By June 2015, its ranking had dropped to below 50th in the index, placing it lower than COBOL and Fortran. 2001: Dahl, Nygaard | is available,[79]:151–152 idiomatic concurrent programs instead prefer channels, which provide send messages between goroutines. 2004: Cerf, Kahn | Go is influenced by C, but with an emphasis on greater simplicity and safety. Each major Go release is supported until there are two newer major releases.[39]. Follow edited Jul 24 '18 at 15:37. where "fmt" is the package for formatted I/O, similar to C's C file input/output. Letzte Überprüfung: 30. benutzte. Go is a general-purpose programming language with advanced features and a clean syntax. Thus two structs that differ only in their tags may be converted from one to the other. The definition of type T need not (and cannot) identify type I. 1981: Codd | Loosened return requirements rules. On September 25, 2007, after Rob Pike, Robert Griesemer, and KenThompson had been discussing a new programming language for a fewdays, Rob suggested the name “Go.” The next year, Ian Lance Taylor and I joined the team, and togetherthe five of us built two compilers and a standard library, leading upto the open-source releaseon November 10, 2009. [81], The existence of channels sets Go apart from actor model-style concurrent languages like Erlang, where messages are addressed directly to actors (corresponding to goroutines). Concurrency refers not only to CPU parallelism, but also to asynchrony: letting slow operations like a database or network read run while the program does other work, as is common in event-based servers. Go is a statically typed, compiled programming language designed at Google[14] by Robert Griesemer, Rob Pike, and Ken Thompson. [52], For each type T and each non-negative integer constant n, there is an array type denoted [n]T; arrays of differing lengths are thus of different types. Kenneth is related to Marilyn B Thompson and Carrie A Thompson as well as 2 additional people. An ecosystem of third-party tools adds to the standard distribution, such as gocode, which enables code autocompletion in many text editors, goimports, which automatically adds/removes package imports as needed, and errcheck, which detects code that might unintentionally ignore errors. Various studies have been done into the effectiveness of this approach. Thompson verließ die Bell Labs am 1. [73], In Go's package system, each package has a path (e.g., "compress/bzip2" or "golang.org/x/net/html") and a name (e.g., bzip2 or html). Als Anekdote wird gerne erzählt, dass die wahre Motivation hinter der Entwicklung von Unix war, das Spiel Space Travel auf eine wenig verwendete PDP-7 zu portieren,[2] da auf den normalen Großrechnern eine Stunde Rechenzeit 75 US-Dollar kostete. The team decided to create Go because they were frustrated with C++ and Java, which through the years have become cumbersome and clumsy to work with. Aside from its support for interfaces, Go's type system is nominal: the type keyword can be used to define a new named type, which is distinct from other named types that have the same layout (in the case of a struct, the same members in the same order). Februar 1943 in New Orleans, Louisiana in den Vereinigten Staaten geboren und feierte 2021 seinen 78. . Is there a "creat" command? [100], Initially omitted, the exception-like panic/recover mechanism was eventually added, which the Go authors advise using for unrecoverable errors such as those that should halt an entire program or server request, or as a shortcut to propagate errors up the stack within a package (but not across package boundaries; there, error returns are the standard API).[101][102][103][104]. [92][93], Go deliberately omits certain features common in other languages, including (implementation) inheritance, generic programming, assertions,[e] pointer arithmetic,[d] implicit type conversions, untagged unions,[f] and tagged unions. [72] Like some other types implemented using pointers in Go, interface values are nil if uninitialized. 