Wireless access point refreshes sound simple on paper: buy new hardware, swap it in, done. In practice, your Meraki AP migrations will likely turn up a few real-world wrinkles. Here is a process you should follow to get everything cut over cleanly with zero extended downtime for your end users.
There's a persistent narrative in the PC building world that goes something like this: if you're serious about your system, you need liquid cooling. It's the kind of advice that gets passed around forums, Reddit threads, and YouTube comment sections with an air of certainty that discourages further investigation. And like a lot of conventional wisdom in tech, it's not exactly wrong; but it's not exactly right either.
The truth is more interesting, more nuanced, and more useful to anyone actually trying to make a smart purchasing decision in 2026. So let's break it down.
Power over Ethernet (PoE) is one of the most quietly transformative technologies in modern networking. It lets you deliver both data and DC power over a single Ethernet cable, eliminating the need for dedicated electrical outlets at every access point, camera, phone, and sensor in your environment. What started as a modest 15-watt convenience in 2003 has grown into a family of standards capable of pushing nearly 100 watts per port; enough to power laptops, LED lighting panels, and multi-radio Wi-Fi 7 access points.
But here's the thing: the terminology around PoE has gotten messy. Between IEEE standards, vendor-specific branding, passive PoE injectors, and marketing names like "UPoE" and "PoE++," it's easy to lose track of what actually matters when you're speccing out a deployment.
This guide breaks down every major PoE standard, protocol, and power type; what it delivers, how it works, and when you'd actually use it.
Are you looking for a way to keep your sensitive files hidden from prying eyes? Whether it's financial documents, personal photos, or top-secret projects, sometimes you just need a locked folder.
If you are running Windows 11 Pro or Enterprise, you are in luck! You don't need to download any sketchy third-party software. Instead, you can use built-in Windows tools to create a BitLocker-encrypted Virtual Hard Disk (VHDX).
Think of this as a secure digital "file vault" that lives on your computer. When you need it, you enter a password to open it. When you're done, you lock it up, and your files completely disappear from view.
If you've ever wrestled with port forwarding, dynamic DNS, or a clunky traditional VPN just to reach a device at home or a server at work, Tailscale is about to change your life. It creates a private mesh network (called a tailnet) across all your devices, wherever they are, with no open ports and no complex firewall rules. It just works.
This guide covers everything: creating and securing your account, installing Tailscale on Windows, Linux, virtual machines, and Docker containers, and hardening your tailnet so it's both maximally secure and actually pleasant to use.
Over the last six months, I've been seeing more and more DNS hijack infections on routers, switches, and servers. It's a genuinely clever tactic, and it's worth understanding why: the attacker only needs to briefly gain access and very lightly maintain it. Once they've rerouted your DNS to a server they control, they can quietly sit in the middle of your traffic and analyze your traffic packets, harvest credentials, the works.
This isn't theoretical, and it isn't rare.
My own server and three customer servers have been hit by this class of attack in the last 3 months. I'm writing this to bring some attention to what's going on, explain how these attacks actually work, and (most importantly) show you how to defend your equipment and check whether it's already been hit, without needing to be a network engineer.
After 20+ years running Pacific Northwest Computers, I've installed, uninstalled, and re-installed a lot of "must have" Android apps. Most of what gets marketed as a "hacker toolkit" on the Play Store is either abandoned, repackaged, or outright malicious. So I figured I'd share the apps that have actually earned a spot on my phone for use all of the time, or just if/as needed. Nonetheless, these are the ones I can and do reach for during client visits, network troubleshooting, and security work.
