To do that would be to presume I doubt the validity of your claim (I DO believe what you said).

I specifically asked how overfitting applies to a simple procedural technique, rather than a multi-dimensional method like a neural network.

Trying myself, and losing money, doesn't explain how overfitting applies to procedural steps (as I said, my ML is rusty)
Yes but all of humanity? All? It’s like looking at murder rates and hating Humanity because it murders despite the majority of the global population having not even touch a Gun before.
I hope they charged them A LOT of docking fees
> OCaml and F# are two examples of functional languages

Both OCaml and F# are multi-paradigm languages that have FP features, but are not restricted to FP. The support for mutability comes from their imperative/OOP ancestors, not from FP.
There is no spread when you trade at the open and the close. There could be slippage (you can create a market impact) but it would be minimal on sectorial ETF because they are extremely liquid.
What’s your favorite resource on Drucker? I love re-reading his book “The Effective Executive”.
I wouldn't say so. Nearly every country that borders the South China Sea is having their sovereignty trampled on right now https://en.m.wikipedia.org/wiki/Territorial_disputes_in_the_...
His point seems to be that progress isn’t accelerating faster than it has previously, and there’s already a long history of computers overtaking human performance at various tasks for decades—chess, go, handwriting recognition, and so on—so which task is the final step to reach singularity? If there is no single moment, then each advancement is just part of the normal expected progress like all the others before it. And if the pace of progress isn’t accelerating faster now than it ever has before then there’s really nothing special about this point in time.

I suspect that computers will be vastly superior to humans in many, many tasks long before we acknowledge that the singularity has already happened.
I don't think this is a good argument at all. They'd have to be "technical" enough to write down 13 words when instructed, and they'd have to be "smart" enough to happen to be early.

So basically no technical or smarts are needed to get to this situation. If anything this suggests the person is your fairly average "dumb" user.
As I read it, the strategy never goes long -- it's always simply short one ETF. The bad cases look like "one sector consistently outperforms", or "leading sectors have bull runs of consecutive days before losing steam".
The problem isn't that Apple should be responsible and isn't, the problem is Apple is extremely paternalistic but in a way where it gets all the powers but skirts all the responsibilities.

If the responsibility is too impossible (and I'm fine saying that it is), then their paternalism shouldn't be called out and their reputation knocked down a rung or two. Instead, they get to keep a reputation which is far better than the other megacorps'.
It will short it for one market day and then ignore it.
This would all be short term trading, so it would be counted as ordinary income, which is bracketed.

Using semantic HTML in web authoring is not the same as the concept of the “semantic web” [0].

The article makes it clear what it is about and it’s not about the goals of the semantic web.

If one of my algos makes money, I'm happy to pay.
As previously said, this is probably just mean reversion. It’s a commonly used signal that appears to print money all the time, until you take transaction costs into account. If you want to have even more fun, try back testing this same idea on intraday data. Your performance should look phenomenal, and your Sharpe ratio should be well above 10.
Would have been easier to ship by boat, even without dismounting it, since it’s the cheapest transportation. But it seems I’m wrong, since they didn’t do it.
A simple example that still constrains the puzzle to human abilities (but also makes it less universal) might be this. Rather than diagrams/images, each puzzle consists of two groups of short depictions of two people interacting. The differences are in the relationships, emotional states, or modes of expression. That kind of judgement requires different perception, intuition, knowledge, and so on compared to the puzzles based on shapes. Probably a lot of people who were good with the "standard" Bongard problems would struggle with the "interpersonal" variety, and vice versa.
I have eaten insect flour chocolate brownies in a restaurant. They taste similar to a regular brownie, but are a little more gritty. If that slightly unpleasant texture could be removed, and the base ingredient given a more palatable name - eg sky chicken - then the flour could definitely take off as a food staple IMHO.
Easy to say when you are retired and have $. Everything is getting more expensive. Healthcare especially. having more money and the peace of mind that comes with it is important. I would rather err on the side of earning too much than run out and be stuck.
There's no overfitting in the traditional/model sense here. This is a pretty rudimentary momentum strategy (long best performers). Implementing this on any kind of scale would be expensive to trade since it rebalance's daily.

For momentum, Jegadeesh-Titman paper is much of the foundation for these types of strategies, if you're interested. But as others have pointed out, the "smart money" saturated this trade decades ago.
Are you seriously recommending that people disable security updates as though that somehow makes anything better?
Courses of action are plenty. These are foreign fleets illegally fishing territorial waters, so there's no real reason for authorities to object to enforcement.

