Get Ubuntu 9.04 Jaunty Jackalope Now
So Ubuntu has released 9.04 as an RC and you’re waiting for launch day to get it. Bad idea. If you’re planning on upgrading to the latest and greatest Ubuntu 9.04. I recommend doing it now. When it’s officially launched, there’s no telling when you’ll be able to get your hands on it because of the server load. Here’s how.
Hit “Alt + F2″ and type “update-manager -d”
Want more? Sorry. That’s all I got.
Unable to Lock Download Directory When Updating Ubtunu
Sometimes when you’re trying to either use the Update manager or sudo apt-get update in Ubuntu, it will throw an error saying it was ‘Unable to lock download directory’. More than likely another instance of apt-get is running in the background. Luckily this issue is easily fixed by typing this into a terminal:
sudo pkill apt
This will look for apt to see if any instances are running and kill them. Now you should be able to update as you would normally.
Using Pandora’s Windows Vista Gadget
I recently bought a new computer that is running Windows Vista. My Ubuntu computer is still my main machine, but when I need to do some serious design work, CS2 running in Wine just can’t compete with CS4 running natively on a quad-core machine with 8 Gigs of RAM.
I also love listening to Pandora. It gets turned on the second my computer boots, and turned off only when I’m away from my machine or going to leave for the day. I’ve used Pandora’s AIR app since the first day it came out (and before then I used another desktop app who’s name escapes me currently) and I absolutely love it. Even more so now that AIR has hit Linux with an official release that I can use on Ubuntu and has been rock solid so far.
While listening today, I saw that Pandora had an official gadget for Windows Vista so I thought I’d give it a shot.
Make Ubuntu Instantly More Useful
Because of it’s open source nature, some really useful but proprietary software is not included in a default Ubuntu install. Some of them include Java, Flash, Microsoft Fonts, DVD playback, etc. Luckily there’s a quick fix to install most of the things you’ll need to get up and running quickly.
Here’s how
- Go to ‘Applications’ –> ‘Add/Remove’
- Next you’ll see a drop down that says ‘Canonical-maintained applications’. Change this to ‘All available applications’
- Now type ‘Ubuntu restricted extras’ in the search box and check the result that says ‘Ubuntu restricted extras’
- Now just click ‘Apply’ in the lower right and let it download everything. When it’s installing, you’ll have to check the box that says you agree to the Java EULA, but other than that, everything will take care of itself.
Speak & Spell In Ubuntu?
Turns out Ubuntu has a seriously weird built in text-to-speech function available right in the terminal. It unfortunately sounds strikingly similar to Speak & Spell…just in case you weren’t around during the glory days of Speak & Spell (*ahem*), you seriously have to check this out first.
Now that you know why there is a generation of people who ‘can’t speak good’, I’m going to show you how to make Ubuntu talk.
- Open a terminal and type
espeak "Luke, I am your father" - Just make sure you type ‘espeak’ and then follow that with a string of text in quotes (don’t forget to wrap it in quotes)
More Options
Espeak can do some other really cool things including saving to a WAV file and speaking in different voices. Here’s how.
Save as a WAV file
- Enter:
espeak -w luke.wav "Luke, I am your father"
Monitor Your Laptops Power Consumption With Ubuntu
Found a really cool and very useful command today to monitor your Ubuntu laptop’s power consumption. Simply type the following command into your terminal.
gnome-power-statistics
If your hardware supports it, you should be presented with a screen that looks similar to the following
It’s interesting to play around with this to see how different things affect your laptops power. I turned the brightness down on my laptop from 100% to about 50% and the drop was dramatic. There are also different graphs you can view like charge history of your current session.
