1. Introduction For more than a decade the WordPress SEO landscape has been dominated by a small group of plugins. Yoast SEO, Rank Math, and All in One SEO have collectively powered millions of sites and shaped how authors think about optimisation. These plugins are very good at what they were designed to do. They analyse content, highlight issues, and … Continue reading “Next Generation AI SEO for WordPress Just Launched And its Totally Free!!!”

Search engines no longer operate alone. Your content is now consumed byGoogle, Bing, Perplexity, ChatGPT, Claude, Gemini, and dozens of otherAI driven systems that crawl the web and extract answers. Classic SEO focuses on ranking. Modern discovery also requires AEO (Answer Engine Optimization) which focuses on being understood and extracted by AI systems. A marketing page must therefore satisfy four … Continue reading “A Simple Script to Check if Your Page is SEO and AEO Friendly”

By Andrew Baker, Chief Information Officer, Capitec Bank The Engineering Behind Capitec Pulse 1. Introduction I have had lots of questions about how we are “reading our clients minds”. This is a great question, but the answer is quite complex – so I decided to blog it. The article below really focuses on the heavy lifting required to make agentic … Continue reading “Why Capitec Pulse Is a World First and Why You Cannot Just Copy It”

When you share a link on WhatsApp, LinkedIn, X, or Instagram and nothing appears except a bare URL, it feels broken in a way that is surprisingly hard to diagnose. The page loads fine in a browser, the image exists, the og:image tag is there, yet the preview is blank. This post gives you a single unified diagnostic script that … Continue reading “The Hitchhikers Guide to Fixing Why a Thumbnail Image Does Not Show for Your Article on WhatsApp, LinkedIn, Twitter or Instagram”

Andrew Baker | March 2026 Companion article to: https://andrewbaker.ninja/2026/03/01/the-silent-killer-in-your-aws-architecture-iops-mismatches/ Last week I published a script that scans your AWS estate and finds every EBS volume and RDS instance where your provisioned storage IOPS exceed what the compute instance can actually consume. That problem, the structural mismatch between storage ceiling and instance ceiling, is important and expensive and almost completely invisible … Continue reading “Knowing Your IOPS Are Broken Is Not As Valuable As Knowing They Are About To Break”

If you have ever sat there manually clicking through a UI, copying error messages, and pasting them into Claude just to get help debugging something, I have good news. There is a better way. Chrome MCP gives Claude Desktop direct access to your Chrome browser, allowing it to read the page, inspect the DOM, execute JavaScript, monitor network requests, and … Continue reading “Install Chrome MCP for Claude Desktop in a single script”

If you run multiple Chrome profiles or keep several windows open per app, switching between them on macOS becomes irritating fast. Clicking the Dock icon only brings the app forward. Clicking it again does nothing useful. So you right click, scan the window list, and manually choose the one you want. It breaks flow and adds cognitive drag to something … Continue reading “Shift + Click Your Dock Icon to Cycle App Windows on macOS”

You updated a plugin five minutes ago. Maybe it was a security patch. Maybe you were trying a new caching layer. You clicked “Update Now,” saw the progress bar fill, got the green tick, and moved on with your day. Now the site is down. Not partially down. Not slow. Gone. A blank white page. No error message, no admin … Continue reading “You just Uploaded a new Plugin and your WordPress Site Just Crashed. Now What?”

If you publish online, you should periodically search for yourself, not out of ego but out of discipline. The internet is an echo system, and if you do not measure where your ideas travel, you are operating blind.

If you are doing 20 builds before finding the real issue, the problem isnot intelligence. It is workflow design. Claude defaults to probabilistic reasoning. It produces the most likelyexplanation. That is useful for writing. It is disastrous for debugging. You must force it into instrumentation mode. This article shows exactly what to configure, where to put it, and howto enforce … Continue reading “Stop Claude Guessing. Force It to Debug Like an Engineer.”

Andrew Baker | 01 Mar 2026 | andrewbaker.ninja You want one script that does everything. No digging around in settings. No manually editing JSON. No clicking Developer, Edit Config.

