Wireshark is the world's foremost network protocol analyzer, and is the de facto (and often de jure) standard across many industries and educational institutions.

Wireshark development thrives thanks to the contributions of networking experts across the globe. It is the continuation of a project that started in 1998.

This month, learn what quality attributes are, how they're documented, and how they can assist you in your work as an architect.

In this second part of his series on designing software architectures, Mikko walks you through the role of the architect, from pre-planning the project prior to its inception to cleaning up the loose ends after it's shipped.

Put all that architecture design theory into practice this month, as Mikko walks you through the design of an RSS reader — from setting requirements to evaluating results

Summary: The designing software architectures series continues with a look at the 4+1 view model. The 4+1 view model lets you separate a system into four essential views: logical, process, physical, and development. Then, for good measure, it gives you one more: a use case view that describes the functional aspects of the system as a whole.

Like many other social networking sites of its ilk, Twitter too helps people remain connected. Now, it will provide a platform for a social cause – blood donation.

First, RSS and BitTorrent complement each other naturally. RSS was designed to report freshly available content, which is exactly where BitTorrent shines. RSS 2.0 enclosures were designed to automate the download process that BitTorrent optimizes.

Second, combining the two should reduce the barrier to entry for small broadcasters. While not a new idea, video blogging has always borne a bandwidth cost. Combining BitTorrent's cost savings with widely available RSS emitting tools should, for example, make it possible for a small group of motivated people across the world to create their own news channel.

Amateur Radio is the wonderful hobby of experimentation and fun in the area of electronic communication. Every Government across the world have allocated frequencies for the amateurs to use. So if you want to transmit on these bands, embrace amateur radio! Amateurs are very very skilled in operating in tough communicating conditions. When everything else fails, Amateur Radio works just fine. Testimonies are the services of Amateurs during Sept-11 disaster, Gujarat Earthquake etc to name afew. Amateurs (HAMs) are so called not because they are not professionals at it, but because they don’t do it to make money or not have any monetory interests in it. Amateurs are usually the most knowledgable in the area of Communication and Electronics compared to even PhDs from Academic Institutions when it comes to practice. If in doubt, ask a graduate engineer about Antennas and about what frequency one should transmit during a particular period of an year.

Amazon S3 supports the BitTorrent protocol so that developers can save costs when distributing content at high scale. Amazon S3 is useful for simple, reliable storage of any data. The default distribution mechanism for Amazon S3 data is via client/server download. In client/server distribution, the entire object is transferred point-to-point from Amazon S3 to every authorized user who requests that object. While client/server delivery is appropriate for a wide variety of use cases, it is not optimal for everybody. Specifically, the costs of client/server distribution increase linearly as the number of users downloading objects increases. This can make it expensive to distribute popular objects.
