I think your original anecdote that the advice seems to cycle is likely very specific to your situation. My wife is a pediatrician and she's certain that in the US at least, the recommendations both official and actual haven't cycled for decades.

I don’t see anyone talking about paying people to be your friends.

People like to drive outside the city to hike, travel, go to restaurants, movies, bars, ballgames, museums etc...

You don’t need to spend a huge amount on social stuff, but if you are only willing to do completely free activities, you are vastly limiting your social circle.

If you’re poor, most of those things require some non negligible percent of your income—-if only just in gas/transportation.

But more importantly they require time away from working/studying/optimizing for bank account balance.

What country are you in? That’s definitely not common in the US.

Running across a doctor telling you to do anything other than back only sleeping is like running across a doctor telling you that vaccines cause autism. I’m sure it happens, but it’s very rare.

learc83··on Confessions of an Unreal Engine 4 Engineering Firefighter (2018)
In addition to large binary asset files, in Unity you have tons of yaml files that you don’t edit by hand. If you make a small change to a scene with the editor, it can change dozens of lines in the corresponding yaml file.

Now imagine 2 people working on the same scene. When you attempt to merge, you have to read and understand an auto generated file that was never intended for human consumption.

To a lesser degree, it’s analogous to using line based source control on a jpeg to handle merging edits made in photoshop.

Back only sleeping has been the recommendation of medical authorities in most of the world for close to 30 years.

It’s not a recommendation that changes every few years.

learc83··on FDA approves first test of CRISPR for genetic defect causing sickle cell disease
But is malaria a big enough problem in the arctic to bother targeting the mosquito species there that could carry malaria? From a quick Google search, I'm guessing no.
learc83··on FDA approves first test of CRISPR for genetic defect causing sickle cell disease
Do all the species of mosquitoes your talking about feed on humans, and do they carry malaria?

Audio is what was breaking. Also WebGL outperforms canvas, and it’s more complex than drawing a bitmap to the screen.

It wasn’t my code, it was engine code, and it was a problem where Safari reports that it doesn’t support a feature that it actually does.
learc83··on Godot Engine Web Editor
This is very true. I built a game to go along with our wedding invitations. I’ve been maintaining it for the past 6 months, and it has stopped working on one browser or the other multiple times. This is despite the fact that I’m using a popular actively maintained JavaScript engine.

It noticed just a few days ago that is wasn’t working on my iPhone because mobileSafari decided to stop reporting itself as safari and only as “mobile safari”.

You have a control group of unvaccinated people.

The “public shaming statement” says explicitly that if someone from the company contacts them, they’ll give it back.

That’s probably the quickest way to get the website back to them.

learc83··on Declassified spacecrafts and orbital weapons of the USSR (2018)
The claim that we have (or had) enough nuclear weapons to cause the actual extinction of humanity, much less cause it several times over, is dubious. If you google it there are numerous articles debating it. At the very least there isn’t scientific consensus.

learc83··on The nation’s oldest juvenile lifer, Joe Ligon, left prison after 68 years
You're not going to find the solution buried in a random hacker news comment thread.

But step one is to acknowledge that systemic racism exists in the first place. Half of the voters in the country explicitly deny the existence of systemic racism and the need to change anything at all.

learc83··on The nation’s oldest juvenile lifer, Joe Ligon, left prison after 68 years
Even when controlling for other factors like education (a proxy for income) and criminal history, Black male offenders receive a sentence 20% longer on average than White male offenders for the same crime. They're also convicted at a higher rate for the same indictments, and arrested at a higher rate in the first place.

learc83··on America's 1% Has Taken $50T From the Bottom 90%
>Who cares about gold? Who cares about avoiding math? Not me. I guess I am no Austrian for those reasons.

The people who wrote those books that you said would support your argument certainly do.

>I’ll be happy to get my (Of course discredited) books out and recite the counter case about the Great Depression if anybody really wants me to later

>I do care, however, about restraining the inflationary tendencies of governments because I believe they are an engine of wealth redistribution from the poor to the rich and powerful.

Are you basing this belief on anything other than gut feelings and the work of Austrian economists who's books you've read? von Mises is an absolute crackpot, but he does a very good job of making you "feel" that his arguments are valid.

