Some people think living with your Mum is something you should be ashamed of. My goal is to have big enough house to have her live comfortably and not feel alone at the same time. Y’all forget who helped you in your first 20 years and beyond and y’all will miss them

That pretty sophisticated attack ngl Just turn on 2FA and turn off the feakin voice mails ppl. Whoever invented this hack tho is a big brain
I got hacked at 3:59 AM without clicking anything. My voicemail handed the attacker my Telegram login code. Here is exactly how it worked, so it doesn't happen to you. 3:54 AM. My phone rings about ten times in a row, No Caller ID. That was not harassment. It was the attack: keep my line busy. Meanwhile, the attacker asks Telegram to log in with my number and picks "send the code by phone call". My line is busy, so Telegram's robot call lands on my voicemail and reads the code out loud to it. Carrier voicemail can often be reached remotely, with a default PIN or a spoofed caller ID. He listens to the message. At 3:59 he is in. Fortunately, the attack was noisy. The calls woke me up. At 4 AM I only wanted to go back to sleep, but I had the presence of mind to check my notifications. Telegram was showing a new login from a device I didn't know. That check is what saved me: I ended his session within minutes. If I had rolled over, the next day would have been a mess. In those few minutes he had already typed /balance, then /start on every old wallet bot he could find in my chats. He was hunting for funds tied to my Telegram. The bots were long dead and nothing was lost. He still had time to set his own 2FA password on my account. What would have stopped it: Telegram two-step verification, with a recovery email. With a password on the account, the code alone is useless. Your voicemail. Change the PIN, block remote access, or turn it off (##002# cancels call forwarding on most carriers). Same for WhatsApp and any service that can send a code by voice call. No seeds, keys or passwords in Saved Messages. Ever. A burst of masked calls at night is a signal, not a nuisance. Check your notifications and your active sessions. I have been building in crypto for more than ten years and I had never thought about my voicemail. Check yours today.

I'm not paid by the hotel lobby or something btw I was a big fan of Airbnb and would prefer to stay in Airbnbs if they were great I want to have a kitchen to cook steak and vegetables, and not go outside to eat in restaurants or get shitty hotel food But I can't book Airbnbs because I the "rating anxiety" is so high because I can't trust the ratings and I end up with my bags in some place that sucks, so the variation of quality is too high to be able to seriously use for travel (except maybe in Asia) So they leave us no choice to just go back to hotels Meanwhile hotels still don't have kitchens! What a missed opportunity! Hotel industry could CLEAN UP entire Airbnb by just adding kitchens to rooms
Imagine choosing an Airbnb over a hotel

Car racing is cognitive enhancement: > 12 hrs on a driving video game, and 60-85 yr olds were cognitively overtaking 20 yr olds > race car drivers do in one brain region what a novice does in 15 > six months later, the seniors kept the gains with zero practice
What Tobi is about to do today is one of the most insane things I’ve seen in athletic performance. He will be racing for 2.5 hours straight. Before immersing myself in this sport for the past few days, I would have thought “oh that’s cool, he’ll be driving a fast car around a track.” That is not what this is. And why I have so much respect for him. Tobi will be driving a car over 180 mph, experiencing up to 4.2 g of force. That will throw his body forward with 715 lbs of force and his head by 67 lbs. Braking action requires up to 200 lbs of leg force. The cockpit will average 104-122°F (40 to 50°C). His multi-layer suit barely allows for evaporation. This will cause his core body temperature to reach 102°F. I achieved this same body temp after 200°F of dry sauna for 34 min. It’s overwhelming. His heart rate will beat between 140-170 bpm. He will sweat up to 170 fl oz (5 kg), losing 11 lbs of body weight. Some classes run driver cooling systems. His LMP2 doesn't. Under these conditions, he will need to maintain perfect concentration for the entire 2.5 hours. He’s fighting for tenths of a second on every turn and every stretch. One small slip up and trouble awaits. Today it’s even more intense… it’s raining. The track is wet, scrambling everything. He has to maintain spatial memory of every other car on the track, the complicated rules to avoid penalty, and constantly strategize overtaking other drivers, communicate with his team on the radio, watch for debris, be aware of slightest nuances of his car, and anticipate other drivers. He did a practice run on Thursday and then a qualifying race yesterday, when he emerged from the car, he was a different human. Unrecognizable from the person who entered the car. Beaming with something like an omnipresence of reality. We celebrate those who are especially good at kicking balls, shooting balls into baskets, and running with balls. What Tobi will do today is alien to those. I struggle to think of a sport equally as demanding. Tobi and I have a lot in common. We’ve both built companies. We both spend a lot of time at the keyboard trying to organize the world in ways that we find beautiful. We both love data, method, and analysis. We both have a love for continuous improvement and will endure any pain required to achieve that next goal. What I’ve not experienced is the unmatched flow state Tobi tells me he drops into when under these racing conditions. I deeply understand what it means to achieve a 102°F core body temperature after 34 min in a 200°F dry sauna. I also know what 3 g’s feels like from being a pilot. These are extremely intense psychological states. I know what it means to apply 200 lbs of pressure with my legs. What I’ve never experienced is all these things, at the same time, for 2.5 hours straight, while maintaining perfect focus. He is new to car racing. Late by racing standards. DHH got him into it a few years ago. During this first year of racing, he endured to overcome the extreme motion sickness that accompanies the physical and mental violence of the sport. The race starts at noon eastern. Tobi will be driving for the first 2.5 hours and then @dhh will drop in, followed by Mathias Beche. The race will conclude at 10 pm. I’ll be in the pit watching as all the data streams in from his car and body and imagining what it’s like to be in that car.

