Interesting story in today's Times. Postman Roger Annies was getting tired of the amount of junk mail that he was delivering, so he decided to do something about it. He designed and delivered his own leaflets, full of advice on how to cut down on the amount of junk mail you recieve.

But unfortunately, the Post Office took a rather dim view of this public service. Delivery junk mail is a lucrative souce of income for the Post Office and as a result Mr. Annies has been accused of misconduct and suspended.

Trust the Post Office to put profit before customer satisfaction!

Comment Spam Again

| 5 Comments | View blog reactions

If you've tried to post a comment here over the last few days, you would have been disappointed. Over the weekend I came under another massive comment spam attack which brought my server to its knees. I was seeing a server load of over 300 (it should usually be less than 1). Even though I had switched to authenticated commenters only, the sheer number of requests on the comments program was killing the server. So I took pretty drastic action and removed execute permissions from the mt-comments.cgi program. I've just turned it back on, but I'll be watching closely over the next few days and will turn it off again if necessary.

I read something yesterday about this huge server load being caused by a problem with javascript files in MT3.2. But I can't find the article I was reading now [Update: Kevin (in the comments) points out that the article in question is here]. Apparently this problem is fixed in 3.3. I've been considering an upgrade to 3.3 recently and having done a clean installation for a friend recently I like what I've seen and I'll be aiming to upgrade this site as soon as I get back from YAPC::Europe. So hopefully the comment spam issue will get a lot better in ten days or so.

"We apologise for the inconvenience"

According to a story in today's Guardian, more than 30% of students in the UK say they believe in creationism or intelligent design. The piece makes for uncomfortable reading for anyone capable of rational thought.

In a survey last month, more than 12% questioned preferred creationism - the idea God created us within the past 10,000 years - to any other explanation of how we got here. Another 19% favoured the theory of intelligent design - that some features of living things are due to a supernatural being such as God. This means more than 30% believe our origins have more to do with God than with Darwin - evolution theory rang true for only 56%.

Academics are unsurprised

The findings come as little surprise to Roger Downie, professor of zoological education at Glasgow University. Two years ago he surveyed the views on evolution of biology and medical students there. "What was extremely worrying for students embarking on evidence- and science-based disciplines was that they were perfectly prepared to say they had rejected it not on the basis of evidence but on the basis of their religious beliefs," he says.>

And

Steve Jones, professor of genetics at University College London, [...], has been talking about evolutionary biology in schools for 20 years. For the first 10 of those he was lucky to find one student in 1,000 expressing creationist beliefs. "Now in any school I go to I meet a student who says they are a creationist or delude themselves that they are."

He blames the influence of Christian fundamentalists in America and political correctness among teachers here who, he says, feel they have to give a reasonable hearing to beliefs held by people from other cultures, particularly Muslims.

Let's be clear here, I'm all for being open-minded and listening to other people's points of view. But when those points of view include positing the existance of an invisible sky-pixie who magicked the whole universe into existence, then surely the only sane response is to laugh at them. Very loudly.

Light Bloggage

I've just realised that it's two weeks today that I go off to this year's YAPC::Europe and I still have two talks to write - one of which is a three hour tutorial. So don't expect much writing from me over the next couple of weeks. I'll be far too busy working on other things.

In the meantime, Nik's series of posts on the benefits of OO programming looks like it's going to be well worth reading. The first two articles (on data hiding and separation of concerns) are already available and three more will appear over the next few days.

Hiveminder

I've never really got on well with web-based todo lists. I've tried a number of them over the last couple of years and I always end up with a stagnating list and nothing much getting done.

But I'm going to try again with Hiveminder. It looks like it might well pitched be at just about the right level to be useful to me. As a bonus, it's written by people that I know from Best Practical (who also produce the best ticketing system I've ever used).

So I've signed up and I'll be trying it out for a few weeks. I'll let you know how I get on.

I'm probably being very slow here, but I've recently discovered three useful tools that del.icio.us gives you.

