Disagree.

The "course" may be a facade, but intrinsic structure is helpful. If I'm simply learning by myself, I find myself skipping all over the place and then not completing the work due to being overwhelmed by the amount of material to cover.
Also, before I forget, if let's say english words were being stored, you could have an array of 1..26 pointers (representing letters 'A'..'Z') where each pointer points to one of 26 other similar arrays, representing the second character, etc. This pattern could repeat in memory. Would it be time/space efficient? Depends on the data. Also, this could be combined with the above. Maybe the first few letters of words are stored this way, and the rest are ordered such that a binary search can be performed, as above. Again, depends on data, storage, and speed requirements. Sure, you could use one or more hashing techniques, but then what's the speed/memory penalty, and what's the penalty for collisions? So, there are a lot of considerations to be made when selecting a technique for storing/searching data... there is no one-size fits all technique, as I said above, there's always a better way to do things...
> Steady investment will never give you that.

Sure it does. I've seen lower middle class people become millionaires that way. Of course, one needs the discipline to not succumb to spending it on a car/house/divorce, and the intestinal fortitude to not panic sell when the market tanks.
It depends. At the moment if I see a reddit post saying product X was really appreciated by a user, most of the time I'll believe that was an actual human appreciating that product. But if modern mass marketing is going to be the injection of seemingly sincere product recommendations into reddit threads that will obviously lose value - the bot comment is lower value than the human comment, and because I can't distinguish them all such comments lose value. Similarly for political statements of support.

I'm sure there is potential for extremely useful bots (e.g. such as article summarization bots on reddit) which increase information. I guess it really depends on who decides to set up a bot, and their goals and implementation.

Many people have no clue that automation has come this far and will judge every comment they read online as sincere. If they're actually not, and many are driven by political and commercial agendas, I think that's a bit dangerous, because people will act on them.
Sorry but this absolute nonsense. In reality nobody does care how you host your website snd files, the only thing users care for is the content is always available and fast.
I would say that the ability to recognize true novelty is hard to train without experiencing a fair amount of repetition.
Anecdotally, I've had much better sleep when reading a book just before bed than anything else. Even just cutting of twitter/ screens before bed didn't get me the same kind of relaxed, gentle sleep as reading, say, 50 pages of sff.
> new groups of traders with a low barrier of entry make options much more liquid

Are you claiming Robinhood users are responsible for a significant fraction of option market liquidity over the past year? Because that’s categorically wrong.
Your odds are still likely better than lottery tickets.
> "Freedom from" is just a nice way to say "loss of agency due to oppressive external control".

That is not always the case. Counterexample: "freedom from tyranny", as in "citizens are free from tyranny by the government" – that can hardly be reframed as "the government loses agency due to oppressive external control by the law".
wow, thanks. Better than nothing !
Because as the distance becomes smaller, for unaligned magnetic fields, they stop blending into each other and become distinct fields that eventually push away each other.

As for why two magnets don't pass through each other, as they come closer eventually the alignment breaks down because both poles exist for each atom and end up repelling each other.

Of course, Paul's exclusion principle does play a role, but as long as the two objects are rigid enough you can model this mostly well enough with a magnetic dipole at each atom.

> Taking the opposing side of all Robinhood trades would cause a broker-dealer to lose all of their capital very quickly

Why? This is literally the definition of order flow purchasing and market making. Flow amidst spreads creates profits.

The non-cynical explanation for Robinhood’s flow being attractive is in the law of large numbers. Robinhood’s trades are tiny. That means buying their flow gives one lots of small, idiosyncratic exposures. Institutional flow, on the other hand, is lumpy, which can leave one with a few giant positions.
The hosting provider can still monitor egress, which is what's more valuable anyway. Hypothetically, they could also snapshot the RAM for deferred analysis, though that's usually more trouble than it's worth. You have to trust someone in the end.
Isn't that just whataboutism?
Does one wrong thing makes another wrong thing ok?
I think that title of this article is click bait. The author himself acknowledges that Robinhood is not the only firm that sells order flow data. Infact all the well known so called discount brokerages sell order flow data and have done so for many years before Robinhood came along. In addition to that, all these firms were selling the order flow data and still charging their customers $7 per trade. That practise would have continued unabated had Robinhood or some other startup not come along and provided free trading platform.

