Prof. Leonard Kleinrock pioneered the application of queuing theory to modelling message switching networks in his (Ph.D. thesis and) book, "Communication Nets: Stochastic Message Flow and Delay". This was based on a simulation program which he wrote on the MIT Lincoln Laboratory TX-2 computer.

Humble Book Bundle: Martha Wells' Murderbot and More by TOR Fall in love with Martha Wells’ The Murderbot Diaries seriesβ€”the engine behind the hit AppleTV adaptationβ€”and help support World Central Kitchen.

The humble bundles don't often overlap with my interests, but I have to say, I have a lot of affection for this series in particular.

In the UK, S&H stamps were pink because Green Shield Stamps beat S&H to the trademark.

Imitated in the UK as "Green Shield Stamps", widely adopted. In 1977, the UK chain Tesco stopped participating in the stamps to cut costs. Terry Leahy proposed a loyalty card at Tesco in 1993, but execs were nervous. Leahy was successful and so the modern data-mining-driven loyalty card was born.

I have a Saga 1 keyboard, it was a big improvement. I recently got mine refurbished by these folks: www.mutant-caterpillar.co.uk/shop/index.p...

Restoring it was a giant pain for them; Ian described the pain, but there's not enough space in a comment to quote his description of the, er, saga.
