Another great reference on creating Gems

https://buttercms.com/blog/launching-your-own-ruby-gem-build-it/

Experimenting with the process

1. We need to start by creating the gem

bundle gem smsparatodos_client

2. Defining dependencies in smsparatodos_client.gemspec and for this one we are going to add httparty gem

In a Rack-based application, including frameworks built on top of Rack like Ruby on Rails and Sinatra, middleware plays a crucial role in processing HTTP requests and responses. When you're working within a Rack middleware, accessing request headers is straightforward because the request is represented as an environment hash (env) passed to the call method of your middleware.

Here's how to access request headers in different ways within a Rack middleware:

Using Rack::Request.new

app/middleware/user_token_authenticator_middleware.rb

class UserTokenAuthenticatorMiddleware
  def initialize(app)

Elevated email bounce rates through your Amazon SES account

In this article, I'm going to be sharing how we got notified of our elevated email bounce rates, how we made a first big reduction by enabling the suppression list functionality on AWS SES, and then how we were able to identify bounced accounts and the commands and CLI tools you can use for managing your suppression list.

It is Friday, and all of a sudden you receive an Amazon support email saying that your account has been moved under review. 😱

We placed your SES account in the US xxx (City) Region under review. You can still use this account to send emails, but you should fully address the problems that led to your account being placed under review.

So, what are the steps that we followed in order to fix this problem?

How to run examples

1. Run $ createdb uniq-db-test to create DB
2. Run example with Ruby (e.g., $ ruby 1_find_or_create_by_single_thread.rb)

Third party SAML Single Sign On (SSO) integration/implementation - Tech spec

• Author: Heriberto Perez

Background

The implementation of SSO in order to connect with other services/providers/sites is a common requirement these days

For those cases when you have the need to integrate a third party service and embed some widgets in your site, and in order to make it in a secure way and based on dynamic data for the current authenticated, that is when the SSO integration comes handy for you.

Goals

This Tech spec will serve as a reference a SAML Single Sign On (SSO) integration.

Let's start changing the repository to trigger an exception(typo in the orderby clause):

DatabaseBooksRepository.java

public class DatabaseBooksRepository implements BooksRepository {
  private final DatabaseHelper databaseHelper;
  public DatabaseBooksRepository(Content context) {
   databaseHelper = OpenHelperManager.getHelper(context, DatabaseHelper.class);
  }

heridev

Seems to be pretty simple to install so now let's start with some examples with the same BooksActivityPresenterTest

BooksActivityPresenterTest.java

import org.junit.Test;
import org.junit.Asserts;
import org.junit.runner.RunWith;
import org.mockito.junit.MockitoJUnitRunner;

Implementing the database thing

OpenHelperManager.java

/* this is not the complete example for the implementation
 but it is just a sample as I didn't write it all that
*/
public class DatabaseHelper extends OrmLiteSqliteOpenHelper {
  private static final String DATABASE_NAME="Sniptit.rb";

Created following this sets of tutorials: https://www.youtube.com/watch?v=ZWYOy8E4jWo&index=1&list=PLtRrDEpV3zkvVd3gpUS8oJDh1iPXGzDHj We start with a huge BooksActivity.java class so we are going to split it into MVP and in order to have more control when testing that.

BooksActivity.java

public class BooksActivity extends AppCompatActivity implements BooksActivityView {

    //SHORTCUTS
    //Alt + Enter (field name)
    //Alt + Insert (constructors)
