I'm going to call this an experimental episode. It's a tutorial on eding the Open Street Map at http://www.openstreetmap.org/ . By all rights, this should have been done as a screen cast, but since I have no interest in doing a screen cast, we're going to try something different. For this episode to work, I'll need your cooperation, and for it to make any sence to you, you'll need to be signed into http://www.openstreetmap.org/ . So go ahead and create an account over there (or begin the password reset process) while you're downloading this audio file. You're going to need an account if you want to edit anyway, so I'm not asking for anything you wouldn't be doing anyway. You may find it helpful to have a second tab open to http://wiki.openstreetmap.org/wiki/Map_Features . It won't be much help while listening to the episode, but it is very helpful while editing in general. Some people enjoy finding mistakes. For their enjoyment I have included a few. http://www.openstreetmap.org/ http://wiki.openstreetmap.org/wiki/Map_Features

In this episode Lord Drachenblut shows us how to start irssi in screen after reboot. crontab -e # opens editor for crontab @reboot /usr/bin/screen -dmUS irc /usr/bin/irssi -d -m Start screen in "detached" mode. This creates a new session but doesn't attach to it. This is useful for system startup scripts. -U Run screen in UTF-8 mode. This option tells screen that your terminal sends and understands UTF-8 encoded characters. It also sets the default encoding for new windows to `utf8'. -S sessionname When creating a new session, this option can be used to specify a meaningful name for the session. This name identifies the session for "screen -list" and "screen -r" actions. It substitutes the default [tty.host] suffix. https://www.gnu.org/software/screen/ http://www.irssi.org/ http://en.wikipedia.org/wiki/Cron

Due to an error in the encoding (ken's fault) the episode is been re-transmitted - sorry all I this episode NYbill talks about etching copper PCB boards at home..

The muriatic acid/hydrogen peroxide etching solution can be used multiple times. Store it in plastic or glass containers. The tinting fluid can also be reused. But, it will need to be agitated and or slightly heated (place container in a bath of hot water) before reuse as the mix will settle out.

Today's show is about Sonar GNU/linux and the importance of it. I'm also running an indegogo campaign and I mention it at the end the link to the campaign is http://www.indegogo.com/sonar The link to Sonar is http;//www.sonar-project.org

Linux In The Shell aims to explore the use of many commands a user can run in the Bash Shell. Tutorials include a write up with examples, an audio component about the write up, and a video component to demonstrate the usage of the command. The website is http://www.linuxintheshell.org/ In todays episode The sort command does just that, it sorts input.  Input can be a list of files, standard in, or files with standard in. The first example presents this simple file, shopping.txt,  containing a list of items: chicken fish sour cream bread crumbs milk eggs bread sinkers fishing hooks Issuing the sort command on this file: sort shopping.txt Would present the following output: bread bread crumbs chicken eggs fish fishing hooks milk sinkers sour cream For more information including a complete video please see http://www.linuxintheshell.org/2013/01/29/episode-022-sort/

Today we are doing the last show that has been in the syndicated Thursday queue for a long time. Now that we are no longer syndicating shows, I wanted to post this today so that we can get the backlog cleared. The show can be found at http://techandloathing.info/2012/11/tnl-episode-13-remote-desktop-protocols/ Hey listeners, another episode of Tech & Loathing is now on tap. A couple of IRC friends have joined me tonight to discuss a couple of topics. For Loathing we have Android vs. iOS and all of my frustrations with the world of mobile computing. For Tech we have a look at RDP, VNC and running applications and desktop environments remotely, either securely via SSH or VPN or insecurely using X Forwarding and other techniques. Hope everyone enjoys the show.

Synopsis of the Problem You may hae heard me mention that I purchased a used rack server a couple years ago to help teach myself Linux server administration.  It's an HP DL-380 G3 with dual single core Zeons and 12Gb of RAM.  It came with two 75Gb SCSI drives in RAID1, dedicated to the OS.  Since the seller wanted more for additional internal SCSI drives, and those old server drives are limited to 120Gb anyway, I plugged in a PCI-X SATA adapter and connected  750Gb drive externally and mounted it as /home.  I moved over the 2Gb USB drive I had on my Chumby (as opposed to transferring the files) and it shows up as /media/usb0.  I installed Ubuntu server 10.04 (recently updated to 12.04) because CentOS didn't support the RAID controller out of the box and I had frustrated the lack of support for up to date packages on Debian Lenny on the desktop. With 75Gb dedicated to the OS and application packages, you can imaging my surprise when after a update and upgrade, I had a report that my /boot was full.  It was until I look at the output from fdisk that I remembered the Ubuntu installer created a separate partition for /boot.  At the risk of oversimplifying the purpose of /boot, it is where your current and past kernel files are stored.  Unless the system removes older kernels (most desktop systems seem to) the storage required for /boot will increase with every kernel upgrade. This is the output of df before culling the kernels Filesystem              1K-blocks      Used  Available Use% Mounted on /dev/mapper/oriac-root   66860688   6593460   56870828  11% /udev                               6072216           4    6072212   1% /dev tmpfs                              2432376       516    2431860   1% /run none                               5120                 0       5120       0% /run/lock none                              6080936            0    6080936    0% /run/shm cgroup                           6080936            0    6080936   0% /sys/fs/cgroup /dev/cciss/c0d0p1          233191    224953          0         100% /boot /dev/sda1                       721075720 297668900  386778220  44% /home /dev/sdb1                     1921902868 429219096 1395056772  24% /media/usb0 This directory listing shows I had many old kernels in /boot abi-2.6.32-24-generic-pae abi-2.6.32-35-generic-pae abi-2.6.32-36-generic-pae abi-2.6.32-37-generic-pae abi-2.6.32-38-generic-pae abi-2.6.32-39-generic-pae abi-2.6.32-40-generic-pae abi-2.6.32-41-generic-pae abi-2.6.32-42-generic-pae abi-3.2.0-29-generic-pae abi-3.2.0-30-generic-pae abi-3.2.0-31-generic-pae abi-3.2.0-32-generic-pae config-2.6.32-24-generic-pae config-2.6.32-35-generic-pae config-2.6.32-36-generic-pae config-2.6.32-37-generic-pae config-2.6.32-38-generic-pae config-2.6.32-39-generic-pae config-2.6.32-40-generic-pae config-2.6.32-41-generic-pae config-2.6.32-42-generic-pae config-3.2.0-29-generic-pae config-3.2.0-30-generic-pae config-3.2.0-31-generic-pae config-3.2.0-32-generic-pae grub initrd.img-2.6.32-24-generic-pae initrd.img-2.6.32-35-generic-pae initrd.img-2.6.32-36-generic-pae initrd.img-2.6.32-37-generic-pae initrd.img-2.6.32-38-generic-pae initrd.img-2.6.32-39-generic-pae initrd.img-2.6.32-40-generic-pae initrd.img-2.6.32-41-generic-pae initrd.img-2.6.32-42-generic-pae initrd.img-3.2.0-29-generic-pae initrd.img

In this show I talk about the git version control system. I won't give example commands, but I discuss concepts like commits, branches, merging, push and pull, and rebasing. I also talk about the git workflow I use. I will put some more info on http://johanv.org/node/200.
