What happens when a new value for an existing column is added? Will the older value be overwritten by the new value? Or the older value will also retain and can be retrieved (similar to simpleDB)?

Hi all,
I rather cleverly (or not in hindsight) installed RVM, which kept hanging whilst compiling Rubies.
I have removed the .rvm directory but now my system has reverted to Ruby 1.8.7 i.e. when I type:
ruby -v
which ruby
they both point to 1.8.7.
How do I get the ruby command to point to my 1.9.1 installation, which is located in /usr/local/lib/ruby/1.9.1? I'm on OSX 10.6.
Thanks

Hello,
I my software I need the client to install a database server (MySQL in my case). I'm deploying the setup and making user install it like a pre-requisite.
After installing the DBMS server. I need to setup databases (that I created) on the client machine. How to do this automatically (as part of installation.)?
I was hoping it was as easy as referencing my existing libraries to use them with WP7.
However, it complains about not able to load them because of .Net CF when I actually use them.
Do i need to recompile them to .NET CF or something?
At the moment I have an existing application which basically consists of a desktop GUI and a TCP server. The client connects to the server, and the server notifies the client if something interesting happens.
Now I'm supposed to replace the desktop GUI by a web GUI, and I'm wondering if I have to rewrite the server to send http packets instead of tcp packets or if I can somehow use some sort of proxy to grab the tcp packets and forward them to the web client?
Do I need some sort of comet server?
I have some kind of "data engine" between multiple "data consumer" processes and multiple "data storage" sources. I'd like to provide Linq capabilities to the "data consumer" and forward the query to the "data storage". The forwarded query should be some structured query (like, let's say, NHibernate Criteria).
Is there any existing structured query library that could allow me to "just" translate a Linq Expression to such a structured query?
Is it possible using php's XMLWriter to insert a new node to an existing xml file, and then save the file. This would be much more benficial to me that actually creating a enw file every time i want to update an xml file.

Where m.Name.IndexOf(query) > 0
With plain old sdl in C i would copy the dlls i need into the exe directory and was able to run without install.
Now i am using sdl.net. I tried doing that but had no luck. Not even a clue to what dlls are missing as i did in the old C way. How can i have users run my sdl app without installation?
We have an existing PHP page (from an earlier project) which could be described as cryptic and ancient. It basically displays a form, catches the input and runs an external application to process the input and then pipes the output to the user.
I would really like not to modify this file any more than is required. Would there be an easy way to just make this file magically work by copying it to some location in the CakePHP's directory and have it receive $POST etc. as usual?
I'm working in NetBeans 6.8 and I'm trying to create new connection using MySQL to an existing database. Does the .mdb file need to be in a specific location? It tells me that it cannot establish the connection.

How do you convert an existing project into an Android project in Eclipse?

What's the best way to add foreign keys to my existing tables in Rails with an underlying MySQL database? clearly the solution should be done in a migration, as I want this versioned. Otherwise I'd create the constraints myself.
I can't seem to find one, conducive response to they above. Again, the tables have already been created with previous migrations. I'm just going back now and adding referential integrity wherever it's applicable.
Could someone tell me the difference between the publishing folder location and the installation folder URL? Is there any reason why these two wouldn't be the same?

How do you programmatically generate T-SQL CREATE statements for existing indexes in a database? SQL Studio provides a "Script Index as-Create to" command that generates code in the form:
IF NOT EXISTS(SELECT * FROM sys.indexes WHERE name = N'IX_myindex')
CREATE NONCLUSTERED INDEX [IX_myindex] ON [dbo].[mytable]
(
[my_id] ASC
)WITH (SORT_IN_TEMPDB = OFF, DROP_EXISTING = OFF, IGNORE_DUP_KEY = OFF, ONLINE = OFF) ON [PRIMARY]
GO
How would you do this programmatically (ideally through Python)?

In many windows installers the last step is called "removing backup files".
I understand that to provide transactional integrity of the install process some "backup files" could've been created and have to be cleaned up.
What I do not understand is why on many occasions this step takes considerably longer than the rest of the installation.
Any idea why?
