Cleaning evaporator coils in a walk-in cooler can be challenging, but it needs to be done in order to keep the system operating efficiently.  

The moment for geothermal seemed to have arrived several times since the 1970s. A number of factors are forecasting wider use of this type of heating and cooling solution.

Since they don’t have to stay in one place, portable cooling units have been known to show up in some pretty unique places. Here’s a closer look at how portable units are serving in some outside-the-box applications.

The benefits of portables, including speedy implementation, reduced downtime, and cost-effectiveness, are continuing to gain recognition from end users. And, as end users experience these benefits and the resulting uptime, industry experts expect the portable market to continue to heat up.

HVAC contractors in different climates and regions all over the U.S. agree that irregular upkeep is the most problematic issue when it comes to rooftop unit failure.

The Pelican™ case housing provides a watertight, crushproof, dust-proof enclosure with heavy-duty deflector ribs for extra protection from shocks and impacts.

Investing in the right tools will save your employees’ time and avoid delaying repairs in the rush of summer.

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.

If you export your WordPress blog, it is delivered to you as an RSS feed that holds all of the blog's entries, pages and comments. WordPress makes use of five namespaces and calls the format WordPress eXtended RSS (WXR). I'm working on a Java application that converts a WXR file into a set of static HTML pages.

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:

Want to know how sleep "resets" your brain? How memories are formed and retained?  Then watch The Benefits of a Good Night's Sleep, embedded below, and learn how sleep balances and regulates the body's vital systems which, in turn, affects declarative and procedural memory.

This short TED-Ed lesson by Shai Marcu is an important topic as school starts and students will soon be staying up late or all night in order to cram for tests and other educational requirements. Marcu goes into detail describing the neurological importance of 8 hours of sleep, but the application is interesting as going to sleep three hours after memorizing math formulas (declarative memory) and one hour after practicing music scales (procedural memory) is the most ideal.

I'm left wondering what I might have accomplished if my sleep and learning patterns were consistent during my formative years...
