When I code in Java, I can use tools like JRebel to allow me to see changes immediately without restarting the server. (I'm embedding the JVM into a c application, so I don't want to constantly restart the c application for every Java source code change)
Does Mono have something similar?
You can do something similar by using application domains (load the new code in a new appdomain, unload the old one etc).

I'm working on a project and what I want to do, I have installed lighttpd on my raspberry pi which is running xbian and I have created asp file using to control xbmc by using some .net library.I got mono application as well to control xbmc and I want to send command or signal or message from lighttpd to the running mono application
How to do this, do i have to use any rpc, pipe etc.
thank you
You could either use the lua or php plugin, parse the requests there and run your stuff accordingly.
A rather difficult alternative would be to write a plugin yourself and make that do whatever it needs to do (though this will require at least decent C skills as well as security awareness) http://redmine.lighttpd.net/projects/1/wiki/HowToWriteALighttpdPlugin
https://www.mono-project.com/docs/web/fastcgi/
Separately, if files are downloading instead of being processed, then ensure that you have configured lighttpd.conf mimetype.assign
The great thing about PHP is that if you have something like
clothes.com, clothes.com/men.php, clothes.com/women.php
Then if you only edit the men's page, only that particular "app" will be restarted.
But on rack/Sinatra I have to touch the restart.txt file to restart the ENTIRE website.
Is there a way around this problem, so that users browsing other parts of the site wont have any problems while another part of the site get edited?
(i'm using mod-passenger on Apache, not that it's important..)
This would be true in all cases anyway for editing (non-inline) views (not layouts).
Aside from that, if you're really worried about this then I'd suggest using versioned folders to hold the application code. When you do a deployment, change the proxy to point at the newer version. Those who had already made requests will remain on an instance of Apache and the application that is already running, as long as their request remains alive, and seemlessly (unless you've broken something with the code) move to the new code on the next request.
It's also a convenient way to rollback to the/a previous version quickly and easily.

I'm learning in VB.NET. This is my first language.
I'm trying to build a launcher for an application with uncertain registry write location. I'm working on makeing the application portable. (app is based on low .NET framework for compatibility)
I looked for different methods like forcing registry virtualization or use registry virtualization through an api. (Thinking I can offload the writes if they're consolidated.)
I was also thinking that I could monitor the registry for any writes by a certain PID. I've also looked for an application that did this. Redirected any writes like sandboxie does. But with no luck.
So if I need to add more details tell me and thanks for the help.
You might check out a product like VMWare ThinApp or other Application virtualization tools, which will do this automatically for you with no need to write any code.
Maybe its just me, but this sounds like a very complicated thing you are trying to do in your first program.
I'm trying to find a decent standalone webserver that I can load up on a jump drive.
My wife is a photographer, and I'd like to present the clients with their images on usb. When they plug it in, I'd like a web page to load up, and run some jQuery magic to show them a nice carousel of all there images.
So far, this is all fine since it can all be done client side and doesn't need a server at all.
The problem I'm facing is that I'd like some server-side code to be able to read the images out of the directory so that once the interface is built, I don't need to manually create all of the <img /> tags.
If it was primarily going to be used in a Windows environment, I'd have no problem going with IIS Express, since I'm mainly a .NET MVC developer and this would be perfect for me... However, the fact of the matter is that a large amount of our client base is also OS X users.
I did find this Java one jlHttp, and I also found this thread here on SO, but I don't think I understand enough about either one of them to accomplish what I'm looking for.
Thanks in advance for your suggestions.
I'm looking for the same thing, and the two best options I've found were Flying Ant cd web server and Stunnix. Of the two, Flying Ant is cheaper, and I've tested it with success on my project.
I found Mongoose very convenient for this exact purpose. It's crossplatform, lightweight and requires minimum configuration. You may be interested in this project that uses Mongoose to display pictures in a folder tree or FTP directory.
How about Node.js
It says it runs on Linux, OS X, and Windows.
If you look at the Linux ecosystem (especially the Ubuntu and Alestic EC2 images) there is a common technique where the VMs are pre-configured to look at the EC2 user-data and use it as a boot script. The nice thing about this approach is that you can write a boot script that further provisions your machine, allowing you to avoid making a new image every time your software that runs on the machine changes.
