It looks like the type of practice test matters a lot:

> a multiple-choice practice test increased intrusions of false alternatives on a final cued-recall test when no feedback was provided, whereas no such increase was observed when feedback was given

Sounds like practice tests are most useful when they are graded and the student gets that feedback. I suppose that makes sense. Flash cards and practice problems also fall under practice testing and it sounds like they were less effective.
California doesn't maintain order in schools or their major cities. If you want to live somewhere nice, that's liberal and has good schools move to Boston. If you want to live somewhere nice that's conservative and has good schools move anywhere in East Texas.
This is an underrated comment. I remember taking a Golden State Exam [1] in high school. It was for English and it required some essay writing. I didn't think I'd be in the top group so I wouldn't win any award, and I knew it wouldn't affect my letter grade. I spent the time writing random stuff that would fill the page instead of what I was supposed to write about.

It would be interesting to get data on how much students don't even try on exams that don't affect their letter grade.

> buy a Brother b/w laser printer

This.

People don't want crappy inkjet printers that are expensive to refill, the ink dries up, the machines break.

A medium-sized Brother laser printer is worth its own weight.

The only reason you may not want it is the space it takes.

Let's mostly have good printers and share them.

Are they extremely low?

I have kids in elementary school and so far, I would say "grade level" expectations are a bit higher than what mine were 35 years ago. But maybe things change as they get older.
Most doctors (in the US anyway) don't cover things until there is a problem. For example, someone can eat a diet that will lead to heart disease. But, doctors won't tell them to make changes until problems are already showing up.

This has to do with the way billing works for healthcare in the US. It's billed as sick care.

And, most doctors have almost no training on things like nutrition. So the impact of that isn't something they can help with.

If I were to suggest self study I would look at a couple things:

1. The Blue Zones. These are areas that researchers have identified where people live longer and thrive for longer. Something like 10x the number of people live past 100. Much lower rates of disease. Looking at how they live. There's a good book on it at https://www.amazon.com/Blue-Zones-Second-Lessons-Longest/dp/....

2. A good book by a dietitian. I like "The Proof Is In The Plants". Despite the author being vegan and the book talking about plants, the book covers meat and dairy along with amounts that are healthy. All of the recommendations include explainations of how this is known. https://www.amazon.com/Proof-Plants-science-plant-based-plan...
Despite how noble our stated goals are, the primary benefit to most families of public education is childcare. The state of things is more easily understood from that perspective.
> that only 50% of students are hitting that threshold is concerning to me.

Why?

I gave it a quick look so perhaps I missed some stuff, but the worst performance was Grade 11 math, where about 55% of students did not meet standards. But as someone who was great a math, and went to do it in Uni etc, I do not think its concerning that 60% of people do not know how to do matrices, calculus, or logic formalism or any of the other topics we touched in AP Math.

Valuing education is important, and I think we are behind the curve in how we teach our kids, tools like Google make tons of memorization so silly to prioritise. But kids not being up to speed with 17-18 year old metaphor understanding in English in a state with tons of immigrants, or kids not mastering calculus at 17 and not needing integrals later in life is part of specialisation, we cannot all do everything.
I have two printers (one at home and one at my office) and at least 3 family members who rely on my printers. In fact, they probably use my printers more than I do. I don't blame them, it's the same reason I don't own a boat.
Nth-ing the Brother laser printer recommendation. I bought one from Costco during the pandemic, hooked it, and everything just works - laptops, phones, etc. - and toner is dirt cheap and lasts for years. My wife is a teacher so she’s probably been responsible for 99% of the total page count and we’re still barely on our second toner cartridge 3 years later.
Math teachers speak English.

> it could be an indicator that people are less able to cope

That would mean life is worse. And we can measure how much worse in suicide rate deltas.
Printers are a pain. Full of stuff that dries up, in different ways. Rubber rollers become hard, print media dries up. And if that's not bad enough, predatory practices by the printer manufacturers with their "razors and blades" business models.

But +1 on Brother laser printers, at least older ones. I have two. Aftermarket consumables are cheap and good quality, and the printers, even at months between prints, just up and print, no fuss. The MFC7020 one can also scan and photocopy, and the other, the HDL2270DW, is more reliable than a lightweight plastic construction that can flip pages and print on both sides has any right to be.

I think it's proof enough that individuals are the wrong place to focus, that people from much-skinnier countries who visit the US often report gaining quite a bit of weight, even if they try to keep it under control. How are the natives supposed to do any better than foreigners who are starting fairly trim and bringing healthy habits with them from home? The problem is clearly environmental/cultural and must run damned deep if it's that hard to avoid it.

Which is terrible news because that's damn hard to fix without top-down initiatives, the likes of which the US has been allergic to since the '80s (though we didn't used to be).

I'm not making judgements, just stating the fact. You obviously seem to have it all figured out though.
I've never had any issues with my HP color laser printer. Bought it about 3 and a half years ago and have never had to change the toner. It just works whenever I need it and whether I need it to print, scan or copy.

I think you're probably fine with printers as long as you buy a laser printer. Ink printers are junk and unless you use it constantly the ink cartridge will die every single time you need it. HP's InkJunk printers are cheap because they know they'll recoup the price selling you ink cartridge after ink cartridge.