Also from a real world perspective, I have tried Robinhood and Schwab market orders and they are very close to each other (most of the times - same price down to the penny). So I am not sure why Robinhood is geting paid more for their order flow, compared to the other discount brokerages.

Also Robinhood is great for buy and hold investment.

If only we had learned something from 2008... But apparently not

(For those who aren't aware) The problem with options is that your liability with them can get bigger than your equity. You buy 10 shares of Newthing.js for $1000 ($100/share), the maximum you're losing is $1000

You shortsell NTJS because they use JS instead of Ruby, but guess what NTJS rose to $200 per share and at the time of selling you need to cover the difference.

(Edit: had conflated put options with shortselling, https://www.investopedia.com/articles/trading/092613/differe... ), as the article says "Because of its many risks, short selling should only be used by sophisticated traders familiar with the risks of shorting and the regulations involved. "

> literally asked my lifestory

That's a result of federal regulation and lawsuits. Investors have a tendency to sue brokerages when they lose money, arguing that "nobody told me stocks could go down!" Hence brokerages try to head this off by refusing to sell to you if you don't certify you are a "sophisticated" investor.
I guess it is a question of definitions, but i think it really is not possible, for the reason that the space of possible test sets includes contradictory sets. So if I ask you a simple question which is not in your training set, like "Does a Quigloth have eyes?", there can be two possible test sets, one where the answer is no, and one where the answer is yes. So a reply to this could be that questions have to be about the real world. But that is then the same "meta distribution" as I mentioned in my previous comment, and not out of distribution learning in the pure sense.
I think you're misunderstanding. I'm not saying users care about infrastructure risk. I'm saying developers do, or at least arguing that they SHOULD

Really, I hate how "single digit growth" is somehow a failure nowadays. Millions of companies everywhere don't even grow year or year - businesses which found their niche, which employ hundreds or thousands of people and which just operate in equilibrium state where everyone goes home paid at the end of the day and it's fine. No one considers those a failure just because their valuation isn't doubling year on year.

It all stems from the same issue: Somewhere up the chain of command, someone promised someone a hard or soft completion date on some feature, and now they want other people to work together with them to meet that commitment, do or die, or maybe do or I annoy you with questions on Slack and make you feel like your financial support, for most people their comfortable existence, is under threat, and the feature needs to be finished by the deadline.

Such is the nature of hierarchical software development (and hierarchical structure in general), whether you call it waterfall or agile, it's the same.

If you do not want to work like this, then you have to find an alternative for yourself, and it probably will not be a "career path", but something individual, that you carve out just for yourself, based on your unique and individual talents.

It's not easy, but it's fun and interesting. And you get to focus on quality, and feel like you are doing good work, and some kind of fulfillment instead of despair and emptiness and like everything you work on will be called "legacy" in 1-12 months and retired and replaced with the next "new" project within 36.
You are correct, hashes are tremendously useful for some types of data...

But, hashes, while tremendously useful for some types of data, are not necessarily without problems for other data, most notably if the data has the possibility of collisions:

https://en.wikipedia.org/wiki/Pigeonhole_principle

https://en.wikipedia.org/wiki/Collision_(computer_science)

https://danlark.org/2020/06/14/128-bit-division/

>"When it comes to hashing, sometimes 64 bit is not enough, for example, because of birthday paradox — the hacker can iterate through random 2^{32} entities and it can be proven that with some constant probability they will find a collision, i.e. two different objects will have the same hash. 2^{32} is around 4 billion objects and with the current power capacity in each computer it is certainly achievable. That’s why we need sometimes to advance the bitness of hashing to at least 128 bits. Unfortunately, it comes with a cost because platforms and CPUs do not support 128 bit operations natively."

So, it depends on the data, and what's being done with it, if the possibility of collisions exist, and what the implications of those possibilities are (perhaps hashes are great for speed, and harmless, if not used with respect to passwords, that is, used in some other place in software infrastructure, they might be the right choice for that place...)
Here's the appeal: I made 4x return in last 3 years "gambling" on stocks. That's far in excess of 8% return from "just passively investing for the long term".

