I cannot find any clearly description about the upgrad from ESXi 4.x to ESXi 5.0. ( I can just found documents about the upgrades of vSphere, but I do not need them.) Does anybody knows a good document about the ESXi update?
Just boot from the ESXi 5 installation CD, and make sure you pick the option to keep the existing datastores during installation (and make damn sure you have a good set of backups!)

I'm trying to learn Ruby On Rails, and found I can't really use Ruby 2.2.2 because Nokogiri doesn't support it on Windows yet.
How do I roll back Ruby to an older version so I can develop on an older framework while I wait for Nokogiri to come up with a product for Windows and Ruby 2.2.2?
What is the best way to uninstall it so I don't have bits hanging around that might cause issues?
This is in response to my question: "Error installing "nokogiri" in a Ruby on Rails application?"
Linux users: please remember that not everyone is interested in switching their OS, running 2 machines, trying to figure out dual boot, or dealing with virtual machines dragging down a host. While Linux is a great environment for software development, people, like the OP, just looking to try their hand at something (like ruby/rails) should not immediately be told to switch to something completely unfamiliar which might not even adequately support their normal day to day activities.
Since I am not a believer in making anyone leave an environment they are comfortable with (especially since you stated "learning". Why would you want to make an additional investment just to try something out?) and because I did not want my comment to get over looked as it will help with your issue, I have decided to post this as an "answer".
Mac and Other *nix based OS's have the ability to install rvm (Yes I know there are more but rvm is my personal choice and a community favorite) which allows you to manage different versions of ruby on the same OS.
While rvm is not available for Windows there is a small application called uru which will get you as close from a windows standpoint.
Installing a version manager means that you do not need to uninstall or rollback anything you can simply install a new/old ruby version side by side the current versions you have and switch between them fairly easily from command line.
While uru does not have all the fancy features that other applications like rvm possess (by design). It contains the important ones (primarily in your case switching ruby versions). The CLI is very simple and straight forward. Examples of uru Usage
Also: Please note I work in an Windows centric Office and have developed more than a few fully functional rails applications on a windows machine. Yes there are some headaches when dealing with native extensions and know that you will always be slightly behind the leading edge for ruby and rails but it is completely possible and feasible to build enterprise level web applications completely in a Windows environment without ever installing Linux at all. (Note I do use dedicated Linux machines for non development web servers)
Go to your control panel and find the ruby or rails installer. Uninstall it. Go to your file explorer and make sure the folder is gone.
Now go to http://rubyinstaller.org/downloads/ and pick an older version. Follow that process just like the first time you installed ruby. Then go get nokogiri and whatever other gems you like and enjoy.
I had the exact same issue when trying to some gems(stanford core nlp & treat) to work that relied on JVM that was 32bit instead of 64 like the version of ruby I was running so I reverted to 1.9.3.
I'm also in the avoiding moving to OSX or linux camp so I feel your pain man.
Let me know if this works and good luck!
Is there a place (website) where i can find information on which VM is needed (minimum/maximum) for a specific Pharo or Squeak release on a specific OS?
I don't know if that exact information is documented, but I can try to give you a brief explanation... Even Pharo and Squeak paths have diverged a lot in the last times.
Pharo Official VM is the CogVM which is a StackVM with JIT. Then it also have StackVMs for platforms where code generation is not allowed.
The official virtual machines for Pharo are listed in http://www.pharo-project.org/pharo-download, and they work for sure from Pharo 1.2 up to Pharo 2.0. You can also have a look at the complete set of built vms in the CI server https://ci.lille.inria.fr/pharo/view/Cog/.
For older releases, Pharo (1.0 and 1.1) keeps a history of one-click distribution where the vm is freezed along with the image. You can find them in here: https://gforge.inria.fr/frs/?group_id=1299
On the other side, for Squeak, the same CogVMs should work in their latest versions, otherwise you should get an interpreter VM from http://squeakvm.org/index.html.
Hope it helps a bit
As #guillepolito says, the best thing today is to take the ones from the Pharo continuous integration Jenkins server (or pick a one-click).
Squeak VMs have been fading out in my practice. I keep a number of them around but as I do use Pharo, I try to build my own version from the Jenkins source as there is a lot to be learned from using those.
It is not difficult to get them built on the main platforms and at least you know what's under.
The main problem is that Eliot Miranda keeps on doing his things in his corner instead of working on a shared source three. That's the problem of having a low truck number on that.
Is it possible to compile my Objective-C iOS-specific project on anything other than OSX? I spend a lot of time in Windows and it'd be less of a hassle if I could, at the very least, SSH into my Ubuntu machine and edit code / compile on there. I think the only thing I'd need the Macbook for would be editing storyboards and running the iphone emulator.
I just have a lot of free time every day, but don't have access to my Macbook until I get home around 7pm. Are there any good ways to remotely work on an XCode iOS project?
Yes, it is, although you'll need a jailbroken device for this. You are also going to need to build the opensource, non-official toolchain for yourself, or get a precompiled version.
Hey, you can even make GCC run on your iPhone itself (that's how I use it).
Why not SSH into the Mac and use the command-line tools that come with Xcode?
Or, more comfortably, just remote into the Mac via one of the many remote desktop solutions out there (TeamViewer is free for personal use and quite good at poking through NATs etc., but there are a lot of other options) and use Xcode.
I'm running Mac OS X v 10.4.11 and I want to install Xcode to compile and run ruby on rails. When I go to apple site I must download latest version of Xcode which does not run on my version of OS X. Where can I download a version of XCode that i can install in my environment. Can anyone provide me with a link?
You have to register on their developer site.