POLICJANT MIAŁ ZGWAŁCIĆ PEDOFILA PAŁKĄ SŁUŻBOWĄ Szokująca sprawa ze Szczecina. Dwóch policjantów usłyszało zarzuty w związku z samosądem, do którego miało dojść na komisariacie. Zatrzymanym był mężczyzna, który później został skazany na 20 lat więzienia za zgwałcenie 9-miesięcznej dziewczynki. Według ustaleń śledczych policjanci mieli go pobić, a następnie jeden z funkcjonariuszy miał zgwałcić go przy użyciu pałki służbowej. Do zdarzenia miało dojść w sierpniu 2024 roku. Funkcjonariusze nie przyznają się do winy. Sprawa wyszła szerzej na jaw dopiero teraz.

Tbh, at this point I won't be sending my kids to school. Will be home tutoring it instead. We can't fix school, but we can fix schooling. Don't see a point to send kid there just to put work into countering it when I can program it from the beginning properly
The constant decel messaging in Europe is insufferable as an adult, but its effect on kids is worse. As a parent, it's your obligation to counterprogram this nonsense. Show them robots, rockets, and wonders of AI. Show them cathedrals and moon landings. Instill hope in progress.

Business idea: a gym where after each use the touched stuff is disinfected before the next use - done by the staff I'd pay for that
The average gym dumbbell carries 362 times more bacteria than a toilet seat. And the wipe-down ritual everyone does after their set kills almost none of it. Lab swabs of gym equipment found over a million colony-forming units per square inch on free weights, with 70% of the bacteria potentially harmful. Staph and MRSA both show up in studies of shared equipment. That part is gross but well known. The part most people miss is printed on the wipe bottle itself. Every EPA-registered disinfectant has a dwell time, the number of minutes a surface must stay visibly wet before the chemistry actually kills anything. Clorox wipes require four minutes. Plenty of commercial gym disinfectants require ten. Nobody at a gym stands there keeping a dumbbell wet for four minutes. Someone grabs it while it's still damp, and below the dwell time you're mostly redistributing sweat and skin oil with a moist towelette. Steam skips the chemistry entirely. Heat past 212 degrees denatures the proteins bacteria are made of, so the kill happens on contact rather than over minutes. It also blasts into the knurling, all those diamond-cut grooves that give you grip and give bacteria thousands of tiny sheltered canyons a flat wipe glides right over. The label wants four minutes of wet contact. The average gym wipe gets five seconds. Mandatory is the right word.

and at the registration it would be clearly stated: if you don't respect the equipment your membership is cancelled
Because high end stuff would get damaged by people who don’t respect the gym

