Emerging energy-harvesting devices (EHDs) are computer systems that operate using energy extracted from their environment, even from low-power sources like ambient radio-frequency energy. Future EHDs will be a key enabler of emerging implantable medical devices, IoT applications, and nano-satellites, but today's EHDs operate intermittently, only as environmental energy is available.  Unfortunately, intermittence makes today's EHDs unreliable and extremely difficult to program and debug.  In this talk I will summarize the main challenges of intermittent execution.  I will then discuss our recent efforts developing system, programming language, and toolchain support for EHDs to address the challenges of intermittence, focusing especially on programmability, debugging, and reliability.  I will close by discussing our recent work on building a reliable, EHD-based, hardware/software application platform for an upcoming deployment.
