I suspect that a lot of our better skyscrapers will be around in 500 years: once a pattern is set, people like to preserve it.

Yes! Good thing you pushed back on the architect. I have a similar design philosophy that honesty is more aesthetically pleasing than deception. When designers resort to faux materials and structures, the truth still tends to peek through,

Agree. We're working on this. Long term goal is a simple trustworthy digital agent for getting, understanding, controlling your own data. Please contact if interested.

To clarify: keep generating landing pages and MVPs. You will likely find a more promising MVP.

Quick thoughts: - I don't understand the value proposition relative to other cloud storage providers - Hire someone to do your UX (could start with just landing page layout, icons, and color theme) - Selling to developers is a challeng

The UX is missing signifiers to tell me what affordances the system offers. This seems to be a universal challenge with language interfaces like Siri.

What happened to 3D printing (ran and sold a small startup in this space): We realized that the vision of a 3D printer in every house was absurd. Consumer ≠ designer. Amazon is cheaper, faster, easier, higher quality unless I am putting on

Currently work at Jabil building software for managing 3DP at global scale. Can't get into the details on evaluating part quality other than to say that I personally think MJF parts are awesome - completely different thing than FDM. Ju

We use HP jet fusion printers to manufacture end use parts (see https://www.jabil.com/insights/blog-main/3d-printing-reality... ). They are impressive machines, and I'm excited to see the full color ones in ac

This is not correct. We use HP jet fusion 3D printers to manufacture production parts at Jabil (see https://www.jabil.com/insights/blog-main/3d-printing-reality... ) and MJF is quite different from other tech e.g.

This was a well written post mortem and I appreciate Nick's honesty, but it left me with the impression that Walnut closed because the team ran out of willpower. There were a lot of challenges and concerns described, but rather than at

Julia is my go-to language for numerical work. Compared to other solutions I've used like python + numpy + pandas, Matlab, Mathcad, heh even Excel, Julia is a breath of fresh air. Fast, clean, powerful.

I agree with other commenters that if you want to do aerospace CFD, I wouldn't start with CS (if you want to build compilers, sure). This conversation makes me think of physics, which I'd consider the liberal arts of scientific de

Cash is oxygen. It gives startups time and options. Startups are fragile, so those are great things to have on hand. The question is whether money can be raised at acceptable terms. Uber had a lot of leverage because everyone wanted to inve

Refreshingly practical site. This is exactly why I think solar will beat nuclear hands-down. Solar enables gradual adoption, unlike nuclear's power-plant sized step function. Regardless of the actual price in $/kWh, people like do

I don't think the exact numbers matter at all. What matters is that solar is generally perceived to be safer, easier, and cleaner than nuclear at any scale. I feel confident that I could set up my own solar installation safely, and tha

The part quality can be impressively good - the test parts I've seen match or exceed the resolution of typical FDM prints (from ~$2k FDM machines).

I don't understand why this hope is still prevalent. 3D printers are just another tool in the manufacturing toolbox. The sets of materials and structures printers are made from barely overlap with the sets of materials and structures t

I've never understood reprap's cult-like fascination with self-reproducing 3D printers. This is such an absurdly impossible goal that it's more of a category error than a current technological limitation: 3D printers are not

Dollar Shave Club seems like an obscenely over-engineered solution when safety razor blades cost $0.12 each, and a pack of 100 blades easily lasts for 1-2 years and fits anywhere. Shaving is not a new problem.
