Programming BLE the hard way: bare metal programming of nRF51 BLE tokens for fun and profit

Bluetooth Low EnergyThe talk will start with a brief overview of the Bluetooth Low Energy advertisement protocol and how to implement bare-metal BLE on top of the ARM-based nRF51 chip – without using the manufacturer provided Bluetooth stack. The general development flow will be explored along with some useful examples, closing with some mischief that can be caused using this knowledge.

Exploring “Open” in Energy

Hydrogen fuel cellsArcola Energy builds energy systems using fuel cells powered by hydrogen. Fuel cells are one of those great ideas that has yet to gain much traction in real markets. They put men on the moon, but since then commercial progress has been slow. One way of opening up uses of fuel cells is to involve a much wider developer community. To explore this Arcola has developed a fuel cell developer kit and started on the road to working with Open Source groups. This talk will look at our journey, the success to far and the challenges ahead.

Richard Kemp-Harper is a former research scientist who spent several years managing web development, including Open Source systems at Oxfam. He then moved into technology and innovation, working at Innovate UK running innovation programmes in intelligent mobility, rail and energy. He specialises in not being a specialist.

Superoptimization: How fast can your code go

Speaker: James Pallister, University of Bristol

Super TuxModern compiler optimization can take almost any code and produce a reasonably efficient binary at the end. However compiler “optimization” doesn’t make your code “optimal”, just better.

In contrast, superoptimization can produce perfect code – the fastest, the smallest or the most energy efficient code. The technique, first introduced in the late 80s found in some cases it could do 25% better than the best assembly programmer, and 40% better than the best compiler at the time.

Free software has always played a central role in superoptimization research, with the GNU Superoptimizer being one of the very first tools constructed.
