>What fraction of their online time should I sit with them?

Unless they're 5 year old and learning the ropes or asking for it, then none

>Do I play all video games with them or should they have some of "their own"?

If they want to play with you: as much as you want, otherwise none.(I kinda wish I played with my parents honestly, but they never cared)

>Do I give them the ability to do online purchases?

Physical products? Probably yes, but it should go through you to check that the site is not a scam or shady.
Virtual items, crappy lootboxes and predatory subscriptions? Absolutely not.

>Do I allow them to use up all of their money even as a mistake, or do I set up a limit?

Depends on how much money you have.

>Do I limit their "screen time" (hate that term) or will that prevent them from interacting with their friends in the way they would want to?

No, I don't see the point. I spent hours doing programming exercises in freaking notebooks because my parents were soo keen on limiting my screen time. Dozens of arguments because they would take away my consoles. Not worth it.

Also I'm not really in favor of trying to control what your children do, but block TikTok if it still exists in 5 years, some social medias aren't social medias, they're psychological warfare.
But... How?

They might know that Vlad is going to gate Los Angeles at gate A5. But, even assuming this display is not precise, how are they going to know that I'm Vlad?

They will know that someone around them matches that information, but airports are generally busy places. Especially with new technology that people would want to try out.

"Well specified" regulation is also a weapon. No law is fully unambiguous, clear and without conflicts with other laws for a specific situation, more well specified a regulation is, more you need professional expertise to decode, understand, implement and certify it.
Do you have a reference for the definition of this energy storage unit? I have never heard of it before and my attempts at searching the web seem to contradict you.

Wikipedia writes: “Storage capacity is the amount of energy extracted from an energy storage device or system; usually measured in joules or kilowatt-hours and their multiples”

https://world-nuclear.org/information-library/current-and-fu... writes: “Storage systems for electricity include battery, flywheel, compressed air, and pumped hydro storage. Any systems are limited in the total amount of energy they can store. Their energy capacity is expressed in megawatt-hours (MWh), and the power, or maximum output at a given time, is expressed in megawatts of electric power (MW or MWe).”

Both of which to my layman reading opposes your claim.

There's a similar project at MIT call App Inventor http://www.appinventor.mit.edu/ which uses a graphical Scratch-like environment to build Android apps. I can't tell if the two projects share code, but they certainly share philosophy and approach.

I found App Inventor actually quite a practical way to write small useful Android apps. Certainly better than loading squigabytes of IDE/library/emulator/etc and fighting with the Android build system. (This from someone with plenty of code-cutting history!)

I wouldn't use App Inventor for anything big, but for small projects, have a look.

I agree, my 7 year old is into maths at the moment and he found it easier to just use PHP to do basic maths.

I sat down with him for about an hour and I printed a "cheat sheet" for the various arithmetic operators (just the basic ones) and he's now quite able to just whack a simple script together and execute it on the command line.

Having said that, he wasn't entering the situation completely blind. He's been using a PC with Linux (Ubuntu) since he was 3 years old. He's been playing Minecraft for 4 years (which is excellent for younger kids to learn mouse skills).

I also started him out on GCompris on a laptop. Then we both built a PC for him when he was 5. I got a load of cheap second parts during the early part of the pandemic and I let him do it himself (while observing and guiding).

I started him early because I started early too and I started him off on PHP because I remember it being relatively easy to learn when I was a kid because it isn't a particularly strict language which means a young mind doesn't have to perform a huge amount of translation in their own head, they can almost type exactly what they're thinking and run it.

The command line I introduced almost immediately. It was a way easier method of teaching him to launch apps without my help...I just set the terminal to load on startup and printed him another "cheatsheet" of basic stuff that he needed (no rm -rf * just yet).

If he's in an exploratory mood he will use the menus and UI but if he just wants to get straight into Minecraft or write a script he can just get stuck in!

I can see scratch becoming more interesting to him further down the line but for now, certain things are easy enough.

Typing is an interesting one though...I spent a fair bit of time working on his typing because his handwriting at school wasn't up to par (he's fine now, but his crap handwriting was holding his spelling back a bit). As soon as he became somewhat proficient at typing his spelling improved no end. Unfortunately though, his teacher won't let him do spelling tests on a laptop. Which I think in 2022 is the dumbest thing ever. They've only just started teaching typing and basic computer skills in his class (as of about 6 mo this ago). I had his teacher take me aside and ask me exactly what the hell I did to get him so far ahead. They measured his typing speed at 60wpm!

This all said though, I am an IT guy...so parents with little to no tech skills might not have the smooth ride I had, which is probably where tools like scratch come in...I think it's a tool for non-technical parents as well as kids.

Before scratch though, I'd highly recommend GCompris...but be warned, you need to do it short sessions (20 minutes or so) because kids get bored of it fast.

My youngest is 3 and he's getting second knowledge from my oldest right now as well as the same stuff I did with my oldest...so maybe he'll learn even quicker?? We'll have to wait and see.

