QR codes can have arbitrary looks even without dirty tricks (abusing the error correction to add a logo or taking advantage of central sampling to color all but the middle 3x3 square of each data pixel) but boy, is it hard.

It is designed to especially penalize ⬜⬛⬜⬛⬛⬛⬜, which is a part of the finder pattern (big squares in the corners) and the swastika.

I get it. Having a super secure browser installed on a government-issued work device likely raises suspiscion. Use Tails on your own machine.

To make you check and rickroll you indirectly. Iťs an edited screenshot, you don’t see metadata of unavailable videos

fediversesearch.com another site uses a similar Google trick but instead of a specific domain, it filters by footer text that appears in the default Lemmy UI such as “Modlog”.

Our family PC has one family user.

Why photograph with a polarizing lens for a catalog? It reveals impurities.

In the 90s, March did start with a Monday in '93 (ruled out due to Start button and Windows key) and '99. But it’s unlikely you’d see TV static (with a decently emulated camera shutter effect) behind an error dialog window - is it the desktop background?

West Bank, Gaza Strip, Terra nullius?

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

You can send a (salted?) hash of an email or its contents but that’s just a bit too complicated.

Those aren’t really accents. In many Slavic languages, the declination of verbs is gender-specific in the past tense and conditionals. The form is -l for masculine and -la for feminine. You can pronounce it -lǝ (emphasize the schwa that comes at the end of -l) to be vague about it, use the -lo neutrum (dehumanizing), or, to also sound sassy, one of the plural forms -li (default), -ly (all female or neutral, pronounced the same as -li) or -la (all neutral). Yeah, no good gender-neutral options yet.

Piezo buzzers have a resonant frequency they’re strongest at. Two-pin piezo disks need driving at the desired frequency. Usually only a GPIO pin (PWM-capable if possible) and a resistor is needed. Three-pin disks 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)

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.

ML or LM?

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

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
