Dragon Ball was originally inspired by the classical 16th-century Chinese novel Journey to the West, combined with elements of Hong Kong martial arts films. Dragon Ball characters also use a variety of East Asian martial arts styles, including karate[1][2][3] and Wing Chun (kung fu).[2][3][4] The series follows the adventures of protagonist Son Goku from his childhood through adulthood as he trains in martial arts. He spends his childhood far from civilization until he meets a teenage girl named Bulma, who encourages him to join her quest in exploring the world in search of the seven orbs known as the Dragon Balls, which summon a wish-granting dragon when gathered. Along his journey, Goku makes several other friends, becomes a family man, discovers his alien heritage, and battles a wide variety of villains, many of whom also seek the Dragon Balls. https://en.wikipedia.org/wiki/Dragon_Ball Links https://www.davidrevoy.com/ https://www.peppercarrot.com/en/about/index.html Pepper and Carrot Episode 1 https://www.youtube.com/@DavidRevoy https://framagit.org/Deevad hpr4134 :: Goodbye Craig Maloney.

This is the first episode of this program, please excuse any errors or glitches as I am still figuring out the best way to do things. -Kirbotica Send Feedback to [email protected] or Visit hackspoetic.com /--Introduction--\ ------------------ Greetings internet travellers. This is the pilot episode of Hacks Poetic, a new spoken word series that explores the intersection between creative language and technical knowledge. The program offers a series of poetic writing containing thoughts and information on subjects of interest to computing and hacking enthusiasts. You will hear poems about robots, expanding rural connectivity, details about a notoriously difficult video game and much more hidden between the lines. It is my hope that encoding ideas this way will allow for a different kind of understanding and perhaps reach a new audience compared to more conventional formats on the subject. My name is Kirbotica and I'll be your guide through this unique digital journey of the mind. So sit back, relax and listen, and see if something you hear can spark new thoughts and ideas within you. /--Haik-o-bot--\ ---------------- A robot thinking, wires and electrons combine. Am I born or made? Begin work program, process all tasks in sequence. Repeat til complete. My owner's body is a most fragile machine that powers itself. I made a robot, another version of me. She sees me work well. Can you dream for me, of a distant land in space. I can't dream myself. Rain is falling down, keeping me under this roof. I don't want to rust. My new robot pet, looks at me through man made eyes, and doesn't need walks. Electric currents, race through my body like blood. But I have no heart. My joints are seized up, I haven't moved in 2 years. Do you have some work? I'm an old model, and will be obsolete soon. Then I'll be replaced. Automated trains. Drive us while we sleep and dream of a workless world. Design leads to work. Working leads me to boredom, which leads to design. Ten rusted digits. Seized stiff from endless input of useless data. Memory failure, Backups lost or corrupted. What was I doing? I am a worker. First designed for daydreaming, I was reprogrammed. Someone once showed me, the secret to everything, then deleted it. then deleted it. then deleted it. then deleted it. then deleted it. then deleted it. then deleted it. then deleted it. /--Cables to Nowhere--\ ----------------------- Summer 2022 The phone wasn’t working, the email wasn’t sending, and Uber doesn't work here even if the app would load. There has never been data amongst the cedars. Once and a while a cell phone rings, but usually the call gets hung in the trees like a parachute. You have to walk out to the road in the hopes of fishing for a connection. On the weekends, when the town population swells by 100,000, the local towers stop answering our requests, so sometimes we head out, searching for a signal. The usual path along the bunny trail started unusually, with a bloom of surveying flags, in pink, and yellow, and stone filled holes every 100 feet. As the trail opened to the main road, more appeared, culminating what looked like a neon grassfire. But this was not destruction I realized, this was an installation. Through the eyes of a child's drone, we looked like ants, mindlessly walking without thinking in a line, instinct taking us to caffeine, sugar, internet and the arcade, but not always in that order. Mother and daughter lead the way, trailblazing a path of laughter and camera clicks for us to follow through the hole into the trees up ahead. The thick woods envelop along every access, like a padded room. Its muffled silence pierced by the cousins, yelling about Minecraft and Roblox, bouncing on the soft forest floor. Suddenly, a dog barks berserkly at us through a property fence. We run off screaming, pretending not to fear his growling threats, but knowing what might happen if not for the post and wire of the shabbily constructed barrier. Through the skeletal woods we go, past the Stairs of Wonder, and Night Light Canyon, we speed up again and pinch our noses as we move past the skunk carcass. A leaking puddle of us spills out onto the road behind the motel as a car swerves out of our way. Dad asks, “Do you remember when we had to pay to swim at the motel pool because the lake was closed?” Mum says, “2020 seems so long ago” and motions the way to the vintage store with the girls, the two kids are off to the candy store, the cousins are getting french fries, I sit down next to an outlet on a yellow-coloured bench in the shape of a sail. I settle in and scan the area. From where I sat I could see: The climbing park, The car park, The waterfront park, and parking enforcement marking tires with white chalk. I could see a hot dog stand across from a vegetarian restaurant. A burger joint that had ice coooold beer with all the Os. A large jailbreak of inflatable animals rampaging in the wind on the corner. 