When back in 2021 I wrote an article about how to handle factory reset on surplus Ruckus R700 access points, I was writing with an audience in mind of... myself.

Many years ago, when I was but an infant, the first computers were connected on the ARPANET - the seminal computer network that would eventually evolve to become the Internet.

About four months ago I bought a Lynovation CTR2-Dial controller as a control surface for SmartSDR on iPad.

A week ago I wrote an article about LetsEncrypt ending OCSP service.

In a group chat today, someone asked about the recent dispatch from LetsEncrypt about ending OCSP service.

Maybe you're a fan of Huy Fong "Rooster" Sriracha (which I never really understood the hype around), and are now being bitten by the 2024 shortage.

Looking for a freshly booted headless Raspberry Pi on your lan?

For some reason, ham radio operators cling to an archaic way of measuring whether things are A-OK with an antenna system, called Voltage Standing Wave Ratio, or SWR for short.

Still think that the DoD 7-pass random data erase is the gold standard?

You turned on ssh by touching a file called ssh in the FAT-formatted boot partition, but you still can't log in, right?

My father passed away on April 24th 2023 a week short of his 87th birthday after many years fighting Parkinson's Disease.

It's often convenient to do a quick check (generally on someone else's mailbox) to see if they just deleted all their mail or whatever.

At ClueTrust for better or worse we've standardized on Ubiquiti Edgerouters (mostly ER4s) for SOHO use.

Sorry for the blog drought.

This is a companion to my previous post about setting up a Raspberry Pi for a dedicated headless shack computer.

I haven't written that much about amateur radio here, but that's going to change.

For several years now I've kept a "utility Pi" around - a Raspberry Pi that runs some random housekeeping stuff at my residence.

Important: On the off chance that you know my parents or sister, please don't mention this to them until after the holidays as it's meant to be a surprise!

Tripping over one's own shoelaces while using Git is a common pastime, if not an enjoyable one.

A popular aphorism is "There is no 'Cloud' - it's just someone else's computer".

Dovecot Pigeonhole is an implementation of the Sieve domain-specific language for server-side filtering of mail.

There are a whole bunch of tools out there for printing out the content of all certificates, but the one I've habitually used is openssl x509 -text -noout < server.crt.

Monday Night Football started airing in 1970. 51 years hence you'd think that Tuesday Morning Quarterbacking would have replaced Monday Morning Quarterbacking in the popular vernacular but it hasn't.

It's been about a decade since Randy Bias of CloudScaling first made the "pets vs cattle" metaphor when describing how cloud infrastructure should be managed.

Due to an acute shortage of desk space, Kim and I decided that we were going to run our M1 Mini headless for the time being.

Why on earth would I want to virtualize a Raspberry Pi on a Pi?

Tonight, Lisa brought over some Ruckus R700 access points to be password-recovered, reflashed, and configured to integrate with their network at home.

I recently installed a stereo in the old pickup truck.

A month and a half ago, we had a socially distanced going-away party for a colleague, in a pavilion at a park.

We just got an Apple Silicon Mac Mini.

A popular slide for conceptualizing how many addresses are in an IPv6 /64 (64 bits of network, 64 bits of host) claims that if you filled all five Great Lakes with M&Ms, that would be approximately 2^64 M&Ms.

ClueTrust doesn't run certbot as a general rule (I've written about why in the past) but sometimes it is necessary to run it in an unusual application that is not part of our ordinary automation stack.

I've seen a lot of wharrgarbl in the last few days that boils down to "AWS must do better!"

I've had a couple of friends recently check in with me for guidance on specifying some non-standard circuits and receptacles in kitchens and garages as part of a remodel.

A couple weeks back I bought a "running-but-fix-er-up special" MS460 chain saw for a reasonable price.

I've previously written about Electrify America and their usurious and misleading fees for fast charging.

A week ago last Friday I sat in (but didn't drive) Wes' new Tesla Model Y.

Every so often, terms of art annoy me enough that I go off on a rant or blog about it.

Until recently I had been reliant on random Perl and Python one-liners to generate $5$ and $6$ hashes (as well as $1$ - AHEM, Juniper...) when I needed to email someone a password or set up Ansible for mail accounts on SmartOS.

When I was a teenager, I got pretty good at tracking down parasitic draws in older cars with flakey wiring harnesses by pulling (tubular glass cartridge) fuses one at a time and reading the wiring harness schematic.

A couple of months ago I became a Signal user.

A couple of years ago when Argos was a puppy, he chewed on my Ridge Wallet and put a bunch of tiny puppy-teeth-sized dents in the titanium side panels.

Here at ClueTrust we have been using Ansible for several years now.

Yesterday I dropped by the BP station in Warrenton to pick up a gallon of ethanol-free gasoline for the chain saws and string trimmers.

About a year ago I came to realize that I didn't have the right license for operating a particular truck that I'd been driving periodically for a number of years.

A bit over four years ago I fired Drupal in favor of Jekyll.

The other day I decided that I'd take advantage of my employee discount on FiOS, offered through my job.

At ClueTrust we’re constantly re-evaluating our security posture based on both perceived threat and what level of effort it takes to implement various security technologies.

A year and a half or so ago we bought some secondhand Juniper EX4200 switches for deployment to do OOB, camera, wifi, and other applications where inexpensive POE switches were appropriate, and the fact that they were EOL didn't represent a barrier to acc…
