LCA 2010 Thursday

Jeremy Allison on ‘The elephant in the room – free software and microsoft’. While he works at Google, this talk was ‘off the leash’ – not about Google :). As usual – grab theย  video ๐Ÿ™‚ We should care about Microsoft because Microsoft’s business model depends on a monopoly [the desktop]. Microsoft are very interested in ‘Open Source’ – Apache, MIT, BSD licenced software – the GPL is intolerable. Jeremy models Microsoft as a collection of warring tribes that hate each other… e.g. Word vs Excel.

The first attack was on protocols – make the protocols more complex and sophisticated. MS have done this on Kerberos, DCE/RPC, HTTP, and higher up the stack via MSIE rendering modes, ActiveX plugins, Silverlight…ย  The EU case was brought about this in the ‘Workgroup Server Market’. MS were fined 1 Billion Euros and forced to document their proprietary protocols.

OOXML showed up rampant corruption in the ISO Standards process – but it got through even though it was a battle against nearly everyone! On the good side it resulted into an investigation into MS dominance in file formats -> MS implemented ODF and MS have had to document their old formats.

MS have an ongoing battle in the world wide web – IE / Firefox, ajax applications/ silverlight.

All of these things are long term failures for MS… so what next?… Patents :(. Patents are GPL incompatible, but fine with BSD/MIT. The Tom Tom is the first direct attack using MS’s patent portfolio. This undermines all the outreach work done by the MS Open Source team – which Jeremy tells us are true believers in open source, trying to change MS from the inside. Look for MS pushing RAND patented standards: such things lock us out.

Netbooks are identified as a key point for MS to fight on – lose that and the desktop position is massively weakened.

We should:

  • Keep creating free software and content *under a copyleft license*.
  • Keep pressure on Governments and organisations to adopt open standards and investigate monopolies.
  • Lobby against software patents.
  • Search for prior art on relevant patents and destroy them.
  • Working for a corporation is a moral choice: respectfully call out MS employees.

Jonathan Oxer spoke about the google Moon X-prize and the project – it needs contributors: software and hardware hackers, arduino/beagleboard/[M]JPEG2000 geeks, code testers and reviewers, web coding, documentation, math heads & RF hackers. Sounds like fun… now to find time!

Paul McKenney did another RCU talk – and as always it was interesting… Optimisation Gone Bad (RCU in Linux 1993-2008). Linux 2.6 -rt patch made RCU much much much more complex with atomic operations, memory barriers, frequent cache misses, and since then it was slowly being whittled back, but there is now a new simpler RCU based around the concept of doing the accounting during context switches & tracking running tasks.


LCA 2010 Thursday Keynote – Glyn Moody

Glyn Moody – Hackers at the end of the world. Rebel code is now 10 years old… 50+ interviews over a year – and could be considered an archaeology now ๐Ÿ™‚ย  I probably haven’t down the keynote justice – it was excellent but high density – you should watch it online ๐Ÿ˜‰

Glyn talks about open access – various examples like the public library of science (and how the scientific magazine business made 30%-40% profit margins. The Human Genome Project & the ‘Bermuda Principles’: public submimssion of annotated sequences. In 2000 Celera were going to patent the entire human genome. Jim Kent spent 3 weeks writing a program to join together the sequenced fragments on a 100 PC 800Mhz Pentium processor.ย  This was put into the public domain on just before Celera completed their processing – and by that action Celera were prevented from patenting *us*.

Openness as a concept is increasing within the scientific community – open access to result, open data, open science (the full process). An interesting aspect to it is ‘open notebook science’ – daily writeups, not peer reviewed: ‘release early, release often’ for science.

Amazingly, Project Gutenberg started in 1971!

Glyn ties together the scientific culture (all science is open to some degree) and artistic culture (artists share and build on /reference each others work) by talking about a lag between free software and free content worlds. In 1999 Larry Lessig setup ‘Copyright’s Commons’ built around an idea of ‘counter-copyright’ – copyleft for non-code. This didn’t really fly, and Creative Commons was setup 2 years later.

Wikipedia and newer sharing concepts like twitter/facebook etc are discussed. But… what about the real world: transparency and governments, or companies? They are opening up.

However, data release !=ย  control release. And there are challenges we all need to face:

  • GFinancialC “my gain is your loss”. Very opaque system.
  • GEnvironmentalC “my gain is our loss”

Glyn argues we need a different approach to economic governance: the commons. 2009 Nobel laureate for Economic Sciences – Elinor Ostrom – work on commons and their management via user associations… which is what we do in open source!
