RAMmageddon – DigitalWasteland

In March 2026, Google's TurboQuant cut the memory needs of AI models by a factor of six – proof, for Jens, that smarter software beats more hardware. Meanwhile memory prices kept breaking records, and Europe's Chips Act...

A detour from the hardware crisis: Jens built a personal AI coaching app, JK-Fitt, mostly with Claude Code – and learned his biggest lesson from a single component, the coach's system prompt. His first version was...

"We understand that we should modernize. But where do we start?" In Part 4, Jens answers the question he kept hearing from CTOs, IT leaders and even a CFO. Classic sizing tools only ask which box fits the refresh. The...

"Got it, but where do we start?" After Part 4, that was the question Jens heard most. Part 5 is his answer: a map of seven patterns that show up in almost every mid-sized data center once you know what to look for, each...

In Part 1 of the series, Jens wrote about a crisis. In Part 6 he takes that word back: a crisis ends, but what the memory market is going through in 2026 is a structural reset. He lays out the evidence, explains why...

A thesis is only worth as much as the calculation that carries it. In this deep dive, Jens takes a synthetic, fully disclosed reference model of a mid-sized data center and calculates what happens when 80 VMs are...

Using an anonymized, archetypal mid-sized machine builder, Jens shows why AI initiatives in the mid-market rarely fail because of the models, and almost always because of the data architecture. He proposes a lakehouse...

In many environments, the most expensive part of a database server isn't the hardware, it's the SQL Server license that comes due every year. Jens explains how dozens of small, barely used SQL VMs, wrong editions and...

Modern software protects itself; older software relies on the infrastructure to protect it. In this short episode, Jens explains why that one difference decides what your hardware has to look like, and why it gets...

On July 1, 2026, IBM raised prices on FlashSystem by 40 percent and on Power servers by 17 percent. For Jens, that was the moment the memory crisis moved from a procurement question to the incoming invoices. In this...

Kubrick's black monolith is now on your kitchen table. It's green, nine centimeters tall, and called DDR5. In July 2026, the memory crisis left the data center and showed up as a price tag for everyone who owns a...

In Frank Herbert's Dune, it's not price that decides who gets Spice, but allocation. In August 2026, according to an unconfirmed DigiTimes report, the big memory makers had already fully allocated their DRAM and HBM...

Five good fitness apps, five silos, five foreign assumptions about how Jens should train. So he built IDUN, a personal AI coach for training, nutrition, recovery and longevity, with Claude Code and the Claude API...

Three weeks after introducing IDUN, his personal AI fitness coach, Jens deleted a working part of it: the Yazio integration, replaced in four days by his own nutrition module. A well-tested training model turned out to...

Jens Klasen has joined Everpure (formerly Pure Storage) as a Cloud Native Architect, on the team around Portworx – and he explains why. Four open flanks at once – hardware, virtualization, container platform and cloud –...
