Repeates Measures MANOVA for Time*Treatment Interactions
...fferent mind-set behind their experiments than, say, an ecologist, who is interested in the effects of time per se, and not just the effects of a treatment. For example, here's my dataset, say, looking at plant height in cm with and without fertilizer Treatment, Time1, Time2, Time3, Time4, Time5 Fertilizer, 1, 4, 8, 10, 12 Control,1,2,3,4,5 Fertilizer,1,8,10,12,20 Control,1,3,5,6,6 Fertilizer,2,5,10,20,25 Control,1,2,4,4,4 Clearly there is a time*treatment interaction (just eyeballing the dataset) My question is, how does one set this up using the anova.mlm approach so that in the end...

Elliptic curves in tinc
In the past 24 hours multiple persons have contacted me regarding the use of elliptic curve cryptography in tinc 1.1 in light of the suspicion that the NSA might have weakened algorithms and/or elliptic curves published by NIST. The new protocol in tinc 1.1 (SPTPS) uses ECDH and ECDSA to do session key exchange and authentication, in such a way that it has the perfect forward secrecy (PFS)
