But please don't email me with requests about Q&A. Post them in the site instead.

Infix should be used only where it is essential... like in "feliz año nuevo" @rm-rf

DistanceTransform[] has a few glitches, but it basically does what you want. What else do you want?

comment Solving an identity
Well,not much, really. bMax tends to a as a increases, so the gain is worth only when a is relatively small ;(

comment Solving an identity
You can get slightly better bounds for your iteration by looking at the results of Reduce[3 Sqrt[5*37^(1/3) - 16] == a^(1/3) - b^(1/3) - c && a > 0 && b > 0 && c > 0, {a, b, c}, Integers]

@rm-rf Isn't this equivalent? toHrMin = DateString[N@#, {"Hour", ":", "Minute"}] &;

@Kuba The ping thing works only if you already participated in the conversation. I knew you weren't going to be notified, but it wasn't important enough to try to get your attention. I just wanted to set the attribution for the idea

comment Clustering a set of points
This is a very nice one. BTW, the native BreathFirstScan[] in its current incarnation seems to lack control flow, so once it's started, it'll always visit every connected node of the graph, but there are some good alternatives already posted in this site.

comment {Latitude, Longitude} to Transverse Mercator projection
Ok, it was just a try :(. Anyway, I fail to see what kind of 2D projection could give coordinates in that range (I don't know anything about Georeference!)

Is this the simpler example of your problem you could find?

Try GeoPositionXYZ[GeoPosition[{41.8713, -87.6737}], "NAD83CORS96"]

Could you please specify what would be the correct result in your example?

comment Why does $Failed have attribute HoldAll?
@LeonidShifrin Ok,just bookmark it for later if nothing better comes in. We should keep out unanswered pyre low :)

comment Why does $Failed have attribute HoldAll?
@LeonidShifrin I think you should post that as an answer. I doubt we can get a more insightful one.

At least it deserves to be kept as a comment. Not that I recommend it though:)

comment Change ticks from number to hours
@Kuba posted something like this in a comment and then deleted it: ListLinePlot[Quantity[list, "Seconds"], TargetUnits -> "Hours"]

comment Change ticks from number to hours
ListPlot[list, PlotRange -> {0, 24 60 60}, Ticks -> {Automatic, Array[{3600 #, #} &, 24]}]?

@Pam Try MapIndexed[f, {a,b}] to see that #2[[1]] takes values 1, 2 and #1 takes values a, b
