It sounds like you are an upper middle or upper class family. There are gifted children in the US that aren't identified as such that come from lower class families who are deprived of their education. I checked the AoPs site and if you get the pre-algebra -> calculus textbooks + solution guides it's over $200. This may not sound like a lot to you (as you suggested) because it is due to your class. This is something some poor families cannot do. Even if they want to buy those books. Sending your middle schooler or high schooler to take college level classes is another sign of class status. I believe we should have schools like AoPs and the Proof School targeted not at the wealthy gifted children, but poor gifted children. I also think these schools shouldn't filter applicants out by SAT scores (since mostly gifted children from well off families seem to do better than gifted children without access to education). It seems like most places ignorantly assume the gifted only come from well-off places and put cultural barriers (such as exams) to identify them. This class advantage carries over into university admissions when the well-off students have 30-60+ credit hours from colleges coming in, as opposed to the gifted kids from poor families with 0 college credits. The former are admitted to elite schools, while the latter are denied. If you look around, these elite prep schools and elite colleges tend to lack economic diversity. Teaching advance math to gifted children of the elite, while excluding the gifted children of the poor (due to barriers of entry) do a disservice to our society as a whole.
For me, being self sufficient for maintenance dramatically alters my cycling experience. Taking my bike to a mechanic would involve loading it into a car and driving it somewhere, waiting, and repeating the process when the work is done.

Naturally, it can take time to get parts, so if something is actually broken, then the bike is out of commission for a while. But a minor benefit of poor urban planning is that I've got space for a spare bike or two, or three, plus a bucket of spares that I've collected over the years from trashed bikes. ;-)

Also, doing the work at home means that there's less of an impediment to keeping the bike in good adjustment more or less continually, so parts don't come loose and start to deteriorate. Major repairs become less frequent. More or less weekly, I go down into the garage and check all of the bikes in the family fleet. The effort is practically trivial. I also involve the kids in this work, whenever possible.

With an eye towards doing my own maintenance, I choose my battles when I get a new (or more likely, used) bike. I prefer parts that are likely to be reliable, and that are straightforward to adjust without a proliferation of special tools.

I think Us-Them is much larger than two-party. When you look at countries with multiple parties it doesn't seem their political systems are wildly more efficient.

I think US vs THEM is incomparably bigger than the question of politics. Would 9/11, Vietnam, Iraq, hollocaust, or most wars for that matter have been possible without Us vs them? What about most corruption? What about class systems?

There is somewhat similar concept of Bitrate peeling [1] in Ogg Vorbis. You can drop portion of the stream without transcoding and still be able to decode original audio at lower bitrate. With proper over-the-air modulation and multiplexing scheme (like ADSL interleaving), one should be able to have graceful degradation of digital audio.

Love it. It's one of the most well-designed electronic devices I ever owned. Rally fun to use. I think it's worth studying as an example of great user experience and designing for "emergent" features - even if you don't care about synthesizers all that much.

Also, OP-1's synthesis capabilities are much deeper than it would seem from reading the manual or watching a typical review. And it has an amazing online community.

>The impossibility is not due to methodological defects in the current state of scientific practice. It's intrinsic to the world. If you cheat only a bit, and only rarely, it might be impossible to detect it statistically.

I don't understand what you're saying or maybe I just want to go further. But I would say it's an ill-posed question whether someone's cheating in that sense. They could win a one in a million chance repeatedly over and over on their first try and it wouldn't be proof that they're cheating. It's not even necessarily probable. The probability that they're cheating depends not just on how good their results seem to be but also other things, primarily: on your priors about how likely it is that they would cheat.

If a known cheater gets a string of mild good luck it is more indicative of cheating than if a known honest person does. Bayesian reasoning has to be used for this right?
Harder questions:

- Is it bad for us that Facebook is aggressively monopolizing the social media/interaction space by:
* Abusing its data collection (including through its purchase of Onavo) to eliminate/buy out competition
* Storing our social data in a closed garden with no easy way to migrate it out into a different platform or even provide an API so that other social platforms can interact with Facebook

thus limiting our options for exploring different options for online social interaction?

