Re: [go-nuts] Re: Whats the fastest cpu (per $) regarding golang compiler performance?

A lot of factors will affect compilation speeds. And scaling won't be linear by adding more cores, I know, but how well does the compiler already uses the available cores. How well does the compiler scale? The mentioned CL above will provide some nice performance increasements for multicore

Hi, What's the idiomatic way to name Go projects with multiple words? Would it be, - github.com/my-id/multiple-words, or - github.com/my-id/multiple_words, or even - github.com/my-id/does-not_care, or - github.com/my-id/InOneWord what's your preference and why? Thanks -- You received

There's definitely no idiom here. Do what the octokittens do and probably use the first or second option, in that order. The third seems awkward, unless the underscore has some specific meaning (like how _unix is used to compile architecture-specific code). And I'm not really sure if the

[go-nuts] Pointer to Container Type

In Go there is no way to pass a reference to an instance of the container/enclosing type, to a function of an embedded type. What work around do you use for this? Any idiomatic Go way? Currently I model the shared functionality using an interface. Then the implementation is another struct,

That's interesting, though quite different from the map implementation we're used to. Do you know (in any language) such an implementation, and would it really be as fast? Computing hash, accessing some bucket, and dealing with collisions seem unavoidable. But I have no idea of the extra

Hi all, I'm interested in the compiler performance of different cpus. How much impact has the number of cores? Or is higher frequency with a few cores better regarding compile time / $. Maybe someone already owns a new ryzen cpu. Is it worth buying a highend Intel cpu (i7 or xeon) for 1000$ or
