Notes, 2019-11-18.
I spent some time this weekend playing with Legos (with - and without - my daughter), something that I spent countless hours doing as a child and which I *intensely* enjoy still. I was struck anew, though, at just how much of the experience of building a Lego kit is about meticulously hiding its internal complexity. Lego is intentionally modular, and the delight in building Lego kits comes from observing their modularity and appreciating the way in which structures are build up from individual components.

I'm also finally the proud owner of a couple of basic block kits - boxes of Lego parts intended for exploration and with no specific structure in mind. One of these is at The Prepared's workshop, and I'm looking forward to fiddling with it during interstitial time; I also created a #lunchtime-legos channel in The Prepared's paid subscriber Slack instance, which feels like the most wholesome professional thing I've done in a while.

Separately, thanks to all the companies who reached out for the free job listings offer! I like this experiment :)

The most clicked link in last week's issue (~22% of opens) was a piece about cheap, Chinese made hi-fi audio equipment.
Jobs.
The Prepared is supported by people like you, and from generous support from:


Planning & Strategy.

  • Richard is looking to talk to someone who has experience manufacturing consumer products in Mexico. Reach out to him here.
  • Adidas will close two "speedfactories" in the US and Germany, relocating production to Asia. "Just three years ago, the Bavaria-based group had hailed its speedfactory concept -- which uses highly automated processes to make shoes more quickly, more customised and closer to sales outlets -- as proof that manufacturing jobs could return to high-wage countries." Note, this article mentions "4D printing," which was a provocative (and now largely forgotten) idea championed by Skylar Tibbits in his 2013 TED talk. While Adidas does have a shoe called the Futurecraft 4D, it's actually just a shoe with a 3D printed midsole.
  • A good, and relatable, little Twitter thread on the negative consequences of (mostly B2B) products that are purchased by administrators rather than end users.


Making & Manufacturing.


Maintenance, Repair & Operations.

  • A good, comprehensive guide to compostable plastic packaging. TL;DR: "if recovery is your highest priority, paper mailers are the best choice because access to recycling and composting is much more readily available."
  • Adam Minter on car seats, which are widely claimed (without evidence, by their manufacturers and retailers) to expire. "I figured that Car-Safety.org would have links to studies showing, for example, increased risk between a used car seat and a new one. But I was wrong!...So I wrote back to [retailer] Target and told the company. Hours later, its website language changed again, this time to read: 'According to car-safety.org, many manufacturers recommend that car seats expire around the six-year mark.'...But anyone trying to locate data supporting that recommendation will be disappointed. Car-Safety.org — like the manufacturers who support it — just makes unsubstantiated claims."


Distribution & Logistics.

  • Gazprom's "major projects" page for the Novy Port field, an installation (what an odd euphemism, no?) that lies right about on the Arctic circle. I find myself quite impressed at Gazprom's website, especially as I don't really see the how they benefit from sharing information so attractively; is it just for their (non Russian government) shareholders? Anyway, the photos are stunning/horrifying, and I'm reminded just how good (and uncomfortable) it is to browse sites like Gazprom's in order to remind oneself just how the world works.
  • NASA's 2019-2020 free + open source software catalog.


Inspection, Testing & Analysis.

  • Some *really* fantastic simulated videos of food being cooked, taken from a SIGGRAPH paper. These are totally mesmerizing - whether you're interested in FEA at all, it's super fun to watch a multiphysics simulation of a cookie baking and a loaf of bread being torn in half. 
  • I'm looking for a superior metric tape measure; send recommendations here. Note, dual unit doesn't count - it's gotta be all metric :)
  • A summary of a new working paper which argues that fancy, market-rate housing (think of the glassy condos going up in most affluent cities in the US) actually does "help relieve pressure on rents across the market, including in less-affluent neighborhoods." I'm on the hunt for more writing like this; send it!


Tangents.

  • Kernmantle is a term used to describe modern (almost always synthetic) ropes which contain a twisted core (from the German word 'kern" meaning 'core') and a braided sheath (from 'mantel' meaning 'sheath'). The core provides tensile strength; the sheath protects the core.
Thanks as always to our recurring donors for supporting The Prepared. Thanks also to the following readers for sending links: Andrew, Gabe, Clay, Rich, Gavin, Fabian.

Love, Spencer.

p.s. - We should be better friends. Send me a note - coffee's on me :)
p.p.s. - Whenever possible, we work to encourage inclusivity. Here's how.
