daystar_machspeed.gifRecently I had the opportunity to upgrade my PowerBook G4 1.5GHz to a 2.0GHz Freescale 7447A CPU. Daystar Technology based in Georgia offers a MAChSpeed upgrade service to PowerBook owners like me who are wanting that extra power to run Logic Pro and other CPU intensive applications like Final Cut Pro. I took the plunge in the name of technology and sent my PowerBook in a custom box provided free by Daystar to its customers.

Unraveling the Mac OS X Microkernel Myth

mk.jpgAccording to proponents of this myth, Mac OS X is in grave danger because it has a microkernel and Linux doesn’t. They’re wrong; here’s why.
The Myth Weavers
This myth is of the wishful thinking type, making it more of an irritating distraction from reality than devious misinformation, but it’s also used in fanboyism that borders on FUD.
Some Linux advocates insist that nothing compares to the pure genius of Linux, so everything should just adopt Linux. Some Mac OS X users worry that there’s something evil lurking in their system that makes that dreaded beach ball spin; perhaps it’s a microkernel, and perhaps replacing it with Linux (which doesn’t even have a beach ball!) is the answer?
What is a Kernel?
The Unix Kernel is the master control program which governs all other programs, schedules access to hardware, and manages the file system and security model. The name kernel differentiates the core system (which runs as the root process with special privileges) from everything else on the system (which runs under restricted user accounts). Everything outside of the kernel space is called the userland.
In the natural development of Unix, the kernel began to grow rapidly. For example, Berkeley’s famous contribution to Unix was a fully functional TCP/IP networking stack. A rapid influx of other new functionality in the core kernel space has resulted in modern versions of Unix (and Linux, which is essentially a clean room rewrite of Unix) having 2-3 million lines of code in their kernel alone.

More on the MacBook (Pictures)

After yesterday’s piece on the MacBook’s HDD access door I have a little more feedback on the MacBook.
The glossy screen is nice, but more difficult to read from the side. I prefer the satin screen of the MacBook Pro. The shell of the machine is a very similar texture to the older Pismo models, but a more deeper black color.
The MacBook now opens and closes without a button latch and no longer has a metal hook to keep it closed, it’s all magnetic. There’s an indentation in the front where you put your finger allowing you to pry the screen up.
The sleep light is in the front right corner and is nearly invisible when not on.
The weird thing is the new style keyboard: rather than a one-piece keyboard which attaches to the top of the laptop, the MacBook now has a top case that completely covers the top of the laptop and the keys.
