Products are emerging that help simplify homeownership.

“The acquisition of California Economizer and its Zonex Systems brings together the two oldest manufacturers of zoning dampers and zone-control systems,” said Dick Foster, the president of Zonefirst and its parent company, Trolex Corp.

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 more homeowners are ditching oil heaters and moving to heat pumps, the rest of the country can learn from the cold-climate success story.

With “heat pump” and “incentives” almost being synonymous at this point, contractors need to understand the basics to ensure customers are receiving the benefits.

Any furnace with induced draft combustion may occasionally exhibit unburned gas odor near the furnace in the off cycle.

Cold climate heat pumps were on full display on the AHR show floor and manufacturers were eager to share their progress reports in the Department of Energy’s CCHP Challenge.

This is the first of two episodes where Arno and Alex discuss eXtreme Programming in se-radio's development process track. eXtreme Programming (XP) revolutionized the way of thinking about software development methodologies and helped to make the agile movement popular. In this episode they discuss the very basics of XP, its value system, principles and the basic practices used in an XP project. The second episode will continue the introduction adding the missing practices and how to introduce XP into projects.

This is the second part of our two part discussion of the eXtreme Programming development methodology. While the first part introduced the values, principles and basic practices, this time Arno and Alex speak about the practices that set the context for an XP project and how to get started, and they discuss some FAQs they often get when introducing XP.

In this episode we talk with Gerard Meszaros about problems and challenges doing unit testing in real-world projects. Starting from a short discussion about the importance of automated unit testing we spend most of this episode to talk about every day problems doing unit testing and how those problems can be solved. Based on this book on xunit testing patterns, Gerard talks about his experiences with unit test smells as an analogy to code smells. He describes an impressive set of unit testing patterns to overcome those difficult testing situations and illustrates them with nice examples everybody doing unit testing will feel familiar with.

In this episode we're talking to Jens Coldewey about his experiences in 10 years of introducing agile techniques to project teams. We discuss real-world examples and the lessons learned and strategies derived from them.

In this episode we discuss Microsoft's OSLO platform with Doug Purdy and Don Box. We briefly discuss what OSLO is in general and then look at the various components of OSLO. We also look at how OSLO fits in with the general Microsoft strategy and how it compares to other DSL/Model-driven approaches. We then look at language modularization and composition and discuss the similarities with XML and Smalltalk. Finally, we discuss possible integrations of OSLO with other MD* approaches and technologies.

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 Scott Meyers about the upcoming C++0x standard. We talk a bit about the reasons for creating this new standard and then cover the most important new features, including upport for concurrency, implicitly-typed variables, move semantics, variadic templates, lambda functions, and uniform initialization syntax. We also looked at some new features in the standard library.

Eberhard Wolff talks with Martin Lippert of Pivotal about the Eclipse Flux project. This projects is in its early stages — and has a very interesting goal: It aims to put software development tools into the cloud. It is a lot more than just an IDE (integrated development environment) in a browser. Instead the IDE […]

Mike Barker talks with Sven Johann about the architecture of the LMAX system. LMAX is a low-latency, high-throughput trading platform. Their discussion begins with what LMAX does; the origins of LMAX; and extreme performance requirements faced by LMAX. They then delve into systems that LMAX communicates with; LMAX users; the two main components of the system (broker and exchange); Mechanical Sympathy as an architectural driver; message flow using the Disruptor library; and lock-free algorithms. Mike and Sven wrap up by discussing how a well modeled domain model can improve the performance of any system; automated (performance) tests; continuous delivery; and measuring response times.

Jeff Meyerson talks to Haoyuan Li about Alluxio, a memory-centric distributed storage system. The cost of memory and disk capacity are both decreasing every year–but only the throughput of memory is increasing exponentially. This trend is driving opportunity in the space of big data processing. Alluxio is an open source, memory-centric, distributed, and reliable storage system enabling data sharing across clusters at memory speed. Alluxio was formerly known as Tachyon. Haoyuan is the creator of Alluxio. Haoyuan was a member of the Berkeley AMPLab, which is the same research facility from which Apache Mesos and Apache Spark were born. In this episode, we discuss Alluxio, Spark, Hadoop, and the evolution of the data center software architecture.
