Open Source Economics
Articles
- Excellent interview with Jonathan Schwartz about Suns motivation regarding Open Source: http://blogs.cnet.com/8301-13505_1-9757417-16.html%5D
- An article on Open Source economics: http://badtux.org/home/eric/editorial/economics.php
- Another article on Open Source economics by Bruce Perens: http://perens.com/Articles/Economic.html
- The Economic Motivation of Open Source Software: Stakeholder Perspectives
- Ganesh Prasad: Open Source-onomics: Examining some pseudo-economic arguments about Open Source
- Joel on Software: Strategy Letter V
- The FSF on selling free software: http://www.gnu.org/philosophy/selling.html
Business Models
Some business models identified by me:
- Marketing instrument (brand awareness, capabilities).
- Enabler for other products (server software, hardware, solutions, consulting, service, support, books).
- Free only for consumers, commercials need to pay.
Notes
- "pthread_exit" and its relationship to process termination ...
- "atexit" actually gets called by the last thread in a process
- "pthread_exit" in "main" would actually be perfect, if it was allowing to pass another return value than zero ...
- /Building OOo
- Broken __attribute__((constructor)) for gcc 3.3
- "exit" libc API call is racy wrt to pthreads on some Systems, see User:Kr/exit_race.c
My Efforts
Packaging
- Quite interesting, something I have awaited for long: ThirdPartyApt and its little brother apturl .
Effort/Revise OOo Multi-Threading
- Tasks
- review documentation, place tests and testers
- rename Environment.pReserved -> pEnterable
- do threading tests - with component, with the office
- convert rest of office services to be thread unsafe - in progress
- convert dtrans to thread affine?
- Rename Threading Model impl to Threading Framework?
- See if I can optimize the "identity mapping" somehow.
- Possible order of integration
- in progress : VCL thread-transparency 1 - vclthreadtransparency1 - depends: bunoexttm
- fix thread-affinity
- DDE
- Drag&Drop
- Clipboard
- open : Binary Uno new threading architecture - bunonewta - depends: bunoexttm
- in progress : async dialogs 2 - asyncdialogs2 - depends: asyncdialogs
- open : VCL thread-transparency 2 - vclthreadtransparency2 - depends: asyncdialogs2, vclthreadtransparency1
- remove the Solar Mutex
- open : new OOo threading architecture - ooonewta - depends: bunoexttm, vclthreadtransparency2
- in progress : VCL thread-transparency 1 - vclthreadtransparency1 - depends: bunoexttm
Move Uno stuff into the Uno Wiki. See Uno/Effort/Migrate Documentation
- Update udk.openoffice.org to reflect latest wiki changes.
Do a source code inventory
Some Links
Event Driven Programming
- Some comments regarding Linux kevents etc.: http://lwn.net/Articles/225714/ Note: In my understanding the whole discussion is senseless, the way to go for awaiting events should certainly not be fd related, but should just use something as "sigwait" or similar. Please see also Architecture/Proposal/Advanced_Threading-Architecture.
