Linux OS creator Linus Torvalds has decided it's time for version 4.0 of the Linux kernel. The news didn't
come as a surprise to most in the IT community, however.
To be sure, Torvalds has been wondering about Linux kernel release numbering for a while, notably
in a Google+ post last week.
He now seems to have taken the plunge in the direction, by declaring that the version of the
kernel he's working in is “Linux 4.0-rc1”. In a recent poll, about 56 percent of Linux users say they felt the time is right to go for version 4.0 of the kernel.
Torvalds writes “People preferred 4.0, and 4.0 it shall be. Unless somebody can come up with a
good argument against it, that's what it will be.”
Over on Git, Torvalds is even more blasé about the numbering change, offering the following
“After extensive statistical analysis of my G+ polling, I've come to the inescapable
conclusion that internet polls are bad.”
He goes on to deride responses to the poll before saying “But hey, I asked, so I'll honor the votes.”
Torvalds says the new release is small, but the full list of additions to version 4.0 look to be
pretty substantial-- on top of non-disruptive patching, the new version will support IBM's new Z-13
mainframe, Intel's Quark system-on-a-chip, support for the the OASIS Virt-IO 1.0 specification
and lots of graphics enhancements over and above what would reasonably be expected.

For the past two to three years, Ubuntu on mobile phones has been an ongoing project for the
Ubuntu team and quite an ambitious one at that.
Much like Microsoft and its new One Windows ideology, Team Canonical hatched the scheme for
a unified cross-device application ecosystem long ago, but progress has been rather slow in and of
To be sure, Meizu has been a critical part of the new OS development program at Canonical
with various demo builds and a rumor of a Ubuntu-powered Meizu mobile handset arriving soon, ever
since the MX 3 was the company's flagship offer.
Today, Meizu posted a rather interesting teaser on Facebook. The image of the new smartphone
seems to suggest a new OS, which will join the ranks of Flyme and YunOS and probably be unveiled at
this year's MWC.
We can instinctively point a finger towards Ubuntu Touch, which we will hopefully see in mass-production
This tidbit is further backed up by some rumors of an Ubuntu MX4 hitting the market, possibly in March or April.
The current flagship device has been a long-standing candidate for the Ubuntu experience, but we
can definitely expect some surprises here and there.
Last week, Canonical threw a curve ball by announcing that the BQ Aquaris E4.5 will be the
pioneer of Ubuntu on a Smartphone.
Keeping that element in mind, it's not certain if the MX-4 or MX-4 Pro version will offer a
higher-end hardware for the new OS or if Meizu will bring in an entirely new phone to the scene. Time
At any rate, and no matter how you look at this, the news is exciting. The Ubuntu Touch platform
itself is an interesting concept from Canonical.
The main idea behind it is a uniform Linux kernel and a set of base technologies that form
a cross-device application platform.
What this implies is an improved level of uniformity and compatibility, allowing users to share pretty
much the same set of applications, both on mobile and desktop devices.
To further add to the excitement, Ubuntu Touch also promises a full desktop experience and perhaps
even in the near future, a full desktop Ubuntu session running straight from the phone or tablet once
hooked up to a larger screen.
The latter, also known as "Full Desktop Convergence" is kind of experimental at this time, so it
might be a little while until we are actually able to dock our phones and use them as an everyday work
PC replacement for example.
There are also some hardware requirements for the feature to work correctly, but they are definitely
not out of reach for current generation mobile devices so let's hope we finally see a full-featured
Ubuntu experience on a Meizu device soon.
It's now confirmed today that version 3.19 of the Linux kernel has been released today by Linux OS inventor
Linus Torvalds. News of the release emerged in a typically economical Sunday evening post to the Linux Kernel Mailing List,
in which Torvalds noted that there are still a couple of bugs in the release but they were pretty obscure so “while I
was tempted a couple of times to do an rc8, there really wasn't any reason for it,” he was quoted
New in this release is improved product support for Intel and AMD graphics, plus support for LZ4
compression in the SquasFS which should make for better Linux performance on Live CDs. (Do people still
run Linux off of live CDs?)
