reshlo··on The case for letting Malibu burn (1995)
> There wouldn’t be earthquake insurance across much of California if the state didn’t provide it.

That’s fine. If it’s not possible to buy insurance for a particular house at a price that you can afford, don’t live in that house. The state’s other taxpayers shouldn’t be assuming your financial risk.

reshlo··on The Illustrated Guide to a PhD
> It’s not like a bachelor’s because many MD programs start out with or require a BSc

In many countries, the degree you must obtain to qualify as an MD is indeed a bachelor’s degree, the “Bachelor of Medicine, Bachelor of Surgery” (often abbreviated MB ChB or MBBS).

reshlo··on SQL nulls are weird
> If your signup form has an optional field for middle name which I don’t fill, it can absolutely be because I don’t have a middle name.

The fact that some NULLs are indeed undefined doesn’t contradict my point that it would be inaccurate to refer to all NULLs as UNDEFINED.

> It’s undefined and known to be so… And because four value logic was left out, nulls have to fulfil multiple incompatible roles, and ends up being weird.

You know it to be undefined, but if you just leave that field blank on the form, the database still can’t know whether that’s because you don’t have one or because you didn’t provide the one you have, unless there was a field on the form that allowed you to explicitly indicate that you don’t have one.

At the vast majority of companies, if you said to your colleagues “just fork the dependency”, they would look at you like you must be high.
reshlo··on SQL nulls are weird
UNDEFINED would not be accurate. If your signup form has an optional field for a full name which I don’t fill in, I still have a name. Just because a value is not known by your database doesn’t mean it isn’t defined.

E. F. Codd thought about this issue.[0]

> Codd indicated in his 1990 book The Relational Model for Database Management, Version 2 that the single Null mandated by the SQL standard was inadequate, and should be replaced by two separate Null-type markers to indicate why data is missing. In Codd's book, these two Null-type markers are referred to as 'A-Values' and 'I-Values', representing 'Missing But Applicable' and 'Missing But Inapplicable', respectively. Codd's recommendation would have required SQL's logic system be expanded to accommodate a four-valued logic system. Because of this additional complexity, the idea of multiple Nulls with different definitions has not gained widespread acceptance in the database practitioners' domain. It remains an active field of research though, with numerous papers still being published.

reshlo··on In my life, I've witnessed three elite salespeople at work
Especially considering that even the unreliable narrator himself admits he was one of the first ones to be fired - why would you fire the best employee first if it wasn’t for cause?
reshlo··on The Future of Htmx
Because your potential dependencies will require 5.x as a peer dependency, so you have to use 5.x. Because your current dependencies will fix bugs or introduce features that you need in versions that upgrade their peer dependency to 5.x, so you have to use 5.x. Because the package itself will fix certain bugs that exist in 3.x but will only fix them in 5.x, so you have to use 5.x.

The point is he did not read the scripts verbatim as you claimed.

The article states that he was fired because he did not read the script he was required to read.

> In general I think it's very easy to _not understand_ people i.e. "how could you". The interesting part for me is when I do understand: "oh this is how".

“How could you” is a rhetorical question to which the asker already knows the answer they would be given, which is almost invariably “because I lack empathy”.

reshlo··on In my life, I've witnessed three elite salespeople at work
Isn’t the point being made in that passage that the better you are at sales, the more you treat your loved ones as customers you can transactionally extract value from by leveraging your sales tactics, rather than just… loving them? I don’t see how this connects to your comment on chefs and F1 drivers needing both grit and talent.

How did you just argue both that companies need backup plans to keep wages low in a supply shortage and also that immigration, which solves supply shortages, does not keep wages low; and not see that those claims are contradictory?
reshlo··on Postgres UUIDv7 and per-back end monotonicity
> Normally, time-based UUIDs from this document will be monotonic due to an embedded timestamp; however, implementations can guarantee additional monotonicity via the concepts covered in this section.

“Normally, I am at home because I do not have a reason to go out; however, sometimes I am at home because I am sleeping.”

Notice how this statement does not actually mean that I am always at home.

reshlo··on EU law mandating universal chargers for devices comes into force
Probably a combination of the devices being old enough and the battery not being large enough that a lot of people would not find 80% of the already-degraded capacity of their device reasonable, and not wanting to have to explain to customers why their friend’s phone allows it and theirs doesn’t if they both have the same model.

reshlo··on Earth's subsurface may hold up to 5.6 × 10⁶ million metric tons of hydrogen
In this case it’s probably “this is a silly question”.
reshlo··on Earth's subsurface may hold up to 5.6 × 10⁶ million metric tons of hydrogen
> Hydrogen escape on Earth occurs at ~500 km altitude at the exobase (the lower border of the exosphere) where gases are collisionless. Hydrogen atoms at the exobase exceeding the escape velocity escape to space without colliding into another gas particle.

