Due to some gems not working for windows im considering either  
installing cygwin or even going as far as installing linux (linux isnt  
the evil here, its the partioning and a whole sunday spent figuring out  
stuff).

Id rather go with cygwin but ive read posts that mention problems when  
you have cywin ruby and a windows ruby on the same system something  
about ---ubygems or something.

I know nothing about cygwin and its pros/cons nor how it will affect my  
current ruby projects and rails setup.

Do i need to install a cygwin verion of ruby? Can it coexist with my  
current version on windows. I dont want to have to uninstall it because  
ive just spent 3 days figuring out hwo to get get mysql working with  
rails 2.+ that requried multiple reinstalls. Id liek to leave it as it  
is.

any tips pointers etc greatly will really help out

Disclaimer: I am not using any database bindings at the moment. I'm  
pretty happy using the cygwin version only. Currently you need to  
compile from source if you want to have 1.9.1 but that's not a big  
issue on cygwin (the usual configure, make, make install loop). I  
would guess that you do not have to delete the Windows version but I  
believe you better keep them apart. That would mean installing gems  
twice if you want to have them in both environments.

Personally I haven't felt the need to use another Windows version but  
I'm not doing GUI either.

Just my 0.01 EUR...

Kind regards

robert

I'd suggest using virtualization (VMWare, etc.) to install a Linux distro.  
Much simpler than setting up dual-boot, and much more versatile than  
cygwin (you can snapshot and revert VMs, clone them, etc.)

From rubygems list, it looks like one-click is almost finished

Just in case, if someone want to test the binary builds of new  
One-Click Installer, you can try downloading those form there:

[http://rubyinstaller.org/downloads/](http://rubyinstaller.org/downloads/)

Those are direct builds from rubyinstaller repository and includes a  
fresh sandbox with MinGW+MSYS to help you 'fake' a complete \*nix  
environment.

If you have a Windows VM (or real PC) please try those out, since new  
One-Click Installer will be built on top of that.

ahh that sounds good. Unfortunately i just realised I wont be able to  
use my beloved e-editor via linux.... perhaps cygwin is the way to go.  
But ill definately look into it as a way to try out linux.

(is there a text-mate / e-editor style editor for linux?)

Usually virtualization (VMWare, etc.) is too slow to use. I would  
recommend dual boot.

If it's a not a Mac then friendly Linux distros (Ubuntu, Debain,  
CentOS, Fedora,...) will install the dual boot very smoothly. The  
hardest part is making the decision on what part of the hard drive to  
allocate to Linux.

ahh robert, missed your reply there. Initially Id like to keep the  
windows version in reserve just in case i dont take to well to cygwin.  
If cygwin goes well then id be willing to just delete the windows  
version and keep only the cygwin one.

I don't use either of those [1] but there are any number of possible  
alternatives: shared folders for the two "systems", edit on Windows  
and `cap deploy` to Linux, etc.

[1] I mostly use jEdit, which is cross-platform and extremely easy to  
customize through shortcuts, macros, and plugins.

That's a uselessly broad statement. I've used VMWare on Windows,  
Linux, and Mac hosts, and never found that to be true, even running  
multiple VMs simultaneously.

Maybe slow on a netbook or an iPhone or something. 🙂

But certainly the OP can try a virtualization approach first and see if  
it's performant enough on his hardware for his needs.

TMTOWTDI.

e-text was just released "shared source" with a "build your own" linux  
port available (check their blog).  
I'd recommend virtualbox works like a champ for me--using it right now  
Linux guest on XP host.

the andLinux project is very surprising, it allows you to run windows and

Hassan,

My experience was with VirtualBox on Windows on a new IBM Touchpad  
laptop about a year ago. The environment was snappy at the very  
beginning, but became slow (compared to native Linux installations)  
when I used Ubuntu's package manager to install software.

Sorry for not being specific.

This is getting slightly off topic but does somebody know how this  
compares, performance-wise, to virtualbox? I'm wondering if it is  
worth the hassle to try andlinux just so that the virtual windows show  
up in windows.

I'd imagine andlinux is faster [1], not sure how much.  
virtualbox does have "seemless" mode which is nice, but it shows all  
virtualbox windows, not just the topmost, when you use it, so it's  
sometimes annoying.

Twould appear that they're all close to the same speed  
windows mingw:  
$ time ruby -ve '10000000.times {33}'  
ruby 1.8.6 (2009-03-31 patchlevel 368) [i386-mingw32]

real 0m1.235s  
user 0m0.015s  
sys 0m0.030s

rogerdpack@andLinux:$ time ~/installs/ruby-187-p160/bin/ruby -e  
'10000000.times {33}'

real 0m1.490s  
user 0m1.460s  
sys 0m0.030s

ubuntu as a guest VM:  
rdp@rdp-vm:~/$ time ~/installs/ruby\_187\_p160/bin/ruby -e '10000000.times  
{33}'

real 0m1.251s  
user 0m1.160s  
sys 0m0.024s

I have had a few troubles with andLinux not working perfectly. It does  
integrate nicely, window wise, though.

Thanks all for your suggestions.

I tried cygwin it seemed ok but then i explored using virtualbox and how  
easy it is to get linux running within windows without having to  
partition or worry about losing your drive. Theres a great recent  
tutorial on how to get up and running at

The good thing about using virtual linux is i can use my windows  
e-editor to edit my files whilst at the same time having linux be the  
host for rails which means less hassles with gems etc.

If i take to linux and find a linux based replacement for e-editor Ill  
do a fully fledged install but for now its excellent! better than i  
imagined. Id heartedly reccommend any other windows based users who are  
either fed up with having to deal with gems not supported for windows or  
who were contemplating trying out linux but feared the installation  
process to check virtual ware out!

thanks again all for your input.  
re: addlinux i couldnt find much on using it with rails and as im a newb  
to linux i thought its go the more popular route - more blogs with how  
tos etc

Thanks for your feedback! One question out of curiosity: why did you  
pick VirtualBox over VMWare Server (free as well)? Was it just  
because of the ease of installation?

Kind regards

Hi Robert,

Yes just the ease. I did look into performance comparissons briefly but  
for a light user like me it didnt really matter. The ease was more  
important plus the the lifehacker post on setting up was the most recent  
guide i found via google.

over at [hardocp.com](http://hardocp.com) a lot of people were saying they were happy they  
switched but i cant remember exactly why.
