What American's die from vs What US Media reports on...
My baby cousin called me in tears because all her accounts have been compromised. We went over possible infection vectors (the “try my game” DM scam etc) and nothing stood out. But then she wondered if they’d gotten a foothold through the Canvas ransom somehow.
Has anyone else heard of students getting their personal accounts popped very recently in a way that might be tied to the Canvas incident?
Recently, Sébastien Labbé and Peter Selinger posted a preprint (https://arxiv.org/pdf/2604.20964) that describes a sophisticated construction for the hat tiling, based on what's called a Markov partition (see the thread by @pieter at https://mathstodon.xyz/@pieter/116484517078239617 for more details).
One nice side effect of their construction is that it provides a means of rendering the hat tiling on the GPU using a fragment shader. That's cool, because it requires a constant amount of work per pixel, regardless of how many tiles you're drawing, and you can pan around forever without ever worrying about running out of information about the positions of tiles (as you would with a drawing algorithm based on substitution).
I have a slightly glitchy prototype written up in Shadertoy. I'll make the code available, but I want to clean it up first.
New, from me: Canvas Breach Disrupts Schools and Colleges Nationwide
"An ongoing data extortion attack targeting the widely-used education technology platform Canvas disrupted classes and coursework at school districts and universities across the United States today, after a cybercrime group defaced the service’s login page with a ransom demand that threatened to leak data from 275 million students and faculty across nearly 9,000 educational institutions."
"Canvas parent firm Instructure responded to today's defacement attacks by disabling the platform, which is used by thousands of schools, universities and businesses to manage coursework and assignments, and to communicate with students."
