A product round-up of chillers on the market.

Chillers use the principles of thermodynamics to remove heat from a conditioned space. But “chiller” is a broad term that encompasses system configurations, refrigeration technologies, and methods of rejecting captured heat. Experts take a closer look.

Manufacturers are offering low-GWP refrigerant alternatives, as EPA is proposing a 700 GWP limit for most new comfort cooling chillers starting in 2025.

Like many universities across America, the University of Cincinnati faced a major infrastructure challenge: having to operate aging central utility plants with older technology.

In addition to taking up less space, smaller chillers can be more easily installed, weigh less, and pose fewer shipping, rigging, and building-construction challenges. They can also be more energy efficient, with the same or even greater cooling capacity.

By splitting the absorption process into two steps, lithium bromide solution concentrations are lower in the system, enabling lower hot water temperatures within the generator, lower hot water flow rates, and the elimination of crystallization risk within the chiller.

Chillers are being used as heat pumps, outfitted with heat-recovery systems, used in building electrification projects, and installed in arrays to cool data centers.

The proposed new approach to chilled water HVAC systems promises to provide significant capital cost savings, energy cost savings, and a path to eliminate CO₂ emissions.

GreenChill recognized nine supermarket and commercial refrigeration leaders for exceptional achievements to reduce the impacts of commercial refrigeration systems on the environment. 

With stronger global temperature fluctuations and demand for HVAC systems growing, heat exchangers are rapidly becoming essential to an ever-expanding market.

When it comes to this piece of critical infrastructure, operators need to be prepared to face new and sophisticated attacks.

Sven Johann talks with Andrew Phillips about DevOps. First, they try to define it. Then, they discuss its roots in agile operations, its relationship to lean development and continuous delivery, its goals, and how to get started. They proceed to system thinking and what “You build it, you run it” means for a system when developers have pager duty.

They continue with the diversity of DevOps requirements among companies and industries; copying ideas versus finding your own way; culture, mindset, and recommended practices; and the mandatory tool chain. They wrap up by discussing architectural styles that support DevOps and DevOps costs versus benefits.

Charles Anderson talks with James Phillips about service discovery and Consul, an open-source service discovery tool. The discussion begins by defining what service discovery is, what data is stored in a service discovery tool, and some scenarios in which it’s used. Then they dive into some details about the components of a service discovery tool and how reliability is achieved as a distributed system. Finally, James discusses Consul, the functions it provides, and how to integrate it with existing applications, even if they use configuration files instead of a service discovery tool.

Adam Tornhill, founder and CTO of CodeScene, joins host Giovanni Asproni to speak about behavioral code analysis. Behavioral code analysis is a set of practical techniques aimed at identifying patterns in how a development organization interacts with the codebase they're building. It can be used to prioritize technical debt to maximize return on investment; to identify communication and team-coordination bottlenecks in code; to drive refactorings guided by data from how the system evolves; and to detect code quality problems before they become maintenance issues. The episode starts with a broad description of the techniques, providing some examples from real projects, and ends with suggestions on how to get started with applying them. During the conversation, Adam and Giovanni touch on a set of related topics, including the applicability of the techniques to legacy, green-, and brown-field projects; ethical and privacy implications; and the importance of context when judging code quality.

Phillip Carter, Principal Product Manager at Honeycomb and open source software developer, talks with host Giovanni Asproni about observability for large language models (LLMs). The episode explores similarities and differences for observability with LLMs versus more conventional systems. Key topics include: how observability helps in testing parts of LLMs that aren't amenable to automated unit or integration testing; using observability to develop and refine the functionality provided by the LLM (observability-driven development); using observability to debug LLMs; and the importance of incremental development and delivery for LLMs and how observability facilitates both. Phillip also offers suggestions on how to get started with implementing observability for LLMs, as well as an overview of some of the technology's current limitations. This episode is sponsored by WorkOS.

An anonymous reader shares a report: Tucked inside a 32-page earnings report, oil and gas giant BP revealed it was killing 18 early-stage hydrogen projects, a move that could have a chilling effect on the nascent hydrogen industry. The decision, along with the sale of the company's U.S. on-shore wind power operations, will save BP $200 million annually and help boost its bottom line. The hydrogen industry, which has relied on oil and gas companies both financially and through lobbying efforts, is preparing for a grimmer outcome. BP has been a supporter of hydrogen. The company's venture capital arm has invested in several green hydrogen startups, including Electric Hydrogen and Advanced Ionics. Earlier this year, BP said it would develop "more than 10" hydrogen projects in the U.S., Europe, and Australia. Now, BP is scaling back those plans, saying it'll develop between five and ten projects. The company is keeping quiet about which ones will receive the green light.

The Houston Chronicle reports that celebrity gossip site PerezHilton.com has battled ISP takedown over claimed copyright infringement. The problem is, site-owner Mario Lavanderia is already disputing those claims in federal court, where a judge refused to grant an injunction. Instead, as the judicial process properly works, Lavanderia must be proven a likely infringer before his speech is silenced.

The DMCA, however, offers copyright claimants an easy route around the niceties of judicial process -- make it too much of a nuisance for an ISP to deal with an accused infringer as a client, and get his site removed. And this underscores the precarious nature of our reliance on private infrastructure. Even though the DMCA insulates ISPs from liability once they've received counter-notification, copyright claimants can still shower them with complaints, and ISPs are still free to bow to risk aversion and refuse to do business with challenging customers -- including those who challenge powerful copyright interests.

Los Angeles photo agency X17 Inc. sued Lavandeira in federal court last year, asking for $7.6 million in damages. The suit claimed Hilton used 51 photographs without permission, payment or credit, including images of a pregnant Katie Holmes, Kevin Federline pumping gas and Britney Spears.

A federal judge denied the company's motion for an injunction against the site, although the lawsuit continues, as does another filed on behalf of several other photo agencies. A lawsuit filed by Universal Studios claiming the site posted a stolen photo of Jennifer Aniston from the film "The Break-Up" is also pending.

X17 co-owner Brandy Navarre said the company has sent more than a dozen notices to the Australian Web hosting company Crucial Paradigm in the past two weeks, demanding that copies of copyrighted photos on the Perezhilton.com site be removed. "They quickly realized it wasn't worth taking on this liability just to host this one client who was a repeat infringer," Navarre said Thursday.

Tuesday, Crucial Paradigm sent a strongly worded letter to the company that represents Lavandeira, saying it had received numerous complaints of copyright violations and warning that one more complaint would result in the site being taken offline.

"Please note that with any other provider this would have been done a long time ago, and moving your site to another provider will not solve this issue," the letter read. "Continued abuse is leaving us more liable each day, which we can't afford."

PerezHilton.com appears to have found a new host in short order, but other critics with fewer resources often find themselves chilled well short of any judicial decision on the merits of their defenses.
