Cad for linux (clone or near AutoCad)

Autocad is not ported on Linux but some apps exist.

Computer-aided design (CAD) is the use of computer technology for the process of design and design-documentation. But are there any good free CAD apps for Linux? Strangely, that is one of the questions we often receive in our mail. We will try to list not just the free CAD apps here, but also the non-free ones that works well under Linux(in no particular order).

Bricscad is a CAD package developed by Bricsys, originally built using the IntelliCAD engine. We have featured Bricscad before in our featured listing of top commercial apps for Linux. Bricscad is among the few commercially supported CAD packages which runs on Linux. Bricscad is capable of most contemporary AutoCAD functionalities.

'Father of the Internet' Warns Web Freedom Is Under Attack

The Hill
(05/21/12) Andrew Feinberg

Governments around the world are trying to use intellectual property and cybersecurity issues to control the Internet, says Google vice president and chief Internet evangelist Vint Cerf. "Political structures ... are often scared by the possibility that the general public might figure out that they don't want them in power," Cerf says. He speculates that the International Telecommunications Union will likely become the global Internet cop, and expects the group to try to lock in mandatory intellectual property protections as a backdoor for easy Web surveillance. The public should view even good-faith efforts at Internet policymaking skeptically because balancing freedom and security "isn't something that government alone is going to figure out," Cerf says. He is concerned about the U.S. Cybersecurity and Intelligence Protection Act passed by the House, because it does not offer enough limits on how information about cyberthreats would be used. Still, Cerf expresses optimism that resourceful engineers will find a way around hostile government attempts to restrict access.
