Even after fixing it, I'm still not quite sure why it said "I don't trust it." I think my code has trust issues.

I posted the full screenshot in the other thread, but it's only upon examination that I spotted this bug:

Image

The screenshot was actually taken on February 28th (so should display "2019-02-28")... I suppose the 0th day of March is kinda the same day as the last day of February, but obviously something isn't working right. The odd thing is that the date values are read directly from the RTC at boot time; maybe QEMU has a bug?

EDIT: Seems to be a bug in my epoch time <-> time and date conversion functions.

I know that screen well. That's what happens when you dump your 16-bit IVT table at memory location 0x00 to the screen. When you see the 3 horizontal lines and a bunch of 'S' characters, that's a good sign that you've tried printing a NULL pointer to the screen.

It's actually been a while since I've seen that screen, but it does take me back to my earlier OSDev days :)

Like an old song you haven't heard in a while...

When trying a simple print statement, I managed to get to this screen. How did such a small change fail so horribly. :shock: :shock: :shock:

Good to know.

Lots of these remind me of my Atari and MS-DOS days. :)

Keep the code for a screensaver -- xscreensaver did! :mrgreen: It looks a lot like like xscreensaver's "decay", but "slip" (slipped blits) is similar too.

Sadly this only a appeared when I moved the mouse, so this would be a quite pointless screensaver :roll:
