jschwartzi··on Nuclear technology’s role in the world’s energy supply is shrinking
The problem in the PNW is that these lakes are bad habitat for our native salmon. The more dams we make, the less habitat there is for the salmon. It's not a matter of "oh we just don't like them on principal." Rather, they tore down the dam in Elwha because it eliminated what was previously a thriving spawning ground and replaced it with a silty lake full of invasive species.

Everything is interconnected, and it's a really typical technocratic attitude to say that it's fine in isolation. "Who gives a shit? It's just a bunch of fish." Analytical people eschew context. Analysis is about reducing everything to components. And guess what -- it has led us astray here.

It turns out in the PNW that salmon are a major part of the food chain for a lot of animals, and our hydropower efforts are suppressing that food chain. It's also making it really hard to find enough salmon to fish for ourselves.

You'll see similar problems with the Colorado River. The Hoover Dam has basically destroyed all the downstream ecosystems that relied on the water to create their living conditions. It's an ecological disaster in slow motion.

jschwartzi··on When did writing in major newspapers become so bad?
The reading level is probably the best gauge for whether an average person will understand what you're saying. If it's reading level 14, that means post high school. Most people in the US graduate from high school with an 8th or 9th grade reading level. So a piece with a 14th-grade reading level will be completely beyond them.
jschwartzi··on What’s Wrong with “Multiplication Is Repeated Addition”? (2008)
I think the heart of the issue is whether it's more useful to teach children how to multiply two abstract numbers together as a kind of "mathematical procedure" that they need to memorize, or whether it's more useful to teach children that if they measure two sides of a square with a measuring tape, they can "multiply" the measurement and that the result is now in "square inches" rather than regular inches. And the schism is that some people believe that procedural memorization is useful because after 20+ years of education they've gotten through the good part, and other people believe that the procedural memorization does kids a disservice by divorcing mathematical thinking from the concrete world entirely.
jschwartzi··on What’s Wrong with “Multiplication Is Repeated Addition”? (2008)
Except this isn't a pedantic falsehood. Multiplication has nothing to do with addition and at some point we have to stop teaching students that it's related. Understanding ratio is key to understanding a lot of the physical sciences and you can build a really good intuitive understanding of a lot of simple physical concepts if you can just do dimensional analysis. But if you think of multiplication and division as a kind of addition then it all breaks down and you can't reason about much at all with those tools. In fact you can't even get over the hurdle of doing dimensional analysis in chemistry or physics in the first place. It doesn't make any sense. And you'll have been set up to fail by your teachers.

They're not saying "we should be teaching kindergarteners using Euclid" they're suggesting that focusing on the process of doing multiplication hides a lot of very useful insights about why someone would do multiplication in the first place.

The biggest problem with math as it was taught to me in grade school is that it was focused on rote memorization of a procedure. Which is fine if you need to calculate how long to cut 2x4s or stair stringers but it doesn't help you at all if you need to understand why that works the way it does. And god help you if nobody ever shows you the exact method of calculation for those two things in the first place. You're set up to fail if you only focus on process.

jschwartzi··on Bash_unit – bash unit testing framework
Or you literally just need to run a sequence of commands to create some stuff in the filesystem without doing any text processing whatsoever, which is my use case for the three or four large-ish BASH scripts I've written professionally. Make was totally inappropriate in that case because I would have had to enumerate a lot of intermediate files and would have wound up with a parallelizable series of mini-scripts that would need to run serially to work correctly. And Python would ultimately turn into a DSL that looks almost exactly like BASH because the problem domain is "run a bunch of commands in sequence" which is what BASH is designed to do.
jschwartzi··on On the Experience of Being Poor-Ish, for People Who Aren't
The employees who would be jealous are operating with a different definition of "fair." The common definition is that everyone gets the same thing, but a more humane definition is that everyone gets what they need. And if you switch from the former to the latter then the owner's decision becomes very fair. Everyone benefits from having the specialist focused on work. And the specialist gets what he needs too.

