Several recent posts have remarked that it would be useful to have a general form of BinLsts which could bin a list by means of a function applied to the first level, similar in principal to SortBy. After some thinking, it occurred to me that...
Today I loaded and evaluated a simple notebook I saved yesterday. When the evaluation got to a Histogram statement it stopped and displayed "Updating from Wolfram Research server" for about a minute. I'm running 10.3 on Windows 7 x64. I thought...
When I look at the dashboard right now (Monday 1509 PST) using Firefox and Win 7, I see the first 3 posts at 33, 36 and 40 minutes ago. The 4th post is at 6 hours, with more older posts following. Is it really the case that we went for over 5 hours...
I just installed 10.3. Here is the result of running the WordDefinition function exactly as it appears in the docs: In[3]:= WordDefinition["dolphin"] During evaluation of In[3]:= CreatePaclet::badppi: The paclet...

Mathematica has excellent functionality for the production of computer sound generation and signal analysis. Putting these together with a USB microphone seemed a good way to examine the frequency response of my home music system. The system is...
There are a lot of interesting sonification capabilities in Mathematica V10. They are generally organized into primitives which can be combined in Sound objects and then played, emitted, or exported. For example, it is easy to generate tones,...
