Here’s the ultimate proof :

One can clearly see that on weekends the number of unique visitors of my blog drops drastically to about 40-50% of the working week average.

And yes, that is an almost perfect 5+2 pattern, which I’m observing for many months, like a week-long circadian rhythm. “Almost perfect” must be due to the differences in time zones.

I wonder if the same pattern is characteristic for most web-sites… That is, if people mostly do the browsing at work, and not at home.

Anybody wants to share the secret cycles of one’s blog audience?

SecuriTeam has an old, but still very useful article on SQL injection.

I’ve created a PDF of that article, containing some of the comments (all the ‘thank-you’ and ‘help-me-hack’ comments were removed): sql injection walkthrough pdf download.

Note: there were no specific license terms attached to the article; I believe that the word “free” on the SecuriTeam site logo refers to the “right of free use and copying”. If you know this is not the case – please let me know to remove this PDF from public access. (see Brian’s comment)

Today I had a task of displaying random node in a Views-generated sidebar block.

This is how to do that in Drupal 7 (Views 3):

1. edit the view which makes the block available (follow http://your.site/admin/build/views/viewname/edit)
2. in the Sort Criteria section (under Filter), look for and add Global:Random.

This is how to do that in Drupal 6 (Views 2):

1. edit the view which makes the block available (follow http://your.site/admin/build/views/viewname/edit)
2. in the Sort Criteria section, add the Random criteria.

It can’t be simpler than that.

After trying several of the kind, I found CHXO email address to image converter a reliable and working one.
It supports transparent PNGs, and just works. Also, it comes with a complete PHP source, so it looks like you can embed it into your own web-applications. (As it is GPLed, I’ve saved a copy for myself.)

For Gmailers, there’s a nicer generator.

If you’d like to convert larger amounts of text to images, then use hidetext.net:

The following sites are available:

http://protists.ensembl.org
http://metazoa.ensembl.org

During summer, two more sites – for Fungi and Plants – should be made available.

Since some WP release, the comment author’s link in comments is broken – it has ‘ external nofollow’ attached straight to the href attribute (which breaks the link).

I assume that the problem is caused by Google Analytics, namely the “track outgoing clicks” feature (as recalled, might be inaccurate feature name). “Track outgoing links” adds some JavaScript code to all outgoing links, and that script has tick characters like this one ‘ which, incidentally, are also used for delimiting the values of comment anchor tags.
