href="">apt-get command</a> line options. After each upgrade you need to reboot the server. Ksplice service allows you to skip reboot step and apply hotfixes to kernel without rebooting the server. In this post, I will cover a quick installation of Ksplice for RHEL 5.x and try to find out if service is worth every penny. ]]></description> <wfw:commentRss>http://www.cyberciti.biz/tips/debian-centos-redhat-hotfix-patch-linux-kernel.html/feed</wfw:commentRss> <slash:comments>10</slash:comments> </item> <item><title>10 Greatest Open Source Software Of 2009</title><link>http://www.cyberciti.biz/tips/10-greatest-open-source-software-of-2009.html</link> <comments>http://www.cyberciti.biz/tips/10-greatest-open-source-software-of-2009.html#comments</comments> <pubDate>Thu, 24 Dec 2009 19:49:11 +0000</pubDate> <dc:creator>Vivek Gite</dc:creator> <category><![CDATA[Software]]></category> <category><![CDATA[application software]]></category> <category><![CDATA[Linux]]></category> <category><![CDATA[Mac Software]]></category> <category><![CDATA[windows software]]></category> <guid

And they said, "Oh, gosh, they're, like, four or five times higher than what we're seeing on other PCs that have Windows." I said, "Exactly." So let's do the TCO story. Let's talk to customers. And you can't find a retailer - I challenge you to find a retailer who wants to sell Linux on these netbooks, because the returns are bad. The customer complaints are bad. And our ability to really showcase the value proposition with Windows has never been greater and was never tested more than it was with this particular product. But we've made great progress there, but the up-sell opportunities with Windows 7, because it runs so well on these low-end laptops, is going to be tremendous for us.</blockquote>]]></description> <wfw:commentRss>http://www.cyberciti.biz/tips/dell-says-linux-netbook-returns-a-non-issue.html/feed</wfw:commentRss> <slash:comments>30</slash:comments> </item> <item><title>How A Microsoft Veteran Learned To Love Linux And Why It Matters</title><link>http://www.cyberciti.biz/tips/learned-to-love-linux-and-why-it-matters.html</link> <comments>http://www.cyberciti.biz/tips/learned-to-love-linux-and-why-it-matters.html#comments</comments> <pubDate>Thu, 18 Jun 2009 22:50:37 +0000</pubDate> <dc:creator>Vivek Gite</dc:creator> <category><![CDATA[Linux]]></category> <category><![CDATA[Windows]]></category> <category><![CDATA[Windows server]]></category> <category><![CDATA[windows vista]]></category> <category><![CDATA[airplane]]></category> <category><![CDATA[dual boot]]></category> <category><![CDATA[fedora]]></category> <category><![CDATA[free software]]></category> <category><![CDATA[graphical installer]]></category> <category><![CDATA[keith curtis]]></category> <category><![CDATA[microsoft]]></category> <category><![CDATA[microsoft employee]]></category> <category><![CDATA[microsoft veteran]]></category> <category><![CDATA[minor miracle]]></category> <category><![CDATA[ntfs partition]]></category> <category><![CDATA[software wars]]></category> <guid

/> "After The Software Wars", is a new book in which former Microsoft employee Keith Curtis explores the worlds of proprietary and free software.  Quoting from the article:<blockquote>While I came to not be all that thrilled with Fedora itself, I was floored merely by the installation process. It contained a graphical installer that ran all the way to completion, it resized my NTFS partition -- which I considered a minor miracle, setup dual boot, and actually did boot, and let me surf the Web. I didn't have a clue what to do next, but the mere fact that this all worked told me more about the potential of Linux than anything I had read so far. You cannot, by accident, build an airplane that actually flies.</blockquote> <br

From the article:<blockquote>Despite being a very important part of any operating system, file systems tend to get little attention. Linux has three editions for Linux Device Drivers, another three for Understanding the Linux Kernel and two for Linux Kernel Development. The first is a detail analysis of one particular Linux Kernel tree and the second is a shorter one done over a large number of file systems from Linux Kernel 2.6.0 to 2.6.29. After that there is a small section  that shows some aspects of the BSD family. After conclusions there is an appendix consisting of three things: the first one explains how the file systems for Linux were compiled, the second one shows timelines for the releases of Linux Kernel, FreeBSD, NetBSD and OpenBSD; the last is a detailed map of the external symbols of the kernel modules analyzed in the second section.</blockquote> <br