Years ago when Microsoft canceled its WinFS project, I began building the kind of file system that I wanted. Like other file systems, it had to be able to store hundreds of millions (or billions) of files and keep track of all their data streams even when they became highly fragmented.

After just a few months, I had a base system that seemed to work pretty well. Then I wanted to be able to define meta-data tags and attach values easily to each of the files, then find all the files that had certain tags attached very quickly. This part took more time, but I had that working within the first year.

Since then, I have worked years on adding new features to the project (https://didgets.com/) as each new idea comes to me. It now does database, logging, indexing, and other tasks well. For every task I pull off the 'TODO' pile and get it working, I seem to add two new items to the list.

I never thought it would be easy, but it has been even harder than I originally thought. But I love to program and enjoy getting an idea to work in code so I stick with it.

> Looking at the history this doesn’t seem abnormal, and it hovers around 49%.

Notice that the "historical data" goes all the way back to... 2014-2015. I'd put money on this percentage being significantly higher 20, 30+ years ago.

> This implies to me median is determined to be grade level (essentially) and it hasn’t moved materially beyond this point since the data was compiled and the entirely arbitrary definition of “grade level” was declared.

You may be both overthinking this and not understanding. The phrases "can read at grade level" or "can perform math at grade level" mean that a student can read/grasp mathematical concepts at the level expected of a normal person at the age equivalent to their grade (e.g., "can read at a 5th grade level" means "can read to the extent that is considered competent for a ten year old by educational standards"). The goal is for _100%_ of kids in a given grade level to be able to read/comprehend what is taught to them.

The Brother HL-L2370DW is in the same price class ($159) and is a solid monochrome laser printer. I'm about 1000 pages in and no issues. Maybe you don't like the dark color scheme, but I find it to be quiet when not in use, unobtrusive, about the same size as everything else, and no more or less ugly than other printers.
I agree, I'd rather have the cables NOT WORK AT ALL (or popup some horrible error message first) rather than charge at some abysmally slow rate.
"Blinken has long doubted that personnel are suffering from mass hysteria or some psychogenic event, officials have said. Previous investigations, notably by the FBI, had raised the possibility that the symptoms had a psychological origin, not a physical one, outraging many sufferers who felt their pain had been marginalized and their claims not taken seriously by medical personnel. Experts have emphasized that even if the illnesses were psychogenic, that doesn’t mean sufferers are imagining their symptoms."

I think therein lies part of the problem: it has to either be caused by secret weapons, or mass hysteria. The same kind of outdated thinking is what has caused the dualistic thinking that we see in ME/CFS and longcovid.

You'd think so, but I've taught ESL math. Good luck getting them to understand what's even going on without speaking their language. Especially if some, like my students, come in at high school having only really had five years of formal schooling.

You need the language to teach the math, basically. Also, not all of the kids I had were literate in their first language (A Mayan language, so most weren't) or even their second (often another Mayan language) or third (Spanish usually), so you can't just say 'Give them a workbook'

How to Start New Agile Software Projects: Building Healthy Teams
Watching Dr John Campbell in the UK receive repeated YouTube warnings for simply unpacking publicly available COVID research papers and public health statistics has been really depressing.
I wouldn't call codegen adversarial. The optimizer isn't out to get you. It emits the best code it can given a certain set of assumptions. It may just seem adversarial at times because the output can behave in unintuitive ways if you break those assumptions.

I don't believe PROT_NONE suffices. The address needs to be accessible, not merely mapped. If reading through a pointer, the address must be readable. If writing through a pointer, the address must be writeable. This is why writing to a string constant is undefined behavior, even though reading would be fine.

Another issue is alignment. If you read from a `*const i32` with unaligned pointer value 0x2, the optimizer is free to assume that code path is unreachable and, you guessed it, bulldoze your house. If you get a segfault from reading an `i32` from address 0x2, you've already hit UB and spun the roulette wheel.

In theory the emitted code could check pointers for alignment and validity (in whatever platform-specific way) before accessing them, and simulate a segfault if not. Such checks would serve as optimization barriers in LLVM, and prevent these instances of UB. Of course Zig's current ReleaseSafe doesn't do this, and I think it would be silly if it did. But that's the only way you could accurately call segfaults "well-defined".
> the idea that GitHub is hosting everything in a single datacenter is laughable on its face.

Personally I find the notion that GitHub is somehow magically superior to the rest of the entire internet a bit silly.

I’ve worked on distributed systems my entire career, I have yet to find a single one that is completely immune to a datacenter outage, there is always some single point of failure not considered- often it is even known, everyone has the “special” datacenter.

Its also true that “market forces” push for better cost optimisation, which can, in cases, lead to being not sufficiently sized to cope with an outage of a whole DC- made worse are people who think cloud will solve this; because every customer will be doing the same thing as you during a zonal outage.

Regardless of that; you are basically suggesting that github, as a centralised system, is better equipped to deal with the distribution of packages than a literal distribution of package repositories?

That’s odd to me, maybe not “laughable”, but certainly odd.
