> Just because you played Quake doesn't mean the web is good for "vast majority of apps"

It means that at least 15 years ago it was more than powerful enough for all of the 2D Candy Crush style games which make up the overwhelming majority of mobile gaming apps.

> The web can barely display simple text and images without jank because that is inherent limitation of the DOM that you cannot escape

I've seen you repeat this phrase over and over again like a mantra on HN, but without examples I can't really gauge the performance problems you've run in to. The overwhelming majority of jank on the web that I've experienced is due to advertising bloatware (an adblocker is indispensable), and occasionally bad engineering (e.g. someone forgot to make an event listener passive, or isn't debouncing an event) not some inherent limitation of the platform. What are some examples of popular apps that you think require the full brunt of a modern chip? Every M3 iPad review I've watched ends up saying essentially the same thing: "this chip is powerful, but besides Geekbench benchmarks we have nothing to use it for".
10,000 hours also isn't that long in the grand scheme of things. I remember when I broke 10,000 in the arts, then 10,000 writing code, and so on, I dont even keep track now.
The "worked example effect" they talk about it interesting. The idea that you learn best from worked examples lines up with my experience. However, it seems like higher math abandons this completely. So many math textbooks are just in "theorem, proof" form, with almost no examples or even motivation.
There are things you can do with yourself that you’re not OK with strangers doing them for you.

That’s pretty much the issue with privacy. A lot of feature feels invasive because the company don’t want to remove themselves from the operations. People don’t usually care because they either don’t understand the impact or they trust the government and the laws to reign in malpractice.

This is a great library, but as far as I understand it is rather for bare-metal or low-resource embedded operating systems, not for Linux. The OP apparently runs Linux. Could he also use LVGL on Linux and write to the FB device?
In my experience, tech debt often requires too great an investment to fix so the team just ends up bikeshedding to show progress but without real benefits.

Look at C. Each revision has added a bunch of minor fixes but has never addressed the core issues of the language that realistically require a rewrite (function pointer syntax, undefined behavior, null safety).

And there’s the fact that features bring in money and tech debt simply doesn’t. It’s still a business at the end of the day.
i became aware of this recently and your comment reminded me to listen. this is great! thanks!
I feel this article's argument is weak, largely for one key reason: They don't clearly define anything. Their references might clarify some things, but not all. They argue against "general problem-solving strategies" with a reference to Polya, but they don't provide a clear definition of what these strategies entail. How broad is the set of strategies they're arguing against? What are some examples of such strategies? I'd like something beyond two sentences on Polya.

Furthermore, what audience and level of mathematics education are we discussing? The goals (and hence appropriate metrics of success) are certainly different for high schoolers targeting non-STEM careers vs. engineering undergrads vs. math grad students. The authors reference "aspiring mathematicians" and "domain specific mathematical problem-solving skills", indicating they're arguing about education for math majors, or at least students in STEM fields. In that case, the argument is somewhat meaningless - who's arguing math majors shouldn't learn math-specific skills? But, as I understand it, the argument for general problem-solving skills is that students outside of math don't actually need many specific math skills. Instead, math is a vessel for teaching logic, reasoning, and problem-solving skills. Then again, this might not be the type of problem-solving the authors are referencing - as I said above, it's not very clear.

On a similar note, they cite evidence that studying worked examples is more effective than "general problem-solving strategies", citing an "improvement in subsequent problem-solving performance" without explaining how this performance is measured. If students are tested on specific problem types, of course they'll perform better when taught strategies for those specific problem types. But it's not clear that this is meaningful. For STEM majors, sure, solving specific problems is a skill worth cultivating. But for most students, solving specific problems isn't as important as learning logic, reasoning, and general problem-solving skills. In my anecdotal experience tutoring math, students tend to just memorize strategies for specific problem types instead of learning transferable logic and reasoning skills because that's what's tested. I'd be curious to see which method of learning facilitates better performance on a more general problem-solving test of some sort.

Now, I'm not an education researcher or an educator of any sort. But I am passionate about good STEM education, especially in math. I genuinely feel that math education fails most students, at least here in America. If I'm being generous, this article is a well-intentioned but poorly-executed argument for effective math education strategies. If I'm not being so generous, this article advocates for the status quo in math education that forces students to slog through years of math classes for little discernible benefit. Either way, it's a disappointing article with a poorly-explained thesis.
I live in an area where the prevailing accent is a flat US midwestern one, and watching Bluey has led my toddler to derhoticize her R's some of the time. (The sound ends up like a muddled Australian-Boston mix.) I assume the reverse happens all the time with kids from other countries who see American TV, but it's something amusing that I didn't expect. Her mom and I are both unable to roll R's, so I wonder if playing a lot of Spanish audio will help her be able to do so.

>beyond addictive

No, it's not addictive. That word has a meaning and it does not apply to this context. The DSM V has addressed the "social media" and "video game" concepts re: addiction with committees multiple times and every time it's very clear from the science: there is no addiction. And no, personal anecdotes do not overturn this. You might use the word "disorder" like the DSM V's grandfathered in "gambling disorder". But it is not an addiction.

The idea of "addiction" in the context of stimuli from screens and speakers is a meme with no more basis than slenderman. Huge popular awareness but completely made up.

Nice to see a response from you!

I have read the rest of the argument. However, my take upon reading it is that this is just one more contribution in a back-and-forth argument about every aspect that has been studied in math education. Despite the fact that this was published in 2010, the landscape in 2024 very much points to "it's unclear" as the answer to "is [anything] effective?", at least for me, unfortunately.

You'll want winter tires on well before the air temperature hits freezing for water. Forecasts aren't that predictable, and bridges (no earth heat sink underneath) will ice over before roads do.

