Google has just release performance data for its Tensor Processing Unit (TPU) custom machine learning chips.

TPUs are

  • 15-20x faster than GPUs and CPUs when running deep learning applications
  • 30-80x more power efficient (operations per Watt)
  • frugal in terms of lines of code required to control them (their deep learning applications are implemented using 100-1500 lines)

Google claim that without these chips they would have to double the number of data centers they run.

I thought the CIA’s “best practices” for coding malware were interesting.

It’s basically a list of things you have to consider when dealing with a sophisticated attacker. Basic audit features aren’t enough if your data and systems present an attractive target.

UK’s National Health Service loses data—old skool

March 2, 2017 By editor

Over half a million UK National Health Service (NHS) records went missing between 2011 and 2016.

When I first skimmed the headline, I was thinking “Another data breach…[yawn].” But, turns out it was all paper. 500,000 paper records went missing.

A private mail direction company sent the records to a warehouse. They had either been incorrectly addressed or the associated patients had moved surgery. Unfortunately, the records—including test results for serious illnesses—were abandoned at that point.

A review is underway to decide whether any patients died due to the missing documents.

You can see how databases are overlooked—the information is pretty abstract. But, a mountain of 708,000 documents (there were administrative documents as well)?! Who walked by that every day without asking questions?
