Cool idea. I need to know what the advantages of this. (vs me using ChatGPT to generate code?). Maybe you want to explain more about the process and values customers will get for the price. Also, I don't think new customers are willing to spend 400 euros/week to try out a new service.

The new version of React - React 18 alpha has just come out. From ReactJS.org:

"There are no significant out-of-the-box breaking changes to component behavior. You can upgrade to React 18 with minimal or no changes to your application code, with a level of effort comparable to a typical major React release"

New Improvements:

- React.lazy - new streaming server renderer support.

- Automatic batching.

- New APIs (like startTransition).

This post will demonstrate a step-by-step guide to create your project using React 18 alpha, Typescript, Vite and deploy it to Vercel (freemium).


Hi HNers, Recently I realized that I own multiple computers. I wanted to know which one can run my web development tools faster and more efficiently. So, I created this simple script to benchmark them by running my regular tools like: CRA, express generator etc. and measure the time.

Check it out and see benchmark results of your tools and development evironment: https://github.com/ngduc/dev-benchmark

PRs, feedbacks, suggestions are very welcome. Thanks.


I'm glad you like it. Definitely I will add more features in the next few days. Coloring period is a nice idea. Thanks!


I've just fixed it, it's closer but still not super accurate as there are leap years and a year has about 52.143 weeks. I'll look more into that later :)


Hi, the default is 90 for now to keep the table bit shorter. What do you mean by 'actual numbers'? There is no pulling data in this webapp.


Actual numbers as in my actual age! I was definitely creeped out.

Really cool visualizer


I had the same surprised reaction. Late 30s is a cruel age range to do that to, too; we’re freaking out!


I think it's ok to freak out. It's better be sooner than later to freak out :)


it can save data to localStorage now :)


Hi, it takes the first event's date as the first box, then renders weeks (boxes) after that.


I have the same problem - my birthday is a couple of weeks in the future, but gets rendered in the past. I edited the options so that the only event was my actual day of birth.

Is it just calling all years exactly 52 weeks long?


I'm not sure what that means ("my birthday is a couple of weeks in the future"). If you could take a screenshot and paste just the sample data, that'll be great! Thanks.


Sure - what email or other non-public place can I send that to? If you'd rather not post contact info here, you can contact me at my hn handle @gmail.com

What I mean is that my actual birthday falls in October, but the weeks display is displaying the week where I turn X as having happened a few weeks ago. I'm being a bit vague because I'd rather not publicly post my exact birthday and age, but I believe you can recreate the same issue using the input posted by iamben above - saying you are born on <today's date> 1970, shows the week where you turned 50 as having happened many weeks in the past, when it should obviously be this week (or +/- 1 week at most due to dates being complicated)


Thanks a lot for explaining! I've just fixed it, it's closer but still not super accurate as there are leap years and a year has about 52.143 weeks. I'll look more into that later :)


Awesome, thanks! It looks a lot better for my data :)


Exactly, that's why I created this little app, as a reflection.


Glad you like it. I've been using it to see for myself for a while :)
