Evolutionary explanation? There's a whole missing level of analysis here. Evolution doesn't operate directly on behaviors. It operates on physiology.
Of note, evolution is not equal to natural selection. "random mutations" are causes of evolution, drift (random) or selection (fitness benefit) are both mechanisms by which mutation can manifest in a population.
- The PC is in decline (bad for intel)

- Intel lost the mobile platform

- Apple is moving to ARM, PC laptops to follow soon.

- AMD is eating intel lunch in the high performance x86

- Servers are starting to move to ARM

Last piece of the puzzle
- Intel is not doing great at the fab level.

It doesn’t look good for Intel, they need to do a radical transformation fast.

Correction: VOTERS are suffering because their choices are no longer meaningful.

(Two party system is broken and neither does a good job of serving the interests of their voters. "Vote harder" isn't practically effective and displaces blame to the victims.

> A disturbing feature that I don't see a way out is that in git there are "standard" and "history-rewriting" operations, and there is a clear distinction between the two. To what would that correspond in terms of pure file operations? Something about changing the default permissions?

> "history-rewriting" operations

Git is a Merkle hash tree. You can never rewrite history. Instead, what you think of as "history-rewriting" operations is just "non-fast-forward" changes to branches. Branches are really just named pointers -- {branch_name, commit_hash}. A change to branch from {$name, $commit0} to {$name, $commit1} is fast-forward IFF $commit0 appears in the linear history of $commit1. A non-fast-forward change to a branch is what you call a "history-rewriting" operation.

There's nothing wrong with "history-rewriting" -- I do it all the time. It's only ever bad when you do a non-fast-forward push to a branch that others track, and even then it's not the end of the world because usually those others can recover easily enough with `git rebase --onto`. Rewriting the history of a public branch is a problem, yes, because you want the history to be stable and reliable so you can use it to figure out problems, understand the history of the project, etc, and because making others have to `git rebase --onto` is impolite.

It's essential to understand that the only destructive operations in git are a) non-fast-forward branch changes, b) tag changes, c) gc/prune operations when you're like me and you're used to working in detached-HEAD mode.

If you're stuck on "Git has history rewriting, and that's bad!", then you've misunderstood everything about modern version control systems. You can -and I have- do the same sorts of destructive operations in version control systems going back to the early 90s (e.g., Teamware, CVS), to say nothing of newer ones like Mercurial, Fossil, and, of course, Git.

Inb4 "But Git encourages history rewriting" -- that is neither true nor a good argument.

> In 1970 countries agreed to give at least 0.7% of GNI [0] and the US has been giving severely less than that for decades

The US and nearly everybody else. The biggest exceptions most recently? Sweden, Luxembourg, Norway. Gee, I just can't figure out why the US doesn't match Norway (or other tiny hyper affluent European nations) on such a matter. The only real exceptional outcomes in that list are Britain and Germany, and France to a lesser degree - outside of that the entire world is largely failing badly at that supposed test.

Meanwhile during that time the US supplied nearly half the world's food aid, while only representing 4%-5% of its population. A tradition of food aid going back more than a century now.

For example:

"The U.S. contributed $3.4 billion to WFP [UN World Food Program] in 2019, which was 42% of all contributions last year." - from the UN WFP homepage. And that's just to one entity.

Globally at present the US is supplying around 40% of the world's food aid all by itself (the number used to be slightly higher in the past and I think the US should do more, however that's still astounding coming from one nation).

You know what the US should do? It should pull its military entirely out of Europe and Asia, and let Russia and China run wild (they'd promptly conquer and pillage like it was the 1930s all over again). North Korea would be in South Korea before the final US troops were out of Asia; South Korea would cease to exist as we know it today within a decade. Then we should cut that related defense spending, and redirect that former defense expenditure to meeting that 0.7% GNI target (and helping the people ravaged by the inevitable large wars, which is how we used to approach the problem circa the WW1 & WW2 eras).
Totally yes. The mechanistic illustrations of matrix multiplication, including the OP, are easy enough but don't help me with motivation or intuition.

I always start with Ax, which is just a linear combination of the columns, like the first figure here https://eli.thegreenplace.net/2015/visualizing-matrix-multip...

