Sigh.  Today I discovered that the Android emulators with decent performance (x86/HAXM) don't get to use the Google APIs.  I have plenty of devices, but its really nice to be able to test things with just sims.  I guess its also good to test on a non-google api sim, considering the Kindles et al of the world.

interesting, volunteers run park drones because of government regulation on government use of drones.  i suppose drones could be positively transformational.  the reality is we reflect light that comes from the sun and anyone is free to capture that light.  i bet more cars crash into houses than drones.  so, i suppose that even tho i hate surveillance, no one should be taking away safe use of "aircraft" (remember they mostly break when they hit a tree).

its been fun learning the limits of html XXwebviews on mobile. the real limitation in "butter" comes from scrolling handled through javascript. a webview does a wonderful job of providing a long slice of complexly styled information. it scrolls smoothly even on the lowest end hardware. the second you want to put a nav bar at the top or otherwise contain your content in a fixed size div, you are screwed. you have to route touch through javascript. you lose the native feel of fling. the touch events come slowly. some devices have weird bugs with intercepting the native scroll handling. you can do it but your peak frame rate goes from 60 to 20. some times people do a good job faking it: http://cubiq.org/iscroll-4 (note that it is very smooth when you aren't touching the screen... the momentum and overscroll parts pick up the slack for the active drag events)

We all need color Emoji.  Android, Windows, Tizen, and Web.  And hell, even iOS too, another flavor of emoji is always good to have :).

If you make communication software (anything where people post text that others see), you should pitch in.  It lets people be more expressive, and a free set means everyone can easily make their software keep people expressive on all platforms.

Yet again, I have found open-source code to have dangerous surprises.  Can't really complain though, you get what you pay for.

If you have an application on iOS that transforms other images into an offscreen buffer, this might be valuable information for you.  Find where you call CGBitmapContextCreate and its derivatives.  Make sure that you don't take an image from the user (or a 3rd party webservice) and use CGImageGetColorSpace(input_image) as a parameter for creating the offscreen rendering context.  Many images types don't have pixel formats that iOS devices can render to.

In particular, Google provides a default profile image which has uncommon properties.  Their default image is a indexed color PNG (effectively a transparent gif).  Creating a rendering context that targets indexed color is not allowed.
