Leo-thorne··on Do the simplest thing that could possibly work
We once rebuilt an old system and went with the simplest thing that could work. It ran great for the first few weeks, but then all kinds of edge cases started creeping in. We ended up spending more time patching things up.
Leo-thorne··on A teen was suicidal. ChatGPT was the friend he confided in
Reading the full complaint really hit me. This wasn't just a kid talking, he was asking for help. The model gave smooth replies, but it didn’t really understand. It sounded like it did, but there was no feeling behind it. For a 16-year-old, that kind of response might have felt like someone truly listening.
Leo-thorne··on A small change to improve browsers for keyboard navigation
I’ve always found Firefox’s / quick find feature incredibly useful. But having to click on a link after selecting it always felt awkward and interrupted my flow. This little tweak is brilliant because it removes that extra step with just a few lines of code. If browsers allowed links to activate automatically once selected, navigating with a keyboard would feel so much smoother. I sincerely hope that becomes a standard feature one day.
Leo-thorne··on Building the mouse Logitech won't make
I’ve long been a fan of the MX Anywhere series. They’re light, reliable, and the side buttons make web browsing much smoother.But recently, mine started having sticky buttons and the grip began to peel. I tried fixing the micro switch myself and it turned into a real headache. Now I’m debating whether fixing it is worth the effort or if I should just grab a new one. What I really wish for is a mouse design more like mechanical keyboards modular parts, replaceable shells, customizable buttons. That kind of setup would finally make me feel like my mouse is meant to stick around for years, not get tossed at the first sign of wear.
Leo-thorne··on How to stop feeling lost in tech: the wafflehouse method
I’ve felt pretty lost before too, like stuck in this maze of endless paths. That line about not chasing tools but getting closer to the person you want to be really hit me. A lot of times it’s not that we don’t plan enough, it’s just that we rarely slow down and really listen to ourselves. This approach feels simple but grounding.
Leo-thorne··on Encrypting files with passkeys and age
This is a pretty cool idea. Using passkeys to encrypt files means you don’t have to remember passwords but still keep things secure. What I really like is that each file gets its own key, so even if one gets exposed, the others stay safe. If this kind of setup gets integrated into tools we use every day, like photo apps or cloud storage, it could be really useful.
Leo-thorne··on I'm done with social media – Or: why I have a blog now
I’ve been using social media less and less over the past few years. Especially short videos, they just make my brain feel foggy. At first I thought it was just distracting but later I realized it was affecting my mood and focus. Now I mostly use it to post photos and write more on my own blog, mainly for people I know. There is less interaction but it feels a lot more peaceful.
Leo-thorne··on Measuring the impact of AI on experienced open-source developer productivity
I really admire stories like this. Reaching $1M ARR without any funding is rare and feels real. It shows what building something truly takes. Late nights, tough moments, losing users. It's not about big bursts of growth but staying consistent, solving real problems, and growing revenue little by little. There's a lot to learn from that.
Leo-thorne··on AI note takers are flooding Zoom calls as workers opt to skip meetings
I use AI to take meeting notes too, and it really makes things easier. I can focus more on listening. But sometimes it changes the vibe a bit, like we’re all just talking to a bunch of bots. Now I only use it when I’m leading the meeting, and I always ask if others are okay with it. The tool is helpful, but real human connection still matters.
Leo-thorne··on The new skill in AI is not prompting, it's context engineering
I learned this the hard way. Even a great prompt won't work if the context window is off. If key information is missing or important history is buried too deep, the model will still fail. Now I always explain the problem clearly and set the scene before letting the AI take over.
Leo-thorne··on I built something that changed my friend group's social fabric
I really like this idea, especially the music quiz and birthday reminder. I've been wanting to build a bot for my friend group that shows up now and then when things go quiet, just to gently remind us of something warm. It doesn’t interrupt anyone, but quietly adds a bit of connection to the group.
Leo-thorne··on Websites are tracking you via browser fingerprinting
I used to think incognito mode was enough, until I found out browser fingerprinting is even worse than cookies. It tracks so many tiny details that sometimes it can recognize you even after switching devices. These days, going online feels like being watched.
Leo-thorne··on Is there a half-life for the success rates of AI agents?
I’ve seen the same thing using AI for coding. It helps a lot at first, but after a while it starts doing weird stuff or undoing things that were already fixed. Now I treat it like a junior dev. I try to keep tasks small, reset often, and check everything. Still useful, just needs babysitting.
Leo-thorne··on 3D-printed device splits white noise into an acoustic rainbow without power
I used to think you had to rely on circuits or resonance chambers to split sound frequencies, so seeing this done with a 3D-printed structure really changed how I think about it.

It made me realize how little design attention we actually give to sound. Most of the time we just passively listen, without thinking about shaping the path of sound. If structures like this can be made smaller and more portable, I can see a lot of interesting use cases in phones or compact voice-controlled systems.

Leo-thorne··on Now might be the best time to learn software development
Now really feels like a good time to start learning how to code. I used to get completely lost reading documentation, but with Copilot, I just type a few lines and it helps fill in the logic. It feels like having a more experienced person sitting next to me.

