When managing database backups, key pain points on entry-level servers are memory spikes (Out of Memory crashes) and running out of disk space due to temporary dump files. To validate the efficiency of LunarDump (a zero-disk streaming backup solution), I conducted a benchmark & memory profiling using Memray across a multi-cloud setup based in Jakarta. 🖥️ Test Environment Setup: Server A (Database): Tencent Cloud (Jakarta) — Ubuntu 24.04, 2 vCPU, 2 GB RAM, 40 GB SSD Server B (Lun...

I left programming in PHP when isset() was a lifestyle, array() had just become [] , and types lived in docblocks where the runtime couldn't see them. The language you're returning to grew toward the exact things that pulled me to Ruby and Go: real signatures, immutability you can enforce, pattern matching, values that can't lie about what they are. Almost everything below follows one theme — declare your intent in the code, and let the engine enforce it — which means a huge amount of the...

A LINE MINI App does not automatically need verification before it can be published. The first question is whether your product actually depends on a verified-only capability. If it does, the review is more than a technical launch check: LINE evaluates identity consistency, policy compliance, channel configuration, and whether a reviewer can complete the service's real user flows. A preventable documentation mismatch can add another review cycle, so the best time to audit the submission is...

Abstract Gemini Spark, Google's 24/7 autonomous AI agent, seamlessly connects with Google Workspace. However, connecting to arbitrary external APIs requires extended integration. This article demonstrates how integrating Google Apps Script (GAS) as a Model Context Protocol (MCP) server or Webhook endpoint expands Gemini Spark's capabilities, enabling enterprise-grade workflow automation. Introduction Gemini Spark was officially announced at Google I/O 2026 on May 19, 2026, an...

Week 2. "Why does my pipeline take eleven minutes to install packages I installed yesterday?" Junior Engineer: Last time you left me on a cliffhanger — npm ci is about to run. Where do the dependencies actually come from? Does the runner already have them? Senior Engineer: Think back to Episode 2. What did we say about hosted runners? Junior Engineer: Fresh VM every time. Nothing left over from the last job. Senior Engineer: So answer your own question. Junior Engin...

If your React Native app only speaks English, you're leaving ~75% of smartphone users on the table. Here's the modern stack for shipping a multilingual Expo app without three days of glue code. The Stack react-i18next : translation management (6M+ weekly downloads, TS-first) expo-localization : device locale detection (or react-native-localize for bare RN) Intl : dates, numbers, currencies (built into Hermes) I18nManager : RTL layout flipping Setup...

This is a submission for DEV's Summer Bug Smash: Clear the Lineup powered by Sentry . Project Overview forem is the open source platform behind dev.to itself. I've had it starred and cloned for months and never opened the codebase — it's Rails, and I don't write Ruby. Jess's post was the reason that finally changed. github.com/forem/forem Bug Fix or Performance Improvement #23687 is a one-line report: a user published exactly one post, and the dashboard's...

Running an ERP system for a business in Kenya often comes with significant friction: complex server management, manual KRA eTIMS tax compliance, fragmented M-Pesa payment reconciliations, and identity management headaches. At JengaStack , our mission is to eliminate this complexity. We've built a managed SaaS platform that automates Odoo 19 hosting, localized tax compliance, payment gateways and enterprise security. 🎯 The Problem Kenyan SMEs and growing enterprises face three...

Every SaaS project eventually needs the same thing, a way to charge people. Stripe handles the actual payment processing, but wiring it into Next.js correctly, especially getting webhooks right, is where most of the real work sits. Here is the setup I use for checkout and subscriptions in every SaaS project. 1. The Stripe Client // lib/stripe.ts import Stripe from ' stripe ' ; export const stripe = new Stripe ( process . env . STRIPE_SECR...

