How to recover a dropped stash in Git?

1. Find the stash commits:

git log --graph --oneline --decorate $( git fsck --no-reflog | awk '/dangling commit/ {print $3}' )

This will show you all the commits at the tips of your commit graph which are no longer referenced from any branch or tag – every lost commit, including every stash commit you’ve ever created, will be somewhere in that graph.

What could I try for doing Test Impact Analysis for Python projects?

Answer:

There are a few libraries out there you could try. Here are some entrypoints:

blog draft: continuous learning is the keystone habit of software development. oh, and the other part: you have to get over yourself!
View continuous_learning_inflection_point.md

I've self-educated as a developer; now almost 10 years into it, it's worked out for me. But why? What was the deciding factor?

Looking back, I think I can see the inflection point.

I had a mentor who helped me use interactive approaches, and test-driven development. This led to a test-driven mindset.

The core of this mindset is the empirical attitude: that you can know nothing without testing. I learned to iterate in a more directed way. And by always beginning with failing tests,

hangtwenty / SanitizedString.py
Last active Sep 6, 2017
(OLD; newer version is here: https://github.com/hangtwenty/presswork/blob/master/presswork/text/clean.py ) I wanted to "ensure" strings had been sanitized (avoid running redundantly). This is ONLY ONE type of sanitization, removing control chars (BESIDES NEWLINES), because that is what my current project needed. But I thought the design could be…
View SanitizedString.py
""" throw your strings to SanitizedString and "ensure" they have been sanitized, such as removing control characters.
SanitizedString will avoid running redundantly, by checking type of the input (good for Very Big Strings)
>>> hello = SanitizedString(chr(0) + "hello")
>>> assert hello == "hello"
>>> assert chr(0) not in hello
>>> assert SanitizedString(hello) == hello
at time of writing there is only one sanitization filter in use:

fix that pesky "ImportError: No module named packaging.version" problem. Or more generally, if you need to fix pip using pip, just make sure you do "python -m pip" instead of straight-up "pip".
View _fix_pip_import_error.md

It can come up while installing anything really. I'm not sure exactly which versions of pip are affected, I know I had 1.5.6 and it was affected.

These examples are grabbed from my system level Python, but of course you should use a virtualenv.

  Running setup.py install for simplegeneric
    Traceback (most recent call last):
      File "<string>", line 1, in <module>
      File "/Library/Python/2.7/site-packages/setuptools/__init__.py", line 12, in <module>
        import setuptools.version
You can’t perform that action at this time.