- Is profit taken into account in Facebook's feed algorithm, or is it just our well-being (encouraging active social interaction, as the article describes) that's being considered?

I've never heard of anyone playing like that before actually. And it seems to completely mess with the statistical nature of the game. Even if you shuffled them each time, shuffling methods are bad and you probably wouldn't get a nice normal distribution. Which fair dice produce.
In my understanding Cuba has shown remarkable development in it's land stewardship after the collapse of their trade with the the USSR. They developed local and sustainable food distribution systems that don't rely on industrially produced herbicides and fertilizers.

I can only guess that the initial explosion(s) would knock out the systems on ones coming after, so a huge percentage of them would be dead on arrival, unless they were decently spaced out, or somehow all arrived and detonated at the same time. (I guess explosion interference from previous explosion is a serious topic of research when it comes to nuclear warfare, if anyone has any good reading material on this please post)
Semedo, head of the UN's Food and Agriculture Organization, claims in the linked article that "generating three centimeters of top soil takes 1,000 years."

But the organization says of topsoil formation on its own web site:

The rate of topsoil formation can vary from < 0.25 mm/year in dry and cold environments to > 1.5 mm/year in humid and warm environments (Hammer 1981; Hudson 1981). Topsoil formation at the rate of 1 mm/year is equivalent to an annual addition of 12 t/ha. Therefore, the rate of topsoil formation has been considered as a factor in the model in assessing loss of productivity and tolerable soil losses.

http://www.fao.org/docrep/009/t0733e/T0733E06.htm

1 mm/year means 30 years to generate 3 cm of topsoil, not 1000 years. And human intervention can increase productive topsoil rather than deplete it, when the incentives are properly aligned.

I don't know if the 1000 years figure is a mistake, based on newer, more pessimistic measurements of soil formation rates, or something else.

I am very in favor of mandatory service as a strategy to improve nations but I do want to point out that some of the most impressive ones (South Korea and Israel come to mind) are extremely homogenous.
"forced camaraderie" misunderstands camaraderie. The US GOV didn't force people to work together in WWII, it invited them to work together and people rose to the occasion.

Nationalism gives people a way to draw the friend/enemy distinction at the border and a way to resolve differences without civil war.

To the extent that America draws its friend/enemy distinction inwards, civil war becomes inevitable.

It's a real bummer that we think of nationalism as a dirty thing, in its highest form it should be collaborative. One can believe that America is for Americans and illegals need to go back AND believe that those people should improve their own country. The MAGA crowd wouldn't resent Mexico for doing well, or at least there'd be less resentment than the status quo where Mexican nationals come here and misbehave.
Thanks for the positive take, but I do think that folks are justified in their anger.

Perhaps, I grew up on them though and have only ever owned an Apple computer (starting with iBook clamshell in like 2001?)

Edit:

And in reality how do you like the USB C ports? What headphones do you use? Did you have to buy $500 of new cables?

Don't take this with an off-putting tone, I genuinely don't know if its worth buying thousands in new accessories and adaptors to replace things like HDMI, USB-A form factors, etc.

Edit #2 - The Trashcan Mac Pro was built on the theory of daisy chaining Thunderbolt, and not 3 years later we see a new standard port in USB-C. I know its a niche audience, but my point is, what if USB-D is out in 24 months, and your $3,000+ of cables/monitors/harddrives/adaptors to use an SD card with your camera.... are all obsolete?

Edit #3 after reading the rest of the thread: Seems you are in the minority and others echo my complains of post-2015 Macbook hardware being extremely underwhelming and not worth the frustration.

Depends on the research method. If it was only backwards-looking, you'd be correct. However, it sounds like there was an experiment with a control group and a treatment group.
Ask HN: Know any operating systems for seniors?
I recently discovered the existence of Telikin which are computers marketed to senior citizens using a fork of Tiny Core http://www.telikin.com/ http://www.telikin.com/open_source

While I was impressed with the os, I wasn't so impressed with the price of the computers 800USD for a laptop with a Pentium processor.

