If your answer is correct, Roller will take you back to the same post and will show your new comment below it, along with your name, the date and time you sent it, and the Your comment has been accepted message as shown in the next screenshot:.
In the previous exercise, we saw how to leave a comment on a weblog. This is one of the most powerful uses of blogs—someone posts about a subject you're interested in, then you leave a comment on that post, and later the owner of that post answers you back with another comment. If you leave your e-mail, both can establish a two-way communication! With Apache Roller and this book, you'll learn how to make blogs and interact with other blog owners in the ever-expanding blogosphere universe.
At the time of writing this book, a lot of companies are already using blogs to promote their products and services. There are employees from several companies who use internal blogs to communicate with other employees, and external blogs to communicate with clients, potential clients, and anyone who's interested in their professional activities, or even their hobbies. The beauty of it is that you can mix posts of your activities at work, along with posts of your hobbies and personal interests.
The possibilities with this type of "free advertising" are endless. In this exercise, we'll visit the Microsoft Community Blogs website, where you can see what Microsoft employees are writing in their blogs. Next, the Microsoft Community Blogs page will appear:. After a few seconds, you will see a list of all the blogs related to the search word s you typed:.
Scroll down the list until you find the Port Open Source Community at Microsoft blog, as shown in the following screenshot:. Next, the Port 25 home page will appear, as shown in the next screenshot it's very likely that your screen will have a different post on the front page, as this blog changes almost everyday :.
In this last exercise, you saw how Microsoft is making use of blogs so that its employees can communicate the latest news about Microsoft's posture on open source to the world. Port 25 is a weblog dedicated to the open source community at Microsoft.
Here you'll find discussions and posts on open source projects that Microsoft is collaborating with, or intends to collaborate with. However, Port 25 is just one little piece of the vast universe of employee blogs floating around.
Some blogs are hosted on Microsoft websites, and others are hosted on employees' personal sites. All in all, you'll find a lot of interesting things about Microsoft and also about its employees' hobbies, personal experiences, and thoughts in general. This is a trend that's expanding through a lot of big companies nowadays. That's the reason why big companies such as Microsoft let their employees use blogs to communicate within the company's premises internal blogs or with the rest of the world external or personal blogs.
For example, if you are working on an open source application, you can invite other fellow programmers and web designers through your blog to collaborate with you. With Apache Roller, you can create a multiuser weblog where several users can post messages including yourself , and keep up-to-date on every aspect of the software you are developing. Then, you can release downloads so that other people can test your software and post comments on your blog about it.
And all of this without even having to move away from your PC! State University, and the JRoller Java blogging community. Those facts definitely show that Roller is one of the best open source blogging solutions for personal use, and also for small or big communities, undoubtedly.
In the next subsection, we'll see several examples of blogs and blog communities that use Apache Roller. Dave is the original creator of Roller. There's also a link to Dave Johnson's personal weblog, and several links to the downloads, the Roller Wiki, the mailing lists, and an issue tracker for developers. You can even leave comments on some of the blogs.
Imagine talking directly to the CEO of one of the most important companies in the computing industry! Who knows, maybe he could get you an exciting job! This is the U. The bloggers are federal employees who work in the Office of Citizen Services and Communications at the U. General Services Administration. Here, you'll find useful information about services provided by the government of the United States. You can also create an account and get involved in the community, sharing your IT knowledge.
This would be a perfect place to create the next killer application, don't you think? If you're into Java programming, this is a good resource to learn all you can!
When I started looking for open source software to create a blog, there were a lot of choices. At first glance, I thought it was just another name for blog applications, but when I downloaded and installed Joomla! In fact, if you want to use a CMS as a blog, it's very likely you'll need to download additional modules, because a CMS can do a lot of things besides blogging. For example, you can have an integrated forum, the news at the front page does not necessarily have a chronological order, some CMS systems have a chat and a photo gallery, and a lot of other things that were very confusing for me.
All I wanted was, a blog where I could start writing stuff about computers, programming languages, and tutorials to share with other bloggers, and who knows, maybe one day start writing the next fiction bestseller! In most cases, a blog is considered a CMS because it's used to manage content in a website. However, in my humble opinion, a blog definitely is not a CMS. With a CMS, you can do a lot more than post messages in a chronological order and receive comments. That beats one of the main purposes of a blog—to express yourself in a friendly environment, like a personal diary.
Sure, you can use a CMS as a blog, but you'll have to learn how to manage its user interface and maybe add a few extra modules or plugins.
With a weblog server like Apache Roller, you're ready to go! In later chapters, we'll talk about templates and how to modify the appearance of your blog's pages by adding video, audio, and images.
You'll see how easy it is to manage your Apache Roller server. Basically, you first need to register on the aggregator site, then configure your weblog to ping the social bookmarking site.
After that, each time you post on your blog, it will ping Technorati, Digg, DZone, and so on, and the aggregator will pick up the latest content from your blog by means of your RSS feed. The following diagram shows the full process with Technorati:. This is basically the same process for all social bookmarking sites and aggregators. So, as you can see, the URL feed or newsfeed of your blog helps you to promote your blog on the blogosphere!
The two formats used by Roller, and by almost every other weblog application and aggregator, are RSS and Atom. The following table shows these two formats—a brief description and an URL example of each one. A collection of several related feed formats used to publish information blog entries, audio, video, podcasts in a standard format. The most recent standard is RSS 2.
