mr_overalls··on Extremely Low Frequencies
Sometimes the brain’s auditory cortex can 'misfire' and create sounds or voices that feel 100% real, even when there's no outside signal. It’s actually a documented medical phenomenon.

Comparing this to Dachau suggests you’re feeling a massive amount of psychological pressure. Usually, when the mind is under extreme, prolonged stress, it can start to externalize internal thoughts as voices or 'beamed' messages. It might be worth talking to a professional about the distress this is causing you—they might have ways to help mute those signals.

mr_overalls··on Inflatable Space Stations
If we're talking about objects in the asteroid belt, the internal consistency varies wildly. Most smaller objects are indeed rubble piles: boulders, pebbles, and sand-like grains, down to dust. As you'd expect, they're very weak structurally. Notably, the OSIRIS-REx probe was nearly swallowed by its loose material during the sample collection on Bennu.

Some of the other large, iron-rich asteroids like Ceres, Vesta, Pallas, and Interamnia are more like protoplanets than rubble piles.

Besides the concern for structural integrity/stability, they also have reasonable amounts of water ice, volatiles, metals, ad other resources needed to supply an outpost.

mr_overalls··on A NASA satellite that scientists and farmers rely on may be destroyed on purpose
It's just astounding to see a scientific superpower destroy itself intentionally.
mr_overalls··on Mystery 'Disease X' outbreak widens as WHO sends rapid response team to DR Congo
Nah, the businessman was probably in a more urban area, and he likely came into contact with a person (or contaminated item) who had recently been in the extremely rural area of outbreak.
mr_overalls··on Uranus should be NASA’s top planetary target – report
Aren't multi-stage rockets essentially "lifting fuel into orbit"?
mr_overalls··on You cannot police misinformation in a fair, reproducible, and representative way
Russia has has something 130,000 troops positioned just outside Ukraine's borders and in Belarus. They have tanks, missile systems, amphibious landing ships, medical units, established supply lines, etc.

They actually invaded Ukraine in 2014 and took Crimea.

I mean, the possibility of an invasion is not exactly far-fetched.

mr_overalls··on Microsoft posts its own teardown and repair video for the Surface Laptop SE
This. I live in Madison, Wisconsin (aka, the "Berkeley of the Midwest") where tattoos and facial piercings are absolutely the norm - even my kids' daycare teachers openly sport them.

When I return to my small Mississippi hometown, only "rough" people openly display tattoos, and generally only a small minority of men are not clean-shaven with short haircuts. Male jewelry is minimal, things like facial piercings are heavily frowned upon, etc.

Regional norms can be very different.

mr_overalls··on California Considers Doubling Its Taxes
The United States is still the only country in the developed world without a system of universal healthcare.

Breathlessly comparing the USSR's economic policies with the raising of taxes to cover such a fundamental service betrays a staggering ignorance of economics and history.

mr_overalls··on Chemical emitted by babies could make men more docile, women more aggressive
Also TMI (and let's be honest: mega-creepy) I can tell when women are menstruating with about 90%+ accuracy if we share small-ish indoor space for a few minutes. (As confirmed by female family members.)

It's not so much an obvious smell as a perceived "sharpness" that feels related to the sense-modality of smell, but is not exactly equivalent to it. I wonder sometimes if it's a pheromone-based phenomenon.

mr_overalls··on Ivermectin: Much More Than You Wanted to Know
Speaking of "the public" as a single entity is about as useful as approximating a curve with a straight line - i.e. unless it's the most trivial case, it's oversimplified to the point of being doomed to failure.

The public is comprised of people with vast differences in cognitive ability, education, and scientific training. Most members of the public, even in highly educated countries, are easily fooled by a wide variety of logical fallacies, emotional manipulation, and statistical misdirection.

> they are definitely black hats

Both intelligence agencies and cyber-criminals can be considered threats, but they are quite different. Intel agencies would present a serious threat to confidentiality, but are very unlikely to threaten the integrity & availability of business systems.

mr_overalls··on Richard “Lowtax” Kyanka, creator of Somethingawful, has died
I would not so quick to judge the circumstances surround their divorce. There are quite serious allegations of physical and financial abuse lasting for years.

mr_overalls··on Plans to shift aviation from magnetic navigation to true navigation
Not saying you're wrong, but. . . who actually knows what actual top-grade INS is doing these days? Those kinds of capabilities would probably be Top Secret or SCI.
mr_overalls··on How my ivermectin research led to Twitter death threats
> the tribe that reacts to any criticism of public health experts with hostility and threats of violence. . .

