China to develop own OS

By October, China might have its own Operating system to compete with the likes of Microsoft, Apple and Google. The operating will first be tested on computers and latter a mobile version will be developed. This also follows the recent ban of the use of Windows 8 on government computers.

I hope Africa will also be looking forward one day to develop its own operating system.

Windows XP and Office 2003 user support to end very soon

After 12 years, support for Windows XP will end on April 8, 2014. There will be no more security updates or technical support for the Windows XP operating system. It is very important that customers and partners migrate to a modern operating system such as Windows 8.1. Customers moving to a modern operating system will benefit from dramatically enhanced security, broad device choice for a mobile workforce, higher user productivity, and a lower total cost of ownership through improved management capabilities.

Support for Office 2003 also ends on April 8, 2014.

Showing hidden files on a pen drive using the command prompt

Sometimes we store files on a pen drive but windows fails to display them. What annoys the most is that when you check for the properties of the drive, it will show you that some disk space has been used. So how do you show these hidden files!
1. Insert your pen drive into the USB port of your computer
2. Find the drive letter of your connected pen drive e.g "I"
3. Open the command prompt (Type cmd at the search bar of the start menu and press enter)
4. type the following command: attrib -s -h /s /d *.*
5. Press enter and you are done

type "attrib help" (minus quotes) on the command line for explanation of the attribute command

From PDF to Videos

Many people would love to learn programming in the simplest ways Possible, but they always need help to learn from PDFs.

Since most of you enjoy watching rather than reading then, programming can become your favorite if you learn by use of Video tutorials; you can find lovely tutorials on the website below, and you don't need to pay a single penny.

User Mode Vs Kernel Mode

All programs or processes when running are executed in User mode. Processes do not interact directly with the kernel but they just give instructions in form of system calls and the kernel mode will take care of the rest.

Switching to kernel mode requires one of these to happen, an interrupt, a trap and  I/O or event occurrence.
The kernel mode responds to the request for example handling of device drivers, memory allocation and others which we refer to as privileged instructions, and the process is switched back to user mode where we find less privileged instructions.


"When the computer boots up, Windows calls the KERNEL, the

main kernel-mode program that allows all the other programs
to run, even the user-mode programs".

Operating System Programming

It has always been a challenge to know how the OS was built. The release of the Win 32 bit OS was a basis for the development of win 64 bit OS. The C-language is a basis for many operating systems. You can also program your OS or even learn how Windows was built. for more info visit "http://www.tenouk.com/cnwin32tutorials.html"

UNIX Operating System

Many people have a lot of questions concerning what UNIX is, most OS's falling in this category were developed using the C-language.



"Since PDP-11 Unix became operational in February, 1971, over 600 installations have been put into service. Most of them are engaged in applications such as computer science education, the preparation and formatting of documents and other textual material, the collection and processing of trouble data from various switching machines within the Bell System, and recording and checking telephone service orders. Our own installation is used mainly for research in operating systems, languages, computer networks, and other topics in computer science, and also for document preparation."

And the name UNIX, In 1970 Peter Neumann coined the project name Unics (UNiplexed Information and Computing Service) as a pun on Multics, (Multiplexing Information and Computer Services)^[7]. Unics could eventually support multiple simultaneous users, and it was renamed Unix.

Mobile networks

Just look at the Motorolla dynatac phone which was released in 1973. It was the first cellular telephone with a battery that wold only last an hour of talktime. I think we are about to back to that generation in terms of size because phones have become big again.
