comment Light syntax parser for Mathematica?
@acl I've been giving sublime a try and it looks nice (it even has decent vim commands and modal editing support out of the box). Please post the fixed version so that I can give it a try. You can post here in your answer too, I suppose.

comment Dual-Grid Graph Paper With Mathematica?
@ZippyThePinhead I didn't read the article... just saw the figure. Do you want to orient the lines along some rotation θ instead? If so, then you'll have to use RotationTransform with primitives or as in J.M.'s answer.

comment How do I set the font for output in my stylesheet?
The earlier question did not concern output styles. The reason you can't do this easily is because Core.nb defines DefaultFormatType -> DefaultOutputFormatType for the output style and this is the StandardForm. You can set DefaultFormatType to some other *Form and change that instead, because modifying StandardForm will also change the input sytle.

@Szabolcs and raxa: you're probably looking for Internal`$EqualTolerance.

There's this for textmate on macs github.com/shadanan/mathematica-tmbundle... There might be some editors on ubuntu that can interpret textmate config files

comment Why to do parentheses change the results of a calculation?
In any case, floating point operations are not necessarily associative/distributive, even if the underlying mathematical operations are.

@alancalvitti It is left-associative, which is what the OP did here.

You probably want Abs@Sign@tmp3, which is the same as Unitize.

comment Is there a way to hide or toggle the visibility of code?
@chris Is there a way to hide it otherwise? I don't think you can fold a single cell.

@yulinlinyu Maybe the default view in yours is different. Try flipping the map upside down...
