I guess this is more of a "do you know about database indexes" question, but I think if it less of a gotcha and more of a jumping off point into a discussion you can take it in a number of directions:

- time vs. space tradeoffs

- insert vs. select tradeoffs

- Oh yeah they're binary trees also, with those implications

- What's reasonably distributable (downsides of UUIDs)

- at what point might you have query performance issues you can address w/ indexes

But like, again practically speaking I think this is just an experience test question. I think I'd prefer something like "on your resume you have Postgres experience dating back 7 years, tell me what you think about it, what its strengths and weaknesses are, and why you would or wouldn't use it".

---

Maybe you have thoughts about this too, but I'm also starting to develop some thoughts around whether to consider interviews quizzes/tests or conversations. Thinking about it, I've always approached my interviews (on both sides of the table) as conversations--even questions with simple answers. I guess that's why my answer here is "this should be a discussion about databases" and less "table scans vs. index scans in 30 seconds go". It's totally OK to drill down into specifics and be technical, but this is potentially your first interaction with a new colleague, and you should be collegial, not domineering and inscrutable right? I think we get so worried about hiring a faker that we justify anything to avoid it.
Agree with all of the above. Currently in a stable job and 6 months and counting into my job search.

Absolute desire to leave but not for some rubbish compromise out of desperation. It can be frustrating but I believe it will be worthwhile to get the right role. And, importantly, I'm in no despeate rush.
When the party storing the DM controls key storage/exchange, does this matter? If you can't verify the other party's keys are in use, and ensure no other keys are being silently added, this type of encryption is just checking a box.

> Afaik unhealthy diet increases gluten sensitivity

I don't want to argue with your overall point at all, because I assume that whatever this sentence specifically means to you is true for you - but given that there is no actually objective definition of what a healthy diet is - it's hard to agree with the statement in general. I would feel like I was eating unhealthily if I had a can of coke every day, but that doesn't actually mean it's unhealthy. It probably depends on everything else I'm eating, how much I'm burning off, maybe even something as fine-grained as how fast I drink it. You would almost definitely feel unhealthy if you were eating bread every day, but as long as it was whole-wheat and had some good sandwich fixins in it, I'd feel pretty good about that.

Anyway, sorry if I'm being pedantic, but I feel like people toss around things like "healthy diet" as if we're all supposed to know and agree what that means.

I think the ad-hoc selling on the internet thing is kinda done, outside maybe craigslist-like things. But selling obscure things often requires a bigger than local market, where you need the full US or similar size to get a sale at a price that is worth the trouble. If there is at least $10 or $20 profit I could entice a kid to do the legwork. Have a job, so mostly doing it to save things from ending up in landfills.

I've had ebay and amazon accounts for 20+ years. Was happy with selling used books on amazon for example, but for several years can't sell any longer until they can pierce the rest of my privacy. Sucks because I had a highly rated history.

Maybe I should log in to ebay again and see if it is still possible to sell there, but this message fills me with zero confidence.
As I teacher, types.SimpleNamespace is wonderful for helping people bridge between their understanding of dicts (a fundamental) to classes/instances (a little less fundamental).

However, I almost never use SimpleNamespace in real code. Dicts offer extra capabilities: get, pop, popitem, clear, copy, keys, values, items). Classes/instances offer extra capabilities: unique and shared keys in distinct namespaces, instances knowing their own type, and an elegant transformation of method calls ``a.m(b, c)`` --> ``type(a).m(a, b, c)``. Dataclasses and named tuples have their advantages as well. In practice, it is almost never that case that SimpleNamespace beats one of the alternatives.

I basically agree.

"Selfish" is a sloppy word that combines unlike things. Which means it's a toxic word.

People should be self-interested. We are organisms, after all. Like animals.

However, people should not be fixated on their own self-interest to the point that they neglect the bigger picture. If you neglect the bigger picture, you will not be successful at being self-interested.

For example, if you neglect your spouse's feelings, people will say you're being "selfish." But you aren't being self-interested, because you aren't promoting a good life for yourself.

For a good critique of altruism, which is really a separate topic, see Ayn Rand.
>The reason for this is because I'm not hiring for the craft of software engineering, which your perspective aligns with, I'm hiring to achieve business objectives quickly, efficiently and to a high standard. Not realizing that most hiring businesses are optimizing for the latter and not the former is what trips a lot of career software engineers up. You see yourself as a craftsperson, the employer sees you as a resource to achieve their business objectives.

