For anyone that missed it, this version was cooked up in Photoshop. But an actual version does exist
- Comment on What do I need to know about the Odyssey before watching the film? 3 weeks ago:
Looked into going to the closest one near me, at €32 per ticket every showing was sold out for at least a week. But I’ve never had the full IMAX experience before.
I think I’d be willing to pay double the regular ticket price to try it out for once but full theaters can be a genuine dealbreaker.

- Comment on What is negative voltage? 4 weeks ago:
Not much actually, normal line out levels. Definitely cooked the mic though! The sound was like if you dropped earbuds at half volume, you heard just enough to know something is there
- Comment on What is negative voltage? 4 weeks ago:
No worries! I did blow out a microphone this way, plugged it in an out- instead of an input and only realised my mistake when I heard faint music through the microphone
- Comment on What is negative voltage? 4 weeks ago:
Thats the sidenote on my previous comment!
- Comment on What is negative voltage? 4 weeks ago:
Oh for sure, there’s a famous quote that goes along the lines of “Technology at a certain point to the average person is indistinguishable from magic”
we have electromagnets inside the speaker that can alternate between the two potentials at the same frequency/speed as is required for the tone in question?
Right on the money! For subwoofers they’re huge cones and huge magnets (I LOVE the pressure of an 18" super scooper), those go at 15-150 times a second back and forth. For your phone speakers or earphones they’ve the tiniest membranes that go at 200-18000 times per second. A quality soundsystem will combine these to get a range from 20-22000Hz which is a little more than our ears ability.
- Comment on What is negative voltage? 4 weeks ago:
You’re welcome! As long as the cone is in its rest position there’s no energy so no current which means (according to Ohms law) that the amplifier at this point is acting as an infinite resistor.
Sound is then created by continuously moving between the -12v and +12v, if you connect just +12v to a speaker the cone will just stick out once and remain there, not much of a sound is it. Sound is a complicated alternating waveform.
Sidenote: this is a physicists rabbithole, magnets moving around in coiled windings will create its own electrical signal. So if you talk into any speaker you can make it act as a microphone and record. So be careful with oversimplifications!
- Comment on What is negative voltage? 4 weeks ago:
I don’t think anyone referenced audio applications yet, the concept might be easier to grasp if you visualise it with a speaker.
Sound is just a particular way of moving the air, so a speaker at rest is just a cone sitting in the middle of an electromagnet, not protruding, just resting ready to be pushed out or pulled in according to the desired sound, this is the ‘rest’ state, or 0v.
Amplifiers are provided with a positive voltage to be able to pull the speaker cone one way, and a negative to push out the other way, with a reference (or ‘rest’) in the middle. This voltage, often +12v 0v -12v, is provided be a transformer that has been tapped in the middle. But if you use measure accross the tranformer, you will measure +24v, because that’s the total voltage potential of the circuit.
If you switch your measuring probes the other way around you’ll see -24v on your meter, did anything fundamentally change when you measured the other way around? No! It’s just your reference point that changed.

- Comment on [deleted] 2 months ago:
Imma have to disagree on that one, I find discussion here on par with early reddit days. The good and the bad included. Although the internet in general has radicalised tenfold since those days.
- Comment on [deleted] 2 months ago:
I’d go back to the actually good reddit days, oh wait were there right now on lemmy
- Comment on Has anyone else noticed the strong pro CCP and anti-west vibes here? 2 months ago:
I’m sorry but not one part of your comment shows any problem with lemmy. We’re using federated social media specifically so any instance/community can exist is a vacuum, and that includes those you do not agree with.
There are plenty of comms not having anything to do with politics that thrive, politically loaded content does slip into my feed and discussion is rarely uncivilised - on par with early reddit days.
lemmy failed as a platform
This is exactly my problem, you think lemmy is one platform. It is not. It’s interconnected but seperate bubbles of activity that are brought together by federation, which has always been optional.
- Comment on Has anyone else noticed the strong pro CCP and anti-west vibes here? 2 months ago:
I’ve yet to see this impact the rest of lemmy when a simple defederation is sufficient.
- Comment on Has anyone else noticed the strong pro CCP and anti-west vibes here? 2 months ago:
I get it, it’s just not a good enough reference for a Lemmy-wide issue. Reddit had MAGA and die hard conservative communities, but they stay isolated; just as I’m seeing here on Lemmy. On Reddit they had brigading issues periodically, just as on Lemmy, you can just defederate on instance or user basis and problem solved.
- Comment on Has anyone else noticed the strong pro CCP and anti-west vibes here? 2 months ago:
Judging by active users, lemmy.world is the default, .ml isn’t even top 3. I’m getting pretty tired of people referring to Lemmy as a single platform while it’s entire purpose is to have a decentralized network where federation is always optional.
- Comment on Has anyone else noticed the strong pro CCP and anti-west vibes here? 2 months ago:
I went to lemmygrad to view the user, I know about the defederation
- Comment on Has anyone else noticed the strong pro CCP and anti-west vibes here? 2 months ago:
I went to their instance but only found a single post?
- Comment on Has anyone else noticed the strong pro CCP and anti-west vibes here? 2 months ago:
I keep reading about this, can you show me some examples of pro-CCP sentiment? Tbf I block political communities anyway but I’m curious what tankie behaviour people keep referring too.
- Comment on Has anyone else noticed the strong pro CCP and anti-west vibes here? 2 months ago:
Has the political stance of the devs ever impacted lemmy in any way? From what I can tell they do a pretty good job isolating their views to their instance. Honestly apart from a few comments I rarely see any tankies.

Following your upbringing is as reasonable as it gets. Going against what you believe isn’t just happening because you followed someone else’s reasoning, it’s something you navigate by yourself over a period of time.

Amen, I’m in the EU and only saw real statistics in college. Tbf propaganda in itself needs to be understood and thought better in general
- Comment on Differences of Opinion by Wendy Cope 2 months ago:
I’ve been in that situation countless times, I can tell you people want to believe the scientific method works but there’s always a reason they don’t. Here’s a few reasons I’ve encountered:
-
Eroding trust in institutions: they don’t trust the organisations or the people doing the studies. IMO news cycles play a big role in this; a study with a catchy result “A glass of wine a day is actually good for you” - by itself already a misrepresentation of the results - gets all the headlines. The countless of studies that prove no amount is good for you doesn’t get any.
-
They believe science is a book of solid answers, while it’s merely a methodology to find better answers. People have a hard time accepting this.
-
Post-information age: every bit of human knowledge at our fingertips is a true monkey’s paw. A real overload of information has people exhausted, they rather listen to someone like them than have big words thrown at them by scientists.
-
Misrepresentation of data: I cannot stress enough how easy it is to misrepresent data. Without proper context any piece of data can be framed to fit a narrative. Studying statistics was so counter intuitive, you’ll never be able to convince people going on instinct.
Honing in on where people get stuck can help you get through to them. I know this will sound corny, but if you talk to people from person to person, not being judgemental, and really try to listen, there’s always room for change.

“You can’t reason a person out of a situation they didn’t use reason for to begin with” is a lesson everyone learns eventually…
