Full Control in Windows 7

Salam Anak IT.
Have you ever experienced the following?:

Or maybe you can't access certain folders and files especially when you browse old harddisk which has Windows Operating System installed? Follow these simple steps.
Right click on the folder/file you want to access, then click on "Grant Admin Full Control".

A command prompt will appear showing processes take place.

Then, you are done! Easy right? But be sure your user account is part of the administrators in order to make it work.
Semoga mendapat manfaat mun inda banyak pun, sikit jadi ta =)
Sekian, wassalam.

A Different Way of Presenting

With so many things like assignments and presentations going on in Uni life, you often tend to stumble upon the thought of how to make your presentations much much more interesting. Amazingly, a few days ago, for a certain lecture, I was introduced to a new way of presenting by my fellow peers. They made their presentation very dynamic with words moving here and there.
At first, I thought they had made it from scratch using Flash but then I noticed a logo at the bottom left corner of the screen. 
Now I know I may be a little late on this, but for those who have never heard of this before, Prezi is basically a web-based presentation app launched somewhere in May 2008. So it has pretty much been around for the past 3 years or so. It's easy to access as long as you have the internet, simply go toprezi.com. The website basically looks like this

I was wow-ed by how you can just jump from word to word and zoom in and out easily with the click of a mouse. The presentation would just be on a wide canvas instead of separate slides, like on a Powerpoint presentation. However, in order to start making your own prezis you will have to sign up and upon signing up, this will be asked
In addition, you can also download prezi on your desktop, or your iPad, so that you can just work-on-the-go. Unfortunately, the creators of prezi have yet to release a prezi app for Android, but they have mentioned that they are working on it. Below is a sample of a completed prezi.
I will give further detail after I have completed experimenting with the site. That's all for now folks.

What's going on (in the background)?

When you hear your computer's fans kick in for no apparent reason there is always a good time to check up on what's going on in the background that is driving the CPU to work hard and thus kicking the fans to start in order to cool the working and heating up CPU. Or sometimes when the computer seems to be acting slow, there could be some application or process that is causing the system to slow down. It's time to take a look at the processes (not to be confused with processors) running on your system
Today's culprit is Finder, which is OS X's file explorer that you use to navigate folders in order to find / open / manage your documents and files.
Finder what are you up to using 99.2 CPU usage?
Finder what are you up to using 99.2 CPU usage?

It was using 99.2% of my CPU core's cycles. I closed the 2 Finder windows and my fans stopped in due time. The reason you want to stop this kind of behaviour is that it slows down your system and also causes a lower battery life as it is processing something in the background. I saw no reason for it to behave this way, I closed the windows. If you are encoding/rendering a video you will expect some application to be using the CPU cycles and thus closing that program will cause that action to fail, thus don't just willy nilly close any application that is using CPU cycles.
To view current CPU usage by processes
  • Mac: Open Terminal and type "top -o cpu"  (without the quotation marks) and press Enter
  • Linux: Open the Terminal / Console and type "top" and press Enter
  • Windows: Press Control + Shift + Escape > Click "Processes" tab
    Windows Task Manager - Processes Tab
    Windows Task Manager - Processes Tab
To close misbehaving applications
  • Mac & Linux: "kill -9 PID"  and if that doesn't work "sudo kill -9 PID" (PID is the number under the PID column in the "top" output)
  • Windows: select the process and click the "End Process" button
Hopefully this will help you kill some misbehaving applications and help increase your battery life when you're out and about.
