A friend of mine teaches middle school in Japan and he recounted this story of a parent teacher meeting.

A girl, who was by all accounts a decent student, had not been doing some of her homework recently. He brought it up in a casual and supportive way. The mother busy into tears and apologised profusely, exclaiming that she was so sorry for sending such a terrible didn't to this teacher's class etc. As this goes on the daughter now starts crying in response.

My friend said this is a scene repeated again and again. Enormous amounts of pressure from both the parents and the teachers (he is something of an exception) is crushing children.
> You may be misunderstanding my comments. I'm describing use of the blob column type to store serialized data for unindexed fields.

I understand perfectly. This is a very inefficient use of RDBMS. It violates every single normal form, and will lead to all of the performance bottlenecks I mentioned.

> This has nothing to do with foreign key constraints or check constraints, which are implemented entirely at the application level

As I stated before. This is not an RDBMS, it’s simply using RDBMS components as a storage service. An RDBMS must enforce key and check constraints, if this is enforced entirely at a higher level then you’ve violated the nonsubversion rule, and you’re dealing with a system that is not an RDBMS.

An RDBMS can only be called so if it conforms to Edgar Codd’s relational model, that is the exclusive definition of an RDBMS. Simply managing relational data on some level does not make an RDBMS, excel does that and it’s certainly not an RDBMS. So does MongoDB, and it’s not an RDBMS either.
Yes both. One of the pilots (Fravor) went on Joe Rogan. He said his buddy stayed up circling and was also able to eyeball the craft. He wanted to get up close to it, and she covered him from above. Apparently his buddy got really disturbed and angry about the whole thing--that this stuff has been going on and that they weren't warned properly about it.

They both got the idea it was just a 'weird little thing' from the ship's radar operators, but when they actually saw it they both were obviously kind of gobsmacked. The unnamed female pilot apparently got kind of outraged that there was no procedure or information being shared in an organized way. Like nobody knows really what to even do in these situations because it's not really seriously talked about.

Like I said, the radar operators were seeing these things before the pilots even got into the air. So that rules out dust.

I was thinking more some kind of Russian disinformation operation--a low mass kite kind of craft remotely powered or towed by a fast underwater sister drone. Both operated from a submarine for example (Fravor reported large wave disturbances below the craft that did not match the craft's shape).
No, it’s the appropriate measure of ”unfairness.” If you designed a system where 5 black guys got misidentified but 1 white guy, out of the U.S. population, that would be far less unfair compared to 2%/1% despite the ratio being higher. And why did you pick that ratio to compare instead of 90%/80% vs. 99%/98%? The right means of comparison — for fairness — is the absolute difference in proportion.

I don’t mean to imply that’s the right metric at all, of course, because it specially privileges minorities. The proper measure should equally weight the algorithm’s performance on all people in the population, or at least weight them irrespective of race. That’s just not a measure of fairness between races.
And when you shake it, in russian language it asks “Don’t apply typing of text” with buttons “Don’t apply” and “Cancel”. Years before its title was “Don’t apply (Input)” with same buttons.

Maybe because in russian Undo == Cancel and they had no courage to make it “Undo”: “Yes” - “No”.
This is the main reason why I use Hacker's Keyboard[0] when writing notes, because it has a full on functional keyboard with all modifier keys. Especially CTRL-Z and Arrows keys.

> "But when am I actually going to use this?"

I was as guilty of this as anyone in my school days, and yet not a single teacher ever pointed out to me that I was at school to learn how to learn, so in a sense the subject matter was irrelevant.

That said, while I love Ted's enthusiasm and creative thinking, it's too bad that he didn't seem to roll with the times and learn from what people / the market had to teach. I spoke at a conference with him around 2011, and it seemed he was still fighting UI design battles that were settled in the 80s.

Also, had no idea the TED conference had been around so long. Ted's skewering of it as "smug" indicates it hasn't changed much over the years! :)
TC?
Just copy-pasting neonate's quote from the article, responding to a similar comment:

_That finding was independent of other factors thought to influence life's length — such as "socioeconomic status, health conditions, depression, social integration, and health behaviors"_

Literally the second paragraph on the article.

Read the article before posting comments, folks! :)
I think the older and more competitive a space is, the less likely a first principles approach will bring success.
If work were all unicorns and rainbows, it wouldn’t be work. Employers are businesses so things that drive revenue/profit for them are the work that needs to get done. You can’t argue that figuring out ways to show people more ads is meaningful work, but it has to get done by somebody.

If someone had enough F.U. money saved up to FIRE, you can guarantee they won’t show up for their boss the next day. As it stands, nobody ever goes to work at their current job whenever they get a windfall; they always leave to follow their passions.
It isn’t that different - most complexity theory conjectures are this way.

Basically, there are all these classes of algorithm. P can be solved in polynomial time, NP can be solved in polynomial time by a computer that gets really lucky with rng, PSPACE can be solved with polynomial space, L can be solved in logarithmic space. For many of these pairs, it kinda feels like they are not the same, but we can’t prove it.

