Difference between using bean id and name in Spring configuration file

Is there any difference between using an id attribute and name attribute on a <bean> element in a Spring configuration file?

Using different Web.config in development and production environment

I need to use different database connection string and SMTP server address in my ASP.NET application depending on it is run in development or production environment.

The application reads settings from Web.config file via WebConfigurationManager.AppSettings property.

I use Build/Publish command to deploy the application to production server via FTP and then manually replace remote Web.config with correct one.

Is it possible somehow simplify the process of deployment? Thanks!

How to fix: Handler "PageHandlerFactory-Integrated" has a bad module "ManagedPipelineHandler" in its module list

I am configuring an MVC 3 project to work on a local install of IIS and came across the following 500 error:

Handler "PageHandlerFactory-Integrated" has a bad module "ManagedPipelineHandler" in its module list.

It turns out that this is because ASP.Net was not completely installed with IIS even though I checked that box in the "Add Feature" dialog. To fix this, I simply ran the following command at the command prompt

%windir%\Microsoft.NET\Framework64\v4.0.30319\aspnet_regiis.exe -i

If I had been on a 32 bit system, it would have looked like the following:

%windir%\Microsoft.NET\Framework\v4.0.21006\aspnet_regiis.exe -i

My question is, is there a way to install IIS on a windows 7 box to use .NET 4.0 (MVC 3) without taking this extra step?

Difference between vs

I'm learning Spring 3 and I don't seem to grasp the functionality behind <context:annotation-config> and <context:component-scan>.

From what I've read they seem to handle different annotations (@Required, @Autowired etc vs @Component, @Repository, @Service etc) but also from what I've read they register the same bean post processor classes.

To confuse me even more, there is an annotation-config attribute on <context:component-scan>.

Can someone shed some light on these tags? What's similar, what's different, is one superseded by the other, they complete each other, do I need one of them, both?

How to import a module given the full path?

How can I load a Python module given its full path? Note that the file can be anywhere in the filesystem, as it is a configuration option.

What should I set JAVA_HOME to on OSX

Many Java applications that use shell scripts to configure their environment use the JAVA_HOME environment variable to start the correct version of Java, locate JRE JARs, and so on.

On OSX 10.6, the following paths seem to be valid for this variable

/Library/Java/Home
/System/Library/Frameworks/JavaVM.framework/Home
/System/Library/Frameworks/JavaVM.framework/Versions/Current

Some of these are symlinks to the actual current VM (as defined in the Java Preference pane).

But which one should be used—or is it okay to use any of them?

Error message "Forbidden You don't have permission to access / on this server"

I have configured my Apache by myself and have tried to load phpMyAdmin on a virtual host, but I received:

403 Forbidden You don't have permission to access / on this server

My httpd.conf

#
# This is the main Apache HTTP server configuration file.  It contains the
# configuration directives that give the server its instructions.
# See <URL:http://httpd.apache.org/docs/2.2> for detailed information.
# In particular, see 
# <URL:http://httpd.apache.org/docs/2.2/mod/directives.html>
# for a discussion of each configuration directive.
#
# Do NOT simply read the instructions in here without understanding
# what they do.  They're here only as hints or reminders.  If you are unsure
# consult the online docs. You have been warned.  
#
# Configuration and logfile names: If the filenames you specify for many
# of the server's control files begin with "/" (or "drive:/" for Win32), the
# server will use that explicit path.  If the filenames do *not* begin
# with "/", the value of ServerRoot is prepended -- so "logs/foo.log"
# with ServerRoot set to "C:/Program Files (x86)/Apache Software Foundation/Apache2.2" will be interpreted by the
# server as "C:/Program Files (x86)/Apache Software Foundation/Apache2.2/logs/foo.log".
#
# NOTE: Where filenames are specified, you must use forward slashes
# instead of backslashes (e.g., "c:/apache" instead of "c:\apache").
# If a drive letter is omitted, the drive on which httpd.exe is located
# will be used by default.  It is recommended that you always supply
# an explicit drive letter in absolute paths to avoid confusion.

#
# ServerRoot: The top of the directory tree under which the server's
# configuration, error, and log files are kept.
#
# Do not add a slash at the end of the directory path.  If you point
# ServerRoot at a non-local disk, be sure to point the LockFile directive
# at a local disk.  If you wish to share the same ServerRoot for multiple
# httpd daemons, you will need to change at least LockFile and PidFile.
#
ServerRoot "C:/Program Files (x86)/Apache Software Foundation/Apache2.2"

#
# Listen: Allows you to bind Apache to specific IP addresses and/or
# ports, instead of the default. See also the <VirtualHost>
# directive.
#
# Change this to Listen on specific IP addresses as shown below to 
# prevent Apache from glomming onto all bound IP addresses.

How to define custom configuration variables in rails

I was wondering how to add custom configuration variables to a rails application and how to access them in the controller, for e.g I wanna be able to define an upload_directory in the configuration files say development.rb and be able to access it in one of my controllers.

Secondly I was planning to have S3 support for uploads in my application, if i wanted to add a yaml file with the s3 access, secret key, how do I initialize it in my Rails App and how do I access the values that I have defined in that config file.

Performance differences between debug and release builds

I must admit, that usually I haven't bothered switching between the Debug and Release configurations in my program, and I have usually opted to go for the Debug configuration, even when the programs are actually deployed at the customers place.

As far as I know, the only difference between these configurations if you don't change it manually is that Debug have the DEBUG constant defined, and Release have the Optimize code checked of.

So my questions is actually twofold:

1. Are there much performance differences between these two configurations. Are there any specific type of code that will cause big differences in performance here, or is it actually not that important?

2. Are there any type of code that will run fine under the Debug configuration that might fail under Release configuration, or can you be certain that code that is tested and working fine under the Debug configuration will also work fine under Release configuration.

Eclipse fonts and background color

I have been trying to change the background color of eclipses windows to black and customize the font colors. There doesn't seem to be a way to do this at least not an obvious way. I am using version 3.3.

Does anyone know how to do this or of any plugin's that might be able to assist in doing this?

How do I prevent a Gateway Timeout with FastCGI on Nginx

I am running Django, FastCGI, and Nginx. I am creating an api of sorts that where someone can send some data via XML which I will process and then return some status codes for each node that was sent over.

The problem is that Nginx will throw a 504 Gateway Time-out if I take too long to process the XML -- I think longer than 60 seconds.

So I would like to set up Nginx so that if any requests matching the location /api will not time out for 120 seconds. What setting will accomplish that.

What I have so far is:

    # Handles all api calls
    location ^~ /api/ {
        proxy_read_timeout 120;
        proxy_connect_timeout 120;
        fastcgi_pass 127.0.0.1:8080;
    }

Edit: What I have is not working :)

How to set the java.library.path from Eclipse

How can I set the java.library.path for a whole Eclipse Project? I'm using a Java library that relies on OS specific files and need to find a .dll/.so/.jnilib. But the Application always exits with an error message that those files are not found on the library path.

I would like to configure this whole project to use the library path. I tried to add the path as a VM argument to some run configurations in eclipse but that didn't work.

Where to place AutoMapper.CreateMaps?

I'm using AutoMapper in an ASP.NET MVC application. I was told that I should move the AutoMapper.CreateMap elsewhere as they have a lot of overhead. I'm not too sure how to design my application to put these calls in just 1 place.

I have a web layer, service layer and a data layer. Each a project of its own. I use Ninject to DI everything. I'll utilize AutoMapper in both web and service layers.

So what are your setup for AutoMapper's CreateMap? Where do you put it? How do you call it?
