Schools are set up for the convenience of the people who work there. Mastery learning is a nightmare. Differentiated learning is really hard because you have to teach what amount to three classes at the same time. Mastery learning is worse because you have to try and teach as many classes as there are students. I exaggerate but you get the point. I know of absolutely no examples of schools using mastery learning. The school I'm in moved to streaming English classes by ability for grades 6,7,8 (Foundation) into A,B,C,D and 9 into A,B,C. Teaching the Foundation classes works ok but I can see why so many teachers hate streaming. Teaching lots of low ability/motivation students is unbelievably dispiriting. Low ability students you can at least help but if you're teaching them something they don't care about, like most teachers do for most of every class then low motivation students are hell to teach.

Schools are mostly child care and ranking by academic ability. Education is secomdary. Mastery learning is really hard and would reqire a wholesale reorganisation of schools. That's a large part of why it isn't done.

Not just mammals, either! Wasps aren't averse to getting lit up when it's late enough in the season for fruit to have fermented. Sometimes they get too wasted to fly home, like the bald-faced yellowjacket I found sleeping it off on one of my porch windows a few months back - there's a fig tree in my side yard with some branches too high to reach, and it was very popular with her and her sisters for a while this year.

> "high culture", the stuff that is somehow supposed to reflect on human condition.

"High culture" is first and foremost about marketing. Many people care more about things that are marketed as too good for the average man, and products marketed for that group is called "high culture", the name is a part of the marketing.

It is similar to the difference between cheap wine and fine wine, people don't notice a difference until you tell them one is more expensive than the other and then suddenly people start noticing a huge difference.

Italian competition watchdog fines Apple, Amazon $225M
I think there's a difference between where companies are listed/head-quartered and where the work is done (e.g. Google seems to have 4 separate offices, just in London).

Or consider India, where huge amounts of dev work is done - but nobody can name an "Indian web brand" (internationally).

Only actual European brand I can think of that's made global impact is Spotify.

Europe seems to do better on the less fancy consumer facing side of IT - reasearch and 'hard' companies like ARM.

The US wants to sell its liquid gas. While I would prefer the US as a partner compared to Russia, this is just stupid banter and I think fracking should be minimized as a method for gas extraction (Russia and Germany do the same, although in a smaller dimension).
> Really? How many of the 70 billion land animals per year slaughtered for food
were rescued from the wilderness, as opposed to bred in captivity?

How should I know? There's no statistics about that kind of thing. And yet it
happens all the time: that's why farm animals have bells around the neck so
that when they wander off and fall into a ravine or get stuck on a tree (goats,
for you) the farmer can find them.

But aren't you moving the goalposts? First you said "farmers aren't going out
and rescuing cows from the wildernes". Now you're asking how many do.

I have to ask, other than the horror youtube videos of vegan propaganda, is
there anything else you know about farming?

> Btw I hear this argument all the time and it's really silly if you think about
it honestly.

So you mean to say I'm either silly, or dishonest? And that's not meant to shut
me up and end conversation with a "win"?

Well I won't beat about the bush as you do. I think what you propose is
demented. You're suggesting that, to avoid killing animals we should genocide
them instead. As if extinction is a better option than living a healthy and
happy life and dying at the end and in a better way than the animal would die
anyway, except it's now humans killing the animal, which seems to be the only
problem with the current status quo.

Hey, I know. Maybe we should genocide all the wild animals also, so that they
stop killing each other in horrible ways and dying half-eaten by something.

Oh, wait, that's actually a thing:

Fine, but my point is there is no reason for Brexit to be a net negative when it comes to the funding of PhDs - if anything, it offers an opportunity to be more effective at funding.

I have lost count of the studies that can't tell the difference between a Fine wine, vs 2 buck chuck.

(To the alcoholics out there, whom have tried all the programs, etc., to no avail, but want to cut back.

There's a box white wine in most large grocery stores that has 9% alcohol. Most wine is 12% up to 17% I believe.

It doesn't taste great, but that's a good thing, and it's pretty hard to develop a problem with it.)
> Not everyone will use a token or remember it. If even 50% of voters do this 100% accurately, it still isn't statistically helpful.

I think this is its main weakness. Those who don't care enough to use a token would leave the token of zero effort (nothing)
open for manipulations. Unless those are few, this system won't make the election more secure.
It would however give those who care a way to ensure that their vote was counted, increasing public confidence in the results.
For I assume that those who care enough to question the results also care enough to use a token and check it.

