Only a small amount of people don't know what eBooks are. Almost everyone has used one before.

I gathered some websites with free eBooks for download hopping they can come in handy.

FreeTechBooks.com

This site lists free online computer science, engineering and programming books, textbooks and lecture notes, all of which are legally and freely available over the Internet.

Classical Authors Library

Here you can find the Classical Authors library containing over 1000 books. All the books you wished to read but you can't find or just don't want to buy, here they are. All the classic books you heard about all your life.

Tech Books For Free Download

This one has programming books. They go from Java to Python through C/C++. It also has books on database, security, and more. All you ever wanted to know about these areas, even if you are already an expert.

Free Ebook Downloads

This one has more categories than I can remember. This website can seem a bit confusing with all the Google adverts, but the info is there and it is worth it.

There are much more websites for free books out there, but these four will keep you entertained for a few weeks.

When email has just been introduced, the only kinds of messages sent were in the form of text or purely numbers and letters with no pictures yet. Until later people started sending out movies, graphics, figures, illustrations, sounds and almost all sorts of files. These non-text messages are usually grouped together and known as binary data. MIME is the way to standardize the moving of binary and non-binary information. Email used to have its own way of handling binary data.

One good thing about MIME is when you try to send a piece of binary data (known as “body part” in MIME lingo) you can specify what application to use in order to create the data. If you would send someone an Excel spreadsheet from your laptop and your MIME mailer properly labels it, it can be read on the personal computer provided that it has the software installed. The software will display an Excel icon and whoever received your file will just click the icon to launch the Excel and open the spreadsheet.

MIME became more popular when programmers integrated it into web protocols. Whenever you click a link on-line you will get a MIME message transferred to your computer. Depending on the situation, sometimes it contains HTML tags and if they have pictures it has GIF or JPEG files. The entry will depend on the browser that feeds this binary data to applications. The operation should be safe especially the simple ones like displaying pictures or play movies. Applications today are a lot smarter compare to yesteryears and the macros now that are part of the document are a lot more dangerous and more sophisticated.

Using Microsoft Word tries opening a document and for all you know you could be executing a Visual Basic script to send your Quicken files out through the email. In much the same way a virus can also be included in the file and once you open it - it goes directly to your hard drive and damages it. Thank that solutions to these problems are now readily available.

Email readers will launch applications to read MIME body parts in the same way that web browsers do; and since Netscape and Microsoft have both built Java script into their browsers that enabled web browsing Java-enabled to make the programming language easier and be understood in its general purpose.

The intention is to allow the browsers run Java programs from sources not known to the user and get into a secure environment. Theoretically, the parts of the Java that can write and read files from the hard disk to make an outgoing connection will be disabled. But Java programmers are just human and cannot perfect their work and the codes. There will always be security issues like a Java file taken from the internet by viewing a site with Java applet can be used to spy on what you are doing on-line.

In the latter part of the 90s, to counter this harmful Java applets, Finjan Software introduced a security program called SurfinBoard, the purpose of this Israeli startup is to monitor any Java applet that enter your computer's system.

Make sure you know how your browser works and what it does to keep your system safe. Check on the Settings or this is also refer as Preferences or Options in your menu bar to see what helper applications can be used. When you use a helper program be sure that you know where this coming from. Avoid scenario in which you will be asked to download a file or program by following a link but this version is not from the site known to you and it does not serve its purpose.

If you do not want to install a Java security program then turn off the browser's Java capability and remember to always back-up your files. You may want to send your own files to your own email and keep it safe on the web rather on your hard disk. MIME messages on the web help extend the safeties of your file. But remember, there is no absolute security but somehow it lessens the burden of inconveniences.

We will be writing a simple program called the Hello World program First open up notepad then type the folowing into your notepad. class HelloWorld { public static void main (String[] args) { System.out.println("Hello World"); } } Then save it as HelloWorld.java

Compiling

First open a DOS window and go to the directory where the helloworld file you saved is. type in javac HelloWorld and hit enter if this fails and says something like javac isn't a recognised command then you have to go to My Computer and click View system information then click the Advanced tab then click environmental Variables then click new what you put in variable name is PATH then for Variable Value you put in the directory where the java file is.

Running

Open a DOS window and go to the directory where the .class version of your HelloWorld file is then type java HelloWorld and the out put you should get is Hello World!.

1. Go to Systemrequirementslab.com.
2. Press "CAN YOU RUN IT?".
3. Select a product from the drop-down list. I have chosen Gothic 3. Now press "CAN YOU RUN IT?".
4. You will be asked to install ActiveX/Java. Install it.
5. Now wait. “System Requirements Lab” is analyzing your PC.
6. Now you will see the results. If minimum requirements have passed - you can play the game, if recommended requirements have passed - your PC is perfect for the game you have chosen. If requirements have failed, don't worry, “System Requirements Lab” will tell what's wrong and what can you do about it.

To start the real time counter of DAS you click on the traffic monitor-link after you have logged in. Every time when you have a visitor on your site you will hear a small beep sound (can be switched off). You will also see the next details about these visitors:

• The IP-address
• The referrer (that’s the page were the visitor came from came)
• The host (details about the internet provider of the visitor)

When you move your mouse to a particular phrase within this visitors report, then you will see supplementary details about this visitor. You will see information about the browser, the screen resolution, the operating system, the time zone and if a visitor is a unique visitor or not (a not unique visitor was already on your site).

The real time counter of DAS works as it should and is easy to operate. Big advantage of DAS is that its use is free of charge. Next to this version of the traffic monitor, you can also download it completely at reinvigorate.net and install it on your own server. This can be difficult because in that case you will have to install Java on the server.

Success!
