Cisco, a founding member of the Linux Foundation Initiative

Our Cisco colleague Anthony Grieco wrote a quick blog post over on the Cisco Security blog announcing that Cisco is a proud supporter and founder of the Linux Foundation initiative announced on April 24th.

We are pleased to help form a critical mass of governance, funding, and focus that will support the output of open source communities like OpenSSL. By working together as an industry, we can expect greater security, stability, and robustness for components that are critical to the Internet.

New Open MPI stable series launched: v1.8

April 11, 2014 at 9:00 am PST

Open MPI logoThe Open MPI project released version v1.8 last week.  This is a major release that heralds the beginning of a new production-ready series, full MPI-3.0 support, and a new OpenSHMEM implementation.

Open MPI is developed in a tick-tock fashion:

  • Odd-numbered series are focused on feature development and expansion
  • Even-numbered series are focused on stability and production usage

The even-numbered v1.8.x series therefore represents a new production-ready series that effectively deprecates the prior production-ready series (v1.6.x).

The First Open Source Project to Win the Interop Grand Prize…

… is none other than…  (drum roll, please!) … our one year old baby, OpenDaylight! My heartfelt congratulations go to the OpenDaylight committers and contributors, the open source collaborators who have poured their heart and soul into this wonderful project. This is indeed a remarkable event, considering the skepticism surrounding its start just about one year ago, in fact at Equinox. The Interop and OpenDaylight announcement captures the meaning of this accomplishment very well and on behalf of the OpenDaylight partners, I would like to thank the developers and users, to wish them continued success and strong adoption. Know that as long as core open source principles are alive and well our project will do well. Thank you, Interop panelists and conference attendees, and most of all, thank you Cisco colleagues, customers, and partners for building and embracing the base of what promises to be a star project. I am so proud of you!

In Search of The First Transaction

At the height of an eventful week – Cloud and IoT developments, Open Source Think Tank,  Linux Foundation Summit – I learned about the fate of my fellow alumnus, an upperclassman as it were, the brilliant open source developer and crypto genius known for the first transaction on Bitcoin.

Hal Finney is a Caltech graduate who went on to become one of the most dedicated, altruistic and strong contributors to open source cryptography. We are a small school in size, so one would think it’s easy to keep in touch; we try but do poorly, mostly a very friendly and open bunch, but easy to loose ourselves into the deep work at hand and sometimes miss what’s hiding in plain sight.

He was among the first to work with Phil Zimmermann on PGP, created the first reusable proof-of-work (POW) system years before Bitcoin, had just the right amount of disdain for noobs in my opinion, and years later, one of the first open source developers with Satoshi Nakamoto on Bitcoin, in fact the first transaction ever. There is a great story about Hal in Forbes this week, “My hunt for Bitcoin’s creator led to a paralyzed crypto genius, thank you, Hal Finney for going through with it, and Andy Greenberg for writing it. Sometimes it is very painful, shocking to see how things turn out, I think this is one of those moments when we realize how much this is going to mean to all of us, the brilliant minds of programmers like Hal Finney, who never sought the limelight, but did so much for us without asking for anything in return, who leave behind a long lasting contributions to privacy and security in our society, he is in fact a co-creator of the Bitcoin project. Do you realize that every bitminer successfully providing the required POW, should in fact reach the very same conclusion at the end of every new transaction… forever? You’d better accurately represent who was the very first. What a legacy to remember!

I often go to Santa Barbara to see a very, very close and dear person there, my daughter. But now, there is another reason to stop by and pay tribute to one of the finest there. We will all be in search of the first transaction, eventually.

ELC: An Introduction to the Video4Linux Framework

During this year’s Embedded Linux Conference in San Jose I will be presenting An Introduction to the Video4Linux Framework. As a long-term kernel contributor (since 2003), author of over 2000 kernel patches and co-maintainer of the video4linux kernel subsystem I have been working on improving that subsystem so it can handle the highly complex video capture and codec pipelines that are available on a modern SoC.

As part of that work a lot of attention was given (and still is!) to the supporting framework provided by the video4linux subsystem to simplify the driver code. Video is complex and driver developers should be able to concentrate on configuring the hardware without the V4L API getting in the way.

This presentation will demonstrate how to make a fairly simple video capture driver using the latest framework features. Using that framework greatly reduces the amount of work required to write a driver compared to what would have been needed just a few years ago.

You are all welcome to attend this presentation! And for those who are interested: on Friday there will be a video4linux mini-summit, see the announcement here.

Finally, if you have any questions about the video4linux kernel subsystem, please don’t hesitate to contact me at any time. I am always happy to answer them as best as I can.
