- Fix Mac OS X — each time you start typing in Spotlight (to open an application or search for a file on your computer), your local search terms and location are sent to Apple and third parties (including Microsoft) under default settings on Yosemite (10.10).

- A/B Testing at Netflix (ACM) — Using a combination of static analysis to build a dependency tree, which is then consumed at request time to resolve conditional dependencies, we’re able to build customized payloads for the millions of unique experiences across Netflix.com.
- Leslie Lamport Interview Summary — One idea about formal specifications that Lamport tries to dispel is that they require mathematical capabilities that are not available to programmers: “The mathematics that you need in order to write specifications is a lot simpler than any programming language [...] Anyone who can write C code, should have no trouble understanding simple math, because C code is a hell of a lot more complicated than” first-order logic, sets, and functions. When I was at uni, profs worked on distributed data, distributed computation, and formal correctness. We have the first two, but so much flawed software that I can only dream of the third arriving.
- Fake Identity — generate fake identity data when testing systems.
Trina Chiasson argues that data has arrived at the same threshold as coding: code or be coded; learn to use data or be data.
Arguments from all sides have surrounded the question of whether or not everyone should learn to code. Trina Chiasson, co-founder and CEO of Infoactive, says learning to code changed her life for the better. “These days I don’t spend a lot of time writing code,” she says, “but it’s incredibly helpful for me to be able to communicate with our engineers and communicate with other people in the industry.”
Though helpful for her personally, she admits that it takes quite a lot of time and commitment to learn to code to any level of proficiency, and that it might not be the best use of time for everyone. What should people commit time to learn? How to use data. Read more…
Liza Kindred on the evolving role of data in fashion and the growing relationship between tech and fashion companies.
In this podcast episode, I talk with Liza Kindred, founder of Third Wave Fashion and author of the new free report “Fashioning Data: How fashion industry leaders innovate with data and what you can learn from what they know.” Kindred addresses the evolving role data and analytics are playing in the fashion industry, and the emerging connections between technology and fashion companies. “One of the things that fashion is doing better than maybe any other industry,” Kindred says, “is facilitating conversations with users.”
Gathering and analyzing user data creates opportunities for the fashion and tech industries alike. One example of this is the trend toward customization. Read more…
Doug Cutting on applications of Hadoop, where "Hadoop" comes from, and the new partnership between Cloudera and O'Reilly.
Roger Magoulas, director of market research at O’Reilly and Strata co-chair, recently sat down with Doug Cutting, chief architect at Cloudera, to talk about the new partnership between Cloudera and O’Reilly, and the state of the Hadoop landscape.
Cutting shares interesting applications of Hadoop, several of which had touching human elements. For instance, he tells a story about visiting Children’s Healthcare of Atlanta and discovering the staff using Hadoop to reduce stress in babies. Read more…
The O'Reilly community shares stories of inspiring women in tech. Who inspired you?
October 14 is Ada Lovelace Day (ALD), an annual global event that recognizes not only the 19th century mathematician and aristocratic super nerd who wrote the first computer program, but other women in our community, too. ALD founder Suw Charman-Anderson’s goal is “to raise the profile of women in science, technology, engineering, and maths by encouraging people around the world to talk about the women whose work they admire.“
Supporting diversity is important to us, so we’re participating in ALD this year. We’ve compiled some stories of women in tech from O’Reilly staff and members of our extended family — you can read about them below.
Before you ask HR to find a developer skilled in a particular tool or language, think about who you really want in that seat.
I had a conversation recently with Martin Thompson (@mjpt777), a London-based developer who specializes in performance and low-latency systems. I learned about Martin through Kevlin Henney’s Tweets about his recent talk at Goto Aarhus.
We talked about a disturbing trend in software development: Resume Driven Development, or RDD. Resume Driven Development happens when your group needs to hire a developer. It’s very hard to tell a non-technical HR person that you need someone who can make good decisions about software architecture, someone who knows the difference between clean code and messy code, and someone who’s able to look at a code base and see what’s unnecessary and what can be simplified. We frequently can’t do that ourselves. So management says, “oh, we just added Redis to the application, so we’ll need a Redis developer.” That’s great — it’s easy to throw out resumes that don’t say Redis; it’s easy to look for certifications; and sooner or later, you have a Redis developer at a desk. Maybe even a good one.
And what does your Redis developer do? He does Redis, of course. So, you’re bound to have an application with a lot of Redis in it. Whenever he sees a problem that can be solved with Redis, that’s what he’ll do. It’s what you hired him for. You’re happy; he’s happy. Except your application is now being optimized to fit the resumes of the people you hired, not the requirements of your users. Read more…
