Prague and Brno would be the two options I'd consider seriously. Prague definitely has a larger English-speaking population, but Brno is not far behind and is generally cheaper. Prague is exceptionally beautiful, however, and so if you are only going for a few months it might be worth the cost (although travel from Brno to Prague is not terrible on the freeway).

It's worth learning as much Czech as you are able to, but you would be fine managing on your own for a few months, especially if you can befriend a local who can help you get on your feet when you arrive (tips on currency conversion, places to eat, places to avoid, setting up a transit pass, etc.)

Life in Prague if you're coming to visit is quite great. I love every minute of the almost two years I was able to spend there and around the Czech and Slovak republics.
I'd have to say whatever the waldorf schools are doing is working. My father-in-law's neighbor is an education PhD and her son has been in waldorf schools from the start. He is the most intelligent, wise, and confident kid I have possibly ever met, and he takes care of a wide range of animals at home (horses, chickens, alpaca, pig). He always seems fulfilled and is always excited to talk about what he is learning in school.

His mom who was previously writing and editing textbooks took a job at a public school in a lower income area of the county. She couldn't stay for even a year as she was so upset and dissapointed with the methodology they were using, heavily relying on screens and allowing kids to get away with everything.

I know that I will definitely do everything I can if I have children to get them into the same school.
> your claim that the QM description is not correct

That's not my claim. My claim is that the change in the mathematical description of Bob's particles (from mixed states to pure states) when Alice measures her particles does not correspond to any actual physical change in Bob's particles.

We agree about the math, and we agree about the outcomes of all experiments performed by Alice and Bob.

There is one thing we disagree about, and that is the outcome of the thought experiment I described above (which may in fact be realizable in practice). I predict that you will observe "retrocausality" in phase 4, i.e. when the experiment halts, Bob's choices will correspond with Alice's measurements with (essentially) 100% certainty. (Of course, this isn't really retrocausality, but it appears that way.) AFAICT, on your view of the world, you would predict (essentially) a 0% chance of Bob's choices corresponding with Alice's measurements.

Just out of curiosity, are you a physicist? Because you obviously know what you're talking about.

BTW, just in case it wasn't obvious, I left out a detail in the description of the thought experiment: In phase 3, if the experiment does not halt at step 4 it loops back around to step 1, just as it does in phase 4.
What retracted papers reveals about science publishing’s ‘death penalty’
I used to know a guy who was asked to explain himself when he referred to his game dev job as “selling crack to kids”. That was just over a decade ago, before the Cow Clicker clones got going.
That sounds about right -- my rule of thumb is that $200/mo TCO is about as low as you can reasonably go "in general".

My last two vehicles were

1. 2005 Chrysler Pacifica. Paid $16,500 in '07. Sold in '17 for $1,900. A few sets of tires, insurance premiums, and (gently) hitting a couple of deer put it around $225/mo over those 11 years.

2. 2009 Pontiac Vibe. Paid $14,500 in '11. Still have it and it's only needed minor repairs (knock on wood). Sitting around $250/mo TCO, but it's still worth a few thousand.

YMMV.

You are right. Price of every item has nothing to do with the cost of making it and everything with how much people agree to pay for it.

Driving down the cost of making a thing doesn't lower the price for everyone, but it widens the market downwards serivicing new el-cheapo customer base.
I respectfully disagree that many low-skill jobs are not stressful. They can often be dangerous, unpleasant, and managed by little tyrants, all of which leads to stress.
Here's the generic C++ version (https://gcc.godbolt.org/z/mMln6L):

};
};

constexpr auto f¨ = [] (auto f) { return deriv(deriv(f)); };

double res = f¨([] (double x) { return x*x*x; })(2.0);

In general, yes. A higher IQ is correlated with handling more complexity.
I am in the market for a new car. I looked at the BMW,Volvo, the Mercedes, Audi and Lexus. I am replacing a Honda CRV, but my needs have grown, and my disposable income is reasonable, so I am looking at this segment of cars.

I would (and in fact, am) taking the Tesla over any of the others, despite my early idea that I would get a BMW. I just didn't like the responsiveness of the car, the clutter and BMW nickle and dimeing me for repairs and things like carplay.

I really liked the Volvo, but the things in the Volvo that I liked - the technology, and the panoramic roof, I could get for cheaper with the Model 3.

I finally pulled the trigger when the Midrange ("Lemur") Model 3 became available. At that point, my out of pocket costs on the Tesla was cheaper then the Volvo and the BMW.

If you have not already tried it - go test drive a model 3. It's a lot of fun.
I've found uber and potentially renting a car is more cost efficient to owning a car and paying parking. I drive so little my car was collecting dust. I still have insurance to drive but that is half of what it used to be. Plus I hate driving in congested traffic.
If you implemented the same compression algorithm over and over again, each time from scratch, the only skill you'd learn would be how to do it more efficiently. You wouldn't learn anything special, except maybe some nuances of the algorithm you didn't already know.

