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 or source, is a plain text computer program written in a programming language. A programmer writes the human readable source code to control the behavior of a computer. Since a computer, at base, only understands machine code, source code must be Translator (computing), translated before a computer can Execution (computing), execute it. The translation process can be implemented three ways. Source code can be converted into machine code by a compiler or an assembler (computing), assembler. The resulting executable is machine code ready for the computer. Alternatively, source code can be executed without conversion via an interpreter (computing), interpreter. An interpreter loads the source code into memory. It simultaneously translates and executes each statement (computer science), statement. A method that combines compilation and interpretation is to first produce bytecode. Bytecode is an intermediate representation of source code tha ...

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 UDB (formerly UndoDB), a reversible debugger for Linux Linux ( ) is a family of open source Unix-like operating systems based on the Linux kernel, an kernel (operating system), operating system kernel first released on September 17, 1991, by Linus Torvalds. Linux is typically package manager, pac ... 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. ...

Record And Replay Debugging
Record and replay debugging is the process of recording the execution of a software program so that it may be played back within a debugger to help diagnose and resolve defects. The concept is analogous to the use of a flight data recorder to diagnose the cause of an airplane flight malfunction. Recording and replaying Record and replay debuggers record application state at every step of the program's process and thread execution, including memory interactions, deterministic and non-deterministic inputs, system resource status, and store it to disk in a log. The recording allows the program to be replayed again and again, and debugged exactly as it happened. Usage Recordings can be made in one location and replayed in another, which makes it useful for remote debugging. Record and replay debugging is particularly useful for debugging intermittent and non-deterministic defects, which can be difficult to reproduce. Record and replay debugging technology is often fundamental to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Functional Programming Languages
This is a list of notable programming languages, grouped by type. The groupings are overlapping; not mutually exclusive. A language can be listed in multiple groupings. Agent-oriented programming languages Agent-oriented programming allows the developer to build, extend and use software agents, which are abstractions of objects that can message other agents. * Clojure * F# * GOAL * SARL Array languages Array programming (also termed ''vector'' or ''multidimensional'') languages generalize operations on scalars to apply transparently to vectors, matrices, and higher-dimensional arrays. * A+ * Ada * Analytica * APL * Chapel * Dartmouth BASIC * Fortran (As of Fortran 90) * FreeMat * GAUSS * Interactive Data Language (IDL) * J * Julia * K * MATLAB * Octave * Q * R * Raku * S * Scilab * S-Lang * SequenceL * Speakeasy * Wolfram Mathematica (Wolfram language) * X10 * ZPL Aspect-oriented programming languages Aspect-oriented programming enables d ...
