Web2 Was Built Using JavaScript, and Web3 Should Be Too

Aggregated on: 2022-11-21 21:28:49

We have heard a lot about Web3 over the last few months, however, there is still an element of mystery as to what it is and how we can operate on it. The latest market downturn in the crypto industry has led to further scepticism among both users and developers but we must separate the infrastructure of Web3 from the volatility that can erupt from the crypto market. By focusing on building and improving the underlying foundation of Web3, we will begin to uncover the true potential of this technology. To do so, we first need to encourage more developers to take part in this new era of the web. JavaScript is the key to accomplishing this. If we think about the inception of the internet as we know it, we were faced with the same scepticism then as we are now. However, with the help of developers who both believed in the technology and had the tools at hand to help craft our current online experience, we have seen the widespread adoption of Web2. But why stop there? Why not continue to grow alongside continuously expanding and emerging technologies?

Understanding Consistency Level in the Milvus Vector Database (Part II)

Aggregated on: 2022-11-21 21:28:49

In the previous blog about consistency, we have explained what the connotation of consistency in a distributed vector database is, covered the four levels of consistency - strong, bounded staleness, session, and eventually supported in the Milvus vector database, and explained the best-suited application scenario of each consistency level. To offer a quick recap, consistency in a distributed database specifically refers to the property that ensures every node or replica has the same view of data when writing or reading data at a given time. Therefore, the word consistency we talk about in this blog stands for the letter "C" in the CAP theorem.

Decision Trees in Machine Learning Modern machine learning algorithms are revolutionizing our daily lives. For instance, large language models like BERT are powering Google Search, and GPT-3 is powering many advanced language applications. Today, building complex machine learning algorithms is easier than ever. However, no matter how complex a machine learning algorithms get, it falls under one of the following learning categories:

Posture Recognition: Natural Interaction Brought to Life

Aggregated on: 2022-11-21 21:28:49

Augmented reality (AR) provides immersive interactions by blending real and virtual worlds, making human-machine interactions more interesting and convenient than ever. A common application of AR involves placing a virtual object in a real environment, where the user is free to control or interact with the virtual object. However, there is so much more AR can do beyond that. To make interactions easier and more immersive, many mobile app developers now allow users to control their devices without having to touch the screen by identifying the body motions, hand gestures, and facial expressions of users in real time and using the identified information to trigger different events in the app. For example, in an AR somatosensory game, players can trigger an action by striking a pose, which spares them from frequently tapping keys on the control console. Likewise, when shooting an image or short video, the user can apply special effects to the image or video by striking specific poses without even having to touch the screen. In a trainer-guided health and fitness app, the system powered by AR can identify the user's real-time postures to determine whether they are doing the exercise correctly and guide them to exercise in the correct way. All of these would be impossible without AR.

The Distributed Data Problem

Aggregated on: 2022-11-21 21:28:49

Today, online retailers sell millions of products and services to customers all around the world. This was more prevalent in 2020, as COVID-19 restrictions all but eliminated visits to brick-and-mortar stores and in-person transactions. Of course, consumers still needed to purchase food, clothing, and other essentials, and, as a result, worldwide digital sales channels rose to the tune of $4.2 trillion, up $900 billion from just a year prior. Was it enough for those retailers to have robust websites and mobile apps to keep their customers from shopping with competitors? Unfortunately, not. Looking across the eCommerce landscape of 2020, there were clear winners and losers. But what was the deciding factor?

How to Avoid Risks Before Implementing Industrial IoT Solutions

Aggregated on: 2022-11-21 21:28:49

If you are wondering about the implementation of Enterprise IoT solutions, you understand that this process is rapidly developing all over the globe. Accoring to McKinsey Digital, 127 devices hooked up to the Internet for the first time every second in 2021, and in North America alone the worth of smart factories is expected to reach $500 billion in 2022. This trend is not surprising, as EIoT implementation helps to achieve a level of worker safety that was unattainable before, as well as new business models, and, therefore, new revenue flows. Using IoT devices, you will be able to get more information about manufacturing processes, employee and client behavior, and data that will help predict breakdowns and prevent downtime of equipment. Sounds tempting? All these benefits are achievable, but they depend on the company's ability to correctly assess the risks of EIoT implementation.

Why Is Testing So Important in Frontend?

Aggregated on: 2022-11-21 21:28:49

According to Uncle Bob, tests are part of the system; many developers think the opposite since they are not deployed. He declares that it is a catastrophic point of view since the test’s role is to support the development and keep the system robust and easy to change. (Clean Architecture, Robert C. Martin, 2018) In Frontend, it is commonly tested, the interactions of the end users with our application. We should guarantee to our users when they log in, open a pop-up, add a comment or do any other interaction with our apps to not encounter any errors and live undesirable experiences.

Why Kubernetes Observability Is Essential for Your Organization

Aggregated on: 2022-11-21 21:28:49

The Kubernetes service simplifies load balancing and container management of containerized applications. Simply put, it makes it easier for enterprise applications to have greater scalability, flexibility, and portability. After Linux, Kubernetes is one of the fastest-growing projects in the history of open-source software. According to a study by CNFC, the number of Kubernetes engineers grew by 67% to 3.9 million. It is a go-to solution for cloud orchestration in distributed environments. But, cloud architecture has become complicated, and organizations find it challenging to fix the bugs. When developers need to address the root cause, they encounter a lack of observability due to non-tracking of the state of Kubernetes, serverless functions, and other aspects of cloud architecture. This lack of visibility into what’s going on led to the need for Kubernetes Observability.

