Tell Git not to track a file any more (remove from repo)

git rm --cached [filenames]

Here’s how I removed all the files I wanted to delete from one of my bin subdirectories:

git rm --cached bin/com/devdaily/sarah/\*

I use the unusual * syntax at the end of that command instead of * because you need to escape the * from the git command. In a simpler example, if there was just one file in the bin directory named Foo.class that I wanted to remove from the Git repository, I would use this command:

Tried creating and installing needed packages into a virtual python environment, but Jupyter notebook would still throw Module not found errors, even after pip, pip3 on base installation, as well as pip, pip3 install method into the virtual environment.

conda create -n my-conda-env         # creates new virtual env
source activate my-conda-env         # activate environment in terminal
conda install jupyter                # install jupyter + notebook
jupyter notebook                     # start server + kernel

To solve, in jupyter notebook, run:

exFAT support on macOS seems to have some bugs because my external drives with exFAT formatting will randomly get corrupted.

Disk Utility is unable to repair this at first, but the fix is this:

1. Use diskutil list to find the right drive id.
2. You want the id under the IDENTIFIER column, it should look like disk1s1
3. Run sudo fsck_exfat -d <id from above>. eg sudo fsck_exfat -d disk1s3
4. -d is debug so you'll see all your files output as they're processed.
5. Answer YES if it gives you the prompt Main boot region needs to be updated. Yes/No?

TiddlyWiki: Getting Started with digital gardens, networked thinking and non-linear research

Overview

We will be diving into the Tiddlywiki framework (TW), which is an open-source tool great for compiling notes, research, bookmarking, and making non-linear and personalized knowledge maps. In my case I used it to build a virtual portfolio and bookcase for logging my reading notes and keeping track of my projects.
