Adding to this, don't automatically include <wait for laughter> in your joke delivery. Make the joke - if it lands and the audience is laughing, you can pause until it dies down. If the joke doesn't land, you just move on and everyone will forget about it.

Which is the same constraint as pretty much any other physical item one might purchase. "reasonably a forever" is a reasonable description.

While converting a bridge to tunnel mid-construction doesn't happen, what does often happen is that design assumes a particular construction technique can be used, construction starts with that technique, and midway through it's determined that an entirely different technique is required. This results in a bunch of redesign, remobilization, etc. Just like with software, construction often does not survive first contact with reality.

These can be run in reverse as well, it requires CB custom electronics so it’s not something a lay person can do out of the box.

Source: I used to measure the “microphone” frequency response for a kiosk OEM.

Noise from data centers is a real issue, but Benn's measurements and analysis are not great (speeding up the sample rate to demonstrate frequency effects is just wrong, among other issues).

Count me in this group. I wound up buying the 13 mini right before it was going to be discontinued because I knew that would be the last small phone they would produce and I'm keeping it until it dies (or I can't get a battery for it).

Again, it's not just "potential suspects" it's potential witnesses, or identification of potential casualties. I don't feel great about state actors of any type using facial ID, but I can think of any number of reasons why a FD might use it in the course of their duties, and I would much prefer they have it over the PD.

Part of the investigation is determining whether the event is actually a crime. I'd much rather have subject matter experts make the determination of arson vs. act-of-god rather than "every nail needs a hammer" police force.

You mean an expert in acoustics related to those areas? There are lots of experts and researchers. Take a look at the Acoustical Society of America, the Institute of Noise Control Engineering, and Council for Accreditation in Occupational Hearing Conservation for starters.

Penn State, University of Hartford, Purdue University, Michigan Technological University, University of Nebraska, Morgan State Univeristy, and Brigham Young University (among others) all have strong acoustics programs with research in a bunch of areas.
