- Talking to Big Machines (Jon Bruner) — “Selfless machines” coordinate across networks and modify their own operation to improve the output of the entire system.
- Docker Security — Containers do not contain and Stop assuming that Docker and the Linux kernel protect you from malware.
- Your Voice Assistant is Mine (PDF) — Through Android Intent mechanism, VoicEmployer triggers Google Voice Search to the foreground, and then plays prepared audio ﬁles (like “call number 1234 5678”) in the background. Google Voice Search can recognize this voice command and execute corresponding operations. With ingenious designs, our GVS-Attack can forge SMS/Email, access privacy information, transmit sensitive data and achieve remote control without any permission.

Adding consistency to Kivy's Python UI tools
Kivy has a wonderful set of built-in widgets that can be extended in numerous ways. They have very useful behaviors, but their look and feel may not integrate well with your App or the platforms you are targeting. Kivy doesn’t support theming out of the box right now, but if you poke around enough, there are a range of options you can use to customize the default look of widgets without having to define your own inherited versions of them.
I’ll first introduce you to Kivy’s image atlases, which are less mysterious than they sound, and are important groundwork for understanding theming in Kivy. Then you’ll learn two different ways to do manual theming in Kivy, with an eye to future automation.
To understand theming, you must first understand atlases. An atlas is essentially a collection of distinct images combined into a single image file for loading efficiency. A JSON file describes the location of the separate images inside that master image file so that Kivy can access them directly. If you’ve ever worked with CSS sprites, you know exactly what I’m talking about. If you haven’t, the following example should explain everything.
Tips and tricks to squeeze the most out of your mobile UI
Editor’s Note: Mobile HTML5 is a book by front-end engineer and frequent speaker Estelle Weyl. It is packed with hands-on examples to make you a stronger web developer–including best practices for SVG, Canvas, and CSS3 tailored to fit mobile devices. In the excerpt below, Estelle walks you through five easy things you can do to improve battery life in your mobile web apps. As throughout the book, the tips she provides come from her own real-life experience with these technologies.
Unlike desktop computers that are tethered to the wall at all times, and even laptop computers that are generally used by stationary users, mobile users do not recharge their devices throughout the day. Mobile users expect their devices to last, at a minimum, 24 hours between recharging.
Your users do realize that calls and GPS usage consume battery power. However, if they think they’re just using their browser to surf the Web, they don’t consider that different websites will drain their battery faster than other sites. It is our job, as developers, to manage the power consumption of our code. Read more…
