Not quite exactly. One item per scheduler (could be count as native thread) is
stored in fast thread local storage. Yes, there are still locks, but for
separate lock per thread, and this is quite cheap, since

You might want to read about slices and arrays in go:

Could you please explain, why primes[6:6] okay, but primes[7:7] not? *:-)*

Hi all -
I'm trying to connect to ptp4l socket (/var/run/ptp4l) to collect stats
for PTP delay and RMS.
current code/snippet allows me to connect :
conn,err := net.Dial("unixgram","/var/run/ptp")
but i cannot write properly to the connection (conn). I seem to get an

I'm sorry Isaac, I meant multi-language benchmarking generally, nothing
about the specific case you mention so i was slightly tangential to your
original post.

I haven't been able to find a Go example of this being used so far.
However I found a C example that I'm porting over to Go that access the
microphone.
All I'm doing so far is 'al.OpenDevice()'
running 'gomobile build' generates this error:
Is there a more concise way to write
var check = 1 + self.left.itemCheck() + self.right.itemCheck()

pool.Put(self.right)
self.right = nil
return check

Hello,
When you use the colon, you taking a subset of the data. Further, the
notation is a closed/open. So a slice primes[6:6] is all of the element in
the array with index >= 6 and index < 6, which is an empty set. Note that
the type of the expression primes[6:6] is []int.

Hi.
The code like below:
package main
import "fmt"
func main() {
primes := [6]int{2, 3, 5, 7, 11, 13}
fmt.Println(primes[6:6]) . // *OK*. return: []
//fmt.Println(primes[6]) . // fail. out of bounds...
}
Why?
Is the golang grammatical feature? or anything else..
Any help, please!
