Hammerspoon: Staggeringly powerful macOS desktop automation

Chris Jones

Hammerspoon exposes many parts of macOS to the simple scripting language Lua. Its goal is to make the most powerful and flexible tool for serious power users to automate and customise as many things as possible. In this talk we’ll look at the history of automation on Apple computers, how Hammerspoon works, and some of the excellent things it can help you do. Of course, it’s Open Source, so you can also jump in and help make it even better!

Chris Jones has been creating, using, and advocating for Open Source software, since the mid-1990s. He’s spent the last 12 years of his professional life working on/with Open Source – the first half at Canonical (creators of Ubuntu) and since then working on OpenStack at HP and Red Hat.

After 13 years of zealously running only Linux on his desktops/laptops, he has spent the last 8 years recovering as a macOS user, but has nevertheless retained his passion for contributing to Open Source.

This talk was to have been given at our June meeting which was cancelled. We are delighted Chris is available to give his talk at this meeting.

Sous-vide cooking with a Raspberry Pi

Chris Swan

Cooking with a touch of science and a dash of engineering. Sous vide (under vacuum) is a technique that places food into a temperature controlled water bath. The vacuum bit isn’t that important, and squeezing the air out of a zip lock bag is generally sufficient; but precise temperature control is essential to ensure that the right proteins are denatured. The thermostat in a typical piece of kitchen equipment is nowhere near good enough, but add a sensor (immersible temperature gauge), an actuator (433MHz remote control socket), some control software and a dev board to run it on and you have the ability to cook perfect steaks, eggs, fish or whatever.

Chris has been tinkering with electronics since he was a small child, and got into software when he realised that it was necessary to make hardware do interesting things. In his day job as CTO for Global Delivery for DXC Technology he’s bringing a large services company and its customers into a world of DevOps and Infrastructure as Code. On evenings and weekends he can often be found making some sort of project around a dev board, with a particular fondness for Raspberry Pis.

Deploying GPG to non-technical users

Sevan Janiyan

Introducing the use of cryptography in to day to day workflow can be overwhelming for new user, not helped by concepts which can be difficult to grasp, especially for non-technical users. This talk will cover a small scale deployment of GPG which is currently in progress for a team of 30 members and how the use of GPG was implemented within an organisation.

Sevan Janiyan is founder of Venture 37, which provides system administration & consultancy services. As a fan of operating systems and computers with different CPU architectures, in his spare time he maintains builds of open source software on a variety of systems featuring PowerPC, SPARC and armv7l CPUs.

“In the future, everyone will work for 15 minutes.”

Adrian Bowyer

There is much said about the coming impact on work of the robot and AI revolutions, some of it quite well-informed. But the powers of automation and intelligence are dwarfed by the power of something else: self-replication. After the fundamental forces of physics, self-replication is the most significant phenomenon that there is. Using the Sun’s energy over the last four billion years, self-replication and Darwin’s Law have created a world-surface that is knee-deep in reproducing nano-machines. Indeed, your very knees are made out of them.

Yet engineering hasn’t worked with the power of self replication much, if at all, until now. This talk will be about the RepRap Project—an open-source project that has created humanity’s first general-purpose self-replicating manufacturing machine. It will examine the likely social and economic impacts of self-replicating technology, and draw parallels with a twelve-thousand-year-old industry that uses natural self-replicating machines, the industry without which we would all starve: farming.

Adrian Bowyer holds a first degree and a PhD in engineering from Imperial College. He was an academic engineer and mathematician at the University of Bath for 35 years, from where he retired in 2012 to become a director of RepRap Ltd., a company that sells RepRap machines and components, and that undertakes research and consultancy in RepRap-related projects. RepRap Ltd is an entirely open-source company, and all its designs, software and documentation are freely available to everyone.

His areas of research are geometric modelling and geometric computing in general (he is one of the creators of the Bowyer-Watson algorithm for Voronoi diagrams), the application of computers to manufacturing, and biomimetics. He is the author of about one hundred papers and books on many different aspects of engineering, computing, mathematics and biology.

As a collective of female musicians, artists, engineers, computer scientists and researchers, Female Laptop Orchestra has been pushing the boundaries of technology and cross-cultural co-located and distributed collaborative music making since 2014. Besides musical instruments, we use a variety of open source and commercial tools to create music, stream music and connect with our audience during the performance. We often collaborate with classical composers and ensembles, filmmakers, visual designers, choreographers and dancers. Recently, we also collaborated with members of Women in Music Technology (a student organization whose goal is to encouraging more women to join the music tech field of study and highlight the often unsung role of women in music technology, based at Georgia Tech Centre for Music Technology in US) and Sonora (a collaborative network bringing together artists and researchers interested in feminist manifestations in the context of the arts, based in Brazil).

Nela Brown is a sound artist, technologist, researcher and educator. In the past decade, she composed music and designed sound for award-winning projects including theatre performances, dance, mobile, film, documentaries and interactive installations. She is the founder of the Female Laptop Orchestra (FLO), an eclectic group of female musicians and technologists exploring co-located and distributed collaborative music making within different contexts and across different geographical locations. As a creative director of FLO since 2014, Nela co-ordinated 7 national and international FLO performances involving 36 collaborators from 21 different countries.