Regarding privatization, we could easily require private companies to put up a bond/insurance for the cleanup so they pay for it ahead of time thus preventing issues if they go bankrupt. I say “easily” because passing anti-nuclear regulation seems to be the one thing the US federal government can get done effectively.
Jack Ma is just one example. The CCP went after celebrities more recently. No individual or organisation in China should be allowed to be more popular (or powerful) than the CCP in their view. That's why they went after Falun Gong decades ago - it had more practitioners than the CCP had members.

> since they're worse than a warehouse job, and Amazon pays so well

Not all warehouse jobs are equally terrible, as evidenced by the people working at warehouses other than Amazon's at lower wages. Amazon pays above the going rate for warehouse workers because of its reputation w.r.t. worker conditions.
I noticed that (the) Manicongo has some folkloric fame in afro-Brazilian culture, the/his name is mentioned in songs and seems to persist in the collective memory. I'd love to know if it's the Manicongo mentioned on these maps that people remember, or if it's the more general title ("king of the congo"), and if there's any story behind this persistent folk knowledge.

Wikipedia is thin on details, perhaps some Brazilian HN members can chime in here?
No, the Central Banks give banks cash in return for garbage mortgages.

Look at the giant bump in 2008 in Fed assets. Most of that is mortgages.

And then in 2019 an even bigger calamity.

Those massive jumps represent the finantialization of the USA, a massive form of economic shift.

I am not a parent, by I think there are kids that are interested in computers and programming, and kids that are not. That's the divide between users and makers. That does not mean they can't be creative with something else.

So it's a good thing to try to show them how the magic happens, but being too persistent is pointless.
Code Club World - Introduction to Scratch
A gentle introduction to scratch and python from the Raspberry Pi Foundation.
I’m not Godel, but my ad absurdum was meant to be slightly weirder than the objection that seems to have come across. I’ll try this way.

I had a flash of a question about whether the external information required in either case offsets the information provided by the objects in the proof (implicitly, explicitly, or artificially). I was thinking in terms of both formal logic and entropy, loosely.

The (usefully simple) construction here implies use of a compass or string. In a sense, the physical constraints of a compass encode the same information as the lemmas and theorems do abstractly.

“Brah, you should google metaphysics and Bertrand Russell,” is probably about right But, I’m sure there is a term that I just don’t know or can’t recall.

You make the claim, so you produce the evidence to support it.
Since it is from the constructionist tradition, I believe it is intended as a "microworld" [1] so being powerful and general purpose is an anti-goal. It is optimized for trial-and-error exploration, which works best when the functionality is reduced and there are not too many tools in the shed.

Producing text and formatting strings is likely deemed out of scope for that reason. People figuring out clever workarounds is a bonus!

I’m on full take with both NSA and GHCQ minimum. I cut power to hardware when I want privacy. My ex-girlfriend is CIA, but uncle works for a defense contractor, and just for fun: I’m one of 10 or 20 colorful figures in tech who make a great story in the last ten years.

Have I seen shit? Yeah! Are you full of shit? Also yeah, unfortunately.
I'll be dead-honest with you: I think most of the security-posters and privacy-posters on this site are doing so by ostentatiously cargo-culting. So none of the concerns any of you espouse about this stuff bothers me. I literally don't believe you guys believe this and if you do, I don't trust your competence in arriving at that conclusion logically. So, no, I'm willing to implement lots of stuff because I want it to exist.
> Don't write code to handle random bitflips

It depends what you're doing. There's no fixed threshold for "errors that you should handle" so smackeyacky is right - handle the errors you can (but don't spend an inordinate amount of time handling very unlikely errors).

Bitflips are not very unlikely on huge systems so you need to handle them.

In my experience trying to distinguish between "expected" or "normal" errors and "unexpected" or "exceptional" errors is pointless and impossible. It's better to think about the likelihood of errors.
>After billions of dollars, the scaremongering horror stories about "side effects" and "long term effects" have of course never eventuated.

Never eventuated, like you mean Astrazeneca was never suspended in eighteen countries on three continents? and Nordics never suspended Moderna?

That never happened in your reality? Wild.

Human robots and robot training (aka military, police, medical, fire) are still the states best assets for controlling the already present threat to the countries borders ie the population, as well as foreign countries and their array of human robots. However drones like those mentioned in this article, do not suffer from human problems like the Chinese Whispers/Telephone/transmission chain experiments in the same way humans do, they can also lie dormant outside the normal confines of a sustainable human environment, ie food, shelter, sewage, etc. If nuclear powered drone's dont exist here before 2050 or even today, I'd be very surprised considering the obviious nuclear powered subs, how the placement of land based nuclear power stations are predominantly on the edge of water bodies, like lakes and sea's. The out of sight out of mind attitude with decisions makers, as seen with sewage outlets into rivers and sea's is another example of their thinking. Air based nuclear powered drones are not out of sight or mind, excluding the nuclear powered satellites which will burn up on entry, dissipating their nuclear radiation over a wider area, hopefully not triggering any of the radiation sensors placed around various countries.

