  • Awesome Tech Information, Too Political

    These guys definitely know tech. I have enjoyed many of their podcasts. But I stopped listening when every episode had political commentary.

    There are plenty of podcasts where divisive politics is discussed. If these guys want to create a podcast to do that, awesome, have fun. But leave it out of tech discussions.

  • Best Nerdy Tech Show

    The 3 (2.5) admin gentlemen are a joy to listen to. Great charisma between the hosts. A little bit of news kinda like the daily show but more knowledge base than that. If you wanna keep up to date with IT security news and get a good laugh, check them out. They even do some free consulting at the end. I look forward to each week’s show.

  • A great podcast covering the spectrum of it including Linux, Windows, and BSD. They share relevant information with sources, and they're not afraid to disagree with each other. Well worth a listen.

Talking Points

Recent interactions between the hosts and their guests.

2.5 Admins 299: RMAggravation
Q: Ziggy asks whether upgrading to GoldenEye 25.10 with a ZFS rewrite would be worth it just for the fragmentation improvement, given their pool setup.
The hosts explain that fragmentation risk depends on workload and pool usage; the ZFS rewrite can help in some scenarios, but it's not a one-size-fits-all solution, and for heavy databases the benefit may vary. They provide a practical approach focusing on record sizes and dedicated datasets to minimize fragmentation.
2.5 Admins 283: FSOD
Q: I have a question about recovering from bad RAM with ZFS.
The best place to start is with a ZFS scrub to verify the checksums.
2.5 Admins 281: Lead The Target
Q: How can I set up different DNS query blocking profiles per VLAN on my home network?
Setting up different DNS profiles may not be practical, and using multiple instances of AdGuard could be a solution, but the hosts warn that security must be carefully considered.
2.5 Admins 279: Short One
Q: What's the one bit of advice you'd have for someone looking to get to your level of professional experience as a sysadmin?
Find things that you actually want to do that involve system administration, do them, and document them.
2.5 Admins 277: Battering RAM
Q: Can you guys suggest a solution for bandwidth monitoring on a medium-sized network, 300 clients?
They recommend using NetTop-NG, a plug-in for PF Sense, to monitor bandwidth effectively.
