Nobody needs anything. You didn't need to write your comment. And neither did I have to write this one. That's terrible criteria to judge anything, if it even means anything sensible at all.
I have worked for a company that spent a multiple of your amount in a single day on a PPC advertising.

The fact that it works for you doesn’t mean that if that industry wasn’t as monopolised and unregulated you wouldn’t pay 1/10th of what you paid for the same.
It doesn’t matter.

People grow up, they have to make money one way or another.

Very few people feel at ease working on a commune. Even then they have to dip their toes into regular society.

Probably the Amish and others like them actualize the purported lifestyle better than the supposed hippies.
The mistake is assuming "=" is a statement of fact (as in mathematics), rather than a request for assignment (as in programming).

Depending on which programming language you're using, "foo = bar" can mean either "make foo now equal to what bar is" or "is foo equal to bar now?". Neither one is the same as in mathematics, which is "foo is categorically equal to bar".

Consider:

foo = 1
bar = 2
foo = bar

In mathematics, this would be a logical contradiction, and either you'd realize you made a mistake, or you'd jump back to the step where you said "now assume ..." and say "now we've proven this can't be true".

In programming, this is perfectly valid, and means "ok, ignore what I wrote just 2 lines ago, and now make foo equal to 2, also".

You say you think it means "the LH var equals the RH value assigned to it", but you don't say what you think it means to assign to the literal 1.
tanh(Ax+b) is simple, but the dataset it's supposed to work on is not easily summarised. I think that's the huge difference. The guys doing "sugar molecule" studies make progress by taking much simpler datasets, like random points.

Naiver-Stokes is much simpler because it operates by itself. Of course turbulence is hard but even there we usually care about its coarse features, we'd be content to throw away almost all the information provided the calculation of the wing's lift works out OK.
This seems like it could be true, but is against my intuition. It could be that in 1900 things that killed people killed them before brain activity was significant to have an effect. But as health results improved, brain activity ended up being a bigger factor on when someone died because they weren't busy dying from typhoid 25 years prior.

I'm personally of the hypothesis that in most cultures men undertake activities that end up killing them earlier in aggregate than women.
This seems like it's encouraging Google's "bring your whole self to work" policy, which is wonderful, unless your job is in a toxic environment, or otherwise draining. I dialed back my amount of self brought to work at my previous job, and found that despite my constant dissociation, I was able to function better both at home and in the office.

I'm not recommending that strategy, but it can make a difference for someone in a position they're working on leaving.

Frustum culling is completely unrelated to scheduling. It’s just a technique for avoiding spending processing or rendering time on things that can’t be seen by the camera. It existed before games were multithreaded, during the time when they typically had a single main loop.

Games are not using complex scheduling and multithreading to achieve acceptable performance updating 2000 entities. You can achieve that easily on a single thread by laying your data out to take advantage of locality of reference and the CPU cache.

Sure, calculus can unlock more pure mathematical concepts than statistics. But so can graph theory, number theory, set theory and abstract algebra.

The second point you raise, that calculus has so many applications in physics, is honestly the real reason calculus dominates high school mathematics post algebra classes. 50-60 years ago an engineer mostly worked with mechanical and electrical concepts, not anything in computer science. Today, we have highly trained engineers who work exclusively with other branches than analysis. Just because you are an advanced student does not mean that all the calculus served in high school will serve you better than any other mathematical branch.

You don’t have to know that much calculus to grasp what a probability distribution is, or where the tables come from. Do you know what a limit is? Great, then we can explain a continuous distribution as soon as you grasp a discrete distribution. Areas are also something you probably can understand. Would it be cool to derive the tables by doing integrals? Sure. Do you need to in order to understand variance, significance, estimation of distributions, correlation and more? No.

I would be willing to let those who are more interested choose calculus, but I would appropriate just as much resources to let people choose the other branches of mathematics too. If you can take integral calculus, but not combinatorics, that’s a problem in today’s society. Physics and chemistry are great, but we should not let them dictate the entire math curriculum, statistics and computer science are just as important and lucrative fields for advanced students to pursue.

