The slice which is created to be appended to b, points to &i, which (i)
gets updated in next (last) loop iteration.
Hence in last iteration, first element in `b` will start pointing to the
new array [4,5,6].
This could have been mitigated had `i` been allocated to new location on

I don't know if its a good idea to have this in stdlib, but you can

One other simpler (and not so elegant) solution is to use separate set for

@Bakul's solution sounds good but haven't tried to understand it clearly.

Interesting idea, Forud.
So I was reading net/http package, it has ResponseWriter which is an
interface as opposed to http.Request (which is a concrete type).
Then I wanted to know what all types implement http.REsponseWriter, which
reminded of your post here.
Is it possible to know this usi

Hi,
For a simple program:

}
I generate the core file using "gcore ".
Size of the core file is 1.1G.
Is that normal?

I think, this is what is happening.
I don't think this is a bug.
When server shuts down, it asks the kernel to release the resources it was
holding. One of the resources is port.
Though the program closed the port (by the shutdown()), but kernel still
keeps it in TIME_WAIT state. Now if w
If at any point it is to be checked that connection is active or not,
`Ping` can be used as stated by Shawn.
And any operation on dirty conn should fail, as the session is corrupt.
Though, it seems, auto-reconnection is already done by database/sql.

With a quick look, it seems "net" is not the only pkg which depends on
cgo, though by default it uses pure Go DNS resolver only.
I tested on small program:
package main
import (
"fmt"
"net/http"
)
func main() {
fmt.Println("Hello, playground")
http.ListenAndSe
Yes it will work as "x" is within scope.

Is the port 5000 on 192.168.153.239 open? If it is open, is your server
running on that port?

CMIIW, I doubt if it is explicitly needed to close the request's body in
handler, as it seems, close of request's body is handled by stdlib upon
completion of handler.
Handler, in net/http, is called

Interesting. Didn't know this was possible. Until now i used to fallback

Hi,
I have a doubt regarding use of enclosing function's variables inside
functions used as "deferred".
If function literal is used as "deferred" func (say foo), and it uses
enclosing function's variable (say x) as one of its arguments,
the value of x is "frozen" and func foo is called with t
