C# Code to change the encoding of a text file to the desired encoding

2011-03-16T11:14:00.000-07:00

This code lets you convert multiple files in a directory to the desired encoding. The reason for this utility is the source control which is being used by my client doesn't support anything other than ASCII (7 bit). By default, some of the program creates files with UTF-8 encoding, which created the problem. I wrote this small program which will convert the files in a stretch and hence might save lot of time. Enjoy!

Recycle what?

2011-03-14T14:26:00.001-07:00

While taking out the trash yesterday, I noticed that almost nobody cares about the environment in our apartment. I saw a bunch of TV 's and computer monitor left to rot. Seriously??? how many of us know most of the companies allow to recycle the old computers free???
So sad isn't it?

Have you done that? :)

2011-03-14T05:41:00.001-07:00

Hi all,

Just noticed this today during my morning commute... things we do for saving time... this guy, who was sitting right before me was enjoying a sandwich even though the bus was clearly marked as no eating.. have you done that? Let me know in the comments

Code to update the created / modified time of a file, without affecting contents

2011-03-11T11:33:00.000-08:00

I came across this ridiculous issue: The "intelligent" source control that we are using, is not allowing me to check-in the file that I modified a while back since there is a "latest file", but actually the version of the file in the source control database was old. It just had latest datestamp on it. I have to open the file VS.NET and have to save it once again to make the "modified" timestamp to the latest. I had created a small program dedicated to the bug in our source control db, to take care of this issue. Say you want to just update the time stamp, but you don't want to open or change the file, this code will come in handy.
