Why agents are the new kingmakers https://t.co/vQcpSew4a3 #AI #ML #DL #NN #oss #opensource

Your PDF thumbnail step was a 9.8 RCE. Defensive AI found it before attackers did: https://t.co/3M5SiOLpps #infosec

"Can I bet my platform on this?" is what customers actually ask when asking for dates. Marty Cagan says the real trade-off is predictability vs outcomes, and a date today buys mediocre software on time: https://t.co/HCjFHvwtJF #Product

Errors are the attack vector. Make an agent's secure fetch fail and it runs attacker code. Trentina stops it. https://t.co/YL4DBGbyQT #AISecurity

[Scott McCarty @fatherlinux]

Vendors offering to pre-inject customizations into your container images sounds convenient, but you're trading sovereignty, agency, and security for ease. Keep it in your own CI/CD. https://t.co/d3dqRtZqGo

Open weights ≠ open source — but even the former OSI head says he'd take them. Anthropic is the one major AI company that didn't sign the open-weight coalition. Whose business model depends on proprietary winning? https://t.co/IZlq7Cyu0G #AI

[Scott McCarty @fatherlinux]

RHEL's MCP server now runs AI-generated commands with three guardrails: gatekeeper AI, human approval, systemd sandboxing. Not zero — three.

I use LLMs every day but hadn't dug into how Transformers actually work. This LWN comment thread on Debian's AI policy accidentally became the best education on token selection, temperature, and determinism I've found.

Got hacked twice in one month. AI helped the attackers chain CVEs into a sophisticated multi-stage breach. AI also helped me kick them out, patch, and harden — in 3-5 prompts, on work calls. The balance is tipping back. https://t.co/ahtpsau1La #infosec

Red Hat Hardened Images wins CloudX 2026 Best Innovation in Cloud Security. Security-first containers built on UBI. No bloat. Shorter CVE cycles.

Stef Walter and I introduced Fedora Hummingbird Linux at #RedHatSummit — a rolling-release Linux for Builders, built by a lights-out factory. Slides up. #RHEL #Fedora https://t.co/Pi9mA6Uaao

Slides from my #RedHatSummit RHEL roadmap session with Brian Stinson — building the next RHEL in the open. #RHEL #OpenSource https://t.co/SsU0HkWuE1

Fedora Hummingbird meeting July 23, 12:00 UTC — agenda is still forming, bring your ideas: https://t.co/K7mGCM6UaY #Fedora #Hummingbird

[Scott McCarty @fatherlinux]

Slides up from my #RedHatSummit talk with @jspaleta — the Fedora-to-RHEL pipeline and Innovation Lifecycle. #RHEL #Fedora https://t.co/EhMmiGaRsE

[Scott McCarty @fatherlinux]

Near-zero-CVE Java containers — one line change in pom.xml. Jib + Red Hat Hardened Images, no Dockerfile needed. Great walkthrough by @daboroscode.

#Hummingbird

[Scott McCarty @fatherlinux]

Anthropic builds frontier AI but can't stop proxies reselling Claude at 90% off. Every new defense spawns a new evasion market. Best piece I've read on it:

GitHub Actions now supports RHEL 9 and RHEL 10 runner images. Build and test on the same OS you deploy to.

In 1377, Ragusa invented quarantine — ships anchored on islands for 30 days before entering the city. They called it Trentina. MCP-Airlock is now Trentina: same three-layer defense for AI agents, better name. https://t.co/j2gAvDTK4j

[Scott McCarty @fatherlinux]

Most Linux desktops: police & fire QA. Bluefin built a dark factory — 255 tests, real VMs, agents that write regression tests from bug reports.
