Prior to the upgrade I made sure that my Karmic system and all my installed apps were as up to date as possible. Then I backed up my my installed apps with APTonCD. Fortunately, this was not needed but it gave me comfort in knowing that I had some level of recovery in case something went wrong. The upgrade proceeded without problems unlike the upgrade to Karmic that aborted and left with me with many days of cleanup work. There were a few questions about whether to keep certain configuration files that had been created by third party software. Not being certain on how to answer, I simply opted to keep them believing that I could resolve any problems at a later time.

At the start of the upgrade, Ubuntu informed me that third party repositories would be disabled. I would have to manually re-enable them after the upgrade. This is where I encountered the “bumps”. I have over a dozen third party repositories enabled. The upgrade took a little over an hour to complete. But then there remained the repository update. Simply re-enabling the repositories did not work. The authentication keys were lost in the upgrade. A little research on the Internet taught me how to regain a lost key. This added about another two hours to the upgrade.

I am not criticizing Ubuntu for this upgrade necessity. I am simply calling it to my readers attention. It is part of the upgrade process. The Synaptic Package Manager will inform you of disabled repositories. Go to the Settings tab and click on Repositories. Re-enable them one by one, editing and changing the distribution information to “lucid”. Then “reload” the repositories. It is at this point that you will encounter problems involving authentication keys, missing repositories and other problems.

Ubuntu improves a bit with each release. This release is no exception. I recommend that all Ubuntu users do the upgrade as long as their equipment permits it.

Apple names Mac OS X releases after wild jungle cats, Jaquar, Tiger, Leopard and etc. A Lynx is a genus of medium sized wild cats. If future Ubuntu releases are to be more Mac-like in look and feel then this is certainly an apprpriate release in which to make that change.

The GNOME desktop is highly customizable. If it happens that you prefer the window controls to remain on the right this click here for instructions on how to use the GNOME Configuration Editor to make that change. Alternately if you have the latest version of Ailurus installed it can make the change for you.

What this clever program does is to setup a web server on your machine. Besides the money manager, there are programs for file and photo sharing, music playing and a bittorrent client. Upon initial use you setup a free account and receive a URL for your server. At this point you can access your data or share it from anywhere on the Internet with a web browser! As remarkable as that is there is more.

Codelathe markets a gadget they call the Tonidoplug. The plug has an embedded Linux distro, specifically Ubuntu 9.04. Besides the electrical plug (available for both European and North American standards) the plug has only two connectors, a USB port and an ethernet port. The idea is that you store data you want available on the Internet on a USB storage device and cable it to the plug. Use the ethernet port to connect to your hub or router. The embedded Linux runs the server so you do not need to be running it on your regular machine or even have your regular machine turned on! The Tonidoplug is priced at $99 (US) and equivalent euros.

With the free server you can access the Tonido App Store to keep the installed programs up to date or to buy new ones as they are developed. This is similar to the concept used by Apple on the iPhone. Do not expect many more free apps from Codelathe but the current free apps are well worth the download. This is a great way to share files. Unlike Dropbox and Ubuntu One, all your shared files are stored on a local device without a limitation on size before additional cost.

The machine had a recoverery partition so I booted into that. Recovery failed after about 90% complete. The partition was damaged. My final option was to download an XP Home .iso from a bittorrent site. This installed nicely. This is not necessarily illegal as the Windows install now requires activation. Of course. my customer had no knowledge of product keys or activation. I told her that the computer would only work for 30 days without activation and wished her good luck. I also gave her a copy of Linux Mint to install when Windows stopped working.

There are a few Windows utilities that will reveal the OEM install product key. Here is a link to one. If you are still using a legal copy of Windows, I strongly reccomend that you retrieve your product key. It may save you some grief in the future.

Air Sharing was an early (September 2008) entry into this arena. Currently the basic version that supports WebDAV is priced at $2.99 and a $6.99 upgrade adds print (to a wireless network printer) and email capabilities. Unfortunately, there seems to be a bug in Ubuntu that is preventing the setup of wireless printing. Once installed, Air Sharing will play or display all file types synced to it and supported by the iPhone platform. I have successfully synced a 350MB movie file and played it.

WebDAV is a file transfer protocol natively supported in both the GNOME and KDE desktops. The iPhone/Touch app will report its assigned IP address on the local network. Typically this will look something like http://192.168.1.101:8080. A GNOME user will go to Places>Connect to Server… and enter the IP and Port into the indicated fields. Depending on the app either a window will open or a folder will appear on the desktop. Files can now be synced to the device via drag and drop. Similarly, KDE users can use Konquerer to open “webdav://192.168.1.101:8080. With documents available locally, printing locally is possible despite the Ubuntu bug.

