Thank you for the feedback! Much appreciated.

Trust - Yes, I've collected some testimonials from other products (book, extension, Deschool program), but none about the course yet, since it's brand new. I'll work on this.

Video - Thank you. I'll plan on improving the course continuously. I'm more animated in some videos, but I'll re-record others.

This is the 1st version of the product. My background is programming, so I plan to update this as if it were a software product (it partially is).

Again, thank you for the feedback!

"Tesla has filed a patent detailing a new way to mine for the lithium necessary for batteries. The concept isn’t new; "

So which is it?
Yes, momentum is key. Without it, every little thing seems hard.
Tesla pretends the concept is new to get the patent. The concept isn't actually new.

Would be far from the first time patents were granted this way...
>According to Electrek, which has gotten hold of Tesla’s new patent

Aren't patents supposed to be public?
Thanks! We had a link to a document in the deck (in a very small font!) that goes into more detail on the work that led to TigerBeetle [1].

More performance allows you to trade expensive hardware for cheaper commodity hardware to gain lower operational cost (e.g. a cluster of three Raspberry Pi's) while still having more than enough headroom to handle volume spikes safely (e.g. Black Friday).

With digital payments, payments are also becoming more global, with higher volume and lower value, but existing infrastructure is not typically designed for this high volume low value performance profile (e.g. millions of payments at a fraction of a cent).

Finally, high throughput allows you to easily ingest huge amounts of historical data into TigerBeetle in a few seconds.

The design actually made this kind of throughput fairly easy to achieve, even for three small office laptops. The hard part is all the safety work that we're doing to make this hopefully many times safer than existing systems.

>If you are an American you may have heard of ATSC 3.0, perhaps by its marketing name of NextGen TV. Just like the DVB-T2 standard found in other parts of the world,

To those living in US, is ATSC 3.0 a thing yet?

It is funny it mention DVB-T2 as counter part in other parts of the world but for many part of EUR, DVB-T2 is now over a decade in use. Although the earlier DVB-T2 are stuck using AVC while Germany and France has newer DVB-T2 with HEVC variant.

Or do Americans generally dont care about Free to View TV and only use cables or any other Pay per view network?
What is the probability that 15=2*7?
The point is that there are many locations and situations where this is not really realistic, and that "more condensed housing" takes a century.

So practically and politically it is not possible to hit cars in general. Encourage alternatives where-ever possible but realise that there are not always alternatives and in those cases people should not be penalised for driving. Instead there should be support to transition to EV.
Often, the good just can’t cancel the bad. It doesn’t work that way.

I understand that suicide is hard on the people left behind, but I also understand that some people don’t want to continue to suffer to prevent others from suffering.

Suicide is a very hard step for people and although Futurama style suicide booths are a step way too far, there should be more humane avenues guided by medical professionals for people who are ‘done’.

Please if you do have suicidal thoughts, at least go to the doctor hand have a that about it, they can help you further.
You can compare Apple's 7NM chips, too, as I just said if you'd read. And guess what? The power consumption figures bode poorly for AMD.

The IO die only adds like ~15W btw, yes, I'm aware it's on a GlobalFoundries node.

Lastly, AMD's mobile chips throttle down to fairly low clocks and in AMD's case, low to modest performance when not plugged in, it's why you keep hearing tale of the great battery life on Zen 3 laptops.
Note that EU healthcare isn’t perfect either. For example, in the Netherlands, many diabetic care products offered by national healthcare is of the cheapest kind. My wife had these things that shoot a needle for a droplet of blood, and they were awful and crude, usually leaving a much larger hole than needed. She just bought her own to avoid having holes in her fingers. There’s also that thing you can put on your arm and read your blood sugar which is a great invention, but guess what: you have to pay for it yourself.

The “free” healthcare is great, but it’s not free comfortable healthcare.

IIRC the expensive insulin is the comfortable kind, that works better. The cheap insulin Americans can buy is the uncomfortable kind.
Simple Steps on How to Write an Excellent Research Paper
I resent that I have to spend a magnitude more effort to refute your misinformation than it took you to write.

You are conflating the person whose shipment was seized, Henrik Huseby in Norway, with the person reporting on the story, Louis Rossmann (two "n"). The full story is that Rossmann initially believed that the parts were refurbished, so of course they would bear the Apple logo. When new information came later to light that the parts that Huseby bought from ShenZhen Excellent E-Commerce Co. Ltd. (DBA jacktele.com) were counterfeit, then Rossmann made not one, not two, but five follow-up videos to correct himself and present the new information. That is because he actually cares about being truthful. Chronological order:

> there can only be one such function implementation per type

Right, and that's more than one definition per name. In Zig, a name refers to only one definition. (Plus, recall that in Zig the type of a target isn't always known when reading the code, probably more frequently than in C++ or Rust, where this only happens in macros.)

> disallows overloading of names

That the definition referred to by an identifier depends on the type is what overloading means. Overloading is the very essence of traits.

That's an interesting take.

