A "Showerthought" is a simple term used to describe the thoughts that pop into your head while you're doing everyday things like taking a shower, driving, or just daydreaming. The most popular seem to be lighthearted, clever little truths, hidden in daily life.
Here are some examples to inspire your own showerthoughts: 1
If you made it this far, showerthoughts is accepting new mods. This community is generally tame so its not a lot of work, but having a few more mods would help reports get addressed a little sooner.
Whats it like to be a mod? Reports just show up as messages in your Lemmy inbox, and if a different mod has already addressed the report the message goes away and you never worry about it.
The static on old CRT TVs with rabbit ears was the cosmic microwave background. No one in the last 25 years has ever seen it.
On a CRT? Sure, probably a lot haven't seen it. On a modern TV? Still possible for some - mine does this if I hit the channel button rather than volume accidentally.
Depending on the TV it's likely simulated noise at this point
That noise is horrible; why would someone simulate it rather than just show a blue screen?
I am doubting myself now after not being able to quickly find a verified source but I've worked with lots of smart TVs and seem to recall Samsung or LG models using this simulated effect. It would have had to have been simulated since there was no signal coming in, and I recall the pattern being noticably pseudo random.
As for why: I have no idea! Maybe just for user familiarity reasons, since a lot of people grew up with that kind of analog feedback that the antenna wasn't getting a signal.
Take what I said with a grain of salt, though, since like I said I wasn't able to quickly verify it. It's a vivid but ambiguous memory, though, since I also thought it was strange
This is exactly why. Preventing screen burn-in may be a tiny peripheral reason also, but providing a familiar experience to chronically myopic and cranky users (i.e. boomers) is probably the bigger one.
I found something about some recent-ish LG TVs having a default mode that shows static, but I couldn't find a clear answer on why, and the way to disable it is to enable "Cable DTV", which seems to suggest that it might actually be trying to get analogue signal by default...?
