K2G2 -- a wiki for "krafty knerds and geek girls" -- has a marvellous series of posts about "Computational Craft" through which traditional crafting practices, like knitting, are analyzed through the lens of computer science. The most recent post, A Computational Model of Knitting, point out the amazing parallels between knitting and computing, with knitting needles performing stack and dequeue operations, "While straight needles with caps store and retrieve their stitches according to the principle of LIFO (first in - last out), double pointed and circular needles additionally implement the functions of a queue or FIFO (first in – first out), effectively forming a double ended queue, also known as dequeue."
There even is an automatic garbage collection accounting for dropped stitches: once the number of superordinate stitches referencing a stitch drops to zero, the whole stitch is dropped altogether, meaning that it is replaced by the null stitch, which only contains references to is neighbors but not to any subordinate stitch. This garbage collection mechanism gives rise to typical avalanche effects, generally known as runs or ladders.

Studio North was commissioned to refit an old elevator shaft in a converted warehouse loft in Calgary; they built a tall, narrow library with climbable shelves whose hand- and foot-holds retract into the shelving.
Libretaxi is an open source project that lets anyone become a rideshare driver in less than a minute; it has more than 20,000 users worldwide, and is maintained by Roman Pushkin, who started the project in December 2016 and is now planning to quit his job and work on it full time.
Mister Alphabet is an action-figure designed to cleverly bend and contort into every letter of the Latin alphabet; the website is long on trademark warnings and arty Instagram photos, but short on details, like, “Is this an object of commerce?” and “If so, where does one buy it?” (via Kottke)
You know the drill. You go to the dentist and they ask you how often you floss. You lie through your teeth and say, “every day!” (Bonus points if you have some cilantro or chives stuck in your gums from lunch). You don’t want to keep up the charade any longer, but rubbing that tiny strand […]
The Raspberry Pi Foundation has done outstanding work packing a fully capable desktop computer into a package the size of a deck cards—especially one that only costs $35. But if you already have a working laptop, why should you care? Oh, how much you have to learn. Besides operating well as a compact digital media hub, […]
Custom coffee vessels are the perfect piece of office flair, but it’s just a matter of time before your VOTE FOR PEDRO mug will start to lose its relevant wit. Why not have a new one every day, with whatever silly nonsense you want sticking off the sides? You can save big on your novelty […]