Yeah it's not a skill that everyone can do, but once trained to do it there's no point only doing that same task over and over because you won't advance your skills in other aspects of the field.
Using a reaction wheel.

https://en.wikipedia.org/wiki/Reaction_wheel

Basically, an heavy enclosed wheel that you use a motor to spin. Because of the conservation of angular momentum, the rocket will spin in the opposite direction (more slowly, because it's (probably) heavier).
To be fair you can do that in most modern languages.

(I don't know lisp) but sometimes this approach just makes the code really difficult to understand afterwards. Does Lisp have something that makes it easier or better?
Czech Republic was never part of the USSR. Warsaw pact, yes. Heavily influenced (and invaded 50 years ago) by the USSR, yes. But you'll look a bit clueless if you say it was in the USSR, and people won't take your opinion seriously.
I feel like a contrarian. After deleting twitter and facebook last week, I'm jumping off this smart phone train this week. A factory defect emerged in my smart phone, so I purchased a LTE flip phone. I decided I'm not going back to the smart phone. I know I'm not the average case, but I don't think quitting a smart phone has that much of an impact on the functional aspects of life.
If this does not resolve months after removing stress, it might not be "just stress" and you need to look further. For example I was recently diagnosed with primary hyperparathyroidism after more than a year of vague disabling symptoms and no answers from doctors (I came to the diagnosis after my own research). Just in case, you might want to check your blood calcium. Many doctors when they don't know what is happening will give you a vague diagnosis like "stress" and "it's all in your head" but you could have a real underlying disease that can possibly be treated. Heck, when I explained to my doctor I used to have more stress years ago in college and have lately been basically stress-free after getting a good job, the doctor proceeded to explain how removing stress can cause problems.
Investigating Gmail’s “This message seems dangerous”
I still play sometimes, so I get periodic reminders how it used to feel. (I don't dislike it. It's great fun in moderation.) But the things I spend my time on today are things I wouldn't had done when I was younger (be social with friends I like that aren't toxic, exersize, read, travel), but not because I didn't want to, but because I thought I couldn't (because I was too shy, or didn't have friends with compatible interests). I'm pretty sure past-me would've been way happier doing what I spend my life on now than what he did back then (if he'd only get through the initial no-fun investment hump to actually get the non-toxic friends, or past the point where exersize goes from annoying and exhausting to energizing and fulfilling).

But because I didn't feel like the life I'm living now was within reach back then, I lied to myself about the benefits of video games (so people wouldn't bother me or I felt better about spending my time in that way). That's my takeaway from introspecting on the parents and mine similar sounding scenarios.
That's not at all clear to me. If you put someone into a situation in which there's a reasonable expectation they'll die, and they do, you murdered them. That doesn't absolve another person who may have actually carried out the murder. Responsibility is not zero-sum.
> it would be incredible if there really were no side-effects at all; some people must be allergic? No negative interactions?

Fair enough. Perhaps a more appropriate way to phrase that would be that it using it doesn't require any more precaution than trying any other new food for the first time.
>> It took the lawyers an average of 92 minutes to complete the NDA issue spotting, compared to 26 seconds for the LawGeex AI.

Issue-spotting an NDA is not a typical task for an actual lawyer. It is the sort of thing handled by a legal intern or paralegal... then signed off on by a lawyer. It isn't typical legal work. The results are therefor of limited application in the real world.

Better test: Client asks "Do I need an NDA?" or, conversely, "can I break this NDA I signed last year?". Ask C3PO to handle that question. That is the sort of problem where the real legal expertise happens.
Wasn't there a year recently where reliability skyrocketed? 2004 or something? I thought I heard there is a clear cutoff point where you should not consider buying a car before that date.

Unclog Bathroom Sink Faucet: A Simple Actionable Procedure
For many, many years I have had a personal benchmark in mind when purchasing vehicles. I want my TCO to be < $1000/year barring routine costs like fuel, oil, tires.

So if I purchase a car for $3000, I expect to own it for 5 years with minimal problems. There is room for a bad alternator or a starter. But not too many of those over that 5 years. Of course, if I can sell it for $1500 after the 5 years, that's another $1500 I can sink into maintenance and still justify that it cost me < $1000/year.

If I spend $10K, I have to think the car will be reliable for 15 years with ~$5K of repairs along the way.

In the past five years or so I have thought I might need to raise that $1000/year figure to reflect modern practicality. But, surprisingly, I haven't really needed to. Cars are becoming amazingly more durable, and prices in the used car market aren't sky-rocketing the same as in the new car market.

