A research team from York University have been working on developing more practical and streamlined devices to assist humans with everyday movements, such as standing and sitting. The objective was to determine if energy could be regenerated in prosthetic devices during these movements, similar to the way in which hybrid electric vehicles recover waste heat from braking and convert it into useable energy.

ABC argues the rule could end up hurting legitimate contractors in the building trades, who are already strapped for workers.

In recent years, the cost of HVAC equipment has increased significantly, and regulatory changes, such as the phase-down of R-410A, will make the new A2L units even more expensive.

Sales of VRF systems continue to rise unabated, leading many to predict their shipments will increase by double digits annually for the foreseeable future.

Most of the rest of the world has relied on ductless mini-split systems for their heating and cooling needs for decades, but that has not been the case in the U.S. That may be changing with the advent of ducted mini-split systems.

Often considered to be an affordable, reliable heating and/or cooling system for a variety of commercial buildings, the standard rooftop unit used to come with a basic thermostat that is limited to turning the system on or off. The advent of new controls has changed all of that by allowing rooftops to monitor operation, analyze conditions, and make real-time decisions that can optimize performance.

There’s no doubt the connectivity of mobile devices has made our personal lives more convenient, but now they’re also helping make technicians more efficient, thanks to tool manufacturers developing wireless-enabled devices and test and measurement apps for download.

Contractors are seeking tools that are equipped to handle A2L refrigerants, offer Bluetooth and wireless compatibility, operate efficiently, save the user time, and are safe to utilize.

Contractors who are embracing the technological advancements say ignoring a new neighborhood of home automation products could be a big mistake.

Products are emerging that help simplify homeownership.

In this Episode we talk to Ted Neward. Since Ted is active in the .NET and Java universes, we started out by discussing some of the differences between the two platforms. The main discussion, however, focussed on new features in the C# 3.0 language. These include LINQ (language-integrated query). A very interesting discussion about extension methods, lamda expression, typing (dynamic, duck, compiler) and other language "tricks" follows. We also visited the topic of language development on the .NET and Java platforms in general, also looking at topics such as concurrency and the Scala language.

SOA (Service Oriented Architecture) appears to be just another hype - after all we have been building distributed systems for quite a while now. But the real value of SOA is non-technical. In this episode Eberhard and Markus discuss the advantages and disadvantages, what SOA actually is and how it compares to other approaches that have been tried out before.

In this, as well as in the next episode Eberhard and Markus continue their discussion about SOA (the episode got too long, so we had to split it into two ... SOA 2a and SOA 2b). In this episode, we talk about the various perspectives on SOA (CBD, EAI, BPM), about fundamental requirements towards an SOA, and we discuss the role of models in defining sustainable architectures. We also discuss how a programming model based on the described approach typically looks like. We then discuss a number of issues any large-scale SOA faces (and for which the SOA paradigm does not really provide an out-of-the-box solution: In this episode we discuss data type ownership and (weak) typing of data types.

This is the second snippet of the SOA 2 double-episode. Eberhard and Markus continue the discussion with the issue of service reuse and a couple of development process issues. We also look at the duality between infrastructure development and application development in the context of an SOA. We then discuss the great spaghetti misunderstanding :-). We conclude this episode with a look at how to integrate BPM into the conceptual SOA framework we've built up to now, and we'll also briefly skim over a number of technologies related to SOA. Note that this episode, as well as the last one, is based on a set of slides; these can be downloaded from here. This episode covers slides 39 through 74.

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
