Padding is hard | Dave Cheney
Hmm, so some progress. We’ve managed to reduce the storage in the Go 1.5 64 bit case, but the others appear unchanged, especially Go 1.5’s 32 bit case. For the Go 1.5 64 bit case, the padding that we saw above is still there, but it has moved. Effectively what the compiler is seeing is this: type ProgInfo struct { Reguse uint64 // registers implicitly used by this instruction Regset uint64 // regi
Cross compilation with Go 1.5 | Dave Cheney
Now that Go 1.5 is out, lots of gophers are excited to try the much improved cross compilation support. For some background on the changes to the cross compilation story you can read my previous post, or Rakyll’s excellent follow up piece. I’ll assume that you are using the binary version of Go 1.5, as distributed from the Go website. If you are using Go 1.5 from your operating system’s distributi
Performance without the event loop | Dave Cheney
This article is also available in Japanese, イベントループなしでのハイパフォーマンス – C10K問題へのGoの回答 This article is based on a presentation I gave earlier this year at OSCON. It has been edited for brevity and to address some of the points of feedback I received after the talk. A common refrain when talking about Go is it’s a language that works well on the server; static binaries, powerful concurrency, and high per
gb, a project based build tool for the Go programming language | Dave Cheney
A few months ago I introduced gb as a proof of concept to the audience at GDG Berlin. Since then, together with a small band of contributors and an enthusiastic cabal of early adopters, gb has moved from proof of concept, written mostly on trains during a trip through Europe, to something approaching a usable build tool. This post gives an introduction to gb, and explains the benefits of adopting
