It’s interesting to see how Harper’s suspension of democracy in Canada is being perceived to the south…

…and take climate action:

As the UN climate talks continue in Bali, and many countries continue trying to make progress on international agreements on dealing with climate change, Canada’s conservative government seems to have a different plan - do the bidding of big oil and sabotage all progress at the climate talks, contrary to the wishes of most Canadians. So far has Canada slipped, under the current government, from its former position as bastion of international diplomacy at the Montreal negotiations two years ago, that at the weekend Canada won the “fossil of the day” award, for doing the most to block progress at the negotiations.

It’s time to make some noise, Canada: head on over to avaaz.org and tell Harper to stop blocking the UN climate talks. It only takes a minute.

Once you’ve done that, read on for more contact details. A phone call is worth a thousand emails…

Google recently added Vancouver to Google Transit. This is extremely useful, as Translink’s own trip planner is so bad as to be almost unusable. However, one of my friends noticed something which I thought was rather amusing…

The system appears to think it is possible to walk on water.

Amazing.

The spam filtering setup on our server is pretty good - SpamAssassin with Bayesian filtering and the FuzzyOCR Plugin which I installed to deal with the rise of image-based spam last year. Still, a few email addresses that route to me are very public, and most days one or two spam messages get through the filters.

This morning I noticed a new phenomenon in my inbox. I almost moved it across into my “missed spam” folder without giving it a second thought (we train our filters with missed spam to improve the Bayesian analysis), but something caught my eye:

“That’s odd,” I thought, so I opened the pdf. (Note, in general unless you know what you’re doing, it’s a really bad idea to open attachments if you don’t know the sender or weren’t expecting something from them - it could be a virus.)

That’s right, it’s spam, in a pdf file. While spamassassin does a great job of analysing text, and even images using FuzzyOCR, no analysis is done of pdf attachments, so this one slipped through the net. (I’ve had seven copies of this so far today.)

What next? Well, if this type of spam continues (and there’s no reason to think it won’t) I expect we’ll see a pdf scanning plugin for SpamAssassin before too long. After that gains traction the spammers will undoubtedly adapt again with some new trick to avoid the filters. Rinse, and repeat.

The arms race continues…
