Some Red Hat Notes

I was working on Red Hat today and took a couple of notes:

Finding what drives are available on the system

fdisk -l

Mounting the found device

mount /dev/hda1 /mount/somedrive

Aqua Studio

If you are having problems connecting to a Oracle Instance using Aqua Data Studio that has a similar tag:

jdbc:oracle:thin:@//58.37.64.169:1521/MyDB

On a Macintosh you are best to use SQLGrinder. I have found that Aqua Studio doesn't handle service name varient too well.

The Oracle thin driver supports two variants of the database specifier: the service name and sid variants. Oracle highly recommends using the service name version of the connection URL. In fact they no longer describe the sid version in their current documentation. We describe both because some users may be more comfortable with the traditional sid over the new service name.

Package javax.servlet does not exist

Package javax.servlet does not exist
Apple.com says: For some reason, the necessary packages are not in your classpath. Debug your classpath to make sure the javax.servlet.* classes are there. If the classes are not found, the resolution is to download the servlet.jar and put it into /Library/Java/Extensions or in your classpath. The servlet.jar can be found with many open source distributions (such as tomcat).

Update
This morning I got the above message, but it turns out that the classpath in build.xml file was pointing to the wrong directory. If you are getting the above error, make sure that your classpath in build.xml is set correctly.

xD Picture Cards

It's amazing how quickly card readers have come down. Here's three orders that I placed in the past few years.

December 31, 2004
Sandisk 512MB XD Picture Card Retail @ $85.00

February 10, 2006
Olympus 1GB XD Picture Card Retail @ $73.99

August 24, 2006
FujiFilm 1GB xD-Picture Card Retail @ $39.99

Today the 2GB xD-Picture Card retails for $65.87 at Amazon. I wonder what the price will be like a year from now.

G4 Computer in 2001

Wow has times have changed. The above is the root level listing of my G4 400 series computer on January 21, 2001. This shows you all the applications that I used all the time on my computer.

What I thought was cool then is no longer cool today. What ever happended to CD Master, Fusion Recorder, VideoShop. Six years from now, I wonder what I'll be thinking of the applications that I use today.

The main use of this computer was for video encoding, that's why you see a lot of video applications, such as Video Shop, Media Cleaner and Fusion Recorder.

A lot of thought went into ordering the applications on the main window. The way the listing works is:

• Top Row are all the Root Folders, including the System Folder.
• Second Row contains all the importaint applications that I use. With IE, and BBedit being the most frequent.
• Third Row has all the secondard Applications. Netscape is first because it flows better having it below IE.
• Forth Row contains Utilities and Video Applications.
• Fifth Row has all the fun apps
• Six Row are rarely used but essential applications. Anarchie is on the bottom row because I didn't do much FTP on this computer since I only had dialup access.
