		<title>Ideas page updated</title>
		<description><![CDATA[I updated my ideas page. I added an entry about using compressed air to automatically remove snow (or similar) from solar cells, and an entry about maybe using heat from thermal solar cells to generate electricity at home. I also updated the entry for non-optimal weather optimized solar cells with a link to a company [...]]]></description>

		<title>Google’s new RE engine</title>
		<description><![CDATA[I stumbled over Google’s new RE engine. Unfortunately it is not handling backreferences, so it is not a drop-in replacement for the regular expressions code in FreeBSD. It has a POSIX mode, but this only seems to be enough for the egrep syntax. For people which need backreferences, they refer to the Google Chrome’s RE [...]]]></description>

		<title>Contacted by a lawyer regarding MP3</title>
		<description><![CDATA[A while ago (end of August 2009) I was contacted by a lawyer because of my participation in the LAME-project. It was about the MP3-patents. They searched an expert witness for a case.
I had the impression that it is about the invalidation of at least parts of one of the patents. Maybe they have a [...]]]></description>

		<title>Making ZFS faster…</title>
		<description><![CDATA[Currently I play a little bit around with my ZFS setup. I want to make it faster, but I do not want to spend a lot of money.
The disks are connected to an ICH 5 controller, so an obvious improvement would be to either buy a controller for the PCI slot which is able to [...]]]></description>

		<title>Showing off some numbers…</title>
		<description><![CDATA[At work we have some performance problems.
One application (not off-the-shelf software) is not performing good. The problem is that the design of the application is far from good (auto-commit is used, and the Oracle DB is doing too much writes for what the application is supposed to do because of this). During helping our DBAs [...]]]></description>

		<title>Debugging lang/mono — 2nd round</title>
		<description><![CDATA[Today I had again some energy to look at why mono fails to build on FreeBSD–current.
I decided to do a debug-build of mono. This did not work initially, I had to produce some patches.  
Does this mean nobody is doing debug builds of mono on FreeBSD?
I have to say, this experience with lang/mono is [...]]]></description>

		<title>Mono build problems on FreeBSD-current</title>
		<description><![CDATA[I try to build mono on FreeBSD–current (it is a dependency of some GNOME program). Unfortunately this does not work correctly.
What I see are hangs of the build. If I stop the build when it hangs and restart it, it will continue and succeed to process the build steps a little bit further, but then [...]]]></description>

		<title>Firefox 3.6, finally delivering a sane proxy handling</title>
		<description><![CDATA[At work we have to use a proxy which requires authorization. With previous versions (firefox 3.0.x and 3.5.y for each valid x and y) I had the problem that each tab requested to enter the master password when starting firefox, to be able to fill in the proxy-auth data (shortcut: fill in only the first [...]]]></description>

		<title>Improving the order of directories to backup in tarsnap</title>
		<description><![CDATA[I experimented a little bit with the order of directories to backup in tarsnap.
Currently I use the following sorting algorithm:

least frequently changed directory-trees first
Every change — even in meta-data — will affect the following data, as tarsnap is doing the de-duplication in fixed-width blocks (AFAIR 64k).
for those directory-trees which change with the same frequency: list [...]]]></description>

		<title>Stability problems solved (hardware problem)</title>
		<description><![CDATA[After putting the disks of the 7-stable system which exhibited stability problems into a completely different system (it is a rented root-server, not our own hardware), the system now survived more than a day (and still no trace of problems) with the UFS setup. Previously it would crash after some minutes.
The ZFS setup with the [...]]]></description>