> It's also worth saying that if there's any problem with this system, it calls the entire election into question, even if the election itself was fine or statistically far from error.

> You might look up your vote and think "shenanigans!", and there won't be any way of looking at your original ballot to find out what happened.

The token is only needed to identify a vote, so it could be dead simple,
like a bitmap that could be a grid to be painted on paper ballot. It can be just added to existing systems.

> And even if there were, you still wouldn't have any way of verifying that your vote was included in the count.

How is querying the tokens used to vote what you voted, seeing your token in the list,
and checking that the tokens make up the reported total not verifying it?

> We (especially in tech) focus myopically on election fraud in the US, as though that's the thing that would undermine the legitimacy of an election.

I think it's just because it seems like something that could be solved.

> I am 100% sure that even if we implemented this system, they would still work just as hard to undermine election legitimacy.

It would be a little harder when those who care can just check that their vote was counted.

> I think we'd both like to increase the legitimacy of elections --

It seems to me that we have somewhat different aims.
You have zeal for democracy and are willing to compromise ballot secrecy to verify the election result.
I accept that verifying it is impossible while maintaing the secrecy, unless everyone is willing to check that his vote was counted.
In practice I would be content if everyone just had that possibility, as I don't have unrealistic expectations of its popularity.
Blockchain Gaming and NFT report 2021/10 [pdf]
I live in Japan and some of this is a bit wrong.

1. All Tuna is frozen immediately after being caught on the boat - go to tsukiji (well now toyosu) at the tuna market. They are frozen and they taste better because of it.

2. There is no sushi / sashimi grade in Japan. High quality fish that you can eat safely is just the default

3. It's true that traditional sushi did not include salmon because of the parasites. If you go to a traditional sushi restaurant (3 star Michelin etc) you won't find salmon nigiri. Other than that salmon sushi is everywhere at sushi restaurants in Japan and tons of Japanese eat salmon nigiri and sushi.

Europe is a non-issue for hosting because it's where I live and services are plentiful.

I'm going to pay for a fixed IP on the fiber I can get that on and host the first DNS on my own hardware with lead-acid backup.

> How much progress could we make if Steam deprecated their runtimes, abandoned containerization for new games, and let all new games just use the native system libraries? How loudly do you think gamers would complain if a distribution upgrade broke their favourite game?

If the steam runtime didn't exist, most gamedevs would only target the most popular distro - probably the current Ubuntu LTS, and you would have to recreate the runtime on your distro of choice.

And once there's a new Ubuntu release you would also have to recreate it there (or the game updates and now you'll have to recreate it on the now-old version).

The choice isn't between steam runtime and a utopia, the choice is between the steam runtime and something much worse. Linux libraries simply aren't stable enough in API and ABI.
Diesel is the leading ORM for Rust and they allow you to build SQL queries in a type safe way, as well as, making sure the struct you deserialize to matches the output of the query (ie, type safe deserialization).

I've used ActiveRecord and Django's ORM, and neither provide anything like this.

The closest I've seen is SQLModel, a library on top of SQLAlchemy built by the author of FastAPI.

However, last I checked, the kinds of queries that Diesel allows are more restricted than that of Django or ActiveRecord. Of course , you can always write custom SQL for things like that when using Diesel.

I believe also that Diesel is either maintained by or was created by the same peeps behind ActiveRecord. I also read somewhere that a running joke among them is that they learnt what not to do in writing an ORM through ActiveRecord.

A question I have for y'all is: can anyone make a comparison between Diesel and TypeORM?
> The high heritability of educational achievement reflects many genetically influenced traits, not just intelligence

> Because educational achievement at the end of compulsory schooling represents a major tipping point in life, understanding its causes and correlates is important for individual children, their families, and society. Here we identify the general ingredients of educational achievement using a multivariate design that goes beyond intelligence to consider a wide range of predictors, such as self-efficacy, personality, and behavior problems, to assess their independent and joint contributions to educational achievement. We use a genetically sensitive design to address the question of why educational achievement is so highly heritable. We focus on the results of a United Kingdom-wide examination, the General Certificate of Secondary Education (GCSE), which is administered at the end of compulsory education at age 16. GCSE scores were obtained for 13,306 twins at age 16, whom we also assessed contemporaneously on 83 scales that were condensed to nine broad psychological domains, including intelligence, self-efficacy, personality, well-being, and behavior problems. The mean of GCSE core subjects (English, mathematics, science) is more heritable (62%) than the nine predictor domains (35–58%). Each of the domains correlates significantly with GCSE results, and these correlations are largely mediated genetically. The main finding is that, although intelligence accounts for more of the heritability of GCSE than any other single domain, the other domains collectively account for about as much GCSE heritability as intelligence. Together with intelligence, these domains account for 75% of the heritability of GCSE. We conclude that the high heritability of educational achievement reflects many genetically influenced traits, not just intelligence.

