> Fiat is backed by weapons.

I interpret this to mean:

The major fiat currencies are ultimately backed by their respective government's willingness to use war to preserve their economic interests.

The other fiat currencies are based on the level of mutual interest in economic partnerships or trade relations between the majors and the non-majors.

...

This is intuitively sensible to me, but I am not an economist.

This seems like a kind rational economic choice. If there are not enough good jobs that can support independent living, providing for a spouse, buying a home or raising a family, then staying home with the easy accomplishment of video games makes sense. Most people never live outside their home states and can't afford to leave the support network of their family and close friends. If you grew up in a medium or high cost of living area, then you're sort of stuck. I work in tech and still, owning a home seems pretty distant, so I can't imagine how it must be for someone without job skills.
My final project is due one month from now and I don't have an idea
Hey! Hope everyone is doing great today :)

Guys I have one month to think and implement a kickass idea that will show off my skills in front of a very important crowd of talent-seeking individuals.

I need your help to think of a project!

My skills to work with:
- GraphQL
- Nodejs
- Puppeteer/Cheerio web scraping over tor.
- React.js
- MongoDB, mySQL
- AWS

What do I like?

- Backend stuff over frontend, but enjoy all.
- Something that might be useful for people, that would have value.
- Something impressive to the potential employer.

What I've done:

- A Spotify clone that is based on web scrapers to get literally every song available on YouTube and stream it's audio to your device - feels (and looks) just like real Spotify.

- A collaboration platform for open source projects with teams and resource sharing.

- A flexible web scraper capable of getting various inputs from multiple pages, depths and selectors, clicking elements, scraping whole forums including Tor websites, and getting real time alerts for any data received that is offensive, violent or illegal using my own NER and sentiment system.

What I'd do if I had the skills to do so:

- Probably a complete self-hosted email service that can be relatively off-grid.

Please help! Thank you :)

Cutting after mid day is wise. Every liver clears caffeine differently. There's a threshold where your liver won't actively process caffeine if you don't drink enough. For me, I sleep better on two cups in the morning but just one will keep me up all night.
It's also rare to see maps where south is at the top, but that's also an arbitrary decision. North isn't "up" any more than south is.

Did you know about HAKMEM 169? I guess it was/is not widely known since many people mention lookup tables as the only fast alternative to the popcnt instruction.

So it’s better to put yourself in a position where you are forced to drive an hour to work each day and spend 10 hours away from your infant just to get an hour to yourself?

Also this isn’t about your infant, no one is getting work done while watching an infant.
>The research industry

I see this as an oxymoron, it's the kind of scenario that makes for bad science such that no amount of incentinves, discincentives, and/or "metrics" can fix.

From "research industry" I get the idea that they want industrial-scale scientific production. Industrial activities are all about roughly predictable outcomes and mostly steady productivity output.

On the other hand scientific research seeking real novelty is---because of the novelty, very unpredictable. So when I read "research industry" I think they refer to "industrial novelty-seeking".

I can imagine somebody saying "we need 10 completely, gound-breaking scientific research articles peer-reviewed every quarter for publication!"
When they've learned that your base heart rate is ~70bpm and when you get shown a puppy your heart rate excites by 20bpm they can guess that you like puppies. They could be wrong, and it could be that you're actually terrified of puppies, but they'd be safe in assuming that you're a big fan of them and so they add "Enjoys puppies" to their advertising profile of you.
Ask yourself this: Assume that you have little or no knowledge in foreign countries, but you want to purchase some of their currencies - how would you go on and classify these currencies as "good" or "bad", when viewing them as potential investments. Besides simply looking up their historical exchange rates.

It's obviously a complex problem, as we're dealing with parities here - but war/conflicts, poor economies, extreme inflation, and similar factors will drive the currency down. On the other hand, peace, strong economy / industries, etc. will drive them up.

One might associate the intrinsic value of a currency with the overall economic health of its country, along with things like geopolitical stability, internal policies, and what not. It's a good mix of micro, macro, and politics.

With cryptocurrencies, it's a bit harder to measure things that like. It's a stateless currency, with no industries or workers behind it. There are no wars or conflicts either. No policies made by politicians that can affect its value (in the abstract notion).

Essentially, you only have supply and demand to go after - when trying to predict its future value.

Look at drugs. You have alcohol which by any measures is bad that’s widespread and people do dumb stuff while on it all the time. Ban it? Nah fam, it’s just good fun. And people enjoy it and it doesn’t hurt anyone, right? RIGHT?

