How to run Linux on Web, I believe that many inexperienced people do not know what to do. Therefore, this paper summarizes the causes and solutions of the problem. Through this article, I hope you can solve this problem.

A programmer named Fabrice Bellard wrote a Javascript to launch Linux in the Web browser (the original page, I put this page iframe below), currently, you can only use Firefox 4 and Chrome 11 to run this Linux. This is not a fake imitation of Linux, it is actually running a Linux. The move has also attracted a lot of attention, including Brendan Eich, the founder of Javascript.

Subsequently, Fabrice Bellard issued a related technical note: http://bellard.org/jslinux/tech.html, from which we can see:

This simulator is written entirely by Javascript

The CPU simulator uses QEMU (close to the original 486) and has made some changes to install Linux.

Javascript's terminal could have used termlib, but he wrote one himself because the button of OS is different from that of Web browser (here).

Linux uses the 2.6.20 kernel, compiled and configured here, and made some minor changes.

The disk uses Ram Disk and is loaded at startup. Its file system is generated by Buildroot and BusyBox.

There is a hello.c program in the Home directory, which you can compile using TinyCC (tcc, see Cool Shell article)

I have these feelings from this matter.

Running a Linux operating system on Web is not a problem. So is there anything else you can't do on Web?

Linux is really high performance, and it doesn't feel slow to run under Javascript.
