A few ideas:

* assuming they have computers with the internet, you may try to integrate some online self-paced web-based interactive training. This will leverage massive existing efforts.

* ideally there could be multiple tracks/programs in the same class for people at different levels or interests. this is much more practical if you have some way to do self-paced learning

* you might include something like Slack or Discord or some online site briefly. unless this category is something kids are already experts on

* spreadsheets and word processing seem very important and maybe are the mandatory part you try to get everyone through

* programming, AI and/or robotics would be nice to include some self-paced exercises for an advanced optional track. Again, lots of websites for this stuff.

* Many kids are interested in streaming. "How to get started on Twitch"

* "How to Google" https://www.google.com/amp/s/amp.businessinsider.com/how-to-...

* 3D modeling, basic video editing, Adobe stuff (websites/Blender)

I guess my answer is, ideally, Everything, self-paced or maybe small-group-paced. Maybe hard to do that, but I think if they are allowed to self-direct to some extent and have different options then they will get much more out of it. Maybe everyone does WP/spreadsheets or whatever basic stuff and then they have to pick a secondary track once they get through that.
> It entirely depends on manufacturer but I've heard of some actually seeking out open networks for internet access if you don't configure their Wi-Fi. Some people reported an unconnected TV suddenly prompted to update because the neighbour's wifi was unsecured. If you can, I'd set up a specific SSID with no LAN or WAN access just in case.

They probably will use 5G cellphone service eventually...
You hit the nail on the head. So many people today will never escape their debts or achieve financial independence because they were deprived of financial knowledge until it was too late.

Software Development - Especially in the inner city.

I really wish there was a way for engineers to help public schools educate students in software development. Years ago, I offered to teach a class at my old high school, and even _tried_ to donate $5,000 to help fund it. Not only was it rejected, but the people working there seem not to care.

This was a school in North Philadelphia.

IDK, some part of me finds string theory at least more intuitive than "dark energy". But I'm not an expert.
I don't think the trick is the Rayleigh scattering, I think it's the parallel rays. Notice how all the pictures have well defined shadows of parallel rays?
You too?

I've got Prince of Darkness, The Void, Mandy, and the soon to come Color out of Space on my watch list. I'm pretty sure I've seen most of the rest high quality stuff. Annihilation, etc...
Have you tried buying higher CRI LEDs? Halogens have very good color rendering compared to typical LEDs (100 vs ~80 for typical LEDs), but you can buy specialty bulbs with closer-to-natural spectra. I haven't dug much into off the shelf options, but one of my coworkers did and got excited about these lights: https://store.yujiintl.com/collections/high-cri-led-lights/p...
100% social skills and assertiveness. Everyone should be helped to a level playing field there as much as possible and as soon as possible.
How computer programs work in operating systems. What is I/O, virtual memory, how does a filesystem work, what are software libraries, system calls, IPC, TCP/IP, authentication and authorization, how do kernel drivers work, how do programs and operating systems store settings, etc. Later, how web applications, smartphone apps, databases, encryption work.

The purpose is to be able to reason about how computers work in general. It's similar to teaching people how cars or plumbing works; they may not be able to build it, but they could conceivably troubleshoot and attempt to repair it, and it makes tech jobs easier.
Scientific method. I'm not being presumptuous.

When coming across a problem, I type out all hypotheses on a notepad.

Microphone doesn't work on app? Is it this device specifically? Is it the file system? Faulty recording code? Null pointer somewhere?

Then I find the simplest, hackiest way to (dis)prove the hypothesis. Be sure to narrow down the test as far as possible.

What a lot of people do is just bash random things, often the simplest hypothesis, repeat that same thing for half an hour, do something else, then repeat what they tried earlier. Or in somewhat tougher problems like pathfinding, where each hypothesis takes an hour to test, a lot of people get intimidated and procrastinate.
I was thinking about that. Putting a microsun in your peripheral vision? Can't that mess with your eyes in the long run?
Projectors are also an option.
I find a lot of people, even developers, have no idea about the history of computing. Things like where Unix came from and why our computing world looks the way it does today. Talk about mainframes, Alan Turing, ENIAC, etc. Also a discussion on the Unix way vs the Lisp way (NJ School vs MIT School) should be informative. Impress upon the students that the computing world we live in today is mostly an accident, things could have been very different: we could have all been using Lisp machines, for example.
> Other than “we’ve been doing it for a while,” there seems to be no reason to expect that being in a 100x dimmer environment all day wouldn’t be awful. Indoor darkness seems to be one of those things that we don’t question only because it’s been that way forever.

