Ha ha and I see I forgot to mention the new --tred flag in the README section that explains the value of transitive reduction in https://pypi.org/project/findimports/

Also, there was a bugfix where findimports used to get confused about modules called packagename.__init__ and not realize that other modules using from packagename import thing might've been importing things from packagename.__init__.

Now these are recognized and shown as packagename without the __init__ suffix.

(This is not backwards-compatible hence the version number bump to 3.0.0.)

Previously I always used graphviz's tred to preprocess the import graph produced by findimports to get this, but now findimports can do it by itself.

Compare the same graph without transitive reduction:

findimports 3.0.0 is out with bugfixes and improvements.

It can now do a transitive reduction of your Python import graph, making them much more readable in graphviz. Eg..

uvx findimports -q -N --tred -d ~/src/check-python-versions/src -R check_python_versions | xdot -

New footgun found: repeatedly calling readline.read_history_file() and readline.write_history_file() without a readline.clear_history() in between causes exponential history size growth.

108171003 lines of pdb history take only 2 GB of disk space, but when loaded into memory, somehow causes Python's VIRT usage to spike from 500 MB to 16 GB within a dozen seconds.

Stuffing JSON into tmux paste buffers is an acceptable persistance engine for a python program, right?

Should terminals have an "undo close tab" command that restores a closed tab with full scrollback? (Yes, they should. I don't expect it to restore running programs like the shell or anything, just let me copy/paste the scrollback.)

TIL that on Windows

python -m pip install ... -cconstraints.txt

does not work, while

python -m pip install ... -c constraints.txt

works fine. The reported error is a strange FileNotFound for 'constraints' with no .txt extension.

Somebody wants to explain this to me? Because I've no idea.

Life without a CPU usage meter on screen means I only discover background jobs when my laptop gets hot.

(I've had bad a experience with the GNOME system monitor extension so I uninstalled it.)

"Ubuntu 25.04 introduces GNOME 48 with triple buffering for smoother
performance" but I thought the tripple-buffering patch was part of Ubuntu's gnome-shell build for years now?

LVM tools basically read some metadata from on-disk structures and set up the kernel's device-mapper to map ranges of sectors to various devices.

Device mapper doesn't map sectors to devices directly but rather to named targets that can be "linear" (a straight mapping to another device with some added offset) or "raid" (which uses mdraid code).

Learning how LVM works is fascinating.

The problem with buying USB cables is that when you buy them you don't know whether they're gonna be any good, and when you've finally identified which cables are good, you no longer remember where you bought them.

https://tox.wiki/en/latest/faq.html#testing-end-of-life-python-versions is very helpful, except where tox now creates a .tox/.pkg virtualenv using Python 3.12 to run pyproject_api to run setuptools.build_meta, and this venv ends up with setuptools version 65.6.3, which doesn't support Python 3.12.

I think setuptoos 65.6.3 is the one bundled with virtualenv 20.22?

I don't know how to ask tox to please pip install -U setuptools inside the .pkg virtualenv before it tries to run pyproject_api. Or how to use a different Python for .pkg.

Doing computer crimes again (tying to get modern Python tools like tox and uv handle a legacy Python 2.7 project).

/home/mg/.vim/bundle/command-t/ruby/command-t/lib/command-t/controller.rb:364: warning: undefining the allocator of T_DATA class Vim::Window

waaah why _why_ does everything break on the same day?

(at least this seems like a harmless warning rather than an error; command-t continues to work afterwards).

URLs in plaintext emails that are over 80 characters long.

The best part is that most of the 5-line URL is taken up with a query parameter called 'tracking_data'.
