Nick Tune and Jean-Georges Perrin join host Giovanni Asproni to talk about their proposed approach to modernizing legacy systems. The episode starts with some high-level perspective to set context for the approach described in their book, Architecture Modernization (Manning, 2024). From there, the discussion turns to important details, including criteria for deciding which aspects to revisit; some of the activities, processes, and tools; and the importance of data engineering in modernization efforts. Nick and Jean-Georges describe how to successfully implement an architecture-modernization effort, and how to fit that work with the teams' other priorities. The episode finishes with some warnings about the typical risks associated with modernizing a legacy system, and suggestions on how to mitigate them.

Jonathan Horvath of Z-bit discusses physical access control systems (PACS) with host Jeremy Jung. They start with an overview of PACS components and discuss the proprietary nature of the industry, the slow pace of migration to open standards, and why Windows is commonly used. Jonathan describes the security implications of moving from isolated networks to the cloud, as well as credential vulnerabilities, encryption using symmetric keys versus asymmetric keys, and the risks related to cloning credentials. They also consider several standards, including moving from Wiegand to the Open Supervised Device Protocol (OSDP), as well as the Public Key Open Credential (PKOC) standard, and the open source OSDP implementation that Jonathan authored.

The RSS Advisory Board has published the RSS 2.0 Specification for 20 years, releasing 10 revisions over that time. The current version of the specification can always be found at this URL:

https://www.rssboard.org/rss-specification

The revisions have mostly been minor, aside from one clarification that namespaces can be used to extend RSS by adding elements and attributes, not just elements.

The best way to learn how to implement RSS as a software developer is to read the RSS Best Practices Profile created by the board. It includes all the rules of the specification along with our recommendations for how to handle issues that have arisen among implementers.

For example, the enclosure section describes how to deal with the biggest ambiguity in RSS: Can an item contain more than one enclosure?

The RSS specification is available under a Creative Commons Attribution/Share Alike license, so it can be republished on websites and software related to RSS and syndication under those terms.

An effort is underway to examine how feed publishers and feed consumers are handling the lack of clarity in the RSS 2.0 specification about whether an item can contain more than one enclosure. The RSS Best Practices Profile recommends that a feed item should contain no more than one enclosure "for best support in the widest number of aggregators," advice worth testing against current usage.

The artisanal small-batch blogging service Micro.blog is a platform for sharing short posts like Twitter, but in a way designed to be less viral, more low key and less prone to provocation, attention seeking and clout chasing. There are no follower counts, public likes or trending topics. Founder Manton Reese explained why in his book Indie Microblogging:

Big social networks like Instagram are designed to amplify accounts that gain traction, whether they are fake or not.

Micro.blog limits search and avoids public likes and reposts so that the snowball starts small and stays small. Instead of going viral and becoming a major problem, fake accounts can be spotted early and shut down if necessary.

Since being funded by a Kickstarter campaign in 2017 that hit its goal in one day, Micro.blog has attracted a dedicated following. One of the options available to premium subscribers is to host a podcast. An audio button appears below the post editing window to choose a media file.

Micro.blog sites have a primary RSS feed and a separate podcast feed. The latter contains enclosure elements. Because the Micro.blog editing window does not allow more than one podcast to be added to a post, the RSS item for a post contains only one enclosure:
