The price curve was in sharp decline around that time, easily making "around 2000" +/- 5 years, possible: https://jcmit.net/memoryprice.htm

If you have a csv file that's 10 GB of numbers, and for your purposes float32 is sufficient precision, and there are only 1 billion numbers in the file, then you can read the file into a 4 GB array of float32 with very little overhead beyond the size of that target array. Reading the 10 GB file into memory in its entirety wouldn't help anything; nor would creating an intermediate array of full-precision numbers.

My understanding is most people aren't commenting on this coherently†. The problem that halted Robinhood's GME trades, as I understand it, was that they had insufficient collateral to cover their clearing requirements. Clearing collateral isn't customer money; it's funds that clearinghouses require brokerages to post to protect them from each other. This, as I understand it, is money Robinhood was required to have on hand regardless of whether they had the money from customers to back trades. The amount is based in large part on the volatility of the stocks they're trading, and papers the illusion that stocks trade instantly when in fact the actual trade takes days to settle, during which the price of a volatile stock can swing wildly.

My understanding is that nothing you can do with customer trading funds will mitigate or offset your clearing collateral requirements. Brokerages that want to clear trades just have to have a big chunk of segregated money set aside to keep participating in the market. Robinhood ran out.

† because it's complicated, and there are lots of simple explanations you can come up with that are wrong, and we all have an Internet nerd tendency to fixate on a couple of axioms and derive the rest of the world from them, rather than reading the huge legal documents that set these things out

I love the walrus operator - and use it quite a bit, but, replacing

if hi is None:
hi = len(a)

With:

hi ??= len(a)

Just sounds gratuitous. I'm happy this was deferred.
I'm glad this was deferred because those replaced examples from the stdlib are difficult to read. I've used `or` coalescing plenty of times and definitely prefer it to a new operator.

That said, I really loved using null coalescing/propagation in C#, so I have to assume my bias is coming from wanting python to be more readable.
> Use One Big Database.

It’s never one big database. Inevitably there are are backups, replicas, testing environments, staging, development. In an ideal unchanging world where nothing ever fails and workload is predictable then the one big database is also ideal.

What happens in the real world is that the one big database becomes such a roadblock to change and growth that organisations often throw away the whole thing and start from scratch.
In my opinion the best argument for RDBMSs came, ironically, from Rick Houlihan, who was at that time devrel for DynamoDB. Paraphrasing from memory, he said "most data is relational, because relationships are what give data meaning, but relational databases don't scale."

Which, maybe if you're Amazon, RDBMSs don't scale. But for a pleb like me, I've never worked on a system even close the scaling limits of an RDBMS—Not even within an order of magnitude of what a beefy server can do.

DynamoDB, Firebase, etc. require me to denormalize data, shape it to conform to my access patterns—And pray that the access patterns don't change.

No. I think I'll take normalized data in an RDBMS, scaling be damned.

No more than you should worry about your phone, your toaster, or a boulder suddenly becoming self-aware.

Extremely theoretically, a consciousness could spontaneously form at any point [1]. In practice, there is no reason to worry about this - it's not a likely event. There is nothing about this model (or any other one in existence) that increases the likelihood of it achieving sentience when compared to anything else ever.

That's not true. FICO rates affect where you're allowed to live, what kind of modes of transportation you're allowed to have (many insurers take it into account to decide whether or not to provide coverage), even some health procedures (many dental practices now check credit score), etc...

Options trading in particular is really addicting, like gambling. I’ve had periods where I was completely sucked in, looking at charts and news all day.

Perhaps do the data-cleaning step before loading into a data frame? (Dataframes are, after all, for canonicalized+normalized data, just like RDBMS tables are.)
This is not an answer.

If a currency crashes, not only does that 'really matter' for most regular people who will have some material savings in that currency, it also creates really terrible problems for everyone using the currency.

The value of a currency is in it's integrity over time.

It doesn't have to maintain perfect pricing parity etc. however, it must not just vanish and fall apart.

We can see this with USD and Seigneurage with the Petrollar.

People hold USDs not because they think 'it'll be worth more' but rather, they'll be valuable in the future, because USA won't crash and fall apart.

This crypto stuff is mostly stupidity with bad economics all the way down.

Maybe some day that will change.

It's interesting how humanity will accept this kind of "experiment" when it's a side-effect of something designed to give a little convenience, or for somebody to make a bit more profit. If a scientist proposed doing it on purpose, just to find out what would happen, there would probably be less enthusiasm.