An interesting question is: what average light levels existed in the Environment of Evolutionary Adaptedness for humans, given the types of things our ancestors spent their days doing?

Consider: many humans were savannah persistence-hunters; but many humans were also jungle and arboreal-forest gatherers. And either way, we probably liked to find trees to climb and use as protection, when we could (as chimps do.)

So, given that, are human brains calibrated for "sun-baked African plains" daytime brightness, or "under a forest canopy" daytime brightness, or somewhere in between?
That was a fun read and I was a bit shocked that they didn't have any suggestions on remediations. Not saying they should have as the topic was bit rot not how to fix it.
“Philosophy of science,” or, “how do we know something to be true, and what is the difference between knowing something and believing something to be true?”

I took such a philosophy course in college and it was quite informative as a way to reason about problems. It helped me with my debugging, to move from “x is the problem” to “I believe x is the problem, and here is why I believe this causal relationship exists.”

I think this is what most of us call “critical reasoning” skills, or “how to think.” But this particular line of causality, and analyzing the strongest statement one could make based on a set of premises, is a skill that has served me well as an engineer.

Did the CRI for the LEDs you bought match that which was listed or did they even have a CRI stated? I'm willing to spend extra for high CRI but so much junk on Amazon outright lies about being UL listed, it wouldn't surprise me if they started lying about CRI once they realize it is a selling point.
In addition to the great suggestions below, one of the things I would add ( this gels with the whole problem solving skills suggestion) is to introduce them to algorithms. It needn't even be in a specific language. Being able to think abstractly is one of the great powers that high schoolers should be exposed to.
I would listen to what they want to build and cater the curriculum to that. Make it democratic and cutting edge and personalized.
That would be equal to x^y, which means that the solution is the y'th root of y?

However, don't you have to prove that the series converges? Is the approach even valid if it doesn't?

I think if both of those went under it looks extremely bad but SoftBank Group gets a dividend from the SoftBank Corp (telecom) that has enough dependable operating income that should be good for servicing debt. Additionally, SoftBank Group is still trading at a discount to its BABA stake + everything else.

There definitely is an increasing chance of a perfect storm where multiple bad things happen that could quickly evaporate this whole thing:

- China gets worse domestically with or without trade war ratcheting up and BABA is collateral damage

- S/TMUS merger fails from domestic regulatory pressure (just had TX and NV AGs settle but other states are not on board still)

- UBER, WEWORK, and others (Oyo?) get dragged and there are some feedback loops on other portfolio companies

- Funding pressures. There was an article on FT about domestic banks being skeptical on lending more to SOFTBK. Stuff like that becomes a self-fulfilling prophecy after a while and can quickly spiral out of control. That said, SOFTBK has something like 20bn cash on hand so that should only really become a problem if there's prolonged weakness.

- Vision Fund 2 more than likely not going to be able to raise its envisioned amount. Obviously no one wants to touch this right now. I think there's definitely been internal discussions on how some of this $ would be used to bail out VF1 portfolio companies through acquisitions. Additionally, if I had to make a forecast, there's not enough companies out there right now that could absorb $100bn of VC money and be able to profitably exit.

I think the biggest problem going on right now is that all of these companies were built upon endlessly flowing capital and business models were based on that. Now that everyone is focused on "profitability", I'm not sure if you can easily pivot some of these business models without completely imploding businesses. None of these companies have created anything that consumers cannot live without. VC-subsidized luxuries brought to the masses can have a very fleeting existence; people got around before UBER. If any of these companies ever try to raise prices in an attempt to display profitability, they could be in a rude awakening for ECON101 price elasticity/inelasticity lesson.

Both options can coincide.
I absolutely hate LEDs. I don't know why, but I just hate them. Especially the white ones.

The yellower are similar to a mid summer day and I can cope with them, but there's always this feeling of something being off. I guess it's connected to us humans being used to non-sun light being (similar to) a fire - mainly consisting of yellow/orange tones.

Also, I don't exactly remember from where I read this, but when a (town) changed the street lights to LED's, a lot of people started having sleep problems, and it supposedly was connected to the blue light emmiting properties of (lower quality?) LEDs.
I know someone who did setup ceph just for it's healing capabilities.. but of course one has to familiarize with all of it's administration aspects for that.

Setups with RAID1 could help fixing bit rot, but I think these setups are not full stack tested, so one would have to play and test by oneself (and after soft ware updates verify the whole stack again..).

