Site QC: I clicked on the Twitter link in the footer. It references podbabble1, an account that doesn't exist. https://twitter.com/podbabble exists though.
getpost··on It's 2022, phones should be built to last five years or more
iphones (and ipads) do last 5 years or more, both hardware and software support; it's a key differentiator from the android ecosystem. A more easily replaced battery would be nice.

getpost··on Mastering Metacognition: The What, Why, and How
Metacognition or “mentalization”[0,1] is a promising approach to mental health, on the theory that mental health difficulties reflect a metacognitive deficit.

getpost··on What's in a good error message?
“Unexpected friend” was one of my favorites in C++. It seemed fortuitous; it’s good to have friends, right? (Usually the actual error was a missing semicolon.)
getpost··on My out-of-body experience in a sensory deprivation tank
I found it very relaxing, which I attribute mainly to absorption of magnesium. I usually had a “good” meditation session, but never any experience of non-ordinary consciousness. I stopped going for sessions after contracting a serious case of bacterial dermatitis.

>the key take away is that insulin is produced in response to excess carbohydrates,

Citation? My experience is consistent with yours. However, my understanding is that insulin is mainly a signal to cells to take on nutrients, and it is not exclusively a response to carbohydrates, much less "excess carbohydrates." Certain amino acids provoke an insulin response, for example. https://pubmed.ncbi.nlm.nih.gov/2660133/

getpost··on On YouTube’s recommendation system
I always watch logged-out. (Occasionally on iOS I will be unknowingly logged-in, not sure how that happens. I log out if I notice I am logged-in.) YouTube seems to maintain an identity for me, and auto-constructs playlists using past items viewed. Recommendations appear to relate to past viewing.

I’m uncertain on how cookies are maintained. Are these Safari cookies behind the scenes?

My point is, contrary to GP’s claim, there is some mechanism for viewing history even if it is turned off.

getpost··on Robert Sapolsky on Depression (2009)
"Chemical imbalance" is not only a marketing phrase. Lots of people are willing to receive treatment for a "chemical imbalance," but aren't willing to engage in therapy, or admit they're depressed. This was very common in the last couple decades prior to the turn of the century, when mental illness was much more stigmatized than it is now.
getpost··on Ask HN: Whats your ideal PhD workflow
Not what you're asking, but my ideal phd workflow is to complete an open research problem as a homework assignment, then turn it in as a thesis.

"In 1939, a misunderstanding brought about surprising results. Near the beginning of a class, Professor Neyman wrote two problems on the blackboard. Dantzig arrived late and assumed that they were a homework assignment. According to Dantzig, they "seemed to be a little harder than usual", but a few days later he handed in completed solutions for both problems, still believing that they were an assignment that was overdue.[4][6] Six weeks later, an excited Neyman eagerly told him that the "homework" problems he had solved were two of the most famous unsolved problems in statistics.[2][4] He had prepared one of Dantzig's solutions for publication in a mathematical journal.[7] This story began to spread and was used as a motivational lesson demonstrating the power of positive thinking. Over time, Dantzig's name was removed, and facts were altered, but the basic story persisted in the form of an urban legend and as an introductory scene in the movie Good Will Hunting.[6]

Dantzig recalled in a 1986 interview in the College Mathematics Journal, "A year later, when I began to worry about a thesis topic, Neyman just shrugged and told me to wrap the two problems in a binder and he would accept them as my thesis."[8]"

getpost··on I Was Paralyzed by Severe Depression. Then Came Ketamine
If by "anecdotal," you mean personal stories, not medical studies, that's no longer true. There are many studies comparing psychedelics with conventional treatments for depression and PTSD (eg below). Psychedelics have been repeatedly shown to work faster, 'better,' and provide longer-lasting relief than conventional treatments. Indeed, some studies selected treatment-resistant cases, so results apply to cases in which mainstream treatments have already failed.

Additional monitoring and analysis are always needed, as with any medical treatment. Depression can be a fatal illness, so avoiding effective treatment until the field is more "mature" may cost lives.

getpost··on The Expanse UI Design
I was inspired by the transparent 3D displays. It looked like exactly what I'd want.

I can't think which episodes, but there's are a couple scenes where detective Miller is looking at his phone in 2D mode, and he says, "Go 3D." In one scene, he interacts with the 3D projection, reorienting it. In another scene, invoking the 3D display makes it possible for everyone in the room to discuss the projection.

I'd love to know how these effects were done. And, when can I have one of those phones?

Apparently the insider moniker for the show is, “The Expense.”

getpost··on Rich people do have trouble understanding what it's like to be poor
In practice, a lot of bad choices aren't truly volitional; they are mainly the result of conditioning. Repeated bad choices reflect a reduced capacity to learn, which is a kind of disability.

It's annoying and costly that so many people make these bad choices, but I think we still have the obligation to care for each other. I expect to make at least some bad choices and I may need help.

But usually, nobody can help you as much as you can help yourself, so it's a good idea to arrange things so that people can increase their own resourcefulness and help themselves.

Be grateful for how lucky you are.

I agree on the practical level, which is pertinent here.

It is possible to experience non-dual consciousness in high concentration states. [EDIT: For many, this experience is a milestone in psychospiritual development, which undermines the habit of dichotomous thinking.] Awareness and perception aren’t the same thing. Way, way off the subject, but your main point stands, be mindful of priors.

getpost··on Fierce Nerds
Clarity is about seeing how things are, not how you've chosen to divide things up.

(I added this as an edit to my other reply, but it seems the edit is lost.)

getpost··on Fierce Nerds
This is a deep topic worthy of an essay, the kind of essay pg might write! The concise reply is, when you catch yourself in dichotomous thinking, you should assume you have misunderstood or oversimplified.

Sometimes you have to go with your misunderstanding or oversimplification to make a decision or to make progress, but keep in mind you are doing so based on beliefs which are unlikely to correspond to reality.

It's striking that so many mental health difficulties are characterized by dichotomous thinking. [1]

Rationality itself can be profitably critiqued at the meta-level.[2] So, don't be an asshole, unless you need to be. Do you see the world as consisting of assholes and non-assholes? How does that feel? What are the advantages of that view? What are the disadvantages? Is considering that question worth your time?

Since pg's essay is of a psychoanalytic nature, I'll reply in a psychoanalytic frame, for the sake of conversation, not criticism. [Protip: never psychoanalyze anyone! This likely applies even to psychoanalysts.]

During the last year or two pg has written more than a few essays and tweets which appear to be of a defensive nature. People like him contribute more than other people, it's alright to to be fierce, can't speak the "truth," etc.

Whenever there is dichotomous thinking, cognition has moved away from clarity. If it were me, I'd be asking myself, What is being defended? (This kind of question can be a multi-decade inquiry.)

Although most of us are easily baited into self-justification or self-promotion, I think going down that path it is ultimately a distraction from doing real work and knowing who you are.

Two obscure features of the Lisa that weren't retained on the Mac (IIRC):

Pixels on the Lisa were not square. Tall rectangular pixels made for better font rendering.

The Lisa had virtual memory? Not sure about that, but there was a neat feature that trapped stack overflows. The OS could expand the stack with the overflow trap was triggered.