An illustrative reporting agent prepares a monthly operating review. It queries finance, CRM, support, and the data warehouse; compares this month with prior periods; investigates material changes; drafts explanations; collects owner comments; and revises the report over several days. By the third revision, its context contains raw query results, discarded hypotheses, repeated instructions, old owner comments, and the current draft. The most important correction—a finance owner rejecting the ...

Shopify Integration for Customer Support: Real-World Patterns That Actually Work Last month, our support team at a mid-sized DTC brand cut ticket resolution time by 40% after integrating Shopify data directly into our helpdesk. Here's what actually moved the needle. The Problem: Context Switching Kills Velocity Agents were jumping between Shopify Admin, Gorgias, and Slack to answer basic questions: "Where's my order?" "Can I modify my subscription?" "Why was I charged twice?"...

I love reading technology history because it explains two powerful things: why a tool was born , and why people eventually moved on . Data formats tell this story perfectly. None of them were random. Each one answered a real pain of its era then later met new pressures: bigger scale, faster systems, better developer experience, lower cost. So instead of treating XML, JSON, and others like a feature checklist, let’s read them like chapters in a long engineering story. 1960s...

I make content about AI products and industry trends, and honestly, a big chunk of the job is repetitive. I collect recent info, look for an angle, draft a script, dump everything into a spreadsheet, and then turn whatever survives into a video. Doing that by hand every day got old fast, because half my time went into moving the same information between tools before I could even start the actual creative part. Most of those steps felt predictable, so at some point I figured I might as well co...

CORS Errors Explained: Every Fix, Every Framework (2026 Guide) TL;DR — A CORS error means the browser blocked a cross-origin request because the server did not explicitly allow it. The fix is always server-side : return the correct Access-Control-Allow-Origin header from your backend. This guide covers every CORS error type, a step-by-step diagnosis flow, and copy-paste fixes for Express, FastAPI, Next.js, nginx, Cloudflare Workers, and Vercel. You can inspect and validate your CORS hea...

What is MCP (Model Context Protocol)? Complete 2026 Guide TL;DR — Model Context Protocol (MCP) is an open JSON-RPC 2.0 specification, introduced by Anthropic in late 2024, that lets AI agents talk to external systems — file systems, databases, APIs, custom services — through a single standardized interface. An MCP server exposes capabilities (tools, resources, and prompts); an MCP client (Claude Desktop, Cursor, Zed, Sourcegraph Cody, your own agent) consumes them. Write the server onc...

That's a rebuild I shipped. The system: a RAG assistant for fraud analysts — ask it "how do we handle card testing followed by a successful auth?" and it should answer from the team's own SOPs and case history. The complaint: the answers were wrong, therefore the model must be dumb, therefore procurement should buy a bigger model. The model was fine. It was answering perfectly — from garbage context. Walk the forensic trail with me, because every step is checkable on your own system this week...

First hour with Claude's browser extension: I pointed it at our LLC registration and watched it work through the forms, finding the right pages, filling the fields, moving on. I sat there holding a coffee, contributing nothing. I thought: I'm going to ship so many products. I shipped one. Here's what happened in between. Everything below was caught before launch. None of it was caught by being clever. It was caught by a process that got built slowly, mostly after being burned. ...

How one frustrated shopper turned a spreadsheet nightmare into a community-powered resource that's saving buyers hours of research. If you've ever shopped for a mini PC, you know the drill. Open a dozen retailer tabs. Copy specs into a spreadsheet. Squint at product titles that hide critical details. Try to figure out whether that $299 model has soldered RAM or upgradeable slots. Give up and buy something you're not quite sure about. This is exactly the frustration that led a developer...

30 Technical Interview Questions You Should Be Able to Explain Out Loud (JS / React / Node) Most interview prep content gives you a definition. Real interviews test something different: can you explain your reasoning clearly, out loud, under a little pressure — not just recite the right words. I put together 30 questions across JavaScript, React, and Node.js. Every answer here is written the way you'd actually say it in an interview, not the way a textbook would write it. How to a...
