Featured on ScraperWiki

I’ve been using the online (sorry, cloud) open data scraping tool, ScraperWiki for some time now.

We’ve written a bunch of scrapers that are being used by PlanningAlerts and I’ve also created a few for other bits of data I am interested in or that I’ve been commissioned by clients to write.

For the second time, my creations have been featured on the front page, isn’t that nice? :)

I’ve been meaning to write this blog post for a long time and hearing in Jonathan Holmes’ recent article on The Drum that he doesn’t have a complex password and reuses that password over and over again tipped me over the edge. I hear this time and time again and it doesn’t need to be this way.

Here’s three simple steps that will massively increase your online security. It won’t make you bullet-proof and you should still do all those other things security people have been telling you for years but these are really easy to do, anyone can do them and they plug the biggest security hole that people have these days – insecure and reused passwords.

Step 1. Create a complex password

Wait! Don’t stop reading because you think it’s going to be hard to remember – complex passwords can be easy to remember.

A software tool called pwgen can generate complex passwords that are pronounceable and therefore easier for us humans to remember.

There’s an online version you can use to generate these. Go off and generate one now and use it for your most important online tool, such as your Gmail account.

Step 2. Start using a password manager

If you’re reading this, chances are you have heaps of username and password combinations for all of the online services you use. To manage these you need to be using a password manager.

Password managers generate complex passwords for services that you don’t need to remember. When you open your password file you just enter one master password and it unlocks all of your other varied, complex passwords.

I use KeePass because it is open source and works on the different platforms I use (Linux and Android). I also use Dropbox to ensure it’s synchronised between all my computers and is always available for download over the Internet.

Go and download it now and use the password you generated in the last step as your master password.

Step 3. Move all of your passwords into your password manager

This sounds hard but the trick is not to go around laboriously changing all of your passwords up front. Whenever you touch a service (e.g. login to Twitter, upload photos to Flickr, etc.), just go to your settings page and use your password manager to generate a new password. It’ll take you 30 seconds.

Off you go – go and change a few now. You’ll feel more secure right away.

Update:

Jonathan Holmes responds, “easy! You don’t understand how freaked out people like me get when confronted by something like KeePass“. That’s a fair point and I feel embarrassed I’ve done the stereotypical geek thing and assumed something easy for me wouldn’t be difficult for a non-geek.

I’m off to eat some humble pie :) In the mean time, hopefully these instructions at least inspire some geeks to fix up their own online security and, in finest nerdy tradition, show their friends and family.

In less than a week I’m off to DrupalDownunder for work as the company I work for has started to look at using more Drupal in the work they do for clients.

Given that I’ve not delved too deep into Drupal and certainly never developed on it, I thought I had better find out a bit about it before the conference.

I decided to write a module similar to oa4wp that displays your MP’s most recent speeches in a block. After a few hours hacking on Sunday afternoon, here it is:

OpenAustralia Drupal in a content block

I was pleased to get something usable in such a short amount of time and found the development reasonably straight-forward, despite the documentation for developers not really being there yet for version 7.

The block also works quite well as a sidebar, depending on what you want to use it for.

Install it, just like any other module, by downloading it and putting it in its own directory in the sites/all/modules folder of your Drupal site.

Despite using Gnome for ages, I’ve never bothered to work out how to type special characters, like ™ or ©. I’ve normally just opened the Character Map application and copied from there – obviously this is a bit of a round about process.

I finally decided to look it up and it’s as simple as: Ctrl-Shift and the character code from Gnome’s Character Map application.

So to type ™, go to Applications > Accessories > Character Map. Then note the character code:

Hold down Ctrl + Shift and type u2122. Simple.


LUKS is the standard for Linux hard disk encryption. The following few commands are all you need to encrypt your next external hard disk or USB key on a Debian-based distribution like Ubuntu.

Installation

Install the required software and load the module into the running kernel without restarting:

1
2
sudo aptitude install cryptsetup
sudo modprobe dm_crypt

Drive creation

Set up encryption on the disk and mount it:

1
2
3
4
sudo cryptsetup luksFormat /dev/sdb1
sudo cryptsetup luksOpen /dev/sdb1 external
sudo mkfs.ext4 /dev/mapper/external
sudo mount /dev/mapper/external /mnt

Mounting

How to mount the drive:

1
2
sudo cryptsetup luksOpen /dev/sdb1 external
sudo mount /dev/mapper/external /mnt

Unmounting

How to unmount the drive:

1
2
sudo umount /mnt
sudo cryptsetup luksClose external
