jq: JSONL → TSV conversion

What is TSV?

TSV means "tab-separated values". I prefer this format over CSV ("comma-separated values") because it doesn't require as much quoting. Many programs that can use CSV formatted data can also use TSV, although they may need to be explicitly told of the different format if it's not detected automatically.

However, in any of the jq scripts below, "@tsv" can usually be replaced with "@csv" to get CSV output instead.

How To - Upload and add Images to markdown files in Gist

Markdown files allow embedding images in it. However it requires the image to be hosted at some location and we can add the url of the image to embed it.

Example: ![Alternate image text](https://someurl/imagelocation/image.png)

We can use services like imgur or other services to host the images and use the hosted URL.

Ubuntu 16 default python is almost python 3

Loads of solutions exist, but for changing the system default, alias is not the way to go.
