In a bold and unprecedented measure, Los Angeles county has banned crime.

What business does Facebook have helping prisons censor speech? This is atrocious.

"Facebook has been suspending the accounts of inmates for at least four years at the behest of prison officials. Facebook even had an easy and confidential 'Inmate Takedown' form corrections officers could fill out to make the profiles disappear. ... We could file public records requests in all 50 states to learn more, but since Facebook’s system allowed prisons to file these requests without creating a paper trail, only Facebook knows how many requests it has complied with nationwide. ... In preparing 2015’s Who Has Your Back? report we gave Facebook multiple opportunities to come clean about government requests to suppress content."
If you click around Facebook’s “Government Request Report,” you’ll notice that, for many countries, Facebook enumerates the number of “content restrictions” the company has fulfilled. This is a sanitized term for censorship.

Yeah Facebook doesn't even pretend to provide anyone a service they like, it's just 100% understood that it's the network effect or else people would probably prefer some other site. So at that point it's not really any exchange of value except, how much can they bleed people before they squeal. A lot, apparently.

Abstract: In response to Jaffe and Quinn [math.HO/9307227], the author discusses forms of progress in mathematics that are not captured by formal proofs of theorems, especially in his own work in the theory of foliations and geometrization of 3-manifolds and dynamical systems.

A puzzle related to current events:

w is an invertible map from a subset of M to a subset of F.

w' is a permutation defined on a subset W of (M U F), such that for all p in W, w'(p) != p, and such that w' is its own inverse.

What are w and w'?

And by extension, what would w'' be, if w'' is an equivalence relationship on (M U F)?

Equivalence relation is polygamous spouse. The rest are self-evident. :)

Perspective.

40 years is a short time in history, but a long time for a person to wait.

Also this from Andrew Sullivan, once one of the lone voices in support of gay marriage: http://dish.andrewsullivan.com/2015/06/26/it-is-accomplished/
Given how embedded, pervasive and recent anti-gay sentiment has been in the fabric of American life, witnessing the arrival of full-scale legal equality is surreal.

I didn't even know Facebook had an "inmate account takedown program". That's ... f'd.
Since at least 2011, U.S. prisons have had a special arrangement with Facebook. Prison officials would send links to profiles belonging to inmates that they wanted Facebook to take down. Facebook would then suspend the profiles, often no questions asked, even when it wasn’t clear if any law or Facebook policy was being violated.

Summary: SSL as commonly implemented today is largely broken, and the NSA probably has an exploit.

Not The Onion.
An overachieving bigot in Nebraska reached an impressive new level of intolerance this week, filing a lawsuit against “Homosexuals”—as in all of them, everywhere—in a U.S. District Court on Friday, NBC News reports.

Crew Dragon had its first "flight" this morning -- a spectacular (and successful) test of the launch abort mechanism, should anything go wrong on the launch pad or during the flight to orbit.
