The Laws of Reflection - The Go Programming Language
Rob Pike 6 September 2011 Introduction Reflection in computing is the ability of a program to examine its own structure, particularly through types; it’s a form of metaprogramming. It’s also a great source of confusion. In this article we attempt to clarify things by explaining how reflection works in Go. Each language’s reflection model is different (and many languages don’t support it at all), b
The Go low-level calling convention on x86-64
Note The latest version of this document can be found online at https://dr-knz.net/go-calling-convention-x86-64.html. Alternate formats: Source, PDF. Introduction This article analyzes how the Go compiler generates code for function calls, argument passing and exception handling on x86-64Â targets. This expressely does not analyze how the Go compiler lays out data in memory (other than function arg
Bell Labs and CSP Threads
Introduction This page is a slice of the history of concurrent programming, focusing on one particular lineage of Hoare's language of communicating sequential processes (CSP) [1] [1a]. Concurrent programming in this style is interesting for reasons not of efficiency but of clarity. That is, it is a widespread mistake to think only of concurrent programming as a means to increase performance, e.g.,
Profiling Go Programs - The Go Programming Language
Russ Cox, July 2011; updated by Shenghou Ma, May 2013 24 June 2011 At Scala Days 2011, Robert Hundt presented a paper titled Loop Recognition in C++/Java/Go/Scala. The paper implemented a specific loop finding algorithm, such as you might use in a flow analysis pass of a compiler, in C++, Go, Java, Scala, and then used those programs to draw conclusions about typical performance concerns in these

go-ethereumOfficial Go implementation of the Ethereum protocol Geth (go-ethereum) is a Go implementation of Ethereum - a gateway into the decentralized web. Geth has been a core part of Ethereum since the very beginning. Geth was one of the original Ethereum implementations making it the most battle-hardened and tested client. Geth is an Ethereum execution client meaning it handles transactions, d
research!rsc: Go Data Structures: Interfaces
Go's interfaces—static, checked at compile time, dynamic when asked for—are, for me, the most exciting part of Go from a language design point of view. If I could export one feature of Go into other languages, it would be interfaces. This post is my take on the implementation of interface values in the “gc†compilers: 6g, 8g, and 5g. Over at Airs, Ian Lance Taylor has written two posts about the i

GitHub - gtank/cryptopasta: copy & paste-friendly golang crypto
TL;DR- Copy & paste your crypto code from here instead of Stack Overflow. This library demonstrates a suite of basic cryptography from the Go standard library. To the extent possible, it tries to hide complexity and help you avoid common mistakes. The recommendations were chosen as a compromise between cryptographic qualities, the Go standard lib, and my existing use cases. Some particular design
The complete guide to Go net/http timeouts
When writing an HTTP server or client in Go, timeouts are amongst the easiest and most subtle things to get wrong: there’s many to choose from, and a mistake can have no consequences for a long time, until the network glitches and the process hangs. HTTP is a complex multi-stage protocol, so there's no one-size fits all solution to timeouts. Think about a streaming endpoint versus a JSON API versu
