As for data science using Python, something tells me that this has to do with memory heap capacities. I’m not sure about Python’s max memory heap, but Javascript through Node.js seems to have only 512MB. I’ve been using Node.js to deal with big datasets and my most recent experimentation stumbled across the need of loading 100 million numbers to the RAM: while my PC has a fair amount of physical RAM (12GB) and a great part of it was available, it’ll simply error when filling an array. I needed an additional parameter, --max-old-space-size, so Node.js could deal with such amount of data. I didn’t try the same task with Python because I’m used to Javascript (yet I’m done some things in Python), but I wonder how much memory can Python hold until an error like “out of memory” happens, because ML models (for example, those hosted and served in HuggingFace) loads training weights with dozens of GBs

historically we’ve been using AM at lower frequencies, and these travel further

While I agree with that statement…

AM doesn’t reach further than FM

… i disagree here. Yes it kinda does, and there’s why: FM deteriorates with phase shifting introduced by phenomena such as ionospheric reflection, while AM is more resilient to it because it encodes information as amplitude variations instead of frequency (and therefore, implicit phases) variations. Also, FM needs more bandwidth than AM. Also, the overlay of two or more simultaneous AM transmissions is “more understandable” than two or more simultaneous FM transmissions laying on the same frequency. Both the three are the reasons why the modern aviation continues to use AM for comm between TWR and airplanes, as an example. Not just by historical reasons, it’s because AM is more resilient than FM.

By “reaching further”, I don’t mean the range of propagation because, as you correctly said, it has more to do about wavelength and, therefore, the carrier frequency. By “reaching further”, I actually mean the capability for the signal to be correctly demodulated and minimally understandable at the end. If a signal can propagate across hundreds of thousands of kilometers (for example, between Earth and the Moon), but it can’t be recognizable at the other point (because the phases are all messed up to the point of being unable to be demodulated), then the signal (as in the content to be transmitted/received) couldn’t really “reach further”.

Here goes an example: I live in Brazil, in the southeast. I was in Sao Paulo state (not the city) when I once managed to receive an English-spoken CB (Citizen Band, 11 meters, approx. 27MHz) transmission. Most of our neighboring countries are Spanish-speakers, the only nearest English-speaking country is Guyana (the nearest corner close to Jatapu River being 3,000 km from Sao Paulo in straight line), but I could tell by the operator accent that he was not from Guyana. The reception would be almost crystal-clear, if my receiving setup were better (I was using a RTL-SDR with a piece of long wire barely touching the outside of the antenna’s jack). While there are repeaters for CB, they’re not as common as VHF or UHF repeaters, where you can even find, for example, EchoLink repeaters, so the international transmission really made into my Brazilian home, and it was even daylight! I only could tell the signal because it was AM modulated.

When we talk about deep space communication, sure some things change, but most of the same rules apply.

These radio telescopes don’t transmit anything at all,

Back in 1974, the former Arecibo radiotelescope was used to transmit the famous Arecibo message (some sources Wikipedia and Universe Today). So, while they’re most used for reception, they can be (and they were) used for transmitting as well. It’s not a straightforward thing, it’s not simply a switch to be toggled receive-or-transmit because they involve different electronic circuitry, but the structure, the dishes and the antenna, can both transmit and receive: for reception, it just interacts with electromagnetic fields, which induces an oscillating electrical current all the way through the structure until it’s filtered (through electronic components such as variable capacitors) and amplified by a receiver circuit, while as for transmission, it conducts an oscillating electrical current and irradiates it, depending on the antenna shape and properties.

Much like a normal telescope doesn’t transmit light.

It’s also a possible thing: https://en.wikipedia.org/wiki/Lunar_Laser_Ranging_experiments#List_of_retroreflectors

I once saw a video of a person touching a grounded sausage to the metallic structure of an AM radio tower, the transmission was audible as the sausage was being zapped. If there’s a merely conductible thing grounded near the tower, I guess it’ll sort of “coil whine” (a well-known phenomenon when electrical components physically vibrate due to the passage of current), converting to sound whatever it’s being transmitted at the moment. This includes the tower structure itself, if the electrical grounding isn’t properly done or if there’s some grounding leak. Otherwise, a grounded thing touching the tower would suffice to convert the transmission into sound, if those radio-telescopes use AM modulation (I’d guess they do, because AM modulation is known for reaching longer distances than FM).

