Scaling Agile Frameworks: Creating Solutions or Problems?

When the Agile Manifesto was published in 2001, it brought together several lightweight methods under one umbrella term. Agile methodologies have since been widely adopted across technology companies, as they bring effective benefits in guiding the development and delivery of high-quality, working software.

However, Agile methodologies were designed for small teams, often between five and nine members. So what happens when companies take over massive projects that require dozens or even hundreds of people working towards one common goal? How can you apply Agile methodologies to such an environment? And how do you do it while maintaining both the quality of your output and the best practices within your team?

Porting From Nashorn: How To Handle JS Multi-Threading on Graalvm

Porting existing JavaScript code from Nashorn to GraalVM can be a challenge. This article focus on a multi-threading issue we got into when we ported SwiftMQ Stream scripts generated from Flow Director.Porting from Nashhorn

Javascript Is Single-Threaded

If you register an asynchronous callback on a Java class and this callback is invoked while you are still within the execution of the same JS script, you have multi-threaded access, even if you immediately schedule the processing of the callback in an event queue. Nashorn doesn’t check this, but GraalVM does and throws an exception. So any script with such callbacks will not work on GraalVM.

11 Best Production Debugging Tips and Techniques To Speed up Bug Fixes

We understand Java Remote Debugging in Production is always a hectic process and it will take much time to get the issues fixed and stabilized. So, if you’re assigned to the maintenance team to work on fixing bugs in the production environment, we have compiled the 11 best Production Debugging Tips And techniques that will help you find issues and fix bugs much quicker than usual.

But, wait… before getting started, let’s understand what production debugging is and why production debugging is important in the development business.

gRPC for .NET: Creating a gRPC Server Application

While working with Protobuf message format for one of my client projects, I recently came across a gRPC framework. After doing my analysis, gRPC seems pretty promising for inter-service communication, particularly in microservices architectures. gRPC is a language-agnostic, high-performance Remote Procedure Call (RPC) framework. 

gRPC is built on top of the HTTP/2 transport layer and therefore can support four types of gRPC methods (unary, client streaming, server streaming, and bi-directional streaming). It uses Protobuf for message exchange.

Yolo-FastestV2: Faster and Lighter

Yolo-Fastest focuses on single-core, real-time inference performance and low CPU usage under real-time conditions. Not only can it realize real-time performance on mobile phones, but also on RK3399, Raspberry Pi 4, and various Cortex-A53 while remaining low-cost. The power consumption device meets certain real-time performance standards. After all, these embedded devices are much weaker than mobile phones, but they are more widely used and cheaper.

Let me talk about the original intention of Yolo-Fastest. Most people used Mobilenet-SSD in early lightweight object detection. In actual tests, it is difficult to achieve real-time on commonly used ARM devices; it can only be done on some high-end mobile phones. All big cores can barely reach real-time when booting, not to mention the "powerful" RK3399 and other commonly used ARM CPUs in the industry. Real-time is basically impossible.

The Green Lining in Cloud Computing

In current COVID times, the mantra for success includes a healthy mix of innovation with thoughtfulness and corporate social responsibility. As the efforts toward digital transformation are accelerating, so are the pressures to operate as responsible businesses. More and more CXOs are working on striking the right balance between accelerating digital transformation and their sustainability strategy, in addition to adopting a more digitized stand with a “cloud-first” approach.

Sustainability in the Cloud

Companies have historically driven financial, security, and agility benefits through the cloud, but sustainability is becoming imperative. According to the United Nations Global Compact-Accenture Strategy CEO Study on Sustainability, more than 99% of CEOs from large companies now agree that “sustainability issues are important to the future success of their businesses.” Two-thirds of the CEOs view the fourth industrial revolution (4IR) technologies as a critical factor for accelerating socio-economic impact. 59% of CEOs say that they are deploying low-carbon and renewable energy across their operations today.

