Introducing Create ML

• Focus on images, text and tabular data
• Folders as labels, images as data for that label
• Transfer learning is used in Create ML by using an existing image classifier, augmented with your data
• This is a real quick way of training
• Playground is used to provide a UI for machine learning
• MLModelImageClassifierBuilder
• Available on Mojave

What’s new in ARKit 2

• Relocalization from 11.3 allows a session to be restored. Uses a map that is supplied by world tracking.
• In iOS 12 you can get a mapping of a physical 3D space
• Mutable list of named anchor so you can add your own anchors
• Raw feature points and extent
• World maps can be serialized (Codable?)
• The world map can be loaded again when the user starts their AR experience.

Multi-user experiences

What’s new in Cocoa Touch

Table view

• Look at expensiveness of tableView(_:cellForRowAt:), often quite expensive.
• layoutSubviews for cells can be quite expensive too.
• Prefetching can be a big win, but not always
• Two cells could be fighting for the CPU with prefetching. iOS 12 is smarter about this.
• Better CPU ramping up

Automatic Backing Store

$(document).ready(function() {
    // Elke click handler krijgt een event object als argument binnen.
    // Dit event object bevat informatie of de click die gebeurt is, zoals
    // bijvoorbeeld het elemenet waarop geklikt is. Dit object is bereikbaar
    // via de target property van het event object. Als je die in een jquery
    // dollar ding wrapt kun je dus ook de hide functie aanroepen. Daarmee hide
    // je dus het plaatje waarop geklikt is in plaats van alleen de eerste :)
    $("img").click(function(event) {
        $(event.target).hide();
    });

Basic commands

If you're not sure how to use a command or what options it has you can always do: 'man :command_name' to see the manual for that command (example: man cd)

Folders

• Switching folders: cd :folder_name:
• Move up one folder: cd ..
• Going to the home folder: cd ~
• See folder contents: ls
• See readable folder contents: ls -la (-la are options for the ls command)
