Ask HN: What Aspects of the 2020s Will Evoke Nostalgia?
Each decade has elements that are fondly remembered by those growing up at that time. Over time, that nostalgia can become palpable and thereby create value for businesses who can indulge the nostalgic.

What aspects of the current 2020s do you think will create nostalgia in the coming decades?
> Accelerating absurdly overweight, overpowered cars to anything over 20mph in between stops at lights is just a moral hazard.

The level of absurdity in suggesting a moral element to driving a car at below 30mph just shows how fundamentally biased people have become about a normal part of everyday life. For whatever reason
I sometimes wonder if better management of notifications would improve people's lives.

I don't have any audible notification for email and a range of other things. I'm pretty ruthless about turning off notifications that come with some games and other apps that I just don't care about.

> I realized how our phone has become a real integral part of our bodies.

Counter-example. Having only just recently had the ability to do payments with my phone, I now often go out without my wallet in my pocket. The feeling of not having my wallet made me realise how my wallet was an integral part of my body - so to speak.
Haven't had a mobile phone in years as I value my privacy because a number of online services exist which will geolocate any mobile phone number from anywhere in the world and its a completely legal form of stalking! Besides I noticed I get brain fog if I use a mobile so I need to keep my wits about me as there is alot of organised crime in the world especially those running countries!
That's the fun of thought experiments, the rabbit hole just keeps going.

If your original delete request was followed so that everything they knew about you was deleted, they would not be able to relink everything that GUID linked to. It should be gone now. However, if that hashed value lives in a BANNED_ACCOUNTS table, then all they have to do is create the hash, check the table, disallow new account. You can even do it in good faith by not storing any of the new info rather than storing it and forcing a new delete request.
> Moving ... to a different lifestyle.

When environment is part of the problem, The idea of returning to an unchanged situation seems unlikely to be productive. A couple of thoughts:

Most adolescents need to find a 'peer group' to be part of on the path to independent adulthood. Easy for some; hard for others. I recall a high school student who was having problems and who moved to another ('alternative') school in a different part of the country for a year. There they found a very supportive peer group. When they returned to the original school as a senior, the problems were gone. The school hadn't changed ... their perspective had.

I recall from history that a good many 'notable' historical figures left home in their early teens. They were perhaps one-in-a-hundred who are remembered ... not at all uncommon in the past. Were those times more dangerous? One of my grandparents was 16yo when they left behind family and friends in Europe to sail to the US. Another, 16yo grandparent left rural Canada behind to grow-up in the US. (Both joined friends/relatives.) Are these options legal now? Are we 'trapping' our action-seeking/outsider teens? Is 'therapy' another name for 'my way or the highway'?
I understand exactly what you're talking about. I genuinely can't listen to ideological podcasters who are shitty people. I don't mean ideologies I disagree with, I mean people with no compassion who try to tell you how to live.

Good example: Tim Pool. He's ideologically pretty close to me, but I can't stand him as a person. No thanks.
Just sent two-week notice last week. ~30 applications, 3 offers. I was interviewing with both tech and "non-tech" (software engineer/research role at traditional STEM companies). The stark difference is that for tech companies the track record carries little weight (me with 10+ years dev experience, proprietary and open-source), while in "non-tech" companies the decisions almost solely based on my experience (projects, publications, etc). For the latter all I needed to do is either give a presentation or a round of 1-1s chatting about my work. The tech company interviews gave me an impression of being replaceable: passing these tests then we'll welcome you as a screw of our well-oil machine. What gets me most is that I was still got asked behavior questions like "do you think you are a team player?". (I decided to be snarky on that FANNG interviewer and told her "I like being left alone". I was put off by the fact that she's wearing a mask in our 1-1 zoom meeting anyway).
> If it doesn't it's because it's not enforced. It's irrefutable that vehicles moving at 20mph are less dangerous than vehicles moving at 30mph.

Then make them drive at 1mph
It took me way too long to realize that the author was just having fun with insane ideas, not trying to solve a real problem. Great post:)
What about taking them to court?
Interesting article. The author might want to consider monetizing it with a few ads.
Why should Twitter be the champion of free speech absolutism?

How has that worked out for 4chan and 8chan?
I take it you’ve never had this discussion with someone who has dealt with actual tyrants?

No one who was under their sphere of influence would classify Stalin or Mao as tinpot. They killed nearly 100 million of their own people between the two of them.

Khmer Rouge being a third example.

I’ll take squabbling (but still competing) landlords over ‘great leaps forward’ or holodomor any day of the week.
That was a fun puzzle. I have another one that is math puzzle:

> You are given two eggs, and access to a 100-storey tower. Both eggs are identical. The aim is to find out the highest floor from which an egg will not break when dropped out of a window from that floor. If an egg is dropped and does not break, it is undamaged and can be dropped again. However, once an egg is broken, that’s it for that egg.

> If an egg breaks when dropped from a floor, then it would also have broken from any floor above that. If an egg survives a fall, then it will survive any fall shorter than that.

> The question is: What strategy should you adopt to minimize the number egg drops it takes to find the solution? (And what is the worst case for the number of drops it will take?)

I wrote up a solution for this (along with a generalized analytical solution) on my blog: https://blog.kdheepak.com/the-egg-tower-puzzle
You cannot solve social problems ("how do i know I can trust X") with technology.

meta-code-verify is itself vulnerable to the trust chain. You trust Mozilla/Chrome not to alter the version you install from their store. You trust that GitHub isn't going to pull a swifty on you, or Facebook. You trust that the server hosting the append only log hasn't been unknowingly compromised, or the interpreter, or your machine, etc. ad nauseum.

Indeed, you trust in your computer to display the right hash, and to compare them correctly.

What's more is that this browser extension is useless in the context of this thread, because, as the grandparent post points out:

> A significant % of Twitter usage is through the website (either twitter.com or tweetdeck), which means the decryption would all have to happen in javascript in an effectively untrusted context - it doesn't even have the moderate protections offered by a chrome app/extension, and there's no clean way to securely store encryption keys for a webpage (afaik) without the aid of something like a Yubikey or Windows Hello. Secure cryptography in the browser is still (generally speaking) adjacent to a joke, and the idea of doing it in Twitter.com - a very complex website with a huge attack surface that gets loaded into iframes/popups and targeted by various extensions - is probably exciting to people looking for easy ways to claim Twitter's bug bounties.
It does. The author is doing things wrong on purpose:)
The laugh box! We had one of those and my father in law used to abuse it to make all sorts of creepy laughs for Halloween.

I want one again, now that you mention it. I had almost forgotten about those things.
I'm also curious about an answer. If I may take a guess from my own experience. People from Western countries tend to start meditation practice with a specific goal in mind as opposed to just doing it naturally as it is part of the culture. For me a goal is gaining mental strength and balance. After meditating for a while I reach that goal (at least to some extent) and get overwhelmed by the energetic surplus. That leads to either distraction or simply investing this positivity into another goal (work, a project, social activities, ...) leaving me less motivated to further meditate (because it is less "fun" to sit still and work on your mind instead of doing something). After a while the energetic surplus is consumed and I am sooner or later mentally back to square one - because stopping the meditation also stopped the healing and reflection and I'm faced anew with old wounds destabilizing my mind.
I thought this was about generating a new bank account number for every invoice based on the headline.
> When I was a child, I figured out how my city was shaped, and figured out how to get around.

You either live in a pretty small city, or an exceptionally well-laid one. I have lived in the same city all my life, and while I have a pretty good idea of where major points of interest are, and can probably walk or drive home from anywhere in the city, I definitely don't have any chance of finding a random address someone gave me, or finding a bus&tram route there.
> ... but then people try to overdo it and deal with UTF-8 before having the basic algo working.

Wait... We all know (?) that Java was conceived before Unicode 3.1 came out and somehow thought that 16 bit chars would forever be enough to hold unicode codepoints and hence Java strings are now a mess of both char and codepoint methods but... What's UTF-8 got anything to do with your question, even after a basic algo is working?

If I'm using Java's charAt(...) on both strings, what's the encoding got anything to do with matching if the substring is present? Who cares that one character may have a codepoint encoded using more than one Java char primitive? It's either encoded the same in both strings or it won't match right?

I'm confused.

EDIT: you said it's not fancy, so you're not looking for people to match combining codepoints in one string matching another codepoint in the other string or things like that right?

A bit over 10% (and probably somewhat higher than 10% on HN) of Americans do have something like GDPR. California Consumer Privacy Act. I'm not including Colorado, Virginia, or Utah because I'm not sure how equivalent their laws are.
> you have a job that is just naturally more appealing to men or women?

Unfortunately, I think this no longer appropriate to suggest. I think certain circles would cancel you for suggesting this.
Sample of one: I have many markers of ADHD but do not wish to be diagnosed as such because there are stark warnings about holding certain types of jobs and health insurance increases.

But, being around people does not help me focus at all, I have an anxiety about them interrupting me, maybe I need to pay attention to something going on in the environment because there are people.