You put it in an interesting way. But FAANGs and big tech are businesses, too. They would want to achieve their business objectives, too. Still they hire someone who is not proficient in a particular language / framework if he is a good developer. Maybe the time it takes for them new hire to ramp up is worth.
Probably none, if they were never used. Again supporting the idea that they are better at creating a feeling of security than actually making any difference.
I recall a time, many years ago, when you could be at a pub with a couple of friends and some really obscure question like whether it's a duck who has a corkscrew willie or a woodchuck, and nobody would know the answer and there was no way to find out, barring going down to the threadbare and underfunded local library to look it up in the encyclopedia, which itself was terse on facts and probably omitted ones like that for morality's sake. Now I could just whip out the black mirror and Google it.

> I believe the latest IPCC report on climate change expected outcome even for the worst scenario had a noticeable decrease in the rate of growth of the global economy - not a contraction, just slower growth. We do not seem to be on track for a global contraction of economy, not even in the face of climate change.

The reports do talk about economic contraction after the year 2050 if we don't reach the 2 C temperature goals. They also don't model the likely resource wars that will happen if large parts of Bangladesh, India, Pakistan, Mexico etc will become uninhabitable by the end of the century, due to rising temperatures and water levels.

> And economic growth is already (though not that recently) somewhat decoupled from growth in greenhouse gas emission, so any actions taken to reduce climate consequences do not have to be at the cost of stopping global growth, much less intentionally contracting global economy

The IPCC reports says that GHG emissions increase is mostly proportional to GDP increase throughout all regions, with a significant, though smaller, contribution from population increase. It's also notable that GHG emissions continue to increase - we are not anywhere near a plan for net 0, and nothing suggests so far that we are even likely to start reducing GHG emissions, globally or even in any particular region.
The headline gave me the same initial thought. I assume the experiment controlled for this, but so much of the mindfulness stuff is associated with self-optimizing hustle culture types that it seemed obvious to me it would correlate with higher-than-baseline selfish behavior.

My issue with this specific concept is that lots and lots of people are lazy and instead of doing compassionate things, they "feel compassion" as a generic emotion through the use of meditation.

I studied Buddhism quite a while pretty seriously, and I know that a lot of the meditations involve practicing loving yourself, and your friends, family, community, and that these feelings of love are a core thing to have in your mind as your practice. But you also have to actually do things to help, it's not enough to be nice about it.

The Buddhist temple I took some meditation classes at practiced feeling good things towards people. The Episcopalians next door ran a shelter. It's not hard to see which is further on the path towards enlightenment, and it's something that seems like it's very very often missing from Western teachings.

And completely absent from self-help books about the subject, which are 100% self-centered. Lesson 1 of compassion meditation should be volunteering at a food bank, not learning to forgive yourself for your flaws. These things should be learned together, not in isolation.
It did use one time pads:

Two paper tape readers are mounted in front of the 700 Unit at the top. One is a 5-level tape reader, which is used to read the plaintext (when used offline). The other one is a 6-level reader which is used to read the keystream tape. The signals of both readers are 'mixed' in the 804 unit by means of modulo-2 addition (XOR).

…

For proper security it is important that the keystream tape contains a sequence of evenly spread truely random characters. Producing such a random keystream was a major challenge during WWII.

When the need for keystream tapes increased during the course of war, the manual production was replaced by electromechanical methods. The machine that was used for the production of Rockex key tapes was codenamed DONALD DUCK, possibly because it speaks gibberish [3]. It wasn't before the application of a noise source however, that truely random key streams were produced. In the UK, a noise generator with five flip-flops was developed at GCHQ just after WWII by former GPO-engineer Don Horwood, who had also worked on Colossus at Bletchley Park.

…

Furthermore, he allowed only two identical tapes and instructed them to be both destroyed immediately after use. This way the machine became a real One-Time Pad system.

You're spot on in mathematics and CS on this. But the important take-away to me is that there is no way to express disapproval in the current western democratic voting system. Even non-voting is not disapproval. I'd welcome very much if we could agree that we have a problem there, and shift focus from criticizing new ideas to improving them.

To me, we definitely need democracy 2.0. If possible without resorting to meritocracy, but some sound foundation where it's possible to voice disapproval.
I played a version of this on Zoom as part of a Columbia University program [1] designed to simulate the conditions of re-entry from prison, which have considerable structural similarities to poverty and homelessness. The Zoom game is based on one played in person with "stations" representing different institutions and "tokens" representing stuff like money, birth certificates, ID cards, etc. Your hypothetical scenario is quite a lot like the mechanics of this game. I'm working on building a single-player software version of it because the live simulation is rather difficult to stage!

It is indeed unhealthy, and if you haven't experienced not being away from technology for some defined period of time, you won't realize it.

Age: 33. I use the phone compulsively, like the person in the article. I reach for it instinctively when standing still in line, or waiting for anything, or while eating, etc. I have done this increasingly in the past three years.

