   hmm. I kinda disagree. For a lot of my relatives, WeChat == the internet. I honestly don't know if any of them have actual email addresses. So the alternative to WeChat is not talking to them at all.

   This is great if there isn't a blanket ban on VPN's, but unfortunately, it won't work in China. I've had next to zero-luck keeping my own VPN tunnels open for more than a couple of days at a time when behind the great fi

   My understanding is that Ben Francis (one of the main individuals behind this effort) is no-longer at Mozilla given the recent layoffs/restructuring. Any idea on how this impacts this project long-term?

   Maybe go read the source code. It's... messy :) UX/UI is also really not the greatest.

   Yeah that + consistency/quality. Depending on the market you’re in, there can be such a variation in finding good trade talent. Installing stairs is pretty specialized so if you can lower the bar + increase quality, seems like a win-wi

   "Prodigious Rate" -- To put this in context, the latest numbers I saw is about $125 per min of unscheduled delay. It also doesn't take that many delays to wipe profitability to zero.

   "Check Airman" -- likely a 3rd pilot in the cockpit, probably for observation/rating. Since this is a 9+ hour ETOPS* flight (over-ocean), there should be at least 4 pilots on board anyways. Airline ground flight ops will also

    Just wanted to chime in to say that the Tensorflow 2.0 Dataset Library is nice for this sort of problem. It supports batching, caching, remote fetching, multiple cpu core splitting...etc.

    Sorry you are absolutely correct. Volume matters a lot, maybe almost as much as weight, for aircraft design.

    Liquid hydrogen has about 4X the specific energy of Jet-A. But yes, the system as a whole isn't great once you consider what it takes to keep the H2 liquid...

    I really enjoyed this write up. Thank you for putting it together. Even as a TF user, I feel it's a really fair assessment of TF vs PyTorch. A quick observation that may not be 100% accurate but still worth mentioning: in some ways TF

    Yeah to actually correct my initial comment, I think pen & paper are still very important & powerful. Nothing quite like deriving Euler's formula on blank pages to see the beauty in it :) But pen & paper shouldn't be t

    I completely agree. By the way, I'm not convinced it's just a U.S. thing. I went to high-school in France for 1.5 years. I also have some exposure to Japanese high-school math. In both contexts, rot memorization of derivation tech

    Aerodynamic simulation is a really tough problem to take on. I'd venture to guess that it's in part due to not having a complete set of theories/equations around fluid dynamics. From what I hear, X-Plane comes really close to

    My time in China doesn't go back that far, but it certainly feels different from when I first went there. Guangdong used to feel pretty chill about that stuff, probably a combination of HK-Proximity and the Emperor-is-Far/Mountain

    Interesting, I was curious. Personally, I feel like the nationalism has gotten a lot worse / uncomfortable in Guangdong in recent years. I don't feel like it used to be this way in anything-goes Southern China.
