Now that Juniper is part of HPE, the video which precedes company-wide meetings (webcasts) includes lots of B-roll of HPE discover.

And lots of that B-roll features @thectoadvisor.com.

Nice to see you at our company meetings, Keith :)

A Dyson sphere around the solar system (stop at Neptune) made from a single layer of the foil used for Hershey's Kisses (about half of standard household foil thickness) would require a mass of aluminum slightly larger than the mass of Earth.

Sam Altman should get on this project immediately.

Becca has not stopped talking about meeting you today. "I can't believe the author signed my favorite book!"

Thank you, and Go Knights!

I just explained to my 18 year old that people used to pop their car stereos out of their dashboards and carry them around like little lunchboxes.

I'm not sure she believed me.

Okay.

It's interesting to me. <shrug>

Is "keystroke patterns or rhythms" not at least a bit interesting?

I don't know what the frontend for this thing is, but it suggests javascript (or a fat client?) would be profiling my touch-typing.

I'd not have suspected a text input box of doing biometric profiling. Seems interesting to me.

A memo to Costco employees titled "Employee Preferred First Name is now visible in Timeclock & Timekeeping System"

A memo to Costco employees titled "Employee Preferred First Name is now visible in Timeclock & Timekeeping System"

In Costco yesterday I noticed a memo on the bulletin board near the timecard clock. It explained how employees can update their preferred first name in the payroll system.

It was a nice bright spot, given (gestures around) everything.

A second hub won't get her there. Gotta have a bridge in the mix to create a *bridging loop*.

Product image of a TOSLINK cable with mini-TOSLINK adapters tethered to each end.

I was astounded ~20 years ago to discover a tiny lens buried deep in the headphone jack of my MacBook.

What is this thing?

Prior to that I'd thought my TOSLINK cable had dust caps tethered to its ends, but they were adapters! 🀯

Something @tracketpacer.bsky.social said caused me to discover that AUI connectors (think: SFP slot in the days of 10Mb/s Ethernet) came with both threaded fasteners and those weird sliding clips.

I don't think I've ever seen a threaded one. Or maybe I dismissed them as "game port"?

You have a second dual-speed hub handy?

This would be an interesting experiment.

I don't know that the cops relied on google maps for this raid, but the correlation and subsequent edit are both interesting.

At any rate, they certainly didn't rely on driving by and checking the address, or reading the numbers next to the door they were kicking in.

Until a few days ago, a google maps search for 489 Vanzant Rd. dropped a pin directly on 511, and 489 was mislabeled as 525.

Google has corrected the error.

Screenshots from December and from today.

KY police shot and killed a man in his home while executing a search for a missing weed whacker a couple of weeks ago.

They were are the wrong house.

They thought they were at 489 Vanzant Rd, but were actually at 511. The house was clearly labeled 511.

So how did this screwup happen?

I sat the CISSP and CISA exams a few weeks apart that summer.

ISC2 booked a ballroom at the Marriott for their exam. Very comfortable.

ISACA booked a classroom in a disused school building with no A/C and no bathrooms.

Sometimes I'm astounded by how good the suggestions are: "That's what I was going to type!"

Sometimes I'm disappointed by how wrong they are.

Infrequently the suggestions are subtlety wrong and I *don't notice the error*

I type faster than I can debug.

For me, there's a net cost to these tools.

I first encountered ISACA in 2007 or 2008 and was thoroughly disillusioned with them in the 6 months or so before I sat for the CISA.

The quality of the prep materials, exam and processes were *so far* behind those of ISC2, while the cost of engaging with them was so much higher.

Garbage org.

I encountered a similar (maybe) mystery recently: 40A circuit tripping regularly with consistent 24A load.

Video of the trip event revealed ONE FRAME with 90A (?!) indicated.

More poking around revealed arcing at the wire/breaker interface.

Loose wire clamp. Tightening fixed it.

Good luck!

I don't recall seeing blue wingtips in previous photos like these.

Is there some interesting airplane news?

The inseam setup primed my brain to read the last word as "jump", and it made perfect sense.

I believe in you. You'll make it. Go for it!

The details were a specific hostname in a temporary server certificate. To provoke the response, the validation host had to say "hello $randomName"

Some web hosts will fabricate an appropriate certificate on the fly, I guess.

As it turns out, some multi tenant web hosts crafted dynamic replies which satisfied the challenge, inadvertently granting evil customers certificates for their innocent victim customers.

Details required to complete the SNI challenge are not communicated exclusively out-of-band. They're also part of the request when validating the challenge.

So, anybody (attacker or otherwise) can respond to the challenge.
