Attend the Great WP Virtual Summit for Free: August 19-23

For five days next week, from August 19-23, the inaugural event of The Great WP Virtual Summit will be taking place.

Conceived by South African based WordPress developer Anchen le Roux, the summit aims to bring together experts from various fields within the WordPress ecosystem to share their knowledge over the five days

I reached out to Le Roux, to find out why she came up with the idea of the summit, and what her goals are for the event.

“Being an organiser of WordCamp Johannesburg for the last few years, I’ve been very aware of how only a small number of people are actually able to attend an event like WordCamp. 

Obviously there are a lot of reasons, but for the most part travelling, accommodation, and other logistical items seemed to be the biggest hindrance.”

Being based at the tip of Africa, Le Roux also realized that many other African countries don’t even have a WordCamp, and started wondering what she could do to bring WordCamp to them. The idea for the summit was born.

“I’m hoping an online summit can introduce aspects of WordPress, and being part of the WordPress community, to those living in areas where it’s not easily accessible. It’s also my hope that this will plant a seed with folks, to start their own local communities around WordPress, and ultimately lead to more local WordCamps.”

Anchen is hoping to recreate some of the atmosphere and energy that takes place at a local WordCamp, at this online event.

“I know nothing can substitute for the in-person experience of a WordCamp but I’m trusting that some bits of what makes WordCamps awesome can be recreated in what we do. I’m hoping for this to be the first of many. This first one is very much an experiment but I’m anticipating for it to grow into something that more people can be involved in.“

I asked Le Roux what she hopes attendees will take away from the event.

“Firstly, the goal is to allow folks to learn from top authorities in the WordPress realm on a variety of topics. We have four different tracks catering to all types of  WordPress users. Topics range from branding and design, development, and running your business with WordPress, to running a WordPress agency or being a WP freelancer. 

Above and beyond that, I’m hoping that folks who are new to the community, or are operating on the fringes of our community, are encouraged to become a bigger part of the WordPress community, by giving them the opportunity to chat with other community members, ask questions and/or share ideas.

We have 20+ experts over 5 days, who will teach you strategies you can use to both improve and scale your WordPress business, no matter which stage you’re at, or what type of user you are.”

The Great WP Virtual Summit is happening August 19 – 23 and you can get your free tickets to the event right now by visiting the tickets page.

The Top 13 WordPress Page Builders Compared (2019)

Say you’re planning to bake a pizza. What will the base, sauce, cheese, and toppings be? Thin or thick crust? Marinara or pesto sauce? Mozzarella, cheddar or Parmesan cheese? Pepperoni, mushrooms, anchovies? And let’s not even talk about pineapple here!

There are so many variations to choose from. If only there was a way to mix and match them to get exactly what you want. Oh wait…there are several food chains who’ve exploited this very need.

If you’re planning to customize your WordPress website, using a page builder is similar to customizing a pizza. You choose the elements you want in your page, add content, set their alignment, background, colors, fonts, etc. And voila! Your page is ready to be published, for the entire world to savor.

What is a WordPress Page Builder?

In WordPress, a page builder is essentially a plugin that lets you design your site’s pages and posts without any coding involved. It’s a given nowadays for most page builders to come with drag-and-drop functionality. Thus, you can create detailed web page layouts pretty fast, like building a complex structure out of legos.

Why Use a Page Builder for WordPress?

There are many advantages of using a page builder. Here are the 4 primary ones:

No Coding Knowledge Required

Many website owners find it difficult to make even minor changes to their website’s page layouts or styles. You may know exactly what you want to change, but may not know how. With a page builder, you don’t need to learn HTML, CSS, JavaScript, or PHP to make these changes.

This enables you to achieve high-end web pages without any coding involved. What would’ve taken days or weeks earlier, including hiring a professional web developer, can now be done by yourself in a matter of hours, if not minutes.

Feature-Rich

Another amazing advantage of page builders is that they come loaded with tons of on-page widgets and features: Sliders, image carousels, galleries, content grids, social sharing buttons, pricing tables, charts, CTA buttons, forms, animations, etc.

Want the same functionalities without using a page builder? You’d have to install quite a few dedicated plugins, premium or otherwise. First, you’d need to research to find the right plugins. Then, you’d have to learn how to use them. And after that, you’ll have to make sure that they’re all up-to-date and work perfectly with one another and all the other plugins you’ve installed.

Imagine doing that with half a dozen plugins, or even more. A page builder eliminates that hassle and helps you keep it simple.

Pre-Built, Attractive Templates

Most page builders come with beautifully crafted templates for standard website pages such as Home, About, Services, Products, Contact, etc. These templates are a great way to kickstart your designing process.

Some page builders also allow you to mix and match sections from multiple templates, thereby giving you virtually unlimited page design options to choose from.

Easy Customizations

Page builders are fast and intuitive. With user-friendly features such as drag-and-drop support and a live preview mode, you can add modules to your pages easily, and then rearrange and resize them quickly as you like. You can also change their styles such as background, font, color, padding, margin, and border effortlessly.

Any changes you make will be reflected immediately in the live preview section, helping you fine-tune your site.

With so many page builders for WordPress out there, we decided to compare the top ones and list them all, so that you can decide which will be the right fit for you.

Let’s begin!

Beaver Builder

Beaver Builder markets itself as “a complete design system.” It’s a flexible drag-and-drop page builder that works on the front-end of your WordPress website, so you can see the changes live as you’re making them. You can also click on individual elements to edit their properties.

If you’re new to page builders, Beaver Builder also includes an intuitive onboarding tour that will explain all its features one by one, helping you get familiarized with its user-friendly interface.

There are modules for adding almost any element you may want on a page, including content sliders, maps, testimonials, galleries, slideshows, accordions, pricing tables, etc.

And if you want to get a headstart with your designing process, it also includes more than 50 finely-crafted templates for landing and content pages. They’re all mobile-friendly, responsive layouts. You can even save your custom templates for use in other sections of your website, or on a different website altogether (all WordPress developers say yay!).

Beaver Builder plugin works great with almost every WordPress theme and Gutenberg. And if you want to uninstall it for any reason, it doesn’t leave behind a mess. If you’re a WordPress developer or an agency, you’ll appreciate how Beaver Builder can help you build some flexibility into your workflow.

Take Beaver Builder for a spin here and see for yourself whether it’s the right fit for you. There’s also a lite version of the plugin available for free on WordPress.org repo (with limited features though).

Pricing: Starts at $99/year (Unlimited Sites) / Lite Version Is Free

Elementor

Elementor is another front-end focused page builder plugin for WordPress. It prides itself on its fast live design and inline editing capabilities. And deliver it does, which probably accounts for its 3 million+ active installations!

With Elementor, you make changes to the page and instantly see exactly how it looks like. It makes the whole process of designing and editing web pages a seamless experience. Elementor also works perfectly fine with or without Gutenberg.

While the free version of Elementor plugin includes over 100 designer-made templates and just 30 basic widgets, the Pro version takes it to a whole new level with 300+ pre-built templates and 50+ advanced widgets.

Elementor Pro also tacks on a theme builder, a popup builder, a visual form builder with popular marketing integrations, WooCommerce builder with 15+ shop widgets, dynamic content & custom fields capabilities, and motion effects.

It’s certainly one of the most ambitious page builders for WordPress out there.

Since Elementor is released under Open Source and GPL, other developers are free to create their own extensions for it. Check out these amazing add-ons for Elementor on WordPress.org repo.

Elementor Pro pairs well with free themes such as Hello Elementor, Astra, OceanWP and GeneratePress.

Pricing: Starts at $49/year (1 Site) / Free (Only 30 Basic Widgets)

Divi

Divi labels itself as “the ultimate WordPress theme and visual page builder.” Its visual page builder has a pretty slick, easy-to-use interface and comes loaded with tons of features out of the box.

While the Divi Builder plugin works best with the Divi All-in-One theme, you can also pair it up any theme of your liking. It works just fine. And just like Beaver Builder and Elementor, Divi Builder employs a front-end, drag-and-drop WYSIWYG (what you see is what you get) editor.

It comes with 40+ website elements and 800+ pre-made designs, including 100+ full-website packs. Furthermore, Elegant Themes adds brand new layouts to Divi Builder almost every week. All these features come together to help you create amazing designs with surprising ease.

When it comes to pricing, Divi has the sweetest deal of all the premium page builder options out there. Not only does it come with a great theme and the standalone page builder plugin, it also includes all the other products by Elegant Themes.

Try the Divi Builder Demo and see it in action for yourself.

Pricing: Starts at $89/year (Unlimited Sites), $249 for lifetime access

Visual Composer Website Builder

Visual Composer Website Builder is a drag-and-drop solution to create websites you’ve always wanted. Just like the options mentioned above, it sports a live front-end editor, which allows you to make changes to your website instantly and see how it looks before hitting the publish button.

It comes with 200+ premium templates and content elements, enabling you to design spectacular landing pages or page sections in minutes. To give you an idea of its extensive customization options, just its button element comes in 30 unique styles.

While Visual Composer sports a clean and minimalistic interface, its actual user experience leaves much to be desired. It does need some getting used to, but once you’ve figured it out, it’s a breeze from there on.

Unlike with other page builder plugins listed above, it also lets you edit the header, footer, sidebar, and other theme features. This is why it’s called a website builder, rather than a page builder.

Visual Composer Website Builder is made by the same team behind WPBakery Page Builder plugin, which confusingly enough was named Visual Composer before. They had to rebrand their old product to avoid trademark restrictions set by Envato marketplace. In case you were confused about this, now you know!

Pricing: Starts at $59/year (1 Site), $349/year (Unlimited Sites)

WPBakery Page Builder

WPBakery is both a front-end and back-end page builder plugin for WordPress. Its front-end user interface is quite similar to that of Visual Composer Website Builder, which isn’t surprising as it’s made by the same team.

Some users prefer its old-school back-end editor to the new front-end ones. You can also move back and forth between the two editing interfaces as needed.

It includes 50+ premium content elements, 100+ pre-built layouts, 200+ 3rd party add-ons, 40+ grid design templates, and much more. And it works with any theme, making it a comprehensive page builder solution.

However, you should note that WPBakery is a shortcode-based plugin, which means that all your customizations through it are tied to clunky shortcodes. It can slow down your website considerably if not used smartly.

WPBakery originally started its journey on Enavato’s marketplace CodeCanyon, where it’s still available. It’s also the most sold WordPress plugin on there. If you’ve ever bought a premium theme from ThemeForest, chances are high that it came preloaded with WPBakery Page Builder plugin.

Pricing: Starts at $45 (1 Site)

Oxygen

Oxygen is the new kid on the block of WordPress website builders. It’s designed from the ground up to be a full site builder, as opposed to being just a page builder. Oxygen’s templating engine lets you design every part of your WordPress site – headers, footers, pages, any post type, and any taxonomy.

With Oxygen, you’re essentially building a custom WordPress theme from scratch (though the team behind it doesn’t like to call it as such). But instead of hand-coding it, you’re using an intuitive, live visual editor to do it. This makes the process much simpler and quicker.

The elements in Oxygen are “more flexible, more customizable, and more powerful.” In a way, it lets you do more, but with less! It sounds counter-intuitive, but that’s how I can describe Oxygen in a nutshell.

The Oxygen design library includes premade design layouts for almost everything you can imagine. You can import complete websites from it with just a single click. Not happy with the existing designs? You can mix and match sections from any website template to create beautiful pages with a uniform style.

The end result is an optimized WordPress website with minimal bloat, thus making it load faster.

With that being said, Oxygen is meant for advanced, professional website designers. You need to have at least some knowledge of HTML/CSS/JavaScript, and a rudimentary understanding of PHP and WordPress CMS to make the most out of it.

The best part about Oxygen though is its current pricing, which seems almost too good to be true.

Pricing: $99/lifetime for Unlimited Sites (limited-time introductory pricing)

SiteOrigin Page Builder

SiteOrigin Page Builder boasts almost 2.5 million downloads and 1+ million active installs on WordPress.org repo. While its user interface isn’t that easy to use, it’s nonetheless a highly popular page builder plugin. This can be attributed mostly to its price (which is free), while still delivering full-fledged page builder features.

It works with any theme, supports live editing, row and widget styles, and is available in 17 languages. Page Builder uses standard WordPress widgets as its content elements, so combined with its widgets add-on bundle (also free), it should take care of most of your page designing needs.

One cool aspect of this plugin is its History Browser feature, which lets you roll forward and back easily through any changes you make. This gives you the freedom to experiment with your page layouts and designs without worrying about breaking the content.

While I wouldn’t recommend SiteOrigin Page Builder to anyone, especially newbies, it still needs to be acknowledged as it’s used by many out there.

Pricing: Free / Premium Add-ons start from $29/year (1 Site)

Themify Builder

Themify Builder is both a front-end and back-end page builder plugin for WordPress.It is included with all Themify themes as part of the Themify framework, but the standalone Themify Builder plugin works with all WordPress themes and is available for free.

Its compact back-end interface lets you to drag-and-drop modules around quickly and easily, while the front-end interface allows you to preview your design live (WYSIWYG).

Themify Builder comes with 40+ professional pre-designed layouts for various website types such as blogs, shops, portfolio, services, etc. All of these website templates can be imported with just a single click.

Most of the standard modules are included for free (text, post, gallery, video, widget, menu, slider, button, map, icons, etc.). However, you can extend its capabilities further by purchasing an add-on bundle which includes 25 extra premium modules.

If you’re looking for a free page builder for WordPress with a simple, easy-to-use interface, you should give Themify Builder a try.

Pricing: Core Plugin is Free / $39 for Add-on Bundle

Themeum WP Page Builder

Themeum is known for its high-quality, user-friendly themes, and their WP Page Builder plugin is no different. Its sleek and simple front-end interface is easy to understand, even if you’ve never used any page builders before.

WP Page Builder calls its modules add-ons, and they’re all unique and perform a specific task. As of now, it includes 30+ add-ons, with more slated to be coming soon. All your WordPress widgets can also be used as an add-on. Apart from that, you have plenty of pre-designed blocks and page layouts to choose from to get started.

Its library feature lets you save any part of your page design as its own template, which you can replicate on other pages or websites easily with just a single click. You can also import or export entire page layouts.

The free version of the plugin includes everything you need to get started. The Pro package gets you 15+ premium layout bundles, that also includes 83+ readymade page layouts. And if you ever want to create custom add-ons or add custom blocks and layouts to WP Page Builder, you can do that easily by following their developer guidelines.

Pricing: Core Plugin is Free / Pro starts at $39/year (1 Site)

Thrive Architect

Thrive Architect is an intuitive drag-and-drop front-end page builder for WordPress. What sets it apart from the rest of the page builders is that it’s focused on building landing pages that convert.

Thrive Architect comes bundled with 300+ beautifully designed landing page templates that are 100% focused on conversion.

Pricing: $67 (1 Site), $19/month (25 Sites)

GP Premium by GeneratePress

GeneratePress is one of the most popular and well-reviewed free WordPress themes. It’s built with a focus on speed and user-friendliness. And thanks to its strict adherence to WordPress coding standards, it works well with all major page builders, including Beaver Builder and Elementor.

Now, you might be wondering why a free WordPress theme is included here. Well, that’s because GeneratePress also offers a premium package called, well, GP Premium.

GP Premium builds on GeneratePress theme and adds 14 premium modules, including the Site Library, from which you can import entire demo sites with just a click. Its Sections premium module acts as a tiny page builder, allowing you to build complex web page layouts with a basic back-end interface.

While it’s not the most intuitive page builder solution mentioned here, it still needs a mention due to its performance advantage.

Most page builders add considerable bloat to your site’s frontend, but GP Premium retains its fast and lightweight nature, thereby giving your site a boost in page load speed and performance.

Pricing: $49.95/year (Unlimited Sites)

MotoPress Content Editor

MotoPress Content Editor is a drag-and-drop page builder plugin for WordPress that’ll help you create better websites with any theme. With its front-end editor, you can easily design your site’s posts, pages, or custom post types.

It includes 30+ content modules and various styling options for you to choose from. However, if you want to display videos, Google Maps, pricing tables, or add a simple contact form, you need to purchase those add-ons separately.

Try MotoPress Content Editor here and see for yourself whether it’s the right fit for you.

Pricing: Core Plugin is Free / Premium Add-ons Available

Brizy

Brizy is a relatively new entrant to the WordPress page builder plugins scene. Built from scratch and focused on usability, its intuitive and clutter-free interface ensures that you only see what’s needed for the task at hand.

Like Elementor, Brizy is an ambitious venture and has set its goals pretty high. The first thing you’ll notice about Brizy is its modern, minimalistic design.

It works pretty much like any other front-end page builder plugin for WordPress. You set your page layout, and add or remove page elements as needed. But the area where Brizy truly sets itself apart is how you customize on-page elements. This is where it shines.

For example, if you’re using Beaver Builder or Elementor, you’ll be doing it via a sidebar or a popup. But Brizy lets you edit the element properties inline, right where it is, which seems more intuitive and natural.

Another area where Brizy trumps other page builders is its cloud save feature. You don’t have to worry about saving your changes anymore. It’s all taken care of automatically. And if you ever want to roll back any changes, you can do it easily.

Brizy works with all WordPress themes.

Pricing: Starts at $49/year (3 Sites) / Lite Version is Free

Working With Custom Policy in Mule 4

MuleSoft Custom Policies can be layered on top of the implementation of the APIs to provide the governance, security, and visibility required. While the out-of-the-box API management policies cover the majority of use cases, an organization may need to create a custom policy to meet specific business needs.

There is a lot of documentation that shows how to work with MuleSoft custom policies through API manager, however, developing the custom policy and debugging them locally has been always challenging. In this article, I will demonstrate how to develop and test Mule custom policy on your local standalone Mule runtime instances before uploading to the API manager or Exchange for live running APIs.

Using Junction or Associative Tables in Entity Framework Core

When I first encountered Entity Framework (EF), I always gravitated towards a database-first option. Back when Entity Framework appeared, there wasn't a code-first option.

My thinking towards this approach was your database holds the data. If your database wasn't designed properly from the start, and you generate your entities based on the database design, your code (entities) may suffer.

Using AI and Street View to Manage Road Infrastructure

Predictive maintenance is an increasingly common sight in industrial facilities around the world, but the ability for AI to detect when machinery is about to fail relies upon a steady stream of data. One would imagine the data provided by Google Street View might not be up to the job therefore, but new research from RMIT suggests otherwise.

The authors propose using data from Google Street View to spot when road furniture needs replacing. The authors highlight the often manual and laborious task of monitoring street furniture and traffic infrastructure.

Facebook Announces Marketing API Updates Aimed at Reducing Discrimination

In March of 2019, Facebook announced changes to the company’s advertising platform, these changes aim to reduce discrimination in job postings, housing ads, and credit ads. These updates were a result of settlement agreements with several civil rights organizations that were claiming the social media giant should provide stronger protections against abuse of the Facebook advertising platform.

