      > You seem to be always against advising people to make bold choices to pursue their dreams.

      On the contrary, but there is a right time for everything.

      Pretending that a class of graduates has something to learn from a guy that basically is standing before them not because of how ethically he lived his life and how happy he is but because he simply is rich (and therefore successful by our most common yardstick, wealth) is dishonest.

      If you'd go out and find someone that has actually managed to achieve such a state of mind from hardship (say Nelson Mandela) then I'd be all for it.

      My life experiences are one long series of bold moves, and I wouldn't have it any other way but I'm very careful to tell other people to 'do as I do', everything has its price and you have to make people aware of the price before you tell them to purchase the wares.

      I think you are completely misreading me in what I wrote back then, I made it pretty clear in this sentence:

      "Yes, so it worked for you. Great. It worked for me too, 23 years ago, one idle day in July. But that does not mean it will work for everyone."

      To put out the advice to quit to someone without further knowledge of their situation is short-sighted, at a minimum you should spend a good bit of time to ascertain that that really is what's best for them, off the cuff advice like that can be very harmful.

      If you want to know more about my life experiences feel free to read: http://jacquesmattheij.com/ .

      You're welcome to your opinion, but I respectfully disagree. Frankly, I wouldn't be employed if anything you said was absolutely true.

      My firm is hired to implement concepts as working products. I first help the clients decide whether their idea has legs and help them refine the vision. My team builds out v1 over a period of months, and then we generally hand off to an internal team or another firm that will provide ongoing support. We maintain a pool of excellent resources that excel in maintenance projects but don't have the capacity or interest to be architects.

      http://jacquesmattheij.com/The+Starter+the+Architect+the+Debugger+and+the+Finisher was pointed out to me as another recent and good article on the same subject.

      Finally, I assure you that successful Starters are excellent networkers and communicators. They have to be, or else the project will never leave the gates.

      You're right that using an A record isn't great because your hosting provider loses the flexibility of being able to change IP addresses. This article explains it really well: https://devcenter.heroku.com/articles/avoiding-naked-domains-dns-arecords

      My solution is to use CloudFlare for my DNS (it's free, why not?) and use their "page rules" feature to do a 301 (permanent) redirect from domain.com/* to www.domain.com/$1.

      You can see what happens if you run `curl -I maxmasnick.com`.

      dnsimple.com (another DNS provider) also lets you add a "URL" record, which also is a 301 redirect.

      One should be careful with 301 redirects because the are cached locally and quite thus permanent (see: http://www.jacquesmattheij.com/301+redirects+-+a+dangerous+one+way+street). But in this case I think this is what you want.

      These aren't really great for learning about computer vision or deep learning, but are great for building projects that require image classification.

      E.g., recall the awesome project for lego sorting by jacquesm[0] ? He built his own model using Keras and Tensorflow, but you may be able to achieve similar results by using Clarifai's feature to train your own models with no understanding of deep learning. This is great if your goal is to build a thing, like a lego sorter, but not so much if you want to learn how to build a state of the art image classifier.

      If you're interested in learning about computer vision or deep learning, I recommend searching this site to find threads that cover that extensively. Good luck!

      I've thought about it and I believe this is the most likely solution. The vehicle would remain aerodynamically subsonic, but could attain supersonic speeds as the air in the tunnel speeds up. This would also allow vehicles to follow one another without too much separation. Turbo fans can be used to keep the air moving throughout the loop. If enough vehicles are running at full speed, the system will always be "pressurized" as the vehicles themselves will accelerate the air in the loop.

      Passenger/cargo loading would occur outside the loop (a fork) and would be brought up to speed by the power rail and inserted into the loop.

      EDIT - It appears jacquesmattheij agrees with us:

      > That was the intention from the beginning.

      It's so inspiring hearing about people who had unbelievable expectations from the very beginning. I always hear about the opposite – younger Zuckerberg expecting someone bigger like Microsoft/Google/etc to build the "real Facebook" [1], Larry and Sergey thinking they'd never make it to be as big as Shawn Fanning [2], etc.

      Those are all extremely interesting, but I'm much more interested in what goes on with people who call it from the beginning. I'd love it if you wrote a book. Do you have a blog?
