HOWTO: Disable touchpad when mouse is plugged in

My Dell M4400 laptop runs Ubuntu Linux 10.04.  When writing reports, I kept making mistakes due to hitting the trackpad during typing.  To solve this problem, I'm using this script to disable the touchpad when my favourite mouse is plugged in.  When the mouse is unplugged, the script restarts the touchpad.  Very nice.

Mac OS X Lion: Saved Versions considered harmful

Lion has a new feature designed to take safety copies of files you are editing.   But this isn't a good idea if you edit confidential documents, as it will result in copies of your sensitive documents spreading beyond the folder you put them in.  There's no easy way to disable it..

Booting Acronis True Image from a USB stick

Today I needed to restore a netbook PC from a backup image taken with Acronis True Image Home 9.0 (which is excellent). The backup image was stored on an external USB hard drive. The problem was how to boot the Acronis recovery image, as the netbook has no CD drive.

How to disable GMail's spam filter

GMail's spam filtering is usually excellent, but sometimes it can get over-zealous.  The first thing to know is that mail from people in your GMail Contacts list is never flagged as spam. So regular correspondents should be added to to your GMail Contacts.

If you want to turn off GMail spam filtering altogether, here's how...

More thoughts on Sandboxing for security

From a security perspective, perhaps today's desktop operating systems are missing the point. With the increase in carefully-targeted spear-phishing attacks, we need to change our approach if we are to stop our computers being compromised.  Firewalls, content-checkers, anti-virus programs, whole-disk encryption: these are all necessary, but they are not enough.

We must assume the worst and plan accordingly.  From time to time, you or a colleague will receive malware-infected files that will get past the virus scanner.  How can we remain secure?

Given the security threats from the Internet today, I believe that all web pages, images and documents need to be be opened inside a sandbox container by default.

Fixed: Ubuntu Server shows outdated update info

Just updated some Ubuntu 10.04.2 servers using 'apt-get update; apt-get dist-upgrade', then rebooted to find stale information displayed in the login banner, still showing lots of updates pending.  There's a simple fix for this...
  rm /etc/motd.tail
  /usr/lib/update-notifier/update-motd-updates-available --force
The system would catch up eventually anyway.  These commands just speed it up.

Easy sandboxing for Windows apps

Sandboxie looks very interesting....  Yet to try it, but have heard good things about it.  Without the cost of firing up different VMs, it is able to launch programs inside wrappers, to isolate different programs from each other (or to isolate different web pages from each other) - and to protect your Windows machine from the sandboxed program.
