Idea

Create an quiz app using Trivia API.

General requirements

Use Trivia Api
One question visible on the screen at once
Ability to go back to any question and change given answer - if quiz is not finished
Showing progress of the quiz
After submitting there should be a summary with the chart (for example correct to incorrect answers ratio, few last quizzes results, time spent on each question or any other statistic)
Application should be responsive and work on desktop, tablet and mobile devices

psql: FATAL: Peer authentication failed for user “postgres” (or any user)

The connection failed because by default psql connects over UNIX sockets using peer authentication, that requires the current UNIX user to have the same user name as psql. So you will have to create the UNIX user postgres and then login as postgres or use sudo -u postgres psql database-name for accessing the database (and psql should not ask for a password).

If you cannot or do not want to create the UNIX user, like if you just want to connect to your database for ad hoc queries, forcing a socket connection using psql --host=localhost --dbname=database-name --username=postgres (as pointed out by @meyerson answer) will solve your immediate problem.

But if you intend to force password authentication over Unix sockets instead of the peer method, try changing the following pg_hba.conf* line:

from

	/**
	* Generate a CSV of all the routes
	*/
	Route::get('r', function()
	{
	header('Content-Type: application/excel');
	header('Content-Disposition: attachment; filename="routes.csv"');

	$routes = Route::getRoutes();
	$fp = fopen('php://output', 'w');

	<?php
	// routes/console.php

	// quickly create an user via the command line
	Artisan::command('user:create', function () {
	$name = $this->ask('Name?');
	$email = $this->ask('Email?');
	$pwd = $this->ask('Password?');
	// $pwd = $this->secret('Password?'); // or use secret() to hide the password being inputted
	\DB::table('users')->insert([

	//GetTransactionsAndLinesForBidder hits the database 3 times. Let's make that fast.
	func (db *DB) GetTransactionsAndLinesForBidder(bidderID int) ([]BidderTransaction, error) {

	//Establish a waitgroup. This has 3 functions only. Add, Wait, and Done. You add to the WaitGroup and hit Done when you are
	// done with a process. It will stop the function at Wait until the WaitGroup is at 0.
	var wg sync.WaitGroup

	//Get the transaction 'shell'
	trans, err := db.GetTransactionsForBidder(bidderID)
	if err != nil {

	Fix by setting the executable flag on your gradlew file.

	chmod +x gradlew (on unix systems)
