Ever wondered what happens when two seasoned system administrators and a producer who knows just enough to be dangerous get together for a weekly chat? That’s the premise behind 2.5 Admins, a refreshingly honest tech podcast from The Late Night Linux Family. Hosts Allan Jude and Jim Salter bring their deep, real-world expertise to the table, while Joe Ressington-the “0.5” who can configure a Samba share on a good day-keeps the conversation grounded and relatable. Each episode feels like eavesdropping on a lively breakroom discussion, where the latest headlines in technology are dissected not with sterile analysis, but with the practical, sometimes weary perspective of people who keep the digital lights on. You’ll hear them tackle listener-submitted admin questions, offering solutions that are tried and tested rather than purely theoretical. This isn’t about hype or buzzwords; it’s about the tools, headaches, and occasional triumphs that define life in IT. The chemistry between the hosts makes complex topics accessible, and the blend of professional insight with Joe’s every-user viewpoint creates a uniquely balanced listen. If you’re looking for a tech podcast that feels like talking shop with knowledgeable friends, this is it.