I want to do the same thing for Windows, but given that I'm an Mac and Linux guy, I'm a bit lost on where to start. My requirements are:
This must run on Windows Server 2008
A bootstrap script needs to start when the machine boots up, read the user-data file by pulling down the contents http://169.254.169.254/1.0/user-data
The bootstap script then needs to run the contents of that file as if it were a script
The script embedded in the user-data needs to run in such a way that it has access to the desktop environment (ie: it can launch a browser, etc).
I'm not quite sure how services work in Windows or if I need to enable auto-login, so any advice here would be appreciated. The ultimate goal is to run a Java program that launches some custom software that in turn launches a web browser (IE, Firefox, etc) and is capable of taking screenshots.
The screenshot part is interesting, because in the past when I've tried this the only way I could get something other than a black screen was to have UltraVNC or RealVNC boot up as a service, though I don't know why that helped.
I'm looking for answers to three specific questions, as well as any general advice:
Should I be focussing on a Windows service or auto-login + bat file in the "Startup" folder?
If I use a Windows service, is there anything special that I need to do to make sure desktop access and/or screenshots are available?
Do you recommend any tools for common Linux commands, like curl or wget? Last time I used Windows I used Cygwin a lot, but is there something more appropriate to use here?
I have not tried auto-login on Windows instances in EC2, but here's the support document on how to enable it.
We boot-strap our Windows instances using a custom AMI with a custom Windows 'install' service already installed. The boot-strap installer reads a URL from user-data at startup. The URL points to a ZIP file stored in S3. The installer then downloads, un-zips, and executes the actual application installer -- in our case a simple CMD fie.
This setups allows us to have one base AMI and then be able to easily overlay 15+ different application configurations (without having to rebuild the AMI). If you only have one application configuration this may be overkill for your situation.
The only trouble we ran into was having our installer service start to early -- changing the service startup mode to "Automatic Delayed" fixed that issue.
We wrote our boot-strap installer in Java, launched via YAJSW, because we're comfortable with it. If you just want a few simple Unix tools, most are available pre-compiled for Windows, for example wget.
For something completely different, you could try PsExec to configure the instance after it has booted.
You can try using RightScale's free developer account to create plain Powershell scripts and associate them with your Windows instances to run at boot time. The RightScale dashboard solves exactly the problems you are trying to solve above.
DISCLAIMER: I work for RightScale.
As for screen capture CutyCapt is a simple tool you can point at a URL and generate an image from.
Unxutils is a great solution for those looking for unix tools on Windows. It's got the wget.exe that you're looking for, however, using Powershell to download stuff is not so bad either:
$wc = new-object system.net.webclient
$wc.DownloadFile("http://stackoverflow.com","test.html")
If you can write a batch file to do your setup, then you can run it at startup of the vm by doing this:
1. Run REGEDT32.EXE.
2. Modify the following value within HKEY_CURRENT_USER:
Software\Microsoft\Windows NT\CurrentVersion\Winlogon\ParseAutoexec
1 = autoexec.bat is parsed
0 = autoexec.bat is not parsed
As an answer to #3, I would say that you can do just about anything in a batch file that you need which includes downloading from a ftp server (but not from a http server). I am really interested in this stuff and so if you have questions, try asking me.
If you use Elastic Beanstalks you can use this:
Customizing the Software on EC2 Instances Running Windows
It uses YAML formatting standards, e.g.
packages:
msi:
mysql: http://dev.mysql.com/get/Downloads/Connector-Net/mysql-connector-net-6.6.5.msi/from/http://cdn.mysql.com/
or
sources:
"c:/myproject/myapp": http://s3.amazonaws.com/mybucket/myobject.zip
I know this is a little bit late to help out with the original post but for anyone who is still reading this one solution is to use the http://cloudinitnet.codeplex.com/ project. The service is easily installed using a powershell script and will create a local administrator account to use while running.
The goal for this project was to replace the Cloud-Init project used in Amazon Linux and Ubuntu.
