It seems that the media has become crazy in its pursuit of the coverage of bird flu. I was tracking down coverage of the flu in Internet and was really astonished to find out that all the major newspapers, magazines, television channels, web sites are in a fierce competition to give the latest information about the spread of flu in Africa, Europe and Asia. There is nothing wrong in it as it is their job. However, what scares me is the fact that they are giving too much emphasis on the scary side of the crisis. This can cause serious emotional fear and unrest to many people around the world- specially to those people who are not so much well informed about the nature of bird flu.

Of course, bird flue is a serious crisis for world economy as it is going to seriously disrupt everyday life in many countries. It will also affect the tourism and traveling industries very negatively in the short term as many people will get scared to travel to the countries affected by this crisis. The one possible negative effect that no one is seriously contemplating is the fear it is causing about eating poultry products. As a result, it will seriously hamper the industry and millions of people who earn their livelihood from this industry. Poultry products form an important part of our daily meals and if many of us want to avoid it then we have to look for alternatives like beef, mutton or even fish. Then, serious pressure will occur to meat and fish producers and suppliers. It is much easier to produce and supply eggs and meat of chickens than beef or mutton. That is why trying to substitute chicken with beef or mutton will not be possible for everyone. On the other hand, from health perspectives chicken is much better than beef or mutton. The second problem is rather psychological. We now live in a world with a lot of insecurities from different matters. Violence and terrorism, drug addiction and road accidents, AIDS- these things are perhaps more than enough to keep us scared all the time. Now we have some things extra to wander about.

The international media should come forward to help the people in overcoming their fear. Bird flu is indeed a very serious matter and it is affecting and destroying thousands of chickens on the world. Now it is no longer limited to the birds only but gradually infecting human beings in various parts of the world. However, the media should give more coverage to the ways of saving ourselves in case of a disaster takes place in our respective cities. There should be more information about the vaccine of bird flu so that we can be prepared very well. If we know about it and if we are were prepared then we will get less afraid. On the other hand, too much of watching and reading so much about the dangerous aspects of flu will only make us more afraid.

You make a living writing enterprise java applications, and you would like to work on your own projects for fun or profit, you would like to create your own web site or you would like to have a place to host your open source project. You look around for hosting providers, and all you see is PHP and PERL support, with very few hosting companies supporting Java, what to do?

Although the number of hosting companies supporting Java is increasing, support varies from nearly non-existent to companies that are deeply committed to their Java support.

There are three types of hosting plans available:

  • Shared hosting
  • Virtual Private Server hosting
  • Dedicated Server hosting

With a shared hosting plans, several web sites are hosted on the same server, sharing the server’s resources and using the same IP address. Virtual Private Server (VPS) plans consist of a server that is split into multiple virtual servers, each virtual server has it’s own IP address, some companies call these types of plans Virtual Dedicated Servers. Dedicated servers are the most expensive type of plan, each dedicated server customer gets their own physical server, nice to have, but prohibitively expensive for personal web sites and small operations.

At Ensode.net, we recommend that you find a hosting company that provides Virtual Private Server (VPS) support (some hosting companies call it Virtual Dedicated Server), since they provide a nice balance between price and control. A VPS server is like having your own server, usually with root access, which gives you the freedom to install any application you might need, including version control systems like Subversion or CVS, WebDAV, or anything else you might need. With a VPS plan you will most likely get your own IP address, and your server will be not only your web server, but also your mail and database server.

VPS hosting plans tend to be somewhat more expensive than shared hosting plans, but it is our belief that they are worth the extra cost since they provide much more control and flexibility. If you are a Java developer, chances are you are used to “getting your hands dirty”, and working on a server using good old Unix commands. Shared hosting plans tend to have “user friendly” (dumbed down?) interfaces, which might simplify administration, but can also severely limit what you are able to do, for example, let’s say a shared hosting company gives you 300 megabytes of disk space to host your web site, and an additional 300 megabytes for your email, if your web site takes 5 megabytes of space, but your email server is getting full, there is no way to allocate more space to store emails and reduce the allocation of web space. In addition to leaving you unable to reallocate resources as needed, you can also forget about installing any applications on your server. Another disadvantage of shared hosting plans is that an IP address is shared among several customers, which could have potential problems. For example, if one of the customers uses their mail server for bulk emailing, the IP address of that mail server may be banned from several systems, in a shared hosting plan environment, this would affect all the customers using the same server.

With few exceptions, shared hosting plans that support Java do so through a shared JVM, which means that you have no way of starting or stopping the JVM, and the same JVM is used to run the Java applications of all the hosting company’s clients on the server. With a VPS plan, since you have access to your own (virtual) server, it is a given that you get full control over the JVM.

You can use your favorite search engine to find companies that offer VPS plans. Good luck and may your site become immensely popular.
