Hi, guys.
I've recently written an authentication/authorization plugin for mosquitto,
a well known open-source MQTT broker, using cgo. The basic idea was to
export some Go functions to mosquitto's C plugin interface, and write all
the logic in Go. It implements a bunch of backends available, an

Hello Gophers,
Just announcing my graph database called Linsang. It operates in embedded

But the linsangmysql subpackage implementing the operations has most of the

I'm trying to come up with a data structure that I can search for map

a value.
Essentially I have a map that contains lots of data and the key is the
primary identifier where most of the lookups go to. This is very quic

Of course! Thank you!
I mocked up a full working example

Any idea though how I would keep deletions in sync though?

Is there a equivalent of telldir in golang which can page reading of a

Just using filepath.walk would be inefficient for large file systems.

There is no telldir, but you can simply call the `Readdir` (or
`Readdirnames`) me
What do folks do in terms of managing/vetting dependencies and also hosting
them internally? In other language ecosystems, there are tools such as
Nexus or Artifactory that work as caching mirrors for binary dependencies.
That way, a company or a team can have a stronger control/governance on

Anyone working on this? Would seem to be a natural thing to implement in

I was looking at fixing an issue flagged by gometalinter, and realized I
didn't understand the actual behavior of defer statements. Specifically, I
was not handling the error return of a close operation.
I wrote a test program so I could understand the behavior, which led to
these two function
Perfect thank you!

This is not correct. The significant difference is one version has a named
return value, the other does not. The named return value allows you to capture
(by name) the return value a
