• referencing desired objects in namespaced functions

  - by RyOnLife

  I'm having trouble referencing the desired object when I've namespaced functions. No problems here: obj.test = function() { // this == obj } But I'm getting tripped up when I namespace: obj.namespace.test = function() { // this == namespace } In the latter example, I know this references namespace, but I want to reference obj. How can I do it?

• Why is one query consistently ~25ms faster than another in postgres?

  - by Emory

  A friend wrote a query with the following condition: AND ( SELECT count(1) FROM users_alerts_status uas WHERE uas.alert_id = context_alert.alert_id AND uas.user_id = 18309 AND uas.status = 'read' ) = 0 Seeing this, I suggested we change it to: AND NOT EXISTS ( SELECT 1 FROM users_alerts_status uas WHERE uas.alert_id = context_alert.alert_id AND uas.user_id = 18309 AND uas.status = 'read' ) But in testing, the first version of the query is consistently between 20 and 30ms faster (we tested after restarting the server). Conceptually, what am I missing?
