Re: [go-nuts] Re: Why can't convert []T to []T2 if T2 is a copy definition of T?

It seems to me that this comes up often enough that it satisfies the definition of a FAQ. I know that https://golang.org/doc/faq#convert_slice_of_interface is commonly pointed to as an explanation, but it is not entirely satisfactory since it is talking about the specific case of []T to

[go-nuts] Performance Counters

I'm relatively new to Go, coming from a Windows/.NET background primarily. Does the Go runtime itself offer performance counters similar to what Windows makes available via perfmon? Specifically, I'm looking to capture realtime (not via a dump) metrics on heap usage, thread counts, GC

Re: [go-nuts] Re: Who wants to use Go to process your camera's raw files?

Klaus, thank you for your input and pointing us to RawSpeed. I glanced through it and noticed one of the approaches you take is to create decoders based on the "format" and use camera Make/Model tags to decide which decoder to use. I am glad to say this is also the approach I was taking and

[go-nuts] enabling HTTP/2 clients with some TLS settings using only stdlib?

Hey, I've not been able to figure out how to enable HTTP/2 in a net/http client that needs some tls.Config settings in its Transport (like it's needs a specific root added at run time) using only the stdlib. Is there a way to enable HTTP/2 on clients in the stdlib that I've missed? (Related: I

Re: [go-nuts] Re: ANNOUNCE: renderview

Alright, gotk3 appears to be working properly now. I found the right function - I had found set_surface_pixbuf in the GTK3 docs, but thought it missing from the gotk3, until a helpful page pointed out that it was *not* a Cairo function, and took the Cairo context as a parameter instead. So,

Re: [go-nuts] First tutorials for iranian users

Hi Erfan, This is cool! I skimmed through the videos. I think the videos are great for students learning Go as their first language. I read the intro page, and I think your reasons for "a bright future for Go" are reasonable but somewhat subjective. I think it would be useful to include why Go

Re: [go-nuts] Re: ANNOUNCE: renderview

I still have not tested on Windows; I did look up and find some documentation on how to get go and gtk installed and working together on Windows, and it basically boils down to installing the linux version of go under mingw. https://github.com/conformal/gotk3/wiki/Installing-on-Windows

Thanks for comments. The status00 should be not-buffered (status00 = make(chan *Data)); was rate limiting on two channels. On Sunday, August 28, 2016 at 8:16:50 PM UTC+4:30, Henrik Johansson wrote: > > The race is between the len call and the use of the channel. Entries can > have been added in

Re: [go-nuts] Length of Channel Using len Function

Using len(ch) like this in a concurrency scenario is a big no because then the value you get carries 0 bits of useful information. It's not a data race, it's worse, the race is semantic and not fixable without removing the use of len(ch). On Sun, Aug 28, 2016, 17:26 dc0d

agree with Korshak above In fact T L's experience reminds me very much of probably my first experience with go .. I had read the specification completely, and I thought 'thoroughly' - then immediately tried this : https://play.golang.org/p/or1Ikhr4en package main import ( "fmt" ) func

Re: [go-nuts] Re: Why can't convert []T to []T2 if T2 is a copy definition of T?

I think that your original interpretation of TL's questions is the correct one, and the one that I read when I read all of this posts. I don't think that it's a fair characterisation that he is asking about possibility rather that design, even in the post that this was a reply to. I can
