Unloading Assembly

Do you know that, there is no possibility to unload the assembly from the run time. The only possibility to unload the assembly is to unload the AppDomain as the CLR that binds them to respective process.
 
You might be wondering about, why one should unload the assembly at run time?
 
Though I sound strange, I feel that there could be at least 2 reasons that enforce me as a developer to unload the assembly from run time.
 
Point A) When my server is running out of space -- rarely this happens
Point B) when my application compiles a newer version of the assembly to replace the existing one.. Yes this happens often, specially with web apps. As and when you compile your project and deploy to the new location either you have to stop your iis or you have to restart your app from the iis.
 
Instead of all these manual process, I think that, developing application with the AppDomain concept and cache all the assemblies before the system resource lock my assemblies. so that you can easily deploy your web apps when any of your component is modified.
 
What do you say?

Due to the length of the blog post, will not be posting the entire draft. 1.Title of the thesis Network Intrusion Detection using Supervised Machine Learning Technique with Feature Selection 2.Introduction Intrusion Detection System, IDS, is a development which improve the network security and defending the information of the association. The IDS encourage the network chairman to recognize any malicious action on the network and alarms the executive to get the information made sure about by taking the appropriate activities against those attacks.

Common mistakes by Interviewer

Now-a-days am conducting few interviews for our organization. While sitting in the other side of the table, I've visualized why most of the interviews fail with me. But when conducting these interviews, most of the candidates are attending with self confidence that they are suitable for the mentioned role and attend without preparation. When people do some real preparation, they tend to fail due to lack of awareness at the interviewer towards interviewing techniques. Having failed in many interviews, I've learned that the interviews fail because of the following... Reflection (or) Mirroring: The interviewer tends to see self within the candidate. The interviewer starts to compare self with the candidate and evaluate. This evaluation is totally personal. The yard stick for measuring the candidature is not generalized, but influenced.   Template (or) Checklist: The interviewer has a template of a questionnaire. The interviewer measures the candidate with respect to the list of st

Keep the system active, to avoid the auto lock

Most of the corporate offices will have a policy for screen locking. While working with a long running applications at background, like the automation scripts for testing the applications, it would be difficult to maintain the unlock state of the screen. Thus, we found a technique to keep the system active with a cheating technique. Below is the powershall scripts that keeps the system active ' I am clicking on NUMLOCK for every 5 seconds to keep the system awake Set objNetwork = CreateObject("Wscript.Network")'to get user name numOfHours=inputbox("Hi " & objNetwork.UserName & ", How many hours you want me to be awake? :->") 'time variable conatins the time in hours Set WshShell = WScript.CreateObject("WScript.Shell") 'Creating an object for clicking keys from keyboard numOfMilliSecs=numOfHours*3600*1000 'converting hours to milli seconds While numOfMilliSecs>0 'runs until tym becomes zero WshShell.Send
