It seems that pass *n's address *in the code above will make a data race,

unavoidable. Just as specific background this is happening for me on tests
of vectors (lines) intersecting with bounding boxes (ie oblongs, axis

Don't you mean bottom? At the top, the ListenAndServe will not return,
so the HandleFunc call will never be made, so you will always get 404.

Move http.ListenAndServe to the top of the main() function, outside the
http.HandleFunc call and it will work.

The ListenAndServe shouldn't be in the handler function.
When you run this app, does it exit immediately? Because it looks like it
exits immediately. Not serving anything.

Hi all,
My apologies; I very well understand that the answers to my question here

I feel Websockets is really cool and I have used it for IPC between non-web
applications. Certainly

It's implementation dependendent. Be explicit. For example, pass a flag

How to find out if the *main* function is started by executing the compiled
binary or by *go run*?
By examining *os.Args* it can be seen at the first case (running the app)
we will have the *binary name* as the first argument without any path and
when it is started using go run, we will have so
Actually, the issue is not the template but my logger. The logger is
writing to os.Stderr for some reason that's not preserving new lines but if
i do fmt.Println then the new lines are preserved. Pretty sure i've made a
simple error here and need to investigate more.

Hi all,
Say I have the following struct:
type Info struct {
Summary string
Descstring
}
And this is the template string
tmplStr = `Summary={{.Summary}}, Desc={{.Desc}}`
If the value of Desc has newlines, it looks like the template engine strips
those out and replaces th

I'm hoping to avoid using a network LB since we are operating over https so
that means we'll have to terminate SSL ourselves (which means distributing

A slice shares enough properties with string to make + intuitive.

To me the ++ operator (and +=) operator for slices are intuitive too.
