Last night my 4-year-old daughter Pascale and I assembled a PC for the kids to use. I reused gozer, my former HTPC, along with a monitor given to me by my friend Soren, and a keyboard and mouse purchased for tiny hands. I installed Qimo 2.0, a children-focused Linux distribution based on Xubuntu 10.04 “Lucid Lynx”.
You are currently browsing the yearly archive for 2012.
Run an Ubuntu system long enough, and you’ll eventually have a large number of kernels installed. These don’t cause any harm, but they do take up disk space and appear in the GRUB menu at boot. So every now and again, I take a moment and purge the old kernels.
Update 2013-02-18: See comments. The exclude location is now /etc/ownCloud/sync-exclude.lst, with no user-specific exclude file.
I’ve been playing with ownCloud and just set up the sync client for Ubuntu 12.04. One immediate issue I encountered is that it tried to sync files I wanted it to ignore, like Vim’s swap (.filename.swp) files.
Update 2013-10-02: This issue has been resolved with BackupPC 3.3.0.
A number of people of reported issues backing up Windows hosts with SMB and BackupPC 3.2.1 on Ubuntu 12.04 precise. This is caused by a bug in Samba/smbclient since 3.6.x where excluded directories are still listed (even if they won’t be backed up). It has not yet been fixed, but there is a workaround: downgrade Samba to 3.5.x.
My team manages a number of user workstations running Ubuntu 12.04 “Precise Pangolin”. We install a standard APT configuration which automatically upgrades these PCs as soon as packages are available, without prompting and without a GUI. Therefore we also need to disable the update-notifier so it doesn’t display these packages to the user.
I recently upgraded my home server from Ubuntu 10.10 maverick to 12.04 precise. I ran “do-release-upgrade” three times, upgrading through natty and oneiric. The process was very smooth, but I found a few bugs with BackupPC. If you are using BackupPC 3.2.1 on precise, or plan to upgrade soon, I suggest you read the following.
Time marches on, and so do all those little changes in Linux distribution releases. Most of my really popular blog posts are how-to guides on complicated-but-useful procedures for the technical Linux user. Those users are the same ones who may read the date in the URL and say “Ewww, this was written three years ago, it must be totally outdated now!” I’ve decided to update the most popular posts to bring them up to date. This post is “Using host networking and NAT with VirtualBox“, version 2.0.
I’ve just upgraded to Ubuntu 12.04 LTS “Precise Pangolin” on a number of devices. It’s been smooth so far, and I’ll write up the issues I’ve found soon. In the mean time, I’ve added a few packages to the precise repository.
I’ve added several packages to the repository recently. I still use maverick, the last release before Unity became the default. I intend to move to Unity with precise, but until then I’ve been backporting things to maverick.
- maverick: fceux 2.1.5, backported from precise
- maverick: get-iplayer 2.8.0, taken directly from precise
- lucid: logcheck 1.3.14, backported from precise to correct a problem with wildcard globs in the lucid release
XBMC 11.0 “Eden” has just been released. So far, it’s sexy. So sexy.
After the upgrade, one key on my Logitech diNovo Mini keyboard stopped working. Previously, I had configured the “Media” key in the lower right corner to switch between full screen and windowed mode, so I could access the normal Ubuntu desktop. However, this now launches the Music Library. They keymap for this key changed from <launch_media_center> in Dharma to <launch_media_select> Eden.
This file corrects it.