Has anyone heard from the President a message to reduce consumption in the U.S.? We waste so much, there need be no hint of tightening belts or doing without things we like. Most Americans could drop our emissions and waste 50 percent just improving our lives. We live this huge lie that consumption correlates with quality of life, health, or happiness for most of us.

We could improve our lives by cutting out most of the useless, pointless junk instead of solving every problem by burning more fossil fuels.

Yeah, really. OSX DMG's contain AppBundles, a concept OSX inherited from NeXT. NeXT wasn't the first implementation of the idea either, in fact pretty much every non-unix desktop OS ever released used some variation of the concept including DOS and the original Mac.

Sadly, it seems the Linux world just can't wrap its head around the idea of managing applications with the same simple mechanisms we use to manage regular every day files. It would seem that Linux Desktop users just love having inflexible management tools do it instead. Well, there is AppImage, but unfortunately its use is not wide spread.
Educational Podcasts Can Impact Learning
I like winamp, and continue to like it, because it gets out of my way. All the essential controls were readily accessible, including an EQ which almost all players lack today. The generative, music responsive displays were whimsically cool too. And it didn't constantly bug me to set up a play list for everything.

What does Spotify have? Half the time I can't even find the repeat button, or somehow it decides it should shuffle. And don't get me started on that mess called iTunes, and VLC crashes constantly and has lots of irritating quirks.

Re security: This is probably best fixed by packaging apps with SELinux rules, which are enforced and cannot be disabled, plus responsive maintainers. There could be more than one app version to allow different SELinux rule strengths, per-app.

Re disk space: no mention of Nix? That also solves updateability for security issues.
Another solution is Gentoo's -- deliver the sources and recipes, (re)build as needed. That could also work in userspace.

It would be nice to be able to 1) distribute Linux GUIs 2) let friends install them easily 3) have the friend edit the GUI app logic and run the modified version. AFAIK, this is currently only possible with apps based on interpreted languages (e.g., Python+GTK), but even there you'd need to guide your friend to install the required packages.

Re "the state of software complexity in 2021": Ignore complex software, and just don't include it on your system. Start with a subset, and add only what you need. That's how OpenBSD remains manageable. If people want to extend, they can go ahead. But you don't have to fix the world.

That is a good point. It is a good observation that just binary encoding numbers does not mean you have an efficient serialized representation. And, that sometimes that can be so bad that even encoding numbers as serialized text beats it out.

I think what threw me off was the context of this discussion, which was 3MF file format. For such cases, the usefulness of humans opening up the data in text editors is somewhat contrived. I believe that tradeoff for the 3MF format was a mistake, and will likely hinder broad adoption. I'm however mostly concerned with the extra processing required in order to decode the human readable files. We're talking a likely speedup of a factor of 50-100. For models that push this limit, imagine a file that takes 60 seconds to process. This isn't entirely unreasonable for a model with insane level of details. If they instead had gone for a binary file representation, the load time would likely be less than a second. Failing to recognize this tradeoff for human readable text... is unfortunate.

Did people really explain things to you at university? Where I went you were expected to read a lot on your own, and then you had a few hours of tutorials where you could ask some questions.

For high school, you're basically right, there isn't that much content. But it's not like you're in a math class particularly long either. Few hours a week for a few dozen weeks a year, for a few years, and a fair bit of each class is getting everyone seated, telling people the homework, and reviewing the previous lesson. If you look at a math/science high school curriculum, you tend to just follow some book that's a few hundred pages, and it takes the whole year to do it. An engaged kid could read it all over a few evenings, per class.

> It is really irritating to me how so many people thinks it is impossible to grasp math by just sitting there

It's very easy to think you really understand something when someone's explaining it to you. Kinda like watching a show on Discovery. Then when it comes to solving problems, there's a fair chance that you're exposed. I found this a lot at university, there'd only be 10 questions but they were good ones that necessitated looking at a variety of sources and getting a real understanding. Often nobody I knew would be confident on all the answers, and this is kids that got into a world famous university.
