How to Hire, Real World Distributed Systems, 3D-Printed Ceramics, and Approximate Spreadsheets

  1. How to Hire (Henry Ward) — this isn’t holy writ for everyone, but the clear way in which he lays out how he thinks about hiring should be a model to all managers, even those who disagree with his specific recommendations.
  2. From the Ground Up: Reasoning About Distributed Systems in the Real World (Tyler Treat) — When we try to provide semantics like guaranteed, exactly-once, and ordered message delivery, we usually end up with something that’s over-engineered, difficult to deploy and operate, fragile, and slow. What is the upside to all of this? Something that makes your life easier as a developer when things go perfectly well, but the reality is things don’t go perfectly well most of the time. Instead, you end up getting paged at 1 a.m. trying to figure out why RabbitMQ told your monitoring everything is awesome while proceeding to take a dump in your front yard. An approachable argument for shifting some consistency checks to application layer so the infrastructure can be simpler.
  3. 3D Printed Ceramics to 1700°C (Ars Technica) — The key step used in the new work is to replace the standard polymers used to create ceramics with a chemical that polymerizes when exposed to UV light. (These can have a variety of chemistries; the authors list thiol, vinyl, acrylate, methacrylate, and epoxy groups.) This means they’re able to be polymerized using a fairly standard 3D printer setup. In fact, the paper lists the model number of the version the authors bought from a different company.
