Most of the time it’s information that’s needed to commit fraud, as happened in 2015 to Experian and the IRS. Sometimes it’s stolen for purposes of embarrassment or…
Uber provides bad advice about PostreSQL vs. MySQL
In the previous Jepsen analysis of RethinkDB , we tested single-document reads, writes, and conditional writes, under network partitions and process pauses. RethinkDB did not exhibit any nonlinearizable histories in those tests. However, testing with more aggressive failure modes, on both 2.1.5 and 2.2.3, has…
When you have to build a web application, you are often asked to add search. The magnifying glass is something that we now add to wireframes without even knowing what we are going to search.