2013: Lamport | Ian Lance Taylor, who had improved the Go code for Hundt's paper, had not been aware of the intention to publish his code, and says that his version was "never intended to be an example of idiomatic or efficient Go"; Russ Cox then optimized the Go code, as well as the C++ code, and got the Go code to run slightly faster than C++ and more than an order of magnitude faster than the code in the paper. Ken Thomson became Director-General for Constitution and External Affairs in July 2017. [32][33], In April 2018, the original logo was replaced with a stylized GO slanting right with trailing streamlines. [22] The designers wanted to address criticism of other languages in use at Google, but keep their useful characteristics:[23], The designers were primarily motivated by their shared dislike of C++.[25][26][27]. Improve this question . The garbage collector has been re-engineered for 1.5. [97] They are also open to standardizing ways to apply code generation. 2014: Stonebraker | 1989: Kahan | Go 1.3 has changed the implementation of goroutine stacks away from the old, "segmented" model to a contiguous model. The compiler and runtime are now implemented in Go and assembler, without C. Now that the Go compiler and runtime are implemented in Go, a Go compiler must be available to compile the distribution from source. Go has a memory model describing how goroutines must use channels or other operations to safely share data. For a while now, the garbage collector has been. Preisvergleich von Hardware und Software sowie Downloads bei Heise Medien. Lack of support for generic programming and the verbosity of error handling in Go 1.x had drawn considerable criticism. [113] Target function example: Test code (note that assert keyword is missing in Go; tests live in
_test.go at the same package): The net/http package provides support for creating web applications. 1985: Karp | Go was designed at Google in 2007 to improve programming productivity in an era of multicore, networked machines and large codebases. [85], Concurrency-related structural conventions of Go (channels and alternative channel inputs) are derived from Tony Hoare's communicating sequential processes model. He has held positions as General Manager, Resident Manager, Corporate Training Manager and Rooms Division Director. Some notable open-source applications written in Go include:[114]. [112], The following simple program demonstrates Go's concurrency features to implement an asynchronous program. [96], Of the omitted language features, the designers explicitly argue against assertions and pointer arithmetic, while defending the choice to omit type inheritance as giving a more useful language, encouraging instead the use of interfaces to achieve dynamic dispatch[h] and composition to reuse code.

Semicolons still terminate statements,[a] but are implicit when the end of a line occurs. ), booleans, and character strings (string). 1984: Wirth | A third-party transpiler GopherJS[21] compiles Go to JavaScript for front-end web development. A 2011 evaluation of the language and its gc implementation in comparison to C++ (GCC), Java and Scala by a Google engineer found: Go offers interesting language features, which also allow for a concise and standardized notation. The Go 1.3 memory model adds a new rule concerning sending and receiving on buffered channels, to make explicit that a buffered channel can be used as a simple semaphore, using a send into the channel to acquire and a receive from the channel to release. // ZeroBroadcast reports whether addr is 255.255.255.255. He is married to Lorna and is the father of Rachel, Dylan and, from Series 3 on wards, Sid, throughout the series Ken is forced to put up with Cuckoo's incredibly annoying behaviour to a certainly high degree. 2009: Thacker | Go 1.11.3 and later fix the TLS authentication vulnerability in the crypto/x509 package. Simply assigning x to a variable of type ipv4addr is a type error. 1971: McCarthy | [76], Proposals exist to introduce a proper package management solution for Go similar to CPAN for Perl or Rust's cargo system or Node's npm system. All versions up to the current Go 1.15 release[38] have maintained this promise. Hence with the help of Ken Thompson, Rob Pike, and Robert Griesemer, they created a language Go that could give developers the experience of … [56] There is no pointer arithmetic,[d] except via the special unsafe.Pointer type in the standard library. asked Nov 11 '09 at 6:38. when localhost:8080 is visited. ", Language FAQ "Why does Go not have assertions? We'll help you find the loan that ideally fits your individual or company needs. Terminally ill Shamus Rafferty, who was Ken's History lecturer at university, tells Ken that he wanted to buy it, so Ken reluctantly lends it to him. Unix user name: ken; Unix uid: 6; Operating systems created: Unix, Plan 9 from Bell Labs. The matter has to do with a Real Estate Appraisal fraud and investment that is being done by Ken Thompson, President and a Real Estate Broker of Mincom Realty system Inc. 755165 Ontario Inc. with its Head Office based in … However, the Gopher mascot remained the same.