Qihoo 360 and Go - The Go Programming Language
Yang Zhou 6 July 2015 This guest blog post was written by Yang Zhou, Software Engineer at Qihoo 360. Qihoo 360 is a major provider of Internet and mobile security products and services in China, and operates a major Android-based mobile distribution platform. At the end of June 2014, Qihoo had about 500 million monthly active PC Internet users and over 640 million mobile users. Qihoo also operates
Go 1.4 is released - The Go Programming Language
Andrew Gerrand 10 December 2014 Today we announce Go 1.4, the fifth major stable release of Go, arriving six months after our previous major release Go 1.3. It contains a small language change, support for more operating systems and processor architectures, and improvements to the tool chain and libraries. As always, Go 1.4 keeps the promise of compatibility, and almost everything will continue to
The Go image/draw package - The Go Programming Language
Nigel Tao 29 September 2011 Introduction Package image/draw defines only one operation: drawing a source image onto a destination image, through an optional mask image. This one operation is surprisingly versatile and can perform a number of common image manipulation tasks elegantly and efficiently. Composition is performed pixel by pixel in the style of the Plan 9 graphics library and the X Rende
go fmt your code - The Go Programming Language
Andrew Gerrand 23 January 2013 Introduction Gofmt is a tool that automatically formats Go source code. Gofmt’d code is: easier to write: never worry about minor formatting concerns while hacking away, easier to read: when all code looks the same you need not mentally convert others’ formatting style into something you can understand. easier to maintain: mechanical changes to the source don’t cause
Defer, Panic, and Recover - The Go Programming Language
Andrew Gerrand 4 August 2010 Go has the usual mechanisms for control flow: if, for, switch, goto. It also has the go statement to run code in a separate goroutine. Here I’d like to discuss some of the less common ones: defer, panic, and recover. A defer statement pushes a function call onto a list. The list of saved calls is executed after the surrounding function returns. Defer is commonly used t
Go 1.2 is released - The Go Programming Language
Andrew Gerrand 1 December 2013 We are pleased to announce the release of Go 1.2, the latest stable version of the Go Programming Language. Binary distributions may be downloaded from the usual place or if you prefer to compile from source you should use the release or go1.2 tags. This new release comes nearly seven months after the release of Go 1.1 in May, a much shorter period than the 14 months
Text normalization in Go - The Go Programming Language
Go’s approach to normalization As mentioned in the strings blog post, Go does not guarantee that characters in a string are normalized. However, the go.text packages can compensate. For example, the collate package, which can sort strings in a language-specific way, works correctly even with unnormalized strings. The packages in go.text do not always require normalized input, but in general normal
Four years of Go - The Go Programming Language
This chart shows the growth of Google searches for the term “golang” over the past four years. Notice the knee in the curve around March 2012, when Go 1.0 was released. If these searches are a decent proxy for interest, then it’s clear that interest in Go has grown remarkably since launch, and particularly so in the last 2 years. But where is the interest coming from? The open source community has
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 turns three - The Go Programming Language
Russ Cox 10 November 2012 The Go open source project is three years old today. It’s great to look at how far Go has come in those three years. When we launched, Go was an idea backed by two implementations that worked on Linux and OS X. The syntax, semantics, and libraries changed regularly as we reacted to feedback from users and experience with the language. Since the open source launch, we’ve b
Go version 1 is released - The Go Blog
Today marks a major milestone in the development of the Go programming language. We're announcing Go version 1, or Go 1 for short, which defines a language and a set of core libraries to provide a stable foundation for creating reliable products, projects, and publications. Go 1 is the first release of Go that is available in supported binary distributions. They are available for Linux, FreeBSD, M
Building StatHat with Go - The Go Programming Language
The web application service is multi-tiered. The web server processes all requests and sends them to an interactor layer. For simple tasks, the interactor will handle generating any necessary data. For complex tasks, the interactor relies on multiple application servers to handle tasks like generating graphs or analyzing data sets. After the interactor is finished, the web server sends the result
From zero to Go: launching on the Google homepage in 24 hours - The Go Programming Language
The program’s request handler parses the URL to determine which element is selected for each component, draws the appropriate images on top of the background image, and serves the result as a JPEG. If an error occurs, a default image is served. There’s no point serving an error page because the user will never see it - the browser is almost certainly loading this URL into an image tag. Implementat
The Go Programming Language turns two - The Go Programming Language
Andrew Gerrand 10 November 2011 Two years ago a small team at Google went public with their fledgling project - the Go Programming Language. They presented a language spec, two compilers, a modest standard library, some novel tools, and plenty of accurate (albeit succinct) documentation. They watched with excitement as programmers around the world began to play with Go. The team continued to itera
Share Memory By Communicating - The Go Programming Language
Andrew Gerrand 13 July 2010 Traditional threading models (commonly used when writing Java, C++, and Python programs, for example) require the programmer to communicate between threads using shared memory. Typically, shared data structures are protected by locks, and threads will contend over those locks to access the data. In some cases, this is made easier by the use of thread-safe data structure
