@jedbrown Postprocessing for source obfuscation would be equally embarrassing, not to mention upsetting open source devs. Same rules as those I use in my courses: copy-paste all you like; just don't omit the source, pay attention to the license, and (for students) show understanding of the code by explaining it to a TA. The AI hype is in need of a snap to reality, and this lawsuit may very well be it.

New expectations on DORA signatories from now on 👇

"1) to make a public statement explaining their commitment to DORA;
2) research-performing organizations to ensure their implementation of DORA is informed by ongoing dialogue with staff and students who are involved in research and research-enabling activities.

The policy also states the action that DORA will take should credible reports be received of a signatory organization not living up to these expectations."

The Declaration on Research Assessment (DORA) recognizes the need to improve the ways in which the outputs of scholarly research are evaluated.

I'm a week late 🎃 but do any #CFD folks want to see a ghost?

One versatile technique for compressible flow is to implement "characteristic" boundary conditions by using a #RiemannSolver with a freestream solution outside. This nice paper discusses the technique and reports that HLL works as well as the more accurate solvers. But HLL doesn't represent the contact wave and fun things happen after the cold bubble reaches the outflow. https://doi.org/10.2514/6.2014-2923

#introduction

I’m Chanda Prescod-Weinstein, a theoretical physicist and feminist theorist with research specialties on dark matter, neutron stars, and Black feminist science, technology, and society studies. I’m a columnist for New Scientist and also author of an award-winning book The Disordered Cosmos: A Journey into Dark Matter, Spacetime, and Dreams Deferred.

I can be found here and @chanda, and I am Vulcan at heart 🖖🏽

This morning I posted on Twitter some thoughts about how seriously we should regard the dismantling of that site. I’m re-posting my thoughts here in what I hope will be a thread (if those exist here!).
Why it's so tricky to coordinate all your friends moving to Mastodon - lessons from @cfiesler from her study of decades of migrations from platform to platform https://theconversation.com/mass-migration-from-twitter-is-likely-to-be-an-uphill-battle-just-ask-ex-tumblr-users-193677
Mass migration from Twitter is likely to be an uphill battle – just ask ex-Tumblr users

The communities that call Twitter home might decide to pack their bags. If they do, they are unlikely to be able to completely reconstitute themselves elsewhere.

The Conversation

Hi! Here's my #introduction. I'm a Research Software Engineer (#RSE) at https://www.gi.alaska.edu/. I work on the #IceSheet model #PISM (https://www.pism.io/).

Interested in #HPC, #SoftwareDevelopment, #SoftwareMaintenance, #AppliedMath, elegant #algorithms and #code.

When not at work I enjoy #cycling (#FatBiking in the winter), #running, #photography, and baking #bread.

I'm likely to write about software development and (probably less often) whatever else I find interesting.

Since it was established by an Act of Congress in 1946, scientists at the Geophysical Institute have studied geophysical processes from the center of the Earth to the surface of the sun and beyond, turning data and observations into information useful for state, Arctic and national priorities.

Jeffrey Chester argues it is time for regulation of political advertising on streaming TV in the U.S.

It’s Time for Smart Regulation of Streaming TV Election Advertising

Without regulation, the streaming TV will be a “rerun” of what we historically experienced with cable TV, says Jeffrey Chester.

Congratulations to Field van Zee and Devin Matthews (and the grater #BLIS community) on being selected for the 2023 Wilkinson Prize in Numerical Software. This prize is awarded once every 4 years. BLIS (https://github.com/flame/blis) provides a clean separation of concerns for high performance dense #LinearAlgebra, with minimal arch-specific code to achieve top performance across hardware, and enabling sharp analytic modeling.
