Years ago as part of my thesis research I created a rather obscure family of data structures called DFI Filters or DFilters for short. The work centers around indexing typed trees such as abstract syntax trees or a web browser DOM such that you can answer arbitrary queries of the form "give me the set of all descendants of node P that are of type T" in something that in practice collapses to O(1) in the number of tree nodes. There are several versions of the data structure, but the general setup is a sort of "tree of trees" where the main tree is a binary search tree organized based on the depth-first indices of the nodes in the tree being indexed, and there are links into each type-specific variant of the main tree (in other words, simplified versions of the main tree containing only one type). The key intuition behind the whole thing, and the reason I called them DFI Filters, is the fact that if you are at some particular node in a tree, and you know ahead of time the depth first indices of your node and it's siblings, you actually already know exactly how many descendents your node has based on the difference in the DFI number between your node and its depth-first successor. Then you can build a variety of indexing approaches and data structures based on this insight -- I came up with ones that do it in truly constant time but are expensive to update as an undergrad, and in grad school I was able to build a version that updates on the fly but still retains ammortized O(1) for querying and ammortized O(m) for updating where m is the size of the update.

By the way if you're curious how I can get constant time when I'm returning a set of descendants, it's because I can give you the size and pointers to the first and last elements right off the bat.

The link to the original paper seems to be down (looking into it), but you can find the master's thesis covering all variants here: https://github.com/sam0x17/hierarch_old/blob/master/Master's...

I've been working on a rust implementation lately as well. There are a number of applications for DFilters including fast file-system searching, DOM traversal, very fast static analysis on abstract syntax trees, and more.

> All my guitar playing friends watch the same fucking videos on Youtube

I see the echo chamber effect in a lot of these communities. You need one of the 5 approved amps for X style, or are you even a guitarist? These arguments amuse me more than anything.

But is everybody really like that? If I'm watching YouTube videos on guitar gear I'm trying to get a feel for something, and then I try stuff. Sometimes I agree, sometimes I don't, but at the end of the day I choose what I like.

I hadn't played in quite a few years and am recently back at it. Back then, I certainly owned things the Internet community collectively agreed sucked. Now that I'm back at it, some of this gear is now considered good to great, and I have to laugh about it. No regrets for having my own opinions.

I don't have many friends who play though, so perhaps being all on my own shelters me from the monotony. Or perhaps you need to find different people?
Interesting read. I think something that bothers me more than trying to remember passwords (I have a system) is when an app or website won't let you see what you've typed! It's so easy to make a typo, especially on a phone and nothing infuriates me more than that "wrong password" message popping up when I can't even view what letters/numbers I've typed in before hitting enter.

And yeah it would be great if scientist didn't had to publish results for the sake of it. Especially in medical sciences meta studies are super popular cause you can do them with library article login and spreadsheets, which end up in a lot of articles with strong conclusions on a mismatch of data. Meta review definitely have their place but they are as far removed from the clinical reality as can be.

> Because it requires the devotion of Apple's resources to supporting non-Apple things. It will necessarily degrade certain experiences away from those that Apple would provide without the regulation.

The first point (about Apple's war chest) is that they have plenty of resources.

The second point (about how they conspired to cheat their own engineers despite having more money than Scrooge McDuck) is just to remind everyone that these are amoral money-grubbing bastards who will do pretty much anything they think they can get away with to make a buck.

The idea that opening up their walled garden to competition will "degrade certain experiences" is laughable.

It's due to administrative fish protection issues. Cooling a 375°C reactor with 40°C water (or even 60°C) is not a big problem. Keeping water temperatures below fish protection discharge limits set decades ago is harder. In heatwaves, the authorities relax the fish laws.

I have a policy that is to support at most three releases back.

Requiring upgrades to support new software is normal. New APIs are released, new features that allow for simpler code or remove unneeded unsafe blocks. These are good things.

People don’t need to install the latest software. If they want to install the latest software, then they will need to install the dependencies that support that software. That can be operating system versions, compiler versions, or other library dependencies.

I really don’t understand this mentality of wanting to update one piece of software, but also not wanting to update any other software it might depend on.

"But then yeah, after that day, when, you know, Bitcoin went from $30,000 to $20,000, you know, that, that was extremely painful for us. And that was in, that ended up being kind of the nail in the coffin."

