Dell announced that a few more models are now available pre-installed with Ubuntu: the XPS 1530n and the Studio 15n.
I configured an XPS 1530n with the following specs, which are available both with Ubuntu and Windows:

SYSTEM COLOR
Tuxedo Black

PROCESSOR
Intel® Core™ 2 Duo T5850 (2.16GHz/667Mhz FSB/2MB cache)

LCD AND CAMERA
Full Hi Definition, glossy widescreen 15.4 inch LCD (1920×1200) [...]

So you’ve done quite a few dapper to hardy upgrades, and you’re ready for the next one.
You

apt-get update
apt-get upgrade
apt-get install update-manager-core

and then

do-release-upgrade -d

You go get a cup of tea, and come back to

# do-release-upgrade -d
Checking for a new ubuntu release
Done Upgrade tool signature
Done Upgrade tool
Done downloading

So you’re happily developing a rails app, and for whatever reason need to restart your devel server.
And then you get this (paths removed to improve readability):

$ script/server
=> Booting Mongrel (use ’script/server webrick’ to force WEBrick)
=> Rails application starting on http://0.0.0.0:3000
=> Call with -d to detach
=> Ctrl-C to shutdown server
** Starting Mongrel listening at 0.0.0.0:3000

The SVN FAQ has an entry with the title why aren’t my repository hooks working?. It describes some debugging tips for svn hooks.
Unfortunately it does not mention a few very important SVN ‘features’:
1. stdout of all repository hooks goes to /dev/null, always
2. stderr of post-commit repository hooks goes to /dev/null, always
3. stderr of all but [...]

Xen 3.2.0

So Xen 3.2.0 was released last week.
Oddly enough there are no precompiled 64-bit binaries anymore. That does not make much sense to me - running Xen on 32 bit is just… painful. Problems with accessing ram beyond 4GB, issues with libc6, etc. On 64 bit all that stuff just works.

bluetooth on the 1420N

When I purchased my Dell Inspiron 1420N with Ubuntu pre-installed, bluetooth was not offered as an option. It seems it still is not as of today.
The machine does have a nice built-in slot and connector for a bluetooth module. It seems the Wireless 355 Bluetooth Module is the right one, even though the Inspiron 1420N [...]

Xsane works quite well, even if you want to scan a multipage document into a PDF. Just select ‘multipage’ as the target:

and then this window will pop up, where you can select an output format; the default is PDF.

I had a 17 page document to scan, which I (foolishly, perhaps) did at 150dpi. That resulted [...]

Today is Software Freedom Day! Events are being held in 90 countries, organized by 330 local teams. I’m looking forward to the Boston event this afternoon.
