Status of ongoing development of the 1.6 release of MATE.
You can test the development (and unstable!) packages of MATE Desktop 1.5, they are already available for some distributions:
Debian Wheezy / Linux Mint Debian Edition (LMDE)
You can add
deb http://dev.mate-desktop.org/debian wheezy mainto your
Ubuntu Quantal / Linux Mint 14
You can add
deb http://dev.mate-desktop.org/ubuntu quantal mainto your
You need to install the package mate-archive-keyring from the stable MATE repository:
sudo apt-key adv –keyserver keyserver.ubuntu.com –recv-keys 68980A0EA10B4DE8
1.5 packages, also if unstable, are already on official Fedora repositories.
1.5 packages are available through OBS: https://build.opensuse.org/project/repositories?project=X11:MATE
You can build 1.5 packages using PKGBUILDs from https://github.com/mate-desktop/archlinux-packages.
People tell me that I feel too much. But I don’t care. I don’t care.
I often draw out concepts before I take them. I think it makes it easier to visualize the composition of the photo. I put together a few of the sketches I did before each photograph, so you can see how the final product compares to the original sketch. Just thought it might be interesting haha :)
Ubuntu to drop alternate installer
The alternate installer, required when users want to configure cryptsetup, Logical Volume Manager (LVM) or software-based RAID arrays during installation, may disappear from Ubuntu as early as version 12.10. The idea is mooted in a proposal put forward by Steve Langasek, Engineering Manager at Canonical’s Ubuntu Foundation. According to Langasek, dropping the alternate installer image would represent a step towards reducing the number of Ubuntu installation images. The guided partitioner in ubiquity – the installer from the desktop live images – now contains extensions to set up cryptsetup for encrypting whole disks and to manage disks using logical volume manager. Both functions should, according to Langasek, also be available with manual partitioning soon. The changes are planned for Ubuntu 12.10, which is currently under development and due to be released in October. The ability to set up software-based RAID arrays using mdadm will not, however, be finished in time and ubiquity is unlikely to support this before Ubuntu 13.04. Langasek nevertheless proposes dropping the alternate installer in 12.10. Users who want to use RAID can continue to use Ubuntu 12.04 or, alternatively, install 12.10 as normal, set up a software-based RAID array manually and migrate their data to it. The decision will only affect Ubuntu proper – Ubuntu variants such as Kubuntu will continue to offer the option of creating images using the alternate installer, which will continue to use a Debian installer-based installation program.

ZaReason Launch The First Linux UltraBook
Ultra in name, looks, and price, the ZaReason UltraLap 430 is the worlds first user-orientated Linux Ultrabook.
Ultrabooks are a relatively new segment of the computing market. Defined (primarily) by Intel, Ultrabooks are thiner, lighter, and use less power than traditional notebooks.
They also carry a premium price tag.
So can the worlds first consumer-ready Linux Ultrabook find a foothold in a market dominated by cheap yet powerful devices?
I will leave the semantics of whether or not the Ultralap 430 can truly be classed as an Ultrabook to the pedants (for example I believe it’s 1mm thicker than Intel’s Ultrabook specs).
But that’s academic. For most of us a super-slim design with a low power-draw CPU and long battery life are the only requisites needed to be defined as ‘ultra’.
Alongside a 14.1″ LED backlit HD screen are the following internals:
- Intel i3-3217U @1.8ghz
- Intel HD 4000 Graphics
- 4GB DDR3 RAM
- 32GB SSD
- 1.3 Megapixel webcam
- 2xUSB 3.0, 1xUSB 2.0
- HDMI port
- Wifi, Bluetooth, Ethernet, card reader, etc
- “Multi-gesture trackpad”
When it comes to operating system ZaReason provide a choice of Ubuntu 12.04, Linux Mint, Kubuntu 12.04, Debian, Fedora, and more. Looking for Windows? You’re out of luck. It’s one OS they don’t offer – or provide drivers for.
Now the bit you’ll have been waiting for – the price.
The base price for the Ultralap 430 is $899.00. Is this steep?
It depends where you place value.
You can get better specc’d Ultrabooks on Amazon.com for less than $750. And this is with the so-called ‘Windows tax’ included.
But you won’t get an Ultrabook that has been specifically tailored to Linux. Nor will your money go to supporting a small-time hardware company with smaller margins whose support for the open-source ecosystem is just as vital as that of a developer or sponsor.
As ZaReason didn’t offer us a unit to review we can’t relay to you anything other than what they have said about it. Whether or not it is actually worth every dollar of its $899 price tag will be up to you to decide.
But if you’re in the market for a Linux powered Ultrabook do keep your eyes peeled – we have a hands on with the Dell Sputnik laptop coming up later this month.
WD Introduces WD Red (WD Specialized for NAS)
WD did everyone a favor when they reorganized their products under color-coded branding a few years ago. With the Blue (mainstream), Green (quiet and cool) and Black (performance) lines well laid out, consumers have a much easier time picking out the right drive for their application, rather than poring over spec sheets and complex model numbers. And now there’s another line to add to that list: Red. Designed specfically to be used in 1-5 bay NAS devices, the Red line has hardware and software features that make it suited for that particular climate, while delivering impressive performance and reliability. WD has worked with major NAS manufacturer’s to ensure compatibility with as many common NAS products as possible, and has a list of the tested devices here. The secret sauce in these drives is the firmware, or as WD is calling it NASware. NAS devices in the home are often used for bulk storage of media, they may have some shared documents and be used as back-ups, too; but they’re most often used to store movies, music andimages. ATA streaming command is featured in NASware, to alter the behavior of the drive while streaming media, in an effort to ensure smooth playback, even while serving mutliple streams. They’ve also included error correction optimizations to prevent a drive from dropping out of a RAID array while it chases down a piece of corrupt data. The downside is that you might see an artifact on the screen briefly while streaming a movie, the upside is that you won’t have playback pause for a few seconds, or for good depending on your configuration, while the drive drops off the RAID to fix the error. Then there’s the matter of performance. With quoted performance of around 150 MB/s these drives are nudging into Black territory. WD’s new balance mechanism contributes to this. By actively balancing the drive during use there’s no need to slow the drive down to prevent damage, so performance remains high. There’s also a reported power savings, which WD says will make up the price delta for these drives over the rest of the line through your power bill. Speaking of price, the MSRP for the 3.5” 1TB, 2TB and 3TB drives are $109, $139 and $189, respectively. And these drives are available at your favorite e-tailer starting today. Ganesh is patiently awaiting our review samples so he can put them through the ringer and see how they do.
