Example: difference between ddl and dml DDL 1-It stands for Data Definition Language. 2-It is used to create database schema and can be used to define some constraints as well. 3-It basically defines the column (Attributes) of the table. 4-It doesn’t have any further classification. 5-Basic command present in DDL are CREATE, DROP, RENAME, ALTER etc. 6-DDL does not use WHERE clause in its statement. DML 1-It stands for Data Manipulation Language. 2-It is used to add, retrieve or update the data. 3-It add or update the row of the table.

Answer : ... a solution for windows: 1) Browse to the VLC folder, e.g. C:\Program Files (x86)\VideoLAN\VLC , and create a new folder called visualizations 2) Download the latest preset_samples of ProjectM, e.g. presets-2.0.0-Source.tar.gz and extract all the .milk files to the visualizations folder created above. 3) In VLC open Preferences from the menu, go to the audio tab and under Output select "Directx audio output" as your Output module. Also make sure that "LibprojectM effect" is selected as your Visualisation. 4) Still in the Preferences menu, click the "All" radiobutton at the bottom left corner.

Answer : You should be able to reuse Content Scripts from your Web-Extensions (but you need to rewrite code to be able to send/receive messages with "background"). Background script will have to be re-written in Swift or Objective-C. You need to developp: a Mac Host Application (which will be a companion to the Extension) : Swift or Objective-C (this app must have minimum features to pass Apple review - check the Apple guidelines for Mac Apps) the extension : in Swift or Objective-C + HTML/JS (as for other browsers) The code in Swift (or Obj-C) for the extension is the equivalent of the background page you have in Web Extensions. It will control the toolbar button, life-cycle of the extension and can talk with injected scripts. You have an (small) example on Apple website : https://developer.apple.com/documentation/safariservices/safari_app_extensions?changes=_2&language=objc You should not use Extension Builder anymore (accessible from Developer menu in Safari) since