And you have “hard drugs” that are bad for ya and you’ll end up doing hard time if you ever get caught remotely near it. It’s for your own PROTECTION!!!1

Amend the bill to include all consumer electronics manufacturers must provide replacement parts for all their new products for twenty years. The churn of slightly different pieces in next years models should fall off a cliff when warehouses need to get built to hold everything.

Or something
That is the rub with most of this 'data'. Each one by itself it is nearly meaningless. But tossed together it creates a much more interesting thing to use. Like my DOB is borderline useless. But combined with a few other random bits of info and you can target me nearly exactly. The amount of random info is not much at all either. Add in a metric like gets depressed/excited by, and the intrusion gets even deeper.
> If the value of their currency drops substantially, will they go to war with some unknown power that's causing this drop and reverse the change?

They might - that’s essentially what the U.S. has done (or, at least, did for a while) when other nations tried to break the petrodollar system.
I lived with my parents on and off until I was 31, that was when I managed to marry and move out hopefully permanently this time.

It is Anedacta... but I think I know what is going on.

1. The labor market is a mess, for example today I got another rejection letter from a job I sent my resume, thing is, I am literally perfect for the job, my resume (that I didn't tailor for it) matched perfectly what they asked, even the "additional" things, including the fact they wanted someone that made Hidden Object games before (I had a whole company to make those with millions of downloads).

I have a strong impression hiring is just screwed, people often don't even read resumes, for example I had a company invite me to do a job I don't know how to do, only for the interviewer of the company realize they are wasting time (a company asked me to do ML work, I never listed ML anywhere in my resume).

Also I am 33 now, and never had a job registered legally in my country, I only had contracts and "contracts".

Also here having internship is mandatory to graduate, a lot of my friends failed to graduate beause they didn't found any internship even for free, to graduate myself I actually created a company and hired myself (it is legal to do that O.o).

Now relationshipwise: I looked for relationships very hard, and kept finding only people wnating flings, including one person that scammed me (she claimed she would marry me and whatnot to convince me to have sex with her, since I wanted to marry virgin, after she got bored with me she declared that all she wanted was my body and kicked me out).

Only reason I managed to marry at all, is that I went to a church, found a childhood friend there that also wanted to marry and was having similar issues, and I asked her right off the bat if she wanted to marry me then, and she said yes. (we are very happy, for those wondering...)

If it wasn't for a lucky coincincidence (in case you don't believe in God or something... I only went to that church because my car broke that day when I was going elsewhere and going that church was in the situation at the time the logical option) I probably would still be alone.

Same thing applies to a lot of my friends, many, many of them are single, and jobless, after a while some of them just give up on living properly and settle for videogames... videogames are not the culprit, they are the escape, they are a solution to have a life, even if virtual, after your real life becomes seemly impossible to live.

EDIT: by the way, student debt doesn't help, for example I did got "legal" job offers, but to earn mininum wage (for example supermarket cashier), thing is, my student debt monthly payments was roughly twice the mininum wage, so accepting a mininum wage legal job would put me in further debt. Thankfully my Startup Kidoteca was a reasonable success and I paid my debts with it.
In addition to Matterport, mentioned in another comment, there's FloPlan, which has the agent walk around the house taking a video of the baseboards, and constructs a floorplan from that. Not entirely accurate, but good enough for a rough idea of the layout of the space.

I believe it can also use the LiDAR sensor in newer phones, but I haven't tested that.

An easier sell than Matterport, which (IIRC) is a $5K camera. FloPlan just charges a per-plan price (again, IIRC).

well, there's also the force of law behind stop signs.
What does effort mean in this context? I recall friends of mine, young women, who were having the hardest time finding a significant other were just demanding things of men that would have them selecting from a socioeconomic pool of the top 20% of the population, when they themselves were in the bottom 20%.

It was my experience that young women in general were asking for too much when I was in my early 20s. They wanted someone who had it "all together," and that's just not where most people are in their early 20s. There doesn't seem to be any appreciation anymore for the fact that young couples grow up together. Instead, people seem to think that you grow up first and establish who you are independently, then find someone else to bring into your life. But realistically, you don't finish growing before dating, and in life who you become is based on the interactions not just with your significant other, but your friends and family, too.

