comment InfiniteLine Woes
@MarcoB, That's just what tripped me up. And I was in an unusual hurry too.

comment InfiniteLine Woes
Thanks. The syntax even matches that of Line. I'm surprised I didn't try it.

What about this? (from the documentation) Graphics[InfiniteLine[{0, 0}, {1, 1}], Frame -> True]

comment Reconstruction of interrupted paths in images
ImageCorners reference.wolfram.com/language/ref/ImageCorners.html may be useful for step 1.

comment Pull out scaling factor from a denominator
Algohi, That seems to be a general solution to the problem.

Algohi, try ((2 + x)/7)[[2]]

comment VertexLabels, EdgeLabels and the direction of the arrows on a directed graph
You should be able to find solutions to all of your problems by consulting the documentation. See GraphicsGrid,VertexCoordinates, EdgeStyle, etc...

comment Font presentation difference between version 9 and version 10
Looks fine on my MacBook with Mathematica v. 10.0.2 The font is heavier than your upper image, but far smoother than your lower image. Shouldn't Georgia be a serif font? Your lower image is sans serif.

comment Dynamically Update both a HorizontalGauge range and the value
This seems to offer more general solution (which is great because I want to add additional scales), but the lower marker sometimes jambs, sitting immobile while the upper marker is being dragged.

comment Fine precision control in IntervalSlider
Basically, I want students to be able to explore a number line by zooming in or out at will. I plan to have multiple Horizontal Gauges on display at once. But I am still thinking about the functionality, the operations I want students to be able to apply.

comment Fine precision control in IntervalSlider
Good point. I hadn't tried adjusting the interval size!

comment What is Association[Rule[“ID”,number ] and how it is used
I'm puzzled. Look at TreeForm[ds1] and then ds1[[1]]. How can you get the full list of data out of the dataset?

I wasn't aware of that limitation. Thanks.

comment How can I stop Mathematica from re-arranging formulae in TraditionalForm?
reference.wolfram.com/language/tutorial/… and reference.wolfram.com/language/guide/… may be helpful.

comment Automatically convert pairs of directed edges to an undirected edge?
Mr.Wizard You are indeed perceptive. Yes, I was.

comment Automatically convert pairs of directed edges to an undirected edge?
+1 for using Union instead of Sort and Union

comment Automatically convert pairs of directed edges to an undirected edge?
Would you clarify how /. {{_[a_, b_], __} :> a <-> b, {x_} :> x} works? I don't fully understand _[a_, b_] but it seems to be an opaque variation of belisarius' Rule[a_,b_].

One possible title: "How do I simulate raw data (with measurement error) from a known function?"

comment Using GraphData to generate all directed graphs with n vertices
A generalization of your method for labeling: graphs[n_] := Module[{c, cb}, c = GraphData["Connected", n]; cb = GraphData[#, "EdgeRules"] & /@ c; Row[Column[GraphData[#, {"StandardName", "Image"}]] & /@ c, Spacer[10]]]

comment Using GraphData to generate all directed graphs with n vertices
+1 Nice use of graph names, "Connected", and isomorphism.
