Here’s the Best USB-C Hub Deal…Ever?

Working and playing in the great outdoors isn’t always about camouflage and chainsaws. We gotta stay hydrated while we’re out there! And to that end, Pelican sent me one of their stainless steel vacuum tumblers to try out. After more than a year of regular use, it’s time to talk about it here.

Specifically, it’s the Pelican 22-Ounce “Traveler” tumbler. Here are some specs:

Manufacturer Specs

• Double-wall vacuum insulation
• 18/8 BPA-free stainless steel
• Copper plated inner wall
• Extreme cold & heat retention
• Guaranteed for life (“You break it, we replace it… Forever”)
• Spill-resistant lid with sliding cover
• Generous “lip” on lid keeps your lips off of the stainless steel
• Available colors: Black, OD Green, Seafoam, Stainless

It Works

I ordered my Pelican tumbler in OD Green, which is a really attractive color in my opinion. And even though my wife doesn’t usually love green, she commandeered my Pelican tumbler almost immediately. One reason is that when she drives somewhere with her sisters, this Pelican fits in cup holders where her other stainless tumbler just won’t.

Pelican claims it “fits in up to 99% of all car and truck cup holders,” and so far they’ve been correct.

The smaller portion at the base which allows it to fit so many cup holders also makes it easier to hold in your hand, and the shoulder helps prevent it from slipping down in wet (or weaker) hands.

As for ice retention, the Pelican Traveler is certainly up to snuff. Even after sitting in a closed vehicle in the hot Florida sun for hours, the Traveler still has ice inside. In fact, we had to stop filling it all the way with ice before adding water, because after drinking all the water, the ice would never melt! Being thirsty with a tumbler full of ice is no fun.

We Like the Lid

The Traveler’s lid is the best I’ve ever seen for one of these stainless vacuum tumblers. Instead of cramming it down into the tumbler and later fighting with a tight rubber seal to remove it, you just screw it on and off. Not only is it easier to put on and off — my sweetie says it doesn’t hurt her hands like other lids — but this also means the lid is not going to come flying off if you drop your Traveler.

The sliding cover is also a nice touch. This is great for dusty conditions like when you’re mowing the lawn or trail riding, and it helps prevent your drink from splashing out too.

The cover is easily removed so you can thoroughly wash it and the lid.

Our other favorite feature of the Traveler’s lid is that your mouth doesn’t touch the tumbler when you drink. The lid has a large lip or spout area, which makes it easier and more pleasant to drink from than most stainless steel tumblers.

It’s Well-Made

The Traveler is a quality product, as is every Pelican product I’ve ever tried. It’s well-made, and the powder-coat finish has held up well.

Of course, the Pelican Traveler has the same recommendations as other vacuum-insulated stainless steel vessels: Don’t freeze it, don’t microwave it, and hand-wash instead of using the dishwasher.

Conclusion

The Pelican 22-Ounce Traveler stainless steel tumbler is a well-made drinking vessel that should last for a heck of a long time. It’s well-designed and durable, easy to hold, fits in most cup holders, won’t sweat, and has the best lid around.

We sure like ours, and my wife is certain to keep her claim on this one. And that’s okay, because I’d rather have the 32-ounce model anyhow…

As I write this, the 22-ounce Pelican Traveler is available for about $20 shipped ($21 if you want green).

