I’ve now gone and switched to paid hosting, and have dumped the old static site in favour of a Wordpress-powered blog on my own domain. I’ve found Wordpress to be an extremely flexible and powerful solution, far superior to Blogger, and I’m really excited about the possibilities of a self-hosted blog, so I’m really looking forward to establishing myself here! At some point I intend to create a custom theme of my own, but for now this one will do fine!
As I mentioned previously, I’ve changed the emphasis of the blog towards web development. I’ve also now made a number of other improvements - comments are now powered by Disqus, to facilitate easier sharing of posts and making it easier for people to reply to me via blog posts of their own.

- First of all, check for a list of well-known easy to break passwords to foil a dictionary attack, and reject it if it’s there.
- Then check that it’s at least 8 characters, and reject it if it’s not.
- Then implement a counter to measure how secure it is by various checks.
- Then add to the rating if it’s more than 12 characters.
- Add to the rating if it contains lowercase letters.
- Add to the rating if it contains uppercase letters.
- Add to the rating if it contains numbers.
- Add to the rating if it contains nonalphanumeric characters.
- Finally, convert the result to a percentage score and return it as an integer.
The finished article’s available here as a .zip file if you’d like to use it, or just take a look at the code. Be warned, it’s quite long due to the fact that the list of insecure passwords I used had in excess of 3,000 entries in it! It includes a very simple HTML form which will allow you to submit a function and will return a score for it via an alert() dialogue. Feel free to use it if you wish!

Personally I’m more than willing to take up the slack myself by studying independently, but I’m sure there are plenty of people who wouldn’t do so until they reach the workplace. Admittedly, the fundamentals of the language haven’t changed, but there’s plenty of stuff that’s of very little use today that I’ve had to learn when I could be learning something more useful.
So surely these texts are long overdue for a refresh? I would hope that a newer release would cover at least some of the following:
Creating a simple AJAX application.
I really don’t think there’s any excuse for the training materials being that outdated when some of their other CIW training materials are much more current.

For a while now I’ve been looking for a good free shell account provider, and the other day I stumbled across the best I’ve ever seen at http://devio.us/. They run OpenBSD, they provide pretty much everything you could want from a shell account provider, and they’ve been very willing to help so far - when I asked if they had plans to add Python support, they added it within 24 hours. If you’re looking for a good shell account provider, I suggest you give them a try.

I’ve made the tough decision to abandon Blogger and move my blog to Wordpress. For those of you that have joined me from my old blog at http://farbeyondtheedgeofreason.blogspot.com/ thank you very much for doing so!
The new blog will have a somewhat different emphasis than my old one. Rather than being a bit of a free-for-all covering Linux, programming, new websites and anything else that I think of, this blog is going to be much more focused, with web development as the main subject. That said, we’ll have to see how things work out.
I’m considering another move in a few months time, with my site at http://matthewdaly.co.uk/ becoming the new location of the blog, but that would require paid hosting, so I’m going to give Wordpress a good try first before I commit to using it.
