OK, so I have a project named golang_web_boilerplate in $GOPATH/src:

runtime.main: call to external function main.main

I'd bet that something is wrong with your go install. Double check you have not
set goroot, then delete your go install and start again from scratch.

I am trying write a small golang program which will periodically execute lsof
-i: to check number of open TCP connections at a port. Code looks
like below:-
package main
import (
"fmt"
"log"
"os/exec"
"strings"
"sync"
"time"
)

You need to pass the WaitGroup as a pointer. This way, connectionsCount
creates a WaitGroup, increments it's counts, passes a copy of it to count
and then waits on the original; count, however, only Done()s its copy.
go vet should probably complain about that, as it contains an appropriate
marker

Hello,
Is there a way to set up a vfs.NameSpace filesystem backed up by Windows
filesystem without specific root, something like:
ns.Open("C:\\foo\\bar") => content of C:\foo\bar
ns.Open("D:\\qux") => content of D:\qux
and so on. Why do I need it? Imagine a local file system backed by

So what I find out was that I was using Goose Database migrations in Go
code form (and so runtime.main warnings) - so tests were not run. If I
remove migration code, everything works. Will investigate this more later
today.

I just want to add that for mac/osx/darwin, in order to use an external

Hello all,
I am looking for feedback about Kafka consumer driver, that can allow "*At

Currently, from my point of view the only driver can manage this, it is

The survey that was recently posted here asked, among other things, what
changes to the language would be most useful. The one that immediately
came to my mind was getting rid of the need for redundant type specifiers
(examples below). It occurred to me that this must have been discussed

Hi,
I am sending a map of elements indexed by a bson.ObjecId(), coming from the
bdd.
type Stats struct {
A bson.ObjectId `json:"a,omitempty" bson:"a,omitempty"`
B map[bson.ObjectId]CustomType `json:"b,omitempty" bson:"b,omitempty"`
}

Not only was it discussed, it was tried, maybe in the run-up to Go 1. It
was a while ago, anyway.
But we found it made code harder to understand and brittle when you have
lots of fields, so the change was not rolled out. As is often the case,
what looks good for simple examples breaks down in the
Hi,
back on my initial question about compiling template, i m looking for some
experienced ideas.
I have now found out i needed to change the ast tree of template in order
to simplify it for later manipulation.
So for example i transform this

into
{{ $some := ("what
The first bson.ObjectID that you show isn't actually what is stored in the
object, but rather it is hex value of the object ID that is acquired by
calling
id.Hex()
It looks like that isn't what gets printed out when marshaling your map,
and instead the IDs are printed out as whatever the raw
Ok, thank you. I will try.

system, that kind of thing.

Thanks for confirming, I had thought it was the usual windows anti virus
issues, but that is not applicable if you are running linux.
Can you please provide a small runnable code sample that demonstrates the
problem.
