5 Favorite Sessions from Collaboration Summit Attendees

Leave a comment

By libbyclark

Now more than halfway through the Linux Foundation’s Collaboration Summit in San Francisco, attendees have started to weigh in on the best sessions and experiences so far. Some cited Monday’s keynote presentations from heavy hitters such as Samsung and Jaguar Land Rover. Others focused on the technical discussions in Tuesday’s sessions, which covered a range of topics from Automotive Grade Linux to kernel scheduler load balancing. And for some, simply meeting the developers on the other side of an email list provided the best experience at the conference.  

 

“It’s been great learning about the open source projects, in particular Jaguar and Samsung and the collaboration they’re looking for and that we can offer.

“Whether you work for a different company or not, it seems like you can really participate. I’m looking forward to some of the other technical presentations where I can learn about Linux and how it’s changing.” – Carol Sanders, Vyatta. 

 

 

 

 

 

“The subjects are great, but what’s even greater is getting to meet people and have discussions with people on the other side of engineering from different companies. I got to meet people I’ve been working with for several years but I’ve never met with them.

“Even some of the presentations we had that weren’t direclty related to what our company does triggered a lot of good ideas that I can bring back to the company and gave me some ideas for changes.

For cloud computing we talked about what’s missing and what can be done and especially from a storage perspective. We know we’re doing a lot on our end that’s really good but there are parts of the Linux kernel that need to be added as well.” – Abdel Sadek, NetApp.

 

 

 

“I was particularly interested in the Linux weather forecast by Jon Corbet yesterday. It presented some challenges that we’re going to face this coming year. Some of which I wasn’t aware, particularly in the new architectures with big.LITTLE and how that will imply changes in course scheduling code. Me working in performance issues, I find that attractive and challenging.

“I’ve been impressed with the keynotes and event organization as well. I hope tomorrow will be just as good.” – Davidlohr Bueso, Hewlett-Packard. 

 

 

 

 

 

“Today I attended ACPI 5.0 improvements, which is really interesting. I’ve been kind of watching the Linux mailing lists on Linux LKML. It gave me insight into balance bewtween ARM and ACPI and how we can use the same infrastructure to transparently implement.

“Also, being able to add GPIO interrupts and such, and see where I can contribute, possibly. The second one I heard about was power scheduling which was very insightful. There are a lot of questions to be answered in terms of getting it to primetime.

“And the big thing I’m getting out of this conference is

My Linux Foundation Collaboration Summit Picks and Details on Live Video Access to Keynotes

By amcpherson

For The Linux Foundation, April is not the cruelest month: it’s one of the busiest. Every year, we hold our Collaboration Summit in mid-April to bring together our members, Linux and open source community developers, open source legal minds, and large scale Linux and open source users in an intimate setting. Even as The Linux Foundation has expanded its event lineup to include LinuxCon, CloudOpen, Automotive Linux Summits, and more throughout the world, this remains our original event, and because of that, as well as it’s small size and unique format, it’s special to many of us in the community.

As we prepare I wanted to share some of my top picks for speakers and sessions, as well as remind everyone who can’t join us this year that you can watch the day 1 keynotes for free via live video stream. Just sign up on the Events website.

My picks include:

* Automotive crowd sourcing, presented by Jaguar Land Rover‘s Matt Jones. Not only will Matt be speaking about how we can open up the software design process for in-vehicle infotainment, but there will also be a Jaguar Land Rover on display at the event that includes a Linux-based infotainment system.

* Adapteva CEO Andreas Olofsson will talk about how Kickstarter helped them create the $99 supercomputer, the Parallela Project, and how that works is transitioning parallel computing through open hardware. You can get more of a sense for Andreas and his perspectives in this recap of his recent LiveLinuxQA on Twitter.

* Collaborative Projects panel. This panel will include community leadership from a variety of the Collaborative Projects we host here at The Linux Foundation. Projects represented on the panel include Yocto Project, OpenMAMA and a special guest to be announced onsite.

* Netflix’ Adrian Cockcroft, director of architecture and cloud systems, will share how the company is using Linux and managing cloud services for one of the most highly-consumed services today. He will also detail Netflix’ cloud platform. Should be interesting.

* Jon Corbet will present the latest Linux Weather Forecast. This is a “don’t miss.” Jon’s presentations are always entertaining and thorough. If you want to know what’s taking shaping in the Linux kernel, this is the keynote to attend.

I’d also encourage people to drop into a variety of the sessions on days 2 and 3. I’m especially looking forward to GNOME’s Karen Sandler on bringing more women to free and open source software; Creative Commons’ Mike Linkvayer on “Software Eats the World;” and Red Hat‘s session on persistent memory for Linux for new storage technologies and interfaces.

You can view the complete Collaboration Summit schedule to see what else you might want to check out next week online or onsite.