So, if we do have to let one mathematical branch dictate upper high school math education, let’s dethrone calculus and instead teach statistics. If I have to choose just one to give the same absurd levels of attention as calculus has been given, I think statistics will be by far the most useful to everyone, whether you’re a medical doctor, lawyer, engineer or any other highly skilled professional, statistics will probably serve you best. If for no other reason than to ask informed questions rather than just smile and nod while I explain the variance of an important business metric.
Background: A lot of older U.S Navy communication satellites used linear transponders, that are essentially general-purpose repeaters that can relay a wide range of modulation, and some could be used without any authentication. Accessing them is not difficult. VHF is accessible using modified amateur radio equipment, and UHF comsats are accessible using a simple upconverting mixer. As long as one knows the frequencies and locations of these satellites, one could scan the spectrum to identify its uplink and downlink frequency, and use them as their personal CB radios.

I run online biz and have since 1993. Today, I am watching the death of small biz online, the under-employed no longer able to increase income from online biz builds, the death of affiliate income, the spike of subscription paywalls, the growth of big tech as a result, the growth of sites as info brochures for retail brick mortar, decrease in content,all melded with large increases in labor costs, labor benefit bookkeeping and tax expenses,taxes due to nearly 2000 US jurisdictions. In time, you will have few sources for content online and it will be concentrated in gorillas, direct mail will and is increasing, retail will be big guys only, and the biggest losers will be the small guys. But blocks won't be needed then as big guys will deploy the Cobra phenomena as they can afford it. Loser: the average guy. Winner: the big guys. Ah well. More poor people. Ah well.

That piece is really bizarre and poorly written. It feels like they're trying to shoehorn a bunch of right-wing talking points into a piece about corporate boringness. This quote is laughably bad:

I unfortunately recognize several of these as being true from my five years at BigCo. Is this advice true of a (tiny) startup as well? Work should speak for itself when the survival of a company depends on it, right? I'd like to know if it's the same on the other side.

Teachers should be paid more, we all agree, but how will that solve this problem?

Are they going to spend their extra cash on mathematics lessons? In their copious free time, I presume. Just like these rich software developers spend all their extra cash on more school. I see a lot of Porsches and BMWs in my neighborhood but curiously none parked at the community college.

Are you going to hire different people, who chose to go into computers just because it paid better? I don't see many software developers who would make good elementary teachers. Or would want to try.
Shouldn’t that study focus on the distribution of types of master’s degrees, and a sub-population analysis showing which ones correlated most with teaching ability? I bet someone with a master’s in math would be better at teaching math than someone with a master’s in teaching theory. Ditto at the undergrad level.

What if stressful existance pushes for shorter lifespan with the effect of quickening the turnover of generations.

So stressful environment would speed up the evolutionary iteration of generations. While less stressful existance that has adopted to the environment would persist longer.
I'd be less generous and say outright that GitHub benefits from git being a bad tool that NEEDS an external ecosystem to make it usable.

Improving git itself goes directly against their interests.
I almost never use an alarm anymore - there's no need to, my body knows exactly when to wake up because of my circadian rhythms (that's the way humans were supposed to work after all - we didn't evolve to use alarm clocks). Of course, the time my body "knows" to wake up is almost an hour later than it should, and that's the whole problem.

The way I calculated the length of my circadian rhythm cycle wasn't by tracking the duration of my sleep, it was by tracking the exact time I naturally woke up every day. I then calculated the difference in the time I woke up each day (the daily "drift" in my sleep cycle). The median of those "drift" values turned out to be around 50 minutes, which means my sleep cycle is 24h 50m on average.

It might seem like not using an alarm clock would bias those measurements, but that's actually not the case. Even assuming the fact that I don't use an alarm clock makes me sleep in (it doesn't, but for the sake of argument), that would only effect the average time that I wake up every day, not the average drift in my sleep cycle. There are a number of other biases that would have to be accounted for if this was an actual study, but for my purposes that's accurate enough.

In reality, everybody has a different natural circadian rhythm cycle. If that cycle is close enough to 24h, then you'll have a "normal" sleep cycle. If it's long enough to cause insomnia / delayed sleep onset but your body can still "compensate" (that "compensation" mechanism is called entrainment in chronobiology), then that's called Delayed Sleep Phase Syndrome (I'm not a doctor, but that sounds like what you're describing). If your natural circadian rhythm cycle is so long that your body isn't capable of "compensating" to a 24h cycle, then that's called Non-24-Hour Sleep-Wake Disorder. Delayed Sleep Phase Syndrome is far more common than Non-24.

As for this point:

> I have to get up using alarms at times that are not related to how my body is feeling about waking up, so I don't see how tracking that would help.