The thing with playing syntactic games like this is that your altered sentence. . . isn't actually true. The two sides in relation to COVID research and official guidelines actually do behave differently.

mr_overalls··on We Are Beast Machines
7) A purely phenomenological viewpoint (such as the one held by some schools of Mahayana Buddhism) would claim that the only reality is one's own mind. The steel block along with all other aspects of perceived reality, are akin to a magical illusion or dream.
mr_overalls··on Army delays $22B augmented reality goggle program
> The last time the battlefield was insanely lethal people just dig trenches to even survive the day.

Trench warfare proliferated when a revolution in firepower was unmatched by similar advances in mobility.

Most likely, ongoing advances in stealth, armor, area denial, anti-drone tech, etc. will preclude its reappearance on the battlefield.

mr_overalls··on Why Japan Looks the Way It Does: Zoning [video]
Okay, I'll admit I had the same reflexive skepticism to your initial comment as the person you're replying to. . . and your very well-reasoned, detailed response is emblematic of the reasons I keep coming back to HN.
mr_overalls··on Why NoSQL
At some point when designing a data store, decisions must be made with regards to memory layouts, integrity, transaction guarantees, ease of replication, etc. These choices typically involve reliability vs performance tradeoffs for various use cases.

I mean, you _can_ store graph data in a relational database, but its' not typically easy to insert or query, there are serious performance penalties, etc. Purpose-built data structures will always out-perform generic ones.

mr_overalls··on Why NoSQL
> radically different approaches

Exactly. Relational databases are fantastic general tools, but various use cases can make more specialized data stores the best choice for a particular job.

Document stores, key-value stores, column-oriented databases, graph databases can all be more suitable for a given tasks than relational databases.

You think immigration should be illegal?

You really had me in agreement with the first few items. You are not a serious person.

mr_overalls··on Repairing the U.S. Medical Residency Pipeline
I don't know if I would go that far. University education usually involves a ton of general-education classes for the first two years: English, science, history, math, basic science, etc. High school quality is quite uneven in the US, so these classes are largely necessary, imho.

Also, that's not to mention the many "pre-med" classes that medical schools require for applicants. Are high school kids going to take the organic chemistry, biochem, etc. necessary for med school?

mr_overalls··on Vaccine experts: Covid-19 booster shots aren't needed now
Choosing to risk catching a disease with a 1-2% case fatality rate, while refusing an overwhelmingly safe and effective vaccine is the definition of idiocy.
mr_overalls··on Clinging Desperately to a Metaphor (2011)
I don't see where LeGuin's argument is anything like "we shouldn't grow past where we are now".

She's arguing (rather imprecisely, since she's not an economist) against a narrow version of uncontrolled economic growth that maximizes shareholder value and raw economic output.

And the objections she voices - growing inequality, environmental externalities, etc - are well-discussed within the field of economics itself.

And while humans _are_ generally more well-fed, sheltered, educated, etc. right now than during past times, there are very serious problems on the horizon, due to increasing population, climate change due to burning hydrocarbons, and other factors deeply entangled with human economic activity.

mr_overalls··on The Coronavirus Is Here Forever
> how does covid transmit

It seems likely that they were drinking sewage-contaminated water. Ingestion of contaminated water is the source of a staggering variety of illnesses for both humans and animals. Souce: I work in environmental monitoring.

mr_overalls··on The Ancient Persian way to keep cool
A high ceiling _does_ mean that a modern A/C system has a larger volume of air to cool. And when people renovate high-ceiling houses, installing a "drop ceiling" is very common.

But when fans and cross-ventilation are the primary means of cooling, high ceilings allow the hottest air in the room to accumulate, where it will not bother occupants (and thus forcing cooler air into the occupied space near the floor).

mr_overalls··on The Ancient Persian way to keep cool
The final comments on "AC architecture" are quite interesting. In my childhood home, the American South, pre-1950's housing is highly optimized for cooling. High ceilings, transoms, pier foundations, tin roofs, etc.

When Hurricane Katrina hit and left us without power for two weeks in the summer, sleeping in our normally comfortable home was nearly unbearable, even with every window open. The house simply was not designed for facilitating passive air flow. My friends, who lived in a rather dumpy 19th century "dogtrot" farm house, reported sleeping in relative comfort.

mr_overalls··on America is turning into the Soviet Union
> This new way of thinking — progressivism is probably the fairest term — is far less tolerant than liberalism. Indeed, in its hostility to freedom of speech, its Manichean worldview, its suspicion that its opponents are fascists, and the belief that politics should be inserted into everything — from science to children’s books — it is closer to the totalitarian tradition.

So the American Left are totalitarians? The hypocrisy of this article beggars belief.

Have we forgotten that on Friday, the House oversight committee released notes of a 27 December telephone call from Trump to then acting attorney general Jeffrey Rosen, in which Trump told Rosen: “Just say the election was corrupt + leave the rest to me and the R congressmen.” The notes were taken by Richard Donoghue, Rosen’s deputy, who was also on the call.
