At Evernote: The Evernote SDK, Penultimate Image Processing, and Helios

Continuing the momentum from April, we're piling on the power for our May meetup at Evernote. We'll be meeting at the Evernote HQ in Redwood City and starting early - please aim to arrive by 6 so that we can start talks at 6:30.

First, a word from Evernote:

We encourage everyone to have Evernote Hello setup on their phones. We will be using Hello Connect to do a little experiment.

Now, the talks:

The Evernote APIs and SDK for iOS

Then we'll hear about the Evernote APIs and how the Evernote SDK for iOS has evolved. From Evernote:

The Evernote SDK for iOS has added lots of new features that developers can benefit from. With a block-based easy to use API, developers can write great apps that work with the Evernote platform. Also learn about the best practices we follow to maintain open source code.

Reducing PNG Size: A Brief Tale of Image Processing

All apps display images, but if yours has to create or manipulate them at the pixel level, a whole new world opens up. Ben Zotto, the creator of Penultimate will recount a unique voyage of discovery: effectively generating 8-bit quantized PNG files on device from full RGBA images to save space. Waypoints may include Core Graphics bitmap contexts, GCD, NEON intrinsics, and using pseudo-3D texture samplers for fast color mapping. Sound like nonsense? Learn some neat tricks, or tell Ben how to do it better.
