I am working on a complete rewrite of my PictPress plugin for WordPress. PictPress is intended for a way of working where you upload images to your website outside the WordPress admin user interface, e.g. via ftp, shared directories, etc. PictPress offers an easy way of including these images in a new post.

It just came to my attention that PictPress 0.91 has a vulnerability for website attacks caused by an unvalidated argument to the resize.php script. As far as I know this vulnerability has been fixed from version 0.99 upwards. All users of the older version should upgrade or remove the plugin from their website.
If there are still vulnerabilities in the newer versions, please let me know.
I did an upgrade yesterday, and this did not go smoothly, Leopard bit me hard:

After upgrading to an Intel iMac, my HP Deskjet 840C started to produce garbled output. Fonts were too large and clipped at the bottom. Apparently the HP Deskjet 3.3 driver is broken on Intel computers. Solution is to download and install the HP Deskjet 2.7.1 driver. This is a PPC driver and will work via Rosetta, but output looks good.
New and old iMac side by side.

If I were a Springer-Verlag Graduate Text in Mathematics, I would be J.L. Doob’s Measure Theory. I am different from other books on measure theory in that I accept probability theory as an essential part of measure theory. This means that many examples are taken from probability; that probabilistic concepts such as independence, Markov processes, and conditional expectations are integrated into me rather than being relegated to an appendix; that more attention is paid to the role of algebras than is customary; and that the metric defining the distance between sets as the measure of their symmetric difference is exploited more than is customary.

Often sites display larger images split up in tiles of e.g. 256×256 pixels. The tiles can easily be retrieved using e.g. curl. The full image can be reconstructed using ImageMagick montage:
montage +frame +shadow +label -tile NxM -geometry +0+0 *.jpg joined.jpg
where N is the number of horizontal tiles and M is the number of vertical tiles.

The white point is the colour value of pure white in a colour management system. Two different white points are involved:
A colour management system (CMS) transforms colours from an input source to an output destination. The colours from input source are characterised by an input profile, the colours on the output destination are characterised by an output profile. Additionally a rendering intent must be specified to control aspects of the transformation. A standard for colour profiles has been produced by the International Colour Consortium (ICC).
