Hello All, Here is some more information from Greg's note at last Friday's presentation. I'd also like to thank Greg for volunteering to talk and for such a well presented and technical topic. Seeing the data miner in action was also a bonus. Attached is the email that Greg sent to Bruce and myself earlier this week. It seems as though there is plenty more reading on the topic. I've also loaded Greg's presentation to google docs so that those that weren't at the meeting can appreciate the presentation. <quote> Hi Chris, Bruce, as discussed here's the slideshow and talk-notes from last night I promised I'd send to you to forward on to relevant people, (group-wide bounced me on the email size limit).

Re: [wlug] Nautilus slowing down...
by Sandy 27 Dec '11

I figured out the problem. I found out last night that one shouldn't temporarily store stuff in the Templates folder, because it Nautilus then thinks everything in it is a document template. I moved the contents to another folder, and now performance is back to normal. Sandy

Razor-Qt: A New Qt-Based Desktop Environment
by Peter Reutemann 23 Dec '11

23 Dec '11

Feel like a change of desktop? Just came across the following posting on phoronix: Razor-Qt is a new Qt-based desktop environment for Linux systems. The Razor-Qt desktop was just updated to version 0.4.0 after being in development for months. This release improves stability of the lightweight desktop, introduces several new components, offers new translations, a new theme, new panel plug-ins, and much more. The new Razor desktop components are azor-runner, razor-config, qtxdg, and Razor own menu. Razor-Qt is self-described as "an advanced, easy-to-use, and fast desktop environment based on Qt technologies. It has been tailored for users who value simplicity, speed, and intuitive interface. Unlike desktop environments, Razor-qt also works fine with weak machines." More information on this new desktop release can be found in this blog posting: http://yarpen.cz/rants/?p=43 Phoronix post: http://www.phoronix.com/scan.php?page=news_item&px=MTAyOTg Razor-Qt homepage: http://razor-qt.org/ Cheers, Peter -- Peter Reutemann, Dept. of Computer Science, University of Waikato, NZ http://www.cs.waikato.ac.nz/~fracpete/ Ph. +64 (7) 858-5174

how to nfs export with file system acls
by Gregory Machin 12 Dec '11

12 Dec '11

Hi. I have a "CentOS release 5.3 (Final)" server that I need to replace. I need to migrate this server to a newer platform. It is currently exporting a xfs file system with facl's , and these work well with both new and old client machines. I have tried to replicated this on Ubuntu and , discovered that I need nfs v3 and facls support compiled into the kernel, I believe that RHEL6 / CentOS 6 should have this support, but I'm still not seeing the correct results. The client doesn't have the facls , and when writing files over the export the default facls are not correctly propagated. What have I missed in the configuration ? Thanks GM -- - TLA - three letter acronym ... - We are loosing the art of communication through progress..

Creating Your Own Distributable Ubuntu DVD
by Peter Reutemann 02 Dec '11

02 Dec '11

Just came across the following HOWTO: "This article is about how to create a DVD image of the Ubuntu distribution on your machine with the exact same software included on the disk. This can be done using a software called Remastersys. ..." http://www.howtoforge.com/creating-your-own-distributable-ubuntu-dvd Might try that with my new LinuxMint installation, generating a DVD image that contains all my preferred developer tools. :-) Cheers, Peter -- Peter Reutemann, Dept. of Computer Science, University of Waikato, NZ http://www.cs.waikato.ac.nz/~fracpete/ Ph. +64 (7) 858-5174
