Notes.

None.

Wayfinding.

• A pretty great interview with Matt Haughey, the founder of MetaFilter, about the dangers of depending on search rankings and the pleasures of working for someone else.
• An analysis of the words that people use in their YC applications.

Building.

• This "investigation" is a bit lightweight, but it's still the most info on Velo3D (a startup working on something in metal AM) that I've seen.
• IBM put a 5-qubit quantum computer online, and they're  letting people play with it.

Logistics.

• 538 on how NYC's elevators define the city.
• Things you learn from flying a 747.
• Google Maps' design has changed over the past few years. This analysis ignores some of the differences in usage between paper maps and digital ones, but it's interesting nonetheless.

Evaluation.

• A good teardown and explanation of a ATM PIN scanner.
• A retrospective of MakerBot.
• A (much more upbeat) retrospective of A123Systems.

Stuff that doesn't fit into my dumb/arbitrary categories.

• "Australia to destroy alien carp by releasing herpes into rivers."

And.

How to rebuild the Canarsie Tunnels.
