- Fast Lomb-Scargle Periodograms in Python — a classic method for finding periodicity in irregularly-sampled data.

- Industry 4.0 — stop gagging at the term. Interesting examples of connectivity and data improving manufacturing. Human-machine interfaces: Logistics company Knapp AG developed a picking technology using augmented reality. Pickers wear a headset that presents vital information on a see-through display, helping them locate items more quickly and precisely. And with both hands free, they can build stronger and more efficient pallets, with fragile items safeguarded. An integrated camera captures serial and lot ID numbers for real-time stock tracking. Error rates are down by 40%, among many other benefits. Digital-to-physical transfer: Local Motors builds cars almost entirely through 3-D printing, with a design crowdsourced from an online community. It can build a new model from scratch in a year, far less than the industry average of six. Vauxhall and GM, among others, still bend a lot of metal, but also use 3-D printing and rapid prototyping to minimize their time to market. (via Quartz)

Exploring the new Android M battery performance features.
It has been a long held personal belief that most battery drain issues on smartphone devices are due to applications that are improperly tuned. I work very closely with mobile developers to help optimize mobile apps for speed and battery life with AT&T’s own Application Resource Optimizer. I am also in the process of finishing up a book on High Performance Android Apps that will be published later this summer. So I am always excited to see mobile application performance hit the center stage.
Last month, Google held its annual Google I/O conference, where they announce new products, tools and features. This year, with the release of the Android M developer preview, performance of mobile devices/battery life and app performance were on the center stage (and unveiled at the keynote!). Lets look at the new features and tools available to users and developers to make Android’s battery life better.
Enhance the user experience with the thoughtful use of sound.
It’s definitely a fun toy to play with, but most of us probably couldn’t think of how this might be relevant to our jobs. When I presented 8-bit game music with the Web Audio API at last year’s Fluent Conference, I readily admitted that it was intended to be purely fun rather than practical.
Recently I explored the idea of adding audio to web apps, but I think the big problem isn’t that web developers were unsure how to add audio to their app, but that they don’t think they should add audio to web apps. In this article, I’d like to make the case that you should be considering audio when designing your web application user interface.
