Aggregated on: 2023-10-11 12:17:00

In a data-intensive industry like finance, data comes from numerous entries and goes to numerous exits. Such status quo can easily, and almost inevitably, lead to chaos in data analysis and management. For example, analysts from different business lines define their own financial metrics in data reports. When you pool these countless reports together in your data architecture, you will find that many metrics overlap or even contradict each other in definition. The consequence is, developing a simple data report will require lots of clarification back and forth, making the process more complicated and time-consuming than it should be. As your business grows, your data management will arrive at a point when "standardization" is needed. In terms of data engineering, that means you need a data platform where you can produce and manage all metrics. That's your architectural prerequisite to provide efficient financial services.

Bloom Filters: Efficient Data Filtering With Practical Applications

Aggregated on: 2023-10-10 02:46:59

Bloom filters are probabilistic data structures that allow for efficient testing of an element's membership in a set. They effectively filter out unwanted items from extensive data sets while maintaining a small probability of false positives. Since their invention in 1970 by Burton H. Bloom, these data structures have found applications in various fields such as databases, caching, networking, and more. In this article, we will delve into the concept of Bloom filters, their functioning, explore a contemporary real-world application, and illustrate their workings with a practical example. Understanding Bloom Filters A Bloom filter consists of an array of m bits, initially set to 0. It employs k independent hash functions, each mapping an element to one of the m positions in the array. To add an element to the filter, it is hashed using each of the k hash functions, and the corresponding positions in the array are set to 1. To verify if an element is present in the filter, the element is hashed again using the same k hash functions, and if all the corresponding positions are set to 1, the element is considered present.

Aggregated on: 2023-10-09 14:16:59

Vector search is a critical component of generative AI tooling because of how retrieval augmented generation (RAG) like FLARE helps LLMs incorporate up-to-date, customized information while avoiding hallucinations. At the same time, vector search is a feature, not a product — you need to query vectors as they relate to the rest of your data, not in isolation, and you shouldn’t need to build a pipeline to sync the rest of your data with a vector store to do that. 2023 has seen an explosion in vector search products and projects, making selecting among them a serious effort. As you research the options, you’ll need to consider the following hard problems and the different approaches to solving them. Here, I’ll walk you through these challenges and describe how DataStax tackled them for our implementation of vector search for DataStax Astra DB and Apache Cassandra.

Navigating Vector Databases and Search Through the Prism of Colors

Aggregated on: 2023-10-09 13:16:59

Vector technology in AI, often referred to with implementations, vector indexes, and vector search, offers a robust mechanism index and query through high-dimensional data entities spanning images, text, audio, and video. Their prowess becomes evident across diverse spectrums like similarity-driven searches, multi-modal retrieval, dynamic recommendation engines, and platforms leveraging the Retrieval Augmented Generation (RAG) paradigm. Due to its potential impact on a multitude of use cases, vectors have emerged as a hot topic. As one delves deeper, attempting to demystify the essence of "what precisely is vector search?", they are often greeted by a barrage of terms — AI, LLM, generative AI — to name a few. This article aims to paint a clearer picture (quite literally) by likening the concept to something we all know: colors. Infinite hues bloom,

EclipseStore: Storing More Complex Data Structures

Aggregated on: 2023-10-09 13:01:59

In the first part of my series, I showed how to prepare EclipseStore for use in a project. We also initialized the StorageManager and saved, modified, and deleted the first data. But what about more complex structures? Can you use inheritance? To do this, we will now create a small class model. First, let's look at what inheritance looks like. To do this, we take an interface called BaseInterfaceA, an implementation BaseClassA and a derivative LevelOneA. We will now try to save this and see how it behaves depending on the input when saving.

Generative AI in the Crosshairs: CISOs' Battle for Cybersecurity

Aggregated on: 2023-10-09 12:46:59

ChatGPT and large language models (LLM) are the early signs of how generative AI will shape many business processes. Security and risk management leaders, specifically CISOs, and their teams need to secure how their organization builds and consumes generative AI and navigate its impacts on cybersecurity. The level of hype, scale, and speed of adoption of Generative AI (GenAI) has raised end-user awareness of LLMs, leading to uncontrolled uses of LLM applications. It has also opened the floodgates to business experiments and a wave of AI-based startups promising unique value propositions from new LLM and GenAI applications. Many business and IT project teams have already launched GenAI initiatives or will start soon. In this article, we explore how GenAI impacts CISOs and their strategies in this evolving landscape.

Securing Your CI/CD: An OIDC Tutorial

Let's start with a story: Have you heard the news about CircleCI's breach? No, not the one where they accidentally leaked some customer credentials a few years back. This time, it's a bit more serious. It seems that some unauthorized individuals were able to gain access to CircleCI's systems, compromising the secrets stored in CircleCI. CircleCI advised users to rotate "any and all secrets" stored in CircleCI, including those stored in project environment variables or contexts.

Make Your Jobs More Robust With Automatic Safety Switches

Aggregated on: 2023-10-08 22:01:59

In this article, I'll refer to a "job" as a batch processing program, as defined in JSR 352. A job can be written in any language but is scheduled periodically to automatically process bulk data, in contrast to interactive processing (CLI or GUI) for end-users. Error handling in jobs differs significantly from interactive processing. For instance, in the latter case, backend calls might not be retried as a human can respond to errors, while jobs need robust error recovery due to their automated nature. Moreover, jobs often possess higher privileges and can potentially damage extensive data. Consider a scenario: What if a job fails due to a backend or dependency component issue? If a job is scheduled hourly and faces a major downtime just minutes before execution, what should be done?
