How to Run Parallel Cypress Tests on BitBucket Pipeline

Posted: 30 Apr 2021 05:29 PM PDT

Do you use BitBucket Pipeline as your CI server? Are you struggling with slow E2E tests in Cypress? Did you know BitBucket Pipeline can run parallel steps? You can use it to distribute your browser tests across several parallel steps to execute end-to-end Cypress tests in a short amount of time.

How to Run Tests in Parallel

Distributing tests across parallel steps to spread the workload and run tests faster might be more challenging than you think. The question is how to divide Cypress test files across the parallel jobs in order to ensure the work is distributed evenly? But… is distributing work evenly what you actually want?

Detecting Viruses in Real-Time at Scale

Posted: 30 Apr 2021 03:00 PM PDT

Cybersecurity remains a persistent threat to both individuals and businesses, with data privacy concerns increasing for 86% of companies in 2020 and just 23% of consumers believing their personal data is very secure. As malware becomes steadily more omnipresent and sophisticated, a proactive approach to threat detection has become essential. Trend Micro is a global leader in hybrid cloud security, network defense, small business security, and endpoint security. To protect Android devices from viruses, the company built Trend Micro Mobile Security — a mobile app that compares APKs (Android Application Package) from the Google Play Store to a database of known malware. The virus detection system works as follows:

  • External APKs (Android application package) from the Google Play Store are crawled.
  • Known malware is converted into vectors and stored in Milvus.
  • New APKs are also converted into vectors, then compared to the malware database using similarity search.
  • If an APK vector is similar to any of the malware vectors, the app provides users with detailed information about the virus and its threat level.

To work, the system has to perform a highly efficient similarity search on massive vector datasets in real-time. Initially, Trend Micro used MySQL. However, as its business expanded so did the number of APKs with nefarious code stored in its database. The company's algorithm team began searching for alternative vector similarity search solutions after quickly outgrowing MySQL.

Setting up MongoDB Cluster and Replica-Set

Posted: 30 Apr 2021 02:31 PM PDT

Database Replication

Database replication is a process in which we run a set of database instances that maintain the same datasets and it provides redundancy and promises high availability of database servers. In case your one database falls down then you still will be able to use the other available database from the cluster and have the same datasets that you had in your previous replica. 

In this post, I am going to demonstrate the replication setup in MongoDB. If you're using some other database you might need to check if your database supports replication or not.

How to Generate and Compare Perceptual Image Hashes in Java

Posted: 30 Apr 2021 01:12 PM PDT

Perceptual image hashing is a relatively new process used primarily in the multimedia industry for content identification and authentication. The process itself uses an algorithm to extract specific features from an image and calculate a hash value based on that information. The hash value that is generated acts as a kind of 'fingerprint' for the image; it is a distinct identifier that is unique to its parent image. 

As you may have guessed by the fingerprint comparison, perceptual image hashing is particularly useful for digital forensics, but it has become an important player in prohibiting online copyright infringement as well. By comparing the hash value of an original/authentic image with the hash value of a similar image, you can identify and match various images and calculate the Hamming Distance between them. For reference, Hamming Distance measures the minimum number of substitutions it takes to change one image to the other, so hash values that are closer together are more similar. 

Top IoT App Development Trends in 2021

Posted: 30 Apr 2021 11:35 AM PDT

More Focus on Container Technologies in IoT Platforms

Gartner projects that over 75% of global organizations will be using containerized apps in production by 2022. So far, container technologies have been part of traditional enterprise IT environments and cloud architectures. Recent developments in industrial IoT platforms and the increased demand for vendor-neutral IoT technologies, however, have made containers increasingly relevant for the Internet of Things. 

Defining Containers

What is a container? It is a lightweight virtualization technology that includes an entire runtime environment. This means an application and all its dependencies, plus the libraries and configuration files required to run the application. Container technologies help you abstract differences in operating systems and underlying infrastructures. This is why they are often embedded in IoT platforms so that you can connect to any device and make virtually any machine or piece of legacy equipment IoT-ready. 

Top 10 Key Elements for Successful SAFe Implementation

Posted: 30 Apr 2021 11:19 AM PDT

The Scaled Agile Framework® (SAFe®) came into being to help modern enterprises implement Lean-Agile development at scale more effectively and smoothly. So, if an enterprise wants to implement this framework to reap the maximum benefits of the Lean-Agile Development at scale, it is essential for it to absorb Lean-Agile culture, Lean-Agile mindset, and Lean-Agile principles at the personal, intellectual, and leadership levels. This thorough absorption at all these levels forms the base on which SAFe can be implemented effectively.  

The successful SAFe implementation consists of these factors:

How to Maintain a Healthy Codebase While Shipping Fast

Posted: 30 Apr 2021 10:09 AM PDT

One of my greatest privileges building Stepsize has been hearing from hundreds of the best engineering teams in the world about how they ship software at pace while maintaining a healthy codebase.

That's right, these teams go faster because they manage technical debt properly. We're so used to the quality vs. cost trade-off that this statement sounds like a lie—you can't both be fast and maintain a healthy codebase.

