Today we're going to perform some AMD TRX40 motherboard VRM thermal testing using the powerful 64-core Threadripper 3990X. To apply load we're using Blender with the system running at stock and overclocked to 3.8 GHz. The typical power draw for this system is around 450 watts, but once overclocked we are hitting as much as 850 watts. Toasty!... [PCSTATS]

The RSS feeds of the RSS-Public and RSS-Board mailing lists are no longer available. Yahoo Groups used to offer feeds for each of its public lists, but Yahoo dropped support last year. A member of the service's product team said the feature was retired in July 2013.

To read the lists and subscribe to receive them in email, visit the Yahoo Groups pages for RSS-Public and RSS-Board.

We may move the lists to Google Groups, which does offer RSS feeds for each group.

One of the biggest challenges for a software developer implementing the RSS 2.0 specification is the issue of enclosures in a feed item. The specification is infamously unclear on whether an item allows one enclosure or multiple enclosures.

The RSS Advisory Board worked on the RSS Best Practices Profile for nearly two years, investigating a lot of RSS readers and feed producers to see how they handled issues like this. We ultimately made the following recommendation for enclosure:

Support for the enclosure element in RSS software varies significantly because of disagreement over whether the specification permits more than one enclosure per item. Although the author intended to permit no more than one enclosure in each item, this limit is not explicit in the specification.

Blogware, Movable Type and WordPress enable publishers to include multiple enclosures in each item of their RSS documents. This works successfully in some aggregators, including BottomFeeder, FeederReader, NewsGator and Safari.

Other software does not support multiple enclosures, including Bloglines, FeedDemon, Google Reader and Microsoft Internet Explorer 7. The first enclosure is downloaded automatically, an aspect of enclosure support relied on in podcasting, and the additional enclosures are either ignored or must be requested manually.

For best support in the widest number of aggregators, an item SHOULD NOT contain more than one enclosure.

Because the profile was completed in 2007, it would be useful to see how current software handles RSS enclosures to evaluate whether any recommendations should be reconsidered. To start this effort the current WordPress was tested, since that massively successful platform publishes 60 million RSS feeds. WordPress enables audio files to be added to a blog post using the Audio icon in the block editor:

When three audio files were added to a blog post in WordPress, the item in the RSS feed contained three enclosure elements:

Follow this blog for more updates on enclosure usage in feeds and feed readers.

As you probably guessed, we have an RSS feed.

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:
