Two things are missing here.

The first the the null model result, if a model simply predicted the most common class, we would get accuracy of 0.649. So the CART model has increased performance by ~14%. A good start.

The second is that in many scenarios in business and especially medical scenarios, you also need to know sensitivity
(how good are we at predicting a person with diabetes does have diabetes) and specificity (how good are we at predicting a person without diabetes does NOT have it). Always calculate these metrics and a confusion matrix for binary classification.

If a simple model predicted you had low vitamin-C, a doctor in my country would simply prescribe it even if the model had terrible specificity because the treatment is harmless and cheaper than a blood test. On the other hand if a simple model predicted cancer, they would refer you a variety of scans and tests and not make a diagnosis until they were quite sure.

>Where are you getting the 0.4% coming from? Parents don't generally donate directly to public school district budgets. They donate to school PTAs and school-affiliated non-profits.

It's in the article:

>In 2018-19, PTAs and booster clubs at LAUSD schools brought in more than $36.9 million in revenues. Compared to LAUSD’s annual $9 billion operating budget, that’s not that much money

36.9 million divided by 9 billion is 0.4%.

>The article says $876 in private PTA donations are raised per year per pupil in the wealthier schools, and that is still $300 shy of what poorer schools spend overall per pupil. So the wealthier schools only make 3/4 of the spending gap.

>I know this from direct experience since I write a check annually to my kid's California public school PTA for roughly the same amount.

Ok, but even if you and every other parent does that it still doesn't make up the difference between city spending per pupil and the surrounding suburbs.

Song about Von Brun
Mostly what I've done is maintenance mode, that's where if you try to touch something it is often very complicated in secondary effects and fixes, and requires lots of tests. And additions of functionality which are bolt-on will come with 10 years of accumulated requirements around the shape of any new code and the tests.
None of the cloud providers provide the internal specifications used to autogenerate the SDKs for the languages I listed. In the case of Boto3 (the Python AWS SDK), while there are one to one generated mappings from the spec, there are also higher level constructs for the most popular services like S3 and DynamoDB and also helper functions like Waiters for asynchronous operations where you need to poll for an operation to be complete and Pagers that handle get request where the requests are being polled. Sure you could do all of this yourself. But again, “does it make the beer taste better”?

This isn’t meant to be a rah rah AWS is the bees knees. It’s just the cloud provider I know the best (and the one I work for), I’m sure knowing MS, the developer experience is just as good as AWS. I just don’t have experience with it.

> Of course it can be solved in those languages. I can also solve it in Assembly or brainfuck with enough elbow grease. What matters is speed of implementation and correctness. With the exception of Rust all these language have debilitating flaws.

What’s the old saying about it’s a poor craftsman that blames his tools? If you can’t be productive in any of the nine languages that are popular enough to be supported by the major cloud providers, does that say more about the tools or the craftsmen?

> There’s no way to do this without informed consent

Do you mean with informed consent?

Sometimes, such experiments can work even with informed consent. As in: "we will show you some pictures of your childhood, some of them may be fake" and you can still be convinced by the fake picture. Just like the placebo effect can work even when the patient knows he is given a placebo.

Hong Kong has a population density of 6,801/km^2. Singapore has a population density of 7,804/km^2.

The United States has a population density of 33.6/km^2. It turns out that this matters.

The parts of the United States that have high population densities (though still not nearly as high as Hong Kong or Singapore, in general), such as the large East Coast cities, Chicagoland, etc. already have public transportation.

It's dramatically easier to prove to a reasonable observer that Kubernetes got lifted off the ground by a bunch of folks on Google payroll than it is to prove that some GNU diehard would have inevitably sold that (silly) idea to like a zillion people if only Google didn't beat them to it.

I make these sort of observations with a certain regret: I was a kid already pushing the limits on a DOS-type machine when you could first get Slackware media: the GNU userspace has been home since before I ever woke up next to a girl.

But it's kinda over now. LLVM vs. GCC is a desperate rearguard action, the Rust people have broken the mindshare monopoly on shared libraries that was insulating `glibc` from it's better (`musl` in almost every case is better), old-timers like me are me are a bit attached to emacs and bash, but neovim and fish are pretty fucking good.

GNU and free software in general are no longer superior by virtue of Sun Microsystems leaning too hard into the JVM: they've got to work for it now, and they're getting their asses kicked.
My apologies then. It was the italicized "undue" that made me think that this was your position. I read it as "undeserving".

As for the condorcet winner, that is quite hard actually. But if we consider a weak condorcet winner (where it is true 90+% of the time), that isn't as hard. I do think simplicity, transparency, and reduced vulnerability to strategy is a worthwhile trade-off for a strong condorcet winner. But of course, this is just my personal opinion and what's the preferred optima depends a lot on personal preferences.
So that’s exactly the same thing just a slightly different wording?

Weed is scheduled by Congress, the agencies can only add substances to the schedules temporarily for "public health reasons" and there's some weed derived stuff or analogues that have been added that way but marihuana in and of itself is illegal because congress passed a law saying it's illegal: the CSA, 21 U.S. Code § 812 (c)

The CSA allows for schedules to be updated and republished annually but agencies can only recommend, the authority to remove something that's scheduled by Congress is only held by Congress.

> If you follow the logic that anything is at about half its life

I don't think that makes any sense. By that logic any currently working device should be assumed to last another $currentlifetime. My 20 year old car is not gonna last another 20 years. My 10 year old laptop won't last another 10. If my car somehow did last another 20 years, it would not then make sense to assume it would still be running in another 40.

Makes more sense to look at all objects of the same class. If 75% of laptops are dead in 10 years and 95% are dead in 15, and your laptop is 10 years old, you can infer that 5 out of 25 surviving laptops will make it another 5 years, or 20%. (These numbers completely made up, just an example.)

Me not caring about security fixes means I will continue to use those features without worrying about potential exploits. Video formats aren't going to suddenly change. Apps will still get updated, the system framework will still get updated.

In all my life, I have not once seen an android phone actually exploited. I have read about a lot of them online. But I haven't seen an exploited phone in person. Other than exploits that I have used to gain root access on devices, which all require physical access. Around 18 percent of the current android market share is made up of devices running Android 9 and earlier. Android has 3 billion active devices according to the most recent Google I/O. That's 600 million devices. I imagine I will be fine for the next 4 to 5 years regardless of the security update situation.

I will support phone manufacturers that have proper hardware, like a headphone jack and sd card slot over manufacturers that promise security updates every single time. I will continue to boycott phones that don't have a headphone jack. I will not make my current technology deprecated by design in order to have a supposedly flagship phone/device. We should support decent companies like Sony that don't remove useful features in order to create new revenue streams. I have really nice headphones, any phone manufacturer that removed the headphone jack is encouraging me to generate e-waste in order to use their product.

Right now is a terrible time to judge a phone company, the chip shortage hasn't gone anywhere, international markets are still heavily limited. Sony doesn't seem to be looking into becoming a replacement for LG, it seems to be happy existing in its current niche. The advances in camera technology engineered into Sony phones show it does not plan on going anywhere. I will be very disappointed if Sony leaves the phone business.

There are interesting phone manufacturers that I would like to buy a phone from, but they have essentially zero presence in the US.
If rich people were charged as much as poor people for drug charges, the war on drugs would be over tomorrow.

I know so many rich people who joke about doing cocaine and other illegal substances. Even the president's son has video of him repeatedly smoking crack cocaine and no charges are put against him (https://time.com/5952773/hunter-biden-memoir-beautiful-thing...). George W Bush allegedly did cocaine and no one cared: (https://abcnews.go.com/images/pdf/800a1BushCocaine.pdf)

There's not many other laws where rules are applied so unevenly as drug charges. It just becomes a freebie police can use to arrest someone they don't like.
The reality is the politicians always promise to do what people want but never quite actually do it, so that they can keep getting those people to vote for them.

Works painfully well all around.

It's fucked up though that merely possessing weed+firearm is makes you "prohibited possessor" with 10 years in jail when a NAND of the two is legal. Such a person may be considered a violator of weapons and drug laws, even though all they did was own a legal firearm and simple possession of weed.
This applies to somewhere in the neighborhood of 149 people[1].

Sarcasm is sometimes evident in written utterances. It's not clear whether the entire site is sarcasm or a different category of humor such as satire.
This isn't a "syndrome" it's normal adaptive behaviour. Like everything you encounter in the real world, 80% of everything you decide to start doesn't actually need to be finished. Sometimes you need to start something in order to learn you're not willing to pay the price to have it finished, or you don't really need it.
The basic problem for molten salt reactors is that the various reactor components are exposed to hot salts that are chemically corrosive, while being bombarded by radioactive particles. This is of course quite problematic when your goal is a machine that makes electricity consistently for decades. Equipment failures are an inevitability because we don't know of a material that has the properties needed to survive this kind of application. Curious how (or whether) the authors of this design approached this problem.
Absolutely. This product is particularly egregious. It's the most expensive boosters they've ever done by four times (and those were critized for being too expensive). They're not tournament legal, it's still randomized and filled with awful cards nobody cares about too. Sure, you could maybe get a Black Lotus or a Time Walk but you're much more likely to get something like a Animate Wall or Pirate Ship. And 3 of the cards in each pack are basic lands!

For comparisons sake the old collector's edition they did was $50 for 1 of every single card in Beta.
> I guess maybe the difference might have been that we (analysts) had degrees, and they didn't

AFAIK PICO-8 uses 32-bit fixed-point rational numbers under the hood. (And includes a whole range of math functions including trigonometry, square root, logarithms and exponentiation.)

Paris is fine for tourists. People just expect to be treated with politeness and decency which is not how Americans generally behave with staff.

Just say hi, please, thank you, ask people if they speak English or show a minimum of contrition when talking directly in English to show you realise it would be nicer to speak the language of the land, everything will be fine.

It’s puzzling to me why people expect things to go well visiting France without studying what’s considered polit and what’s not. It’s the capital of a country. It’s not Disneyland.

Missing my entire point: you can't cycle up renewables whenever you want, and that's the problem.
It's understandable that studying the constitution could be useful, but arguably so would studying the NEC.

In both cases it shouldn't be a requirement; we don't demand studying the NEC before using electricity.

And even those with a very good understanding of the constitution and civics probably don't have a very good handling on the actualities of how everything works, unless perhaps they're a criminal lawyer.
You are probably right. Thank you. Sorry there was what seems like an entrapment attempt coordinated between Fidelity and some other agency(ies), so that got me a little on edge.
What's the added complexity of STAR?

STAR is phase 1: sort(sum(candidates))[:2] (almost identical to score/approval/FPTP. We'd just take argmax instead of top two) and phase 2: eliminate other candidates, argmax(sum(candidates)) (identical to score/approval/FPTP).

On the other hand RCV is a multi-round system with a while loop. In practice it almost never has fewer than 2 rounds (requires overwhelming majority, which almost never happens with more than 3 candidates).

From an algorithms perspective RCV is more complex.
Are staff engineers needed? The role seems like a relatively new invention. Senior and midlevel IC engineers do the heavy lifting, principals set strategy and define architecture, EMs manage engineers, PMs manage product. I'm not clear on what the role of the staff engineer is and why it's needed.

I was curious how they achieve this. It looks like the underlying file format uses LZMA, or optionally Zstd, compression. Both achieve pretty high compression ratios against plain text and markup.

> If there is not enough of a flow of cooling water, the rods can overheat, and the entire facility is at risk for a nuclear meltdown.

This is not true. Water is the moderator in a light-water reactor. Without water the reaction will stop. Water is both the coolant and the moderator, unlike the Chernobyl reactors, which used graphite as the moderator.
The way I’m reading it, it also applies to people who are not incarcerated but still have felonies on their records.

If so, that’s a whole lot more than 149 people.
> No. No they don't if you're not being completely disingenuous. Jetpack AppCompat style libraries backport app functionality that older Apple devices will get via OS updates in a strictly saner way than having to rely on a backport of a TextView...

This is critically important, though. Look at Compose vs SwiftUI for example–Compose works really well, and even in beta was more stable than SwiftUI, which is nearly impossible to support on iOS 13 devices without massive kludges.

> OS-level functionality does not get backported and of course cannot come from library changes.

This is true, though not super relevant IMO. What OS functionality are folks missing on Android due to being behind? Security updates are the important bit, and most devices still get those for years.

> Gmail is not the Android built-in mail app, just like on iOS Gmail is an additional app that's shipped by Google.

The built-in app isn't updated because Google moved away from that model entirely. Why even bring it up? It's irrelevant.

> Headline features like Assistant changes, privacy and permissions, and system UI overhauls don't end up on your old device either.

Assistant receives updates via the Play Store: https://play.google.com/store/apps/details?id=com.google.and...

Good point regarding privacy & permissions, apps also need to use newer SDK versions to support those IIRC.

The UI overhaul is a weird thing to be concerned about on Android. If you care that much you will install your own launcher. And apps that care will ship the updated UI, one of the advantages of them just being libraries. I guess the notification pane won't update, but is that a huge deal? I'd guess for most folks the answer is no.

> Android's update strategy has resulted in a hellscape where Google is forced to recommend supporting a 6 year old version of their OS

It isn't perfect, but far better than supporting SwiftUI on iOS 13, for example

> What you're doing is like bragging that your neighbor's filet mignon is a little undercooked while you chow down on dog food.

Honestly this is just rude imo, no

To be clear, I think there are pros and cons to both approaches. I think somewhere in the middle would be better, but generally prefer the way Android approaches putting new APIs into older apps.
Those systems don't scale past single digit membership numbers. You could maybe keep in touch with everyone if you all had lots of sharded, overlapping groups, but what a pain that would be!
It’s amazing how underwhelming google’s product launch announcements are compared to apple’s. Not even trying to light up a platform holy war here, just saying that if you’re going through so much work as to create new generations of hardware, seems like something more than a press release is a good idea.
I don't know of a political system which doesn't work contrary to intention. You just hope they work and try to make them better. Cursing the times they do function seems weird.

Every U.S. president going back to Lincoln and before has triangulated their actions based upon the political circumstances of their moment. The Emancipation Proclamation itself was pocketed until it could be announced after a clear Union victory. I think the criticism is fine but it doesn't make Biden unique at all and keeping that context is important.
