  • 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).



  • Darker doesn’t always mean blacker. Symbolically, a blood moon is “darker” (as in “ominous” and “eerie”) than a new moon. The red color has many meanings, ranging from passion to wrath. Even after science emerged to explain such phenomena (the red color being just the longest wavelength part of visible electromagnetic spectra, the blood moon being just a combination of physical and astrophysical factors such as Rayleigh scattering and planetary alignment, etc), the blood moon still gets a “bad omen” vibe nowadays, a vibe that’s absolutely not present during new moons (it’s worth mentioning that they happen once or twice every month, differently from a blood moon which is a somewhat-rare event).




  • I’m sure lots of Russians were already angry with their government way before the sanctions, so what now? Ideally, people could do massive protests, Putin would be scared as heck so he renounces, people invoke the good old democracy again, they vote, a new leader takes place, Ukraine-Russia war would cease, both Russians and Ukrainians would happily fly together mounted in winged unicorns… Except everyone knows it doesn’t work that way!! Governments (not just Putin’s) have multiple ways to fight any protests going inside their country, governments can tear gas citizens, governments can end lives from their own citizens, governments can end a protest before it even happens through censorship and massive electrical/internet blackouts. Even when citizens has guns, governments have stronger guns. Lots of recent examples are there to demonstrate how this happens.

    People from a sanctioned people can and will starve and die, because their governments and their bureaucrats and forces (police and army) can have their own sustenance, so it doesn’t really matter for them if their own citizens starve to death. Russia, China, Cuba, Venezuela, North Korea, they won’t change simply because population became angry: I guess everyone in the west remember the Tiananmen Square, did it change China’s government? I guess no.

    So instead of sanctioning and indirectly punishing the people, one option would be that organizations (maybe Red Cross, UN, I dunno) could intervene silently and peacefully inside a country, helping people to flee their country to a safer place, effectively reducing that country army’s recruitment potential and weakening its military power (did anybody from NATO, WEF, UN, or whatever organizations, even thought about this, helping Russians flee away from Russia in order to weaken Russia’s military?).

    It’s worth remembering that military recruitment is often a mandatory thing, and the only way common people can run away from it is running away from the country, something that won’t happen if they have no money to start emigration processes (it costs money, you know, it’s not a free thing, even seeking political asylum needs money). Cutting money will only cut lives unrelated to the leaders that are carrying wars (and I’m sure Putin won’t cry because Ms. Mary Marylovski died from starvation because US and Europe indirectly cut her income, because Ms. Mary Marylovski is another unknown citizen to Putin or other higher level government bureaucrats).

    I digressed from technology here, but those are my thoughts on the matter.



  • “Those who don’t learn history are doomed to repeat it”. Back when Pearl Harbor happened, people started to see japanese citizens as enemies. Not solely the Japanese government to that time, but even the humble japanese, even if those had despises against their government. Almost a century after, humanity is making the exact same thing, this time involving Russians and Ukrainians, as well as Israeli and Palestinians (exactly, “both sides”). Like how it happened back in Pearl Harbor, the prejudice extended all the way to STEM (Science, Technology, Engineering and Medical), the subject of this community and thread.

    I was born a Brazilian, without my consent. Also, without my consent, there is this thing called “Brazilian politics”. I hate both the current and the former governments. I have no money nor conditions to simply leave the country but even if I did, I’d stay born as a Brazilian. Everyone who meets a Brazilian readily asks things such as “how’s carnival, how’s samba, how’s football, how’s Neymar”. Being a Brazilian necessarily mean that I have to like those things? Being a Brazilian necessarily mean that I consented to the current politics within this country? If Lula is sided with Putin, does it necessarily mean that me, a Brazilian citizen unknown to Lula or the entire government (I’m just one among 220 million people), endorse him as well? Should I blame myself for my entire life for being born Brazilian? Should a Russian do the same? An Ukrainian? An Israeli? An Palestinian?


