Computer Scientist
A computer scientist is a person who is trained in the academic study of computer science. Computer scientists typically work on the theoretical side of computation, as opposed to the hardware side on which computer engineers mainly focus (although there is overlap). Although computer scientists can also focus their work and research on specific areas (such as algorithm and data structure development and design, software engineering, information theory, database theory, computational complexity theory, numerical analysis, programming language theory, computer graphics, and computer vision), their foundation is the theoretical study of computing from which these other fields derive. A primary goal of computer scientists is to develop or validate models, often mathematical, to describe the properties of computational systems (processors, programs, computers interacting with people, computers interacting with other computers, etc.) with an overall objective of discovering d ...

Software Testing
Software testing is the act of examining the artifacts and the behavior of the software under test by validation and verification. Software testing can also provide an objective, independent view of the software to allow the business to appreciate and understand the risks of software implementation. Test techniques include, but not necessarily limited to: * analyzing the product requirements for completeness and correctness in various contexts like industry perspective, business perspective, feasibility and viability of implementation, usability, performance, security, infrastructure considerations, etc. * reviewing the product architecture and the overall design of the product * working with product developers on improvement in coding techniques, design patterns, tests that can be written as part of code based on various techniques like boundary conditions, etc. * executing a program or application with the intent of examining behavior * reviewing the deployment infrastructure a ...

Software Bug
A software bug is an error, flaw or fault in the design, development, or operation of computer software that causes it to produce an incorrect or unexpected result, or to behave in unintended ways. The process of finding and correcting bugs is termed "debugging" and often uses formal techniques or tools to pinpoint bugs. Since the 1950s, some computer systems have been designed to deter, detect or auto-correct various computer bugs during operations. Bugs in software can arise from mistakes and errors made in interpreting and extracting users' requirements, planning a program's design, writing its source code, and from interaction with humans, hardware and programs, such as operating systems or libraries. A program with many, or serious, bugs is often described as ''buggy''. Bugs can trigger errors that may have ripple effects. The effects of bugs may be subtle, such as unintended text formatting, through to more obvious effects such as causing a program to crash, freezing th ...

Program Proving
In the context of hardware and software systems, formal verification is the act of proving or disproving the correctness of intended algorithms underlying a system with respect to a certain formal specification or property, using formal methods of mathematics. Formal verification can be helpful in proving the correctness of systems such as: cryptographic protocols, combinational circuits, digital circuits with internal memory, and software expressed as source code. The verification of these systems is done by providing a formal proof on an abstract mathematical model of the system, the correspondence between the mathematical model and the nature of the system being otherwise known by construction. Examples of mathematical objects often used to model systems are: finite-state machines, labelled transition systems, Petri nets, vector addition systems, timed automata, hybrid automata, process algebra, formal semantics of programming languages such as operational semantics ...

