At first, the videos seemed a bit weird and I didn't quite get where you are heading with everything, but after the last two videos it's been getting quite interesting to follow! I hope you are making more!
Hi! and thanks!
I agree that the concept in this one wasn't as well explained as other ones. If you've got an if statement, like "if (condition) { doSomething(); }", the idea I forgot to explain is that it's the same as "if (!condition) { goto Skipped; } doSomething(); Skipped:" In a nutshell, in assembly, you skip over the code if the opposite condition is true.
As for device I/O, I'll eventually make an OS development tutorial, but it's quite advanced, and not something for the faint of heart. As I found out, you can accidentally wipe out the content your harddrive pretty easily. I wiped out my partition table a couple months ago and spent maybe 10 hours recovering it. :(
Inventor IDE should work on Linux, though it'll build Windows executables, since I don't yet have support for ELF file output. I'd really like to get this and Mach-O format working, 'cause then it could assemble the same code for Windows, Linux, or Mac with the click of a button. I've tried the image program in WINE, though it only half-worked half of the time, and different parts would succeed when it half-worked, hehe. If you try it out, please let me know whether it works for you. :)
finally you are back
keep up the great work
your tutorials are awesome
you are a little too fast
so consider slowing down and explain the concepts a bit more
also how about a tutorial teaching getting input from a device and similarly output to a device in assembly
do i ask for too much
probably
anyway keep up the excellent work
one last thing can i use inventor in linux