Privacy, to my mind, boils down to consent. And consent - whether given or not - is a behaviorism informed by context. And individual may or may not consent based on cultural norms, values, beliefs, social cues, political, economical,... affordances and so on. Consent, on the part of the individual, becomes a trade off depending on the context.

Privacy is a social construct, and what makes it so hard to discuss is that the context defines it's interpretation. While debate tends to focus on the "right to privacy", what it actually pertains to is individual agency - or lack thereof - within specific contexts to give or deny consent.

The discussion in the article revolves around two specific hot-button takes of privacy: (a) consenting to the state knowing your whereabouts, and taking restrictive action (b) private businesses tracking consumers through digital technology to further commercial interests. And how both aspects have become intertwined with each other into complex social, economical and political issues in a globalized world.

While privacy can act as a class signifier that doesn't necessarily mean the modern, present-day interpretation of privacy as a class signifier is a permanent or universal fixture of social behavior (I don't think you implied this btw). Rather, industrialized societies specifically have adopted digital technology to a point where their normative context is heavily being reshaped, and existing and rising power structures come at odds as a result. Antonio Gramsci coined the concept of "cultural hegemony" to describe that dynamic in general terms. The discussion among sociologists, activists and political thinkers that spun out of this idea is probably more interesting.

https://en.wikipedia.org/wiki/Cultural_hegemony

Privacy as a class signifier is an interesting theory. But it only holds value if you can tie it to identifiable elites and power structures that can leverage privacy as such. Just reading through the HN comments already shows how difficult that is in itself: just defining the scope and breadth of the concept of "privacy" proves difficult as it requires you to be aware of your own context, and be able to suspend in your mind before reframing the notion within many different social contexts in order to get a good understanding of the hidden complexities.
Exactly my viewpoint!

The industry prevalence, the community size, the installed codebase size, C compatibility, ability to write code at any level of abstraction, etc. makes C++ THE "Industrial Language" to learn.

I keep telling everybody to learn C and C++ irrespective of whatever else they might be forced to study/use since these literally gives them the ability to work at any level in the Software Stack; C is the "universal glue language" and C++ is the all-encompassing monster :-). Bored writing User mode Applications? Jump into writing Libraries/Frameworks/Kernel/Bare-metal code; all using the same familiar language and toolchains. Familiarity trumps everything else. I myself have successfully transitioned from writing Windows desktop apps(16/32-bit) to Network Protocol state machines to Kernel drivers and Bare-metal MCU code all using C/C++.

"Modern C++" (C++11 and later) has shifted the learning goalposts somewhat but nevertheless all the pre-C++11 knowledge is still the bedrock on which to build the new edifices. As a side-note, i completely disagree with people (mainly the "Modern C++" proponents) trying to divorce C++ from its C roots.

Other than C++, the only other language i am willing to spend time on from a professional/industrial pov is Erlang due to its concurrent/distributed/fault-tolerant features.
But that doesn’t really help you remember 91, because the number is not part of the rhyme.
Tips for New Domestic and Commercial Plumbers

Apparently it's an US problem. Never heard of insulin as a costly drug in Europe. US health care system is totally broken with costs 10x for most procedures without any reason.
Agreed, but for me there have been a few more reasons than boredom. Broadly I see 3 reasons I’ve procrastinated in the past.

1. I’m bored, and not learning anything new, just doing the same thing over and over.

2. I don’t see where this is going, or the point of doing it. Felt this a lot with university assignments in particular.

3. I’m afraid. This is the only one where I think it’s worth persisting. Sometimes something is new and scary, like public speaking or deploying to production for the first time. In this case, what I’ve found to work really well is to just sit with the fear, observe the sensations it produces in the body, and then it naturally just sort of weakens.

For 1 and 2, I think the procrastination is actually telling you something important.

I have my home server/router running Arch, update maybe 5 times per year, only one time a non-critical service(redis) failed to start due to a default config option change. I originally meant to run Debian on that, but when I bought the hardware, it's pretty exotic for Debian's old kernel, and Arch ran great.

I also have a Pi2 running Arch ARM at my mom's house, doing one or two updates per year when I visit her, also failed only once, and that's because of a corrupted SD card.

I'd admit I'm usually a bit nervous typing pacman -Syu on those two, but it's doing surprisingly great.
I find it surprising that anyone could imagine that the creator of C++ is unaware of its issues.

I’m sure he appreciates them better than almost anyone else and would be the first to acknowledge them.

But compromises have to be made to create a useful langague and path dependency means that sometimes the sub-optimal long term choice is still the right choice to make right now.
I just want to note that while housing prices are probably normally distributed, "minimum wage" is a "arbitrary" value that cuts of the long tail (effectively increasing average wages).

As, per that definition, wages are now not normally distributed anymore it (statistically) does not even make sense to talk about average (i.e. mean) wages anymore.

More anecdotally: I recently looked up mean and median wages in Germany. And what I found is that the median netto income (per employer) does not really differ from the netto income per household. I guess that means that the average German household only has one person working (while the other is probably taking care of potential kids).

Then the original code is perfectly fine and does not need refactoring. You create the mocks you need with cleanup defers and you're done.

