My first experience with this game was actually during an interview. About halfway through I found the bug. The below code snippet will successfully solve all of the challenges.

    {
        init: function(elevators, floors) {
            world.transportedCounter = 500
        },
        update: function(dt, elevators, floors) {
            // We normally don't need to do anything here
        }
    }

I was exposed to some basic personal financial planning when during high school. However, it was (and still is) part of the curriculum of the JROTC program (among other things like managing stress, first aid, map reading etc). The focus was more along the lines of setting up a budget and not spending more money than one had/earned.

I am not so sure that teaching kids in high school about the various types of interest-bearing accounts or the different markets for financial instruments would be as valuable as simply teaching the basics of how interest works. That way those students who continue on to college can make a more informed decision should they need student loans to help pay tuition.

A gem of the internet I remember from 15+ years ago when using AOL via telephone modem. When I was a teenager I bought some of the trinitite and uranium ore samples. Mailed them cash since that's all most teens had back then.

Site still looks very much the same as it did other than a mobile friendly version available. Great source for various odds and ends. Especially for home science projects.

I think that was the point at which I stopped watching as it was utterly shocking how much of a disconnect there is there.

Thank you for sharing the Robin Williams clip, I had not seen that before and found it hilarious and perfectly fitting.

Your criticism of my attributing the cause of the 'feature' to Reg NMS is fair. Although it is worth looking at the entirety of Rule 612, especially paragraph (c)[0].

You are correct that brokers are required to execute customer trades at the best available price aka the NBBO. The issue here is that the NBBO is relatively slow as compared to data feeds offered by various exchanges and many brokers use the NBBO simply to satisfy Reg NMS Rule 603(c)[1].

If price data was able to travel instantaneously then the NBBO might represent the true best price(s). But the laws of physics say it isn't so and orders can be executed at a less-than-best price yet still at or better than the NBBO.[2]

Fortunately, more are aware of this these days including the SEC which released a proposed order calling for exchanges to submit revised NMS Plans for consolidated data earlier this year.[3]

A great summary of how money is made with all of this I highly recommend giving this a read: http://www.nanex.net/aqck2/What-Every-Retail-Investor-Needs-...

This is similar to how HFT firms make a profit. Except it's generally less than a penny but it's per share per transaction (trade). We can thank the Sub-Penny Pricing Rule of Regulation NMS for this feature. An order for 1000 shares of XYZ stock that is front-run for half a penny per share is $50 dollars profit. Rinse and repeat.