BTW: I gambled on IBKR, not RobinHood (I have RH account but don't use it).

I just don't get why RobinHood is so vilified for the crime of making a fast, usable app.

I use IBKR but their website is just bad. A security theater that makes logging in slow. Sometimes it fails to log me in. Sometimes it fails to show my portfolio. Because, you know, it's only job no 1 of an investing site.
The hardest thing about optimizing is knowing whether something is fast. It helps if you have the another of the same thing that is already fast, or seems so. When you match it, are you now fast?

You are until somebody makes one faster. Then, you're slow again. That is our deal with the Devil: our machines are filled with dodgy gimcracks that often make our program faster, but we can hardly ever know whether it as as fast as it could be, or if some gimcrack that would make it faster hasn't engaged yet; or, often, even how to go about engaging it.

Usually we stop optimizing when it seems fast enough, usually because something else is (still) slower.

It turns out to be pretty simple to make quicksort go twice as fast on current hardware. Standard libraries and compilers generally don't do those things, often out of fear of making a few programs slower than before. People complain a lot more about a slower program than they thank you for making a hundred others faster--if they even notice the latter.
It's my favourite book but it's hardly easy-reading for many people. It's grim and would challenge a few people I bet. I could read writing like that about the desert forever, but not everyone is so inclined.

Yea. But the paper trail argument is a good one. Banks holding minutely detailed info of your purchase history. A PII goldmine waiting to be exploited.
"People also gamble in Las Vegas, no one is stopping them."

If Robin Hood was positioned and sold as 'gambling' and regulated a such, nobody would have a problem with it.

But if anyone doesn't see the maximal hypocrisy in their branding (literally: Robin Hood) and the materiality of their offer, then that's the issue right there.

By 'gravy' the author means 'fish' in gambling terms.

There's just no way kids on their app, are, on the aggregate going to be able to be beating pros esp. on sophisticated things like options trading, but that's the whole point.

That it is maximum at the nucleus is not of much significance. To quote a professor:[1]

> In some ways it does not provide the best description of the electron distribution, since the region around r= 0, where the wavefunction has its largest values, is a relatively small fraction of the volume accessible to the electron. Larger radii represent larger physical regions since.

If you were to do any kinds of measurements, you are most likely to find it at the Bohr radius, not closer to the nucleus.

Yes. Though to be even more precise, the benefits of going outside of regular channels have to outweigh the burden of the regulation.

Do you think some of these issues could be ameliorated by setting out guidelines in the very beginning such as sticking to a simple business model, saying you won’t scale past a small size, and outsourcing business-related work to 3rd party services? Many engineers probably identify with your quotes about “building something no one else has” and “freedom to work on what I want.”

I think many of us would find guidelines like that useful! Because to a corporate engineer drone like myself, starting something small like Pinboard sounds rewarding.
I empathize with the "didn't make me a repeat user" part of the post (at least for typed notes). And being a repeat user is very important to taking notes and making them useful!

The inbox is a place you naturally visit often, and we think that makes it a great place for your simple typed notes. We made Twobird to put notes in your inbox! It leverages the same tools you use for email to help manage and remind you of stuff for your notes. I find it very useful to keep lists and basic typed notes alongside the inbox I'm already working in every day. I know I used to email myself notes -- no longer.

I don't think Robinhood is doing anything wrong. They are making things easy, which it should be. They still need to use the NBBO price, so it's not like they are making things more expensive for traders.

But I've seen this exact same pattern during the dot com boom. Lots of people making a ton of money day trading. This usually culminates in a heavy crash and many people are completely wiped out.

/r/wallstreetbets is hand-in-hand with Robinhood and wsb more than RH is really making a huge game out of this, and it's crazy. I know people that have gotten sucked in by wsb and started buying crazy amounts of options just to lose all their money. If there is a big crash, I hope RH ends up IPO'ing before this, otherwise all their investors and employees will be holding onto worthless stock as trading volumes goes to zero, like it did after the dotcom-bust.