Two weeks ago I went to play trivia at a bar, hosted by a friend. I left my phone at home intentionally. For the first few minutes it was odd, just sitting there with a beer waiting for the game to start. And in between, I would watch other people, or doodle on my answer sheet, or just think about life.

Today, I went and got breakfast and coffee and read a book for about an hour at the cafe. There was a place for people to put sticky notes about how they're feeling - it made me think about that, and make a submission. I read literature and history around migration and people. I listened to the espresso machine. I watched the homeless man sitting on the corner and thought about it.

There is so _much_ for the mind to do, so many thoughts and experiences to process in the downtime without a device. For me, that often requires not just turning a phone on silent, but leaving it in the car or at home entirely. And it is truly freeing.

If you aren't joking about your opinion, as someone who has lived in both columns, please do an experiment like the OP article. Leave the phone at home for an hour or two a day, for several days within a month. Maybe just a weekday evening after work, or for a walk/drive/brunch one weekend.

The billions of thoughts and pictures and memes, if you are not joking, is useless when you wake up after a decade of accomplishing nothing of value to your own development or happiness or meatspace[1] interaction with the world.

I don't blame my phone or the internet for this. Before smart phones the joke was that people would procrastinate by cleaning their room or organizing their desk. It's not about the technology. When it's time to focus, focus.

I'm sure it helps some people focus, but also sure it's counterproductive for some.

Overall, I find I usually get better non-interactive work done when not in such close proximity that social behaviors are activating. (Interactive real-time collaboration is a different matter, and that has its moments.)

Someone sitting across right across from me, or right next to me, when we're not collaborating, for example? I'll be lucky if I can mindlessly tweak UI visual details, or spit out design or code that I've thought about only superficially. There's no way I could fairly rigorous thinking-through and creative connection-making, in that context, like I can in some other contexts.
What would anyone want with a place that's been nuked to hell and back? Too much issues with fallout and the risk the rest of the world sanctions you into submission, and if you'd bomb it to pieces with conventional weaponry you would have to bomb down so much stuff that there isn't anything left worth invading.

Even without the security agreements that Taiwan has, it's ridiculously hard to invade and take over if one does not want to bomb it to pieces: it being an island means it's extremely hard to land troops and supplies for them (Ukraine has shown that even without a navy, it is possible to sink ships or that it's perfectly possible to run an air force even after almost all infrastructure has been destroyed), and a highly motivated population can and will put up a fight.

China is definitely looking at Ukraine - not just on how the Western world reacts at this clear break with any and all international rules on war, but also how a country under siege and its population behaves.
Indeed, the UK which is further north than the majority of Canada's population has effective vitamin D from the Sun only from March to September. Spring Equinox to autumn equinox basically. The sun is too low even though it might be much warmer than lower latitudes!
That's quite correct. You want an expert in X, you should pay the high price he will ask. Unless you settle for an expert in Y and give him time to get good in X.
Agreed. Years ago I decided to stop texting people as the primary form of contact and instead call them. Now everyone I know calls me cause they know I don't text. This cut down my phone usage by a lot.

I also don't pull it out to pass time, instead I just try to think about my schedule and sort out thoughts. I remember reading someones comment on HN where they said it's ok to be bored, that down time is the best for organizing things in your head, and I've stuck to that ever since.

And although I hardly use my phone I still feel some anxiety not having it when I leave the house.
> A longitudinal survey of the 2020 U.S. voters reveals that harm perceptions predict voting against actual equality-enhancing policies, more so than voters’ political and egalitarian beliefs

The Biden administration has repeatedly enacted policies that send white people to the back of the line in receiving government benefits. The Biden USDA adopted a loan forgiveness program which whites were ineligible for: https://www.politico.com/news/2021/08/24/doj-appeal-minority.... The Biden SBA also adopted a small business loan program that excluded whites: https://www.law360.com/articles/1389372/6th-circ-blocks-sba-.... Left-leaning jurisdictions like Vermont, moreover, have adopted policies such as prioritizing vaccines for non-whites: https://khn.org/news/article/vermont-gives-blacks-and-other-....

How can it be a "misperception" if white people conclude that policies that deprioritize them for access to limited government programs will cause them harm?

The study also makes a critical assumption that supposed "equality-enhancing policies" will actually produce "non–zero-sum increases in resource equality." Some may think that small business loans from which whites are excluded will generate benefits that make everyone, including the excluded white small business owners, better off. Maybe even better off than if those white small business owners had been allowed to participate in those government programs in the first instance. But that's an assumption--the authors are assuming that the intended effect of these government programs will be the actual effect. There doesn't seem to be any scientific basis for calling that a "misperception."