Lastly, all of my dating experiences online lead me to women who wanted to be "entertained." And not in the sort of "wined and dined" sense which seems obvious to me, but rather most women I came across didn't want to get to know men, they just wanted entertainment value out of the experience of dating. This was a sharp contrast from interactions with young women in real life. The dating world for both young men and women online seems to create some strange scenarios that don't play out well for anyone involved. I see this manifest the most in online dating where most men are naturally led to play pickup artist lines. I personally find it extremely off-putting. I'm not a jester.

> Stories about children either passing out or dying because they were required to wear masks.

Do you have any citations for these events, because they seem to be absurd misinformation.

The country I'm in (Singapore) has legally required masks in public since last year (as have many other countries) so everyone is wearing masks, and so far, I have not heard of a single case of people suffering due to wearing masks.

In fact, I even wear my mask when I go running and I have never felt any significant issues with breathing, even after hours of vigorous exercise.

If masks could reliably cause breathing issues in any significant way, given the number of people in the world who are wearing masks every day, we should expect a statistically significant number of such cases, not just a few cherry-picked anecdotes.
There already is some basic file I/O in CBQN (though not complete yet). Format parsing isn't hard to do in BQN itself, and finishing the base implementation is a priority over fancy built-in interfaces for now.

> Make no mistake, though, for a young man who’s not working the couch isn’t a bed of roses. “About half of prime age men who are not in the labor force may have a serious health condition that is a barrier to working,” the late Princeton economist Alan Krueger wrote in the Brookings Papers on Economic Activity in 2017.

Does it really sound that appealing to be "entitled" to pain, high medication costs, and/or a potentially crippling drug abuse problem?

Go ahead and fester away, bud.
Regulatory capture, and gutting regulatory organizations of any teeth they may have once had. The money is going somewhere, and it's not to help the average people.
I worked with C++ & MFC in mid-late 1990s, smart pointers weren't an option. Maybe if you do something against MS oddball APIs, but not in general programming, not even for mainstream MFC uses. And what was there was entirely non-idiosyncartic, it's like claiming C++ had garbage collection in 1990s because you could bolt on Boehm's.
1. Unicode has no idea of "bytes" at all.

2. Only in the UTF-32 encoding, which no one uses, are all characters represented by 4 bytes.

Most sites today use UTF-8 where most characters on a standard keyboard are 1 byte, and almost all characters from any language take 3 bytes.

3. Even 19 characters is a lot better than 12.
At this level they're just resume harvesters. What's really crappy is they reach out to you making it sound like you're Just The Perfect Person for their role, then hand you a pile of shit you need to study to ace the interview.

Guess I'm not the perfect person then or else I'd know all of this, right? Fuck that.
Do you believe Johnnys has the resources to create a secure payment system and keep it secure?

It's also the first time women have been allowed to opt out. Working most of the day is the historical norm for all able-bodied people and most not-wholly-able-bodied people.
We can’t know the cost without knowing the value. Nothing will happen to the data unless someone buys it.

To identify the costs, we’ll have to think about who might want to purchase this data and what they could do with it.

Ask yourself this: why would anyone be willing to pay for your heart rate?
Anecdote: I’ve seen a dozen people roll through stop signs today.
The "perception" of voter fraud in the US is itself entirely a fraud, created to allow rules that make voting harder.

Mechanisms like mandatory voting and greater access to polling places (and holidays on voting day) are exactly the opposite of what is desired by those talking about voter fraud. So while there is much talk of voter fraud, those options are always off the table.

Voter fraud just isn't a significant thing in the US. The perception of it won't be fixed by dealing with voter fraud, one way or the other.

Unfortunately, that means that the real problem is much harder. It's a combination of authoritarianism, partisanship, and xenophobia, deliberately exacerbated both within and without. We don't get to spend much effort on the genuine issues because we're too suspicious of each other, and spend all of our time fighting about non-issues.
If we were looking at kids with sleep trouble who stayed up late with bright screens blasting hyper-stimulative entertainment and carnival-bright indoor room lighting, and we believed that sleep quality and quantity had gotten worse for kids over the decades as room lighting had gotten brighter (y'all seen a '50s or earlier house with electric lighting that hasn't been re-wired? They're not lit up like a modern house, usually, and lower-light set-ups continued to be fairly common, if less the overwhelming norm, through at least the 70s) and electronic screens per house had moved from "none" to "one tiny one" to "several per person, in many sizes", the very first thing we'd do is cut off their electronic screen-having devices—all of them, not just cell phones, all of them—and lighting brighter than ~100 lumen per room strictly at sundown. "Well of course they can't sleep!", we'd say, tutting and looking on with the authority and perspective of parents.

