garnered from a few entries:
download 'nice.exe' for windows:
http://members.ozemail.com.au/~markhurd/SomeProgs.html
then
require 'win32ole'
loop {
procs = WIN32OLE.connect("winmgmts:\\\\.")
procs.InstancesOf("win32_process").each do |p|
if p.name =~ /ruby/
command = ".\\nice -i -p #{p.processid}" # i for idle
print "running #{command}\n"
system(command)
end
end
sleep 1
}
in that directory will always force your ruby's to idle.
sorry it's not all ruby :)

meant "you need to go into dbconsole and force it to 'exec' the full path name of mysql.exe, not just 'mysql.exe'"
also if it says
Couldn't find database client: mysql. Check your $PATH and try again.
but mysql IS in your path, no fear, edit dbconsole.rb and add mingw wherever it does =~ /win32/

hp t43 is very soft quiet
So...break open your new ibm T43 and the volume is very low? there's little buttons at the top that [annoyingly] might be making it so. Try it!
binary executables from gems don't show up in the path with ubuntu
nope--they don't for some reason. No idea where ubuntu's default "apt-get install rubygems1.8" installs it binaries, but it's not in the path.
Fix:
install rubygems from source, then it will install the binaries in the right spot after that.

rubyforge broken with windows
yep--use linux [install a virtualbox, etc. ugh] for this to work, it appears...at least in a friendly way...
virtualbox woe
click install guest additions does nothing
might mean "unmount your currently mounted cdrom first!

best ruby garbage collector

Has what i would consider the 'best' for its current incantation--which is mark and sweep everything every time. I would recommend against going for it and instead recommend for a generational one.