Lastly, we’ll be hosting a Xen Project birthday party Monday night at the Julia Morgan Ballroom from 6 p.m. –

Jon Corbet Mulls Linux Kernel Changes

Leave a comment

By libbyclark

Collaboration Summit in April.” class=”caption” />

Now that the Linux kernel 3.9 merge window is closed, it’s safe to say we know what features will be included in the next kernel release. What lies beyond is predictable, still, but will likely hold a surprise or two. That’s where the annual Linux kernel weather report comes in.

Delivered by Linux kernel contributor and LWN.net co-founder Jon Corbet at Collaboration Summit in San Francisco April 15-17, the forecast will help prepare the Linux community for the year ahead.

In this Q&A, Corbet gives us a preview of his talk, reveals some kernel changes that surprised him last year, and discusses some of the biggest challenges kernel developers face in the months and years ahead.

What changes to the kernel over the past year have surprised you?

I do try not to be surprised by kernel changes – it’s my job to be on top of that stuff, after all 🙂

One of my biggest surprises, I guess, was when I realized that the Android developers had dropped their wakelock/suspend blocker implementation in favor of the solution that had been merged into the mainline kernel. A long-running, high-profile, bitter fight had been resolved quietly with almost nobody even noticing, and one of the biggest differences between the Android and mainline kernels is no more. A lot of credit is due to the developers in both the Android and mainline communities for their hard work in creating a solution that is acceptable to everybody involved.

Another surprise is the speed with which the bufferbloat problem has been brought under control. With a relatively small number of changes, many of the over-buffering problems in the Linux kernel were taken care of, to the point that the problem is pretty well solved for wired Ethernet networking. There is, of course, still a lot of work yet to be done, especially with wireless networking.

What features will we find in the 3.9 kernel?

We’ll get support for the ARC and Metag processor architectures. The “dm-crypt” subsystem enables the use of a fast (solid-state) drive as a front-end cache for slower storage. The ARM architecture now supports virtualization with KVM. User namespaces now work with almost all filesystems, making it possible to enable this feature in almost any kernel (though that may not yet be a wise thing to do).

What other new features are coming down the pike this year? 

Some of the more interesting work on the horizon may be the various solutions to the problem of scheduling on ARM big.LITTLE systems. The Linux scheduler was never written with asymmetric processors in mind, so it currently does not know how to schedule tasks to take advantage of the big.LITTLE architecture. The two existing patch sets try to solve this problem in very different ways; the “big LITTLE MP” work, in particular, will be the beginning of a new push to make the scheduler more power aware.

We will see the continuation of the ARM architecture cleanup work and, probably, true multiplatform ARM kernels for the first time. The integration of the Android code into the mainline will also continue.

What are some of the biggest issues kernel developers are tackling and how are they being addressed?

If You Don't Know Linux, You Better Learn Fast

lf infogfx jobs2013 FINAL

Jobs again this year were a major theme in the State of the Union address with the President saying that we must train our students for the jobs of tomorrow. Guess what? Those jobs of tomorrow are Linux jobs. Maybe the President didn’t realize he was talking about Linux, but we know that Linux is supporting the computing infrastructure that makes our 21st century lives possible. From the phones we use to the websites we frequent to the cars we drive, Linux is running it all. And nothing underscores this fact more than year-over-year demand for Linux talent to support its pervasiveness in every day life.

The 2013 Linux Jobs Report released today in partnership with Dice.com shows that demand for Linux talent is up for the second year in a row. Ninety-three percent of hiring managers say they will be hiring Linux pros this year. The report shows a significant spike in the areas of systems administration and DevOps. These jobs are filled by people who manage the massive data centers, cloud platforms and data analytics that run and inform each and every transaction companies and individuals conduct every day.

This year’s report for the first time surveyed both hiring managers and Linux professionals in an effort to provide a comprehensive picture of the state of the Linux jobs market. The results show that Linux pros are being aggressively pursued by recruiters; seventy-five percent of those surveyed said they have received a call in the last six months. And, more than 1/3 plan to make a move this year, representing an opportunity for employers. But according to the report, even more hiring managers than in 2012 are struggling to find experienced Linux talent (a full 90%).

As a community and an industry, we have a big job of our own: we must train students and professionals for the jobs of tomorrow: Linux jobs. Linux has experienced rapid growth in every area of computing over the last decade but we must be able to support that growth with talented professionals who know how to build and maintain Linux-based devices and systems.

The good news is anyone can get involved in Linux and they can do it right now. There are no barriers to entry here. As the experts have pointed out, you can start contributing today. A bug fix here, a patch submission there. If you’re looking for some guidelines on how to get started, check out kernel developer Jon Corbet’s guide on participating in the Linux kernel community. Also, take advantage of the variety of The Linux Foundation’s Linux training courses, which are taught by leaders from the Linux and Linux kernel communities.

We encourage people to move on this opportunity fast. Linux needs your support, the army is is building.

Who would have expected that a free operating system would spur jobs growth? It is possible to share, collaborate and grow the economy, …read more
