Matrix multiplication refresher: develop your intuition for matrix multiplication! (Or, "matrix multiplication for dummies")

A refresher on matrix multiplication. Because your math classes were years ago. Here's the order I recommend:

  1. TED-Ed video — How to organize, add and multiply matrices - Bill Shillito (only 5 minutes)
  2. betterexplained.com — "An Intuitive Guide to Linear Algebra" by Kalid Azad
  3. mathinsight.org: "Matrices and linear transformations"
  4. Read some of the answers on math.stackexchange.com. You've been studying the general definition of matrix multiplication. You may wonder: "Are there other ways to define the product of two matrices?" These resources will answer, yes, there are other ways, but also explain why this general definition is the standard way.

floer32 / sonarqube and gradle and analysis mode.md
Last active March 22, 2018 16:52
little note regarding sonarqube and gradle

SonarQube not "uploading"? Be careful about sonar.analysis.mode=issues (or, if using Gradle, systemProp.sonar.analysis.mode=issues). This analysis mode seems required for some purposes (some plugins maybe?), but it was making Gradle not generate the report or upload it to SonarQube server. I haven't figured out the details yet but I wanted to leave this memo...

floer32 / _fix_pip_import_error.md
Last active June 24, 2022 10:44
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".

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>

floer32 / SanitizedString.py
Last active September 6, 2017 17:53
(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…
""" 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:
