@William "as many functions as mathematica" is probably not the best yardstick to measure the effectiveness/utility of a language. At the current pace, Mathematica 10.5 will have more symbols in the global namespace than there are words in the Oxford English Dictionary.

You are right the number of functions is no way to judge a language. If anything the language with fewer functions should win of course. :D

@Karsten7. Finally ! new mma version knows about road, streets, ... according to the examples in TravelDirectionsData (in particular see td["ManeuverGrid"]). Cool ! It's gonna be war with Google Maps ;)

Hi

@William I am not sure what your reasons are for starring so many things but please bear in mind that it is not intended to be the same as voting. It is meant rather as a way to pin the post for the attention of other visitors to the chat. I previously unstarred one of your stars on my posts since I could not figure out the reason for it and thought it must have been a mistake.

I am using Mathematica to determine numerical value a double integral problem. I receive this warning message, therefore, the result is not correct. any suggestions:

NIntegrate::slwcon: Numerical integration converging too slowly; suspect one of the following: singularity, value of the integration is 0, highly oscillatory integrand, or WorkingPrecision too small. >>
 
Oleksandr R.
Oleksandr R.
@barznjy what WorkingPrecision are you using?
 
barznjy
barznjy
@OleksandrR. I am using the default machine precision
I haven't changed anything
 
Oleksandr R.
Oleksandr R.
@barznjy is it possible to increase it, per the suggestion of the message? I am assuming that the other suggestions NIntegrate gives do not apply to your integrand but you should certainly verify this
I need to go and catch a train. Bye...

@OleksandrR. NIntegrate::precw: The precision of the argument function (xxxxxxxx) is less than WorkingPrecision (24.`). >>

Q: Wolfram Tech Conference 2015

kaleAbout that time of the year. I'm going for the first time this year. Anybody else going, and would there be any interest in an SE-meetup?

Wolfram Blog: Using the Wolfram Language in the Classroom: Chemistry
posted on October 07, 2015 by Rob Morris

Welcome to day three of the Wolfram Language in the Classroom series. I hope you’ve enjoyed the lessons so far. Today I want to show you how data built into the Wolfram Language can be used in the chemistry classroom. The Wolfram Language has information on over 44000 chemicals and thus provides a perfect environment [...]

Sometimes, when I need something to cheer me up, I read this
And then, all of the sudden, it becomes clear at which pace bugs are going to be fixed in Mathematica :P
This makes my day.

@OleksandrR. Apologizes I have always viewed the stars as votes more or less. Will star more cautiously.

How does OptionValue[] know which function it is being called from? I.e. f[o : OptionsPattern[]] := OptionValue[foo]. Is there a way to get the function that is currently being evaluated? Return knows function call boundaries as well because it cannot return something to beyond a function call, i.e. f[]:=Return[1,g]; g[f[]] won't work.
I don't quite see how this would be possible with Stack.

Also I don't ever star something unless it has already been starred so I doubt I was the only person who you should be complaining to.

Q: How to best handle the same message attached to different functions?

SzabolcsThis is a question about how to best handle repetitive messages when writing packages. Usually there are lots of ways to do the same thing in Mathematica. And often more than one of those ways is not robust or has some problems which are not immediately obvious. Hence the question about best p...

I'm looking for robust solutions, suitable for production code.

A: Attaching the same message to several symbols

jkuczmMessages defined for a symbol are stored in list of rules Messages[sym] similar to DownValues, UpValues etc. We can use this fact to create general message inheritance mechanism. Let's start with defining custom message on our own general symbol: ClearAll[general] general::myMessage = "text of ...

I need some ideas for a good API for isomorphism functions with edge and vertex colourings. Without colours it must be like IsomorphicGraphQ. But some functions will have only a single argument like GraphAutomorphismGroup.
Optionally vertex colours or edge colours may be specified.
Any suggestions? How would you design your API?
