1. Your idea is probably not identical. You execution almost certainly won't be. 2. There is usually room to compete. 3. Innovations often take root slowly and need a network of collaborators and competitors to nurture them.

If you made a kit and put it on Kickstarter I’d buy one. Just sayin’

New comment by jtraffic in "Forget everything you know about 3D printing – the ‘replicator’ is here"

jtraffic — Fri, 01 Feb 2019 13:37:38 +0000

There are subtle differences between 3D printing types that seem at first to be the same.

Stereolithography is horizontal, one layer at a time, and uses photopolymerization (that's Formlabs). (Also Digital Light Processing is close but distinct: https://formlabs.com/blog/3d-printing-technology-comparison-...)

Continuous Liquid Interface Production (CLIP) also uses photopolymerization, but pulls the object from a liquid bath and uses a buffer zone. Still horizontal slices. The upshot is it's much faster. (Carbon 3D is the company behind this.)

The method in the article uses photopolymerization to solidify the object as a set of slices, but the slices are not horizontal.

The big drawback to photopolymerization is it only works on certain resins which can often have undesirable mechanical properties (high elasticity or brittlness, for e.g.) Potentially this method could be a way forward in that respect, because you might be able to put structural materials in the resin solution and end up with a composite. It seems easier to do this way than with CLIP or SLA/DLP, but I'm purely speculating.

I strongly suspect it’s intentional, to get more clicks. I find it annoying and wish there were a way to push back.

Note that many people still use HMC without a closed form for the gradient, via approximation. In fact, Stan (http://mc-stan.org/) automatically approximates the gradient by default if none is given.

Specifically this is about what business customers of AI startups report about the impacts of AI adoption. Main result is for professional positions it creates more than it destroys, reverse for manual labor and clerical

>Auto executives say they need to avoid a nightmare tech scenario that’s become a common refrain at industry gatherings. They don’t want to become the next “handset makers”—commodity suppliers of hardware, helplessly watching all the profits flow to software makers like Apple

Weird comparison since Apple has always made the lion’s share of profits from hardware. Also interesting contrast between big automakers and Tesla. I see Tesla as being in the hardware biz primarily

New comment by jtraffic in "To Change Habits, Try Replacement Instead"

jtraffic — Wed, 28 Mar 2018 01:18:23 +0000

Thoughts and habits are related, but they aren't the same. Interesting counterpoint to the replacement theory of kicking bad habits: https://www.nirandfar.com/2015/04/bad-habits.html
