HonkeyMagoo talks about his expeience at NELF 2014

•Held at the Residence Inn Marriot Hotel in Cambridge, MA
•Got there early and talked for a while with a guy who works in IT for a school system in VT. He converted all his middle school kids to Ubuntu.
•Got to meet Tracy Holtz, Russ Wenner, Martin Obando, Pokey, Flying Rich, Door, Jonathan, and Bruce. I also got to talk to a person by the name of Will Weaver. He gave a talk on docker that I am sorry that I missed. Docker seems very interstinig and hope to try it out soon. I missed his talk but all of the talks are posted on

The talks I saw were:

• Jon “Mad Dog” Hall: My twenty years in Linux
• Chad Wollenburg: Open Source in Education
• Paul Asadoorian: The 10 Commandments of Embedded Device Security
• Tracy Holtz: Open Source in Small Businesses
• Door to Door Geek: Recording Professional Podcasts in Open Source
• Ask the Geek: A Panel Discussion Moderated by Russ Wenner

Fiftonefifty discusses the utility byobu

byobu – A wrapper for screen and tmux
•Usage byobu-tmux [tmux options] , byobu-screen [screen options] , just byobu defailts to tmux
•The Caption line shows your open windows, and highlights the one upon which you are focused, and optionally displays your user name, host name, IP address, and a hint that there is a Menu available if you press F9.
•The Hard Status line consists of color coded output and symbols with configurable and dynamically updated facts, statistics, and information about the local system.
STATUS NOTIFICATIONS are fully documented in the linked reference

Key Bindings that I find moste useful
F2 Create a new window
F3 Move to the previous window
F4 Move to the next window
F5 Refresh all status notifications
F6 Detach from the session and logout
Shift-F6 Detach from the session, but do not logout



chattr: xy problems: when someone says they’re having trouble downloading and compiling glibc, see if it’s an xy problem.
  • User wants to do X.
  • User doesn’t know how to do X, but thinks they can fumble their way to a solution if they can just manage to do Y.
  • User doesn’t know how to do Y either.
  • User asks for help with Y.
  • Others try to help user with Y, but are confused because Y seems like a strange problem to want to solve.
  • After much interaction and wasted time, it finally becomes clear that the user really wants help with X, and that Y wasn’t even a suitable solution for X.
chattr: a user asks in irc: ‘anybody experienced in enabling posix shared memory in mint 13 ? … I have added the fstab line and mounted … but returns none and tmpfs returns both ?’ This question got me to thinking about the difference between what the mount command outputs and what’s in /etc/fstab. Poking around search results lead me to the kernel source code documentation and the Linux from Scratch book: 7.4. Device and Module Handling on an LFS System [udev] (and maybe 7.5. Creating Custom Symlinks to Devices )
Honkeymagoo: Raspberry Pi Server
I had installed too much crap on my regular server (Owncloud, Elgg, WordPress, Plex etc.) and thought it was time to wipe it and start over. I figured in the mean time I would try and use one of my Raspberry Pis as a file sharing server. I had talked to serveral people about using Owncloud on the Raspberry Pi using Nginx as opposed to Apache so I shut down my server and started this project.
  • started with a minimal Raspbian based distro called MinibianMinibian is basically Raspbian without X and ssh already set up.
  • Next I installed Samba for file sharing (2 quick hints always always always make a back up of your smb.conf file before doing anything. Second pay attention to file permissions. Things like chmod and chown are your friends. Also if anyone can give a good explanation of the difference between chmod and chown I would like to hear it. I know there is a difference I’m just not sure what exactly it is.
  • Next I WAS going to install Owncloud with Nginx but Kwisher told me about a little program called Seafile. Seafile is a web based file sharing program.
  • Some quick thoughts about Seafile. It runs real smooth. Better than Owncloud did on my old server. I don’t like the fact that files that are uploaded to the server are not saved in a way that would make them easily accessible to the server admin. I think they are encrypted on the server side. I want to play with it more because they have a command line client for linux and I want to try syncing files and see if that might solve my problem of not having the files accessible on the server.
  • Next I had heard about a web based email client called Roundcube. I first heard about this program on a podcast called SourceTrunk, a great podcast where the host reviews and tests out open source software (episode 096, released 2014-01-30). I thought I could benefit from a web based email client because I had a desire to run an email client but I am not always able to be at my computer, though I can sometimes get internet access. So I thought this might be fun to try out.
  • Roundcube is in the raspbian repos so I tried just a straight apt-get install roundcube. It stalled out midway through because it saw sqlite. so I had to install the rest by apt-get install mysql. Then I had to download the latest package of roundcube off there site and compile it.
fiftyonefifty: Automatically Launch Applications in Linux
  • Of course, the traditional way is to put it in /etc/rc.local (note, in some distros you might have to make rc.local executable).  But this won’t work for a application that needs to run under X, like a mixer.
  • Most desktops have their own way of autolaunching apps, but if you move between desktops, you may want to configure autostart only once.
  • Find the dot desktop file for the application. (Most applications that appear in you menus will have a .desktop file in /usr/share/applications/. I found kmix.desktop in /usr/share/applications/kde4/).
  • Copy it to ~/.config/autostart/ or /etc/xdg/autostart (depending on the values in $XDG_CONFIG_HOME and $XDG_CONFIG_DIRS).
  • Use chmod to make it executable.
  • Solution: We solved this during the show.  Apparently, there is not good autostart for every desktop, because desktop apps should load after the window manager.  For lxde, autostart is /etc/xdg/lxsession/LXDE/autostart



-FiftyoneFifty talks about how he fixed his display manager issues after a recent Debian Sid dist-upgrade.

