Caktus Blog

Technology Tank, a communications and tech think tank, recently ranked their top 10 stories of 2014 and Caktus made the cut. Earlier this year, we shared a story about Libya’s SMS voter registration system. We’re happy to learn that other people were just as excited about our work enfranchising Libyan voters as we are! The list is based on number of visits to the story.

With Girl Develop It RDU, we celebrated the launch of Lightweight Django (O’Reilly) with the authors, Caktus Technical Director Mark Lavin and Caktus alum Julia Elman. Sylvia Richardson of Girl Develop It MCed. The event was open to the public and so popular we kept recounting the RSVPs and fretting over the fire code. But, phew, we were good. In attendance were friends, family, fellow Cakti, and Django fans from around the Triangle.

This October, nearly everyone at Caktus took a break from their usual projects to take part in Caktus’s 8th ShipIt Day. Apart from a few diligent individuals who couldn’t afford to spare any time from urgent responsibilities, nearly everyone took a break to work and collaborate on creative and experimental projects, with the aim of trying something new and ideally seeing a project through from start to finish in the space of a day and a half.

We’ve launched NCGetCovered.org, a site dedicated to helping North Carolinians gain access to health insurance. As many know, enrolling in health insurance can feel daunting. NCGetcovered.org aims to simplify that process by centralizing enrollment information and great resources like live help. The site is launching ahead of the November 15th open enrollment period for the federal healthcare exchange (healthcare.gov).

In exciting local news, Durham and Durham County are launching a new site dedicated to centralizing public data in Summer 2015. Their press release mentions a health sanitation app Code for Durham built as a model of civic engagement with open data. Our own co-founder and CTO, Colin Copeland, is co-captain of Code for Durham, a volunteer organization dedicated to building apps that improve government transparency.

We’re honored to announce that we’ve won two W3 Silver Awards for Creative Excellence on the Web. The awards were given in recognition of our homepage redesign and DjangonCon 2014. Many thanks to Open Bastion and, by extension, the Django Software Foundation for selecting us to build the DjangoCon website. Also many thanks to our hardworking team of designers, developers and project managers that worked on these projects: Dan, Daryl, David, Michael, Rebecca, and Trevor!

Using Amazon S3 to Store your Django Site's Static and Media Files

Storing your Django site's static and media files on Amazon S3, instead of serving them yourself, can improve site performance. It frees your servers from handling static files themselves, lets you scale your servers easier by keeping media files in a common place, and is a necessary step to using Amazon CloudFront as a Content Delivery Network (CDN).

Update: The live webcast is now available at O’Reilly Media

Our technical director, Mark Lavin, will be giving a tutorial on Django and Backbone.js during a free webcast for O’Reilly Media tomorrow, November 6th, 1pm EST. There will be demos and a discussion of common stumbling blocks when building rich client apps.

(Thanks to Mark Lavin for significant contributions to this post.)

In a previous post, we introduced using Celery to schedule tasks.

In this post, we address things you might need to consider when planning how to deploy Celery in production.

I have had the good fortune of working internationally on mobile health applications due to Caktus’ focus on public health. Our public health work often uses RapidSMS, a free and open-source Django powered framework for dynamic data collection, logistics coordination and communication, leveraging basic short message service (SMS) mobile phone technology. I was able to work on two separate projects tracking data related to the 1000 days between a woman’s pregnancy and the child’s second birthday. Monitoring mothers and children during this time frame is critical as there are many factors that, when monitored properly, can decrease the mortality rates for both mother and child. Both of these projects presented interesting challenges and resulted in a number of takeaways worth further discussion.
