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 this episode, Chris Manghane from the core Go language team at Google provides a brief overview of gccgo, also known as "the other Go compiler. " Gccgo is a Go compiler that utilizes the power of GCC for compilation and optimization. It was written by Ian Lance Taylor and released in November 2009, and it is still actively maintained by him. Manghane explains that the decision to develop gccgo using C++ and targeting GCC was made because GCC supports a wide range of architectures and offers extensive capabilities in code analysis, optimization, and generation. By using GCC as a compiler, technical honesty is promoted, as it avoids dependence on a single implementation. Additionally, having multiple implementations of a product helps identify flaws and improve designs. However, gccgo faces challenges in achieving feature parity with the go compiler. It has an outdated garbage collector and experiences delays in updates. Version 1. 4 brings changes to the C runtime and the way the garbage collector expects type information. The shift from segmented to contiguous stacks also poses challenges, as current C compilers do not support the necessary precise control and use of stack knives. Despite these challenges, gccgo has seen significant improvements, becoming separate from GCC and offering greater flexibility. The implementation of LLVM has resulted in a more efficient compiler. The use of Portable Native Client allows for running native code in web browsers, leading to increased adoption of Go. Manghane emphasizes the importance of catching up with the go compiler and experimenting with features like generics. He also highlights the need to improve basic tools, particularly in authorization and book compilers. Minimizing garbage collection overhead is crucial, and stamp analysis is proposed as a method to enhance the performance of the garbage collector. The ultimate goal is to achieve a more efficient and versatile garbage collector. Additionally, the language fancy power has the potential to improve binary generation and inspire improvements in the go compiler.
Summary:In the GopherCon 2017 episode titled "The New Era of Go Package Management, " Sam Boyer discusses the importance of package management in software development and the transition towards official tooling. He emphasizes the need for a common language in the software ecosystem to effectively share code and improve collaboration. Boyer acknowledges the challenges of dependency management in Go programming, such as the lack of emphasis on releases and potential conflicts with the go get tool. However, he highlights the Go community's culture of caution and thoughtfulness when dealing with dependencies. Various tools, including Goep, Glide, and GB, have been developed to address reproducibility and versioning issues. The introduction of the vendor directory in 2015 improved dependency management but also introduced new challenges. To address these issues, a committee was formed, and GitHub Depp was introduced as an official experiment in dependency management. Depp relies heavily on community participation and follows a two-file system using a Toml file to declare rules and constraints. It generates a lock file for reproducibility and follows semantic versioning. Boyer also mentions Digby, a package managing gopher that aims to integrate relevant behavior into the tool chain. The development of the Go tool chain involves experimentation and mapping to ensure a clear transition. Boyer emphasizes the importance of community participation and support in the success of these tools. Overall, the Go programming language offers effective dependency management tools and owes its success to the contributions and support of the community.
Summary:In this episode of dotGo 2017, Sam Boyer discusses the functional design principles behind dep, a dependency management tool for Go. Despite Go not being a functional language, Boyer demonstrates how principles from functional programming can be leveraged to design efficient and effective Go programs. One key concept Boyer explores is memoization, a technique that improves the performance of functions by caching their results. He explains how memoization can be applied to the Fibonacci sequence, reducing the number of function calls and improving computation time. By storing previously computed values, the time complexity of the function is reduced to O(n). Boyer emphasizes the relevance of memoization in avoiding unnecessary work and highlights dep ensure as a key function in the code. Boyer also delves into the topic of dependency management in Go. He explains that dependency managers map project source code to its dependencies, adding metadata to describe desired sources. He discusses the two notions of 'should' for dependencies: looser constraints and stricter reproducible builds. Go uses static analysis to map project source to manifest, and the relationship between project source, manifest, and lock files is crucial. Boyer explains how the depth model analyzes import statements and uses the go package Tommo to create a lock and populate the vendor directory. Overall, Boyer emphasizes the importance of designing transparent and error-free systems with valid inputs and outputs. He suggests that exploring different programming models, such as functional programming and actor models, can lead to innovative and beneficial systems. By applying principles from functional programming, even in non-functional languages like Go, developers can create more efficient and effective programs.
Summary:In the episode "Building Predictability into Your Pipeline, " Pete Garcin from ActiveState, Sam Boyer from Stripe, Russ Cox from Google, and Jess Frazelle from Microsoft discuss the challenges and solutions related to reproducible builds, environment configuration, and dependency management. Dependency management has been a long-standing problem in software development, but Go has made improvements with code hosting site import paths and the introduction of vendor directories. Tools centered around vendor directories, such as DEP, have been widely utilized in production. However, the availability of updated data on its usage is limited. The adoption of semantic versions and the need for clear documentation and user-friendly interfaces are ongoing areas of improvement. Implementing dependency management in the build pipeline has resulted in significant improvements for large projects like Kubernetes. Vigo, a new tool that provides an alternative solution for package management in Go programming, has proven to be highly efficient and capable of handling complex environments. However, the use of symlinks in Kubernetes has caused some problems. Vigo is gaining traction and being adopted by major projects. Reproducible builds ensure consistent deployment of applications, and containerization offers a solution by providing a consistent environment for application deployment. Transitioning to containers has benefits, such as easier updates and maintenance, but it requires effort to change workflows and specific tooling for integration with CI/CD processes. Optimizing container images and reducing dependencies are crucial for performance. Language package managers play a crucial role in software development, and verification steps ensure integrity. Proxy support for the system is a challenge, as companies want to ensure package stability and security. Ongoing work is being done to improve tooling and verification methods, with Microsoft's open source team involved in the development process. The adoption of Go language faces challenges due to its perception as a bleeding-edge technology. To address this, changes are being made to introduce package management and versioning, crucial for reproducible builds and compatibility. Gathering community feedback is essential before implementing these changes, and an official go proposal will soon be initiated. Overall, the experts emphasize the importance of reproducible builds, clear documentation, user-friendly interfaces, and community engagement to overcome challenges in adopting Go and ensure predictability in the software development pipeline.
Summary:In this episode of Computerphile, Professor Brian Kernighan discusses the creation of the book "C" Programming Language. The book, co-written by Kernighan and Dennis Ritchie, is a comprehensive guide to the widely used programming language. Kernighan explains that the development of "C" was influenced by the MULTICS project, which aimed to create a computing utility. Ken Thompson and Dennis Ritchie, who were involved in MULTICS, went on to develop UNIX, a stripped-down operating system. They experimented with high-level languages and created B, a precursor to "C". "C" allowed the operating system to be rewritten in a high-level language, making it more understandable and portable across different architectures. The book, published in 1978, included mathematical expressions and tables, and went through multiple editions. Kernighan also mentions that he wrote tutorial documents on programming languages B and "C" due to market demand. He convinced Dennis Ritchie to co-write a book on "C", combining the tutorial document with Ritchie's reference manual. The book became a definitive guide to "C" and played a significant role in the language's widespread adoption.
