The encoding/decoding protocol is not stateless: the first time a new type
is seen, some type information is transmitted and the Encoder/Decoder
objects keep track of that. My guess is that the thing gets messed up by
the fact that you are encoding once and decoding twice.

I love playing with package reflect, which is much more powerful than
generics by the way (you can't implement gob or json with generics).

Seems to me that you didn't understand how to use sort, it's a bit
different from what you are used to in other languages. Take a look at the
examples in the package docs https://golang.org/pkg/sort/#example_

I suppose the error comes from the fact that you are using the 32bit
compiler. *i686*-w64-mingw32-gcc.exe is 32bit, try with
x86_64-w64-mingw32-gcc.exe
If CC is set correctly, cgo should use that. If you are worried that
gcc.exe is being used, temporarily move gcc.exe where cgo can't find it
Hi.
I'm looking at the source of mobile/gl.
If I understand correctly, it has a mechanism to reduce the number of cgo
calls: the gl calls are accumulated, until a "blocking" call is reached;
when that happens, all the calls with associated arguments are passed at
once to a C function, which

Maybe you can solve this with atomics.
You keep an int32 that acts as mutex (0 is unocked, 1 is locked),
the Trylock is done with atomic.CompareAndSwapInt32(mu, 0, 1) and the
Unlock with atomic.StoreInt32(mu, 0).
This gives you a Trylock, but you lose the standard (blocking) Lock.

This also works for implementing futures and it's simple, type-safe and can
be used with select:
https://play.golang.org/p/VDT36rC5A-
Of course the syntax is not as nice as built-in futures.

The panic you get is because CollectorGoogleAnalytics does not

"main" is also the name of the main function, maybe try with a different
one.

Hi everyone.
I thought I understood clearly how an RWMutex is supposed to work, but the
documentation is giving me some troubles.
It says: "The lock can be held by an arbitrary number of readers"
which is fine by me, but then the following statement seems to contradict
it:

If you don't care about preserving the order of the elements in the slice,
you can do something like this:

The functions I used are documented here: https://golang.org/pkg/reflect/

I should learn to read the questions more carefully before answering -_-
In the code you commented out, fd.Type() is a pointer type, so the zero
value of a pointer type is a nil pointer.
If you do fd.Type().Elem() it gives you the "dereferenced" type of the
value.
So, maybe you want:
v =
I suppose you want to allocate a new value, since fd is nil:
fd = reflect.New(reflect.TypeOf(fd).Elem())

If the initial slice ns has enough capacity, it will not be reallocated,
but only resliced and modified in place.
So, in your second example, ns1 and ns2 can end up being two slices that
share the same underlying array.
