As much as I agree with the sentiments of BLM, this cannot be overstated.

Media conglomerates are amplifying the BLM "white/black divide" to distract from the fact that law enforcement bullies and assaults EVERY ONE OF US if the circumstances are right.
But that is the problem: we are claiming that we "know" things are absolutely true, but we are using methods that are known to be inadequate for that purpose.

Mathematicians are smart, but they are human. They make mistakes and miss others'. Math has increasingly become too complex to entrust mere human verification as being adequately trustworthy. Human verification has already been repeatedly demonstrated as inadequate.

We must choose between truth or easier-to-understand claims that are sometimes false because we depend on fragile human verification. I think we should choose truth.

Where we can get human understandability as well as truth, great! But formal verification should become the minimum over time, because truth should be the minimum.

We can't do that all at once right now. But knowing the goal is the first step.
Okay, time to have another shot at understanding Clifford Algebra!
But they also prevent other stores from being built. And they prevent sideloading. It's their store or nothing. They created a marketplace and ban other marketplaces. wtf?
> I've lost some gmail accounts because they will ask me for security questions when I log in with the correct password, and I don't remember them so my account gets locked, so they're gone forever.

Oddly for me it seemed like as time went by I had a better chance of recovering old gmail accounts with spurious remembered information, like the algorithm thinks the longer nobody's in it the more likely you're the owner trying to get in. This was ~10 years ago though.
Natural gas costs more than solar power under 50% utilization. As in the fuel it’s self costs more than solar power plants that waste half of all power produced at current prices. This means a vast over abundance of supply is part of any rational minimal cost strategy. Storage costs are so high it further makes solar tracking arrays cost effective for mitigation of the duck curve.

Also, hydro is a massive part of the energy mix going forward and excluding it gives meaningless results.

I've lived in China and the US and it doesn't even come close to the diversity of thought as the US. That said, they still crush it despite the lack of diversity of thought. With the US diversity of thought also comes the diversity of work ethic. China doesn't have that issue. A lot of the diversity of thought China has typically comes from expatriates that have returned home after meaningful experiences living abroad. This alone demonstrates that genetics is a terrible proxy for diversity of thought. What matters is cognitive diversity and diversity of experience.
There are a lot of things wrong with the monopolistic gate-keeping of the Apple/Google app stores, but it is funny that the thing triggering the whole debate is really just @dhh trying to get a better deal than the 30% shakedown.

5%,10%, 20%?

Converting silicon dioxide to elemental silicon is usually done by reacting with carbon, which produces carbon dioxide as a waste gas. However, in principle, the carbon dioxide could be captured and even recycled back into carbon to reuse in the initial reaction. I don’t think this is being done yet (at least not on a commercial scale), but there is no reason in principle why we couldn’t develop such a technology and combine it with nuclear/renewable power sources to reduce greenhouse gas emissions and fossil fuel consumption due to silicon refining to zero.
(Right, publicly)

I suppose developers are most likely to speak up when Apple has applied the rejection. And that is when you want a lifeline the most -- public shaming doesn't necessarily help your friendly HN-reading Apple employee to reach out and make a case.

The App store rules don't seem that vague -- just draconian. Sure, 30% of a paid app. IAP through a nice end-to-end Apple experience, where consumers don't have to enter any new information, are 30%? Make sense.

Can't offer IAP yourself? I can go either way, but to me this is the line where Apple is turning the screws. Boy do they turn them. Can't offer subscriptions outside the app. Can't link to other options for payment. Can't have a front end to a SaaS app that is primarily used on other platforms. Can't even mention the fact that Apple is taking a cut.

The app store rules do seem somewhat arbitrarily enforced. Ok, your 1.0 goes in but a critical bugfix? Now we shake you down.

If I were affected by this, especially for a subscription app I'd be contacting other affected parties and trying to educate the public on exactly why their subscriptions cost $14.28 instead of $9.99

Through Google SEO, of course, instead of inside the app, because Apple restricts what you say in the app about app store pricing.
> There's nothing preventing you from having an unrestricted device but having your improved experience.

