jhayward··on Ask HN: Interesting TUIs (text user interfaces), maybe forgotten ones?
The `rich` module for Python is remarkably complete and lets you code at a very high level - even has CSS. Rich's sibling, Textual[1] is designed for building TUIs.

Attributing casualties from a dam break as energy-related is a stretch. The vast majority of dams are built for flood control. Energy production just helps pay the bills. It's not the 'purpose' of the dam.

You mean like Ford's Mustang Mach-E, that starts at $40,000?

I'm not sure what purpose the hyperbole serves here.

jhayward··on Why isn't dental health considered primary medical care?
I should have said "dentists and optometrists", rather than " .. and opthamologists". Sorry to catch this so late.
jhayward··on Why isn't dental health considered primary medical care?
I don't recall who first relayed this to me but I believe the answer to the question in the title is "path dependence". Modern (US) health insurance started off as hospitalization insurance and was originated by hospitals themselves. It covered hospital procedures such as surgery etc.

We should note that dentists and opthomalogists do not typically operate from a hospital setting, at least not in the early (1920-1950) era.

Over time it was spun out of hospitals and extended to more medical procedures. The tax advantage of having employers pay for coverage began to dominate the market and has led to the current state of the medical marketplace. But the original dichotomy remains. "Health" insurance covers things that doctors do, and mostly those things that happen in hospital settings.

There is an interesting article [1] that has some of the history of group health coverage which I found just now.

jhayward··on LAPD officers told to collect social media data on every civilian they stop
This could only be said by someone who is completely disregarding the coercive power of a police "interview".

There is always, always, a subtext of "if you don't wish to cooperate, I may need to exercise my discretion to ...", with the ellipsis being anything from literally tearing your car apart in a "reasonable suspicion" drug search, to some made-up traffic infraction, to anything else that police are trained to use as coercion.

Just because you have some theoretical rights that a judge may at some point months later grant you, doesn't mean the officer can't violate the hell out of you right now and probably get away with it - and end up getting a baseless conviction, or a paper trail in police records, or just make you late for your job interview.

All of the demographic change is essentially growth in the Hispanic population. The Hispanic demo votes overwhelmingly conservative.

No, it won't. Austin is one of the most gerrymandered regions of the country.

I live in downtown Austin. My congressman is Chip Roy, an ultra-right-wing MAGA nonsense spewing idiot.

jhayward··on How Computationally Complex Is a Single Neuron?
I believe they modeled the behavior of a model of a neuron, not an actual neuron. Models are intrinsically simplifications of the reality.

Let me reverse your question: why would you use "how much oligarchic wealth someone has" or, possibly, "how intent on money laundering the buyer is", to determine aesthetic value?

Because that's how art is sold today.

jhayward··on Glean – System for collecting, deriving and querying facts about source code
The wiki page says ctags was part of the 3BSD release, which would put it about 1979. My memory isn’t good enough to recall which release of emacs picked up support.

I think there was a find-function key binding for lisp code before ctags, but these are very rusty bits I’m recalling.

jhayward··on Apple banned a pay equity Slack channel
I once made the mistake of making an offhand remark about people "aren't sitting around watching the dogs channel" in a meeting.

Oh, did I get some dirty looks from that ill-considered thought that was spoken aloud.

jhayward··on ‘Building back badly’: Global power sector emissions soar
City or County denies occupancy certificate due to no electric connection and he's on the hook for all the mortgage, plus liable for the bank's losses because the house is un-sellable plus he has to find somewhere else to live until it is corrected.
jhayward··on FDA Approves First Covid-19 Vaccine
> some hospitals in Texas have started using it during triage

This is false. The "leaked" internal discussion document has been repudiated by its author, and the group of hospitals discussing it.

Only someone totally ignorant of the difference between a vaccine and a pain drug, in terms of how they are tested and approved, would use 'what about vioxx' as an indictment of vaccines.
jhayward··on Peru is reviving a pre-Incan technology for water
There is a really interesting example of the role of the surface vegetation for groundwater in Bamberger Ranch[1] in Central Texas.

Central Texas was massively overgrazed by cattle in the 1800's and 1900's, and the ecosystem was completely transformed from prairie grass dominant to cedar and mesquite dominant vegetation. This resulted in a drastic loss of groundwater and utterly transformed the ecosystem.

David Bamberger restored 5,500 acres to close to original condition and the results are amazing.

jhayward··on AstraZeneca Scientist Says Delta Variant Makes Herd Immunity Impossible
The role of cellular immunity isn’t as clear. What would probably make a big difference, though, would be mucosal immunity given by a nasal vaccine. Get those antibodies located at the point of infection and they can get to work earlier.

jhayward··on AstraZeneca Scientist Says Delta Variant Makes Herd Immunity Impossible
> but are those mutations antithetical in some way to antibody production?

The problem Delta presents to antibody-based protection is that there is a several day lag in the body's response to detecting the virus until it produces mass antibodies.

If the (small) number of circulating antibodies are overcome by a large viral load, and if the virus becomes transmissible in a shorter time period, it can "get inside the curve" of antibody response and result in a transmissible infection before the host mounts a full response. Delta is apparently a couple of days 'faster' than the previous Alpha strain in getting to the transmissible stage.

NCMEC isn't really an NGO; it is an agent of the US government, written in to US law.
jhayward··on The deceptive PR behind Apple’s “expanded protections for children”
How is it that you are going to "wait and see how good their neural hashing is"? Do you think there is going to be any shred of transparency about the operation of this system? It is completely unaccountable - starting with Apple and going on to NCMEC and the FBI.

A JPEG is a "visual derivative". It's also a "mathematical fingerprint" of an image.
jhayward··on AstraZeneca Scientist Says Delta Variant Makes Herd Immunity Impossible
That's what I want to know. A mucosal vaccine would be a very effective counter to the ramped up viral load and shorter incubation period that delta has brought.
jhayward··on AstraZeneca Scientist Says Delta Variant Makes Herd Immunity Impossible
Yes, the vaccines are still very effective against severe disease. It is transmissibility that's changed dramatically.
