I am on it

Thanks a lot!

AI generated or not, the target device was the PC, but the point still stands. Anyway, you have a pause button that you can click to pause the flow. On PC you might not use the mouse that extensively so pressing Space saves time. It's just a nitpick that I haven't removed the Space reference on mobile, but you can still pause the flow.

haha sorry about that :D

It's meant for people that do not have extensive knowledge over how chips are made. I doubt majority of the people know what lithography means, let alone DUV EUV etc.

I am not even asking for donations, what are you talking about?
laurentiurad··on Learn how chips are made with this Rollercoaster Tycoon-inspired animation
I created Chip Tycoon as an animated visualization of the semiconductor manufacturing process, inspired by the classic isometric style of RollerCoaster Tycoon and Zoo Tycoon. Rather than reading through a long article, you can watch silicon move through the major manufacturing stages—from wafer fabrication and lithography to packaging and testing—in a miniature factory.

My goal was to make one of the world's most complex manufacturing processes easier to understand by turning it into something that feels alive and enjoyable to watch.

laurentiurad··on Show HN: I made a game where you build a CPU from logic gates
I really don't appreciate this Reddit-like snarky attitude and I usually do not respond to people like you and to ill-intentioned messages like this one, but this time I will, since you accuse me of scamming people, which is a big deal.

The post is about the game. When clicking on the Browse button and assuming you can read, you will see a collection of well-crafted products. I am not selling those myself. The website does not process payments, does not ask for donations, nothing like that.

Saying that the ALU example does not have tests is just a lie. I am not sure if you are a liar, or just frustrated about something, or maybe you're having a bad day, but for a person bragging about being an ex-employeeID at a big-tech firm and a GH-contribution-green-dots chaser, you should be more humble and think twice before accusing someone of doing illegal stuff.

Thanks! Just added the possibility to skip between levels. Also you can wire without manually switching between wire/select buttons.
laurentiurad··on I made a game where you build a CPU from logic gates
Thanks a lot! Will do!

Thanks a lot for your time in providing the feedback! I think every point is valid so will try to implement them.
laurentiurad··on I made a game where you build a CPU from logic gates
Noted. Will add a skip mechanism too.

Thanks for the feedback! I am curious what made you think it's AI? My experience with using LLMs is that they usually use dark mode + neon + gradient a lot, but nothing like the design you see on my website. I'd highly appreciate if you share what elements you thought as being vibecoded or made with AI.

Thank you for the feedback! Will implement it today
laurentiurad··on I made a game where you build a CPU from logic gates
A good point. I will change it!

Thanks for the feedback! Will definitely look into simplifying it

You can paste text and immediately see how it's split into tokens, along with token IDs, counts, and other details. It's useful for understanding why prompts cost what they do, why context limits behave the way they do, and why models sometimes split words in unexpected places.

I made it because I kept explaining tokenization to friends and realized there wasn't a simple, interactive tool that focused on learning rather than documentation.

I'd love feedback on:

Features that would make it more useful UI improvements Bugs or edge cases you've found

Hope it's useful!

laurentiurad··on Is AI hype cooling down? I built a data-driven dashboard
Over the past few months, I've seen more people claim that AI hype is fading or that we're entering another AI winter.

I wanted to see if the underlying data supports that narrative.

I put together a dashboard that tracks several indicators that are difficult to fake:

Hyperscaler AI/data center capital expenditures GPU deployments Data center construction Power demand and electricity generation Model usage and inference economics AI revenue and adoption metrics

If there are additional datasets you think should be included (or if you spot something misleading), I'd love feedback.

Run a prompt, set your temperature and top_p parameters and watch what happens.

Thanks! Will work on that!

but how can you know the author used AI in the first place, and more than that, if he indeed did it, that he didn't check what the LLM did?

how do you know it has been vibe-coded? And why does it matter?

thanks a lot! Will update this on the daily basis.

You are right, one might happen before the other one. However it's impossible to measure when the bubble might pop, whereas looking at how much money hyperscalers and governments put into this might provide a quantitative metric.

nitpick about what you said: you don't wanna postpone that plan too much. At 40 you won't have the energy to keep up with the needs of the kid. You will hate your life and you'll make a ton of mistakes. I had them young, and my career and financial situation weren't affected at all.
laurentiurad··on I built a page showing the likelihood of the AI bubble to pop
I recently built this page which uses data like CapEx from the quarterly forms of the 5 biggest hyperscalers, or how many data centers are being built, and it calculates a composite index showing how likely it is for the AI bubble to pop.

I cannot agree more. Useful idiots and people working in private equity which have a direct financial interest to hype this tech.

It's tech bros like you that are to blame for the shortage of radiologists supporting statements since 2016 which state that radiologists will disappear. Your great SOTA LLMs will tell you to walk 5 mins to the car wash instead of taking the car.
