Remove an item from array using UnderscoreJS

arr.splice(_.findIndex(arr, { id: 3 }), 1);

var index = _.findIndex(arr, { id:...

PDO MySQL: Use PDO::ATTR_EMULATE_PREPARES or not?
...er using the binary protocol. In other words, the same PDO code will be equally vulnerable (or not-vulnerable) to injection attacks regardless of your EMULATE_PREPARES setting.

Java: Date from unix timestamp
... time-of-day value of 22:30 instead of the 18:00 seen here. I suspect your PHP utility is implicitly applying a default time zone to adjust from UTC.
