2009-01-22 Green Computing
Thursday January 22 2009, NLUUG will organise an event with the theme
Green Computing. Lectures will be held in Dutch and English.
There will be presentations on the subject of Green Computing. Some
of the topics that are addressed are:
- Reversible computing / Adiabatic logic
- Low power wireless networks
- Lessons from the embedded space
- Developments in hardware
We have found a rather special location for this environmentally
vision of the future, namely "Het
Paradijs in Enschede". This space is best described as an indoor
garden that was built from reused material with the creative zeal to
make something of unique beauty. We could not have wished for a more
suitable place to organise this NLUUG-day, given its green theme.
Nicolaas Beetsstraat 48,
7514 CW Enschede,
The entrance is FREE (as in free beer).
The event is supported by Syntens.
To assure yourself of a place, please register by sending an email to
email@example.com, including your name and (if applicable)
organisation. You will receive a reminder by email just before the

Innoveren, kan dat goedkoper?|
Carlos Silva dos Santos (Syntens)
Innovatie is het toverwoord op dit moment. Innoveren betekent werkzaamheden op
een andere of nieuwe manier doen. Innoveren betekent ook nieuwe producten en/of
diensten ontwikkelen. Overheden bedenken veel instrumenten om innovatie te
stimuleren. ICT-bedrijven actief in het open source software domein zijn
eigenlijk per definitie innoverend. Van welke instrumenten kunnen
ICT-bedrijven, actief in het open source software domein gebruik maken? Carlos
Silva dos Santos van Syntens zal kort maar krachtig antwoord en toelichting
geven op bovenstaande vraag.
Carlos Silva dos Santos, is innovatieadviseur en projectleider van het
programma OASE. Hij is werkzaam bij Syntens, innovatienetwerk voor ondernemers,
een initiatief van het Ministerie van Economische Zaken. Zijn passie is samen
met MKB-ondernemers werken aan strategische concepten waarbij ICT in het
algemeen en open source software in het bijzonder worden ingezet.
An energy-efficient call|
dr. ir. Lodewijk Smit
Under the hood, complex technology is required to make a simple
mobile UMTS phone call possible. Energy efficiency is often
associated with low power hardware. This is not the complete
story. In the software stack a lot of global cross-layer
optimizations are possible at run-time, which may result in
substantial energy savings.
Lodewijk Smit is co-founder of Recore Systems. He received a PhD
in the area of energy-efficient wireless communications. In
2005/2006 he was visiting researcher at Lucent Bell Labs in Murray
Hills, NJ, USA.
Small hardware saves you a lot|
Small hardware can save you and everybody a lot of time, energy and
headaches. These days, people tend to buy bigger, faster and mostly
better. But better doesn't necesarely mean bigger. However smaller
doesn't imply that either. This lecture will give you some insights in
how to choose the right hardware for the right job and how you can help
the environment, your energy bill and your power connectors from being
overtaken by the hardware which is available these days.
Mendel Mobach is a fulltime geek for Systemhouse Mobach BV.
and involved in a couple community projects like NLLGG, CCC events
and HAR2009, CACert server administration and a lot more.
Adiabatic electronics design|
Rick van Rein (GroenGemak)
Electronic circuits are wasteful, and can be viewed as a collander through
which power gradually leaks away. Adiabatic design of electronics, even if
it is very difficult to apply in practice in the short run, is intruiging
because it approaches the logic port at the electronic level, and uses clever
tricks to evade, rather than reduce the consumption of power.
Dr.ir. Rick van Rein is a trained computer scientist as well as an
electronics engineer. Adiabatics are interesting for his work at
GroenGemak, where he works for computers and electronics with strongly
diminished power usage patterns.
Legal limits to reverse engineering.|
mr. drs. Walter van Holst (Mitopics)
The vast majority of energy expended on computing is spent during
production of the semiconductor chips and not so much during its
actual use. Therefore green computing also means extending the use
of legacy hardware beyond the lifetime of the OS drivers available
for such hardware. Especially in the FOSS-world of BSD and Linux,
reverse engineering legacy hardware drivers in order to allow hardware
to interoperate with more modern operating systems is not unheard
of. This presentation is about the limits copyright law imposes on such
Walter van Holst is by day a legal consultant at Mitopics and as such
is involved in IT-contracts and conflicts. He has a background in IT as
well as in law.
Save valuable battery life with
Linux power management|
Aschwin Marsman (MontaVista)
In this presentation power management fundamentals will be
discussed and how you can design for power management in a Linux
environment. A five step guide will be shown which can be used when
designing for power management.
Aschwin Marsman is working with Linux since 1993 and with UNIX since
1990. He is working as a software engineer in technical environments:
wafer steppers, cancer treatment, air traffic control, self checkout
systems etc. He started aYniK Software Solutions in 2001 and is currently
working for MontaVista as the solutions architect for the Benelux &
How green is this OLPC's XO?|
Talking about the environment is not only talking about consuming power.
In this presentation we are going to look at the ecological footprint of
this laptop, and resources used in the factory and production.
At the end of the 90's an growing interest emerged in computer
networking and free software. In 2000 he migrated an office environment
to Debian GNU/Linux for a cultural center. Marten organized several
linux install parties in 2001.
Marten is co-founder of Wireless Leiden (2002) a city wide
wireless community network. Since 2006 he is chairman of the WifiSoft.org foundation. Besides their
main activity the OpenCommunityCamp other activities take place like
BSDmonthly, Optic Networking and the Network Event Kit.
Marten works parttime as unix and network administrator for the University
of Leiden. In his sparetime Marten is mostly active in his repairing
center for OLPC en the Network Event Kit.
