You know that landlord who tried to keep your deposit by dinging you on everything, especially normal wear and tear?

Yeah, I've caught managers doing the same thing. I may have opportunity to call them on it coming up.
The market price is (basically) the highest price that someone else is bidding to buy at, so your offer to sell at that price guarantees there is a buyer because the buyer's bid for stock at that price is already there when you place your offer to sell.

It can get a little more complicated than that though -- you might be trying to sell 1000 shares and the highest bid might only be for a quantity of 500 so the "market" price for your first 500 shares will be different than the next 500 (unless there are other bids at that same price, which there often are but there's no guarantee on the volume you'll be able to sell at that price).

And that's why they call it a stock exchange... it's just a bunch of people (and companies) making bids and offers to "exchange" stocks at difference prices. When a buyer and a sell agree on a price, you have a transaction (trade). Your offer to sell at market price is just an agreement between you and someone else willing to buy at that price.

(the example doesn't feature primitives calls, not because they don't fit — a primitive call would be <primitive: xxx> — but because their use case is extremely specific to implementing a system).
It comes at the cost of genuine content, though.
My view is that all programmers produce roughly the same amount of bugs per hour, it is just the bugs per feature which differ. Of course bad programmers can spend a lot of time fixing bugs as they go making the end result have few bugs, but still the main time-sink is fixing all of those bugs.

So to become fast, learn to write code which is very easy to verify that it works. If you get surprised when things work the first time you try then you are not fast.
This resonates with some of my experiences.

When I had a corporate job, I worked in a large glassy building that wasn't a skyscraper. It was initially one story -- though tall for just one story because it was industrial scale and held more than a thousand employees (about two thousand, at least after the addition).

The one story building reflected the sea of blacktop parking lots around it and appeared ominously black.

They added a two-story addition to one end and moved my department there. It became clearer that the building appeared to be ominously black because of what it reflected. The taller part reflected the sky while its base still seemed ominously black.

It became even clearer that this was so when they built a three-story building next door to house the IT department. That building mostly looked like floating clouds and blue sky. Very little of it seemed visually heavy and ominously dark.

But they were equally hard to mentally process. It was hard to comprehend these buildings whose appearance morphed based on what was being reflected. It was hard to figure out where they began and ended, what they were made of, etc.

It was not only disorienting, it was disturbing. It was a bit like working in a fun house mirror.
True, but it's a lot of work with no reward for the reporters.

Quoting the prerequisites:

“On the matter of prerequisites, this book assumes you are competent, if not a Jedi, at basic algebra and arithmetic. Specifically, an understanding of lines, their equations, slope, y-intercepts, x-intercepts, and so on is more or less assumed. I think this is reasonable.”
It was never a loophole.

„Ist der Auftragnehmer eine rechtsfähige Personengesellschaft (z. B. OHG, KG, GmbH & Co. KG, Partnerschaftsgesellschaft, GbR), schließt dies ein abhängiges Beschäftigungsverhältnis zum Auftraggeber im Regelfall ebenfalls aus. Dies gilt jedoch nicht, wenn im Einzelfall die Merkmale einer abhängigen Beschäftigung mit entsprechender Weisungsgebundenheit gegenüber den Merkmalen einer selbständigen Tätigkeit überwiegen.
Nach Auffassung der Spitzenverbände der Sozialversicherung [>>](ISRV:NI:SVBEIEC 2/2004 1) soll dies grundsätzlich auch dann gelten, sofern es sich bei dem Auftragnehmer um eine Ein-Personen-Gesellschaft (z. B. Ein-Personen-GmbH bzw. Ein-Personen-Limited) handelt. Insbesondere bei typischen Beschäftigungsverhältnissen – wie beispielsweise bei den nicht programmgestaltenden Mitarbeitern in der Film- und Fernsehproduktion – kann die Gründung einer Ein-Personen-GmbH oder Ein-Personen-Limited nicht zur Umgehung eines sozialversicherungspflichtigen Beschäftigungsverhältnisses führen. Beurteilt nach den maßgebenden tatsächlichen Verhältnissen sind diese Personen vielmehr weisungsgebunden in die Arbeitsorganisation der Unternehmen eingegliedert. Arbeitnehmer kann – anders als ein Arbeitgeber – ausschließlich eine natürliche Person sein, so dass die Gründung einer Ein-Personen-GmbH oder Ein-Personen-Limited in diesen Fällen sozialversicherungsrechtlich ins Leere geht.“

Not having a late fee doesn’t matter. Most people in the game for rewards have good credit. And you can’t have good credit with missed/late repayments.

Doesn’t matter if you get charged a fee on it or not — not having a late repayment likely matters to you more than the fee you’d be charged for having one.

