Search engines look simple from the outside: you type a query and get results. Building one is really a sequence of practical systems—data collection, text processing, indexing, ranking, and serving—stitched together with careful engineering. This article walks through the major steps and design choices for creating a working search engine, from a basic prototype to something you can grow over time.

How Do You Build a Search Engine?

Stock trading is full of patterns, noise, and time pressure. That mix makes it a strong match for AI: machines that can learn from data, react quickly, and follow rules without fatigue. Programming AI into trading is not a single trick—it’s a workflow that turns market data into decisions, then turns decisions into controlled orders.

Can AI Be Programmed Into Stock Trading?

Most LLM products with “browse” or “online” modes hide their web search stack behind proprietary infrastructure. The core idea is simple: the LLM doesn’t “browse” the web by itself. Instead, it calls a tool you define—typically named something like web_search—and your backend handles the actual HTTP requests and data cleaning.

How do I ask an AI to web search for me?

Auto-suggest (or Typeahead) is arguably one of the most high-pressure components in a search stack. While the UI feels simple, the backend is a distributed system constrained by strict latency requirements. It must ingest petabytes of log data, index it, and serve predictions in under 100 milliseconds to keep up with a user’s typing speed.

Under the Hood: The Architecture of Search Auto-Completion

Snow cleanup in front of the house can feel endless, especially when the plow leaves a heavy ridge just as you finish. A few smart habits, the right tools, and good timing can cut the work down and keep walkways safer.

How do you clean snow fast?

Searching through a codebase can feel slow when you rely only on your editor’s global search. `grep` gives you a direct, script-friendly way to find patterns across files and folders from the terminal. It’s quick, flexible, and works well for everything from spotting function calls to hunting down configuration values.

How do I search code with grep?

Modern software builds are automated pipelines that scan code, transform files, connect dependencies, and produce deployable output. When something goes wrong, the build system halts and reports errors collected during those steps. A familiar example is running npm run build, which often ends with a clear “Failed to compile” message when the toolchain encounters blocking issues.

How Software Builds Detect and Report Compilation Failures

Light-based transmitters are the workhorses of fiber-optic communication. They take electrical data from a device and convert it into carefully controlled flashes of light that can travel long distances through optical fiber with low loss and low interference. This article explains the main stages of that conversion, from bits to photons, and what must go right for the link to perform well.

How Does a Transmitter Turn Data Into Light?

QR codes look like simple black-and-white squares, yet they carry structured data that a camera can decode in a fraction of a second. When you point your phone at a QR code, the camera captures an image and software interprets the pattern into text, a URL, Wi‑Fi credentials, payment details, or other data. The process can feel “visual,” but it is mostly computational pattern recognition rather than human-like visual cognition.

How does a QR code work?

Fiber optic cable carries data as light rather than electrical signals. That simple change is why fiber can move enormous amounts of information over long distances with low loss and high reliability. Instead of pushing electrons through metal, fiber guides pulses of light through a thin strand of glass or plastic, keeping the signal clean and stable even across many kilometers.

How does fiber optic cable work?

Finding the right rows in a database is mostly about asking clear questions and translating them into precise queries. This article explains practical ways to search for specific data, from simple filters to joins and indexing, so your results are accurate and your queries stay quick.

How do I find specific data in a database?

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. They began as chips for drawing pixels, then grew into engines for scientific computing, machine learning, and simulation. This article explains how a GPU chip works and why it can run so many calculations in parallel.

How does a GPU work?

Web scrapers are tools that collect information from websites and turn it into structured data you can store, search, or analyze. They can be as simple as a short script that reads one page, or as complex as a system that crawls thousands of pages, handles logins, and tracks updates over time.

Embeddable chat widgets—live chat bubbles, AI assistants, and support bots—are ubiquitous on modern websites. Providers deliver a simple <script> tag that clients insert into their HTML for instant integration. Yet this ease comes with a technical hurdle: the widget must perform cross-origin API calls from the client's domain to the provider's servers, which runs afoul of the browser's same-origin policy and frequently triggers CORS errors.

Wildcard CORS Why Chat Widgets Rely on It

As cloud computing has grown, so has the need to work with massive amounts of data stored outside traditional file systems. Services like Azure Blob Storage, Amazon S3, and Google Cloud Storage are designed to store enormous volumes of unstructured data—images, videos, logs, backups, and datasets. While these platforms are powerful and scalable, they’re accessed through APIs rather than normal folders. This is where blob mounting comes in. Blob mounting bridges the gap between object storage and everyday file-based workflows by making cloud blobs appear as if they were part of your local filesystem.

