comment Control which frontend session/kernel the Workbench gets attached to
@magma : thanks for following up. I find that I sometimes (I do some "tricks") and "attach" to the second MMA session from the Workbench, when the first is crunching some numbers. If it becomes reproducible, I will put them here

@magma Thanks. Those options are for specifying the MMA location - not to specify which instance to attach to

comment Speeding up inversion of symbolic matrices by invoking caching
@DanielLichtblau thanks for pointing out that Simplify benefits from caching (and not Inverse) - something new. I was thinking something along the lines of DumpsterDoofus's answer, which executes faster than the Inverse (I think I need to re-time it removing the Simpllify around the Inverse)

comment Speeding up inversion of symbolic matrices by invoking caching
Sorry. My question was, is there any predicatable takeaway from the caching - i.e. something that I can count on (in terms of time-saving)? Is there anything I can do as a user to speedup further operations. The doubt here is since I am not aware of how the exactly caching helps - does it extend to only the EXACT SAME matrix (wherein memoization would solve it) OR does the caching speedup inversions of the SAME ORDER (i.e. for ANY other matrix of 12x12) OR would it speedup ANY ORDER less than the current order OR anything else ?

comment Problem inserting data into a mysql table with column names having a space
Again problematic. I tried to create the table manually ,outside Mathematica, since I got some error when I was trying to set the default value of the string to be ''. But even after that addressing columns with a space in the name throws error. @Hans - how do I find what mode the JDBC is mimicking. I am wondering if its a problem with MMA and the Uniserver (I am able to access these columns from PhP on the same machine though)

comment Difference between AbsoluteTiming and Timing
@J.M. - something interesting - i noticed Timing[100000!;] is shown with "Second" in the output, whereas I dont see that on my machine's output

comment Problem inserting data into a mysql table with column names having a space
"\"Col 1\"" works for creating column - but is problematic while inserting using SQLInsert. Tried [Col 1] - it does not help either

Thanks you were right. On removing the assumption L>0 from the Simplify[] and the results match!
