There are a lot of videos available from this years Linux Foundation Collaboration Summit.

The videos are more focused on the development tactics and the strategies of vendors to promote gnu/linux.
But nevertheless interesting.

Just two examples

About Elves and Alf’s

May 25, 2008

After watching the edition Eco-Defense or Eco Terrorism? of stimulator’s It’s the end of the world as we know it and i feel fine show I informed myself more about the ELF and ALF.

The Earth Liberation Front (ELF), also known as “Elves” or “The Elves“,[1] is the collective name for anonymous and autonomous individuals or cells who, according to the now defunct ELF Press Office, use “economic sabotage and guerrilla warfare to stop the exploitation and destruction of the environment“,[2] commonly known as ecotage or monkeywrenching. [wikipedia]

While I think that non-violent actions, informing of people and mobilizing them should be the way to change the thinking of people and the rescuing of animals/environment, I think the ELF/ALF also make a point with distinguishing violence against things and violence against living creatures (human and non-human).

I found two films about the ELF and ELF available online. Both are kind of “propaganda” or better.. films which explain their ideology and actions.

A film about the ALF is available on google video.

The other one about the ELF is available as a torrent download.

At last the guidelines of ELF which summarizes their ideology

  • To inflict maximum economic damage on those profiting from the destruction and exploitation of the environment (biophysical).
  • To reveal to, and to educate the public about the atrocities committed against the earth and all species that populate it.
  • To take all necessary precautions against harming any animal – human and non-human.


Green your life…

May 23, 2008 is a new website that aims to create an easily accessible database of simple ways to make your everyday choices more environmentally friendly. This is accomplished through a listing of broad categories – appliances, personal care, clothing, etc. – with a variety of sub-categories – air-conditioning, face wash, shoes, etc. – that contain professional ‘green’ tips. All the tips are licensed under a CC BY-NC-SA license and users are encouraged to contribute comments, feedback, and even their own tips to the site’s database.


Tapestry for Nonbelievers

May 20, 2008 has an article explaining the benefits of using apache tapestry as an webframework for your projects.

In this article we are going to introduce you the version 5 of the framework. We will develop a simple Create/Read/Update/Delete application using Tapestry 5 and show a few of the productivity benefits provided by Tapestry.
We will describe different aspects of Tapestry applications, such as page navigation, dependency and resource injection, user input validation and application state management. You will also see how to use the Ajax functionality built in to Tapestry and how to create your own Ajax-capable components.


Why should I care about OSGi

May 19, 2008

Adrian Colyer talks about OSGi and what benefits comes with using it.

Development time benefits

  • Strict development time (and runtime) enforcement of module boundaries
  • A service-oriented architecture that works for managing service dependencies between modules.
  • Better ability to structure development teams the way you want to
  • Faster team-based development
  • Faster testing cycles
  • Support for versioning as part of dependency management

Runtime benefits

  • Full information about the installed modules and their wiring is available at runtime – a level of insight operations teams have never had before
  • Isolate changes
  • Share dependencies
  • Use just the server facilities you need

All this assumptions are backed up with arguments in his article.

Asking big questions about the universe

May 17, 2008

Who could be better suited for answer some of the big questions of the universe than Stephen Hawkings.

Fascinating watching how he communicates.

Hague declaration for free and open standards

May 16, 2008

We call on all governments to:
1. Procure only information technology that implements free and open standards;
2. Deliver e-government services based exclusively on free and open standards;
3. Use only free and open digital standards in their own activities.

This is what The Digital Standards Organization ( demands. The reasons why they are demanding this is

  • Government information, services and resources are increasingly provided virtually rather than physically
  • Freedom of speech and association are increasingly exercised on line rather than in person
  • The Internet and the Web provide an unprecedented avenue to equality of education and opportunity for all peoples throughout the world

You can support them by signing their petition.


The falling of the OLPC

May 15, 2008

Ivan Krstiic a former programmer in the OLPC project explains his side of the problems OLPC is facing and why he thinks that the project is doomed to fail.

Peru’s first deployment module consisted of 40 thousand laptops, to be deployed in about 570 schools across jungles, mountains, plains, and with total variance in electrical availability and uniformly no existing network infrastructure. A number of the target schools are in places requiring multiple modes of transportation to reach, and that are so remote that they’re not even serviced by the postal service.
Laptop delivery was going to be performed by untrusted vendors who are in a position to steal the machines en masse. There is no easy way to collect manifests of what actually got delivered, where, and to whom. It’s not clear how to establish a procedure for dealing with malfunctioning units, or those dead on arrival.
Compared to dealing with this, the technical work I do is vacation.

Despite my disagreements with his view on Free Software (he thinks that Richard Stallman is kind of a lunatic), despite this, I find his report quite interesting and a good read to get more insight in a project of this scale.


Nazis on the moon

May 14, 2008

The creators of Star Wreck are making a new film called Iron Sky. Why this is good news? The producers are a group of Finnish techies who distributed Star Wreck for free over the internet.

While this is great, it is getting better. The new film will be released under a Creative Commons license which ensures everybody can watch the film for free.


The race to idle

May 13, 2008

Modern CPUs are great. They have all sorts of advanced power saving features, which is one of those nice cases where everyone can save money, gain performance and claim environmental credentials at the same time. Everyone’s a winner.

Well. Everyone’s a winner as long as your software doesn’t suck.

Matthew Garret talks about the current state of power saving abilities of modern CPU’s and how software is trying everything to make things worse.

Some people write software that lets you choose different power profiles depending on whether you’re on AC or battery. Typically, one of the choices lets you reduce the speed of your processor when you’re on battery. This is bad. It is wrong.
The people who implement these programs are dangerous. Do not listen to them. Do not endorse their product and/or newsletter. Do not allow your eldest child to engage in conjugal acts with them.
Failure to do so will result in me setting you on fire[4].
