The article is vague, but I suspect this is referring to FMVSS-127 which makes certain active safety features mandatory in 2029 and also increases the difficulty of some required t…

AV’s with enough sensing are generally quite good at stopping quickly. It is usually the behavior prior to the critical encounter that has room for improvement. The question will b…

This is a side project inspired by HN comments. YouTube has great content (Mark Rober, Smarter Every Day, etc.), but also a lot of junk. YouTube Kids wasn’t any better—my 8-year-ol…

Sharing a side project that was inspired by some here on Hacker News. Many parents realize that while YouTube does have some really good content (ie. Mark Rober), it also has a lot…

You can watch without a subscription. But unless you have YouTube premium, they can inject ads into the videos. I don’t add any ads.

Thanks! Any and all feedback always appreciated. It’s been fun pulling together.

Yep. Not great data science, although the conclusion is likely true-ish. Also I suspect big urban vs suburban vs rural differences in current EV buyers given range and charging fac…

Many times, the best solutions are very simple. These often seem obvious in hindsight, but were at the time either non-obvious or dismissed prematurely.

Your explanation is so much more succinct than the article! I believe buried in there is one other factor that is somewhat related: - reducing friction helps drive more legitimate …

Totally not equivalent in my view. In traditional interviews, I’m also interviewing the company to see if I want to work with these people. A take home assignment only shows me tha…

Despite all the caveats / problems on statistical significance and methodology, 1 key takeaway: “Unemployed” engineers communicate better than those at Uber, Twitter, Amazon, and G…

Was wondering how much temperature matters, and thinking probably a lot. Do I even know what room temperature white wine tastes like? Not really.

Wow, so many replies that boil down to “because typing is better, you should just type”. This is fairly insulting as RSI’s are very much a real thing. Does this community also thin…

+1 anecdotally I think it is often a combination of factors. And once you start looking/ exploring and realize you can get a comp adjustment, then that becomes an easily quantified…

Super helpful. I didn’t know about individual 401k’s. Thank you!

We will at some point have vaccinated the true believers and be left convincing the rest of the population to get their shots. From that perspective, taking action to demonstrate t…

The Office has already solved unified notifications... WUPH! https://youtu.be/15whn40EQww Edit: or perhaps anti-unified...

I believe helium is used due to it being more effective than air at removing heat. Vacuum is significantly less effective (as in, no convection in a vacuum)

Yields will suffer with current DUV process which must be multiple, multiple patterning. The mentioned switch to EUV reduces multiple patterning and should improve yield. But EUV h…

Exactly this. Bitcoin as it stands is the definition of inefficient. Consuming vast amounts of energy for no purpose. Yes, there are ever-changing explanatiins for Bitcoin's useful…

Just for my own understanding. .. if an article is interesting, but title is click bait, is it really considered better to make up my own title vs. use the author's title? I could …

It strikes me that SW is a key reason for any shift toward a toy-first mentality. Most of the arguments in the article make sense when a (SW) product can be rapidly iterated. Physi…

400 lbs capacity for passengers / cargo is in line with an R22, a common 2 seater helicopter (389 lbs for Pilot, Passenger and Baggage). However the SureFly situation is likely wor…
