    Ivy Insights

    The 2.5 Admins podcast brings together three seasoned professionals, Allan, Jim, and Joe, in a fantastic show that combines their expertise and sense of humor. With a range of experience on various systems and a diverse perspective on technology, these hosts never fail to educate and entertain their listeners. As an industry professional, I find value in their informed opinions and real-world experience shared in every episode.

    One of the best aspects of The 2.5 Admins podcast is the wealth of knowledge and experience brought by each host. Allan is legendary in the BSD/ZFS world, Jim has an insatiable curiosity for all things tech, and Joe offers a "man on the street" Linux perspective. This combination ensures that listeners can expect informative discussions that touch on a wide range of topics. Additionally, the hosts' different perspectives on how to approach similar tasks provide unique insights and make for engaging conversations.

    While The 2.5 Admins podcast offers great content overall, it does have some areas for improvement. Occasionally, the pacing of the show can feel uneven or rushed, which may leave listeners wanting more depth on certain topics. Additionally, there could be more diversity in guest speakers to bring fresh perspectives and expand the range of discussions.

    In conclusion, The 2.5 Admins podcast delivers informative and engaging content with hosts who have a wealth of knowledge and experience in the field. Whether you're a sysadmin looking to learn something new or simply interested in tech discussions from industry professionals, this podcast is worth listening to. While there are areas for improvement such as pacing and guest diversity, overall it provides valuable insights that make it worth including in your regular listening lineup.