My Grandma already has a laptop that she barely knows how to use, is there any (preferably open source) OS's that are targeted at Seniors?
Great point on attaching an emailed cover letter as a PDF. Never thought about that, thanks!
If by waste you mean excrement then this is not a good idea in the slightest. First you have bacteria, viruses, and parasites that must be killed off. If it isn't properly treated, you end up with a situation similar to that of what we saw in the recent North Korean refugee who suffered from parasites. After that, as you mentioned, there are pharmaceuticals which are notoriously hard to filter out. Next on the list is heavy metals that can become concentrated in excrement. Even after addressing these concerns, if the process to treat the waste is too costly, then there goes the benefit.

I would compare some of the challenges this faces to those that are faced when turning salt water into fresh water through desalination (probably not a direct comparison).
The English version of "The Netherlands" is actually the correct way of saying our country's name (I'm Dutch as well).

Look at your passport or ID card: It says "Koninkrijk Der Nederlanden" not "Koninkrijk der Nederland".
I would add: the reason it is a issue in C++ is because the algebra around pointers doesn’t support the NULLs explicitly:

- the results of any operations over nulls run as if the pointer were not null
- while anyhing you do in SQL with NULL would explicitly have a mapping to either a correct value or another NULL

This is all said knowing that it’s quite easy to understand why is that the case.
Sure, perhaps there's a difference to be drawn between "is in competition" and "is competitive".

Disney is currently able to _try_ to compete, but their new streaming service is not competitive due to a lack of content, and won't be for years if they try to build up their portfolio organically as Netflix did.

If they bought 21st Century Fox, then arguably they would be immediately competitive with Netflix.

This is a classic build vs. buy decision, where (regulatory concerns notwithstanding) it's often better to buy as a well-funded new entrant that's trying to catch up with an incumbent.
It's funny that you mention Cuba because they actually do take care of preserving their soils, unlike most of the Caribbean which has completely degraded soild due to centuries of sugarcane plantations with no regards to the environment whatsoever.

I can't think of any examples in which it is good.

Bad actors exist in the world and can and do team up. If you adhere to the view that Nobody Is Truly Bad that's nice but you won't be able to defend yourself or anyone else when attacked and thus raise the incentives for non-cooperators.There's a reason your body has an immune system.

The easiest way to get a derailleur limit setup is to de-cable the derailleur, and back both screws all the way out.

Then the derailleur spring will bring the chain all the way to the highest gear (smallest cassette cog), and since you backed the limit screw out, the chain will want to rub against the frame stays.

Use your fingers to push the derailleur up into a lower gear and then turn the limit screw for the outside limit one full turn. Repeat this until without using your hand to guide the derailleur the chain rests in the highest gear without needing any force, but also doesn't rub against the frame stay.

Then use your hand to push the derailleur all the way to the lowest gear (largest cassette cog) and try to get the chain to fall between the cassette and the wheel spokes. If it can fall over the inside of the gear and into the spokes then turn the limit screw for the inside limit one full turn. Repeat until the chain can reach the lowest gear without using excessive force, but cannot fall off the cog toward the spokes.

Add some lock tight to both limit screws so that you don't have to adjust them again, and you are done!

Now just reattach the rear derailleur cable and adjust the tension if you need to.

Could you imagine living in a world where you had to start every business relationship by only making extremely small "beta test" transactions, be it a trip to Target to opening an account at your local credit union. Like, on your first trip to Costco, you only bought a box of gum because you couldn't ever be sure they wouldn't somehow completely fuck you over and if they did fuck you over the societal response would always be "LOL too bad, so sad.... shouldn't have trusted them!!!"

I dunno about anybody else, but that really isn't the world I would want to live in.

