Who else is a company headquartered in the US that is willfully ignoring serious human rights concerns accountable to? This is exactly what government is for. And they certainly cared in 2007 when Yahoo was behaving similarly [0]. Hopefully

I hate to bicker, but, according to Google's own AI Principles [0], they have a self-imposed obligation to respond to serious human rights concerns. They promised not to pursue "technologies whose purpose contravenes widely accept

To be clear, this isn't about doing business in China. It is about responding to 14 human rights organizations having serious concerns [0] about proactive censorship and support for surveillance. And I agree that Google is far from a

I'm happy to see serious human rights concerns addressed in any and all forums.

Respecting Article 19 of the 1948 UN Universal Declaration of Human Rights [0] and concerns from 14 human rights organizations [1] is not America specific. It is about not secretly sacrificing basic freedoms in exchange for access to market

Hopefully he will testify about Project Dragonfly as well. Human rights concerns should not get lost in the noise of partisan politics. EDIT: Also, here is a slightly better stub article with an actual quote from Judiciary Chairman Bob Good

The letter [0] actually argued that "Dragonfly is part of a broad pattern of unaccountable decision making across the tech industry". The article seems to have recently been modified to link to it. [0] https://int.nyt.c

Thank you. I needed that.

I am genuinely frightened by how little respect a coalition statement from 14 human rights organizations is being given. Please at least read their arguments.

Consider the case where f is an elementary function of one variable and you know that its slope between any two points is at most k and at least -k. And suppose you want an upper bound on f(0) but you know the values of f(-2) and f(3). Then

The first page (no snark intended) shows that about 21% of the income goes to salaries, and 79% passes to charities. Regardless of what one's conclusions are on whether this is an acceptable overhead, it is an important consideration i

It's worth noting that the leader of the break in, William Davidon [1], was an Argonne researcher who invented the precursor to BFGS (though it took the community a long time to publish his quasi-Newton method). [1] https://

I wasn't a home buyer and am pretty sure I would have done this research if I had been. But, the point is that people that grew up here didn't have this as common knowledge; in hindsight, yes, but it's almost beyond the pale

I would recommend starting a code peer review circle with your fellow domain experts and never allowing yourself to push to your repo without someone reviewing.

lulu.com is a great place to cheaply print books and it only takes about a week. I am not a lawyer and have no idea about its legal applicability, but one just uploads a PDF.

One trick for breaking that is to get addicted to improving your craft. For me, it was originally starting an open source project, but there is something magical about a cup of coffee, a big stack of paper, and a math book that you have jus

As a counterpoint, it is worth noting that essentially no high-performance BLAS or LAPACK implementations (e.g., GotoBLAS/OpenBLAS, ATLAS, BLIS, etc.) are implemented in Fortran and instead tend to use a combination of C (in order to u

Many, many, very smart people have worked on exactly this problem and the result is a large, somewhat disjoint, family of techniques for forming/applying approximate inverses in subquadratic time for delicate families of matrices (e.g.

Duff (who was Davis's post-doc advisor IIRC) also deserves credit for MA57, which is used in MATLAB's sparse symmetric indefinite solvers [1]. And the giant BLAS and LAPACK crew (as well as the previous LINPACK authors) deserve so

Given that most academics have, almost by definition, previously prioritized their work environment over their salary, one shouldn't even assume that an academic receives an (immediate) multiple factor raise by making the transition.
