jprete··on Hey, wait – is employee performance Gaussian distributed?
The GP is saying that IQ tests are deliberately calibrated and normalized to produce a Gaussian output, and that the input is not necessarily a Gaussian distribution of any particular quantity.

This doesn't say anything in particular about whether it's useful, just that people should be careful interpreting the values directly.

jprete··on Copyright-Free Images Made Easy for Creators
So...copyright theft then?
jprete··on When did estimates turn into deadlines?
That's a hyperbolic misstatement of the situation on the ground. Poor people use free emergency rooms as primary care instead of paying for primary care physicians. That's a cost disaster no matter what you think should be done about health care. We'd be much better off with actually free primary care for the poor, and it would at least make sense to prevent the emergency room misuse since it's so wasteful. But it's politically untenable in the US to fix a broken system in any direction people don't like, even when it's Pareto optimal.
jprete··on I was banned from the hCaptcha accessibility account for not being blind (2023)
The endorsement and verification would need to be continuous, or else the anonymous users will sell their accounts for the value of the accrued positive reputation. I.e. what people already do with Reddit accounts that accrue a lot of karma.
jprete··on Good Software Development Habits
Not the GP but I think a foundational skill is naming things. If you can't give a simple name to a function/class/etc., it's probably not well-defined. It should be adjusted to make it easier to name, usually by moving responsibilities out of (or into) the code structure until it represents one concept that you can clearly state as a name.
jprete··on Emit-C: A time travelling programming language
Touche.
jprete··on Emit-C: A time travelling programming language
I take it you've never heard of Poe's Law?
jprete··on A neurology ICU nurse on AI in hospitals
Efficiency and lowered costs are not universally good. They strongly favor easily-measured values over hard-to-measure values, which in practice means preferring mechanisms to people.
jprete··on High Levels of Banned PFAS Detected in Hershey's Packaging
The first thing I saw on the page was a phone-screen-filling disclaimer that everything they said was opinion. I didn't read any further.
jprete··on The egg or the chicken? An ancient unicellular says egg
I guess it depends on whether the crucial mutation that flipped the organism from "non-chicken" to "chicken" happened before or after fertilization!

Or alternatively we can say that the germ line went from 49% chicken to 50% chicken to 51% chicken? Biology is really a continuous state space anyway and trying to push things into categories too hard will break them.

jprete··on The decline of the working musician
The GP was clearly talking about dancing as a social activity. TikTok dancing isn't social, it's a performance for an invisible audience.
jprete··on The Therapist in the Machine
There are many benefits to a therapist. Understanding a problem is not the same as solving it, and many problems are not cognitive dissonances.
jprete··on Perplexity CEO offers to replace striking NYT staff with AI
If Perplexity can substitute for the NYT's staff for an essential news story, then it can substitute for their staff for almost all stories. However, I don't think that's even the attack Srinivas was going for - he's indirectly claiming that the NYT's subscribers don't need the NYT for the source of its prestige and power - its news reporting.
jprete··on Perplexity CEO offers AI company's services to replace striking NYT staff
There's another thread at https://news.ycombinator.com/item?id=42044956 with 13 comments.
jprete··on Ask HN: How can tech help with mental health?
Videochat therapy is OK as a stopgap, and it saves travel time, but it puts a barrier between the person and the therapist. If the patient doesn't need that barrier to go to therapy in the first place, then that distance may make the therapy less effective.
jprete··on Breaking the image: a 12th-century Ai Weiwei?
I had the same question! For other readers, Ai Weiwei is an artist: https://en.m.wikipedia.org/wiki/Ai_Weiwei
jprete··on Sketchy financials send Supermicro auditors running for the hills
Was the Fool article stealth-updated? It's not particularly positive at the moment.
jprete··on Wikipedia article blocked worldwide by Delhi high court
If the court order specifies that it be taken down worldwide, and the court order isn't definitely illegal according to Indian law, and the Wikimedia Foundation has operations in India that they want to preserve, they may not have a choice.
jprete··on Wikipedia article blocked worldwide by Delhi high court
This article might be more informative although I can't say how accurate it is: https://www.thehindu.com/news/national/wikipedia-suspends-ac...
jprete··on Jeff Bezos killed Washington Post endorsement of Kamala Harris
It's relevant on the margins. WaPo not endorsing Harris would be a very negative signal about Harris for fence-sitters and lukewarm voters - this is the paper that hated Trump so much they changed their motto to the apocalyptic "Democracy Dies in Darkness"!
jprete··on Dijkstra's algorithm prove as universally optimal way to find graph's best route
A* is faster in practice if the heuristics used by the specific implementation are accurate and if the graph is "general" for the problem space. I'm being very loose with the word "general" but essentially it should have typical structure for the problem space it represents.

There's almost certainly a paper somewhere proving that A* with a given heuristic can always be made O(large) by choosing the right adversarial inputs.

jprete··on Everything I built with Claude Artifacts this week
That's effectively an answer of "no".
jprete··on Computer use, a new Claude 3.5 Sonnet, and Claude 3.5 Haiku
Top comment at the time I looked:

"There seems to be a ton of confusion about the purpose of these ads. These are recruitment ads, not product ads, hence why "no drama" is the driving message. I'm sure these were all taken at or around a tech conference."

jprete··on Woman, 82, still rides same bike she was given at 13
We've been in the mid manufacturing era for quite a while, when every part is engineered to fail the day after the warranty expires. Maybe the idea of a bicycle that can last seven decades is interesting to people.
jprete··on Microsoft and OpenAI's close partnership shows signs of fraying
It's generally bad writing to use the same phrase structure over and over and over again. It either bores or distracts the reader for no real advantage. Unless they really could not find an adjective clause other than "familiar with" for sixteen separate instances of the concept.
jprete··on Impact of early life adversity on reward processing in young adults (2014)
I think that's the whole house, not just bedrooms.
jprete··on Adobe's new image rotation tool is one of the most impressive AI tools seen
This probably isn't backed by an LLM but instead some kind of geometric shape model.
jprete··on Chinese researchers break RSA encryption with a quantum computer
At least they're publishing it!
jprete··on OpenAI Is a Bad Business
Businesses are interested in AI so they can fire employees and do the same amount of work with much cheaper AI instead. The whole point is to scrimp.
jprete··on Life expectancy rise in rich countries slows down: took 30 years to prove
Ozempic seems to have a large number of positive effects for virtually everyone. It's a little premature to think everyone will be on it "soon" and there are plenty of people who won't take something even if it's universally beneficial.
