- 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.
- 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.
- 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.

The O’Reilly Solid Podcast: Lessons from the Pop-up Factory.
Subscribe to the O’Reilly Solid Podcast for insight and analysis about the Internet of Things and the worlds of hardware, software, and manufacturing.
Coelho and Raney worked with Cranor on the Pop-up Factory, a production line that manufactured connected devices on the floor of the Solid 2015 conference. The four of us reviewed the process of spinning up the factory (which took just two months from beginning to end), and the impact of live fabrication on attendees at the conference.
- Manufacturing as a creative process, and as an input for designers
- How 3D printing reduces iteration time and enables design and production to occur simultaneously
- Manufacturing as deployment
- Why the Pop-up Factory is analogous to the Hollywood model of film production
An overview of the 3D animation process using Blender.
Creating 3D animations is like writing software. Both processes require
knowing certain industry terms. Some animation terms are:
- Setting up the scene with cameras, lights, and other effects
Let’s define each of these, and then we’ll dig into some code with Blender’s API.
Modeling is the process of creating 3D models. One way is to represent the 3D model as points in 3D space. Each point, or vertex, has 3 coordinates: an X, an Y, and a Z coordinate, to define its location in 3D space. A pair of vertices can be connected by an edge, and edges bound polygons called faces. These faces define the surface of the model. Modeling is all about creating these sets of vertices, edges, and faces.
To create a model, we usually start with a primitive shape (like a sphere or a cube) and reshape it into what we’d like. Individual vertices, edges, and faces can be repositioned. New vertices, edges, and faces can be added to the basic model through simple operations. Two common ones are extrusion and subdivision.
Exploring Clojure as a tool to generate music, visual art, poetry, and dance.
Clojure is gaining traction and popularity as a programming language. Both enterprises and startups are adopting this functional language because of the simplicity, elegance, and power that it brings to their business. The language originated on the JVM, but has since spread to run on the CLR and Node.js, including web browsers and mobile devices. With this spread of practical innovation, there has been another delightful development: a groundswell of people making art with Clojure.
Getting creative with Clojure
Creative Computing combines the power and engineering of the computer with the artistic inspirations of humans. People are using Clojure as a tool to generate music, visual art, poetry, and even dance. This ability to harness technology for creative purposes is both exciting and important. For it not only touches the heart and inspires existing technologists, but it also transcends all barriers. Art is a gateway to bring new people, young and old, from all walks of life, to the field of programming.
Let’s explore some of the areas of Creative Computing with Clojure, and showcase some inspiring examples from a selection of artist/programmers. We’ll look at projects that touch on music, art, games, writing, and even robots.
The O'Reilly Solid Podcast: Danielle Applestone on running a machine tool startup and empowerment through desktop manufacturing.
Register for Solid 2015, where you can see Danielle Applestone’s session — How to make an Othermill: From milk jugs to your door — and much more.For this week’s episode of the Solid Podcast, Jon Bruner and I sat down with Danielle Applestone, CEO of the Other Machine Company — purveyors of one of my favorite personal digital fabrication tools: a desktop CNC router called the Othermill (see a demo video).
Grown out of the Machines that Make project at MIT’s Center for Bits and Atoms and incubated at Saul Griffith’s Otherlab in San Francisco, Other Machine Company launched a successful Kickstarter to finance completion of the Othermill back in May of 2013.
For readers not familiar with this particular type of kit, I’ll go into a bit more detail: a CNC (Computer Numerical Control) mill is a machine tool that can be controlled by a computer to move some kind of rotary cutter (such as an endmill or drill bit) to remove material from a workpiece. This is a type of “subtractive manufacturing” process.
With all of the fuss around 3D printing (known in the industry as “additive manufacturing”) these days, I personally don’t think that CNC machining gets enough attention. Although 3D printing is certainly an exciting technology in its own right, it cannot currently compete with CNC machining in terms of cost, supported material types, and range of applications.
