CodeIgniter from Scratch: Searching Data without Query Strings

A Nettuts+ video by Burak Guzel on a subject area that I have been working on recently.  I found the video interesting and it contains lots of ideas that I could use, but I have a couple of points:

• Keeping query strings in the database doesn't look all that scalable.  You are committed to keeping every query string ever used, forever, if you want your URI's to be permanent.
• The set of movies on a given page will change if movies can be added or deleted from the database, so your URIs will not permanently specify a particular page of movies.  This problem also applies to most pagination systems, I think.

Still, the video is very good, as is the whole CodeIgniter from Scratch series, and I would recommend them to anyone interested in CodeIgniter.

Pink and White Fungus

A fungus, probably Cylindrobasidium evolvens (= Cylindrobasidium laeve).

A month later, at the other end of the Wilderness, I came across the following which is probably the same species at another stage of development.

Six-Spot Burnet Moth

From last summer: a newly-emerged six-spot burnet moth, Zygaena filipendulae (Lepidoptera: Zygaenidae) clinging to a grass stalk.  I could tell the moth was newly-emerged because just a few centimetres further down the stalk was the pupa case it had emerged from:

Crust Fungus

A toothed crust fungus, probably Basidioradulum radula.

Moth

From last summer: a small grey-brown moth with a metallic sheen, probably  a Coleophorid moth (Lepidoptera: Coleophoridae). 

Initially had this down as a possible Glyphipterix fuscoviridella but the forked wings are not right for Glyphipterix sp.  Then I thought it might be Metriotes lutarea but that flies in May and the above moth was seen in July.
