• How to communicate between service controller and a service/daemon?

  - by Sorin Sbarnea

  It is easy to display the status of a Windows service or to control it (start/stop) from a GUI application but the question if how about receiving/sending notifications from the service? Like: service telling to the user monitoring it that it needs attention. Please consider that you can have several controllers started at any time in a multi-user environment. Do you know an example(open source) for this kind of communication? Extra points for a platform independent solution :)

• ideas: per-file authentication in order to download

  - by suIIIha

  i would love to use mod_xsendfile but i live in a shared environment which does not provide such a module. processing large files such as videos through a server-side script and sending it to the browser that way seems to be unacceptable in my case, so i am looking for a way to enable per-file authentication in such a way that is not going to consume resources much. nobody shall know what the actual path is to the file they are downloading. please suggest how to do that.

• How to relink existing shared library with extra object file

  - by awy

  I have existing Linux shared object file (shared library) which has been stripped. I want to produce a new version of the library with some additional functions included. I had hoped that something like the following would work, but does not: ld -o newlib.so newfuncs.o --whole-archive existinglib.so I do not have the source to the existing library. I could get it but getting a full build environment with the necessary dependencies in place would be a lot of effort for what seems like a simple problem.

• java alternative for phpMyAdmin

  - by rcourtna

  I find myself working in an environment where all I have access to is Tomcat + MySQL. No Apache, no PHP. I'm looking for a web interface to MySQL that will run under Tomcat (can't be a desktop interface, as the mysql port is not accessible). I'm tried jMyAdmin and javaMyAdmin. I can't get either to work, and both lack documentation and community support. Can anyone make a recommendation please?

• Use a Datamodule in a Service Application

  - by O Engenheiro

  I wrote my Win32 App to test and debug. I've created a datamodule with all functionality needed to run the TCP sockets and IBDatabase components. After successfully testing the Datamodule in the Win32 application environment I am trying to hook the Datamodule into a Service Application template that I created, I can get nowhere in getting it to run. Could someone indicate whether this strategy of using a Datamodule with Component functionality encapsulating the primary service functions is workable and give a simple template example of how to hook it up if it is??

• Sending test emails in development without spam or rejection issues.

  - by Micah Burnett

  I run my development environment in a VM and need to test the delivery and appearance of emails from my applications. The problem is when my SMTP server starts delivering a lot of mail to my corporate email account, the server is soon rejected as a source of spam. Of course, the major Internet email providers will also never accept email from such a server. I've delivered to a specified pickup directory and open in outlook express, but the problem is images always display as broken images.

• Tuning garbage collections for low latency

  - by elec

  I'm looking for arguments as to how best to size the young generation (with respect to the old generation) in an environment where low latency is critical. My own testing tends to show that latency is lowest when the young generation is fairly large (eg. -XX:NewRatio <3), however I cannot reconcile this with the intuition that the larger the young generation the more time it should take to garbage collect. The application runs on linux, jdk 6 before update 14, i.e G1 not available.

• DRY way of calling a method in every rails model

  - by Tim

  Along the same lines as this question, I want to call acts_as_reportable inside every model so I can do one-off manual reports in the console in my dev environment (with a dump of the production data). What's the best way to do this? Putting acts_as_reportable if ENV['RAILS_ENV'] == "development" in every model is getting tedious and isn't very DRY at all. Everyone says monkey patching is the devil, but a mixin seems overkill. Thanks!
