I'm back with a new post of the Amiga Machine Code Course. This time it's about Bresenham's line drawing algorithm. Both it's history and how it's implemented in the blitter. Read the gory details here! 😛🙂#Amiga, #RetroCode markwrobel.dk/post/amiga-mac…

Nice read on Pfizer vaccine's genetic code. Masterful strokes include sub'ing modified U bases Ψ to evade the immune system on way in, and sub'ing two amino acids so the spike freestands. Nice reminder that great science stands on the shoulders of giants. berthub.eu/articles/posts…

Anecdote: For 15 years floppy disk copy protection was fun cat+mouse hackery (Apple2, C64, Amiga; I was friends with the XCopy guys+I did 'Cyclone' hw copier) with lots of clever/complex tricks (sector sync, errors, long tracks, fat tracks, short tracks, 'weak bits' etc etc)...
There we go, the blog post for the dist blog.defence-force.org/index.php?page… The complete project source code is available on Defence-Force's SVN server: svnhead.defence-force.org/public/atari/t…
1/ @mark_wrobel In markwrobel.dk/post/amiga-mac… "The Code", is that the complete source code, including system inits, or just the effect itself? Just asking because my complete #atari #ste implementation takes 435 lines of code, including comments, inits, overscan, incbins, etc...
@mark_wrobel @kamelito Technically it works more or less the same as on the amiga, except here it's the cpu that plays the role of the copper, by synchronising with the display and changing the video registers on the fly, wait a bit, do it again, for all the lines of the screen.
@mark_wrobel Nice writeup! The copper was the main inspiration for the video logic in the MC1 computer (custom FPGA SoC). Not much material available yet though. github.com/mrisc32/mc1
