Dell's Linux laptop has good hardware, decent toolkit

Plenty of specialized companies out there sell PCs with Linux, but Dell is one of the very few mainstream contenders to have done so over the years. After some spotty initial offerings, it's taken a different approach with its latest Linux PC. Rather than try to sell Linux hardware to the masses, which the company has said typically requires support, it's focusing instead on developers, a savvy group that tends to need less help.

That's the plan behind the $1,549 Dell XPS 13 Developer Edition, an ultrabook that was born via the company's “Project Sputnik” skunkworks initiative last year combining Ubuntu Linux 12.04 Long Term Support Precise Pangolin and the company's existing XPS 13 laptop.

What started out as a pilot project turned into a real commercial product last fall, and earlier this year it got a nice upgrade. We got our hands on one recently and put this latest model through its paces.

Visually, the Dell XPS 13 Developer Edition is a thing of beauty. It's thin, sleek, and lightweight, weighing in at just under 3 pounds. With a top cover precision-cut from a single block of aluminum, the silver-toned machine features a carbon-fiber composite base surrounded with a ring of matching anodized aluminum. A comfortable magnesium palm rest features soft-touch paint.

Powering the Linux ultrabook is a third-generation Intel Core i7 processor with Intel HD Graphics 4000, 8GB dual channel DDR3L RAM, and a 256GB SSD drive. That's a nice setup for the kinds of compute-intensive tasks developers spend much of their time on, including repeated cycles of coding, compiling, testing, and debugging.

Dell Inc.The XPS 13 Developer Edition we tested has a third-generation Intel Core i7 processor with Intel HD Graphics 4000, 8GB dual channel DDR3L RAM, and a 256GB SSD drive.

Developers will also often have many windows open, so the fact that this machine sports a full 8GB of RAM rather than the standard XPS 13's starting point of 4GB eases the burden by minimizing swapping to disk, thereby improving overall responsiveness.

The 13.3-inch edge-to-edge glossy display, meanwhile, is constructed from hardened Gorilla Glass and offers full High Definition WLED, 1080p resolution, and a full 178° viewing angle. So compact is the PC's design, however, that it actually feels a lot more like an 11-inch laptop in overall size.

The backlit, full-sized keyboard is another visually appealing element, though we found it a bit too light to the touch. That's personal preference, of course. Much more striking, though, was the fact that it featured a Windows superkey rather than an Ubuntu one.

While it's not a performance issue, the presence of a Windows-specific key on this device underscores the fact that this is still essentially Dell's standard XPS 13 with Ubuntu simply preinstalled. Developers wouldn't have any trouble doing that installation themselves, so we were alert to other distinguishing features that would set this device apart for this Linux-minded crowd.

One such feature is the XPS 13 Developer Edition's full year of included Dell ProSupport and onsite service after remote diagnostics. Also included on the device, meanwhile, are two USB 3.0 ports (one with PowerShare), a mini DisplayPort, and a headset jack. No mouse was included, so we added our own.

Like many Linux machines, this one featured a nice, snappy startup; it can boot from cold in as little as 13.5 seconds, Dell says.

We did encounter an issue by which the installer crashed the first time around, but on the second attempt it worked like a charm. WiFi connected on the first try, so we got to work installing some extras, including Chrome, GIMP, and Shutter for taking screenshots.

Katherine NoyesFeaturing the Unity desktop, Ubuntu 12.04 offers a user-friendly Linux experience.

We were both already familiar with Ubuntu and the Unity desktop, so that part was immediately comfortable. Since this machine is aimed at developers, however, we were particularly interested to see what developer tools were included. Those available upon startup were the Bazaar version control system, the IcedTea Web Control Panel, IcedTea Java Web Start, a printing configuration tool, and the UbuntuOne cloud service.

Handy for our review-writing purposes was that LibreOffice was installed and ready to go. Even more joy-inspiring was the absence of the vast array of OEM bloatware you'll typically find on most Windows machines.

We were surprised, however, to find no sign of two particular developer tools Dell has been talking about since the Sputnik project began. Namely, neither the cloud launcher nor the profile tool that have figured so prominently in the Developer Edition plans were evident on the laptop.

It turns out both are still essentially in alpha form and currently hosted on GitHub.

DellDell's widely anticipated cloud launcher and profile tool are not yet included on the XPS 13 Developer Edition.

Some initial work has been done on the profile tool, but Dell ended up taking a break to focus on launching the machine, it said. “We have just started up again,” the briefing notes explained.

The cloud launcher, meanwhile, “currently exists preinstalled as LXC + JuJu,” Dell noted. “We are working with OpsCode to create a Chef version as well.”

In the meantime, the XPS 13 Developer Edition comes with VirtualBox preinstalled as well as Juju, a transitional package for Ruby 1.8, Python, and more.

Is there a need for a machine aimed specifically at Linux developers? We're not so sure. Most developers are more than capable of stripping any machine of its original OS and installing what they want themselves.

That said, however, this is a decent start. With its i7 processor and 8GB of RAM, it's equipped to handle most of what developers will throw at it. In fact, the BIOS supports Intel-VT “bare-metal” hypervisor virtualization, lending itself to setting up virtual machine instances that run at near hardware spec performance levels, such as using Linux’s 64-bit kernel built-in KVM Type 1 hypervisor.

Typically programmers will set up their own “test beds” as virtual machines. Using Btrfs, for example, programmers can “snapshot” the virtual machine, make testing programmatic changes to the configuration, and if need be “roll-back” to the snapshot taken beforehand.