Agreed. I, as a consumer, would like this option the best. If a free and open competitor to Apple made better devices and better software, I would jump ship immediately. I lament Apple's increasingly poor decisions, but have no better alternative currently, because competitors just aren't as good at what they do. The answer isn't to strong arm Apple into changing the way they do business on their own platform, the answer is to build better alternatives. (IMHO)

> I'm sure there are plenty of restrictions that would improve the overall experience for many people of many things that are still banned. Plenty of people would like all of a certain race banned from their apartment complex or town. I guess by your argument if they opt in to that experience because it's better for them it's should be no problem.

I know you gave this as an absurd gotcha, but yeah I have no problem with that. For the sake of argument:

- Town A wants to segregate, everyone in A would be happier with racial segregation.
- Country X does not want segregation, the people have spoken and decided that segregation is immoral.
- Town A should be free segregate to their hearts content, just not in Country A.

It's an upsetting thing to say but there's just too much risk dealing with them for projects with tight timelines/budgets.
There was a recent discussion on HN that branches into this idea about the importance of UX. I agree with you, with a twist.

What you want is that the happy path for security is zero hassle, but the unhappy paths should also drop dead with zero hassle.

This is the UX I really like for WebAuthn / U2F.

All the interactions on the happy path are very smooth. Need a second factor, tap, go. Almost frictionless. On my phone for example you tap the same fingerprint sensor that would ordinarily unlock the phone. Short of not having a second factor at all it couldn't be smoother.

But if this is actually a phishing site or you're a crook who doesn't have the hardware token, it just doesn't work. Still low friction in a sense, but low friction failure. There is no way forward, no override, no "I'm sure", nothing - it just won't work.
I for one am hoping to see a Zachtronics-like game where you get presented a chemical factory and then program all the relevant control logic.

Maybe part of the game could be determining where to add instrumentation of various kinds or making changes to the process. Extra fun is when the process behaviour depends on feedstock properties that aren't directly observable or environmental conditions.

Dont get me wrong, it is an amazing piece of tech for stabalising the grid and reducing the dependence on the gas peaker plants but it is a very long way from mass storage for want is a fairly small Aussie state. SA still regularly pulls a lot of power from the Victoria grid which is still dependent a lot on dirty brown coal.

Tweet thread seemed to imply Xcode 3.1.4 was being used. I think you needed Xcode 3.2 to target the first gen iPad (which is Snow Leopard or higher as you mentioned). While UTM wouldn’t probably work on it, I did get Bochs running on the first gen iPad and booted Windows 95 (albeit it took 45min to start and the iPad felt like a hot plate), so I wouldn’t say impossible, just very very unlikely.

Not just "people" too, but the tech-literate folks who generally lead the herd.

I remember within the past few years when I was talking to someone who seemed to be unfamiliar with the idea of storing all your really important papers in a safe deposit box. I'm not sure if that's the times have changed, or the particular person I was talking to, or that it never was that standard.
My assertion in more detail. First, there aren't big population-level differences amongst random partitions of the single human race. There are population-level differences amongst geographic partitions, and humans are known to not travel especially far from where they are born, so that we might suspect genetic drift is happening; humans tend to not spread genes very far geographically. Indeed, there are countless examples of genetic drift in humans.

Second, those drift differences are largely cosmetic, and cosmetic on average. Both properties follow from differences being Gaussian distributed with respect to fitness; the typical drifted gene is neither especially fit nor especially unfit.

Third, as gene pools grow, the ability to control for fitness on a per-gene basis shrinks exponentially, so that the behavior of the pool is like a random permutation. To see this, imagine a picky procreator choosing from a list of suitors by genetic partition; at each stage, they will reject some suitors who have the wrong allele. The pool randomly combines each pair of alleles (because it is deep enough to hold every viable combination), so each rejection removes roughly the same proportion of suitors every time. Thus, a linear list of picked alleles requires an exponentially-large list of suitors to choose from!