"But I'm having trouble sleeping and I'm bored, can't I just watch a couple episodes of something?" they'd say. NO, we'd say. "Well how about I work on some homework on my computer?" NO. "Alright, well I guess I'll text my friends" NO. "But..." NO.

And if sleep across the population of kids had indeed been getting worse over that time period, I'd bet that'd fix it for most of them.

We have trouble enforcing rules like that on ourselves, though, and maybe even trouble recognizing what's surely suspect #1 in any kind of declining sleep quality epidemic.

(as for any "tricks" we're all sharing, the ones I've had success with are: a loud and powerful fan for air circulation and noise-masking; keeping the thermostat for our bedrooms quite low at night, even in the Summer; heavy curtains; and a weighted blanket, which if nothing else is very good at keeping any sheets or other blankets under it in place all night—and yes, I'm terrible at sticking to the obvious solution above, just like everyone else, but damned if it doesn't work like a charm on my stupid "I think I might have an abnormal sleep cycle LOL yeah, must be that, not all the low-effort hyper-stimulative entertainment" ass)
How do you check for whether you have this mutation? Sequence your genome? Any recommendations?
Small difference: neither currency nor stops sign have speculation as rhe primary usage.

There are rural towns that have a completely different concept for a stop sign... backed by a lack of enforcement from officers.
Most prominent metals have considerable industrial use, which makes those metals valuable, and makes them de facto backed in a big way (by the demand for them). Bitcoin has modest industrial/economic use, at present (and obviously other cryptos may present different advantages in that regard, given time).

You also can't physically wear Bitcoin and show off status, unlike Gold, Silver and Platinum.

If gold gets cheap enough people will use it in their wallpaper because humans have an insatiable demand for luxury goods. That will never change. It's why people still adorn themselves with sparkly rocks and shiny metals after 20,000 years of supposed evolution and refinement.

The store of value argument for Bitcoin is fully legitimate; as are the arguments for building potent economic uses on top of blockchains. There's no reason humans can't invent superior stores of value, and ever better transaction & contract systems. However, those various valued physical metals are not unbacked. Bitcoin is unbacked, and it can be replaced by other coins in the near future, coins that are technologically superior for storing value, and so on. The properties that we like metals for, industrially, make them difficult to replace in most cases; the demand - at an industrial minimum - will remain for a long time to come accordingly. And the human population keeps expanding (~80m per year), the odds are zero the next two billion people will suddenly stop having any interest in wearing/owning gold as a status symbol, and that puts an enormous demand factor under gold (on top of the fact that the median has gotten richer, so their demand for luxury goods has skyrocketed; see: China 1990-2020).

Try mining new sums of scarce metals, or any metals for that matter. Try inventing a new metal.

Now try cloning Bitcoin or Litecoin. Trivial, relatively speaking. There are thousands of bullshit crypto clones, and there will be thousands more to come. Bitcoin is temporarily special due to acceptance. There is little industrial demand under that fickleness however, which means Bitcoin can easily fall out of favor, exchanged for the next popular fad coin that people decide is the better way to store value (click, click, you just converted your Bitcoin over to the next more popular coin, byebye Bitcoin; now try that process with physical metals that you need for manufacturing purposes).
> another friend of mine basically refuses to date anymore because he thinks the sort of culture of Tinder dating is a waste of time that favors women disproportionately.

Tinder is a waste of time for women too; if you’re at all attractive you get dozens of messages a day and half of them are scams. The best I’ve ever gotten out of Tinder has been mediocre, meaningless sex; it’s far too much work if you’re looking for anything more.

You have to go do things you enjoy and be a more interesting person. If that’s just your daily life, you’ll meet people who enjoy the same things you do and you can potentially date them (or their friends).

But yeah, I agree with you. Just because Tinder sucks doesn’t mean you shouldn’t date; just that you shouldn’t look to an app to find a partner.
If you know about Lyapunov coefficients then you should also know about the concept of order of accuracy. If I'm developing a code that is supposed to be second order in time and space, then when I'm running my convergence study, I better be able to control the floating point error in my computation of the total energy, so that I can properly attribute the error I do observe to power series truncation, or what have you.
