Oracle at LinuxTag 2011 in Berlin, Germany

Linuxtag is likely one of the oldest and largest Linux/OSS events in Germany. I remember having been there to represent SuSE Linux while it still took place at the University of Kaiserslautern, using tables and chairs from the lecture rooms as exhibition stands (this must have been around 1998 or 1999). This year it will take place in Berlin again, and the session schedule looks very promising. I'll be there from Wednesday till Friday and I feel that I will have a hard time deciding which presentations I should attend...

I'll be speaking about What's new in MySQL 5.5 on Friday, 13th of May, at 15:00. If you haven't updated to MySQL 5.5 yet, stop by to hear what new …

What VMware's Cloud Foundry announcement is about

I chatted today about VMware's Cloud Foundry with Roger Bodamer, the EVP of products and technology at 10Gen. 10Gen's MongoDB is one of three back-ends (along with MySQL and Redis) supported from the start by Cloud Foundry.

An IaaS (Infrastructure as a Service) product, which hands you an emulation of bare metal where you run an appliance (which you may need to build up yourself) combining an operating system, application, and related services such as DNS, firewall, and a …

[CentOS] OpenVZ – container based virtualization quick guide. Part 2

In this guide, we will be exploring how to use the tools which come with OpenVZ and setup a internet facing container/vm. This part of the guide also assumes you have followed part 1 to setup the container already and have a working environment.

In part 1, we setup a CentOS container which we could enter/exit but we didn’t do anything else on the network. What we want to do is set it up so we have the ability to bridge our hosts’ network and define static IP for network interface.


yum install bridge-utils
