[ILUG-BOM] Fw: [Fsf-friends] Free software.. and software patents (on a CD)
by Nagarjuna G. 20 Jul '03

Trevor, this CD can also be part of the library. Can you get in touch with Suraj and arrange for doenloading. Nagarjuna ---------- Forwarded Message ----------- From: "Frederick Noronha (FN)" <fred(a)bytesforall.org> To: fsf-friends(a)gnu.org.in Sent: Fri, 27 Jun 2003 14:53:25 +0530 (IST) Subject: [Fsf-friends] Free software.. and software patents (on a CD) --__--__-- Message: 9 Date: Fri, 27 Jun 2003 11:23:13 +0530 From: Suraj Kumar <suraj(a)symonds.net> To: ilugc <ilugc(a)aero.iitm.ernet.in> Subject: [Ilugc] Free Software speeches on CD I had the opportunity to download all the speeches on 'free software' and 'software patents' from gnu.org. I have cut a CD out of it. Unfortunately this collection does not contain RMS's speech at Chennai (Madras Institute of Technology) made on March 13th, 2002. However its worth noting that most of the speeches carry the same message (the only differences being the humour that he adds to various speeches). Especially the ones titled 'Free Software Movement' have little or no differences. For more information on the list of speeches, please visit: http://www.gnu.org/philosophy/audio/audio.html The CD also bundles two of GnuPress published books: 1. Free Software, Free Society - http://www.gnu.org/doc/book13.html 2. Free as in Freedom - http://www.oreilly.com/openbook/freedom/ Also included are the web pages from http://gnu.org/philosophy/ and http://gnu.org/licenses/ Interested people can borrow the CD, copy the OGGs onto your disk AND/OR make a CD out of it. All this upon the condition that my CD be returned in a day OR two. (ideally, borrow on a saturday and return on sunday). glitches: I should have put the ogg vorbis decoder (vorbis-tools and ogg123), ogg vorbis plugin for xmms, too in the CD. Maybe someone can come up with an upgraded version of the same CD with windows interop in mind, that would be fantastic! On another note, I have three empty CD-Rs. I would be very much helped if someone can make three gratis copies of the same for my own personal circulation. -Suraj -- +--------------------------------------------<suraj(a)symonds.net>---+ | The chemise lace on the buxom breasts of this belle | | is like the face shield on a rutting tusker | | (love that beauty darts - 7), Thirukkural | +---<http://symonds.net/~suraj/>-----------------------------------+ --__--__-- _______________________________________________ ilugc mailing list ilugc(a)aero.iitm.ernet.in http://www.aero.iitm.ernet.in/mailman/listinfo/ilugc -- ------------------------------------------------------------------------- Frederick Noronha (FN) | http://www.fredericknoronha.net Freelance Journalist | http://www.bytesforall.org http://goalinks.pitas.com | http://joingoanet.shorturl.com http://linuxinindia.pitas.com | http://www.livejournal.com/users/goalinks ------------------------------------------------------------------------- T: 0091.832.2409490 or 2409783 M: 0 9822 122436 ------------------------------------------------------------------------- _______________________________________________ Fsf-friends mailing list Fsf-friends(a)mm.gnu.org.in http://mm.gnu.org.in/mailman/listinfo/fsf-friends ------- End of Forwarded Message ------- ------------------------------------------------------------------------ nagarjun at hbcse tifr res in. http://www.gnowledge.org/ I support Public Library of Science http://www.plos.org/

RMS Calls On Linux Developers To Replace BitKeeper
by vinayak_hegde＠softhome.net 20 Jul '03

20 Jul '03

Hi, Another example of 'Proprietary s/w turning the screws' An excellent example why s/w needs to be free (free as in freedom and not in price) And this time it hurts where it matters most :( (for the uninitiated Bitkeeper is used for maintaining the Linux Kernel http://www.bitmover.com/bitkeeper/Products.BK_Pro.html) check out the story on slashdot http://developers.slashdot.org/developers/03/07/19/1728240.shtml?tid=185 and read RMS's reply at lkml (Linux Kernel Mailing List) http://lkml.org/archive/2003/7/18/260/index.html Vinayak Hegde Written on my m/c was - "Will work with Windows 2000/XP/NT or better" So I installed GNU/Linux.

funded FSF-OS libraries.
by Trevor Warren 20 Jul '03

20 Jul '03

Hello Luggers, Am Experimenting with a new concept. FSF-OS Libraries. Am formulating one at my place in Andheri where i will rent out Copies of all FSF - OS distros....the big to the small for a Fixed Deposit(100/-) as a safe keeping, cause very simply i want accountability. Since i will be on travel or busy with professional issues, i am have the same kept at RenDezvous Cyber...a close associate of mine whose Cable networks i have been managing for years now. Will also have a placard put up outside his place displaying "FSF-OS library". Thinking of starting with all the major distros. And then gauge the response. Also, will have a list of these put up on the web for Students/Others to access. Any other takers for the same..??. Inputs on the same???. What say???.
