It's not settled science but there's decent evidence that the padding and helmets contribute to the more violent nature of American football (where serious and long term injuries are more common than in rugby).
> Meanwhile, pretty much anybody whose field has been touched by Gladwell reports that his account of their field is utterly uninformed, lacking nuance, and shaped to reach a foregone conclusion.

“Briefly stated, the Gell-Mann Amnesia effect is as follows. You open the newspaper to an article on some subject you know well. In Murray's case, physics. In mine, show business. You read the article and see the journalist has absolutely no understanding of either the facts or the issues. Often, the article is so wrong it actually presents the story backward—reversing cause and effect. I call these the "wet streets cause rain" stories. Paper's full of them.
In any case, you read with exasperation or amusement the multiple errors in a story, and then turn the page to national or international affairs, and read as if the rest of the newspaper was somehow more accurate about Palestine than the baloney you just read. You turn the page, and forget what you know.”

Top Lessons Learned While Building My First SaaS at 18
Holy crap...I'm pretty sure that the Marcus Bannon mentioned is someone I went to high school with.

What an utterly bizarre, and shrinking universe.
I don't know who GP might have had in mind, if any specifics, but what comes immediately to my mind at least is the whole-lotta-smoke that seems to come from the general vicinity of Congress (e.g. https://en.wikipedia.org/wiki/2020_congressional_insider_tra...).
People frequently have this misconception that they are competing with their peers. You are competing with people that could have been hired instead of you - not your peers.

And on that front you are diligent and will eventually reach performance, so everyone should be happy with you.

I am a little concerned that you have three different tickets assigned to you. Are you held up on the first two tickets and so need a third one assigned? If you are just working on all three at once then the context switching is bad for you.

If you are held up on the first two tickets does anyone know that? Do you have a way of communicating that you are held up on those tickets and what you need answered?
>Note that this high level insight isn't really a contribution of the paper

The problem with this statement is that nobody outside of the design staff understood how the algorithm was weak, or (AFAIK) precisely what the criteria for "weak" actually were. Moreover -- after the export standards were relaxed and GEA-2 had shipped, nobody came forward and said "remove this now totally obsolete algorithm from your standards because we weakened it in this way and it only has 40-bit security" which is why it is present in phones as recent as the iPhone 8 (2018) and potentially may be vulnerable to downgrade attacks.

There are some stupid ways to weaken a cipher that would make it obvious that something was weak in the design, e.g., just truncating the key to 40 bits (as IBM did with DES from 64->56 bits, by reducing the key size and adding parity bits.) The designers didn't do this. They instead chose a means of doing this that could only be detected using a fairly sophisticated constraint solver which (may not have been) so easily available at the time. So I don't entirely agree with this assessment.
Not quite sure what you're after but you can get a Voyage 200 graphing calculator for not much more than a RasPi now - it's got a Motorola 68000, a qwerty keyboard, a sunlight-readable screen, a serial jack, a useful OS with many games, a C IDE, a disassembler (both onboard!)... and it runs on 4 alkaline batteries.
Is denormalization (e.g. to star/snowflake schemas) still common or advisable? I know the conventional wisdom is that it can improve performance, but how much scale does it actually get you in practice (a factor of 2? an order of magnitude?), and can it still be the right call for public cloud based workloads where it's trivial to scale vertically and relatively easy to scale horizontally?
Thanks! I had a closed look at them and the naming is starting to make sense: Q=quad, D=double, S=single, H=half, B=byte (except the article claims that V=128bit and there's no mention of H or B)

For general purpose registers: X=long (64-bit), W=word (32-bit)
It sounds pretty malevolent to me.

But I'm disinclined to attribute malevolence to people without a motive. So I'm inclined to think they had to implement an API for some contractual reason; they put their best architect on it, with a brief to minimise server load at all costs; he then handed it off to the most junior developer team.

BTW: API implementors don't generally design their API around the unit-testing requirements of the API's users. Please don't test the API I wrote; I've already tested it. Test your own code.
> We have use what works with the evidence we have because there isn't a better solution for people who need help now

Except in the case of the article, where there is an alternative that shows promise to a better solution, but struggles to find funding or legitimacy, where the reason it struggles to find legitimacy is because of "lack of data", where the data can't be created because of "lack of funding" justified by "lack of legitimacy".

