I don't understand why major arm contracts suddenly went from having obvious geopolitical implications (e.g. Turkey S-400 procurement) to being "mere contracts".

Well, except for people born as women who take testosterone, then.

Testosterone is a banned substance because it is a performance-enhancing drug.

jean_tta··on What is traceability and why does WhatsApp oppose it?
When?

In 2012, when the top two candidates have ~50% of the votes & four candidates total are above 10%?

In 2007, when the top two candidates have ~50% of the votes & four candidates total are above 10% (note: note the same parties)?

In 2002, when the top two candidates have ~35% of the votes and the loss of the leading left wing candidate was blamed on too many different left wing parties fielding candidates and getting votes?

In 2002, when the top two candidates have ~45% of the votes & four candidates total are above 10%?

Same thing for 1995, 1988, 1981.

In the last US presidential election, the top two candidates got a combined 98.17% of votes. The next candidate got 1.18%. This is a completely different situation.

jean_tta··on The Missing Semester of CS Education
> I agree with your basic point though some students do freeze up with even relatively easy math.

That's the opposite of my point, really.

> And liberal arts courses are not necessarily easy today--especially at a good school. You'll be doing lots of reading and writing.

My point was about the "within university" variance of student levels rather than the "between university" variance. I have no doubt that a liberal arts programs in a good university is more selective than the CS program at a particularly non selective university. However, within any given college, I'd be surprised if the liberal arts program manage to get the above average students and the CS/Math/... programs get the below average students.

jean_tta··on The Missing Semester of CS Education
More generally some departments, including CS but not only, get away with picking above average students in a given college and letting other departments get the below average students, through things like "weed out courses" or not teaching actually 101 courses but "assuming a lot of background familiarity with computers", to quote what you say.

Difficulty of any given program at the undergraduate level is completely dependent on university policy. Maybe at the research level, you truly need to be more intelligent / harder working / whatever to succeed in math than in art history, but at the college level, you could do for instance:

- cram all that is taught in current undergrad, MA, and PhD (including the thesis) for art history in 4 years

- let CS students graduate if they can write any working program in any language of their choice

Tada! Art history is now the hardest degree in the college where only the best students aren't weeded out out; and CS is the easiest degree there is.

My point being that CS departments assuming prior levels of CS unlike other departments is merely an instance of a larger pattern.

jean_tta··on A Somewhat Comprehensive History of U.S. Senators Who Have Died in Duels
I think this would be mostly solved by reporting the life expectancy at some other age than birth - e.g. the life expectancy at 20, thereby cutting out the effects of child mortality - or reporting the median age of death.
jean_tta··on Crazy New Ideas
A very smart man, PG himself, once said [0]:

> I actually worry a lot that as I get "popular" I'll be able to get away with saying stupider stuff than I would have dared say before.

PG started writing essays about what he knows well (programming, start ups), then about things he knows a bit (painting) and then stuff like this, or his essays on economic policy. In any case, he predicted his own future quite well.

jean_tta··on How Big Tech got so big: hundreds of acquisitions
Note that I was not trying to make a statement on whether capitalism is great or which variety of capitalism is best. Rather I pointed out that the word "capitalism" is not a synonym for "free markets", both when used by laymen and by academics.
jean_tta··on How Big Tech got so big: hundreds of acquisitions
Your definition seems closer to ordoliberalism [0].

If competition and free markets are a necessary components of capitalism, then you would conclude - for instance - that the US stopped being a capitalistic country in the late XIXth century with so many prominent trusts. Or perhaps it never was capitalistic before WWII, since policy makers did not nurture competition but rather attempted to shield local industries from foreign competitions.

[0] Wikipedia definition: Ordoliberalism is the German variant of economic liberalism that emphasizes the need for the state to ensure that the free market produces results close to its theoretical potential

jean_tta··on Apple’s M1 Positioning Mocks the Entire x86 Business Model
I am not arguing that the product naming is perfect, only that is not completely absurd as others claimed.

