I have a nice cassette deck that you would use with a stereo system and there are some old cassette tapes that I have never thrown out. Finally I’ve got around to copying some of these cassettes to files on my hard drive.

Here is a review of some software that I test drove on an old underpowered Windows XP machine: Exact Audio Copy, Wave Repair, and Audacity.        Read the rest of this entry »

October 19, 2014

Recently, I went to dump a MYSQL table into a CSV file, with the fieldnames in the first line of the file.

This simple enough in Oracle’s SQLPLUS, so I did some internet searches to determine the syntax.

Instead of the simple MYSQL syntax, I found a number of relatively complex solutions. Some involved MYSQL scripts, and others utilized Unix string parsing commands.

However, I came up with a much simpler solution using one simple MYSQL command:

October 4, 2014

Gimp is the GNU Image Manipulation Program. It is a freely distributed piece of software for tasks like photo retouching. I wanted to use it to crop photos, like Irfanview does so easily on Windows.

Unfortunately, like so many other software installations on Redhat Linux, the install was not straightforward and required overcoming errors. :(  Here’s how to install gimp on Redhat 6.4.

To query the files, you have to have the right version of sqlite. Turns out that an old version was installed with my Redhat Linux 6.4 installation and I had to upgrade it in order to see the data. Here is how you can install the software and query the logs.

sqlite3 ./cookies.sqlite 'select count() from moz_cookies'

Four Ways To Install Software On Linux

September 9, 2014

New to Linux?  Here’s some information that might be useful.
