Accounting is an activity designed to offer you a general image of how your company is doing. Obviously, this is a thing many people need, yet Accounting is considered something very hard to grasp.
Why? Because the teachers who explain you how it works know only the theory. When you try to do yourself what you’ve been told, you’ll get stuck very soon.
“Accounting demystified” has a different approach. It does not start as teachers do, with the beginning, but with the end. It’s very important to know what IRS requires of you and why. When you’ll understand the goal, the rest falls into the right place. In order to do the final documents, you need this and that, and in order to obtain that information you need the very basic details.
“Accounting demystified” will not make you an account overnight, but it will explain clearly what you need to understand when you look to a financial statement. It’s like Accounting is a new town and “Accounting demystified” is the map, with all important places from that town, and how to get from one to another.
If you start understanding Accounting using this book, you’ll save yourself the frustration created by teachers who never owned a company, but are experts in theory.

When you start learning Chinese, how do you remember how to draw the Chinese characters? You can memorize the order of the lines, by repeating it many times. The problem is that you’ll get bored soon and you’ll abandon the study.
If you understand that the character for man simply resembles the legs of a man, you’ll remember it much faster and for a longer time. It will remain etched in your head.
A pig and a roof make a house. A child and a woman mean “good”. On each page, there is a simple and logical explanation for the character.
I didn’t read this book. I devoured every single page of it. After the last page, I had only 1 question in my mind : “Why didn’t I find this book earlier in my life?”
By the way, this is volume 1 of a 3 volumes set.

I assume you know what cookies and session variables are, but you want to know which one is best to use.
To better understand if you need cookies or sessions, here’s a comparison.
Let’s say you have a website, where the user has to log in order to access some information.
Login page is login.php, and the user wants to visit also the pages info1.php and info2.php.
Both info1.php and info2.php verifies if the user has the right to access them, that is, if the user is logged in.
Case 1 : No cookies, no sessions
The user access login.php and logs in.
Then he tries to access info1.php. Because the HTTP protocol does not remember what the user did on page login.php, it asks the user to login again. That is, it redirects him to login.php. Let’s pus aside for a moment the user’s confusion, when he sees again the login page. The problem is that the user will never be able to access the information from info1.php and info2.php.
Case 2 : Sessions
The user access login.php and logs in. Then he tries to access info1.php. The system will append automatically something like SESSION_ID=yuqe3syqxrq to any page and info1.php will figure out, from that SESSION_ID that the user is logged in. Therefore, will allow him to access the information from info1.php
The problem occurs after the user closes his browser. In that moment, the SESSION_ID is permanently lost. If the user opens again a browser, he’ll have to login again.
Case 3 : Cookies
The user access login.php and logs in. In that moment, login.php will save a cookie on the user’s computer. Then the user tries to access info1.php. The system will read the cookie, and grant the user access to info1.php.
After the user closes his browser, the cookie is still there. So, by using cookies, the user will not have to login again each time.
What if the user refuses to allow cookies to be saved on his computer? Some websites, like GMail.com, will not allow him to do anything else until he activates the cookies. Others, will try to use sessions. It depends on the person who designed that site.
So, what’s best? Cookies or sessions? It’s up to you. I would use only cookies, and tell the user that he needs cookies for accessing restricted areas of the site. If the user doesn’t trust you, to give access to cookies, chances are high that will not trust you to pay for that restricted information.
C and C++ are famous for how the concise the code can be. Apparently, this can be a great advantage – it saves you time when you write code.
This books shows you, plain and simple, that the time you save writing short code you’ll lose many times more by debugging it. Because of the concise form of the code, you might make a lot of very subtle mistakes, some extremely hard to track.
I’ve read about this problem many times. What’s different this time is that the author actually offers you a solution to avoid these kind of problems. A solution that’s so simple, yet I’ve never seen it anywhere else so far.
Exemples are presented in a very pleaseant tone, like a story. I found myeslf readiing this book for relaxation purposes. It brought me a sense of balance in my programming activity.
The concise way of writing C code is like driving without a seat belt. You feel free, right? Yes, but in case of an accident, the lack of the seat belt can cost your life.
This book will not help you satisfying the teachers who mark you by the number of lines, nor will allow you to receive the Razzy Award for the worst written code.
If C language is a machine, this book is a manual of how to drive safely. The author’s purpose is to show you how to get at the destination in one piece, without speed tickets and on time.

How to record sounds from a microphone, using Windows? You can use the program “Sound Recorder”, which comes with Windows. The problem is that you have too little options and you can’t record over 60 seconds.
Audacity is a free program, which will allow you to record sounds from your microphone. You can select your default microphone, if you have more than one.
Recording is very easy : you just press the record button. It’s equally easy to cut the part of the recording you don’t want (like the very end, where you put the microphone back on its support). You can zoom in, which will allow you to better select the segments you want to remove.
Audacity uses projects. Each recording is saved in a project. You can export your project to wav, if you want to do further processing.
Audacity has a lot of effects available. For instance, if the recording of your microphone is too low, you can amplify it, to the best level without distortion.
If you read a text, for a tutorial, you can add silence between the sentences. This way, your listeners will not hear you breathing.
After you download a file, the next step is to open it. But how do you know how to open it?
If you’re using Windows, you just double click on that file and Windows knows how to open that file, if you or someone else already installed the appropriate programs. If not, Windows will ask you to select a program, from a list of programs.
Windows knows how by default how to open certain files, like txt, bmp and so on.
If you want a simple way to know how to open a file (for instance, zip files) visit this site:
http://HowToOpenIt.com
You can search for a particular extension or you can add it after the site name.
