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.

world.transportedCounter = 500

update: function(dt, elevators, floors) {

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.
Perhaps they are talking about Desoxyn. FDA approved for treatment of ADHD. Not saying that it isn't bad but just pointing out there is a comparison to ADHD medications.
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.
As does Psilocybin in Magic Mushrooms. Back when we used to sell the stuff (UK, 2005 or so), we had a small 'lab' (a grand term) run by someone who suffered serious cluster headaches and had gotten involved with us through our selling of 'shrooms.
We used to sell to quite a few people who similarly suffered from the condition, and used mushrooms to treat it - but it was an impossible thing for us to market or advertise, due to the way the MHRA (Medicines and Health Regulatory Agency) dictates what beneficial claims can be stated about retailed items.
On the other hand if you have a migraine while tripping, it's not great. Taking triptanes is, well, risky as their interaction has not been thoroughly researched (i wonder why) and they both do stuff to HT receptors - so it's probably safer to endure the trip and take drugs afterwards. Good thing is that on LSD it is not "you"that suffers, just someones' body ;)
Interesting video, thanks for sharing. Just curious if you have one with tests or benchmarks for the completed build and/or temps at high loads? Would be cool to see :)
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.

Are you sure? I did a quick search and came up with this
>One of the rules in Regulation NMS is a new Sub-Penny Rule: “which establishes a uniform quoting increment of no less than one penny for quotations in NMS stocks equal to or greater than $1.00 per share to promote greater price transparency and consistency. . . . In particular, Rule 612 addresses the practice of “stepping ahead” of displayed limit orders by trivial amounts. It therefore should further encourage the display of limit orders and improve the depth and liquidity of trading in NMS stocks.”
which suggests the opposite of what you're claiming. Also, I'm not sure how you'd even make money this way, considering that NBBO requires brokers to execute their customer's trades at the best available price.
The NBBO ensures you get the best price available on public exchanges. Public exchanges are not the only places where stocks are traded.
If the best price of a stock on exchanges is $25.00, but an HFT can buy it at $24.99 on a dark pool, they could buy it cheaper and sell it to you, and pocket the difference. When they pay your broker for the privilege of doing so, it's called payment for order flow. As a retail trader you have no visibility or access to dark pools.
Aside from dark pools, NBBO updates have latency which may be exploited:
Not matter how they do it, the fact that they are willing to pay your broker to execute your order is proof that they have some way to make money from your orders.
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]