Aside: This third fact is why breeding dogs gives us pugs with their poor breathing and also why breeding tends to give us lots of hip dysplasia across different breeds. We can only positively select for a relatively small handful of traits and alleles, and each selection allows thousands of selfish genes to join the entourage, giving us patterns of unwanted gene expression.

None of these facts preclude services like 23andMe; we can certainly write down lists of clustered alleles which correspond to drifted genes, and use that information to correlate people with the geographic history of their ancestors, on a probabilistic basis. (Remember, large gene pools are randomly permuted, so these services must be probabilistic.)

None of these facts preclude some genes from being selected for fitness, either. Let's examine sickle-cell anemia more closely. Sometimes a mutation can improve an allele's fitness when one copy of the gene is present, but two copies results in a poor allele. Sickle cell is a very good example of this. Having one copy gives the "sickle cell trait", which resists malaria. It has a bunch of other minor health effects, positive and negative, but resisting malaria is sufficient to allow the gene variant to stay in the gene pool.

What I'm saying is that, just because some people have sickle-cell anemia, that doesn't therefore change the fact that people are all of the same species. If folks want to talk about which individual genes they have, then they should do that, and not talk about race, because genes only stick together in geographic clusters probabilistically, due to drift.
Companies needed senior officials to be physically seated at their desks just so they could apply hanko to company documents, without which entire businesses would have ground to a halt.

A few things stick out to me:

* This study assumes that we can ramp up purchases of solar and wind generation to match this graph: https://imgur.com/lMU252r while costs continue to decrease. That's not how markets work. Rapidly buy solar panels and the cost of solar panels go up. Put solar panels in all the places where it's easy to install and now you have to pay extra to put them in places where it's not so convenient.

* This study thinks we can achieve this with only ~200 MWh of storage. This is an optimistic projection. To put this in perspective, daily US energy use is 11.5TWh. We're giving solar and wind generation only ~15% allowed variability before we're dipping into gas. Yeah, it does say that it's only 90% clean electricity, but even reaching this figure is optimistic.

> it's not one that's fixable except by users changing their preferences.

By definition market failures can't be fixed by market dynamics. That is why state does tons of interventions/regulations to make it work.

> That's called free market competition, not monopoly.

No. Vertical integration means there is no free market at the integration point to begin with, which integration of a software application store with a physical phone is. We are talking about a $50bil/year market that is not free.

Nuclear energy, so far, is the only proven way of producing more than 3/4 of a nation's electricity from carbon free sources other than geographically limited options like hydroelectricity. It's a proven technology that has served as France's main electricity source for close to 4 decades. As compared to plans to turn our power grid into a Rube Goldberg machine and dealing with power outages when wind and solar output don't conform to projections, it's not hard to see why people favor nuclear.

By default, it’s difficult to follow the rule of writing simple, readable code. We want to show how smart we are, how we can write something that others cannot do. It is in our nature.

Over time, when we gain experience and self-confidence, we begin to appreciate the simple and understandable code.

Another, more difficult, way is to consciously apply the “avoid smart code” rule and follow it every time you solve a problem with code

Linear type systems often enforce that requirement by saying both branches need to use exactly the same linear values (or consume the same resources). So your example would be rejected by the type system. For example, the following function would not type check in a linearly-typed language because then branch is using x while else branch is not using x.

-- Using Haskell-like syntax, '-o' is linear arrow, i.e. lollipop
foo : Int -o Int -o Int
foo x y = if y < 0 then x else 0

> For example, my credit union has a $0 liability guarantee for fraud on my debit card

Even with that, I'd still prefer a credit card. If there's fraud on my CC, I haven't lost anything. If there's fraud on my debit card, there will be a period of time where that money will be gone before the bank investigates and decides to give it back to me. Even if they are 100% reliable at giving it back to me, the money is still inaccessible for some non-zero period of time.
