LHS Episode #032: Screen-Doored Submarines

Posted on by Russ Woodman

Well, January has pretty much come and gone. I sure hope the rest of the year sticks around a bit longer. Now that it's 2010, though, Linux in the HAM Shack has a lot of things planned for the future: contests, interviews with fascinating and influential people, trips to live events throughout the year and, as always, scintillating content about Linux and ham shacks.

As of Episode #029, we have achieved more than 50,000 downloads. Episode #029 also turned out to be one of our most popular. When Richard and I started this endeavor back in October 2008 we didn't really know what to expect out of the podcast, but I think it's safe to say that whatever expectations we may have had, we're certainly reaching or exceeding them. I only hope that we only have more room to go up from here. Thank you to everyone who listens to, participates in, or otherwise helps out with the podcast--especially Bill, KA9WKA, our beloved Show Notes compiler, and everyone who has made a donation to the program. We are only about $100 in donations away from our booth at the 2010 Dayton Hamvention and we hope that we'll be able to set up there and say hello to all of our fans, old, new and undiscovered, when it finally rolls around.

But for now, we wish you a speedy download and an enjoyable listen.

LHS Show Notes #031

Posted on by Russ Woodman

Contributors:

  • 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:
    1. 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.
    2. Create a directory in the /mnt directory on your new drive (or partition) to serve as the mount point. We'll call it root: 
      mkdir /mnt/root
    3. Mount the old drive: 
      mount /dev/hda1 /mnt/root
    4. Now you can copy or move files from the old drive at /mnt/root to the new drive.
    5. 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.

Announcements:

  • We received a donation from Bill, NF9D, to help send Linux in the Ham Shack to the Dayton Hamvention in 2010. Thanks, Bill!

Links and Notes:

  • 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.
  • Check out the Linux Journal store, too.

Music:

  • "Let's Get It Started" by Oh No Not Stereo from the album "003"
  • "Miss America" by Beyond 7 from the album "Revelations Per Minute"

LHS Episode #031: Linux Journal Invasion

Posted on by Russ Woodman

Linux in the HAM Shack has arrived in 2010! It's hard to believe that 2009 is over already. We've have so much fun putting together the podcast for everyone, the time has literally flown by. Soon it will be time for the snow to melt, the world to turn green once again, and for LHS to travel to Dayton, OH for the 2010 Hamvention in May. We're so ready we can almost taste it.

In this episode, we had the honor of interviewing two prominent figures from Linux Journal magazine. David Lane, KG4GIY, is the magazine's eminent blogger and ham radio advocate. He is a large part of the reason the January 2010 issue of LJ is all about amateur radio. Shawn Powers is the magazine's associate editor, which gives him the dubious honor of being a guest on our show. He's the go-to guy when the editor, publisher and just about everyone else needs something done. We have to say we were greatly honored to have the LJ folks join us, and we sure hope we haven't scared them off so they'll come back and talk with us in the future.

Hope everyone is having a fantastic 2010 so far, and thanks for downloading LHS in the new year. And if you have a couple of dollars leftover from holiday binging, please drop us a donation as the deadline for acquiring a booth in Dayton is coming up fast. And remember, we appreciate our listeners, each and every one. Thank you!

LHS Episode #030: Whispers and Warnings

Posted on by Russ Woodman

We've reached the end of the decade. 2009 is just about over and 2010 is just about to swoop in and overwhelm us all. It's been a fantastic year here at Linux in the HAM Shack, and we'd like to thank all of our listeners and sponsors who make the show possible. Without you, we would literally be nothing.

Hopefully everyone has enjoyed their holidays, spent time with families, given and received all of the gifts you've hope to give or receive. Warmest wishes from our homes to yours during this time of friendship and togetherness, and please accept our gift of a new podcast to take you through the rest of this special time and into the upcoming new year. May it be more prosperous and fulfilling than the ones that have come before.

73 and Happy Holidays,

Russ (K5TUX) and Richard (KB5JBV)