-chattr gives an update of his RockBox and some recent troubles. Plus, apt-get or aptitude: in debian, while the advice used to be ‘use aptitude or use apt-get but don’t switch back and forth’ that’s no longer the case: you can use both. apt-get-or-aptitude-pick-the-right-debian-package-manager-for-you. Hertzog is one of the maintainers of dpkg in debian: Packages overview for Raphaël Hertzog which lends his view great weight, imo.

Log files: aptitude writes /var/log/aptitude (yes, no filename extension) and /var/log/dpkg.log and /var/log/apt/term.log and /var/log/apt/history.log

apt-listchanges and apt-listbugs: these are scripts which run after apt-get install or aptitude install downloads the .deb files: apt-listchanges can compare a new version of a package with the one currently installed and show what has been changed, by extracting the relevant entries from the Debian changelog and NEWS files. apt-listbugs lists critical (chattr was mistaken when he said severe, grave and important) bug reports from the Debian Bug Tracking System. It runs after downloading the .deb files to see if an upgrade or installation is known to be unsafe

-Listener feedback gives us a good tip on how to fix clicking wheel troubles for Sansa e260 devices.

-Honkeymagoo gives us a quick look at fstab and how he mounted a USB drive to his server.



Sansa Clip Zip and Sansa Fuze running rockbox

I’ve been running rockbox on my Fuze since late 2010 (first time I /joined #rockbox on freenode was Fri Oct  1 2010.

Go to, locate your player make and model, download the rockbox manual for your player, read through the manual, download the install utility and you’ll get some basic themes. you can select other themes from

Rockbox on my devices supports sdhc cards up to 32GB along with internal storage. I used fdisk to partition the card and mkfs to put a vfat filesystem on the card.

Boot into the stock firmware and put the Sansa device into usb|msc mode, mount the device and run the installer. The default mode is mtp, and I have never tried to access either device in mtp mode, only usb|msc mode. The installer is a graphical application. The installer handles everything, all you need to know is where the device is mounted. The installer puts a bootloader and the rockbox firmware on the device. When you power on the device, you always have the option to boot into rockbox or boot into the stock firmware.

I got a Clip Zip as an emergency backup player: sooner or later, I expect the Fuze to fail (nothing electronic lasts forever).

Many additional features are available in rockbox compared with the stock firmware: file manipulation and listing, a database is created of all the files, so you can select what file to listen to by selecting a file from the file listing or selecting using the database listing.

The Fuze Clip Zip with rockbox has fewer features than the Fuze. The Fuze uses a wheel with center button (select) while the Clip Zip used a north-south-east-west selector plus center button. My muscle memory for navigating and selecting files or features, is better with the Fuze.

The Fuze Clip Zip uses the center select button for a lot more than the Fuze, and different actions are triggered by short, medium and long select presses.

Both devices use proprietary cables for data transfer and battery recharging. Battery life seems about the same for both devices: I’ll start an eight hour work shift with 100% battery and by the end of the shift, having listened for 5 or 6 hours, I’ll be at maybe 40%.

The Fuze sometimes resets when copying a file and I have to wait for the process to stop, unmount and remount the device. Once a month (or less often) my machine crashes and I have to do a hard reboot: maybe a bad cable, wrapped|folded too many times?

I’ve only listened to .mp3 or .ogg files on both devices. There may be some way to watch videos, but I’ve never tried.

There may be a way rockbox can increase the audio playback tempo per file, but I’ve not looked into doing that. (Increasing the playback without altering the voices so they sound like Mickey Mouse.)

5150 Talks about creating an IRC Channel
Registering a Freenode.Net IRC channel and setting up operators

• Establish your new Freenode channel
• Freeenode was originally set up to support development projects and that is still reflected in their mission statement.
• To register a channel, you must have a registered nick
• Channel  naming official (primary) channels start with a single hash.   Secondary, unofficial channel names start with two hashes.  Say we  wanted to create a sub channel to discuss the design of the web page, we  might call it ##LinuxLUGCastWordpress
• Check the availabilty of the the channel you want to register.  Freenode says to use /msg ChanServ info #MyNewChannel , but  that command never returned anything for me, even with channels I knew  existed. Do worry, ChanServ won’t let you register a channel name (case  insensitive) that already exits.
• All you have to do to create a channel is to join it /join #MyNewChannel   Note, you re automatically set as admin for this channel.  Of course,  if you don’t register the channel (or hold it open with a bot), it will  disappear as soon as all users leave.
• Now register your channel /msg ChanServ register #MyNewChannel
• Set yourself up as administrator (Operator, or op) for your channel
• But  I’m already an op since I created the channel, you say.  Not so much  I’m afraid.  Leave the channel and come back, see, you are no longer OP.
• You are not an OP but you are the Founder, which gives you right to make people, including youself, OPs
/msg ChanServ OP #MyNewChannel MyNick
• If you want to set up your fellow OPs at this point use /msg ChanServ OP #MyNewChannel OtherOpNick
• Set operator defaults for yourself and your fellow operators
• But  wait a minute, I’m still not an OP!  If you are using a GUI IRCmanager,  like XChat, if you right click on your name you will find a menu item  like “Operator Actions”, and under that “Give Ops” and “Take Ops”.  You  can elevate yourself here, and you can do the same for the others you  made OPs (though they won’t be able to do it for themselves yet).
• You  set operator defaults with the FLAGS command.  The +O arguement means  the user will always join the channel as an OP, +o joins them as a  regular user with the option to elevate themselves, i.e:
• You always want to join the channel as an OP, issue: /msg ChanServ FLAGS #MyNewChannel MyNick +O
• If you want the other OP you created to join a a regular user with the power to make themselves an OP, issue:  /msg ChanServ FLAGS #MyNewChannel OtherOpNick +o
