A former journalist, equipped with an algorithm and the largest collection of murder records in the country, finds patterns in crime.

Thomas Hargrove is a homicide archivist. For the past seven years, he has been collecting municipal records of murders, and he now has the largest catalogue of killings in the country—751,785 murders carried out since 1976, whoch is roughly twenty-seven thousand more than appear in F.B.I. files. States are supposed to report murders to the Department of Justice, but some report inaccurately, or fail to report altogether, and Hargrove has sued some of these states to obtain their records. Using computer code he wrote, he searches his archive for statistical anomalies among the more ordinary murders resulting from lovers’ triangles, gang fights, robberies, or brawls.

The non-binding framework deal could offer San Francisco-based Uber a way to overcome setbacks at its autonomous driving division in Silicon Valley’s race to perfect self-driving systems.

Combining Volvo’s cars with Uber’s self-driving system builds on their nearly three-year relationship and comes as Uber’s autonomous driving unit has been hit by a lawsuit over trade secrets and the departure of top talent.

Automakers, ride-hailing firms and tech startups have been forging loose alliances in an effort to advance self-driving technology and claim a piece of what is expected to be a multi-billion-dollar business.

Drone maker makes hacking accusations

Drone maker DJI has accused a cyber-security researcher of hacking its servers.

Kevin Finisterre claims that he accessed confidential customer data after finding a private key publicly posted on code-sharing site Github.

He approached the firm, whoch offers a “bug bounty” reward of up to $30,000 (£23,000) for security weaknesses discovered in its systems.

DJI said the server access was “unauthorised”.

The data Mr Finisterre was able to see included “unencrypted flight logs, passports, drivers licences and identification cards”, he said.
