Yes! The picture is inaccurate, people who need to learn ffmpeg rarely know they do.

- Comment on Do smoke detectors have little speakers inside them? If yes, would it be possible to hack them to play a little jingle? 3 days ago:
Piezo buzzers have a resonant frequency they’re strongest at. Two-pin piezo disks need driving at the desired frequency. Three-pin provide a phase-shifted feedback to the driving transistor to keep oscillating at the resonant frequency. Some include that whole circuit inside their housing so they have just 2 pins but those are for DC power, only the volume can be somewhat adjusted by changing the input voltage.

Which way is the rear? I tell that by the tag. (Yes, I add tags to clothing that doesn’t have them, except socks)
- Comment on 3 days ago:
With mods, it has been approved in the Czech Republic. Yes, our DOT is a joke and now even run by the Motorist party. A guy is offering to import one, apply the mods (front licence plate holder, amber rear blinkers, slight smoothing of edges) and get it registered.

Tracker? No, this is a copy of MATLAB '96 + Signal Processing Toolbox.

A Czech reporter’s name is Jan Tuna. Please keep saying “tuna fish” for his* sake.
* he/him, Jan is a common male name here derived from John, the female counterpart is Jana
- Comment on Home renovations 1 week ago:
I’ll be assuming the pole is not grounded (electrically isolated from Earth, the earth pin of sockets, radiators, plumbing etc.)
The difference is not DC vs AC but between it being connected across two screws, for which a high current source (hundreds of amps at negligible voltage) will heat the metal up - as opposed to connecting a voltage (like 120V mains for AC or 170V single-diode-rectified & smoothed mains for DC) referenced to ground to the pole. The former will draw a lot of current from the source through the screws and metal between them, heating it up. A car battery could briefly deliver hundreds of amps and several kW, making them glow red hot. The latter will create a potential between the pole and ground, which will only draw current when a load is connected between the pole and the ground. For AC, a person’s body’s capacitance to ground, even with insulating shoes, is enough to feel a tingle. For AC or DC of sufficient voltage (above 60 V), they will get a shock if they touch ground and the pole, completing the circuit.

And salty. Not good for robotic joints & electronics
- Comment on the news are so bad at reporting epstein files i wonder why 1 week ago:
If they don’t prosecute child sex criminals, we can’t expect borderline child casino operators to face consequences either. But Bobby Kotick (Activision CEO at the time) now has a scapegoat.
- Comment on Dogs welcome 1 week ago:
You are right but the field is not too far off, geologists should know where to obtain info on street lamps’ hellhound-proofness.
- Comment on the news are so bad at reporting epstein files i wonder why 1 week ago:
Everyone will be blaming Epstein for everything. Often justifiably, but that also takes away responsibility from people who can and should suffer consequences.

Is George a hint at the target audience (femboys)?
- Comment on Truly identical twins as actors would present really interesting opportunities for a stage play 1 week ago:
The book, Das doppelte Lottchen, is better, and I think it had been adapted too
- Comment on Dogs welcome 1 week ago:
They’re geologists, they should know if the lampposts outside are anchored sufficiently.
- Comment on Couldn't have said it better 2 weeks ago:
Did they get Playstation done and then just not release it? That’s what I meant.
- Comment on Couldn't have said it better 2 weeks ago:
Of course they’re going to release GTA 6 once it’s done, what else would they do?
- Comment on Save as PDF 2 weeks ago:
Similarly, Android has distinct “share” and “open with” menus but I mostly use the former as the latter.
- Comment on How does this thing work? (wrong answers only) 2 weeks ago:
Because it would go up to about 100 rpm and people at the store would know it performs poorly

Sometimes people on Lemmy rehost pictures because they notice the original’s domain (usually catbox.moe or the pict-rs media host of OP’s instance) is blocked by some ISPs

You have no idea
At least the biggest country to refuse 25 kV AC electrification is gone

I take one off and hop. Or throw a rug on the floor and shuffle.
- Comment on This is real. Big controversy regarding cheating in Olympic events because of the size of suit worn by jumpers 2 weeks ago:
The entire suit is 3D, in which case it makes more sense to talk about surface area, but that is measured in cm². The “circumference” must apply to the “sail” shadow.
- Comment on Anyone old enough to have used this before GPS? 2 weeks ago:
We don’t use nearly as many genericized trademarks where I’m from. I know that several publishers used this technique to make a road atlas of the Czech Republic in the 90s and 00s.
- Comment on This is real. Big controversy regarding cheating in Olympic events because of the size of suit worn by jumpers 2 weeks ago:
Um… That part is concave so adding material (area) decreases circumference.
- Comment on Anyone old enough to have used this before GPS? 2 weeks ago:
The most common ones were books that you’d flip east/west through, or skip to the indicated page for north/south, right?
- Comment on [deleted] 3 weeks ago:
Unfortunately, copyright is purposefully designed so that most works going into the public domain are irrelevant by then and nobody’s willing to convert them.

The wavelength has negligible effect on shadow geometry. What do you mean? Also, sunlight and daylight is pretty much the same thing.
