Every World Cup there's a moment. Some player nobody outside their domestic league had heard of scores an absolute screamer in a knockout match, and by the time they've finished celebrating, their follower count is climbing like a rocket. I always found that fascinating, but I could never see it happening. By the time the "X gained 3M followers!" tweets show up, the surge is already over. So this tournament I built a little tracker that snapshots player follower counts on a schedule and shows me the growth curve in near real-time. Here's how it works. The problem with doing this "properly" My first instinct was the official APIs. That died fast. Instagram's Graph API won't give you follower counts for accounts you don't own. TikTok's Research API is academics-only and takes weeks of applications. X's API now starts at $100/month and climbs steeply from there. I just wanted public follower counts — numbers anyone can see by opening the app. I didn't want a data partnership and a legal review. I ended up using the SociaVault API , which wraps public profile data from each platform behind one key. One request, one credit, JSON back. The shared client Everything runs through one tiny helper: // Node 18+ has fetch built in const API_KEY = process . env . SOCIAVAULT_API_KEY ; const BASE = " https://api.sociavault.com " ; async function sv ( path , params ) { const url = new URL ( BASE + path ); Object . entries ( params ). forEach (([ k , v ]) => url . searchParams . set ( k , v )); const res = await fetch ( url , { headers : { " X-API-Key " : API_KEY } }); if ( ! res . ok ) throw new Error ( ` ${ res . status } ${ await res . text ()} ` ); return res . json (); } Grabbing follower counts across platforms Each platform nests the count slightly differently, so I use fallback chains to stay defensive: async function instagramFollowers ( username ) { const data = await sv ( " /v1/scrape/instagram/profile " , { username }); const p = data . data ?. user ?? data . data ?? data

GraphQL: A Complete Guide for Developers in 2026 NEWS: MY GAME JUST LAUNCHED Flip Duel Card Battle - Apps on Google Play Outsmart rivals in 1v1 card duels. Joker, bluff, ranked PvP. 5 rounds. play.google.com If you have built more than a couple of APIs, you have probably felt the friction of REST at scale. You ship an endpoint, the frontend team asks for one more field, you version the route, the mobile team needs a different shape of the same data, and six months later you are maintaining /v3/users/:id/full next to /v2/users/:id/summary and nobody remembers which one the Android app actually calls. GraphQL was built to kill that exact pain. It is a query language and runtime that lets clients ask for precisely the data they need — no more, no less — from a single endpoint, against a strongly typed schema that doubles as living documentation. This guide walks through GraphQL from first principles to production concerns. It is aimed at working developers, so expect schema definitions, resolvers, real queries, the N+1 problem, federation, security, and the parts of the ecosystem that actually matter in 2026. By the end you should be able to decide whether GraphQL belongs in your stack and how to build it without shooting yourself in the foot. What GraphQL Actually Is GraphQL is a specification, not a library or a framework. It was created at Facebook in 2012 to power their mobile apps, open-sourced in 2015, and is now governed by the GraphQL Foundation under the Linux Foundation. The spec defines a query language, a type system, and an execution model — but it deliberately says nothing about which database you use, which programming language you implement it in, or how you transport requests over the wire. That last point trips people up, so let it sink in: GraphQL is transport-agnostic and storage-agnostic. Most implementations run over HTTP with JSON, but that is a convention, not a requirement. Your resolvers can pull data from PostgreSQL, a REST microservice, a gR

Introduction Extracting data from older websites is a technical challenge that goes beyond simple copy-pasting. The example website provided illustrates this perfectly: its outdated design, reliance on mouse-over interactions, and lack of structured export options create a perfect storm of extraction difficulties. This article dissects these challenges and provides a roadmap for extracting both visible content and mouse-over images while preserving data integrity. The Core Problem: Legacy Technology Meets Modern Needs The website's URL parameters ( screen_width=0&screen_height=0 ) immediately signal a legacy system likely built for a bygone era of fixed-width displays. This design choice breaks modern scraping tools that expect responsive layouts. The mouse-over images, critical to the site's content, are dynamically loaded via JavaScript , meaning they don't exist in the initial page source. This requires simulating user interactions to trigger their appearance, a task beyond basic HTML parsing. Why Manual Extraction Fails Attempting to manually save images or copy text from this site is a losing battle. The mouse-over images, for instance, are not directly downloadable – they're embedded in JavaScript events. Even if you could save them individually, maintaining their association with the corresponding visible content would be error-prone and time-consuming. This method also fails to scale for larger websites with hundreds of such elements. The Technical Solution: A Multi-Pronged Approach Effective extraction requires a combination of techniques: Browser Automation: Tools like Selenium or Puppeteer can simulate mouse movements to trigger hover events, capturing both visible and hidden content. This method mirrors human interaction , ensuring all dynamic elements are revealed. Network Request Inspection: Analyzing the website's backend requests using browser developer tools can reveal direct URLs for mouse-over images , bypassing the need for hover simulation. This

