Grumpy old sysadmin, #Linux, #OpenSource. #privacy & #security fanatic.

Happily running Linux as my daily driver since 1992.

Happily rocking my fedora at #RedHat since 2013.

Very, very married....

I'm pleased to see two of my favorite tech companies, IBM and Threema, working together to get PQC protections into the Threema messaging app.

In IT, we often accept the "patching treadmill" as inevitable. But Red Hat’s Project Hummingbird is chasing the holy grail: a near-zero CVE reality.

By using minimal, image-based RHEL deployments, we can eliminate the "noise" of irrelevant vulnerabilities and focus on what matters. It’s about shrinking the attack surface by design, not just by reaction.

Chasing the holy grail: Why Red Hat’s Hummingbird project aims for "near zero" CVEs

Learn about Red Hat's Project Hummingbird, a solution designed to deliver minimal, hardened container images with a near zero CVE approach. Discover how it simplifies vulnerability management and enhances security for critical sectors.

Quantum computing offers huge leaps in tech, but also massive risks.

Full-scale quantum is still years away, but the threat is here now. Through "harvest now, decrypt later," bad actors are already capturing encrypted data to crack once the hardware catches up.

The time to prepare is today. Check out our latest blog to see how Red Hat is staying ahead of the curve and securing the post-quantum future:

From if to how: A year of post-quantum reality

For the last 5 years, post-quantum cryptography (PQC) has largely been discussed as a research topic.

OK this is the longest of long shots and will only mean anything to #irish folk or even #dublin (ers)…anyone got ANY idea where I could get my hands on photos of DART TRAIN INTERIORS FROM 1980’s?? Not finding anything much online. Building a paper diorama of a train carriage from this era for a film project. Any leads gratefully recieved! #train #rail

AI developer assistance is a game-changer. Which direction it changes your game in depends on a number of variables. My colleague Louis Imershein's series on Medium explains how to succeed with AI coding assistants on RHEL, focusing this installment on configuring Amazon Q Developer for RHEL.

Denmark Begins its Exit from Microsoft — and This is Just the Beginning

The move is part of a government-wide effort to reduce dependency on Microsoft software. The traffic department's move is just the beginning.

It's FOSS
