The Ultimate List of Uses for Old Computers
Are you wondering what to do with that old computer? Well, I will start by skipping the usual… I will not talk about the obvious uses which you probably already know like: “Sell it on eBay”, “Cannibalize it”, “Give it to the Kids”, “Donate it”, “Recycle it” etc. If you wanted to do any of those you wouldn’t be reading this article in the first place, would you? Or other uses that are simply not practical for 99.9% of us… Like building a cluster… That is, if you have more than one old pc, and are prepared to spend more on electricity than what these computers are worth. File server: I would venture to say that this is easily the most popular use for an old computer now days. Build your own TiVo: I am sure many of you have wondered, why should we have to pay a monthly fee to record a program we are already paying for. Build your own SLINGBOX: Want to watch programs at work? Build your own CCTV (Security Camera) System: Build a Home Automation Server: Build your own Arcade Console:
Baking Pi - Operating Systems Development
This course has not yet been updated to work with the Raspberry Pi models B+ and A+. Some elements may not work, in particular the first few lessons about the LED. It has also not been updated for Raspberry Pi v2. Welcome to Baking Pi: Operating Systems Development! You can now help contribute to this tutorial on GitHub. This website is here to guide you through the process of developing very basic operating systems on the Raspberry Pi! This course takes you through the basics of operating systems development in assembly code. Rather than leading the reader through the full details of creating an Operating System, these tutorials focus on achieving a few common tasks separately. 1 Requirements 1.1 Hardware In order to complete this course you will need a Raspberry Pi with an SD card and power supply. 1.2 Software In terms of software, you require a GNU compiler toolchain that targets ARMv6 processors. 2 Lessons

How to Build a Hackintosh Mac and Install OS X in Eight Easy Steps
@douglobue: Apple doesn't always have the hardware options you want, and if they do, as with windows computers, building your own is almost always cheaper. Plus, as you said, it's fun to DIY. @douglobue: You're not going to get the same hardware for the price, but if you need a monitor, that's certainly an extra price. Personally, I wanted a powerful machine I can open up, add things to, and control. Mac Pro's are insanely expensive; Hackintosh machines are not, but can be very, very powerful. And yeah, DIY is part of the fun. :) @douglobue: i just priced out all the parts to do an 8-core i7 @ 3.06ghz. with 8gb ram, and a 1tb drive. for under $1800. an imac, at that price range, comes with an i3 with 4 gb of ram. @douglobue: Core i7 is your answer, you have to be geek enough to understand.
What does everyone think of this article?
I have a question:
In a datacenter for a big website company like Google, do they depend completely on clustering to build their computer infrastructure. Also anybody has any idea about their clustering software that they use. I know they use Hadoop, but they run than on top of already clustered machines running lunix. Hadoop works on clustered machines, but doesn't perform clustering. Any thoughts about that? by khalaf Feb 4
