I think audit hooks were a great idea and are part of a defence-in-depth strategy. In fact, I even implemented the variant of audit hooks that informed PEP-551 and deployed those to production for a major platform. I think that if you were

Embedding Python 2 inside of Python 3 (or vice-versa) is not very hard to do on Linux. Simply `dlmopen` the .so in a new linker namespace and write a little bit of bridging code to interface the two object layouts. Python has a very rich ru

I would love to find a comparable device from a vendor that prioritises Linux support. As far as I can tell, none such exist. There are many companies making "detachable"/"type cover" tablet devices, but I can'

There are, as far as I can tell, no Linux drivers for the OV2740 and IMX136 cameras (yet.) It's unfortunate that the Qualcomm WiFi does not work out of the box. However, the fix is fairly easy, and day-to-day WiFi performance is solid:

Some environments use code-signing as a security mechanism. Arbitrary execution via pickle creates holes in this mechanism, requiring additional mitigations. PEP-551 briefly discusses security motivations and potential mechanisms for enviro

Shell-code attacks using pickled objects have been around for some time. A pickle bytestring can execute completely arbitrary code. I have used them in my work. An easy introduction: https://www2.cs.uic.edu/~s/musings&

But tuples (and cells) are mutable in pure CPython if you believe strongly enough. See: https://gist.github.com/llllllllll/b1ac68a6b77535a64c0b13bfd... https://gist.github.com/dutc/d2ff9f17a0520d23

There's interesting overlap between tools like `cffi` and `cython`. This is one of the approaches I am pursuing to polish off something I put together recently: rapid prototyping of LD_PRELOADs in Python. I presented an early approach

Python's site module contributes a lot to this. It attempts to load a lot of other modules, many of which may not exist for a given install. Using your example: $ strace python3 -c 'print("hello world", end="&
