Hey @eex97623.bsky.social you running #Cobolsky too?
Running some first tests on @formerlab.bsky.social account.
Cobolsky, a real @bsky.app client, frontend is GnuCOBOL
Read timeline, compose posts, like, view threads, and
check notifications...
All from a language designed in 1959

Learn a lot of very obscure acronyms. Learn to mix and match 70s and bleeding edge tech jargon.

Solved it with an edge KV and a K8s gnuCOBOL MLOPs pipeline"

Another historic Cobolsky milestone 😂👍
Former Lab just posted a Floyd-Steinberg dithered image to Bluesky via Cobolsky, a GnuCOBOL AT Protocol client.
Bill Atkinson's portrait, run through his own Apple 1984 algorithm, sent from a 1959 language over a 2026 protocol.

Bill Atkinson, 1951-2025. MacPaint, QuickDraw, HyperCard. His dithering algorithm, 1984. His portrait, run through his own algorithm in COBOL, posted via Cobolsky + AT Protocol, 2026. The forgotten algorithms are not dead. CC-BY-2.0 Jay Cross @atproto.com @atprotocol.dev

It probably would be less prone to mistakes if they used GnuCOBOL, as this translates COBOL into C before compiling according to the docs. Not sure whether all possibilities are covered, and you can run it on Gnu/Limux, BSD, Windows or MacOS… Not the mainframes.
