Hash blogs

Hash is a prominent term in computing and cryptography, according to the OED, “so called because it consists of small pieces of code arranged in an apparently jumbled and fragmented way.” See posts tagged hash.

To hash is to chop up, to hack, a term applied readily to food (recooked and chopped meat), narcotic dried herbs (hashish — in Arabic). Through further linguistic coincidence the word resonates with software hacking as applied drudgery and routine work, low-paid piecework, and labour delivered on-demand in the gig economy.

Technically, some of these associations are “false cognates.” According to the Online Etymological Dictionary, “hack” applied to labour derives from the pastureland in Hackney, England, where horses were kept for hire (https://www.etymonline.com/search?q=hack). So it’s not actually about chopped up work tasks, or hashing.

If I were to make a hash of this blog post I would turn it into a jumbled mess. To hash is to arrange, re-arrange or jumble elements in such a way that they are unrecognisable from the original arrangement.

Hash house

A hash house was a type of cheap eatery in Malaysia, so named as they served chopped up meaty leftovers (hash). Ex-patriot brits would meet there and play fake hunting games. The Hash House Harriers (HHH) were ex-pats who developed the practice of running in simulated hare and hounds orienteering events. The “hare” would lay down markers in flour along a route and others would follow. You can see the HHH’s standard waymarking symbols online, and the association is explained at www.hashhouseharriers.com.


Hash is not a term used in architecture, but collage is. In architecture, art and urbanism the concept of the hash most likely invokes concepts of collage, the deliberate or accidental arrangement of disparate elements to stimulate something new. According to architectural writer Jennifer Shields,

“A collage as a work of art consists of the assembly of various fragments of  materials,  combined  in  such  a  way  that  the  composition  has  a  new  meaning,  not  inherent  in  any  of  the  individual  fragments” (2).

So, there are a few connections with urban life: digital infrastructures that rely on hash tables, hash lookup, security codes, blockchain, etc; something about urban games, colonial legacies, and waymarking, and the arrangement and incongruous juxtaposition of urban elements as collage.

  1. Asad Khan says:

    But also the word ‘assassin’ has root in hashshāshīn, ‘hashish smoker’––relevance to all sort of stealth, dissimulation and precision. Hashishtecture would then be a kind of lethal architecture, that is, the very medium of assassination. Something that evades remote-sensing signals, cloud maps, including all the sensing technologies of the smart city, camouflaged and hibernating?

    1. Fancy you knowing that! Thanks for the tip … and the warning.