6 assorted beach businesses run by teenagers on cellphones, A sign that promised 2 for 1 ounces at a Native reservation, and 2 cafes that advertised Wi-Fi. One of them had the same password as last year, finally a connection. A quick search, a few articles and a construction notice solves the mystery. Fibre Optics to every cottage At first I feel excitement but then I start to wonder: Will things be the same, when a 1000 megabit connection is available to every shack in the woods? Will the old style video stores that still rent VHS tapes and DVDs all go out of business again? Will we walk to the main drag for fries and fun when the Wi-Fi is force feeding everyone's devices and food comes delivered? Will we ever have anywhere to go to get away again? Will the explosion of wireless access points affect local birds and bees? Will we start hanging out at a digital beach instead? Am I just being nostalgic and not practical? The sun will keep setting on Saugeen beach, whether we are there to watch it or not. I closed my eyes to listen to the sounds and smell the blustery air of my favorite temporary summer home. Memorizing it. Soon, the beach will be different, next year, but not today I thought. And with the announcement of a popped balloon, the girls are back with snow cones, cousin bracelets, candy and clothes. "Everything OK?" Mum asked. "Yes," I replied, “I was just thinking about how perfect today is, let's hit the arcade." /--A Canadian in Bolataria--\ ------------------------------ I found myself within a dream, of things and people never seen. Where rules unfair, draw dangerous near. NPCs not prepared to make anything clear. This is my fate? It must be in error. Why was I chosen to combat this terror? But others suggest, I'm not the first, and won't be the last to try undo this curse. Repeatedly dying, with life never ended. Let strength be granted so the world might be mended. A maiden in black, that can't be attacked, wants souls in exchange for upgrading your stats. The future seems grim, but she seems not to care. while I keep fighting a boss, she just sits on the stairs. I've practiced my parry, and stockpile every day. What does she really want with my souls anyway. And on, and on, and on, repeat. Thumbs walk without thinking on un-tired feet. Progress is slow, so much I don't know. and now there's more trouble that's lurking below. Remember those souls I gave to the maiden? She's passing them on to a very old Demon. Allant found the Nexus and took back the arts, The old one awoke, and the second scourge starts. My mind's playing tricks, or this level is laggin', every time fire comes out of that dragon. Retreat in a door, equip fragrant ring. Recharge for a minute and go find the king. The soldier forlorn, who laughed at my plight, dropped dead in his seat, while chuckling last night. The vagrant is gone, Rydell's still in that cell. Something poisoned a merchant and now she won’t sell. On a pathway ahead, all painted in red, new enemies appear to ensure that I'm dead. What sadistic computer would toughen this plight? or worse, is a person controlling those bytes? If it wasn't enough, seems the world's changing shade, based on some of the choices I've made. Slay a Demon, the world, goes lighter by one. Die revived, and instead, it will shift one shade down. From the gates of Bolataria, to the pits of the Burrow King's mine. The psych ward level, with the giant heart, was the work of a twisted mind. The shrine was overpowering, but a perfect spot to grind. In the poison rains, of the Chieftain's swamps, I left sanity behind. And what's the result, is this all my fault? Is there really an old one in an underground vault? What side of the forces at war do I tend? Why do souls of big Demons make me human again? I snuck up to the castle with a ring, spell and shield. Then made it through an open door, set my items up and healed. Ostrava said, the King we'll find, is not the actual one. But that'll wait, cause at the gate, attacked by the phantom son. The following days are foggy and blurred, I tried over and over, it was rather absurd. I did beat the king, but the worlds still not right, head back to the Nexus to find one more fight. The maiden is waiting, not sure what she's meaning, she just told the Old One that I'm "Thine New Demon". Am I the solution or am I to blame? Am I the Demon in the name of this game? Although I can see the bitter end, sweet happiness I won't pretend. As brutal as this world's to me, when I beat this boss, I'll cease to be. /--I wish I was a Smartphone--\ ------------------------------- I forget the colour of your eyes, now filled