(tech) Free CAD open source

FreeCAD is a general purpose 3D CAD modeler. The development is completely Open Source (GPL & LGPL License). FreeCAD is aimed directly at mechanical engineering and product design but also fits in a wider range of uses around engineering, such as architecture or other engineering specialties.

FreeCAD features tools similar to Catia, SolidWorks or Solid Edge, and therefore also falls into the category of MCAD, PLM, CAx and CAE. It will be a feature based parametric modeler with a modular software architecture which makes it easy to provide additional functionality without modifying the core system.

 source: http://sourceforge.net

As with many modern 3D CAD modelers it has many 2D components in order to sketch 2D shapes or extract design detail from the 3D model to create 2D production drawings, but direct 2D drawing (like AutoCAD LT) is not the focus, neither are animation or organic shapes (like Maya, 3ds Max, Blender or Cinema 4D), although, thanks to its wide adaptability, FreeCAD might become useful in a much broader area than its current focus.

Another major concern of FreeCAD is to make heavy use of all the great open-source libraries that exist out there in the field of Scientific Computing. Among them are OpenCascade, a powerful CAD kernel, Coin3D, an incarnation of OpenInventor, Qt, the world-famous UI framework, and Python, one of the best scripting languages available. FreeCAD itself can also be used as a library by other programs.

FreeCAD is also fully multi-platform, and currently runs flawlessly on Windows and Linux/Unix and Mac OSX systems, with the exact same look and functionality on all platforms.

For more about FreeCAD's capabilities, take a look at the Feature list, the latest release notes or the Getting started articles, or head directly to the User hub!

The challenges and opportunities of Social Media

Blogs, which represent the earliest form of Social Media, are special types of websites that usually display date-stamped entries in reverse chronological order (OECD, 2007). They are the Social Media equivalent of personal web pages and can come in a multitude of different variations, from personal diaries describing the author's life to summaries of all relevant information in one specific content area. 

Blogs are usually managed by one person only, but provide the possibility of interaction with others through the addition of comments. Due to their historical roots, text-based blogs are still by far the most common. Nevertheless, blogs have also begun to take different media formats. For example, San Francisco-based Justin.tv allows users to create personalized television channels via which they can broadcast images from their webcam in real time to other users. 

Many companies are already using blogs to update employees, customers, and shareholders on developments they consider to be important. Jonathan Schwartz, CEO of Sun Micro-systems, maintains a personal blog to improve the transparency of his company; so does automotive giant General Motors. Yet, as is the case with collaborative projects, blogs do not come without risks. These generally present in two fashions. 

First, customers who—for one reason or another—turn out to be dissatisfied with or disappointed by the company's offerings may decide to engage in virtual complaints in the form of protest websites or blogs (Ward & Ostrom, 2006), which results in the availability of potentially damaging information in online space. Second, once firms encourage employees to be active on blogs, they may need to live with the consequences of staff members writing negatively about the firm. 

Microsoft's former “technical evangelist” Robert Scoble, for example, had a tendency to fiercely criticize the products of his employer—before he decided to leave the Redmond-based software company in 2006.

Library Supporting Research Communities in Developing Countries

 

In developing countries, libraries are often a hub of activity not only for information resources and services, but also for building foundational skills and knowledge within various user groups. With funding from an Elsevier Foundation grant, the Learning Resource Center (LRC) at Thai Nguyen University was able to substantially boost Vietnamese scholarship and scientific, technical and medical information exchange for scholars in Thai Nguyen Province and the north mountainous area of Vietnam.

The $40,000 grant, which began in April 2010, allowed the LRC to introduce hands-on training and mentoring programs, host interactive workshops, and publish a 150-page local language handbook on improving scientific writing and publishing. It also funded the implementation of an institutional repository using DSpace, open source software that enables sharing of content. 

Many American and Vietnamese LIS experts participated in the project. The two senior advisors - Patrick McGlamery, retired Director of Library Information Technology, University of Connecticut, and Terry Plum, Assistant Dean for Technology and GSLIS West program, Simmons Graduate School of Library and Information Science - took a holistic approach, advising information technologists, administrators, librarians and researchers on how to work together to boost scholarly publishing and sharing.

(info) Para saintis berebut mahukan otak Einstein!

Apakah yang terjadi jika seseorang yang genius telah meninggal dunia? Pastinya otak si genius dijadikan bahan ujikaji oleh saintis yang lain. Lanjutkan pembacaan di bawah ini;

Setelah lebih separuh abad meninggal dunia, otak saintis genius fizik yang terkenal dengan Teori Relativiti Umum, Teori Relativiti Khas dan Kesan Fotoelektrik yang membolehkan beliau menerima Hadiah Nobel Fizik pada tahun 1921 telah dipamerkan di Muzium dan Perpustakaan Sejarah Perubatan Mutter di Philadelphia, Amerika Syarikat (AS) tahun lalu.

Anna Dhody, kurator muzium tersebut menyatakan dalam satu temubual Yahoo!News bahawa pengunjung akan dapat melihat 45 keratan otak Einstein. Keratan berkenaan telah didermakan oleh pakar neuropatologi kanan Hospital Kanak-Kanak Philadelphia AS, Dr. Lucy Rorke-Adams. 

Salah satu keratan tersebut telah diperbesarkan di bawah bawah mikroskop khas untuk tatapan pengunjung pameran tersebut.

Anna Dorby berharap melalui pameran itu ia dapat mendorong ramai pengunjung dan peminat sains mengkaji tentang sains dan fisiologi otak. Sejumlah 45 bahagian otak Einstein itu telah melalui perjalanan yang sangat unik. Ia bermula dari kematian saintis tersohor itu pada tahun 1955 akibat abdominal aneurism dan otaknya diambil tujuh jam selepas kematiannya.

Thomas Harvey seorang ahli patologi telah mengambil otak tersebut sebagai satu spesimen untuk uji kaji autopsi yang dijalankan. Bagaimanapun pengambilan otak Einstein telah menimbulkan kontroversi sama ada ia mendapat izin waris. 

Dalam biografinya yang ditulis oleh Ronald Clark (1971) dikatakan: "Einstein sangat setuju jika otaknya dipakai sebagai objek penyelidikan dan meminta agar badannya juga diawetkan jika perlu".
