Software Freedom Day @ Alexandria University 2011

OSUM Club at Alexandria University is pleasured to hold Software Freedom Day for this year.

The event will last for three days from 23-8-2011 to 25-8-2011 at Bibliotheca Alexandria each day we will have three session ,also there will be a contest and workshop and soft skills session.

Don't miss it!

Software Freedom Day @ Alexandria University 2011

SFD is a worldwide celebration of Free and Open Source Software (FOSS). Our goal in this celebration is to educate the worldwide public about the benefits of using high quality FOSS in education, in government, at home, and in business -- in short, everywhere!

OSUM Club at Alexandria University is preparing for SFD 2011, aiming to foster a general understanding of software freedom, and encourage adoption of free software and open standards in our community,and increase the culture of using free software in daily life.

Programming Contest

It is required from me in technical writing subject to select a topic
I have recently studied and
write 2 paragraphs about it

• The first paragraph is directed to my colleagues who has a background of the subject.
• The second paragraph is directed to my friend outside the faculty of engineering.

It is the report , may be it will be useful for you:

Programming Contest

It's complicated programming challenges with time and memory constrains.
Most probably programming contest be in teams and your team compete with
other teams to solve problems as much as you can and as faster as you can.
Problems in this contests are of special kind :

• Your program must run in determined time.

• Your Algorithm should thoroughly handle all the special cases of input.

• You should get the solution and submit it before the other teams to get a higher score.

Solving this problem requires a lot of practice in order to get used to this
problems.
You will find this practice in a lot of on-line judges, which are on-line sites.
This sites provide problems and enable you to test your solutions whenever
you want.
All this sites are for free:

• UVA
• SPOJ
  

Also there is sites which hold scheduled on-line contest to enable you to
compete with other contestant ,like:

• Code jam : which hold annual contests.
• Top Coders : which hold scheduled contests.
• ACM national,regional and international contests.

Why you need to participate in this contests because :

• That will improve your skills in problem solving.
• Improve your debugging skills.
• Get an algorithm,implement it and debug it quickly.
• Manage your work with a team.

If you don't know a lot about programming , first you should learn the basic concepts of programming to be familiar with programming languages.
In programing contestant you will find complicated problem from life ,and you are supposed to solve it using a computer program.
Programming languages represent the tool that you will use to solve the problems.
Simply your program is the ordered procedures (algorithm)that will solve the problem so before anything you should be familiar with at least one programming language.
Your program should get the answer in a short time ,that depends on how your algorithm is smart enough to get the solution from the shortest way (that is the challenge).
So you will need to study some topics that is related to algorithms and problem solving
You will find that is very hard but after a short time you will understand the concepts and you will find it very interesting.
This field is useful in the practical life ,and has a lot of applications

• Find the shortest path between two points.
• Solving geometric problems.
• Represent networks and it's operations

• To be experienced in this field just keep practice and practice.

what is behind it

How are you everybody

This is for CSDians and who are interested in programming

what's behind running our programs alot of us (not all) don't focus on what is behind running programs.

It's an introduction to :what goes into actually making a program , the steps that a compiler takes when building the program

That will improve our programming,cause understanding the phases of compilation will make it easier to deal with compilation failures

Here we will have a look to what is behind programs in C and C++

Actually it's some links which simply discuss the steps of compiling

let's start:

• compiling and linking:

briefly the difference between compiling and linking that compling process one file and poduce .object file then linking process this .object files that is declared in this

• Using multiple Source Files in a single Program :

that's about the reusabilty of the code in more than one project, that prevent from rewrite the code more than once and save in time and effort and,that implay seprating the header file from the source file ,this show how to do that

• The Preprocessor:

It is processing the code before compiling it ,it's more than including some files and defining constants, there is macros and it's tricks and more in this

• Dealing with Compiler Errors:

I think it's very important specially that errors in C and C++ are confusing so it is the types of the errors and how to deal with it

i hope that will be useful for you ,thank you for reading that
