FreeCAD 3D CAD modeler

FreeCAD is a general purpose feature-based, parametric 3D modeler for CAD, MCAD, CAx, CAE and PLM, aimed directly at mechanical engineering and product design but also fits a wider range of uses in engineering, such as architecture or other engineering specialties. It is 100% Open Source and extremely modular, allowing for very advanced extension and customization.

FreeCAD is based on OpenCasCade, a powerful geometry kernel, features an Open Inventor-compliant 3D scene representation model provided by the Coin 3D library, and a broad Python API. The interface is built with Qt. FreeCAD runs exactly the same way on Windows, Mac OSX and Linux platforms.

FreeNAS 8.3.1

Josh Paetzel has announced the release of FreeNAS 8.3.1, an open-source storage platform that supports sharing across Windows, Apple, and UNIX-like systems: "The FreeNAS development team is pleased to announce the immediate availability of FreeNAS 8.3.1-RELEASE. FreeNAS 8.3.1 is based on FreeBSD 8.3 with version 28 of the ZFS file system, and features volume based encryption for ZFS. There have been no major changes between 8.3.1-RC1 and RELEASE, mostly bug fixes and minor usability improvements to the GUI. Please familiarize yourself extensively with the encryption features of FreeNAS before using them. Doing the wrong thing can end up in a state where the volume is hidden behind very difficult-to-break AES 256 encryption. Many modern CPUs feature hardware support for encryption. If hardware support is available FreeNAS will use it.

The Difference of SU AND ROOT


There have been many questions about, what is the difference between “su” and “root” . . well, the difference is minimal but still very important.

As you login as “root” right from booting the system, all the privileges are set to root, what makes your system more vulnerable to your own mistakes and those wishing to enter your system.
As you login as normal user, the privileges are limited, thus it´s safer. To be able to do administrative tasks you can temporally login as root using “su” in a console/terminal, that way the root privileges are limited to the actions you do in the console. So the rest of the system is still in “normal user” mode, and this makes it safer.
We do use the same password for “su” and “root”, but once you are logged in as normal user, typing “root” in terminal will only give you “bash: root: command not found”.
