This is because zero values are not sent by encoding/gob. So the false
value never goes over the wire to overwrite the true. If you want
things to be zeroable, you need to do that yourself before decoding.
From https://golang.org/pkg/encoding/gob/#hdr-Encoding_Details
"If a field has the zero
It seem if a field with boolean value setted to "true", some how gob Decode
cannot change it to false.

I'm looking at adding a timeout option to my GoAWK script interpreter using
either a timeout or a context value. This is mainly for safety when using
it in an embedded context, for example to avoid someone doing a
denial-of-service attack by submitting a `BEGIN { while (1); }` script.

I see, thank you very much!

The parameter to fmt.Println is evaluated at the time of the defer
statement's execution. You should do something like this instead
func main() {
start := time.Now()
defer func() { fmt.Println(time.Since(start)) }()
time.Sleep(10)
fmt.Println("Hello,
For the following piece of code.
func main() {
start := time.Now()
defer fmt.Println(time.Since(start))
time.Sleep(10)
fmt.Println("Hello, playground")
fmt.Println(time.Since(start))
}
The output is:
Hello, playground

When web-apps are implemented in scripting languages which suffer from poor
performance,
it is common practice to proxy them behind a "real" web server such as
nginx, and offload SSL

This is a topic that has confused me in the past. In the simple case where
you build a Go executable and get requests from it directly, your Go
application *is* your web server. However, it's common in industry to put a

The error is correct. See https://golang.org/ref/spec#Conversions
A constant value x can be converted to type T if x is representable by
a value of T.
An integer cannot represent the value 6.6 hence the
Hi,
does this should work ?
package main
import (
"fmt"
)
func main() {
const (
c = 2
z = 3.3
y = c * z
x = int(y) // or x int = y
)
fmt.Println(x)
}
it does not compile with error:
constant 6.6 truncated to integer
