A look into Ubuntu Core 26: Deploying AI models on Renesas RZ/V series for production

Welcome to this blog series which explores innovative uses of Ubuntu Core. Throughout this series, Canonical’s Engineers will show what you can build with our releases, highlighting the features and tools available to you. In this blog, Asa Mirzaieva, engineer from the Silicon Alliances team, will show you how to deploy optimised AI models on Renesas RZ/V series hardware using the Dynamically Reconfigurable Processor for AI (DRP-AI).

The Silent Killer of IBM MQ: How One Leaky App Can Crash Your Entire Estate

A single leaky application can crash your entire IBM MQ estate by consuming OS resources through unclosed connections. Traditional monitoring misses these silent killers. Learn how proactive observability detects OPPROCS anomalies before they trigger infrastructure failures.

Apache ActiveMQ 5.19.7 and 6.2.6

On May 27, the Apache ActiveMQ project shipped two releases on the same day: 5.19.7 and 6.2.6. Look at the changelogs side by side and the story is clear — this isn’t a feature drop. It’s a coordinated security-hardening pass applied to both maintained branches of ActiveMQ Classic at once, with the same fixes deliberately backported so that no supported line is left behind.

Upgrading to ActiveMQ 5.19.7 or 6.2.6

The latest Apache ActiveMQ releases – 5.19.7 and 6.2.6, both from May 27 – are good releases to apply. They close known dependency CVEs and tighten the broker’s default posture. (We covered the full list of changes in our release overview.) But here’s the catch with any “secure-by-default” update: hardening defaults means turning things off.

Prevent container image overwrites with immutable tags in Bitbucket Packages

We’re excited to announce that immutable tags are now available for the Bitbucket Packages container registry. With immutable tags, workspace admins can set container image tags from being overwritten, moved, or modified after they’re first pushed.

Should platform, SRE, and security merge into one function?

Platform, SRE, and security are three distinct functions in modern engineering orgs, each shaped by a different problem. SRE was the operations function's answer to scale: how to keep systems reliable when the systems get big. Platform answered a different problem: how to let developers ship without becoming infrastructure experts. Security drew the line on what could safely reach production.

How to Build a Cost-Effective Log Retention Strategy

Nearly every home has that drawer or doom corner where you store all those items that you don’t need every day but that you still want to keep for those “just in case moments.” If you’re a document connoisseur, you may have financial documents that go back years because an accountant once warned you that an IRS audit would require seven years of back documentation. In short, you have a lot of documents that you may or may not need taking up a lot of room in your home.

The Connection Between Fast Tech Trends And Consumer Spending

A phone that felt advanced last year can suddenly seem outdated after one product launch. That shift happens quietly, quietly, although it influences how people spend money more than they often realize. Technology moves fast, and consumer habits tend to move alongside it. New releases appear constantly, upgrades are promoted heavily, and devices that still function perfectly well are replaced sooner than expected. A scroll-too-long-and-now-I-want-it moment has become part of everyday online behavior.

Why Your Company Should Be Paying for Your Tech Training (And How to Make the Case)

The conversation about upskilling tends to be framed as the employee's responsibility. Learn new skills. Stay relevant. Invest in yourself. The implicit assumption running beneath most of that advice is that the investment comes from the professional's own pocket, their own time, their own initiative, without necessarily expecting the organisation they work for to share any part of the burden.

The Overlooked Connection Between Recovery, Energy Levels, and Long-Term Performance

Many people believe better results come from working harder, training more, and staying productive at all times. While discipline and consistency matter, long-term performance depends on more than constant effort. Without proper recovery, the body and mind eventually slow down. Energy drops, focus weakens, sleep quality declines, and physical fatigue builds. This is why recovery should be treated as part of the process, not something optional.
