Ecobee Settings for Heat Pumps with Resistive Aux Heat

Recently I’ve had users of my libraries start reporting mysterious errors due to a missing reference to SequencedCollection, a Java interface added in JDK 21: Execution error (ClassNotFoundException) at jdk.internal.loader.BuiltinClassLoader/loadClass (BuiltinClassLoader.java:641). java.util.SequencedCollection Specifically, projects using Jepsen...

For Anthem, I hope it’s the subject of a series of painful but transformative meetings. This is not an isolated event. I’ve had dozens of struggles with Anthem customer support, and...

People keep asking why Jepsen is written in Clojure, so I figure it’s worth having a referencable answer. I’ve programmed in something like twenty languages. Why choose a Weird Lisp? Jepsen is built for testing concurrent systems–mostly databases. Because it tests concurrent systems, the language itself needs good support for concurrency....

For various reasons, most of the reports we handle are for posts that are either appropriately content-warned or don’t require a content warning under our content policy–things like faces, butts, and shirtlessness.

Jepsen is a library for writing tests of concurrent systems: everything from single-node data structures to distributed databases and queues. A key part of this process is recording a history of operations performed during the test. Jepsen checkers analyze a history to find consistency anomalies and to compute performance metrics. Traditionally...
