Professional Quality CAD on Linux with DraftSight

Many computer-aided design (CAD) users in the Linux community were thrilled recently with the beta release of DraftSight, a freeware (meaning zero-cost-but-proprietary) CAD package for Linux, Windows, and Mac OS X. DraftSight's creator, Dassault Systèmes, is a well-known CAD shop most famous for its Windows product SolidWorks. Although this new app is not open source, it is the first professional-level package available for free on Linux that can read and write the industry-standard .DWG file format. Free software CAD still has a long way to go, but for now DraftSight offers Linux users a rare glimmer of hope.

US: Android is the most popular smartphone system

US market researcher comScore reports that 69.5 million US citizens own a smartphone, and that one third of these phones run Google's open source Android mobile operating system. On the popularity scale, RIM and Apple are next with 29% and 25% of users, leaving Microsoft (8%) and Palm (3%) far behind. According to market researcher Nielsen, the US sales figures for Android phones have already been above those for RIM and Apple since July 2010, but this is the first time that Android is also leading in terms of devices in use. comScore said that last November, RIM was in the lead with 34%, followed by Android and Apple with an almost identical share each of 25% of users.

Booting Bare Hardware

Booting a computer is always more complex than one wants to think. On the PC side, it looks as if BIOS finally is retired and replaced by EFI (I wonder which was the last OS to use BIOS for anything that just loading a secondary bootloader). On Mac, EFI has been around for a while. On embedded Linux systems, however, u-boot has been a big player for a long time.

Arduino Cookbook Review

The Arduino has become a white-hot topic these days by granting the ability to allow anyone with a computer, a 30-dollar Arduino, and an incentive to route electrons through sensors and actuators and make them do interesting things. The latest book to make it to this topical pile-on is technologist Michael Margolis' Arduino Cookbook. Does it have the essential recipes to satisfy the discerning palettes of Arduino enthusiasts? Read on to find out.

This week at LWN: Slackware 13.37: Linux for the fun of it

The SUSE family of distributions has the motto "have a lot of fun," but it's Slackware that really pushes that philosophy to its limit. While most of the major Linux distributions are shaped by corporate influence, community politics, and pursuit of mainstream success, Patrick Volkerding has taken a much different path with Slackware, which is readily apparent in the release candidate of Slackware 13.37.

Google bid for a patent armoury

Google has placed a $900 million bid on Nortel's patent portfolio in an attempt to build a "formidable patent portfolio" to defend the company from other company's patent related law suits. The bid from Google has been selected by Nortel as the "stalking horse" bid making its $900M offer a starting point for other bidders. The company said that protecting the open source communities around Android and Chrome was one of the reasons it was bidding. Google is still a relatively young company and has not applied for that many patents.

Stopping Runaway Applications in Linux

With Linux comes great power — and great control. When you're running Linux, you have thousands of applications, utilities, and commands at your fingertips — and ultimate control over those applications as well. When they start, how they start, and (more importantly) how they stop. Let's take a look at some of the commands and utilities you have to master your Linux systems.

Could Google's vendor crackdown backfire?

Google's reported decision to more tightly police its Android platform could improve overall quality, but runs the risk of losing vendors to Microsoft's Windows Phone 7, say analysts. Meanwhile, despite the release of the iPhone 4 on Verizon, Android kept building U.S. market share in February, growing to a leading 33 percent, says ComScore.

7 Ways of Staying Backed Up on Ubuntu Linux

You’ve installed a multitude of packages on your heavily customized Ubuntu desktop. Games, themes, and tweaks, it’s got it all. Plus, you’ve got your whole music and movies collection meticulously organized. With a wide relaxed grin you bask in the glory of your new-found productivity so much that you’re already thinking of penning a self-help book. Meanwhile, as you are lost in that reverie, a 3-eyed monster suddenly appears out of nowhere, snatches your laptop and gobbles it up! OK, I might be exaggerating, but the fact is, we can never be 100 percent sure of our data.

Have Some Cheese with that Webcam

Since the launch of Linux Magazine TV (LMTV) in February of this year, my interest in video has increased beyond any reasonable limits. I’m obsessed with video and our efforts in this new area for us. For weeks I’ve tried to find a way to use my new Panasonic HM-TA1 pocket video camera for new LMTV entries and my own projects. Last week I discovered Cheese Webcam Booth (Cheese), which is the topic of this week’s article. Using Cheese is intuitive and closely resembles the Apple iPad2 Photo Booth app. The difference in price between Cheese (free) and Photo Booth ($499+ for the iPad2) is significant, which definitely gives you something to smile about.

Why I was wrong about Microsoft

Although as a cynical journalist I was obliged to be sceptical, I did begin to feel that there were grounds for optimism when it came to Microsoft's evolving attitude toward open source.

Alas, I was wrong.

Problems Linux Enthusiasts Refuse to Address

Despite the many successes seen from the desktop Linux camp over the years, there are some areas that continue to be left largely unchecked. Rather than automatically painting my findings with a negative brush, instead let's examine each issue closely.

Fedora 16 Might Be A Beefy Miracle

Ubuntu 11.10 is codenamed the Oneiric Ocelot, which is perhaps the most unique Ubuntu codename to date, but going up against Mark Shuttleworth's next distribution update will be Fedora 16. What's the codename for that next Red Hat release? It might be called a Beefy Miracle...