Automattic Acquires Zero BS CRM, Considers Rebranding it as Jetpack CRM

Automattic has acquired Zero BS CRM, a free plugin with more than 30 commercial extensions that provide deeper integrations with third-party services. Zero BS was co-founded by a two-person team that includes Mike Stott and Woody Hayday. The team marketed the plugin as a “no-nonsense CRM” and have been operating it with a successful subscription-based model for bundles of extensions.

With just 1,000 active installs on WordPress.org, Zero BS was not previously a very well-known plugin but it caught Automattic’s attention based on the strength of the product.

“Automattic reached out to us after being a happy customer,” Stott said. Former Automattic executive John Maeda had used Zero BS CRM and recommended it to the company. Stott said the main appeal for the acquisition was “strong advocacy of the product.”

It started with a support ticket Zero BS CRM received from a user, asking about Mail Campaigns and how best to set up sequences for customers.

“What we didn’t realize was this user was linked to Automattic, and was becoming a strong advocate for our product within the company,” Stott said. “What followed was a series of conversations with leaders from different parts of Automattic.”

Talks regarding the deal began in February and carried on at WordCamp Europe 2019 in Berlin.

Jetpack CRM is a Strong Consideration for Rebranding

Zero BS CRM will be rebranded as the team comes under the Automattic umbrella. The original name was somewhat polarizing in that potential customers either loved it or hated it.

Although the product’s founders have built extensions that connect WooCommerce stores to a CRM, Stott said the acquisition was not driven by Zero BS’s potential use with WooCommerce specifically.

“Variants will fit in well to Woo, Jetpack, as well as serving the standalone market,” Stott said. “If our users outgrow us, we will want to help them find the next step (similar to the Basecamp model).”

Yahoo Finance is reporting that Automattic will be rebranding the product as “Jetpack CRM,” but Stott said that has not been confirmed yet. He said Jetpack CRM is “the favorite so far internally but still open to discussion.” This may be a strong indication of what Automattic intends to do with the product.

Stott said they are not looking to compete against the likes of Salesforce or Hubspot but rather are focused on providing the basic concepts of a CRM – “knowing who your customers are, getting leads, and helping businesses grow.”

The Entrepreneur bundle is Zero BS’s most popular pricing plan, which includes all of the extensions and priority support for $17 per month, billed yearly. It accounts for approximately 75% of the company’s ARR. Stott said they do not have plans to stop the subscription model and will continue with their current pricing.

“We had planned to increase the price with v3.0 because with the updates and mail campaigns we felt we weren’t charging enough for the product,” Stott said. “But we’ve also found a good price point and Automattic didn’t want to change what was already working price wise.”

Next on the roadmap the team plans one of their most requested features: smart inbox linked to CRM data. They are aiming to release version 3.0 in September.

“I’m excited to reach more customers and just keep on building to help people and SMBs achieve the best they can,” Stott said.

Comparison Between Flutter vs. React Native for Mobile App Development

Just a few years back, we saw that mobile apps were being developed in Java using Android Studio. However, after Google launched Kotlin, not much attention was paid to framework development. Now, developers have started to create new frameworks for mobile app development like Flutter and React Native, as these frameworks make the app programming easier and bring the cross-platform features to enable development across various domains. 

Basic Comparison

If you want to include dynamic features in your app, then go with the React Native framework because it supports more third-party libraries than Flutter.

Query Languages That Can Handle ShadowDOM

XPath is a query language that is widely used by developers and QA automation engineers. Very often, XPath becomes the main engine for querying DOM nodes inside Selenium projects. Its ability to walk up or down to apply different filters and functions makes it a solid choice.