For those who want to make their own cheat sheet:

Matrix $\times$ vector is linear combination of the columns:

\begin{align}

Ax &= \begin{pmatrix}

a_{1,1} & a_{1,2}\\

a_{2,1} & a_{2,2}\\

a_{3,1} & a_{3,2}

\end{pmatrix}

\begin{pmatrix}

x_1\\x_2

\end{pmatrix}\\

&= x_1\begin{pmatrix}

a_{1,1}\\

a_{2,1}\\

a_{3,1}\\

\end{pmatrix}

+

x_2\begin{pmatrix}

a_{1,2}\\

a_{2,2}\\

a_{3,2}\\

\end{pmatrix}

\end{align}

Intuitively, this example maps a point in $\mathbb{R}^2$ to $\mathbb{R}^3$

Another way to see $Ax$: Columns of $A$ form a basis, and $x$ is a coordinate vector in that basis.

I'll take the even more aggressive tack than the other people who have replied to you: it actually is still a social safety net. Even people who (supposedly) bilk social safety programs have dependents, and those dependents do not deserve privation because you disapprove of their guardian's behavior.

Have a little perspective and focus your ire on our ridiculous military budget (which is also a welfare program, mind you) instead.
I agree, I'm just pointing out that when you have some abstraction X you almost always want to also provide its categorical dual ~X, or you end up having to write awkward encodings to simulate it.

Databases provide product types, and the dual of product types are sum types. As you point out, you can encode this in various ways, but it's not natural and very error-prone.
Correct. I'm very familiar with RL, but I didn't see how referring to RL literature fit in to my particular argument (and I'm not intimately familiar with that literature). That said, I'd suspect there are fruitful connections to make there, especially considering that this model completely glosses over learning, which is a pretty crucial element...

The K&A paper does mention the connection with RL: "Here, we consider the function of the circuit from the point of view of navigation, a connection anticipated by early work on TD learning (Montague et al, 1995)" (specifically, Montague et al found this connection when building a model of bee foraging).
That's incredibly annoying!
Sure, but why is a test needed for that? Why not test for any of the other sicknesses then, and not just covid 19?

It all seems similar to security theater after 9/11. A lot of effort and expense for little gain so somebody can say they did something.
What definition of hard are you using? It's an industrial strength tool used almost exclusively by professionals and expert-level amateurs. It's definitely hard, the same way knowing what to do with a welding machine is hard.

On the other hand, even among the professionals it has a reputation for being tricky and frustrating. Which is not the norm for most critical daily-use tools in this or any professional. So I'd also consider it hard in that sense.

> helps us get a handle on asymptomatic cases

This won't help us get a handle on asymptomatic cases - to do that, we'd have to be able to test everyone on a frequent and consistent basis.

This program doesn't even cover one test for everyone in my house, let alone weekly or more frequent testing. And aside from this, I have to spend hours looking for any available rapid tests to buy around here, and if/when I have some, I can't afford to use them on randomized or even weekly testing.
That can sometimes be a solution... Just keep in mind, you are manually writing a join algorithm every time you need to do that, and sometimes it will be the right one for the task, other times not so much. The query planner will adapt your join type for you instead, if you can trust it.

As the shape of your data changes over time, your hard coded algorithm choice is not guaranteed to be the best one.

Depends if materialization helps.

As a silly example, if the CTE materializes 1/100th of a table via table scan, scanning 1/100th of a table N times may be faster than scanning the entire table N times.
> a reason for the mass testing

Covid is much more dangerous for the elderly than the young, even vaccinated. The young are so safe that there have been ~250 total covid deaths in the US age 0-4.

Also, there is growing evidence that the lateral flow tests correlate well with being infectious.

Testing reasons:

For lots of staff (medical, school, factories), to avoid unnecessary prophylactic isolations, particularly for people whose work cannot be done remotely. And for the same group of people, testing daily (were we in a competent country with the test manufacturing to support) could significantly reduce community spread. Daily tests are infeasible to do with pcr if for no other reason than the reporting lag.

For visiting high risk people: reasonably reliable, fast indicator of whether you have covid in order to make near realtime decisions about activities to engage in. Like masks, this will reduce community spread.
This is what I mean by setting vengeance up vs. "the bare mininal extent required to protect others".

I agree that there are still people who needs to be locked up, including under possibly brutal sentencing terms. E.g. Anders Behring Breivik who carried out the 2011 terrorist attacks in Norway is up on a parole hearing today - if he gets out (it'd take a miracle) it doesn't matter if it's free will (in any sense of the term) or purely deterministic processes that leads him to act if he is still probabilistically likely to carry out another attack - it's still more important to keep the public safe from him than to worry about whether or not he had a genuine choice.

