How to Replace Your CPAP In Only 666 Days

I’m in the process of replacing a old radiator system with a centrally-ducted, air-source heat pump system with electric resistive backup heat. I’ve found that the default ecobee algorithm seems to behave surprisingly poorly for this system, and wanted to write up some of the settings that I’ve found yield better behavior. A disclaimer. I’m not...

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...

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....

One of the things we struggle with on woof.group is un-actionable reports. 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. We can choose to ignore reports from a domain, but we’d...

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...
