Last episode we talked about WSPR. Eddie Bennett, G3ZJO, wrote an article about running WSPR under Linux, and that article is available on the LHS website. He has several other blog pages, too.

Don, WS4E, wrote that he recently acquired an iPhone and was interested to see that there is a Ustream app for it, but the app only plays pre-approved streams. He wonders if the LHS and RF podcasts will be available on Ustream. Russ did contact them, and LHS is now available on the Ustream iPhone application.

We received a pingback from Ben, VK5JFK, to the article on the LHS website, Linux Mint 7 - Refreshing

Paul, KC9QYB, of teenradiojourney.com, writes about a problem he was having with a file server. They recently upgraded it to the latest version of Ubuntu server, on a separate partition. He wonders how he can recover the data from the other drives and partitions. Russ answers. Essentially:

Identify the “old” drive device name. You can search through the results of the dmesg command to see which devices are detected at boot. Let’s assume your old data is on drive /dev/hda1.

Create a directory in the /mnt directory on your new drive (or partition) to serve as the mount point. We’ll call it root:

Mount the old drive:

Now you can copy or move files from the old drive at /mnt/root to the new drive.

Similarly, you can create other directories in /mnt for other partitions, such as /var, /usr, /home, or whatever you might need.

A Twitter mention from timls about listening to the podcast.

Interview with David Lane, KG4GIY, and Shawn Powers of Linux Journal. Shawn is the Associate Editor and David is a contributing author, blogger, member of the Reader Advisory Board, and amateur radio operator. The January, 2010 issue of Linux Journal is devoted to amateur radio topics.

The very first issue of Linux Journal is available online, and also contained an article about ham radio.

David’s blog post about ereaders.

David is also the Emergency Coordinator and RACES officer for Prince William Cty, VA. David discusses the use of Linux in emergency communications.

Mentioned in the chat room: David Freese, W1HKJ, the author of fldigi, also has NBEMS, Narrow Band Emergency Messaging System, for Linux.

The group discusses how packet radio networks operate.

This leads to a discussion of what, if any, types of encryption are allowed in amateur radio transmissions.

Linux Journal has their “virtual ham shack” at https://www.linuxjournal.com/ham/, which includes a forum. David has recently started a thread there about software-defined radios.

The panel discusses what appears to be an increase in ham radio software for the Linux community.

Russ asks the panel their opinion about the new evil empire, Google, and specifically Google Wave and Google Voice.

What about Google DNS? https://code.google.com/speed/public-dns/ (The panel mentions “Cricket’s book”, which is DNS and BIND, by Paul Albitz and Cricket Liu, published by O’Reilly.)

With Oracle’s purchase of Sun, what will happen to MySQL?

Look for David at the Linux Journal chatroom on freenode IRC, in the #linuxjournal channel.
