A visit to an ASHRAE event 30-plus years ago introduced David Heckler to VRF technology, and the distributor was won over. VRF systems now make up about half of his company’s business.

Customers looking for increased value out of their HVAC systems will find high-end features like connectivity, greater efficiency, and more intuitive controls attractive.

HVAC industry representatives are pushing back on a bid by more than two dozen public interest groups for an eventual ban on new fossil-fuel-burning heating appliances.

Manufacturers will have five years, from the date the rule is published in the Federal Register, to ensure that new gas furnaces comply with the new minimum.

The latest rule will require every mobile home gas furnace — and every new residential, non-weatherized gas furnace — to have a minimum annual fuel utilization efficiency (or AFUE) of 95% starting in late 2028.

This is another episode where we mainly announce topics related to the podcast itself.

In this episode Eberhard Wolff speaks with Jürgen Höller, the co-found of the Spring framework. Spring is a tremendously successful Java framework so they discuss the design of large frameworks and the issues that arise in the evolution.

Luis Rodríguez, CTO of Xygeni.io, joins host Robert Blumen for a discussion of the recently thwarted attempt to insert a backdoor in the SSH (Secure Shell) daemon. OpenSSH is a popular implementation of the protocol used in major Linux distributions for authentication over a network. Luis describes how a backdoor in a supporting library was recently discovered and removed before the package was published to stable releases of the Linux distros. The conversation explores the mechanism of the attack through modifying a function table in the runtime; how the attack was inserted during the build; how the attack was carefully staged in a series of modifications to the lz compression library; the nature of “Jia Tan,” the entity who committed the changes to the open source project; social engineering that the entity used to gain the trust of the open source community; what forensics indicates about the location of the entity; hypotheses about whether criminal or state actors backed the entity; how the attack was detected; implications for other open source projects; why traditional methods for detecting exploits would not have helped find this; and lessons learned by the community.

If you publish an RSS feed, you should do a solid for the developers of RSS readers by including a guid in each item. The guid's job is to be a unique identifier that helps software downloading your feed decide whether it has seen that item before. Here's the guid for an item on the arts and technology blog Laughing Squid:

<guid isPermaLink="false">https://laughingsquid.com/?p=914660</guid>

No other item on Laughing Squid will ever have this guid value. It's a URL that loads a blog post with the title Playful Elephant Pretends to Eat Woman's Hat. If you load the guid's URL https://laughingsquid.com/?p=914660, it redirects to the permanent link of the post. Because the guid is not the permanent link, there's an isPermaLink attribute with a value of false.

Most guid values in RSS feeds are the permanent link of the item, as in this example from the world news site Semafor:

<guid>https://www.semafor.com/article/07/07/2023/us-jobs-data-what-experts-make-of-the-new-numbers</guid>

A drawback of using the permalink is that if any part of the URL changes -- such as the title text or the domain name -- the guid changes and RSS readers will think this is a new item to show the feed's subscribers, when it's actually a repeat.

A guid doesn't have to be a URL. It can be any string that the feed publisher has chosen to be unique. Here's the guid from the RSS Advisory Board's feed for this blog post:

<guid isPermaLink="false">tag:rssboard.org,2006:weblog.217</guid>

Our guid follows the TAG URI scheme, a simple way to assure uniqueness by putting these five components together in this order:

1. The text "tag"
2. A domain owned by the feed provider
3. A year the provider owned that domain
4. A short name for the feed different from any other feed on the site
5. The internal ID number of the post

There's different punctuation between each component. The year 2006 was when the board began using the domain rssboard.org. No one else used that domain that year, so any feed reader that stores "tag:rssboard.org,2006:weblog.217" as this item's guid should never encounter that value in any other item on any other feed.

To see how RSS 2.0 feeds are using guid, several thousand feeds were downloaded this evening from an RSS aggregator that publicly shares the OPML subscription lists of its users.

The term guid means "globally unique identifier," but RSS 2.0 does not require global uniqueness in guids. Because the TAG URI scheme does a good job of serving that purpose, Blogger, Flickr, MetaFilter, SoundCloud and The Register are among the sites using it in their feeds.
