Underprepared for Physics: Reframing the narrative on readiness and instruction in calculus-based, introductory physics courses
In the U.S., introductory calculus-based courses often acts as a gatekeeper to STEM degrees. But access to the prerequisite math is far from equal--students from low-income and racially marginalized communities are far less likely to have the chance to take calculus before college. These disparities are then compounded by rigid placement systems that reward procedural fluency in algebra and trigonometry, while overlooking the conceptual quantitative reasoning that physics truly demands.

Tip for #FlyingLess as a family: prepare for long train rides with board card games. The #privacy friendly app games by @… are absolutely brilliant, easy to use, stable not stealing your data (or trying to sell your kids stuff).

Tänk er ett samtal där du ställer en fråga, får ett svar och sen lägger personen på. Har den missförstått frågan måste du starta ett nytt samtal, men den som svarar denna gång vet inte varför du fick det svar du fick förra gången och svarar helt sonika någonting annat... och lägger på.
Låter det frustrerande?
Det är det!
Öppnar mitt tredje 'samtal' med denna text - är jag för hård?

In case anyone here has connections with the Python team: can you please tell them to update their docs on XML security? The way it is is quite misleading, and it's been annoying me for a while. I raised this a while ago in their issue tracker, but it got no reaction whatsoever. https://github.com/python/cpython/issu…

Some fun facts about #Python limited API / stable ABI.
1. #CPython supports "limited API". When you use it, you get extensions that are compatible with the specified CPython version and versions newer than that. To indicate this compatibility, such extensions use `.abi3.so` suffix (or equivalent) rather than the usual `.cpython-313-x86_64-linux-gnu.so` or alike.
2. The actual support is split between CPython itself and #PEP517 build systems. For example, if you use #setuptools and specify `py_limited_api=` argument to the extension, setuptools will pass appropriate C compiler flags and swap extension suffix. There's a similar support in #meson, and probably other build systems.
3. Except that CPython freethreading builds don't support stable ABI right now, so building with "limited API" triggers an explicit error from the headers. Setuptools have opted for building explicit about this: it emits an error if you try to use `py_limited_api` on a freethreading interpreter. Meson currently just gives the compile error. This implies that package authors need to actively special-case freethreading builds and enable "limited API" conditionally.
4. A some future versions of CPython will support "limited API" in freethreading builds. I haven't been following the discussions closely, but I suspect that it will only be possible when you target that version or newer. So I guess people will need to be building two stable ABI wheels for a time — one targeting older Python versions, and one targeting newer versions plus freethreading. On top of that, all these projects will need to update their "no 'limited API' on freethreading" conditions.
5. And then there's #PyPy. PyPy does not feature a stable ABI, but it allows you to build extensions using "limited API". So setuptools and meson just detect that there is no `.abi3.so` on PyPy, and use regular suffix for the extensions built with "limited API".
