### Core Authors

The Go language was created by Rob, Robert, and Ken initially because
Rob was bothered by slow C++ compiling times, talked to Robert, and luckily
Ken was in the next office.
Later, Ian joined the project after showing interest, and
wrote the [gccgo](https://github.com/golang/gofrontend).
Rob and Ken are retired. Robert and Ian currently work on adding generics
to Go. Russ is also one of the core authors of the project in the early stage.
Back then, he was a newcomer at Google, and Rob invited Russ for joining
the Go team since he knew Russ from way back because of the
[Plan 9](https://9p.io/plan9/) project. Russ worked on the early Go compiler, runtime, as well as the leap of
Go 1.5 bootstrap.
Now, Russ is the tech leader of the Go team.

Summary:In this Google Tech Talk from May 2007, Rob Pike, creator of UTF-8 and Plan 9 for Bell Labs, discusses his programming language, New Squeak, which features interesting mechanisms for concurrency and message passing. Pike argues that there are two ways to deal with the mismatch between the concurrent world we live in and the sequential computers we use to write programs: make the world look synchronous and sequential, or make software concurrent. Pike discusses the limitations of low-level concepts like threads, shared memory, and locks when it comes to programming for concurrency. New Squeak is a programming language that was created in 1988 to address issues that arise when writing software for a concurrent world. It has lambdas as functions, process management software, and channels as first-class citizens. The language inspired other languages and was used as a systems language at Bell Labs for a few years to build interesting tools. The talk focuses on processes and channels in New Squeak and how to write programs using these concepts. Channels are a communication tool used in programming that reduce the number of tokens needed for communication. Channels in CSP are introduced by the keyword Chan in New Squeak and are unbuffered synchronous communication ports that synchronize and communicate values between processes. New Squeak's channels and select statements enable potential communications and allow processes to block until one or more communications can proceed. The article introduces a simple language with n-way muxing and presents a program that prints sequential integers to a channel. It also explains the concept of a prime sieve and filter process to find all the primes that come out of a calculation. The system can also be used to manipulate power series. The article discusses the use of interfaces and channels in programming, with an example from the Newspeak language. The author discusses a system model used in building window systems in Plan Nine, which involves defining components as interfaces that capture communication and data flow through channels. This approach was used in all major user-level services in Plan Nine and was made easier by the author's previous experience with concurrency models in programming. The model allows for complex interactions between components and allows for composing interfaces themselves, rather than just state machines. The author also discusses the challenges of debugging concurrent programs and the limitations of CSP-like libraries for implementing select operations. They propose the idea of a shim interface that guarantees deadlock-free operation and can isolate and kill misbehaving clients. The Squint interpreter, a code from 1988, lacks many libraries for graphics and other functions. The idea of implementing a communication channel model on top of mutexes in C++ is discussed, and the cost of a channel versus a callback is debated. Optimizations can be made to generate more compact code for different forms of select.