There is value, substantial value, to trust others and when that trust fails, having a solid legal system to back you up. If you cannot trust anybody but yourself, every transaction you make becomes significantly more expensive.
meeh number of comments to process do not really make any difference for bots.
Unlicensed, but not unregulated. There are very detailed limitations on transmitter/antenna powers in those areas, limitations that are very country-specific. The rules for laser, where they exist, are more akin to "don't burn our people's eyes".
Well I don't think you'd collect waste at the individual level, that seems absurdly arduous. Most developed nations already have an excellent pipeline (literally) for collecting and centralizing human waste. It would probably make more sense to collect it somewhere along the line at sewage treatment facilities. There would still be many other challenges with that.
No, the biggest thing we're missing in the fight against 2-party system is an actual representative voting scheme.

A first-past-the-post [1] voting scheme will always result in 2 parties (assuming it doesn't collapse into a single-party autocracy) due to the spoiler [2] 3rd party vote problem.

It's not psychology but basic probability math and game theory.

Why is not fixed? Because this is the cheapest way for the moneyed elite to both a) wield power, and b) prevent that power from getting concentrated (which could result in a powerful dictator who doesn't listen to them).

I can't speak to every hiring manager, but I definitely read cover letters and value non-generic ones. (And in fact my job ad instructs you to include one. So I still look at resumes that come in without one, but it doesn't speak well to your attention to detail.)

The tone doesn't matter that much, but I would avoid the extremes of very informal or very formal. It should be the first thing that I read, so if you're applying by email it should be the body of the email.

A cover letter is an opportunity for you to tell me why you're interested in this job/company specifically and to highlight things that might not be readily apparent by reading your resume. Some of the best cover letters call out specific achievements that are relevant to the job you're applying for, or preemptively address concerns that someone reading only your resume might have. Even just including enough information to show that you did some research on the job/company before applying already puts you above most cover letters. A generic cover letter makes me wonder if you're just applying to every job ad.
The worst part is they didn't even have to include this question. Including it and then giving such a bullshit non-answer is like a slap on the reader's face.
What he's describing is that the overwhelmingly vast majority of people (who are supposed to replace fiat with ctypto in the future) reside on one end of the pole. The end with all the real-life, non-ideologically-constrained usability.

Most of the mass in plants comes from the air, and most of the mass of soil loss is from erosion and runoff, so this wouldn't avert loss, just reconnect mass flows for the process for natural soil generation, while not altering the processes that lead to the unnatural rates of loss in the first place.

You should never 'apply for a job' in the traditional sense unless it is an hourly job at a mall or something like that.

For professional jobs, the pattern is as follows:

1. Locate professionals at the company you would like to work at.

2. Email them through a friend if that is possible, and if not, cold email them and say you are interested in learning more about XYZ company. Ask if they can grab a coffee or do a quick call.

3. During the coffee, ask them good questions to learn more and if you think you would still be interested, ask them if they have any advice on how to apply.

4. Do their advice, which typically means giving them just your resume and having them insert you in to the HR recruiting process.

Any other strategy is a gigantic waste of time.

Your quote refers to idividuating information that is, in the mind of the interviewer, unambiguous and certain. To take the example from the paper, "the person was seen punching an adult". I don't know if you've ever interviewed someone for a job, but I wish the information I gather from interviews were at the same time unambiguous, relevant, and certain.

The very same paper is littered with examples of cases in which stereotypes affect the judgement of people when your clause ("only applies to people that you are completely unconnected to and have never interacted with") doesn't apply. So I'm not sure if you're being intellectually honest, or cherry-picking the most extreme circumstances examined in the paper and generalizing them. Just one of a multitude of examples cited:

> a child from a high socioeconomic background who displayed a mixed performance on an ability test was rated as higher in ability than a child from a low socioeconomic background with the same performance (p. 293, citing two different studies)

So if you honestly believe that the stereotypes associated with gipsies cannot impact their lifetime opportunities in a harmful way, please do read in detail the Kunda & Thagard paper. And by all means believe the paper.
It's controversial. It could be good or bad, depending on your culture and opinions.
