The “Positive SSL” certificate I bought along with my domain is invalid with any of my subdomains and cannot be used with wildcards. One annoying thing is that namecheap doesn’t offer auto installation of free let’s encrypt certificates, even though, they are saying “Namecheap is dedicated to data security and privacy for all internet users. We believe the movement to encrypt nearly all web traffic is a positive direction. As more sites embrace HTTPS and use of security products, providers of free SSL are beginning to come online.”

Let me show you what it needs to be done in order to “encrypt nearly all web traffic”.

First, not required but it’s helpful to enable ssh access, it is not enabled by default on the base hosting plans, just go an start a live chat and request ssh access.

INTRO

Concurrency is a domain I have wanted to explore for a long time because the locks and the race conditions have always intimidated me. I recall somebody suggesting concurrency patterns in golang because they said "you share the data and not the variables".

Amused by that, I searched for "concurrency in golang" and bumped into this awesome slide by Rob Pike: https://talks.golang.org/2012/waza.slide#1 which does a great job of explaining channels, concurrency patterns and a mini-architecture of load-balancer (also explains the above one-liner).

Let's dig in:
