2What I hope to cover Brief descriptions of Open Source Software Free Software and the GNU GPLNot the kind of free that normally comes to mindFree SoftwareThe kind you were thinking about before, $$$Special focus on Google Apps for Education
3Is it difficult? Yes and No Yes – some aspects of open source require advanced knowledge of programming languages such as C+ and Perl…that saidNo – there are many programs that install on Windows and Mac just like any other programNo – most of the major projects have detailed instructions and wikis developed to support implementation
4Open Source Software OpenSource.org Any software developed under the GNU General Public License (GPL). IE: Linux, Mozilla Firefox and others to be discussed
5The GNU ProjectPrincipally sponsored by the Free Software Foundation.The GNU Project was launched in 1984 to develop a complete Unix-like operating system which is free software: the GNU system.The name “GNU” is a recursiveacronym for “GNU's Not Unix”
6The GNU GPLWhile the GNU kernel is still incomplete, the GNU General Public License is widely used for other GNU and non-GNU projectsWrite this down:Has enabled the “Open Source Community” by allowing input on projects from volunteers who contribute on all levels.
7How Open Source Projects work Sites dedicated to hosting Open Source projects like Sourceforge.net where thousands of projects are worked onSoftware distributions(versions) are available to download as source and compiled for a variety of Operating Systems. Linux, Windows, Mac OS X and Unix
8How Open Source Projects work Programmers test and tweak the software, uploading changes or patches to the code to the developers website.The developers take the modifications along with others and incorporate them into their next distribution, or build.Some software apps have daily or weekly builds depending on how many resources they have
9Web 2.0 AppsThe Web as a platform – Blogs, Wikis, Social Networking, Video SharingRequires that websites (front end) interconnect to live databases (back end) that can then record and display data.The Tools – Apache, PHP, MySQL, and phpMyAdmin.
10Currently in use at District 13 These three packages require a web server that runs Apache, PHP and MySQL. All are open source and free and are found on hundreds of web hosts.Moodle – “Blackboard” type web based course management system -Wordpress – Blog and website tool for teachers’ websites. Host it yourself or wordpress.net will do it for free.Joomla – Website Content Management system for our school newspaper. -
11Apache- Apache Web Server runs 65% of the world’s web servers.Cross PlatformNot exactly an Open Source model – a “meritocracy”The Apache Group(95’ish), later the Apache Software Foundation (ASF) 1999.
12MySQL- The DatabaseIt holds the data.Kind of boring.
13PHP- One of many scripting languages, including Perl, Java, Python, Ruby and more.Can be embedded into html.Connects the html to the databasephpMyAdmin – the tool to administer the database
14Building Your Own Web Server A computer – PC or MacOperating System – Windows 2000 or XP, Mac OS X or LinuxApacheHost HTML websites – use NVUAdd PHP and MySQL for more capabilitiesHighly recommend a hardware firewall
15NVUNVU – Pronounced N-View is a full fledged WYSIWYG html editor with FTP capabilities.
16Moodle Course Management system that requires Apache, PHP and MySQL. Can be used for one teacher or an entire university.Extremely well resourced Open Source Community, Lots of documentation, not too easy to get setup
17Wordpress www.wordpress.org Another extremely well supported applicationVery easy to get setup.Lots of free plugins and themesFree hosting from wordpress.net
18Joomla and Drupal www.joomla.org and www.drupal.org Extremely powerful content management systemsVery flexibleNot as easy to get setupLots of free and commercial add-ons.
