Several Java programming language misusage might conduct a program to generate incorrect results despite being compiled correctly. This topic main purpose is to list common pitfalls with their causes, and to propose the correct way to avoid falling in such problems. This topic is about specifi...

Covariance of a parameter or a return value for a virtual member function m is where its type T gets more specific in a derived class' override of m. The type T then varies (variance) in specificity in the same way (co) as the classes providing m. C++ provides language support for covariant return...

This section provides an overview of what linux-device-driver is, and why a developer might want to use it. It should also mention any large subjects within linux-device-driver, and link out to the related topics. Since the Documentation for linux-device-driver is new, you may need to create ini...

This section provides an overview of what recyclerview is, and why a developer might want to use it. It should also mention any large subjects within recyclerview, and link out to the related topics. Since the Documentation for recyclerview is new, you may need to create initial versions of thos...

ServiceLoader can be used to get instances of classes extending a given type(=service) that are specified in a file packed in a .jar file. The service that is extended/implemented is often a interface, but this is not required. The extending/implementing classes need to provide a zero argument co...

This topic describes a number of "pitfalls" (i.e. mistakes that novice java programmers make) that relate to Java application performance. This topic describes some "micro" Java coding practices that are inefficient. In most cases, the inefficiencies are relatively small, ...

In Bash 4.2, a shell built-in time conversion for printf was introduced: the format specification %(datefmt)T makes printf output the date-time string corresponding to the format string datefmt as understood by strftime. printf '%(dateFmt)T' # dateFmt can be any format string that strftime rec...

In this topic we propose a simple method to correctly design simple digital circuits with VHDL. The method is based on graphical block diagrams and an easy-to-remember principle: Think hardware first, code VHDL next It is intended for beginners in digital hardware design using VHDL, with a limited...