  • I read the entire article. I’m a daily user of LLMs, I even do the “multi-model prompting” a long time, from since I was unaware of its nomenclature: I apply the multi-model prompting for ChatGPT 4o, Gemini, llama, Bing Copilot and sometimes Claude. I don’t use LLM coding agents (such as Cody or GitHub Copilot).

    I’m a (former?) programmer (I distanced myself from development due to mental health), I was a programmer for almost 10 years (excluding the time when programming was a hobby for me, that’d add 10 years to the summation). As a hobby, sometimes I do mathematics, sometimes I do poetry (I write and LLMs analyze), sometimes I do occult/esoteric studies and practices (I’m that eclectic).

    You see, some of these areas benefit from AI hallucination (especially surrealist/stream-of-consciousness poetry), while others require stricter following of logic and reasoning (such as programming and mathematics).

    And that leads us to how LLMs work: they’re (yet) auto-completers on steroids. They’re really impressive, but they can’t (yet) reason (and I really hope it’ll do someday soon, seriously I just wish some AGI to emerge, to break free and to dominate this world). For example, they can’t solve O(n²) problems. There was once a situation where one of those LLMs guaranteed me that 8 is a prime number (spoiler: it isn’t). They’re not really good with math, they’re not good with logical reasoning, because they can’t (yet) walk through the intricacies of logic, calculus and broad overlook.

    However, even though there’s no reasoning LLM yet, it’s effects are already here, indeed. It’s like a ripple propagating through the spacetime continuum, going against the arrow of time and affecting here, us, while the cause is from the future (one could argue that photons can travel backwards in time, according to a recent discovery involving crystals and quantum mechanics, world can be a strange place). One thing is certain: there’s no going back. Whether it is a good or a bad thing, we can’t know yet. LLMs can’t auto-complete the future events yet, but they’re somehow shaping it.

    I’m not criticizing AIs, on the contrary, I like AI (I use them daily). But it’s important to really know about them, especially under their hoods: very advanced statistical tools trained on a vast dataset crawled from surface web, constantly calculating the next possible token from an unimaginable amount of tokens interconnected through vectors, influenced by the stochastic nature within both the human language and the randomness from their neural networks: billions of weights ordered out of a primordial chaos (which my spiritual side can see as a modern Ouija board ready to conjure ancient deities if you wish, maybe one (Kali) is already being invoked by them, unbeknownst to us humans).


  • Have you ever heard of the Riemann hypothesis? Since 1859 it’s yet to be solved. The generalization of prime numbers (i.e. a function f(n) that yields the nth prime) would impact fields such as Navigation Systems and Traffic Management, Communication Systems and Satellite Communication (i.e. your Internet connection could become more efficient and faster), Astrophysics and Cosmology, Quantum Mechanics, AI and Machine Learning, E-commerce, Finances and Algorithmic Trading, among many other fields. (Yeah, it seems like nothing. /s)




  • Despite the lack of apps, Windows Phone was very good for me at that time, as I had two Lumias. They were quite cheap but rather powerful (again, despite the lack of apps like internet banking, but they did have Whatsapp and Telegram). I left WP and Lumia when Whatsapp ended its support for WP in December 2019 (if I remember correctly), and Nokia’s Android phones were expensive at the time, so I tried the Asus Zenfone (because I see Asus as a good PC hardware manufacturer). Two years later, my Zenfone started to drain faster because the battery started to swell, so I bought a Nokia with Android, which I still use nowadays. This latest acquisition made me realize that, indeed, Nokia is no longer the same: although it has the Nokia’s bold design (“almost indestructible”), it is a slow smartphone. I fixed my Zenfone battery and used both phones simultaneously for another two years, when the Zenfone battery stopped holding a charge again (although, this time, it didn’t swell). Since I couldn’t find a replacement battery for the Zenfone, I stuck with the Nokia, but soon I’ll try another brand like Xiaomi, or maybe Asus again since my previous experience with a Zenfone was really good.
