To turn our Docker transmogrification into a platform, we need to go from running a single job to running hundreds of thousands. That’s an engineering problem with a name: Orchestration.
Great article on how orchestrators work, and why Fly.io wrote their own.
In this post I’ll attempt the fun stunt of designing a system that could serve the full production load of Twitter with most of the features intact on a single (very powerful) machine. I’ll start by showing off a Rust prototype of the core tweet distribution data structure handling 35x full load by fitting the hot set in RAM and parallelizing with atomics, and then do math around how modern high-performance storage and networking might let you serve a close-to-fully-featured Twitter on one machine.
Fun!
I see people making the same mistake with tools like Kubernetes. Many, if not most stacks, simply don’t need it… and those that do pay the price for all the overhead and brittleness.
Amazon has published an Amazon Web Services SDK for Go programming language. Currently it’s experimental, so expect bugs, but you can already use it to manage your AWS stuff.
When you purchase an SSL certificate from a certificate authority, in most cases it is signed not by the root certificate of this authority, but by an intermediate certificate(s). The path from your certificate through those intermediates and up to the root is called a certificate chain. While browsers can resolve those chains by downloading certificates from sources specified in them, the whole chain except for the root cert is better to be included in the response your server sends during TLS connection.
Forget scripto-Perlo-C porridge to setup a web interface for Git! Forget installing thousands of dependencies to setup your own repository hosting! Gogs is here to make your life easier!
Gogs is a GitHub clone written in Go, which you can host on your own server. It’s a web interface to Git repositories plus a simple bug tracker. Gogs is very easy to install and use.