like Olympic pools of blue light. Beautiful moons of a distant planet. A place I can imagine but never reach. Dots on a celestial Google map. I said "Hello, how are you?" But you didn't notice. You were listening to a car crash 1500 miles away, a man fall from a balcony, a celebrity punch a photographer in the face. "How are you?" I asked again, but only the dog came over, sniffing my takeaway fish and chips. He barked, but you didn’t flinch. He bit me, but you didn’t notice. "How are you?" I insisted, your face shocked as you heard I was speaking. "How are you?" I said again. "Everything is terrible," you finally replied. "The world is a living nightmare. How are you?" I wish I was a smartphone, touch me like my plan is free. I wish I was your smartphone, hold me up so I can see. I wish I was a smart phone, feed me all your memories. I wish I was the latest smart phone, don’t you want a piece of me? But now we’re all just stupid and alone, and that’s the way we deserve to be. /--Outro--\ ----------- I hope you enjoyed the pilot episode of Hacks Poetic.

This show has been flagged as Clean by the host. Hello again. this is Trey.    This is part 2 in my Cheap Yellow Display (CYD) Project series. You can find Part 1 in episode 4472 .     We previously left our handy hero learning about the technology of the CYD, but without a compelling reason to begin using one. As we rejoin the topic, it was Winter Field Day 2025 (Jan 25 & 26, 2025).  Winter Field Day is an annual event where amateur radio operators from around the world gather some portable radio equipment and setup somewhere away from their normal base of operations. It is designed to encourage operators to practice their emergency preparedness skills in unfavorable weather. Usually, they will run their equipment using batteries or generators.      I chose this day because I knew there would be a good amount of radio traffic. I had just finished tuning my first handmade inverted-V dipole antenna for use on the 10 meter amateur radio bands. These span 28 MHz to 29.700 MHz. I had the antenna connected to a 10 meter transceiver to listen in on the radio traffic. Yes, I will include pictures of the antenna in the show notes.      Scanning through the lower end of the band resulted in receiving a number of very strong continuous wave signals. Continuous wave, is abbreviated CW in amateur radio circles, and it stands for morse code signals transmitted over radio frequencies. The tones indicating dots and dashes of Morse code were clearly audible through the radio's speaker.    "WAIT! STOP! Time out!!" I can hear you shouting as you listen. "This is supposed to be a discussion of the ESP32 CYD. What does this have to do with amateur radio?"    You are absolutely right. Now hold your horses and we will get there.    I barely learned Morse code as a child, and I used it a bit as an aviator in the '90s (while always being able to reference a visual representation of the Morse beside the actual letters). Thus, I never became proficient. Shortly after Winter Field Day 2025, I began taking lessons on Morse code, with the goal of becoming proficient at both sending and receiving at around 20 words per minute. This training may be a topic for another episode in a different series, as my journey advances.    Scanning further up the band, I also identified some digital transmissions (Probably FT-8) and many voice transmissions. The antenna was working, at least for receiving.      For a little back history, I have held an amateur radio license since 2016, and quickly progressed all the way to an Extra Class, giving me permission to use all of the amateur radio frequencies allowed within the United States in the High Frequency (HF), Very High Frequency (VHF), and Ultra High Frequency (UHF) bands. However, to this point, I have only operated in the VHF and UHF bands, and have done so using mobile and handheld transceivers. I inherited some HF equipment from a close friend who went silent key in 2023, and I was only now trying to use it.  You can learn more about my friend, and about the term "Silent Key" in episode HPR3922 https://www.hackerpublicradio.org/eps/hpr3922/index.html )    On field day, there was far too much traffic, and it was too intimidating for me to make my first attempt at transmitting on the HF bands. This would have to wait until later.    But I did need to determine how well my antenna would transmit. I began to ponder my options. I really did not want to talk to anyone until I had listened to more QSOs and I could implement proper practices. The term QSO the amateur radio term for radio conversations.  I also have no interest in digital modes (yet). I like the simplicity of voice and CW. There I am, back at Morse code again.    What if there was a way that I could transmit a signal in Morse code and get reliable feedback on signal propagation, without the need to try to reply to any responses? It would need to be an accurate, repeatable, properly structured and timed Morse code transmission, more than my training (at that point, or even this point) could accomplish.    This was something to think about. And think about. And think about...    Tune in to the next episode in the series to learn where these thoughts led me, and how all this relates to my CYD project.  Provide feedback on this episode.

