Problem: Somehow the “Software & Drivers” option does not show up when I try to download the printer driver of HP LaserJet Pro MFP M127fn from the official HP website using Chromium, Firefox, Opera and most web browsers on Linux.
Solution: Use Konqueror on Linux or another OS.
1. Install poppler-utils
2. To extract original embedded images:
$ pdfimages -j <file.pdf> <to_dir>
3. To extract text:
$ pdftotext -j <file.pdf>
After upgrading Ubuntu 11.04 (Natty Narwhal) to 11.10 (Oneiric Ocelot), GVim starts to behave weirdly.
6 May 2012 UPDATE: Issue persists even after upgrading to 12.04 (Precise Pangolin)! 🙁
Symptoms:
** (gvim:5933): IBUS-WARNING **: Create input context failed: Timeout was reached.** (gvim:5760): WARNING **: Unable to register window with path '/com/canonical/menu/5C00024': Timeout was reachedWorkaround:
Run gvim -f instead of just gvim.
Put this in your .bashrc if you don’t want to add -f all the time, or if you already have other aliases using gvim and you don’t want to change all of them:
gvim(){ setsid /usr/bin/gvim -f "$@"; }
Scenario:
VirtualBox version = 4.0.12
Guest OS = Win 7
Host OS = Linux Mint 9 Isadora (based on Ubuntu)
Perform these tasks on all the Win 7 local hard-disks:
Shutdown the Win 7 VM, then run this command on Mint:
$ VBoxManage modifyhd win7.vdi --compact
That freed up 5GB of space for me, a 20% reduction.

PROBLEM : My “Contact Form” in Drupal (v6.14) was not delivering any email to my mailbox. No error was indicated in Drupal logs.
SOLUTION : Turned out my web hosting company had to move my domain name record from /etc/localdomains to /etc/remotedomains.
Here’s a php script to test the sending of email:
<?php
$to = "[email protected]";
$subject = "Test mail";
$message = "Hello! This is a test message.";
$from = "<name>@<your domain>";
$headers = "From: $from";
mail($to,$subject,$message,$headers);
echo "Mail Sent.";
?>
