Hi, all
I have a C# code to decrypt data as following
public static string test(string input, string key)
{
if (((input == null) || string.IsNullOrEmpty(input.Trim())) ||
((input == "false") || (input == "null")))
{
return string.Empty;
This would probably introduce unnecessary confusion. People are used to the
equality operator comparing values in go, as opposed to references. It's
much better if the slices finally support the equality operator, even
though the comparison speed will depend on the number of items in the
slices
I want a single instance of a client handle to be initialized.
Is it ok to declare the instance as
var client MetricsClient
and then initialize it using sync.Once().
Is it required for some reason that the client be a pointer or are there
are other issues with it. My requirement is to be able
numBytes, err := downloader.Download(os.Stdout, &s3.GetObjectInput{ ... })
Should do it.

Thanks! I'll study these examples and see how they apply. I generally don't
use such big numbers, however, I may break it over sets of numbers which
could distribute the work more evenly.

Hi all,
I am new to go language.
Now I am trying to develop a GUI tool with go.
Are there any good choices such as QT or others to make the GUI
Thanks

Try using os.Stdout as the download target.

So that it becomes valid map inputs.
What should be hashed would be the slice/map/ref type value.

You're welcome. I think that using empty interfaces isn't the best way to
do it. I meant (but didn't specify) that you should make an interface that
both of your struct types satisfy, and return those instead.

Shawn,
Thanks, it was an error on my side. The function actually returns an array
of structs but an interface is not an array, so when I tried to return an
array of interfaces, it crashed. I changed it from []interface{} to
interface{} and it's working.
Thanks for the help.

Just been thinking that since a slice is a "reference" type, why not allow
slice equality?
Of course the number of cases where two slices are equal would be quite
low, irrelevant of whether the view they have on their respective arrays is
the same.
