Mac OS for the Web!

Mac OS emulator on the Web

Hi,
I want to introduce my project, which I call Mac OS emulator on the Web. We have programs like Notes, Calculator, Terminal, VScode, and other apps and features on this website.

You can try it now!

I wrote this project by HTML, CSS, and JS.

I think if something does not start well, it may end well when you do your best. This project was something like that, it didn't start well, and it was simple, but when I continued on my way and didn't break the chain, I saw the fantastic progress.

This website has PWA (Progressive Web Apps), which with this feature we can install it on any operating system such as Windows, Mac OS, GNU/ Linux, and we can also use it offline :)

about me:
I'm a 14 years old boy πŸ‘¦
I'm interested in things related to computers and science.
I started my journey as a web developer in October 2020 and started learning web development from Documents, Udemy and Youtube.
I have been working on this project for about six months, and during this project, I learned many essential topics in programming.

This emulator is an open-source project on Github.
I would like to introduce this project and connect with the developers' communities.
I will be very happy if you comment on this post or help me improve this project on Github.

My Github Page: https://github.com/mhmdmhd6/Mac-OS-Desktop

This Website's link: https://mhmdmhd6.github.io/Mac-OS-Desktop/

Your Support in improving this project is a source of motivation for me.

Thank You.

One quick question. As there are only two apps available at the moment, I tested the Calculator app with 0.1+0.2 and I got 0.300...004, a common result we get in some programming languages. Just want to know how (and the best way) can we solve this issue when implementing a calculator app ourselves.

Hi,
This is a good point that I did not pay attention to it before.
When I saw your opinion, I first went to find out how this happens, which was interesting to me.

Then I thought to your question, how can we solve this issue?
At first, I thought we could round the number, but when I used the round method in JS, the result was zero! Then I searched it and realized that we can use the toFixed() method in JavaScript, when we put the digit on 1, the result is 0.3!

I want to know what is your answer to this question and is my answer correct?

Thank you very much for your excellent comment :)

Yes, toFixed() is the JS way to round a Number and obtain a string. It will work if we know the number of fraction digits. If we divide numbers like 1/3, toFixed(1) will result in an answer 0.3 with a huge deviation compared to something like 0.333333.
Actually I am also looking for a good answer to this question. But I do have a workaround: to use toLocaleString with an en_US locale and maximumFractionDigits specified as 16 or less.

That's right,
it's a great idea to use toLocaleStringwith an en_US locale and maximumFractionDigits specified as 16 or less. πŸ‘

Btw, awesome work. It really feels like macOS and is also running fast!
I've seen a Windows 10 web app here in dev.to before but it was a bit laggy.
When you are 24, you will probably be working at Apple.

Btw, I just checked your GitHub repo, and immediately I have two things in my mind.

  1. Why are there private and public keys in the repo source?
  2. I thought you did this by using React or some other modern development framework/library but you did this all by vanilla HTML, JS and some jQuery for dragging support. You must have a deep understanding on how website works.

Thanks :)

  1. For your first question, I had the mistake of adding my github's account private key to the repository source.
    now I remove them all.

  2. I'm glad about that :)
    I had no idea what vanilla meant πŸ˜…(of course, now I know).

you are 14? really?
btw, be careful on how you remove those private keys. one commit removing the files is not enough

Just change the keys if you've exposed a private key. As a general rule, never commit a private key on a public repository and really it's best to not ever and use something more secure like Hashicorp Vault or AWS's tools for secrets.

To OP: See this for GitHub's official guide about removing sensitive data: docs.github.com/en/authentication/...

"I had the mistake of adding my github's account private key to the repository source. now I remove them all."

I don't know why I can't press "reply" on your answer, but here:
Well you deleted them, but they are still in the git commit history se we can still see them, so either:

  • Remove your repo and make a new one with commits from scratch (new initial commit)
  • Revert all the commits up to here github.com/mhmdmhd6/Mac-OS-Desktop... (where you added the public/private keys and push -force back the repo)

I don't know git enough on the security parts, but if you don't want people to do bad things with your keys, invalidate them and generate them again (Idk how, sorry). :)

Hi, Try this.

parseFloat((0.1 + 0.2).toFixed(10))

You should use bigNumber to fix it. (Mathjs, Bignumberjs). This is my example: github.com/nguyenvannghi/calc-reac...

Changing the top-menu font will make it more realistic!

this is amazing, however i will recommend you to show the menu list when it is clicked instead of on focus.

Good job. Impressive and appreciated.
It is not a difficult project but not easy for your such age. I was only learning AppleSoft Basic (maybe you don't know it) at your age. jQuery is good for beginner. It was also my first library to start web programming. Next step, you can try one of popular frameworks, Angular, React, Vue.js, etc. They are so interesting and funny to play. You will love it.

Hi!

Very good work for fun...

If you really want to realize your project maybe you should base it on GreyOS. It is an open source Meta-OS (nothing related to metaverse, facebook, etc.). I have been developing this since 2013.

I am a professional enterprise architect and I'd love to help you Muhammad.

Please check the github.com/g0d/GreyOS for details and let's make something beautiful :-)

Congrats.
What I suggest to you is to check this repo: github.com/PuruVJ/macos-web
This guy already did the exact same thing but in Svelte with some improvements. So i think you can learn from it and also if you want, learn svelt!
The website that is hosted is: macos-preact.vercel.app/

This is amazing not only you're just 14 but also you're using only Js not modern framework for building this website.

Btw, there's a little bug in here, but keep going, you're really awesome.

In defense of the modern web

I expect I'll annoy everyone with this post: the anti-JavaScript crusaders, justly aghast at how much of the stuff we slather onto modern websites; the people arguing the web is a broken platform for interactive applications anyway and we should start over;

React users; the old guard with their artisanal JS and hand authored HTML; and Tom MacWright, someone I've admired from afar since I first became aware of his work on Mapbox many years ago. But I guess that's the price of having opinions.