Build Your Own Glock Part 1. The Embryo

In this tutorial, we’ll learn how to add JWT authentication to our REST API PHP application.
We’ll see what JWT is and how it works. We’ll also see how to get the authorization header in PHP. What is JWT
JWT stands for JSON Web Token and comprised of user encrypted information that can be used to authenticate users and exchange information between clients and servers. When building REST API, instead of server sessions commonly used in PHP apps we tokens which are sent with HTTP headers from the server to clients where they are persisted (usually using local storage) then attached to every outgoing request originating from the client to the server. The server checks the token and allow or deny access to the request resource. RESTful APIs are stateless. This means that requests from clients should contain all the necessary information required to process the request. If you are building a REST API application using PHP, you are not going to use the $_SESSION variable to save data about the client’s session. This means, we can not access the state of a client (such as login state). In order to solve the issue, the client is responsible for perisiting the state locally and send it to the sever with each request. Since these important information are now persisted in the client local storage we need to protect it from eyes dropping. Enter JWTs. A JWT token is simply a JSON object that has information about the user. For example:
{
"user": "bob",
"email": "bob@email.com",
"access_token": "at145451sd451sd4e5r4",
"expire_at"; "11245454"
}
Since thos token can be tampered with to get access to protected resources. For example, a malicious user can change the previous token as follows to access admin only resources on the server:
{
"user": "administrator",
"email": "admin@email.com"
}
To prevent this situation, we JWTs need to be signed by the server. If the token is changed on the client side, the token’s signature will no longer be valid and the server will deny access to the requested resource.
How JWT Works
JWT tokens are simply encrypted user’s information like identifier, username, email and password. When users are successfully logged in the server, the latter will produce and send a JWT token back to the client. This JWT token will be persisted by the client using the browser’s local storage or cookies and attached with every outgoing request so if the user requests access to certain protected resources, the token needs to be checked first by the server to allow or deny access. What is PHP-JWT
php-jwt is a PHP library that allows you to encode and decode JSON Web Tokens (JWT) in PHP, conforming to RFC 7519.
Prerequisites
You must have the following prerequsites to be able to follow this tutorial from scratch:
You need PHP 7, Composer and MySQL database system installed on your development environment,
You need to have basic knowledge of PHP and SQL.
Creating the MySQL Database and Table(s)
If you have the prerequisites, let’s get started by creating the MySQL database. We’ll be using the MySQL client installed with the server. Open a terminal and run the following command to invoke the client:
$ mysql -u root -p
You need to enter your MySQL password when prompted.
Next, let’s create a database using the following SQL instruction:
mysql> create database db;
Note: Here we assume you have a MySQL user called root. You need to change that to the name of an existing MySQL user.
You can also use phpMyAdmin or any MySQL client you are comfortable with to create the database and SQL tables.
Let’s now select the db database and create a users table that will hold the users of our application:
mysql> use db;
mysql> CREATE TABLE IF NOT EXISTS `Users` (
`id` INT AUTO_INCREMENT ,
`first_name` VARCHAR(150) NOT NULL ,
`last_name` VARCHAR(150) NOT NULL ,
`email` VARCHAR(255),
`password` VARCHAR(255),
PRIMARY KEY (`id`) );
Creating the Project Directory Structure
Let’s create a simple directory strucutre for our project. In your terminal, navigate to your working directory and create a folder for our project:
$ mkdir php-jwt-example
$ cd php-jwt-example
$ mkdir api && cd api
$ mkdir config
We first created the project’s directory. Next, we created an api folder. Inside it, we created a config folder. Connecting to your MySQL Database in PHP
Navigate to the config folder and create a database.php file with the following code:
<?php
// used to get mysql database connection
class DatabaseService{
private $db_host = "localhost";
private $db_name = "mydb";
private $db_user = "root";
private $db_password = "";
private $connection;
public function getConnection(){
$this->connection = null;
try{
$this->connection = new PDO("mysql:host=" . $this->db_host . ";dbname=" . $this->db_name, $this->db_user, $this->db_password);
}catch(PDOException $exception){
echo "Connection failed: " . $exception->getMessage();
}
return $this->connection;
}
}
?>
Installing php-jwt
Let’s now proceed to install the php-jwt library using Composer. In your terminal, run the following command from the root of your project’s directory:
$ composer require firebase/php-jwt
This will donwload the php-jwt library into a vendor folder.
You can require the php-jwt library to encode and decode JWT tokens using the following code:
<?php require "vendor/autoload.php";
use \Firebase\JWT\JWT;
Adding the User Registration API Endpoint
Inside the api folder, create a register.php file and add the following code to create a new user in the MySQL database:
<?php
include_once ‘./config/database.php’;
header("Access-Control-Allow-Origin: * ");
header("Content-Type: application/json; charset=UTF-8");
header("Access-Control-Allow-Methods: POST");
