Recent Biohacks in the News

In this podcast, the Radio Free HPC team looks alarming new hacks of health care data.
  • Henry points us to a story about a PET scanner hack that exploited Windows 7. He thinks a better design would be to have the device send data only. Shahin thinks that this kind of problem with I0T will require us to have different approaches for "Big T" things like mainframes and "Little T" things like sensors.
  • Rich is intrigued by the recent story that biohackers were able to put malware into synthetic DNA that can infect and take over a gene sequencer device.
After that, we do our Catch of the Week.

A Look at Floating Point and Posit Computing

In this podcast, the Radio Free HPC team looks at the problems with IEEE Floating Point.

"As described in a recent presentation by John Gustafson, the flaws and idiosyncrasies of floating-point arithmetic "constitute a sizable portion of any curriculum on Numerical Analysis." The whole thing has Dan pretty worked up, so we hope that the news of Posit Computing coming to the new processors from Rex Computing will help. The A*STAR center at the National University of Singapore will be one of the first to test out Rex machines later this month."

After that, we do our Catch of the Week.
