@TracketPacer It can run over Ethernet, Token Ring, and Fiber Data Distributed Interface (FDDI) networks and over Apple's proprietary twisted-pair media access system (LocalTalk). 🤣

Just got a notification from my bank about "suspicious activity."

Someone tried to use my card to buy $400 worth of Roblox gift cards. I know exactly who it was. My 10-year-old.

I went into his room. He was on his iPad playing Roblox, very focused, trying to look innocent.

I said "did you try to buy Robux with my credit card?" He said "no."

I showed him my phone with the fraud alert. $400 in attempted charges.

He got quiet. Then: "It was an accident."

I said how do you accidentally try to spend $400?

He said his friend told him how to find saved payment info in the browser. He was "just looking" and then "it kind of just happened."

Then he added: "I only tried to get the medium amount though. Not the big one."

This kid tried to steal from me but showed restraint about how much to steal.

I asked why he didn't go for the $1,000 option if he was already committing fraud.
He said "that seemed greedy. And you might notice."

So he calculated the optimal amount to steal. Enough Robux to matter. Not enough to trigger immediate attention.

He's 10 years old and already understands the concept of staying under detection thresholds.

I should be mad. I am mad.

But I'm also realizing this kid has better operational security instincts than half my IT team.

He committed fraud responsibly. That's somehow worse.

I told him he's grounded from Roblox for a month. And from my laptop forever. He said "that's fair."

Then he asked: "If I had done $200 would you have noticed?" The answer is probably not. And he knows it.

I'm either raising a future cybersecurity expert or a future criminal. Maybe both.

@ShortsleeveMA Get the NFL app and stream any game anywhere without the TV provider/station B.S.

@CheckPointSW's answer to all your issues. 🤦‍♂️

@mrbunnykelly @MLFootball Yup! Had a lady (Giants fan) crying behind me at the game that the Pats were being too rough. Its football, not ballet.

Patriots were on a mission to give every Giants player CTE Monday night

Last week I hosted family for Thanksgiving.

My 12-year-old nephew asked for the WiFi password.

He wanted to play Roblox on his iPad.

I looked at the device.

Unmanaged. No antivirus. No encryption.

I’m an IT Professional. I don't run an open network.

So I didn’t give him the password.

Instead, I spent 45 minutes provisioning a Guest VLAN.

I set up a captive portal.

I throttled the bandwidth down to 56kbps.

Then I blocked all traffic on ports 80 and 443.

He came back crying. He said it wouldn't load.

My sister screamed at me to "just let him play."

I told her that Zero Trust architecture doesn't care about bloodlines.

We didn't have a "fun" Thanksgiving.

But we had a secure perimeter.

You’re welcome for the compliance.

@AdjacentNode It's always the #WiFi, never DNS, DHCP, or the firewall.

@MackenzieWiFi I too had never heard of PANS/PANDAS. Thank you for sharing. Best wishes to your daughter and family as you navigate treatment.

[Peter Mackenzie @MackenzieWiFi]

I don’t normally use social media to share personal family matters, but today is an exception — and I hope you’ll take a moment to read this, as it’s incredibly important to me.

Today is PANS/PANDAS Awareness Day— a condition my daughter has been suffering from for the past three years. It’s a condition that has turned our family’s life upside down and has been stealing my daughter’s childhood.

While PANS/PANDAS is treatable, it is often misdiagnosed. In the UK, it’s still not officially recognised, which means accessing the right treatment is almost impossible.

My daughter, Anna (13), wanted to do something special for Awareness Day to help others understand what living with PANS/PANDAS feels like. She wrote a poem — entirely in her own words — that is honest, brave, and deeply moving. It breaks my heart, but I’m also incredibly proud of her strength and courage in sharing it.

Thank you for taking the time to read and help raise awareness. 💛

@DarchisNicolas Do you foresee a shift from 17.12.5 to 17.15.4 soon?

[WirelessNerd @Wirelessnerd]

Bahahah. @JuniperNetworks doing what they do at #CiscoLive baggage claim in San Diego!!

@ us next time...

also, we honestly didn’t know you were still open. congrats!

Every couple of years, I write about Wi-Fi and health — because the myths just won’t quit. Whether it’s headaches, cancer, or mysterious “energy sensitivity,” #WIFi seems to get blamed for just about everything (including my receding hairline). So I decided to tackle the myths again — with facts, physics, and yes, a little fun.

In my latest @ExtremeNetworks blog, I cover:

✅ The real-world power levels of Wi-Fi RF energy
✅ What the FCC and Wi-Fi Alliance say about safety
✅ And how to separate facts from fear-mongering

@Mac_WiFi Thanks, it was tongue in cheek.
