Software developer at yWorks GmbH.

Usually I'll answer questions here about Java, C#, PowerShell, batch files, random numbers, regular expressions and Unicode. At work I primarily deal with C++, C#, PHP and a few other things.

My interests are mostly HCI, Interaction Design and UX. Recently I18n joined that list as well. That does not mean I have profound knowledge in either of those fields, just that I am interested in them.

Note: People contacting me outside SO/SE is fine, but for discussing their own questions or answers SO already provides a mechanism, namely edits and comments. So please use those things first.
I do hang around on Freenode as Hypftier, though.

comment I have learned that 1/0 is infinity, why isn't it minus infinity?
alpha123, in many programming languages (most notable those descending syntax- or semantic-wise from C) 1/0 is interpreted as an integer division where this is indeed an error. If you force floating-point numbers you get the same result you attribute only to Javascript. E.g. 1/0.0 will usually yield positive infinity in those languages.

alpha123: That's normal for any system using IEEE 754 floating-point arithmetic, i.e. nearly everywhere that isn't a CAS. Javascript isn't alone in that regard and floating-point arithmetic is a mere approximation of math and thus adheres to other rules (you complain about $x+1=x$ for large $x$, too?)