5 Customer Data Integration Best Practices

Posted: 30 Apr 2021 10:03 AM PDT

For the last few years, you have heard the terms "data integration" and "data management" dozens of times. Your business may already invest in these practices, but are you benefitting from this data gathering? 

Too often, companies hire specialists, collect data from many sources and analyze it for no clear purpose. And without a clear purpose, all your efforts are in vain. You can take in more customer information than all your competitors and still fail to make practical use of it.  

The Engineer’s Complete Guide to Technical Debt

Securing the Future of Remote Working With Augmented Intelligence

Posted: 30 Apr 2021 09:32 AM PDT

Introduction

Are you familiar with the fact that utilization of artificial intelligence across businesses will tend to create $2.9 trillion of business value in 2021 as well as 6.2 billion hours of productivity? Keeping in view this up-pacing technology, the artificial intelligence market is projected to grow to $190 billion by the year 2025. 

Without any uncertainty, it is clear this whole globe is accommodated with synergizing human intelligence and artificial intelligence. The immense acquisition is observed especially during the pandemic of COVID-19 which was an excuse that "work from home" is becoming a new normal. Either working from home, or from the office or a blend of both, employees are learning to work in different ways with different collaborative tools. As organizations are facing this new normal, technological advancements have made work from home a seamless reality. The evolution of augmented intelligence has paved the way for collaborative experience and richer work.

Resolving Data Theft in IoT Networks To Grow Your Business

Posted: 30 Apr 2021 09:10 AM PDT

Introduction

IoT is flawed. If a smart, imaginative team built the service, there's a smarter and more imaginative attacker waiting for you. Whatever appears Smart may also be fully vulnerable to serious threats. When more untested devices join an IoT network, it gets increasingly complicated to track potential blind spots leaving the system open for cybercriminals. 

98% of all IoT traffic is NOT encrypted, making it the lowest hanging fruit for attacks. In all honesty, attackers have been innovative in using the existing issues in the devices and sneak in. So be it secretly extracting information from internal networks or launching direct infrared laser attacks on devices, it is safe to believe that IoT is not safe.

Important Uses of Mobile App Performance Testing Tools

Posted: 30 Apr 2021 08:55 AM PDT

Introduction

Mobile app performance testing is carried out to assess the performance of applications under real-world conditions. The end goal is to predict the user's experience after the public release of the application. For testers working with mobile app performance testing tools, performance assessment usually means running multiple parallel tests to measure the system's response for critical user journeys across a wide range of devices, locations, and networks. Performance testing also assesses the app's response during periods of high traffic load and ensures its stability. 

As such, the following are some of the use cases of mobile app performance testing tools for a mobile app tester.

Anypoint VPC Connection Tutorial

Posted: 30 Apr 2021 08:31 AM PDT

Anypoint VPC

Many developers, consultants, or architects are fronted by challenging architecture designs where particular security, availability, and/or network restrictions must be considered while designing integration solutions.

Anypoint Platform, among its components, provides the Anypoint VPC: an AWS VPC (virtual private cloud) in the requested AWS region, assigned exclusively to its owning Anypoint Platform organization where only authorized users from the organization may deploy Mule applications to this Anypoint VPC [1]. Paraphrasing the above text, a VPC is a private IP space that is dedicated to the Mule workers. Is not accessible by any other systems in your network and no other company might share it. For more details about AWS VPC refer to this link.

Security and Compliance Considerations for Using Salesforce

Posted: 30 Apr 2021 08:07 AM PDT

Introduction

Many MNC's (Multinational companies) use Salesforce as their main tool of option for CRM (Customer Relationship Management) in the cloud. Also, it aims at providing a lot of flexibility and comfort while enabling or granting access to the data and that too from any device and working from any given location.

The most important point to note here is that the Salesforce platform has very high-security standards, but there have been few recent changes in global data protection regulations. This has further imposed limitations in many countries around the world.

Infrastructure as Code Pitfalls and How To Avoid Them

Posted: 30 Apr 2021 07:38 AM PDT

Introduction

Infrastructure as Code. It's not a totally new concept, but it isn't something that everyone is doing at this point. Some have been doing it for a long time. Some have just started the journey. And some have no clue what it even is. We're going to break it down a bit today, and talk about what it is and some of the common issues, or pitfalls, that come along with it.

What Kind of Pitfalls Can Come Up?

I have great news for you... The answer is "a lot." It's not very good news, I guess. But as long as you take the time to consider all your options, and plan accordingly, you can mitigate just about any issues that come up. So, why is there a lot that can go wrong? It's because of the nature of Infrastructure as Code. It's infrastructure and it's code. That means you take all the pitfalls that can come along with infrastructure and add them to all the pitfalls that can come along with code. 

Adopting a Multi-Cloud Strategy

Posted: 30 Apr 2021 07:19 AM PDT

Introduction

You must have heard the famous English proverb, "Don't put all your eggs in one basket." I know you might be thinking, "What exactly does multi-cloud have to do with eggs?" Let me explain.

Open-source technology has enabled us to mix and match cloud environments from different vendors, empowering companies to get products & services to market faster while meeting unique requirements. The uptake of multi-cloud architecture is growing as organizations are seeing the value of expanding their cloud platform portfolio as the fastest way to serve their customers.
