Hi all,
The Technology Strategy Board is running a workshop on energy efficiency
tools in Bristol on 16 January, this is a free event aimed at anyone
interested in the field:
http://www.eventbrite.co.uk/e/energy-efficient-software-tools-workshop-tick…
We'll be there with the new MAGEEC energy measurement boards (all free
hardware design of course). Designed by Simon Hollis of Bristol
University, these can sample energy usage up to 6 million times per second.
It's a chance to bring along your own hardware and instrument it, or
bring along your own software and try it on some standard boards. We'll
have some ST Discovery (ARM) boards and Arduino/Shrimp boards to use if
you'd rather not risk your own hardware.
If you can't make it on the 16th, then there is a second chance to find
out more about open source and energy efficiency, because we'll be
re-running the workshop at FOSDEM as part of the energy efficiency dev room:
https://fosdem.org/2014/
Hope to see you at one of these.
Best wishes,
Jeremy

Hello everyone.
I hope no one would be offended by this advert, but I wanted to get the
word out there, and there is a strong connection to open source hardware ;)
As some of you know, I run Boldport, where I create "beautifully functional
circuits" and maintain the Python open source PCB design software, PCBmodE.
(You may have seen some of my work at Wuthering Bytes and my OSHUG
presentations.)
I'm looking for someone to join me. The technical background isn't as
critical as our ability to work together and that the person joining
understands and is passionate about the vision for what we aim to achieve
together. If there's a right match, there is an opportunity to join at a
co-founder level. I have a somewhat generic job advert on Boldport's site:
http://www.boldport.com/work.html
Other information about the company, the work, the vision, and PCBmodE is
here:
http://boldport.comhttp://boldport.blogspot.comhttp://www.youtube.com/user/boldporthttp://bitbucket.org/boldport/pcbmode
Thanks for your attention, and I look forward to hearing from anyone who is
interested. Please forward this on to others if it's relevant to them.
All the best,
saar.
Hey,
Would anyone by chance have an AVR JTAGICE mkII and would be willing
to land it for the weekend? I have just ordered one, but it might take
a while to arrive in the post... I promis a reward!
Cheers :)

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

Hello,
Registration for the last OSHUG of 2013 is now open, and it looks like
it's going to be a fun one!

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.
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

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

Al