In this case, the problem is enforcement, which locals on here seem to think is related to coast guard resources and/or corruption. I would hazard that its an issue of will and/or competency, in this case.

Overharvesting in international waters and overharvesting legally within territorial waters is a different issue. The actual solution, IMO, is a blanket ban with certain exemptions. Fishing is very political thought, and constantly underestimated by politicians and MOPs who naively wade in. Financially, fishing is not that big an industry. It does represent a livelihood for a lot of people. It also has huge cultural significance, literally an ancient way of life. For everyone else, it has some cultural significance, culinary significance... so a touches a lot of people. It's genuinely a big ask. I support a ban, but underestimating effects on people is a recipe for failure, and bad blood.

Commercial, terrestrial wild harvests at industrial scale famously wiped out US bison herds very quickly. One notable example of many. Inland fisheries, especially salmon, faired similarly. Bans have been far more effective than controlled harvests. Two big examples are Cod and whaling. Cod fishing is one of the oldest modern regulatory history in fishing... but Cod never recovered. Whaling OTOH, most species that were not depleted entirely have recovered. The ban worked.

Oceanic fishing is similar to terrestrial harvests and inland fisheries , just bigger and with the added difficulty of requiring international coordination. We can't harvest wild stock sustainably at a commercial scale. Perhaps it's possible in theory, but theory has rarely proven out in practice.
I write huge scripts with bash. I know many of the pitfalls referenced on that list (and more), but this a great resource for teaching others. Thanks for sharing it!
There are still parameters here.

On {day/week/month} n, determine which {n} product(s) of {product brand}'s {product type} of {underlying asset type} gave the {highest/lowest/some of each} return.

At n + {a number} {days/weeks/months} go {short/long/some of each} at {market price/limit price} at {market open/market close/time in day} the previously identified securities. Close your position on day n + {a number} afterward at {market price/limit price} at {market open/market close/time of day}.
Honestly, probably nothing. There is no will to do anything about increasing Chinese belligerence and I suspect a fair amount of perks offered by China to keep it that way. Look at the silence about the Uyghurs. Nobody cares about them. Why would they care about some fish? (Granted, people often care more about fish than human beings.)
this might be true for certain graphene stories (or paid advertisements where it's covered up who paid for those) but please don't say that "journalists" (meaning the whole group of journalists) have "zero morals". Because (real) journalists at least report more or less about the information that they receive and (yes) interpret it, that's better than zero morals (how much can be argued). Zero morals are what you find with certain politicians (or social media users or paid-for-studies-by-cartels) that pull their stories out of their behinds with no accountability whatsoever. Journalists still have a certain higher standard. And we shouldn't neglect this or say otherwise because this would lead to further erosion of trust in media. People should trust news sources more than social media posts because real news sources are still (!) more trustworthy than social media posts. Critical reading and thinking for thyself should be on the agenda everywhere, though.
Oh i see LOL, thank you!
Yes, the experiment conducted on the submitted website looks a lot like the "Storm 1" example situation in Figure 3 on the page you linked to.
This resonates well. I have a hobby software podcast (https://softwareatscale.dev/) and the most common question I get asked is around how I'm planning to monetize it. I've had unsolicited offers from acquaintances to partner up to set up merch deals (?) and even NFTs to sell episodes.
Was lithium the purpose or are there greater issues at hand and Bolivia happens to have lithium deposits?
It sounds to me as if Apple is doing a relatively good job.

The article didn’t give total volume numbers, but 48M USD seems like a drop in the bucket. Only 2% of top 1000 apps? I’d love to see the numbers but I doubt the Play store is even in that ballpark.

Like everyone, I would love to see a world where no one gets scammed. Unfortunately there are humans involved so ¯\_(ツ)_/¯
Sorry guys - it should have said: All the way to the moon.
If you paired it with a "long everything" strategy (to reduce risk or whatever -- fewer eggs in this basket) the net strategy is something like "buy everything except yesterday's top performer", which can be done quite cheaply. Though fees on sector ETFs are high relative to broader ones.
Yes mine let's me put in a limit. I have set it to a low €500 since I rarely do large purchases in webshops.

