Freshmeat for the Weekend 22/06

VMware Server RC 1 (Build 24927) got released! It is free, so grab a copy and give it an test drive. I just want to outline two advanced topics:

  • Linked Clones is an concept to use one basedisk for several VMs. Changes made by the VMs are written to snapshot images. That helps you to safe diskspace when using a lot of VMs. You can read more on how to do linked clones with VMware Server in the following thread on VMTN.
  • Use arbitrary block devices as Physical Disks in VMs. VMware normally allows you to use /dev/sd* and /dev/hd* devices. So you may run in to problems if you wanted to use LVM, soft-RAID (md) or things like AoE (ATA over Ethernet). vmware-bdwrapper solves such problems. Read how to get vmware-bdwrapper working with VMware Server in that thread.

But VMware Server RC1 was not the only release you should check out, get the following things as well if you are interested:

iSCSI unter Linux - das SAN für zuhause

Die Virtualisierung von Festplatten mit iSCSI ermöglicht den Aufbau von einfachen und kostengünstigen Testumgebungen. Der Vortrag stellt iSCSI im Gesamtzusammenhang mit anderen Technologien wie NFS, GNDB und VMware dar. Abgerundet wird der Vortrag mit einer Demonstration, wie sich in kurzer Zeit ein Shared Storage Cluster mit iSCSI und dem GFS (Global File System) zuhause aufbauen lässt.

Oracle Secure Enterprise Search 10g

Oracle is doing a lot of press releases at the moment. First they bought Sleepycat (Berkeley DB) and now they try to attack Google.com? I watched the demo of Oracle Secure Enterprise Search and I must admit the web interface looks very familiar to me :-).

I am wondering if that new product is somewhat related to YAPA the Oracle Text demo from OTN. May be YAPA is the predecessor of SES? A crawler/spider component could also be found as an demo on OTN called Indagine.

On the other hand, it is more likely that SES is the continuation of TripleHop MatchPoint which Oracle bought in June 2005.

Oracle Database 10g Express Edition

wow, the free Oracle starter database version - called Express Edition - has reached production state! In my opinion it has never been easier to get an working Oracle database installed on Linux. The download is just 220 MB large and you won`t belief it - it comes as an RPM package! Hey, and it already includes a nice web interface, which makes it easy to create small database driven web applications:

Oracle Express Edition - Web-Interface

You can find more information on the Oracle Database 10g Express Edition homepage.

Finally there is also a new version (1.3.21) of TOra - Toolkit For Oracle which also works quite well with the Express Edition. You can download TOra from tora.sf.net

[Update 05. Apr 2011: Please see also my new post: Oracle Database 11.2 Express Edition Beta]

22C3 is coming up

Wow, the end of 2005 is coming, so - same procedure as every year :-D
In my case that will be the 22nd Chaos Communication Congress. Just finished booking the train ticket and hotel.

22C3 Logo

The line-up of interesting talks is quite overwhelming this year. There are a lot of talks about buffer overflows and related topics - I am very curious about new approaches and developments concerning that craftwork...

The degree of collateral damage for this years congress will also be very amusing :-D. Last year we got a mass defacement for over 18.000 websites. Well nothing spectacular, but it hit the news and makes up the reputation...

If you are interested in digital life and/or computer security you may want to check out the 22C3 webblog or the schedule.

You also attend the 22C3? If you like get in touch with me... I am always happy to meet new and interesting people.
