Decision-changing for sandboxing, dependency installs, and build isolation.

Worth mentioning

1.
A Network Allow-List Won't Stop Exfiltration
Decision-changing for sandboxing, dependency installs, and build isolation.
Domain allow-lists do not prevent exfiltration of secrets through allowed channels; an egress proxy + DLP scanning can close the gap.

2.
“Long-Term Support” doesn’t mean what you think
Avoids a common planning trap in ops and dev environments.
LTS is a promise of security/maintenance updates over a time window, not a guarantee of fewer bugs or new features.

3.
Debian SE Linux and PinTheft
Practical reminder that “optional” hardening can stop real exploit chains.
SELinux strict mode blocked the PinTheft exploit in Debian testing; exploit succeeded after loading rds module in unconfined context.

Greg Brockman: Inside the 72 Hours That Almost Killed OpenAI
Worth consuming later for context if you depend on OpenAI, but not decision-grade today.
Podcast episode page claims an inside account of the Altman firing window and notes OpenAI product/process topics, but transcript is gated.
⚠ Uncertainty: Transcript is member-gated; only teaser text was readable.