Why You Would Want This Out of the box, … Continue reading “Enable Claude Desktop To Run Bash MCP : Fully Scripted Installation”

If you use Claude Desktop to edit code, write patches, or build plugin files, you have probably hit the same wall I did: Claude runs in a sandboxed Linux container. It cannot read or write files on your Mac. Every session resets. There is no shared folder. You end up copy pasting sed commands or trying to download patch files … Continue reading “How to Share Files Between Claude Desktop and Your Local Mac Filesystem Using MCP”

GitHub is not just a code hosting platform. It is your public engineering ledger. It shows how you think, how you structure problems, how you document tradeoffs, and how you ship. If you build software and it never lands on GitHub, as far as the wider technical world is concerned, it does not exist. This guide walks you from nothing … Continue reading “Simple Guide to Publishing Your Code on GitHub”

Most WordPress plugin developers eventually hit the same invisible wall: you ship an update, everything looks correct in the zip, the version number changes, the code is cleaner, and yet users report that the old JavaScript is still running. You check the file. It is updated. They clear cache. Still broken. Here is the uncomfortable truth: WordPress plugin uploads do … Continue reading “How to Make WordPress Plugin Upgrades Clean Up Properly”

If you run a WordPress site behind Cloudflare, your page view numbers are lying to you. Jetpack Stats, WP Statistics, Post Views Counter and nearly every other WordPress analytics plugin share the same fatal flaw: they count views on the server. When Cloudflare serves a cached HTML page (which is the entire point of using Cloudflare), WordPress never executes. The … Continue reading “CloudScale PageViews – Free WordPress Analytics that Work Behind Cloudflare”

If you run a technical blog on WordPress, you know the pain. You paste a markdown article with fenced code blocks, Gutenberg creates bland core/code blocks with no syntax highlighting, no copy button, no dark mode. You end up wrestling with third party plugins that haven’t been updated in years or manually formatting every code snippet. I built CloudScale Code … Continue reading “Building a Better Code Block for WordPress: CloudScale Code Block Plugin”

Andrew Baker · February 2026 · andrewbaker.ninja 1 The Problem with TTFB Time to First Byte has been the go to diagnostic for server responsiveness since the early days of web performance engineering.

That measurement … Continue reading “Net Time to First Byte (NTTFB): The Metric TTFB Should Have Been”

On a quiet Friday evening in late March 2024, a Microsoft engineer named Andres Freund was running some routine benchmarks on his Debian development box when he noticed something strange.

Gartner says 40% of agentic AI projects will fail by 2027. I think they’re being optimistic. Walk into almost any large enterprise right now and you’ll find the same scene: a glossy AI pilot, a proud press release, a steering committee meeting monthly to “track progress,” and an absolutely zero percent chance that any of it ever reaches production at … Continue reading “The Pilot Trap: Why Your AI Project Will Never See Production”

If you run a WordPress site for any length of time, the database quietly fills with junk. Post revisions stack up every time you hit Save. Drafts you abandoned years ago sit there. Spam comments accumulate. Transients expire but never get deleted. Orphaned metadata from plugins you uninstalled months ago quietly occupies table rows nobody ever queries. On a busy … Continue reading “WordPress Space Cleanup: A Free WordPress Databas, Media Library Cleanup Plugin and PNG to JPEG convertor”

1. What is Minification Minification is the process of removing everything from source code that a browser does not need to execute it. This includes whitespace, line breaks, comments, and long variable names. The resulting file is functionally identical to the original but significantly smaller.

By Andrew Baker, CIO at Capitec Bank There is a category of enterprise technology vendor whose approach to pricing is so fundamentally at odds with how purchasing decisions actually get made that it borders on self-defeating. Their commercial model is built on access gates, bundled tiers, and a deeply held belief that controlling what a customer can see before they … Continue reading “Stop Selling Hampers: Why Enterprise Software Tiering Is a Self-Defeating Strategy”

I’ve been running this blog on WordPress for years, and the backup situation has always quietly bothered me. The popular backup plugins either charge a monthly fee, cap you on storage, phone home to an external service, or do all three. I wanted something simple: a plugin that makes a zip file of my site, stores it locally, runs on … Continue reading “WordPress Totally Free Backup and Restore: CloudScale Backup Plugin – Does Exactly What It Says”

If you’ve run your site through Google PageSpeed Insights and seen the “Eliminate render-blocking resources” warning, you’ve probably wondered why something that sounds so simple is so hard to actually fix. The answer is that WordPress makes it surprisingly easy to load JavaScript the wrong way — and surprisingly difficult to fix it without either a heavyweight performance plugin or … Continue reading “Eliminating Render-Blocking JavaScript: The Easiest Core Web Vitals Win You’re Not Taking”

Published on andrewbaker.ninja | Enterprise Architecture & Banking Technology There is a quiet revolution happening in physics laboratories around the world, and most of the people who should be worried about it are not paying attention yet.

