Dr. Bunsen / Time Warp
I use it to modify Time Machine’s backup behavior using weighted reservoir sampling. I built Time Warp to preserve important backup snapshots and prevent Time Machine from deleting them.

Flower Filter
'A simple time-decaying approximate membership filter' -- like a Bloom filter with time decay. See also http://eng.42go.com/flower-filter-an-update/ for some notes on the non-independence of survival probabilities, and how that imposes negligible differences in practice.

Atelier olschinsky - "Cities III 05"
Fine Art Print on Hahnemuehle Photo Rag Bright White, 310g: 40x50cm up to 70x100cm. Some great art based on decayed urban landscape shots, from a Vienna-based design studio.

Exponentially decaying lists
'log scale for lists; Decaying lists allow to manage large range of values. A decaying list grows logarithmically with the number of items. It follows that some items are dropped when other are inserted.' (via Tony Finch)
