Fixing pip when even `pip --version` fails

A very common failure pattern of pip is the following:

> pip --version
/usr/local/bin/pip:6: DeprecationWarning: pkg_resources is deprecated as an API. See
  from pkg_resources import load_entry_point
Traceback (most recent call last):
  File "/opt/homebrew/lib/python3.11/site-packages/pkg_resources/", line 631, in _build_master
  File "/opt/homebrew/lib/python3.11/site-packages/pkg_resources/", line 968, in require
    needed = self.resolve(parse_requirements(requirements))

Setting up deDRM with Calibre

Go to apprenticeharper/DeDRM_tools and download the latest release.

Follow the plugin's installation instructions:

Open calibre's Preferences dialog. Click on the "Plugins" button. Next, click on the button, "Load plugin from file". Navigate to the unzipped DeDRM_tools folder, find the file "". Click to select the file and select "Open". Click "Yes" in the "Are you sure?" dialog box. Click the "OK" button in the "Success" dialog box.

Once the DeDRM plugin appears in the Calibre plugins menu, double-click it to get the Customise DeDRM popup. From there, click "eInk Kindle ebooks".

Add the serial number for your preferred Kindle (the one you intend to download files for) via the Manage Your Content and Devices section of the Amazon site (instructions here).

We're going to be calling into Python from Bun, so ensure that you have Python 3 and Pip and install these packages for Python:

Creating an Expo app in 2023

12th July, 2023. I'm going to try creating an iOS app called Paranovel, using Expo. My environment for mobile app dev (Xcode, Ruby, etc.) should be in reasonably good shape already as I frequently develop with React Native and NativeScript.

Creating the app

Go to, and see the Quick Start: npx create-expo-app paranovel

This runs with no problem, then I get this macOS system popup:

How to install pip and six on macOS with Nix and home-manager

Given the following Nix packages (you may be able to install six manually rather than managing it by Nix, but anyway, this was my setup):


I would very often run into this situation:

How NativeScript's JS->native bindings work

[Draft] Deep-dive: How NativeScript's JS->native bindings work

What is NativeScript?

NativeScript is a JavaScript runtime that allows you to write an iOS or Android app entirely in TypeScript or JavaScript with no compromises. That is to say, it provides you with the same level of native access that writing the app in Obj-C/Swift (for iOS) or Java/Kotlin (for Android) does. Not just JSON-serialisable data types like NSString, but all data types are supported. To illustrate what it's all about, here's how you would get the battery level using NativeScript (the below snippet is entirely JS code!):

import { isIOS, isAndroid, Application } from "@nativescript/core";