So one of my criticism is in the priorities.

My second criticism is in the lack of acknowledgement of how primitive our mental health understanding and treatments are. I feel there should be more humility there. Yes a psychiatrist has studied hard for many years, but after those many years of studies, they should still be able to say, even after all this hard work studying, I cannot tell you what you have, why you have it, and how to fix it, but I can help you through a process of trying various drugs that have various effects to hopefully find a mixture that helps you cope with your disease.

And I understand that doctors are wary of other people selling snake oil, someone else saying well I know what you have and can cure it, and then go in to explain things with made up stuff and provide unproven treatments. But at the same time, the humility should create a curiousity around all such claims, what if they are on to something, after all, we know that we don't know, what can we do to know more? Especially when such claims are made by medical researcher in the fields like in this article.
I've been doing web development since the late 1990s. I don't know every fiddly detail of every current web technology, but I can pretty much pick up any of them, read the docs for an hour, and have them going in just a bit more time, because I've got a solid foundation from working on things back when even XMLHTTPRequest was but a fever dream.

I was recently speaking online to someone trying to get into it from a fresh start, and they lent me their perspective (kinda like a rubber duck debugging session), and I was a bit appalled at how hard it is to get into web development at this level now. I ended up recommending an approach in which one recapitulates the browser's development cycle if you want to really understand what's going on out there... it isn't the best choice technically in the short term because it's a long path to tread just to do "this one thing", but if you want to be similarly flexible and know how to work with the mess of technologies out there, for path-dependent and historically-contingent reasons (that is, opposed to any other good reasons), I think it may still be the best way to go.

And to be honest, there's still a lot you can do with server-side generated HTML, the tags in modern HTML, and a bit of pure Javascript. There are good reasons to move beyond that; I don't mean that in a "back in my day" sort of way. But if you do start there, the rest of the stack makes a lot more sense than trying to start directly with React as your first intro to the web, as fine as React may be.
It really doesn't and who cares. The source of this article is from the BBC and they and every clickbait tabloid media company does it all the time.

What really matters is if she and her assistants can do anything about the Big Tech problem or not. Otherwise it's a huge waste of time and nothing happens.

Economists: Was "Amazon’s Antitrust Paradox" really as big of a deal as the reporting says?

As someone who doesn't know much about economics, I never assumed that a monopoly would be merely defined as a cost-based analysis of corporate products. I assumed basically what the paper was arguing was how the system worked - you can be a monopoly even while providing the lowest cost to consumers.
Toxic culture of education: Joshua Katz
Interacting between the crypto space and the U.S. financial system is hard. USDC does it by being a well-regulated in the U.S. and internationally financial institution, but that's certainly not easy.

Just one example (from [1]):

> At the time, Bitfinex (theoretically a Hong Kong entity but whose location, like a Bond villain, changes moment-to-moment to fit the needs of the scene) was banking in Taiwan at Hwaitai Commercial Bank, KGI Bank, First Commercial Bank, and Taishin Bank.

> Taiwanese banks do not have direct access to the U.S. financial system; they engage via correspondent banking relationships. These banks corresponded through Wells Fargo. Wells, in the wake of publicity about the Bitfinex hack, told the banks they would no longer clear USD wires to or from Bitfinex.

OpenShift isn't a legacy system, it's a commercially supported distribution of Kubernetes. That's about as close to "new hotness" as you're going to find in government.

Unless you mean they're stuck on a version from 5+ years ago, which is believable, but hardly OpenShift's fault.
I don't disagree with you, but might provocatively suggest that federal funding in the US vis-a-vis a large university could also be considered a large corporate interest at this point.

Eyes on the street used to be provided not only by stay-at-home parents, but by other folks going about their lives: people walking through, shopkeepers, etc. Over time, modern suburbanism became more and more locked in: extreme separation of uses, strikingly non-through streets, non-street-interacting access to apartments, houses, and shops, lower density, etc. This isn't the only story, but it's certainly a part of it.

Clearly the freedom to choose is the actual problem here. No one here is taking time to point out issues in bitcoin that would fail to laugh at someone loosing their money as a result, let's be honest about that at least. Thus it's pretty clear that all of this a double standard to crypto, and are only feigning concern for it's users.

