Ubuntu doubles down on Unity, will focus on mobile and the cloud in 2013

In less than a decade, Ubuntu has become the most well-known desktop Linux variant. With its heavy focus on user interface and usability, it’s easy to see why Ubuntu has become a popular introduction to the world of Linux. Recently, the developers have switched away from traditional interfaces to a more streamlined UI called Unity. The new look alongside integration with Amazon search from the desktop have raised the ire of a number of Linux diehards. Mark Shuttleworth, founder of Ubuntu, has recently made a blog post explaining the plans for Ubuntu in 2013. Anyone expecting a change of heart about Canonical’s recent UI and UX decisions is in for some disappointment.

Shuttleworth addresses his detractors by saying, “If you’ve been arguing over software licenses for the best part of 15 years then you would probably be fine with whatever came before Ubuntu.” Essentially, he dismisses the hardcore Linux enthusiast by implying Ubuntu isn’t designed for them. Instead, he is focused on Ubuntu becoming approachable and usable by the largest number of people. While the goal of making a free and open-source operating system for the whole world is incredibly admirable, it shouldn’t come at the expense of the community that has made Ubuntu into the juggernaut it currently is.

The South African millionaire continues to explain that in the coming months, Ubuntu development will be focused heavily on moving into the tablet and smartphone space while simultaneously focusing on cloud computing. While this is undoubtedly the best way forward, it will obviously rub some Linux enthusiasts the wrong way. A vocal minority of Linux users and developers are stuck in a 1990s mindset where the desktop is king, and everything should be focused on power users. With that sort of thinking, Linux has never become a substantial player in the desktop space — but taking its powerful underpinnings and making it approachable has made Android one of the most widely used consumer operating systems in the world. The idealism underpinning Ubuntu hasn’t always been implemented perfectly, but Canonical is making huge strides in usability. Hands down, Ubuntu is the most interesting and progressive consumer oriented Linux distribution available today.

It would be ridiculous to think Ubuntu would stop iterating on the idea of a user-friendly Linux distro just to please some uppity neckbeards. However, it would be nice if the Canonical leadership weren’t so openly hostile towards their detractors. Instead of eye rolling and explaining that Ubuntu isn’t made with them in mind, Canonical should embrace the vocal minority. Throw them a bone by highlighting how easy it is to switch to vanilla Gnome, KDE, or Xfce, and embrace how diverse the Linux community can be. In turn, the old school Linux fans shouldn’t expect Ubuntu to stagnate simply for their comfort. The times they are a-changin’, folks.

The poor get poorer and the rich get richer with Apple’s iPad-based textbooks

The poor get poorer and the rich get richer with Apple’s iPad-based textbooks

Apple’s iBooks2’s reinvented textbooks really are something. They’re gorgeous, they’re fast, they’re real-time interactive with up to date information and they’ll only cost $14.99 or less. But, to use them, you’ll need an iPad–minimum list price: $499.

Can you afford that for your kids? Can your school board? I could, but I’ve been lucky enough to do well in my career and I only have the one daughter. There’s certainly no way that any county I’ve ever lived in during my life in West Virginia, Maryland, or North Carolina could afford to give every student from K to 12 an iPad. They’re lucky when they can provide any kind of computer seat for each kid.

That’s why there have been programs like the so-called $100 laptop: the OLPC (One Laptop per Child). The OLPC project aimed to put first low priced notebooks, the XO-1.5 and now tablets, the OLPC XO Tablet, into the hands of kids who don’t go to private schools.

These XO Tablet is powered by a 1GHz Marvell Armada PXA618 processor, and have a mere 512MBs of RAM. It can run a minimized version of Red Hat’s Fedora Linux with the simplified Sugar interface on top of that and it can also run Android. Price: $100.

Compared to an iPad, the XO Tablet is junk. But, they’re also much more affordable and isn’t getting information into the hands of students what a textbooks are all about? Wouldn’t it be great if you could use Apple’s iBook textbooks on an OLPC? Or, for that matter, any of the other low-priced Android tablets or tablet/e-book readers like the Barnes & Noble Nook Tablet or Amazon Kindle Flame? Don’t hold your breath.

Apple seems to have no interest in bringing iBooks to Windows PCs, Linux computers, Android tablets or, for that matter, even its own MacBook Air. Low-end Android tablets? Give me a break!

What’s that you say? Why can’t you just create an ePub version of your iBook textbook and sell it to whomever? Well, first, iBooks Author can create books in iBook format, PDF and text. The iBook format appears to be a variation of the popular and open EPUB format. Closer examination of the format reveals, though, that it appears to be a proprietary fork of EPUB.

Numecent announced today availability of Application Jukebox for Red Hat Enterprise Linux and support for Red Hat Enterprise Virtualization 3.0 in line with the availability of the platform today.

Red Hat Enterprise Virtualization for Desktops combined with Numecent Application Jukebox delivers a flexible and comprehensive application delivery platform for your virtualized desktop infrastructure. Whether you are considering a migration to a cloud computing model or looking at a traditional hosted desktop solution, Application Jukebox can deploy your applications to the users who need them, when they need them.

