The Electronic Components and Semiconductor Superstore Self-Assembly Lab Berkeley Logo (UCBLogo) The current version is 6.0, posted 14 Sep 2008. 6 Jan 2009: The bug in the version for PowerPC-based Macs that required X11 to run Logo has been fixed. Re-download UCBLogo if you had that problem. Here are links to version 5.3 for frozen platforms DOS (or by HTTP), or Mac pre-OS X (or by HTTP). If you downloaded 6.0 before Tues 9/30/2008, 10:30pm PST, and it didn't run on your PowerPC-based Mac, download it again -- that's been fixed. Also consider David Costanzo's FMSLogo, an updated version of George Mills' MSWLogo, a multimedia-enhanced version for MS Windows based on Berkeley Logo. Here are links to other versions of Logo. If you got here by Googling "logo" and are looking for someone to design a logotype (an identifying symbol) for your organization, you're in the wrong place. Now FREE for personal use: The second edition of Computer Science Logo Style, a three-volume series intended mainly for teenagers and their teachers, or for adults who aren't professional programmers.
Le projet Thymio II est une évolution du robot Thymio, les deux développés dans le cadre d'une collaboration entre l'Ecole Polytechnique Fédérale de Lausanne (EPFL groupe MOBOTS) et l'École Cantonale d'Art de Lausanne (écal). Pour Thymio II, le développement a été réalisé dans le cadre du programme NCCR Robotics et l'association Mobsya a contribué au développement et gère sa production. L'objectif du projet Thymio II est de permettre au grand public d'accéder à la robotique par un robot programmable et riche en possibilités, afin de permettre l'exploration des technologies liées à la robotique. Accessoirement cet objectif peut s'appliquer de façon plus spécifique aux écoles, avec l'utilisation de la robotique comme outil pédagogique. Pour atteindre cet objectif nous avons choisi un mode de diffusion très spécifique: Tout ceci nous permet de diffuser le robot Thymio II à prix minimal, basé sur des marges bien plus basses que ce qui est pratiqué dans le commerce.
Comment: The downside of being competent | SBS News The phrase “shit hits the fan” has uncertain origins. Some claim it’s a descendant of a World War II adage “the garbage hit the fan.” As the Online Etymology Dictionary has it, it derives from an old poop joke. In any case, people have probably heard the phrase in reference to something gone awry at work or in life. And too bad for that person. To begin, the researchers began by establishing that people do, in fact, assign more tasks to those they perceived as more competent. “People ask high self-control people to do more for perfectly logical reasons—because they think that those who successfully demonstrate high (vs. low) self-control will perform better and accomplish more. A separate experiment found that participants not only assigned more tasks to the go-getters—but underestimated how much work it would take to get the job done. The researchers then tried to understand how these expectations play out in real life. This article was originally published on The Atlantic.

Which Board is Right for Me? For a few months after Raspberry Pi came out, the choice was pretty simple. If you wanted to talk to arbitrary electronics, your best bet was to buy an Arduino microcontroller board; if you needed the power of an ARM-based processor to run Linux, the Raspberry Pi single-board computer (SBC) was the obvious choice (that is, if you could get your hands on one. Delivery issues are mostly resolved, but last year some people waited more than six months for their Pi). Before Arduino and Raspberry Pi, things were more complicated. Going forward, things aren’t just complicated again — they’re bewildering. We’re now seeing an explosion of new boards coming to market, and there’s no reason to expect the trend to slow in the next year or two. Life Before Arduino The commercial microcontroller story starts, arguably, in 1971, with the arrival of the 4-bit Intel 4004. Still available off-the-shelf today at less than $2 a chip, the PIC is a workhorse. The March of Arduino The Tessel The LaunchPad MSP430
Animal Architecture: Buckminster Fuller's Tensegrity In 1932 R. Buckminster Fuller famously philosophized: "Don't fight forces. Use them!" (Fuller, Shelter). A man of many trades -- architect, author, designer, futurist, inventor, and the second president of Mensa -- he applied this mantra throughout many aspects of his work. In particular, it is more or less the backbone of his studies of and theories on synergetics, an interdisciplinary science that explores the formation and self-organization of patterns in systems. Fuller originally coined the term tensegrity, a portmanteau of tensional integrity, while studying "energetic-synergetic geometry" during World War II. Tensegrity describes a structural-relationship principle in which structural shape is guaranteed by the finitely closed, comprehensively continuous, tensional behaviors of the system and not by the discontinuous and exclusively local compressional member behaviors. Tensegrity structures fall into two main categories -- prestressed and geodesic. Works Cited Bowers. Vondrejs.
