Django

Last Friday marked another ShipIt Day at Caktus, a chance for our employees to set aside client work for experimentation and personal development. It’s always a wonderful chance for our developers to test new boundaries, learn new skills and sometimes even build something entirely new in a single day.

The Stanford Social Innovation Review recently featured Caktus in “Text the Vote” in Suzie Boss’ “What’s Next: New Approaches to Social Change” column. It describes how our team of developers built the world’s first SMS voter registration system in Libya using RapidSMS.

I’ve had an interest in robotics since high school, but always thought it would be expensive and time consuming to actually do. Over the past few years, though, I’ve observed the rise of open hardware such as the Arduino and the Raspberry Pi, and modules and kits built on top of them, that make this type of project more affordable and accessible to the casual hobbyist. I was excited by Katherine’s talk because Robot Operating System (ROS) seems to do for the software side what Arduino and such do for the hardware side.

I had the opportunity to give a webcast for O’Reilly Media during which I encountered a presenter’s nightmare: a broken demo. Worse than that it was a test failure in a presentation about testing. Is there any way to salvage such an epic failure?

This past Saturday, Caktus developer Rebecca Conley taught a 4-hour introductory level workshop in Django hosted by PyLadies RDU. PyLadies RDU is the local chapter of an international mentorship group for women who love coding in Python. Their main focus is to empower women to become more active participants and leaders in the Python open-source community.

This is Caktus’ first year taking part in the Catholic Relief Service’s (CRS) Information and Communication Technologies for Development (ICT4D) conference. The theme of this year’s conference is increasing the impact of aid and development tools through innovation. We’re especially looking forward to all of the speakers from organizations like the International Rescue Committee, USAID, World Vision, and the American Red Cross. In fact, the offerings are so vast, we thought we would provide a little cheat sheet to help you find Cakti throughout this year’s conference.

Part five of six in our PyCon 2015 Must-See Series, a weekly highlight of talks our staff enjoyed at PyCon.

From Ryan Kelly’s talk I learned that it is actually possible, today, to run Python in a web browser (not something that interprets Python-like syntax and translates it into JavaScript, but an actual Python interpreter!). PyPy.js combines two technologies, PyPy (the Python interpreter written in Python) and Emscripten (an LLVM-to-JavaScript converter, typically used for getting games running in the browser), to run PyPy in the browser. This talk is a must-see for anyone who’s longed before to write client-side Python instead of JavaScript for a web app. While realistically being able to do this in production may still be a ways off, at least in part due to the multiple megabytes of JavaScript one needs to download to get it working, I enjoyed the view Ryan’s talk provided into the internals of this project. PyPy itself is always fascinating, and this talk made it even more so.

Part four of six in our PyCon 2015 Must-See Series, a weekly highlight of talks our staff enjoyed at PyCon.

My recommendation would be Catherine Bracy’s Keynote about Code for America. Cakti should be familiar with Code for America. Colin Copeland, Caktus CTO, is the founder of Code for Durham and many of us are members. Her talk made it clear how important this work is. She was funny, straight-talking, and inspirational. For a long time before I joined Caktus, I was a “hobbyist” programmer. I often had time to program, but wasn’t sure what to build or make. Code for America is a great opportunity for people to contribute to something that will benefit all of us. I have joined Code for America and hope to contribute locally soon through Code for Durham.

Last Friday everyone at Caktus set aside their regular client projects for our quarterly ShipIt Day, a chance for Caktus employees to take some time for personal development and independent projects. People work individually or in groups to flex their creativity, tackle interesting problems, or expand their personal knowledge. This quarter’s ShipIt Day saw everything from game development to Bokeh data visualization, Lego robots to superhero animation. Read more about the various projects from our Q2 2015 ShipIt Day.

Sarah Bird’s talk made me excited to try the Bokeh tutorials. The Bokeh library has very approachable methods for creating data visualizations inside of Canvas elements all via Python. No javascript necessary. Who should see this talk? Python developers who want to add a beautiful data visualization to their websites without writing any javascript. Also, Django developers who would like to use QuerySets to create data visualizations should watch the entire video, and then rewind to minute 8:50 for instructions on how to use Django QuerySets with a couple of lines of code.
