China wants tech companies to monetize data, but few are buying in

I find China’s attempt to treat data as a formal business asset quite interesting, especially given the massive amount of data the country generates. Companies seem reluctant to adopt this policy though, with only 283 out of 60 million companies participating. But it is still early days, and the months and years to come will (…)

Reviewing the Cryptography Used by Signal

Soatok is an opinionated cryptographer, but a very good one. After having looked and complained about many ‘private messenger apps’, he has a grab at Signal. But he leads us through his non-findings in a very nice way, which also shows how Signal’s cryptography is chosen and made secure. A very intense and technical read (…)

US immigration is gaming Google to create a mirage of mass deportations

A very dark example of search engine optimization (SEO): Ice is suspected of updating time stamps of reports on old operations to push them up in Google searches.