Maybe easiest remedy is to keep all files in a second directory, and hope that when bit rot invalidates one version of the file the second one is ok. rsync could in cycles sync the 2 directory trees.
Well it doesn't appear to be publicly available yet, so we'll have to wait to find out if this is real or just smoke and mirrors.

Mostly agree. My go to language is python. Used c# in last job and it improved much over past few years.

When I need blinding speed I can use nuitka to compile python scripts.

On the rare occasions needing speed and cross platform coupled with my lessons to avoid wasted effort I turn to Lazarus/fpc because code is simple and Lazarus takes care of the target platform stuff so I don't have to.

For IOT bare-metal stuff you can't go past C. It just works and after learning it's quirks you will see how other IOT tools are largely hacks or compromises to avoid learning C.

What is actually going on in the world. I am very grateful my tech teacher in high school always started class with ten minutes of discussion about current events. Some of the time he would bring in a newspaper and for a headline, other times he had some other idea in mind. Much of the discussion was about our thoughts on the subject though, not just a recounting of the events.
For an 'Information and Communications Technology' course, I think the main goal ought to be demystifying computers and the internet, to enable students to think critically about about the role they play in society.

One outcome is that students can be active users rather than passive consumers and think critically about topics such as privacy and social media.

Other outcomes are improved computer literacy, and perhaps inspiring some students to pursue computing as a hobby or career -- but the demystification and critical thinking will benefit all of the students, not just the ones who are interested in computers.
As someone who was always interested in CS but who also always sucked at math, the basics of logic helped me immensely in finally understanding both. And, whether by nature or nurture, as a woman I was always better with words than numbers. Learning the fundamental concepts of logic without numbers bridged that gap in my brain and gave me the confidence to tackle the numbers soon after.

There’s a really good course on edX called “Logic and Computational Thinking”. It’s pretty basic and you could probably finish the whole thing in a Saturday. I would imagine much of the content is in line with the capability of the average high schooler. It was a good (and unintimidating) starting point for learning how computers “think”.
Alternatively, they might be renting expensive GPUs, and they are trying to minimize how many they are running in parallel. 24 hour turnaround probably lets them run each generation consecutively.
Furniture, flooring and carpeting contribute towards indoor air pollution. For example, glues used in laminate flooring can release formaldehyde into the air for decades at room temperature or warmer.
I am thankful for a wonderful family. We have our moments of despair but I don't know where I would be without a loving wife and an overly curious 5 year old kid :)

It could be different for everyone. My ancestors likely grew up in dense equatorial jungles and caves, not plains. A lot of my family members perform much better in dim light. My optimal seems to be 2-7 PM on a rainy day.

Yes, and that is because Google is actively pursuing all the ways they can to break user's ability to block ads.

That’s unfortunate because it would be interesting to compare virtualized V100 GPU with real hardware 1080Ti. On paper, the two are pretty close. If that’s true in practice, you can use https://vast.ai to reduce the cost by a factor of ~5, i.e. it will only cost about $350.

OK, looking at the comments, I have to note that Dark Matter[1] and Dark Energy[2] are two different but related hypotheses. The basic existence of Dark Matter is on a fairly strong footing experimentally and afaik this article doesn't cast doubt on its existence (it has been observed, on the cosmic scale, as accurately as many form ordinary matter, for example). Again, this is the dark energy issue. Just sayin'

Python I think needs a distinction. It’s an A for small projects that can be owned by a single person. But a C for projects large enough to warrant multiple developers. Dynamic languages don’t scale without a huge amount of extra tooling.

Hmm, that's sounds interesting and is at least an avenue to chase down. Sadly, next to my stockpile of halogen bulbs, I also basically have a lifetime supply of LEDs and CFLs that didn't pass muster. Maybe someday I'll have a really big garage that needs lighting. ;-)

The specific bulbs you linked to have a crazy high lumen rating, which appeals to me despite their high price.

I have noticed that name brand (and pricier) LEDs tend to do better for me. Some of the ones from e.g. Phillips and Osram put out a different quality of light (though it's still not up there with incandescents for me).

Not the best example, Galileo argued plenty from positions he saw as intuitive, even though he was completely wrong.

Also, according to the physics of the day, its completely understandable as to why they thought that way, intuition comes from observing nature, even if those observations may be incorrect simply from not being able to gather the data properly.
This is almost certainly going to be proprietary, so it's nothing to hold your breath over.
