How Many Keystrokes Programers Type a Day?

most programing languages are garbage, when compared to Wolfram Language (aka Mathematica)

on power, practical useness, flexibility, and simplicity. Counting fancy ones like Haskell.

this is Mathematica: http://blog.wolfram.com/2012/07/20/on-the-importance-of-being-edgy-electrostatic-and-magnetostatic-problems-with-sharp-edges/

and, look at the use of math symbols.

Syntax Coloring in Editors

i can't decide which is the worst hack.

AutoHotkey Syntax Problems

or, unix perl sht. Example: Unix Pipe as Functional Language

or Second Life, the Worst Hack in Universe

or web dev with JavaScript html css dom. Example: JavaScript: Array vs NodeList vs HTMLCollection

in comparison, i think my complaints about perl, python, are penuts.

of the above, i think the winner is either Second Life or JavaScript web dev. Second Life probably worse.

Scala, Lift Web Framework

Lift (web framework)

Lift is a free web application framework that is designed for the Scala programming language. It was originally created by David Pollak who was dissatisfied with certain aspects of the Ruby on Rails framework.[4] Lift was launched as an open source project on February 26, 2007 under the Apache 2.0 license. A commercially popular web platform often cited as being developed using Lift is Foursquare.[5]
