Work in progress GUI.

Beautiful! Mind if you PM me that background?

How are you setting the graphics mode? Do you use hardware acceleration? It looks very pretty!

@omarrx024: I have sent you the background over PM.

@nakst: currently it sets the video mode using BGA, but there is an abstract interface over graphics hardware, so I can port it to use VESA by simply writing a new driver. Hardware acceleration is not yet supported.

my latest purchase is a "primer on memory consistency and cache coherency" by Daniel J. Sorin, Mark D.Hill and David A. Wood, after a lot of searching on topics i.e. memory cache coherency and related topics, I finally received, went through few chapters so far. I already think it is well-written not too technical yet complicated enough to be a graduate course level study.

My x86_64 operating system (not much more than a basic kernel and a kernel-space C library so far)
As is obvious, it's called "Thoth".

I've made some progress on my operating system and it's now able to load files from the hard drive on ext2 volumes! (that said, my VFS needs some serious work). Using the STB truetype library I've created a little test program where you enter the path of a font, and then type a message with it, which will be converted to ASCII art. I think it's pretty cool :3

Cool. But why you have a "if the kernel hangs here bla bla bla" line? Why not use the system test and display that message only when needed? This is my OS on 31 MB of RAM, so it crashes with error.

This message is printed just before I switch to preemptive scheduling. Since I can't think of a processor speed independent way to test if the PIT is working correctly, I just added in that line. I'll probably remove it in the future - most of the logging stuff now is temporary and for debugging reasons only.

I like how the 'q' looks in your font

It's stupid, I know.

It's in the source code and in Git (I'd just like to know what the program that generated it looks like, presumably randomly):

why i can not open your website? I want see your source code, have you put your code on github?

I've noticed that too. catnikita255: your site is down, Chrome says: ERR_NAME_NOT_RESOLVED.