[34]. ", without specifying the types of variables used. Go is still experimental and still a little rough around the edges. Questions "How do I get dynamic dispatch of methods?" 1998: Gray | 14:00 PM Ken Thompson Go forth, make astute purchases and fill your wardrobe with beautiful things. This recursively describes data in the form of a dictionary with string keys and values of any type. I thought it would be useful to essentially anybody like me because it was not built for someone else or some third party. The overhead of deferred function calls has been reduced by about half. 1999: Brooks | Kenneth Lane Thompson. Dynamic arrays are available as "slices", denoted []T for some type T. These have a length and a capacity specifying when new memory needs to be allocated to expand the array. Er entwickelte die Programmiersprache B, einen Vorgänger der Sprache C, die noch heute zu den weltweit meistbenutzten Programmiersprachen gehört. Zusammen mit Dennis Ritchie erhielt er 1983 den Turing Award, 1990 die Richard-W.-Hamming-Medaille des Institute of Electrical and Electronics Engineers (IEEE). 2019: Catmull, Hanrahan. Go 1.11 adds preliminary support for a new concept called “modules”, an alternative to GOPATH with integrated support for versioning and package distribution. For your financing needs, Thompson Group Classic Chevrolet Fleet & Commercial works with many local and national banks. Februar 1943 in New Orleans, Louisiana) ist ein US-amerikanischer Informatiker, der unter anderem maßgeblich an der Entwicklung des Unix-Betriebssystems beteiligt war. Improved modules support (in preparation for being the default in Go 1.13), Improved macOS & iOS forwards compatibility, support for TLS 1.3 in the crypto/tls package by default (opt-out will be removed in Go 1.14), A syntax and environment adopting patterns more common in, Optional concise variable declaration and initialization through. A slicing operation creates a new slice by describing a contiguous section of an already-created array or slice. … We considered [them but] they overlap in confusing ways with interfaces…. In seiner Rede zum Erhalt des Turing Awards beschrieb Thompson, wie er eine besondere Art von Backdoor entwickelte. Interfaces can embed other interfaces with the effect of creating a combined interface that is satisfied by exactly the types that implement the embedded interface and any methods that the newly defined interface adds. Danach war er bis 2006 Partner bei Entrisphere, Inc. und arbeitet inzwischen als angesehener Entwickler bei Google, wo er zusammen mit Rob Pike und Robert Griesemer die Programmiersprache Go entwickelte. Papers. 1980: Hoare | Ferner entwickelte er 1992 zusammen mit Rob Pike UTF-8, ein weit verbreitetes System zum Kodieren von Unicode-Zeichen.[5]. 2015: Diffie, Hellman | [89], There are no restrictions on how goroutines access shared data, making race conditions possible. Iterations over small maps no longer happen in a consistent order. [This is the text ofmy talk todayat Gophercon 2017, asking for the entire Go community'shelp as we discuss and plan Go 2.] Languages created: B, Go. Institute of Electrical and Electronics Engineers, https://de.wikipedia.org/w/index.php?title=Ken_Thompson&oldid=206060369, Mitglied der National Academy of Sciences, Mitglied der American Academy of Arts and Sciences, „Creative Commons Attribution/Share Alike“, Thompson, Kenneth Lane (vollständiger Name). [87] While the communicating-processes model is favored in Go, it is not the only one: all goroutines in a program share a single address space. In the 11 months since our release, there has been minimal confusion of the two languages. 1996: Pnueli | Élete. Due to an oversight, the rule that allowed the element type to be elided from slice literals was not applied to map keys. 4. 