I can't remember if there's a specific term for it, but I believe HN has some way of giving a story a "second chance", which must have been used here and seems to involve resetting the timestamps.

I don't know if this link will continue working, but if you look at it through this view, the comment that you're replying to shows as "2 days ago": https://news.ycombinator.com/threads?id=oldgradstudent&next=...

But if you link to it directly, it shows as (currently) "4 hours ago": https://news.ycombinator.com/item?id=18223066

I can understand the second-chance idea, but lying about when comments were posted is very strange.

The TSA already gets to harass, molest and assault people all they want. We've had nearly a decade of videos of crazy invasive and disturbing pat-downs of both adults and children. It's pretty obvious if you want to touch people inappropriately and legally, the TSA is the career choice you should be looking at.

I rarely fly anywhere unless I absolutely have to. I've flown a lot outside the country and no other country is anywhere near as bad as the US/TSA. No other country makes you take off your shoes.

I feel like early on, Americans fought hard against TSA security theatre and nothing changed and people kept flying, so it's just stayed pretty much the same.

It's gotten a little better. TSA agent can't harass people as much and have to be nicer since everyone is recording, but everything they do is still worthless. Millimetre wave machines are filled with so many false positives you should just have people roll a six-sided die.
A Funny Thing Happened on the Way to Reimplementing AlphaGo
Congratulations, it's great to see Karmabot going from strength to strength. Keep it up kulesh!
(1) Your group number 2 describes a sizeable portion of law school graduates who actually do end up in six-figure corporate jobs, as well as a decent (though smaller) portion of medical school students. Unless, only those persons who obtain the six-figure jobs out of graduate school are academically gifted. This would mean, however, that sizeable portions of the graduating classes of many such schools (even just the elite ones) harbor non-academically-gifted students. That's not an indefensible position. However, it would be rather odd and not terribly convincing on its face, as presumably only the academically gifted could have arrived there in the first place.

(2) Even assuming your argument goes through successfully, it is irrelevant to whether the person committed the sunk cost fallacy, which is the issue under discussion. Now, you could argue that subjective assessments of expected value always track the true underlying expected value (i.e. the actual expected value for any individual's objective abilities). In that case, all non-academically-gifted students who chose further education would likely be committing the sunk cost fallacy. That's not the case though, and you know that. Or you should, because it is prima facie absurd.

(3) It is relatively uncontroversial that there is a substantive disconnect between the supply of graduates and the number of jobs paying a salary justifiably commensurate with the debt-levels we are seeing. This has a couple of knock-on effects. For example, an across the board devaluing of degrees, which unjustifiably increases hiring requirements for lucrative professional jobs, further exacerbating prestige whoring, etc. This turns high school seniors deciding to attend elite private schools into even greater gamblers as the cost of an initial degree rises. Maybe they are or maybe they aren't rational to take that gamble (Are gambles by definition irrational? If so, pick a different term.). However, after having taken that gamble and come up short, they don't automatically become irrational in taking it again. Or, at least, the irrationality wouldn't necessarily have anything to do with the sunk cost fallacy.
The criteria for adaptive evolution, in the classical Darwinian sense, are:

1). Reproduction.
2). Variation between the products of reproduction.
3). Heritability between those variants.
4). Differential success among the variants.

Anything that has those four characteristics will experience adaptive evolution. Where it gets really fascinating is when you realize it applies to things that don't go through biological reproduction, for example the graphical user interface.
Anecdata: my piano teacher was one of a class in the 1920s who were all explicitly trained into absolute pitch during kindergarten . Every person in the class learned it and retained it until at least late middle age. Some were better than others: my teacher’s sister, for example, could give you the pitch of anything from knocking a piece of wood to the sound of a car exhaust.
Hey wow! Site author here, tons more solutions on Github than I've posted on the site: https://github.com/wholepixel/solving-sol

> Air travel is not a right guaranteed by the constitution. TSA gets a lot of leeway because of this.

Travel in general is protected, and in addition the 9th Amendment clearly states:

It seems Beyerle (our university IT guy) was able to acquire a local license for a seemingly fair $12k after getting a discount from the FCC no less.

"About 20 years ago, Beyerle was the winning bidder for one of 14 licenses in a high frequency band for his local area, paying just under $12,000 (after getting a 35% discount that the Federal Communications offered to smaller bidders)."
That sounds like a tiny horror story to me. Losing my hearing would be much more difficult to me than losing my site. My sympathies are definitely with you
This is completely unrelated to the fact that a single engineer was able to override the software to take the car for what is effectively a joy ride.

This should never have been possible to happen.

The fact that Waymo hushed this up also doesn't instill trust.