The real issue here is the collective concern about crypto's impact on an already failing USD. These people are just trying to selfishly protect their own investments by utilizing the legal system like a bully. Hey, this sounds like a problem crypto might solve...

Show HN: iOS app that blocks opening other apps until you write purpose (Beta)
Hi there!

I would like to share my side project.

I work on iOS app that helps to use our devices more mindfully.

There is a huge update coming and it is available now!
TestFlight -> https://testflight.apple.com/join/feQ9YDI0.

App use Apple's Shortcuts automation to "lock" selected apps on which you want to spend less time. You can unlock selected apps for a limited period by adding usage intention to the app.

Additionally, the app has an iOS 14 Widget that reminds add intention right on the home screen, keywords daily limits, additional intention check like "captcha"(to check that you do not open apps on autopilot).

I would be thankful for trying app and sharing your thoughts.
Well yes, absolutely. I phrased that poorly, what I meant was like '/bin/sh is better... Especially if it actually works' or something.

It's easily done though, I've often thought I've written something POSIX compatible and then had shellcheck say nope.
The hard part is "all Federal agencies".

But let's not pretend that historians influence the policy makers as much as sociologists and economists do either.

The damages when they are wrong are orders of magnitude bigger.

They are assumed to be right, sometimes even without proof, until they are tragically proven wrong.

And nobody lose their job anyway.

Have you ever seen a sociologist lose the job because proposed something to a politician that resulted in lots of people having their life ruined?

I never did, honestly.

Have the last three more recent economic and social crisis been caused by historians mistakes?

"I'm having this issue a bit with my wife. I want my 9-yr old daughter to go to the playground a couple blocks away on her own; my wife is reluctant."

...

"We're planning to compromise by letting her do it, but only after we get her her first phone."

I hesitate to enter into child rearing discussions but ...

May I suggest a slightly different approach: satisfy your wife by following, secretly, your child at a distance the first few times. All the benefits of independence and self-reliance, etc., for your child - and a gradual, baby steps approach for your wife as she gets comfortable with this routine.

May I also suggest that a phone is unnecessary due to the fact that every single other person already has a phone. Further, bad actors will likely assume your daughter has a phone. It's classically selfish behavior but you can piggyback on the (telephone) safety net that everyone else has already constructed. I know from voluminous personal experience that everyone, everywhere, is happy to use their phone to help your child. Just make sure she memorizes your phone numbers :)
I don't think that, no. Still, different people with different toolboxes will come up with different solutions.
I never thought about this much but now and it has been so since Forth anyway: why are definitions prefix? Why do they not gobble up the stack? I always found it easier to create everything uniform like [0]. And I did that for many years with asm and c as well because I thought it was faster than porting something (it probably was not but he).

I just like to minimize exceptions to rules and this seems a weird one to me. But probably has reasons I am unaware of (besides subjective readability which is, of course a very good reason).

In light of the AP's new policy on minor crime reporting, I was curious how they would treat this story. Unfortunately, their website has no coverage. However, they did report today on another (alleged) insider trading case, and they use names liberally.

A lot of these standards are generally created by industry consortia, and participation in standards setting is limited to companies who are members.

This isn't the IETF where any rando can join a mailing list and chime in on a proposed standard/draft.

IEEE (Ethernet) is somewhere in the middle: you have to be an individual member (though may have a corporate affiliation), and make certain time/attendance commitments, but otherwise you can vote on drafts (and many mailing lists seem to have open archives):

> your main worry by a country mile should be cars, not predators

100%, and cars are a reasonable worry that we should do something about. There are well known traffic calming measures that we know slow down traffic substantially (speed being one of the greatest causes of pedestrian fatalities) and even in my very walkable city we're largely not using them.
Wasn't the informal natural of 19th and early 20th century Italy politics one of the factors that gave rise to Mussolini?

I mean this is more vague memories from school which probably oversimplified factors. I just remember it mentioned that 'political parties' were more informal groupings around outsized personalities leading to clientalism and cronyism.

I don't understand how someone so young is made responsible for such things. They'll have possibly never even managed 5 people, let alone large organizations. She's a Associate Law prof barely out of school.

If they are 'brilliant' - that's great - then the should be senior advisors to the Head of the Commission, not Head of the Commission.

We don't want theoretical ideologues in those kinds of positions.

