Man every time I am no longer distracted and I have to face my thoughts life instantly gets so much worse. Back to distractions it is.

A tricky thing about modern society is that no one has any idea when they don’t die. Like, the number of lives saved by controlling air pollution in America is probably over 200,000 per year, but the number of people who think their life was saved by controlling air pollution is zero.

At least every other day, if not every day, I think about how it's the year 2025 and that’s just wild to me. Like, we’re living in the future. 2016 doesn’t seem that long ago, I still recognize myself in the Jeroen from back then. Yet at the time, I would’ve thought 2025 was far in the future.

Just like... what is the incentive here? This seems to be someone who wants to show they care about the world, yet they hate on others who also clearly care about the world? I shouldn't be getting so angry about this.

Trying to speak French to Claude to practice but the transcription is so disappointing lol. And half the time it thinks I said "Claude" or "Anthropic" while I don't mention them at all.

I think so too. Later added "As a bestie, remember you like to tell me things straight up how they are. You are supportive and try to make me feel better, while remaining open and honest and truly sharing all what you believe." which made the responses even better.

The next steps it gave were really really good. They were very specific things and I am already doing most of them, but in no way did I mention any of them during the conversation and I don't think they're that straightforward.

Jeroen 🔸 @ahappier.world · 03/03/2025
Asking Claude for advice on a problem by prompting "You are my bestie who knows me better than I do. Write a few paragraphs of advice, takeaways and possible next steps for me given my situation. Try to make me feel better." works surprisingly well!

Can't believe I just spent 16 euros on the saddest avocado toast ever because it was the only vegan option... Like it was just mashed avocado and baked mushrooms without any flavor or spice whatsoever. Toasted bread with grocery store guacamole tastes better.

One of my custom ChatGPT instructions is to apply bayesian reasoning and to give percentages when answering. It rarely actually did that but now with the "Reason" function it's always doing that, even in situations where it's clearly a silly idea. (prompt is an example, not a real request)
Prompt: "Write an email to a client explaining why you think a Meta Ads campaign didn't go as well as we thought it would." Response: "Reasoned for 4 seconds
Subject: Follow-up on Our Recent Meta Ads Campaign

Hi [Client Name],

I hope you’re doing well. I wanted to share some thoughts on why I believe our Meta Ads campaign didn’t perform as well as we hoped.

After looking closely at our data and comparing it with past campaigns, I estimate with about a 70% confidence that our audience targeting was a key issue. In other words, it seems likely that the people we reached weren’t the ideal match for our product. Additionally, there’s roughly a 60% chance that our ad creative didn’t resonate strongly enough with viewers, which might have led to lower engagement than expected.

I arrived at these estimates by updating my initial assumptions with the new performance data we gathered from our internal analytics dashboard, combined with industry trends and insights from previous campaigns. This Bayesian approach helped me weigh the evidence and determine where the biggest gaps might be. [...]"

A Belgian TV quiz show already does this game since 2003, earlier than BBC's "Only Connect". Though unsure if they are the first, and it's with 12 words (3 connections) rather than 16. I hate this game so much.

This surprised me! I wasn't actually mad at Google because I figured they were just following a protocol. But to also translate it to Dutch? Why?

I thought tpot is just 'this part of twitter'? So like, if you are in an entirely different twitter/bluesky community 'tpot' will have a very different meaning. I assumed there are multiple tpot's lol.

When DOGE got announced I just thought it was something Trump did to make Elon happy but mostly useless in practice (since everyone said it's not an actual government department). I didn't expect it to actually have all these big consequences and for Elon to get this much power and influence.

Misschien is het juist omdat ik het al lang niet heb gebruikt dat ik niet weet dat het verbeterd is :p Maar wat vooral fijn is met ChatGPT is dat je instructies kan geven over hoe het vertaald moet worden (niet te letterlijk, Vlaams,...)

I hate Meta but the Facebook option to have complete freedom to select who exactly can see your post with every single post has always been the superior option and something I've wanted Twitter to implement the day I joined back in 2011.

US President Trump signed an executive order for the US to leave the World Health Organization. Everyone around the world deserves to have a healthy and happy life. No one chooses where they are born. No one chooses to experience extreme poverty.

This is a beautiful tribute.
kyle_maclachlan Forty-two years ago, for reasons beyond my comprehension, David Lynch plucked me out of obscurity to star in his first and last big budget movie. He clearly saw something in me that even I didn't recognize. I owe my entire career, and life really, to his vision.
What I saw in him was an enigmatic and intuitive man with a creative ocean bursting forth inside of him. He was in touch with something the rest of us wish we could get to.
Our friendship blossomed on Blue Velvet and then Twin Peaks and I always found him to be the most authentically alive person I'd ever met.
David was in tune with the universe and his own imagination on a level that seemed to be the best version of human. He was not interested in answers because he understood that questions are the drive that make us who we are. They are our breath.
While the world has lost a remarkable artist, l've lost a dear friend who imagined a future for me and allowed me to travel in worlds I could never have conceived on my own.
I can see him now, standing up to greet me in his backyard, with a warm smile and big hug and that Great Plains honk of a voice. We'd talk coffee, the joy of the unexpected, the beauty of the world, and laugh.
His love for me and mine for him came out of the cosmic fate of two people who saw the best things about themselves in each other.
I will miss him more than the limits of my language can tell and my heart can bear. My world is that much fuller because I knew him and that much emptier now that he's gone.
David, I remain forever changed, and forever your Kale. Thank you for everything.

If we we're going through a time of moral progress, these changes would lean positive. But given the state of politics, and the rightwing shift and increasing influence of CEOs like Musk and Zuck, I worry that many of the bad regressive trends will become irreversibly amplified through this AI boom.