  • Your network - allows you to monitor the bookmarks of any users you want. You can also see which users are monitoring your bookmarks.
  • Your inbox - gives you a list of all bookmarks that are published with particular tags that you are interested in.
  • for: - allows you to tag any bookmark for the attention of another del.icio.us user. For example, if you tag anything as "for:davorg" then it will appear on my "links for you" page[1].

All in all, these three features make del.icio.us far more useful that I thought it was. And, of course, each of these features produces an RSS feed so I can monitor them on Bloglines.

[1] I wonder if that will lead to my inbox filling up with rubbish.

As an experiment, I've made it so you need to be a registered user to comment on this blog. To comment, you'll need a Typekey username.

I really don't want to do this as, for me, having random people commenting on entries is one of the great pleasures of running a blog. But the amount of processor power being wasted by comment spam was getting unreasonable. I'm investigating alternatives and I hope to allow free blogging again soon.

Online Shopping

| 1 Comment | View blog reactions

When you are designing a shop, whether online or in the real world, one of the most important design criteria is that you want to make it as easy as possible for your customers to find the products that they want to buy. One of the best counter-examples for this is the London bookshop, Foyles. For many years they insisted on organising their shelves by publisher rather than the more usual arrangement which is by subject matter. This meant that if you wanted, for example, to buy a book on web design then you had to explore each publisher's section to see if they published any books on that subject. I know many people (myself included) who wouldn't shop in Foyles until they rearranged the shop a few years ago.

When there are alternative ways to organise your products, the skill is in knowing which arrangement is going to be most useful to your customers. Are most people looking for books goingto be looking for books on a particular subject or books by a particular publisher? In most shops you don't have the space to have more than one classification on display so you have to pick one.

Online, it's different. Your inventory is just a database. You are free to put as many different front ends on that database as you want. Amazon can very easily allow customers to browse by subject matter, by publisher, by author or by any number of alternative classifications. It's just a case of creating a new query against the database.

Not all online shops have worked that out though. I've written previously about how I enjoyed buying shoes from Cloggs. I've since discovered that I there is another, less helpful, side to the Cloggs site.

On my previous visits, I had been shopping in "publisher" mode. I knew I wanted Dr Martens shoes. On another visit I knew I wanted Levis jeans. And the Cloggs site made those purchases easy. They had a Dr Martens page and a Levis page. I could just choose the exact products that I needed. Recently I went back with a far more vague idea of what I wanted. I wanted to buy some sandals and I didn't really care who they were made by. I drilled down through the web site to "Guys" (I know!) and "Footwear". But that's where it went wrong. I was presented with a list of all of the brands of mens shoes that Cloggs sell. To get more detail I had to visit each brand's page individually. It took ages. And I still didn't find what I wanted.

Cloggs have missed an important point about being on the web. Their site is like the (old style) Foyles. Their classification works for some (probably a small number) of their visitors, but not for the majority. And it doesn't need to be like that. On the web you have the flexibility to present your data in many different ways. You can tailor your web site to any customer's requirements. Whoever designed the software that powers their site wasn't thinking about the web. They were apparently still thinking of physical shops where one classification system is the norm.

I don't mean to pick on Cloggs specifically. I'm sure there are many other online shops that work the same way. Maybe even most online shops work like that. But it's shortsighted. It doesn't exploit the power of the web. A virtual shop (and that is what we're talking about) can be anything that you want it to be. Unlike physical shops, it's not constrained by the size of the building.

All of which got me thinking. Have any shops tried allowing customers to define the classification of the products? I'm thinking of a site where customers can add tags to products and other customers can search by either shop-defined tags ("men", "footwear", "dr martens", "sandals") or by customer-defined tags ("what david beckham was wearing last week"). I sounds to me like a powerful way to run an online shop, but I can't find any evidence of anyone trying it.

Maybe I need to see how hard it is to thrash out a prototype.
