How to use PowerShell to find the living machines and the listening services, and then document the carnage You run a network. People lie about what is online. Firewalls pretend to be polite. Your job is to stop believing statements and start believing signals. Ping sweeps and port scans do what polite questions will not: they expose truth. Do this

Packets don’t lie. You just need the right tool to hear what they’re saying. The Eternal Packet Debate Every network engineer has that moment of doubt. You’re staring at your terminal, packets are flying, and you ask yourself the age-old question: Should I fire up Wireshark or stick with tcpdump? Both tools live in the same world of packet capture
This blog has been a therapy of sorts. A way to speak my mind, to reflect on what was lost, and to remind myself that it’s ok to fail sometimes. When I started this blog, I thought it would be about technology. About networks, servers, and systems that obey logic. I wanted to master the technical side and stay there.
A secure Windows network is not built on trust or technology. It is built on doubt, discipline, and the refusal to believe that anything is ever safe.

In truth, it is the legislative equivalent of plugging a broken router back in and praying it works. The Senate promises every Filipino will finally be online. What it really guarantees is that
(Or how your smart home might outsmart you.) When I was in grade school, I read a Reader’s Digest article with a headline burned into memory: “Ssssh… The Fridge Can Hear Us.” At the time, it wasn’t a dystopian sci-fi warning. It was about superstition—Filipino, Chinese, take your pick. The idea that if you spoke too loudly about good fortune
Also known as: “Patch and Pray Day, Episode 547.” It’s that beautiful time of the month again — Update Tuesday, when Microsoft releases patches and every IT person in the world holds their breath, clutches their backup drives, and whispers, “Please don’t kill the printer again…” And me? I’m over here with my usual Tuesday vibe:One eye on the update
