Like spyware and malware, now we have "Ransomware".

These are a new breed of software that blackmail users to paying money.
Pay the money or else, your files are gone forever.
They spread just like spyware and get installed in the system, then starts to blackmail the users to pay money to get rid off them.

Example is a new Trojan called Ransom.a which demands a $10.99 ransom payment to stop erasing files on the infected PC's hard drive, a security firm said Thursday.

According to U.K.-based Sophos, the Ransom.a Trojan freezes the computer, then puts up a message saying it will delete files every half hour until the user sends $10.99 via Western Union to a designated account.

When the user presses Ctrl-Alt-Del, it pops up another message.

"Yeah, We don't die, We multiply! Ctrl+Alt+Del isn't quite working today, is it? I'm not the sharpest tool in the shed but Crtl+Alt+Del is everyone's S.O.S."

n mid-March, a different Trojan, called "Cryzip" and "Zippo.a," demanded $300 in return for a password that would free users' files from maliciously-made ZIP archives. Multiple security companies, however, quickly figured out the password.

Linux or Microsoft… Which one is best for you?

The operating system that you use on your computer does not need to govern your choice of hosting platform.
Both technologies are suitable for beginners, professional web developers, and everyone in between, but it is essential to choose the technology that is more suited to your style of web building. Each technology has its own distinct advantages for users.

Windows Servers

Microsoft should be your choice of platform if you plan on utilizing Active Server Pages or other Microsoft applications to design your web pages. This platform delivers reduced development time and better functionality for databases.
One of the main advantages for choosing the Microsoft platform is the ability to use ASP, ASP .NET, and Access databases to use in building your web site. ASP and ASP .NET provide a rapid, scalable, and efficient development environment to build your web site. These tools, along with MS Access will allow you to make your web site dynamic and interactive.
This platform is also a suitable alternative if you are developing static HTML based web sites, or sites that incorporate Macromedia Flash or other client-side scripting technologies.
We recommend you choose Windows 2003 as your hosting platform if you are using specific applications that require Microsoft Windows to run such as Access, ASP, ASP .NET, or Microsoft SQL Server.
Note: Microsoft FrontPage and PHP can be used on both the Linux and Windows platforms.

Linux Servers

Linux is widely considered to be the best operating system for web hosting servers. Characteristically reliable, stable and efficient, Linux has been proven in the most demanding web and mail server environments.
If you plan to incorporate work that uses PHP, Perl or MySQL, Linux is the solution you should choose. Linux is also ideal for the kind of websites that display information as a brochure, in newsletter format or as data sheets. Linux works well for 'brochure-ware' sites that offer interaction via inquiry forms, online purchasing and other e-commerce functions.
Essential programs such as Microsoft FrontPage can also be successfully used with Linux technology. Linux is an excellent operating system that is well suited to meet your web hosting needs. Additionally, there are a huge amount of free applications available on the Internet for Linux and it uses less hardware resources than Windows 2003.

For me, Windows Servers are still the choice, myself being an ASP programmer!

According to Netcraft's most recent web server survey, the amount of hostnames on the Internet has doubled within the past three years. At the end of March, Netcraft said it identified a total of 80,655,992 websites, which represents an increase of 3.1 million since the end of February. In March of 2003, Netcraft reported the existence of about 40 million web sites.

Apache, the most popular web server software on the Internet suffered a substantial slide in market share in March, the research firm said. Compared to the previous month, Apache lost six percentage points from 68.7% to 62.7% due to a large-scale migration from Apache to Microsoft software at domain registrar GoDaddy. Microsoft gained almost five percentage points and stands now at 25.2%. According to Netcraft, GoDaddy will shift a total of 4.4 million hostnames from Apache to Windows Server 2003.

.NET Architecture for Web services






J2EE Architecture for Web Services







.NET and against J2EE

• .NET has Microsoft's A-team marketing it
• .NET released their web services story before J2EE did, and thus has some mind-share
• .NET has a better story for shared context today than J2EE
• .NET has an awesome tool story with Visual Studio.NET
• .NET has a simpler programming model, enabling rank-and-file developers to be
• Productive without shooting themselves in the foot
• .NET gives you language neutrality when developing new eBusiness applications, whereas
• J2EE makes you treat other languages as separate applications
• .NET benefits from being strongly interweaved with the underlying operating system

• J2EE is being marketed by an entire industry
• J2EE is a proven platform, with a few new web services APIs. .NET is a rewrite and introduces risk as with any first-generation technology
• Only J2EE lets you deploy web services today
• Existing J2EE code will translate into a J2EE web services system without major rewrites.
• Not true for Windows DNA code ported to .NET.
  .NET web services are not interoperable with current industry standards. Their BizTalk framework has proprietary SOAP extensions and does not support ebXML.
• J2EE is a more advanced programming model, appropriate for well-trained developers who want to build more advanced object models and take advantage of performance features
• J2EE lets you take advantage of existing hardware you may have
• J2EE gives you platform neutrality, including Windows. You also get good (but not free) portability. This isolates you from heterogeneous deployment environments.
  J2EE has a better legacy integration story through the Java Connector Architecture (JCA)
• J2EE lets you use any operating system you prefer, such as Windows, UNIX, or mainframe. Developers can use the environment they are most productive in.
• J2EE lets you use Java, which is better than C# due to market-share and maturity. According to Gartner, there are 2.5 million Java developers. IDC predicts this will grow to 4 million by 2003. 78% universities teach Java, and 50% of universities require Java.
  We would not want to use any language other than C# or Java for development of new mission-critical solutions, such as a hacked object-oriented version of C, VB, or COBOL.
• We are finding most ISVs and consulting companies going with J2EE because they cannot control their customers' target platforms. We believe this application availability will result in J2EE beginning to dominate more and more as time goes on.

Common Features:

• Regardless of which platform you pick, new developers will need to be trained (Java training for J2EE, OO training for .NET)
• You can build web services today using both platforms
• Both platforms offer a low system cost, such as jBoss/Linux/Cobalt for J2EE, or Windows/Win32 hardware for .NET.
• Both platforms offer a single-vendor solution.
• The scalability of both solutions are theoretically unlimited.
