Show Notes #095

Posted on by Russ Woodman

Introduction:

  • Welcome to episode 95 of Linux in the Ham Shack. Episode 100 looms on the horizon, and we'd like to do something a little special. Call in to the LHS voice mail line at +1-909-LHS-SHOW (1-909-547-7469), or send an email, and share your thoughts about the show.
  • LHS recommends this LOL Cat image.

Announcements:

  • Kevin O'Brien, Publicity Director of the Ohio LinuxFest, is looking for someone to step up and take on the role of Volunteer Coordinator. If anyone is interested please reply to news@ohiolinux.org.
  • We now digress into a ramble about censorship.
  • On page 45 of the December 2012 issue of QST has an article on vertical vs. horizontal antennas, a topic we discussed in episode 91. In the same issue, on page 52, there is also an article about the NorthWest Digital Radio UDR56K, a topic we discussed in episode 90. Are we seeing a pattern here?
  • Also in that issue is a description of several FCC Proposed Rule Changes, and our hosts discuss each of them:
    • Reduction of license expiration grace period from 2 years to 6 months.
    • Reduction of vanity call waiting period from 2 years to 6 months.
    • Reduction of the number of Volunteer Examiners at test sessions from 3 to 2.
    • Possible allowance of "remote testing" facilities using video and audio over a network that allows for proper administration of tests.
    • Allow single-slot TDMA transmissions.
  • The 2012 Fort Wayne Hamfest is this weekend, November 17-18, in Fort Wayne, Indiana. This is also the ARRL Convention for Indiana. This launches Richard into reminiscing about the presentation of The Last Voice from Kuwait.

Topics:

  • Symbolic (or soft) Links vs. Hard Links
    • Russ and Richard offer a discussion of the difference between soft, or symbolic, links and hard links in Linux.
    • A symbolic link is a pointer to another file name. Symbolic links can be created with the ln -s command: 
      ln -s [original file] [link name]
    • Symbolic links can point to files on other volumes or file systems.
    • Hard links, on the other hand, are pointers to the data of another file, just like a directory entry is a pointer to the first block of data for the file. Hard links are also created with the ln command, but without the -s switch.
    • Hard links can only be used on the same file system.
    • A symbolic link is equivalent to a Windows shortcut, a pointer to the name of another file. A hard link is a reference to the data (first inode) of another file, and thus must be created on the same file system.
    • When the original file with associated hard links is deleted, the data remains until all of the hard links are also deleted. Deleting the original file with associated soft links will delete the file and the data, but the soft links will remain, now orphaned.
    • More information about links is available here.

Feedback:

  • Listener Dave left a comment on the web site expressing his appreciation for the show, and also became a subscriber. Thanks, Dave!
  • Jeremy, KD5HQN, also commented on the web site, claiming he's actually learning something from the shows! He also corrected Richard about the proper location of Orthanc. Thanks, Jeremy.
  • Bill, KJ4KNI, asked, via Richard's Facebook page, for suggestions about the best Linux distribution for a beginner. (Linux Mint 13 is a good choice.) He also wonders why a ham might use 75-ohm RG6 coax as an antenna feedline. Our hosts discuss the possibilities.

Show Notes #094

Posted on by Russ Woodman

Introduction:

  • No music this episode.
  • It's the night before Halloween and we're off to another spooky episode of LHS with our hosts starting with a ramble about horror movies. It's a trick AND a treat!

Announcements:

  • Please consider donating to the podcast or subscribing for #20/year. Also, the free Black Sparrow Media app is at risk of disappearing unless our listeners are willing to provide $15/month to keep the download site alive. Please contact us if you can help.

Topics:

  • Creating a desktop wallpaper slideshow in GNOME:

    It's actually a built-in feature of GNOME. Briefly, here are the steps:

    • As root, create a new directory in /usr/share/backgrounds (any name you want).
    • In that directory, place your desired background images (or links to them).
    • There's already a directory in /usr/share/backgrounds called cosmos which you can use as a guide.
    • Copy background-1.xml from the cosmos directory into your new directory and edit it to specify your images.

    More information can be found in this askubuntu thread. Be sure to read through all the comments.

  • Richard points us to one of many articles about ham radio operators helping out during and after Hurricane Sandy. Our sympathies to the victims of hurricane.
  • More about EchoLink and Linux: Richard found the CQiNet project, which includes two applications, Echolinux (an EchoLink client for Linux) and The Bridge, an iLink/EchoLink compatable conference bridge. Of course, there is still the svxlink package, which includes the Qtel Echolink client.
  • C'mon, people, where are my Raspberry Pi suggestions? Russ is still looking for good uses for his Raspberry Pis. Send your suggestions!
  • Google Webfonts are open source fonts that can be embedded in Joomla, WordPress and others, embedded in CSS, or with Javascript. Visit Russ' blog page for an example of Google Webfonts in action.

Feedback:

  • David, KE0AZ, sent an email about our discussion of antennas in Episode #091. He's opting for a used 4BTV vertical.
  • Tim, KI6BGE, in response to Richard's computer power supply repair in Episode #092, shares his success story involving a printer repair he attempted.
  • Scott, N8VSI, sent this audio report on his experience as the LHS ambassador at the Ohio Linux Fest. (We talked to Scott in Episode 93.)
  • Harrison, VE2HKW, made a donation to the Black Sparrow Media app server fund. Thanks, Harrison!

Show Notes #092

Posted on by Russ Woodman

Introduction:

Announcements:

  • Texoma Hamarama will held October 26-27, 2012 at the Ardmore Convention Center in Ardmore, Oklahoma. Pre-registration ends October 20th.
  • The Augusta Hamfest will be Saturday, October 13, 2012 in Augusta, GA.
  • Scott, N8VSI, was the LHS ambassador at the Ohio LinuxFest, September 28-30, 2012. We look forward to hearing a report from Scott in the near future.

Topics:

  • Richard recounts his experience replacing a computer power supply. Moral? Don't be afraid to try repairing a computer yourself. Swapping parts is easier than you might think. For power supplies, pay attention to the wattage required. (Ed. Note: When in doubt, it's best to replace the bad supply with one that has the same or greater wattage rating.)
  • Departing from our usual topics, Russ and Richard discuss a couple applications for producing slide shows and panoramic photographs:
    • Imagination is a lightweight and simple DVD slide show maker for Linux and FreeBSD that's very easy to use, offers a wide variety of transitions, supports background music, and much more. Available in the Debian and Fedora repositories, and probably many others.
    • Hugin is a program that allows you to assemble a mosaic of photographs into a complete, immersive panorama, stitch together any series of overlapping pictures, and much more. It's cross-platform and easy to use.
  • Why Ham Radio? Richard talks about why you might wish to obtain an Amateur Radio License and how you can combine it with Linux, including:
    • Getting your ham license for our non ham listeners.
    • There are many modes of communication, including voice, Morse code, and many digital modes.
    • The ease of getting your license.
    • Why you should get your license.
    • How to get your license.
    • The Amateur Radio Relay League (ARRL) is a good source of information
    • Free practice tests are available at qrz.com
    • A list of certified Volunteer Examiner Coordinators is available at www.ncvec.org.
    • Test sessions can be found through the ARRL and many local radio clubs.
  • Russ describes Universal Plug 'n' Play devices (UPnP). Many new devices offer the ability to play media from UPnP servers. It makes sharing your media very convenient and easy, but can also be a security risk.

Feedback:

  • Pete, VE2XPL, sends a long email in response to episode 88, and covers such things as the Toonie, Alexandre Graham Bell, Brad Sucks, the wAVEgUIDES PodCast, SouthCARS, email addresses for LHS, and the MintCast.
  • Ted, WA0EIR, asked if there is a problem with the LHS mailing list as his attempts to post a message there "bounced". Yes, the mailing lists have been broken, but they're fixed now.
  • Larry Bushey of the Going Linux podcast says thanks for the great show, and admits they stole the LHS "badger" sound effect for use on their show. Episode 185 contains an example of their use of the Badger.
  • LHS was mentioned in a comment to a post at hak5.org.