“Using Jukebox technology, you can convert traditional Windows software to be delivered to Red Hat Enterprise Virtualization-hosted desktops,” said NavinThadani, senior director, Virtualization Business at Red Hat. “”Combining Jukebox technology with the performance, scalability and cost benefits of Red Hat Enterprise Virtualization 3.0, customers have a compelling combined solution.”

Application Jukebox Server on Red Hat Enterprise Linux can translate to a lower TCO by offering better performance and a consistent backend OS. Application Jukebox saves virtualization resources by reducing the size of desktop images since applications do not need to be included, and also by reducing the number of desktop images since different images no longer need for separating conflicting applications. Powerful license compliance and management keep application costs down and under control.

“Application deployment is the last mile of desktop delivery, virtual or not,” said Dr. Arthur S. Hitomi, Chief Technology Officer and Founder of Numecent. “With Red Hat Enterprise Virtualization for Desktops, hosted virtual desktops have never been more scalable, automated and native.”

Windows 8 Secure Boot – or How Microsoft Is Riling Up the Linux Masses

Windows 8 Secure Boot – or How Microsoft Is Riling Up the Linux Masses

“The trusting (ironic this is all about Trusted Computing) side of me wants to believe this is just a spec from Microsoft to ensure their OS runs correctly on hardware platforms,” said Slashdot blogger yagu. “But history, track record, and all evidence to Microsoft’s tactics since forever make me nervous… “I’m quite convinced (my opinion) Microsoft’s motives remain the same as always.”

What a difference a week makes.

It was just the other day that Linux bloggers were celebrating the news from researcher Net Applications that desktop Linux had surged in popularity in recent months.

Now, the mood in the blogosphere has plummeted once again as a result of the latest developments on the Windows 8 front. Secure Boot, that is — a topic astute readers may remember from last fall but that lately seems to have taken a turn for the worse.

Exhibit A: “Microsoft confirms UEFI fears, locks down ARM (Nasdaq: ARMHY) devices,” as the the Software Freedom Law Center (SFLC) recently summed it up.

Exhibit B: “Why UEFI secure boot is difficult for Linux,” in which Red Hat (NYSE: RHT) developer Matthew Garrett explains why things aren’t looking much better on Windows 8 PCs.

Bottom line? “The Controversy Continues,” as it was put at PCWorld.

‘The Exact Thing They Said They Wouldn’t Do’

“Controversy,” of course, is Linux Girl’s middle name, so she whipped out her Quick Quotes Quill and started taking notes.

“And there we have it,” began consultant and Slashdot blogger Gerhard Mack down at the Linux blogosphere’s rowdy Punchy Penguin Saloon last Friday. “Microsoft is doing the exact thing they said they wouldn’t do, and I still can’t imagine how they think this will actually make things more secure.

“I buy PCs based on my ability to do what I want with them, and the same goes for my mobile phone,” Mack added. “I don’t tolerate Android makers with locked boot loaders, and I already wouldn’t buy an iPhone or iPod. This is just one more set of products I will never spend money on.”

Barbara Hudson, a blogger on Slashdot who goes by “Tom” on the site, had even more choice words on the issue.

‘They Need Software Viagra’

“Nasty, short-sighted, and if you think about it for a moment, a blatant admission that Microsoft (Nasdaq: MSFT), despite having a golden opportunity to abandon all their previous deficient coding practices and cruft when moving to new hardware, still isn’t able to produce an OS that is more than semi-hardened,” Hudson told Linux Girl.

“They need to see a doctor to get some software Viagra,” Hudson added.

“This is not about security,” blogger Robert Pogson agreed. “The local user can always compromise a PC in hand one way or another.”

Rather, “this is about creating a rejuvenated monopoly on ARM,” Pogson asserted.

‘Good-Bye, M$’

Fortunately, “it won’t work, Pogson predicted. “The OEMs have seen FLOSS sell like hotcakes on ARM and they know it is profitable. They no longer need M$ to ensure profitability.”

Some will “produce ARMed units to please M$, but consumers won’t buy them because they know they no longer need M$ on small cheap computers,” he added. “Other initiatives of Wintel will fail similarly: ultrabooks and ’8′ on anything. ’7′ on x86/amd64 could not save M$ from a drop in revenue; ’8′ will not either on ARM or x86/amd64.”

With “an effective monopoly on retail shelves, M$ cannot get more than 60 million PCs per quarter to take their license,” Pogson pointed out. “30 million are installing something else — old copies of XP or GNU/Linux. The world is tired of their old monopoly and wary of a new one. Good-bye, M$.”

‘Microsoft Products Dominate Shelf Space’

Indeed, it’s the purchase decision that Hyperlogos blogger Martin Espinoza was focused on.

“I participated in some spirited conversation on this issue with some apparent astroturfers who insisted that if I don’t like hardware which denies my right to choose what software I’d like to run on it, my sole recourse is not to buy it,” Espinoza told Linux Girl.

“This, of course, ignores numerous issues, including the secondary market,” he pointed out.

“It is a valid point in that when we purchase this hardware we are funding our own abuse, but the simple truth is that the masses purchase that which is presented to them, and Microsoft products dominate shelf space,” Espinoza concluded. “When the choices presented are Windows on x86 and Windows on ARM, the user will end up with ‘secure’ boot either way.”
