The Rise of Multicore

Electronic Chip
Multicore CPUs are the latest computer performance optimizations to go mainstream.  Most computers sold today (netbooks excluded) have at least dual core processors.  Some consumer desktops have up to 8 cores on a CPU.  There's no doubt that future computers will see many times the number processing cores seen on the typical desktop today.  But to understand why this trend is occurring, we must first understand why chip makers turned to multicore CPUs to drive performance.

Throughout the 1990's and into the early part of the 2000's single

Tethering Your Mac to a Blackberry (Bold 9700) on T-Mobile

Blackberry Bold 9700
Ever since I got my Blackberry Bold 9700 I wanted to tether it to my MacBook Pro.  For those of you who don't know what tethering is, it's when you connect your computer with your phone so that you can use your phone's data connection to access the internet on your computer.  Tethering is by no means a real substitute for Wifi.  But when Wifi isn't available, tethering is a great way to get on the internet.  This post details how to set up tethering between a Mac (OSX 10.6 Snow Leopard) and a Blackberry (Bold 9700) on T-Mobile's network.

The Myth About GHz

Electronic Chip
Typically when people I talk to discuss how 'fast' a computer is, they reference clock speed.  A common question is "how many GHz does your computer have?"  But clock speed is only one piece of what determines how 'fast' a computer is.

I am typing this post on a computer that has a 2.53GHz processor.  In the next room I have a computer with a 3.2GHz processor.  Guess which one is faster?  I'll give you a hint, it's not the computer with the 3.2GHz processor.

Why Do You Care About 64-Bit?

Electronic Chip
Simply put, 64-bit computers have the potential to be much faster than 32-bit computers. Not only can 64-bit computers process more per clock tick, they also have the potential to put more data in memory.

32-bit hardware can physically support 32-bit word instructions and addresses. In 32-bit hardware, this limitation exists because 32 pins are used as instruction inputs into the CPU. For this reason, 32-bit computers can only address up to 232 bits of memory (4GB) and they can only crunch up to 32-bits of data at a time. So, 4GB is

Using Apple Time Machine with FreeNAS

page 1 · 2 · 3 · 4

If you are like me then you don't want to shell out a ton of money for Apple's Time Capsule and you want redundant network storage that works with Time Machine. This post details how to setup Time Machine on your Mac (OS X 10.6 Snow Leopard) so that it works with FreeNAS (version 0.7).

FreeNAS (link) is an open source Network Attached Storage operating system based on FreeBSD. It supports a wide variety of services, including AFP and SSH (it also supports Samba for those of you who are Windows users). FreeNAS also works very well

Attaching Time Machine to FreeNAS

By default, Time Machine does not attach to networked storage (other than Time Capsule, of course). Fortunately, it is very simple to change that default setting. First, ensure that Time Machine is turned off (System Preferences->Time Machine). Next, open a terminal window on your Mac and execute the following command.

Configuring Storage on FreeNAS

After FreeNAS has successfully been installed, upon system startup the IP address of the NAS Server will be displayed on the screen. Open a browser and type http://<Your FreeNas IP Address> in the address bar. When prompted with a login screen, type admin for the username and freenas for the password.
