Today is my 🏋️‍♂️ LIFTVERSARY I started lifting exactly 6 years ago today I was super skinny at the time, only 57kg (125lbs) I signed up for a gym at the beginning of December 2019, but I was so scared I kept postponing my first workout I was so intimidated that the first time I went for a workout I only ran on the treadmill I chose the treadmill because it was the only thing in the gym I knew how to use. It was a safe place and I mostly used it so I could look at the rest of the gym from there, and try to figure out how things worked, how people were actually using the equipment It took me a couple days until I went in and actually started lifting weights I have everything logged: the first thing I ever did was bench press with 4kg dumbbells (8 lbs) and I remember my arms were shaking (!!!) I was so weak and thin I couldn't even lift four kilos without my entire body shaking Then I started eating A LOT, way more than my skinny body wanted And I kept lifting heavier every session, so every workout I felt less and less weak until the shaking went away The following year I went on to gain ~15kg (33 lbs) Covid hit shortly after I started lifting, and all gyms closed down, so I had to improvise a gym at home with water jugs just to keep the habit and the early gains Then I started nomading, traveled to Portugal, then Thailand, all while gyms were still closed down, so I had to train at home and in hotel rooms with TRX straps for months I also had to endure through a nasty leg infection in Koh Samui Thailand that got me hospitalized for a week and limping for a while. Still I kept on deadlifting shortly after surgery I had two or three year-long hiatuses here and there, generally correlated with injuries / traveling / moving countries (life is difficult!) but the overall trend is up and to the right!!! I'm now the strongest and heaviest I've ever been, and still a long way to go too! The first pic is me in my second week at the gym. The second pic is from yesterday I've gained ~30kg (66 lbs) total since I started back in 2019, I'm now 84kg (185 lbs)

I started taking 🎾 tennis lessons and I kinda hate it I feel like I learn nothing We’re a group of 4 players. We do the same 3-4 drills over and over, lesson after lesson When I ask why they say it’s because “it’s the bread and butter” That’s the same type of answer I used to get when I was a kid learning English in school and I asked why we kept repeating the exact same grammar exercises year after year I learned no English at all doing those exercises. I only started learning when I forced myself to consume content in English + write down my own thoughts in English In the same way, I feel I learn more tennis just by playing matches, or practicing by myself The drills go way too fast for me to process anything. I haven’t finished hitting my current ball and the next one is already coming at me. I don’t even get to see where my balls land because I immediately need to take care of the next ball, so I get no visual feedback for any of my shots. And as soon as I complete all my shots, I need to quickly run out of the court, because the next person in line is already in position to hit his first ball I spend more brain cycles being aware of the social mechanics of the drills than anything else “Whose turn is it? Is it my turn? What was the next step in the circuit again? Where did the coach say I need to be relative to the cones again? Was that ball for me too?” Now I’m not completely new to tennis. I took tennis lessons as a kid. Didn’t play for most of my adult life and forgot everything. Then I picked it up again 3 years ago, and lately I have been playing a few times per month quite regularly. I’d say I’m completely self-taught. And apparently that means I don’t do things by the book and I make coaches raise their eyebrows. My grip was odd. I was hitting too flat. I was not playing “modern” tennis. The lessons served me in correctly identifying all that and I guess that’s valuable. But I’m now fixing all that in the same way I’ve learned everything in my life: individual, deliberate, unguided practice, all by myself. I book an empty court and it’s just me and my racket; and my phone to record myself. I don’t get much out of the lessons other than the feeling that I’m absolutely retarded. I don’t look forward to the next lesson. I secretly wish it gets cancelled due to bad weather or something. And I’ve only been going for a month and a half. I’ve never felt this way towards tennis, definitely not towards playing matches. I’m always down for a match. I always have fun, especially if my opponent is way better than me and makes me feel like a noob I guess tennis lessons are making me hate tennis? Is this how tennis lessons are supposed to feel like? Do I just need to push through and give it time? Am I too autistic for group lessons? What am I doing wrong?