1990: Corbató | Ken Thomson (* 12. All the hoops that the C++ programmer had to jump through in order to use a C-compatible language make no sense anymore -- they're just a waste of time and effort. Strings are immutable; built-in operators and keywords (rather than functions) provide concatenation, comparison, and UTF-8 encoding/decoding. The complexity of C++ (even more complexity has been added in the new C++), and the resulting impact on productivity, is no longer justified. Die Ergebnisse dieser Arbeit stellte er auf vier Endspiel-CDs anderen zum Selbstkostenpreis zur Verfügung. Responsibilities The Director General for Constitution and External Affairs is focused on leading and supporting work across the Scottish Government on intergovernmental relations, EU exit, constitutional issues, and supporting Cabinet decision-making. Ken Thompson, joined Dimension Development in 1991 following a ten year career with Stouffer Hotels & Resorts and Doubletree Hotels. [b] Methods may return multiple values, and returning a result, err pair is the conventional way a method indicates an error to its caller in Go. in the language FAQ. Dezember 2000. [65][66] Although the term duck typing is not precisely defined and therefore not wrong, it usually implies that type conformance is not statically checked. There are a minimal number of fundamental language concepts and the syntax is clean and designed to be clear and unambiguous. [citation needed]. The parameter and return values determine a function type; thus, func(string, int32) (int, error) is the type of functions that take a string and a 32-bit signed integer, and return a signed integer (of default width) and a value of the built-in interface type error. 1988: Sutherland | Für Unix schrieb Thompson unter anderem die erste Shell, retronym Thompson-Shell „sh“, und den Zeileneditor ed. He's most famous for his work on Unix, but he's also quite well known for Plan 9, and for Multics, and for B, and for Belle, and for ed, and so on and so on. 1969: Minsky | For the Android search app by Google, "Google Go", for low-end Lollipop+ devices, see, This article incorporates material from the. The actor style can be simulated in Go by maintaining a one-to-one correspondence between goroutines and channels, but the language allows multiple goroutines to share a channel or a single goroutine to send and receive on multiple channels. File semantics in Go standard library are heavily based on POSIX semantics, and they do not map well to the, This page was last edited on 11 February 2021, at 14:20. The assembler also no longer implements MOVL $0, AX as an XORL instruction, to avoid clearing the condition flags unexpectedly. [59], Function types are indicated by the func keyword; they take zero or more parameters and return zero or more values, all of which are typed. Kenan Thompson, Actor: Saturday Night Live. "[151], "Google Go" redirects here. Some conversions between types (e.g., between the various integer types) are pre-defined and adding a new type may define additional conversions, but conversions between named types must always be invoked explicitly. 1973: Bachman | [citation needed], Constant expressions may be either typed or "untyped"; they are given a type when assigned to a typed variable if the value they represent passes a compile-time check. DDJ:You've received a lot of awards over the years for UNIX. 2010: Valiant | [79]:147, From these tools one can build concurrent constructs like worker pools, pipelines (in which, say, a file is decompressed and parsed as it downloads), background calls with timeout, "fan-out" parallel calls to a set of services, and others. 2019 wurden beide in die National Inventors Hall of Fame aufgenommen. [77], The Go language has built-in facilities, as well as library support, for writing concurrent programs. For the x86 64-bit port, the assembler now supports 359 new instructions, including the full AVX, AVX2, BMI, BMI2, F16C, FMA3, SSE2, SSE3, SSSE3, SSE4.1, and SSE4.2 extension sets. 2000: Yao | Addition of a race detector to the standard tool set. Wenn der Compiler selbst auf diesem System kompiliert wird, erkennt er dies und fügt den Schadcode wieder ein. [63]:282–283, Besides calling methods via interfaces, Go allows converting interface values to other types with a run-time type check. Kenneth „Ken“ Lane Thompson (* 4. history Share. 