Ubuntu Kung Fu
Prepared exclusively for Alison Tyler Download at Boykma.Com What readers are saying about Ubuntu Kung Fu Ubuntu Kung Fu is excellent. The tips are fun and the hope of discov- ering hidden gems makes it a worthwhile task. John Southern Former editor of Linux Magazine I enjoyed Ubuntu Kung Fu and learned some new things. I would rec- ommend this book—nice tips and a lot of fun to be had. Carthik Sharma Creator of the Ubuntu Blog (http://ubuntu.wordpress.com) Wow! There are some great tips here! I have used Ubuntu since April 2005, starting with version 5.04. I found much in this book to inspire me and to teach me, and it answered lingering questions I didn’t know I had. The book is a good resource that I will gladly recommend to both newcomers and veteran users. Matthew Helmke Administrator, Ubuntu Forums Ubuntu Kung Fu is a fantastic compendium of useful, uncommon Ubuntu knowledge.

Against this backdrop, this paper seeks to develop a systematic overview of open source communities and their socio-economic contexts. I begin with a recon- struction of the genesis of open source software projects and their changing relation- ships to established IT companies. -

Solaris 10 End of Life
Solaris 10 end of life Continue Oracle Solaris 10 has had an amazing OS update, including ground features such as zones (Solaris containers), FSS, Services, Dynamic Tracking (against live production operating systems without impact), and logical domains. These features have been imitated in the market (imitation is the best form of flattery!) like all good things, they have to come to an end. Sun Microsystems was acquired by Oracle and eventually, the largest OS known to the industry, needs to be updated. Oracle has set a retirement date of January 2021. Oracle indicated that Solaris 10 systems would need to raise support costs. Oracle has never provided migratory tools to facilitate migration from Solaris 10 to Solaris 11, so migration to Solaris has been slow. In September 2019, Oracle decided that extended support for Solaris 10 without an additional financial penalty would be delayed until 2024! Well its March 1 is just a reminder that Oracle Solaris 10 is getting the end of life regarding support if you accept extended support from Oracle. Combined with the fact gdpR should take effect on May 25, 2018 you want to make sure that you are either upgraded to Solaris 11.3 or have taken extended support to obtain any patches for security issues.

Software Wars, Business Strategies and IP Litigation
Software Wars, Business Strategies and IP Litigation Immediately after Oracle America filed a patent infringement suit against Google Inc. in August 2010 the trade press labelled this a “software war.” Their interest was a trial featuring Oracle’s “star” counsel David Boies. In mid-January often cited Florian Mueller of NoSoftwarePatents, wrote “Google is patently too weak to protect Android—Google’s cell phone software.”1 (On April 4 Lead bidder Google offered $900 million for Nortel’s 6,000 patents and applications. A decision is expected in June}. By the end of March he had counted 39 patent infringement suits against Google.2 Whether Oracle wins Oracle v Google or not, Oracle and IBM may become losers. It is important that Oracle not alienate the software development community or its customers as it attempts to monetise the assets from the Sun Microsystems—now Oracle America— acquisition. The Oracle v. Google complaint was carefully targeted at Google’s Android software, avoiding the appearance of monetising the Java language and platform itself. The Android software was developed as open source in conjunction with the Open Handset Alliance. Android's mobile operating system is based on a modified version of the Linux kernel, subject to Linux patents. Google published all of the computer code under an Apache Software Foundation License.3 This license is royalty-free and places no restrictions on derivative products or commercial use. Based on IDC market share estimates by the fourth quarter of 2010, Android phones had 39% of the market. An Oracle asset gained through the acquisition of Sun was the OpenOffice open-source software—one of the only remaining substantial “competitors” to Microsoft’s document processing applications. -
