Hi guys, Studying more about wapbl, I saw It is a little faster than SU+J and so much more easy to implement, correct me if I’m wrong, please.
About a diff with working code, my next would be one with it, but not with the whole thing working, It was to be homeopathic. But now I have doubts whether to continue SU+J implementation or to implement WAPBL (more easy, cause Pedro had implemented in bitrig) Any suggestions? > On Sep 1, 2015, at 8:08 PM, Bob Beck <[email protected]> wrote: > > I would much rather see something llike wapbl ported than this..
