Caleb sez, "I tore apart components you can find at your local toy store to make a portal gun that actually levitates a companion cube."
I really wanted to make my own portal gun for this. My schedule and my ego fought hard on this subject and ultimately my schedule won. While I feel like I could have built a fantastic portal gun, there’s no way I could have done it in a reasonable amount of time and gotten as nice of results as just buying the portal gun props available at toy stores.
When initially mounted the coil on the gun, I found that the “arms” were far too flexible. I had to reinforce the arm somehow. The option I chose was simply to bend a piece of steel to the correct shape and strap it to the underside of the “arm”.
I made a cardboard model to test weight and size of the companion cube and got the system working on the portal gun.

Scott Edelman writes, “I interviewed George R. R. Martin at a Thai restaurant on Episode 42 of my Eating the Fantastic podcast (MP3), and after I returned home, remembered I’d also interviewed him back in 1993. After digging out the tape, I couldn’t resist incorporating his amusing admission about ‘a fantasy novel I’ve been working […]
Zero-knowledge proofs are one of the most important concepts in cryptography: they’re a way to “validate a computation on private data by allowing a prover to generate a cryptographic proof that asserts to the correctness of the computed output” — in other words, a way to prove that something is true without learning the details.
Retroworks’ $18 decoder rings don’t have much by way of cryptographic robustness (they compare disfavorably to the cipher-wheel wedding rings my wife and I wear!), but they’re not a bad way to introduce the littlies in your life to the idea of habitual secrecy. (via Red Ferret)

Although fully autonomous vehicles aren’t yet allowed on public streets, they are poised to dominate the roads in the not-too-distant future. But before that happens, Apple, Google, Uber, and other companies now investing in self-driving tech are going to need talented developers that can account for the dizzying array of factors at play when a […]
