Tim Peters (software Engineer)
Tim Peters is an American software developer who is known for creating the Timsort hybrid sorting algorithm and for his major contributions to the Python programming language and its original CPython implementation. A pre-1.0 CPython user, he was among the group of early adopters who contributed to the detailed design of the language in its early stages. He later created the Timsort algorithm (based on earlier work on the use of "galloping" search) which has been used in Python since version 2.3, as well as in other widely used computing platforms, including the V8 JavaScript engine powering the Google Chrome and Chromium web browsers, as well as Node.js. He has also contributed the doctest and timeit modules to the Python standard library. Peters also wrote the Zen of Python, intended as a statement of Python's design philosophy, which was incorporated into the official Python literature as Python Enhancement Proposal 20 and in the Python interpreter as an easter egg.

Easter Egg (media)
File:Carl Oswald Rostosky - Zwei Kaninchen und ein Igel 1861.jpg, 250px, An image that reveals an Easter egg when the hedgehog is clicked or tapped. Another Easter egg can be found in a tooltip when a mouse pointer is hovered over the hedgehog. rect 455 383 550 434 I am a hedgehog, NOT an egg! desc none An Easter egg is a message, image, or feature hidden in software, a video game, a film, or another, usually electronic, medium. The term used in this manner was coined around 1979 by Steve Wright, the then-Director of Software Development in the Atari Consumer Division, to describe a hidden message in the Atari video game ''Adventure'', in reference to an Easter egg hunt. The earliest known video game Easter egg is in '' Moonlander'' (1973), in which the player tries to land a Lunar module on the moon; if the player opts to fly the module horizontally through several of the game's screens, they encounter a McDonald's restaurant, and if they land next to it the astronaut will ...

Computer Programmers
A computer programmer, sometimes referred to as a software developer, a software engineer, a programmer or a coder, is a person who creates computer programs — often for larger computer software. A programmer is someone who writes/creates computer software or applications by providing a specific programming language to the computer. Most programmers have extensive computing and coding experience in many varieties of programming languages and platforms, such as Structured Query Language (SQL), Perl, Extensible Markup Language (XML), PHP, HTML, C, C++ and Java. A programmer's most often-used computer language (e.g., Assembly, C, C++, C#, JavaScript, Lisp, Python, Java, etc.) may be prefixed to the aforementioned terms. Some who work with web programming languages may also prefix their titles with ''web''. Terminology There is no industry-wide standard terminology, so "programmer" and "software engineer" might refer to the same role at different companies. Most typically, ...

History Of Python
The programming language Python was conceived in the late 1980s, and its implementation was started in December 1989 by Guido van Rossum at CWI in the Netherlands as a successor to ABC capable of exception handling and interfacing with the Amoeba operating system. Van Rossum is Python's principal author, and his continuing central role in deciding the direction of Python is reflected in the title given to him by the Python community, ''Benevolent Dictator for Life'' (BDFL). (However, van Rossum stepped down as leader on July 12, 2018.). Python was named after the BBC TV show '' Monty Python's Flying Circus''. Python 2.0 was released on October 16, 2000, with many major new features, including a cycle-detecting garbage collector (in addition to reference counting) for memory management and support for Unicode. However, the most important change was to the development process itself, with a shift to a more transparent and community-backed process. Python 3.0, a major, backw ...

Netlib
Netlib is a repository of software for scientific computing maintained by AT&T, Bell Laboratories, the University of Tennessee and Oak Ridge National Laboratory. Netlib comprises many separate programs and libraries. Most of the code is written in C and Fortran, with some programs in other languages. History The project began with email distribution on UUCP, ARPANET and CSNET in the 1980s. The code base of Netlib was written at a time when computer software was not yet considered merchandise. Therefore, no license terms or terms of use are stated for many programs. Before the Berne Convention Implementation Act of 1988 (and the earlier Copyright Act of 1976) works without an explicit copyright notice were public-domain software. Also, most of the Netlib code is work of US government employees and therefore in the public domain. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Kendall Square Research
Kendall Square Research (KSR) was a supercomputer company headquartered originally in Kendall Square in Cambridge, Massachusetts in 1986, near Massachusetts Institute of Technology (MIT). It was co-founded by Steven Frank and Henry Burkhardt III, who had formerly helped found Data General and Encore Computer and was one of the original team that designed the PDP-8. KSR produced two models of supercomputer, the KSR1 and KSR2. It went bankrupt in 1994. Technology The KSR systems ran a specially customized version of the OSF/1 operating system, a Unix variant, with programs compiled by a KSR-specific port of the Green Hills Software C and FORTRAN compilers. The architecture was shared memory implemented as a cache-only memory architecture or "COMA". Being all cache, memory dynamically migrated and replicated in a coherent manner based on the access pattern of individual processors. The processors were arranged in a hierarchy of rings, and the operating system mediated process mig ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stack Overflow
In software, a stack overflow occurs if the call stack pointer exceeds the stack bound. The call stack may consist of a limited amount of address space, often determined at the start of the program. The size of the call stack depends on many factors, including the programming language, machine architecture, multi-threading, and amount of available memory. When a program attempts to use more space than is available on the call stack (that is, when it attempts to access memory beyond the call stack's bounds, which is essentially a buffer overflow), the stack is said to ''overflow'', typically resulting in a program crash. Causes Infinite recursion The most-common cause of stack overflow is excessively deep or infinite recursion, in which a function calls itself so many times that the space needed to store the variables and information associated with each call is more than can fit on the stack.
