> More on-topic, I wonder if the battery is fully functional with that 260% overcharge. Could be interesting if you can tell the battery (controller) “yes I accept the 1% point extra wear, please enable overcharge mode” for a really long trip that won’t have charging stations.

Overcharge doesn't mean that the battery can store additional capacity beyond its design limits. It just means that the battery won't be damaged or catch on fire if you continue to put electricity in it after it is already full.

So if an acre of rainforest were slated to be "developed" but burning, say, 1 55-gal drum of your favorite hydrocarbon would prevent it, and instead preserve that acre for 5 years, you would be against doing so, because it involves burning fossil fuels? If no, then your statement is untrue.

At the moment Chinese companies (well, WCH) dominate the stand-alone RISC-V microcontroller market, which has mindshare with engineers designing PCBs well out of proportion to the market size or profitability. Western companies dominate the market for RISC-V cores that are invisibly going into larger chips in huge markets such as mobile phone SoCs made by Apple, Qualcomm, and Samsung.

Chinese companies are also at the moment dominating the assembling of RISC-V cores into Linux-capable chips with the large collection of other IP needed for this, and putting those chips on to SBCs. But the CPU cores used are a mix of Chinese and Western ones, with for example SOPHGO's upcoming high performance 16 core SG2380 SoC using American SiFive P670 cores.

> It may save teacher time for teaching the middle group while also teaching the genius what it is to explain something so intuitive to someone who doesn't.

So, really no benefit for the genius and all the benefit for the weaker ones and the teacher who does not have to run their patience thin.

No, I think giving the genius a challenge that they came for is the best way to go about it. If you have none, that's fine, let the genius discover things on their own, they were almost certainly doing so anyways and its best to not get in their way.
> The point of elections are not to make dramatic changes, but to make tweaks.

The point of bureaucracy is to limit change, to not allow dramatic change.

The point of democracy is to make decisions. And the larger the groups of people and the less frequently voting happens, the larger the granularity of those decisions.

Decisions should be able to change bureaucracy, add to it or subtract or realign or whatever.

When bureaucracy is used to gate-keep decisions that can be made in a democracy, it's not really democracy any more. And I think a lot of people, regardless of their political beliefs, believe that has happened: nominal democracy where votes don't really matter because they can't affect the bureaucracy.
Honestly, the bigger issue here is that good math teachers in the US are just in short supply. Sometimes I wonder if the way we teach algebra here is flawed, like something pedagogically or conceptually, and good teachers break through that to give students what they need to prepare their students.

I think it was Mark Johnson of the linux matters podcast that was talking about how he's experimenting with integrating his blog with the fedi-verse using aws lambda for the dynamic parts https://linuxmatters.sh/16/

I also read another blog about it a while back, but essentially you have the same issue as comment systems where it can't be static, there needs to be some server component handling the back and forth.
Are you sure? TETRA uses frequency-hopping spread spectrum, which requires a much wider contiguous bandwidth allocation for this modulation and use. That allocation doesn't exist in the US.

The lack of any large allocation for this kind of radio is a big part of why US first responders are stuck with P.25, which is narrowband FM. If there were a wide-enough band in which it could be used, a lot of first responders would have bought TETRA radios a long time ago. P.25 is easy to jam by brute-force power output, and trivial if you directly attack the error correction bits. TETRA and FHSS have a much much larger ratio of attacker transmit power to victim transmit power.

(FWIW, P.25 is an even worse dumpster-fire than TETRA...)
This is why.. shudder.. Microsoft appears to be the leader in AV (EPP). I also don't want an extra party involved, so ideally, the OS provider should also provide the EPP.

"Crazy on-call expectations that require you to be available and potentially working at any hour of the day and night" is something very different than the topic under discussion, and I didn't interpret sublinear's comment at all to be endorsing that viewpoint.
Even in the STEM world I don't think statistics is taught all that well.