luck is just another word for other people.
jschwartzi··on Judge in Google case disturbed that 'incognito' users are tracked
Firefox sets the Do-Not-Track flag when you're browsing in Incognito mode. I think it's only Chrome that doesn't provide that information. So it's entirely possible for your analytics trackers to not forward those analytics on for users who are in Incognito mode if those users are using a browser like Firefox.
jschwartzi··on Semiconductors Demand 30% Above Supply, 20% Year-on-Year Growth
That's almost as much soup as I eat in a year.
jschwartzi··on The trial of a child soldier who became a brutal rebel commander
I must have misread OP, because it sounded like they were suggesting Ongwen be sent back to try to rehabilitate other fighters.
jschwartzi··on Noise pollution hurts the heart
My willingness to accept your loud muffler bottoms out at $100,000 per 100 mS per decibel over 40 dB. If you're willing to put up $4-5 million every time you drive by my house, I'm willing to let you pay me for the privilege of ruining my sleep for your stupid car.
jschwartzi··on The trial of a child soldier who became a brutal rebel commander
Even if that were possible, Ongwen may be too damaged to be very effective at such a "punishment." And it would be very cruel to expose him to the same environment which traumatized him enough to make him into a brutal commander.
jschwartzi··on Mars becomes the 2nd planet that has more computers running Linux than Windows
From what I understand they use the Mars Reconnaissance Orbiter to do exactly that when the rover loses direct line of sight to Earth.
jschwartzi··on Share of U.S. workers holding multiple jobs is rising
The other component is decoupling health care and dental insurance from employment. Because that's a far bigger problem than retirement. A lot of people lost their jobs last year and suddenly had to pay full price on their insurance to keep going to their doctor.

The whole insurance system in the US is best described as a real-life re-enactment of The Trial by Franz Kafka.

jschwartzi··on House Republicans propose nationwide ban on municipal broadband networks
We don't even have to go to the Department of Licensing to renew anything here. You can do it all online. The only time you'd need to go anywhere is to apply for a new license or to update your photo or physical characteristics. They even take credit cards.

Government only sucks if you accept it sucking as a foregone conclusion. Hold government accountable and it will stop sucking.

jschwartzi··on House Republicans propose nationwide ban on municipal broadband networks
And in the former case, the people lose.
jschwartzi··on California’s affordable housing problem is really a national one
There's a big difference between a power substation and an oil refinery. And depending on how that substation was built and the decisions made it can really negatively impact someone's use of their property. In my case the substation our PUD built across the street involved denuding the entire area of trees. This is mainly a problem because the freeway is right behind the trees they removed. So removing the trees made our front yard very difficult to inhabit for long periods of time because it's so loud. I'm not the only person affected either. And I wouldn't object had they built any kind of sound isolation.

I wouldn't object to an oil refinery either if they can guarantee they won't suddenly explode and kill me while I sleep.

The fact remains that we all have to be good neighbors to each other, and that cuts both ways.

jschwartzi··on An experiment in giving cash to recently homeless people [video]
I don't understand this argument. People are extremely good at inventing purposes for themselves within their context. If you give people a livable but meager amount of money it's true some people will fritter their life away for a while. But a significant portion of the people on UBI will invent a niche for themselves. The ennui itself is a motivator for people to find something useful to do.

The reason people have a problem with UBI is that we have a tendency to equate our moral- or self-worth with our economic productivity. If you don't draw a salary for services rendered it seems like you're not worth anything.

