Aggregated on: 2024-09-26 20:06:19

Angular is one of the most popular frameworks for building dynamic web applications, and at its core lies RxJS, is a library designed for composing asynchronous and event-based programs by using observable sequences. RxJS operators are powerful tools that allow developers to manipulate and transform data streams efficiently. But how exactly do you use them in Angular? This article will provide a detailed, step-by-step guide on how to leverage RxJS operators in Angular, complete with examples to help you master this essential skill. What Are RxJS Operators? In Angular, RxJS operators play a key role in managing HTTP requests, user actions, and other asynchronous tasks, making it easier to chain operations and work with data streams. These operators are essentially functions that take an Observable as input and produce a new Observable as output. This allows developers to efficiently handle asynchronous workflows, event handling, and state management. RxJS operators are grouped into categories like creation, transformation, filtering, and combination, offering a powerful toolkit for composing and managing complex operations.

Building a Zero Trust API With ASP.NET Core: A Developer’s Guide

Aggregated on: 2024-09-26 01:21:19

In a world where cyber threats are just one click away (or just one QR code scan away), the old-school “castle and moat” security approach isn’t enough. Enter Zero Trust — a security model that flips the script, requiring every request to be verified, authenticated, and monitored, no matter where it comes from. For developers working with ASP.NET Core APIs that handle sensitive data, this isn’t just a trend; it’s a necessity. Let’s dive into the why, what, and how of implementing Zero Trust in your ASP.NET Core API.

Concurrency Issues in SQL and Distributed Systems

Aggregated on: 2024-09-26 00:36:19

An SQL database must handle multiple incoming connections simultaneously to maintain optimal system performance. The expectation is that the database can accept and process numerous requests in parallel. It's straightforward when different requests target separate data, such as one request reading from Table 1 and another from Table 2. However, complications arise when multiple requests involve reading from and writing to the same table. How do we keep the performance high and yet avoid consistency issues? Let’s read on to understand how things work in SQL databases and distributed systems. Transactions and Issues An SQL transaction is a collection of queries (such as SELECT, INSERT, UPDATE, DELETE) sent to the database to be executed as a single unit of work. This means that either all queries in the transaction must be executed, or none should be. Executing transactions is not atomic and takes time. For example, a single UPDATE statement might modify multiple rows, and the database system needs time to update each row. During this update process, another transaction might start and attempt to read the modified rows. This raises the question: should the other transaction read the new values of the rows (even if not all rows are updated yet), the old values of the rows (even if some rows have been updated), or should it wait? What happens if the first transaction must be canceled later for any reason? How should this affect the other transaction?

Probabilistic Graphical Models: A Gentle Introduction

Aggregated on: 2024-09-25 17:21:19

What Are Probabilistic Graphical Models (PGMs)? Probabilistic models represent complex systems by defining a joint probability distribution over multiple random variables, effectively capturing the uncertainty and dependencies within the system. However, as the number of variables increases, the joint distribution grows exponentially, making it computationally infeasible to handle directly. Probabilistic Graphical Models (PGMs) address this challenge by leveraging the conditional independence properties among variables and representing them using graph structures. These graphs allow for a more compact representation of the joint distribution, enabling the use of efficient graph-based algorithms for both learning and inference. This approach significantly reduces computational complexity, making PGMs a powerful tool for modeling complex, high-dimensional systems. PGMs are extensively used in diverse domains such as medical diagnosis, natural language processing, causal inference, computer vision, and the development of digital twins. These fields require precise modeling of systems with many interacting variables, where uncertainty plays a significant role [1-3].

Efficient Transformer Attention for GenAI

Aggregated on: 2024-09-24 18:21:18

Generative AI (aka GenAI) is transforming the world with a plethora of applications including chatbots, code generation, and synthesis of images and videos. What started with ChatGPT soon led to many more products like Sora, Gemini, and Meta-AI. All these fabulous applications of GenAI are built using very large transformer-based models that are run on large GPU servers. But as the focus now shifts towards personalized privacy-focused Gen-AI (e.g., Apple Intelligence), researchers are trying to build more efficient transformers for mobile and edge deployment. Transformer-based models have become state of the art in almost all applications of natural language processing (NLP), computer vision, audio processing, and speech synthesis. The key to the transformer's ability to learn long-range dependencies and develop a global understanding is the multi-head self-attention block. However, this block also turns out to be the most computationally expensive one, as it has quadratic complexity in both time and space. Thus, in order to build more efficient transformers, researchers are primarily focusing on:

Human Introspection With Machine Intelligence

Aggregated on: 2024-09-24 13:21:18

Computational logic manifests in various forms, much like other types of logic. In this paper, my focus will be on the abductive logic programming (ALP) approach within computational logic. I will argue that the ALP agent framework, which integrates ALP into an agent’s operational cycle, represents a compelling model for both explanatory and prescriptive reasoning. As an explanatory model, it encompasses production systems as a specific example; as a prescriptive model, it not only includes classical logic but also aligns with traditional decision theory. The ALP agent framework’s dual nature, encompassing both intuitive and deliberative reasoning, categorizes it as a dual-process theory. Dual-process theories, similar to other theoretical constructs, come in various versions. One such version, as Kahneman and Frederick [2002] describe, is where intuitive thinking “swiftly generates instinctive solutions to judgment issues,” while deliberative thinking “assesses these solutions, deciding whether to endorse, adjust, or reject them.”

Not that it was completely smooth sailing; not when the company had to shelve "Sky" due to its striking similarities to Scarlett Johansson.

Reducing Infrastructure Misconfigurations With IaC Security

Aggregated on: 2024-09-23 20:21:18

Infrastructure as Code (IaC) became the de facto standard for managing infrastructure resources for many organizations. According to Markets and Markets, a B2B research firm, the IaC market share is poised to reach USD 2.3 Billion by 2027. What Is Infrastructure as Code? Before IaC, a developer would use the cloud provider GUI, clicking through different configurations and settings to provision a resource like a Virtual Machine. When you need to provision a single instance, this is easy, but modern workloads are more than one single machine, 1000s of VMs, and hundreds of storages — not to forget this is for one region. To achieve high availability, the same stamp needs to be created in multiple regions and availability zones. One way organizations automated this process is, through scripts, though it had challenges like versioning and, most importantly, the redundancy of each team repeatedly creating scripts from scratch.

No front-end build step: no TypeScript, no minification, etc. All dependencies are managed from the backend app, i.e., Maven It's important to note that the technology I'll be detailing, except Vaadin, follows a similar approach. Vaadin, with its unique paradigm, really stands out among the approaches.

Enhancing Few-Shot Text Classification With Noisy Channel Language Model Prompting

Aggregated on: 2024-09-18 22:21:15

Few-shot learning is a fascinating area in natural language processing (NLP), where models are trained to perform tasks with very few labeled examples. Traditional approaches often rely on directly modeling the conditional probability of a label given an input text. However, these methods can be unstable, especially when dealing with imbalanced data or the need for generalization to unseen labels. A recent advancement in this area is the noisy channel language model prompting, which takes inspiration from classic noisy channel models in machine translation to improve few-shot text classification. Here are two concrete examples of problems in few-shot learning that the noisy channel language model prompting aims to solve:

Aggregated on: 2024-09-18 20:21:15

The rising demand for sustainable and eco-friendly computing solutions has given rise to the area of green computing. According to Wikipedia, Green computing, green IT (Information Technology), or ICT sustainability, is the study and practice of environmentally sustainable computing or IT. With the rise of cloud computing in the last few decades, green computing has become a big focus in the design and architecture of software systems in the cloud. This focus on optimizing the resources for energy efficiency allows us to focus on cost optimization in addition to reducing the carbon footprint. AWS is one of the cloud providers leading the movement from the front. AWS is investing heavily in renewable energy and designing its data centers with efficiency in mind. According to the Amazon Climate Pledge, Amazon aims to achieve net-zero carbon emissions by 2040 and has already made significant strides, including powering its operations with 100% renewable energy by 2025. Additionally, AWS provides tools like the AWS Carbon Footprint Calculator, enabling customers to monitor and reduce their carbon emissions, thereby fostering a more sustainable digital ecosystem.

This article offers an approach to writing integration tests for Kafka-based applications that focuses on interaction specification, making tests more readable and easier to maintain. The proposed method not only enhances testing efficiency but also contributes to a better understanding of the integration processes within the application. The article builds on three ideas presented in relevant articles: writing tests with a clear separation of Arrange-Act-Assert stages, isolation in Kafka tests, and using tools to enhance test visibility. I recommend reviewing these before delving into the material of this article.
