alexpetralia··on Getting a Cease and Desist from Waffle House
The issue is moreso that they exclusively control their brand, and by letting someone else - who doesn't work for them and need not listen to them - control part of that, they are indirectly loosening control of their brand and narrative. They probably do not want the additional headache of buying this product, onboarding it, managing it, etc. The easiest but unfortunate solution here, to limit risk and liability, is to shut it down.

This is exactly what "small government" and "big business" means
alexpetralia··on 75K federal workers accepted 'deferred resignation' offer
I think that, on the contrary, government contracts will increase. There will be increased privatization of government services. These services cannot cease, but they will cease to be performed by the government. I imagine government contractors like Palantir will actually do quite well. A smaller government is good for business due to privatization, but perhaps more often bad for people subject to those businesses with less government oversight.
alexpetralia··on Does X cause Y? An in-depth evidence review (2021)
I have reflected on a good definition of causality and would be curious if anyone has thoughts or critiques of it. I am repasting part of my essay below. (https://alexpetralia.com/2023/02/25/statistics-only-gives-co...)

--

Can we nevertheless extract causality from correlation?

I would argue that, theoretically, we cannot. Practically speaking, however, we frequently settle for “very, very convincing correlations” as indicative of causation. A correlation may be persuasively described as causation if three conditions are met:

Completeness: The association itself (R²) is 100%. When we observe X, we always observe Y.

No bias: The association between X and Y is not affected by a third, omitted variable, Z.

Temporality: X temporally precedes Y.

alexpetralia··on Is Atlas Shrugged the New Vibe?
I find this nicely captures the difference between "rationality" and "reasonableness". A system can be rational but rest on unreasonable assumptions; a system may not be entirely rational but at least can have reasonable assumptions.

Aha, Chekhov's coffee as well it seems!
alexpetralia··on Technical debt vs. technical assets: What's the difference?
Technical debt is a former technical asset without its owner.

On the technical side, you will interface with our data stack of Airbyte, Snowflake, dbt, Prefect, Python, Tableau and SageMaker (among others). On the business side, you will work with our sales, marketing, operations, product and finance teams to drive top-line growth metrics (e.g. sales, usage, conversion).

Bingo.
alexpetralia··on Ask HN: Is it wrong to use my personal laptop for work?
If you have a doubt about the right thing to do insofar as the company is concerned, you should ask the company. The fact that you asked HN first suggests that you already know the answer.
alexpetralia··on Reflections on Palantir
"End-to-end data engineering and analytics" is quite a bold claim from a single service provider.

Here is the link for anyone interested: https://www.palantir.com/platforms/foundry/ and a YouTube explainer: https://www.youtube.com/watch?v=ZGGRCTTjLfQ

Given you've used it, just how self-service is it? To me this seems like such a large claim that - if it's doable - I'm surprised there are not more competitors in the "vertically integrated data providers" space.

I ordered mine over eBay. They only ship from resellers in Japan.
alexpetralia··on ReMarkable Paper Pro
1. It may (as I do know it has OCR) but I am not sure for handwritten notes

2. Yes

3. I download all PDFs onto my phone, then NFC "tap" them onto my device. Similar vice versa

alexpetralia··on ReMarkable Paper Pro
I use it "off and on" (say 1-2 hours each day) for several days.. I probably charge it once every 3 to 4 days (and by then maybe it's 30-40%)? I haven't noticed a battery issue at all. My intuition is it lasts a week with normal usage. I always make sure to keep Wifi/NFC off of course (as it is not an Internet device).
alexpetralia··on ReMarkable Paper Pro
I use the Fujitsu Quaderno A4 as my daily reader and notetaker (PDFs only).. it is absolutely fantastic. Simple but extremely thoughtful design. Extraordinarily light, durable, long battery. "It just works".

alexpetralia··on I mapped almost every USA traffic death in the 21st century
Don't just think about the deaths.

Think about all the injuries too. All the environmental damage. All the people that don't hang on the street because of the fumes and noise and danger. All the road rage and cortisol that boils within otherwise sane people the moment you put them behind a wheel and into some traffic. All the sedentarism and obesity from people opting to drive 2 minutes rather than walk 10. All the forgone housing for parking stadiums.

I am all for convenience, but the costs are noticeable in more ways than one.

alexpetralia··on The Death of NYC Congestion Pricing
Downtown areas in Tokyo have virtually zero public parking spaces.

They made it very, very inconvenient to drive.

alexpetralia··on NYC banned Airbnbs to make housing cheaper, but only made hotels more expensive
But actually, it does, because more housing supply (even on the high end) means fewer higher earners are forced to bid up generic housing for the masses.

On the other hand, refusing to build any housing at all (for whatever the reason is: too unaffordable, too gentrified, too out-of-place) means those high earners will live in generic housing for the masses, and those places will be expensive.