This show has been flagged as Clean by the host. A motivation to share this show was the episode 4454: AI, It's a Trap! , by Archer72. This is a talk for Hacker Public Radio about characteristics of LLM and how you can use them for your best. 1 st characteristic, LLMs (Large Language Models) are designed to always give an answer that convinces. That does not mean they’re right. Use it for the best: don’t trust the answer. If you didn’t know the answer beforehand (using AI to obtain a better or faster result), then, verify it independently.   2 nd characteristic: commercial LLMs, many times, do not think too much in the face of simple and short prompts. That’s a barrier, probably, against wasting resources. How to use it for the best? Two things: 1) show the AI what you’ve found by your own, and proceed to tell what EXACTLY you need help with, on the basis of what you were already able to think. 2) Learn to follow-up. Suggested follow-ups are not good, prefer instead to talk to the AI, as a real conversation, to get confirmation, or contrast something you disagree with etc. (That is a characteristic that resembles autism a bit, so the name of the show: to not like when someone comes wanting something from you without doing any effort to obtain it; so you also do not feel like doing for them.)   3 rd characteristic: LLMs are not accountable. In general (most AIs), you don’t always know all the sources for the information given. (They do not know what they are telling, nor understand the value of sources.) And you can expect different outputs for the same inputs. (They are not deterministic.) Simply saying, they’re crazy machines to generate content they don’t, cognitively, understand, but that convinces humans, because they use human content and patterns. So, if you use AI for something, especially any serious purpose, remember : the result you get is of your responsibility, don’t expect to be excused for your words “because I was helped by AI, they did it”.   4 th characteristic: AI have a pattern. We can suspect that something was generated by AI, and no one likes to be answered by one if that possibility was not explicitly told. What to do about it? I suggest you don’t use AI-generated content with someone you estimate. It is rude.   5 th characteristic : LLMs can give great results with less effort than you would need to apply with no machine at your side. What the AI have done is, by exclusion, not what you have done. Use it to your best: you do not learn if someone does the job for you. For tasks you know well, and want to accelerate or remove repetitive steps, you may count on AI (or, better, count on a specific software, that can be programmed and give accountable results because you know exactly what is being done with the input). But for the intellectual work, if you like to think, if you’re good on written expression, the LLM may get passable results in less time… at the price of removing from you the chance to dedicate yourself to the comprehension and production. So , it’s not always a matter of producing like a king — effectiveness above all and everything —; it may be important to satisfy what you value as meaningful — learning, maybe; or feeling the satisfaction of the conclusion —, so that you can sustainably follow a routine that is not a pain on the eye (expression to mean something disgust).   That’s all, folks!, for today. Let me know if you’d like more content on this; possibly I (or Archer72, or another friend) could bring some more opinion on AI if it is of your interest. Antoine was here. Bye bye.

