Fourier wrapped a signal around a circle in 1822. Every Spotify equalizer, every noise filter in your AirPods, and every frequency layer inside ChatGPT runs on what he found. The trick is simple. Spin the signal at different speeds. When the spin matches a hidden frequency, the center of... show more

Alan Oppenheim, MIT professor: "Jump Trading pays quants $650K to pull one real signal out of market noise. I wrote the textbook on that exact math and taught it for free." this free MIT lecture is the math the whole "quant edge" is built on, and almost nobody selling you a course will name it. the man teaching it wrote the signal-processing textbook every engineer on earth learned from, and he put the lectures online for nothing. here is the idea. a price chart is a signal buried in noise. most of what you see is random static, and hidden inside is a faint, repeating pattern with real mathematics for pulling it out. that is not a metaphor. jim simons was a codebreaker who did exactly this to enemy transmissions, then pointed the same math at the market and made a hundred billion dollars. none of it is new. oppenheim taught this in 1987, the math is older, and every lecture is free. same story i told in the article above. the edge was never a secret formula. it was knowing a market is a noisy signal, and having the tools to read it. here is what the gurus skip. the math to separate signal from noise is free and everyone has it. the edge is cleaner data than the next desk, and the discipline to trust a faint signal across thousands of trades instead of chasing the static. the filter is free. the patience to use it is not.

Alan Oppenheim, MIT professor: "Every trader alive uses a moving average. Almost none of them know it's a filter, and funds pay quants $600K for the version they were never taught." a moving average is a filter. it smooths a jumpy price to reveal the slower signal hiding underneath. that is all it is, and it is the bluntest one there is. the same math gives you filters that lag less and cut more noise, and that gap is a real edge. this is the second half of what Simons was doing. first you accept the market is a signal buried in noise. then you build the filter that reads it, and the moving average on your chart is the crudest possible version. Oppenheim builds the real ones at the board in this lecture. here is the catch. a filter only helps if there is a real signal under the noise. smooth pure randomness and you will see a beautiful trend that means nothing. the filter is free. knowing there is a real signal worth filtering is the edge.

As someone who ships LLM systems in production, this Laplace transform video is the closest thing to a "why Mamba beats transformers" explainer I've ever seen released for free. Everyone thinks attention is what makes LLMs powerful. Laplace proved in 1785 that any signal breaks into exponential pieces - locate the poles, expose the frequencies. Mamba and Claude run on this exact trick. 34 minutes. Bookmark & watch today. The math is older than the United States.

Kevin O'Leary: The 80/20 signal-to-noise rule Steve Jobs & Elon Musk used to outperform everyone "I used to work for Steve Jobs in the early 90s making all of his educational software. I would say, 'Steve, we've got to do some market research on Oregon Trail. It's in 110,000 school buildings. It's going to cost you 12-15 million bucks. We want to find out what the students want, what the teachers want, what the parents want.'" O'Leary shares Steve's response: "Steve would say, by the way, not a nice guy, not a nice guy, he would say to a room full of people: 'Kevin, I don't give a shit what the students want or the parents think or anybody thinks. It's what I want. They don't know what they want till I tell them what they want.'" O'Leary pushed back: "I said, 'Steve, you sound like such an asshole. You have no idea what that sounds like.' He said, 'No, no, that's how it is, Kevin. Are you making money with me? Am I your fastest growing OEM? Have we not been wildly successful and continue to be?' I said, 'Yes, Steve, that's true.' He said, 'Then shut up and do what I say.' That's how he would talk to you. 100%." O'Leary explains what he learned: "There's a concept that he understood that very few people focused on back then, signal-to-noise ratio. His vision of signal was the top 3 to 5 things you have to get done in the next 18 hours. Not your vision for the business next week or next month or next year. Just the next 18 hours you're awake. You're going to get those 3 to 5 things done that you have deemed critical for your mission. They must get done today. Anything that stops you from doing that is the noise." He shares the ratio that made Jobs successful: "For Steve Jobs, the signal to noise ratio to be successful was 80/20. 80% signal, 20% noise. And I knew that to be true with him because he would email me at 2:30 in the morning and expect me to get back to him." O'Leary compares Jobs to one other person: "The only other person I've seen with a higher ratio than that is Elon Musk. He has no noise. He does not deal with noise. He is 100% signal. 24 seconds of every 30 seconds. 60 seconds of every minute. 60 minutes of every hour. The 18 hours he's awake, it's all signal. And look what he's achieved." He acknowledges the tradeoff: "That's very awkward for him socially, because noise is dealing with your family sometimes. Noise is saying hi to a friend. Noise is doom scrolling on social media. Maybe playing your guitar. But very few people on Earth, and if you go back in history, you'll find that the geniuses of their time were close to 100% signal." O'Leary shares another example: "Bezos will not make a decision after 1:00 in the afternoon, because he felt that the noise was too high. The signal for him was in the morning hours." He summarizes the lesson: "This is a crucial aspect of success that I now understand. It defines an entrepreneur. A man or woman that understands the signal-to-noise ratio, that focuses on that, they'll be successful. The ones that can't, that get down to a 50/50 signal to noise, they'll fail. It's that simple."

