The processors aren't inmune to the radiactivity. This it produces soft errors, that are errors in the signals of its circuits, produced by the noise that generates the radiation on it. The consequences of the radiation over the machines aren't so devastating as over the human, because in the worst case we can reboot the machine, but the things that could do the machines affected by radiation to the humans, it could be dangerous.

linked data - semantic web
Tim Berners Lee, inventor of the Web, from the beginning wanted that his invention was semantic forming a global data base of the human knowledge, in which the information could be consulted by all the world and understood by the machines, to generate new knowledge, answer questions and create artificial intelligences that could surpass the Turing Test. This idea begins to become true, but first have to overcome several difficulties that I'm going to expose next. Read the rest of "The problems of the semantic Web"

W3C WCAG logo
Surely that a lot of times you have found webs impossible of be read, due to the color combinations used.
For that reason I've programmed a script that can transform any webpage making it more accessible. If you drag and drop this link to the bookmarks or favorite bar of your browser, and you click on it, when you find a web with colors that doesn't allow read it clearly, the web will change their color with the colors of Computable minds and the accesibility will be better in the majority of cases. If you want that the script will be executed always in all the webs, you can install it, having activated the Firefox extension Grease monkey, or using Chrome, and clicking in this link.
