Show All Files

If you have fallen into the predicament of being unable to show all (hidden) files in the computer. If your question is how to show all files or my hidden files don't show. Then you may continue reading below.

This virus (or evil program whatever you might like to call it) is quite frequently found in the computers of  universities' labs. What it does is that, it deprives you of the right to show all files using the folder options. You might also use google to find other ways to correct this problem only if the solution provided here doesn't work, but as far as I'm concerned the following three methods should definitely suffice in solving this issue.

Method 1:

Open registry editor (the registry editor can be found in the WINDOWS folder under the name 'regedit', or alternaively you can type 'regedit' in the run command found in the start menu, you can also make the run dialog box appear by pressing 'Windows+R' keys together) & go to the following key (location):

In the right hand area, double click - Hidden - and change the value to 1.

Now it's all done. Check it in your tools menu if the changes have taken effect.

Method 2:

1. Find the key (location):

2. Look at the "CheckedValue" key, This should be a DWORD key. If it isn't, delete the key.

3. Create a new key called "CheckedValue" as a DWORD (hexadecimal) with a value of 1.

4. The "Show hidden files & folders" check box should now work normally.

Method 3:

If none of the above methods work, please Use the Smart Virus Remover (625.9 KiB):

Using this Virus Remover, restore your Windows settings and your show hidden files and folders will be set to default.

Final Year Project (FYP) Website

I have received some queries relating to the FYP website links, it's given as follows:

The FYP committee also used the google's site to host the FYP anouncements, but left it hanging in the middle without updating it, its link is given below:

They may even decide to change the links of FYP anouncement for the upcoming new FYP batches.

Computer Security Lectures

There are a total of 14 lectures of Computer Security, though lectures are numbered to sixteen - lectures 8 and 13 don't exist.

These lectures were taught and conducted by teachers:
  1. Najm-ul-Islam Farooqui
  2. Ibrahim Muhammad Hussain
This course outline is subject to be affective for batch 2006, i.e. it may or may not change for others:
Computer Security Course Outline
Lecture one consists of introduction, history, background and issues of computer security to give you a head start for the rest of the course:
Computer Security Lecture 01

Lecture two is dedicated to the basic and introductory level of cryptology and all that is there in it, focussing mainly on classical encryption algorithms:
Computer Security Lecture 02

This lecture emphasizes only Simplified Data Encryption Standard (S-DES) which is used to get you familiar with the current computer security standards at a beginner's level:
Computer Security Lecture 03

After S-DES comes DES (i.e. without the S) for in-depth view of its algo. which has been a current standard only not too long ago and has only been replaced by new standards in the late 1990's:
Computer Security Lecture 04

A very short chapter (though article is more suitable for calling it) that only focuses on differenciating between Differential and Linear Cryptanalysis:
Computer Security Lecture 05

International Data Encryption Algorithm (IDEA) is another, new age, defacto algorithm to which this lecture is dedicated:
Computer Security Lecture 06

Though IDEA is defecto standard, this lecture introduces you to the Advance Encryption Standard (AES), the accepted standard, and teaches you substition, S-Box, Mix-Columns, Add Round Key and all etc.:
Computer Security Lecture 07

To give you a clear and elaborate understanding about the working of AES rounds, view the following animation. Change the file extention to .exe before opening the file.

An another short lecture (or rather topic) introducing to you the number theory; Primes numbers, Relatively prime numbers, GCD (greatest common divisor), Fermat's Theorem and Primitive roots:
Computer Security Lecture 09

Elaboration of  Public Key Cryptography and RSA with all the working and logic to get you at the end of understanding the Asymmetric algorithms:
Computer Security Lecture 10

Cryptography in connection to Network Security is the objective of this lecture, and also outlines Diffie-Hellman Key-Exchange protocol:
Computer Security Lecture 11

Message Authentication and Hash Functions are the main ingredients of this lectue, includes Data Authentication Algorithm (DAA):
Computer Security Lecture 12

This lecture teaches you the Digital Signatures' properties, techniques and types (i) RSA approach  (ii) DSS approach:
Computer Security Lecture 14

Email security - Pretty Good Privacy (PGP) is discussed in this chapter which is pretty much all the way theory:
Computer Security Lecture 15

IPSec (IP Security) is another theoritical lecture, includes topics of transport and tunnel mode of operations, Authentication Header (AH) and Encapsulatin Security Payload (ESP):
Computer Security Lecture 16

Lecture of  Firewall was not included slides were made available for our own refference and good:

Communication Skills - Dropped out of Curriculum

It has been quite some time that the dispute over the matter of excluding the subject of communication skills out of the curriculum has finally been resolved, now, but not for the better.

Why? Because, simply put it this way, I was surprised that once after the subject has been declared in the curriculum present in prospectus of the university (SSUET), it can be removed. I was straight under the impression that once enrolled with the commitment of the prospectus, niether of the party is allowed to change their course of action, otherwise it would in violation with Higher Education Commission (HEC) & Pakistan Engineering Council (PEC) would not approve of it.

But now it seems like the hold of either of the group HEC or PEC is rather lethargic, and pays no heed to what are the current issues in our educational sector. With some minor issues as these (by the way it is not at all a minor case), you can expect these institution to overlook these hindrances, considering the fact that they have the responsibility of correcting the national infrastructure of Pakistan by imposing strict rules in their line of duties.

Home Education - Today's School Environment Spoils the Moral Integrity

From the day your child was you have been home educating - assisting them in their quest for knowledge of the world around them, answering their questions, teaching them to walk and talk. You have already done the hard stuff, and without a curriculum. In fact, if you truthfully look back at this stage, you yourself have not had much of a hand in all the wonderful things your child has accomplished. Our children are born with the ability to teach themselves everything they need to know about surviving in the world they live in, and they do it well. School interrupts this natural flow of learning and eventually kills it. If you leave children alone and just provide enough resources, encouragement and a caring environment, that is all you will ever need. Trust them and they will get the job done.

Home school is an option open to families in Australia and often the decision to home educate your child is made well after your child has started school. Schools are a fairly recent invention of man as they have only been around for about 150 years or so. Before that, parents always taught their children at home, and it was a natural part of life. Going to school is not the natural way for a child to learn and many children struggle with the concept of school. As a result, parents often see a change for the worse in their children. They become unhappy, angry little people unable to communicate with parents and siblings as they once did.

An Australian lecturer in education, who has been researching home education for ten years, has found that children who have had structured lessons at home as well as children who had absolutely no structure at home have both turned out to be socially and academically ahead of schooled peers. The only drawback that he found in the ten years of study was the lost wages of one parent.

Children do not need to be placed in artificial situations so that they can 'become socialised'. Socialization forced upon children in schools and playgrounds is not true socialization. Real socialization happens all the time, every minute of the day with parents, siblings, shopkeepers, in the park and best of all, children with themselves and their dreams. It happens all the time and we do not need to set it up. The type of socialization that does happen in the schoolyard is not the type most of us want for our children; the bullying and the peer pressure and the bad language, and children that grow up in charge of their own socialization grow strong and confident and able to communicate with a wide range of people.