There are tons of occupations people can have that generate no significant monetary value. Volunteering and taking care of children are two such occupations. These both have tons of value to society. So it's clear to me that economic output is not the only source of value. Maybe it's time for society to recognize the value of those non-economic occupations by paying people for them?

jschwartzi··on Killer Whales: 'Transient' Orcas Are Thriving
I'm actually working on a side project called Whalebernetes which will allow you to orchestrate groups of virtual Orcas to perform tasks like gather salmon or seals. These Orca groups, or Pods can then be moved between various Oceans as-needed depending on the needs of your business.
jschwartzi··on The Miyawaki Method: A Better Way to Build Forests? (2019)
> Birds will drop seeds, and those seeds will germinate beneath the pioneer canopy, letting the larger species come through and eventually replace the pioneer species.

FYI This can actually be a huge problem if you live in Washington State, because Himalayan Blackberry spreads through bird droppings. You have to aggressively weed it or it will choke out everything else in the area within a matter of years, including saplings, mature brush, grass, native blackberry, and other invasives like Scotch Broom.

jschwartzi··on Multiple Beverly Hills PD officers now weaponizing copyright against streaming
If that's the case, the cop can arrest them for harassment and use the video as evidence.
jschwartzi··on Multiple Beverly Hills PD officers now weaponizing copyright against streaming
It's disingenuous to say we, as the public, have no interest in what the police do while discharging their duties. It is a public office, after all.

And I think the activities of the police should be scrutinized heavily because they have an incredible amount of power and are accorded a very wide latitude. The police are the only people who can legally shoot you and not be tried. They can arrest you and throw you in jail. They can charge you with crimes, invade your house, and smear your reputation with the public. A police officer with a vendetta can absolutely ruin your life if not outright take it from you.

So yes, I think it should be okay for people to video the police going about their business.

jschwartzi··on LinkedIn’s Alternate Universe
Okay.
jschwartzi··on LinkedIn’s Alternate Universe
I'd be interested in a tool like that. I try not to look at the names of applicants and drop anyone who supplies a headshot but it would be nice to have that information filtered out.

Yes, several applicants supplied a headshot for the last engineering role I hired for.

jschwartzi··on Is it better to use cat, dd, pv or another procedure to copy a CD/DVD? (2015)
Except the whole point of the wrapper is to protect people who are ignorant of alternatives from overwriting their main system drive by carelessly typing /dev/sda when they mean /dev/sdb on their local system. So making a new command and socializing it doesn't actually improve the situation at all.
jschwartzi··on Why banning 'harmful' online speech is a slippery slope
What narrative?
jschwartzi··on Why banning 'harmful' online speech is a slippery slope
Slippery slope is actually a kind of logical fallacy.

The author needs to prove that suppressing fascist speech actually has some kind of negative effect or that it leads to other kinds of speech being suppressed. You have to look at intent here to see whether the suppression will lead to a slippery slope. In this case, it's not about suppressing speech it's about removing people who act in bad faith.

On this forum we often suppress the speech of people we disagree with. And people get banned too. If we subscribe to the author's point of view, then why do we have moderation or shadowbanning in the first place?

jschwartzi··on FTC Settlement with Fertility-Tracking App for Facebook/Google SDK Data Sharing
Having done a lot of research myself, there's a ton of folksy "tricks" online but precious little real research information available. A lot of the "tips" boil down to "be young and healthy" and "don't be old and unhealthy."

I've read some peer reviewed research as well but most of that is focused on outcomes and genetic testing of IVF embryos rather than natural fertilization. I get the impression that fertility isn't something that's well-studied outside of really generic health indicators like weight and age. And a lot of fertility information seems to focus on ages 20 to 35. They seem to assume that after that age you've given up on starting a family or that you already have one.

jschwartzi··on FTC Settlement with Fertility-Tracking App for Facebook/Google SDK Data Sharing
Yeah you can definitely sell anything to a couple who is trying to get pregnant, especially if you know they've been trying for a few months without success.
jschwartzi··on BeagleV – An affordable RISC-V computer designed to run Linux
Yeah as someone who has deployed SD-based and eMMC-based systems in industrial spaces, SD cards are hot garbage compared to eMMC and I would strongly recommend not using them in anything that needs to be reliable.
