comment Mathematica gravatar engine?
Chuy, this is great thanks. Before accepting, two requests: 1, is there a way to avoid rasterizing in identiconCells - on my system the diagonals look ragged. 2 Can you explicitly parametrize identicon size?

comment Wordcloud creates a messy image
@Miguel, this seems to be a regression, as I now get messy clouds with the same code that made clean ones in 10.2 I think. Can you contact WRI tech support?

comment How to override DisplayForm of (mixed) time Quantity
Xavier, thank you for this info, this more involved than I thought it would be. Does every expression with a DisplayForm have its own _UnitBox?

comment What's a good back-end for a stateful client/server app that uses Mathematica for a front end?
Fyi, are you aware of emeraldcloudlab.com - this is a beta-stage cloud-based life sciences startup. In addition to the ECL-1 robotics plant, uses Amazon AWS for data & computation and Wolfram stack for its SLL = Symbolic Lab Language.

comment How can I exclude endpoints of intervals?
Couldn't the language use Except to support open endpoints, eg Interval[{0,Except[1]}] ==> [0,1). No problem with representation, what about interval computation?

comment Can Mathematica Handle Open Intervals? Interval complements?
@Szabolcs, Interval[{0,1}] ~ IntervalIntersection ~ Interval[{2,3}] ==> Interval[], empty interval.

comment The Orbit and Perigee of the Flamsteed comet
@J.M. this is nice. Given the computational tools available, could you complicate it by adding green lines at perigees labeled w/ times and distances?

comment Historical Exchange Rates via FinancialData
@RonaldMonson, it's great that trees of complexity b^d are being mastered, eg Chess: b=~35, d=~80, vs Go: b=~250, d=~150 ["Mastering the game of Go" Nature Jan 2016]. In real life games are not perfect information and who's to tell how big the trees are, and branch values.

@RonaldMonson, nevermind the game of Go - though that's interesting for AI. Compare Bloomberg's thousands of journalists, editors and engineers curating data and building queries that show up as facts and trends, not as predictions.

comment Probability of a random point inside the intersection of two triangles
Re "I'M POSTING AS I DERIVE:", that's cool, that's like Vangelis composing and recording in real time (see YouTube documentary).
