Respiratory insufficiency is a medic symptom in which a person gets a reduced amount of oxygen in the blood. This paper reports the experience of building SPIRA: an intelligent system for detecting respiratory insufficiency from voice. It compiles challenges faced in two succeeding implementations of the same architecture, summarizing lessons learned on data collection, training, and inference for future projects in similar systems.

In a harrowing video shared by authorities, a man who was reportedly being pursued by police and swam out to sea to evade arrest found himself being stalked by a shark in the process. Drone footage shows the man swimming roughly a mile out from shore in Surf City, North Carolina, as the predator trails behind him. Zachary Kingsbury of Lynnwood, Washington was pulled over Wednesday during a traffic stop, at which time police observed "illegal contraband" in his vehicle, local ABC-affiliate WTVD reported Thursday. While being questioned, 20-year-old Kingsbury was able to temporarily evade police by foot before jumping into the ocean and swimming some 4,000 feet offshore. Video showing the man swimming out to sea while a shark stalked him a mere 60 feet away was posted by the Port City Daily, an online newspaper for the Cape Fear region.