How To Animate Data With the ArcGIS API for JavaScript

Animations can be useful to detect or visualize patterns in your data as the geometry or attributes change. Adding animations to your applications can really help bring your data to life, and allows you to see spatial patterns that you might not realize at first glance.

Animating hurricanes as they move over time

This post will walk you through how to create different kinds of animations using the ArcGIS API for JavaScript, one of several mapping APIs included with the ArcGIS Platform. While animations can be fun and can help create a sense of things happening, it’s important to remember to ask yourself: What did I just see? How did the data change as I animated it?

How to Send WordPress Emails Using Amazon SES (Step by Step)

Are you having trouble sending emails from your WordPress site?

One easy way to improve WordPress email reliability is by using the Amazon Simple Email Service, or Amazon SES.

In this article, we will show you step by step how to send emails from your WordPress site using Amazon SES.

How to Send WordPress Emails Using Amazon SES (Step by Step)

Why and When You Need Amazon SES for WordPress Emails

All too often we hear that users have trouble sending emails from their WordPress website. That’s a problem because you rely on email to keep your website running smoothly.

For example, your site relies on email to reset lost passwords, or send notifications when new users register or someone fills in your contact form.

By default, WordPress uses the PHP mail function to send out emails. However, this function doesn’t always work as expected. That’s often because WordPress hosting companies block it to prevent abuse and spam.

Also, spam filters on popular email service providers check incoming emails to verify the sender. Default WordPress emails fail this check and sometimes may not even make it to the spam folder.

SMTP (Simple Mail Transfer Protocol) is the industry standard for sending email. Unlike the PHP mail function, SMTP uses proper authentication, which increases the chances your emails will be successfully delivered.

Amazon SES is an SMTP service designed for business email. It’s a good solution for sending WordPress notification emails to just you and your team, and also sending email newsletters to large mailing lists.

The service is free for the first year. After that, you may need to pay as you go, depending on the number of emails you send and other factors. You can get an idea of what it will cost you on the Amazon SES pricing page.

In this tutorial, we’ll show you how to send email to the Amazon SES service from your WordPress website using the WP Mail SMTP plugin.

Editor’s Note: we believe that Amazon SES is a bit complicated for beginners. This is why we generally recommend users to use SMTP.com or Sendinblue which both works with WP Mail SMTP plugin as well.

Configuring Your Amazon AWS Account

First, you’ll need to sign up for a free account by visiting the Amazon Web Services website. While the account is free, you will need to enter credit card details when setting up the account.

You’ll Need to Sign Up for a Free Account with Amazon Web Services

Once you’ve created an AWS account, you’ll need to set up a User. This will provide you with access keys needed later.

To do that, you need to open the Amazon Web Services Users page. Within this page, you need to click the ‘Add users’ button.

Click the Add Users Button

Next, you need to set up a new user. In the User name field, you can add any name you’d like, but we recommend you use the format yourdomain_wpmailsmtp.

This will be helpful in the future if you create additional users for other websites. You’ll know at a glance which website each user is for, and that it’s used by the WP Mail SMTP plugin.

You Need to Set Up a New User

You will also need to select the AWS credential type. You should click the checkbox next to ‘Access key – Programmatic access’.

Once you’re finished, you can click the ‘Next: Permissions’ button at the bottom of the screen.

You’ll now see the ‘Set permissions’ screen. You need to click on the third option, ‘Attach existing policies directly’.

You’ll Now See the 'Set Permissions' Screen

Then you should type ‘AmazonSESFullAccess’ into the search bar to filter the list. Now just one policy should be listed. Make sure you click the checkbox on the left of that policy.

After that, click on the ‘Next: Tags’ button at the bottom of the screen. We don’t need to change any settings on the ‘Add tags’ page, so just click the ‘Next: Review’ button and you’ll be taken to the Review page.

Once there, you can see all of the details you’ve chosen for this user. If everything looks correct, then simply click on the ‘Create user’ button.

You Can See All of the Details You’ve Chosen for this User

You will now see a message that you successfully created the user. You will also see an Access Key ID and Secret Access Key for your user.

You’ll need these later in the tutorial, so you should make a copy of them in a safe location or simply download the CSV file. Alternatively, just keep this browser window open so you can come back to it later.

You Will Now See a Message that You Successfully Created the User

Switching Amazon Web Services to Production Mode

By default, your Amazon SES account will be run in Sandbox Mode. This limited mode will only allow you to send emails to verified email addresses and is designed to stop spammers from abusing the system.

If you want to send emails to anyone, then you’ll have to make a request to move from Sandbox Mode to Production Mode. The first step is to visit the AWS Support page for creating a new case.

First you’ll need to log in as the user you just set up. Once you’re on the ‘Create case’ page, you’ll need to click on the second option, ‘Service limit increase’.

Click on the Second Option, ‘Service Limit Increase’

Next, you will need to fill in the case details. Amazon will use your answers to make sure that you won’t be sending spam emails.

You should leave the limit type as ‘SES Service Limits’ and select ‘Transactional’ as the mail type. In the Website URL field you should type in your site’s address.

Case Details

The next section is labeled ‘Describe, in detail, how you will only send to recipients who have specifically requested your mail’. Here you should share some details about your email sending process.

For example, you could say that you are only sending site notifications to the site administrator, or sending mail only to those who have filled out a form on your site.

Case Details

Then you are asked to ‘Describe, in detail, the process that you will follow when you receive bounce and complaint notifications’. For example, you can explain that the ‘Force From Email’ setting in WP Mail SMTP will send all bounce notifications to a specified email address.

When asked whether you will comply with the AWS terms of service, you should answer ‘Yes’.

Next, you should scroll down to the Requests section. Start by selecting the same region as when you set up your AWS account. This will be the region closest to where your site’s server is located.

For the limit field, you should select ‘Desired Daily Sending Quota’ from the drop down menu. After that, under ‘New limit value’ you should type in your estimate of the maximum number of emails you expect to send in a day.

Select ‘Desired Daily Sending Quota’ From the Drop Down Menu

The last section on the page is ‘Use Case Description’. Here you should share details of the kind of website you have and why you will be sending emails.

Make sure you include the types of emails that will be sent, such as confirmations of form submissions, purchase receipts, or newsletters. A more detailed response here may give your application a greater chance of success.

Use Case Description

Once you have completed the application, go ahead and click the Submit button. You’ll get two emails from Amazon Web Services confirming that a new case has been created.

You should receive a decision from Amazon within one business day. But in the meantime, you can continue with this tutorial.

Installing WP Mail SMTP on Your WordPress Website

WP Mail SMTP is the best SMTP plugin for WordPress. You will need to buy a Pro plan or higher to use Amazon SMTP. This also gives you access to premium support and white glove set up by one of their experts.

If you’d like to have the WP Mail SMTP support team set this up for you, you can follow their guide on how to request white glove set up for SMTP instead of following the steps below.

First, you’ll need to install and activate WP Mail SMTP on your website. For more details, check out our guide on how to install a WordPress plugin.

Installing WP Mail SMTP

On activation, the WP Mail SMTP setup wizard will start automatically. You’ll need to click on the Let’s Get Started button.

WP Mail SMTP Setup Wizard

Next, you’ll be shown a list of email services that are supported. Here you need to select Amazon SES and then click on the ‘Save and Continue’ button.

Select Amazon SES

You will see a message explaining that Amazon SES is a good choice for technically advanced users. You should click the ‘I Understand, Continue’ button to dismiss the message.

After that, you’ll be asked to configure your mailer settings. You’ll need to fill in the Access Key ID, Secret Access Key, and Region fields with the information you copied earlier when you created an Amazon AWS account.

Fill in the Access Key ID, Secret Access Key, and Region Fields

Now you need to scroll down to the SES Identities section. Here you can choose to verify either your domain or email address.

