Openoffice and Linux Openoffice and Linux Presentation Transcript

  • HOW TO SAVE UP A LOT OF MONEY O. Teytaud Ive been informed yesterday afternoon,that I have 3 hours teaching around open source today. After all it is good news: there are not so many things in my slides, so we have time. Please interrupt me each time something is unclear.
  • HOW TO SAVE UP A LOT OF MONEY O. Teytaud 1. Introduction2. The economical model of open source 3. Open source software 4. Open source is not only for software 5. Open source & management 6. Open source & money 7. Open source & me
  • HOW TO SAVE UP A LOT OF MONEY O. TeytaudI. INTRODUCTION: GNU/Linux & openOffice
  • HOW TO SAVE UP A LOT OF MONEY O. Teytaud Stop using Microsoft Word. Stop using Microsof Excel. Stop using Microsoft PowerPoint. Download OpenOffice or LibreOffice. It is free. It works very well.Remark: it works under Windows or under Linux.
  • HOW TO SAVE UP A LOT OF MONEY O. Teytaud You like OpenOffice ? One step forward: install Linux! E.g. Ubuntu Gnu/Linux
  • Why installing Gnu/Linux ? Installation is easy. You save up plenty of money. You want new softwares ?1) Launch to the packet Manager2) Look for the software you want3) Ask for installation ==> everything automatic!Modern Linux distributions are stable.
  • Can we trust Gnu/Linux ?Well done license ==> you will never have any license trouble.Used by many administrations in the world ==> only the first time is difficult (and not very)Most supercomputers, most web servers, manymobile phones use Linux kernels and GNU tools.Your internet gateway at home isprobably under Linux.A problem ? Just “google” your problem: many userforums, the solution is usually there.
  • II. The economical models of open source
  • “Open source” does not mean “free”; yet open source code is often free. Source code needs efforts and money. But duplicating it as very low cost. Marginal cost is (almost) zero.This makes source code special (as well as books, musics, videos...). ==> New economical models ?
  • “Open source” means that the user can modify, understand the product.How can you earn money if you make the source available ?- But you can sell the product anyway (compiled, with packaging and documentation and/or maintenance)- Or you can sell the documentation.- Or you can sell the specialization.
  • What is the advantage of making your code free and/or open source?- feedback from many users- free help for debugging- free new features- free documentation by forums- no copyright enforcement cost (lawyers or engineers for security are expensive)- developers are happy, because their work helps many people
  • III. Open Source software
  • Some important open-source software: Plenty of things under Gnu/Linux. - GCC (Gnu C/C++ Compiler) - YACC - Firefox - Linux Kernel (used everywhere)- GIMP (free equivalent of Photoshop) - Android (derived from Linux) - FreeBSD <== highly stable Unix- Eclipse (development environment) - Apache: HTTP Web Server - MediaWiki (code for Wikipedia) ==> also: open-source hardware
  • IV. Open Sourceis not only for software
  • OPEN SOURCE IS NOT ONLY FOR COMPUTER SOURCES: LifeTrac is a low-cost, multipurpose open source tractor. It serves as a workhorse backbone for many of GVCS technologies. Prototype III stage has been completed, and field testing determined the need for Prototype IV prior to product release. Featuring a modular design and detachable PowerCube units, it has the ability to rapidly switch between a variety of GVCS machines via the QA Plate. The machine is overbuilt with a focus on lifetime design and ease of repair. Four hydraulic motors provide skid steer power to the wheels, and a chain tread system enables navigation of extreme terrain.

  • THESE SLIDES ARE OPEN SOURCE I made them publicly available for other teachers. Someone made Interesting comments. A few weeks ago,I used (and acknowledged it) slides from Marian Such who published his slides. Wikipedia is free documentation (seemingly weak in Chinese ?).
  • OpenMoKo: Open Source mobile phone. Open-Cola: Open Source Cola.
  • V. Management & Open SourceIn many domains:Professional life is unjust.You can not compete with someone who has moneyenough for building an entire company.With software its different.With Open Source its very different.
  • Management & Open SourceStarting from nothing but a computerand an internet connection, you can developa great open source software, or become a greatcontributor of an existing open source project.No entrance fee: just be the best and youllfind a position in open source.Sure, this does not provide money:- use advertisements;- call for donations;- sell side services (e.g. studies).
  • Management & Open Source Who do you trust, for an important project ?- the guys who developed a successful open source project;- the boss of a corporate which develops a proprietary code that people only buy because they have compatibility issues ?
  • Management & Open Source Who do you trust, for A geek who loves his an important project ? lob and wants it to be known worldwide- the guys who developed a successful open source project;- the boss of a corporate which develops A guy with plenty a proprietary code that people only buy of meetings with lawyers. because they have compatibility issues ?
  • Management & Open Source: competitionOpen-source is a two-sided sword:- you develop at low cost (free help, no security cost);- but you give to other people the possibility of competing (e.g.: they know your file formats).An open source project which is not very efficientis dead.Someone else will develop a better version.Whereas close-source projects can survivejust because of compatibility.
  • Management & Open SourceYou want to hire a great person ?Hire a developer of a great open source project!You want to be hired ?Show your knowledge by becoming the maincontributor of a domain in Wikipedia, or a keycontributor to an open source project.
  • VI. Open source & moneyThe key problem for open source is money.Open Source also works by public fundings.Because mainly Open Source developers areacademics, or students with public funding.In my humble opinion, its a good use of publicmoney.
  • Open source & moneyGlobal licenses ?It is sometimes proposed (for music or video)that internet users pay a global tax which isused for funding developments, proportionallyto the number of users.Advertisement ?With advertisement, you can get money quicklyjust with your webpage or your source code.
  • VII. Open source & meI still lose a lot of time in intellectual propertymeetings, because so many people are afraidof open source.I would be more useful, if I couldspend this time writing in Wikipedia or GNU code.I think this is the case for MANY people.The cost of intellectual property is HUGE.
  • GIVE IT A TRY !
  • Change your life! Try open source. Choose a software in the list (a few slides above), which might be helpful for you, and give it a try. ((Youre very strong ?Find a missing feature (see the wishlist on the web site). Implement it yourself. You get no money, just fame, and pleasure of helping people.))
