but turned out to be a great general purpose language. True open source,all development is in the open,many contributors from around the world. News from a year of development,A web server written in Go. Deploying Go in production, Prerequisite some knowledge of web servers not much Go. Some big announcements and fun giveaways,Be sure to stay until the end. A year s progress,Windows supported, Our compiler ported thanks to our open source community.
especially, Alex Brainman Hector Chu Joe Poirier Wei Guangjing. Express Go an interpreter with JIT compilation,Ergo a new compiler for Windows under development. ARM port 5g is solid,GCC4 6 release includes gccgo. GDB has Go support,Starting program home r 6 out,Breakpoint 1 runtime throw s void at runtime c 97. 97 runtime throw int8 s,gdb info goroutines,2 waiting runtime gosched.
