Measuring user satisfaction with rolling NPS

Incorporate NPS surveys into your project to have maximum insight

January 10, 2016

tl;dr Our latest project (django-nps) allows you to run continuous, rolling NPS surveys, and to segment NPS by any user attribute.


NPS (Net Promoter Score) is a well-known methodology for capturing user 'satisfaction' with your product. I won't go into the details here - there's a wealth of info elsewhere on . . .

Keeping track of Django project dependencies

Introducing django-package-monitor

November 26, 2015

tl;dr We’ve released django-package-monitor, a django app to make it easier to see which packages are out of date.

UPDATE: I messed up the setup.py dependencies in the original package, and the latest package depends on a source install of semantic_version, so you will need to use the --process-dependency-links option when installing . . .

Unexpected UUIDField upset

That moment when you realise your Universally Unique Identifier... isn't.

Django, Whitenoise, and Heroku

September 16, 2015

tl;dr Heroku’s filesystem is ephemeral, so be careful when running the collectstatic command - it doesn’t necessarily do what you think it does..

Our current production asset delivery setup looks like this:

  1. Run grunt locally to generate static files
  2. Commit changes to repo
  3. Push to Heroku

Generating MoM, YoY and CMGR from SQL

Does anyone round here know SQL any more?

August 25, 2015

We recently hired someone to help us with some data analysis and reporting requirements. We're not really big enough to claim that what we needed was a Data Scientist, but that is effectively what we were looking for. And as is our wont, we created a simple test for applicants, designed to show some ability to extract meaning from data . . .

Continuous delivery at YunoJuno

BitBucket to Codeship to Heroku

June 22, 2015

Disclaimer: I'm a Continuous Deployment sceptic. I've always been suspicious of people who automatically deploy code to their live environment, and still am. Seems risky to me. See this article for more details on the difference between continuous delivery and deployment.

I've blogged before about our deployment tools, . . .
