Uniquely Managing Test Execution Resources using WebSockets

Executing tests for simple applications is complicated. You have to think about the users, how they interact with it, how those interactions propagate through different components, as well as how to handle error situations gracefully. But things get even more complicated when you start looking at more extensive systems, like those with multiple external dependencies.

Dependencies come in various forms, including third-party modules, cloud services, compute resources, networks, and others.

This level of complexity is standard in almost all projects involving a large organization, whether delivering internal tools or external products.

It means you must put emphasis on developing test systems and mechanisms good enough to validate not just code, but those third-party dependencies as well. After all, they’re part of the final product and failing to interact with them, means the product fails.

PyCaribbean 2018 - Sofi Unity3d Lightning Talk

2018-02-22 python pycaribbean sofi gui 3d async

PyCaribbean 2018 lightning talk where I demo sofi-unity3d from a live Python interpreter. The talk starts at 18:43 and shows how to spawn, manipulate and animate objects in 3d space using Unity3D.

Making 3D Interfaces for Python with Unity3D

2017-05-19 python 3d packaging sofi async Cristian Medina

A while back I wrote a post on using with game engines as frontend interfaces. I want to enable rich interfaces in the Python ecosystem that are usable in virtual and augmented reality. Since then, I was able to build some basic concepts on top of Sofi and I’m here to share them.

Using Sofi and WebSockets to command game engines

Sofi works as a WebSocket server that can issue commands and handle events from a client. It’s written to simplify the use of frontend web technologies as interfaces to a Python backend. You can even package it as a desktop app with a desktop look and feel.

It functions by sending the user to a webpage with the basics needed to open a WebSocket client. This client then registers handlers that process server commands telling it how to alter the DOM or respond to events. All the logic resides with Python, the webpage is the user interface.

Musings of a dev trying to plan for the future

I remember making a program come alive back in the days of the IBM System 23. It was my first endeavor into programming. I must have been 7 years old and already using terminals for data entry to help my dad out in his business. I wrote code that highlighted items on the screen in different shades. For the younger me, it was an achievement to be proud of, even though color was not yet available in these monitors.

Fast forward a few decades — yes, only a few — and we’re in a completely different universe. One where 3D gaming with thousands of people at the same time is possible. A space that collides with realistic physics, represented by lifelike graphics and beautiful scenery.

While a gigantic leap from the olden days of monochrome monitors and ASCII graphics. From a human’s perspective, there’s still a layer of separation between reality and the digital world. But we’re about ready to break through that barrier.

A Python Ate My GUI - Part 3: Implementation

2016-08-15 python gui sofi async Cristian Medina

Time to Bootstrap your D3, pick up that Python and hop on the Autobahn

If you aren’t aware of my earlier posts, check out Part 1 and Part 2 of this series so that you get some context for this ongoing exercise.

Since I started thinking about and working on these posts, I’ve also been developing the ideas on GitHub as a side project I called sofi.

Sofi is a Python 3 package that serves as the starter implementation of the design discussed in Part 2: a system that will generate the necessary HTML and JavaScript code typically needed to produce a single-page application and serve it up through WebSockets (not an HTTP server).

A Python Ate My GUI - Part 2: Design

2016-07-12 python gui sofi Cristian Medina

In the first part of this series, we discussed a few existing modules that give us tools for building interfaces. I promised to come back with some ideas on how I would attempt to solve the situation, and this post is intended to cover aspects of my initial design.

However, first I need to discuss one more point on existing modules. In case you’re not aware, PyCon 2016 happened a few wks ago in Portland, and amongst the many wonderful talks, keynotes and open spaces, there was one in particular that is relevant to the topic of our discussion here: Russell Keith Magee’s talk on BeeWare and the work he’s done to solve the same problem. I highly recommend you take a look and help out with his projects if you can. It’s definitely a bold and brave solution that’s highly complex, but he already has it at a usable state and deserves massive props for going down that path. The Podcast.__init__ guys also have a great interview with him going over the details.

Sofi - An OS agnostic UI module for Python.

2016-02-16 python gui sofi async open source Cristian Medina

Built to allow rapid, pythonic GUI development using standard web-based widgets from Bootstrap and other common HTML5 libraries and package them in such a way that all event processing is done within python using websockets.