Owners of Lenovo, Dell, Acer and Toshiba hardware will now find Linux plays better with some of
their unique hardware features, especially keyboard backlights. And there's been a few more changes.
For example, the KVM Hypervisor has dropped support for the IA-64 chip, a milestone in that architecture's
To be sure, Torvalds' post says that the next version of the Linux kernel will be known as 3.20.
That's not something he was keen on saying in late 2013, when he said “I would actually prefer to not
go into the twenties, so I can see it happening in a year or so, and we'll have 4.0 follow 3.19 or something
Torvalds' musings at the time imagined release 4.0 might be dedicated to “just stability and bug-fixes”.
Little or nothing's been heard of that idea in the months since, so release 3.20 looks like more of the same.

Linux OS code originator Linus Torvalds has publicly given some of his views on internet
security at the linux.conf.au held last week and seems to be closer to Google's way of thinking
than Microsoft's. Then again, he's been like that for a while now.
Torvalds, along with Debian representatives Bdale Garbee, Samba man Andrew Tridgell, and kernel
coder Rusty Russell spent an hour answering conference attendees' questions last week.
During a discussion about Linux security, Torvalds said-- “I'm an avid believer in just
disclosing responsibly. Security issues need to be made public. And there are people that will
argue me on this and have argued for decades, that you never want to talk about security problems
because that only helps the bad guys. The fact is that I think you absolutely need to report them
and and you need to report them in a reasonable time frame.”
Torvalds says on the kernel security mailing list that the disclosure time is five working days,
“which for some people is a bit extreme.”
“In other projects, it might be a month or a couple of months,” he continues. “But that's so
much better than the years and years of silence which we used to have in the past, he added.”
Might Torvalds have been aware of Google's twin disclosures of as-yet-unpatched Windows flaws last
week? Torvalds did seem to be more sympathetic to Google's approach of giving vendors 90 days to
disclose a security bug than other approaches that see vendors sit on flaws until they are ready
to release a fix.
Microsoft's regular Patch Tuesdays is one such example of that thinking at work and, we now know,
can see the company hold back fixes for bugs it knows about if it can't prepare a remedy in time
for a release.
For its part, Oracle releases security patches every ninety days or so. Torvalds' speech has also
attracted much attention for his remarks on his infamous intemperance.
“I'm an unpleasant person and you probably know that about me. Some people think I am nice
and some people are then shocked when they learn different. I'm not a nice person and I don't care
about you,” he told the conference.
“I care about the technology and I care about the kernel,” he said, going on to say that disagreements
will always erupt once discussions go beyond those topics.
Torvalds went on to make remarks about what he called “diversity in open source” in the
Linux community, saying it is “not about gender, not about skin color” and that the Linux community
is already very diverse as it comprises abrasive grumps like himself and others whose skills and
personality types enable different types of contributions that advance the cause.
He then went on to say that his attitude comes from the fact that he likes arguing and that
“I'm just not a huge believer in politeness and sensitivity being preferable over bluntly letting
people know your feelings,” he told the audience.
Linux OS originator Linus Torvalds has released version 3.18 of his popular 32 and 64-bit kernel. It was
released last night, after what Torvalds wrote was a tiny patch to get release candidate
The new version's headline features for business users are better resumption for Linux servers,
more support for the The Flash-Friendly File-System (FFFS) and some RAID-friendly tweaks to BTRFS.
There's also a lot more of support for graphics devices from NVIDIA and AMD, as well as a few other
Torvalds' announcement also says “I'd love to say that we've figured out the issue that
plagues 3.17 for a couple of people, but we haven't.”
The problem Torvalds is referring to appears to be an occasional lockup in Linux 3.17, perhaps
when running Xen.
Some testers of the Linux 3.18 release reported similar issues and the problem appears also to
manifest itself in the last Linux release.
Whatever the source of the problem, it's not of sufficient magnitude to have stopped the release
of the 3.18 kernel in the first place.
To be sure, Torvalds has now opened the merge window for Linux 3.19. Lately, new releases of the Linux kernel seem
to appear about every six to eight weeks or so.
Torvalds is making his usual pilgrimage to Linux.conf.au, which this year takes place in Auckland,
New Zealand in mid-January.