It was smart to go with a laptop here rather than a desktop, as developers tend to appreciate that extra flexibility. Some developers might not like the screen size, and the trade-off in weight of 2.99 lbs would probably not be the deciding factor in wanting one of these units. For anyone whose criteria included a larger display, this unit would drop off of the “short list.”

Meanwhile, Dell clearly knows that developers have their own unique preferences. The tool selection provided should be considered a starting point but not complete for any specific purpose. No two programmers have the same set of use cases and needs. Instead, what they look for are reliability and performance metrics. After all, many programmers write with operating-system-agnostic tools that can be used on any hardware platform.

The XPS 13 Developer Edition has competition: Lenovo’s ThinkPad, Apple’s MacBook Retina or Air, or Google's Chromebook Pixel. These machines aren't customized for Linux work, but they're technically superior in construction and software certification, and it's nothing for developers to strip what's there and install any operating system they want. It will be interesting, however, to revisit this device once it's fully loaded with all the developer tools Dell has planned.

Review: Linux Live USB Creator makes it easier to install Linux

There used to be a time when Microsoft Windows ruled the operating system world. But in recent years, the free and open source Linux operating system has taken a big bite out of Windows' dominance. But Linux has always had an image problem of seeming too difficult and unwieldy to install and learn, with a steep learning curve attached.

Linux Live USB Creator (LiLi for short) aims to take the sting out of a newcomer's introduction to the operating system by making it as easy as possible to get started. All you need is a USB stick with enough space—a minimum 2GB should do the trick—and five minutes of your time to install it. No user manual required.

After downloading and installing the software (developer Thibaut Lauziere also offers a portable version), open it up and you will see a simple straightforward user interface, showing the various steps needing to be completed. Once each step has been successfully carried out, the traffic light icon on the right hand side will turn green.

One option, after installation, is to run Linux inside Virtualbox which has the added benefit of being able to run two OS's at the same time (Windows & Linux)

First, you need to point the app towards the location of your USB stick in the computer.  Secondly, you need to choose the source of the Linux installation file. For example, you may have it already downloaded onto your computer. If so, point it towards that file.

If not, you can click "download" and a big drop-down menu of various Linux distros (and some non-Linux options) will be presented as possibilities.  Just choose the one you want to download.  For newcomers, it's probably easiest to choose Ubuntu as it's an easy Linux distro to get started with.

Once you've done this, the "persistence" level should be automatically at green. "Persistence" means that you can keep your preferences and data on your USB stick, after rebooting (normally this information is discarded).

Next come LiLi's personal options, which you must decide yourself. I enabled all three options but you need to decide for yourself what you prefer.

Finally, if everything looks OK, click the yellow lightning flash to begin the installation of your chosen Linux distro to your USB stick. In my case, it took only a few minutes and it was immediately ready to go.

There are two possibilities to run your new Linux distro. The first one is to reboot your computer and let Windows boot from the USB stick. However, this means you are running only Linux with no access to Windows. The second (and preferable) option is to go to the stick and choose "Virtualize This Key," which will launch the excellent VirtualBox software.

This is the software equivalent of a sandbox where you can run software programs inside, independent of the operating system you are currently using. In other words, you can be running Windows and at the same time, have Linux running inside the VirtualBox window.

The only downside to this option is that a huge amount of CPU is going to be required to run both OS's simultaneously. So you may notice things slowing down slightly as a result. If it gets too bad, try closing some non-essential programs.

In a word, Linux Live USB Creator should be on everyone's PC, as it is essential for everyone to learn that there is a world beyond what Microsoft has to offer. With it being portable, you can easily carry it about on a USB stick and introduce Linux to everyone you know.

Note: The Download button on the Product Information page takes you to the vendor's site, where you can download the latest version of the software.

It's been just a few weeks since the launch of Linux Mint 14 “Nadia,” but already the project behind the popular distribution has been making plans for its next release.

In fact, last week project lead Clement Lefebvre laid out a roadmap for Linux Mint 15, whose nickname is still to be decided.

Linux Mint has remained at the top of DistroWatch's page hit rankings for the past year or so, making its next version a topic of widespread interest.

Ready for a rundown? Here are three features we can expect to see in Linux Mint 15.

1. Cinnamon 1.8

It's already been a full year since the launch of the GNOME 2-like Cinnamon desktop environment, and the next version of Linux Mint will use Cinnamon 1.8.

Included along with that popular desktop will be desklets, or desktop widgets, such as for system monitor, terminal, and picture, video, and slideshow frame; themes with configurable color schemes; calendar events similar to those in KDE; and new applets including an email notifier and an RSS reader similar to Pulse.

Also coming will be bump maps and a control center governing settings for both Cinnamon and GNOME properties, among other features.

2. Nemo 1.8

Cinnamon's default Nemo file manager, a fork of Nautilus, will be upgraded to version 1.8 in the next Linux Mint release, according to the roadmap. Along with it will come an action API, disk management, file preview capabilities, and user interface improvements.

3. MDM 1.2

Version 1.2 of the Mint Display Manager (MDM), meanwhile, will bring new capabilities as well. Themes, for example, will be able to have borders around text fields.

Other new features coming in Linux Mint 15 include user interface improvements for software management and the live installer as well as a new screensaver and driver manager.

Based on Ubuntu, Linux Mint issues new releases twice a year. The current version, “Nadia,” was rolled out in November.
