This e-book includes a summary of sustainable HVAC developments, in particular of heat pumps and refrigerant changes to address climate change.

As heat pump technology advances and begins its march into colder climates, industry experts are expecting rooftop units to continue to gain popularity in both new construction and retrofits.

As people around the world prepare to celebrate Earth Day, it’s a good time to incorporate renewable energy solutions, like Thermal Energy Networks (TENs), into the ongoing conversation.

Variable-speed heat pumps, which dominate the heat pump market in many countries, are getting more attention in the U.S. The NEWS asked several manufacturers about the benefits of the technology.

This new private-public partnership wants to quadruple heat pump installation in California over the next 6 years.

One innovation leading the way in home comfort and efficiency is an air-to-water monobloc heat pump, which offers a blend of efficiency, sustainability, and cutting-edge technology.

Two major HVAC industry organizations have weighed in on a DOE proposal that would phase out noncondensing gas furnaces for consumer use beginning in about six years.

Throughout March, voters will help the staff at Peterman Brothers select four charity partner organizations for 2023.

The decision is a win for the California Restaurant Association, which challenged the ban that took effect in 2020. The city has not decided whether to appeal.

A homeowner in Pickering, Ontario works with an experienced HVAC pro to improve comfort, efficiency, and energy savings with a high-efficiency hydronic forced-air furnace upgrade.

In this Episode we talk about the Scala language with its creator Martin Odersky. Scala is a language that fuses object oriented and functional programming. Martin started out by providing a two-minute overview over the language, and then talked a little bit about its history. We then discussed the basics of functional programming. The main part of the episode features a discussion of some of the important features of the Scala language:

• Case Classes and Pattern Matching
• Multiple Inheritance and Compound Types, Traits, Mixins
• Closures
• Functions as types, "Function pointers", Anonymous functions
• Higher Order Functions
• Currying
• (Sequence) Comprehensions
• Generics
• Type Bounds (Upper, Lower)
• Static/Dynamic Typing, Type Inference
• Operators
• Implicits

In this episode we talk to Christof Ebert about requirements engineering. As the name "engineering" suggests, we need to be systematic when working and managing requirements. Christof will structure RE into several activities, namely elicitation (identifying the relevant requirements), specification (clearly describing requirements), analysis (synthesizing a solution), verification and validation (achieving good requirements quality), comittment (allocating requirements to a project, product release or iteration), and management (keeping track of the implementation status of requirements). In this episode we discuss these activities and highlight lots of practical guidance.

In this episode, Allan shares his insights about how learning is a necessary part of software development. He covers the personal as well as the team and the organizational level and offers practical advice.

In this episode we talk with Doug Simon from Sun Microsystems Laboratories about the Maxine Research VM, a so-called meta-circular virtual machine. Maxine is a JVM that is written itself in Java, but aims at taking JVM development to the next level while using highly integrated Java IDEs as development environments and running and debugging the VM itself directly from the Inspector, an IDE-like tool specialized for the Maxine VM. During the episode we talk about the basic ideas behind Maxine, what exactly "meta-circular" means and what makes it interesting and promising to build a Java VM in Java. We talk about the relationship to Sun's current production JVM (HotSpot) and about ideas and directions for the future of Maxine.

This episode is a conversation with "Uncle Bob" Bob Martin about agile software development and software craftsmanship specifically. We talk about the history of the term, the reasons for coming up with it some of the practices and the relationship to other agile approaches. We conclude our discussion with an outlook on some of todays new and hyped programming languages.

Jay Kreps talks about the open source data store Project Voldemort. Voldemort is a distributed key-value store used by LinkedIn and other high-traffic web sites to overcome the inherent scalability limitations of a relational database. The conversation delves into the workings of a Voldemort cluster, the type of consistency guarantees that can be made in a distributed database, and the tradeoff between client and the server.

This episode is an update on the developments around the Scala language.

We talk with Martin Laforest about topics ranging from how quantum computing works, which different models of quantum computing are explored, current and future uses of the approach as well as the current state of the art.

In this episode, Markus talk with Martin Fowler and Rebecca Parsons about domain-specific languages.
