looks like in order to do it you need to either turn on "universal access" then use either applescript or the access API's in C to do it, or use some internal coregraphics private api's (in C). So for java users, its either ffi or JNA or the like, or call out to an applescript script.

But didn't it also add background apps? That's what will really give the speedup, I think.

Benefits of Firefox

The benefits of firefox:

the adblock plus plugin [plus myriad other plugins]
Reasonably speedy, well supported.

Drawbacks:

It takes up more RAM than Chrome (i.e. slower for older machines), renders, for me, slightly slower than Safari/Chrome [in windows, at least].

how to compile ruby with increased garbage size

You may have noticed when you're running long-ish rails processes in windows that it sometimes pauses briefly, then continues on its merry way.

I have, at least.

The problem can be attributed to the garbage collector.

Ex: with one operation large_table.find(:all).each{||...}

I would receive something like 10 0.10 second pauses before it finished--increasing my overall time by at least 25%

Tweaking the malloc limit [the amount it will grow before doing a GC limit] changed that to something like 2 0.25 second pauses--which caused things to speedup considerably.

How:

install msysgit

c:> git://github.com/oneclick/rubyinstaller.git

cd rubyinstaller

set CCFLAGS=-DGC_MALLOC_LIMIT=60000000

rake # build ruby 1.8 in sandbox/ruby18_mingw

rake ruby19 # build ruby 1.9 in sandbox/ruby19_mingw

Installers hopefully coming soon.

Another option for speeding things up is building with GCC 4.4 instead of the 3.4.5 currently used.

Here's a download that does that for the adventurous:

http://all.faithpromotingstories.org/ruby_distros/ruby19_mingw_44.tgz

Anyway, watch this area as I'll post various ruby executables with different (faster) compiler options, and experimental like using tcmalloc, etc.

Thanks and good luck to all your windows+ruby users (like myself) out there!

Also much thanks to Luis and the one click group for making it possible to use these cool tools.
