The "Lift-and-Shift to KVM" Fallacy

The "Lift-and-Shift to KVM" Fallacy

The VM conversion completed without errors. Every workload made it across. The migration dashboard showed green, the project lead closed the ticket, and the consultants left the building. Three weeks later, backup verification jobs are silently failing. Monitoring dashboards are dark. The on-call team is operating without baselines. Nobody knows what normal looks like on the new platform. The V...

I built a CLI that tells you where your Kubernetes money burns

Got tired of setting up dashboards just to answer "where does our K8s money go?" So I built Burn — a CLI that shows you exactly which namespaces, pods, and load balancers cost what. One command, no agent, no dashboard. ## What it looks like $ burn analyze --prometheus http://prometheus:9090 NAMESPACE ...

Perl 🐪 Weekly #771 - Exploring Perl Modules

Originally published at Perl Weekly 771 Hi there, I put the 'Testing in Perl' course on hold for now. Instead of that we are going to explore the use of some of the mocking libraries we saw during the course. In the next session we'll pick one of the Perl modules used for mocking and we'll look for modules that use it. We'll try to understand how it is being used and we'll try to contribute some...

ATLSECCON 2026: Context, Identity, and Restraint in Modern Security

Harbor cities understand accumulated risk. Cargo moves in quietly. Weather shifts by degrees. One bad assumption can sit unnoticed until it reaches critical mass. Halifax has lived with that kind of memory for more than a century. On December 6, 1917, a collision in Halifax Harbor triggered the largest man-made explosion prior to the atomic bomb, a disaster that directly changed the lives of over ...

POV: The Laptop Says "No OS Found" but You’re a Value Architect💅✨

In a fast-paced logistics hub, a Blue Screen of Death (BSOD) isn't just a technical glitch; it’s a killer vibe for the whole workflow. I recently had a user come to me with the ultimate jump-scare: their laptop crashed, rebooted, and hit them with: "No Bootable Device — Please download and install an operating system." 💀 To most people, that screen means "your files are gone." But as a Value Ar...

Best Email API in 2026: An Engineer's Honest Comparison

Why this list is different The "best" email API depends entirely on what you're building. A side project optimizing for the free tier needs different things than a Series B SaaS sending two million transactional emails a month. This post grades eight providers against the criteria that actually move the needle in production, and tells you which one to pick for which use case. Most roun...

GBase 8a QUALIFY Clause: Filtering Window Functions the Smart Way

When you use window functions in SQL, you can't filter their results directly in a WHERE or HAVING clause — that's a well‑known limitation across many databases. GBase 8a, the China‑domestically developed MPP database from GBASE, solves this elegantly with the QUALIFY clause. Let's break down how it works, what it can do, and where you need to be careful. Sample Table DROP TABLE IF ...

I Spent 3 Years Looking for This Tool. It Didn't Exist. So I Built It.

Every time we hired a new developer, the same nightmare started. Week 1: "Alex, how does this service work?" Week 2: "Alex, where does this connect to?" Week 3: still pulling me and my senior devs away from real work. I managed a team building software across multiple projects — Java backends, ESP32 firmware in C/C++, frontend apps. The codebase was real, complex, and completely undocumented in ...

I Built an AI Tool That Turns Raw Ideas & Notes Into Platform-Ready Posts (X, LinkedIn, Threads)

For the longest time, I was the classic "builder who doesn't ship content." I'd ship features, take notes, have insights... but turning them into consistent posts on X, LinkedIn, or Threads? That part always felt like a chore. The context switching, reformatting, trying to sound natural on every platform — it killed my momentum. So I built Elevenwritt. What it actually does You paste...

Failover Sounds Good… Until It Doesn’t Work

“We have failover.” That sounds reassuring. But when real failure hits… many systems still go down — hard. Why? Because failover is easy to configure — but extremely hard to make reliable at global scale. Here are the most common ways failover fails in production: ❌ 1. Failover That Was Never Tested RDS Multi-AZ enabled Kubernetes failover configured Looks good on paper. Re...

Flutter Navigation Made Simple: Moving Between Screens Without the Confusion

Navigation is one of those things in Flutter that looks simple… until it isn’t. At first, pushing a screen feels straightforward. But as your app grows — multiple flows, authentication states, nested routes — things start getting messy. Back stacks behave unexpectedly, screens duplicate, and users land in places they shouldn’t. We’ve been there. So in this guide, we’re breaking down Flutter nav...

UCP Requirements: What Your Store Needs Before Going Live

What do you need for UCP? There are two levels of UCP readiness. The first is the minimum viable manifest — the bare requirements to pass validation and appear in the UCP directory. The second is the agent-ready setup — what it actually takes for an AI agent to browse, cart, and check out at your store without friction. Think of this as your UCP checklist — the minimum requirements plus the recom...