GoodReader is priced at 99 cents. The basic version supports WebDAV and email and like Air Sharing it will display/play all or most file types. A 99 cent upgrade adds the ability to sync with Google Docs. Again, the printing problem is solved. GoodReader has a free Lite version that will let you try all features before purchase. It is limited to five files. Another upgrade will add FTP ability if you prefer that protocol.

In combination, all the above apps provide you with an office suite for your iPhone/Touch. They will also work on the soon to come iPad. Apple has promised an office suite for the iPad. I can only wonder about what abilities that app will add.

Back in the days when I was a student, I always wondered if classmates who took copious amounts of notes ever really learned anything. It’s much the same with learning Linux. You can copy and paste a lot of commands but that is just blindly making changes. It is not learning.

Apply a tweak in the same way that you would use the command line. You should never issue a command until you understand exactly what it is doing. Neither should a tweak be applied unless the user completely understands its effects. I have pointed out before that the GNOME configuration editor is purposely not enabled in the menus to avoid newbies from messing up their desktop. And if you do tweak, I would strongly advise keeping a record of it in case strange events start occuring at a later date. I practice what I preach, and believe me, good notes have saved my day numerous times.

Tweak only with caution!

Transcode is available in the standard repositories. Install it from the command line (sudo apt-get install transcode) or use Synaptic. Here is the syntax of the command:

transcode -i input.avi – P 1 -s <desired gain> -N 0×55 -o output.avi

Let’s clarify this a little. Input.avi and output.avi are the names of your input and output files. If your input name contains spaces you should rename it to something without spaces. Otherwise you will have to use the “escape” character “\” for the command to parse correctly. For example “My Rip.avi” would be entered as “My\ Rip.avi”. This gets messy, so just rename the file.

0×55 is telling transcode that you want the output sound to be mp3 encoded. You can have other encodings if you so desire. Read the manual by entering man transcode on a command line for further information.

<desired gain> requires a little knowledge about decibels. Decibels follow a logarithmic scale. To double your volume you would enter a value of 3. A value of 6 would quadruple the volume. A value of 2 would result in an increase of about 60% Stay with low values, A value to high could damage your speakers, and sound distortion is likely. Replace <desired gain> with a value of your choosing.

That’s it for now. Let’s hope Ubuntu finally gets sound right in Lucid.

This post at UbuntuGeek instructs on how to install w32codescs and the mplayer plugin. Read the comments as they make some minor corrections to the post. Your success rate will immediately improve but will not be perfect. You might find, as I did, that using a stand alone media player like Banshee, xmms or VLC might be a better way to play the station than with a browser. Let’s use WRTI (Philadelphia) as an example. I like their music selection and I simply ignore the weather and traffic reports that are irrelevalent to me in Florida.

At the WRTI website you will see a LISTEN LIVE button. Clicking on the button will not work. However, if you right click on the button you can Copy Link Location to your desktop. It is a file with a .m3u file extension(classical-247-mp3.m3u). Open the file with gedit or any text editor. This reveals the url of a generic mp3 stream (http://wrti-ice.streamguys.net:80/classical-247-mp3). Opening this location in Banshee or in xmms will play the station. For some reason on my machine Exaile did not like it.

Your success with using Firefox will also be improved by installing the Novell Moonlight (aka Silverlight) plugin. Go to this wesite for installation. Please, no complaints from mono haters. I’m just telling you how to do it, it’s your choice whether to do it.

Finally, you can try RealPlayerGOLD11. It’s open source and promises to play Winows streaming media. I have not tried this but I want you to be aware of it.

Good Luck and Happy Listening!

The GNOME Configuration Editor is installed but not enabled by default. It is a powerful tool and should be used with caution only when needed. This was one of those times. To enable it, go to Applications>Preferences>Main Menu. In the left panel select System Tools. In the right panel check the box next to Configuration Editor. It is now enabled and obviously will appear under System Tools.

Start the Configuration Editor. Navigate the editor by clicking on the arrows next to the subsections. Click on the arrow next to apps. Then nautilus followed by preferences. Scroll down the options until you find the one called “show_desktop”. The box next to the option must be checked. To be sure, double click on the option and it should show a value of “True”. If it does not, recheck the box until it does.

The desktop icons on my machine reappeared. If you follow this procedure and you are not the sole user of the machine, you might want to go back and disable the editor for security.

Doh! Finally I realized that my graphis card might be the limiting factor. So how can you determine your card’s possible resolutions? First install the hwinfo package from the repositories. Bring up a terminal and issue..

sudo apt-get install hwinfo

Or, if you prefer, use the Synaptic Package Manager.

Then from a terminal issue..

sudo hwinfo –framebuffer

Your graphics card will be identified and you’ll see a listing of all possible resolutions. In my case, there was no vertical resolution greater than 768. Oh well!
