When XFCE and emacs colide

Filed under: Programming,System Administration — Cranky Sysadmin @ 7:49 pm

Xubuntu 14.04 has decided to abscond with a couple of keys that I use for emacs, and I want them back! The first key is C-space, which emacs uses for setting a mark. I use this all the time and I’m not willing to do without it. It turns out that there is this feature called IBus which steals the key and uses it to switch input methods (for entering foreign characters I’ve read). To change this behavior, right-click on the ibus panel applet, and select preferences. You’ll see “Next input method” and it’s bound to C-space by default. you can use the intuitive “…” button to change this. I changed it to FN-space (called “Launc6” on my keyboard). Next up is the capslock key, which I rarely use except in shell scripts. I’d like to bind it to the ctl key. Since I haven’t decided whether I want to do this permanently, I wrote a script to give me some options.


case "$1" in
	CMDNAME=`basename $0`
	echo "Usage:"
	echo "$CMDNAME [caps|nocaps|swapcaps]"
	echo "----------------------"
	echo "$CMDNAME will adjust the mapping of your left ctl and capslock keys."
	echo "an argument 'swapcaps' swaps the two keys"
	echo "'nocaps' changes the capslock to a ctl and leaves the left ctl as-is"
	echo "'caps' returns the keys to the original settings"
	exit 1

/usr/bin/setxkbmap -option '' -option "ctrl:$1"

Run it with no arguments to get some help. I currently prefer nocaps.

Edimax wifi with BeagleBoneBlack Angstrom 6.20 image

Filed under: Electronics,System Administration — Cranky Sysadmin @ 8:52 pm

This process was relatively straightforward for me, but it required looking at several sources. I don’t compile any kernels. I just found the appropriate firmware and loaded it on the bbb. I then did some hand waving and sacrificed a chicken and it all worked. Check below the fold for details.

Many Upgrades to Ubuntu 12.04

Filed under: System Administration — Cranky Sysadmin @ 6:28 pm

On the desktop, I’ve migrated from ubuntu 11.04 to xubuntu 12.04. It was relatively pain free. Unity isn’t my first choice of desktop, and XFCE reminds me of CDE, so I like it. I still can’t compile a custom wine on a 64 bit system, but the packaged wine is good enough for now. At my place of employment, we’ve been moving servers from 10.10 to 12.04. Where we upgrade, there are various unrepeatable problems from one server to another similar server. Most of the “upgrades” have been a swap out of an old instance for a new, which goes better. We’ve encountered problems with the database migration and with openssl/libssl. It reminds me why I like RedHat/CentOS on the server side.

Coming Upgrade to this server

Filed under: System Administration — Cranky Sysadmin @ 11:31 am

Soon, I will be upgrading this server. Maybe just the OS, or maybe the hardware and OS. The data from this blog may or may not make the transition.

Ubuntu and the Asus G73SW-A2

Filed under: Games,System Administration,World of Warcraft — Cranky Sysadmin @ 10:30 am

My wife was kind enough to let me go purchase a new laptop. I chose the Asus G73SW-A2. Aside from games, I’m doing a lot of work with virtualization, and the 16GB of RAM will make this easier. I got the laptop on Amazon for about $2000 plus shipping. It’s a great value.

Studying the Turbine Outage

Filed under: LOTRO,System Administration — Cranky Sysadmin @ 9:32 am

I wouldn’t have wanted to be an operations guy at Turbine this past weekend. From about 1PM (US/Eastern) to about 8PM, all of the customer facing bits at Turbine were inaccessible as far as I could tell.

Hadoop? What kind of a name is Hadoop?

Filed under: Programming,System Administration — Cranky Sysadmin @ 8:03 am

Briefly, as I understand it, hadoop is a distributed program which allows one to aggregate data by processing across a bunch (more than 2) of computers. The name apparently comes from the name the lead developer’s son gave to his stuffed toy elephant. It’s not just the name that I dislike though.

This year for Christmas, my wife got me an Acer Aspire AS8940G-6865. I immediately set about installing Ubuntu 9.10 and all of my games.

Tiny Linux Boxes

Filed under: Mobile Technology,System Administration — Cranky Sysadmin @ 11:07 am

While cleaning out my um…. home office storage area (closet in the guest room) I came across a couple of gems which I had forgotten about, two Sharp Zauruses (Zauri?). One is a fairly old SL-5500. The other is a slightly less old SL-C3000.
