Glass immediately comes to mind as having less creep. If you go back to the Faraday, Hertz, Tesla et al days when they were arcing kilovolts across their labs you’ll often see them using glass insulators. Some ceramics and Teflon too.

Simply because you’re both right. One is correct in that repeated exposure to an allergen can upregulate IgE production, especially in cases of severe allergies like bee stings or peanuts. This is due to the immune system's sensitizati

I once read an off hand comment[1] from a dental scientist on Reddit that NovaMin® (calcium sodium phosphosilicate) was shown with strong evidence to reverse tooth decay and promote remineralization but due to complex licensing issues was m

I fasted for a while (40 days) and definitely noticed a slowdown in basal metabolic rate towards the end. Initially I was around 2,600 calories but towards the end dropped to 1,700. Engaging in intense physical activity after ending my fast

For an extended read, you may try "King Rat" by James Clavell - same author of the current hit show "Shogun". The book is set in the same Changi PoW camp where the author was held during WWII. The character Lieutenant-Co

No purple, no stiffeners, 12+ day turn, 4mil thickness(!), but yes I understand one can wait and get boards more cheaply from OSH or shipped from China. I’m more trying to address the “hey let’s go to the factory this weekend and try someth

Most of the comments strongly advise against moving to Shenzhen. Having prototyped in both places I’ll make some arguments for. I’ll preface it’s only worth it if you’re beyond the limits of what American facilities can do and it's a s

I’m always surprised no one talks about the top of funnel for ATC controllers. As a pilot, ham radio operator, and operations enthusiast I considered it as a career change at 35 but it’s an impossible field to switch into. In particular:

I’d love to see the default examples seeded from the “best comments” section [1]. Three of examples on the current home page surface some toxic threads (“llm waifus”, “internet of shit”, and “AI Doomers”)… which while controversial aren’t a

I love how varied the responses are. I’ll play… Walk every aisle of your local Best Buy or MicroCenter. Do a mental calculation of how would this hardware product be 10x better with (present day’s) latest software trend. Eg can I make this

It was an open source crowdfunding platform that raised $100m collectively for projects that used it. Ie Lockitron raised $2.2m in presales with it. Tile raised $2.6m in presales with it. And so on. Unlike Kickstarter it did not take a 8-10

I’m referring to the period between 2010 and 2013. I suspect we were both privy to a lot of conversations we can’t share here. I am familiar with those processor conversations. GoFundMe didn’t pivot to primarily medical fundraising until la

Kickstarter was and will always be beholden to their credit card processors and a painful lesson in picking one’s payment provider carefully. It’s your payment processors fraud risk department which dictates which products and services you

Unrelated to engineering but the recent rebrand to a dead butterfly logo[1][2][3] may be off brand for a platform wishing to communicate a more open, social Internet built on first principles and scientific rigor. [1] https://www.

It was a strange read for me and the first time I’ve felt out of touch with the new generation of writers. The research quality is inconsistent—impressively thorough in some aspects yet glaringly lacking in others. The critique of 19th-cent

Yes and no. A benefit of those same restrictions means TSMC is building foundries in the US for a change. GaAs sensors are awesome. Combine those chips with ML optimized compute on a silicon interposer and drone warfare gets a hockey stick

Unlike sending engines for cryptographic cyphers across nation state lines, night vision is absolutely one of those things ITAR cares about. And the number of loops holes and exemptions Audi had to apply for made the project financially unp