[New Link as of 01/21/2012:]

so enjoy :)
For those that may want to download Xcode for MacOS X 10.4 (Tiger), you may opt for a "side-channel" solution of downloading the disk image from other sites (e.g., like via torrent sites), since it is quite likely that Apple breaks any of the URLs given above at any point in time and/or puts it so buried down their site that it is virtually "unfindable".
In this case, the following data may become handy to ease the pain of future searchers:

MD5 sum: 3bd6c24d8fbbdf9007e15861d173764d
As I am trying to breathe new life to an iBook G3 with Tiger (that works perfectly fine, also with Debian installed), I will use a version of Homebrew called Tigerbrew, which, of course, depends on Xcode being installed.
XCode is distributed with MacOs, somewhere in additional tools folder or something like that on installer dvd.
Xcode 2.5 is the newest version for mac OSX 10.4 (Tiger)
Here's the new link (tested today), the old one is broken:

If you don't have installation disks, I can upload from mine, but not until tomorow :(. Meanwhile, i recommend You to try NetBeans (whether Ruby, or full version) http://www.netbeans.org/downloads/index.html. I was developing ruby on rails application for my company a year ago, and NetBeans proved to be the best solution for me.
That url works as for 10-2010: http://adcdownload.apple.com/Developer_Tools/xcode_2.5_developer_tools/xcode25_8m2558_developerdvd.dmg
I'm in the process of deploying a rails application to Windows machines. I do all of my development with OS X and Linux, but the final app will actually run on Windows machines.
That said, my client is looking for an all-in-one Apache(I had to talk him out of IIS)+Rails+Application deployment/installer. He wants to hand all of his (Windows-based) clients an install CD for their respective servers (they all want their own setup).
Is there anything like this in existence? I realize Capistrano exists but that requires a great deal of setup on the hosts (especially for Windows) beforehand and it's not very feasible in this particular case.
In the past I've used InnoSetup (http://www.jrsoftware.org/isinfo.php) for creating installers, but I'm not sure that's going to work in this case.
If you guys have any input, suggestions, or highly persuasive client techniques (to talk them all out of Windows =P) it would be most appreciated.
Best.
Try with RubyStack:
BitNami RubyStack is an installer that greatly simplifies the installation of Ruby on Rails and its runtime dependencies. It includes ready-to-run versions of Ruby, Rails, MySQL and Subversion as well as a number of third-party libraries like FiveRuns TuneUp. RubyStack is distributed for free under the Apache 2.0 license and has been packaged using BitRock's multiplatform installer.
http://bitnami.org/stack/rubystack
I'd look into using jruby with glassfish. Make sure the users have java and it should be good to go.
RubyStack is the closest thing to what you're after, although you might need to tailer the install a bit and remove some unwanted baggage. I don't know of any other Windows projects for a production environment (InstantRails is designed for development).
Maybe you can make InstantRails meet your needs.
Ruby and thus Ruby on Rails is a fairly notorious deployment on Windows even in the best of circumstances, moreso when the setup is out or your hands like that. I don't mean to admonish, but this definitely speaks to matching development and deployment enviroment (I once ran into similar problems when I found out that the Java enviroment we were deploying to was a good half-a-decade out of date).
As I don't have enough Ruby-on-Windows experience to fairly weigh in on the matter, I'd say either LiveCD's or CygWin deployments may be worth looking at (Always good to broaden people's view on alternate Operating Systems, right?).
Have you considered building a single version that runs in a VM?
For this particular problem, I'd go with a traditional Windows installer package like NSIS.
When I had a client with a Windows-only IT department, though, I found they were much more amenable to an XServer than a linux server. I don't generally think of OS X as a server OS, but it actually worked really well. I tried for linux first, and when they shot it down, I suggested OS X and they jumped at it.
It helped, I think, that they already supported some Mac laptops.
Good luck!
As other posters have suggested, RubyStack should be a good option. It is free and you can always use it to run your own 'post install' scripts to customize it for what you want. If you want a supported stack or addition/modifications to RubyStack you can get commercial support from BitRock We have done so for several Rails based companies that wanted a local version, including for the guys over at GitHub
