Next-generation ZE refrigerant blends offer customized performance that is tailored to the application, while helping support the push for decarbonization.

Any compressor that gets too hot or is overheated is subject to premature wear between its internal moving parts.

While some contractors fabricate sheet metal in-house and others outsource that work, both groups can benefit from a few best practices.

Artificial intelligence, or AI, is now able to handle many of an HVAC contractor’s administrative tasks, and also help employees perform their own tasks better.

With the scheduling map in the current system, customers can track the real-time location of vehicles.

Fleet tracking software solutions offer contractors far more than a simple interface to track their vans.

Smart tools continue to grow in the HVACR industry, spurring manufacturers to create connected, digital devices that will make work in the field less manual and more automatic.

It is hard to find a contractor who does not have a firm opinion on Nest and if the company is good for the HVAC industry.

While balanced ventilation does have energy benefits, there is a misconception about its ability to reduce humidity.

While the installation of heat pumps may seem to be slowing due to inflation and rising interest rates, coupled with a confusing rollout of federal funding, they are expected to pick up speed this year.

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.

The Anatomy of Compromise

One of my demented hobbies is watching old infosec talks and then seeing

of room for opinion, and one a lot of people have opined on, but the talk

It's impossible not to notice that we live in an age of technological
wonders, stretching back to the primitive hominids who dared to ask "Why?"
but also continually accelerating and pulling everything apart while it
does, in the exact same manner as the Universe at large. It is why all the
hackers you know are invested so heavily in Deep Learning right now, as if
someone got on a megaphone at Chaos...

Michael Hausenblas talks with host Kim Carter about topics covered in Michael’s ebook Container Networking, such as single vs. multi-host container networking, orchestration, Kubernetes, service discovery, and many more. Michael and Kim also discuss the roles that IPTables plays, how the allocation of IP addresses is handled, along with the assignment of ports. Overlay networks are covered along with topics such as the open Container Network Interface (CNI).

In this episode, David Cramer, co-founder and CTO of Sentry, joins host Jeremy Jung for a conversation about error tracking. The discussion starts with treating performance problems as errors, why you might not need logs, and how most applications share the same problems. From there they consider other topics including capturing information by hooking into runtimes and frameworks, issues with the quality of Open Telemetry data, how front-end applications are constantly changing and why that makes them hard to instrument. Finally, they discuss how Sentry's architecture has evolved, and why they switched from a permissive license to the Business Source License.

Infrastructure engineer and Kubernetes ingress-Nginx maintainer James Strong joins host Robert Blumen to discuss the Kubernetes networking layer. The discussion draws on content from Strong’s book on the topic and covers a lot of ground, including: the Kubernetes network's use of different IP ranges than the host network; overlay network with its own IP ranges compared to using expanded portions of the host network ranges; adding routes with kernel extension points; programming kernel extension points with IP tables compared to eBPF; how routes are updated as the host network gains or loses nodes, the use of the Linux network namespace to isolate each pod; routing between pods on the same host; routing between pods across the host network; the container-network interface (CNI); the CNI ecosystem; differences between CNIs; choosing a CNI when running on a public cloud service; the Kubernetes service abstraction with a cluster-wide IP address; monitoring and telemetry of the Kubernetes network; and troubleshooting the Kubernetes network.

Have you been interested in taking a MOOC (Massive Open Online Course), but don't know where to find one or how to get started?

Class Central is a free MOOC aggregator that provides links to a wide variety of courses from universities like Stanford, MIT, Harvard, etc. (offered via Coursera, Udacity, edX, NovoED, and others).

The site allows you to search for MOOCs according to the course name, instructor, subject, start date, length of course, and course provider. Class Central also offers a "MOOC Tracker" service that will send you email notifications when a MOOC that is of interest to you becomes available.

MOOCs are a great idea for your students if your school doesn't offer advanced courses for a particular subject and they are also great resources for instructors and others. Try one and I think you will find out how they can be a benefit to you. I did!
