contiguous_usa: Contiguous states (USA)
A network of contiguous states in the USA, in which each state is a node and two nodes are connected if they share a land-based geographic border. The dataset includes the lower 48 states, and the District of Columbia.

NFL restricts access to contact info after Shedeur Sanders 2025 draft prank call https://www.nytimes.com/athletic/7213662/2026/04/20/nfl-draft-contact-distribution-shedeur-sanders-prank-call/
PSA: Newer contactless cards which can be disabled, just decline the transaction - they still scan; so with a wallet with both a disabled-contactless and an enabled-contactless card they can still scan the wrong one, unlike the old cards that when the bank gave you one without contactless really didn't have it.
Now I have to call TfGM and fix my tram fair screwup; and get the hacksaw out.
Evaluating #AGENTS.md: Are Repository-Level Context Files Helpful for Coding Agents?

"The most recent orbital computations make it increasingly likely that the object [the new #Kreutz comet MAPS] is a fragment of one of the comets observed by Ammianus Marcellinus in AD 363, thereby strengthening evidence in support of the contact-binary hypothesis of the Kreutz system," writes Zdenek Sekanina in https://arxiv.org/abs/2602.17626: "In this context, the comet is the only second-generation fragment of Aristotle's comet that we are aware of to appear after the 12th century. It does not look like a major fragment, but rather like an outlying fragment of a much larger sungrazer."
sp_high_school_new: High school dynamic contacts (2011-2012)
These datasets contain the temporal network of contacts between students in a high school in Marseilles, France. The first dataset gives the contacts of the students of three classes during 4 days in Dec. 2011, and the second corresponds to the contacts of the students of 5 classes during 7 days (from a Monday to the Tuesday of the following week) in Nov. 2012.
This network has 180 nodes and 45047 edges.
