I have a series of cities that I need to programmaticly draw arcs between on a global map. The arcs also have to be labeled with a series of values. Output needs to be png or something similar (i.e. I am not looking for a javascript solution.)
Any suggestions on ways of doing this? I can choose language or tool (so long as it is free).
From your description, any language would do. Java, Python, C# etc. They each have graphics libraries that make it easy to draw lines and text and output images.
Ah, found one that will work perfectly myself.

Processing might fit your bill

right now I have a big project with legacy C/C++ source codes. There are many global variables spread in different functions. In order to analyze the code, I need a tool which can take a look into these functions, check what local/global variables are used and modified in this function, and then better show theses interfaces graphically.
Does anyone have experience with this kind of analysis and know accordingly the tool names? I've tried Understand from SciTools, but it cannot deliver this kind of report.
Thanks!

I would like to generate random tone sequences in R (likewise https://en.wikipedia.org/wiki/Twelve-tone_technique) for creating rule-based items. I'm interested, if someone could suggest R packages, which could sonify data for making melodies based on number sequences (for pitch and duration of a tone).
Here is a package to analyze music, that might help.
Here is an example you can try out.
Replicating something similar like the answer to this questions is maybe rather what you want. There the OP requests code to play the happy-birthday song in R. They code in the answer has, notes, pitch and duration, that you can easily define by yourself and sample randomly from to generate a song.
I think that it might be simpler to do most of these things in python.
Hope this helps!

Are there any components built with polymer that allow displaying of tabular data? I would like something that compares with current UI grids out there.
I am interested in infinite scrolling and 2 way binding to json data in particular.
One good place to look for such things is the Component Kitchen
Looking there I found aha-table. It doesn't appear to have infinite-scrolling, but it lists pagination as a feature.
Not a completely useful answer but here's what I'm aware of:
Seems that the team plans to add what you're looking for - https://github.com/Polymer/core-list/issues/20
This might help you do something now - https://github.com/polymer/core-layout-grid

Does anyone know a tool/app to make a citation graph, or some app that can make a graph with papers and their references, and bibliography of papers?
I was told, that ieee has one, but i didn't fid it.
You could build this with D3.js using something like a force-directed graph.
Adding the fisheye distortion makes for great visual effects (not necessarily useful, but cute).
If the citation graph is not connex, using Colony is a great option.
As a sidenote, when looking for a visualization tool, I usually check the D3.js Gallery. It's amazing.

I need a Qt widget that will allow me to display a map.
It needs to be able to:
Run without a network connection to a map or tile server. A simple bitmap would be fine.
Place widgets, lines and graphics on the map, given latitude and longitude.
Calculate distances between points.
Compile on Linux and Windows.
What would you suggest?
Thanks,
sqqqrly
I'd recommend taking a looking at Marble.
It's included with KDE-edu, but if I recall correctly, the Marble library does not have any dependencies beyond just Qt, it's also under the LGPL, and it's cross-platform. You should be able to place widgets and various other things on the surface.
Quantum GIS is the leader of the pack.
There is a map editor written for OpenStreetMap, which uses Qt.
http://www.merkaartor.org/
For map rendering they uses Webkit, I guess, but not really sure. Try to contact the author or read the source.
Hi every one QMapControl and ArcGIS could be a good try.
