Always Already Programming

Everyone who interacts with computers has in important ways always already been programming them.

Every time you make a folder or rename a file on your computer, the actions you take through moving your mouse and clicking on buttons, translate into text-based commands or scripts which eventually translate into binary.

Why are the common conceptions of programmer and user so divorced from each other? The distinction between programmer and user is reinforced and maintained by a tech industry that benefits from a population rendered computationally passive. If we accept and adopt the role of less agency, we then make it harder for ourselves to come into more agency.

We've unpacked the "user" a little, now let's look at the "programmer." When a programmer is writing javascript, they are using prewritten, packaged functions and variables in order to carry out the actions they want their code to do. In this way, the programmer is also the user. Why is using pre-made scripts seen

Signing VirtualBox Kernel Modules

These are the steps I followed enable VirtualBox on my laptop without disabling UEFI Secure Boot. They're nearly identical to the process described on [Øyvind Stegard's blog][blog], save for a few key details. The images here are borrowed from the [Systemtap UEFI Secure Boot Wiki][systemtap].

1. Install the VirtualBox package (this might be different for your platform).

Instructions

The URL https://git.io/this-time-for-real-tho links to the win10-usb.sh script below. It created something bootable from my Fedora 29 workstation.

Try to run

curl -L https://git.io/this-time-for-real-tho | sh

and if that doesn't work try explicitly setting an environment variable for the location of the .iso file

The Python here works just fine, but mypy doesn't like it...

example.py:14: error: Argument 1 to "callback" has incompatible type "Optional[str]"; expected "str"

The if url is None: conditional should prevent the url in the else block from ever being None, but maybe it doesn't work like that? Or I'm just wrong...

This is perfectly fine Python. It outputs

Opening...
Opening...
1337
Closing...

when run, but Mypy complains...

example.py:29: error: Incompatible default for argument "cls" (default has type "Type[Concrete]", argument has type "SupportsOpenClose")
