A look at the first implementation of GraphQL in Cylc

For Cylc 8 we are adding an initial implementation of GraphQL, to replace the previous REST API. Besides the technologies in the API’s, another difference is that for the REST API, its main consumer was a PyGTK GUI.

The new GraphQL API, on the other hand, will be used mainly by a Vue.js Web application. So a few things need to be done in a different way due to the jump from Desktop GUI to Web GUI.

PyZMQ Basics - Part 1

I am working on a project that is adopting ZeroMQ. This post series is for self understanding of PyZMQ, a ZeroMQ libzmq binding for Python.

What is ZeroMQ?

ZeroMQ (or 0MQ, or ØMQ) is an Open Source library that provides building blocks for communication in distributed applications. The communication can be between the threads of a process, between process (inter-process), or via network protocols such as TCP and UDP.

It is optimized for performance, and has been used in many applications, giving users a solid foundation to be used in their projects.

Creating a logo in Inkscape - process

This weekend I spent some computer time not writing or reading code, but actually toying around with Inkscape to create a logo. While it created using very simple operations in Inkscape, it took me quite a while to remember the shortcuts and how to merge objects.

This logo is not actually used. It was an entry to a call for proposals.

The Process

This post won’t have much text. It will be more screen shots of the process with short commentaire.

How the Skosmos Widget Wiki plugin works

Skosmos can be extended through plugins, or widgets (a widget is a plugin for Skosmos). You can read more about how plugins work in Skosmos here.

This post is a note-to-self, explaining how the Skosmos Widget Wiki plugin works. This is a plugin - or widget - that displays Wikipedia information when the concept supports it.

Here’s an image of the plugin in action. Or you can go to a live instance of Skosmos that has the plugin enabled.
