pipx is a command-line tool that allows you to run Python applications in isolated environments. It's a great way to make VisiData available across your system without worrying that its dependencies will conflict with other Python projects. This short guide will show you how.
If you have have previously VisiData installed globally, uninstall it by running pip3 uninstall visidata.
Otherwise, you can skip this step.
I do the following on a per project basis.
If you don't have virtualenv installed, install it globally by running pip install virtualenv from any folder. If that didn't work because you have no pip try pip3 install virtualenv instead.

While attempting to explain JavaScript's reduce method on arrays, conceptually, I came up with the following - hopefully it's helpful; happy to tweak it if anyone has suggestions.
JavaScript Arrays have lots of built in methods on their prototype. Some of them mutate - ie, they change the underlying array in-place. Luckily, most of them do not - they instead return an entirely distinct array. Since arrays are conceptually a contiguous list of items, it helps code clarity and maintainability a lot to be able to operate on them in a "functional" way. (I'll also insist on referring to an array as a "list" - although in some languages, List is a native data type, in JS and this post, I'm referring to the concept. Everywhere I use the word "list" you can assume I'm talking about a JS Array) This means, to perform a single operation on the list as a whole ("atomically"), and to return a new list - thus making it mu
Following on Chris Whong's excellent writeup of how to make calls directly to NYC's Geosupport client and this first attempt at generalizing it, here's a way that let me geocode about 10,000 addresses a second on Ubuntu using Node FFI.
Note: this assumes Ubuntu - other Linux is probably fine but may need adjustments.
First, install the basics:
# Update, install Node and unzip (if needed)| /* -------------------------------------------- | |
| * | |
| * Main.js | |
| * Install browserify dependencies with `npm install --save <package name>` | |
| * e.g. `npm install --save d3 | |
| * | |
| * -------------------------------------------- | |
