The Erlang Runtime System

For anyone who: Want to tune an Erlang installation. Want to know how to debug VM crashes. Want to improve performance of Erlang applications. Want to understand how Erlang really works. Want to learn how to build your own runtime environment.

If you want to debug the VM If you want to extend the VM If you want to do performance tweaking—​jump to the last chapter … but to really understand that chapter you need to read the book.

CoreDNS is a DNS server/forwarder, written in Go, that chains plugins. Each plugin performs a (DNS) function.

CoreDNS is a Cloud Native Computing Foundation graduated project.

CoreDNS is a fast and flexible DNS server. The key word here is flexible: with CoreDNS you are able to do what you want with your DNS data by utilizing plugins. If some functionality is not provided out of the box you can add it by writing a plugin.

CoreDNS can listen for DNS requests coming in over UDP/TCP (go'old DNS), TLS (RFC 7858), also called DoT, DNS over HTTP/2 - DoH - (RFC 8484) and gRPC (not a standard).

Python libraries to make your code readable, reliable and maintainable

Experienced programmers understand perfectly well that in development they spend most of the time reading code and therefore they treat the process of writing code with the deepest trepidation (and sometimes with fanaticism). To write quality and maintainable code, you need to take the time to write tests and integrate QA tools. There is a whole technique aimed at test-driven development (TDD) and I will not devote this article to the topic of testing as such. Tests are absolutely necessary and there is nothing to discuss. In this article, we are going to talk about tools that help you write quality Python code.

6 Awesome Ways To Present Your Code

At some point, every developer has to present code snippets. This could be for a presentation, or a tweet, or a blog, or just to go through a snippet later in time.

Let's dive into the tools you can use to present your code awesomely.
