A skeleton for a gradle file to augment ExtJS's Sencha Cmd-generated build scripts. This particular one assumes the application is in a workspace.
ant.importBuild 'build.xml'
def packages_dir = file('../packages')
clean {
doLast { delete 'bootstrap.js', 'bootstrap.css', 'bootstrap.json' }
}
refresh {
inputs.dir 'app'

Afuse sshfs automounter (/usr/sbin/mount.afuse)
#!/bin/bash
# afuse-sshfs mount helper to automatically mount remote machines.
# It is intended to be used as mount.afuse in command line. F.e. in /etc/fstab you may mount directory like:
# afuse# /mnt/remote afuse auto 0 0
# And then as regular user just do:
# $ cd /mnt/remote/user@remote.host/remote/path
# and folder /mnt/remote/user@remote.host will be mounted automatically!
#
# On Mac some also recommend add defer_permissions,noappledouble mount options.

Types of index scans

Indexes

Sequential Scan:

  • Read every row in the table
  • No reading of index. Reading from indexes is also expensive.