2008: Liskov | Dabei handelte es sich um einen Compiler, der bei der Kompilierung eines Unix-Login-Programms unbemerkt eine Hintertür einbaut. Go 1.2 introduces a configurable limit (default 10,000) to the total number of threads a single program may have. [53] The Google team built at least one compiler for an experimental Go dialect with generics, but did not release it. The best result we found for your search is Kenneth W Thompson Sr age 70s in Mesa, AZ in the Knoell East neighborhood. Kusalananda ♦ 225k 27 27 gold badges 427 427 silver badges 680 680 bronze badges. On October 12, 2010, the issue was closed by Google developer Russ Cox (@rsc) with the custom status "Unfortunate" accompanied by the following comment: "There are many computing products and services named Go. [12] Go is syntactically similar to C, but with memory safety, garbage collection, structural typing,[6] and CSP-style concurrency. I would like to submit a personal story to your Rip-off Report. Specifically, unless a program explicitly synchronizes via channels or other means, writes from one goroutine might be partly, entirely, or not at all visible to another, often with no guarantees about ordering of writes. Go 1.2 adds the ability to specify the capacity as well as the length when using a slicing operation on an existing array or slice. Kenneth Thompson is an orator and a Thought Leader on finance and economic matters. Ken Thompson is an American computer science pioneer and the principal inventor of the 'UNIX' operating system. Thomson studierte an der Columbia University Geschichte und Musiktheorie. [62]:255, The second are its interfaces, which provides runtime polymorphism. Wenn es einmalig gelingt, den präparierten Compiler auf einem System zu installieren, kann man die Backdoor-Codesequenz aus dem Quellcode des Compilers entfernen. The language specification does not specify how goroutines should be implemented, but current implementations multiplex a Go process's goroutines onto a smaller set of operating-system threads, similar to the scheduling performed in Erlang. 1979: Iverson | He discusses, too, whether our fears could be getting in the way of conserving biodiversity, and responding to the threat of climate change. Er erhielt für seine Arbeiten zahlreiche Ehrungen und Auszeichnungen, darunter den Turing Award. 2016: Berners-Lee | Several slices may share their underlying memory. Both Go and Go Mono adhere to the DIN 1450 standard by having a slashed zero, lowercase l with a tail, and an uppercase I with serifs. [63]:266 Interfaces are a class of types and provide a limited form of structural typing in the otherwise nominal type system of Go. He has been married to Christina Evangeline since November 11, 2011. Any object of type T for which functions exist matching all the required methods of interface type I is an object of type I as well. In November 2016, the Go and Go Mono fonts were released by type designers Charles Bigelow and Kris Holmes specifically for use by the Go project. Greg Davies, Actor: The Inbetweeners Movie. Timk Timk. See the document on eliminating stop-the-world stack re-scanning for details. | Kein GND-Personendatensatz. [29][30] Go is widely used in production at Google[31] and in many other organizations and open-source projects. The Go parser is now hand-written instead of generated. )", "Google's Go Wins Programming Language Of The Year Award", "TIOBE Programming Community Index for June 2015", "Google Go strikes back with C++ bake-off", "Google didn't google "Go" before naming their programming language, "Google 'Go' Name Brings Accusations Of Evil, "Issue 9 - go — I have already used the name for *MY* programming language", "Why are there braces but no semicolons? Brooklyn District Attorney Ken Thompson has indicted or obtained guilty pleas before indictment on the lowest percentage of felony complaints of any prosecutor citywide — a … 2011: Pearl | Clarification on terminating statements in the language specification. Ken Thompson (left) with Dennis Ritchie (right) Kenneth Lane Thompson (born 4 February 1943) is a computer scientist and winner of the 1983 Turing Award, together with Dennis Ritchie. [58] For example, the type keyword can be used to define a type for IPv4 addresses, based on 32-bit unsigned integers: With this type definition, ipv4addr(x) interprets the uint32 value x as an IP address. For example, if Shape, Square and Circle are defined as, then both a Square and a Circle are implicitly a Shape and can be assigned to a Shape-typed variable. It was written for Dennis and me and our group to do its work. [c] Go adds literal syntaxes for initializing struct parameters by name and for initializing maps and slices. They have also lived in Coolidge, AZ and Phoenix, AZ. November 2020 um 17:10 Uhr bearbeitet. 