This enables users to control their hydronic radiant panel, baseboard, or radiator to heat to the exact temperature and from wherever they may be.

From the start, the home’s development team at Legacy Custom Built Homes had big goals for the 6,600-square-foot, three-level home in terms of both efficiency and design aesthetic.

The project team and property management realized they needed to maximize open space for use by hotel guests. They chose LG’s Multi V™ 5 and Multi V™ S VRF systems, noted for energy efficiency and flexibility in design and installation options.

Contractors have numerous options for offering homeowners solutions in energy management systems.

At this year’s AHR Expo, Fujitsu presented the ways it can make the pandemic’s new way of living more comfortable.

With cost reduction, sustainability enablement, increased comfort and performance benefits, VRF systems allow commercial buildings to gain a competitive advantage by reducing their carbon footprint and providing custom comfort to occupants.

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.

“(I’m Your) Heat Pump” is a soft, funky, R&B love song told from the perspective of a heat pump that depicts just what a heat pump can provide to its users.

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.

Residential gas furnaces must all have a minimum AFUE of 95% beginning in five years. Some in the HVAC industry say the new Department of Energy rule will ultimately hurt homeowners.

This winter, HVAC contractors might be dealing with a wetter winter than years past, coupled with more snowfall than maybe most people would like.

The biggest tip is that combustion analysis should be the first and last thing completed during any heating appliance repair.

Due to a lack of training, time constraints, and numerous other reasons, many HVAC contracting companies are not performing combustion testing, potentially compromising customers’ safety.

U.S. Senator Ted Cruz is leading the charge to assist HVAC contractors in pushing back on the final rule on gas furnace efficiency standards from the U.S. Department of Energy (DOE).

This episode is an interview with Frank Buschmann, one of the pioneers of the pattern movement in Europe. Michael and Frank discuss how it all began: the first conferences on patterns and the first publications by the Gang-of-Four and the POSA 1 team. Frank then elaborates on the new volumes in the Pattern-Oriented Software Architecture book series - POSA 4 and POSA 5 - and gives some examples from the books. The episode concludes with a general discussion on software design and architecture, and best practices on software development.

In this Episode we talked about the new POSA 4 book which has recently been published. We talk to two of the authors, Kevlin Henney and Frank Buschmann (the third author, Doug Schmidt was not available - and he had also been on the podcast a couple of times :-)). The book contains a pattern language for distributed systems. It contains 114 patterns that had been published before by many different other authors. The patterns have been rewritten to form a consistent language. We basically talked through the different sections of the book, which gives a really good overview over the challenges and the solutions of building distributed systems. These sections include From Mud to Structure, Distribution Infrastructure, Event Demultiplexing and Dispatching, Interface Partitioning, Component Patitioning, Application Contrl, Concurrency, Synchronization, Object Interaction, Adaptazion and Extension, Modal Behaviour, Resource Management and finally, Database Access. The book references several other previous works (as listed below). Interestingly, many of these referenced works and authors have also been discussed previously on the podcast. Here are the back references:

• Domain Driven Design, Eric Evans
• Messaging Patterns, Gregor Hohpe
• POSA 2 Patterns, Doug Schmidt
• Concurrency: Part 1, Part 2, Part 3 and the interview with Goetz and Holmes
• Remoting Patterns Part 1 and Part 2
• POSA3, Resource Management

In this episode we talk about the relationship between software architecture and the business. Based on his book, Beyond Software Architecture we discuss how things such as branding, licensing, updating or different deployment scenarios influence the technical architecture of a system. We also discuss issues such as portability that add a huge amount of complexity, although from a business perspective it often does not make much sense. In the second part of the interview we discuss how the technical team and the business team can improve the way they work together. We look at some of the games (such as Buy a Feature or Give them a Hot Tub) from his new book Innovation Games, which discusses how to use collaborative play to be more creative and innovative in product creation.

In this episode we're talking to Dirk Riehle about open source business models. We started looking at the way OS projects work and defined different kinds of open source projects. In the main part of the discussion we looked at various ways of how to make money with open source: consulting, support contracts, commercial variant of an open source project, etc. We then looked at the chances and risks of each of these approaches. The next part focused on different open source licenses and how they are suitable for open source business. We concluded the episode by discussing a couple of specific questions and loose ends. After the show, Dirk informed me about the following three corrections: Black Duck Software's main product is called protexIP not IP Central, there are presently 70 licenses approved by the Open Source Initiative, and EnterpriseDB has so far acquired $37M in venture capital

In this episode Markus discusses with Chris Read basics and some advanced topics in the space of continuous integration. We cover concepts, some tools, as well as a number of best practices.

This is another episode recorded at OOP 2009, thanks to SIGS Datacom and programme chair Frances Paulisch for making this possible. Here is the abstract from the conference program: Many software systems have fragile architectures that are based on brittle assumptions or rigid architectures that reduce options and make change difficult. On the one hand, an architecture needs to be fit for the present day, suitable for immediate use, and on the other it needs to accommodate the future, absorbing reasonable uncertainty. However, an approach that is overly focused on today's needs and nothing more can create an inflexible architecture. An approach that becomes obsessed with possible future changes creates an overly complex architecture that is unfit for both today's and tomorrow's needs. Both approaches encourage an early descent into legacy for a system. The considerations presented in this talk reflect an approach that is more about thinking in the continuous present tense than just the present or the future tense. This includes principles from lean thinking, practices common in agile processes and techniques for loosely coupled design.

Gernot Starke talks about arc42: an open-source set of templates he developed to document software architecture based on his practical experience with real projects. Also Gernot and host Eberhard then discuss how documenting architecture fits into agile processes and how to find the right amount of documentation for a system. They walk through the different parts of the arc42 templates covering requirements and the context of the system and the solution structure, including building blocks, runtime, and deployment. They discuss tooling, versioning, testing documentation, and how to keep documentation up to date.

Johannes Thönes talks to Axel Rauschmayer about JavaScript and ECMAScript 6. They talk about the origin and version history. Then they dive into key JavaScript concepts and explain the features coming into the language with ECMAScript 6.

Jeff Meyerson talks with Brian Brazil about monitoring with Prometheus, an open source tool for monitoring distributed applications. Brian is the founder of Robust Perception, a company offering Prometheus engineering and consulting. The high level goal of Prometheus is to allow developers to focus on services rather than individual instances of a given service. Prometheus is based off of the Borgmon monitoring tool, widely used at Google, where Brian previously worked. Jeff and Brian discuss the tradeoffs of choosing not to replicate our monitoring data. In some situations, the monitoring system will lose data because of this decision. Other topics that are discussed are distributed consensus tools, integrations with Prometheus, and the broader topic of monitoring itself.

Eberhard talks with Florian Gilcher about the programming language Rust. Rust originates from Mozilla research. Its focus is on system programming and it is often used to replace C or C++. Topics include the concepts behind Rust; concurrent and safe programming; advanced and unique features like ownership and borrowing; the rust type system (which supports other features like traits, generics and macros). The show finishes with: the evolution of Rust based, features of libraries, and how the community works.
