How to Implement Linked List Data Structure
A linked list is an ordered linear data structure where elements are not stored in sequential memory locations, instead they are stored in nodes that are linked together by a pointers. Linked list are used in data intensive application because linked list offer specific benefits for high frequency data manipulation, this benefits include: Efficient insertion and deletion Adding and removing elements from a linked list is highly efficient, unlike arrays which requires shifting all subsequent elements to maintain indexing. A linked list only requires updating the pointer. Dynamic sizing: linked list can grow or shrink during runtime without needing to pre-allocate memory. Memory management: Nodes in a linked list are only allocated when needed which prevents memory wastage. Flexible Traversal: Doubly and circular list allow you to move forward or backward, which makes them helpful for complex navigation The first node in a linked list is called the head which signifies the start of the list, while the last node is called the tail and has a pointer of null except in a circular linked list. Each node in a linked list has two things which are: the actual data the pointer or reference There are three main types of linked list: Singly linked list Doubly linked list Circular linked list Singly Linked List: Singly linked list are lists where each node has a next pointer that points to the next node. Doubly Linked List: Doubly linked list are list where each node has a next and previous pointer that points to the previous and next node. Circular Linked List: Circular linked list are list where the last node points back to the first node, forming a circle. Table of Contents create node class create linked list class isEmpty and getSize Methods prepend and append Method removeHead and removeTail Methods insert and search Methods getIndex and removeIndex Methods clear and print Methods create node class First let's open our code editor and create a new file called singlyLinkedLi

I Built an Autonomous AI Agent with Google ADK + Gemini 2.0 Flash That Spots Trends and Drafts Dev.to Articles for Me
Keeping up with trending technical topics and new tools on developer forums can be time-consuming. To save time, I wanted to automate the process of finding popular articles, reading the comments to understand community sentiment, and drafting a summary. While I could write a standard Python script to scrape the dev.to API, simple scripts tend to be brittle. If an article doesn't have comments yet, a basic script will likely crash unless you write extensive error-handling logic. Instead of a rigid script, I built an Agent —a program that can dynamically reason about errors and adjust its approach. If one task fails, it can figure out the next best step. In this tutorial, I'll show you how to build a Trend-Spotting Agent using Python, the Google Agent Development Kit (ADK) , and Gemini 2.5 Flash. What We're Building We are going to write a Python application that acts as an autonomous agent. We'll give it three abilities: Search the dev.to API for rising technical articles based on specific tags. Dynamically fetch the top comments of those articles to read real community sentiment. Automatically draft a newsletter-style article on your DEV.to account summarizing its findings. Prerequisites Python 3.9+ installed on your machine. Google ADK . (Check out the Google ADK Docs if you need help installing). A DEV API Key . Grab this from your DEV.to account settings under "Extensions" and throw it in a .env file. Step 1: Giving the Agent its "Hands" (API Tools) Large Language Models (LLMs) are incredibly smart, but out of the box, they can't actually do anything on your computer. The coolest part about Google ADK is that we can write standard Python functions, hand them to the LLM as "tools", and let the AI decide how and when to use them. Let's write our API functions. Tool 1: Finding Rising Articles Here is our function to fetch rising articles. Pay close attention to the docstring ( """Fetches the top...""" ). We aren't writing this for other developers; the ADK actually

Supercharging Adobe Commerce development: introducing the adobe-commerce-docs-mcp server
If you write code for Adobe Commerce or Magento 2, you spend a lot of time waiting. Build times are slow, static content deployment takes forever, but the real time sink is documentation. The EAV architecture, nested XML layouts, and ever-changing GraphQL mutations mean you are constantly Alt-Tabbing to a browser to double check a syntax pattern. Every time you leave your IDE to search the Experience League portal, you lose your train of thought. You copy error codes, dig through unrelated search results, and try to find a working code snippet. It is exhausting. I wanted my coding assistant to just know this stuff without making me look it up. That is why I configured this MCP server. The adobe-commerce-docs-mcp package connects your IDE directly to the official Adobe documentation. It works with Cursor, Claude Desktop, VS Code, and Windsurf, pulling raw markdown docs right into your chat context. The architecture: bridging AI and docs Instead of relying on web search or stale training data, the server queries the live Adobe Experience League site. It indexes the content locally, caches pages, and handles queries via the MCP protocol. 1. BM25 search ranking The server parses the official Adobe sitemap and ranks pages using BM25 relevance scoring. This is the same search algorithm databases use to weigh search term frequency against document length. It means your assistant gets the most relevant setup guide first, not just the page that mentions a keyword the most. 2. Synonyms and fuzzy matching You do not have to query exact terminology. The search engine maps Magento specific synonyms: graphql searches also find pages with gql module searches also match extension cloud searches match ece It also corrects simple typos like chekout or catlog to checkout and catalog. 3. Local caching Network requests are slow, so the server uses two layers of caching: An in-memory cache for recent queries. A persistent file cache on your disk. Sitemap data lasts 24 hours, while downlo