Open offices are a nightmare, and I talk about it openly.

Strangely, this issue does not exist in coffee shops. I think it’s something to do with the fact that people are extremely unlikely to interact with me in a coffee shop. So, take that for whatever it’s worth. Body doubling certainly isn’t universal among people with ADHD markers.
The thought of these questions, and engineering more generally, boiling down to intelligent dialog trees hit me like a ton of bricks a few months ago. I've been investing time into deeply thinking about these trees, and it has been one of those things that have made me feel like I've 'leveled up' in my career journey. It's very validating to read your comment, and it makes me feel like I'm on the right track. Aside from plenty of practice, do you have any good reference material or advice to share on improving this skill set?
Neat. I'd love to see what that looks like (raytracer or cradle). Found an old Hack a Day from 2014 (https://hackaday.com/2014/11/25/ray-tracing-on-an-arduino/) where someone is raytracing on a 16Mhz micro. Should be faster on the 120Mhz portal, but it took almost 3 days :P
You seem to be missing the entire point of this kind of question. Yes, you are providing an upper bound. But as you yourself admit, your answer is useless. The point of big o is to put the lowest reasonable bound on an algorithm so they can be compared.

Your approach is basically interview trolling.

I don't use big o in interviews. That's more the domain of big data than the web slots I typically fill. I'm more interested in the depth of understanding they display in the techs they claim to know.
You'd have to do some buffering, but I guess you could "just" (this is way easier with digital tech) buffer scanlines, send the first half of it to one screen, the second have to another at half speed, and replay the line for the next scanline? What's nice is you don't have to buffer a full frame to do this, so there wouldn't be a frame of lag.
There's even a game named after the term where everyone is invisible so you have to look at the other player's screens: https://en.wikipedia.org/wiki/Screencheat
Yeah battery life and fan noise have been so much better on the M1 16” than on the intel 16”, it’s unbelievable.
Depends, they can hide streetlight too which can be disturbing sleep pretty intensely...
To answer a bunch of questions: Yes, I had bloodwork done later showing my D3 level in the typical range. Whether that was due to the supplement, or diet, or lifestyle I can't say. I take 1 pill (USP certified) on average 2-3x per week. So not every day.

I've got treatment resistant depression and have tried probably everything else you're about to suggest. The only thing that kind of helped was dihydrotestosterone, but that is now illegal in the US. Also tianeptine and vorinostat, but also very hard to get in the US these days.
I had not seen that before, thank you for the link.
One missing component (last I heard) to the Obsidian story: there's no web app. With Dendron and others, you can use code-server to use VS Code in a browser. It's a better workflow for ChromeOS, iPad nomads, Wayland users.
Lack of traffic.
Just yesterday I bought stuff on ebay using a VPN (PIA). They locked my account and made me do a password reset.

I suppose good thing I was just buying, not selling anything.
Things can be quantifiably described as "doubled" without that having any real world impact.

In my experience the people supporting these measures are adopting them not because they care about safety at all, but have another agenda.
It is an interesting article.

The "50 sheets" is a bad translation. They mean 50 GPUs.

The person who submitted, coolwulf, is I think the subject of the article. Maybe coolwulf can comment on if this research is now a full time job? Where did the initial funding for 50 GPUs come from?
Is there a readable version of this article?
It's cheating in the same way looking at the community cards is in hold 'em; it's part of the game.
P2P market places already exists, I guess. The tricky part is how parties can trust each other, and I think this might actually be solvable by blockchain / smart contract tech. Basically a smart contract takes the role of the trusted intermediary / escrow account. I believe this is being worked on (e.g. Nexus ASA on the Algorand blockchain).
Awesome!

I wanted to do that forever. Never had the hardware, but being around media people meant I knew it was possible.

Dream come true, in my view!

All that killer analog gear being tossed and this happens.

Now I just want to play, maybe perfect dark too.

To avoid screen cheating, I liked to drop the proximity mines in PD and keep moving. Effective enough they were banned from family play, lol.
I hope that there will be some kind of "authoritarian chic" where people ironically wear masks and say "papers please" and have some vaccine memes as a kind of absurd anachronism for how silly we've all behaved. Maybe some pronoun nametags thrown in.

Realistically, I expect that like a lot of nostalgia, well look back on the freedoms we still had in 2022 and remember a time when life was better.
You don't need a recurrence relation to prove it. You can use a simple algebra where you are able to combine the complexing of algorithms. For example an O(n) algorithm followed by an O(n^2) algorithm will be O(n^2). In an interview I describe how the complexity of these simpler algorithms get combined into my final answer. I assume that the interviewer and I can agree on some basic stuff like looping over an array is O(n), inserting into a heap is O(log(n)), etc.
Title is incorrect - the page says you simply cannot buy new apps. You can still download apps previously paid for, and you can download new free apps.

Yup. Knew those layouts cold. People knew
The separation of powers could be expanded to a far greater extent. In particular the modern bureaucratic state, with its long-term sinecure positions at the highest levels, is entirely antithetical to the whole idea of checks and balances, or "ambition being made to counteract ambition". This is where former aristocracies might provide a better model.

I don't know your situation but I while there are certainly ultra-competitive CS programs (e.g., Stanford, MIT, Berkeley, CMU), there are many research-focused universities in the US (R1) that are totally good-enough for doing research and getting a recognized degree. In a lot of less competitive universities, there is no admission committee per se; you just email the faculty you're interested in and if he wants to recruit you, then it's basically done.

There are good research universities in the R2 list as well (RIT, IIT, etc.)

My understanding is that 10000 lux bulbs are accepted treatment for SAD. I live in a dull country and bought one despite not suffering from SAD. Anecdotally I find it great to help wake up in the dark winter mornings.
> Money must be a unit of measure of a substrate, determined, not owned, by the public, no private parties involved. A symbol we use to weight nearly anything

Maybe you can give me an example or reference? I don't understand what you mean.
The term is "spiritual bypass". You disconnect from emotions, pleasure and pain, etc, see the world as illusion, and no longer feel guilt for poor action.
Huh? So if I change my email and/or password I lose my identity? Flag it in the system to keep a closer eye on it sure, but you're thinking about an edge case that makes the experience exponentially worse for the normal person.
For some reason I was often sick when I lived in Stockholm (Sweden). A friend there mentioned having the same problem.
It seems true without qualification.

What you're saying here has a lot in common with "woo", I hope you realize.

> Don't consider it for [..] whites

Given that something like 6-7 of the 8 Ivy League presidents are Jewish (according to their wikipedia pages), and how underrepresented non-Jewish whites are at the Ivies - why not? Or, let me ask another way: how much fewer non-Jewish whites would the Ivies have to have, before you would consider them disadvantaged (for Ivy attendance)? They are 33% now, so.. maybe when they're just 20%, one in five? Or 10%? Would that be low enough?
Billed as "the hardest logic puzzle in the world". Now I feel less dumb for not solving it myself when it appeared in Cracking the Code Interview.
Yeah, 75% of my team on the current and previous projects are in other parts of the US. We just had a massive reorg to make it more flexible to assign free people to projects around the world.

The CEO and senior VP's have said that we work better when we can see each other in person. At other companies I have really enjoyed brainstorming in a conference room around a white board or solving problems together.

But after this reorg we are going to have even LESS projects together as a local team. My response to my immediate manager was "Sure but then assign people to projects from the same office." It makes no sense to say "come in to work together" and then put us on even MORE remote projects.

A few of the managers also have people working on the project in Israel and India. The managers are constantly on the phone including 7am and 9pm meetings for the foreign offices. I'm glad I don't have to do that but why tell them to come in the office? They are already disrupting their personal lives for the company with those meeting times but it does make sense to make it convenient for the people in India when there are 10 people from India and only one from the US on the call.

I'm glad they are paying us well but the logic of this is idiotic.
There is some truth to what you're saying, but why should one not be rewarded for doing things in less time than it would take in office? Is it not a literal advantage?
I'm sure there's some level of untapped market for average consumers.

$5 a month is a LOT to someone who isn't rich. A few of those services is the difference between being "maybe able to go to a concert a few times a year and still save a bit" or "Literally living on cereal".

Like, look at how much use Amazon Prime and Netflix get. That's the level of service I would expect from something that costs more than a dollar or two.

I do have a VPS that costs $5 a month or so, and a $5 torrent seedbox that I use for some large files on some work projects. But I am actively looking for ways to eliminate that seedbox(I think Google Drive is probably enough).
Mind to provide some recommendation of "serious publications"? Academic journals would be fine as well.

I want to learn more about the politcal theory and relevant social economic grand thinking and mechanisms design.

Which RGB library are you using for esp32? I was doing some initial LED stuff with a Pi with hzellers rpi-rgb-led-matrix library, but I am having to switch over to esp. Also that PCB looks really nice for avoiding the pain with wires. Do you plan on releasing the files for that?
