Tech enabled the horrors of WWI and II, tech directly enabled the Holocast -- IBM built special computers to help the Nazi's more effectively round up the Jews.

Tech also gave us vaccines and indoor plumbing and the clothes I am wearing.

It's the morals and courage to live by those morals which creates good. Progress is by definition towards a goal. If that goal is say

> to form a more perfect Union, establish Justice, insure domestic Tranquility, provide for the common defence, promote the general Welfare, and secure the Blessings of Liberty to ourselves and our Posterity

and ensure our basic inherent (not government-given) rights to

> life, liberty, and pursuit of happiness

then all good.

If it is to enrich me at the cost of thee, create a surveillance state that rounds up and kills undesirables at scale, destroys our basic inherent rights, then tech not good

Just imagine the incalculable wealth if you could store the energy of the sun in, say, plants, which would release the fresh mist during the night, build the health of the soil, and enable mobile life forms to carry the energy around to move it to other locations.

North Africa was the breadbasket of Rome, filled with life and water. Then we turned it into a desert.

did similar work at similar scale to srean.

Assume you have signal from one IoT device, say a sensor reading. Anomalies are sudden changes in the value of the signal. Define sudden (using the time delta between observations and your other domain knowledge); let's say the sensor reports 1x/second and sudden means 1-3 minutes.

Simple options: rolling mean last 3 values/rolling mean last 60 values. If this value is over a threshold, alert

Say the readings are normally distributed, or they can be detrended/made normal via a simple 1 or 2 stage AR/MA model. Apply the https://en.wikipedia.org/wiki/Western_Electric_rules to detect anomalies.

Complexer but still simple options. Say you have IoT sensors over a larger area, and an anomaly is one sensor which is higher than others. Run roughly the same analysis as above, but on the correlation matrix of all the sensors. Look for rapidly changing correlations.

example: temperature detectors in each room of your house, and your kid opens the front door to go play in the snow. The entry hall cools down while the rest of the house's temp stays roughly stable. You can picture what that does to the correlation matrix.

you missed the "almost as" in your first sentence.

also, we didn't define "good".

> R is perhaps the closest, because it has data.frame as a 'first class citizen', but most people don't seem to use it, and use e.g. tibbles from dplyr instead.

You're forgetting R's data.table, https://cran.r-project.org/web/packages/data.table/vignettes...,

which is amazing. Tibbles only wins because they fought the docs/onboarding battle better, and dplyr ended up getting industry buy-in.

Curious if we could test/compare (popluation-level) memory skills before/after writing was introduced to the population.

I want to say "I remember things better when I write them down", and because I think I'm a smart person I think my memory is good.

I don't know how well I'd remember things if I'd spent a large portion of my life building memorization skills. Maybe I could be 100x better at memory if I exercised it more?

who said anything about finite?

After the [revolutionary] war, there were calls for Washington to claim formal political power. Indeed, seven months after the victory at Yorktown, one of his officers suggested what many thought only reasonable in the context of the 18th century: that America should establish a monarchy and that Washington should become king. A shocked Washington immediately rejected the offer out of hand as both inappropriate and dishonorable, and demanded the topic never be raised again.

"We the People of the United States, in Order to

- form a more perfect Union,

- establish Justice,

- insure domestic Tranquility,

- provide for the common defence,

- promote the general Welfare, and

- secure the Blessings of Liberty to ourselves and our Posterity,

do ordain and establish this Constitution for the United States of America."

Yeah, seems like a good idea to me

and one more time, sorry, you triggered a rant.

if you can't count on your troops to be disciplined enough to follow your rules of engagement, how can you count on their discipline to follow your other orders? If you cannot show them that you are also disciplined, how do you expect them to maintain their respect for you as a leader?

If you don't have honor, what are you fighting for? Troop moral is what wins wars.

what's worse than death? Not having anything worth living for.

very very few people find honor in being the most evil person. And those few who do make very bad leaders; you either avoid having them in your armed forces or you limit their impact.

If one of your squadmates is an "I'll do anything to win" person, how can you trust them not to ditch you if that is their best survival option? Prisoner's dilema situations are common in battle

I encourage you to visit a US military cemetery. You will sometimes see shrines to the military virtues. Courage, honor, pride, family, discipline all rank pretty high.

