Hi,
I started learning about Go assembler and I'm having problems with the
NOSPLIT symbol, which makes the compilation fail with error message:
"illegal or missing addressing mode for symbol NOSPLIT"
I've found a blog post which describes the same problem and proposes
removing the symbol in order
Thank you very much Ian, I didn't notice the imported headers file in the
examples I was looking at. My code is compiling perfectly fine after I
added that line.
Cheers,
Pablo

Hi gophers,
I have created a new library reusing some code from the Go standard
library. I want to make this project open source and I would like to know
if there are requirements in terms of the license for this software.
Should I use the same Go BSD license, use BSD without mentioning the Go

Thank you Lutz, then, if I understand this right, new projects containing
parts of Go code have to include the original Go BSD license.
There are a couple of aspects that remain unclear to me:
- The copyright notice, list of conditions and disclaimer have to be
included in every file of the pr
Thanks Ian, that is very helpful. I've also googled for reusing BSD
software and, as you said, there is plenty of information.

This is awesome, thank you all very much for the background information and
great examples that you've provided. I think it is quite clear now what the
difference is between these two runtimes.

I have seen Go code using this function to find out the least significant

func LSB(ci uint64) uint64 { return uint64(ci) & -uint64(ci) }
This function works fine but I wonder why, if call the same AND operation,
it results in an error: "constant -X overflows uint64"

Thanks Matt. That's a very good explanation about the internal bit
representation of integers and answers perfectly my question. I really
appreciate your help in understanding these operations.

Thanks for sharing. You might be interested in this nice implementation of
the same game implemented by the Go team a few years ago. It contains a
great demonstration of hoe to solve this problem elegantly using functions
as returned values:

Hello,
I'm curious to know if this is intended:
https://play.golang.org/p/t353t8ZvL1
Line 9 is formatted with spaces but line 10 has no spaces. It seems like
adding +1 to the expression changes the behaviour of "gofmt". Wouldn't it
be simpler for "gofmt" to always add spaces between the operator

I'm trying to understand how the 'select' statement works internally. The
execution process of select as described in
https://golang.org/ref/spec#Select_statements says on number 2: "If one or
more of the communications can proceed, a single one that can proceed is
chosen via a uniform pseudo-rando
Thanks Dave. It seems though that whatever select chooses to run (A or B)
the program takes 1000 ms to complete. I would expect the program to finish
in 100 ms if A is chosen or 1000 ms in the case of B. I wonder if both
functions are evaluated concurrently no matter which case select chooses.

Hi Mark,
I can also suggest you to look into the open discussion that's currently
happening on how multidimensional slices should be implemented in future
versions of Go. I particularly find that area and the proposed ideas very
interesting:

Hi gophers,
I'm designing a service exposed through a http server which uses a pool of
workers to process requests. At the moment my handlerFunc look similar to
this:
func aHandler(w http.ResponseWriter, r *http.Request) {
var wg sync.WaitGroup
wg.Add(1)
reqQueue <- &Reque
Thank you Tamás,
I like the concept of blocking on select in the handler until a worker
closes the channel. I don't know why but every time I use a WaitGroup I
have the impression that the same thing can be done better.
I'll try to implement it with the context library first as I'm very

I've seen this question asked before in the mail list but with no clear
answers. I'm just asking it again in case someone has come up with a new
way of doing this:
Does anyone know about a good tool or method to detect memory leaks
happening on C code being called by cgo?

Hi,
I'm confused with image.Gray16 having pixel values represented in the wrong
order. It seems to me that image.Gray16 considers numbers to be big endian
instead of little endian.
I've created a small playground example to illustrate this:

Is there something

That's great news Chris! Is it documented anywhere with some more detail this
pure Go implementation? I'd love to know more about how you overcame the
initial problems such as external code execution that lead you to choose LuaJit
in the first place.
Thanks,
Pablo

Hi,
The rpc documentation says that a remote rpc method can be registered if
the second argument (response) is a pointer.
https://golang.org/pkg/net/rpc/#Server.Register
Does anyone know if there is a way of having an interface declared as this
response type and then assign pointers to it that s
Hi gophers,
I'm using netutil.LimitListener to limit the number of concurrent requests
that can be handled in a server to limit the memory usage of the service.
I've noticed that when I send a bunch of requests it serves the number
passed to the LimitListerner but after that it serves n-2 requests
I'm thinking about the possibility of having something like [][]Volume in
Go. Do you know the size or number of Volumes in your struct?
There's an example of converting **char into []string that might be useful:
