What this episode covers

Josh Bleecher Snyder, Director of Software Engineering at PayPal, discusses the development of PayPal Beacon, a Bluetooth Low Energy (BLE) hardware device for merchant check-ins, and his prior work at Card.io on mobile computer vision. He details the engineering challenges of using BLE for always-on presence, the security architecture involving cryptographic signatures between the beacon, merchant phone, and PayPal servers, and the decision to use the Go programming language for its concurrency and developer experience. Snyder also covers the transition from founding Card.io to working at a large enterprise, highlighting the cultural shift and the use of tools like Docker and Theano for machine learning.

    #006: Pebble’s Code is Free: Three Former Pebble Engineers Discuss Why It's Important (PART 2/2)

    Brad Murray, former head of Pebble firmware, and Tomas, former developer evangelist at Pebble, discuss the risks and decisions behind building firmware for Pebble smartwatches. They detail a critical OTA update bug that nearly bricked nearly a million devices, which was recovered using a clever BLE-based stack overflow hack. The team also explains how they built a massive developer ecosystem through tools like CloudPebble and the Watch Face Generator, and how they optimized code size to backport Pebble 3.0 to legacy hardware using techniques like Link Time Optimization and bootloader rewriting.