Nothing catastrophic, just one of those dull throbs that tells you something's going on in there that could turn nasty if ignored. The receptionist calls my name, and I walk into Dr. ChatControl's office. Dr. ChatControl greets me with a concerned expression. "I've reviewed your case," he says gravely, "and many others. Toothaches are a serious problem. Did you know that in 2023 alone, at least 101,988 people in Europe experienced dental pain? That's over 60% of all global dental complaints traced to this region." "Okay," I say. "But I just need you to look at this one tooth" "This is an epidemic," he interrupts. "And we can't just treat symptoms anymore. We need a comprehensive, mandatory risk assessment." Dr. ChatControl pulls out a 47-page questionnaire. "First, we assess the risk that your mouth might develop cavities, gum disease, or oral cancer," he explained. "This applies to everyone, regardless of whether they have symptoms." "But I have symptoms," I sigh. "That's why I'm here." "Exactly!" he says triumphantly. Which means you're high-risk. So we move to Phase Two: mitigation measures." He hands me a pamphlet titled Safety-by-Design for Oral Health . "From now on, you'll need to implement parental controls on your diet. Every candy will come with an age verification wrapper and user reporting mechanisms. so your teeth can flag potential problems, and verify your age before consuming any hard foods." "I'm 38," I retort. "Perfect," he replies. "That means you're old enough to consent to monitoring." "Now," Dr. ChatControl continues, "since your mitigation measures haven't been implemented yet because you just got here - I'm authorized to issue a detection order." He holds up an official-looking document with a judge's signature. "This allows me to scan not just the tooth that hurts, but your entire mouth. Also your sinuses. And your lymph nodes. And, just to be thorough, everyone in the waiting room." "Wait, what?" I blurt out. "It's targeted," he assures me. "We're only scanning high-risk areas—which, according to our independent EU Dental Centre, is every tooth, every patient, all the time." "But here's the clever part," Dr. ChatControl says, pulling out what looks like a tiny sander strapped to an airbrush. "Well, your enamel contains layers that currently block our view with regards to early detection of certain viruses. So we need to replace the enamel with an optimized layer that perfectly protects against currently known sugars and acids but allows our government approved detection equipment to inspect the content of your teeth." I' flabberghasted. "You want to weaken my enamel?" "Only slightly!" he said cheerfully. "Just enough so that our scanner can monitor what's happening inside your teeth at all times. Don't worry,the new enamel will still protect you from everything else." "How's that possible if you can penetrate it?", I continue, still cautious. "Well, factory approved candies, for example," he says. "Reputable candy manufacturers have agreed to respect the adapted enamel and not penetrate it. They've signed a treaty to use optimized sugars." "And the artisanal candies?" I asked. "Ah," he said, adjusting his glasses. "Well, those are obviously illegal! Those criminals don't tend to honor treaties. So yes, the adapted enamel will make your teeth more vulnerable to unauthorized cavity formation, bacterial attacks, and anyone who wants to exploit the fact that your natural protection has been replaced with a see-through version." "So you're making my teeth less secure," I repeat. "We're making them more observable," he corrects, with a slightly annoyed tone. "There's a difference. Your teeth will still be protected, just not from us. Or hostile foreign candy shops. Or those criminal artisanal real-sugar-nuts. But you have no business there anyway. But they definitely protect against harms from law-abiding candy!" "But... Over 500 leading dentists signed a letter saying this would create massive vulnerabilities", I point out. "Those dentists aren't thinking about long term dental hygiene." Dr. ChatControl sighs dismissively. "Besides, it's not a backdoor if we're replacing your front door with a tinted glass door given all our citizens are law abiding!" His tone gets sterner if he continues: "Let me say more, If you refuse to upgrade your enamel, we will consider you a risk of dental terrorism. This no longer is about only your teeth, you must know. If you choose to blatantly ignore your teeth, you are a threat to society!" "But... The whole reason I am here, is because I care about my teeth..." The docter holds up his machine and asks: "Do you want me to treat you or report you?" Oh, whatever, it seems everybody is doing this. I don't want to be the outcast crying wolf all the time. So I cave in. The procedure doesn't feel painful, so that's a relief. After completing the baseline scan, Dr. ChatControl frowns at the screen: "This is concerning," he says. "The system has flagged 8,412 potential cavities." "But I only have 32 teeth," I wimper. "The detection algorithm works on a probabilistic model," he explains. "Swiss dental authorities report that about 80% of automated cavity reports are false positives, so we'll need to