- Mining of Massive Datasets (PDF) — book by Stanford profs, focuses on data mining of very large amounts of data, that is, data so large it does not fit in main memory. Because of the emphasis on size, many of our examples are about the Web or data derived from the Web. Further, the book takes an algorithmic point of view: data mining is about applying algorithms to data, rather than using data to “train” a machine-learning engine of some sort.
- Lessons from Iceland’s Failed Crowdsourced Constitution (Slate) — Though the crowdsourcing moment could have led to a virtuous deliberative feedback loop between the crowd and the Constitutional Council, the latter did not seem to have the time, tools, or training necessary to process carefully the crowd’s input, explain its use of it, let alone return consistent feedback on it to the public.
- Thread a ZigBee Killer? — Thread is Nest’s home automation networking stack, which can use the same hardware components as ZigBee, but which is not compatible, also not open source. The Novell NetWare of Things. Nick Hunn makes argument that Google (via Nest) are taking aim at ZigBee: it’s Google and Nest saying “ZigBee doesn’t work”.
A collection of must-see keynotes from Velocity Santa Clara, with bonus videos of some of the best sessions.
Editor’s note: this post originally appeared on Steve Souders’ blog; it is published here with permission.
Velocity Santa Clara was our biggest show to date. There was more activity across the attendees, exhibitors, and sponsors than I’d experienced at any previous Velocity. A primary measure of Velocity is the quality of the speakers. As always, the keynotes were livestreamed — the people who tuned in were not disappointed. I recommend reviewing all of the keynotes from the Velocity YouTube Playlist. All of them were great, but here’s a collection of some of my favorites.
Start. Here. Scott Hanselman’s walk through the evolution of the web and cloud computing is informative and hilarious:
From tiny satellites to young programmers to reasoned paranoia, here are key talks from OSCON 2014.
Experts and advocates from across the open source world assembled in Portland, Ore. this week for OSCON 2014. Below you’ll find a handful of keynotes and interviews from the event that we found particularly notable.
How tiny satellites and fresh imagery can help humanity
Will Marshall of Planet Labs outlines a vision for using small satellites to provide daily images of the Earth.
Josh Clark and Tim O’Reilly on designing beyond screens, and beyond a single device.
As the Internet is increasingly embedded into our physical world, it’s important to start designing for physical and intentional interactions with interfaces to supplement the passive, data-gathering interactions — designing smart devices that service us in the background, but upon which we also can exert our will.
In this episode, Josh Clark (in an interview) and Tim O’Reilly (in a keynote) both address the importance of designing for contextual awareness and physical interaction. Clark stresses that we’re not facing a challenge of technology, but a challenge of imagination. O’Reilly argues that we’re not paying enough attention to the aspects of people and time in designing the Internet of Things, and that the entire system in which we operate is the user interface — as we design this new world, we must think about user needs first.
Can education and peer review keep a huge open source project on track?
When does a software project grow to the point where one must explicitly think about governance? The term “governance” is stiff and gawky, but doing it well can carry a project through many a storm. Over the past couple years, the crucial OpenStack project has struggled with governance at least as much as with the technical and organizational issues of coordinating inputs from thousands of individuals and many companies.
A major milestone was the creation of the OpenStack Foundation, which I reported on in 2011. This event successfully started the participants’ engagement with the governance question, but it by no means resolved it. This past Monday, I attended some of the Open Cloud Day at O’Reilly’s Open Source convention, and talked to a lot of people working for or alongside the OpenStack Foundation about getting contributors to work together successfully in an open community.
