Ubuntu 10.10 vs. Mac OS X 10.6.5: A Competitive Race

We began our tests of this new Mac Book Pro last week by starting out with looking at the power consumption between Mac OS X and Linux where we found that Apple's operating system generally consumed less power on their own hardware than with Ubuntu 10.10 and the Linux 2.6.35 kernel, but that isn't to a huge surprise. With today's cross-platform tests, we are looking at the performance for OpenGL, OpenCL, CPU, and disk performance, among other areas.

The Apple Mac-F22586C8 being used boasts an Intel Core i5 520M processor clocked at 2.40GHz, 4GB of DDR3-1066MHz memory, a 320GB Hitachi HTS54503 SATA 5400RPM hard drive, and a NVIDIA GeForce GT 330M (GT216) 256MB graphics processor. The Mac OS X 10.6.5 release was used with its 10.5.0 kernel, X.Org Server 1.4.2-apple56, Apple's NVIDIA graphics driver, the Journaled HFS+ file-system, and Xcode 3.2.5 that provides GCC 4.2.1 and Clang. On the Linux side was Ubuntu 10.10 "Maverick Meerkat" with the Linux 2.6.35-22-generic kernel, X.Org Server 1.9.0, the NVIDIA 260.19.21 display driver providing OpenGL 3.3.0, GCC 4.4.5, GNOME 2.32.0 desktop, and an EXT4 file-system.

As the Phoronix Test Suite builds many of its tests from source, with this article we compared the results of both Mac OS X 10.6.5 and Ubuntu 10.10 when using their stock compilers (as found in the latest version of Xcode for Mac OS X and within the Maverick package repository for Ubuntu 10.10) as well as when building self-hosting versions of GCC 4.5.1 under each operating system. Aside from this, as usual, each operating system was tested in its stock configuration.

Open Source Software A Core Competency For Effective Tech M&A

Imagine your company just acquired its competitor for $100 million. Now imagine the company’s most important asset – its proprietary software – is subject to third-party license conditions that require the proprietary software to be distributed free of charge or in source code form. Or, imagine these license conditions are discovered late in the diligence process, and the cost to replace the offending third-party software will costs tens of thousands of dollars and take months to remediate. Both scenarios exemplify the acute, distinct and often overlooked risks inherent to the commercial use of open source software. An effective tech M&A attorney must appreciate these risks and be prepared to take the steps necessary to mitigate or eliminate them. Over the past decade, open source software has become a mainstay in the technology community. Since its beginnings, open source software has always been viewed as a way to save money and jumpstart development projects, but it is increasingly being looked to for its quality solutions and operational advantages. Today, only a fraction of technology companies do not use open source software in any way. For most of the rest, it is mission critical. Read more