>And sure, I suppose I do care about avoiding mathematical naval gazing, or statistical hackery.

That's different than the Austrian position that mathematical analysis is impossible and harmful. Without accepting the basic premise of Austrian economics that "no measurement is possible" and everything can be derived from the first principle of "humans acting with purpose", the rest of their "proofs" are worthless. You can't just accept (and cite) their arguments while also acknowledging the fundamental flaws with the axioms they use to reach their conclusions.

learc83··on America's 1% Has Taken $50T From the Bottom 90%
If you're talking Austrian economists, who are the primary proponent of the "fed is the bad buy, bring back the gold standard" argument, they explicitly reject any attempt at modeling or mathematical analysis. They are only interested in arguments based on "self evident" axioms.

I've read many of the books you're talking about, and there's a reason they are "unpopular" and “discredited".

learc83··on The Vaccine Had to Be Used. He Used It. He Was Fired
Not only was there no such policy in place according to the article, but physicians are given wide latitude in making medical decisions (using drugs off label, using expired drugs etc...).

If they act unethically, there is a built in method to address this through the licensing boards that regulate them.

Criminal behavior is different, but the Judge that heard the case completely rejected the argument that the behavior was criminal.

learc83··on The Vaccine Had to Be Used. He Used It. He Was Fired
According to the doctor that was explicitly not the policy. His version is that the health department made it clear that they should do whatever they had to do to keep from wasting doses.

This lines up with what I know from family members doing vaccinations in other areas.

learc83··on The computers rejecting job applications
I’ve worked in the HR tech space and we integrated with all of the big applicant tracking systems.

Many of them have screening questions. So you can ask something like “can you lift 50 lbs?” And set it up so answering no will screen the candidate out. But even in that case recruiters and hiring managers will usually still look at the candidate anyway.

There are also 3rd party addons that will score candidates, and resume parsers that will let recruiters search resumes for keywords.

But as far as I know there are no widely used AI solutions that will actually flat out reject candidates with no human intervention.

Even if it worked, the risk is too great that your model will start over rejecting people from protected classes and no one will notice until you’re hit with a lawsuit.

learc83··on Tesla buys $1.5B in Bitcoin, may accept it as payment in the future
Yes there exists jewelry that can be bought mainly as a store of value, but your argument was the much stronger statement:

>Another thing to consider is that people buy gold jewellery as a store of value. You don't spend $30k on a watch if you don't think it will keep its value.

This isn't true because the vast majority of retail jewelry, which is the majority of jewelry sold is a terrible store of value.

The average person that spends say $10k on a diamond ring isn't going to be able to get that value back again. Even beyond the issue with how much it's marked up, there's the problem that jewelry stores tend to sell on consignment, so they have little incentive to buy and resell used jewelry.

And if you look specifically at gold watches, a small fraction of the price is actually the price of gold itself.

According to this link https://www.montredo.com/how-much-gold-is-in-a-solid-gold-ro... a 30k Euro gold Rolex only contains about 4k Euros worth.

This link says something similar https://millenarywatches.com/how-much-gold-in-rolex/

A $30k gold Rolex contains about $5k worth of gold, yet it costs $22k more than the non gold version.

learc83··on Tesla buys $1.5B in Bitcoin, may accept it as payment in the future
If they do that, they’ll need to follow the same regulations any other bank does.

>You don’t spend $30k...

Yes you do. You’ll almost never get the retail value out of a piece of jewelry if you try to resell it.

learc83··on Peter Naur's view of programming
Dragon works very well for dictation, and a Wacom style tablet works great as a remote substitute for whiteboarding.

There are also voice coding solutions like Talon voice that work well (I use it regularly).

learc83··on Navy speaks up about its “UFO patent” experiments
Right that's the point--there's a mismatch. The number in the original article likely includes benefits and overhead. The person I'm replying to is posting numbers from glassdoor and other places that most likely don't.
learc83··on Navy speaks up about its “UFO patent” experiments
“Salary” numbers almost never include benefits like health plans and pension contributions, and they definitely don’t include things like unemployment insurance payments, and payroll taxes.

I have never seen salary used as the total cost of an employee.

learc83··on East Coast Internet Outage
You should move down to Hamilton county. We have 1Gb fiber for around $60 from EPB (the municipal power company). Even out in the more rural areas.
