Flash bios Dell Latitude E4300 running Fedora 17

I did not figure this out on my own. I cobbled together information from a few sources. Run the first six steps from here (listed below). To get my new menu item to show up upon boot, so I could actually flash the bios, I started with 3.2 here. I simply added the menuentry {} section listed in step 2 below. I then ran grub2-makeconfig.
  1. Get the bios update from Dell (exe file)
  2. Get biosdisk from the Dell projects site[1]
  3. Get "memdisk" (Fedora: "syslinux" package)
  4. modify the biosdisk script, set the "baseDir" variable (first line after the comments) to the directory to which you extracted the biosdisk archive. The other option is to copy dosdisk.img to the default location ("/usr/share/biosdisk").
  5. Create a bootdisk as root: "./biosdisk mkimage <exe filename>"
  6. After the last step there should be a img file in /tmp (e.g. "E4300A24.img") which contains the bios flasher program. Move that file to /boot.
  7. As root, cp /boot/grub2/grub /boot/grub2/grub.ORIG
  8. Copy memdisk to /boot: cp /usr/share/syslinux/memdisk /boot
  9. Edit /etc/grub.d/40_custom add
    menuentry 'Dell Bios Update A24'{
     linux16 /memdisk
     initrd16 /E4300A24.img
    }
  10. grub2-makeconfig -f /boot/grub2/grub
Reboot. You should have a menu option 'Dell Bios Update A24'. Select that and press enter.

Database, schema, and table sizes in Greenplum

Starting in the 4.x release, you get size info from the gp_toolkit schema. To get the size of all databases and their size in bytes: select sodddatname, sodddatasize from gp_toolkit.gp_size_database; To see the database size in GB, TB, and/or MB. TB: select sodddatname, (sodddatsize/1073741824)/1024 AS sizeinTB from gp_toolkit.gp_size_of_database; GB: select sodddatname, (sodddatsize/1073741824) AS sizeinGB from gp_toolkit.gp_size_of_database; MB: select sodddatname, (sodddatsize/1048576) AS sizeinMB from gp_toolkit.gp_size_of_database; For schema sizes , connect to your database and run: TB: select sosdnsp, (sosdschematablesize/1073741824)/1024 AS schemasizeinTB from gp_toolkit.gp_size_of_schema_disk; GB: select sosdnsp, (sosdschematablesize/1073741824) AS schemasizeinGB from gp_toolkit.gp_size_of_schema_disk; MB: select sosdnsp, (sosdschematablesize/1048576) AS schemasizeinMB from gp_toolkit.gp_size_of_schema_disk; If you want a specific schema only, add

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.
