I’m all for exploring new ways to educate kids but does anyone else think it’s kind of weird these experiments are happening in public schools?

Why not set up low-cost private opt-in “Lab schools” instead? That way, if the experimental program isn’t working for a student they can transfer back to regular school.

My ongoing experience is that this question is never asked in good faith so please don't misunderstand me.

What I am saying is: I think you know and you have an agenda.

If you truly don't know then this is really something you should know if you are doing the job you are saying you are doing.

To use an analogy: I would not waste my time explaining how type systems work to someone who is arguing rabidly against them in an online forum.

If they care then it's something that is so important they should actually go out and educate themselves before getting into conversations about it.
Cobalt is not a critical metal for all lithium-ion cells, only for maximum energy density lithium-ion cells. If you're willing to sacrifice energy density you can use lithium iron phosphate instead, which is also safer and more durable. BYD Auto, the Chinese company behind the great success of electric buses in China (preventing more CO2 emissions than electric cars) uses lithium iron phosphate.
No. China does not even see the US's world wide system of military bases as something worthy to be mimicked.

I think you're right, just did some careful testing and it looks like the 'probability cone' (basically, the shape you see if you only look at the shape drawn out by the 1 std dev / 2 std dev lines) does have the right shape. My apologies for jumping to conclusions there :)

However, I can't replicate the numbers that you create for a simple test case:

https://imgur.com/a/ogP1ucY
https://imgur.com/a/dHQ5WyJ

Here we've basically zeroed out rent, mortgage, and everything else, in order to purely isolate the appreciation factor, and your calculator shows a year-30 range of $1m +/- 285k at 95% confidence.

However, if you take 30 independent draws using a 0% +/- 3.2% range @ 95% confidence, that implies each draw has 1.63% std deviation (3.2% / 1.96).

The 95% CI for the sum of 30 independent draws with 1.63% stddev is given by (1.63% * sqrt(30) * 1.96) = +/- 17.5% return.

Applied to your initial amount, I'd expect to see a $1m +/- $1m * e^(17.5%) = ~$190k range for the 95% CI, not the +/- $285k range that you show.

Note the power of just using basic stats and identifying edge cases to validate whether your simulation is giving reasonable results -- here I think either an input or output might be mislabeled (is the input really 3.2% at 95% CI, or is a different confidence?).

While I agree in principle, unless people are becoming unchained from their ISP-provided router/modems, I just don't see this gaining much traction. I really hope this succeeds (or something like it), I just feel that the current ISP environment is not conducive to such disruption, especially when 98% of users are running vendor-provided modems with the default configuration.

The N64 to me is arguably an outlier in console design in terms of how well it has aged. The console unit anyway; a controller for three handed humans still makes as little sense to me today as it did back then. Thankfully history seems to have agreed as the idea arguably died with the N64.

Other than perhaps the original PlayStation, almost all old gaming hardware has aged far worse than the original iPhone’s industrial design in my eyes. It’s also industry trends I’d argue that aged that design of the iPhone as much as the design itself. Modern phones are typically much larger screened devices than what the market expected in 2007ish. A console is still just a plastic box with ports we shove under a TV much as it was in the 90s.
To contextualise, my comment absolutely assumed a modern desktop target.

Depends on what you're trying to do.

Are you putting a trained inference model into production as a product? Is it a RL system (completely different architecture than an inference system)? Are you trying to build a model with your application data from scratch? Are you doing NLP or CV?

As a rule of thumb I look at the event diagram of the application/systems you're trying to implement ML into, which should tell you how to structure your data workflows in line with the existing data flows of the application. If it's strictly a constrained research effort then pipelines are less important, so go with what's fast and easy to document/read.

Generally speaking, you want your ML/DS/DE systems to be loosely coupled to your application data structures - with well defined RPC standards informed by the data team. I generally hate data pooling, but if we're talking about pooling 15 microservices vs pooling 15 monoliths, then the microservices pooling might be necessary.

Realistically this ends up being a business decision based on organizational complexity.
I have no need for your parts, but cheers for keeping a line of products out of landfill for a little while longer.
Then you redeploy everything. But you're making that call based on risk, not due to a technical requirement.

One thing: one really can't talk about "China" qua society, or "Chinese" qua ethnicity, in this context. While there's a long, long tradition of talking about Zhongguo 中國 ("the Middle Kingdom", though its original meaning was closer to "the states of the Central [Plain]"), and asserting monoculturalism, in reality Chinese regionalism has always been really pronounced -- hence the reality that when spoken, Chinese "dialects" (like Putonghua/Mandarin and Cantonese) are actually more different, and less mutually intelligible, than European Romance languages. (And it goes beyond language -- think regional cuisines. As further illustration, eespecially if you look at Warring States period cultures, there's actually a stark difference between the traditions of the northern plain and of the south, esp. the state of Chu 楚 -- you can even see it, obviously, in their art and artifacts. The aesthetic are wildly different.)

Now, you could argue that Taiwan represented a Chinese conquest of indigenous peoples. But even before the island was annexed (during the Qing dynasty, in 1683 CE) there had been fishermen and pirates from the mainland (and Japan) operating there to some degree.