Still, it is time to make the transition to electric. The used electric market is still very immature. I don't want a used Prius. I'm ignorant of how to value used batteries, so I'm not sure what the maintenance costs will be on an 8-year-old Honda hybrid with original batteries. A 10-year-old Tesla is still way beyond $1000/year. To step into this brave new world will probably require me to suspend my $1000 rule until the water settles a bit.

Or I can pick up one more ICE car and stretch it out for 10 more years while things sort... Or compromise and just get a series of 3-4 year clunkers until I'm ready to dive into electric.

Or just bite the bullet and take the plunge now...

> I fear a child who hasn't learned to cope with technology for 13 years and is then suddenly introduced to it will struggle far more.

This is also one of my bigger fears. There is a strange mix of people in my generation (born 1990's), who are non-techies, and are either responsible with their internet use or display worrying signs of unhealthy internet presence. Even though tech has been around for some time now.

Some, I realised, were introduced to technology rather late. A fun example is how some people would be offended if I were to call them "gamers". They don't own PC games, don't own a console, but they spend their entire commutes and more playing mobile games.
Yes, most relationships have some sort of power imbalance (although historically that has been drastically decreasing). What makes work relationships different is that it is hard to change jobs.

If you decide to go date a rich man on Tinder, you can break up without significant consequence to your income or your career. But if your boss asks you out you may face severe career consequences just for saying no. If you say yes and then break it off, the risks to you go up.

This rule has no assumption of guilt. It's just acknowledging the risk to the company and the people involved.

It's more or less a meme from a popular series of books, implying that someone's naive.
> I'm more annoyed that everytime video games come up, someone brings up Civilization as a strawman to argue.

> 99% of games aren't Civilization. We all know people are talking about that 99%. The article even calls out that the parents make exceptions for some educational games/screen time. And yet rather than legitimately engage and address peoples concerns about video games, it's always the same argument of: raise the benefits of Civilization, share nostalgia about playing it in the past and ignore the actual arguments being presented.

> This thread is no exception. This is a place of more intelligent discourse - address the opposition's points, or concede they are valid.

If you had carefully read the comment you’re replying to, you'd have noticed the GP is addressing the claim “video games can be educational”. Not “most video games are educational”, but “video games can be educational”, which Ms. Stecher seems to be denying. Thus it makes perfect sense for the GP to present an example.

So before hypocritically accusing others of “strawmanning”, “unintelligent discourse”, and “ignoring the actual arguments being presented”, please take the time to read what people are actually saying.

And while 99% of games aren’t Civilization, I’d need a citation for the claim that 99% of games aren’t educational, if that’s what you meant to imply.
I used to be a used car person, then after I got my first new car I became a new car person. When I get a new car, it is still a new car to me even after 10 - 15 years. My previous new vehicle cost just over 20K, and lasted about 15 years.

When I bought used cars, in the 2-5K range, they would last about 3 years before I felt I needed to trade them in, and I'd be constantly working on them. A new car gives me a break for about 8 years or more before I really have to work on them (other than regular maintenance). And that is really nice knowing that I can get in the car in the morning, and have a really high rate of confidence that I'll get to work and get home.

The other thing, having a car from day 1 means that I know how it was maintained. The biggest item is having it garage kept, keeps the morning dew off it and therefore have fewer problems with internal components (and rusting) over time.

I think consistent exercise is extremely important as well. And it should be right sort of exercise. I found yoga to be a key activity. It leaves you alone with yourself, no one to compete with. You eventually have to succumb yourself and just exist. There are some varieties of yoga like ashtanga which in my opinion is best for this.
Ask HN: Lost $10k as my email was hacked. Any ways to recover it?
I have suffered a loss of $10k due to an extremely unbelievable case of my client's as well as my own email domain was hacked.

–----

So, I run a very small pharma export company in India. I have a client in Ontario, Canada with whom I have been doing regular business.

2 weeks ago I got an order worth $10000 from them. So as usual I dispatched the material to them and then raised the invoice with my bank details from my email address called "abcde@mydomain
.com".

Now on the next day my client received an email from "abicde@mydomain.com" stating that there is a change in invoice and revised invoice is again sent which had bank account details of a UK bank account.

Now an email like "abicde@mydomain.com" doesn't exist at all.

My client asked me for a confirmation email again but this email never reached me. So the client made the payment and the money is already deducted from his account.

Also, what makes this even more strange is that I received a fake email from my client's company with 3-4 times about not asking for payment as it will be delayed.

I got this email from an email address like "klye@clientdomain.com" instead of "kyle@clientdomain.com".

Now $10000 in an extremely huge amount for survival of my company. I want to know what are my options and is there any way of recovering it.
> It was just the same about 23 years ago

Did your cousin carry the TV around with him?

