[go-nuts] Go Performance

Hello Gophers, I’ve been chastised in the past regarding some of my Go performance tests - using Java as a baseline. In most of these micro-benchmarks Go has performed more poorly than expected. So, I ported nats (https://nats.io ) message broker (which is written in Go) to

[go-nuts] Invoke "go test" to execute exactly two specific tests?

Hi, I have a suite of 20 tests, each test corresponding to a function: func Test(). Out of the 20 tests, I have two specific tests: func TestXG() func TestNiceSystem() I want to invoke *go test -test.run* to execute exactly those two tests, and nothing else. How can I invoke go test

[go-nuts] uptick in sporadic travis failures for go package tests

Hi, I have seen an increase in sporadic error-out failure for our tests on the Gonum suite. This is usually due to a TLS failure early in the build resulting from a go get. For example ``` $ go get gonum.org/v1/tools/cmd/check-imports go get: warning: modules disabled by GO111MODULE=auto in

I think less and less people care about native UIs. This was not the case a few years ago, but nowadays web-like interfaces, even for desktop applications, is becoming the new standard. Most "non-tech" people interact with their computers mostly through the web browser, so a similar interface

Re: [go-nuts] How to get current goroutine id?

I agree. I’ve read the arguments against thread-local (or goroutine local storage), and the passing of Context everywhere instead. It doesn’t make sense to me. Even a simple runtime.GetGoID() that returned a unique int would allow the design of much simpler server software. But I don’t think

[go-nuts] Go 2 error handling non-proposal

What I like about error handling in Go is that errors are just values. Like any other values, they can be transparently stored, aggregated, passed around and used, among other things, to explicitly change program flow. That is why I am on the whole satisfied by Go 1's approach and a bit

[go-nuts] Re: Go2 proposal: remove := operator (or remove variable shadowing)

Yes, err handling is a part of variable shadowing mistakes. But it is not all such mistakes. I shadowed other variables at least as often as errors. воскресенье, 28 октября 2018 г., 21:42:54 UTC+3 пользователь Liam написал: > > Since most variable re-declaration is to support error variables,

The assumption that Fyne has made is that people care about speed and usability more than specifically native feel. The "native feel" on Windows is in transition anyway and both Windows and Linux already have multiple widget sets. Taking inspiration from mobile apps and material design it

Re: [go-nuts] Re: gomobile: what's the right way to make widgets?

As someone who lived through the criticisms of Java UI not looking native... I think those days are past, hopefully anyway, for the reasons others have cited. As long as the toolkit supports some “native” features like notifications, browser windows, system tray, etc. it shouldn’t be a big

Re: [go-nuts] Re: gomobile: what's the right way to make widgets?

The current Fyne backend is reliant upon the EFL project for rendering but it is written to allow other backends to be introduced (for desktop or beyond). You're right there is no API for platform specific stuff - if there is a use-case or a requirement it could probably be accommodated though.

A cross-platform GUI library is perfectly doable and cross-platform applications work fine enough for most use cases. Purebasic, REALbasic (now Xojo), Lazarus/Freepascal, Qt for C++ and Python, WxWidgets, Ultimate++, IUP, Swing, etc., all offer more or less cross-platform functionality. I'm

[go-nuts] Re: Go2 proposal: remove := operator (or remove variable shadowing)

Given all Go's narrow minded ideas for the sake of purity, := should be considered a vicious hack and removed from the language. Adding a simple var err At the top of a routine won't kill people. In my own experience, that construct is the single largest cause of trivial errors in Go
