You would be thinking of a quantum computer. Relatively few and simple concepts from quantum mechanics are needed to make quantum computers a possibility. The subtlety has been in learning to manipulate these concepts. Is such a computer an inevitability or will it be too ...

Where Are The Linux Workplaces?
When I was in college, lower level CS course assignments were done in DOS PC's networked through Novell Netware. Once a student got to take higher level courses, he/she was given an account into one of the department's SunOS Unix servers. Most students from basic courses suffered from "Unix envy", the Sun boxes were perceived as being much more powerful than the humble PC's. As a I entered the workplace, I brought my college perception that Unix workstations are more powerful ...

How to Buy a LCD Monitor
I had been salivating for about an year, desperately wanting a LCD monitor for my computer but the prices were crazy so I decided to wait a while. A couple of months ago while I was in Dubai I decided to buy a LCD monitor because the prices had dropped by then. I went in search of a 17’’ monitor but ended up buying a 19’’ screen. This was because, for the money I spent in Dubai for 19’’, I was getting 17’’ in India. And as we all know...size DOES matter....at least in ...
Hard Drive Cooling for 10 Cents
I have purchased almost every hard drive cooling device on the market, some costing as much as $50 or more. I have systems that place fans in front of the drive that suck air from the outside, and fans that mount underneath. The problem with these setups are that they tend to be expensive, the airflow tends to be quite low, and in general they just don't cool down the drives by more than 1 - 5 degrees. I even own one that claims an 80cfm airflow. But alas I was never satisfied with any ...

Reasoning Without Data
Some believe that there is no point in reasoning without data. Others cannot accept this and instead get by on reasoning based on intuition and even simply the belief that they should instinctively know. Many of the greatest theories in the world have come thru very little data or none at all. So many of these theories of past periods are later proven with data in subsequent future periods, thus proving you can reason without data.
Trouble-shooting mouse problems
Question : I have a problem with my mouse. This usually happens when I leave the PC idle for more than five minutes. The mouse goes berserk whenever I try clicking it. It would point to another icon and then run the related program. Although I press the "Escape" key, I still could not control it. I have to wait for about five minutes for it to settle down. The problem would recur whenever I leave it for a while.

Network Wiring Standards
There are two wiring standards for network cabling. T568A and T568B are the two standards for the RJ-45 or 8-position modular connector, permitted under the TIA/EIA-568-A wiring standards document. The only difference between T568A and T568B (also known as Weco, AT&T 258A) is that the orange and green wire pairs (pairs two and three) are interchanged. How to decide which wiring pattern to use:
What Are Network Patch Panels
Patch panels are used as the central point in a network where all the network cables terminate. It is the grand central station of the network. Networks that use patch panels (and almost all modern networks use this technology) are consider “star-networks” or they use the term “star-topology.” This is because if you look at a drawing of your network, all the network nodes (nodes are end-points on the network and include things like computers and printer) all connect back to the ...
