This is wonderful news. Spiro splines are very cool, but I never considered them a real option for any projects I was working on because of the licensing issue. Hobby splines were the patent unencumbered next best choice as far as I could tell, but Spiro semantics always seemed incrementally preferable.
Raph's thesis on splines is a fun read:

- scardine 7y agoCan you comment on the advantages of this implementation comparing to the one used in Inkscape or other popular software?
- raphlinus 7y agoI'll be giving at talk at Libre Graphics Meeting in a couple weeks on exactly this topic. I'll make the slides available as well. Hopefully they'll make the front page of Hacker News also, as that seems to be a thing these days for my work :)
- scardine 7y agoCool, looking forward to the talk. My first job as a software developer was writing AutoCAD extensions (in "AutoLisp" so you can guess how old I am). Even if I don't work in the field anymore the topic is still fascinating for me.