When I started building , I needed reliable access to Instagram data. Like many developers, my first instinct was to use a self-hosted solution such as instagrapi. It worked for experimenting, but once I started depending on it for production workflows, I spent more time maintaining the scraper than building features. Eventually I switched to HikerAPI, a hosted REST API for Instagram. This post isn't about saying one approach is universally better—it's about why it ended up being the better fit for my project. My use case I needed to fetch Instagram profile data for . The requirements were fairly simple: Look up public profiles Process structured JSON Integrate the results into my backend Avoid spending time maintaining login sessions I wasn't interested in reverse engineering Instagram every time something changed. Getting started One thing I liked was that it behaves like a normal REST API. Authentication is done through an x-access-key header, so integrating it into an existing Python backend took only a few minutes. import requests headers = {"x-access-key": "YOUR_KEY"} r = requests.get( " https://api.hikerapi.com/v2/user/by/username?username=instagram ", headers=headers, ) print(r.json()) That's enough to start requesting data and integrating it into your own application. If you want to explore the API, you can find it at HikerAPI. Why I moved away from self-hosted scraping I originally tried , including instagrapi. There wasn't a single issue that made me switch—it was the accumulation of small operational problems: Login sessions expiring Accounts getting challenged Temporary bans Instagram changing internal behavior Regular maintenance after updates None of those problems are impossible to solve. The question became whether solving them was the best use of my time. For my project, the answer was no. I'd rather focus on shipping features than maintaining scraping infrastructure. Tradeoffs Using a hosted API isn't free. Pricing starts at $0.001 per request, wi

If you've ever needed a list of local businesses - every dentist in Manchester, every plumber in Leeds - with their contact details , you've probably hit the same wall I did: Google's Places API is rate-limited, costs money once you scale, and annoyingly doesn't return email addresses at all. Copy-pasting from Maps by hand is soul-destroying past the first ten rows. Most "scrapers" give you the name and a phone number, then stop right where the value starts: the email . This guide shows a practical way to pull structured business data straight from Google Maps and auto-enrich each result with emails, extra phones, and social links - no Google API key, exportable to JSON/CSV/Excel, and callable from code. What you actually get per business { "name" : "Ringway Dental - Cheadle" , "address" : "187 Finney Ln, Heald Green, Cheadle SK8 3PX" , "phone" : "0161 437 2029" , "website" : "https://www.ringwaydental.com/" , "rating" : 5 , "reviewsCount" : 598 , "category" : "Dental clinic" , "lat" : 53.37 , "lng" : -2.22 , "emails" : [ "reception@ringwaydental.com" ], // ← enriched from the website "socialLinks" : { "facebook" : "..." , "instagram" : "..." }, "extraPhones" : [ "..." ] } The first block (name → coordinates) comes from Maps. The emails / socialLinks / extraPhones are the bit that makes a list actually usable for outreach - they're crawled from each business's own website. The fast way: a ready-made Actor Rather than build and babysit the scraping yourself, I packaged this as an Apify Actor: Google Maps Scraper . You give it search terms + locations; it returns enriched rows. Input: { "searchTerms" : [ "dentists" ], "locations" : [ "Manchester, UK" ], "maxPlacesPerSearch" : 50 , "scrapeContacts" : true , "relatedEmailsOnly" : true } That's it. scrapeContacts: true turns on the website crawl for emails/socials; relatedEmailsOnly keeps only emails that belong to the business's own domain (so you don't get random gmail noise). Call it from code (Python) Every Apify Act

