> "Schools are upside down. Students should be teaching, and teachers at all levels should learn no matter how much they resist doing so."

i was musing about this the other day... split the day between teaching and learning (probably alternating by hour): teach the grade below you and learn from the grade above you. teachers would mainly guide the teachers and set the agenda. the student teachers can grade papers, with adult teachers spot checking their grading.

> "...the internal market economy..."

some chinese companies, notably haier, used some form of the internal market economy to become multinational behemoths. your group would only be successful if you added enough value to the internal value chain that another group would "buy" your product, with the external customer as the final arbiter in the chain.

problem definition implicitly frames a situation and thereby narrows the window of possible solutions. i've learned to look for these kinds of solutions because those kinds of solutions tend to be the most effective. when you want to stop a bad habit, don't focus on the stopping. create a world where the habit is unnecessary.
No, the body does not use the same amount of oxygen, as the amount of CO2 it exhales.

The amount of oxygen used is way higher.

A person consumes 19 cubic feet of oxygen a day.

Edit: I looked at the composition of inhaled and exhaled air, and now I realize the reason O2 is being taken out of the air in higher amounts than CO2 is introduced, is that the exhaled amount of carbon dioxide is not the total amount of carbon dioxide that has been created in the body.

When the CO2 in the room gets higher, more CO2 is actually taken up again from the room back into the human body, with the exhale rate staying relatively constant. Or in other words, a significant part of the increase in CO2 in the system human <-> room is actually in the human, not in the room. The room measurement thus covers only a part of the CO2 being produced in total, and only the unknown total amount of CO2 produced reflects the totality of O2 being used up.

This means a change of 1000 ppm of CO2 in the air will mean a higher amount of oxygen has been used up.

Quite the opposite. Only around the modern era (20th century and onwards) have had the ability to take total or near total command of the economy. Throughout the majority of history, states have only been able to tax and mobilize single digit percentages of the society's GDP. Historical estimates are rough, but good enough to appreciate the stark disparity between modern governments that often mobilize 25-50% of the society's GDP.

It couldn't be further from the case that command economies are the default state. They're a relatively possibility in the scope of human civilization.

Nietzsche touched somewhat on the paradox of tolerance with the last men; a society in which everyone is pacifist, living comfortable. Conflict and challenges have been eliminated. Individuals are tired of life, take no risks. A life where no intolerant people exist.

Suffering is necessary for life, he argues ("That which does not kill me makes me stronger") and that likely includes the tolerance we extend to others.

How much suffering should society endure by intolerant members to ensure it grows into something better? A difficult question (there is probably no answer).

IMO some intolerant individuals, must exist in society for society to progress and grow, to drive progress for the sake of leaving the intolerant behind and to show us a mirror of our worst selves and a starting line we must grow distant to.

> is it true?

In my experience (hired 10 engineers), yes.

It's technically easy to fire people, but it's emotionally draining on the team and on the manager in particular. Every time you fire someone, the team's morale takes a hit, and if you were firing people often, folks would begin to feel insecure and you'd struggle to keep good engineers.

Smart, good people want to work with other smart, good people. If you're constantly bringing in bad hires (even if you later fire them) then your good engineers will get fed up and leave.

The net value of a bad hire can easily be negative, if you consider the high onboarding costs to get a new engineer ramped up and trained. (Of course, the very best engineers basically sit down and start coding as well as your existing good engineers, but these true outliers are by definition uncommon). Not to mention the cost of the bugs and rework that bad hires produce.

If you use a recruiter, you're typically paying a large fee that you can get refunded after N months (details vary, 3 seems common), so you'd have to be making your assessment in the first N months; that's a lot better than trying to make an opinion on the first day, so if all of the above wasn't true, in the abstract, it would be great to be able to hire aggressively and fire likewise. However, good engineers balk at the concept of a "trial hire"; understandably, as personally I'd refuse to work somewhere that didn't have conviction that they wanted to keep me.

I imagine the relative significance of these points varies between companies and stages; all of these points are from early-stage (<25 person company) startup life; YMMV.

> (something you won’t get from a whiteboarding challenge).

I agree with this point, though I think it's orthogonal to the question of false positive vs. false negative cost optimization.

Eventually we go from a black-and-white rules (hell, even Go is kind of a negotiation), to using economics as a tool to determine what option satisfies all parties. I don't think humans have solved that yet, but like radiology, perhaps AI can make better compromises?
Money printing is in effect a regressive tax. Inflation is effectively a flat tax, it wipes out X% of people's savings regardless of whether they are in the bottom 10% of the income distribution or to 10%.

In fact, it might even behave like an inverse tax, since the wealthy will be the first to move their savings out of dollars while most everyday people will be stuck with their savings becoming worthless.

Five Myths About the 47 Percent

With every similar news I feel dumb. Because my parents and my grandparents used to say same things. It was easy to dismiss all the advice as grumbling, but I really should refresh air before sleeping, humidify air in heating season, eat more vegetables... etc. etc.
AI agents need environments with a complexity similar to that of our own in order to understand, and a goal to optimise on (humans have 'survival' as the goal). The missing link is that intelligence is dependent on environment and AI agents don't have rich enough environments yet, or a long enough evolution. The level of understanding is related to the complexity of the environment.

But that can be fixed in simulation. That's why most RL research (RL being the closest branch to AGI) is centered on games. Games are simple environments we can provide to the AI agents today. In the future I don't see why a virtual environment could not be realistic, and AI agents able to 'understand'.