40 F is a good time for getting winter tires on.

As someone who lives in a humid, wet area that goes from -40 at night in winter to 100+ F in summer, I also vastly prefer Fahrenheit.

The difference between 60, 70, 80 and 90 is pretty profound with humidity, and the same is true in winter. I don't think I've ever set a thermometer to freezing or boiling, ever. All of my kitchen appliances have numbers representing their power draw.

I'm referring to how first-past-the-post creates great distortions in how it allocates seats relative to how people voted (i.e. the popular vote).

For example, the Bloc Quebecois and NDP won 32 and 25 seats, respectively in the last election but won 7.63% and 15.98% of the popular vote, respectively.

That means even though more than twice as many Canadians voted NDP than BQ, the NDP won fewer seats.

There are plenty of these examples through the years where all major parties (and the people who voted for them) got short-changed at some point.

> And yet, somehow, there are still no amazing PWAs

There are plenty of great PWAs. People bring them up on a regular basis and you piss and moan when we say Facebook, YouTube, Twitter, Mastodon, Pinterest, Uber, Trivago, Starbucks, Dominos, Stitchfix, Adam & Eve or Hotels.com are usable online. You specifically complain because none of these apps are killer features to you. I don't know what to say; clearly they exist and you're trying to minimize the number of apps that technically qualify.

People refuse to take you seriously when you repeat this same tautology. Of course PWAs aren't popular on platforms that deliberately go out of their way to make them infeasible alternatives to a first-party service. It's not my fault that your purview of the technology is arbitrarily limited.
They were garbage in hindsight. Being "blinded by the hype" is what drives people to try new things and fail. And that's okay! It's okay that we ended up with a handful of viable companies. Those viable companies emerged because people tried new things, and failed. Investors lost money because investment has the risk of loss.
> Maybe you haven’t had reasons to come across such research before

No op, but I’ve “come across” a lot of education research. By “come across”, I mean I’ve read so much that it makes my eyes bleed.

There is some good research that yields interesting and compelling results. Rare, but out there. Usually by an individual researcher and maybe with a team. Almost never by a school of education of significant size or by (almost?) any specific field in education.

Results in education are challenging to replicate by a different researcher in a slightly different context, and studies are often trivially easy to replicate and come out with a competing/contrary conclusion by controlling a variable that the original researcher mentioned but did not control for (e.g., motivated subjects versus unmotivated subjects).

Additionally, much research in education is not well-designed, or is well-designed but on a relatively meaningless topic. There is a lot of touchy-feely research out there (like the idea that folks can learn math with just problem solving skills), and folks p-hack the hell out of data to support their a priori conclusions. It’s a smart thing to do to maximize funding and/or visibility in academic journals, but it is absolutely irresponsible in the quest for “truth” and knowledge, which one would hope our education researchers would want (n.b.,they largely don’t).

Thanks, went through this also before launch, after implementation I was browsing stations and one started playing video :) Thats when I put HLS aside and will explore more once I can have certainty that video streams will not be part of it.

I don't get it either. If UUIDv7 lacks security due to its revelation of a timestamp, why don't bigserials also lack security? After all, given a bigserial ID, you can tell whether it was generated before or after some other bigserial ID and thereby infer something about the time it was generated.

Correction: with the tool you created and are not-so-subtly trying to market right now. Complete with an $18/mo subscription fee, no users and (of course) a cryptocurrency that's fueled by promises and hype.

No, despite the conspiratorial twist, modern tooling is more flexible and easier to use than ever before. It has flaws, but those flaws are nothing compared to what developers had to go through a couple of decades ago. There's no big collusion to cover up your tool.

“Send it somewhere else” being the important part.

The interface Chrome went with was a declarative list of filters that Chrome will use to perform the actual filtering, but the declarative interface isn’t great and wasn’t well received.

My point is: there is an interface that is non-declarative and sandboxed, whilst allowing Chrome to perform the actual filtering.

> And perhaps at the very top of this hierarchy is memorizing just generic problem solving strategies/learning strategies.

I'm not sure this counts as memorization. I don't even think you can really "memorize" high level learning and problem solving strategies, even when explained by an expert. You kind of have to re-discover them internally. And then, there are people who "memorized" the explanation and are completely unable to put it into practice because to them it's just a word sequence, instead of an internalized change to the way you perceive and work with problems.
Or people with a reasonable CNC machine (even prosumer grade), that takes the time to make some setup templates.
I think this goes too far, but I do think math is… overrated? Kinda? Overrated isn’t exactly the word I want, but there’s definitely something weird going on.

98% (I’m being generous) of people can no longer work almost math past early algebra and maybe a handful of finance-related plug-in-the-numbers formulas by age 35 because, assuming they ever learned any, they have never used it, so it’s gone by then. And that state of things seems to be entirely Ok. Like, if they needed it, they’d have used it and the many of them who could once at least kinda work with calculus, or what have you, wouldn’t have lost that skill.

Meanwhile, I’ve not found the “it teaches problem solving skills, that’s why it’s important even if you never use 80% of it outside of school” thing to really hold. Maybe for the kinds of courses math majors take in college, I dunno, but not for the rest. If it does teach any, they don’t seem to generalize well for almost all people who learn them, and the rest, I think that’s more about who they are than that they took some math courses.

Ultimately, it’s not clear to me that if we taught quite a bit less math to most kids and even college students, anything bad would happen.

I think there are probably ways to approach math in primary and secondary school, and maybe also math courses for undergrads who have a small load of math courses anyway, that would temper its evident uselessness quite a bit—namely, a laser-focus on applications past the very earliest grades—but most math majors seem to want math education to go exactly the opposite way. Maybe they’re right and I’m wrong, I dunno.