THIS GUY SPENT 5 MINUTES SETTING UP A $20 CLAUDE WORKSPACE AND TURNED 30 MINUTES OF DAILY PROMPT CHAOS INTO A SYSTEM Most people open Claude, type 1 messy prompt, rewrite it 10 times, get the same generic answer and call the model “bad.” He opens Claude Cowork, adds the project rules, past context, working files, examples, decisions and a clean place for the model to remember what it is doing. Same Claude. Same $20 tool. Completely different output. The funny part is there is no magic prompt here. No secret template. No “10x Claude” trick. Just the boring layer Karpathy keeps pointing at: context, memory and structure before output. A setup like this can save 30 minutes a day, which is 15 hours a month. If you use Claude for client work at $50 to $100/hour, that is $750 to $1,500/month in time you stop burning on repeated prompts. The model is real. The output is real. The edge is in not making Claude start from zero every single time.

One of the most valuable lessons I ever learned came from Steve Jobs. He told me that in an 18 hour workday, you only need to accomplish three important things. Those three things are the signal. Everything else is the noise. The challenge is learning the difference. That idea completely changed how I think about productivity. Today, one of my phones is dedicated to signal, which is business, decisions, and the things that actually move the needle. The other is full of noise, social media, videos, endless scrolling, and distractions. There’s nothing wrong with either, but if you can’t separate signal from noise, the noise will consume your entire day. Get your three things done first. Everything else comes after.

Steve Jobs once told a room full of people: "I don't give a F**k what the students want, the parents think, or anybody thinks. It's what I want. They don't know what they want till I tell them what they want." Kevin looked Jobs in to the eye and said: "Steve, you sound like such an a**hole." Jobs did not flinch. "Are you making money with me? Have we not been wildly successful? Then shut up and do what I say." That was Steve Jobs. Not a nice guy. Not even a little. But here is what that man learned from working with him. And it is the only success formula that actually holds up. Kevin worked for Steve Jobs in the early 1990s, building educational software. One day he walked into a meeting and told Jobs they needed to do market research on Oregon Trail. A massive title. Running in 110,000 school buildings across the country. An update would cost 12 to 15 million dollars. He wanted to know what students wanted. What teachers wanted. What parents wanted. Jobs stopped him cold. He did not want surveys. Did not want focus groups. Did not want to know what anybody thought. Because in his mind, none of that mattered. What mattered was signal. Here is the concept Jobs understood that almost nobody else did. Every person alive is swimming in two things at all times. Signal. And noise. Signal is the three to five things that absolutely must get done today. Not next week. Not next month. Not someday. Today. The things that if done, move everything forward. The things your mission cannot survive without. Noise is everything else. The unnecessary meeting. The email that can wait. The social media scroll. The small talk. The market research nobody asked for. The decisions that feel urgent but are not. Everything that fills your hours without filling your purpose. Jobs ran at 80% signal, 20% noise. Every single day. Kevin knew this because Jobs would email him at 2:30 in the morning and expect a response. Not because he was unreasonable. Because for Jobs, 2:30 in the morning was still signal hours. He was still working. Still moving. Still locked in. The 18 hours he was awake were 18 hours of signal. Kevin says the only person he has ever seen operate at a higher ratio than Jobs is Elon Musk. Musk has almost no noise. Sixty seconds of every minute. Sixty minutes of every hour. Every waking hour pointed at whatever the signal is that day. And the results, like Jobs, speak for themselves. Jeff Bezos had his own version of this. He would not make a single decision after 1pm. Not because he was lazy. Because he understood that by afternoon, the noise had accumulated enough to cloud his judgment. His signal hours were in the morning. So that is when he decided things. And he protected those hours like they were sacred. Because they were. Here is the uncomfortable truth buried inside all of this. Noise is not always bad things. Sometimes noise is your family. Sometimes it is a friend calling to catch up. Sometimes it is a guitar sitting in the corner of the room. Sometimes it is rest. The people running at 100% signal, Jobs, Musk, the geniuses of history, paid a real price for it socially. Relationships suffered. Normal life suffered. Warmth suffered. Jobs himself was famously difficult to be around. But here is the question worth sitting with: Most people are not choosing between 100% signal and a balanced life. Most people are choosing between 30% signal and 70% noise. They are not sacrificing family time for focus. They are sacrificing focus for nothing. For scrolling. For distraction. For busy work that feels productive but produces nothing. That is the real problem. Kevin now tells every CEO he works with the same thing. It does not matter if you run an S&P 500 company or you are three weeks into your first business. The formula is the same. Identify the three to five things that must get done today. Not tomorrow. Not eventually. Today. Then protect those things with everything you have. If you can spend 80% of your waking hours on signal, you are operating at the level of the most successful people who have ever lived. If you drop to 50/50, signal and noise in equal measure, you will fail. It is, Kevin says, that simple. Jobs was not successful because he was a genius. He was not successful because he was charismatic or visionary or ahead of his time, though he was all of those things. He was successful because when he woke up every morning, he knew exactly what mattered. And he refused, sometimes rudely, sometimes brutally, sometimes at the cost of every relationship in the room, to let anything else in. Most people spend their whole lives reacting to noise and calling it work.

