Dirk used the LTSP workstation and the KLUG SVGA projector to display his slides with OpenOffice.org Impress. He presented two SAMBA file management implementations. The first was Microsoft’s DFS that allows file shares on Windows workstations. The second was Rsync that allows you to back up one machine’s files to another machine.
Distributed File System (DFS) allows administrators to group shared folders located on different servers by transparently connecting them to one or more DFS namespaces. A DFS namespace is a virtual view of shared folders in an organization. Using the DFS tools, an administrator selects which shared folders to present in the namespace, designs the hierarchy in which those folders appear, and determines the names that the shared folders show in the namespace. When a user views the namespace, the folders appear to reside on a single, high-capacity hard disk. Users can navigate the folders in the namespace without needing to know the server names or shared folders hosting the data. DFS also provides many other benefits, including fault tolerance and load-sharing capabilities, making it ideal for all types of organizations.
Dirk showed us how to sync one Linux box to another. Updating only the files that have changed to protect from data loss. He gave us three suggestions to avoid problems. #1) Does not copy ACL’s. Create a file with getfacl to recreate the acl’s if you have problems. #2) Use Logical Volume Management (LVM) to create a snapshot of what you are backing up. #3) Use ssh transfer method. a BASH shell script was given that performs these three tasks from the CLI.
Next we saw how to connect a Windows box to a Linux box for file system archiving using cygwin.. cygwin allows you to run Linux applications on a Windows box. The opposite of wine, which allows Windows applications to run on Linux. Dirk gave the BASH shell scripts that accomplishes the tasks listed below automating the procedures from the CLI.
How to Get Windows Files Synchronizing to Linux: #1) Install cygwin. http://www.cygwin.com/ ß more about cygwin here #2) Get ssh working. [see ssh presntation] #3) Script your way to Rsync bliss.
Inkscape is an Open Source vector drawing tool with capabilities similar to Adobe Illustrator, Macromedia Freehand, and CorelDraw that uses the W3C standard scalable vector graphics format (SVG). When you consider that Adobe Illustrator costs over $450, that the proprietary source code is not user modifiable, and that no personal support is available from developers... Inkscape shines brightly. Direct end-user software support from Inkscape developers is possible. The production program is FREE! Kevin displayed a slide presentation and a live demonstration of Inkscape stable release 0.41 that is intended for current production use. http://www.inkscape.org/
We heard about the WC3 SVG standard and how the math of the Bezier curve is fundamental. A statement was made by one of the observers that, "What vector graphics do for images is like what Postscript did for text." In the demonstration we saw how to use various tools including the primary "Pen Tool." You could hear frequent exclamations including 'wow' and 'nice' from the presentation attendees. Learn more about the WC3 spec. SVG is a language for describing two-dimensional graphics and graphical applications in XML. http://www.w3.org/Graphics/SVG/
GPL’d desktop publishing Scribus, image-editing GIMP , and vector graphics Inkscapes combine to give Open Source and Linux a powerful suite of applications that are improving every day through collaboration. http://www.scribus.org.uk/ http://www.gimp.org/
Almost everyone knows how the TV quiz show Jeopardy is played. Hasn’t it been a very successful edutainment format TV game show?
Back in October of 2001, on Halloween, KLUG members gathered in Dunbar Hall on the WMU campus for what was being billed then as Open Source Jeopardy. Adam Williams used a classroom chalkboard to list the answers and KLUG's Brian Ritz was the scorekeeper. Adam had the questions written on cards which were sorted by points and categories. Adam transferred that info to an entire wall of chalkboards. That was a bunch of writing and the manual score keeping was rather difficult. In following years, the name was changed to Geek Jeopardy and Adam put all the information into a spreadsheet application. That sure beat all that writing.
In anticipation of celebrating the 5th year of the annual festivities, KLUG Linkmaster (KLUGware too) Jon Smitley put Open Source tools together with the game process to create an application with a graphical user interface for the display of the categories, points, and answers. It even handles the game scoring. Wheel of Fortune's Vanna White was apparently unwilling to perform the scoring duties for us. It does include an MC display that provides the correct questions. Even Alex Trebek could handle this application. He also had the buzzer system working just like it was expected to. There are Jeopardy, Double Jeopardy, and even Final Jeopardy sessions included.
Jon calls the application "AMPardy." The Merv Griffin attorneys vigorously protect their intellectual property so care was taken to not be taunt copyright actions. AMP stands for the Apache web server, the MySQL database, and the widely-used general-purpose scripting language that is especially suited for web development and can be embedded into HTML… PHP! Were any problems encountered? Only minor ones and that is why all software is beta tested.
Jon, with some help, did an excellent job of putting together this AMP application. You can be sure it will be ready for Halloween 2005 and the annual KLUG Geek Jeopardy party. There was some uncertainty about whether or not this application could be released as Open Source code without running into legal problems. We’ll find out more about that in the future.
The test topics included Geek Cinema, CPU Architectures, YRO, Redmond, LDAP, Samba, X11, Slang, XML, CLI, "Things that spin", and "RFC Potpurri" that were snagged from a previous year’s spreadsheet archive file. The software testing session was enjoyed by a raucous crowd of previous year Geek Jeopardy enthusiasts. No one had more fun than the originator, Adam. He got his first chance to show how much he knows and how good his memory was from back in October of 2002. Adam did blow the rest of the teams out of the water but you could tell that he was not the only player with quick fingers and a good knowledge of the Open Source technology and community.
It was 90 degrees, wonderfully humid, and partly sunny tonight. To our surprise, 14 people attended the monthly General Assistance (& Install) Meeting. Chair John Bridleman launched into the abbreviated introduction and made quick conclusion. Snacks where abundant, the basement WAP was working, The were no install assistance requests this month. Is it so easy now that nobody needs help with installs? Well, that is great… KLUG is ready if anyone does want help.
While many Linux related discussions were spawning around the room, a desktop box with a long forgotten BIOS password was cleared employing the motherboard jumper technique. Several solutions were offered by the group. Access to the BIOS was needed to get the box to boot off the DVD/CD for an install at a latter date.
Brock and Leola got help from Dirk, Bob, and Andrew. They had their 64-bit Compaq (HP) laptop their for some assistance. Leola wanted printing help and found out how she could get the output she wanted. The printing of a #10 envelope was an accomplishment. Leola also had lessons in burning a CD-ROM. She took root to avoid problems.