So in particular we don’t know that P != PSPACE, which is a much weaker statement, and a very similar one, compared to P != NP.

Similarly, we can’t prove there are cryptographically secure hash functions, and we can’t prove it’s hard to factor numbers.

Basically, we just have very few mathematical tools for proving that complexity classes are different. It’s hard to prove that algorithmic problems are hard. We have diagonalization, which shows that the halting problem is impossible and that P != EXPTIME, and that’s about it.

Anyway, I would conclude not that P != NP is a uniquely hard problem, as much as that complexity theory is very young compared to most fields of mathematics, and there are still many statements we can’t prove.
I like that explanation especially the first paragraph.

I don’t understand pharmacology well enough to really know exactly what’s going on, but I’ve always thought today’s ADHD drugs are extremely broad, perhaps even crude solutions to a poorly-understood condition.

Kind of a super broad-spectrum antibiotic versus a narrow-spectrum antibiotic. Today, my (non-medical) understanding is essentially the same as yours, and that we use Adderall and other stimulants to do what you say - push them to the normal side of the spectrum - but at its core it's just messing with dopamine levels.

Having ADHD and being medicated for many years, it's not like the feeling of "being on a drug" ever goes away completely. It's not completely benign like, e.g. taking an allergy pill. It still curbs my appetite, so I have to be careful about scheduling doses (always eat before). There's a bunch of personality changes when the drugs are in my system, mostly stuff that makes you want to just work "heads down" and not talk to anyone, sometimes that's great, sometimes it's not. I wonder if I am less emotional and am more selfish because of being on it so long, I can't imagine telling someone "I miss you", for example, that just seems like an overly-sensitive emotion that I'm not capable of producing. Especially not in a world connected by iMessage and the Internet, where everyone seems like they are right beside you, even if they are thousands of miles away.

Not sure where I'm going with this, but I guess what I meant by "broad action" is that we are kind of killing one person by carpet-bombing. I wonder if in the future we'll have meds that work much better with less side-effects.

Maybe we even have them now in the form of the non-stimulant options, but my doc did not sound enthusiastic about switching from stimulant to non-stimulant ADHD meds.
It would be pretty handy for cryptography to have a better understanding of which problems were hard. P != NP we are already assuming, but if we could use the mechanism on other problems (like knowledge of exponent, discrete log, etc) it would help.
I blame mental illness on the lack of housing and healthcare. Who wouldn’t go crazy in this situation?

Didn't Crystal run into a major development roadblock a couple(?) years ago? Something about a fatal design flaw in the type system which led to exponential blowup in larger programs. I haven't been able to surface the relevant GitHub threads again, but whatever it was, I guess they worked past it eventually.
Lovely, very inspiring to see "not yet another UNIX clone in C", in a language like Crystal.

I created an account and tested the subscription function.

1) The subscription URL starts with http: instead of https: though your site has SSL set up.

2) The subscription URL can only be used by someone who is logged in. To improve onboarding, I think it should go to the create account screen as opposed to the login screen.

For me personally, I won't use (divulge my friend's email addresses to) this software unless it's open source and I can host it on my own server.

If so, it is definitely mind-bending. Makes me wonder what people mean about not being over-ambitious, "avoiding NIH", "worse is better", "minimizing technical risk", etc. Somehow one is made to feel (by no particular person, but by the composite emergent vibe) that there are a hundred and one reasons to be more conservative. I wonder how many people have the audacity to re-imagine their software ground-up, and the technical chops to actually implement it. The verve is refreshing. Kudos to the author, and also thanks.

You go Alex :) I think more people, even supposed "nonwriters," should write more! Jeff Bezos may be a chunk of hot garbage, but his bizarre writing policy is at least something good.

Heck, I recommend everyone set up a blog. It can be totally pseudonymous, that's fine. Just collect your thoughts and write little personal think pieces that you publish into the void. If they gain traction somewhere like HN, great! But it's not the main attraction.

I don't consider myself in a position to judge the validity of anybody's religion.

But I'd ask you this - if a religion's values are good, its practitioners are happy and its role in the community is positive, does it really matter whether the religion is true in an absolute sense? Is the concept of absolute truth even relevant or applicable?

We've all met pious assholes. I've also met truly faithful people that renew my hope for humanity. The practice of faith is one of accepting duality, of not knowing the truth and being comfortable with that. Or of accepting that one person's unprovable truth is different than another's, and being OK with it. Why bother debating the unknowable?

I find that mentoring a novice apprentice (both teaching general domain knowledge and describing specific architecture decisions in projects they’re getting involved in) is a great way to get back to first principles.

The expected outcome is increased human resource so it somewhat offsets the economic costs.