I studied Engineering a STEM subject, this was sometime ago (2000's) and at that time we were required to take a "statistics for engineers" course in the second year of the degree. The subject was mostly useless (it pretty much boiled down to "plug this data into Excel and this is how you interpret the ANOVA output").

What I really wish they focused on was regression analysis and especially non-linear regression, logistic regression etc. I had to learn all about it in the workplace after graduation.

Even the statistics knowledge we were taught was incomplete - for example I did not learn about Cross-validation at university.

talking to more recent graduates I don't think the situation has improved all that much in the intervening years.

Many schools do teach this. It’s not required but some schools do offer it as an elective. However, as practical as it may be, many teenagers just aren’t interested in learning about personal finance.

At a more philosophical level, should schools even teach personal finance? The math itself is very simple and many adults can learn it on their own, without guidance from any instructor. All they need is a couple of good blogs and YouTube videos.

The classes schools teach and the curriculums they offer are limited. There’s only so much time in the day to teach a wide variety of topics.

So, should educators spend time teaching subjects students could otherwise learn themselves? Without an instructor, assignment feedback, etc, would people still pick up something like physics or calculus on their own?

My personal opinion is that K-12 and college should focus on complex topics like algebra, chemistry, and physics, while simpler courses like personal finance could be taught by parents or by a students self. Happy to hear the debate around this though, it’s always fairly interesting.
Doom helped me out of a crippling fear of hell/damnation that was beat into me by a religious upbringing and I will forever be grateful.
All jobs done on a computer are information processing. AI is approaching human level information processing in every benchmark we can throw at it. By the time it eclipses all trained humans, using an AI to do a human job will be a no-brainer, as AI's:

1. Don't require health insurance/mental health leave/PTO

2. Can work 24/7

3. Are infinitely replicatable

4. More interpretable/modifiable than human intelligence

2 years ago the best AI art models were worse than 99% of human artists, now they're better than 99% of them. The same thing will happen to every skill that isn't based on motor/sensory abilities.
I also built something along these lines about three years ago and use it every year. I started off with a stainless steel hall effect float switch and it's lasted so far, on its fourth year. I don't have a pump for my water, I use my RO system as a source and a solenoid as a valve. I do use a peristaltic pump to meter out Christmas tree preservative according to the readings from a flow meter on the water side though. It's worked wonderfully, even when changing tree stands.
Some detailed (or even interactive) examples would be great, otherwise I won't be interested enough to dig in further or schedule a demo :)

16-year-old Looking For Guidance
Hello, I'm a 16-year-old seeking guidance for the next steps in my software journey. I've completed 100 days of coding on Replit and have undertaken several HTML, CSS, PY and JS courses and tutorials. My goal is to enhance my programming skills and eventually secure an internship. While I still am not sure, I am interested in ML or AI engineering but am aware that is hard and might be too hard for my skill level. Currently, I'm exploring ways to further improve, such as engaging in projects or any other suggestions you may have. If you have any project ideas, it would be helpful. Any other advice would be much appreciated.
People who have some understanding of study design and data collection would be in a much better spot to understand and interpret day-to-day news / “information flood” than those who have done a lot of calculus-based probability. You can go all the way through rigorous measure-theoretical probability and come away with almost nothing useful for interpreting a study.

Most problems I see with moderns statistics aren’t of the form “ohhh, they fooled you by using a subtly wrong statistical metric to ascribe significance” but “the way the data was gathered/interpreted is fundamentally wrong and made to mislead”

Don't speak English at home. You should not and the kids should not either. It's very easy for kids to forget the second language once they start school. They will want to speak English only and forget everything they ever learned of the second language even if they were at one time fluent in it. If you can get them to read in both languages that will be a great way to expand their abilities in the second language. Bilingualism is a lifelong process. It is a case of, if you don't use it you lose it.

