The Philosophy behind Open Source

Chief Open Source Officer

Topology of society has changed from Hub & Spoke to Mesh

Structure of society has changed and the Internet is turning society into a participation mesh

Consumers becoming participants (theyworkforyou.com)

Software Developement

• Closed Room
• Open Room
• Open source is software developement in a participation society – connected capitalism.

Virtuous cycle of open source

• Freedom to create derived works
• Anyone can check code out
• Few can check it back in

Software 3.0

• Software mashups
• Debian Ubuntu with OpenSolaris kernel – provides dtrace and ZFS to Ubuntu

Licences

• CDDL for OpenSolaris
• GPL for Java

Riches if

• Collaborate
• Compete
• Contribute

Open Source will be dominent by the end of the decade !

Sun OpenSolaris London Tech Days 07 (Day 3) [Summary]

It was a mixed bag at today's Sun Tech Day

"The Zen of Free" (part 1.5 !) by Simon Phipps, Chief Open Source Officer, Sun inc, who is always worth watching even if he is saying the same thing !

"VMware" hadn't been told NOT to do a marketing presentation and deservedly got heckled ! In the "good old days" VMware would have been booed off stage !

"jMaki & AJAX hands on lab" 10 out of 10 ! I will actually try NetBeans now !

LUNCH

"AMD" I think everyone was just there to win the prize draw for a Solaris Workstation !
 
"Future of Java: Open Source Projects and Communities" Interesting but I'm already a believer !

"Mobile J2ME drag drop app building with NetBeans" OK ! OK ! I get the point ! I will try NetBeans !

Sun OpenSolaris London Tech Days 07 (Day 1) [Summary]

Todays Sun Tech Day was an inspirational and motivating as ever

The Zen of Free by Simon Phipps (impressive yet again) (he's already blogged his morning in London)

• Open Source is Topology of Society
• Closed Source is a closed room with none of the smart people
• Open Source is an open room with all of the smart people
• not giving back is bad for you
• no-one has ever forked Apache
• Open Source gives customer choice of what to spend their money on : service, support, staff or risk it !
• 26% of Debian has been written by Sun (9% by IBM 5% by RedHat)
• As well as OpenOffice.org Sun also contibute to Gnome and Mozilla (i18n)

Collaborate, Compete & Contribute

OpenSolaris Kernel Debugging
Kicked off to a great start when the audience was asked "Does anyone here actually do any kernel debugging" and of course none of us did ! Sound advice included "If you don't understand this (patching opcodes in memory) then don't do it". And topped off with "I never did figure out why the system failed at midnight – but a fix is a fix".

Building and Deploying OpenSolaris
Did you know

• 2000 users in Poland have registered on OpenSolaris.org
• There are already 7 distros based on OpenSolaris
• Nexenta distro uses GNU Debian packages and Ubuntu apps
• Schillx is a live CD distro

We want you to contribute easiest to start with a bite sized bug that you are interested in

OpenSolaris Virtualisation Technologies
OpenSolaris supports

• XEN with guests on ZFS
• Zones 

CentOS 3 or Red Hat RHEL 3 can run using a Solaris kernel instead of Linux (so you can use dtrace etc etc)

New Security Features in OpenSolaris
Trusted Extensions

• Similar to SE linux (in my view)
• Processes and resources have labels
• Uses Zones
• Can prevent cut & paste between Gnome windows with different security levels (SE linux doesn't do this)
