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

ntfsundelete - Undeleting NTFS files

And Linux saves the day again.

My son installed an application but mistakenly he selected the data directory as the installation directory. When he realized it he decided to uninstall, but the full uninstall deleted everything from the folder. This is: the program and all his files.

The solution was very easy. I found that I had already installed the ntfsprogrs package. This package contains a pretty slick utility called ntfsundelete.

This utility allowed me to first list the files that I could recover and then recover them.

Setting up Linux on PS3 the way I like it

Here are thee instructions I followed to set up Linux on my PS3 the way I like.
These instructions are for my own benefit in case I need to do it again but they may help you setting up yours. Each section is independent (unless noted) So just go to the section that interests you

- Installing.
- Using Gnome instead of E17
- Configuring resolution on Sharp HDTV LC-32D62U
- Configuring additional software repositories
- Replacing Metacity with Openbox
- Installing Multimedia codecs
- Configuring VPN

I decided to go with Yellow Dog Linux (YDL)

Setting up Vala - Trying a new programming language

Here I am, trying to learn a new programming language. Actually it feels more like getting to know the child of an old friend. Vala is a little bit like C but in a modern way and a lot like C# without having to install a huge runtime when you just want a "Hello world"

If you want to learn more just go to http://live.gnome.org/Vala

I am using Mint. An Ubuntu derivative so these instructions reflect that.

I'll first share my odyssey and then the instructions that actually worked.

Set a static IP for WPA wireless network

1. Get the encrypted WPA wireless key
wpa_passphrase <network name> "<passphrase>"
e.g.
wpa_passphrase myNetwork "This is my passphrase"
You will get something like the following:
network={
ssid="myNetwork"
#psk="This is my passphrase"
psk=eca1d01a15186d5bea7548ba6b7fed6b032b3efd79791539ba8b8fffb1fdfa1c
}

Copy the text after psk=

2. Edit the interfaces configuration
sudo nano /etc/network/interfaces

(you can use any text editor you want)

Add the following to the file replacing