Bitcoin has had 10 drawdowns of 40% or more in its short history of 13 years [0], and yet a mere drop of 33% caused them major problems. Doesn't sound to me like they can blame "a systemic failure of risk management"; more like a profound lack of understanding by these two individuals.

IIRC, if the industry can compete in an interstate market, it falls under the interstate commerce clause — even if the business only operates within a single state. So even forcing data to operate within a single state border would still not protect the bill. At least, that’s the theory behind regulating gun manufacturers that only operate with a single state. IANAL, but I don’t know if this theory has ever been tested at the USSC level.
Part 1:

On a naive interpretation, "recycled tub" is a health hazard.

Clean water is clean because the drain is separate from the supply.

You really really don't want sewage in the water you drink.

And if you put bath water in a potable supply pipe, you will because bath water has had someone's butt in it and pressure differentials create backflows (i.e. siphoning) in the potable water pipes.

Without an air gap, you cannot prevent it.

Part 2:

Limiting the supply would be a simple matter of adding a valve, except that a bathtub has two supplies, hot and cold.

Getting the mix right is safety critical because hot water creates a really nasty type of burn...enough that can kill a person.

Part 3:

There's a reason plumbers are licensed.

It's not greed.

It's because you didn't ask "how do I prevent backflow?"

Part 4:

Putting something connected to mains power into a bathtub is a bad idea.

It sucks if your fish die from an electrical short.

But not like if it were your child.

Part 5:

You could rig up a mechanical pump and let your child pump their own bath water to their hearts delight.

Seems like the simplest thing that would work...where working means not being a health hazard.

As a bonus a mechanical pump can be put in a suitcase and taken into a hotel room.

Part 6:

Good luck.

When I first got into distributed source control I found Mercurial much easier to use. Even though Git has "won," threads like this are a good reminder that there are git bridges for Mercurial that allow you to run Hg locally and then push/pull/branch/etc with a Git remote repo. I need to look into that again.
I wonder whether clinical trials can even select correctly candidates who are "depressed".

I'm manic-depressive/bipolar and there's a clear behavioral marker that doesn't happen as a result of despondency over negative life situations: mania. Clinical trials for manic depression are much better, and the gold standard -- lithium -- is known to work for most people. If you go back into the history of psychiatry, the touchpoint where it starts to sort of look like medicine is when Kraepelin develops a differential diagnostic method to sort out manic-depression from schizophrenia. It's very hard to see something like that for depression.

To compound: American psychiatry is especially bad because it fell for psychoanalysis hard, to the point that it seemed like NYC had higher rates of psychosis than London because Americans had deviated from the standard definition of psychosis to use Freud's. Who knows what passes for "depression" in the US.
> mental health and medications.

The individualization of mental health problem misses that there are very likely systemic causes of depression.

I've gone through several severe periods of depression, and at the time it all seemed like something was wrong with me and this is the prevailing narrative. In retrospect all of these were caused by a very real external problem in my life that I didn't see (depressing job, emotionally abusive parents, unhealthy marriage etc).

I have no doubt that had I sought medication in any of these cases I would have been given it. But that would have prevented me from being forced to realize the very real problems in my life.

In a broader perspective there are plenty of wide spread social issues that are very likely legitimately causes depression. The idea of simply medicating this away is akin to simply giving Tylenol to someone who has a abscessed tooth. I'm horrified at the wide adoption of medications (often with adverse side effects) to mask what are very real and legitimate sources of depression.

A better alternative is to openly discuss and challenge the prevailing social issues leading to a mental health crisis.
One would thought a C replacement in 2022 would have better hindsight regarding memory safety than what was already possible in 1978, which was actually even available in JOVIAL (1958), or ESPOL/NEWP (1961), among many other possible examples.

No reflog, but there is the obslog, which stores obsolescence history of individual revisions. Better yet, the obslog is distributed during pull / push. Because Mercurial knows precisely which commit is replaced by which commit, it can automatically resolve a lot of conflicts that result from history editing.

Have a branch-a that depends on branch-b that depends on branch-c that upstream just rebased and squashed some of its commits? More often than not `hg pull && hg evolve` is all you need to do to synchronise everything. This makes stacked PRs much easier to manage.

