OpenSSL official release of the vulnerability warning, remind the system administrator to prepare for the upgrade of OpenSSL. The latest version of OpenSSL will be released on July 9 (Thursday) to fix an undisclosed high-risk vulnerability. Many security experts speculate that this high-risk vulnerability could be another " blood drops in the heart ". Mysterious high-risk 0day vulnerability OpenSSL is a widely used open source software library that uses SSL and TLS to provide encrypted Internet

Your program either has no data race, or its operations cannot be defined. In this example, Ben and Jerry's memory layouts match exactly, so in some cases it looks harmless. Imagine what a chaotic world would be like if they had different memory layouts (which was left to the reader as an exercise). The Go

This is a creation in Article, where the information may have evolved or changed. Summary: This article is compiled from Google chief engineer Rob Pike's speech slide, mainly on the part of Go design principles and intentions, but also refers to the use of the go language in and outside of Google's application status. But the purpose of this article is more about software engineering than programming language design, more precisely how to design a programming language to help software engineerin

This is a creation in Article, where the information may have evolved or changed. Go combines the easy-to-write features of dynamic languages with the high efficiency of static languages, with good ease of use and excellent execution efficiency. The Go language is originally designed to design Web servers, storage systems, and databases, and includes concurrent constructs in languages to help developers create parallel tasks. The go language has an extremely efficient compiler, and the go compil

, so we convert it to an unsafe before the function exits. Pointer (something equivalent to the void of C in Go ), use C.free to release allocated memory. One idiom is to immediately follow a defer after allocating memory (especially when the code is complicated), so we have the following print function: funcPrint(sstring) {CS:=C.CString(s)defer C. Free(unsafe.Pointer(CS))C.fputs(CS, (*C.FILE)(C.stdout)) } Build CGO Package If you use Goinstall, it is easier to build a CGO package, as long

2007, and later Ian Lance Taylor, Russ Cox, joined the project. The Go language was officially launched in November 2009 as an open source project and implemented on Linux and Mac OS X platforms, followed by the implementation under Windows. The predecessor of Go comes from Inferno (based on Plan 9 transformation). The Inferno contains a language called Limbo. Here is a quote from the Limbo paper: Limbo is a programming language for developin

He has worked with Thompson for many years and has been creating a widely used UTF-8 character encoding.Robert Griesemer: The hotspot compiler that

reduction of repetitive code for these algorithms also means that they are more tightly coupled, and if one of these algorithms needs to be modified later, it will affect other implementations of the algorithm, while certain repetitive code can maintain their independence. Russ Cox also gives a similar opinion:It is true that in other languages an abstract class with virtual methods can be used to eliminate such a small duplication of code, but it al

use of for-range. Now, without support for generics, a very friendly For-range still seems to be very difficult. D. Dynamic linking is not supported Currently go only supports static links (but Gccgo supports dynamic links, and go 1.1 may support some dynamic chains This is another contentious area. Arguments on both sides of the argument are dynamic Link/static link of excellent, missing Point, do not repeat here. E. Non-generic Most modern programming languages provide support for generics, w

1. Overview Go is an open-source programming language that makes it easy to build software that is simple, reliable, and efficient. Go was developed from the end of 2007 by Robert Griesemer, Rob Pike, Ken Thompson, and later joined Ian Lance Taylor, Russ Cox, and eventually open source in November 2009, A stable version of Go 1 was released earlier in 2012. Now the go development is completely open and has an active community. 2. Pros and cons 2.1 Adv

I'll translate. These days, 2X transistors! = 2x faster programs. more transistors = = more cores, but software have not evolved to being able to fully utilize more cores. Because Software today isn't able to adequately put multiple cores to work, the hardware guys was not going to keep putti ng more cores in. The cycle is sputtering.A Long term goal of Go are to reboot this virtuous cycle by enabling more concurrent, parallel programs. In the shorter term, we need
