You can now use quotes in you postings in my guestbook! And if you write something like http://mgeisler.net/ or [email protected] it will automatically be turned into real links. (This isn’t my guestbook, so there are no links here :-)

All this magic is done with regular expressions (regexp). You can take a look at the source of the page if you want to see the expressions themselves. But beware, they are pretty complicated. Maybe I should write a small tutorial on regexps.

Take a look at my new guestbook. Here you have the chance of telling me and others what you think of gimpster.com. Until I make a tool for deleting your posts, the word is all yours :-)

Just remember that you can’t use any quotes. Both single-quotes (’) and double-quotes (”) will be escaped. Also, any HTMl-tags other that <b>, <i> and <a> will be stripped.

I’ve just updated my tutorial on PHP. I tried to explain some parts better, and made a proper ending.

My 21″ Philips monitor, a 201P10 Brilliance, has just arrived. Wow — I expected it to be big, but not this big! It comes in a box, which measures roughly 1 meter (3 feet) at all sides. My dad and I could barely get it through the door into my room :-)

First thing to do after placing it onto my desk was to see how everything looked at a resolution of 1600×1200. It simply looks perfect. It can be used at resolutions as high as 2048×1536. I tried this under Windows, thanks to my Matrox G400. I could run it as high as 67 Hz, but at this extreme resolution everything is kind of small. Now I run it at 1600×1200, which is the ideal resolution for this monitor. It has a horizontal aperture-grill width of 0.24 mm (0.00945″) and display-area is 16″ wide, which means that is can resolve up to 16″/(0.00945″/pixel) = 1693 pixels. And it can handle a vertical refresh-rate of up to 97Hz in this resolution.

The on-screen-display is functional and contains many settings. You can adjust the purity in the corners individually. If the top left corner has a slight red tint, you can adjust it so it is pure white. You can also adjust both the vertical and horizontal convergence. The convergence is the alignment of the three electron-beams (one for each of the three primary colors: red, green and blue), so if you have a checkerboard-pattern, and all the black tiles is a little blue on side, it means that the three beams isn’t aligned probably. Finally you can adjust for moiré.

All in all, I would say that I’m very impressed by this monitor. After trying a 21″ monitor, you’ll never want to go back to a 17″.

I’ve just made some fine error-documents for my site. This means that if the server can’t find the document you ask for, you’ll get an “nice” error-message instead of the standard from Apache.
