I just uploaded my threads over the past week on Expect to: https://adrian.geek.nz/gnu_docs/testing
I'll have Deja GNU up next after I study Signed Distance Fields, and I have previously about Haskell's unittesting framework: https://adrian.geek.nz/haskell_docs/haskell-build.html
As for my subsequent plans...
Next: FreeType SFNT support
Then: Solr's plugins system (in place of revisiting BinUtils)
After: FreeType smoothing
Later: GNU Multiprecision
