Announcements:
- The drawing for the Southeast Linuxfest prizes will be next episode.
- Problems with GoDaddy prevented the download of the last episode for a time. It seems to be fixed now, but we may be moving to another hosting company.
- Visit https://wiki.edubuntu.org/UbuntuHamsNets for a list and schedule of ham radio nets for Ubuntu users. Everyone is welcome!
- Some listeners reported problems playing the OGG file of the show with VLC. All episodes through #35 worked, but #36 and later did not play in VLC. The problem was that the cover art image was too large for the OGG file metadata specification (64KB), which caused VLC to choke. The Totem player was not respecting the specification and would play the file anyway. The cover art image was reduced to less than 64KB, and the OGG version of episodes 36 onward have been repaired and should now play properly in VLC.
- Would you object if LHS was only available in OGG format? Let us know!
- LHS has an online assistance feature! There's a Live Support button on the right-hand side of the LHS web page that will initiate an interactive chat session with the hosts of the show, if they're online.
- The "Thesis" WordPress theme has caused controversy as it's not GPL, but because WordPress is open source, and the theme is a derivative of the WordPress program, then Thesis should be GPL, too. See the articles on Geckotribe and Mixergy for more on this topic.
Donations:
- We received donations from Jonas and Ross, both in the chat room tonight. Thank you!
Feature:
- Richard and Russ discuss Logbook of the World, TQSL, and support for Linux.
- Dave, KG4GIY, sent along some information about TQSL support for Linux being dropped by ARRL, which would cause problems for applications such as CQRLOG.
- There is a SourceForge project that provides software to build the TQSL libraries under Linux. Russ came up with the following procedure to build the software under Ubuntu, or you could just try executing:
sudo apt-get install trustedqsl
-
Building TrustedQSL under Ubuntu
- Install the required libraries:
sudo apt-get install libssl-dev libexpat1-dev zlib1g-dev g++ build-essential
- Download and extract the tqsllib and TrustedQSL software from SourceForge
- A minor change is required in the openssl_cert.cpp file from the tqsllib package to add an if statement allowing it build on recent versions of Linux with openssl 0.9.8. In patch format, the code for this update is at the bottom of this section.
- Execute the following commands to build the library:
# ./configure # make # make install
- Install the required libraries:
- Again, if you're using Debian, Ubuntu, Linux Mint, or similar Debian-based Linux, you can simply type
sudo apt-get install trustedqsl
and not bother building the library yourself. In the end, your Accessories menu will contain tqslcert, used to get the certificate from ARRL, and TrustedQSL, used to encrypt your ADIF log data and submit it to LoTW.
- Applications like CQRLOG will then work with LoTW.
- Russ describes the process for obtaining a certificate from the ARRL.
- The ARRL also seems to contradict itself in its support of Linux. On the Resources page, under the entry for CQRLOG for Linux, it says "Please note that ARRL does not support Trusted QSL for Linux." However, the FAQ page says "At present one needs to use a computer with Windows or Linux operating systems to use TQSL and TQSL Cert."
- Richard suggests we all should send a letter to the ARRL demanding Linux support in LoTW.
- Paul, KE5WMA, in the chat room points us to the Ubuntu Linux for Hams article posted July 26, 2010 at ARRL.

Feedback:
- Scott, N9LJX commented on the web site about his desire for a decent logging program for Linux that interfaces with LoTW. CQLog is close, he says, but lacks in the award tracking area. So, unless we can offer an alternative, he's staying with Windows and the DXLab suite. Russ and Richard discuss CQLog (a Windows program) and CQRLOG (a Linux program). Perhaps, at the moment, Windows and the DXLab suite is the best solution for you, or you might try running Windows in a VirtualBox session under Linux.
- Jason, KB9LAF, asks if we know of any Linux software that will run his Icom ICPCR-1000 receiver. Russ found this article in the Ubuntu forums. (Ed. note: Here are a couple possibilities: A Python application that will run under Windows or Linux, and IcomLib.)
He also mentions Pendrive Linux as a means of running Linux from a USB drive.
Thanks, Jason. We talked about that in Episode 19. - Kallie asks if the New Logo contest would reopen and asks why it was cancelled. There were no entries, so Russ paid for a new logo. But feel free to submit your art, if you wish.
- Tim, KI6BGE, writes about his trouble with PCMCIA wired and wireless network cards under Linux Mint 9 LXDE on his IBM T21 laptop. They used to work with SUSE. Any suggestions? Russ and Richard discuss. They suggest running lsmod under Ubuntu to determine which drivers are loaded when the network cards work, then check what lsmod shows under Linux Mint, determine what's missing, and modprobe the missing drivers.
