2+ min ago (576+ words) Real-time codebase indexing with CocoIndex lets you turn a messy, evolving repo into a live semantic API that your AI tools, editors, and SRE workflows can query in milliseconds. Once your repo is indexed, you get a universal "code context service" that many tools can plug into. Some examples: CocoIndex is not "yet another Python script around an embedding model." It gives you a flow definition that describes how data moves from raw files to vector storage, and it tracks enough metadata to support incremental recomputation. For a codebase index, the high-level flow looks like this: This flow is declared once in Python with @cocoindex.flow_def, and CocoIndex turns it into a reproducible pipeline that can be updated with cocoindex update main whenever your repo changes. The first step is teaching the flow where your code lives and which files to…...

4+ min ago (143+ words) Processes (or threads) request resources (mutexes, files, devices, memory pages). A deadlock occurs when processes each hold some resources and wait forever for resources others hold. Simple OS example (classic) Prevention & Avoidance (OS) Prevention: disallow one Coffman condition (e.g., enforce ordering of resource acquisition, or disallow hold-and-wait by forcing processes to request all resources at once). Avoidance: Banker's algorithm (process claims max resources; OS grants only if system stays in a safe state). Works well only with fixed, known maximums. What it means in DBMS Transactions acquire locks (row/page/table locks) to ensure isolation. Two (or more) transactions can form a cycle waiting for locks the others hold. DBMSs commonly use lock managers and wait-for graphs to detect deadlocks and resolve them automatically. DB-specific concepts Lock modes: Shared (S) vs Exclusive (X). Prevention & Avoidance (DBMS)...

4+ min ago (309+ words) I wanted to make a working proof of concept that you can login with an oAuth provider directly in the database. Surreal Database should have this built in, and I am hoping they will in the future just like Gel, Firebase and Supabase! Thanks to Zorimyll for pseudocode in Discord. I make a fully working SurrealDB SvelteKit login with GitHub button that automatically merges with existing users and their email! See Repo. We have three main tables: users, auth_accounts, and auth_providers. We must first create a GitHub oAuth App under GitHub Developer Settings. Save the client_secret and client_id. You can't get the secret later. You will also need two different apps for production and development. There are no environment variables in Surreal, but we can save our data in a safe table we just created. This allows it to be available safely to any…...

7+ min ago (1040+ words) When working in an organization, whether it's a startup, multinational corporation (MNC), or unicorn, there are specific standards and processes that are universally followed. These standards are crucial for ensuring the smooth functioning of the organization, especially in the software or IT industry. One of the most important of these standards is the Software Development Life Cycle (SDLC). The Software Development Life Cycle is a structured process used by the software industry to design, develop, and test software. It provides a systematic approach to ensure that high-quality software products are delivered to end users. Whether you're working at companies like Amazon, Flipkart, or Tesla, all organizations follow these core steps'design, develop, and test'as part of their SDLC. While the SDLC might also involve additional phases, these three are at the heart of the process, ensuring that the final product meets…...

7+ min ago (887+ words) There are countless definitions for DevOps depending on where you look. For instance, if you check Amazon or Red Hat, they each have their unique take on it. However, in simple terms, DevOps is a culture that enhances an organization's ability to deliver applications efficiently. The key focus here is on delivery'how quickly and reliably new features, fixes, or updates reach the end-users. To illustrate the importance of quick delivery, let's consider a popular game like PUBG. Imagine there's an issue with the game, or the developers want to introduce a new feature. If the development work is completed but it takes 10 days to deliver the new version due to multiple stages like unit testing, staging, and final production, that's not ideal. In today's world, where time is critical, such a delay is unacceptable. For instance, if your Android device…...

13+ min ago (721+ words) Infrastructure as Code (IaC) has revolutionized how we manage cloud resources, and AWS Cloud Development Kit (CDK) takes it to the next level by letting you define infrastructure using familiar programming languages. In this guide, I'll walk you through setting up AWS CDK on Windows, from installation to deploying your first stack. AWS CDK is an open-source software development framework that allows you to define cloud infrastructure using programming languages like TypeScript, Python, Java, and C#. Unlike traditional CloudFormation templates written in JSON or YAML, CDK lets you leverage the full power of programming languages'including loops, conditionals, and object-oriented design patterns. Before we dive in, make sure you have: AWS CDK requires Node.js version 14.15.0 or higher. Verify the installation (open PowerShell or Command Prompt): Pro Tip: If you need to manage multiple Node.js versions, consider using nvm-windows. The…...

19+ min ago (349+ words) I'm Casper " product & engineering from Denmark ", and for the last months I've been building a super small tool to solve a problem that kept coming up in my own projects. Some of my side projects needed basic uptime checks, but everything I tried felt heavier than the problem required: " too many features " dashboards packed with stuff I didn't need " enterprise-style UX " complicated onboarding " pricing that felt out of place for a simple monitor I just wanted something that answered one question: "Is my site or API up right now?" So I built the tool I wish existed: Web-Alert.io " a clean, minimal uptime & API monitoring service designed for indie hackers, small projects, and anyone who wants fast, simple checks. " What Web-alert.io Does " Monitor websites + API endpoints " Send email alerts the moment something breaks " Track response times " Check SSL certificate…...
