, which the implementation then maps onto actual parallel execution.

In October 2016, the lead developers of Activiti (software) left Alfresco (software) and started the Flowable Open Source project based on a fork of Activiti code. [6] [7]The first version of Flowable was 5.22, based on a fork of Activiti 5.21, but added Transient Variables. [8]