At the time of this writing, both formats are widely used. Atom can be considered as the future of newsfeeds, but only time will prove it. In the meantime, we can use both of them. When you subscribe to Technorati and Digg, every time you publish a post, your blog sends a ping, telling Technorati and Digg to check your most recent posts and to include them in their lists by means of an RSS or Atom feed. Then, visitors from Technorati and Digg go to your blog and, if they find it interesting, can subscribe to your RSS or Atom feeds.
The following exercise will show you the process of subscribing to a newsfeed. In this exercise, you'll visit the Apache rollerweblogger. The web browser used in this exercise is Mozilla Firefox 3. You can use other web browsers such as Internet Explorer and Safari, but then the steps described in this exercise could be slightly different. Select Subscribe to 'Recent Entries Atom ' from the pop-up list.
Next, you will see a Subscribe to this feed using Live Bookmarks message, along with a list of the most recent entries from the weblog:. Click on the Add button of this dialog box to finish the subscription process. The Atom feed will be added to your list of live bookmarks in Mozilla Firefox. To verify that the subscription worked, click on the Bookmarks menu and select Roller: free and open source java blog software to see all the entries included in the Atom feed:.
Select the Announcing Apache Roller 4. The process is the same for RSS and Atom newsfeeds. Mozilla Firefox is just one of the many available newsfeed readers. In fact, if you didn't notice in step 2 of the previous exercise, there are five options to choose from when subscribing to a newsfeed in Mozilla Firefox:.
If you click on the Live Bookmarks pop-up listbox, you can select another newsfeed reader from the list such as Bloglines, My Yahoo , or Google , or even choose a different desktop application such as Ecto, MarsEdit, or Windows Live Writer depending on which operating system you are working on. Thanks to newsfeeds and services such as Technorati, Digg, DZone, and del. In the previous exercise, you saw how anyone can subscribe to a newsfeed through the Mozilla Firefox newsfeed reader.
Now, we'll see an example of a popular newsfeed reader that can be used both in Linux and Windows environments. In this exercise, you'll create an account with Bloglines —a web-based newsfeed reader.
You can use Bloglines from Mozilla Firefox, Internet Explorer, and all the other popular web browsers. The Bloglines' main screen will appear next.
In the right pane, there will be a message stating that you haven't confirmed your account yet. Go to your e-mail account the one that you used to sign up in Bloglines and look for the "Bloglines Validation Email".
Follow the link inside that e-mail message to confirm your Bloglines account. A new web browser window will open up to tell you that your e-mail address was successfully validated.
Now you can close that window and return to the Bloglines main screen. Your screen should look like this:.
Select the Bloglines News link on the left pane. The most recent posts about Bloglines will show up on the right pane, as shown in the following screenshot:. Right-click on the Subscribe link on the right part of the screen, and select Copy Link Location on the pop-up menu, as shown:.
Close the Technorati web page window, go to the Bloglines web page that you previously opened and click on the Add link from the Feeds tab, in the left pane:. The right pane will change to show the available feeds from the URL you entered. Scroll down the right pane until you see the Subscribe button, and click on it to finish the subscription process. After a few seconds, the Technorati Front Page feed will appear on the left pane, below the Bloglines News feed, showing the number of unread items:.
Click on the Technorati Front Page link, and the most recent posts from Technorati will show up in the right pane of Bloglines:. That pretty much covers the basic procedure for using a newsfeed reader. You need to register for a free account with any of these readers before you can start adding feeds from different sources.
However, once you start using them, you'll see all the power that newsfeeds can bring to bloggers. The best of all is that, when you finish reading this book, your blog will be ready to take advantage of newsfeeds and feed readers, so that people from all over the world can see your posts!
Creating a subscription to the Technorati Front Page feed, and checking all recent posts to see if there's one from your blog. Registering with Technorati, Digg, and all the popular aggregators or social bookmarking sites. Now that you have an account in Bloglines, use it to start your own newsfeeds collection. You can begin with a Google search for your favorite hobbies, local news, and so on. Try subscribing to several newsfeeds from different blogs or social bookmarking sites such as Digg, DZone, or anything of your interest.
Explore all of the settings available in Bloglines that is, open posts in the same window or in a new one, display entire posts or just a summary, and so on until you feel comfortable using it. Try to create accounts on the other two web-based feed readers Google Reader and My Yahoo , and compare features between them and Bloglines. In this chapter, we learned about weblogs, and how they can be used to create a world presence through the blogosphere.
The chapter also covered the basics about newsfeeds and the important role they play for blogs. You worked with the Mozilla Firefox integrated newsfeed reader and Bloglines—a popular web-based feed reader.
We also saw several live websites that use Apache Roller as their blog server. What you can do with a weblog—express your feelings to the world, get in touch with other people, promote your business or professional activities, share experiences with other users, and who is using Apache Roller. A brief comparison between a blog and a CMS. What are newsfeeds and how are they used in conjunction with blogs to spread information on the blogosphere.
This is just an introduction to the world of blogs and the blogosphere. You can get the release files and the official documentation via the Apache mirrors at this page:.
And you can read about the new features on the What's New in Roller 4. Support for a release is provided by project volunteers on the project mailing lists.
