[go-nuts] Estimating blockers for supporting gollvm on RISC-V (qemu). Fedora 33

Hello. It is just a brief survey - but I am currently dealing with a messy setup, for qemu. I have upgraded, after bootstrapping( the manual ) and I am able to boot > Fedora (5.8.0-1.0.riscv64.fc33.riscv64) 33 (Rawhide)

Hi Paul! Thanks for pointing play-with-do service. It's cool. But I'd want something less lowlevelish. I only want user to fill a form with code to run, plus some dependencies declaration if needed. Boom! Dependencies are installed, code is executed. You've got your report to share. You could

[go-nuts] [generics] generic types join through pipes

Good evening, First of all, thank you for everything you do with Go! I've had an idea for generic for Go for some time. If it makes no sense, please ignore my email. The idea is to join the different types through a pipe. This means you do not have to introduce a 'type' in the interface. It

[go-nuts] Online service to run Go code with Go modules support

Hi go devs. I am thinking about brining up a service that would execute Go code with support of third party modules, so that both Go modules developers and users could play with a code and get immediate results without having any Go environment, through a browser. I've noticed that there are

Re: [go-nuts] Ballooning Executable Sizes

Yes. Thanks for your help. I've been reflecting on this and I have a couple of observations: 1) In some ways, the suddenly bloated executable is useful because, as in this case, it points to a design flaw in the program. 2) However, it was some weeks before I noticed that a problem had arisen

[go-nuts] Carting int to bool and the reverse for bit hacking ?

Go has a strict type separation between int and bool. For a normal usage this is OK. I guess it also ease assembly portability because there is not always a machine instruction to do so. For bit hacking, this is an unfortunate limitation. A handy feature of bool <-> int conversion is that

[go-nuts] How to detect if transport connection break

Hi, My basic understanding of HTTP protocol is that an HTTP client sent request, get response from the HTTP server and then the connection is closed. My question is how can an HTTP client detect if the underling transport connection break. For example if the HTTP server shutdown, is there a
