Hello friends!

The Serenity operating system turns 1 year old today. I’m counting
from thefirst commitin the
git repository,
on October 10, 2018.
Parts of the code had been around for a while before that, so this
first commit was really about putting everything I was tinkering
with into a shared repo.

Anyways… we have to start somewhere!

NOTE:This web page is very light on HTML/CSS features so that it
can be rendered by Serenity’s own Browser!

In the beginning there were four components:

  • The AK utility library
  • An ELF executable loader
  • An ext2 filesystem parser
  • A simple GUI toolkit on top of SDL

These were just some little C++ projects I had been tinkering with
after installing Slackware 11 on an old PC to do some hacking.
None of them were very mature, but it was fun, and I was in a place
where I needed to do some programming to find myself again.

Here’s how the ext2 filesystem parser looked like when running:

    ::>cd /home/andreas
    ::>ls -l
    [VFS] ls ///home/andreas ->ext2fs 01:00000017
    01:00000017 drwxr-xr-x        1024 2018-10-08 13:47:04 ./
    01:00000016 drwxr-xr-x        1024 2018-10-02 23:43:49 ../
    01:00000018 -rw-r--r--          18 2018-10-02 23:44:09 file1
    01:00000019 -rw-r--r--          18 2018-10-02 23:44:14 file2
    ::>  
   

2018-10-10:The first ever “screenshot” of what became Serenity:

SerenityOS: From Zero to HTML in a Year 1

I imported a little x86 kernel I had been working on earlier in
the year. It was a piece of crap, but it was a place to start.
I originally had some weird idea that kernels should be written
in C, so I had tried to write in C, but I thankfully realized very
quickly that I was being silly. :^)

2018-11-08:Serenity running inside a virtual machine:

SerenityOS: From Zero to HTML in a Year 2

I kept working on the GUI toolkit on my Linux system, while also
developing the standalone system. This is how far I got with the
GUI while it was still sitting on top of SDL on Linux:

SerenityOS: From Zero to HTML in a Year 3

I then decided it was time to get this running on top of Serenity’s
own kernel. A day later, I saw this running in a VM for the first time.
It was the most beautiful thing I had ever seen.

2019-01-10:Serenity booting into a GUI for the first time:

SerenityOS: From Zero to HTML in a Year 4

I started working on a userspace API for doing GUI stuff. The original
version was a monstrosity with the window server running in the kernel
and processes making syscalls to create windows, etc.

2019-01-21:Seeing how many “guitest” processes I can spawn:

2019-02-28:Early version of ProcessManager (today called SystemMonitor):

Somewhere around here I figured it would be cool to add networking support,
so I started building a network stack.

2019-03-15:The first thing I did when TCP kinda worked was build an IRC client:

And with that, this little screenshot tour of the first year of Serenity is over.

If you would like to see more, I’ve also been making regular monthly update videos
throughout the year:

To all the boys and girls who have helped out in the last year, with code, bug reports,
docs, commenting on videos, e-mailing, hanging out on IRC, retweeting, telling your friends, etc,
thank you! I’m so grateful for all the love this project has been getting.

And also, a hugethank you!to everyone who has supported me via
Patreon
and other donation methods! It’s my dream to turn this into a full time show some day,
and you’re a huge part of keeping that dream alive. 🙂

Let’s see what we can do in year 2!
