| In the game of 24s, players turn over four cards from a deck that has had the face cards removed, thus revealing four integers between 1 and 10. Using each number exactly once and no additional numbers, they race to make the number 24. In simple... |
| I've been playing around with `Predict[]` with multi-dimensional datasets and, for small training sets anyway, things seem to work correctly. For example, trainingset = { 47, "sex" -> "M", "height" -> 100, "weight" -> 60|>, 22,... |
| I routinely work with nested Associations that might be efficiently queried and manipulated with the Query[] command, but I have trouble making the command do what I want. A trivial example: The following dataset describes a couple of grades at a... |
| I often deal with graphs involving large dollar amounts over time. Mathematica will generally format Y-axis ticks as scientific numbers `{1.0x10^6, 1.2x10^6 . . . etc.}`. So for example, mydata = EventSeries@ ... |
| I executed a simple SQL query (MySQL if that matters) and rather than returning the response (known to be about 2 million items), I get the error JDBC::error: GC overhead limit exceeded How large a response is allowed? Is there any way to... |
| I export Mathematica tables to Excel every day, for sharing reports with non-Mathematica users. It exports the values without flaw, but ignores any formatting. Consider the following: colHeadings = {"datum 1", "datum 2"}; rowHeadings =... |
| I have written numerous WSTP applications that take data from Mathematica, manipulate it in combination with data retrieved from other sources, and then return it to Mathematica. See for example https://github.com/MichaelSternNYC All of these have... |
| I recently picked up an old project involving WSTP (formerly MathLink) programs, and as a starting place tried to get the demos provided by Wolfram to compile. The instructions were dated, referring to Visual Studio 2010 and 2012, and key sections... |
| I have been working with a simulation tool that generates large volumes of data, and it's time to start saving this to a proper database. Is there an established mechanism for saving TemporalData objects and/or Datasets into a SQL database, and for... |
