Linkedin’s behaviour trick

i don’t know whether it was by design or not, but linkedin’s connections viewed your profile keeps changing the time frequency between (1 week,past 15 days and a month).
The side effect of it is that there are times i click on it thinking there has been a new visitor. Ofcourse there wasn’t, the number count changed only because the frequency changed, by whatever linkedin algorithm uses.
Anyway, the real reason this is beginning to annoy me is that facebook used to do tricks like these.. can’t remember specifically which, but they used to use tricks that entice you into clicking/reading/generally spending more time on their site.. Ultimately i ended up quitting facebook, when i realized it became a huge time sink. In contrast i kinda like linkedin, and don’t want it to go that way….
Infact one thing, that helped me let go fb easily was the absence of recommendations from friends. Infact the only reason am holding on to my orkut account is the same..
Either way i think google plus misses a trick by not putting up one of those options..

Documentation as a deciding factor

Using the availability/non-availability of good documentation as a deciding factor to choose your library is not a universal rule..It’s a good rule of thumb, but not always meaningful. It’s meaningful only in cases where you expect quite a lot of developers using that library to extend your application/tool. Just realizing going with fabric for a ssh connection pooling library(bcoz it had a nice Documentation) is pointless.. it’s seems to have trouble handling thread-safe sessions..
