Hi everyone,
`go get` in Golang world has a simple way to fetch and install
binary
```
$ go get github/foo/bar.git
$ export PATH=$PATH:$(go env GOPATH)/bin
$ bar --help
```
This saves a lot of time and setup. Is that an alternative when
using dub?
Thanks a lot.

Hi,
I need to build some static binaries with LDC. I also need to
execute builds on both platform 32-bit and 64-bit.
From Docker Hub there are two image groups:

Which one do you suggest?