Ultimately, you have various populations leaving the Asian mainland at different times. Sometimes later populations intermixed/intermarried with populations that had arrived in outlying territories earlier, sometimes they displaced them; usually it was a combination of both. But it wasn't some monolithic ethno-state exploiting a technological advantage to expand its reach -- the reality was much more complicated.

One of the things that worries me about the current approaches to improving schools is that we focus so much on ensuring a minimum standard for all students to meet. I think for the future of the country, we should care much more about ensuring that exceptional students are allowed to excel. An exceptional student from a wealthy background will get the extra support they need, but we need a system where exceptional students from any background are able to reach their real potential.

If something like personalized learning can be made to work, it really has a ton of potential to realize this vision. It's a major project to really get this right though. Not sure if Summit has the right approach, but this article doesn't talk at all about what they're actually doing. It would be nice to see some much more thoughtful criticism.
As others have mentioned this is a very interesting side gig. How did you find leads on these companies to turn this profitable though? I imagine any company that does this sort of research would have to be relatively forward thinking.

You're still blocked from using later features potentially even reaching a dependency chain deadlock until you update.

Systems like this work far better when you just work to not break backwards compatibility full stop.

Similarly, they work better when you don't tangle up dependencies in a bunch of shared code, generated or otherwise.
Sure, but that's lower level than COM or WinRT. And in practice, does anyone embed, say, a Node.js module inside a JVM application via a C library?
Low wages are a symptom of government control, no other reason.

In a "true" free-market, whatever that is, there would be no low wages? This seems counter-intuitive. Do you have any evidence or reasoning for this?
Apart from issues pertaining timestamp granularity and clock skew, there is a problem that is technically not about timestamps but is related since it's often a consequence of the dependency data model employed by that class of build systems.

Consider this makefile rule:

foo.a: $(patsubst %.c,%.o,$(wildcard *.c))

Now, the foo.a target will be considered as stale if any of timestamps of it's dependencies is newer than foo.a

But what if you remove a .c file?

As build systems like make don't capture a fingerprint of the names of the inputs of a built (let alone the hash of their contents) it's very hard for them to deal with that case correctly.

Correctness is important otherwise your trust in the incremental builds quicky erodes and you start doing clean builds all the times you get an error, just in case.

The thing I love about woodworking (I’m not the op) is the upfront planning and design process, the immaculate attention to detail (an 1/8” off is often a big deal), and then the satisfaction at the end of being able to physically hold the finished product.

For commonality with software, personally, I like to do a fair bit of up-front design work before building something. Not days worth for most stuff, but hours worth. Scribble ideas, riff on them, iterate to a design I like before building it. And then during the build process, you’ll probably discover something you missed in the design process and have to improvise a bit; software is generally more forgiving in this regard, but it’s the same shape of process.

I find that when I’ve been doing more hands on stuff (small woodworking, welding, car repair, bigger construction), I get better at doing the software design stuff. My brain gets better at thinking through the consequences of design decisions and picking out small details that can have significant implications.

And I'd agree. But the N64 still functions exactly the same today as it did when it was released. It still does it's job. It will still entertain 1-4 players. Same with the S/NES.

Only if you define cash flow as the goal of the economy and production. If instead it is to provide food, shelter, and services, there is no need to speculate on how effective the (non extant) invisible hand is because it is evidently failing.

Three things for me:

1) I own a small rental property in Florida that is fairly low maintenance and pays for the mortgage + a small amount each month on average. This is a long-term ROI play since after taxes, maintenance, repairs, and everything else it ends up being close to a wash until the principal to interest ratio on the mortgage payments improves after 5+ years. I only say this because everyone and their brother in my age group seems to want to retire on rental properties, but in reality it's really not that great.

2) Basic ETF investing in a combination of value-oriented and dividend-oriented ETFs. This is, in my opinion, the only way to get truly passive income with literally zero ongoing effort.

3) I design and 3D print props and cosplay pieces on a referral basis for commission. In reality it's a horrible way to make money since quality 3D modelling for 3D printing is time consuming to the point of the hourly effective rate being lower than minimum wage, but I enjoy it, so it's kind of a semi-paid hobby.

I don't even want 200k worth of options. I want cash bonuses from delivering the features that sign profitable customers with a speed that my bosses think is improbable.

I am happy to be paid out of the money that I went out and brought in, but every company I have talked to is incredibly allergic to any suggestion that I be paid real money for the value I deliver. Each time I have offered to take the low base offered but with 0 options and a cash bonus system based on directly attributable sales, the company comes back with not a culture fit and declines to proceed.

I am freelancing right now while I look for a job and find it very frustrating to work as a contractor selling turnkey business problem solutions to startups (complete apps, setup CI, sso, add permissions to existing app) and have them not even negotiate quotes for day rate of 1.6k, but then when I offer to focus exclusively on a single business as an employee then suddenly they can only see 1/3rd the value in the same work!

I feel stuck where as an employee I am viewed as a replaceable cog who is not worth the extra time to even think about giving out bonuses, while as a brand new contractor I am not yet proven/connected enough to consistently fill the pipeline.
