- Using Logs to Build Solid Data Infrastructure — (Martin Kleppmann) — For lack of a better term, I’m going to call this the problem of ‘data integration.’ With that, I really just mean ‘making sure that the data ends up in all the right places.’ Whenever a piece of data changes in one place, it needs to change correspondingly in all the other places where there is a copy or derivative of that data.

- Project Advice (Daniel Bachhuber) — for leaders of distributed teams. Focus on clearing blockers above all else. Because you’re working on an open source project with contributors across many timezones, average time to feedback will optimistically be six hours. More likely, it will be 24-48 hours. This slow feedback cycle can kill progress on pull requests. As a project maintainer, prioritize giving feedback, clearing blockers, and making decisions.
- YAGNI (Martin Fowler) — cost of build, cost of delay, cost of carry, cost of repair. Every product manager has felt these costs.
Key insights from DevOps, Web operations, and performance.
People from across the Web operations and performance worlds are coming together this week for the 2015 O’Reilly Velocity Conference in Santa Clara. Below, we’ve assembled notable keynotes, interviews, and insights from the event.
Think like a villain
Laura Bell outlines a three-step approach to securing organizations — by putting yourself in the bad guy’s shoes (without committing actual crime, she stresses):
- Think like a villain and be objective: identify why and how someone would attack your company; what is the core value they’d come to steal?
- Create a safe place to create a little chaos: don’t do it live, but find a safe place without restriction and without fear to break things, to practice creative chaos.
- Play like you’ve never read the the rule book: Not everyone plays by the same rules as you, so to protect yourself and your company, you have to think more like the person willing to break the rules.
Modern fintech is going to create formal, standard records about economies where none existed before.
Request an invitation to Next:Money, O’Reilly’s conference focused on the fundamental transformation taking place in the finance industry.
A relatively commonplace occurrence — credit card fraud — made me reconsider the long-term impact of financial technology outside the Western world. I’ll get to it, but first, we need to talk about developing economies.
I’m halfway through Hernand de Soto’s The Mystery of Capital on the advice of the WSJ’s Michael Casey. Its core argument is that capitalism succeeds in the Western world and fails everywhere else because in the West, property can be turned into capital (you can mortgage a house and use that money to do something). The book uses the analogy of a hydroelectric dam as a means of unlocking the hidden, potential value of the lake.
But in much of the world, it is unclear who owns what, and as a result, the value of assets can’t be put to work in markets. In the West, we take concepts like title and lien and identity for granted; yet, these systems are relatively new and don’t exist around the world. As de Soto noted in his book, in the Soviet Union, unofficial economic activity rose from 12% in 1989 to 37% in 1994. Read more…
The O'Reilly Radar Podcast: Josh Clark on the world as an interface, avoiding data rash, and the importance of play.
Subscribe to the O’Reilly Radar Podcast to track the technologies and people that will shape our world in the years to come.
In this week’s episode of the Radar Podcast, O’Reilly’s Mary Treseler chats with Josh Clark, founder of design agency Big Medium (formerly known as Global Moxie). Clark talks about the changing nature of his work as the world itself becomes more of an interface, how to avoid “data rash,” and why in this time of rapid technology growth it’s essential for designers to splash in the puddles.
The world is the medium
The influence of the Internet of Things is beginning to touch every aspect of our lives, from how we communicate to how we work to how we play. This fundamental shift away from screens to the real-world around us not only is influencing how designers approach their craft, but is changing the medium itself in which designers work. Clark talked about this shift and how it’s affecting his own work:
Over the last couple of years, I’ve found the nature of my work has been changing as well as my interests. I think the culture of digital design is changing, too, as we start moving off of screens. It felt like an opportunity to redefine my own work, so I also did that with my agency and changed its name to Big Medium. The idea of that being that the Internet itself is a pretty big medium, and in fact starting to expand beyond the bounds that we’ve traditionally associated it with, which is the screen. Increasingly, as we’re seeing connected devices — the smart phones were kind of the leading edge of this, but now we’re starting to see wearables and the Internet of Things — this idea that the Internet is becoming embedded in our environment and in everyday objects means that anything can be an interface.
My work is starting to engage more and more with that truly big medium, which is the world itself. Finally, the world is the interface, which of course it always has been, but now we’re able to create digital experiences that belong to the world that we actually move in instead of us having to dive into the screens.
A new partnership between O’Reilly and DataStax offers certification and training in Cassandra.
I am pleased to announce a joint program between O’Reilly and DataStax to certify Cassandra developers. This program complements our developer certification for Apache Spark and — just as in the case of Databricks and Spark — we are excited to be working with the leading commercial company behind Cassandra. DataStax has done a tremendous job growing and nurturing the Cassandra community, user base, and technology.
Once the certification program is ready, developers can take the exam online, in designated test centers, and at select training courses. O’Reilly will also be developing books, training days, and videos targeted at developers and companies interested in the Cassandra distributed storage system.
Cassandra is a popular component used for building big data and real-time analytic platforms. Its ability to comfortably scale to clusters with thousands of nodes makes it a popular option for solutions that need to ingest and make sense of large amounts of time series and event data. As noted in an earlier post, real-time event data are at the heart of one of the trends we’re closely following: the convergence of cheap sensors, fast networks, and distributed computation.

A look at AR today and how we need to design it for tomorrow.
Attend O’Reilly’s Solid Conference, June 23–25, in San Francisco. Solid is our conference exploring how the collision of software and hardware is fueling the creation of a software-enhanced, networked physical world. Helen Papagiannis will speak at Solid on June 24.Unlike virtual reality (VR), augmented reality (AR) provides a gateway to a new dimension without the need to leave our physical world behind. We still see the real world around us in AR, whereas in VR, the real world is completely blocked out and replaced by a new world that immerses the user in a computer generated environment.
The most common definition of AR to date is a digital overlay on top of the real world, consisting of computer graphics, text, video, and audio, which is interactive in real time. This is experienced through a smartphone, tablet, computer, or AR eyewear equipped with software and a camera. Examples of AR today include the translation of signs or menus into the language of your choice, pointing at and identifying stars and planets in the night sky, and delving deeper into a museum exhibit with an interactive AR guide. AR presents the opportunity to better understand and experience our world in unprecedented ways.
AR is rapidly gaining momentum (and extreme amounts of funding) with great advances and opportunities in science, design, and business. It is not often that a whole new communications medium is introduced to the world. AR will have a profound effect on the way we live, work, and play. Now is the time to imagine, design, and build our virtual future. Read more…
