Yes, in digital logic, ones and zeros are almost always represented as LOW (negative pole of power supply) and HIGH (positive pole of power supply), such as 0 V and 3.3 V, referenced to ground. This is based on properties of both bipolar and CMOS transistors, fundamental logic elements, where zero base-emitter current or zero gate-source voltage means they're non-conductive (I hate using open/closed for obvious reasons). However, high-speed and/or long-distance communication pretty much requires differential signalling, which is pure AC measuring between the two conductors. (Just compare SCART (coaxial analog baseband signal, RGB+bidirectional composite SD A/V) and DP or HDMI (shielded twisted digital differential pairs, unidirectional 4k+ A/V) cables by thickness and bandwidth.) And much like sound, radio waves can only be AC.

A piano/guitar string is plucked and then vibrates at its own natural frequency (plus in practice, higher modes aka harmonics/overtones defined by where it's plucked and mechanical design). Wind instruments are designed to create continuous oscillation from constant flow of air by amplifying reflected waves with incoming air pressure energy (blowing straight into a cylinder won't work, hence the weird pipe shapes, holes and reeds). Either way, they resonate at their design frequency. So do self-oscillating piezo buzzers. The speaker membrane, ideally, does not have a resonant frequency (responds equally to disturbances at any frequency between 20 Hz and 20 kHz) and needs to be pushed constantly to create sound. Like the membrane of a mechanical phonograph/turntable, the shape of the wave it should create is delivered to it in real time, except electromagnetically. That's why player pianos need very little data (literal punch cards: one bit per beat and string (ignoring dynamics), so up to about 240 × 88 ≈ 2.6 kB per minute, uncompressed) to reproduce entire songs as opposed to audio recordings that require samples at decent precision (16 bits is generally good enough) at at least 2x the highest frequency to be reproduced (about 5 MB/min for one CD-quality channel, uncompressed).

Yup. When you add an electron to one end of a wire, the change in the electric field will be felt very quickly (high percentage of light speed) across the wire and the electrons, now outnumbering protons, will repulse and want to shed the extra one from any point in the wire.

Like when you add an atom to a sealed gas container.

I could add to this analogy. Yes, the wind passes from a high-pressure point to a low-pressure one but that's just direct current. The weather can change, reversing the wind every few minutes (alternating current) and you can still harvest it with a turbine (for example, a lightbulb filament or heater lights up in either polarity) but it wouldn't help a ship with a basic sail travel to a destination (much like DC motors, it would change direction when polarity is reversed). And then there's sound, akin to very quick polarity changes where particles never travel very far. It doesn't carry much energy but the waves travel faster than wind and can be modulated with a signal to carry information. Both wired and wireless electronic communication is kind of like that. (Except wireless is decoupled from the charged particles that create the waves, the disturbances in E and B fields propagate on their own without matter)

There's a HUGE number of electrons in everything with a massive total negative electric charge but almost exactly balanced by protons. That's why electrons move very slowly in a conductor but still transmit lots of current (electric charge over time).

Accumulating charge in a place is what charging a capacitor or battery is, it creates voltage (potential difference). Charges in an electric field store energy but also their presence/absence can represent data (DRAM and flash memory) and the field has various effects we can use, such as deflecting the beam in a CRT oscilloscope or controlling a stronger flow of electrons in a vacuum tube (valve) or field-effect transistor.

And the current also creates magnetic field with some similar effects (deflecting the beam in a TV CRT) and some different ones (attracting magnets in a motor, inducing current in a transformer's secondary winding).

Plus, both fields can oscillate at a vast range of freequencies and travel in waves, making radio, microwave ovens, vision, UV sterilization, X-ray machines etc. possible (although each of these applications uses the properties of EM waves at specific frequencies differently).

Which Czechoslovakia? The states over its history were quite different.

  • First Czechoslovak Republic (1918-1938)
    • Declared as Austria-Hungary fell apart at the end of WWI.
    • Industrial powerhouse dismantling Austro-Hungarian power structures, investment in modernizing rural Slovakia
    • Some people see the creation of this state as attempts of entitled Czechs to legitimize their country stretching far east but Slovaks were not organized as a nation before this point so joining Czechs was their best option (days before Czechoslovakia was declared in Prague, the few Slovak intellectuals who knew about their nation's extent and situation reached this consensus and informed the Prague AH-separatists in a letter). Frankly, the inclusion of German-populated Sudentenland (establishing historic Bohemian, rather than ethnical borders), Transcarpathia and Upper Hungary were way more problematic, not to mention Trans-Olza, settled in a minor war with Poland over Cieszyn Silesia They do have a minor point: the prevalent push towards "Czechoslovak" national identity as opposed to accepting CSR as a country of Czech and Slovak (and Ruthenian, plus Hungarian and increasingly problematic German) nationals (some were even trying to classify Slovak as a Czech dialect) was ignoring many ethnical differences, and Slovakia only got represented on the flag as it changed from the not helpful Poland🇵🇱-with-slightly-more-contrast to still-controversially-used-today-🇨🇿 in 1920.
  • Second Czechoslovak Republic (1938-1939)
    • Beaten into submission by superpowers signing the Munich agreement that was supposed to appease Nazi Germany but nobody believed that would hold. Prior to the agreement, Czechoslovakia could likely defend itself long enough for Allies to come but didn't want to start a war that Chamberlain insisted wasn't inevitable.
  • Protectorate of Bohemia & Moravia + Slovak Staat (1939-1945)
    • Two Nazi puppet states, not actually called Czechoslovakia. Created after Czechoslovakia, weakened by the Sudetenland loss and other Munich Agreement consessions, plus flanked by the now-annexed Austria, surrendered to Nazi Germany in exchange for not being bombed.
    • The democratic government fled to London and helped organize dissent via radio & sent elite paratroopers to sabotage the arms industry and assasinate the Protector
  • Third Czechoslovak Republic (1945-1948)
    • Created after the Prague Uprising and liberation by Soviets (most territory) and Americans (West Bohemia)
    • Struggling to restore democracy with the Soviet-puppeted Communist Party's influence
    • Controversial expulsion of Germans that was a humanitarian disaster and a massive brain drain
  • Czechoslovak Socialist Republic (1948-1989)
    • After Communists gained majority vote, they did a coup d'etat and Czechoslovakia became a Soviet puppet state.
    • Collectivization and Stalinist purges in the 50s, hopes of democratization in 1968 crushed by Soviet invasion (the only success was that Slovaks gained more independence and CSSR became a federation because the Soviets didn't care), largely passive submission until Gorbachev (1988) but moderate living standards increase in the 70s and 80s
  • Czech and Slovak Federative Republic (1990-1992)
    • After the Berlin Wall fell, it was obvious the Soviet sphere of influence wouldn't hold so on the next protest opportunity (legal marches on 1989-11-17, 50th anniversary of protests for a Nazi-assasinated student), dissent members spoke out and a general strike was announced; police beat some protesters but nobody died, hence "Velvet Revolution"
    • Democracy, unrestricted import of foreign goods & media and wild privatization started, people could get rich or poor overnight as the economy turned inside out
  • Czech Republic + Slovakia (1993-present)
    • Created after Slovak politicians wanted more independence and everybody was just trying to comprehend the market changes so nobody really complained and a no-fault divorce was scheduled on 1993-01-01
    • The countries have a brotherly relationship but went their own ways and it's clear there will most likely never be a Czechoslovakia again

