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.

Choosing an open source product or platform upon which to build an ICT4D service is hard. Creating a sustainable, volunteer-driven open source project is even harder. There is a proliferation of open source tools in the world, but the messaging used to describe a given project does not always line up with the underlying technology. For example, the project may make claims about modularity or pluggability that, upon further investigation, prove to be exaggerations at best. Similarly, managers of ICT4D projects may be attracted to Open Source because of the promise of a “free” product, but as we’ve learned through trial and error at Caktus, it’s not always less costly to adapt an existing open source project than it would be to engineer a quality system from the ground up.

This past Tuesday we held our very first gathering for the new Durham Women in Tech (D-WiT) Meetup group. There was a huge turnout and a lot of enthusiasm for the community we’re seeking to support and build. It was particularly wonderful to see our recently opened Astro Code School space full of people.

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.

We’re pleased to officially announce the launch of a new meetup: Durham Women in Tech (DWiT). Through group discussions, lectures, panels, and social gatherings, we hope to provide a safe space for women in small and medium-sized Durham tech firms to share challenges, ideas, and solutions. We especially want to support women on the business side in roles such as operations, marketing, business development, finance, and project management.

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.

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

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.

After PyCon 2015, we were surprised when we realized how many Cakti who attended had all been asked about Django’s class-based views (CBVs). We talked about why this might be, and this is a summary of what we came up with.
