The optics family of #haskell packages make it possible to define and use Lenses, Traversals, Prisms and other optics, using an abstract interface. They are roughly comparable in functionality with the lens package, but explore a different part of the design space: https://github.com/well-typed/optics

If you are a system administrator, or just a regular #linux user, there is a very high chance that you worked with #syslog, at least one time.

On your Linux system, pretty much everything related to system logging is linked to the Syslog protocol.

Designed in the early 80’s by Eric Allman (from Berkeley University), the syslog protocol is a specification that defines a standard for message logging on any system.

Syslog is not tied to Linux operating systems, it can also be used on Windows instances, or ony operating system that implements the syslog protocol.

If you want to know more about syslog and about Linux logging in general, this is probably the tutorial that you should read.

Presently, real-time communication tools such as Slack are very popular in business environments. However, use of these tools creates a culture that harms projects. It negatively impacts planning accuracy, implementation quality, product refinements, and design quality. I will tell you about the many issues created by real-time messaging in workplaces, and how to remedy your work culture.

Functional architecture tends to fall into a pit of success that looks a lot like Ports and Adapters.

In object-oriented architecture, we often struggle towards the ideal of the Ports and Adapters architecture, although we often call it something else: layered architecture, onion architecture, hexagonal architecture, and so on. The goal is to decouple the business logic from technical implementation details, so that we can vary each independently.

This creates value because it enables us to manoeuvre nimbly, responding to changes in business or technology.

Purely functional code makes some things easier to understand: because values don't change, you can call functions and know that only their return value matters—they don't change anything outside themselves. But this makes many real-world applications difficult: how do you write to a database, or to the screen?

In this screencast we look at one method for crossing this divide.
