A Tour of the Flang Fortran Compiler

Kiran Chandramohn

Flang is a Fortran compiler recently open sourced by PGI. Flang generates LLVM IR and benefits from the optimizations implemented in LLVM. It also runs on a variety of hardware. In a short span of time Flang has garnered a lot of interest. It is the frontend for PGI and Arm Fortran Compilers. In this talk I will briefly cover the history of Flang, the open source context, standards conformance, technical details, performance numbers, f18 project and the future roadmap of flang.

Kiran is a Compiler Engineer working at Arm Ltd. He is responsible for the productization of the Arm Fortran Compiler based on open source Flang project. He holds a PhD degree from the University of Edinburgh.

Mentoring & Advocacy + AGM – 25 October 2018

Whilst open source is now more widely accepted, there are still large parts of the engineering community who have yet to “see the light”.  Advocacy remains a key role for all who care about open source, while mentoring helps user make best use of open source technology.

At this evening meeting in London, we’ll be welcoming leading speakers on this topic.  This is a joint meeting with the UK Open Source Hardware Users Group and will also include the AGM of the BCS Open Source Specialist Group.  Venue is the BCS Offices at 5 Southampton St, London WC2E 7HA from 6-8pm.

Registration link: TBC

Each talk will last 30 minutes and include plenty of time for questions. We look forward to seeing you there.

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.

Fashion Technology, Stem Cell Research & Mental Health

Rachel “Konichiwakitty” Wong

Rachel will be talking about her personal projects in Fashion Technology and her work in stem cell research and how open source and social media communications has helped her achieve her goals. She will also touch on the importance of having a varied interest in relation to mental health.

Rachel “Konichiwakitty” Wong (@konichiwakitty) is a wearable tech innovator and a stem cell scientist. During the day, her PhD involves using stem cells to grow optic vesicles to study and find a cure for genetic childhood blindness. When she isn’t working, she creates wearable fashion technology. She combines her skills in sewing an jewellery-making together with programming and electronics. She exhibits and gives talks on her fashion tech projects around the world to encourage young girls into STEM education and careers. She was recently awarded a Electronics Weekly BrightSparks engineering award for her work in tissue engineering and fashion technology. She can be found on twitter as @konichiwakitty where she shares all her latest projects.

Delta Printers Are Really Cool

Bracken Dawson

A short talk on the the ups and the many downs of delta machines, when & why you should use one, what the challenges are and a few different ways to conquer those challenges.

Bracken is a developer at IBM working on the Cloud. He was one of the five founding trustees of So Make It, the Southampton makerspace. He has been building 3D printers since the 3D printing boom in 2012.

“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.
