  • The HDMI input does not need to be active for DDC/CI control.

    For example, a Raspberry Pi connected over HDMI can send commands even when its input isn’t currently displayed. It can change anything the monitor exposes through DDC/CI, from switching the USB KVM and configuring PBP/PIP to adjusting brightness and volume.

    HDMI effectively becomes a limited out-of-band control path, opening up some interesting automation possibilities.

  • To be able to unlock a FileVault-protected Mac over SSH after rebooting, first complete one successful SSH login while a user is logged in locally at the Mac.

    Apple’s published requirements do not mention this step, but preboot SSH may not work without it.

  • AI does more than automate work. It changes how much organizations need people’s cooperation.

    In the past, when someone refused to participate, the work often stopped. The organization had to understand the objection, negotiate responsibility, or address the underlying conflict.

    With AI, an organization can increasingly work around that person—reconstructing their knowledge from documents, producing the missing analysis, and continuing without them.

    This can make disengaged employees less influential. But the grimmer reality is that it also makes legitimate resistance easier to ignore.

    An employee may be raising concerns about unfair blame, unsafe decisions, burnout, or bad leadership. Instead of confronting those concerns, the organization can use AI to bypass the person and complete the task anyway.

    The result may look like greater efficiency while weakening people’s ability to be heard. Once an organization no longer needs your cooperation, it becomes much easier to ignore your objection.
