Karmic Koala and sound on the HP DV6105us

I attended the Karmic Koala release party at the kwartzlab and had the opportunity to upgrade my laptop from the local repository.

Everything went well except for the sound on the laptop. Thankfully the alphas, betas and RC periods are for people to find these issues and provide workarounds :D.

My card is identified by lspci as

00:10.1 Audio device: nVidia Corporation MCP51 High Definition Audio (rev a2)

The problems were:
- Sound didn't work
- Sound made a crackling sound.

Showing your OpenOffice Impress presentations online

I've been using Impress for some time to create presentations but I used to upload them as odp files when I wanted to share them with the world (in case the world came to see them).

That is, until I "discovered" that exporting them to flash was a piece of cake.

  1. Open your presentation in Impress
  2. From the main menu select "File | Export"
  3. On the Export window select "Macromedia Flash (SWF)"

After that all that's left is

Upload the presentation to a website or file sharing site and reference it from a web page using the following HTML code:

Software Freedom Day

Yesterday I was fortunate to participate in the Software Freedom Day organized by the working centre in Kitchener.

There I had the opportunity to give three presentations.

I'm posting them here in case anyone is interested in looking at them, modifying or using them at other events.

What are we celebrating
In this presentation I walked through some of the current rights and freedoms regarding digital content. The ones we currently have and give for granted as well as some of the existing artificial barriers to enjoy those rights.

Submission to copyright consultation

The deadline to make a submission to the Canadian Copyright consultations is September 13.
Richard pointed out a guide with astroturfing instructions: http://faircopy.ca/participate/.

This is the main consultation site: http://copyright.econsultation.ca/

This is my uninformed, blathering submission. It is less well-informed than an article published in the Waterloo Record. If I can make a submission, so can you!

Streetposts

After much research and investigation, I have started in earnest on my streetposts project. I think I'm going to use net beans. I started to make a database today in OpenOfficeBase. I setup the structure of all of the tables according to google's specification, and set the primary keys. I made all of the tables using the names supplied by the google transit api.

Living Well Using Open Source

Are you sick of cleaning viruses and spyware off your computer? Are you tired of nagware, time-limited trials, and sketchy download sites with lots of pop-up ads?

Would you like to use software in a way that suits your needs and avoids treating you like a criminal?

Does the cost of computing deter you from developing new skills and exploring new interests on the computer?

Improving XOrg pefromance for Intel video under Ubuntu 9.04 (Jaunty Jackalope)

When I upgraded from Linux Mint version 6 "Felicia" which is based on Ubuntu 8.10 to version 7 "Gloria" based on Ubuntu 9.04 my video performance started suffering badly. Worst of all, I couldn't watch videos using any of the applications installed vlc, miro, gmplayer, mythTV, Totem.

To see the kind of errors I was getting refer to my bug report

What worked for me was reverting the Jaunty Xorg intel driver to 2.4 as explained in this link

Undeleting FAT Files

I already had a post on undeleting files from an NTFS partition. But what if the partition is a FAT partition? Don't worry there are several solutions that will only require you to use a handful of commands.

IMPORTANT: Do not write anything or use the partition where the delete file is. That will increase your chances of getting your files back

I've used a couple of solutions. Both successfully but geared to two different situations:

The fist method is is PhotoRec
