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.

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.

With this episode, Software Engineering Radio begins a series of interviews on social/nontechnical aspects of working as a software engineer as Tobias Kaatz talks to Randy Shoup, former CTO at KIXEYE, about hiring in the software industry. Prior to KIXEYE, Randy worked as director of engineering at Google for the Google App Engine and as […]

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.

The Selberts describe why Oban was created, its history, which parts of the Elixir ecosystem they use, and why this would not be possible without PostgreSQL and Elixir. They discuss the lessons learned in the 5 years since the first release, as well as use cases, job throughput, the hardest problem to solve so far, workers, queues, CRON, distributed architectures, retry algorithms, just-once methodologies, the reliability the beam brings, consistency across nodes, how PostgreSQL is vital, telemetry data, best use cases for Oban, and the most common issues that new users face.