10 Free Courses to Learn Python in 2019

In recent years, I have seen more people learn Python than any other language. Many of them are learning Python to explore Data Science and Machine learning libraries provided by Python. Some people are also learning Python for web development, and there are still many developers who are learning Python for scripting and automating trivial tasks. It doesn't matter why you are learning Python at this moment; it's a great thing in itself that you have decided to learn Python.

Even though I am a Java programmer, and I have spent all my career coding in Java, I value Python very for its versatility.

Arm Twisting Apache NiFi

Introduction

Apache NiFi, is a software project from Apache Software Foundation, designed to automate the flow of data between software systems.

Early this year, I created a generic, meta-data driven data offloading framework using Talend. While championing that tool, many accounts raised concerns regarding the Talend license. While some were apprehensive of the additional cost, many others questioned the tool itself, due to the fact that their account already had licenses for other competitive ETL tools like DataStage and Informatica (to name a few). A few accounts also wanted to know if the same concept of offloading could be made available using NiFi. Therefore, it was most logical to explore NiFi.

The Significance and Challenges of Integrating Security Testing Into DevOps Pipelines

Many businesses have already embraced DevOps methodology; development and operations teams work hand-in-hand to deliver quality and enable faster time to market. The other major advantage of DevOps is Continuous Integration and Continuous Development (CI/CD), wherein processes are more agile and deploy code more quickly. It further allows teams to have the latest update on the status of their development efforts and ensure they deliver value to customers. DevOps principles and practices ensure businesses continue to stay ahead of their competition by delivering new features faster than with any other software development methodology on the go.

The fundamental facet of DevOps revolves around CI/CD pipelines for software builds:

Issues with AppSec

To understand the current and future state of application security, we obtained insights from five IT executives. We asked them, “What are the most common issues you see with application security?” Here’s what they told us: 

  • Two issues are the human attention span and the accuracy of automated systems. People who monitor or engage with security need to focus time and effort on things that matter and produce outcomes that serve a purpose. They cannot do that without accuracy, and accuracy comes from application-insight. The other is automation systems, where simply sending data is not helpful. Data must be relevant, with enough metadata to properly act. This relevance is tied to the application's insight.
  • There are so many guidelines right now. Authenticity, authorization, encryption, and availability mechanism – ensure all four are done with discipline and automation. Do the fundamentals well on APIs and mobile and modern web to avoid the majority of data breaches. When security hooks up with DevOps, it’s an impedance mismatch that causes a lot of friction.
  • The most common issue I see is doing nothing to secure your applications, followed closely by taking too narrow an approach to application security (for example, looking at security from only one perspective, such as static code analysis) and falling prey to a false sense of security. I don’t have the data to identify which is the largest actual risk based on break-ins, but I wouldn’t be surprised if the latter point is more critical.
  • We commonly see applications that are designed with security principles in mind but not from a network perspective. How an application acts on a single node in a network is different from how it behaves as it traverses the LAN and WAN. Our solution helps customers keep applications secure as they traverse networks, both local and wide-area.
  • Don’t use tools. AppSec testing technology today can come as a tool or a cloud service. Technology emerges first as a tool you learn to use, run, and be responsible for its accuracy and breadth. The next wave is when the technology is delivered as a cloud service. Now, we have more services than tools. Adopt technologies like cloud services rather than tools. Delegate AppSec to third-party vendors operating at high scale in the cloud.

How to Customize Serialization in Java Using the Externalizable Interface

In a previous article, Everything You Need to Know About Java Serialization Explained, I explained how we can serialize/deserialize one object using the Serializable interface and explain how we can customize the serialization process using writeObject and readObject methods.

Disadvantages of Java Serialization Process

But these customizations are not sufficient because the JVM has full control of the serialization process and those customization logics are just additions to the default serialization process. We still have to use the default serialization logic by calling ObjectOutputStream.defaultWriteObject() and ObjectInputStream.defaultReadObject() from writeObject and readObject methods. And if we do not call these default methods, our object will not be serialized/deserialized.