1978: Floyd | For 64-bit x86 systems, the following instructions have been added (see, This release includes a new code generation back end for 64-bit x86 systems, based on. Go 1 guarantees compatibility[37] for the language specification and major parts of the standard library. Thompson worked at Bell Labs for most of his career where he designed and implemented the original Unix operating system. [53][54][55], Pointers are available for all types, and the pointer-to-T type is denoted *T. Address-taking and indirection use the & and * operators, as in C, or happen implicitly through the method call or attribute access syntax. When explicitly converting a value from one struct type to another, as of Go 1.8 the tags are ignored. Other notable companies and sites using Go (generally together with other languages, not exclusively) include: The interface system, and the deliberate omission of inheritance, were praised by Michele Simionato, who likened these characteristics to those of Standard ML, calling it "a shame that no popular language has followed [this] particular route".[142]. Juli 1976 in New York City) ist ein amerikanischer Fusionmusiker (Saxophon, Klarinette, Komposition), der auch als Interpret Neuer Musik tätig ist. Go is syntactically very similar to C, but with memory safety, garbage collection, structural typing, and CSP-style concurrency. In Go 1.5, the order in which goroutines are scheduled has been changed. Kompiler dan IDE lainnya … 1983: Thompson, Ritchie | chan T is a channel that allows sending values of type T between concurrent Go processes. [51] Record types can be defined with the struct keyword. [70] Because interface{} can refer to any value, it is a limited way to escape the restrictions of static typing, like void* in C but with additional run-time type checks. He proved his genius at 'Bell Labs,' where he designed and implemented the original 'UNIX' operating system, regarded as one of the bedrocks of modern computing. The overhead of calls from Go into C has been reduced by about half. He said, "I'd spell creat with an 'e'." 1972: Dijkstra | Mathematical Go: Chilling Gets the Last Point Elwyn Berlekamp and David Wolfe Berlekamp and Wolfe presented a new paradigm, based on Conway's theory of partisan games, for evaluating late-stage Go endgames. The UNIX Command Language (1976) The UNIX Command Language is the first-ever paper published on the Unix shell. …our experience has been that programmers use them as a crutch to avoid thinking about proper error handling and reporting…. In 1.4, much of the runtime code has been translated to Go so that the garbage collector can scan the stacks of programs in the runtime and get accurate information about what variables are active. The grammar for method expressions has been updated to relax the syntax to allow any type expression as a receiver. Worked at: Bell Labs, Google. [74] The go get command can retrieve packages stored in a remote repository [75] and developers are encouraged to develop packages inside a base path corresponding to a source repository (such as example.com/user_name/package_name) to reduce the likelihood of name collision with future additions to the standard library or other external libraries. Go is a humanist sans-serif which resembles Lucida Grande and Go Mono is monospaced. Check back here for more music videos & interviews. [63]:284 Code using the empty interface cannot simply call methods (or built-in operators) on the referred-to object, but it can store the interface{} value, try to convert it to a more useful type via a type assertion or type switch, or inspect it with Go's reflect package. Ken Thompson is widely known as the protagonist of Cuckoo. Go now supports a more uniform and modernized set of number literal prefixes, Permits embedding interfaces with overlapping method sets[43], Module support in the go command is now ready for production use[43]. [4], Thompson entwickelte in den späten 1970er- und frühen 1980er-Jahren zusammen mit seinem Kollegen Joe Condon (1935–2012) den Schachrechner Belle, der 1980 die Computerschachweltmeisterschaft (WCCC) gewinnen konnte. As an alternative to C's three-statement for loop, Go's range expressions allow concise iteration over arrays, slices, strings, maps, and channels. Kenan Thompson was born on May 10, 1978 in Atlanta, Georgia, USA as Kenan Stacy Thompson.