Comparing the performance of laptop and desktop is a niche case. Most people know whether they want a laptop or a desktop and then choose among those categories.

jean_tta··on Apple’s M1 Positioning Mocks the Entire x86 Business Model
Most people have no need to compare CPUs between mobile/non mobile or generation. They just need to know if the laptop they're looking at has the high end / middle end / low end CPU. You'd be comparing a new laptop with latest(-ish) CPUs.

The i3/i5/i7 makes it plain & simple to know that.

You don't need to figure out what the "middle end" CPU is called this year. It's the i5, problem solved.

jean_tta··on Princeton admits record-low 3.98% of applicants
% of applicants admitted is not super informative.

Two more interesting metrics would be:

* how many applicants admitted actually enroll (and not go to some other college)

* related, bu what is the "rank" of the last admitted applicant: how far do they need to reach to fill their spots?

jean_tta··on Dear Zuckerberg, We're writing to urge you to cancel Instagram for children [pdf]
With this reasoning you would never forbid e.g. hard drugs for kids, or child labor. Kids will always bad things to do, after all.
jean_tta··on Princeton admits record-low 3.98% of applicants
More broadly most applicants apply to several schools. If there are as many spots as applicants and each applicants apply to k schools, you could go as low as 1/k average admittance percentage (rates will be higher when colleges accept applicants that do not come: you could have 100% rate after all). With k = 12, you're at about a 8% lower bound for the average college.

For elite colleges that will attract more applications and will have fewer admitted-but-does-not-come applicants, 4% is not that low.

If the marginal cost of an extra application is lowering (say, because we went from typewriting & mailing everything to copy-pasting & online applications), the number of applications per applicant will go up and thus the admission rate will go down.

jean_tta··on EU Commission to end AstraZeneca and J&J vaccine contracts at expiry
> It's what happens when you stay at home too much and don't get enough exercise and have a poor diet.

Surely this means that "long covid" is not caused by the coronavirus infection itself, but by staying at home too much and a poor diet and not enough exercise. Is that not what this meant?

jean_tta··on EU Commission to end AstraZeneca and J&J vaccine contracts at expiry
I apologize for not being American and the press in my country costing money. I'll try to do better next time.

I note that your link astablishes that long covid is the thing, which the parent comment denies.

jean_tta··on EU Commission to end AstraZeneca and J&J vaccine contracts at expiry
It is my understanding that many doctors have found "long covid" to 1. be a thing and 2. have specific, unexpected symptoms. Now it is possible that they are all wrong, but could you perhaps give a few arguments why you are right and all those doctors are wrong?

jean_tta··on The Unlikely Rise of French Tacos
Which is quite ironic, because to locals the Champs Élysées is known to be a hang-out place for banlieusards, a place where companies have flashy flagship stores, and clueless tourists who do not expect either of those things. If there is a place to have O'Tacos restaurants in Paris, the Champs are far from the worst place.
jean_tta··on The Unlikely Rise of French Tacos
French tacos are only "tacos" in their name; the two foodstuff have basically nothing in common.
jean_tta··on China is betting that the West is in irreversible decline
I mean he was right (in that there was a decline of the West, or Europe in particular - I am not familiar with the content of his book beyond that). The West went from conquering & dominating almost every place of the planet despite being but a small minority of its population to losing the vast majority of their conquests. The tech difference between say Paris, 1918 & Shenzhen, 1918 was much higher than today - in fact I would say Shenzhen is ahead.
jean_tta··on China is betting that the West is in irreversible decline
> This is obviously mainly due to the boom in developed world esp China

Europe (and the "West" aka where Europe sent its surplus citizens) went through its fertility transition [0] earlier than the rest of the world. Hence it increased its relative size as it experienced a high fertility / low death period, and decreased its relative size after it went to a low fertility / low death while part of the rest of the world went into their high fertility / low death phase.

So we can probably expect currently high population growth to transition to the low fertility / low death endgame. China is already well past it.

As far as I know, no country went back to a high fertility / low death scenario, though countries stabilized at various level of low fertility.

Most Western countries have institutions that rely on population growth (high debt that would lead to enormous debt per capita if the number of people decreases, unmaintained infrastructure, pay-as-you-go pensions...). So they will either have to fix their fertility rate in a dramatic way, massively reform many of the core institutions of society, or have high immigration & handle it well.
