S.London Makerspace - Make Day & Meeting 7th Dec
by Tom Newsom 19 Nov '13

19 Nov '13

Hi all, I'll be brief! We're setting up a new makerspace for South London, in a railway arch at Loughborough Junction. We're getting close to getting a move-in date from Network rail, but in the mean time, we're holding a series of Make Days, in order to build our community, work on our projects, share knowledge and discuss our plans for moving forward. The next meeting is on Saturday 7th, at the London College of Communications, Elephant & Castle. If you'd like to come and meet us and have a say, we'd love to see you there! For fire safety/security reasons, registration is required, which can be done at http://www.eventbrite.co.uk/e/make-day-december-2013-registration-9420752725 If you're at all interested in what we're up to, you can find out more at our blog: http://www.southlondonmakerspace.org/ facebook: https://www.facebook.com/SouthLondonMakerspace twitter: https://twitter.com/LDN_Makerspace Cheers, Tom Newsom Trustee, South London Makerspace

OSHUG #30 — Speed (overclocking, souped-up BBC Micro, compiler optimisation), 28th November 2013.
by Andrew Back 08 Nov '13

08 Nov '13

Hello, Registration for the last OSHUG of 2013 is now open, and it looks like it's going to be a fun one! Cheers, Andrew // Event #30 — Speed (overclocking, souped-up BBC Micro, compiler optimisation) 28th November 2013, 18:00 - 20:00 at Erlang Solutions, New Loom House, 101 Back Church Lane, London, E1 1LU. Registration: http://oshug.org/event/30 The thirtieth OSHUG meeting is dedicated to the quest for computing speed. It will feature talks on a hardware design to aid overclocking, retrofitting a 30+ year old microcomputer with modern processors, and compiler optimisation. — Fast and Furious: Overclocking chips for fun and profit Due to the variance in silicon manufacturing technologies, integrated circuits used in everyday designs are usually spec'ed at lower speeds than their actual capabilities. It is, therefore, not unlikely for chips to run faster than their advertised speeds, sometimes at significant margins with a little push. The umbrella term used for this practice isoverclocking and it encapsulates a variety of techniques from simply increasing the clock speed to employing elaborate systems with liquid nitrogen cooling. This talk will provide an overview of overclocking and overvolting techniques — investigating the effects of forcing chips to run faster on the silicon level — and present vftweak: an open source hardware design that aims to simplify experimenting with circuits by providing a programmable interface and monitoring tools. Omer Kilic works on Erlang Embedded, a Knowledge Transfer Partnership project in collaboration with University of Kent and Erlang Solutions. The aim of this project is to bring the benefits of concurrent systems development using Erlang to the field of embedded systems; through investigation, analysis, software development and evaluation. Before joining Erlang Solutions, Omer was a research student in the Embedded Systems Lab at the University of Kent, working on a reconfigurable heterogeneous computing framework. Omer likes tiny computers, things that 'just work' and real beer. — Souping up the BBC Micro This talk will introduce a selection of projects which allow modern processors to be used with a 30+ year old BBC Micro, before exploring in more detail the speaker's own open hardware contribution to the options available. Jason Flynn creates open electronics designs for the amateur radio and retro computing. His main areas of interest are digital TV, microwave, satellite and most things related to Acorn and ARM. He previously held a post on the RSGB Data Communications Committee, is an honorary member of SSETI, has been committee of Martlesham Radio Society for 7 years, and is presently involved in setting up a hackspace in Ipswich. — How compiler optimisation helps you get the best out of your hardware This talk will give a high-level overview of compiler optimisation, covering general approaches used in both local and global optimisation, and also taking a look at the technique of superoptimization. The talk will conclude by looking at some of the 200+ optimisation passes used in GCC. The talk will be given by Jeremy Bennett, and he will be joined by Joern Rennecke and Simon Cook, who will take questions about optimisation in the compilers on which they are involved. Dr Jeremy Bennett is founder of Embecosm and an expert on debugging and silicon chip modeling. A former academic, Jeremy holds a MA and PhD from Cambridge University and is a Chartered Engineer, Chartered Information Technology Professional and Fellow of the Royal Society of Arts. He is the author of the standard textbook, "Introduction to Compiling Techniques" (McGraw-Hill 1990, 1996, 2003). Simon Cook leads Embecosm's work on LLVM and is author of the standard guide to the LLVM assembler. He is also an expert on low-energy compilation, being lead engineer on the MAGEEC project. Simon holds a double first class honors degree in Computer Science and Electronics from Bristol University. Jörn Rennecke is an expert on compiler back-end optimization and also leads Embecosm's work on GCC. Over 18 years he has become one of the all-time largest contributors to the compiler. During 2006-9, Jörn was a major contributor to the EU-funded MILEPOST project, which developed the first machine learning compiler optimization framework. He is currently maintainer for GCC for the Epiphany and Synopsys ARC architectures and a major contributor to GCC for Atmel AVR. Note: Please aim to arrive for 18:15 as the event will start at 18:30 prompt.

FOSDEM 2014 Energy-efficient Computing devroom
by Jeremy Bennett 30 Oct '13

30 Oct '13

Hi all, The MAGEEC project (www.mageec.org) is hosting a developer room at FOSDEM next February. We'll be exploring all aspects of energy-efficient computing using open source hardware and software. FOSDEM, the Free and Open Source Developers' European Meeting, is held annually over a weekend at the Université Libre de Bruxelles. It is free to attend and attracts over 5,000 participants. The energy-efficient computing devroom will run on Sunday 2nd February. We have a call for participation out now. You are invited to submit your proposals for taking part in the devroom. You can read more about all the devrooms on the FOSDEM website: https://fosdem.org/2014/news/2013-10-02-accepted-devrooms/ which links to more details for the energy-efficient computing devroom here: http://mageec.org/wiki/FOSDEM_2014_Energy-efficient_Computing_devroom The deadline for proposals is 25 November. Don't hesitate to contact me or Andrew Back (copied), or to post to the MAGEEC mailing list (http://mageec.org/cgi-bin/mailman/listinfo/mageec) if you have any questions or would like to know more. Best wishes, Jeremy -- Tel: +44 (1590) 610184 Cell: +44 (7970) 676050 SkypeID: jeremybennett Twitter: @jeremypbennett Email: jeremy.bennett(a)embecosm.com Web: www.embecosm.com

Xmos Startkit
by Alan Wood 18 Oct '13

18 Oct '13

Those who know me or have or have attended some of my earlier (pre TVRRUG) OSHUG talks will be aware that I frequently work with Xmos multicore micro-controllers among my many other favourite technologies. Xmos are a UK chip design company (like ARM) who are doing a lot of work to push the technology envelope and they extensively use Opensource tool chains along with their community opensource libraries at xcore ( https://github.com/xcore). They have recently made efforts to widen their product lines and lower the barrier to entry, if you are interested in exploring XS1 technology and perhaps adding to their opensource developer pool you might be interested in a special promotion they are running called Startkit where they are giving away some great simple development boards for folks that may have a good idea to try out on them. Anyhow I don't want this to appear to much like an advert but I really respect what these folks are doing and hope that this doesn't put anyone off by posting it here on OSHUG You can find the offer here: https://github.com/xcore regards Al

Open Source Hardware Summit
by Andrew Katz 16 Oct '13

16 Oct '13

You're probably all aware of this, but if not: next year's Open Source Hardware Summit is likely to be in Europe, venue TBC. If you can come up with a compelling reason why Hebden Bridge is the ideal venue (and who can't?) then now is the time to get stuck into the discussion over on lists.oshwa.org. Best Andrew
