Patch your devi... oh, hang on a sec Gareth Corfield Tue 11 May 2021 // 09:15 UTC Share Copy A computer science professor from Sweden has discovered an arbitrary code execution vuln in the Universal Turing Machine, one of the earliest computer designs in history – though he admits it has "no real-world implications". In a paper published on academic repository ArXiv, Pontus Johnson, a professor at the KTH Royal Institute of Technology in Stockholm, Sweden, cheerfully explained that his findings wouldn't be exploitable in a real-world scenario because it pertained spe...

LESSWRONG 88 ( Originally posted in December 2015: A dialogue between Ashley, a computer scientist who's never heard of i.  Unbounded analysis BLAINE:  Good evening, Msr. Ashley. ASHLEY:  I've heard there's this thing called "Solomonoff's theory of inductive inference". BLAINE:  The rumors have spread, then. ASHLEY:  Yeah, so, what the heck is that about? BLAINE:  Invented in the 1960s by the mathematician Ray Solomonoff, the key idea in Solomonoff induction is to do sequence prediction by using Bayesian updating on a prior composed of a mixture of all computable probability distributi...

Homo informaticus Luc de Brabandere lets us sail with him along the two great rivers of thought that have flowed down the centuries from ancient philosophy into modern computer science, from Plato and Aristotle to Alan Turing and Claude Shannon. The history of computer science did not begin eighty years ago with the creation of the first electronic computer. To program a computer to process information – or in other words, to simulate thought – we need to be able to understand, dismantle and disassemble thoughts. In IT-speak, in order to encrypt a thought, we must first be able to decrypt...