Eat more eggs (has choline) and you stop being anxious Also great protein for your muscles (6g per egg) My friend @rameerez went from skinny to ripped just eating eggs all day for a year, his fridge looked something like this

Researchers have identified a consistent chemical difference in the brains of people with anxiety disorders: significantly lower levels of choline-containing compounds. A groundbreaking 2025 meta-analysis by UC Davis Health scientists revealed this biological marker through proton magnetic resonance spectroscopy (1H-MRS) data. The study found an average 8% reduction in total choline (tCho) in the prefrontal cortex, a key region for emotional regulation, decision-making, and cognitive control, as well as across broader cortical areas. Analyzing 25 datasets involving 370 individuals with anxiety disorders (including generalized anxiety disorder, panic disorder, and social anxiety disorder) and 342 healthy controls, the researchers documented this reduction as a transdiagnostic feature consistent across different anxiety conditions. This represents the first meta-analysis to identify a reliable chemical pattern in the brains of people with anxiety, pointing to measurable neurochemical alterations rather than purely psychological factors. Choline, an essential nutrient obtained from foods such as eggs, salmon, and soybeans, plays a vital role in brain cell membrane integrity and neurotransmitter synthesis. The authors suggest that heightened arousal and chronic stress in anxiety disorders may increase choline demand, depleting levels faster than dietary intake can replenish them and potentially impairing the brain’s ability to regulate the fight-or-flight response. While the findings open promising avenues for nutritional interventions, experts stress that dietary or supplemental approaches should complement, not replace, established treatments.

@taptanium @levelsio @grok what's the science on eating eggs and serum LDL cholesterol? is it proven that an increased number of eggs in the diet significantly increases LDL cholesterol measured in serum?

@levelsio @rameerez Many of my bodybuilder friends were eating more eggs than they could count. Just watch out for LDL cholesterol rising.

@levelsio @rameerez This is a very bad idea. Over consuming one type of food leads to either extreme sensitivity (causing your body to inflame as soon as you eat the food you over consume) or allergy. Ask me how I know… 😔

Life is extremely simple: - Eat well - Sleep well - Exercise - Do meaningful work - Hang out with friends regularly Fuck up just one of those and you’ll feel miserable. Nail all 5 and the odds you’ll need “therapy” plummet to ~zero
@levelsio@levelsio

I think a big part of this is having a weekly social event of a few hours (like church) is incredibly healthy We now did 53 weekly coworking events in my house and it's a great way for people to stay social Being social in 20s is easy (or was for me), there's always something going on, and you're single so dating is social itself In your 30s it gets harder, people are more busy, you're probably in a relationship, you might hav kids, so you think you need less social cause you get it already from your family but you need friends outside of that Organizing a weekly event whatever it is and kinda putting effort to ask people to come works Some weekly coworking days we have had 30 people, others it's just 3 people, one time nobody came and it was just me! But regardless I (or @rameerez when I am not at home) organize it This one was after my birthday party last week! Anyway I can recommend everyone to organize a weekly event, mine was inspired by @csonotes original Bali coworking events, and you can do same in your town or neighborhood! It doesn't have to be coworking, can also be group workout or board game meetup or debate club, whatever, something to get people off their phones and out the door! And it's healthy!

The 🔴🔵 red/blue button question is just libertarianism vs collectivism The question really is: do you think you can save yourself, or will you wait for someone else to come and save you? It’s ultimately a question about locus of control. The psychological substrate of collectivism is the absence of internal locus. Collectivists believe they’re victims of their circumstances, so there’s nothing they can do to change their situation. Even if the solution is as simple as pressing a damn button. It’s a real-world instance of the hopeless rats experiment. They really don’t think they can be saved, so they surrender to death On a societal level, this is a symptom of how deep the collectivist virus has infiltrated people’s minds So many people bought into the propaganda that Nanny State will come and save them They refuse to believe in themselves. They haven’t exercised individual freedoms for so long their entire free will is atrophied and superseded by the collectivist mindset So many people are suffering unnecessarily because they refuse to do something as simple as pressing a button to save their lives

I am now 100% convinced that Rails app and marketing website should be separate. Rails app lives on subdomain.

@rameerez same problem exists for desktop agents. screenshot based computer use is painfully slow for the same reason. accessibility APIs solve this for native apps the way WebMCP solves it for the browser: structured access to UI elements instead of pixel guessing.

Chrome is working on WebMCP OpenClaw's biggest problem (and any AI agent's) when using a browser is that it's TOO slow and dumb Opens a tab, waits 3s, then navigates to the page, waits 5s, then takes a screenshot, waits 2s, then scrolls, waits... WebMCP solves this The implications are GIGANTIC This means any AI agent could interact with ANY website pretty much like a human would do, WAY faster than any human It's the end of clicking around interfaces and dashboards Websites will just expose tools for AI agents, and AI agents will become first-class citizens of the web
Maximiliano Firtman@firt

Chrome 146 includes an early preview of WebMCP, accessible via a flag, that lets AI agents query and execute services without browsing the web app like a user. Services can be declared through an imperative navigator.modelContext API or declaratively through a form.
