What's a Uniform Type Identifier?

Each UTI provides a unique identifier for a particular file type, data type, directory or bundle type, and so on. In addition, other type identifier namespaces for a particular type can be grouped under one UTI, with utility functions available to translate from one format to another.

What's the table below?

The following tables list uniform type identifiers (UTIs) that are declared by the system as of OS X v10.4. [Which was released in 2005. That means it's NOT up to date. Apple Developer stuff has the up to date docs. Still, these can be useful for scripting, Alfred Workflows, and so on.]

ESP32 as Bluetooth Keyboard

With its built-in Bluetooth capabilities, the ESP32 can act as a Bluetooth keyboard. The below code is a minimal example of how to achieve it. It will generate the key strokes for a message whenever a button attached to the ESP32 is pressed.

For the example setup, a momentary button should be connected to pin 2 and to ground. Pin 2 will be configured as an input with pull-up.

In order to receive the message, add the ESP32 as a Bluetooth keyboard of your computer or mobile phone:

1. Go to your computers/phones settings
2. Ensure Bluetooth is turned on

// FindMode - phoenix binding for an interactive window-finding mode
//  * bind to a key by calling the instance's 'bind' method, which has the
//    same first two args as phoenix's Phoenix.bind() call.  The third argument
//    is an array of other key bindings which should be temporarily disabled
//    while in the FindMode mode.
//  * while in Find mode:
//      - hit escape to exit the mode (todo: and restore the window stack)
//      - type a regex to interactively auto-raise the first window that matches
//      - backspace to remove chars from the regex
//      - hit tab to cycle to the next matching window for the current regex

What forces layout / reflow

All of the below properties or methods, when requested/called in JavaScript, will trigger the browser to synchronously calculate the style and layout*. This is also called reflow or layout thrashing, and is common performance bottleneck.

Generally, all APIs that synchronously provide layout metrics will trigger forced reflow / layout. Read on for additional cases and details.

Element APIs

• elem.offsetLeft, elem.offsetTop, elem.offsetWidth, elem.offsetHeight, elem.offsetParent
