eatitraw··on When starting school, younger children are more likely to be diagnosed with ADHD
> and scares off the approaching deer

And that's exactly the way early humans hunted. The method is called persistence hunting: https://en.wikipedia.org/wiki/Persistence_hunting

Humans run slowly, but human bodies can dissipate heat very efficiently through sweating, and this makes humans good long-distance runners. AFAIK, humans can outrun most other animal species.

So if I understand it correctly, the hunting method involves scaring your prey, running for a while(yay hyperactivity), using your big brain to figure out where the prey went and running again for a while. Rinse and repeat for many hours, until the prey literally dies from exhaustion.

I imagine persistence hunting as a series of puzzles while you literally can see your reward - no delayed gratification involved.

> All of these are also side-effects of over use of amphetamines...

Surely you are not the first person with this idea? Could it be that other people thought this too and compared unmedicated and medicated ADHD populations?

ADHD is heavily underdiagnosed in the adult population, hence it is not hard to find adults who have ADHD and who never took stimulants. IIRC, The studies show that kids medicated with stimulants actually have lower rates of substance abuse.

> 2 - Okay all psychiatric disorders use checklist and interviewing, but that may reflective of a problem with modern psychology.

And this problem being what exactly?

> It's very hard to say with any objectivity how much happiness, calmness, or attention is proper when your life situation may be bad, stressful, or boring.

And your solution is what exactly? Do nothing?

The reality is that it's not easy, but certainly not as hard as you make it to be. Most psychiatric diagnoses (including ADHD) have decent inter-rater reliability. They are certainly going to produce some amount of false positives and false negatives. But the moment humanity invent magic test for depression/anxiety/ADHD/etc, psychiatry is switching to it.

> So even if there is a biological condition that stems from brain differences, what is the R^2 between professional diagnoses of ADHD and actual biological cases of it?

Like I mentioned, brain scans are not really used for diagnosing (yet), because they are not sensitive enough to be used for diagnosis. How would you compute R^2 in this situation?

> Anyone is going to start questioning things if they see kids with a diagnosis who seem basically normal.

How do _you_ know if they are normal or merely seem normal though? What is your definition of normal here?

eatitraw··on When starting school, younger children are more likely to be diagnosed with ADHD
Spot on. I wish ADHD had a less cute sounding name, maybe then people would take it more seriously. And it is also a misnomer: it is often about being unable to regulate attention (rather than simply having a lack of it), which leads to mysterious variations in productivity, especially with tasks that are not novel, interesting or challenging.

What's your point here? ADHD brains are still there. You can choose not to medicate yourself if you don't want to.
eatitraw··on When starting school, younger children are more likely to be diagnosed with ADHD
There is a 'hunter vs farmer hypothesis'. It is certainly a cute idea. But even if it is true, the society isn't going back to back to persistence hunting.

There is some real human suffering right now (simply by definition from DSM - if there is no impairment, it is not ADHD).

"I guess I picked the wrong time to be a human being".

I am really surprised at all the skepticism about ADHD in this thread.

1) Attention (or executive functioning in general) is normally distributed, just like a lot of other human traits. If you don't doubt that intelligence is normally distributed (and that some people are smarter than other), what makes you think that there is no variability in executive functioning / attention?

Executive functioning also improves as brain develops, and that's why problems of younger kids are probably more noticeable.

2) Re: diagnosing using checklists and interviewing. That's literally how every other psychiatric disorder is diagnosed. Depression? Checklists and interviewing. Anxiety? Checklists and interviewing. Schizophrenia? Also checklists and interviewing.

Studies show that there are measurable differences between ADHD brains and normal brains. People complain that these are not used for diagnosis. The reason these scans are not used for diagnosis is because the resolution of common brain scan methods is not high enough, and these differences are seen on the population level.

3) Some graphs on brains differences: https://adhd-institute.com/burden-of-adhd/aetiology/neurobio...

Really cool and fun game. I really wish there were more levels!

Also, like some people suggested, it'd be nice to have an option for running the game at a higher speed.

eatitraw··on Should Rivers Have Rights? A Growing Movement Says It’s Time
> Should they be imprisoned?

No, because other animals don't have mental capacity to truly understand the consequences of their action.

That said, I've never really seen a consistent argument against _protecting_ prey animals from lions (and letting lions die out).

eatitraw··on Chaff Bugs: Deterring Attackers by Making Software Buggier
Imaging having a bug in your software that introduces bugs. Instead of introducing new non-exploitable bugs, it introduces exploitable ones.

This would probably be a nightmare to debug.

eatitraw··on Archiving your website in the Wayback Machine
You actually need to worry, because ids are personal data.

Eve you abandon all these social media platforms and use emails for login, email addresses are still personal data, and you are still processing it.

Except that if you add "login with" button then you are suddenly start processing personal data (even if you only store social media ids).

Have you actually tried to read and understand GDPR before getting to this level self-righteousness?

A blog writer wants an easy way of tracking popularity of their posts. Clearly I need a protection from this.

The internet is worse off after GDPR.

> So, if I paid someone $1 to commit murder then it wouldn't be egregious?

A straw man. Stealing $1 is certainly isn't as serious than stealing $100k. And creating malware is closer to theft rather than murdering people.

eatitraw··on How We Built r/Place
Ah okay then!

BTW, thanks for the great post, it was a very interesting read.

eatitraw··on How We Built r/Place
> We used our websocket service to publish updates to all the clients.

I used /r/place from a few different browsers with a few different accounts, and they all seemed to have slightly different view of the same pixels. Was I the only one who experienced this problem?

When /r/place experiment was still going, I assumed that they grouped updates in some sort of batches, but now it seems like they intended all users to receive all updates more or less immediately.

eatitraw··on How real are real numbers? (2004)
Even though you defined the number, you can't really do usual stuff with it: e.g. you can't compare it to other numbers.

IMO, these kind of numbers are no more "real" than infinitesimals: https://en.wikipedia.org/wiki/Hyperreal_number

There are various flags of different anarchist movements, very long trans* flag, LGBT flags here and there. IMO, all these count as "actually political".

eatitraw··on Heroku is no longer the hobbyist's friend
> I'm wondering if there are any recommendations for "Heroku-like" providers with a free tier that stays up 24/7 for super simple Rails and Sinatra apps, perhaps with a DB.

OpenShift(https://www.openshift.com/) may be the service you're looking for. I haven't tried it, but it looks nice.

This works sometimes! Thanks
eatitraw··on Ask HN: The best way to move an existing long-running process between terminals?
I am aware of screen, and in fact, it'd be nice to move the process into a screen or tmux(and I mention this). The process is long-running, and I'd like to keep it running(instead of killing it and starting in screen/tmux)
eatitraw··on Ask HN: The best way to move an existing long-running process between terminals?
The whole point of my question: you have a _pre-existing_ long-running process that you don't want to restart.

I am aware of screen and tmux, in fact, I explicitly mention that I'd like to move the process into a tmux:

> ideally, you'd like to move this process inside a tmux