Let S be an endless string which is a concatenation of every binary counting in succession, starting from zero all the way to infinity (without left zero-padding):

S = 01101110010111011110001001101010111100110111101111…
(from concatenating 0, 1, 10, 11, 100, 101, 110, 111, 1000, 1001, and so far)

Let S’ be a set of every sequential group of octets (8 bits) from string S, which can be represented as a base-10 number (between 0 and 255), like so:

S’_2 = [01101110, 01011101, 11100010, 01101010, 11110011, 01111011, …]
S’_10 = [110, 93, 226, 106, 243, 123, …]

I’d create an audio wave file whose samples are each octet from S’_10 as 8-bit audio samples, using a really low sampling rate (such as 8000 Hz or even 4000 Hz).
That sound, that particular sound, is what I’d transmit to the cosmos: the binary counting, something with a detectable pattern (although it’d be not so easily recognizable, but something that one could readily distinguish from randomness noise).

As a Brazilian, not much. Throughout my entire lifetime, I saw some Brazilians there and there wearing Halloween costumes but it’s not as popular here as “quermesses” (kirmess, church fairs, happening mostly on Brazilian’s interiorian towns), Carnival, Christmas or some “important” soccer game (such as Corinthians vs Palmeiras, or Flamengo vs Fluminense).

To me, particularly, no holiday (nor soccer games) holds any importance or meaning. In the end of the day, it’ll be just capitalism mesmerizing people to spend money on temporary things.

It depends.

When the VGA socket I’m plugging the VGA cable has a screwing hole (for example, tower PCs as well as some HDMI-To-VGA adapters) , and I’m intending to let it plugged, I generally do screw them in, not entirely, but sufficiently to don’t let it escape due to VGA cable’s weight (especially if the cable has dozens of meters as well as those cilindrical magnetic thingies that reduces electromagnetic interference).

But one of my laptops have no screwing holes at the sides of the VGA socket so it’s impossible to screw the VGA cable.

In Brazil we officially call it something like “National Enabling Card” (here I’m translating “Carteira Nacional de Habilitação”, CNH, in a literal way). By joining the meanings from words “Carteira” and “Habilitação”, it takes the meaning of “license”. But here’s the catch: while the English part of CNH is “Driver License”, the original Portuguese name doesn’t mention the “motorista” (i.e. the driver). It’d be something like “National License”, focusing more on the collective (nation) instead of who is actually being licensed (the driver, the individual, the citizen).

Edit: I noticed that your map is wrong for Brazil. The Brazilian CNH (the newer models) has “Driver License”, not “Driving License”, among the international languages below the original Portuguese title for the document: English, Spanish and French.

Exactly the same applies to Portuguese: Janeiro, Fevereiro, Março, Abril, Maio, Junho, Julho, Agosto, Setembro, Outubro, Novembro, Dezembro. Only the names for days of week are different here: Domingo (Sunday), segunda-feira, terça-feira, quarta-feira, quinta-feira, sexta-feira and sábado. Colloquially (at least here in Brazil) we omit the “feira” suffix, saying just “quarta” or “segunda”.

Curious to see how the peaks aren’t specifically for a country, but for a region. The tallest peaks within Brazilian territory geographically correspond to São Paulo (actually, Sao Paulo’s neighboring region including Guarulhos as well as Campinas) and Rio de Janeiro. Between them it’s possible to see a smaller peak, it’s probably Belo Horizonte. The peak below is probably Curitiba. There are peaks on the northeast corresponding to Northeastern capitals, such as Salvador, Fortaleza and Natal. The Brazilian north and middle-west are sparsely populated. So, in a sense, the indicators are specifically placed within the map, corresponding not just to countries, but accounting for local demographics as well. Nice.

Formerly through TikTok and YouTube, but now only SoundCloud (especially through Daily drops) and Bandcamp.

Just a tip: always strip the si=... parameter from URLs. The si parameter is a form of tracking from platforms (particularly Youtube and Soundcloud, although other platforms use it as well), so the platforms can know who shared things and who opened the things that the former shared. When you send a clean link, without the si parameter, it’s more difficult (if not impossible) for platforms to determine who shared the link being opened/downloaded.

