Happy BitBLT Day to all who celebrate https://www.jwz.org/blog/2025/11/happy-bitblt-day-to-all-who...
Reminder to right-click, click "Get Clean Link", then open a new tab and paste to avoid jwz's anti-HN referral tracker.
oh, uh, can jump from mastodon then where I copied the link from, sorry https://mastodon.social/@jwz/115578171906975865
He refers to byte magazine's article on bitblt: https://archive.org/details/byte-magazine-1981-08/page/n185/...
Also XScreensaver's Blitspin hack: https://archive.org/details/byte-magazine-1981-08/page/n201/...

What does this guy have against HN?
first time i get "*ickrolled" on HN
Didn't you read the page? "A venture capital company's fan club. Finance-obsessed man-children making the world worse." A previous version said, "A DDoS made of finance-obsessed man-children and brogrammers."
Worked for too many VCs.
Interview with Dan Ingalls here where he talks about inventing BitBlt

First time I heard of BitBLT was the Win-11-breaking-ColorForth discussion at https://news.ycombinator.com/item?id=45953001
43FF's Law: You can measure software complexity by the number of nested for-loops.
The first for-loop appeared around in 1957 in FORTRAN.
In 1975, Smalltalk having two nested for-loops was a grand breakthrough.
Now in 2025, our most advanced AIs run on for-loops nested 6 or 7 deep. Who knows what the future may hold?
Fortran used to have DO loops. It still does, but it used to, too.
Algol's the one with FOR loops.
A routine often used for intellectual property theft*.
