The Collaborations Workshop 2017 (CW17) was the first event I've attended by the Software Sustainability Institute. The topic this year—big data and internet of things (IoT)—didn't exactly inspire me with hope that it would be relevant to my (heavily numerical) work. I couldn't have been more wrong; it was great to gain an insight into the wider infrastructure of software development and, by moving out of my comfort zone, get a new perspective on how similar problems are solved. The keynote talks by Usman and Thomas were very interesting and I have even played around with the IoT Adafruit Feather HUZZAH we were given. The "unconference" aspects meant lots of time to chat and it was great to meet people struggling with the same problems. The hackday was rewarding, again a first for me, working together on a shared GitHub repository. We managed to put together a web visualisation tools for migrant movements and a demo.