No game (or any large software project) is ever bug-free, but the standards were higher than they are now. Fallout 76 was literally unplayable on launch-a fairly early mainline quest was broken, so it wasn't possible to reach the endgame. Was civ unbeatable on release? Sure, ghandi was bugged, but that was entertaining enough they kept the bug in the sequels.
Most of the top employers in the market have similar types of interviews so you have to study anyway unless you want to rule out all of them and any time spent preparing for such interviews amortizes across all of them. Meanwhile, a take-home test is almost always a one-off and takes much longer on a marginal basis and rarely is even used to make the final decision - every time I've done a take-home, I've also had to go through the full interview loop.

Also, "an hour of my time programming a solution to a problem" is likely not an actual work-sample/take-home - it's likely a replacement for a phone-screen that doesn't require an engineer to conduct, thus can be given to many more people to keep the top of the funnel large. The only time I've done a real take-home in less than 10 hours, it was rejected for not being polished enough.
The foreign policy of the US, including all invasions, death squads, oppressive trade deals supporting open slave labor (sometimes to death), is primarily to support the business interests of the upper class of the united states. The petite bourgeois’s increased “quality of life” (which is an incredibly misleading term) is a byproduct of the largest wealth redistribution in history, at american gunpoint.

So, it’s incredibly disingenuous to reduce all alternatives to capitalism to murder when american capitalism is objectively morally broke.
> Being intolerant of intolerance does not necessitate being intolerant of the intolerant.

How does it not? At some point things come into conflict. As an example, religious views that condemn homosexuality as evil. Adherents of those views will, given the power, happily prevent gay marriage by force, or much worse. If you want to defend tolerance, you will have to stop them from doing that, also by force (political or otherwise). There is no way out of that.
> Computers haven’t to date ever done anything on their own, what reason is there to think they ever will?

Interestingly, people that spend a lot of time studying their own brain by meditating are usually very confident that what most people call "free will" does not exist - is merely an illusion.

Not to mention that physics tells us that we should be simul-able, after all physics knows only about deterministic and random processes.
Ah no!
If you want good, thoughtful news I suggest the Atlantic or the New Yorker (society, culture, politics), Talking Points Memo (politics only), or Propublica (no breaking news, just investigative). All of those four are controlled by journalists and have a more slow-news, news analysis focus. Add a local newspaper, just not one that is owned by a hedge fund or rightwing billionaire.

If you want to listen to audio, there are a lot of great podcasts, many from the above publications. (People in the rigthwing media bubble will complain that the above four pubs are liberal, but frankly: reality has a liberal bias in 2019, and all the above are truth-first, and thus VERY different from rightwing pubs like WSJ, Fox, Daily Caller, etc.)

As for NPR: it is really a terrible example of our current 'both sides', conservative-influenced media. NPR sounds fair, but the NPR news production is strongly controlled by its individual member stations. Because of that station control, NPR is highly susceptible to whining from the right, and so they end up presenting "both sides" of many issues, even when only one is true. It's sad. (Example: NPR refused to use the word "lie" to refer to DJT's statements even as late as Dec 2016, when the NYT had come out with a usage of "lie" to great hoopla in Oct/Nov 2016). The NYT is better than NPR, except for NYT politics coverage: don't read its politics coverage and if you can, skip its headlines. For some reason NYT editors and politics reporters are strong believers in the both sides, fact-second religion.

> i was musing about this the other day... split the day between teaching and learning (probably alternating by hour): teach the grade below you and learn from the grade above you. teachers would mainly guide the teachers and set the agenda. the student teachers can grade papers, with adult teachers spot checking their grading.

As a teacher, I think this is an interesting proposal. It definitely would help a lot, and the ones teaching would get a firmer grasp on the material without a doubt. I wonder if it could be integrated into something like Sal Kahn's model, however. Say, kids watch lectures at home, and then kids in the higher class help them work through problems, with teacher guidance to explain in more depth for curious students and to help work through problems.

There's a few issues I see with this, however, the main one being timing. There's only so many hours in a day, and if kids are going to both learn and teach, we'll have to cut down on something in the high school curriculum. Sadly, I fear this would mostly be electives or humanities classes, two things which are still needed. The other issue would be what to do with final year students. Would they only teach, or would they still need learning too? Ideally, they could get an internship, but who knows how that would really work, especially in rural areas/areas without many job opportunities.

The article or the whole technique that sounds a bit para-scientific about normalizing the heart beat is dead wrong. The vagus nerve actually increases what is called heart rate variability which is a very good thing and even a longevity/cardiac health marker.

These days I think of "cron" as more of a type than an actual implementation. When somebody says, "I need a cron job" my answer these days would never be, "ssh into www1 and add it to the crontab." It would be, "create a CronJob type in Kubernetes."

But I agree and concede, a user with zero back-end experience will just google "cron" which will take them to a crontab example, so they will likely be mislead into the anti-pattern, as you said.

Static typing doesn’t reduce bug density, this is no news, just a risk compensation principle at work.

But there’s another factor: static typing creates a nice puzzle for you to solve instead of solving the actual problem. You solve the puzzle and feel nice, you show the solution to management later and they feel nice to because it’s all neat and hierarchical. Then you write majority of the code that doesn’t neatly fit the puzzle’s constrains, then new feature requests/requirements come in and after a time the puzzle needs to be solved again. And so the wheel turns.

What people usually mean when they talk about static typing is a language to specify promises and requirements. To my knowledge that language has not yet been successfully reduced to mostly static and rigid annotations that are useful in dealing with changes to the software itself.
I would like to claim I thought similarly, but that’s such a milquetoast claim I don’t think anyone would remember. Chess is simply a search problem, trivially scalable if you just throw cash at the problem.
Reminds me of the story that Paul Allen recounted about Bill Gates going off to Harvard rather pumped up about his abilities relating to math (Gates has said he considered wanting to teach math as a profession when he was in high school) and then realizing he wasn't good enough at it to keep up with the elite math students there. That to keep up with them you'd need to be among the best in the field and even if he was good, he wasn't math-genius level good.
