If they had simply removed the offending line (or, indeed, set a preprocessor flag that was provided explicitly for that purpose) it would have been fine. The problem was that they also removed a similar looking line that was the path providing actual randomness.

Those antibodies do not last forever. It is my understanding that the lifespan of antibodies is largely determined by the type of virus they are for. For example, luckily the antibodies for measles and polio last decades. On the other hand, antibodies for rhinovirus and coronavirus last months not years, which is part of the reason why you can have more than one cold in your life.
Also there is something to be said for a market where the customer brings the product to your location for inspection, and whose product is considerable faster to inspect more rigorously than a house.
Also the products within that market are much more uniform and share several unifying characteristic across even different makes and model so its easier to learn a good and accurate pricing function.
That gives them a lot more cycles to improve their algorithms (both human and machine based).
Plus when CarMax were starting out they likely did so with a bevy of folks already experienced and profitable at buying and selling used cars at a profit who had the systematic knowledge of how to do so in their heads.
It then was simply a matter of building up customer goodwill by focusing on another metric customers cared about, taking a perhaps slight loss to avoid the risk of being considerably ripped off by a savvy local dealer and saving oneself the anxiety induced by high pressure sales tactics.
Having said that I think Zillow could still be quite successful in this endeavor however from my experience they didn't deploy their trading algorithm in a prudent way, they massively over-traded an untested by the real world model, they trusted their paper trading (backtesting) way to much, and they didnt focus on the nuts and bolts of building a successful market making system: making actual money over and over at small size and ramping up size as your empirically demonstrated pnl grows.
Also putting trading aside they didn't have to be a flipper, they would probably naturally be more fit as an exchange+ or intermediary that provides exchange type backing and reduces the friction in buyers finding sellers, taking on risk by only making an offer when they have a bona fide buyer for fixed or % fee, but glossing over all the hassle of two people who dont know each other making a large trade. Offering services like if you dont like the house you just bought through us we will help your sell it at a cost proportional to renting no questions asked.
Zillow hasn't gotten to the point where they provide that, but theoretically they could. You could drive around with a Zillow agent and see their 50 homes for sale a lot quicker than coordinating with 50 random sellers.
Before that I was experimenting with using it as a custom shell for running commands inside a web application. In that use case it was a bit more challenging because I had never written to an actual tty before (ansi escape codes for coloring log files has been about the limit of my experience). For that use case I just really needed to send and receive text. I ended up using this library [ https://github.com/wavesoft/local-echo ] to smooth that process out until I could learn about how to do things properly.
Are any suggestions on:
1. where to learn about how ttys work to do things the right way, or
2. suggested libraries like local-echo that can wrap over some of the trickier bits of just getting text on the screen?
Thanks again for maintaining such a great & useful library!
2. The library you mention is the one I'm aware of, I have a WIP for building a basic shell in JS that I will probably open source eventually if I have the time.
Xterm.js is really impressive in what it can do, but it was pretty tough to get started with as someone who just wanted to pipe shell input/output over HTTP requests to a server. I realize streamlining that usecase is probably out of scope for the Xterm team, but I think there's a space for either some tutorials or a higher-level wrapper library
Probably regional though.
It depends on where you live. In downtown Vancouver there were arrows at each intersection telling you what directions of travel were legal.
Moral of the story, do you think most humans would do a better job at this intersection than the Tesla did?
However just beware that there can be a decent performance hit from having a lot of box-shadows.