What Should You Avoid When Doing DevOps?

Aggregated on: 2022-11-21 21:28:49

The goal of the DevOps practice is an enabling technology that allows developers (Dev) and operations teams (Ops) members to work together more efficiently by automating deployment processes — all while keeping the customers' data safe. But along this journey, companies face many common challenges and traps when implementing these principles, which we'll explore here. The DevOps Team The central idea behind DevOps is that there should be more collaboration and shared ownership between existing teams. Companies often struggle with adopting these practices because they create new silos and do not bring different groups closer together. This makes sense only when you think how much more efficiently something can be accomplished if everyone works towards achieving shared goals rather than having separate teams doing their own thing without any communication whatsoever.

Spring Modulith: Have We Reached Modularity Maturity?

Aggregated on: 2022-11-21 21:28:49

One of the main reasons to design microservices is that they enforce strong module boundaries. However, the cons of microservices are so huge that it's like chopping off your right hand to learn to write with the left one; there are more manageable (and less painful!) ways to achieve the same result. Even since the microservices craze started, some cooler heads have prevailed. In particular, Oliver Drotbohm, a developer on the Spring framework, has been a long-time proponent of the moduliths alternative. The idea is to keep a monolith but design it around modules.

Write Your Kubernetes Infrastructure as Go Code - Combine CDK8s With AWS CDK

In an earlier blog post you saw how to use cdk8s with AWS Controllers for Kubernetes (also known as ACK), thanks to the fact that you can import existing Kubernetes Custom Resource Definitions using cdk8s! This made it possible to deploy DynamoDB along with a client application, by using cdk8s and Kubernetes. But, what if you continue using AWS CDK for AWS infrastructure and harness the power cdk8s (and cdk8s-plus!) to define Kubernetes resources using regular code? Thanks to the native integration between the AWS EKS module and cdk8s, you can have the best of both worlds!

A paradigm where open-source software and tooling enable others to contribute to projects they find valuable, while the projects offer transparency by publicly hosting their codebases. Another Web3 initiative is providing on-chain proof of contributions—the ability to prove that you can do the things you say you’ve done. One company that embodies these Web3 principles is Truffle. Not only is most of its tooling open source so anyone can contribute, but they also provide POAPs for those who do.

When Not To Use a Graph Database

Aggregated on: 2022-11-21 21:28:49

The use of graph databases has grown massively in recent years, and they are becoming promising solutions for organizations in any industry. Their increased flexibility makes it easier to leverage relationships and connections in a way that traditional relational databases can't do. But how do you know when to use a graph database? In this article, we explore what to consider if you’re thinking of using a graph database and show how the best approach may be to not use one at all. What Is a Graph Database? A graph database is a type of database that uses graph theory as the foundation for its data model. Graph databases consider connectedness as a first-class citizen, making them better suited to represent connected data than more old-school relational databases.

Why Are Devs Still Talking to DevOps?!

Aggregated on: 2022-11-21 21:28:49

DevOps got off to a promising start. Way back in 2006, Amazon CTO Werner Vogel prophesied a hassle-free relationship between development and operations: “The traditional model is that you take your software to the wall that separates development and operations and throw it over and then forget about it. Not at Amazon. You build it, you run it. This brings developers into contact with the day-to-day operation of their software.” This you-build-it-you-run-it movement, which became known as DevOps, got us all excited over the promise that it would destroy silos and get teams working together more efficiently than ever before.

However, historically, a great deal of testing has been guesswork. We create user journeys, estimate load and think time, run tests, and compare the current result with the baseline. If we don't spot regressions, the build gets a thumbs up, and we move on. If there is a regression, back it goes. Most times, we already know the output even though it needs to be better defined — less ambiguous with clear boundaries of where a regression falls. Here is where machine learning (ML) systems and predictive analytics enter: to end ambiguity.

Auto-Scaling a Spring Boot Native App With Nomad

Aggregated on: 2022-11-21 20:28:49

Horizontal scaling and in particular auto-scaling is a common challenge for many applications no matter their architectural approach (monolithic or microservices) and the deployment environment (cloud or on-premises). Today's Cloud providers provide a rich variety of options and tools to accommodate this critical requirement: to be able to scale services instances up or down, based on specified rules, in an efficient manner in order to: Avoid unavailability Ensure the quality of service Optimize resources utilization Avoid unnecessary charges Many of the out-of-the-box solutions rely on Kubernetes and offer various levels of abstraction to make this process as smooth as possible. However, there are many cases where we don't really need or cannot afford all these cloud offerings as-a-service or we need to operate our own data centre on-premises. As presented in a previous article "Look, Ma! No Pods!", HashiCorp Nomad is a simple and flexible deployment tool, able to manage both containers and non-containerized applications running on-prem, cloud or hybrid environments. Lately, Nomad provides auto-scaling functionality via the Nomad Autoscaler Agent. As described in the Nomad Autoscaler Overview, the following strategies are supported:

When To Use the @DynamicUpdate With Spring Data JPA

Aggregated on: 2022-11-21 17:13:49

The Spring Data JpaRepository interface comes with the save(S entity) method that is frequently used to update an entity representation on the database level. By default, the method generates an UPDATE statement that requests a change to the values of all the entity class columns. This includes the columns not touched by your application code. However, this behavior can be far from satisfactory for several reasons. Luckily, Hibernate supports the @DynamicUpdate annotation that, once applied to an entity class, helps the save(S entity) and similar methods generate a SQL update command with columns that are actually changed.