Then again, judging by FICO scores that are okay for the Apple Card, it’s a entry-level card anyway.
No late fees is nice. Or at least less evil.
I don't believe the article makes this claim. It's not about people actually ignoring the skyscrapers, but rather the low-level layers of the brain tagging them as not worth looking at. This sounds plausible - glassy skyscrapers look a lot like the sky, which isn't very interesting to look at.

Fundamental behavior.

The energy of any photon is the Planck constant multiplied by the frequency. The frequency and energy aren't quantized and can be any value as long as they are proportional.

The energy of an electron in an atom isn't quite so simply expressed but is limited to discrete levels.

This is where emission/absorbsion lines come from or to simplify, color.

Electrons can only accept/emit specific amounts of energy and photons of a specific frequency have an exact energy therefore atoms can only absorb or emit very specific frequencies and all others are ignored.

You can say whatever you want, but I am under no obligation to (a) listen to it or (b) help deliver it to the masses. That is why I agree that providers such as CloudFlare (should) have the ability to refuse to host content such as this.
yeah that would be interesting to try out, thanks for the link :)

I meant that I use tests as a way of poke-prodding things - because Go compiles so fast, and you can run individual tests, it's easy to tool around in test code setting up specific state in code and seeing what happens.

For another perspective of "the study of information in the social world", check out "Variational ecology and the physics of sentient systems" (https://www.sciencedirect.com/science/article/pii/S157106451...). Also based on information theory, released just a few months after op paper.
A common failing of these "for the people" guides is that they fail the most basic UX test: User observation.

When you build a UI, at some point you have to test it on actual people, observing them as they try to use it. Without fail, you'll discover a whole bunch of assumptions you'd made without even realizing it. It's only natural, since you've been working on this project for months and have intimate understanding that you've gained during your time of designs and rewrites and refactorings. But your user doesn't have that history, and you can't remember where common knowledge ends and your assumptions begin anymore. So you do observation tests to expose as many of these as you can.

If you want to make a "for the people" instructional site, it's imperative that you offer an easy feedback mechanism so that people can instantly tell you when something confuses them. Simply relying on success stories exposes you to survivorship bias. Understanding is a two-way street. Design your medium with that in mind, and do LOTS of iterations with real people.

The thing is, that just b/c someone at the tax agency said something, doesn't mean that it is right nor respected when they audit you. A lot of things in this area are not clearly defined and thus open to interpretation leading to all kinds of weird decisions.

The following article (German) is a good read on that:

What kind of free speech are we exactly advocating here? The freedom to spread cheap hate, fake news and bigotry against minorities? I'm sorry but moderating such offenses isn't a limitation to free speech. For the same reason why, if you start shouting nig or monkey to black people in a shopping mall, the police is likely to intervene and take you away - and I don't think that any sane person would argue that they're violating your freedom of speech. Popper taught us that we can't be tolerant towards intolerants, if we really want to protect our tolerant rule of law.

You can still have freedom of speech while implementing moderation to make sure that hate speech, bigotry and fake news don't spread - because if those things spread then they leak into the real world as death. 8chan has been shut down not only because it hosted hate communities, but because it refused to apply any moderation there.

However, the problem is not 8chan alone. It's good to shut down websites where hate speech proliferates without constraints, but a couple of days or weeks later new *chan websites are likely to pop up to replace them, or maybe they'd make a Telegram group. The root problem is Americans. And I'm honestly not sure of how to fix the problem with a whole population that has become so irrational, polarized, ignorant and sensitive to hate speech.

Good attempt, it's good thing to popularize powerfull concepts in programming, which are not as hard as most programmers think they are.

This whole article is terrible:

> derivative in finance is a bet on the rate of change of the value of a stock

No. At least no more than an equity is also based on the change in value of the company. At best it is just a terrible way to describe it. It is a derivative because it derives it's value from the underlying. You can get rid of the "rate" part and it would be more correct.

> The New York Stock Exchange is a company that maintains a database that is a one-stop shop for people who want to trade stocks and other fancy financial instruments.

Don't even know where to begin with how misleading that is.

> that is a reflection of a section of the stock market performing “well”, in the sense of investors making money4 on their stock investments.

Not really. It is the value of the companies going up. I'm sure many are losing money too in both a real sense and a "I shouldn't have have sold" opportunity cost regret.

> Depending on what the Fed’s interest rate is, you could conceivably buy a bond off of somebody for lesser than the principal.

Nope. The feds target overnight rate has very little to do with how bonds outside the very short end, and nothing to do with the long end most people would be buying.

> It’s a zero-sum game, because there are always winners and losers in the stock market.

Not really. While each individual trade is zero sum, the collection of them creates more efficient capital flows and helps they health of the market in a very general sense. Without the traders, the market would dry up and nobody would make any money from it.
To be honest I still can't understand how those big megaprojects got out of the ground with people coordinating by face to face meetings, circulating memos and phone calls

And I do understand those. What I don't understand is growth rate and the slope of a function that is a curve, not a line, therefore not a slope.
What does that mean... don't try to buy individual stocks, just buy the index?

