If you're making any project of sufficient complexity, you'll need a publish/subscribe server to process events. This article will introduce you to Postgres, explain the alternatives, and walk you through an example use case of pub/sub and its solution.

Staticcheck is a static analysis tool for Go code. It has various checks, such as a check for unused variables, a check for deferring the Lock method on a mutex right after locking (the user probably meant to defer Unlock instead), a check for unreachable code, and more.

In this post we'll show sample code for which staticcheck returns errors, and how to fix the affected code.

I was recently reading Martin Tournoij's Curl to shell isn't so bad (via), which argues that the commonly suggested approach of using 'curl example.com/install.sh | sh' is not the security hazard that it's often made out to be. Although it may surprise people to hear this, I actually agree with the article's core argument. If you're going to download and use source code (with its autoconfigure script and 'make install' and so on) or even pre-build binaries, you're already extending quite a lot of trust to the software's authors. However, I still don't think you should install things with curl to shell. There are two reasons not to, one a general system management one and one a pragmatic one about what people do in these scripts.