You could just make a function that creates all the mocks needed for all tests, but you don't like that. So the only option left is to specify which mocks you need for each test... which is exactly what the original code is doing.

You're running into a wall because you're trying to abstract code that's already maximally abstracted.
Because nuclear is effectively done for.

The dream was "power too cheap to meter". Didn't come true back then, and it turns out after you account for safety systems like a containment building and backup cooling, it's far more expensive than alternatives.

To make things worse, making nuclear remotely profitable relies on running it as close to 24/7 as possible. Given that renewables exist and produce cheaper power, nuclear only gets to offer anything when renewables aren't working, which makes it even more expensive.

Economically, it's extremely risky. Why risk billions on a plant that might profit 20 years down the line, when you could build solar or wind faster, and profit faster?

Politically, it's not great because construction times are very long, so any politician that starts building them probably won't be there to see the benefit, and may have their work stopped by a successor.

Practically, we can't build it fast enough. It's a big, complex, specialized tasks that few people do because there's not much market.
All the good mechanical bluetooth keyboards I know are almost as heavy as this console. Is there anything actually portable in this form factor?
Formally? Unambiguously, CCIR System M is the international formal designation for the US* format of the signal. It does not state what color format it uses - PAL-M (in Brazil) is such a frankenstein format that is not seen anywhere else - but domestically-speaking, NTSC (is confusingly) both the B&W and the backwards-compatible color format, and if someone didn't bother to change the name to ATSC (A standing for Advanced, not American), we could have NTSC Digital 3.0 instead. NTSC (National Television Systems Committee) is the committee which formulated these standards, they didn't bother to put a more proper name to their inventions like SCART's (the association, see below) SECAM and Telefunken's PAL have, or in the digital domain EBU's DVB and ARIB's ISDB.

(SCART is another one of these btw, it means Syndicat des Constructeurs d'Appareils Radiorécepteurs et Téléviseurs (Radio and Television Receiver Manufacturers' Association) and it was supposed to be called péritel (insert IBA ENG video discussing SCART) but the name stuck.)

When I was growing up, we where educated regularly on the horrifying atrocities committed by chaps like Stalin, Hitler, Mao and Pol Pot.
We where told how there was a strong desire after WW2 to keep power in check. To balance power so that no one state could become unstoppable. To try and prevent any one leader from becoming so powerful that they could no longer be challenged. Hitler was a famous fan of big tech, those IBM computers he used where massive.

The unchecked expansion of tech firms during the Obama years created the hypercentralised industry we call Big Tech. If a Stalin or a Hitler showed up today and seized all of this power, the civilian population would be powereless to defend themselves. No foreign power would be able to disrupt the holocaust this time. The mid 20th century doctrine of the balance of power aimed at preventing this by dispersing power, and ensuring that the big players are roughly balanced. But just like the MAD nuclear strategy, this had been abandoned, and the future is now a very uncertain place.
I believe it gets payed for by insurance in basically any other country.

I can only talk about germany: For type 1 diabetes insurance completely covers it. For type 2 it may get fully covered but it depends on some factors, but even then you don't pay the full price, only a part since the insurance will almost always at least partially cover it.

Their "What We Do" page has some more detail, but not a whole lot: https://openinsulin.org/what-we-do/

> To produce the protein needed for insulin, we need to grow microorganisms with a bioreactor and purify the protein from the culture with a protein purification system (FPLC). Proprietary examples of this equipment come at a very high initial cost and with high ongoing costs of support from the manufacturers. Our goal is to develop easy to manage, easy to repair, and affordable equipment to sustain local and community-built insulin production.
> Our FPLC design is in the early stages, and we are steadily developing mechanical and electrical designs to detect UV-C absorbance and manage the concentration of two buffers via peristaltic pumps and a mixing chamber. We plan to use Arduino microcontrollers as well as the Raspberry Pi, and the finished device will make use of the open-source Ender 3 3D Printer to facilitate automated fraction collection with G-CODE input. The bioreactor design makes use of quite a few commercial off-the-shelf parts and is ready for prototyping.
In a societal collapse scenario, you probably want to live in a country with decent defence ability and enough clout to throw its weight around in international diplomacy, even if quality of life is lower than some of the smaller, better located, better governed countries. Eg. Germany over Sweden.
A heart uses nowhere near 100W of power. That's about the overall power consumption of the entire human body at rest.
It's probably a horizon thing. Over millenia BAU would have been totally off, 50 or 100 years - not clear to me. Should be historically testable, i.e. mean and median time between larger changes. I suspect that in the last 300 years it accelerated a lot on the tech AND social side.
Steam input. If a game supports steam input, the developers can create a mapping for controllers that is automatically loaded for users using a controller. You're also free to modify these layouts in the comprehensive steam input UI provided. People can also share their mappings for a specific game which anyone can select in the community section for that game's steam input menu. Often times community mappings will be better than developer created mappings, and the community mappings have a rating system so you just search by highest rated or most downloads etc. The best part about steam input is that it makes enabling gyro support easy as, so long as the game supports simultaneous mouse and controller input at the same time (which Valve exclaims to developers in the steamworks documentation to make this possible).
