I am in a pub in a small town in the countryside. The group of old men in the corner (these pubs ALWAYS have a group of old men in the corner) are having a vigorous argument about Brexit. I'm not sure they realise it's 2025 not 2015.

An early morning alone on the banks of the (still young) Isar river some weeks ago... Really more "flow" rather than #WaterfallWednesday, but I just absolutely cherish places and moments like this & feeling so privileged being able to experience these after decades of living in large cities... (each time also a reminder how much we stand to lose...)

If the new Pope is a true lion he'll excommunicate all Catholic SC justices. This wouldn't only be the right thing to do but also incredibly funny.

Tonight our pop-jazz choir, Sing'n'Swing, had its first public concert in two years. We changed choir directors about a year-and-a-half ago. The concert went well. I sang a small solo, which also went well. A number of people told me I killed it. I took that as a good thing. 😃 Here's a post-concert photo.

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".

The built in calculator app on the iPhone can do all sorts of conversions.
Long-press the icon at bottom left and you get a pop-up menu. Slide the toggle on and the default $ to € currency converter appears. There’s a bazillion other currencies available too. But you can also choose among 15 other unit conversions, like weights, energy, force, pressure.

Für die Samstagsnachmittagscrew nochmal der Link auf meine SF-/F-Lektüre aus dem Juni 2025 ... das eine oder andere wäre vielleicht auch als Urlaubslektüre geeignet.