Compiler
In computing, a compiler is a computer program that translates computer code written in one programming language (the ''source'' language) into another language (the ''target'' language). The name "compiler" is primarily used for programs that translate source code from a high-level programming language to a low-level programming language (e.g. assembly language, object code, or machine code) to create an executable program. Compilers: Principles, Techniques, and Tools by Alfred V. Aho, Ravi Sethi, Jeffrey D. Ullman - Second Edition, 2007 There are many different types of compilers which produce output in different useful forms. A ''cross-compiler'' produces code for a different CPU or operating system than the one on which the cross-compiler itself runs. A ''bootstrap compiler'' is often a temporary compiler, used for compiling a more permanent or better optimised compiler for a language. Related software include, a program that translates from a low-level language t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Unix
Unix (; trademarked as UNIX) is a family of multitasking, multiuser computer operating systems that derive from the original AT&T Unix, whose development started in 1969 at the Bell Labs research center by Ken Thompson, Dennis Ritchie, and others. Initially intended for use inside the Bell System, AT&T licensed Unix to outside parties in the late 1970s, leading to a variety of both academic and commercial Unix variants from vendors including University of California, Berkeley ( BSD), Microsoft ( Xenix), Sun Microsystems ( SunOS/ Solaris), HP/ HPE ( HP-UX), and IBM ( AIX). In the early 1990s, AT&T sold its rights in Unix to Novell, which then sold the UNIX trademark to The Open Group, an industry consortium founded in 1996. The Open Group allows the use of the mark for certified operating systems that comply with the Single UNIX Specification (SUS). Unix systems are characterized by a modular design that is sometimes called the " Unix philosophy". According to thi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hack (technology Slang)
A hacker is a person skilled in information technology who uses their technical knowledge to achieve a goal or overcome an obstacle, within a computerized system by non-standard means. Though the term ''hacker'' has become associated in popular culture with a ''security hacker''someone who utilizes their technical know-how of bugs or exploits to break into computer systems and access data which would otherwise be inaccessible to them – hacking can also be utilized by legitimate figures in legal situations. For example, law enforcement agencies sometimes use hacking techniques in order to collect evidence on criminals and other malicious actors. This could include using anonymity tools (such as a VPN, or the dark web) to mask their identities online, posing as criminals themselves. Likewise, covert world agencies can employ hacking techniques in the legal conduct of their work. On the other hand, hacking and cyber-attacks are used extra- and illegally by law enforcement ...

The Song Of Hiawatha
''The Song of Hiawatha'' is an 1855 epic poem in trochaic tetrameter by Henry Wadsworth Longfellow which features Native American characters. The epic relates the fictional adventures of an Ojibwe warrior named Hiawatha and the tragedy of his love for Minnehaha, a Dakota woman. Events in the story are set in the Pictured Rocks area of Michigan on the south shore of Lake Superior. Longfellow's poem is based on oral traditions surrounding the figure of Manabozho, but it also contains his own innovations. Longfellow drew some of his material from his friendship with Ojibwe Chief '' Kahge-ga-gah-bowh'', who would visit at Longfellow's home. He also had frequent encounters with Black Hawk and other Sauk people on Boston Common, and he drew from ''Algic Researches'' (1839) and other writings by Henry Rowe Schoolcraft, an ethnographer and United States Indian agent, and from ''Heckewelder's Narratives''. In sentiment, scope, overall conception, and many particulars, Longfellow in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Henry Wadsworth Longfellow
Henry Wadsworth Longfellow (February 27, 1807 – March 24, 1882) was an American poet and educator. His original works include " Paul Revere's Ride", '' The Song of Hiawatha'', and ''Evangeline''. He was the first American to completely translate Dante Alighieri's ''Divine Comedy'' and was one of the fireside poets from New England. Longfellow was born in Portland, Maine, which was then still part of Massachusetts. He graduated from Bowdoin College and became a professor there and, later, at Harvard College after studying in Europe. His first major poetry collections were ''Voices of the Night'' (1839) and ''Ballads and Other Poems'' (1841). He retired from teaching in 1854 to focus on his writing, and he lived the remainder of his life in the Revolutionary War headquarters of George Washington in Cambridge, Massachusetts. His first wife, Mary Potter, died in 1835 after a miscarriage. His second wife, Frances Appleton, died in 1861 after sustaining burns when her dress cau ...

Parody
A parody, also known as a spoof, a satire, a send-up, a take-off, a lampoon, a play on (something), or a caricature, is a creative work designed to imitate, comment on, and/or mock its subject by means of satiric or ironic imitation. Often its subject is an original work or some aspect of it (theme/content, author, style, etc), but a parody can also be about a real-life person (e.g. a politician), event, or movement (e.g. the French Revolution or 1960s counterculture). Literary scholar Professor Simon Dentith defines parody as "any cultural practice which provides a relatively polemical allusive imitation of another cultural production or practice". The literary theorist Linda Hutcheon said "parody ... is imitation, not always at the expense of the parodied text." Parody may be found in art or culture, including literature, music, theater, television and film, animation, and gaming. Some parody is practiced in theater. The writer and critic John Gross observes in his ''Oxfor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
