I have tried more than once to use Time Series to pack and work with uniformly sampled signals, but it just feels clumsy

@belisarius Here is variant of your idea for this answer:

DynamicModule[{graph, pts, update}
, graph = RandomGraph[{10, 21}]
; pts = GraphEmbedding[graph]
; update[vc_, _] := graph = SetProperty[graph, VertexCoordinates -> (pts = vc)]
; { Column @ pts
  , LocatorPane[Dynamic[pts, update], Dynamic[graph]]
  }
]

Alas it is liable to fail under V10 as well :(

belisarius

@WReach Damn, they keep breaking everything :(

WReach

Yeah. Oops, I'm breaking stuff too... the Column should be dynamic.

belisarius

I hate the "it doesn't work anymore". And it happens way too often

WReach

@belisarius Yes, V10 has been very painful in this regard. It added so much, but took away a lot at the same time. I'm still on the fence about whether it has been a net gain. Here's hoping that 10.0.2 tips the scale the right way...

belisarius

@WReach Well, I decided to postpone migration. Hope I can do it in 10.0.2- I can't afford the time to test for bugs!

Or should I say -"for more bugs"-

@belisarius Yes... just when you think you've memorized where all of the landmines are buried, a new release comes out. ;D

Why it is so:

NumberForm[#, {5, 2}, ExponentStep -> Infinity] & /@ {.08, 1.08}
> { 0.00, 1.08}
? :(

@Kuba Can you try my ContinuedFraction oneliner from above? Is it just me, or is there something very odd going on there?

Kuba

@kirma I can reproduce your output but I can't parse it now :/

I'm not bright enough to do that on the fly :P

kirma

@Kuba It's ContinuedFraction behaving very oddly. Somehow I have hard time believing it really does that - it means that for large portion of "whole" limited-precision reals it does completely unexpected things.

Does anyone know what could cause Show[] to display only one of its graphics? I tried Show[Plot[6.28318/Sqrt[30/0.3 + 9.81/x], {x, 0.15, 0.35}],
ListPlot[{{0.15, 4.8}, {0.2, 5.1}, {0.25, 5.3}, {0.3, 5.5}, {0.35,
5.6}}]] and only the Plot is visible.

@JamalS add PlotRange -> All, Show takes options from first argument only.
