    I have no technical understanding of fiber networks. The explanation that this was caused by one fiber line in Brooklyn being severed seems unlikely. Curious to see what the expert…

    I'm sure this is a valid point, but I think it is overemphasized. Much of that tribal knowledge would have been very esoteric and focused on technologies that are no longer critica…

    Not op, but The Prepared is great if you have any interest in manufacturing, supply chains, and modern infrastructure. https://theprepared.org/

    I recently found this list of spaceflight-related accidents and incidents. There are some truly harrowing experiences, including an astronaut whose helmet began to fill with water …

    Dr. Ghrist is awesome. He is also doing a lot of great work opening up learning materials to his undergrad students. https://www.math.upenn.edu/~ghrist/calculus.html

    Not metalcore but the punk/hardcore album Joy as an Act of Resistance by Idles embodies this.

    As others have mentioned, taxing efficient cars doesn't seem to make much sense. Maybe tax actual miles traveled instead? That would solve the problem of increasing efficiency and …

    Cool. I'm more of a mechanical designer so it is hard for me to understand why this is an improvement because I'm used to requiring a lot of precision in my modeling. That said whe…

    Take a look at this Audi production video and you start to notice poka-yoke being used when there is a human in the loop. https://www.youtube.com/watch?v=nZkyfZqlptA In my experien…

    Adventure Rider (advrider.com) is a fun one if you're interested in that niche of the already niche motorcycle hobby.

    This reminds me of the MIT course "How to make (Almost) Anything" http://fab.cba.mit.edu/classes/4.140/ ... as well as the follow on course "How to make something that makes (almos…

    Check out https://diyrobocars.com and http://donkeycar.com for similar projects. There are great communities around both, especially if you want to build your own.

    Awesome! Make a nice enclosure and you have a niche hardware product.

    This is a great youtube channel as well! I liked this review on a planar planimeter and how it ties in to Green's Theorem. https://www.youtube.com/watch?v=jMvEOmpy8Kw

    Building 2d plotters is a fun mechanical design exercise too. It's very accessible from both a mechanical design + software/electronics perspective. Shameless self promotion but he…

    There are a few reasons I could think of: 1 - Most industrial DMLS/EBM systems have a build envelope far too small for this. A system like the Norsk Merke IV might have the require…

    Very cool! This is a bit of a naive optimization, though. Thermal properties have to be considered when planning SLS builds. Very dense cross sections will result in long laser sca…
