Turning a PDF into high-quality embedding chunks is less about “cutting it small” and more about producing chunks that are coherent, searchable, and stable over time. A good pipeline keeps meaning intact, preserves useful structure, and produces consistent text that won’t shift every time you reprocess the same file.

How Do You Engineer High-Quality PDF Embedding Chunks?

Electric cars turn electrical energy into motion with fewer moving parts than a gasoline vehicle. Instead of burning fuel to create power, an EV stores electricity in a battery and uses electronics and a motor to drive the wheels. The result is smooth acceleration, quiet operation, and a drivetrain built around energy flow rather than combustion.

How Does an Electric Car Work?

AI can create and edit PowerPoint (PPT) files by turning plain text, notes, or documents into structured slide decks, then refining design, layout, and wording with consistent formatting. It works through a mix of language processing (to plan the story) and design automation (to shape visuals). Below is a practical look at what AI can do, how the workflow typically runs, and what to watch for when you want a usable presentation rather than a rough draft.

Can AI Create and Edit a PPT File?

Retrieval-Augmented Generation (RAG) helps a language model answer with facts drawn from your own documents. Instead of relying only on what the model “knows,” it retrieves relevant text passages and then writes a response grounded in them. The key question is how it selects the right passages from a large collection during a conversation.

How does RAG find the right context?

Large language models (LLMs) can write, reason, code, and chat in a way that feels close to human thought. Yet their “thinking” is not a stream of conscious ideas. It is a structured statistical process that turns text into numbers, runs those numbers through many layers of computation, and then produces the next token in a sequence.

How Do LLMs “Think”?

Counting sounds simple: ask for a number, get a number. In databases, counting can range from instant to painfully slow depending on what you count, how data is stored, and what the engine must scan to answer the query.

How do databases count rows?

Large language models (LLMs) often look like they “know” what they’re doing: they write clean functions, follow frameworks, and even fix bugs. What’s really happening is next-word prediction carried to an extreme scale, trained on vast amounts of text that includes a lot of code and technical discussion.

How does an LLM predict the next word in programming?

Graphics processing units, or GPUs, handle vast amounts of math at the same time.

LangChain is an open-source framework for building applications powered by large language models (LLMs). It helps developers go beyond simple prompts and turn language models into systems that can use data, tools, memory, and multi-step workflows. Instead of treating an LLM as a standalone chatbot, LangChain provides the structure needed to integrate it with real-world software components like databases, files, and APIs.

What Is LangChain? A Practical Introduction

Large language models (LLMs) are often described as “just weights.” That phrase sounds dismissive, but it’s accurate in a technical sense: the model’s learned behavior is stored in a huge collection of numbers. When you ask an LLM a question, those numbers guide how it turns your text into a response.

What Do LLM Weights Do?

When you hear about a new smartphone with a 3nm chip or a laptop powered by 5nm technology, these numbers refer to the manufacturing process used to create the processor. The nanometer measurement describes the size of transistors packed onto the silicon wafer, with smaller numbers indicating more advanced technology.

What Does 3nm or 5nm Mean in Chips?

A new year is a practical moment to upgrade how you work. AI tools are no longer “nice to have” for a few technical teams—they’re becoming standard work companions for writing, analysis, planning, and operations. Learning how to work with AI now is less about chasing trends and more about gaining a reliable edge in output quality, speed, and clarity.

Using a Virtual Private Network (VPN) is a common way to enhance online privacy and security. Many users wonder what data gets sent to their Internet Service Provider (ISP) when they connect through a VPN. This article explains the types of traffic transmitted during VPN use and how it affects what your ISP can see.

What Traffic Do You Send to Your ISP When Using a VPN?

During the holiday season, many families unwrap a smart speaker for the first time—often placing it in the kitchen or living room alongside decorations, music, and gatherings. Almost immediately, one question comes up around the table: Is this thing always listening? Understanding how wake-up words work can help answer that question and put new users at ease.

How Wake-Up Words Work on an AI Speaker

Large language models (LLMs) run on text, but they don’t “see” text as letters. They operate on vectors: long lists of numbers that represent meaning, context, and relationships in a form that math can handle. This article explains what those vectors look like, where they appear inside an LLM, and why they matter.

What Do Vectors Look Like in LLMs?

When managing your domain through modern DNS providers like Cloudflare, you often encounter a critical choice for each DNS record: Proxied versus DNS Only. Frequently represented by visual toggles like an orange or grey cloud, this setting fundamentally changes how visitors connect to your website and services. Understanding this distinction is key to securing your infrastructure.

Is Your Server’s IP Address Exposed? Understanding DNS Proxying

A Canonical Name (CNAME) record is a DNS entry that maps an alias name to a true or canonical domain name. Instead of pointing a domain directly to an IP address, a CNAME points to another domain name, which eventually resolves to an IP address. This structure functions like a nickname or a forwarding address, ensuring that if the IP address of the main domain changes, all aliases automatically update without needing manual reconfiguration.

What Is a CNAME in DNS?

Artificial intelligence often appears to be a solitary genius, capable of absorbing information independently and spitting out wisdom. This perception misses the vast industrial effort occurring behind the scenes. Models do not simply absorb knowledge from the web; they are spoon-fed by teams of people who decide exactly what information is worthy of consumption. The sophistication of modern algorithms relies heavily on old-fashioned human editorial judgment to create the pre-training datasets that power these systems.

Why Human Experts Play the Vital Role in AI Pretraining

Semantic search is transforming how search engines understand user queries and retrieve relevant information.

Creating a large language model (LLM) requires several key steps, with pre-training being a fundamental phase. This stage establishes the foundation upon which the model learns language patterns, vocabulary, and contextual understanding. Here is a closer look at what the pre-training process involves and why it is critical in developing effective LLMs.

What Is the Pre-Training Stage in Creating a New Large Language Model?

Keeping accounts secure requires more than just a strong password. Even the most complex phrases can be stolen through phishing attacks or data breaches. This challenge led to the creation of two-factor authentication (2FA), and one of the most reliable forms of 2FA is the Time-based One-time Password (TOTP). TOTP provides a frequently changing, temporary code that acts as a second lock on your sensitive accounts, making it vastly harder for unauthorized people to gain access.

What Are Time-Based One-Time Passwords (TOTP)?

In recent years, data cleaning has gained recognition not just as an IT chore but as an independent business opportunity. As organizations rely heavily on data for decision-making, machine learning, and artificial intelligence, the importance of high-quality, accurate data has skyrocketed. This shift is creating a new niche in the business world, where specialized services and tools focus solely on preparing data for analysis and training models.

Why Is Data Cleaning Becoming a New Type of Business?

Semantic search is transforming the way people find information online and within systems.
