Burn OS X Lion DVD

Here

Nuts and bolts:

1. Once you've pulled Lion down from the Mac App Store, right-click on the installer and select the option "Show Package Contents." This is your Mac's way of tearing the wrapping off a virtual install disk to access all the shiny bits (aka "files") inside.
2. Open the "Contents" folder, then look for a "SharedSupport" folder and open that. Inside, you'll find something called "InstallESD.dmg." This is the money file we're looking for (or the "master control program" if you're a Tron wonk).
3. Copy that file ("InstallESD.dmg") to a folder outside of the installer (your desktop works).
4. Open the "Utilities" folder on your Mac and launch "Disk Utility."
5. Select "Burn" from the "Images" menu option, or just click the yellow and black icon on the menu bar (which, disturbingly, looks just like the official symbol for nuclear activity).
6. Browse to wherever you copied "InstallEDG.dmg" and select that—drop in a writeable DVD, wait for it to burn, and presto, instant bootable OS X Lion DVD!

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.