The COBOL apocalypse conversation this week has been useful, because it has forced the industry to confront something it has been avoiding for decades. But most of the coverage is stopping at the wrong point. Everyone is talking about COBOL. Nobody is talking about the architectural philosophy that COBOL gave birth to, the one that outlived the mainframe, survived the … Continue reading “Core Banking Is a Terrible Idea. It Always Was.”

Written by Andrew Baker | February 2026 I spent years working across major financial institutions watching vendors charge eye-watering licence fees for tools that were, frankly, not that impressive. That instinct never left me. So when I wanted serious SEO for my personal tech blog, I built my own WordPress plugin instead of paying $99/month for the privilege of checkbox … Continue reading “CloudScale SEO AI Optimiser: Enterprise Grade WordPress SEO, Completely Free”

Anthropic published a blog post on Monday. Not a product launch, not a partnership announcement, not a keynote at a major conference.

By Andrew Baker, CIO at Capitec Bank There is a truth that most technology vendors either do not understand or choose to ignore: the best sales pitch you will ever make is letting someone use your product for free. Not a watered-down demo, not a 14-day trial that expires before anyone has figured out the interface, but a genuinely generous … Continue reading “The Quiet Power of Free Tier: Why Cloudflare Gets It Right”

Aurora Serverless v2 promises the dream of a database that automatically scales to meet demand, freeing engineering teams from capacity planning. The reality is considerably more nuanced.

The topics covered here span the entire lifecycle of … Continue reading “Scaling Aurora Serverless v2 PostgreSQL: A Production Deep Dive”

There is a peculiar sport played in large organisations. It looks like leadership and sounds like governance, hiding behind frameworks, maturity models, and operating rhythms. But in reality it is something far less noble. It is corporate heckling. Corporate heckling is what happens when a function narrates from the sidelines with low context and high confidence. It is the art … Continue reading “The Futility of Corporate Heckling”

There is a version of the Apache Kafka story that gets told as a series of press releases. ZooKeeper removed. KRaft promoted. Share groups landed. Iceberg everywhere. Each headline lands cleanly, and then platform teams go back to their actual clusters and wonder what any of it means for them. This post is the other version. It is what happened … Continue reading “The Year Kafka Grew Up: What version 4.x Actually Means for Platform Teams”

Every Java developer has seen it. The stack trace that ends conversations. The production incident that ruins a Friday afternoon. The crash that leads to the post-mortem nobody wants to write.

Tony Hoare, the man who … Continue reading “The Billion Dollar Mistake That Java Still Hasn’t Fixed (But Might Be About To)”

1. The Shoe Planet Problem In The Hitchhiker’s Guide to the Galaxy, there is a planet where the inhabitants become so obsessed with shoes that the shoes eventually take over. The civilisation does not collapse because it lacks intelligence. It collapses because something peripheral accumulates mass until it dominates everything essential. Leadership bloat is the corporate equivalent of that shoe … Continue reading “The Leadership Event Horizon”

This is an assessment. It is not balanced. It is not here to validate your instincts, your planning methodology, or your confidence in the delivery framework you inherited.

1. The Uncomfortable Silence After the Music Stops Every organisation that runs on defensive process has a soundtrack. Standups hum at 9am. Sprint reviews crackle on Fridays. Retros generate their familiar low frequency guilt. Planning ceremonies fill the gaps. Remove all of it and the first thing you hear is silence, and silence in a corporate environment is terrifying because … Continue reading “Naked Teams: What Happens After You Strip Away Every Defensive Process”

1. Ownership Has Been Turned Into a Moral Shortcut Ownership has become one of the most lazily celebrated concepts in modern organisations. Leaders demand it reflexively, teams chase it performatively, and entire operating models are justified by invoking it as if ownership itself produces outcomes. It does not. Ownership is merely a structural choice, and when that structure is poorly … Continue reading “Corporate Culture: Toxic Ownership Optimised for Leaders, Not for Clients”

1. Fear, Motion, and the Illusion of Progress In the last few months I’ve come up with two of the most powerful fraud controls of my career. Not in a workshop.

1. The Physics Makes the Point Brutal Here is the uncomfortable physics problem. If two Death Stars come into existence at the same time, and one fires first, the other never gets to respond.

