How to delete contacts on a Mac computer, or entire groups in the Contacts app

  • The Contacts app on your Mac computer is extremely easy to use, and once you've learned the basics, you will be able to create and delete contacts in just a few moments.
  • Just be aware that you can't delete contacts in "read-only" accounts, like Google or Yahoo, via the app.
  • You'd have to go into those accounts to delete those contacts.
  • With that in mind, here's how to delete contacts from your Contacts app.
  • You can use the same method to delete groups, but instead of selecting a contact, you'd select the group and then hit the delete key.
  • However, there is an exception: If your group is used in a Smart Group, you would have to first go in and edit or delete the Smart Group before you would be able to delete the group.

Apache Airflow Tips and Best Practices

  • In Airflow, a DAG is triggered by the Airflow scheduler periodically based on the start_date and schedule_interval parameters specified in the DAG file.
  • The first DAG run would be triggered after 7 am on 2019–12–06, at the end of its schedule period, instead of on the start date.
  • Based on Airflow’s scheduling mechanism described above, you should always use a static start_date for your DAGs to make sure DAG runs are populated as expected.
  • After materializing DAG run entries of a DAG, the Airflow scheduler will “backfill” all past DAG runs whose time dependency has been met if catchup is enabled.
  • Because Airflow can backfill past DAG runs when catchup is enabled and each DAG run can be re-run manually at any time, it is important to make sure DAGs are idempotent and each DAG run is independent of each other and the actual run date.

How to delete files on your Chromebook in 5 simple steps

  • When you're new to the Chromebook system, even doing something as simple as finding and deleting unwanted files can feel like a bit of a chore.
  • But once you get the hang of the interface, it's quite easy.
  • Before you delete anything, however, be aware that Chromebooks do not have a trash can or another place where deleted files can be retrieved from — so you'll have to make sure you really don't need the file before selecting the "Delete" option.
  • Regardless, it's a good idea to backup your files to Google Drive just in case you do end up needing them later.
  • With that in mind, here's how to delete files.

Disposing of Virtual Disks Is as Essential as Disposing of Hard Drives

  • There are, however, several best practices that you can use to ensure that deprovisioned virtual hard disks do not pose a significant security risk to your organization.
  • One easy way to do this is to use File Explorer to map a path to the virtual hard disk’s location, right click on the disk, and select the Mount command from the shortcut menu.
  • When you are done, right click on the drive letter that represents the virtual hard disk, and select the Eject command.
  • It is worth noting, however, that if the virtual hard disk is stored on a deduplicated volume, the deduplication process may undermine the secure deletion.
  • As important as it is to securely delete unwanted virtual hard disks, remember that the actual deletion is only part of the overall process.
