Only way I managed to install it was to compile it myself. Any other way I would only keep getting a recursive dependency error, with ChromaPrint requiring FFmpeg and FFmpeg requiring ChromaPrint.

# start clean. make sure you have xcode installed and all the other basics such as brew.
brew uninstall --force ffmpeg chromaprint amiaopensource/amiaos/decklinksdk

# installs ffmpeg vanilla as dependency
brew install chromaprint amiaopensource/amiaos/decklinksdk

Problem

I have two Github accounts: oanhnn (personal) and superman (for work). I want to use both accounts on same computer (without typing password everytime, when doing git push or pull).

Solution

Use ssh keys and define host aliases in ssh config file (each alias for an account).

How to?

1. Generate ssh key pairs for accounts and add them to GitHub accounts.

    var EVENT_TYPES = {
        DRAG_END: 'dragend',
        DRAG_START: 'dragstart',
        DROP: 'drop'
    }

    function createCustomEvent(type) {
        var event = new CustomEvent("CustomEvent")
        event.initCustomEvent(type, true, true, null)

Our team had interesting case with material dialog. We are working on common components, that are used by other teams and our goal is to simplify the development process. The problem was that the material dialogue does not support transclude (<ng-content>). To solve the problem created a separate DialogContentComponent, that is passed into

    this.dialogRef = this.dialog.open(DialogContentComponent, {disableClose: true})

that is inside of DialogComponent. DialogContentComponent has a template of the dialog, which should be everywhere the same, and in DialogComponent template we have only this:

Directives can be used as interceptors on the input before the model changes. Here is an example of such a directive:

@Directive({
	selector: '[myValueChangeInterceptor]',
	providers: [NgModel]
})
export class InputInterceptorDirective {
	@Input() public myValueChangeInterceptor: (value: string) => string;
	@Output() public valueInput: EventEmitter<string> = new EventEmitter();

Outdated note: the process is a lot easier now: after you brew install postgresql you can initialize or stop the daemon with these commands: brew services start postgresql or brew services stop postgresql.

new out put may look like

To have launchd start postgresql now and restart at login:
  brew services start postgresql
Or, if you don't want/need a background service you can just run:
  pg_ctl -D /usr/local/var/postgres start
