Karl Wiegers, Principal Consultant with Process Impact and author of 14 books, and Candase Hokanson, Business Architect and PMI-Agile Certified Practitioner at ArgonDigital, speak with SE Radio host Gavin Henry about software requirements essentials. They explore five different parts of requirements engineering and how you can apply them to any ongoing project. Wiegers and Hokanson describe why requirements constantly change, how you can test that you're meeting them, and why the tools you have at hand are suitable to start straight away. They discuss the need for requirements in every software project and provide recommendations on how to gather, analyze, validate, and manage those requirements. Candase and Karl offer in-depth perspectives on a range of topics, including how to elicit requirements, speak with users, get to the source of the business or user goal, and create requirement sets, models, prototypes, and baselines. Finally, they look at specifications you can use, and how to validate, test, and verify them. Brought to you by IEEE Computer Society and IEEE Software magazine.

Charlie Jones, Director of Product Management at ReversingLabs and subject matter expert in supply chain security, joins host Priyanka Raghavan to discuss tackling third-party software risks. They begin by defining different types of third-party software risks and then take a deep dive into case studies where third-party components and software have had cascading effects on downstream systems. They consider some frameworks for secure software development that can be used to evaluate third-party software and components – both as a publisher or as a consumer – and end by discussing laws and regulations with final advise from Charlie on how enterprises can tackle third-party software risks.

Kent Beck, Chief Scientist at Mechanical Orchard, and inventor of Extreme Programming and Test-Driven Development, joins SE Radio host Giovanni Asproni for a conversation on software design based on his latest book "Tidy First?". The episode starts with exploring the reasons for writing the book, and introducing the concepts of tidying, cohesion, and coupling. It continues with a conversation about software design, and the impact of tidyings. Then Kent and Giovanni discuss how to balance design and code quality decisions with cost, value delivered, and other important aspects. The episode ends with some considerations on the impact of Artificial Intelligence on the software developer's job. Brought to you by IEEE Software and IEEE Computer Society.

Shannon Selbert, co-founder of Soren and developer of Oban, and Parker Selbert, creator of the Oban background job framework, chief architect at dscout, and co-founder of Soren, speak with SE Radio host Gavin Henry about robust job processing in Elixir. They explore the reliability, consistency, and observability in relation to job processing, to understand how Oban, Elixir, and PostgreSQL deliver them.

The Selberts describe why Oban was created, its history, which parts of the Elixir ecosystem they use, and why this would not be possible without PostgreSQL and Elixir. They discuss the lessons learned in the 5 years since the first release, as well as use cases, job throughput, the hardest problem to solve so far, workers, queues, CRON, distributed architectures, retry algorithms, just-once methodologies, the reliability the beam brings, consistency across nodes, how PostgreSQL is vital, telemetry data, best use cases for Oban, and the most common issues that new users face. Brought to you by IEEE Computer Society and IEEE Software magazine.

Sriram Panyam, CTO at DagKnows, discusses SaaS Control Planes with SE Radio host Brijesh Ammanath. The discussion starts off with the basics, examining what control planes are and why they're important. Sriram then discusses reasons for building a control plane and the challenges in designing one. They explore design and architectural considerations when building a SaaS control plane, as well as the key differences between a control plane and a data plane.

The software developer Niko Abeler has crawled 51,165 podcast feeds to study what RSS elements they contain. His comprehensive Podcast Feed Standard report looks at the usage of core RSS elements and namespace elements from Apple iTunes, Atom, Content, Podcast 2.0 and Simple Chapters. He writes:

In the world of podcasting, there is a great deal of freedom when it comes to the format and content of a podcast. Creators are free to choose their own audio format and feed content, giving them the flexibility to create something truly unique. However, when it comes to distributing a podcast, certain standards must be followed in order to be added to an aggregator such as Apple Podcasts. Additionally, the podcasting community has come to agree upon certain conventions that can be used to add additional features to a podcast, such as chapters, enhanced audio, and more. These conventions allow for a more immersive and engaging listening experience for the audience.

This website is dedicated to providing guidance and information on the conventions and standards used in podcasting.

There's a lot of interesting data in the RSS 2.0 report, which finds that these are the six least popular elements in an RSS feed's channel:

Over 99 percent of feeds contain the optional channel element language and the optional item elements enclosure, guid, pubDate and title. Only 0.2% of feeds contain a source element in an item.

The iTunes namespace report shows a lot of variation in support. The required element itunes:explicit is only present in 18 percent of feeds and four optional elements have less than 20 percent: itunes:new-feed-url, itunes:block, itunes:complete and itunes:title. One namespace in the report, Podcast 2.0, has been proposed by Podcastindex "to provide a solution for problems which previously have been solved by multiple competing standards" and is still under development.

The report also analyzes the audio files enclosed in the podcast feeds to determine their format, bitrate, channel and loudness. The report finds that 95.6 percent use MP3 and 4.4 percent AAC/M4A. People who like an alternative open source format will be oggravated that its sliver of the pie graph is so small it can't be seen.

If Abeler isn't tired of crunching numbers, one thing that would be useful for the RSS Advisory Board to learn is how many of the feeds contain more than one enclosure element within a single item.

After a few weeks of cold weather, cloudy skies and snow on the ground my mind begins to wander and think of where I would rather be than here. Hawaii sounds good, doesn't it? Unfortunately, my bank account usually says no to those types of dreams so I found AirPano.com which, at least, took my mind off of how cold I am and provided me a poor man's virtual vacation.

AirPano.com was actually better than I expected as it provided incredible 360 degree imagery of landmarks and cities from all over the world. Their website features "over 700 panoramas showing over 120 amazing locations of all continents including Antarctic and the North Pole" and panoramas from some 50 other locations are in the works.

Much of the AirPano imagery now includes interactive pinmarks that you can click on to learn more about the places that you are visiting (as you can see on the Venice, Italy panorama below). I think AirPano is a great way to learn about other parts of the world, not only from the amazing images, but also from the history and facts about each site that they provide. Last, but not least, it is a great way to get your mind off of the cold winter weather...
