kyshoc··on Seizing the Middle: Chess Strategy in Business
James Carse has a theory[0] about this: “There are at least two kinds of games. One could be called finite, the other infinite. A finite game is played for the purpose of winning, an infinite game for the purpose of continuing the play.”

kyshoc··on Seizing the Middle: Chess Strategy in Business
While I appreciate the “middle” metaphor, I think it’s unwise to generalize business (and real life situations, more broadly) as a chess game — life doesn’t often come with symmetric information and zero-sum stakes. Annie Duke says it better than I can, in her book[0]:

> “Chess is not a game [in a game theory sense]. Chess is a well-defined form of computation. You may not be able to work out the answers, but in theory there must be a solution, a right procedure in any position […] If you lose at a game of chess, it must be because there were better moves that you didn’t make or didn’t see.”

> “The decisions we make in our lives—in business, saving and spending, health and lifestyle choices, raising our children, and relationships—easily fit von Neumann’s definition of ‘real games.’ They involve uncertainty, risk, and occasional deception […] Trouble follows when we treat life decisions as if they were chess decisions.”

kyshoc··on 20 months, 2K hours, 200K € lost. A story about resilience and sunk cost fallacy
To split this hair a bit, I think “code quality” has two definitions:

1. the degree to which the code can be trusted to operate correctly and in a fault-tolerant way (i.e. “yeah that API endpoint will give you a 5xx about 2% of the time, sorry about that, just retry!”)

2. the degree to which the code optimally models the problem it’s solving, as well as how flexible it is as priors/needs change in the future and whether optimal languages/frameworks/patterns are used to solve the problem expressively.

The former has obvious customer implications — if your webapp craps out every ~20min of usage, or your API silently drops data when it can’t persist something to a data store, that’s bad, you will lose customers (and you deserve to!). Conversely, lacking in the latter could slow you down as you iterate, but you’re just as likely to not need to touch that code for a while if you’re off building new views/features/what-have-you.

I think the “don’t worry about code quality” folks are generally trying to beat it into technical founders/builders’ heads that the thing they’re building is ultimately being judged as a product, not as an engineering project... but that doesn’t mean that reliability and performance aren’t part of what may make your product valuable.

> why aren't most messaging apps peer to peer [...] it's literally the point of messages: sending from one person to another.

Messaging apps are more like postal services — "please deliver this message to $person" — you're describing driving across town to drop something in a mailbox directly. A peer-to-peer messaging system wouldn't have many benefits over an E2E-encrypted one (in a centralized E2E-encrypted service you already enjoy technical guarantees that the courier can't peek inside the metaphorical envelope), but would have several usability drawbacks that would drive away casual users, which the sibling comments mention.

Driving away casual users has its own problems: you might drive them away to insecure services ("ah fuck it, this thing doesn't work, I'll just DM them on Twitter"), and the lack of casual users will make your remaining users stand out in traffic analysis (e.g. state agency says "hmm, askxnakjsn is using SuperEncryptoP2PMessenger, better go make sure they aren't a dissident").

kyshoc··on Ask HN: What is going on with the US stock market?
I don’t know much more than you on this, but I’ve seen this explained as such: inflation requires the injected money to actually be circulated in the economy in order to dilute the value of the currency. of the money distributed to companies and individuals during the pandemic, how much of it went to everybody’s “rainy day funds” and war chests? Most folks I know that are on unemployment right now have touched <20% of their funds, and Americans just hit a record savings rate[1] last month. Schwab has an article[2] that explains the monetary effects of this better than I.

that's a wild way to run meetings — in my current organization, finishing a meeting ahead of schedule (when appropriate) is celebrated as "giving time back".

kyshoc··on DEA agents conduct surprise searches of Amtrak passengers
It goes deeper than anecdotal "I wish my client hadn't said anything", there are concrete reasons for this advice.

For example, according to rules of evidence, any exculpatory statements you make to police are hearsay and therefore cannot be mentioned in a trial. The police _can_, however, try to use that information against you and then use information derived from your original statement at trial.

There's a pretty popular lecture[0] on this. It covers a lot of edge cases and common arguments against "don't talk to the police".

> In a truly free market, companies aren't supposed to do anything [...] In a regulated market though...

Free market !== unregulated market.

In order for an unregulated market to be a free market, perfect competition is required[0], otherwise you get market failure.

In the real world, we use laws to discourage behavior that leads to market failure.

kyshoc··on 7.1 magnitude earthquake strikes Southern California
> why is a strong table to be looked for inside, to get underneath it?

Modern buildings don't usually completely collapse ("pancake"), and being under a sturdy table can absorb the weight of partial collapse: as an example, an interior wall collapsing onto you. See [0].

> I would imagine basements are bad to be in, is that so?

All I know about this is that having a (code-compliant) basement makes the entire house more resilient, but I couldn't find anything about being _in_ the basement during an EQ being good or bad. Know that basements in low-density structures are quite scarce[1] in Southern California, though -- I've lived in LA for four years and don't remember ever being in one, except in large apartment buildings.

Don't try to get out of a basement if you're in one when an EQ hits. Most injuries are a result of people breaking their ankles and legs trying to move while the ground is shaking.

> I would imagine upstairs is a bad place to be too, right?

It's a tradeoff. In the event of a structure collapse, you have further to fall but less structure to fall on top of you.

> does the ground really split underneath your feet?

Yes, if you're straddling the fault line and standing near the epicenter. (You won't be doing that).

There has never been a confirmed case of someone falling into an "earthquake chasm", but it might be something to worry about if you're a cow grazing in a Bay Area field[2].

Take a look at this study[3] of the 74 deaths caused by the '94 Northridge EQ. It's the best data we can use to project what would happen if a major EQ hit LA today.

kyshoc··on U.S. Life Expectancy Drops for Third Year in a Row (2018)
You're imagining this to be more friendly than it is -- "can't pay for emergency medical care" in the US is a euphemism for "got a bill from the hospital, couldn't pay it, so the hospital sold the debt to a collections agency and wrote the account off as a loss", not a reference to a forgiveness program.

Since the hospital takes a loss in those cases (and has to, since they have to treat everyone), everyone else's cost of care goes up to subsidize the loss.
