[SLUG] May SLUG Monthly Meeting — this Friday
You can read the full version of this announcement on the Web at http://www.slug.org.au/node/100 == May SLUG Monthly Meeting == When: 18.30 - 20.30, Friday, 30 May, 2008 We start at 18:30 but we ask that people arrive 15 minutes early so we can all get into the building and start on time. Please do not arrive before 18:00, as it may hinder business activities for our host! Appropriate signage and directions will be posted on the building. Where: Atlassian[0], 173-185 Sussex Street, Sydney (corner of Sussex and Market Street) Entry is via the rear on Slip Street. There are stairs going down along the outside of building from Sussex St to near the entrance. A map of the area and directions can be found here[1]. = Talks = ** General Talk ** Zachary Zeus: Open Source Business Intelligence with Pentaho It's an all-too-common scenario: an organisation with important data scattered across a multitude of different databases, spreadsheets and other sources. If only you could co-relate, compare and visualise this information, to give you an idea of where your company is actually headed! Enter the concept of business intelligence (BI). BI has for a long time been considered to be an expensive luxury (and competitive advantage) for only the wealthiest of corporations. Given recent market consolidation, you'd be forgiven for concluding that this was set to become even more entrenched. Enter Pentaho. Pentaho offers a completely open source, open standards BI stack that is enterprise-ready and accessible to everyone. Zachary Zeus will walk you through the main components of Pentaho: * BI platform * Reporting * Ad-hoc reporting * Analysis (OLAP) * Dashboards * Data Integration (ETL) * Data mining ** In-Depth Talk ** Silvia Pfeiffer: Use of Open Source Software in Vquence Vquence is an Australian start-up that provides services around online video. Vquence has built a consumer site (currently at http://www.vquence.com/) that allows people to create video playlists from millions of videos aggregated from multiple social video sites. In addition, Vquence is currently building a new service around online video tracking and measuring. The software implemented to create these services is completely built using open source software. The Web sites are built using Ruby on Rails, AJAX, MySQL, Joomla and Apache. The crawling software is written in Java. The servers are diverse, ranging from Amazon EC2 & S3, to Xen virtual servers and some dedicated servers — all running Ubuntu Linux. This talk will explain open source software used to run the business, and to develop the services. I will address the decisions behind choosing the diverse software packages and how they all work together. It will also explain the advantages and disadvantages of using open source software in such a commercial environment where high scalability and reliability are required. = Meeting Schedule = See here[2] for an explanation of the segments. * 18:15 : Open Doors * 18:30 : Announcements, News, Introductions * 18:45 : General Talk (see above) * 19:30 : Intermission * 19:45 : Split into two groups for * In-depth Talk (see above) * SLUGlets: Linux Q&A and other miscellany * 20:30 : Dinner Dinner is at Golden Harbour Restaurant, in Chinatown. We will be having the $24 Banquet[3], but we will be collecting $25 per head for ease of accounting and to cover a tip. We will be taking numbers during the break to confirm the reservation size. If you have any particular dietary requirements (e.g. vegetarian), or if you would prefer to order separately, let us know beforehand. Dinner is a great way to socialise and learn in a relaxed atmosphere :) We hope to see you there!

What I was trying to establish was two stuff: I have a pair of bunny-ears above my table. The signal is crappy. SD and HD are perfect except for a stutter say once per hour. So ... 1) Does anybody get reasonable ad detection ? 2) If they do (and I don't) then it's probably the antenna I've used lots of backends from repos and from building from 0.14 to 0.21-fixes CPUs from Celeron 1700 thru the dual core AMDs. Everything-else (but antenna) is eliminated. Even recorded simultainously on differant TV cards and compared recordings.

Digital TV is much more susceptible to impulse noise -- crappy motor scooters and the like driving past will destroy your reception. On analogue this shows up as a momentary white dot somewhere in the image. On digital, at the right point in the stream, it can wipe out the whole thing for a few seconds as it tries to re-sync. Best thing you can do is replace all the coax and splitters with quad-shielded Belden RG6. http://www.jaycar.com.au/productView.asp?ID=WB2009&CATID=22&keywords=&SPECIAL=&form=CAT&ProdCodeOnly=&Keyword1=&Keyword2=&pageNumber=&priceMin=&priceMax=&SUBCATID=415 Instead of the old-style connectors (Belling-Lee), use F-connectors (including for any splitters) all the way until your receiver, when you'll need an adapter. F-connectors are impedence matched, unlike the old style ones. http://en.wikipedia.org/wiki/F_connector This is the cheapest thing you can do and it works in most cases. You can do it yourself too if you're handy with a ladder. There's a bunch of sites about wiring up the connectors online. It's pretty easy. -- Rev Simon Rumble <[EMAIL PROTECTED]> www.rumble.net The Tourist Engineer Because nerds travel too. http://engineer.openguides.org/ In politics the middle way is none at all. - John Adams -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html

RE: [SLUG] Ubuntu drive designations (Re: update to Hardy)
In addition to the comments from Mary about partition UUID's I think you will find the reason that drives are re-designated as hdxx when adding SATA to the mix is a BIOS thing. I'm sure you will find a section in your BIOS setup that controls SATA/PATA emulation modes.

Ideally the system should be using drive UUIDs to identify partitions now rather than the dsXX and hdXX identifiers although I think in some circumstances one might not be able to. Does /etc/fstab look like this: UUID=b6c863a3-f68c-4b7f-a7b7-07e19d671903 /home ext3 defaults,errors=remount-ro 0 1 or like this:' /dev/sda3 /home ext3 defaults,errors=remount-ro 0 1 Does /boot/grub/menu.1st have a line like this: kopt=root=UUID=b6c863a3-f68c-4b7f-a7b7-07e19d671903 resume=UUID=0d6f4ee5-c312-42b1-a543-5f0f9f040eff ro or does it use /dev/[hs]dXX? (Or do you not use grub?) The idea of the UUID= identifiers for partitions rather than the dsXX and hdXX identifiers is that they should only change after a reformat, not when the kernel the way it addresses them. You can find out a partition's UUID with the "vol_id -u [partition]" command, eg: $ sudo vol_id -u /dev/sda3 b6c863a3-f68c-4b7f-a7b7-07e19d671903 There is more info at https://help.ubuntu.com/community/UsingUUID -Mary -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html
[SLUG] Problem with an upgrade to Hardy.
Just recently I upgraded from Feisty to Hardy Heron. It was suggested that I do this in two stages: first to Gutsy Gibbon and thence to Hardy. I'd upgraded to Gutsy before, but had been so cheesed off with the problems that I returned to Feisty. It may have been a grade behind Gutsy, but at least it worked. The first jump, to Gutsy, was completed and I noticed a problem that I encountered before with Gutsy. I use a docking station and whilst the background filled the Samsung monitor, the rest of the Desktop was the same size as the laptop's monitor. I assumed that this would probably be one of the problems fixed with the move to Hardy and resolutely pressed onward. The upgrade to Hardy was completed. The monitor problem had changed: now there is no picture whatsoever on the Samsung and it is indicating that nothing is emanating from the docking station. So what's gone wrong? I'd appreciate any advice. Regards, Bill Bennett. -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html