That said, I still try to figure out the logic myself first, then let AI help polish or improve it. It is a bit slower, but when something breaks, at least I know why.

AI has definitely lowered the barrier. But whether you can actually walk through the door still depends on you.

Leo-thorne··on Ask HN: How to Deal with a Bad Manager?
I’ve been through the same thing where a good manager got replaced and I ended up stuck with bad leadership. At that point, I just focused on learning from coworkers and projects that still had value, and kept detailed notes on my own work to give myself some sense of control. When you can’t change the environment right away, staying steady yourself is the priority.
Leo-thorne··on Ask HN: How do I give back to people helped me when I was young and had nothing?
A lot of mentors helped me when I was completely lost, and at that stage I really had nothing to give back. Later, I just focused on doing my best, trying to make sure what they taught me actually got used, so their time wasn’t wasted. Every now and then I share some progress with them, and they always seem happy to hear it. And now I try to help the next group of people who are going through the same phase I once did.
Leo-thorne··on Humans have nasal respiratory fingerprints
I once went to see a doctor because of anxiety, and they had me try some simple breathing exercises. That was when I first noticed how much my breathing pattern changes depending on my state. Now whenever I feel tense, I consciously slow down my breathing and it actually helps me feel more in control. After reading this article, the idea of a breathing fingerprint makes a lot of sense to me. It probably reflects not just physical traits but also your current state.
Leo-thorne··on A receipt printer cured my procrastination
I used to sit in front of my task list and just stare at it. Then I tried the author’s approach and broke everything down into tiny game-like tasks. I printed each one on a little receipt printer. Every time I finished one, it felt like taking down a small boss, tear it off, and toss it. Suddenly the task list felt way less intimidating and much more efficient. Surprisingly, the ritual worked. I was able to stick to it and even started to get a small sense of accomplishment every day. Definitely more productive than my old habit of tackling huge chunks at once.
Leo-thorne··on A bit more on Twitter/X's new encrypted messaging
Yeah, it’s live on the mobile app. You have to be verified and both users need to follow each other. Once I enabled it, there was a little lock icon on the chat, but the UI didn’t really change much beyond that.
Leo-thorne··on Show HN: Most users won't report bugs unless you make it stupidly easy
Totally get this. I once spent days trying to get users to submit decent bug reports through a fancy form and got almost nothing useful. The moment we switched to a simple “click here to report” button with an optional note field, the volume and quality went way up. Simpler is better, especially when the user is already frustrated.
Leo-thorne··on A bit more on Twitter/X's new encrypted messaging
I tried X's encrypted chat last week just to see what it was like. The interface is clean and it works smoothly, but once I understood how it actually handles encryption, I stopped using it. If they hold the private keys and there’s no forward secrecy, it makes me cautious. It feels more like something that looks secure rather than true end-to-end encryption.
Leo-thorne··on Researchers develop ‘transparent paper’ as alternative to plastics
My mom’s been helping out at a small local shop, and they’ve been trying to move away from plastic packaging. They tried compostable films and recycled paper, but either the cost was too high or the materials just didn’t hold up well.

This transparent paper made from cellulose sounds really promising. If it can handle heat, looks good, and actually breaks down in the environment, that would be a big help for shops like theirs.

Has anyone here worked with this kind of material? I’d love to hear how it performs in real use, especially with things like liquids or anything sensitive to moisture.

Leo-thorne··on Machine Code Isn't Scary
Thank you very much for your reminder. The comment has been corrected.
Leo-thorne··on AI makes the humanities more important, but also weirder
I think you’re onto something. Maybe essay writing won’t disappear, but how we do it might change, just like how photography changed art.
Leo-thorne··on Machine Code Isn't Scary
I always thought machine code was something only experts could understand. But after reading this article, I realized the basic concepts aren’t that complicated, it’s really just instructions, registers, and memory. I feel like this has given me a clearer understanding when it comes to writing code.
Leo-thorne··on Autonomous drone defeats human champions in racing first
I’ve seen AI beat humans in simulations before, but doing it on a real track with the same hardware is honestly kind of amazing. What surprised me the most is they didn’t use any traditional flight controller. They just let the neural network handle the flying.

I’m really curious how this would perform in messier, less controlled environments.

Leo-thorne··on AI makes the humanities more important, but also weirder
AI hasn’t destroyed the humanities, but it definitely made things more complicated and harder to teach. I’ve seen students rely entirely on chatbots to write essays, and it really does make teaching harder. As the article says, we need to find ways to make AI and the humanities work together, not just hold on to the old way of doing things.
Leo-thorne··on My AI skeptic friends are all nuts
At first I didn’t think LLMs were that impressive, but ever since I started using them, I’ve pretty much stopped writing for loops by hand. It’s not that I forgot how. I just don’t feel like doing it anymore. The time it saves me on boilerplate lets me focus on other things. Sometimes the code isn’t perfect and I need to fix it, but it’s still way easier than starting from scratch.
Leo-thorne··on Show HN: I made a Zero-config tool to visualize your code
Tried this out today and it’s surprisingly smooth for a browser-based tool. The zero-setup part really helps. Would be great if the visualizer could also show how values flow across function calls over time, especially for recursive logic. That’s where beginners often get stuck.