Most will never understand
I was in a hotel room in Brasov, Romania. It was about 7 p.m. I was sitting on the bed and I was due to commentate on an MMA show at 9 p.m. My phone rang. It was my Mum. I picked it up and she said, “Your Dad is dead”. I said, “Okay, I'll call you back”. I hung up. A girl who was in the room with me at the time. She said, “What happened”? I said, “My Dad died”. Tristan was on the other bed. He said, “Dad's dead?” I said, “Dad's dead.” And then we just sat there quietly for about 10 to 15 minutes. And then I said, “Tristan, let's get ready and go do this show.” He said, “Are we still doing it?” I said, “Yeah.” I didn't see the advantage of cancelling our commentating contract, when they flew us there from England. We commentated on the entire show. After the show, we went back to the room. The girl I was with was like, “Oh, is there anything I can do?” I was like, “No.” I was very irritable. She kept asking me if I was okay and it was pissing me off. I was like, “Can you just sleep somewhere else? Just leave me alone. You can't resurrect my father and you just keep asking me questions and you're pissing me off.” She left the room. Dad died of a heart attack in a chess tournament. Literally died on a chessboard. Best way to go for a professional chess player. Tears ran down my face, but I did not cry. There were tears in my eyes, but I don't know if sad is the right word for how I felt. I felt more anxious. Imagine every police officer on the planet just evaporates. You’d be like, “Well, what happens now?" You're nervous, on edge, scared, worried. That's how it felt. I didn't feel sad. I understood mortality well enough. It was more like, “Okay, well, Dad's gone.” So now what? Like, “T, what do we do? Dad's gone. We're the bosses now. We don't get told what to do anymore.” This is weird. That's how it felt. A strange anxiousness. And the weirdest thing about this is that the day before he died, I had messaged him. I was in a nightclub in Brasov. We talked on Facebook every few days. I messaged him randomly: “Dad, my chi feels off. Are you here?” It's the last message I sent him. He never read it. And then he died. The next day I woke up and my inbox on Facebook was flooded with stories from people who knew my Dad. It was very nice for me to read these stories of people I'd never heard of. People were like, “Hi, you don't know who I am, but I was in the military with your father.” “I met your father at a chess tournament.” They told me all these amazing stories of my father doing incredible things. A guy sent me a message saying, “Nobody is going to understand when you tell people how smart your father was. But I just want to tell you a quick story that when I joined the military, I was already fluent in Russian, and I lived with my Russian wife. And within two weeks, your father was correcting my Russian.” It was the Air Force record for the fastest assimilation of a foreign language. It was incredible. Everyone called him E-T, like an alien. They told me all these stories. A kid in Africa contacted me, said, “I can't get hold of your Dad. He's not responding.” I'm like, who are you? “Your Dad was sending me money and paying for my chess lessons.” I didn't know my Dad was sending this kid money. So I sent this kid some money. It was sobering but refreshing for me to read all these nice stories about him. To know that he made an impact on so many people's lives. And the fact that he died while playing chess gave me huge solace. I was happy that he died at a chessboard. That's how he should have died. A hero’s death. A warrior’s death. That's the best death I could have ever hoped for him. On the battlefield. Now I want to affect as many people's lives as possible and die a hero's death. I would hate to die peacefully in my sleep. I can do better than that. If this story ends with me pissing off the government so much that eventually I get drive-by shot somewhere, I wouldn't be disappointed with that ending. I pissed them off and I upset them and I broke The Matrix and I told the truth and they had to assassinate me. I'll take that. My father was 57, which is still quite young. But that's still 20 more years for me. In 20 years from now, I'll be kind of tired. I'm already bored of the women. I'm bored of the cars. I'm bored of the money. I'm bored of the diamond watches. I understand if I continue down the trajectory I'm continuing down, that the end result is going to be me getting into a lot of trouble. And getting killed. I'm ready for the bullet. Dying a hero's death is far better to me than a few extra years of consciousness and dying peacefully in your sleep. A hero's death is the best thing a man could ever hope for. Men used to go out looking for it. My father died a hero's death, He left a massive impact on people's lives. And isn't it a son's job to follow in his father's footsteps? Isn't that the whole point of it? I mean, I do have his name.

Because for them it's their whole identity and now they got leveled to a laptop. Identity crisis much
I can't understand how professional software developers are so attached to days of manually coding. Was objectively a top-tier software engineer (e.g. hired as a quant dev to build high performance systems) and honestly not having to type another line of code feels like such a good riddance. People being so forlorn about agents being good at coding is insane to me. You can continue to ride horses as a hobby, no one can take that away from you, but you should be happy for everyone else to have engines. Coding has and should always (just) be a means to an end. The product was and always *should* be the point. It's undeniable that agents are just objectively better at getting to the point now. Go ahead and manually write code as a hobby.

Real talk
The problem with all of these AI personal assistant things is that people don’t actually want to do stuff. You fucking get that right? Do you understand that? Just like AI tools in the workforce, AI assistants don’t actually abstract decisions for you, they let you accelerate decision making. So instead of making one decision a day and then lamenting you can’t do more, AI assistants are going to let you make ten decisions a day and act on all of them. A miracle? Nah dog, a fucking nightmare. Nobody except type A strivers who need Twitter fodder actually want that. Let me tell you a story. When I got back from college I was inspired. If I could take on an elite university with grit and determination, so could everyone I know. I was all razzed up to get people I know to achieve their potential. What I learned after many years of trying is that absolutely nobody wants to realize their potential. People want to hang out with friends and complain. That’s how the world has worked for ten thousand years. This weather fucks. Can you believe the cows walked off. People don’t want enablement. People don’t want you to take all of their excuses. TV is mindless passive activity. AI assistants are not. They’re telling people that they can achieve more. And people absolutely do not want that. Let me tell you another story. Once upon a time I lead a big process overhaul at work and it was great. Two years later I hired a contractor to do something similar. But I personally didn’t want to have to do a bunch of work. Within a week I knew I fucked in. This contractor kept coming to me with decisions I needed to make. Dude I wanted to not have to think about this. Again, a helper when you don’t actually want help is a disaster. None of these AI assistants will take off because people don’t actually want assistants.