Everything in this matrix of light in which we live consists of a frequency. Every single piece of matter vibrates at a certain frequency, every blade of grass, every chair, every person we meet, every thought, every intention, every feeling. They all vibrate sometimes faster, sometimes less fast to project their matter. High vibrational matter turns into light. Low vibrational light turns into matter. The frequency is emitted by the body's own electromagnetic field - also known as the aura. The aura consists of electricity, magnetism & dielectricity and forms around our body like a torus field. In a healthy state, the entire aura can extend several feet and is very bright in color. In an unhealthy or weakened state, the auric field can be small and dull. Your aura is connected to the 7 energy centers of the body or the chakras, and is compromised of 7 different layers. Do you want to know more about it? Here you get the PDF:

And look what he's achieved" "Now, it's very awkward for him socially. Because noise is dealing with your family sometimes, saying hi to a friend, listening to some doom scrolling on social media that takes your mind. If you go back in history you're going to find that the geniuses of their time, we're close to 100% signal" "If you're going to be awake 18 hours and you've determined that there's three things you have to get done, you're going to get those done no matter what"

Every VC had a reason Vercel shouldn't exist. Guillermo Rauch heard a different reason from every investor he spoke to when building Vercel, and he kept going anyway. He joined us live at Mercury HQ in SF for Founders in Arms, and this was one of the sharpest moments in the conversation: the idea that consensus is a signal to walk away, not lean in. Full conversation with Guillermo Rauch (CEO, Vercel) on the latest Founders in Arms episode. Link in bio.

There's a profound elegance in watching gradient descent find the signal in the noise. This is a simple MLP with sigmoid activations slowly warping to approximate f(x) = 1/(1 + x²). Watch the loss curve right around epoch 400. That sudden phase transition where the network finally "gets it" and snaps into the Witch of Agnesi shape is incredibly satisfying to watch.

Steve Jobs was a terrible person. Kevin O'Leary hated him. Kevin O'Leary worked with him in the early 90s making educational software. He'll tell you that directly. "Not a nice guy. Not a nice guy." Jobs would stand in a room full of people and say: "I don't give a shit what the students want or the parents think or anybody thinks. It's what I want. They don't know what they want till I tell them what they want." Kevin pushed back. "Steve, you sound like such an asshole." Jobs didn't blink. "Now, are you making money with me? Am I your fastest growing OEM? Have we not been wildly successful and continue to be?" Kevin admitted he was right. "Then fucking shut up and do what I say." Kevin understood later: Jobs wasn't just being difficult. He was operating on a completely different signal-to-noise ratio than everyone else in the room. His definition of signal was ruthlessly narrow: the three to five things you must get done in the next 18 hours. Not next week. Not next month. Not next year. Just today. Everything else, every meeting, every opinion, every distraction — was noise to be eliminated. Jobs ran at 80/20. Eighty percent signal. Twenty percent noise. Kevin knew this firsthand. Jobs would email him at 2:30 in the morning. No texts back then. Just an email sitting in your inbox at 2:30am, expecting a reply. "He was right. He was right." The only person Kevin has ever seen run a higher ratio? Elon Musk. "He has no noise. He does not deal with noise. He is 100% signal — 60 seconds of every minute, 60 minutes of every hour, the 18 hours he's awake. It's all signal." Media: Aspire

Kevin O’Leary reveals Jeff Bezos doesn’t make decisions after 1 PM "Bezos will not make a decision after one in the afternoon because he felt that the noise was too high. The signal for him was in the morning hours" "This is a crucial aspect of success that I now understand defines an entrepreneur. A man or woman that understands a signal noise ratio and focuses on that, they'll be successful" "The ones that can’t get down to a 50/50 signal noise, they'll fail. It's a very simple concept. You have to decide how much signal you need to get those three to five things done"

WINTERS: Rand Paul, I get it. You’re working an uphill battle. But you’ve had 4 years to make the case and it was still all over the place. I know these docs better than anyone and I struggled to follow it. Separate the signal from the noise. The noise is clapping like seals at clips of Fauci. The signal is that Fauci was the tip of the spear and the chosen poster child for a scientific industrial complex in Washington aided and abetted by the Chinese communists. Natalie Winters
