Can't believe the book is named with "Golang"!

I believe you only need one or the other; I assumed a use case like this:

Do any of them even do client pooling? I would be interested to know. I've
had to handle my
SHA256 (SHA in general) has a precise behavior if you wanna hash a number
of bits not multiple of the block (512bit)
Sha256.go handle this correcty ONLY in the case that you input is at least
multiple of 8 bits.
If you wanna hash, say, 20bit (0xABCDE) you cannot obtain a correct result.

I found a good discussion in the FAQ that explains the problem clearly.

I think the mutex is needed on the update function with or without the use
of sync/atomic. The atomic guards the Load and the Store but the func is
operating on the
Good to know about not needing sync/atomic. I used a pointer to an
externally defined mutex because an answer I found on StackOverflow
recommended doing that. However, on looking at my application more closely
I think you're right about putting it inside the struct.

Sorry it took so long for this post, other things intervened. Anyway, quick
responses to the three people who commented.
Shulhan, there is a better mechanism in Go than resetting the buffer. Have
a second variable, say "var message []byte", and then after the call to
ReadMsgUDP add this line
I don't know if it's documented or not. In the language reference you can
see the rules for method calls:

A hint might have been that object should have mutated, but it didn't.
It's in a class of errors that becomes
I actually find it useful to have these posted here. I'm a notice Go

I also saw a reference to "Hands On GUI Application Development in Go,"
which I'm starting to read now.

I'm clearly missing something about the way sync.Mutex and atomic.Value
work in Go.
I'm attempting to write a pair of concurrency safe methods, load() and
update(), for accessing a struct. The struct is stored as an atomic.Value
and accessed with
In Go, you can simply create a CreateDatabase() function which initializes
your prepared statements, in lieu of the constructor.
When doing a SQL query, you must use the correct prepared statement for it,
so whether you have an array of them, or each is its own field, each
handler would have to
Hi Marcin,
I know about Prepare function supported by sql package .My initial question
was what is better way to pass multiple prepare statements on different
http handlers .
ex: we can construct struct like this
type Database struct {
db *sql.DB
someStmt *sql.Stmt
// etc.
}
but
which is best thrift client pooling driver supported in golang (means which
is optimized according to performance )