We can already induce various feelings and qualia through the use of chemicals (drugs) and EM fields (tDCS). There's no evidence or proof that these physical domains are insufficient to explain qualia. Likewise, demonstrating that feelings and qualia can be induced via quantum interactions doesn't reveal anything deeper about their nature than does the fact that we can induce happiness or hallucinations with drugs.
Man, I'd forgotten about WriteNow. It was my favorite word processor on the Mac for years. (I'm pretty sure at one point -- long after it was defunct -- I acquired a copy of the very last released version, which crazily enough was published by WordStar.)
While I appreciate the analogy, it's important to note that registers are a fairly advanced feature, not quite as ubiquitous as Ctrl-C. Standard Emacs copy-paste remains unchanged and functions just as expected.

O'Rourke, "Computational Geometry in C 2e". Deals with the basics in a principled way. Start here for fundamentals like a good algorithm for intersection of two lines, or inside/outside polygon tests (don't depend on garbage blog posts for well studied fundamentals like this).

I am now hired by a big company. As far as I understand, it is to become a “manager” (==a politician). So now I spend my days having pointless meetings with bozos.

Because of the poor management, we have had reorganizations and budget cuts all along the year. Making proper work impossible.

So now, I simply code what we need, after hours. This is exhausting, as it is double days. But extremely valuable in the end.
> calculus vs. statistics debate

this is no longer the debate. the debate is whether kids should have to take math classes at all in order to graduate. And based on what i'm seeing, the answer the schools came up with is - No.

Similar story here. What I learned in math in high school was an absolute joke. It in no way prepared me for physics and math in college. In addition, most college majors do not need it, they need an understanding of statistics, and a much better understanding of 'business math' and algebra. I think dividing kids into two or more tracks does not hurt them, because they can always take extra course work in college if they ultimately decide they want to pursue STEM. Where it hurts them are the standardized tests, this seems to be the issue.
The "STEM World" is a large one and "XXX for Engineers" courses in undergraduate university are long on material to rote memorise and short on depth required to understand and expand.

I took engineering myself, the Physics, Maths, Chemistry 110 "for Engineers" variations were shallow compared to the Math 100 etc core courses for those who wanted to study Physics, Mathematics, specialise in Chemistry, etc.

Mathematics, medical, and biology students who take statistics for epidemiology and other sensitive applications get a much better grounding in the pitfalls and meaningful operations of low dimensional summaries of high dimensional data.

Analysing data is similar. I'm all for it, it's clearly useful on the days when my main working tools are slack and powerpoint, but it's not clear to me how teach that without math. One of my math textbooks even had the word "analysis" in its title. ("Calculus and analytic geometry" perhaps?)

I'm always going to code with a connection to the internet. I shouldn't need to mentally keep track of local vs remote because that distinction simply shouldn't exist.
To be honest, I'm not that concerned with high schoolers needing "a rigorous and thorough statistical education."

I'm more concerned with the populace at-large being able to understand and apply fundamental statistical concepts. For example, another commenter mentioned Bayes Theorem, and how it's a very powerful idea and not that difficult to grok. Related, predictive value positive and negative, and how they are calculated from (but also very different from) sensitivity and specificity, are extremely valuable concepts to understand.

To what you point out, I think the concept of "p-hacking" is super important to understand, but I'd be less concerned about a student needing to hand-calculate the steps to run a t-test (that's what a college-level class is for). That said, I decided to look up T-test on Wikipedia while writing this comment, and I found this interesting tidbit. Great example of the applicability of statistics, and something that I think would peak the interest of many high-schoolers:

> Gosset had been hired owing to Claude Guinness's policy of recruiting the best graduates from Oxford and Cambridge to apply biochemistry and statistics to Guinness's industrial processes.[13] Gosset devised the t-test as an economical way to monitor the quality of stout.
Honestly none of them are particularly incredible compared to neither. At this point everything is a prototype, there’s no sense in building knowledge specific to them unless you’re also building LLM products.

It’s just distributed ADHD at this point. LLMs are new and cool and each new release will be significantly better than the last, but as with any emerging tech, we’re on an exponential curve so there’s no sense in falling in love with specifics or products until things stabilize.