In sandbox runtimes, "isolation" is the core requirement. qwrap (based on bwrap user namespace) and Container (podman/docker) are two mainstream backends. They solve the same problem — running code in a restricted environment — but take completely different paths. This article uses extensive analogies to help you understand the similarities and differences. Building Intuition: Two Ways to "Lock the Door" Imagine you need to confine someone you don't fully trust in a room to do work: qwrap approach : In your existing house, you put up a partition to wall off a corner, leaving only a small window to pass materials through. The walls are still the original walls, the floor is still the original floor, but the person can only see what's inside the partition. Container approach : You build a shipping container with its own independent power, water, and ventilation systems. Put the person inside, close the door. They feel like they're in a complete little house, completely unaware of what's outside. This is the most fundamental difference: qwrap is lightweight view isolation, Container is complete environment encapsulation . What is qwrap (bwrap user namespace) qwrap uses bubblewrap (bwrap) under the hood, a sandboxing tool that leverages Linux user namespaces. How it Works Host filesystem ├── /usr/bin/python3 ← Host's Python ├── /home/user/project/ ← User project └── /tmp/secrets/ ← Sensitive files qwrap sandbox view (what the process sees) ├── /usr/bin/python3 ← bind-mounted in, read-only ├── /workspace/ ← Only the project directory is exposed └── (/tmp/secrets/ doesn't exist) ← Completely invisible Key mechanisms: User Namespace : The process thinks it's root, but actually maps to an unprivileged user on the host Mount Namespace : Only bind-mounts necessary directories in, everything else is invisible No images, no layers, no network namespace (unless explicitly configured) Analogy: VPN Split Tunneling qwrap is like split-tunneling rules on your phone — you're not wrap

[Excerpted from THE QUANTUM COLLAPSE CHRONICLES — not science fiction, but a grounded forecast of what may come when quantum computation dismantles the cryptographic foundations of our digital civilization. These articles explore the collapse of computational trust and the brutal reconstruction of the world that follows.] The history of human civilization is often defined by sudden, violent shifts in the nature of power. We speak of the fall of empires, the industrial revolutions, and the splitting of the atom. But in the mid-2030s, the world experienced a collapse that was not made of steel or stone, but of mathematics. It was a quiet, clinical, and utterly devastating unraveling of the digital fabric that held modern society together. To understand The Quantum Collapse , one must look past the headlines of the era and into the humming, sub-Kelvin depths of the dilution refrigerators that changed everything. This is the story of how the transition from probabilistic experimentation to deterministic computation rendered the world's secrets transparent and its economies obsolete. The Death of Noise: The Rise of Dr. Aris Thorne For the first three decades of the 21st century, quantum computing was a game of chance. Scientists operated in the era of Noisy Intermediate-Scale Quantum (NISQ) devices—machines so temperamental and prone to error that every calculation was a desperate struggle against environmental noise. In those days, a single stray photon or a microscopic fluctuation in temperature could collapse a delicate superposition, turning a groundbreaking calculation into useless digital static. The turning point arrived in 2036 at the Institute for Advanced Quantum Engineering (IAQE) in the High Sierras. The air in the facility didn't vibrate with the erratic drone of the late 2020s; instead, it carried a heavy, rhythmic thrum—the sonic signature of the Lattice-Array-9 (LA-9). At the center of this revolution was Dr. Aris Thorne, the lead architect of the LA-9 pr

When you build Shopify apps or integrations, pagination becomes important very quickly. A small test store may have a few products and orders. A real merchant store can have thousands of products, variants, orders, customers, inventory items, metafields, and fulfillment records. You cannot fetch all of that data in one Shopify GraphQL request. You need pagination. More importantly, you need pagination that performs well. Poor Shopify GraphQL pagination can create slow syncs, API throttling, timeout errors, duplicate processing, and incomplete exports. This post explains how Shopify GraphQL pagination works and how to handle large Shopify datasets in a practical way. What Shopify GraphQL Pagination Solves Pagination lets your app retrieve data in smaller chunks. Instead of asking Shopify for 50,000 products at once, your app asks for 100 or 250 products per request. Shopify returns the data and gives your app information about the next page. This protects your app from huge responses and protects Shopify from heavy requests. It also gives your integration more control over retries, progress tracking, and background processing. Shopify Uses Cursor-Based Pagination Shopify GraphQL uses cursor-based pagination. That means you do not request data using page numbers. You request the next page using a cursor from the previous response. A basic product pagination query looks like this: query GetProducts ( $cursor : String ) { products ( first : 100 , after : $cursor ) { nodes { id title handle updatedAt } pageInfo { hasNextPage endCursor } } } The first time you run this query, pass cursor as null. Shopify returns the first 100 products and gives you an endCursor . Use that endCursor as the after value in the next request. Keep doing this until hasNextPage is false. Why Cursors Work Better Than Page Numbers Offset pagination usually works like this: page=1 page=2 page=3 or: offset=5000&limit=100 This approach becomes inefficient when datasets grow. The system may need to sk