"Just like how taking the derivative of a function gives you the slope, a derivative in finance is a bet on the rate of change of the value of a stock, or a bond, or an index."

No. That is just completely wrong. A derivative is a financial instrument that derives value from other things.

As an aside, the derivatives market is far bigger than the stock market.
Before Germany had the concept of UG we only had GmbH. For a GmbH you need to bank at least 12.500 EUR. Quite a sum if you wanted to start a business. So it was better to create a Limited in the UK and work in Germany. That construct was totally legal, but not really cheap since all the paperwork was for the UK and you ended up paying someone who knew what to do. The German government then created the UG. At grants you liability like the GmbH but you need only 1 EUR to start with.
Not to my knowledge. There are a fair number of documents[1] describing the language to be sure, but it is difficult to divorce K from its implementation(s), so k2, k3, k4, k5 (etc) are all different languages. Your best bet is to download some implementations and try it out. k4 is built-in to kx's q which has a free download[3], just enter a line with a backslash on it to get into k.

Views are just a convenient syntax for memoization. Old versions of the value aren't available.

Adtech pays better than every single thing you're talking about here, except for the instances where you talk about adtech players like Apple. Your whataboutism doesn't change the basic premise, which is that adtech comes with stronger incentives than other fields. Of the much-vaunted FAANG companies, only Netflix doesn't run its own adtech platform (they stuck with good old-fashioned product placement).

What you've done is read too much into an aphorism that is phrased in reference to a well-known poem. It's implied to focus on the information technology sector because it was originally said by a Facebook engineer and quoted in an article about tech bubbles. It's a concise way of expressing disagreement with the priorities of our industry, and nothing more than that.
One thing that you have to in your life is to choose your risk exposure to typical assets: cash, bonds (in particular long term bonds), stocks, real estate, and maybe commodities (like gold, or maybe Bitcoin for the courageous). Sharpe ratio is a good way to measure risk/return.

You have 100% at any given point, where does it go? Not buying anything is going 100% cash. That's why you have to do it - you're always in some exposure.

Then you can always lever up securities, effectively going negative on cash. Example: 105% stocks, 195% long term bonds, -200% cash can be achieved by going 35% UPRO, 65% TLT; only for the brave souls among us that do not fear a 300% leverage. This is roughly how the Bridgewater All-Weather Fund operates (AFAIK you can choose your leverage level there).

Many households are quite levered up by getting a mortgage. A mortgage with downpayment of 20% results in 1/0.2 = 500% leveraged exposure to the real estate market (slowly declining over time as the principal is paid, or if the house appreciates in value).
There is pretty much always someone willing to buy or sell a stock at some price. The best way to think of the exchanges are as a perpetual auction. There is a line of buyers willing to buy shares at all different prices, and similarly there is a line of sellers willing to sell at various prices. Anyone can 'join the line' by entering a limit order at some price.

Buying at market price simply means you immediately buy from the seller offering the lowest price.

It's very rare for an order book to be empty for a particular stock, but you typically do see the bid/ask spread increase as a stock loses popularity.
In the early 90's I used something called QuickMail [1]. It was pretty awesome, especially for its time. You had the ability to do things that SMTP couldn't do, like unsend, see if message was viewed, send 'smart emails' etc. The issue was that it only worked well if other users were on QuickMail. Beyond the other dramas of acquisitions [2], it never really caught on to replace plain old SMTP.

It seems the tides have turned a bit. Now that SMTP email is everywhere, users could reverse the situation. I could say that I will only accept emails which can be parsed by a computer. I (or my provider) could then publish a schema for the types of emails that I'm willing to receive (and how they should be formatted for me). The rest would go into some other folder (ie: spam), that I could look through if I cared enough.

It's using a naive, informal notion of those. If you were to define it formally, well, you'd have the derivative. Which is what he does quite soon after. This is how definitions frequently work in mathematics -- they're meant to take some naive informal notion and formalize it, by coming up with a formal definition that matches how it should work.

So, it's assuming you already have some informal notion of growth rate in your head, like being able to talk about the velocity of an object even when that velocity is not constant. (Imagine the x coordinate is time, and the y coordinate is position (we'll work in one spatial dimension here); then the "growth rate" is velocity.) Then it discusses how to define this formally.
That might be a really good idea. Over the years I've tried multiple website blockers, but I keep turning them off (no judgment please...).

Artificially slowing down those time waster websites instead might do the trick. Not so slow it becomes unusable (or I'll turn it off) , but slow enough that over time I start associating it with a bad experience.

'Speech I don't like' is the kind I can choose to argue with or roll my eyes and ignore. But if people are actively inciting murder, organizing it, and workshopping all aspects of murder technique and how to promote it effectively with the same gusto as any commercial product launch, it's foolish to ignore it.
