Summary: 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.
+Summary: In the Google I/O 2010 podcast episode titled "Go Programming, " Rob Pike and Russ Cox discuss the unique features and principles of the Go programming language.

Summary: In the podcast episode titled "Rob Pike. Origins of Go Concurrency Style, " Rob Pike discusses the origins and concepts of concurrency in the Go programming language. He highlights the influence of Tony Hoare's paper on communicating sequential processes (CSP) in 1978, which emphasized communication and parallel composition of sequential processes. Pike describes CSP as a mathematical and elegant language that focuses on communication and synchronization between sender and receiver. Pike explains how processes can be combined in parallel, resembling a pipeline, and mentions the limitations of CSP, such as the inability to dynamically create processes or use send as a guard, and the lack of support for threads or mutexes. He also discusses the development of concurrent programming models and the emergence of the Occam language, which laid out the foundations for programming multi-processors and concurrent algorithms without the need for locks. The podcast episode also touches on the development of the Limbo language into Go, highlighting the power of Go's CSP model and its use of channels for communication and concurrency. Channels are described as first-class values that enable the transmission of data and capabilities between processes. Pike mentions the development of the lf language, which faced challenges due to its lack of garbage collection, but Limbo addressed these issues and became more successful in its limited domain. The benefits of using concurrency in programming are discussed, particularly in the context of the CSP model. Pike emphasizes how concurrency allows for efficient computation in areas such as cryptography and graphics, while also providing the opportunity for code reusability.
