comment Spacing a set of points
Could you please edit this question to define "space out"? I suspect a graphic would not be inappropriate.

comment ArcSDE Compress Issue
When you edit, be sure to specify exact versions of Oracle and ArcGIS software in use. It also wouldn't hurt to review the basics of versioned geodatabase editing procedure, so your description can detail where you varied from the usual workflow. It sounds like you edited, then removed edits, and somehow want the edits back.

I'm voting to close this question as off-topic because geography trivia does not pertain to geographic information systems.

This question, or at least one similar, has already been answered previously. Search on your title to locate it.

comment Tool to create triangle buffer using Python in ArcGIS Desktop?
I'd hardly call that a "buffer." All you need is a little computational trigonometry for generating points at a fixed distance at 90, 210,and 330 degrees, then connect them.

You need to provide more information on the source of these files, and a guess as to the possible units.

comment Buffer ring problem with uses of make feature layer
This is a Python coding issue, a different problem at a different location. You should post the changed code as a different question. It would help if you add some diagnostic print lines, and include the output in your question (you might even be able to solve it yourself)

comment Determining epsilon for county polyline simplification via Ramer–Douglas–Peucker
It's unlikely that the ideal epsilon has any correlation to area, though you might try incrementally changing epsilon until there is a significant change in area. Whatever you do would likely be best done on an individual polygon basis (lest you collapse tiny polygons using tolerances for large ones).

comment Tools to export shps from Oracle database
You only get 2Gb (2^31-1) in either .dbf or .shp before the write is going to crash, so the sum of the widths of the fields and the number of average vertices are going to be your limiting factors (on a per row basis). You'd have to edit the question to include a DESCRIBE on the table(s) with row count and feature vertex density before this can really be answered.

comment Tools to export shps from Oracle database
How large are the source tables? The .dbf and .shp file size limitations will limit any shapefile export at some point (and the restriction is to the first failure - .shp or .dbf).

comment Determining epsilon for county polyline simplification via Ramer–Douglas–Peucker
I think you'll find that the optimal epsilon is similar between shapes of a certain size/complexity, but that neighbors are rarely of common size/complexity. You'll also introduce gaps between polygons of differing complexity with this technique (though if you don't zoom in, you won't see that).

comment How many interior and exterior rings can a polygon have in a standard ArcGIS shapefile?
@yo_haha I read that to say a polygon has one exterior ring, and treats multi-part polygons as a list/array of polygons. The shapefile specification does not distinguish between single- and multi-part lines or polygons (only multi-part points, which are stored differently than points).

comment Buffer ring problem with uses of make feature layer
No, the shapefile specification does actually require "8.3" naming (Naming Conventions, pg 2) -- it's just not enforced as it ought to be.

comment Buffer ring problem with uses of make feature layer
Spaces are forbidden in file names by the shapefile specification (and bad practice in general). What happens if you use underscores?
