Time Travel Debugging
Time travel debugging or time traveling debugging is the process of stepping back in time through source code to understand what is happening during execution of a computer program. Typically, debugging and debuggers, tools that assist a user with the process of debugging, allow users to pause the execution of running software and inspect the current state of the program. Users can then step forward in time, stepping into or over statements and proceeding in a forward direction. Interactive debuggers include the ability to modify code and step forward based on updated information. Reverse debugging tools allow users to step backwards in time through the steps that resulted in reaching a particular point in the program. Time traveling debuggers provide these features and also allow users to interact with the program, changing the history if desired, and watch how the program responds. Characteristics supporting bi-directional travel There are several characteristics that support t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Source Code
In computing, source code, or simply code, is any collection of code, with or without comments, written using a human-readable programming language, usually as plain text. The source code of a program is specially designed to facilitate the work of computer programmers, who specify the actions to be performed by a computer mostly by writing source code. The source code is often transformed by an assembler or compiler into binary machine code that can be executed by the computer. The machine code is then available for execution at a later time. Most application software is distributed in a form that includes only executable files. If the source code were included it would be useful to a user, programmer or a system administrator, any of whom might wish to study or modify the program. Alternatively, depending on the technology being used, source code may be interpreted and executed directly. Definitions Richard Stallman's definition, formulated in his 1989 seminal li ...

Undo (company)
Undo is a software debugging company based in Cambridge, UK. The company was founded in 2005 by Greg Law and Julian Smith. Undo’s technology is used by software engineering teams to debug software programs. History Undo was initially bootstrapped in 2005 by Greg Law and Julian Smith out of Law’s garden shed in Cambridge. Law and Smith developed the core technology that would eventually become UndoDB, a reversible debugger for Linux Linux ( or ) is a family of open-source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991, by Linus Torvalds. Linux is typically packaged as a Linux distribution, w ... software. LiveRecorder was then developed based on UndoDB to enable development teams to record and replay the execution of software programs. In 2012, Undo secured its initial seed funding. It closed a $3.3 million Series A funding round in 2016, and a $14 million Series B in 2018. References {{re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Debuggers
A debugger or debugging tool is a computer program used to test and debug other programs (the "target" program). The main use of a debugger is to run the target program under controlled conditions that permit the programmer to track its execution and monitor changes in computer resources that may indicate malfunctioning code. Typical debugging facilities include the ability to run or halt the target program at specific points, display the contents of memory, CPU registers or storage devices (such as disk drives), and modify memory or register contents in order to enter selected test data that might be a cause of faulty program execution. The code to be examined might alternatively be running on an ''instruction set simulator'' (ISS), a technique that allows great power in its ability to halt when specific conditions are encountered, but which will typically be somewhat slower than executing the code directly on the appropriate (or the same) processor. Some debuggers offer two m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Functional Programming Languages
This is a list of notable programming languages, grouped by type. There is no overarching classification scheme for programming languages. Thus, in many cases, a language is listed under multiple headings (in this regard, see "#Multiparadigm languages, Multiparadigm languages" below). Array languages Array programming (also termed ''vector'' or ''multidimensional'') languages generalize operations on scalars to apply transparently to Vector (mathematics), vectors, Matrix (mathematics), matrices, and higher-dimensional arrays. * A+ (programming language), A+ * Analytica (software), Analytica * APL (programming language), APL * BQN (programming language), BQN * Chapel (programming language), Chapel * Fortran 90 * FreeMat * GAUSS (software), GAUSS * Interactive Data Language (IDL) * J (programming language), J * Julia (programming language), Julia * K (programming language), K * MATLAB * GNU Octave, Octave * Q (programming language from Kx Systems), Q * R (programming la ...
