If you're writing a tutorial on managing Python dependencies for an application, be sure to add this line: "As soon as you pin one dependency, you must pin the entire dependency tree." So many people pin their direct dependencies, and then get confused why things are incompatible a few years later. #Python

The video of my tutorial on Bayesian Decision Analysis, from PyData Global 2022, is available now.

CPython bug: https://github.com/python/cpython/issues/69121
someone could fix this! probably not super hard.

I learned again that I know nothing about network programming :-(

Pleased to announce our son was born alive and healthy two weeks ago ❤️

Okay, so, I made a thing.

I do not actually expect anyone to sign up for this in its current state, but the point is that it's up, it's live, and I can now maybe begin the gradual transition from "internet vagrant" to "internet busker".

The main thing this gets you is the ability to create a vague sense of inadequacy and dread that I'm not giving you your money's worth, so, please go ahead and stress me out.

Has anyone ever heard of software that takes an epub, divides it up into chunks and then creates an RSS feed of those chunks dated at regular intervals? That way you could read a book alongside your blogs in your new reader. If not, should I make a thing like this?

I think I read about something similar that turns audiobooks into podcast feeds.

Boosts welcome

Inspired by @mkennedy, and the work I'm doing on profiling for Python data processing jobs, some initial scattered thoughts on how performance differs between web applications and data processing, and why they therefore require different tools.

1. Web sites are latency-focused. Web applications typically require very low latency (milliseconds!) from a _user_ perspective. Throughput matters from website operator perspective, but it's more about cost.

Just did first pass of fork()-based multiprocessing profiling for Sciagraph (https://sciagraph.com), a profiler for #Python #datascience pipelines.

First test passed, now to polish it up.

Notes:

1. In case you are not aware, #Python's `multiprocessing` on Linux is BROKEN BY DEFAULT (https://pythonspeed.com/articles/python-multiprocessing/).
2. As a result, this code is quite evil.
3. I am so so happy I am writing software in #Rust. Writing a robust profiler of this sort in C++ would've been way beyond my abilities.

The release candidate for tox 4 - a complete rewrite of the project - is now out; see https://tox.wiki/en/rewrite/changelog.html#v4-0-0rc1-2022-11-29. Please try it because if no show-stoppers are reported, will be a stable release on the 6th of December 2022. I'd hate to break your CI, so test it beforehand. 😀Thanks! https://pypi.org/project/tox/4.0.0rc1/