> TV and computer isn't something new. People were addicted to mobile phones even 10 years ago

It used to be rare to see teenagers with cell phones, let alone toddlers. The iPhone is ~11 years old, and in that time it has become common for me to see people of all ages, from toddler up, always on a smartphone or tablet.

I disagree strongly that the situation is just the same as TVs decades ago.

And I'm not interested in the picture of the people reading newspapers on the subway. It's always been common to ignore strangers of public transit, I'm more interested in a photograph of friends/family staring intently at their own newspaper while at a dinner table or some other social event. This is the norm with smartphones, and color me skeptical that it isn't new.
> Investors rarely want to dictate what and how you do things, in my experience.

West coast capital is significantly less interested in the what and how than other sources of capital in my experience.
A WD 4TB external drive can store 160 25TB blurays for $100. That adds a "tax" of $1.60 per disc if you rip the raw disc.

I tend to re-encode as libx265 (preset veryslow CRF=18) which is a fairly transparent reencode at 20-40% the size, which lowers the storage cost to under $1 per disc. If you also have backups, that will double the cost, or you can accept the risk and re-rip them if you lose the drive.

[edit] They have 6TB and 8TB options now that are cheaper per-disc if you have more than 160 bluray movies.
One exploit - everywhere.
For me, at home, I'm doing very little. 90% of what I'm doing on my personal laptop these days is in a browser. ChromeOS is a dead simple, secure, browser appliance.

Being able to install an Android SSH client and VPN takes that up to more like 99% and lets me do some work things as well.

Being able to install a Linux app or two would probably take me more to like 100%. The only thing I really want to do that I'm not at the moment is have a more self-contained development environment like VSCode to dabble on some python rather than sshing over to a box and editing in vi.
Excessive precision
Heh, one of the awful things they did when they acquired Skype was rebrand a bunch of pre-existing products in the same general space with the Skype name, causing a huge amount of confusion. Hopefully they don't slap the GitHub name on everything under the sun; I'm optimistic, right now it seems like Azure and Office365 are the two catchall branding efforts.
For a public company the size of Tesla, unaudited will be the same as audited. Sometimes in the MD&A, they use adjusted figures because it tells a story differently (maybe more accurately) than un-adjusted GAAP figures.
In many ways it is the parsimony that is beautiful. There is a ton of syntax in lisp, but there are not as many punctuation requirements. And you get to play with the grammar and many parts of syntax yourself.

Contrast this with most other languages, where there are many things the language does that you can not do. At least, not easily.
About those "jaw pains," I would HIGHLY recommend you get a bite / stunt to wear at night. You never know when you could start grinding your teeth at night (you really don't know, because it happens when you're the most unconscious) and you could ruin them in a very short time. Forever.
> Are they substantially more dangerous than other things I do in my life? Probably not

Depends on the other things you do in your life, but statistically, I would say: probably. Rock climbing, assuming you use a proper harness and rope, is significantly less dangerous.
What is the most corrupt thing you've witnessed at your workplace?
That's the US, but the charger network argument for example looks very different in Europe or China.

And while Tesla has a good share of current capacity, the amount of capacity that is being built and will come online in China over the next few years is many times larger than what we have right now. Further, while European manufacturers and industry threw away a healthy position in battery R&D over the last decade or so, there is every indication that they are correcting this mistake. Whatever is going to succeed as the post Lithium-Ion tech might well not come out of Teslas labs.
Yeah. It used to be a lot worse believe it or not. But, still, anything over about 10 years old in the Northeast and other snowy regions are pretty much at EOL. I made the mistake with a prior vehicle (which I bought used) of doing a couple fairly major repairs when it was about 12 years old and it ended up being just a cascading set of failures due to rust.
My concern here is abuse of power, so I would not make any additional rules in this case. If the junior person is bothering the senior person that's unprofessional conduct and so can be dealt with normally. If the senior person isn't bothered, I don't see why it's any business of the company's.
Can you print an example of the random test error? I run a decent sized phoenix project (150K lines) and likely can help you out if you give a bit more detail.

With regard to associations, for simple belongs_to associations I will usually write separate changeset functions where the first argument is pattern matched against the record. I will give an example with Post/Comment

defmodule MyApp.Blog.Comment do
def changeset(%Post{} = record, params) do
record
|> build_assoc(:comments)
|> changeset(params)
end

def changeset(%Comment{} = record, params) do
record
|> cast(params, [:body])
|> validate_required([:body])
# Continue with validations, constraints, etc.
end
end

In this case the changeset function calls itself once it handles building the association. For more complex conditions, I will usually write a "Form" module that may handle that case usually with a Enum.reduce combining multiple calls to `put_assoc` so that I can make nested associations in one insert.

Hope this helps a bit.