To address your concern-- if two people are fighting and one thinks "I won't hit below the belt" that person is at a tactical disadvantage. Even worse if they think the other side has also agreed to that rule.

So in that sense you are absolutely correct.

But I invite you to think bigger. If one side lays siege to another side's city, and offers terms of surrender, the city needs to believe that the terms will be honored otherwise they don't surrender.

Which is a large part of European history during the period from the middle ages up until Napoleon figured out how to use artillery, i.e. hundreds of years of examples where "fighting honorably" was the winning strategy.

How does WWII strike you?

Notice that Germany and Japan are now strong allies.

Also notice that many people think the cause of WWII was that the WWI surrender forced unsustainable terms on Germany thus fueling the resentment that lead to WWII.

Friend, I have respect to where you are coming from, and ask you to please think a little longer term.

You don't prioritize the well-being of the other side, but you do want to avoid radicalizing them. The more reasons they have to surrender, the more likely they are to surrender, thus ending the conflict sooner AND keeping the end conditions one they are comfortable living under.

If instead they feel they are in a fight to the death, then you have a much tougher battle on your hand because they will fight to the death. You'll still win (maybe) but it's going to cost you in personelle and time and money.

Next aspect. Moral of your troops. Everyone wants to be a hero, very few people join the military because they want to kill. And those that are in it to kill tend to be toxic leaders which is really bad for the rest of the team.

"Rules of war"/"rules of engagement" are methods that allow your troops to maintain their humanity and sense of purpose under horrific situations. You give up that and you are now undercutting the fighting power of your own forces.

The military did not come up with these ideas to make themselves weak. They came up with them and enforced them because they are the source of strength.

Concur. Lack of empathy is the curse of our age and the destruction of our society.

> Ultimately, capitalism is not necessarily at odds with providing efficient high quality healthcare.

Um, yes it is?

First off, there is tension between "efficient" and "high quality". High quality in an environment with peaky demand requires over-resourcing during periods of lower demand, which is inefficient. The best way to resource for peaky demand curves is to run at 60-80% usage (i.e. 20-40% idle).

Health care has peaky demand curves. PE is going to optimize on efficiency therefore degrading peak demand performance, which is when quality matters the most.

Second, capitalism optimizes resources to maximize value capture. That's great when value capture is tied closely to value delivery, like you want a hamburger and you get a hamburger.

Not when value capture is diffusely tied to value delivery. You want a stable market economy with rule of law to protect your property and your contracts. While without this, nothing you own has any worth (making it the most valuable thing possible), the value of this is rarely delivered to you in discrete chunks.

> And then when times are bad, small organizations are the first to die, because they lack the economies of scale and financial reserves that allow them to weather a contraction.

Not sure it is bad times which drives this. Plenty of examples in human history of the tendency of humans to form small local support groups when times get tough.

Volunteerism has been on a massive decline my entire life, good decades and bad decades. There is some other force in our current social order which is tearing it apart.

Wait, could you remind me what war was going on when NASA took us to the moon?

Could you remind me what war was going on when the CDC eradicated malaria from the United States?

Could you remind me what war was going on when FDR build our basic social safety nets?

Broadly speaking, people have 3 ways to organize large groups: business, government, and (organized) religion. Each has strengths and weakness. To say that only one can produce social good is a bit of a stretch.

> DOGE toppled existing incentive structures, yes

> emphasising cost reduction

no.

better analogy: the majority of fouix-gras birds would prefer not to be force-fed and caged.

The people working in the bureaucracy do not have the authority to overhaul it.

> The R community should have anointed one object system

> and made tidyverse a core part of R.

Not a tidyverse fan. It doesn't scale well.

Learn data.table, which has a much more R-like interface and is fast fast fast even for large data sizes. More powerful and more expressive than pandas, and again, faster

the reason to NOT have a DSM-recognized diagnosis on your medical record is it can be used to disqualify you for things later in life.

And we cannot predict all of these future changes, either in our interests and/or the law.

Assume you viewpoint is correct. How is this different from so many tech bros?

The person is doing something physically and technically challenging. Perfect HN material.

Would love to dive into how he built the paddleboard, etc.
