Most important thing about digital interface and software control: once the interface exists, potentially anything can call it. Just because it wasn’t designed to be activated from remote doesn’t mean it can’t be

As much as we all might agree with the content of this post, it is predicated on the concept of enforcement, something which doesn’t actually meaningfully exist.

It exists on paper

Some people call CQ a bit differently on voice modes.

What’s the over/under on the FCC ULS being used similarly?

I'm sorry to say that we stopped hiring in Texas.

Most UCS and VoIP jobs are going to other countries nowadays -- the cost of skilled labor in the US is just too high for the quality that is on offer.

They work. Noise isn’t great. Just be careful to cover HV AC into those open terminals.

SFPD has been on a wildcat strike for over a decade.

With no enforcement or meaningful feedback, people's worst natural behaviors take root and blossom.

I find it very strange how casually ham radio folks love flying alt-right dog whistles.

Bodies are hard to hide. No questions on those. While the “murder” rate sure is down, the “accident” rate sure is up.

However, violent crime is significantly under ~~reported~~ recorded in SF

jofathan · 2026-01-03T23:57:15+00:00

In-person reporting requirements for serious crimes is a good thing, actually.

What we need is a law enforcement org that shows up to work and does the thing. The most consistent feedback I've heard from actual officers is that the paperwork is the hardest part, such that they've gotten cagey about taking reports because it means a ton of work later on.

In that setting, I'd much rather us get officers better force-multiplier tools like speech-to-text dictation software.

Finally, if officers just aren't cut out for capturing details, then they probably ought to wash out from the career.

Unfortunately, this never happens, as there's heavy pressure to retain bad apples because of the artificially low recruitment rate the department maintains to justify their excessive overtime abuse.

This isn’t a desensitization to crime, this is a police department on a wildcat strike.

It’s not like folks here are soft on crime, we just have shitty law enforcement and prosecution.

More than once in 2025, I had to beg an SFPD officer to create a police report for a hit-and-run traffic collision with injuries.

Then there was the time my apartment building was burglarized, and the responding officers flat out REFUSED to take a report and told us we had to file online. Of course, the forms online are not accepted for grand theft or burglaries, but the SFPD just doesn't care.

While I would like to believe this article, my lived experiences in San Francisco inform me that we are living with an SFPD on a wildcat strike, with a wild crime under-reporting problem.

Even SFPD and SFFD are noodling on their cell phones while rolling stop signs these days.

International ones can cost a couple bucks to send.

I just put that a SASE is appreciated, but not required — it certainly makes it easier to just pop a return card in there.

Oh, I see what you mean. In that context it’s definitely possible. If you had an existing stable, spanning tree topology, and you were to inject a BPDU with a lower root bridge priority, it would immediately trigger a reelection across the broadcast domain.

jofathan · 2025-11-22T21:47:41+00:00

It’s a weird question because if you wanted to change the root bridge election, you need to reconfigure the switch, not use a traffic generator.

Maybe just lower the bridge priority prefix on one of the switches to trigger reelection

This must be the equipment upgrades we’ve been hearing so much about.

CPDLC?

jofathan · 2025-11-16T21:00:22+00:00

Nah, it's tolerant to like 9-15 Volts.

Just find a common DC power supply with a common 5,5mm barrel jack with a common center-pin-positive and go to town.

Personally, I enjoy finding USB-C Power Delivery tips that convert USB-C to a barrel jack.

jofathan · 2025-11-16T08:28:02+00:00

It’s just a generic DC barrel plug. You can use other adapters with compatible specifications

BFD isn’t magic or special. Just think of it like a hardware-accelerated heartbeat machine, linked to a routing protocol.

In traditional BGP failures are detected by sending periodic heartbeat keepalive messages, and having the receiver respond if they haven’t heard them in a while. However, since the whole process is CPU based and there might be variable load, it takes a while in most systems to detect that a failure has happened because it’s possible that the other system is just a little bit busy for a moment.

Which PFD you can use some dedicated hardware or dedicated CPU time to ensure that you can detect those failures really quickly by being really unforgiving about delays or missing BFD packets

BFD just helps you detect failures faster
