email_enron: Email network (Enron corpus)
The Enron email corpus, containing all the email communication from the Enron corporation, which was made public as a result of legal action. Nodes are email addresses and node i links to node j if i sent at least one email to address j. Non-Enron email addresses are also present, but only their links to/from Enron addresses are observed.

"The fundamental problem is this: that most of the means of communication are owned or influenced by the very rich. If democracy is the problem capital is always trying to solve, propaganda is part of the solution. Like the kings and empire-builders of the past, they use their platforms to project the claims that suit them and suppress the claims that don’t. This means boosting right and far-right movements, which defend wealth and power..." -- George Monbiot.

This is a really good question from @…. The first thing I keep telling everyone in other cities who wonders how they can help, what they can do:
Get organized NOW. Meet your neighbors NOW. Get your neighbors set up with secure messaging NOW. Form multiple hyper-local neighborhood social groups NOW. Organize a block picnic or community craft night or repair workshop or whatever NOW. Get contact info for the human beings who physically show up for neighborhood events NOW.
Form all those local connections ASAP, so that they’re there when you need them. The hardest lines of communication to establish will be the ones with the people closest to you. If you get local lines open in advance, you’ll be in a far, far better place.

The Communication Complexity of Combinatorial Auctions with Additional Succinct Bidders
Frederick V. Qiu, S. Matthew Weinberg, Qianfan Zhang
https://arxiv.org/abs/2512.06585 https://arxiv.org/pdf/2512.06585 https://arxiv.org/html/2512.06585
arXiv:2512.06585v1 Announce Type: new
Abstract: We study the communication complexity of welfare maximization in combinatorial auctions with bidders from either a standard valuation class (which require exponential communication to explicitly state, such as subadditive or XOS), or arbitrary succinct valuations (which can be fully described in polynomial communication, such as single-minded). Although succinct valuations can be efficiently communicated, we show that additional succinct bidders have a nontrivial impact on communication complexity of classical combinatorial auctions. Specifically, let $n$ be the number of subadditive/XOS bidders. We show that for SA $\cup$ SC (the union of subadditive and succinct valuations): (1) There is a polynomial communication $3$-approximation algorithm; (2) As $n \to \infty$, there is a matching $3$-hardness of approximation, which (a) is larger than the optimal approximation ratio of $2$ for SA, and (b) holds even for SA $\cup$ SM (the union of subadditive and single-minded valuations); and (3) For all $n \geq 3$, there is a constant separation between the optimal approximation ratios for SA $\cup$ SM and SA (and therefore between SA $\cup$ SC and SA as well). Similarly, we show that for XOS $\cup$ SC: (1) There is a polynomial communication $2$-approximation algorithm; (2) As $n \to \infty$, there is a matching $2$-hardness of approximation, which (a) is larger than the optimal approximation ratio of $e/(e-1)$ for XOS, and (b) holds even for XOS $\cup$ SM; and (3) For all $n \geq 2$, there is a constant separation between the optimal approximation ratios for XOS $\cup$ SM and XOS (and therefore between XOS $\cup$ SC and XOS as well).

As we're reminding him of the challenge rules (stop when asked = 1 point), kid gets a twinkle in his eye and then screams briefly and looks at us.
Instant new rule: you don't get points for stopping activities that you started just to get points.