I'm afraid tracking it didn't really help me at all - I simply tracked it because I was curious. My "solution" was simply to let my body do it's thing, but that's not an option for most people who have fixed work schedules or other commitments every day.
This is in the "Applied Science" channel. The idea of what is a DIY project of this guy is very high. The videos are very interesting, but expect a lot of work to reproduce it.

Also, it's interesting to notice that the project is somewhat based in an old Scientific American article. In the old times, the articles in that publication were much more technical than the current ones.
For a less snarky take, the Arctic Monkeys Album AM is undeniably a rock album but with a hint of hip-hop influence in the meter and composition and it’s an incredibly striking album. No one is rapping but just lifting the idea of rhyming in the middle of a word and rhyming schemes that span multiple bars gives a breath of fresh air to a mostly stale genre. What are music genres for if they can’t learn from each other?
There is Openbabel, which was open-sourced by the folks from Openeye in New Mexico. Anthony Nichols is quite a character, and David Weininger was even more so.

India's telecom sector on the ropes after $13B levy ruling
That's why I find anti-profit movements to be fundamentally disingenuous - the tendency to act in one's own interest is too powerful to ever be sustainably resisted by a broad movement. To preach against something one is very likely to succumb to is manipulative.

I can trust someone who admits that self-interest motivates their actions more than one who claims altruism does.
I used to think subject matter expertise helped too. If you find any evidence it does email me, I haven’t found any research to that effect.
If anyone then author feels bad about the situation. Two colegues of author seems to have no voiced opinion on this situation. The only one who is making fuss about this situation is OP.
Besides - your point is applyable to OP, because he/she is currently the only one who is in your own words "shitting" on people who are not present in this situation. How about hearing other side?
All I read is that op has no power over these matters. Yeah, op can stomp feet on the ground and gain result what op desires... eventually that would lead to the hasty leave of newcommers(and maybe even some older collegues, too) or op will have to resign or be asked to leave.
That's why it is imperative for op to sort these things out by herself/himself - what is the further goal of this communication. Is op justified to name newcommers arrogant - as maybe it is op who has not been out and has no idea about their background and experience.

I had a laugh about code - about others and mine. Like I mentioned before - these things can be only changed by changing culture of a company(or by finding a company that does have good coding standarts) and that starts by showing example of how to behave - including attitude towards importance of writing good code. If company has no such foundation and it has created environment for bad coders, then smart coders will initially nervously laugh and seeing that nothing changes will leave. Telling them to consider circumstances of bad code writing sends completelly wrong message. Pardon my expression but that is f*cked up thinking. And I am giving a very friendly advice to sort op's head first and think critically about herself/himself at first, if you and others seems to boldly rush to "help". Because all I read right now is that op thinks that op is justified to do something about others and not apply this attitude towards oneself.

Think about it this way - customers will not laugh at bad code - they will be angry, frustrated and will damage company in the end. Are you really ready to accept EA and Bethesdas blunders because you do not know circumstances of the past? Lol - this is exactly what op is asking to consider.
Bad code is a very serious matter - and forcing someone not to laugh at it is great way for a company to go down. You know what - I am all for that selfish workers like op bring down bad companies by implementing more and more absurd ideas... this seems to be working just fiiine in the end.

i was hoping for a lisp-like syntax for bash commands, but this seems to do something else.

to run a bash command i need to do:
(sh* "echo >&2 hello")

what i expected is: (echo >&2 hello)

or possibly (sh* echo >&2 hello)

if i have to quote the whole bash command, then this becomes impractical because it adds an additional quoting layer, and doesn't make bash quoting any easier.
I always found it amusing that most of my math and cs professors in college seemed to have terrible arithmetic skills. I'm sure part of it is just that it's hard to concentrate on the work when you're also narrating the process to the class, but I suspect it's also that basic arithmetic is a relatively unimportant skill in most advanced research. hiring this sort of person to teach/tutor grade school math might be like hiring a porsche engineer to repair your car. they'll get the job done, but maybe not as efficiently as your local mechanic.

The tilt of the earth relative to the sun does in fact change. That’s what the seasons are. If the earth was tilted but the tilt didn’t change over the course of the year the areas that had longer days due to being tilted towards the sun would be permanently hotter than the areas tilted away. There would be a permanent summer and winter, rather as at the equator it’s always summer.
