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.

Security Leftovers

  • Someone is putting lots of work into hacking Github developers [Ed: Dan Goodin doesn't know that everything is under attack and cracking attempts just about all the time?]
    Open-source developers who use Github are in the cross-hairs of advanced malware that has steal passwords, download sensitive files, take screenshots, and self-destruct when necessary.
  • Security Orchestration and Incident Response
    Technology continues to advance, and this is all a changing target. Eventually, computers will become intelligent enough to replace people at real-time incident response. My guess, though, is that computers are not going to get there by collecting enough data to be certain. More likely, they'll develop the ability to exhibit understanding and operate in a world of uncertainty. That's a much harder goal. Yes, today, this is all science fiction. But it's not stupid science fiction, and it might become reality during the lifetimes of our children. Until then, we need people in the loop. Orchestration is a way to achieve that.

Leftover: Development (Linux)

  • Swan: Better Linux on Windows
    If you are a Linux user that has to use Windows — or even a Windows user that needs some Linux support — Cygwin has long been a great tool for getting things done. It provides a nearly complete Linux toolset. It also provides almost the entire Linux API, so that anything it doesn’t supply can probably be built from source. You can even write code on Windows, compile and test it and (usually) port it over to Linux painlessly.
  • Lint for Shell Scripters
    It used to be one of the joys of writing embedded software was never having to deploy shell scripts. But now with platforms like the Raspberry Pi becoming very common, Linux shell scripts can be a big part of a system–even the whole system, in some cases. How do you know your shell script is error-free before you deploy it? Of course, nothing can catch all errors, but you might try ShellCheck.
  • Android: Enabling mainline graphics
    Android uses the HWC API to communicate with graphics hardware. This API is not supported on the mainline Linux graphics stack, but by using drm_hwcomposer as a shim it now is. The HWC (Hardware Composer) API is used by SurfaceFlinger for compositing layers to the screen. The HWC abstracts objects such as overlays and 2D blitters and helps offload some work that would normally be done with OpenGL. SurfaceFlinger on the other hand accepts buffers from multiple sources, composites them, and sends them to the display.
  • Collabora's Devs Make Android's HWC API Work in Mainline Linux Graphics Stack
    Collabora's Mark Filion informs Softpedia today about the latest work done by various Collabora developers in collaboration with Google's ChromeOS team to enable mainline graphics on Android. The latest blog post published by Collabora's Robert Foss reveals the fact that both team managed to develop a shim called drm_hwcomposer, which should enable Android's HWC (Hardware Composer) API to communicate with the graphics hardware, including Android 7.0's version 2 HWC API.
