Getting a new HTC One left me wondering how will I move Google Authenticator from my HTC Legend, I didn’t want to do everything all over. To my amazement I found Google has come up with a solution for a situation like this, it’s the “Move to a different phone” option in 2-step authentication setting page. It was a breeze switching to a new phone. Install Google Authenticator on your new phone and follow the “Move to a different phone” link.

Monitor Files & Directory For Modifications With PHP
One can monitor for changes to files & directories, including events like open, close, new file, delete, rename & all other file/directory operations.
The following code snippet should be self-explanatory:
<? $data_file = '/var/data/my_data_file.txt'; $inotify_fd = inotify_init(); $watch_descriptor = inotify_add_watch($inotify_fd, $data_file, IN_OPEN); while (1) { $events = inotify_read($inotify_fd); $filepath = $events['name']; print "File opened"; } inotify_rm_watch($inotify_fd, $watch_descriptor); fclose($inotify_fd); ?>
List Modified Filenames In Git
I was working on a few enhancement features of an existing project, after a few weeks work I was required to make some completed features live, so I was wondering what all files have been modified. So the Git versioning came to help, and by specifying two commit SHA1s I was able to retrive the list of files modified between the commits. Here’s how to do it,
$ git diff --name-only afd98 a3d55 program.pl list.pl Docs.pm
Monitor Directory For New Files With WSH
Sajal wanted to monitor a directory, detect new file(s) and open them in their associated applications, I remember monitoring directory for changes in Linux in a Perl script. Doing something similar on Windows it seemed tough, but a after a little pondering I remembered about Windows Script Host (WSH), and after a bit of googling, coding, trial and errors, I came up with a script which does all that is required, it’s written in VBScript.
strDrive = "D:" strFolder = "\\dropbox\\downloads\\" strComputer = "." intInterval = "5" ' Connect WMI service Set objWMIService = GetObject("winmgmts:" _ & "{impersonationLevel=impersonate}!\\" & _ strComputer & "\root\cimv2") ' build query strQuery = "Select * From __InstanceCreationEvent" _ & " Within " & intInterval _ & " Where Targetinstance Isa 'CIM_DataFile'" _ & " And TargetInstance.Drive='" & strDrive & "'"_ & " And TargetInstance.Path='" & strFolder & "'" ' Execute notification query Set colMonitoredEvents = objWMIService.ExecNotificationQuery(strQuery) ' get a shell application object Set WshShell = WScript.CreateObject("Shell.Application") Do Set objLatestEvent = colMonitoredEvents.NextEvent ' strip out the real path Response = Split(objLatestEvent.TargetInstance.PartComponent, "=") ' remove slash & quotes FileName = Replace(Response(1), """", "") FileName = Replace(FileName, "\\", "\") ' open the file in it's associated program WshShell.ShellExecute FileName, "", "", "open", 1 Wscript.Echo FileName Loop
Force Download Specific Files with Apache & Htaccess
At time we want visitors to download instead of viewing the file instead of viewing inside their browser. As a visitor I have faced problems with PDF files at many sites where I wanted to download the PDF file and view it separately because viewing the PDF inside the browser slows down the browser and sometimes causes the browser to crash.
So, If you want to force people to download a file or all files in a specific directory and so on, if is very easy to do so with the help an Apache directive which sets the response header ‘Content-Disposition’ to ‘attachment’, see the examples below:
<Files *.pdf> Header set Content-Disposition attachment </Files> <Directory /var/www/html/images> Header set Content-Disposition attachment </Directory>

Browsing privacy at public places & work
Many times we run into situations where we are required to use a public or a friend’s computer for work or personal work, like paying bills, buying stuff online etc, with this comes a privacy problem of privacy where you might accidentally leaving browsing/download history, login cookies (i.e. remember me/stay signed in etc) or chances of browsers saving form data & passwords. Private browsing or Incognito mode as some browsers feature it is the answer to the problem.