I’m not sure if it’s a São Paulo (as in the state, not the city) thing, but I had English classes when I was in public high school (“ensino médio”). They weren’t the best English courses out there (i.e. they weren’t comparable to Brazilian schools that specialize in English courses such as CCAA, CNA, Fisk and Wizard), but they offered a good start for those who had no prior knowledge of the English language. It’s also worth mentioning that people who work in IT have more potential to come into contact with communication in English because a lot of documentation is in English. But I totally agree with you that most of the population does not have quality access to English courses.

I’m Brazilian. For personal projects and snippets, especially if I’m going to share their code publicly (e.g. GitHub or GitHub Gists), I often use English. However, when it’s a project from a company I’m working for, I use Portuguese, as every company I’ve worked for so far are Brazilian (and my coworkers were Brazilian as well).

Some surrealist (not exactly “gibberish” in the literal sense) ideas:

• “Let ᚠ be the ζth factor of the ξth Pontryagin dual element from a Laplacian matrix, hence, the numerical representation from a graph, a Pontryagin duality graph. Let Σᛇ be the sum of probabilities such as ᚠ equals to zero. Determine the probabilities for ᛗ considering that sinh(ᛗ-ᚠ) × ᛟφv² + 1/log(dx) = φͲδx³ + ᚠδx² + 2x where δ is the Gompertz constant and x is the nodal variation for each parallelogram axe.”
• “Given that a conventional passenger airliner flies at speeds below Mach 1, what appears to have been the exact sequence of events that led to an Airbus A380 stalling on August 23, 2027, when a flight (whose flight recorder was recovered but was severely damaged internally) carrying 138 passengers crashed into the Indian Ocean during a strong CME that somehow caused the plane to exceed Mach 1 before its crash?”
• “Derek is wandering at the cemetery during midnight. He ate cooked rice and oat flour in the previous day. His cat, Mower, was diagnosed with pancreatitis. The entire Northern Hemisphere is announced to face severe weather due to anomalies within the Gulf Stream. Back at the cemetery, a specific grave seems misplaced: the gravedigger dug through a water pipe, now the grave is overflowing and filled with dirty water. Why those ravens seem to be following Derek?”

I’ve been using it on Android because of its seamlessly crossfade feature (i.e. the next music/replay gets faded in as the current music is approaching the end). I made some loops with Audacity and it’s the only music player that manages to play them endlessly with no gaps.

As a Brazilian, this too. Also, some PTSD from remembering recent Brazilian elections (sometimes USA and Brazil are so similar that they seem like brothers separated at birth, your Trump was our Bolsonaro, your Biden is our Lula, I wouldn’t be surprised if your Harris is our Dilma without the “stockpiling of wind” thing).

I try to find some books regarding occult knowledge. I read them until the dusk (I’ll possibly also try to find candles as well as functional matches).

When dusk arrives, I start to do something else: I’m seeing a feather pen, so it implies that there’s tint somewhere, possibly black tint as the feather’s base is slightly stained in black. I push away those chairs and the table, I roll away that carpet, then I try to draw a big perfect circle on the floor (possibly using that ladder as an improvised drawing compass. Inside the circle, I draw the alchemical symbol for Saturn, perfectly centered over a diametric horizontal line (therefore, an underlined Saturn symbol). I draw six specific letters outside and around the circle, spaced exactly 60 degrees. Then I take that red notebook over the desk, and I start writing:

“Regina noctis, Dea dearum, Thine is my soul.” along with other sensitive content that involves a red liquid.

Then I place the red covered notebook exactly in the middle of the circle. I recite a specific Enochian mantra and I wait until a shivering presence starts.

The secret society of the cryptid goatmen brotherhood (I don’t remember which prompt I used, but I used a fast SDXL model from Huggingface)

Fun fact: the brown-eyed percentage (70-79%) seems to approximately fit the following genetics rule:

+ A  a
A AA Aa
a Aa aa

AA = 25%

aa = 25%

Aa = 50%

50% of Aa + 25% of either aa or AA = 75% probability

Actually, the hotel manager could relocate guests from each Nth room to the (2×N)th (every even-numbered room), as there are infinity rooms. This way, there’ll be as infinity free odd-numbered rooms as there are infinity booked guests. Sisyphus can then choose any odd room for himself and another for his boulder.