> For a hydrogen atom to escape from the exobase, it must first travel upward through the atmosphere from the troposphere. Near ground level, hydrogen in the form of H2O, H2, and CH4 travels upward in the homosphere through turbulent mixing, which dominates up to the homopause. At about 17 km altitude, the cold tropopause (known as the "cold trap") freezes out most of the H2O vapor that travels through it, preventing the upward mixing of some hydrogen. In the upper homosphere, hydrogen bearing molecules are split by ultraviolet photons leaving only H and H2 behind. The H and H2 diffuse upward through the heterosphere to the exobase where they escape the atmosphere by Jeans thermal escape and/or a number of suprathermal mechanisms.

reshlo··on Can AI do maths yet? Thoughts from a mathematician
> That's the equivalent to what we are asking the model to do.

Why?

What does it mean to give a model a calculator?

What do you mean “let it show its working”? If I ask an LLM to do a calculation, I never said it can’t express the answer to me in long-form text or with intermediate steps.

If I ask a human to do a calculation that they can’t reliably do in their head, they are intelligent enough to know that they should use a pen and paper without needing my preemptive permission.

reshlo··on The number pi has an evil twin
> A complete stranger who has nothing whatsoever to do with you, who has never tried to do anything for you, nor has been expected to, has never disappointed you. They've also never failed to disappoint you, because they have not failed in any regard whatsoever.

Nobody who uses the phrase ever means it in this way. The point of using the statement is to convey that you are familiar with the person’s history.

As another commenter has already pointed out, “has never failed to disappoint” is not the same statement as “never fails to disappoint”. The habitual present can’t refer to empty sets, as it is only used to refer to repeated actions.

Not in a way that matters here.

As alluded to by the source in my last comment, formaldehyde is produced in a variety of ways inside the human body, including literally inside our cells, in the mitochondria. It is also used as an input in other biological processes. These processes collectively result in formaldehyde being continually present in the bloodstream in quantities more than a thousand times higher than the residual amount potentially present in a single vaccine dose. Therefore, one vaccine dose would not have a measurable effect on the amount of formaldehyde already in the blood, let alone inside cells and elsewhere. The body is very good at maintaining formaldehyde homeostasis. If it were not, we would be poisoned by our own cellular processes and typical diets.

> The continuous generation and degradation of formaldehyde in the body serve to maintain the homeostasis of formaldehyde metabolism. A common mechanism of formaldehyde generation is located in the mitochondria by the action of serine hydroxymethyltransferase 1 and 2…

> The main source of exogenous formaldehyde in healthy individuals may be through various fruits, vegetables, meat and alcoholic beverages…

Regarding aluminium, the link I cited in my previous comment addresses this.

> Once aluminum ends up in the blood, its source does not matter, meaning that our body processes it the same way regardless of how it arrived in the blood…

> Once the aluminum associates with one of these new partners, it is carried to the kidneys, where about half of it is removed from the body within 24 hours. Half of the remainder is removed by the next day, etc…

> Although the relative quantity of aluminum introduced on a vaccination day may be significantly greater than that introduced by food on that day, over time, we are exposed to more aluminum from food than from vaccines because the exposure from food occurs daily. If you consider that half of the aluminum in the blood is removed from the body every 24 hours, you will realize that each day additional aluminum is introduced through food. As such, over time, most of the aluminum in the blood could be traced back to that source…

Two minutes of research would have saved you the embarrassment of making that comment.

> Formaldehyde is essential in human metabolism and is required for the synthesis of DNA and amino acids (the building blocks of protein). Therefore, all humans have detectable quantities of natural formaldehyde in their circulation (about 2.5 ug of formaldehyde per ml of blood). Assuming an average weight of a 2-month-old of 5 kg and an average blood volume of 85 ml per kg, the total quantity of formaldehyde found in an infant's circulation would be about 1.1 mg, a value about 1,500 times more than the amount an infant would be exposed to in any individual vaccine.

https://www.chop.edu/vaccine-education-center/vaccine-safety...

> While infants receive about 4.4 milligrams* of aluminum in the first six months of life from vaccines, they receive more than that in their diet. Breast-fed infants ingest about 7 milligrams, formula-fed infants ingest about 38 milligrams, and infants who are fed soy formula ingest almost 117 milligrams of aluminum during the first six months of life.

> People take meth and coke and go on se, gambling binges. Something that moderates and manages dopamine in a way that breaks the hold gambling and social media has on people's brains would be very different.

Simplifying a lot here, but people with ADHD are statistically more likely to exhibit addictive behaviours because the addiction provides dopamine that their brain otherwise has trouble getting. Treatment with prescribed CNS stimulants is very effective at preventing those behaviours because the brain no longer has to engage in the addictive behaviours to obtain sufficient dopamine.

Here’s one study where patients reported significantly lower rates of alcohol and drug use over at least a one year period.
