For Togelius, research differs from tinkering by scholarship (putting your work into the context of previous work), testing (studying and describing how it works), goals (being an attempt to solve an important problem, although this definition is unfortunately somewhat circular), and persistence (“carry[ing] out sustained efforts over a long time, where individual experiments and papers are part of the puzzle”).
Abu Zubaydah was subjected to #torture 83 times in one month, has lost his left eye in #CIA custody, and is still in solitary confinement, but is apparently innocent.
Not only is there an argument that #video-games are essential for #AI, but also a prototyping language for 2D sprite games called VGDL, kind of like ZZT in a way.
The prototyping language for 2D sprite #video-games called VGDL is explained in this chapter of the #ebook “Artificial and Computational Intelligence in Games”. 2013, cc-by.
The reason for the EU: “no army has crossed the Rhine river in more than 70 years, and this is the longest period of peace on the Rhine since before the rise of the Roman Empire”. #history
Charlie Stross thinks #Apple’s future includes “a global secure payments infrastructure that takes over the role of Visa and Mastercard’s networks”, then retail banking.
the Zork #Z-machine #virtual-machine #ISA architecture had JSish property lists (albeit with 5-bit property IDs) for the objects (“Things”) in the game, which were organized into a rigid but mutable containment tree; they were mutable and not pageable, but program code was immutable and consequently pageable.
part of the latest version of the Zork #Z-machine #virtual-machine spec. Interesting to note that they’re scaling string and routine addresses by 4 or 8 (thus imposing alignment constraints!) in order to make the best of their 16-bit addresses.
Interesting, Infocom tried to use the #Z-machine #virtual-machine as a database engine called Cornerstone. #history
Seems like the #Z-machine #virtual-machine requires savegames to be in a different format from story files (programs), because the story files can’t include a suspended call stack, and savegames must.
The mysterious famous hacker #Rossum has unmasked himself: he is named Peter Barrett, holds 110 patents, developed Cinepak (the first widely used video codec), co-founded Rocket Science Games, was CTO of WebTV at Microsoft for 13 years, and is now CTO at Andy Rubin’s hardware venture fund, #Playground.
#Oleg and Chung-Chieh Shan came up with a new way of describing #Hindley-Milner type checking: as abstract interpretation with non-standard semantics, I think. #ccshan