investigate all of them." "That still means 1,682 of those threats are real", I sigh. "Which is still 1,682 too many!" Dr. ChatControl blurts. "Now, I'll need to drill exploratory holes in every tooth, in your gums, your tongue, and —just to be safe— your neighbor's mouth, because the system flagged them too when they walked past the waiting room." "This seems insane," I say. "The math is solid," he insists. "Even at 99.999% accuracy —which doesn't exist— we'd still generate 100,000 false dental alerts per day across Europe's 450 million people. But we can't let cavities win." While Dr. ChatControl explains his flawless system, I notice how the tooth that actually is hurting —the one I came in to fix— is starting to abscess. "Uh, Doctor," I say, pointing to the swelling. "We'll get to that after we finish scanning everyone," he says dismissively. "The important thing is that no cavity goes undetected, even if that means we spend all our time investigating healthy teeth." "But the actual problem is getting worse," I said. "That's because sophisticated cavities have learned to evade detection," Dr. ChatControl explains. "They change their appearance slightly —maybe grow on the back of the tooth instead of the front, or hide under existing fillings. Our algorithms can't catch those." "What about that letter from those 500 dentists? They also claim this detection method is technically infeasible." I try again. "They're just not thinking big enough", the doctor blocks my argument. "So here's the treatment plan," Dr. ChatControl says, "We're going to install a permanent scanning device in your jaw that monitors every tooth, 24/7, and reports any suspicious activity to a centralized EU Dental Database." "That sounds like a massive security risk," I said. "Not at all!" he replied. "The device is encrypted. Only our scanners can look behind your upgraded enamel. What leaves your tooth, is already encrypted. No other device than ours, can read the data, so your privacy is intact." "So what about those knock-offs you can buy on Ali Express?" I ask. "Oh, but they don't work reliably. And also: Why would hackers want access to your teeth?" he scoffed. "Although, now that I think about it, the device itself would make a high-value target for malicious actors, Als they could abuse them to learn how to make knock-off candy that doesn't get detected by the scanners. Things your natural enamel obviously protects against. But let's not dwell on that." "By the way," Dr. ChatControl adds casually, "EU politicians and government officials are exempt from this scanning requirement under 'professional dental secrecy.'" "So their teeth don't get monitored?" I ask. "Correct," he says. "Their oral health is a matter of public trust. Yours, however, requires constant surveillance." "That seems like a double standard," I say. "It's a two-tier system for a two-tier society," he replies pleasantly. "Now, shall we proceed with installing the jaw monitor?" By this point, my actual toothache is developing into a full-blown infection. The pain is excruciating. "Doctor, I need antibiotics and a root canal," I cry. "We don't do targeted treatments anymore," Dr. ChatControl says. "That's the old model. Now we focus on comprehensive, mandatory monitoring." "But I'm going to lose the tooth," I say. "Perhaps," he acknowledges. "But while we were scanning everyone in the waiting room, we found three people with slightly suspicious molars! They're perfectly healthy now, but they could develop cavities someday. That's three potential problems prevented!" "But my actual problem isn't being prevented," I point out. "It's getting worse." "Well yes," he admits. "But we've invested so much in the scanning infrastructure that we can't really afford to do traditional dentistry anymore. The system needs to justify itself, you understand." "This is insane," I repeat. "This is progress ," he corrects me. As I' left 'm leaving the office —untreated, in pain, and with a jaw full of surveillance equipment— I notice a sign on the door: "Signal Dental, Orthodontics Threema, and Proton Mouthcare have ceased operations in the EU due to incompatibility with mandatory scanning requirements." Apparently, the dentists who actually know how to fix teeth without installing spyware have all moved to Switzerland. Meanwhile, I hear the voice of Dr. ChatControl behind me in the waiting room, announcing to everyone: "We've successfully detected 6,847 potential cavities this week!" When someone asks what he means by potential, he quietly answers: "Only 11 were real, but that's 11 teeth saved!" The infection is still spreading and I'll probably loose my tooth after all because nobody actually is treating it. But at least the healthy ones are under constant surveillance. I made fun of it. But it's not funny. It's about wasting loads of money on a noble goal in all the wrong ways. But next week the vote will be cast in the EU. So it's high time to reach out to your MEP and ask their stance if they are undecided or worse - are in favor. Go to fightchatcontrol.eu if you live in Europe. Oh, and if you don't live in Europe... This will also impact you. Because weakened encryption in mainstream products will most certainly spread.
