Oracle Buys Ksplice for Rapid Linux Updates

Make no mistake about it, Oracle is serious about its Linux business. Today Oracle announced what I consider to be a significant addition to that business with the acquisition of Ksplice. Ksplice is this really neat tech that lets Linux admins 'hot patch' that is patch an in-use system without the need for a reboot. For a mission critical system, that's a big deal. It means that Oracle now potentially has a feature that other distros do not. No, this doesn't mean that Oracle is going to automatically block Ksplice from supporting other distros. BUT I do expect that it will be more optimized and integrated with Oracle Linux.

  • Secure Hosting Directory; By Terry Newbury (Posted by abefroman on Jul 21, 2011 5:19 PM CST)
  • Story Type: Editorial; Groups: Linux, PHP
There seems to be a belief these days that complying with the PCI standard is bound to be expensive and difficult to put in place. Actually if you have a Linux system, this doesn't have to be the case at all. However, while a Linux system is generally thought to be better for security, nevertheless, there are weaknesses to Linux that could be exploited by a potential hacker, and knowing these weaknesses and knowing how to deal with these weaknesses can be crucial to the server administrator who wants to ensure that his systems and networks are PCI complaint.

This week at LWN: Copyright, copyleft, and culture

Nina Paley has certainly stirred things up with her recent "rantifesto" on free culture and free software. It has spawned numerous responses on various blogs, both from supporters and those who disagree with her contention that the Free Software Foundation (FSF) is being hypocritical in its licensing of its web pages and other non-software works. For some people it is a bit galling to see an organization that is set up to ensure the right to create and distribute derivative works (subject to some conditions, of course) of software, be so steadfast in its refusal to apply those same freedoms to text and other works.

How To Run Your Own DNS Servers With ISPConfig 3 (Debian Squeeze)

  • HowtoForge; By Falko Timme (Posted by falko on Jul 21, 2011 11:05 AM CST)
  • Story Type: Tutorial; Groups: Debian
This tutorial shows how you can run your own DNS servers (primary and secondary) with ISPConfig 3. To do this, you need two servers with two different public IP addresses and with ISPConfig 3 installed. I will use Debian Squeeze for both DNS servers here to demonstrate the base system setup process and ISPConfig 3 installation, but once you have ISPConfig 3 installed on your servers, the configuration inside ISPConfig 3 is identical, no matter what distribution you use.