Between the festive season and that particular trip, the smart money would be on 3.19 landing sometime in mid-March
or early April 2015.

The marked differences and the strong variations in opinion over Debian's future direction
has prompted the group to launch a new fork of its Linux distribution over the weekend.
The disagreements centred on various plans to replace the sysvinit system management toolkit
with systemd, a similar but less-Linux-specific set of tools.
The “No” camp complained that systemd is not well-aligned with Unix philosophies, reflects
the rise of a “do-ocracy” whereby effort trumps quality and steers Debian in the direction of
The “Yes” camp are said to largely come from the ranks of Gnome developers. Negotiations have
considered making systemd optional, but those talks appear not to have gone well if this post
are anything to go by-- it announces a fork called Devuan.
Devuan's backers call themselves the “Veteran Unix Admin Collective” and, on their new site offer
the following rationale:
“Devuan aims to be a base distribution whose mission is protect the freedom of its community
of users and developers. Its priority is to enable diversity, interoperability and backward
compatibility for existing Debian users and downstream distributions willing to preserve Init's
The webpage goes on to explain that “Devuan will derive its own installer and package repositories
from Debian, modifying them where necessary, with the first goal of removing systemd, still
inheriting the Debian development workflow while continuing it on a different path-- free from
bloat as a minimalist base distro should be.”
A target “spring of 2015” release will see users “be able to switch from Debian 7 to Devuan 1
smoothly, as if they would dist-upgrade to Jessie, and start using our package repositories.”
The group's intention to develop a distribution “free from bloat as a minimalist base
distro should be” may also set some teeth grinding.
Whatever your position is on this issue, Devuan is now a real thing. A GitHub page is
being populated, and it's possible to make donations.
Jeff Waugh, a former member of the Gnome Foundation board says he feels “The 'no systemd'
stuff is a stupid premise, for an audience of a tiny, unpleasantly vocal minority.”
“There’s no way it will attract the kind of sustained maintenance that Debian has achieved for
over 10 years,” he said. “For a fork or child distribution to work, it has to solve a real problem.
Doesn’t include systemd is not a real problem,” he added.
Waugh also feels “it’s very early in the lifetime of systemd, so it would be wiser to see
how it goes before throwing additional tools around as some folks have done already.”
Linux vendor Suse kicked off this year's Suse Conference in Orlando by announcing that it's
getting into the software-defined storage business, starting early in 2015.
The company made a new offering, known simply as Suse Storage, available in private beta
beginning on Tuesday, with general availability expected for the first half of next year.
That Suse should want a piece of the storage market should come as no surprise. In a statement
announcing the new offering, Suse Storage product manager Larry Morris said the storage
market is "poised for disruptive change, just like the server market was fifteen years ago."
And he might be right about that, but what is somewhat unexpected is that Suse has chosen to
hitch its storage ambitions to the open source distributed block, object, and file storage system
Inktank, the company behind Ceph, was acquired by Suse rival Red Hat in April of this year for
$175 million and is now a wholly owned subsidiary.
But while Red Hat still offers Inktank Ceph Enterprise as a commercial product, the core
Ceph software still remains open source, meaning that there's nothing preventing Suse or other
companies from rolling distributions of their own.
A pure-software offering, Ceph is designed to run on commodity servers and disk arrays as
an alternative to costly equipment from traditional storage vendors like EMC, Hitachi Data Systems,
HP, IBM and NetApp.
In a recent report, Gartner said it expects Ceph and similar open source storage systems to
reach 20 percent market share by 2018, as escalating enterprise data retention drives up demand
for lower cost but reliable storage systems.
The first version of Suse Storage will be based on the Firefly release of Ceph, the company said.
Pricing was not discussed and no shipping date was given, but companies that would like to participate
in the beta program can contact Suse to get on the list.
Suse also added that it has teamed up with SAP to help lure Suse customers to the SAP HANA
data analytics platform.
Under the new program, qualifying startups will be able to download a virtual machine that
comes preloaded with a developer edition of HANA running on Suse Linux Enterprise Server and try
it out for six months at no charge.
They'll also be eligible for free training from Suse's Certified Linux Administrator (CLA)
