CAP theorem In theoretical computer science, the CAP theorem, also known as Brewer's theorem, states that it is impossible for a distributed computer system to simultaneously provide all three of the following guarantees: In 2012 Brewer clarified some of his positions, including why the oft-used "two out of three" concept can be misleading or misapplied, and the different definition of consistency used in CAP relative to the one used in ACID. History The proof of the CAP theorem by Gilbert and Lynch is a bit narrower than that which Brewer had in mind. The theorem sets up a scenario in which a replicated service is presented with two conflicting requests arriving at distinct locations at a time when a link between them is failed. The obligation to provide availability despite partitioning failures leads the services to respond; at least one of these responses shall necessarily be inconsistent with what a service implementing a true one-copy replication semantic would have done.

Elements of a Strong Business Plan Napkin Think Force yourself to summarize your idea on the back of a cocktail napkin. Don’t submit your plan until you have this level of clarity. Our brains make the social graph real Brilliant web essayist Maciej Cegłowski of Two Steaks and Pinboard fame has focused his considerable insight on the area of web standards I've been involved with for the past few years. You should go and read his The Social Graph is Neither now. Maciej is spot on in his criticisms: This obsession with modeling has led us into a social version of the Uncanny Valley, that weird phenomenon from computer graphics where the more faithfully you try to represent something human, the creepier it becomes. As the model becomes more expressive, we really start to notice the places where it fails.Personally, I think finding an adequate data model for the totality of interpersonal connections is an AI-hard problem. But even if you disagree, it's clear that a plain old graph is not going to cut it.
ShiftWindow Note to EVE Online players, I recommend you use EVE Launcher instead of ShiftWindow, it has been tailored specifically to your needs. I wrote ShiftWindow when I got annoyed at the otherwise excellent EVE Online. It crashed most out of the times I tried switching tasks, using alt+tab. The first version of ShiftWindow could do little more that find the EVE window and then move and resize it. The game worked perfectly in windowed mode, but most players like the look of the game in full screen view better.
