Google Chrome Favicons For Bookmarklets

Open the Bookmark Manager and export your bookmarks;
Open the exported html file in your favorite editor and look for the bookmarklet you want a favicon applied to;
Convert the 16x16 px (or greater) favicon you want to use into the BASE64 format (I used Base64 Image Encoder);
Now you can add the favicon via adding the ICON="data:image/insert-your-base64-image-code-here" attribute in the link;
Save the file and import it in the bookmark manager.

Done! If the favicon doesn’t show up, try clicking on the bookmarklet. Afterwards the changes should stick and you can delete the imported bookmarks folder. If you have sync activated the favicons on your bookmarklets will also show up on your other PC, Mac, smartphone etc.

Raspberry Pi Zero OTG Mode

Simple guide for setting up OTG modes on the Raspberry Pi Zero - By Andrew Mulholland (gbaman).

The Raspberry Pi Zero (and model A and A+) support USB On The Go, given the processor is connected directly to the USB port, unlike on the B, B+ or Pi 2 B, which goes via a USB hub.
Because of this, if setup to, the Pi can act as a USB slave instead, providing virtual serial (a terminal), virtual ethernet, virtual mass storage device (pendrive) or even other virtual devices like HID, MIDI, or act as a virtual webcam!
It is important to note that, although the model A and A+ can support being a USB slave, they are missing the ID pin (is tied to ground internally) so are unable to dynamically switch between USB master/slave mode. As such, they default to USB master mode. There is no easy way to change this right now.
It is also important to note, that a USB to UART serial adapter is not needed for any of these guides, as may be documented elsewhere across the int

	// A minimal polyfill for copying text to clipboard that works most of the time in most capable browsers.
	// Note that:
	// - You may not need this. `navigator.clipboard.writeText()` works directly in all modern browsers as of 2020.
	// - In Edge, this may call `resolve()` even if copying failed.
	// - In Safari, this may fail if there is nothing selected on the page.
	// See https://github.com/lgarron/clipboard-polyfill for a more robust solution.
