Auf chaosradio.ccc.de gibt es einen netten Podcast mit Elisa Jasinska (AMS-IX) und Christian Kaufmann (Akamai) zum Thema Peering, Transit, Internet Exchanges, AS, BGP4 und all das, was das Internet antreibt. Akamai ist übrigens derzeit der einzige CDN Anbieter, der kostenfrei am Berliner Internet Exchange (BCIX) mit anderen ISPs Daten austauscht. Fragt euren Provider, ob er schon am BCIX mit Akamai peert, damit auch Ihr die möglichst kleinste Antwortszeit auf die Webseiten der Kunden von Akamai wie apple.com, myspace.com, mtv.com, maps.nokia.com, tagesschau.de usw. von Berlin aus bekommt.
Habt Spaß bei zwei Stunden Chaosradio mit Elisa und Christian!

CloudCamp Berlin 2009 has still free seats, register here, it’s free.
Solaris 10 05/09 or also called Solaris 10 Update 7 release seems to available within April / May 2009. Hope to see Intel Nehalem optimizations in S10U7 as these new Intel CPUs will also be available at this date.
Wishing everyone a happy, healthy and successful new year.
Flock 1.0 Browser is ready to download. If you’re a flickr/twitter/facebook user, you’d love using flock. No Solaris Version, yet.
As mentioned, Barracuda Networks seems to have no interest to support their own Barracuda Spamfirewall plugin for Thunderbird. The problem is, that it doesn’t work since Thunderbird Version 2.0.0.4. Here a hack from the user forum to make the plugin work with Thunderbird 2.0.0.4.
If you unzip the .xpi file (it’s really a zip file, just with an xpi extension), and edit the “install.rdf” XML file, you can update the maxVersion value to a number the same as or greater (for example from 2.0 to 2.2) than the version of Thunderbird you’re using, and then re-zip the files into a new zip file with a name ending in “.xpi”. Reinstall in Thunderbird and everything is fine.
I don’t pimp Pixelpark products much in this blog, but today I’ll do. Over the last years, we used to host Web portals in our datacenter for customer on a Solaris based serverfarm called gridpark. Since 2005 we run Solaris 10 with Solaris zones on Sun Sparc, Sun Coolthreads and AMD Opteron processors, dependent on the solution for the customer. Besides of the main gridpark platform, there are also customers on Linux, Windows 2003 and VMWARE on Dell and IBM Server Hardware. Most of these dedicated solutions are based on standard rackmount servers like Dell 2850, Sun X4100, X4200, X4600, T2000, V240 and so on. We looked at a couple of Blade platforms in the past, but almost all of them had a couple of disadvantages for us. But there’s a new Blade platform now, the Sun Blade 6000 familiy.
Besides the 10 slot chassis, there are are a couple of different server modules available for the Sun Blade 6000 modular system today:
- T6300: 1 socket Sun UltraSparc T1, almost the same as the Sun T2000
- X6220: 2 socket AMD Opteron 2000 Series, dual core, looks like the X4100 with more memory slots
- X6250: 2 socket Intel Clovertown Series, dual and quad core
That means, we have the choice today to decide on which CPU platform to run web portals best. Looking at SPECweb2006 and SPECjAPPServer2004 results to compare this three CPU platforms, you will soon see the winner: The Intel Clovertown series seems to outperform the AMD Opteron 2000 Series and the Sun UltraSparc T1 CPU in these benchmarks. If you look at database performance (mysql and postgresql), tweakers.net published their experience comparing a Sun X4600 8 socket dual core Opteron Server with a Intel Cloverton X5355 2 socket quad core server.
The conclusion of tweakers.net is, that for typical web (2.0) workloads (SPECweb, SPECjbb, small databases) the Intel Clovertown CPUs has a very interesting price/performance ratio.
And what does this mean for project gridpark: It’s a big advantage for us, to have a the possibility to buy the Intel Clovertown based servers from Sun for the Sun Blade 6000 plattform and to have Sun Solaris 10 support as well as already optimized Sun Studio 12 compilers.
A very nice feature offered by Barracuda Networks Spam Firewall is the Thunderbird plugin to classify mails as spam within Thunderbird. But after upgrading Thunderbird to 2.0.0.4, the plugin stops working. Barracuda Networks Support answer to this : Unfortunately we do not have a new version of the Thunderbird plugin and we currently do not have an ETA on when a new plugin will be available. I apologize for this inconvenience.
One solution might be to build as custom Thunderbird filter, mentioned here.
