Yay!

I accidentally threw away the source code, though.

What? You accidentally deleted your own source code?

Use a recovery software, this works only if you deleted all with recycle bin of Windows

recovery software can recover files regardless of how they were deleted, it doesn't have anything to do with the recycle bin.

it basically finds sectors that were freed but not overwritten, in hopes of recovering some files information.

It might be worth adding that recovery software, depending on the method used, doesn't always work too well with text files (such as software source code). If it recovers the files using left-over structures in the filesystem, it will know where the file is supposed to be and how long it is, but as most modern filesystems overwrite these structures for security reasons modern recovery software tends to depend more on the structure of the file to determine where it starts and ends (this only works if the file isn't fragmented, of course). This doesn't work with text files because, unlike common office and media file formats (for example), they don't have standard headers/footers/blocks/size fields that can be used as a "signature" to locate the file and obtain information about it.

Not *quite* true for source code; C files, for example, will have a bunch of "#include" near the beginning most of the time.

Although that's still somewhat "fuzzier" than locating a true header and using the structure of the file to determine its size.

Basic OS Update:
1.Finally finally finally managed to finish the backspace, was having an awful bug.
2.Finished command framework, added help lists and descriptors.
3.Finished scrolling, I decided to clear the entire screen.
4.Implemented couple of commands.
5.As you can see my PIT and uptime counter both work.
6.Conclusion: terminal framework is finally "finished" and ready to be called stable.

Finally, someone has given his OS the same name as I have , but it was centuries ago.

Well, calling it Basic OS is very original

Backspace? You mean you make mistakes?

Here is Obsidian OS with a new window design. I have also removed almost all graphical applications, for the moment.
I'm focusing now on OS stability and I'm also trying to make the OS much simpler. GUI apps will be re-added later.

Yeah, it was my fault.
Also why does the font seem so small?

I like this one better. Stick with it.

Yeah, me too. It remind me twm, an old window manager on Unix/Linux:
