I have been musing a lot lately, regarding what would be the perfect operating system (IMO), or as close as it could get. Here it is, in a not-so orderly manner, various characteristics, that I would desire, in my “perfect” operating system.
Kernel
The kernel would be a microkernel, with everything from the drivers, to [...]
Creating a Ruby 1.9 sandbox
1. mkdir /home/user/ruby19 (example folder)
2. cd /home/user/ruby19
3. mkdir src
4. cd src
5. wget http://ftp.ruby-lang.org/pub/ruby/1.9/ruby-1.9.0-1.tar.bz2
6. tar -jxvf ruby-1.9.0-1.tar.bz2
7. cd ruby-1.9.0-1
8. ./configure –prefix=/home/user/ruby19
9. make
10. make install
Now you can switch to this sandbox at any time by executing ‘export PATH=/home/user/ruby19/bin:$PATH’ in a shell.
Chipmunk Installation

So what exactly is the difference between a class and a struct in C++? After wondering and debating internally for quite a long time, I looked around the net and found the (simple) explanation that:
"The only difference between a struct and a class is in the default access."
That is, a sruct is public by default [...]
How easy would it be to build include graphs in ruby?
Here's my first attempt:
PLAIN TEXT
RUBY:
$list_of_files = Hash.new
$list_of_files.each {|node|
node = Array.new
}
def store_includes(pathname)
lines = IO.readlines(pathname)
lines.each {|line|
if line.include? "#include"
include_file = line[line.index("#include")+"#include".size,line.size]
fidx = 0
sidx = 0
if include_file.include?("\"")
fidx = include_file.index("\"") + 1
sidx = include_file.index("\"",fidx+1) - 1
end
if include_file.include?('<')
fidx = include_file.index('<') + 1
sidx = include_file.index('>') - 1
end
include_file = include_file[fidx..sidx]
$list_of_files[pathname].add(include_file)
end
}
end
def iterate_files(pathname)
list = [] [...]
Is there a more efficient way to extract the file extensions in ruby? I currently do the following.
PLAIN TEXT
RUBY:
ext = File.basename(filepath).reverse.split('.')[0].reverse