Teaching a Neural Network to Play the Atari Breakout Game
I actually learned just recently that most of our energy consumption goes to creating heat or cooling, like 70% or something. So right now we are creating electricity to convert to heat or cooling, while we technically could just store the heat instead. A large enough pool of water could store heat for long periods (months) with minimal energy loss. So the notion that energy from renewable sources such as the sun can't be stored effectively is not true, and in fact the big part of our energy needs could be stored this way.

No they weren’t. They were a fringe treatment that was popularized by stigma and prejudice. The fake science and the torturous nature behind them were called out many times by real scientists at the time, and simply ignored by health authorities.

Heck. Just watch how the treatment was portrait in a Hollywood blockbuster in the 1970s. There is no way One Flew Over the Cuckoo’s Nest would frame lobotomy so badly if it was consider a “golden standard”.

Comparing SSRI to lobotomy is a historic revisionism at best.

This is basically what happens when the entirety of western governments is run by lawyers, teachers, and BA consultants. There is a massive lack of critical infrastructure engineers that should be welcome in government or at least close advisors of the government but no longer are. Note that for all the terrible parts about China they have a lot of engineers in their government, leading to a lot of critical investments in infrastructure.
Having had depression for over half of my life, I’ve never believed it was a chemical imbalance. For me, it’s a complicated function of thoughts and feelings that lead to depressive mood. Some I’ve been able to address and get better, some I have not.

I will say that depression meds have helped me in the past from going too low. But it never fixed depression, more like a safety net.

So this friend of mine is currently reading a history book in French. Full of acronyms, not recognizable in the current international use. SMI, DTS, OPEP, OTAN, OCDE...

These dots don't connect for me very well in this article:

> In 2006, Schrag’s first publication examined how feeding a high-cholesterol diet to rabbits seemed to increase Aβ plaques and iron deposits in one part of their brains. Not long afterward, when he was an M.D.-Ph.D. student at Loma Linda University, another research group found support for a link between Alzheimer’s and iron metabolism.

Yet, fast forward to December 2021 or early 2022:

> Three of the papers listed Lesné, whom Schrag had never heard of, as first or senior author.

If Schrag was doing research in the same area, at around the time Lesné's results started to dominate, propelling his career, it's odd that Lesné's existence somehow eluded Schrag for 16 years.

Did Schrag switch to something else at around that time and never give it a second thought for a decade and a half?
From the article: "South Carolina state senators introduced legislation that would make it illegal to “aid, abet or conspire with someone” to obtain an abortion."

This bill isn't law, which is what I thought based on the headline.
Strictly speaking, that's exactly what clinical depression is, as opposed to 'distress'.
> The same way a government turns around and says that things like child pornography, human trafficking, terrorism, hate speech, bullying, piracy are not allowed on the internet.

I'm not so sure. Those are all things that most people consider to be bad, and that most countries have laws banning, or there's at least enough overlap between countries and languages to keep it mostly out of the mainstream internet content in certain languages.

These work because South Carolina doesn't have to "police the internet", instead things like FBI takedowns work, countries spend a lot of money on targeting trafficking organisations, and because companies like Twitter/Facebook/etc have some respect for national governments where they want to be able to conduct business.

What are SC going to do in this case? I guess they could prosecute sales of ads for these websites by companies based in SC, or maybe prosecute hosting providers in SC who are hosting these sites, but these are pretty weak actions.

Unless a large number of other governments get behind them, or they decide to build a Great Firewall of South Carolina this is going to have roughly zero effect.
> For the NRLC, which wrote the model legislation, limiting communication is a key part of the strategy to aggressively enforce laws restricting abortion. “The whole criminal enterprise needs to be dealt with to effectively prevent criminal activity,” Jim Bopp, the group’s general counsel, wrote in a July 4 memo, comparing the group’s efforts to fighting organized crime.

This basically tells you everything you need to know. These people want to put women in jail and they don't care about niceties like "inter-state commerce" because in their mind they're fighting Al Capone. I hope commenters on here stop minimizing what these groups are trying to achieve. The reversal or Roe was not about "kicking it back to the states", it was the first step in trying to make abortion access illegal nationwide.
