Re: [go-nuts] Generics are overrated.

Generics is a non essential feature in that you can live without it. However, it is not without merits. Generics is a bridge to higher level expressions. If Go wants to add "modern" features in the future, it will stumble upon the need for generics in one way or another. While simple, code dup

[go-nuts] gopherjs files, writing, loading

Since javascript in a browser is a local jail of sorts, what is the best way to save local files, write to them, load them? What even happens if you use go input/output and write to a file? I see that there are localStorage api bindings for gopherjs, so that project must have figured a way to s

[go-nuts] Re: 10x latency spikes during GC alloc assist phase

Thanks a ton! We (at Laserlike) gave this a try and it basically cured our problem in one fell swoop. The GC cycles now take longer to run, especially under load, but memory growth isn't too bad. I know that Go's philosophy is not to add knobs to the GC, but there really needs to be a way to t

Re: [go-nuts] go get and protos (protoc; grpc)

The consensus seems to be to generate and checking artefacts such as this. It does help with reproducibility and doesn't force the enduser to install all kinds of possibly weird tools. fre 28 juli 2017 kl 20:46 skrev 'Laurent Demailly' via golang-nuts < golang-nuts@googlegroups.com>: > This might

[go-nuts] go get and protos (protoc; grpc)

This might be a FAQ or just my newcomer to go lack of knowledge, please kindly point me in the direction if this is the case: Is there any way today or work in the future to make "go get" work with projects that have .proto files, without checking in the .pb.go generated file ? (ie have "go get

[go-nuts] Worker pool library.

I wrote something up for a personal project and I thought this might be useful to some of you: https://github.com/brunoga/workerpool This tries to simplify executing the same task of a set of items in parallel. It does all the expected stuff from this kind of library and also accepts a context wh

Re: [go-nuts] In memory compilation and execution of Go code

OK, but what about to use the compiler and tune it to take a string instead of a file or something like that? Or compile a function in runtime? I look into https://github.com/cosmos72/gomacro and https://github.com/go-interpreter/ssainterp but seems to use reflection to create a class and are

Re: [go-nuts] Generics are overrated.

The build time issue is an artifact of C++ and templates. When generics were introduced to C# 2.0, they did do not negatively affect build times. On Friday, July 28, 2017 at 6:41:56 AM UTC-7, Robert Melton wrote: > > My primary concern about generics is they may significantly hurt build > times,

Thanks for your reply! But I was trying to measure the time difference between the SYN and SYN-ACK. Even though it may not be exactly accurate but getting packets out-of-order makes the whole idea moot. On Friday, July 28, 2017 at 2:26:28 AM UTC-4, feilengcui008 wrote: > > Not sure whether und

Re: [go-nuts] Generics are overrated.

My primary concern about generics is they may significantly hurt build times, which coming from C++ I am rather sensitive about. Beyond that I am worried that they might end up NOT being an improvement over all the tools that have already popped up to handle this problem. There are a lot of wa

Re: [go-nuts] Generics are overrated.

I programmed in about a dozen different languages before Go. None of them had generics. I use Go, love it, and never noticed anything missing when I write everything from command-line tools to complex servers. I've always been puzzled when people represented the lack of generics to be a flaw in Go,