It's also interesting how it's the political "conservatives" who seems to be most accepting of these kinds of environmental changes, when "conservatism" is supposed to be about preserving the way things are now, or perhaps how they were in some recent "golden age" past, as I understand the term.
>with the exception of Iraq, afghanistan, korea, cuba, and vietnam at no real point in these battles was our technological sophistication or "firepower" a decisive capability that led to a victory.

It led to plenty of victories. The NSA straight up hacked into a European telco Gemalto (the world’s largest sim card manufacturer) to steal their encryption keys in order to spy on people in the middle east and the entire world in real time. They most certainly used this data to drone strike people and for espionage.

NK has some decent hacking groups but is certainly no match for US and EU nation-state backed hackers. In fact, I would not be surprised if the US and other world governments have 24/7 satellite surveillance on NK and the few devices/computers that are there are infected with their malware in supplychain intercept attacks.

thanks for reading and commenting. I am incredibly bullish on static typing and static analysis in general. There are quite a few tools that bring these to PHP and JS (I am not entirely happy with PHPStan / Psalm, I am very pleased by Typescript). Before that, I have been using Jetbrains analysis tools.

In web development, I find that there is a certain freedom that comes with dynamic typing that I wouldn't tolerate in other systems software (my other specialization is embedded software), as easy templating and logging are givens.

The fact that so much in web can also be "caught" at runtime (monitoring, logging, tracing) changes the game quite a bit as well, giving dynamic typing a bit more breathing room.
Not scientific and maybe inaccurate, but a quick Google search showed the average Intel employee makes $100k. The shift in social norms where 100x the average employee (of a tech firm, which skews towards high salaries) is considered “basically nothing” is something worth talking about.

As a consumer of all things science but who will never be more than a fan cheering from the stands, one thing I read somewhere stuck in my mind. It went something like:

"We are close to understanding the genome, which will lead us to understanding the proteome. Understanding the proteome will lead us to understanding the metabalome. Once we understand the metabalome, we will have everything: eternal youth, no disease, and everyone can have the perfect body of their choosing."

I doubt any of us will leave to see it, but it's a nice thought.

> "Pure" capitalism would be a dystopian hellhole, and no serious capitalism thinker ever proposed it.

Capitalism is impossible without property rights so assuming you don’t call at least a voluntary system of property rights enforcement “impure” then the very serious scholars like Rothbard, Hoppe, Block etc all proposed it. I’m not sure I agree with them but I don’t think sweeping dismissals or “hellhole” hyperbole are correct either.

In such an event, volatility would go up and markets would begin sorting out new levels.

There's no set logic to the event, as it would be more like a chain of smaller-scope events which currently sit on loosely-connected probability chains, and everything would play out at different time scales.

Trade itself would suffer initially from the volatility-discovery portion. Lots of ups and downs and fears / fear-release events over resources and trade balance.

Day by day and week by week you'd start to see different stories emerge. Interestingly, a lot of those stories will be less about who has how much of what--but about "new fears coming out" about those things. So it will be very difficult to predict, and the story that comes out may in fact have little to do with who really has which resources.

This will be more especially true as things change initially.

Also, big traders and market-watchers currently know, and can intuit, a lot more about China's internals than people may understand. Many of them have spent a lot of time in China or working closely with Chinese banks and so on.

So a considerable amount of the probability of given issues with things like PRC market fidelity is already priced in, contrary to what people may think. Naturally this is also true of the US and various markets. This is one reason why it's a very good idea to check objective levels, directions, oscillations, and so on before entering or changing an investing position during hard times.

Outcomes also really depend on time scales and rely on positional logic. There will be people looking to short everything, there will be perma-bulls, you name it.

Finally you've got relative levels of stability and growth to look at, like given this platform or that, which one seems wis_er_ for your money, not "which one will lose this conflict" so much, since one can't really know that, or the answer may be complex.

If you're an investor, and you want to be smart about this kind of thing, it can be a good idea to look for general positions you want to target that are relevant for your time scope. Get as subjective as possible--your needs, your fears, your expectations. Then fold in more objective states of things, using objective tools. You'll start to see places you want to start to build positions, like Apple under X, Ford under Y, or whatever. You can use tools like simple moving averages and bollinger bands to help sort this out. There will be positions that fit your outlook better and some that fit worse. (This is general advice, always DYOR)

When I think of wave-particle duality, I think its just the expression of 2 facts. Matter waves show interference effects. Matter waves are only ever observed in a definite position, never in a superposition.

But position isnt special right? We never observe a superposition of momentum (move at 2 speeds) either. And neither are macroscopic states, we never observed an (1/sqrt(2))(alive + dead) cat either.

So evolution isn't observation and intermediate states aren't real.
