On this day in 1949, the EDSAC at Cambridge University ran its first programs!
It calculated a table of squares and a list of prime numbers, becoming the first practical general-purpose stored-program computer in regular service. The digital world started here.

youtu.be/DjhRRj6WYcs?... is an incredible introduction to things you may take for granted, including the job queue being a literal queue. Maurice Wilkes was still turning up to Computer Lab happy hours on Friday afternoons to have a beer well into his 90s. Fucking legend.

We were thrilled to welcome New Scientist to #TNMOC to film EDSAC. As project lead Andrew Herbert put it, "We're kind of doing archaeology" - piecing together how this pioneering machine operated in pursuit of a working rebuild.

もう随分と昔になってしまいましたが、世界初のプログラム内蔵式コンピューターであるEDSACについて書いた覚えがあります。 EDSACは教えないで
実はこのEDSAC、そのプログラムを入力するのに既に単なる数字の羅列ではなくてアセンブラの元祖でもある「イニシャルインプットルーチン」というプログラムを使って、実行させるプログラムの書かれている「紙テープ」を読み取るという仕組みが使われていました。...

Love this short film from @newscientist.com!
Really brings to life the early history of #computing, telling the story of the 1940s EDSAC computer & the @tnmoc.bsky.social project to rebuild a working replica. 👏
