Fwd: Galway Linux installfest, Sat 17th Nov

Via Andrew Gallagher:

Galway LUG is organising a Linux installfest on Saturday 17th from 10am-noon in the DERI building, Lower Dangan (map). This is a chance for you to bring along your old laptop/desktop and give it new purpose in life! If you have thought about trying Linux, but haven’t yet summoned up the courage, here is your chance to get some hands-on help. We will have several experienced users on hand to help you select, install and configure your first Linux.

A word of warning: if you have data on your hard drive, please BACK IT UP before bringing your machine. Galway LUG and its volunteers cannot be held responsible for loss of data. It is your responsibility to have current backups.

See you there!

Multiple MediaWikis on Debian

Spent a few hours today trying to make a “wiki farm” on Debian using MediaWiki. I already had six wikis using separate code directories on the one server, so when I needed to update them all it was a real pain. Having to create a seventh standalone wiki today pushed me to doing this. I documented it here. Not sure if my notes will be helpful to others but I hope so… Took a little longer as I wanted to be to lock down each wiki with htpasswd (I know you can lock down parts of MoinMoin, but MediaWiki isn’t so partitionable).

Decrypting PDFs for printing, modifying

I was trying to print out some PDF files today that I had downloaded from a government website, and encountered the encrypted PDF phenomenon (I got a “This operation is not permitted” message or some such).

After much frustration, I found a site that said you can use the Ghostscript pdf2ps utility to convert the problematic PDF to a PostScript file, and then use ps2pdf to convert it back to a nice unencrypted PDF file for printing. Both pdf2ps and pdf2ps are available for GNU/Linux and Windows. GSView will also often open and print such PDFs just fine.

iPodLinux, iDoom, Videos / Unwanted Scratches on iPod nano

I was showing off my iPod nano (won at the Simile ISWC 2005 semantic bank competition) at the Cork geek bloggers’ dinner recently: just got iDoom working yesterday (thanks for the link to it Brendan!) and was watching videos on it today after installing the latest kernel from iPodLinux. The video functionality is pretty nifty (but requires large AVI files because it is uncompressed); was playing the Superman Returns teaser trailer and the latest episode of the Simpsons (very watchable).

However, I have my first iPod nano screen scratch; I popped the nano out of its protective Jelly Belly box and was less than happy to see a small mark right in the middle of the screen. Hopefully the shop will take it back (I managed to retrieve the receipt, thanks Brian!).

irishblogs.org | Irish Blogs. Organised.

Started another site for free Irish blogs, because I wanted this one to be different: I’d like to allow people to organise their posts by category (using taxonomies) or tag (using folksonomies).

I’ve started the taxonomy, which is a hybrid of Yahoo! Directory and the Open Directory Project, but I’ll add the new folksonomy module for Drupal (backported from 4.7 to 4.6) later on. I hope to enrole some taxonomy editors from the irishblogs mailing list too.

BTW there’s a good article on Drupal in this month’s Linux Magazine, and I’m happy to see that the latest release of Drupal (4.6 from last month) has PHP5 support.

Thunderbird's RSS News and Blogs Fnality

I like Thunderbird’s RSS functionality, especially the way you can forward interesting snippets from blogs to your friends via e-mail without copying from one news reader application to your mail client. I’ve only set up a few blogs and news sources in it so far but here’s a screenshot of Thunderbird’s RSS reader. There’s probably something similar in Outlook, but I haven’t used Outlook so can’t confirm…
