The OS gem allows for some easy telling if you're on windows or not.
```ruby
require 'os'
>> OS.windows?
=> true # or OS.doze?
>> OS.bits
=> 32
>> OS.java?
=> true # if you're running in jruby. Also OS.jruby?
>> OS.ruby_bin
=> "c:\ruby18\bin\ruby.exe" # or "/usr/local/bin/ruby" or what not
>> OS.posix?
=> false # true for linux, os x, cygwin
>> OS.mac? # or OS.osx? or OS.x?
=> false
>> OS.dev_null
=> "NUL" # or "/dev/null" depending on which platform
>> OS.rss_bytes
=> 12300033 # number of rss bytes this process is using currently. Basically "total in memory footprint" (doesn't include RAM used by the process that's in swap/page file)
>> puts OS.report
==> # a yaml report of helpful values

If there are any other features you'd like, let me know, I'll do what I can to add them :)

Related projects:
rubygems:
```ruby
Gem::Platform.local
Gem.ruby
```
The reason Gem::Platform.local felt wrong to me is that it treated cygwin as windows--which for most build environments, is wrong. Hence the creation of this gem.
the facets gem (has a class similar to rubygems, above)
```ruby
require 'facets/platform'
Platform.local
```
the ["platform" gem](http://rubydoc.info/github/ffi/ffi/master/FFI/Platform), itself (a different gem)
```ruby
FFI::Platform::OS
```