Good! I for one am glad for this and the measures that were implemented as a result of certain actors wishing ill on our society. It’s a small price to pay for piece of mind when flying. For the past 17 years there was immense fear-mongering of what kind of slippery slope these measures would lead to and yet none have really materialized.

> Previous studies have found that dandelion seeds always have between 90 and 110 bristles, says Nakayama

Those poor research assistants. Imagine counting hundreds of dandelion bristles every day. Probably still not possible with AI/image recognition either.
The problem with commercial offerings is that at larger scales, there often needs to be special optimizations for large scales, which don't apply to most customers of that vendor.

For example, imagine that System X can scale well up to 1 terabyte of data, but that after that it becomes increasingly complex to handle more data and it requires special optimizations to maintain an acceptable level of performance.

From System X's perspective as a vendor, 99% of their customers are perfectly fine with the performance of System X and just want more features (that the vendor can charge for upgrading to the next version of System X). On the other side, there's that annoying 1% of customers just keeps on asking for more and more performance optimizations that 99% of their customers don't care about.

From the vendors' perspective, it makes more sense to invest development efforts into features (that can translate into more money) than in performance optimizations that only appeal to a narrow segment of their users. For the company that requires these optimizations, since the commercial codebase is proprietary, they're locked in and have no easy way out.

That's pretty much why the large tech companies invest in owning their own part of the stack. It mitigates a scaling risk, keeps expertise in house and ensures that the solution that is developed in house matches 100% with the often specialized needs of the business.
A) math refresher: Basic Training in Mathematics - Shankar

Last one sounds pretentious but was a magnum opus. His postulates concerning consciousness as a synthesis of quantum functioning were probably a bit much.

FWIW when studying Japanese back in 2002 I liked the Heisig method but wanted animated stroke order displays for the characters. Jim Breen at Monash in Australia had half the set in .gif but I had to coax Jack Halpern in Japan to release the other half. Armed with the full set I was finally able to digitize the Remembering the Kanji in a useful .html form for personal use over the space of a month (still keep it as a bookmarked local app in Firefox). When done, apps like Anki (tr: memorization) J-flashcards started showing up, duplicating the work. :)
No fly lists are inherently unconstitutional. They are secret lists that limit travel. They are applied arbitrarily with no judicial process. They have existed since 9/11 and they need to be banned.

But yet... the electorate still believes in the safety they create because no legislator that I’m aware of has even broached the topic. I hope to see candidates with some sane opinions on this soon.
I'm very conflicted about this. And I'm actually sitting at my gate while typing this, in an uncharacteristically busy terminal, where I'm suddenly so very urgently aware about the risks of large crowds at airports and such. Conflicted because it does make sense to me that tracking people in facilities like this could help with safety and security. I have no principled problem with my picture being taken. But I wouldn't want it to be abused, for sure. So... is it the secondary uses, like marketing and totalitarian uses (never thought that'd go in one sentence) that I'm worried about? Or should I be worried about it anyway? Does the distinction matter? Is distinguishing between the two possible? Realistic? ... CONFUSED!
I can work 4 hours in the morning...very productive. I come back from lunch and work 2 more--usually dealing with politics and mentoring. Done.
I’d argue that you are either at synesthetic or are somewhat pre-disposed to absolute pitch. I have heard others describe it the way you do but I do not hear tones that way.
Ask HN: Why do undergraduates in physics/math want to work in academia?
I recently had a conversation with some undergraduates in a physics program; what they told me is quite telling. Some of them work 40-60 hours per week on classes, often more than five per semester, and are very obviously burnt out.

When asked what they would do if given a job offer from AMD, Intel, or some other company for a fulltime position with a salary around $60-80k/year, they remarked that they couldn't possibly take those jobs because they'd be "soul-crushing." They pointed out that graduate students in the sciences earn a median of $25k per year, and professors can make even more.

My question is this: how can one rationalize spending 4-6 years and $100-300K in tuition merely to spend 3-5 years on a PhD while making little more than $100k over the entire degree, rather than taking a job offer that could wipe out their student loans in 2-5 years?

Is it simply that the students most optimistic about grad school are the most likely to receive high-paying or high-quality degrees or professorships?

Automation has eliminated a ton of jobs.

Look at the steel mills of the early 20th century. They had groups of people hoisting around huge pieces of steel on chains.

Look at a modern steel mills. All that hoisting is now done by heavy machinery control by one guy in an air conditioned operator cabin.

By offshoring or just the advancement of technology, those jobs are gone.

