@jeffalyanak If you are a keyboard enthusiast you probably already follow @technomancy but I'd say they're the authority on custom keyboards in the fediverse.

@yogthos we were testing out CO2 sensors at work and logged readings at 5 minute intervals over a couple of days from one hooked up in a colleagues office (fairly large office but shared by 2 people and no windows).

The level varied by well over 100% as it cycled over the day. By 4pm it could peak in the vicinity of 2000ppm.

No wonder people are about ready to fall asleep in afternoon meetings.

I am sad that I couldn't make this month's #WeAreNameless but following the hash tag when I can for commentary has still been entertaining! Thanks everyone! :blobpats:

what is the "analogue loophole"? why do people say that removing the headphone jack would allow companies to restrict your ability to listen to music? (long, serious) Show more

the "analogue hole" refers to the idea that no matter how hard you try to make sure nobody can make illegal copies of videos, music, or text, there's always a "hole" in the protection that occurs when it's no longer digital. digital content can be protected - video files can be encrypted, music players can limit you to five devices - but analogue signals can't be. for example, itunes can disallow you from putting a song on more than five computers, but if you play the song through your speakers and record it, what you do with it is beyond apple's control.

one of the few remaining analogue outputs on a modern device is the audio jack. this is where you connect your headphones or speakers. your laptop only knows that something's plugged in. it doesn't know what's connected. you could be playing it through earphones or a massive speaker system and it wouldn't be able to tell. meanwhile, HDMI is a digital output format. it can tell if it's been plugged into a TV or a recording device, and can automatically disable output if you're recording it to make it harder for you to make copies of movies.

if the audio jack is replaced by USB-C or bluetooth, it becomes possible to tell what you're connecting to the laptop or phone. your phone might disable audio playback on anything but headphones to prevent you from hosting a public event with the music. it could also detect a recording device that you're using to (for example) make a copy of a song you're listening to on spotify and turn off the playback.

of course, at some point, digital needs to become analogue. humans can't watch electrical pulses, we need to see patterns of light. we can't listen to streams of 1s and 0s, we need vibrations in the air. this means that it's impossible to truly defeat the analogue hole - no matter what you do, someone can always just point a camera at their TV. it'll have worse quality, but it can never be stopped.

the analogue hole is one of many ways to circumvent DRM, or digital rights management. you can read more about it here: https://en.wikipedia.org/wiki/Analog_hole