What Is Blob Mounting? Making Cloud Storage Feel Like a Local Folder

Programmers often need to search through piles of text: log files, source code, configuration files, and command output. Doing that manually is slow and error-prone. The `grep` command solves this problem by scanning text and printing the lines that match a pattern. It’s one of the most practical tools you can learn if you work on Unix-like systems such as Linux and macOS, and it’s widely available in development environments.

What Is the grep Command?

If you’re learning web development, you’ve probably come across the term “traversing in JavaScript.” But what does traversing actually mean? Traversing in JavaScript means moving through elements or data structures step by step in order to access, read, or manipulate them. It’s most commonly used when working with the **DOM (Document Object Model), but it also applies to **arrays, objects, and tree-like structures.

What Does “Traversing” Mean in JavaScript?

Have you ever written a perfectly reasonable line of JavaScript like 0.1 + 0.2 and gotten back 0.30000000000000004? It feels almost mocking—how can a language built for the modern web fail at such basic math? The truth is, JavaScript isn’t bad at math at all. It’s extremely precise. The surprise comes from what kind of math it’s doing. Under the hood, JavaScript uses the same binary floating-point system found in most programming languages and even tools like Excel. And that system, while powerful, was never designed to represent everyday decimal numbers cleanly.

Why JavaScript Has Floating-Point Precision Issues (and How to Fix Them)

An algorithm engineer in a large technology company spends most of their time doing grounded, practical work: reading logs, debugging visualizations, writing small, targeted code changes, and running controlled experiments to see whether those changes actually improve system behavior.

Chip design relies on a large set of specialized software tools, usually grouped under the term EDA (Electronic Design Automation). These tools help engineers turn an idea—like a CPU, GPU, modem, or power controller—into manufacturable layouts made of millions to billions of transistors. Because chip creation spans many steps, no single program does everything; teams combine tools for design entry, verification, physical implementation, and signoff.

What Software Do Engineers Actually Use to Design Modern Chips?

Printed circuit boards (PCBs) are the physical platforms that hold and connect electronic parts. They appear in everyday products like phones, cars, medical devices, appliances, and industrial machines. Without PCBs, most electronics would be bulkier, less reliable, and harder to manufacture consistently.

LLM training data is the fuel for your AI engine, and the quality of that fuel determines whether your model is a hallucinating jalopy or a high-performance reasoning machine. In 2025 and 2026, the landscape has shifted from scraping everything to curating the best. Here is a guide on where to find the high-quality data needed to train your own LLMs today.

What Are Top LLM Data Sources for 2026

When you scan a scratched CD, download a file over a weak signal, or read a QR code with part of it missing, something remarkable often happens: the data still comes back perfectly.One of the main reasons this works is a technique called Reed–Solomon error correction. Reed–Solomon (RS) codes don’t just detect errors. They are designed to reconstruct lost information, even when entire chunks are wrong or missing.

What Is Reed–Solomon Error Correction?

People often say “the database is down” or “install the database,” which can make the term sound like a single thing. In practice, “database” can mean different parts of a data system. Whether a database is software depends on which meaning you are using.

Is a Database a Type of Software?

Apple has confirmed a multi‑year agreement with Google to use Gemini AI models as a foundation for a revamped Siri and broader Apple Intelligence features expected later in 2026. The partnership positions Gemini as a deep, system-level capability rather than a simple add‑on chatbot integration.

LangChain is an open-source framework built to support applications that use large language models in structured, reliable ways. It focuses on turning raw model outputs into systems that can search data, use tools, and follow multi-step logic. Language models are powerful on their own, but real products rarely rely on a single prompt and a single answer. Most useful systems need memory, access to files or databases, and the ability to perform actions such as calculations or API calls. LangChain was created to organize those needs into a clear development framework.

What Is LangChain?

In the high-stakes race for artificial intelligence dominance, the finish line keeps moving. Just as the world began to acclimate to the power of NVIDIA’s Blackwell chips, the tech giant has once again reset the standard. At CES 2026, NVIDIA unveiled its latest marvel: the Vera Rubin platform. Named after the pioneering astronomer who provided the first evidence of dark matter, this new system is not merely a faster chip—it is a re-imagining of the AI Supercomputer designed to power a new generation of autonomous, reasoning AI.

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.