I agree but you can't realistically build policy around "working to be better humans". Walls, guns, surveillance, etc are all easily deployable policies with easily measurable results. I don't enjoy the surveillance state or waiting 2 hours for airport security but it is tolerable...to an extent.
If air travel is the only feasible way to leave the country, then yes, it is guaranteed by the Constitution.
That's the central argument right there. We just need people to refuse to use air travel based on this if it comes to pass - I know I will.
These flaws are likely intentional. In a global marketplace, the current regimes in power are the ones making the purchasing decisions of what machines to use to run the next election.

Machines that can be readily tampered with and reprogrammed in undetectable ways likely sell better under the assumption leaders would rather stay in power and have ceremonious democracy than risk being ousted or overthrown.

Regardless, if someone was upstanding and wanted to run a fair election with the machines, they can do that as well. Ones that can be altered, preferably only by the election committee to change an election without getting caught, is likely a highly sought after device.

That's likely why we keep finding them over and over again. Every few months another trivial exploit that a fairly incompetent people could discover is found on yet another device.

No receipts, audits, paper trail or any verification ... just a bunch of readily reprogrammable devices that anyone with a USB stick or an sd card or the edge of a housekey could use to change the votes however they please. Again and again and again.

It's very likely intentional.

Pair programming: when u need 2 devs to do 1 devs job
In general if you are suppressing a class of people’s participation, the top people in that class will be more apt than your average participant. So including them will increase the average aptitude.

The only time that isn’t true is when you are suppressing a class of people who are fundamentally shittier than the dominant class.

The affirmative action debate comes down to whether you think skewed performance numbers are evidence that a) some of the classes are superior to the others or b) the numbers don’t accurately measure performance.

There’s nothing inherent in the data to point one way or the other. It’s just a litmus test on whether you’re a supremacist.

> Ends do not justify the means.

So was Egypt better under the Muslim Brotherhood than the military junta? The "means" of their overthrow were certainly bad (a military coup), so does that automatically mean it would have been better for Egypt to have continued to be ruled by the Muslim Brotherhood. Is Singapore a morally bad country? We don't know for sure if they would have achieved the same results with a democracy, but in our mental image of "shitty, immoral countires" does Singapore pop into mind?

It's easy to make moralistic claims like this, but to a certain extent we all agree that certain ends to justify certain means. Police shouldn't kill a criminal for stealing an orange. But they probably should kill a criminal if they're holding someone hostage at knifepoint (Purely speaking in terms of the morality of killing people in commission of a crime, I don't know if shooting at a someone holding a hostage is good policing)

Design Decisions in the Forth Kernel (1993)
I could not disagree more. Trading liberty for safety is not something we should ever do. Risk mitigation is different than giving up rights. They can be done at the same time without compromising anything. “No slippery slope...yet” isn’t really a thing you want to rely on.

I am personally furious every time I fly because these rules do little to protect us. I’m glad it is giving someone (you?) some peace I guess, but the cost is too much to bear.

Outside of rights, do you have any idea how much this costs taxpayers and how insanely run that organization is? I’d say it fails many, many rational tests.

>One advice we can't act upon is "work less". We can't win.

I think most of the people on hn (or at least most well-paid tech workers... do those still make the majority here?) can work less fairly easily, if that working less comes with the massive performance boost that goes with sleeping properly. I'm sure it's way different for retail and other hourly-type workers.

If I sleep more and if I sleep better? I am just way more effective. When I'm being effective and getting things done, people are pretty slack about me showing up late and/or leaving early, even at the FANG companies.

I mean, I don't know anyone who put "I worked X hours a day" in their promo packet; nobody cares. no, the idea behind the promo packet is that you show what you accomplished, and how those accomplishments effected the company.

My experience is that the boss gets on me about working more only when I'm not producing enough; usually the solution isn't to work more, but instead to figure out why I'm not performing up to expectations and fix that.
Candidate story for “Last week tonight”.. wow terrible..
The neutrinos may start out with any energy, whatever produced them will determine that. To cross the great expanse of time and redshifting due to expansion and still have a lot of energy left, they would simply have to start out with a whole lot more. Any neutrino event that we could detect from that far away would probably be massive anyways, so maybe we'll see something.
It is now clear Khashoggi was assassinated. Only in an authoritarian system, can dissent be permanently disabled by killing a human. In a democratic society, there is a well-defined process to determine the outcome of any event, including dissent.

This makes sense in theory but in practice I have observed that commercial data warehouses are incredibly well optimized. There are lots of companies we don’t hear about using Snowflake and BigQuery to analyze giant datasets. They don’t blog about it because they’re just using boring commercial tech. I think the real reason companies like Uber build their own stack is just good old not-invented-here.