header("Access-Control-Max-Age: 3600");
header("Access-Control-Allow-Headers: Content-Type, Access-Control-Allow-Headers, Authorization, X-Requested-With");
$firstName = ”;
$lastName = ”;
$email = ”;
$password = ”;
$conn = null;
$databaseService = new DatabaseService();
$conn = $databaseService->getConnection();
$data = json_decode(file_get_contents("php://input"));
$firstName = $data->first_name;
$lastName = $data->last_name;
$email = $data->email;
$password = $data->password;
$table_name = ‘Users’;
$query = "INSERT INTO " . $table_name . "
SET first_name = :firstname,
last_name = :lastname,
email = :email,
password = :password";
$stmt = $conn->prepare($query);
$stmt->bindParam(‘:firstname’, $firstName);
$stmt->bindParam(‘:lastname’, $lastName);
$stmt->bindParam(‘:email’, $email);
$password_hash = password_hash($password, PASSWORD_BCRYPT);
$stmt->bindParam(‘:password’, $password_hash);
if($stmt->execute()){
http_response_code(200);
echo json_encode(array("message" => "User was successfully registered."));
}
else{
http_response_code(400);
echo json_encode(array("message" => "Unable to register the user."));
}
?>
Adding the User Login API Endpoint
Inside the api folder, create a login.php file and add the following code to check the user credentials and return a JWT token to the client:
<?php
include_once ‘./config/database.php’;
require "../vendor/autoload.php";
use \Firebase\JWT\JWT;
header("Access-Control-Allow-Origin: *");
header("Content-Type: application/json; charset=UTF-8");
header("Access-Control-Allow-Methods: POST");
header("Access-Control-Max-Age: 3600");
header("Access-Control-Allow-Headers: Content-Type, Access-Control-Allow-Headers, Authorization, X-Requested-With");
$email = ”;
$password = ”;
$databaseService = new DatabaseService();
$conn = $databaseService->getConnection();
$data = json_decode(file_get_contents("php://input"));
$email = $data->email;
$password = $data->password;
$table_name = ‘Users’;
$query = "SELECT id, first_name, last_name, password FROM " . $table_name . " WHERE email = ? LIMIT 0,1";
$stmt = $conn->prepare( $query );
$stmt->bindParam(1, $email);
$stmt->execute();
$num = $stmt->rowCount();
if($num > 0){
$row = $stmt->fetch(PDO::FETCH_ASSOC);
$id = $row[‘id’];
$firstname = $row[‘first_name’];
$lastname = $row[‘last_name’];
$password2 = $row[‘password’];
if(password_verify($password, $password2))
{
$secret_key = "YOUR_SECRET_KEY";
$issuer_claim = "THE_ISSUER";
$audience_claim = "THE_AUDIENCE";
$issuedat_claim = TIME_IN_SECONDS; // issued at
$notbefore_claim = TIME_IN_SECONDS; //not before
$token = array(
"iss" => $issuer_claim,
"aud" => $audience_claim,
"iat" => $issuedat_claim,
"nbf" => $notbefore_claim,
"data" => array(
"id" => $id,
"firstname" => $firstname,
"lastname" => $lastname,
"email" => $email
));
http_response_code(200);
$jwt = JWT::encode($token, $secret_key);
echo json_encode(
array(
"message" => "Successful login.",
"jwt" => $jwt
));
}
else{
http_response_code(401);
echo json_encode(array("message" => "Login failed.", "password" => $password, "password2" => $password2));
}
}
?>
We now have two restful endpoints for registering and log users in. At this point, you can use a REST client like Postman to intercat with the API.
First, start your PHP server using the following command:
$ php -S 127.0.0.1:8080
A development server will be running from the 127.0.0.1:8080 address.
Let’s now, create a user in the database by sending a POST request to the api/register.php endpoint with a JSON body that contains the first_name, last_name, email and password:
You should get an 200 HTTP response with a User was successfully registered. message.
Next, you need to send a POST request to the /api/login.php endpoint with a JSON body that contains the email and password used for registering the user:
You should get a Successful login message with a JWT token.
The JWT token needs to be persisted in your browser’s local storage or cookies using JavaScript then attached to each send HTTP request to access a protected resource on your PHP server.
Protecting an API Endpoint Using JWT
Let’s now see how we can protected our server endpoints using JWT tokens. Before accessing an endpoint a JWT token is sent with every request from the client. The server needs to decode the JWT and check if it’s valid before allowing access to the endpoint.
Inside the api folder, create a protected.php file and add the following code:
<?php
include_once ‘./config/database.php’;
require "../vendor/autoload.php";
use \Firebase\JWT\JWT;
header("Access-Control-Allow-Origin: *");
header("Content-Type: application/json; charset=UTF-8");
header("Access-Control-Allow-Methods: POST");
header("Access-Control-Max-Age: 3600");
header("Access-Control-Allow-Headers: Content-Type, Access-Control-Allow-Headers, Authorization, X-Requested-With");
$secret_key = "YOUR_SECRET_KEY";
$jwt = null;
$databaseService = new DatabaseService();
$conn = $databaseService->getConnection();
$data = json_decode(file_get_contents("php://input"));
$authHeader = $_SERVER[‘HTTP_AUTHORIZATION’];
$arr = explode(" ", $authHeader);
/*echo json_encode(array(
"message" => "sd" .$arr[1]
));*/
$jwt = $arr[1];
if($jwt){
try {
$decoded = JWT::decode($jwt, $secret_key, array(‘HS256’));
// Access is granted. Add code of the operation here echo json_encode(array(
"message" => "Access granted:",
"error" => $e->getMessage()
));
}catch (Exception $e){
http_response_code(401);
echo json_encode(array(
"message" => "Access denied.",
"error" => $e->getMessage()
));
}
}
?>
You can now send a POST request with an Authorization header in the following formats:
JWT <YOUR_JWT_TOKEN_HERE> Or also using the bearer format:
Bearer <YOUR_JWT_TOKEN_HERE>

