after reading https://golang.org/pkg/database/sql/, i'm still not quite
sure how to do error handling with respect to tx (transaction) operations.
coming from a java/c# background, where once an exception is raised, i know
what to do in the "catch" and "finally" blocks, i'm not as sure with go
This works:
b, a := 1, struct{ x int }{2}
But this doesn’t:
var a struct{ x int }
b, a.x := Returns1And2()
But this does:
var a struct{ x int }
var b int
b, a.x = Returns1And2()
And this does:
var a int
b, a := Returns1And2()

It is not a new declaration, it is definitely an assignment. This can be
determined because (in Go) a new declaration has effects when closing over
variables: https://play.golang.org/p/a_IZdOWeqYf
(ignore the obvious race condition; it works the same but looks uglier with
the requisite locks: h

That idea appears in https://golang.

I considered this option, but as Jakob mentioned earlier it would make the
Locker interface public.
Maybe consider making errFull or other
Has there ever been a discussion about allowing new identifiers *and
selectors *in short variable declarations?
var a struct { x int }
b, a.x := 1, 2
ERROR: expected identifier on left side of :=

I have web server serving requests from two domains: domain1.com and
domain2.com
The assets directories are different for the two domains.
webrootdomain1/assets
and
webrootdomain2/assets
How to make the handler for assets to serve different directory depending

the requests from different
Not exporting the mutex and other fields is a good consideration and
probably does apply here. I'll keep that in mind.
Thanks,

Yes. Just set the GOARCH env var to 386, and "go build" with that.

i have a 64bit windows 10 development machine. some of the machines in our
production environment are still 32bit windows 8.x and 7.x machines.
would it be possible for me to create exe's for those 32 bit machines from
my 64bit development machine? if yes, how?
