With an introductory talk by Georgiy Treyvus

"In late July of 2018 I dealt with what may have been the most catastrophic technical disaster I've ever found myself in and by the skin of my teeth managed to come out on top. This talk is about a series of events almost too insane to be believed. This is the story of how I made a new OpenPGP keypair, got my public key signed by Richard Stallman himself, deleted my only copy of the private key the next day, and then used what amounted to crude forensics techniques to successfully recover the deleted key material four days later. I'll discuss how I got myself into this mess, how I got myself out, alternative approaches I feel in retrospect could've been somewhat easier, and shocking bugs in GnuPG. Lulz and facepalm moments galore..."

Hans Hübner talk on A CLtL1 implementation for VAX/VMS

The VAX is a classic computer architecture from the 1970ies, and as it was in wide spread use until Intel took over the world, there were a number of LISP implementations for it. VAX LISP was the offering from Digital Equipment, the producer of the VAX, and being a long term VAX fan boy, I had to give it a good workout when I finally got my hands on it. Join me for a short excursion into the past, when compilers were licensed as binary and before Common Lisp became the contender of Smalltalk, C++ and Java - And it lost.