Leadership failures rarely announce themselves politely. They arrive disguised as “can we just check in?” or “let’s align on a better way of working.” It sounds constructive, even mature. But scratch the surface and the origin story is almost always the same: something went wrong, and the organisation does not know how to deal with it cleanly. What follows is … Continue reading “Leadership, Ownership and Fragility”

1. Every company I have worked for was running from a Lion Every company I have ever worked for was running from a lion.

An ancient taxonomy for very modern dysfunction The original seven deadly sins endure because they describe human failure modes, not theology. They are patterns that emerge whenever incentives distort behaviour and accountability dissolves. That makes them an uncomfortably precise model for corporate culture. Below, each sin is paired with its mirrored virtue. Not as moral advice, but as a design … Continue reading “The 7 Deadly Sins of Corporate Culture”

Or: How Organisations Confuse Accountability with Paperwork 1. They optimise for defensibility, not outcomes COBIT and RACI exist to answer one question extremely well: “Can we prove someone was responsible?” They are almost entirely indifferent to the harder question: “Did anything improve?” Both frameworks reward traceability over truth. If an initiative fails, the organisation can point to a process, a … Continue reading “10 Reasons to Dislike COBIT and RACI”

In One Flew Over the Cuckoo’s Nest, the story is set inside a psychiatric institution run not for healing, but for control. The ward is orderly, predictable, and calm on the surface. Patients follow rigid routines. Group therapy sessions exist, but nothing meaningful ever changes. Any behaviour that challenges the system is treated as dangerous. Non conformity is labelled dysfunction. … Continue reading “One Flew Over the Cuckoo’s Nest: The Escape from Agile”

Or: How We Turned Software Development Into Ticket Farming and Ceremonial Theatre 1. Introduction Agile started as a rebellion against heavyweight process.

1. Estimation Fails Exactly Where It Is Demanded Most Estimation is most aggressively demanded in workstreams with the highest discovery, the highest uncertainty, and the highest intellectual property density. This is not an accident. The more uncomfortable the terrain, the more organisations reach for the false comfort of numbers. In these environments, estimation is not just wrong, it is structurally … Continue reading “The Dishonest Process of Technology Planning”

Email trees are not an accident. They are the predictable outcome of organisations repeatedly using the wrong tool for the wrong job.

The result is wasted time, fragmented thinking, and an extraordinary amount of invisible labour. … Continue reading “Email Trees, One Finger Typists, and the Corporate Refusal to Collaborate Properly”

1. The Dead Giveaway Is the Meeting Itself There is a reliable early warning signal that corporate herding is about to occur: the meeting invite. No meaningful agenda. No pre reading.

For the life of me I can never remember where this sits in the settings, all I know is that it irritates me constantly 🙂 So to turn off handoff, run the script below:

Enterprise operating systems for servers, are not chosen because they are liked. They are chosen because they survive stress.

Culture is not revealed by behaviour under control, but by motive under autonomy. Highly controlled environments mask intent and allow organisations to promote leaders whose inner compass has never been tested. When controls are later removed at seniority, behaviour shocks leadership and risk materialises.

It is a … Continue reading “Is Banking Complexity a Shared Destiny or Is It a Leadership Failure?”

1. The Organisation That Optimised for Distrust I once worked in a company with spectacularly low trust.

Clients were charged a small fortune for products that competitors could deliver at a fraction of the price. … Continue reading “Why Low Trust Organisations Confuse Control with Delivery”

Why do Companies Get Stability So Wrong? Most companies do not fail because they cannot innovate. They fail because they misjudge stability. Some organisations under invest. They chase features, growth, and deadlines while stability quietly drains away. Outages feel sudden. Incidents feel unfair. Leadership asks how this happened “out of nowhere”. Other organisations over invest. They build process on process, … Continue reading “Stability : The Water of Life for Engineering”

I have started writing production code again. Not prototypes. Not proofs of concept. Real systems. Real risk. Real consequences.

Why More Information Doesn’t Mean More Understanding We’ve all heard the mantra: data is the new oil. It’s become the rallying cry of digital transformation programmes, investor pitches, and boardroom strategy sessions.

Disaster recovery is one of the most comforting practices in enterprise technology and one of the least honest.

1. Backups Should Be Boring (and That Is the Point) Backups are boring. They should be boring. A backup system that generates excitement is usually signalling failure. The only time backups become interesting is when they are missing, and that interest level is lethal. Emergency bridges. Frozen change windows. Executive escalation. Media briefings. Regulatory apology letters. Engineers being asked questions … Continue reading “Why Rubrik’s Architecture Matters: When Restore, Not Backup, Is the Product”

1. Size Was Once Mistaken for Stability For most of modern banking history, stability was assumed to increase with size. The thinking was the bigger you are, the more you should care, the more resources you can apply to problems. Larger banks had more capital, more infrastructure, and more people. In a pre-cloud world, this assumption appeared reasonable. In practice, … Continue reading “Why Bigger Banks Were Historically More Fragile and Why Architecture Determines Resilience”
