127: More Server Talk with Brian Moses

In this weeks episode we are again lucky to be joined by Brian Moses, to continue our discussion on building your own home server. We start off by highlighting what ECC memory is and its’ value in a home server setup. Following this, we chat about looking into the second-hand market for hardware components - as an option to find a good deal. This leads us on to discuss overclocking hardware, threads vs. cores within a CPU and what Hyper-threading actually is. Finally, we mention some different NAS Operating System solutions and Brain’s foray into the world of Quadcopters.

126: 19th January 2038: The End of Time

In this weeks episode we start off the podcast with discussion around Timezones, Daylight saving time and how the Year 2038 will be an interesting one.

Finally, we highlight the differences between Software/Hardware video-decoding and some interesting PHP function aliases.

125: Building a Server with Brian Moses

In this weeks episode we are joined by Brian Moses to discuss all things server development. We start off the show by highlighting how he got into computers and what drew him to blogging about DIY NAS builds. From here we touch upon the key areas of consideration when deciding on hardware (Motherboard, CPU, RAM, Storage) for a server. Finally, we discuss the concept of RAID, the FreeNAS operating system and how he performs burn-in testing on recently built systems.