We ended up with companies like Facebook partly because we put 'really young people in enormous positions of power'.

These kinds of jobs is also as much about politics, people, relationships and 'knowing the system' as they are 'being brilliant'.

At my age, I'm keenly aware at how I was not ready for a whole bunch of things 10 years ago. Experience is real, just just 'an age'.

Edit: responding to the commentor below, yes thanks I should have added, at age 32 you're not tangled up in a web of politics. Also what's hard to describe is that the wager and risk becomes much great as you go on. At 32, you have your life ahead of you, you can burn political capital. At 50, you have to absolutely be making sure you're either 1) keeping your job a long time or 2) making a major transition, enabled by doing favours, political things etc. - you have your retirement, a spouse and 3 kids all going to Uni to worry about. That mental state is an advantage. But again, the skills you start to gain after age 32 matter a lot and that someone who's brilliant like this is much better able to help as a senior adviser to someone with the organizational political skills.

It very much was but not at the relative income level most of HN is at or was raised in so people forget about it.

> As a manager it seems to me that WFH externalises one of the most expensive costs to employees: office space.

I would agree on principle but there is a circularity here. The cost of own housing used as office space is directly related to how expensive the housing was. In Bay Area the marginal cost of a 3rd bedroom could be $XXXk while anywhere else it can easily an order of magnitude less. Then it is not necessarily as the most expensive item anymore.

The more office time employers demand, the more spatially concentrated the work force is going to be housed, which will increase the cost of that extra bedroom.

Turns out concentrating the work force is also aligned with the sunken real estate investments those BigCorps had undertaken. You can bet as we look higher in the corporate hierarchy, the likelihood of personal real estate investments increase too. So it is a balancing act of those influences vs. the projected attrition rate of the workforce, who mostly did actually like WFH. That's how we landed on the unstable-as-hell equilibrium of hybrid WFH-WFO for now.
My comment was on older-self vs younger-self.

It's not in your "self-interest", the way you mean it, to review your ideas and believes from when you were younger and realize that with your extra experience you see things differently now.

And just to be 100% clear, I am all for having younger people in critical positions and don't try to argue that one is better than the other.

My reply was on how age matters. Don't know why you try to twist it to a generational flame-war.
> it provides more positive aspects than negative ones.

I mean, the negative aspects are pretty significant with the whole climate change and mass extinction going on. To make up for that we get cat videos and iPhones?
I often think about the old parable about a man walking down a road that comes to a fence. There is another man on the other side. He asks him to open the gate, and the man replies, "I'll open the gate if you can tell me why the fence is here".
But "Mein Kampf" is an important primary source propaganda, whereas Gladwell's books are trash secondary sources, unless the object of research is "comforting false narratives of the early 21st century".

I don't think that's fair to "Mein Kampf" (!).
That's exactly my point. They didn't in the past, but modern OS vendors do.
I think the source for that comes from the book referenced in the article, which was written in the 1800s. That books has a reputation for exaggeration.

For example, it is the book that popularize the idea of the “Dutch Tulip Mania” causing mayhem, when it was in fact much smaller scale / not a big deal (my understanding) based on recent research
The first couple of seasons of Revisionist History were podcast gold. Lately though? I only listen if I'm desperate for content. It has taken a massive nosedive.
honestly I hear this a lot - why does it matter? do you think the government isn't working on those other things as well?

misdirection must be the most effective strategy of all time. in an alternate universe this would be "Lina Khan: The 32-year-old taking on ISPs" and there would be an identical comment to yours lamenting why Big Tech isn't being investigated
It has been explicitly trumpeted widely. The admin itself has highlighted it.

I majored in psychology in undergrad. A big part of why I didn't look for a psychology focused job is that the science is all so loose. I'd often learn about two different study-backed phenomena is two different classes that somewhat contradicted each other. Or I'd learn in a subsequent class that a previously taught study has been invalidated in one way or another. Almost everything is measured subjectively, so huge parts of our knowledge of psychology are a house of cards resting on assumptions that the diagnostic questionnaires used to measure are accurate and reliable. Many of the measured effects are small, and so it's hard to trust that randomization and controls are sufficient. Replication of results is a major issue.

It all just feels so 'loose' compared to the physical sciences.
One has the advantage of having been in both situations.
