  • Jim thinks Atari ST and Amigas are 8 bit?!

    Enjoyable shows and interesting themes, but Ep300 was unforgivable. Jim says Atari ST’s and Amigas are 8 bit?! As everyone knows…they are of course 16 bit. Everything I ever heard on this podcast is now in question. How can I ever move on from this?

  • 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.

Talking Points

Recent interactions between the hosts and their guests.

2.5 Admins 304: Wiring a House
Q: What a home rack setup should look like and what to consider when selecting a rack or cabinet.
Use a proper four-post 19-inch relay rack, size 12U to 42U, with shelves and a stable mounting approach; avoid two-post racks, consider depth of devices, and plan for future growth with decent shelves to support weight and ease of maintenance.
2.5 Admins 304: Wiring a House
Q: Guidance on how many and where to place access points for reliable coverage.
Aim for an access point in most rooms, ideally one in every room if possible, with inexpensive APs providing better coverage than a few high-end units; avoid too few APs to prevent dead zones and ensure redundancy in case one AP fails.
2.5 Admins 304: Wiring a House
Q: Should you install Power over Ethernet everywhere or only where needed, and what to consider with PoE.
Go with PoE capability across all relevant runs if possible, since it adds convenience for IP cameras and other devices in the future; the primary constraint is having a PoE-capable switch and sufficient ports, not special cabling beyond standard Cat5e/Cat6.
2.5 Admins 304: Wiring a House
Q: Morgan's question about what cable categories to use for wiring the house, and how to future-proof without overspending.
The hosts recommend Cat6 as a sensible default, warn against over-investing in Cat7/Cat8 for typical homes, and suggest using flexible conduit (Smurf tubing) to allow future cable upgrades without tearing walls. They advocate planning for future speeds but balancing cost, with emphasis on practical upgrades like conduit and modular faceplates.
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.