Transitioning to Data Engineering: My Top 4 Essential Tools So Far
Switching focus from Frontend development to Data Engineering means shifting from building user interfaces to architecting robust data pipelines. It’s a completely different mindset, and the learning curve is exciting! As I dive deeper into the world of Data, these are the 4 essential tools and concepts that have become the absolute backbone of my daily learning roadmap: 1️⃣ Python (The Swiss Army Knife): Coming from JavaScript/TypeScript, picking up Python has been a breath of fresh air. From writing custom ETL scripts to data manipulation with Pandas, it's the ultimate language for data manipulation. 2️⃣ Advanced SQL (The Core): It's not just about simple SELECT statements anymore. Mastering Window Functions, CTEs (Common Table Expressions), and query optimization is where the real magic happens when interacting with Data Warehouses. 3️⃣ ETL/ELT Pipelines: Understanding how to efficiently Extract, Transform, and Load data without breaking downstream analytics. Moving from UI state management to Data state management is a game-changer. 4️⃣ Cloud Ecosystems & Modern Stack: Exploring how data flows through modern cloud environments and learning how big data tools manage scale. The transition requires patience, but applying my previous engineering background to these new tools makes the journey incredibly rewarding. 💡 To the Data Engineers in my network: What is the one tool or concept you believe is a "must-have" for someone transitioning into the field today? Drop your advice below!

Building KindaSeen with FastAPI, Next.js, and PostgreSQL
“Did We Already Watch This?” — Building KindaSeen with FastAPI and Next.js A few months ago, my friends and I kept running into the same question whenever we talked about movies, dramas, anime, or variety shows: “Did we already watch this before?” Sometimes we remembered the title but forgot whether we had finished it. Other times, we completely forgot we had already seen it at all. That simple problem inspired me to build KindaSeen, a full-stack personal media repository designed to help users track and organize the media they’ve consumed in one centralized platform. The goal of the project was not only to create a useful application, but also to gain hands-on experience building a real-world full-stack system with modern web technologies.

Running Claude in CI: A GitHub Actions + Claude Code SDK Auto-PR-Reviewer That Costs $0.03 per Review
⚠️ この記事はアフィリエイト広告(プロモーション)を含みます。リンク先で発生した収益の一部が運営者に支払われますが、読者の購入価格には一切影響ありません。 By the end of this article you will have a GitHub Actions workflow that, on every pull_request , runs the Claude Code SDK headlessly, reads only the diff, and posts inline review comments via the GitHub API. I'll show the exact YAML and Python that run in my own repos, the token math that keeps each review at roughly $0.03, and the three failures that cost me a weekend before it worked. Why I stopped piping the full repo into Claude on GitHub Actions My first version did the obvious thing: clone the repo, concatenate every changed file in full, and ask Claude to "review this PR." It worked on toy PRs and exploded on real ones. A 9-file refactor sent ~48,000 input tokens and the review drifted into commentary about code the PR didn't touch. The fix that changed the economics: feed Claude the unified diff with 3 lines of context , not the files. A git diff against the merge base is typically 5–15x smaller than the files it touches. On claude-haiku-4-5 , a median PR in my projects now costs about $0.028 per review (measured across 60 PRs: 4,100 input tokens + 900 output tokens average). The expensive version was hitting $0.40+ on Sonnet because file context dominated. The other lesson: the diff alone is not enough context to judge correctness, but it is enough to catch the 80% of review nits that humans waste time on — unhandled errors, missing null checks, off-by-one, leftover debug prints, secrets in code. So I scoped the prompt to exactly that, and told it to stay silent when unsure. Silence is a feature; a reviewer that comments on everything gets muted by the team within a week. The GitHub Actions workflow YAML that triggers Claude on pull_request This is the full .github/workflows/claude-review.yml . It runs on every PR, restores a uv-cached venv, and calls a Python entrypoint. Note the permissions block — without pull-requests: write the comment-posting step fails with a 403 that GitH

Memory Types Deep Dive Memory Architecture: How It Really Works Access Patterns: Tool vs. Low-Level API Understanding Scope Hands-On: Provisioning a Memory Store Hands-On: Building the Foundry Hosted Memory Agent Running & Deploying the Agent Security Best Practices Quotas, Limits & Regional Availability Conclusion + Next Steps Introduction Imagine you've just shipped a polished AI assistant for your SaaS product. Users log in, ask questions, and get sharp, helpful responses. The launch goes well. Then the complaints start rolling in. "Why does it keep asking me for my name every single session?" "I told it last week that I'm vegetarian — why is it recommending steak again?" "It feels like talking to someone with amnesia." This is the stateless agent problem — one of the most frustrating gaps between the promise of conversational AI and the lived reality of production deployments. Every conversation starts from a blank slate. The agent has no idea who it is talking to, what that person prefers, or what was discussed yesterday, last week, or a month ago. The result is a user experience that feels hollow and repetitive — the opposite of the intelligent, personalized assistant your users were promised. The solution is persistent memory, and Azure AI Foundry Memory is Microsoft's production-grade answer to exactly this problem. Introduced as part of the Azure AI Foundry platform, the Memory Service gives agents the ability to remember facts across sessions, distill long conversation histories into concise summaries, and retrieve the right context at the right moment — all wit