Verifying Your Domain

The benefit of verifying by domain is that it will verify any email address that uses that domain. Verifying an email address is easier, but then you will have to verify every email address you wish to use separately.

To verify your domain name on Amazon SES, you need to make sure the Verify Domain option is selected. After that, you should type in the domain name you used when signing up for Amazon AWS.

Verify Your Domain Name on Amazon SES

Once you’ve entered the domain name, you need to click the Verify Domain button. You will be given a name and value to add to a new TXT record in your domain’s DNS settings.

Verify Domain TXT Record

For instructions on how to create a TXT record to your site’s DNS settings, see our DNS guide

After you have successfully verified your domain, you should return to your site’s WP Mail SMTP settings and then refresh the page. Any verified domains will now be displayed.

You can now skip the ‘Verifying Your Email’ section below and move on to ‘Setting Up the From Name and Email’.

Verifying Your Email

If you only plan on using a single email address with WP Mail SMTP, then verifying your email address is a good choice.

First, you need to click on the Verify Email Address option and then you should type the email address you plan to use in the field provided.

Verify Email Address

Once you’ve entered the email address you need to click the Verify Email button. You will see a notice asking you to check your email inbox for a confirmation email.

This email will be sent from Amazon Web Services and will include a verification link. You must click this link within 24 hours in order to verify this email address.

Check Your Email Inbox for a Confirmation Email

After you’ve successfully verified your email, you can return to your site’s WP Mail SMTP settings and refresh the page. Any verified email addresses should be displayed.

Setting Up the From Name and Email

Now you should scroll down to the final section of the page where you can enter the ‘From’ name and email address.

You need to type a name in the From Name field. This is the name associated with the emails you send and will be set to your site’s name by default.

You can change this to any name, such as your business name or personal name. You can also check the Force From Name option to apply this setting site-wide.

Type the From Name and From Email

You can enter any verified email address into the From Email field. For best results, we recommend that you use a business email address with your site’s domain such as example@yourwebsite.com.

We recommend you check the box labeled Force From Email. This means you’ll automatically use the same outgoing email address across your WordPress site.

This option will save you the trouble of editing the email settings throughout your site and makes it less likely that your emails will go to spam.

Once you’ve finished entering the settings, you can click the Save and Continue button.

Enabling WP Mail SMTP Features

Finally, you will be asked which email features you wish to enable. By default, the first three options are enabled. These are improved email deliverability, email error tracking, and a weekly email summary.

You Will Be Asked Which Email Features You Wish to Enable

If you like, you can enable detailed email logs as well. Once you have made your selection, you should click the Save and Continue button.

Entering Your WP Mail SMTP License Key

Finally, you need to enter your WP Mail SMTP license key. You were sent this key by email when you signed up for your WP Mail SMTP Pro account.

You can also find your license key by clicking ‘View License Key, Details, and Downloads’ from the Account Page on the WP Mail SMTP website.

Enter Your WP Mail SMTP License Key

Once you’ve entered your license key you should click the Verify License Key button. You should see a success message. Simply click OK to acknowledge the message and then click on the Continue button.

You Should See a Success Message

WP Mail SMTP will now check your mailer configuration. If everything is working as expected, then you’ll see a screen with the message ‘Congrats, you’ve successfully set up WP Mail SMTP!’

If there is something wrong, then you’ll see a message that says ‘Whoops, looks like things aren’t configured properly’. You will need to click the Start Troubleshooting button to fix the error.

Click the Start Troubleshooting Button

Sending a Test Email

Once you’ve finished troubleshooting, you might like to send out another test email to make sure everything is working correctly.

You’ll need to navigate to WP Mail SMTP » Tools and then click on the ‘Email Test’ tab. By default, the test email will be sent to your site’s admin email address, but you can change this. Next, click ‘Send Email’.

Send a Test Email

If everything has been set up correctly, then you should see a Success! message.

You Should See a Success! Message
