How to use Alt + Ctrl + Del in a Windows Virtual machine

If you are in a console of  a Windows virtual machine hosted on the Virtual Center or ESX and want to use Alt + Ctrl + Del to unlock the screen, This is how you do it since hitting  Alt + Ctrl + Del will only lock your screen and not the virtual machine(That's frustrating, I know..)

So in a vSphere this is how you do it. Go to the console tab of the virtual machine and select Inventory > Virtual Machine > Guest > Send Alt+Ctrl+Del as shown in the image below.

Alt+Ctrl+Del in a Virtual Machine in VSphere

In remote desktop we should use Alt+Ctrl+End instead

How to create dummy files in Linux

If your test case requires you to create a large dummy file or many dummy files in linux and Google or Yahoo landed you here, then you have come to the right place.

In Linux you can create a large file with just a one line command. Here's how.

  

Creating one large file

dd if=/dev/zero of=/home/1GBtestfile.img count=1000000 bs=1024

This will create a 1GB file named 1GBtestfile.img in the home directory

dd if=/dev/zero of=/50GBtestfile.img count=50000000 bs=1024

This will create a 50GB file named 50GBtestfile.img in the / or root directory

To check the size of the file which is being created, in a new ssh session type
du -hs /home/1GBtestfile.img

Creating many dummy files

Create a shell script named filecreator

# vi filecreator

Paste the following to create 10 files in the same directory

#!/bin/bash
    for i in $(seq 0 10);
    do
        echo -n "file${i} ";
        dd if=/dev/zero of=file${i} bs=1024 count=2 2>&1;
    done

Wright and Quit by typing wq

Rename the file to a .sh file
# mv filecreator filecreator.sh

Run the script
# ./filecreator.sh 

To count the number of files in a directory
# ls -l | wc -l

Bug in Facebook login page

First of all I love Facebook. But this Facebook bug has been around for more than one and a half years now and sadly it has not been fixed even after informing Facebook in 2009 January under the subject "Resizing Welcome/Login page in Firefox-3 does not render the background". For a site used by millions of users daily, I was quite surprised to find this bug on Facebook's login/welcome page.

I checked this bug in Firefox 3.6, Internet Explorer 8 and Chrome 5, but I am sure this can be reproduced in all other browsers. Even thought the bug is in the login page, It's not a security threat of any sort and it seems to be a CSS styling issue.

Steps to reproduce:

1. Go to http://www.facebook.com/ (if you are logged in to Facebook you need to log out first)
2. Make sure the browser is maximized and click on the "Restore Down" button next to the red close button on the top
3. Move the horizontal scroll bar to the right so that the Sign Up area can be seen.
4. BoooM!! Now you see that the background image does not get rendered. This make the input fields to look out of place.(See images below)
