RSS, or Really Simple Syndication, is a new way to broadcast corporate news and structured information. RSS offers a quick, easy corporate communication channel. The RSS contents are published as a feed and the feed's content keep customers, partners and journalists abreast of corporate news and information. The RSS feeds are read using a tool referred to as a news aggregator, or an RSS reader. The aggregator periodically checks to see if the RSS feed has been updated. As the feed is updated, new information will automatically appear in the RSS reader.
While RSS was at one point only considered to be a means to deliver news headlines, RSS has quickly become a powerful medium to disseminate all kinds of information. As traditional marketers are attempting to rein in content delivery, measuring e-mail open rates, click-throughs and conversions, Internet users are fighting to gain control over the content they receive. Savvy marketers and business owners are using RSS as a way to improve corporate communication and increase their external exposure and brand appeal.
What is the enclosure tag?
RSS 2.0 is quickly becoming the definitive RSS standard, all because of its support for the enclosure tag. The enclosure tag is an optional field in the RSS 2.0 specification that allows the feed publisher to include a link to a file. The file can be just about anything. Businesses have seized the opportunity, including tutorials, streaming audio lectures, PDF proposals, Power Pointâ„¢ presentations, podcasts of sales meetings, and advertising portfolios among other traditional uses for RSS.
Many businesses have yet to realize the potential hidden in the enclosure field. The implications and power of how RSS can be used is really awe-inspiring. Consider the following business uses for RSS:
1. PDF Documents - Consider broadcasting meeting agenda notes or documentation as a PDF included with a feed, allowing interested individuals to access information without having to deal with cumbersome e-mail attachments.
2. PPT Presentations - Presentations can easily be distributed in a feed enclosure. The added benefit is that presenters using Power Pointâ„¢ will not have to lug their notebook to a meeting to present - they can manage the presentation from an iPod or similar handheld that reads RSS feeds.
3. Video - Video or streaming video are both possible via the enclosure field. Have lectures or even political debates come to life with the added video component.
4. Audio - Audio content does not mean that feeds are limited to your favorite songs. Podcasting is the coined term for audio content contained in a feed and can include language instruction, talk shows or editorials.
5. Images - Imagine realtors using the enclosure field to display photos of homes to interested buyers. Now they can carry a light-weight catalog with them to show potential buyers at a moment's notice.
6. Downloads - Consider an information technology department in a large corporation conducting proprietary software updates, including executables or zip files in the enclosure field which allow users to update the software at a convenient time.
Feedreaders are playing catch- up
RSS news aggregators were initially designed to receive text-based content. As users find outside-the-box uses for RSS, developers of RSS readers are struggling to release new versions that support the enclosures businesses are eager to use.
FeedDemon, a popular RSS reader, has recently added support for every type of enclosure in their latest release. They have created a safe list that can be customized to include specific types of file types like PDFs. This will automate downloads of files that are deemed "safe". This was clearly designed with security in mind, to prevent automatic downloading of executables.
Businesses are revolutionizing RSS as a communication medium. While some traditional businesses are struggling to include monthly newsletter summaries in an RSS feed and reap the benefits of RSS, other innovative businesses are adopting incredibly creative uses for both internal and external corporate communications.

JPEG and GIF the differences
JPEG and GIF the differences
by: Maricon Williams
JPEG and GIF image formats are both compression based formats. They are the most widely used and supported image formats for web. They take an uncompressed image such as bitmapped image and compress them to a smaller file size. A lot smaller image size is moreover the result of this conversion. It may seem that one compression may result in smaller file sizes, nevertheless that is simply not the case. Now where lays the difference?
JPEG stands for Joint Photographic Experts Group. It supports 16.7 million colors. It is ideal for photographic images and high quality images. JPEG is a lossless method of compression or in common parlance, when the program that creates a GIF squashes the original image down to ensure not to lose any data. It uses an easy substitution method of compression.
GIF on the other hand, stands for Graphic Interchange Format. It supports only a maximum of 256 colors. It is the only alternative to make an image animated unless you want to use Flash. Between GIF and JPEG, only GIF allows transparency. GIF is good for images with flat expenses of color. It can be use for logos, titles, button, etc. The maximum compression of GIF depends on the amount of repetition there is in an image. A flat color can compress well to even one tenth of the original size while a complex non-competitive color will save approximately 20%.
GIF format is good at compressing images with a small number of colors with no gradations. In actual fact, most web graphics are saved in GIF by contrast when applied to JPEG, it usually results in images which are larger than their GIF counterparts and may appear corrupted.
Each image format has its own advantage. GIF may win out with the non-dithering, fewer color images while JPEG is excellent for dithered continuous tone images. An example to this is a photograph with several colors, shadows and even gradations. All these colors and shades call for the JPEG format.
JPEGs disadvantage is that it throws away parts of an image to save space. Apparently you just can’t discard any piece of information so what JPEG does is divide the image into squares. GIF is short of colors, that’s a blatant fact. Another disadvantage is that, Unisys discovered that it owned several patents to key parts of the GIF compression technology and has started demanding fees from every company which uses the GIF code. This is the reason why progress was muffled. Now that you already know the difference, you can now pick what’s good for you.

I love reading. Give me a book and I'll finish it in one sitting. Reading is the chance to be transported to a different world and so is writing. I'm more enthusiastic about writing however, since you can relay your ideas to someone else. I can only imagine that feeling when I hear a complete stranger talking about my ideas which read on an article somewhere. To relay my message to as many people is the same as touching people with music. Only mine's less harmonic. I try to make up for it with the color I bring with words. And most of the time, it’s more than enough.