At the end of the day people are responsible for not doing business with shady stores or people. But the idea that a single QR code can empty my entire account is sobering...
Right on point -- it's called "alpha decay".
Yup, I have been using this extensively. Paul's notes are something I forgot to mention-I referred to them almost daily, back when I was taking the equivalent of Calculus 1, and they're still very useful now that I'm taking differential equations.

Unfortunately, this doesn't quite work on OpenStax-I can't get LaTeX, all I can get is MathML, and that's not very easy to read. There's a way to navigate the math (using something called mathplayer), but it's quite inefficient as compared to LaTeX, specially as I go into higher math. The books are still very, very good, though.
Interesting... what do you mean by this bit?

> Implementing this on any kind of scale would be expensive to trade since it rebalance's daily.
Let's see. Science? Nope. History? Nope. Exercise? Nope. Reading? Nope. Writing? Nope. Foreign languages? Nope.

Current events? Yup. Just bring a newspaper to class.
Argentina has it's own SARs to do the same.
The article, and the comments on the article here, and even the ARIA documentation itself as quoted in comments explain why semantic HTML is important to accessibility. "Yeah, but it doesn't yield something interesting SEO-wise" leads us to make web sites that are trash fires, and not just from an accessibility standpoint.
It might be instructive to flip the question around: what would Nintendo sue for? For which works of authorship is Dolphin infringing the copyrights? Which Nintendo patents or trademarks does Dolphin infringe? If the angle is contributory infringement based on users running illegally copied games, how does Dolphin fail to pass the "substantial non-infringing uses" test?

The only emulator project I know of that was apparently successfully stopped by Nintendo wasn't an emulator of a Nintendo system at all. It was actually a Neo Geo Pocket emulator that had "Pokemon" in its name (for stupid reasons that are not relevant to this discussion) and was threatened for trademark infringement on that basis.
Yep, the conflation of points into time-spent is a perversion of Agile and creates an incorrect metric for value delivered to the user.

If you look at points as a lagging indicator of time estimation, it’s much more valuable as you can establish trends and look at those trends versus team strength, etc. Additionally, if you use the ratio of stories, bugs, and chores as a leading indicator of product/team/codebase health, you can make intelligent decisions about when larger refactors are necessary. If you find yourself spending more and more time on bugs, you might want to take a step back, assess the cause and invest in fixing it.

Basically, getting rid of timeboxing, establishing team SLOs on portion of work (such that breaching your error budget requires refactoring/paying down tech debt/halting delivery of new value), and ensuring points are only assigned to value-producing work, would result in a better process and clearer outcomes and impact.
I feel like having a Pricing link in the header would indicate that it's not free. The "100% free" part is in bold and there is just a few lines of text.
Well hey now, I think people are too quick to call gas light these days, such that the term is losing some of its meaning, seriousness, or utility. The people you're talking to (at least in this thread) are stating their own beliefs with their own evidence. No one (that I can see) has directly attacked your self confidence (unless you're extremely sensitive) or attempted to convince you that you're in a different reality to exert control over your personal self expression, esteem, or confidence. Gas lighting implies direct personal attacks and what I see here is thoughtful interesting, but serious debate. I would say that you saying you're being gas lit here is strong indication you truly do not understand what that term is.
Despite the sad loss of the ACLU as an institution that cares about civil liberties, we can remain hopeful due to other organizations like FIRE.

I'm in the same boat, making electronic music as a hobby. I don't think there's anything wrong with wanting fans of your music, even if you have a day job and have no desire to make it a career. As fun as the creative process is, if you're making (good) music there will probably be things about it that you don't enjoy, whether that's sound design, tweaking effects chains to get something to sound right, banging your head trying to figure out why your track doesn't sound like your reference, mixing, mastering, etc. If you're putting in that effort, it is nice to see some validation, even if it's just in the form of "likes."