To the extent there's a measurable effect of seeing the punishment of others, that too might be a justification, though I find that dicier. But if that is done based on a cold calculation of how it affects offending rates that to me is still very different from vengeance.

So to be clear I'm not arguing it removes the justifications for punishments, and I agree with your mention of seeing it as a game theoretic situation - even really harsh punishments might be the best choice in some circumstances. But it removes "they chose this themselves" or "they deserve it" as a justification (the feeling is still valid; acting on it becomes cruel), and that makes for a very different legal system. It also shifts a focus towards considering that if it's not about vengeance, then you should look at how to actually optimise the balance between the public good and treating the prisoners as humanely as you can without reducing the public benefit of the punishment too much.

Norway is far from achieving that, but if you look at e.g. Bastøy fengsel [1] ([2] has links to assorted longer articles), you can get one idea of what de-emphasising vengeance and taking rehabilitation and trying to address reoffending rates might start to look like (though Norway has by no means solved that, Bastøy also certainly haven't made it worse, but it also is not the norm in Norway either - yet anyway). For some people, it might well be that harsher prisons works better, or are necessary (I doubt Breivik will ever get the chance to serve his time somewhere like Bastøy for example). (Bastøy is the - so far - culmination of a process of reform that started in the 1960's, at a point where Norwegian prisons were quite brutal and the brutality of it eventually triggered a strong counter-reaction.)

For others even less prison (Norway as it is have sentences that would look comically short for e.g. Americans or British people). But evaluating it as a "game theoretic situation" as you say would in any case very likely lead to very major change to how the legal system would work most places in the world (including Norway)

One case that you know of. Unless your entire friend circle has all been getting weekly tests since February 2020 it's likely that some have had asymptomatic infections. The CDC estimated that only about a quarter of infections were officially counted as "cases".

Most independents have strong political beliefs, they just don't necessarily align neatly with the parties. Many are single issue voters or subscribe to non-centrist ideologies. The contested middle is mostly a myth. Of course there are genuinely apathetic people out there, but typically they are staying home on election day. If they do feel a civic duty to vote, they can vote third party. What shifts is the passion people have for one party or another. If you normally vote democrat but don't consider yourself a democrat, odds are you are dissatisfied in some way with the democratic platform or candidate; you're not going to vote for a republican instead, but maybe you're not going to stand in line at the polling booth for the democrat either.

At least for the past several elections, victory has come with energizing the base. In 2016, for example, there wasn't some noticeable shift to the right, Clinton only got 62000 fewer votes than Obama won with in 2012, but Trump got 2 million more votes than Romney did in 2012, because people who stayed home in 2012 came out in support of him in 2016. Conversely in 2020, Trump received 11 million more votes than he did in 2016, but Biden received over 15 million more votes than Clinton. Between the changes in overall election turnout and variance in third party voting, there's been no net shifting of votes from one side to the other in between any presidential election this century. Now it's a little more complicated than just getting people to come out, getting high turnout in the right areas is critical, so that fudges things a little bit. For example in 2016 Clinton had very comparable overall numbers to Obama in 2012, but she had dramatically less support in midwestern urban centers and stronger support in the south, which is pretty useless in the electoral college. But again, its not that people in the midwestern cities were voting for trump, they were staying home while suburban midwestern blue collar workers who traditionally didn't vote turned out.

> people pushing these ideas aren't "stupid"

GGGP was not calling these individuals stupid, rather, their interpretations of the law. And while they're not argued by stupid people, you would certainly have to be stupid to believe such arguments, e.g. the one at issue in this case. I don't think Axel Springer's lawyers are stupid. I think they're malicious. I think their argument is stupid and one should have to be stupid to believe it.

> in a more familiar context, if you are working with someone and they are making bad design decisions, calling them names isn't likely to be well received, but providing a better design is helpful.

I work with reasonable people. Entities like Axel Springer are not reasonable because they have a vested financial stake in the matter. Reason and debate won't change the money at stake for them.
Chinese surveillance and censorship tool required of Olympians
The Globe and Mail reports that the Citizen Lab at the University of Toronto has analyzed the My2022 app that Olympians are required to install on their device and found that encryption protecting users' audio and file transfers can be sidestepped and that keywords such as Tiananmen can easily be censored. These flaws violate Google and Apple's App store guidelines as well as China's laws and standards.

I believe her talk was from late 2017, so 7nm would have been expensive.

At the same time, AFAIK Intel was doing quite well at 14nm finfet even then (likely better than any other foundry?), but that production capacity was not available to ARM, so I guess it didn't count.
