Today I Learned
What did you learn today? Share it with us!
We learn something new every day. This is a community dedicated to informing each other and helping to spread knowledge.
The rules for posting and commenting, besides the rules defined here for lemmy.world, are as follows:
Rules (interactive)
Rule 1- All posts must begin with TIL. Linking to a source of info is optional, but highly recommended as it helps to spark discussion.
** Posts must be about an actual fact that you have learned, but it doesn't matter if you learned it today. See Rule 6 for all exceptions.**
Rule 2- Your post subject cannot be illegal or NSFW material.
Your post subject cannot be illegal or NSFW material. You will be warned first, banned second.
Rule 3- Do not seek mental, medical and professional help here.
Do not seek mental, medical and professional help here. Breaking this rule will not get you or your post removed, but it will put you at risk, and possibly in danger.
Rule 4- No self promotion or upvote-farming of any kind.
That's it.
Rule 5- No baiting or sealioning or promoting an agenda.
Posts and comments which, instead of being of an innocuous nature, are specifically intended (based on reports and in the opinion of our crack moderation team) to bait users into ideological wars on charged political topics will be removed and the authors warned - or banned - depending on severity.
Rule 6- Regarding non-TIL posts.
Provided it is about the community itself, you may post non-TIL posts using the [META] tag on your post title.
Rule 7- You can't harass or disturb other members.
If you vocally harass or discriminate against any individual member, you will be removed.
Likewise, if you are a member, sympathiser or a resemblant of a movement that is known to largely hate, mock, discriminate against, and/or want to take lives of a group of people, and you were provably vocal about your hate, then you will be banned on sight.
For further explanation, clarification and feedback about this rule, you may follow this link.
Rule 8- All comments should try to stay relevant to their parent content.
Rule 9- Reposts from other platforms are not allowed.
Let everyone have their own content.
Rule 10- Majority of bots aren't allowed to participate here.

You know, a piece of black tape would've been a lot easier.
Or if computer manufacturers just put in a hardware disconnect for the camera and mic. Like Lenovo used to do with the wifi switch.
That wont help with recording the audio from the mic
Hardware manufactures could (and should) put separate mic and cam LEDs wired directly in line with (wire in parallel to)the power circuits for the mic and camera. They won't, but they should. Best they ever do is a digitally controlled LED that is sketchy as fuck, for the camera only.
Framework does. Switches for the mic and camera both electrically disconnect the devices: https://community.frame.work/t/the-1080p-webcam/157
It's a bit more expensive, because a pure electrical switch wouldn't age well and you'd get bad connections sometimes. They implemented an optical switch that does the same job. That's probably whole pennies per unit more expensive, and ain't HP got time for that.
That's actually really cool. Framework will likely be my next laptop.