Promotion is a different story, though... I don't think it makes sense to throw real money (aka more than like $20 on Submithub/Labelradar, which I consider more paid feedback than promotion) for a release unless you're planning to get an actual return on investment there. At which point it crosses the line into "hustle," for me.
For example, without something like Node, you cannot even open a file. I consider this a very basic requirement for being "general purpose".
Or some kind of tech like microwaves that causes the fisherman (or the fish?) to scatter.
Oh, that's very good to hear! I'll definitely get in contact. I won't be able to, for the next two months or so, but after that I should have some free time when I can test/contribute with code/whatever else is required. (Hopefully, if this gets done, publishers that use LaTeX for typesetting might automatically offer accessible PDFs as well.)
Free speech is how civil rights are won. It is a prerequisite for a positive change.
Of course. Some people can do that and nobody I know of has ever said anything different. But what is also true is that some people can’t do it, sometimes people are trading their lives away for only basic sustenance and no job security.
Unrelated: How does one find a mentor/mentoring group? I've been thinking about it a lot lately, how for the first time in my career I'm without someone I would call a "mentor" and how that's probably not great for personal growth. It seems artificial to look for someone to call a mentor, as opposed to happening upon a person that you look up to and makes you feel inspired to grow. Can you shed some info on how a mentoring group works?
Does the endpoint on Yahoo Finance just download the CSV file? Could use a node HTTP fetch go nab the latest CSV, check if it's new, if it is throw it in the data set then run the algo.

I'm not familiar with Yahoo Finance so I'm not sure how feasible this is.
When I'm interviewing, I love to hear about someone's homebrewing or swing dancing, or bread baking, or homeassistant setup, or whatever. Not because it's a "hustle" but just because it's a sign that they a) are an interesting person who gets into interesting stuff, and b) are someone capable of following through. Putting this stuff on your CV invites that conversation in the interview.
It's not that bad personally, I can and do do demos and show code. Just have to do the chore of writing a paper, but otherwise in academia people are quite free to do what they want. I find it to be more a disservice to society that funds academia.
Concerning the mention of closures:

… it does seem to me that … OOP represents the discovery by the mainstream community that it is a good idea to associate code with data, but, since they still don't know how to do closures, they have bodged it.

So the president of a country:

- Whose minimum wage is between $113-$242 dollars per month [1]

- Where 26% of the population is living on less than $5.50 per day [2]

Wants to use a digital store of value, as a means of exchange, whose transaction fees have ranged from $6-$60 in the past 2 months [3]

How is this anything except an attention/headline seeking PR move?

This is the layman’s explanation I was given to me by my finance professor in college:

In the extreme: If you take completely random price fluctuations and plot them on a graph then review them, they are no longer “random” - they become fixed because they’ve been recorded. It becomes possible to look for patterns, of which there will always be some (that’s the nature of randomness). It doesn’t matter the time scale. So your system that works over 20, 30, 50 years of past data is just fitting to the randomly-generated but not-actually-random once recorded set of data. From now into the future, the randomness will re-emerge and the system will fail.

Another way of thinking about it: imagine you click a button to generate a random time series over 20 years, then build a trading algorithm based on that single click. Great - it works! Now click again and regenerate the entire series and see if it still works :)
Average return is just one statistic. You can earn an arbitrarily high daily average return by taking an ordinary strategy (e.g. buy and hold the S&P 500) and applying large amounts of leverage. Returns will be great until the strategy blows up.

What was the volatility of this strategy? When backtested on the historical data, what was the maximum drawdown? What happens when trading costs or slippage (buying at the ask, selling at the bid) are modeled additionally?

252 trading days times two trades per day (short sell at open, buy to close at close) is a lot of trades, and execution quality will be very important.

Does this strategy hold up with week-long holding times?
Major omission: learn basic accounting. Know what terms like equity, debit, margin, revenue, profit, liabilities, assets, etc., really mean.
To add to this, the App Store clearly markets security and trust.

These are the very first words describing the App Store (https://www.apple.com/app-store/):

"The apps you love.
From a place you can trust.

For over a decade, the App Store has proved to be a safe and trusted place to discover and download apps....And a big part of those experiences is ensuring that the apps we offer are held to the highest standards for privacy, security, and content."

The page then says this about security:

"Security for every app.
At every level.

We ensure that apps come from known sources, are free of known malware, and haven’t been tampered with at the time of installation or launch."

And this about trust:

"Apps must adhere to our guidelines.

When you download an app, it should work as promised. Which is why human App Reviewers ensure that the apps on the App Store adhere to our strict app review standards. Our App Store Review Guidelines require apps to be safe, provide a good user experience, comply with our privacy rules, secure devices from malware and threats, and use approved business models."*

Really interesting - Skruv looks really cool! I think the use cases are slightly different, where million tries to just be a virtual dom that other libraries incorporate, skruv seems to be a JS library (correct me if I'm wrong).
