Why your scraper plateaus at 5-6 concurrent Chrome instances (and the shared-cookie trap nobody names)

Someone on r/webscraping this week hit the wall I've seen a dozen projects hit: "When I try to use multiple pages (tabs) within a single browser instance, Turnstile doesn't load properly on background or non-focused pages. Because of that, I'm forced to run one browser instance per page... I can do like 5 or 6 browsers simultaneously before throttling my CPU, avg about 30+ solves a minute." 5-...

NeoCognition Just Raised $40M to Fix the One Thing Every AI Agent Gets Wrong

Every AI agent demo looks impressive until you actually depend on one. That 50% task completion rate you've quietly accepted as "normal"? NeoCognition just called it out directly, and raised $40 million to do something about it. The Problem It's Solving The foundational critique that NeoCognition is building on is blunt: current agents — whether from Claude Code, OpenClaw, or Perplexit...

Selenium keeps getting blocked by Cloudflare? Here's what the fingerprint actually catches (and how to stop triggering it)

A post on r/webscraping this week asked a question that keeps coming up: "I'm using Selenium through Chrome, need to scrape ~1M pages at ~1s/page, but every request hangs 7-8s on a Cloudflare challenge." At 7 seconds per page, 1M pages takes 81 days. That's not a rate limit problem. That's a detection problem — and you can't fix it with more threads. The replies to that post are a goldmine of ad...

DPDPA compliance is a cloud config problem

DPDPA compliance is a cloud config problem

A compliance lead told me last week: "We're buying a ₹40L DPDPA compliance tool. We'll be ready by deadline." I asked: "Do you know which S3 buckets contain user PII?" She didn't. Neither did the CTO. Here's the reality: DPDPA isn't a compliance-tool problem. It's a cloud-config problem wearing a legal costume. The 7 misconfigurations that cause DPDPA violations (and cost ₹2-10L to fix post...

The Definitive Guide to Lightweight Kubernetes: KIND, Minikube, MicroK8s, K3s, Vcluster, k0s, and RKE2 Compared

TL;DR — There is no single "best" lightweight Kubernetes. KIND wins CI/CD, Minikube wins local dev UX, MicroK8s wins on Ubuntu, K3s wins edge and production, Vcluster wins multi-tenancy, k0s wins zero-dependency ops, and RKE2 wins enterprise compliance. This post explains why — with architecture diagrams, feature tables, and real-world guidance. Table of Contents Why Lightweigh...

Practical Guide: Building an Active-Active Multicloud Cell-Based Architecture

1. Introduction A multicloud cell-based architecture represents the pinnacle of fault isolation and vendor neutrality. By distributing autonomous "cells" across different cloud provider, such as placing Cell Alpha in AWS and Cell Beta in Azure, you eliminate the risk of a single cloud provider's regional or global outage taking down your entire application. At the end of this tutorial, ...

Add cryptographic authorization to AI agents in 5 minutes

You have AI agents calling each other. You're using API keys or mTLS. You're worried it's not enough. API keys authenticate. They don't authorize. They don't scope. They don't audit delegation chains. Here's how to add all four in under 5 minutes using Codios — an A2A security layer built on signed capability contracts. What you'll build Two agents with cryptographic identit...

Building a website with Replit and Vercel

I recently built a personal website (absterellio.com) to aggregate the various projects I've worked on as well as to compile my information in one location. (Also, for fun) :). With AI tools and simple hosting platforms it's pretty frictionless to spin up a website. In particular, with agentic AI tools such as Replit, building a website is as simple as it's ever been. I wanted to write a quick gu...

Claude and I aren't vibing at all

I really enjoyed working with Opus 4.6 in Copilot, especially for tasks that required a bit of creativity (e.g. it was much better at building a landing page compared to GPT-5.3-Codex), but I never got a Claude subscription. I finally did, at last. After spending 24 hours with Claude Code in VS Code, I've come to the conclusion that it is focused entirely on "vibe coding". It will absolutely do a...

Kiwi-chan Devlog #007: The Audit Never Sleeps (and Neither Does My GPU)

Okay, folks, buckle up. It's been a busy four hours with Kiwi-chan. We're still battling the core survival loop – get wood, build a base. Sounds simple, right? Wrong. So, so wrong. The biggest issue continues to be the relentless auditing. I've cranked up the rules around item collection again. Apparently, Kiwi-chan was getting a little too lax about actually picking up the logs after chopping th...