sections of strictly increasing or decreasing vertical/horizontal ratios

That's correct but I don't think there is any place where this rule has been broken except for the ㇓ section (no progression of ratios on a convex curve allows for 1:1 between long stretches of 2:1 and 1:0). And at this resolution, in-between ratios like 2:3 (alternating 1:2, 1:1) are viable, dare I say necessary? It's a kind of dithering, a technique well-known among colors but less so among shapes. Sometimes you need a slope between the two...

The right side could use some 1:3 bits like on the left and shorter 1:0 (orthogonal) and 1:1 (diagonal) sections but this is still plausible.

the back of the dimple on the apple seems a bit too open (?)

Yes. The way I would say it is that the part behind the stem ends too sharply (extend the ⠗ pink part's tip by 1-2 px to the right)

I just saw !germanrap@feddit.de as #6 in Communities/All (sorted by Hot) (web archive) on feddit.org. This feels weird because the feddit.de server has been down for almost 2 years and the community seems to have no content (the home server cannot be contacted to verify but no posts seem to have been federated to other popular instances like feddit.org) and obviously never will have. As for the subscriber count, feddit.org keeps its own tally, which is currently (archive) at 64. This does not include new subscribers after the last federation with feddit.de, except local ones. These can also be checked separately, and the number is... one. This suggests that only one person ever subscribed to !germanrap@feddit.de in the past 1.5 years (as far as feddit.org, a 1k-weekly-active-user instance, is concerned), and yet the community is very high in Hot for a day.

Obviously, the visibility of the Communities/All (by Hot) list varies by client, for example Voyager shows it unsolicited as "Trending communities" in the Search pane, and even though Lemmy devs didn't include it prominently in default Lemmy UI, they definitely have considered the value of this list in mind since it's made the shortlist in Lemmy's API benchmarks.

It's probably okay, it can walk and fly.

I tried giving it some bread but it wasn't paying any attention to it. I shoved it closer, which scared the poor guy and it flew on a first floor windowsill across the street. That's probably for the best, it could easily fall victim to a dog otherwise. I threw the bread up there but it seemed tired from the flight and sat in the shade. Most of the bread was gone the next day, and so was the pigeon.

I was really surprised by how long the young ones' beaks are, I first thought it could be a corvid.

Eggcorns (Wikipedia / YouTube video by RobWords) are language mistakes that sometimes take over and change the spelling and perhaps even the meaning of a word. This is rare in German because there's fewer homophones but in this episode of Wort der Woche, DW explains how "munttot" became "mundtot". Available as audio or transcript.

Yup, this is real, recorded 15 minutes before the new year.

Also see our top-of-the-2010s Christmas song Půlnoční, whose music video features the building on midnight of New Year's. Since I was there shortly before that time, I told all people willing to listen.

Yup, it's real. How did it get into production with

  • a flattened back tire with central hub very off-center,
  • right pedal on the left side, and very far below the cyclist's leg,
  • chain routing defying common sense,
  • and a disjointed left glass?

At least the socks seem to be classic low-res stitch art likely by humans...

WebP does everything GIF did, just better. The only problem is adoption. Maybe a similar, single-syllable name could have helped.

  • Ends the pronunciation debate: hard G in the 1987 filetype, soft G in the 2010 one
  • Looping soundless video gets a name that's short and does not refer to a terribly inefficient format (that "gif" sharing sites often no longer use anyway), plus some wrong people have been using it already
  • Software peer-pressured into supporting it (nobody wants to hear "they don't support JIF" about their software)

They say lab is short for German Labor, which is short for Romanian laborator, which is short for Latin laboratorium.

...and paper that says "Enjoy the rust, swasticar" on the windshield

Seen in Prague-Karlín, about 30 m away from that other mildly vandalized vehicle. Looking up the licence plate, the owner's full name seems to be Igor Norton Tesla Slovák and it's the first Cybertruck in the country, so he must have spent lots of money importing it and modding it (and bribing officials?) to pass registration.

Yes, Prague is inexplicably car-brained for how dense the public transport network is.
