JefRaskin.com

This is the official site about Jef Raskin, author of The Humane Interface (Addison-Wesley 2000), creator of Apple's Macintosh, the Canon Cat, click-and-drag selection and other inventions. He coined the term and the concept of "information appliances." This site contains works by and about him, including Jef's writings on a variety of subjects. There is also a tediously long curriculum vitae. Lots of dates and references if you need them. Otherwise, skip it.

This site also contains pointers to a current project to implement many of the features and methods described in Jef's recent book. The project, a part of the new Raskin Center for Humane Interfaces, is called "Archy" and will be available for download later this year. This site was designed and is maintained by Galen Panger and Aza Raskin.

What were Einstein and Gödel talking about?

Egy erdekes cikk a The New Yorker-ben amibol peldaul kiderul, hogy Einsteinnek megtiltota a Sved Akademia, hogy a Nobel dij atvetelekor a relativitaselmeleterol beszeljen, mert azt nem ismertek el, igy o inkabb Stockholm helyett Goteborgban tartotta koszonobeszedet, ahol a relativitas irant erdeklodo V. Gustav kiraly az elso sorban ulve hallgatta.

Azt is megtudhatjuk, hogy Godel olyan alaposan felkeszult az alkotmanybol a amerikai allampolgarsagi tesztjere, hogy az ertekelo hivatalnoknak be akarta bizonyitani, hogy az alkotmanyukban levo kovetkezetlenseg lehetove teszi egy diktator felemelkedeset. A szobaban Einsetein es Oskar Morgenstern fogtak vissza, nehogy kitoloncolas legyen a vege.

Az is kiderul, hogy nem csak a fiatalsaguk volt tele nehezseggel, de utolso eveikre ismet bekemenyedett az eletuk.