Anyone who goes through more than a couple of gallons of drinking water a day will probably be happiest with an under-sink filtration system like the Aquasana AQ-5200. If you prefer (or need) filtered water, this provides a continuous supply of it on demand from a separate tap. We recommend the Aquasana AQ-5200 because its certifications are among the best of any system we’ve found.

Westworld Welcomes Lena Waithe to Season Three

The wait is almost over for Game of Thrones fans. Come April 14, the eighth and final season of the show will finally be released and our two-year wait will finally be rewarded… probably with all the characters except Bran Stark dying because <spoilers>. There’s no doubt that it’s going to be dark, bloody, and even more incestuous than ever before. Oddly enough, Game of Thrones memes is the complete opposite of the show.

Outside the show exists a fandom of darkly humorous geeks (us). They have created their own funny fanfiction in the form of cropped photos and the impact font to make us all preoccupied while waiting for each season of the show.

How Will Game of Thrones End?

Of course, Game of Thrones is not without its innate funny moments, especially when certain characters are on-screen:

There’s also that one time The Hound laid his life down the line for some chickens:

And of course, Ser Bronn of the Blackwater, Saver of Tyrion, The Blower of the Wildfire, Walking joke encyclopedia:

Still, you’d be surprised at the creativity of some people in their Game of Thrones memes. Some of them are downright witty and most remind us why we all love the show. So, without further ado, here are some funny Game of Thrones memes– sorry, the funniest Game of Thrones memes this side of Westeros.

50. Syrio Forel A man would have been so proud…

49. What’s the difference? He died there anyway…

50 Game of Thrones Memes That Will Crack You Up

angel’o’sphere shares a report: The annual Stack Overflow survey is one of the most comprehensive snapshots of how programmers work, with this year’s poll being taken by almost 90,000 developers across the globe. This year’s survey details which languages developers enjoy using, which are associated with the best paid jobs, which are most commonly used, as well as developers’ preferred frameworks, databases, and integrated development environments. Python’s versatility continues to fuel its rise through Stack Overflow’s rankings for the "most popular" languages, which lists the languages most widely used by developers. This year’s survey finds Python to be the fastest-growing major programming language, with Python edging out Android and enterprise workhorse Java to become the fourth most commonly used language. […] More importantly for developers, this popularity overlaps with demand for the language, with Julia Silge, data scientist at Stack Overflow, saying that jobs data gathered by Stack Overflow also shows Python to be one of the most in-demand languages sought by employers. […] Rust may not have as many users as Python or JavaScript but it has earned a lot of affection from those who use it. For the fourth year running, the language tops Stack Overflow’s list of "most-loved" languages, which means the proportion of Rust developers who want to continue working with it is larger than that of any other language.[…] Go stands out as a language that is well paid, while also being sought after and where developers report high levels of job satisfaction. Full report here.