One caveat is that this process requires the willingness to rethink your own established models, and recognising when they might’ve been outdated or incorrect takes some self-discipline.
Perfectly fine as per European standards.
The iPad was my gateway into the Apple orchard. I had never purchased an Apple product until about a decade ago, when I got the first Retina iPad as a gift for someone who didn’t use computers. I was so impressed by how intuitive the device and OS was for them, that I installed macOS in a VM on Windows to try iOS development. I fell in love with macOS (back during Lion) shortly before getting my first MacBook and leaving Windows forever behind, never to return.

Fast forward to a month ago. I purchased one of the newer low-end iPads as another gift for someone else who didn’t use computers.

It was depressing.

The setup process was kinda annoying. No, we don’t want Apple Pay, thank you. I had to enter the Apple/iCloud account credentials multiple times at different points before it stopped asking me to sign in again.

There were a lot of bugs in the system UI and the preinstalled apps.

I had to disable the multitasking gestures because they would be confusing for a new user.

They have removed labels for the Dock icons with no way to restore them, so I had to keep apps with less obvious icons out of the Dock, so they could have labels. Because a flower for photos is not a connection that many people can intuitively make.

I had to explain that dragging down from the right corner of the top edge brings up the brightness control.

Dragging down from anywhere else on the top edge brings up the notifications.

Dragging down on a blank part of the home screen’s background, away from edges, brings up the search bar.

Fuck.
Interestingly apart from the ruby like syntax they seem to be quite different languages from my limited exposure, in terms of the domains they target (elixir - distributed systems, crystal - whatever go/rust are known for minus distributed systems?), the type system (dynamic vs static), deployment story (elixir - mix based, crystal - binary deployment), the standard libraries they leverage etc.

It seems the sum total of them covers a lot of ground from writing quick CLI apps to large distributed systems for developers familiar with Ruby.
There's a reporting segment running now on I believe CNN Asia about Singaporean schools and "kiasu" culture.

In other words, no balance except as an abstract thought. :)

Dude, there are other factors that I'll consider more important than their tribe.

1. Their family's net worth.

2. The high school they attended

If there's is a high level of creativity in their tribe, then I'll lean towards the idea of creativity boosting cultural practices than genes.

In Nigeria for instance, the Hausa aren't known for their intelligence, and have a reputation for being plain dumb but very violent especially for religious causes (Islam).

The Yorubas are known for being bookworms - they have the highest rates of schooling in the country. And are quite political.

The igbos are known for their entrepreneurship prowress. They tend not to value schooling and are blunt with their words. They claim to have a jewish ancestory.

Someone who's not familiar with their history would claim these differences to be genetic. However, some historical accidents and cultural and religious differences are key.

The igbos have the highest rate of apprenticeship in the country. And they embody the phrase, "Money talks bullshit walks" to a fault. This explains their business acumen. Their language doesn't have honorifics unlike the yorubas.

The seas brought Europeans to the southern part of the country where the Yorubas dwell and for a long while, the capital of the country was located there too. Hence the value for schooling and politics.

Add Islamic schools, very hot weather - and a religion of marrying many wives at an early age and you get the Hausas. They make up the majority of the army as being a soldier is about the only path to a better life.

Conclusion, you'd need to study the history and culture of the Ahskenazi before claiming a genetic predisposition to creativity.

Never in a million years. I booked a hotel in Hollywood, specifying a king size bed through Expedia, and I had to go around with the hotel management about it to actually get the king size bed. They told me that the booking they got from Expedia was not specific. That was the last time I used Expedia. In fact I won't use any of the booking sites because I don't need the complication of wondering who is responsible for a problem.

The assertion you're making is a testable idea. You can check if some apparent trait is genetic or cultural by looking at children adopted by other ethnicities.

They've done quite a number of studies like that, including studies on identical twins adopted by different parents, which gives you matching DNA.

The reason scientists aren't saying such things, is because it's pretty clearly wrong.

One issue I see, is not having customisation for pages. This is standard on book readers and I can't read books with a white background. Also find the text size frustrating.
My experience has been the opposite. I've rarely met anybody in the center ~80% or so that didn't have a little dictator inside of them, yearning to come out and strangle the masses under behavior controls, dictating how everyone else is to live. I find it doesn't take more than a few minutes of conversation with moderates, before you can see the gleam of dictator in their eye, where you can get them to openly state something about wanting to directly or indirectly control other people and how they live.

And when it comes to the extreme partisan wings, the dictator is giant rather than little. You don't have to engage them in conversation for it to come out, they project it all the time willingly, openly.

Used to use my iPad with PlainText for taking notes; SimpleMind for mind mapping; KeyNote for presentations and of course Chrome for web browsing.

Since I can no longer upgrade the software due to Apple's forced obsolescence, I have relegated the iPad, in a Logitech holder, to being the home automation console and using a Lenovo tablet for business purposes. But for the most part I prefer to use a ChromeBook when not in the office. I find the ChromeBook to be far more practical than the iPad ever was.
