Unable to log into OS X

Ran into a problem with being unable to log into an OS X machine joined to an AD domain. I had previously logged in successfully with this account. Logged in as a local administrator on the machine and noticed the account was no longer listed in System Preferences/Accounts but other domain accounts were, odd.  Ran dscl . -list users and the account was listed. There was also a directory structure under /Users/userid. Ran dscl . -delete /Users/userid and was then able to successfully log in and the home directory was untouched so no data was lost.

Greenplum update with multiple tables

Recently ran into an issue using Greenplum to update a column. I had column1 in tableA that needed to be set to the value of column1 in tableB. Finally came across the correct syntax here . This is what I was looking for: UPDATE tableA  SET col1 = tableB.col1  FROM tableB  WHERE tableA.col2=tableB.col2;

Show running queries on Postgresql/Greenplum

I've got some queries that run for a long time. Sometimes longer than others. I wanted to see how long active queries have been running. Here's a view to consistently do that: CREATE VIEW public.view_activequeries AS ( SELECT age(query_start, backend_start) AS queryage,* FROM pg_stat_activity WHERE current_query NOT LIKE '%IDLE%' ORDER BY queryage DESC); Then you just run: select * from public.view_activequeries; You get a list of all active queries in descending order of how long they have been running, i.e. longest running queries listed first.
