Using SCP on a Custom Port (and Avoiding the -p vs -P Mix-Up)

·4 views

If SSH listens on a nonstandard port, SCP needs to connect to that same port. The easy-to-miss detail is capitalization: use uppercase -P with scp, not lowercase -p. SCP doesn't have a separate network port. It connects through SSH, which uses TCP port 22 by default. If a server's SSH service listens on port 2222, SCP must connect to 2222 too.

Polling SMS OTP Delivery Status Without Webhooks (A Clinical Report Gate)

The page says SMS OTP delivery is failing. On-call opens the alert and sees a rise in codes that users requested but never verified, while a patient is waiting to complete login and receive a generated clinical report by email. Polling delivery status without webhooks looks like the direct response, but polling every message until a terminal state is the wrong default. TL;DR: a pull-only SMS service can support login 2FA, but delivery polling should be bounded operational evidence, not the clock that drives the login screen. Start the resend countdown when the send request is accepted, let the

The SI Wealth Transfer Is Becoming the Largest Rug Pull in History.

We are involved in this machine; don’t get upset by this message. Look at what you can do to make things more “evenly distributed”.

The deeper question is who will own the infrastructure, who will control access to it, who will receive the wealth it creates, and what happens to the people whose work makes the system valuable. SI is often described as an open revolution.

Your AI agent doesn't need fewer permissions. It needs a mission.

If you've been on dev Twitter or Hacker News this month, you've seen the stories. An agent asked to clean up a folder deletes tens of thousands of files. A coding agent launches hundreds of parallel runs nobody asked for and burns through a five-figure bill. Someone's OpenClaw setup emails their clients without approval. Someone else writes "never touch production" in CLAUDE.md, and the agent reads every secret in the .env anyway.

The September 2026 KEV wave as an operations dataset, not a news cycle

The September 2026 KEV wave as an operations dataset, not a news cycle A single exploited vulnerability is an incident. Eleven additions to the CISA Known Exploited Vulnerabilities catalog inside one week is a pattern, and the pattern is more useful than any individual entry. Reading the late September 2026 batch together shows where attackers concentrate effort and where defender effort is spent badly. The late September additions include edge remote-access appliances, management planes and a popular web framework. Citrix NetScaler ADC and Gateway contributed two entries, CVE-2026-88771 and C