If you scrape Weibo's hot-search board you get a snapshot: ~50 trending topics, ranked, right now. That's table stakes — and on its own it's almost useless as a signal. The value isn't what is trending; it's what's moving : which topic just jumped 30 places in 20 minutes, which is decaying, which is brand-new this hour. That's velocity , and velocity is where the signal lives — for brand-crisis teams, consumer-trend desks, and anyone modelling attention in China. The catch: a single scrape can't tell you velocity. You have to diff the board against its own past, reliably, run after run. That's a stateful pipeline, and it has a few non-obvious gotchas. Here's the shape of the problem and how to handle it. Why a snapshot isn't enough Rank-right-now tells you nothing about trajectory. "#7" could be a topic on its way to #1 or one fading out of the top 50 — same row, opposite meaning. To act on a trend you need the derivative : direction, speed, and how long it's been climbing. None of that is in a single pull. The trending-delta problem Three things make "just diff the board" harder than it looks: Key by identity, not position. You can't track a topic by its rank — rank is the thing that changes. Key by the topic itself (its text/keyword) or your deltas are nonsense. State has to survive between runs. A scheduled scrape is stateless by default — each run starts cold. To compute "this rose 12 places since 30 minutes ago," you must persist the previous board and reload it next run, keyed so independent schedules don't overwrite each other. The board churns. Topics appear, peak, and fall off. You want each tagged new / rising / falling / steady / dropped , plus how long it's been on the board and its running peak — none of which exist in the raw snapshot. How to handle it (the pattern) current = pull_board () # [{topic, rank, heat}, ...] previous = load_state ( key ) # durable store that persists across runs for t in current : prev = previous . get ( t . topic ) # match o

The Anti-Bot Detection Checklist I Use Before Every Scraping Project Every scraping project I take on starts with this checklist. Not because I'm paranoid — but because I've learned the hard way that production scrapers fail silently. They return 200 OK with garbage data, or they get rate-limited so gradually you don't notice for days. This is the systematic approach I've refined over 50+ scraping projects. Pre-Scraping: Know Your Target 1. Identify the CDN and Protection Stack Before writing a single line of code, check what you're up against: # Check CDN and headers curl -I https://target-site.com # Look for these common protection headers: # X-Engine: akamai-html-protection # X-Served-By: DataDome # cf-ray: Cloudflare # X-Bot-Status: blocked Common protection platforms: Cloudflare → Look for cf-ray and __cfduid cookies DataDome → Look for datadome in headers or scripts PerimeterX → Look for _pxff cookies Akamai → Look for akamai-html-protection headers 2. Check Robots.txt Respectfully curl https://target-site.com/robots.txt | grep -v "^#" Don't take this as gospel — but it's a good signal. If they explicitly disallow your use case, that's a flag. 3. Map the Site's JavaScript Rendering Some sites are fully static (fast, easy). Others render everything with JavaScript (need Playwright/Puppeteer). Check: // Quick check - fetch raw HTML vs rendered content // If they differ significantly, you need JS rendering const https = require ( ' https ' ); const html = await fetch ( ' https://target.com ' ). then ( r => r . text ()); const hasAngularVueReact = /ng-app|vue|react|__NEXT_DATA__/i . test ( html ); console . log ( ' Needs JS rendering: ' , hasAngularVueReact ); Code-Time: Defensive Patterns 4. Rotate User Agents const USER_AGENTS = [ ' Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36 Chrome/120 Safari ' , ' Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 Chrome/120 Edge/120 ' , ' Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 Chro

This is the story of how a mundane complaint — "the VPN is slow" — turned into a US patent application. Not a granted patent. An application . I want to be precise about that from the start, because the distance between the two is the whole point of this post. It started with a slow VPN The company I work for had an internal VPN that everyone routed through. It lived in the Tokyo office, it was old, and it was not something I built. Then the complaints started arriving — from a lot of people, all saying the same thing: it's slow. I work from Thailand most of the time. That detail matters. If that aging box in Tokyo had fallen over, I would have been the person furthest from the power button, in the worst position to fix it. A slow VPN is annoying. An unreachable VPN, when you're a few thousand kilometers away, is a real problem. So I started moving it to the cloud. I stood up a WireGuard VPN — modern, fast, and something I could actually reason about and operate remotely instead of inheriting a black box. Down the WireGuard rabbit hole Around that time I was deep into building my own iPhone apps. So the cloud migration turned into a personal project on the side: I built my own server and wired WireGuard into an iPhone app of my own. And to do that properly, I started studying how WireGuard actually works under the hood — the Noise protocol, the handshake, the key exchange. That study is where everything else came from. I wasn't trying to invent anything. I was just trying to understand the thing I was now responsible for. The SYN flood that primed my brain Not long before, the same company had been hit with a SYN flood attack. If you've dealt with one, you know it lodges the mechanics of connection handshakes firmly in your head — the back-and-forth, the round trips, the cost of every "hello" before any real data moves. So I had handshakes on the brain. And then, reading through how WireGuard establishes a session, a thought stopped me: Wait — does it really handsha
