Meet the first web server in the world! ... and the first release for this year ;)

I was browsing wikipedia to see some physical thinks about CERN and accidently found this image:



According to wikipedia this is the first web server, that sir Tim Berners Lee used in CERN when he invented the HTML to allow physisists to exchange scientific information.

Isn't this exciting?

From that server it started to end up here:


And this is not the end.
This is just the beginning.

How far can we go?
As I said, I think this is just the beginning.
We have the passion to achieve more.
We have the strength to achieve more.
That is why we do achieve more.

Push yourslef to the max,
don't worry about the controls, leave them to us :).

Introduction to programming with C#

As Vesko Kolev stated in his blog - a new bulgarian book about C# programming is in progress.
I decided to take part because it seems very interesting. I haven't much experience in publishing so it will be very beneficial for me to work on this.
Actually I was author in a software magazine few years ago (as far as I remember I was about 17 years old so it must have been about 6 years ago). It should help me as I took the first chapter - introduction to programming where I will show the readers how to install Visual Studio 2010, how to start their first project and how to write their first program, some diagrams of the .NET framework 4.0 will also be included in this chapter.

We decided not to include any advanced features in this book, just core programming language, no extensions, no lambda expressions, no var, no automatic properties, no nothing.
This is because this book targets potential software developers and not software developers. It should show the developer how to code, how to think etc. We decided that if a man / lady without any software experience may think that auto property won't take memory after it doesn't involve variables (at least visualy :).
That is why we do only core things.

Wish us luck. We would really love to expand bulgarian software development community with few more people :). After all if even one guy / gal of all the people that will potentiall read the book becomes an expert - our mission would be completed (we are dreaming for more impact ofcourse :).

As Svetlin Nakov and Vesko Kolev said - telerik is sponsor for this book so it should be published easilly than their prеvious book - "Introduction to programming with Java" and would probably joy some more marketing efforts.

That was it about the book.
Now about my motivation to join the project no matter my personal engagements and all the work I have at telerik and at the university.
The first reason is that I am a self - taught (almost) developer.
I never had degree that will help me find my work, join some society of developers that will help me when I hit a difficult problem.
There wasn't even internet in my hometown. A friend of mine gave me a book on programming with Delphi (that Sams 21 days brick :).
The Delphi help also helped me and I also downloaded html files to read later when I was at school.

Then I applied for a job in the city where I was studying (Veliko Tyrnovo).
It was all my collegues that helped me improve my skills.
I don't feel as a worldwide recognised expert or something but getting to the intermediate level from nowhere is achievement to me.
So reason #1 to join this book is to give something back.

Another reason is that I would like to see how a book is written, are there different proccesses than in the software development. It has something to do with the blog posts I guess :)
So reason #2 is to steal some knowledge :)

And some kind of nostalgy would be the last reason to join :).As I said, I was an editor in a software magazine, it was very nice thing to do. The article, then the readers asking for some more information. I miss this a bit :)
Reason #3 - to feel the old days when I was an editor :)

Nice example on the Sieve of Eratosthenes algorithm

On the following address you can find a good example on how the Sieve of Eratosthenes works on the first 100 numbers.

http://en.wikipedia.org/wiki/File:Animation_Sieve_of_Eratosth-2.gif

Brief Explanation of the picture:


1. Take the first number (2), it has 2 divisors - 1 and 2 itself. So mark all the numbers that divide by 2 (the red color).
2. Take the next number (3), that is not marked by the previous step (number 3). It has 2 divisors - 1 and 3 itself, mark all the numbers that divide by 3 (green color).
3. Take the next number that is not marked by the previous steps and check if it had exactly two divisors - 1 and the number itself (the chance this number to be prime number is bigger as all the numbers that may be divisors to this number are already marked). Mark all the numbers that divide by the number choosen.
4. Repeat step 3 until the number choosen is less than or equal to the limit you want to find the prime numbers for.


Note : I would like to excuse for my poor scientific english :).