But pattern recognition is an AI's best friend, I wonder if NOAA's NDBC (https://en.wikipedia.org/wiki/National_Data_Buoy_Center) have detected anomalies over the long term when considering these are drone's in all but name, powering sites like https://magicseaweed.com/
Employers should not and can not apply consequences for any reason they like. You could say “you are free to wear any color shirt you like, but if you pick the wrong one, you could be fired”.

That may be true in America but it isn’t in other countries. Arguably some speech on social media should be protected and not a reason for employment termination.
YAML originally stood for "Yet Another Markup Language" until somebody pointed out that it wasn't actually a markup language, so they retro-named it "YAML Ain't Markup Language".
Those will be among the targets in the first strike. Unless they can fire before the nukes hit they're not useful. Subs are pretty much the only option.

I suspect foreign agents try to bribe people in submarine crews to sabotage their sub in the event of a strike. If someone onboard could stop the American second strike missiles being fired they'd give Russia a huge advantage. I imagine the Navy have considerer this.
In C++ for example there’s an exception hierarchy and several classes of errors similar to what you enumerated, so the handler might catch a specific exception as a more generic one. There’s also … which catches all exceptions.

This is fine, as one has the choice of exposing error details to outside code or not.
The Czech taxation authority has the "Automated Tax Information System" as the primary IS.

> China is way more innovative than much of Europe for example

Of course they are, having built upon stolen EU and US tech and having trained their people in the West. But they learn fast and incrementally improve those designs. The difference is the Russians had their very own designs. Even in electronics, their concepts are fundamentally different from western concepts.
This catch and ignore seems to be straight out of the (sadly not real) Visual Basic design patterns book :-)
Exactly, thank you. At the time I was transitioning from a jack of all trades person to strictly a programmer. I despise getting called in the middle of the night.

My feeling is that, if you have a foundational business process like this, it should be designed to be maintained if there is a serious problem, and it ought to keep working. I know, haha, "the Internet is a series of tubes" but I really wanted this thing to be like a chunk of very uninteresting ductwork that just moves air from one place to another: it should just do its job with as much fanfare.
I was a believer in the "my code should never crash, no matter what" school of thought until I shipped a Dreamcast game with an out-of-date opening cutscene.

It was an in-engine opening cutscene which was very nearly final; the file we shipped was about two or three weeks out of date compared against the version that should have gone on the disc (It had one missing shape key on a character's face at the end of a shot, and a couple other missing elements). My code was wrangling the whole animation; doing all the stuff which our at-the-time-primitive animation system couldn't do itself (animating texture coordinates and etc). And my code was just silently handling all the errors it ran into so that we never even noticed that anything was wrong.

The difference was subtle enough that in the twelve years since the game was released, nobody but the original animator has ever noticed and mentioned it to me (and that, years after release). But that one experience and knowing how much worse it could have been was enough to convince me that "crashes early and crashes loudly with as much detail as possible" is by far the better strategy. At least for entertainment products. And doubly so for entertainment products which can't be patched after release.

(for clarity, this screw-up was 100% my fault. The animators had made the final changes to the cutscene data files in plenty of time for inclusion in the final build, I just somehow didn't import the changed data files into the game when I made the matching changes to the code side, and then my code didn't throw any errors to tell me or anyone else on the project that anything was wrong.)
Pretty much, ripping through my city now. There isn't a lot of sentiment for liberty/freedoms here, so the authoritarians had a field day. We'll probably do it all again next time too.

China’s population is double that of Europe, so China would need to produce twice the quantity of innovation to be comparably innovative. I’m not saying it doesn’t achieve this, but we should be wary of comparing two places with vastly different populations.

> But when done right, as it was in China after the 90s and before the Pooh, it has also caused the single biggest reduction in poverty in world history, measured by number of people.

This was largely China moving away from a planned economy and toward a more market oriented economy. Also, you have to take care about how you measure “largest reduction in poverty” here as well because poverty was declining all over the world at the same time, largely driven by advancements from the capitalist west and globalization. I’m sure economic planning can be credited with something, but the key element was “allowing western money to pour into the country” which looks a lot more like capitalism than central planning to my eyes.
Garbage collector?
Do you perchance have a reference for that?
This is exactly what I was after thank you!
What an excellent, insightful post. This really resonates:

"when self-promotion is done right, it never looks like self-promotion"

Blatant self-promotion manages to cause a visceral reaction in me, but as you note when someone is doing it obliquely then it just becomes an overall part of the story (indeed you the author are doing that a bit here which I wouldn't have even really noticed had you not mentioned it).

I'm part of an online community that recently had someone come in, manage to get an admin role and start self-promoting the heck out of themselves and their project. My initial reaction was to take my ball and go home. But some more even-minded folks helped me understand that really it is just, at its root, failed communication. The person likely has a real interest in helping and growing the community, but at the same time is balancing their interest/need to self-promote their own project. If their messaging were just a bit better and less explicit then it could come off in a completely different way.

Thanks for sharing such a great piece!
