[SLUG] beginners home networking question
Hello everyone, I'm having a problem with the wired Ethernet connection that I've set up between my laptop and my desktop. I like to ssh into my desktop from my old laptop when I need resource heavy program like OpenOffice.org. The problem is, that if I stop working for a few minutes, the ethernet connection times out. It seems that the only way I can get my connection back is to unplug and replug the cross-over cable. Here are some details, I hope you can point me in the right direction. I'm using Ubuntu Lucid. My desktop Hostname: Antec NetworkManager: removed Firewall: Firestarter. Allows ssh connections from my laptop. Dhcp server (Because that's the only way I could get NetworkManager on my laptop to accept a connection from it) I've changed these two lines in /etc/dhpc3/dhpcd.conf: My laptop Hostname: Thinkpad NetworkManager: Yes Firewall: Firestarter.

[SLUG] OpenStreetMap
ACS South Coast Chapter In conjunction with Surveying and Spatial Sciences Institute (NSW) (SSSi NSW) and Illawarra Geospatial Users Group (iGUG) Tuesday, 31st August, 2010 Topic: A web 2.0, crowd sourcing, social networking development, OpenStreetMap (http://www.openstreetmap.org) is a rapidly growing global project to create a complete map of the world, providing free, rich geographic data to anyone for any use. The project was started because most maps you may think of as free actually have legal or technical restrictions on their use, holding back people from using them in creative, productive, or unexpected ways. Since 2004 OpenStreetMap has grown to cover the world. With good data coverage in most major urban areas of the world, OpenStreetMap provides a viable alternative to proprietary mapping data, encouraging the development of innovative software. While some of the current OpenStreetMap data has come from government and commercial imports, much of the work that goes into making the best maps comes from the contributions of individual mappers - people like you. Included within the presentation is an outline of the many ways that you can join in to help, from taking brief notes while you walk the dog, to the most efficient way to map your whole suburb and the best equipment for doing so.

Included within the presentation will be an outline of the many ways that you can join in to help, from taking brief notes while you walk the dog, to the most efficient way to map your whole suburb and the best equipment for doing so. About the Presenter: Cameron Dawdy is an active contributing member of the openstreetmap.org group since September 2008. Initially starting out as a hobby, it's developed into an excuse to visit odd places via 100km detours, as well as somewhat more practical reasons for using detailed and customised openstreetmap data for work purposes. He's got a few funny stories of travels, some gems about what openstreetmap has managed to accomplish so far, and many other aspects of openstreetmap - it's not just a map on the internet! Venue: Auditorium City of Wollongong Tennis Club Foleys Road Gwynneville, NSW 2500 Date: Tuesday, 31st August, 2010 Time: 5:45pm for 6pm – 7:30pm Meeting adjorn to Club Dining Room to continue discussion Online Registration: http://www.acs.org.au/nsw Fee:Free (Please register for this event, using the link above) signature.asc Description: OpenPGP digital signature -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html

Snake charming via Test Driven Development: Test-driven development (TDD) is a software development process that relies on the repetition of a very short development cycle: first the developer writes a failing automated test case that defines a desired improvement or new function, then produces code to pass that test and finally refactors the new code to acceptable standards.. Vaughan Allan: VP Software Engineering at Platform46 Pty Ltd. Founder: Thinkers Garden A prominent interest in languages and patterns, web frameworks, cluster computing and functional programming. A big fan of AppEngine and all things Google. Specialties: Java, Perl, Python/Django, C/C++, ColdFusion, Javascript/XML/AJAX/DHTML, Groovy/Grails, Erlang, Distributed Systems... Further Details: We will also have slots for 5 minute lightning talks. If you think its interesting and you're a pythonista then chances are we will to. Put together a few slides and bring it along. *RSVP: Please RSVP on Anyvite to get your name on the door* via http://anyvite.com/o8ro0kdjqi Getting There: It's a 10min walk from Town Hall station over the pyrmont bridge (directionshttp://tinyurl.com/nedz98) or catch the light rail to the casino station.
