Here is the process how sys.path is set in Python, with some parts omitted.

Python Command Line Arguments

By default, as initialized upon program startup, a potentially unsafe path is prepended to sys.path:

python -m: prepend the current working directory.

python script.py: prepend the script’s directory. If it’s a symbolic link, resolve symbolic links.

python -c and python (REPL): prepend an empty string, which means the current working directory.

You can remove these path with -P param.

It’s known that Python’s import statement is implemented by __import__ function. In general, if we want to import a module dynamically, we can use import_module function, which is a wrapper around __import__.

The most important difference between these two functions is that import_module() returns the specified package or module (e.g. pkg.mod), while import() returns the top-level package or module (e.g. pkg). – https://docs.python.org/3/library/importlib.html#importlib.import_module

The disk performance in WSL2 is poor, it takes a long time to run git status in a host’s repo. Moreover, if you set a fancy shell prompt, it will take a long time to show the prompt. This article will introduce how to speed up Git in WSL2.

How to speed up Git Command

The performance of file system in WSL2 is poor, it takes a long time to run git status in a host’s repo. The solution is to use git.exe in Windows folder. You can add this into your bashrc:

I bought a iPod Video 5.5th Gen 80G recently. It’s only 200 Yuan (about $30) and I’m satisfied with it.

Rockbox

The original firmware supports few audio format, it even can’t play FLAC. I install rockbox on it, which support FLAC and other format and I can transfer music without using iTunes or Finder. It also support theme and plugin, which makes it more powerful.

MacPod error

If you restore the iPod on macOS, it raises Warning: This is a MacPod, Rockbox only runs on WinPods. See http://www.rockbox.org/wiki/IpodConversionToFAT32 during installation. The easiest way to fix this is to restore it on Windows.

In [Packaging] Support Python 3.11 by bebound · Pull Request #26923 · Azure/azure-cli (github.com) , I bumped azure-cli to use Python 3.11. We’ve bump the dependency in other PRs, I thought it should be a small PR, but in the end, a lot of changes are made.

args.getargspec

getargspec is dropped in 3.11. You can easily replaced it with getfullargspec . It returns FullArgSpec(args, varargs, varkw, defaults, kwonlyargs, kwonlydefaults, annotations) instead of ArgSpec(args, varargs, keywords, defaults) So args, _, kw, _ = inspect.getargspec(fn) can be replaced by args, _, kw, *_ = inspect.getfullargspec(fn) However, getfullargspec is retained primarily for use in code that needs to maintain compatibility with the Python 2 inspect module API.

When working on a project with multiple developers, the line ending can be troublesome. This article will explain how to configure line ending in Git.

Basic configuration

The line ending on Windows is CRLF, on Linux is LF. To prevent the line ending issue, we can set core.autocrlf to true on Windows to let git convert CRLF to LF when commit, and convert LF to CRLF when checkout. It is automatically configured if you install git on Windows.
